What is a trust? What are the different types of trusts?
[ { "docid": "449081", "text": "\"From a more technical point of view, a trust is a legal relationship between 3 parties: Trusts can take many forms. People setup trusts to ensure that property is used in a specific way. Owning a home with a spouse is a form of a trust. A pension plan is a trust. Protecting land from development often involves placing it in trust. Wealthy people use trusts for estate planning for a variety of reasons. There's no \"\"better\"\" or \"\"best\"\" trust on a general level... it all depends on the situation that you are in and the desired outcome that you are looking for.\"", "title": "" }, { "docid": "534290", "text": "Trusts are a way of holding assets with a specific goal in mind. At its simplest, a trust can be used to avoid probate, a sometimes lengthy process in which a will is made public along with the assets bequeathed. A trust allows for fast transfer and no public disclosure. Depending on the current estate tax laws (the death tax) a trust can help preserve an estate exemption. e.g. Say the law reverts back to a $1M exemption. Note, this is $1M per deceased person, not per beneficiary. My wife and I happened to have assets of exactly $2M, and I die tomorrow. Now she has $2M, and when she passes, the estate has that $2M and estate taxes are based on this total, $1M fully taxed. But - If we set up trusts, that first million can be put into trust on my death, the interest and some principal going to the surviving spouse each year, but staying out of the survivor's estate. Second spouse dies, little or no tax due. This is known as a bypass trust. Another example is a spendthrift trust. Say, hypothetically, my sister in law can't save a nickel to save her life. Spends every dime and then some. So the best thing my mother in law can do to provide for her is to leave her estate in trust with specific instructions on how to distribute some percent each year. This is not a tax dodge of any kind, it's strictly to protect the daughter from her own irresponsibility. A medical needs trust is a variant of the above. It can provide income to a disabled person without impacting their government benefits adversely. This scratches the surface, illustrating how trusts can be used, there are more variation on this, but I believe it covers the basics. With the interest in this topic, I'm adding another issue where the trust can be useful. In my article On my Death, Please, Take a Breath I described how an inherited IRA was destroyed by ignorance. The beneficiary, fearing the stock market, withdrew it all and was nailed by taxes. He was on social security and no other income, so by taking small withdrawals each year would have had nearly no tax due. (and could have avoided 'market' risk by selling within the IRA and buying treasuries or CDs.) He didn't need a trust of course, just education. The deceased, his sister, might have used a Trust to manage the IRA and enforce limited withdrawals. Mixing IRAs and trust is complex, but the choice between a $2000 expense to create a trust or the $40K tax bill he got is pretty clear to me. He took pride in having sold out as the market soon tanked, but he could have avoided the tax loss as well. He was confusing the account (In this case an IRA, but it could have been a 401(k) or other retirement account) with the investments it contained. One can, and should, keep the IRA in tact, and simply adjust the allocation according to one's comfort level. Note - Inheritance tax laws change frequently, and my answer above was an attempt to be generic. The current (2014) code allows $5.34M to be left by one decedent with no estate tax.", "title": "" }, { "docid": "31182", "text": "A trust is a financial arrangement to put aside money over a period of time (typically years), for a specific purpose to benefit someone. Two purposes of trusts are 1) providing for retirement and 2) providing for a child or minor. There are three parties to a trust: 1) A grantor, the person who establishes and funds a trust. 2) A beneficiary, a person who receives the benefits. 3) a trustee, someone who acts in a fiduciary capacity between the grantor and beneficiary. No one person can be all three parties. A single person can be two of out those three parties. A RETIREMENT trust is something like an IRA (individual retirement account). Here, a person can be both the grantor (contributor) to the IRA, and the beneficiary (a withdrawer after retirement). But you need a bank or a broker to act as a fiduciary, and to handle the reporting to the IRS (Internal Revenue Service). Pension plans have employers as grantors, employees as beneficiaries, and (usually) a third party as trustee. A MINORS' trust can be established under a Gift to the Minors' Act, or other trust mechanisms, such as a Generation Skipping Trust. Here, a parent may be both grantor and trustee (although usually a third party is a trustee). A sum of money is put aside over a period of years for the benefit of a minor, for a college education, or for the minor's attaining a certain age: a minimum of 18, sometimes 21, possibly 25 or even older, depending on when the grantor feels that the minor is responsible enough to handle the money.", "title": "" } ]

There really is nothing to be terrified about, the extra cost to set this up was almost irrelevant in the bigger picture of legal costs around purchasing and the documents describing the ownership scheme are quite straightforward. Maybe it's a UK thing, but it seems rather commonplace here. We've chosen to hold this as \"\"tenants in common\"\" and use a trust deed for this when we purchased. We had a solicitor write the trust deed and it clearly states what percentage of the house is owned by either party and exactly what the steps would be taken, should we decide to end the trust (e.g. in case of a split-up). This includes things like the right to buy out the other person before selling on the market etc. We also had to make wills separately to indicate what should happen with our percentage of the property in case one of us died as with this type of ownership it doesn't automatically go to the other person.

How much credit you are willing to extend will vary greatly, depending on the amount and the trustworthiness of the party. For example, if you are charging $50 for something, you probably won't bother to collect money upfront, whereas if you are charging $5,000 you probably would collect some upfront. But if the party you are working for is a large financially sound company, the number may be even much higher than $5K as you can trust you will be paid. Obviously there are many factors that go into how much credit you are willing to extend to your customer. (This is why credit reports exist for banks to determine how much credit to extend to you.) As for the specific case you are asking about, which may be classified as a decent amount of work for a small business, I would default to having a written scope of work, a place in the document for both parties to sign, and specify 50% upfront payment and 50% payment at completion. When you receive the signed document and the upfront payment (and possibly even after the check clears), you begin work. I would call this my \"\"default contract\"\" and adjust according to your needs depending on the size of the job and the trustworthiness of the customer. As for your question about how to deposit the check, that depends on what type of entity you are. If you are a sole proprietor you should ask for the checks to be made out to you. If you are a business then the checks should be made out to your business name. You don't need \"\"in trust\"\" or anything similar because your customer, after paying the upfront fee, must trust that you will do the work you promise to do, just like you have to trust that after completing the work you will receive the final payment. This is the reason the default is 50% before and after. Both parties are risking (roughly) the same amount. Tip: having done the \"\"default\"\" contract many times in my career, both as a sole proprietor and a business owner, I can assure you there is a big difference between a potential customer agreeing to something in advance, and actually writing a check. The upfront payment definitely helps weed out those that were never going to end up paying you, even if their intentions were good.

But you might have trouble deducting losses on your taxes, especially if you sell to someone related to you in some way (which is indeed what you're doing). See the added portion below regarding dealing with \"\"related person\"\" (which a sibling is). The state of Maryland has a transfer/recordation tax of 1.5% for each, the buyer and seller. Would this be computed on the appraised or sale value? You should check with the State. In California property taxes are assessed based on sale value, but if the sale value is bogus the assessors have the right to recalculate. Since you're selling to family, the assessors will likely to intervene and set a more close to \"\"fair market\"\" value on the transaction, but again - check the local law. Will this pose any problem if the buyer needs financing? Likely, banks will be suspicious.Since you're giving a discount to your sibling, it will likely not cause a problem for financing. If it was an unrelated person getting such a discount, it would likely to have raised some questions. Would I be able to deduct a capital loss on my tax return? As I said - it may be a problem. If the transaction is between related people - likely not. Otherwise - not sure. Check with a professional tax adviser (EA or CPA licensed in Maryland).

A trust fiduciary and a corporation if the trust or the grantor of the trust directly or indirectly owns more than 50% in value of the outstanding stock of the corporation. A grantor and fiduciary, and the fiduciary and beneficiary, of any trust. Fiduciaries of two different trusts, and the fiduciary and beneficiary of two different trusts, if the same person is the grantor of both trusts. A tax-exempt educational or charitable organization and a person who directly or indirectly controls the organization, or a member of that person's family. A corporation and a partnership if the same persons own more than 50% in value of the outstanding stock of the corporation and more than 50% of the capital interest or profits interest in the partnership. Two S corporations if the same persons own more than 50% in value of the outstanding stock of each corporation. Two corporations, one of which is an S corporation, if the same persons own more than 50% in value of the outstanding stock of each corporation. An executor and a beneficiary of an estate unless the sale or exchange is in satisfaction of a pecuniary bequest.

A trust is a legally recognized entity that can act in business transactions much the same way as a person would (own real property, a business, insurance, investments, etc.). The short answer is the trust is the owner of the property. The trust is established by a Grantor who \"\"funds\"\" the trust by transferring ownership of items from him or herself (or itself, if another trust or business entity like a corporation) to the trust. A Trustee is appointed (usually by the Grantor) to manage the trust according to the conditions and terms specified in the trust. A Trustee would be failing in their responsibility (their fiduciary duty) if they do not act in accordance with the purposes of the trust. (Some trusts are written better than others, and there may or may not be room for broad interpretation of the purposes of the trust.) The trust is established to provide some benefit to the Beneficiary. The beneficiary can be anyone or anything, including another trust. In the US, a living trust is commonly used as an estate planning tool, where the Grantor, Trustee, and Beneficiary are the same person(s). At some point, due to health or other reasons, a new trustee can be appointed. Since the trust is a separate entity from the grantor and trustee, and it owns the assets, it can survive the death of the grantor, which makes it an attractive way to avoid having to probate the entire estate.

They use this advantage to push on other businesses, buy them up, or control them in many ways. And then they use this position to eventually take over anything that looks interesting. What you're imagining as being an open market where everyone's bonds have full information will quickly devolve into information overload, and people choosing the well known brands as their trusted source. Once that happens, the whole idea falls apart, and those few firms will find a way to control not only the money supply, but also who gets to use their money.

And mom-and-pop will quickly find themselves in a cash flow crisis, as they have tons of paper, but none of their suppliers will accept that paper. The only way to get out of this situation would be to convince IBM or GE to give Mom-and-pop some GE bonds in exchange for the John-LLC they have that nobody will accept. Of course, GE and IBM being in the enviable position as some of the few trusted money printers can refuse to accept John-LLC bonds except at a severe discount. \"\"We know John gave you John-LLC bonds to pay for his dinner worth $100, but, we'll only give you $40 worth of GE bonds for it.\"\" Mom-and-pop will quickly be fucked and go out of business due to having no \"\"hard currency\"\" (aka trusted currency) that they can use to purchase their raw materials. Demand for GE bonds will skyrocket as everyone seeks a safe-haven (a trusted currency almost everyone will accept), adn GE will find the entire market begging them to print bonds even at no interest just so that the money supply can increase to hold the full amount of trade occurring in the territory. This is then no different from the Fed during the recession a few years ago (and up until now) where they sell tons of bonds at rock-bottom interest rates simly because all the world is looking for a safe place to put their cash. The difference, of course, is that GE / IBM can take all this money and issue themselves HUGE bonuses, either on the cash directly or on the profit they've amassed by being the only trusted money issuer, whereas government officials can not.\"", "title": "" }, { "docid": "534294", "text": "> ...if we can't trust people to know what they want...

Most people don't realize that the cost to the company for a full-time employee with benefits can be 2x or even 3x the amount they see in their paycheck. Health plans are extremely expensive. Even if you are having money taken from your check for health insurance, it is often just a fraction of the total cost, and the employer is subsidizing the rest. More expensive benefits that contractors don't typically get are 401K matches and paid vacation days. When contractors call in sick or don't work because it is a national holiday, they don't get paid for that day. Also, see that line on your paycheck deducting for Social security and Medicare? That is only half of the tax. The employer pays an equal amount that is not shown on that statement. Also, they pay taxes that go towards unemployment benefits , and may be required to pay higher taxes if they churn through a lot of full-time employees. You can usually let contractors go with relative impunity . For the unemployment tax reasons, not paying for people's days off or benefits, a lot less paperwork, and less risk to the business associated with committing to full-time employees all provide value to the company. Thus companies are willing to pay more because they are getting more. Think of it like a cell phone-contract.

That doesn't mean you shouldn't invest, nor that means that you mustn't save. There are several factors at play here. First of all as a young person you are likely to have a high tolerance for risk, there is still plenty of time to recover should expected returns not materialise. Even a pension fund with the most aggressive risk / return strategy might just not quite do it for you.

Tactically I suggest saving up to build a cushion consisting of cash or near cash assets; the size of the stash should be such that it is enough to cover all of your expenses from a minimum of 2 months to a maximum of a year. The exact size will depend on your personal comfort level, whatever social net you have (parents, wife, partner) and how hard it will be to find a new source of income should the current cease to produce cash. On a strategic level you can start looking into investing any surplus cash into the foundation of what will bring joy and happiness into the next 40 years of your life.

Following @MasonWheeler's answer, if you're making that much money you should hire a bean counter to at least overlook your bookkeeping. What type of business? First, if you're the sole owner of the business you will most likely file as a sole proprietorship. If you don't have an official business entity, you should get it registered officially asap, and file under that name. The problem with sole proprietorships is liability. If you get sued, not only are your business' assets vulnerable but they can go after your personal assets too (including house/cars/etc). Legally, you and your business are considered one and the same. To avoid liability issues, you could setup a S corporation. Basically, the business is considered it's own entity and legal matters can only take as much as the business owns. You gain more protection but if you don't explicitly keep your business finances separate from your personal finances, you can get into a lot of trouble. Also, corporations generally pay out more in taxes. Technically, since the business is it's own entity you'll need to pay yourself a 'reasonable salary'. If you skip the salary and pay yourself the profits directly (ie evade being taxed on income/salary) the IRS will shut you down (that's one of the leading causes of corporations being shut down). You can also pay distribute bonuses on top of that but it would be wise to burn the words 'within reason' into your memory first. The tax man gets mad if you short him on payroll taxes. S corporations are complicated, if you go that route definitely seek help from an accountant. Bookkeeping If you're not willing to pay a full time accountant you'll need to do a lot of studying about how this works. Generally, even if you have a sole proprietorship it's best to have a separate bank account for all of your business transactions. Every source/drain of money will fall into one of 3 categories... Assets - What your business owns: Assets can be categorized by liquidity. Meaning how fast you can transform them directly into cash. Just because a company is worth a lot doesn't necessarily mean it has a lot of cash. Some assets depreciate (lose value over time) whereas some are very hard to transform back into cash based on the value and/or market fluctuations (like property). Liabilities - What you owe others and what others owe you: Everything you owe and everything that is owed to you gets tracked. Just like credit cards, it's completely possible to owe more than you own as long as you can pay the interest to maintain the loans. Equity - the net worth of the company: The approach they commonly teach in schools is called double-entry bookkeeping where they use the equation: In practice I prefer the following because it makes more sense: Basically, if you account for everything correctly both sides of the equation should match up. If you choose to go the sole proprietorship route, it's smart to track everything I've mentioned above but you can choose to keep things simple by just looking at your Equity. Equity, the heart of your business... Basically, every transaction you make having to do with your business can be simplified down to debits (money/value) increasing and credits (money/value) decreasing. For a very simple company you can assess this by looking at net profits. Which can be calculated with: Revenues, are made up of money earned by services performed and goods sold. Expenses are made up of operating costs, materials, payroll, consumables, interest on liabilities, etc. Basically, if you brought in 250K but it cost you 100K to make that happen, you've made 150K for the year in profit. So, for your taxes you can count up all the money you've made (Revenues), subtract all of the money you've paid out (Expenses) and you'll know how much profit you've made. The profit is what you pay taxes on. The kicker is, there are gray areas when it comes to deducting expenses. For instance, you can deduct the expense of using your car for business but you need to keep a log and can only expense the miles you traveled explicitly for business. Same goes for deducting dedicated workspaces in your house. Basically, do the research if you're not 100% sure about a deduction. If you don't keep detailed books and try to expense stuff without proof, you can get in trouble if the IRS comes knocking. There are always mythical stories about 'that one guy' who wrote off his boat on his taxes but in reality, you can go to jail for tax fraud if you do that. It comes down to this. At the end of the year, if your business took in a ton of money you'll owe a lot in taxes. The better you can justify your expenses, the more you can reduce that debt. One last thing. You'll also have to pay your personal federal/state taxes (including self-employment tax). That means medicare/social security, etc. If this is your first foray into self-employment you're probably not familiar with the fact that 1099 employers pick up 1/2 of the 15% medicare/social security bill. Typically, if you have an idea of what you make annually, you should be paying this out throughout the year. My pay as a contractor was always erratic so I usually paid it out once/twice a year. It's better to pay too much than too little because the gov't will give you back the money you overpaid. At the end of the day, paying taxed sucks more if you're self-employed but it balances out because you can make a lot more money. If as you said, you've broken six figures, hire a damn accountant/adviser to help you out and start reading. When people say, \"\"a business degree will help you advance in any field,\"\" it's subjects like accounting are core requirements to become a business undergrad. If you don't have time for more school and don't want to pay somebody else to take care of it, there's plenty of written material to learn it on your own. It's not rocket surgery, just basic arithmetic and a lot of business jargon (ie almost as much as technology).\"", "title": "" }, { "docid": "35810", "text": "Making a game is hard enough, focus on that. If/when you start getting close to having something to sell, then if you're serious and want the company to grow into a full time venture, briefly consult with a lawyer and possibly accountant to set this up. It will save you a lot of time researching what you have to do and a lot of headache from potentially doing things wrong. If you want to try to do it on your own, I'd recommend getting a book on starting a business because there is more to know than a single post can cover. You'll probably have to file for a DBA (doing business as) at your city hall in order to be allowed to refer to yourself as the name of your company (otherwise you have to use your personal name). Initiating that will likely initiate annual business taxes in your town in addition to the cheap filing fee. You also want to consider how you will handle trademark (of your business and game) and copyright (of your game). If this is going to grow, you'll have to have contracts written for either employees or for freelancers who might produce assets for you. You may also need to consider writing an EULA for your game, privacy policies, etc. Additionally, you'll likely have to file with your state to collect and send sales tax. You'll also want to meticulously track costs and revenue related to your business. Formally starting a business will likely open you up to property, sales and income tax. For example, where I am, was even taxed on the equipment the business uses (e.g. computers). This is why it makes sense to wait until you're closer to having a product before you try to formally start a business and to consult with professionals on the best way. The type of business you should form will depend on the scope you plan for the company and the amount of time/money you're willing to put in. A sole proprietorship (what you are by default) means there is no difference legally/financially between you as an individual and you as a company. This may be suitable if this is just a hobby, but not if you intend it to grow because that means any lawsuit directed at your company and its money is also directed at you and your money. The differences between an LLC and corporation are more nuanced and involve differences in legal and tax treatment, however, they both shield you from the previously mentioned problem.

If the MIL had the business she could deduct them as a business expense. If you have the business it would greatly complicate the taxes. Your business would be essentially covering your personal expenses. If your MIL was not a business the cost of diapers would be paid by you regardless of the working situation of you and your spouse.

Very unlikely in the next year. The debt/income ratio isn't good enough, and your credit score needs to show at least a year of regular payments without late or default issues before you can start asking for mortgages in this range. You don't mention how long you've been employed at these incomes, this can also count against you if you haven't both been employed for a full year at these incomes. They will look even more unfavorably on the employment situation if they aren't both full time jobs, although if you have a full year's worth of paychecks showing the income is regular then that might mitigate the full time/part time issue. next year or so? If you pay down your high interest debt (car, credit cards), and maintain employment (keep your check stubs and tax returns, the loan officer will want copies), then there's a slight chance. And, from this quick snap shot of our finances, does it look like we would be able to qualify for a USDA loan? Probably not. Mostly for the same reasons - the only time a USDA loan helps is when you would be able to get a regular loan if you had the down payment. Even with an available down payment of 50k, you wouldn't be able to get a regular loan, therefore it's unlikely that you'd qualify for a USDA loan. If you are anxious to get into a house, choose something much smaller, in the 100k-150k range. It would improve your debt/loan ratio enough that you might then qualify for a USDA loan. However, I think you'd still have issues if you haven't both been employed at this rate of income for at least a year, and have made regular payments on all your debts for at least a year. I'll echo what others have suggested, though, strengthen your credit, eliminate as much of your high interest debt as you can (car, credit cards), and keep your jobs for a year or two. Start a savings plan so you can contribute a small down payment - at least 3-5% of the desired home price - when you are in a better position to buy. During this time keep track of your paycheck stubs, you may need them to prove income over the time period your loan officer will request. Note that even with a USDA loan you still have to pay closing costs, and those can run several thousand dollars, so don't expect to be able to come to the table with no cash. Lastly, there's good reason to be very conservative regarding house cost and size. If you can, consider buying the house as if you only had the 46k per year. Move the debt to the person making the lower income, and if you buy the house in the name of the person only making 46k per year, then the debt/loan ratio looks very positive. Further it may be that the credit history of that person is better, and the employment history is better. If one of you has better history in these ways, then you might have a better chance if only one of you buys the house. Banks can't tell you about this, but it does work. Keep in mind, though, that if you two part ways it could be very unhappy since one would be left with all the debt and the house would be in the other's name.

When it comes to taxes, you will file a 1040 (the big one, not a 1040EZ nor 1040A). In addition you will file a schedule C (self-employed income), where you will report the gross paid to you, deduct your expenses, and come up with your profit, which will be taxable.

I hand my tax declaration to my \"\"home\"\" tax office (where also my freelancing adress is), even though my day-job is 300 km away. So if you work mostly from Poland and just visit the German customer a few times, you are fine anyways. Difficulties start if you move to Germany to do the work at your customer's place.

Close by the link you provided is a kind of FAQ on this EU regulation About the question of permanent vs. temporary they say: The temporary nature of the service is assessed on a case-by-case basis. Here's my German-Italian experience with this. Background: I had a work contract plus contracts for services and I moved for a while to Italy. Taxes and social insurance on the Italian contracts had to be paid to Italy. Including tax on the contract for services. Due to the German-Italian tax treaty, there is no double taxation. Same for Poland: this is part of EU contracts. By the way: The temporary time frame for Italy seemed to be 3 months, then I had to provide an Italian residence etc. and was registered in the Italian health care etc. system.

Scheinselbständigkeit means contracts that claim to be service contracts with a self-employed provider who is doing the work in a way that is typical for employees. This law closes a loophole so employer + employee cannot avoid paying income tax and social insurance fees (pension contributions and unemployment insurance on both sides - health insurance would have to be paid in full by the self-employed instead of partially by the employer. Employer also avoids accident insurance, and several regulations from labour law are avoided as well).

A single market maker usually covers many stocks, and a single stock is usually covered by many market makers. The NYSE has \"\"specialists\"\" that are market makers that also performed a few other roles in the management of trading for a stock, and usually a single issue on the NYSE is covered by only one market maker. Market makers are often middlemen between brokers (ignoring stuff like dark pools, and the fact that brokers will often trade stocks internally among their own clients before going to the exchange). Historically, the market makers gave up buy/sell discretion in exchange for being the \"\"go-to guys\"\" for anyone wanting to trade in that stock. When you told your broker to buy a stock for you, he didn't hook you up with another retail investor; he went to the market maker. Market makers would also sometimes find investors willing to step in when more liquidity was needed for a security. They were like other floor traders; they hung out on the exchange floors and interacted with traders to buy and sell stocks. Traders came to them when they wanted to buy one of the specialist's issues. There was no public order book; just ticker tape and a quote. It was up to the market maker to maintain that order book. Since they are effectively forbidden from being one-sided traders in a security, their profit comes from the bid-ask spread. Being the counter-party to almost every trade, they'd make profit from always selling above where they were buying. (Except when the price moved quickly -- the downside to this arrangement.) \"\"The spread goes to the market maker\"\" is just stating that the profit implicit in the spread gets consumed by the market maker. With the switch to ECNs, the role of the market maker has changed. For example, ForEx trading firms tend to act as market makers to their customers. On ECNs, the invisible, anonymous guy at the other end of most trades is often a market maker, still performing his traditional role. Yet brokers can interact directly with each other now, rather than relying on the market maker's book. With modern online investing and public order books, retail investors might even be trading directly with each other. Market makers are still out there; in part, they perform a service sold by an Exchange to the companies that choose to be listed on that exchange.

Black pools are trades done where the price is not shared with the market. But the DTC is the one who keeps track of who owns which shares. They have records of all net transactions2. The DTC is the counterparty for transactions. When stock moves from one entity to another the DTC is involved. As the central counterparty for the nation's major exchanges and markets, DTCC clears and settles virtually all broker-to-broker equity 1. This is the link that shows that settlements are reported on a \"\"net basis\"\". 2. If broker A sells 1000 shares of something to broker B at 8 and then five minutes later broker B sells the 1000 shares back to A, you cannot be sure that that total volume will be recorded. No net trading took place and there would be fees to pay for no reason if they reported both trades. Note: In dark pool trading quite often the two parties don't know each other.

On ETNs, they often (always?) settle in cash. As an example of an option I'm currently looking at, AVSPY, it settles in cash (please confirm by reading the documentation on this set of options at http://www.nasdaqomxtrader.com/Micro.aspx?id=Alpha, but it is an example of this). There's nothing it can settle into (as you can't purchase the AVSPY index, only options on it). You may quickly look (wikipedia) at the difference between \"\"American Style\"\" options and \"\"European Style\"\" options, for more understanding here. Interestingly I just spoke to my broker about this subject for a trade execution. Before I go into that, let me also quickly refer to Joe's answer: what you buy, you can sell. That's one of the jobs of a market maker, to provide liquidity in a market. So, when you buy a stock, you can sell it. When you buy an option, you can sell it. That's at any time before expiration (although how close you do it before the closing bell on expiration Friday/Saturday is your discretion). When a market maker lists an option price, they list a bid and an ask. If you are willing to sell at the bid price, they need to purchase it (generally speaking). That's why they put a spread between the bid and ask price, but that's another topic not related to your question -- just note the point of them buying at the bid price, and selling at the ask price -- that's what they're saying they'll do. Now, one major difference with options vs. stocks is that options are contracts. So, therefore, we can note just as easily that YOU can sell the option on something (particularly if you own either the underlying, or an option deeper in the money). If you own the underlying instrument/stock, and you sell a CALL option on it, this is a strategy typically referred to as a covered call, considered a \"\"risk reduction\"\" strategy. You forfeit (potential) gains on the upside, for money you receive in selling the option. The point of this discussion is, is simply: what one buys one can sell; what one sells one can buy -- that's how a \"\"market\"\" is supposed to work. And also, not to think that making money in options is buying first, then selling. It may be selling, and either buying back or ideally that option expiring worthless. -- Now, a final example. Let's say you buy a deep in the money call on a stock trading at $150, and you own the $100 calls. At expiration, these have a value of $50. But let's say, you don't have any money in your account, to take ownership of the underlying security (you have to come up with the additional $100 per share you are missing). In that case, need to call your broker and see how they handle it, and it will depend on the type of account you have (e.g. margin or not, IRA, etc). Generally speaking though, the \"\"margin department\"\" makes these decisions, and they look through folks that have options on things that have value, and are expiring, and whether they have the funds in their account to absorb the security they are going to need to own. Exchange-wise, options that have value at expiration, are exercised. But what if the person who has the option, doesn't have the funds to own the whole stock? Well, ideally on Monday they'll buy all the shares with the options you have at the current price, and immediately liquidate the amount you can't afford to own, but they don't have to.

Almost any company can go bankrupt. One small note: a company goes bankrupt, not its stock. Its stock may become worthless in bankruptcy, but a stock disappearing or being delisted doesn't necessarily mean the company went bankrupt. Bankruptcy has implications for a company's debt as well, so it applies to more than just its stock. I don't know of any historical instances where this has happened, but presumably, the warning signs of bankruptcy would be evident enough that a few things could happen. Another company, e.g. another exchange, holding firm, etc. could buy out the exchange that's facing financial difficulty, and the companies traded on it would transfer to the new company that's formed. If another exchange bought out the struggling exchange, the shares of the latter could transfer to the former. This is an attractive option because exchanges possess a great deal of infrastructure already in place. Depending on the country, this could face regulatory scrutiny however. Other firms or governments could bail out the exchange if no one presented a buyout offer. The likelihood of this occurring depends on several factors, e.g. political will, the government(s) in question, etc. For a smaller exchange, the exchange could close all open positions at a set price. This is exactly what happened with the Hong Kong Mercantile Exchange (HKMex) that MSalters mentioned. When the exchange collapsed in May 2013, it closed all open positions for their price on the Thursday before the shutdown date. I don't know if a stock exchange would simply close all open positions at a set price, since equity technically exists in perpetuity regardless of the shutdown of an exchange, while many derivatives have an expiration date. Furthermore, this might not be a feasible option for a large exchange. For example, the Chicago Mercantile Exchange lists thousands of products and manages hundreds of millions of transactions, so closing all open positions could be a significant undertaking. If none of the above options were available, I presume companies listed on the exchange would actively move to other, more financially stable exchanges. These companies wouldn't simply go bankrupt. Contracts can always be listed on other exchanges as well. Considering the high level of mergers and acquisitions, both unsuccessful and successful, in the market for exchanges in recent years, I would assume that option 1 would be the most likely (see the NYSE Euronext/Deutsche Börse merger talks and the NYSE Euronext/ICE merger that's currently in progress), but for smaller exchanges, there is the recent historical precedent of the HKMex that speaks to #3. Also, the above answer really only applies to publicly traded stock exchanges, and not all stock exchanges are publicly-held entities. For example, the Shanghai Stock Exchange is a quasi-governmental organization, so I presume option 2 would apply because it already receives government backing. Its bankruptcy would mean something occurred for the government to withdraw its backing or that it became public, and a discussion of those events occurring in the future is pure speculation.", "title": "" }, { "docid": "14781", "text": "\"Yes, you're still exposed to currency risk when you purchase the stock on company B's exchange. I'm assuming you're buying the shares on B's stock exchange through an ADR, GDR, or similar instrument. The risk occurs as a result of the process through which the ADR is created. In its simplest form, the process works like this: I'll illustrate this with an example. I've separated the conversion rate into the exchange rate and a generic \"\"ADR conversion rate\"\" which includes all other factors the bank takes into account when deciding how many ADR shares to sell. The fact that the units line up is a nice check to make sure the calculation is logically correct. My example starts with these assumptions: I made up the generic ADR conversion rate; it will remain constant throughout this example. This is the simplified version of the calculation of the ADR share price from the European share price: Let's assume that the euro appreciates against the US dollar, and is now worth 1.4 USD (this is a major appreciation, but it makes a good example): The currency appreciation alone raised the share price of the ADR, even though the price of the share on the European exchange was unchanged. Now let's look at what happens if the euro appreciates further to 1.5 USD/EUR, but the company's share price on the European exchange falls: Even though the euro appreciated, the decline in the share price on the European exchange offset the currency risk in this case, leaving the ADR's share price on the US exchange unchanged. Finally, what happens if the euro experiences a major depreciation and the company's share price decreases significantly in the European market? This is a realistic situation that has occurred several times during the European sovereign debt crisis. Assuming this occurred immediately after the first example, European shareholders in the company experienced a (43.50 - 50) / 50 = -13% return, but American holders of the ADR experienced a (15.95 - 21.5093) / 21.5093 = -25.9% return. The currency shock was the primary cause of this magnified loss. Another point to keep in mind is that the foreign company itself may be exposed to currency risk if it conducts a lot of business in market with different currencies. Ideally the company has hedged against this, but if you invest in a foreign company through an ADR (or a GDR or another similar instrument), you may take on whatever risk the company hasn't hedged in addition to the currency risk that's present in the ADR/GDR conversion process. Here are a few articles that discuss currency risk specifically in the context of ADR's: (1), (2). Nestle, a Swiss company that is traded on US exchanges through an ADR, even addresses this issue in their FAQ for investors.

That's a popular use of puts. But I think the wording of your question is angling for another strategy: Writing puts. Consider: Cart's strategy refers to the buyer of a put. But, on the transaction's other side is a seller of the put – and ultimately somebody created or wrote that put contract in the first place! That first seller of the put – that is, the seller that isn't just selling one they themselves bought – is the put writer. When you write a put, you are taking on the obligation to buy the other side's stock at the put exercise price if the stock price falls below that exercise price by the expiry date. For taking on the obligation, you receive a premium, like how an insurance company charges a premium to insure against a loss. Example: Imagine ABC Co. stock is trading at $25.00. You write a put contract agreeing to buy 100 shares of ABC at $20.00 per share (the exercise price) by a given expiration date. Say you receive $2.00/share premium from the put buyer. You now have the obligation to purchase the shares from the put buyer in the event they are below $20.00 per share when the option expires – or, technically any time before then, if the buyer chooses to exercise the option early. Assuming no early assignment, one of two things will happen at the option expiration date: ABC trades at or above $20.00 per share. In this case, the put option will expire worthless in the hands of the put buyer. You will have pocketed the $200 and be absolved from your obligation. This case, where ABC trades above the exercise price, is the maximum profit potential. ABC trades below $20.00 per share. In this case, the put option will be assigned and you'll need to fork over $2000 to the put buyer in exchange for his 100 ABC shares. If those shares are worth less than $18.00 in the market, then you've suffered a loss to the extent they are below that price (times 100), because remember – you pocketed $200 premium in the first place. If the shares are between $18.00 to $20.00, you're still profitable, but not to the full extent of the premium received. You can see that by having written a put it's possible to acquire ABC stock at a price lower than the market price – because you received some premium in the process of writing your put. If you don't \"\"succeed\"\" in acquiring shares on your first write (because the shares didn't get below the exercise price), you can continue to write puts and collect premium until you do get assigned. I have read the book \"\"Money for Nothing (And Your Stocks for FREE!)\"\" by Canadian author Derek Foster. Despite the flashy title, the book essentially describes Derek's strategy for writing puts against dividend-paying value stocks he would love to own. Derek picks quality companies that pay a dividend, and uses put writing to get in at lower-than-market prices. Four Pillars reviewed the book and interviewed Derek Foster: Money for Nothing: Book Review and Interview with Derek Foster. Writing puts entails risk. If the stock price drops to zero then you'll end up paying the put exercise price to acquire worthless shares! So your down-side can easily be multiples of the premium collected. Don't do this until and unless you understand exactly how this works. It's advanced. Note also that your broker isn't likely to permit you to write puts without having sufficient cash or margin in your account to cover the case where you are forced to buy the stock. You're better off having cash to secure your put buys, otherwise you may be forced into leverage (borrowing) when assigned.

Before electronic trading and HFTs specifically, trading was thin and onerous. Today, the average investor can open up a web page, type in a security, and buy at the narrowest spread permitted by regulators with anyone else who wants to take the other side. Before the lines between market maker and speculator became blurred to indistinction, a market maker was one who was contractually obligated to an exchange to provide a bid and ask for a given security on said exchange even though at heart a market maker is still simply a trader despite the obligation. A market maker would simultaneously buy a large amount of securities privately and short the same amount to have no directional bias, exposure to the direction of the security, and commence to making the market. The market maker would estimate its cost basis for the security based upon those initial trades and provide a bid and ask appropriate for the given level of volume. If volumes were high, the spread would be low and vice versa. Market makers who survived crashes and spikes would forgo the potential profit in always providing a steady price and spread, ie increased volume otherwise known as revenue, to maintain no directional bias. In other words, if there were suddenly many buyers and no sellers, hitting the market maker's ask, the MM would raise the ask rapidly in proportion to the increased exposure while leaving the bid somewhere below the cost basis. Eventually, a seller would arise and hit the MM's bid, bringing the market maker's inventory back into balance, and narrowing the spread that particular MM could provide since a responsible MM's ask could rise very high very quickly if a lack of its volume relative to its inventory made inventory too costly. This was temporarily extremely costly to the trader if there were few market makers on the security the trader was trading or already exposed to. Market makers prefer to profit from the spread, bidding below some predetermined price, based upon the cost basis of the market maker's inventory, while asking above that same predetermined cost basis. Traders profit from taking exposure to a security's direction or lack thereof in the case of some options traders. Because of electronic trading, liquidity rebates offered by exchanges not only to contractually obligated official market makers but also to any trader who posts a limit order that another trader hits, and algorithms that become better by the day, market making HFTs have supplanted the traditional market maker, and there are many HFTs where there previously were few official market makers. This speed and diversification of risk across many many algorithmically market making HFTs have kept spreads to the minimum on large equities and have reduced the same for the smallest equities on major exchanges. Orders and quotes are essentially identical. Both are double sided auction markets with impermenant bids and asks. The difference lies in that non-market makers, specialists, etc. orders are not shown to the rest of the market, providing an informational advantage to MMs and an informational disadvantage to the trader. Before electronic trading, this construct was of no consequence since trader orders were infrequent. With the prevalence of HFTs, the informational disadvantage has become more costly, so order driven markets now prevail with much lower spreads and accelerated volumes even though market share for the major exchanges has dropped rapidly and hyperaccelerated number of trades even though the size of individual trades have fallen. The worst aspect of the quote driven market was that traders could not directly trade with each other, so all trades had to go between a market maker, specialist, etc. While this may seem to have increased cost to a trader who could only trade with another trader by being arbitraged by a MM et al, paying more than what another trader was willing to sell, these costs were dwarfed by the potential absence of those market makers. Without a bid or ask at any given time, there could be no trade, so the costs were momentarily infinite. In essence, a quote driven market protects market makers from the competition of traders. While necessary in the days where paper receipts were carted from brokerage to brokerage, and the trader did not dedicate itself to round the clock trading, it has no place in a computerized market.

If you own a stock you are shorting, the IRS could view the transaction as a Sell followed by a buy taking place in a less than 30 day period and you could be subject to wash-sale rules. This added complexity (most often the finding of someone to loan you the security you are shorting) is another reason such trades are considered more advanced. You should also be aware that there are currently a number of proposals to re-instate the 'uptick rule' or some circuit-breaker variant. Designed to prevent short-sellers from driving down the price of a stock (and conducting 'bear raids etc) the first requires that a stock trade at the same or higher price as prior trades before you can submit a short.

The Wikipedia article on inverse ETF's lists a number of other such funds covering various markets.

Clathrin stabilizes the spindle fiber apparatus during mitosis.
[ { "docid": "2033917", "text": "Clathrin has an established function in the generation of vesicles that transfer membrane and proteins around the cell. The formation of clathrin-coated vesicles occurs continuously in non-dividing cells, but is shut down during mitosis, when clathrin concentrates at the spindle apparatus. Here, we show that clathrin stabilizes fibres of the mitotic spindle to aid congression of chromosomes. Clathrin bound to the spindle directly by the amino-terminal domain of clathrin heavy chain. Depletion of clathrin heavy chain using RNA interference prolonged mitosis; kinetochore fibres were destabilized, leading to defective congression of chromosomes to the metaphase plate and persistent activation of the spindle checkpoint. Normal mitosis was rescued by clathrin triskelia but not the N-terminal domain of clathrin heavy chain, indicating that stabilization of kinetochore fibres was dependent on the unique structure of clathrin. The importance of clathrin for normal mitosis may be relevant to understanding human cancers that involve gene fusions of clathrin heavy chain.", "title": "Clathrin is required for the function of the mitotic spindle" } ]

How the spindle factors direct and attach MTs to the chromosomes are key open questions.

Several NLS proteins have been identified as spindle assembly factors, but the complexity of the process led us to search for additional proteins with distinct roles in spindle assembly. RESULTS We identify a chromatin-remodeling ATPase, CHD4, as a RanGTP-dependent microtubule (MT)-associated protein (MAP). MT binding occurs via the region containing an NLS and chromatin-binding domains. In Xenopus egg extracts and cultured cells, CHD4 largely dissociates from mitotic chromosomes and partially localizes to the spindle. Immunodepletion of CHD4 from egg extracts significantly reduces the quantity of MTs produced around chromatin and prevents spindle assembly. CHD4 RNAi in both HeLa and Drosophila S2 cells induces defects in spindle assembly and chromosome alignment in early mitosis, leading to chromosome missegregation. Further analysis in egg extracts and in HeLa cells reveals that CHD4 is a RanGTP-dependent MT stabilizer. Moreover, the CHD4-containing NuRD complex promotes organization of MTs into bipolar spindles in egg extracts. Importantly, this function of CHD4 is independent of chromatin remodeling.

However, the mechanism underlying this polyploidization remains totally unknown. It has been postulated that polyploidization is due to a skipping of mitosis after each round of DNA replication. We carried out immunohistochemical studies on mouse bone marrow megakaryocytes during thrombopoietin- induced polyploidization and found that during this process megakaryocytes indeed enter mitosis and progress through normal prophase, prometaphase, metaphase, and up to anaphase A, but not to anaphase B, telophase, or cytokinesis. It was clearly observed that multiple spindle poles were formed as the polyploid megakaryocytes entered mitosis; the nuclear membrane broke down during prophase; the sister chromatids were aligned on a multifaced plate, and the centrosomes were symmetrically located on either side of each face of the plate at metaphase; and a set of sister chromatids moved into the multiple centrosomes during anaphase A. We further noted that the pair of spindle poles in anaphase were located in close proximity to each other, probably because of the lack of outward movement of spindle poles during anaphase B. Thus, the reassembling nuclear envelope may enclose all the sister chromatids in a single nucleus at anaphase and then skip telophase and cytokinesis. These observations clearly indicate that polyploidization of megakaryocytes is not simply due to a skipping of mitosis, and that the megakaryocytes must have a unique regulatory mechanism in anaphase, e.g., factors regulating anaphase such as microtubule motor proteins might be involved in this polyploidization process.", "title": "Thrombopoietin-induced Polyploidization of Bone Marrow Megakaryocytes Is Due to a Unique Regulatory Mechanism in Late Mitosis " }, { "docid": "4398832", "text": "The most conspicuous event in the cell cycle is the alignment of chromosomes in metaphase. Chromosome alignment fosters faithful segregation through the formation of bi-oriented attachments of kinetochores to spindle microtubules.

How robust error correction is achieved in prometaphase to ensure error-free mitosis remains unknown. Here we show that k-MT attachments in prometaphase cells are considerably less stable than in metaphase cells. The switch to more stable k-MT attachments in metaphase requires the proteasome-dependent destruction of cyclin A in prometaphase. Persistent cyclin A expression prevents k-MT stabilization even in cells with aligned chromosomes. By contrast, k-MTs are prematurely stabilized in cyclin-A-deficient cells. Consequently, cells lacking cyclin A display higher rates of chromosome mis-segregation.

These proteins are localized by the chromosomal passenger complex, which regulates the loss of meiotic chromosome cohesion. Thus, meiotic segregation in C. elegans is a two-stage process, where kinetochores orient chromosomes, but are then dispensable for their separation.

Thus, we find that alteration of polymerase beta expression appears to induce major genetic changes associated with a malignant phenotype.", "title": "Deregulated DNA polymerase beta induces chromosome instability and tumorigenesis." }, { "docid": "15926408", "text": "A major challenge each human cell-division cycle is to ensure that DNA replication origins do not initiate more than once, a phenomenon known as re-replication. Acute deregulation of replication control ultimately causes extensive DNA damage, cell-cycle checkpoint activation and cell death whereas moderate deregulation promotes genome instability and tumorigenesis. In the absence of detectable increases in cellular DNA content however, it has been difficult to directly demonstrate re-replication or to determine if the ability to re-replicate is restricted to a particular cell-cycle phase. Using an adaptation of DNA fiber spreading we report the direct detection of re-replication on single DNA molecules from human chromosomes. Using this method we demonstrate substantial re-replication within 1 h of S phase entry in cells overproducing the replication factor, Cdt1. Moreover, a comparison of the HeLa cancer cell line to untransformed fibroblasts suggests that HeLa cells produce replication signals consistent with low-level re-replication in otherwise unperturbed cell cycles. Re-replication after depletion of the Cdt1 inhibitor, geminin, in an untransformed fibroblast cell line is undetectable by standard assays but readily quantifiable by DNA fiber spreading analysis. Direct evaluation of re-replicated DNA molecules will promote increased understanding of events that promote or perturb genome stability.", "title": "Analysis of re-replication from deregulated origin licensing by DNA fiber spreading" }, { "docid": "10704438", "text": "Cells are equipped with a cell-intrinsic signaling network called the DNA damage response (DDR). This signaling network recognizes DNA lesions and initiates various downstream pathways to coordinate a cell cycle arrest with the repair of the damaged DNA. Alternatively, the DDR can mediate clearance of affected cells that are beyond repair through apoptosis or senescence. The DDR can be activated in response to DNA damage throughout the cell cycle, although the extent of DDR signaling is different in each cell cycle phase. Especially in response to DNA double strand breaks, only a very marginal response was observed during mitosis. Early on it was recognized that cells which are irradiated during mitosis continued division without repairing broken chromosomes. Although these initial observations indicated diminished DNA repair and lack of an acute DNA damage-induced cell cycle arrest, insight into the mechanistic re-wiring of DDR signaling during mitosis was only recently provided. Different mechanisms appear to be at play to inactivate specific signaling axes of the DDR network in mitosis. Importantly, mitotic cells not simply inactivate the entire DDR, but appear to mark their DNA damage for repair after mitotic exit. Since the treatment of cancer frequently involves agents that induce DNA damage as well as agents that block mitotic progression, it is clinically relevant to obtain a better understanding of how cancer cells deal with DNA damage during interphase versus mitosis.

We demonstrate here that de novo centromere assembly on HAC/MAC is dependent on CENP-B. In contrast, centromere formation is suppressed in cells expressing CENP-B when alpha-satellite DNA was integrated into a chromosomal site. Remarkably, on those integration sites CENP-B enhances histone H3-K9 trimethylation and DNA methylation, thereby stimulating heterochromatin formation. Thus, we propose that CENP-B plays a dual role in centromere formation, ensuring de novo formation on DNA lacking a functional centromere but preventing the formation of excess centromeres on chromosomes.", "title": "CENP-B Controls Centromere Formation Depending on the Chromatin Context" } ]

A credit card authorization is basically the merchant asking your credit card company \"\"Does sandi have enough credit to pay this amount and if so please reserve that amount for a bit.\"\" The authorization will decrease the total credit you have available on the card, but it's not actually a charge, so if your billing cycle ends, it won't show up on your statement.

Even if your credit card company doesn't show pending transactions, you'll see a decrease in your available credit, however you shouldn't see an increase in your balance. The next step, and the only way the original merchant gets paid, is for the merchant to actually post a transaction to your card. Then it becomes a real charge that will show up on your next credit card statement and you'll be expected to pay it (unless you dispute the charge, but that's a different issue).

The merchant then cancelled the authorization (going by the start of your third paragraph). So there was never an actual transaction posted, you were never charged, and you never really owed any money.

It will require you filling out a form with the old 401k provider and they’ll transfer the balance of your account directly to the new 401k. 2) Rollover the old 401k to a Traditional IRA. This involves opening a new traditional IRA if you don’t already have one (I assume you don’t). Vanguard is a reddit favorite and I can vouch for them as Well.

So, the money you withdraw from your Roth IRA will not be taxed entirely as ordinary income. In fact, you are allowed to withdraw the amount of your original contributions (also known as basis) without any taxes or penalties. Let's imagine you originally deposited $9000 of that current $10K total value – then in such a case, $9000 could be withdrawn tax and penalty free. The bad news: When it comes to the investment earnings – the other $1000 in my example – it's a different story: Since you wouldn't be age 59 1/2 at the time of withdrawal, any money taken out beyond your original contributions would be considered a non-qualified withdrawal and subject to both ordinary income taxes plus a 10% early withdrawal penalty.

However, compared to things like savings accounts and bonds, where you get taxed on the interest yearly, it is much better. Every time you get taxed on gains like this, it is taxing gains earned from after-tax money, so if you think of an amount of money as being equivalent to the amount of money it grows to over time (time value of money), then it is taxing money that is (or grown from money that is) already taxed.

IRA distributions are taxed, in their entirety, as ordinary income. If you withdraw before the retirement age, additional 10% penalty is added. Investment income has preferential treatment - long term capital gains and qualified dividends are taxed at lower rates than ordinary income. However, IRA contributions are tax deductible. I.e.: you don't pay taxes on the amounts contributed to the IRA when you earned the money, only when you withdraw. In the mean time, the money is growing, tax free, based on your investments. Anything inside the IRA is tax free, including dividends, distributions (from funds to your IRA, not from IRA to you), capital gains, etc. This is very powerful, when taking into account the compounding effect of reinvesting your dividends/sale proceeds without taking a chunk out for taxes. Consider you make an investment in a fund that appreciated 100% in half a year. You cash out to reinvest in something less volatile to lock the gains. In a regular account - you pay taxes when you sell, based on your brackets. In the IRA you reinvest all of your sale proceeds. That would be ~25-35% more of the gains to reinvest and continue working for you! However, if you decide to withdraw - you pay ordinary rate taxes on the whole amount. If you would invest in a single fund for 30 years in a regular account - you'd pay 20% capital gains tax (on the appreciation, not the dividends). In the IRA, if you invest in the same fund for the same period - you'll pay your ordinary income rates. However, the benefit of reinvesting dividends tax-free softens the blow somewhat, but that's much harder to quantify. Bottom line: if you want to plan for retirement - plan for retirment. Otherwise - IRA is not an investment vehicle. Also consider Roth IRA/conversions. Roth IRA has the benefit of tax free distributions at retirement. If your current tax bracket is at 20%, for example, contributing $5K to Roth IRA instead of a traditional will cost you $1K of taxes now, but will save you all the taxes during the retirement (for the distributions from the Roth IRA).

I suggest keeping Roth amounts for this purpose as they're easily accessible and bear no taxable consequence. Other than emergencies don't touch them for as long as you can.

Traditional versus Roth comparison calculator. Here are a bunch more IRA and 401k calculators. Take a look at the IRA tax savings for various amounts compared to the same money in a taxable account. Compounding over time will make you rich and there's your reason for starting young. Increases in the value of gold and silver will never touch compounded gains. So tax savings are a huge reason to stash your money in an IRA. You trade liquidity (having to wait until age 59.5) for a heck of a lot more money. Though isn't it nice to be assured that you will have money when you retire? If you aren't going to earn it then, you'll have to earn it now. If you are going to earn it now, you may as well put it in a place that earns you even more. A traditional IRA has penalties for withdrawing before retirement age. With a Roth you can withdraw the principal at anytime without penalty as long as the account has been open 5 years. A traditional IRA requires you take out a certain amount once you reach retirement. A Roth doesn't, which means you can leave money in the account to grow even more. A Roth can be passed on to a spouse after death, and after the spouse's death onto another beneficiary. more on IRA Required Minimum Distributions.\"", "title": "" }, { "docid": "94496", "text": "First of all, there are some differences between the retirement accounts that you mentioned regarding taxes. Traditional IRA and 401(k) accounts allow you to make pre-tax contributions, giving you an immediate tax deduction when you contribute. Roth IRA, Roth 401(k) are funded with after tax money, and a non-retirement account is, of course, also funded with after tax money. So if you are looking for the immediate tax deduction, this is a point in favor of the retirement accounts. Roth IRA & Roth 401(k) accounts allow the investment to grow tax-free, which means that the growth is not taxed, even when taking the investment out at retirement. With Traditional IRA and 401(k) accounts, you need to pay tax on the gains realized in the account when you withdraw the money, just as you do with a non-retirement account. This is a point in favor of the Roth retirement accounts. To answer your question about capital gains, yes, it is true that you do not have a capital gain until an investment is sold. So, discounting the contribution tax deductions of the retirement accounts, if you only bought individual stocks that never paid a dividend, and never sold them until retirement, you are correct that it really wouldn't matter if you had it in a regular brokerage account or in a traditional IRA. However, even people dedicated to buy-and-hold rarely actually buy only individual stocks and hold them for 30 years. There are several different circumstances that will generally happen in the time between now and when you want to withdraw the money in retirement that would be taxable events if you are not in a retirement account: If you sell an investment and buy a different one, the gains would be taxable. If you want to rebalance your holdings, this also involves selling a portion of your investments. For example, if you want to maintain an 80% stock/20% bond ratio, and your stock values have gone up to 90%, you might want to sell some stock and buy bonds. Or if you are getting closer to retirement, you might decide to go with a higher percentage of bonds. This would trigger capital gains. Inside a mutual fund, anytime the management sells investments inside the fund and realizes capital gains, these gains are passed on to the investors, and are taxable. (This happens more often with managed funds than index funds, but still happens occasionally with index funds.) Dividends earned by the investments are taxable. Any of these events in a non-retirement account would trigger taxes that need to be paid immediately, even if you don't withdraw a cent from your account.", "title": "" }, { "docid": "508219", "text": "\"Basically, the idea of an IRA is that the money is earned by you and would normally be taxed at the individual rate, but the government is allowing you to avoid paying the taxes on it now by instead putting it in the account. This \"\"tax deferral\"\" encourages retirement savings by reducing your current taxable income (providing a short-term \"\"carrot\"\"). However, the government will want their cut; specifically, when you begin withdrawing from that account, the principal which wasn't taxed when you put it in will be taxed at the current individual rate when you take it out. When you think about it, that's only fair; you didn't pay taxes on it when it came out of your paycheck, so you should pay that tax once you're withdrawing it to live on. Here's the rub; the interest is also taxed at the individual rate. At the time, that was a good thing; the capital gains rate in 1976 (when the Regular IRA was established) was 35%, the highest it's ever been. Now, that's not looking so good because the current cap gains rate is only 15%. However, these rates rise and fall, cap gains more than individual rates, and so by contributing to a Traditional IRA you simplify your tax bill; the principal and interest is taxed at the individual rate as if you were still making a paycheck. A Roth IRA is basically the government trying to get money now by giving up money later. You pay the marginal individual rate on the contributions as you earn them (it becomes a \"\"post-tax deduction\"\") but then that money is completely yours, and the kicker is that the government won't tax the interest on it if you don't withdraw it before retirement age. This makes Roths very attractive to retirement investors as a hedge against higher overall tax rates later in life. If you think that, for any reason, you'll be paying more taxes in 30 years than you would be paying for the same money now, you should be investing in a Roth. A normal (non-IRA) investment account, at first, seems to be the worst of both worlds; you pay individual tax on all earned wages that you invest, then capital gains on the money your investment earns (stock gains and dividends, bond interest, etc) whenever you cash out. However, a traditional account has the most flexibility; you can keep your money in and take your money out on a timeline you choose. This means you can react both to market moves AND to tax changes; when a conservative administration slashes tax rates on capital gains, you can cash out, pay that low rate on the money you made from your account, and then the money's yours to spend or to reinvest. You can, if you're market- and tax-savvy, use all three of these instruments to your overall advantage. When tax rates are high now, contribute to a traditional IRA, and then withdraw the money during your retirement in times where individual tax rates are low. When tax rates are low (like right now), max out your Roth contributions, and use that money after retirement when tax rates are high. Use a regular investment account as an overage to Roth contributions when taxes are low; contribute when the individual rate is low, then capitalize and reinvest during times when capital gains taxes are low (perhaps replacing a paycheck deduction in annual contributions to a Roth, or you can simply fold it back into the investment account). This isn't as good as a Roth but is better than a Traditional; by capitalizing at an advantageous time, you turn interest earned into principal invested and pay a low tax on it at that time to avoid a higher tax later. However, the market and the tax structure have to coincide to make ordinary investing pay off; you may have bought in in the early 90s, taking advantage of the lowest individual rates since the Great Depression. While now, capital gains taxes are the lowest they've ever been, if you cash out you may not be realizing much of a gain in the first place.\"", "title": "" }, { "docid": "298108", "text": "\"If you have maxed out your IRA contribution for 2017 already (and it all went into your Roth IRA), then, until the 2017 Tax Day in April 2018, you can remove any part of this contribution (and the earnings therefrom) from your Roth IRA without any tax consequences or penalties. If you discover in early 2018 that you are not eligible (or only partially eligible) to contribute to a Roth IRA, then of course you must remove all (or part) of your 2017 contributions (and the earnings therefrom) from your Roth IRA by the 2017 Tax Day in April 2018.

You won't be able to withdraw this money until 59 1/2 years of age without paying a penalty, the same goes for your current 401k.

Also money in and IRA does not have to be invested it could be in a liquid position. Now a pre tax retirement account doesn't have the same luxury. If I stick 5k into a traditional IRA and it grows to 7k and I pull that money out the entire ammount gets taxed AND penalized (even the principal amount is subject the 10% penalty). Now if you do a Roth conversion (pre-tax to post-tax retirment account conversion) the principal ammount (the amount you paid taxes on) is still subject to the 10% penalty for 5 years.

Your income is probably in the 25% bracket now. It's hard to say whether that should be considered \"\"high\"\" or \"\"low\"\". Some people advocate Roth only for 15% bracket; but your income would probably go into higher brackets in the future, so Roth may be preferable from this point of view. Roth IRA also has another advantage that the principal of contributions can be taken out at any time without tax or penalty, so it can serve as an emergency fund just as well as money in taxable accounts. Given that you may not have a lot of money saved up right now, this is useful. 2) In a sense, it's nice to have a mix of Traditional and Roth when you withdraw to hedge against uncertainty in future tax rates and have the option of choosing whichever one is advantageous to withdraw when you need to withdraw. That said, you will likely have many years of access to a 401k and high income in your future working years, in which you can contribute to a Traditional 401k (or if no access to 401k, then Traditional IRA), so a mix will almost certainly happen even if you go all Roth IRA now. 3) I think that depends on you, whether you are a hands-on or hands-off kind of investor.\"", "title": "" }, { "docid": "92442", "text": "Is there any benefit to investing in a Roth 401(k) plan, as opposed to a Roth IRA? They have separate contribution limits, so how much you contribute to one does not change the amount you can contribute to the other. Which is relevant to your question because you said the earnings on that account compounded over the next 40 years growing tax-free will be much higher than what I'd save on current taxes on a traditional 401(k). This is only true if you max out your contribution limits. If you start with the same amount of money and have the same marginal tax rate in both years, it doesn't matter which one you pick. Start with $10,000 to invest. With the traditional, you can invest all $10,000. With the Roth, you pay taxes on it and then invest it. Let's assume a tax rate of 25%. So invest $7500. Let's assume that you invest either amount long enough to double four times (forty years at 7% return after inflation is about right). So the traditional has $160,000 and the Roth has $120,000. Now you withdraw them. For simplicity's sake, we'll pretend it's all one year. It's probably over several years, but the math is easier in a single year. With the Roth, you have $120,000. With the traditional, you have to pay tax. Again, let's assume 25%. So that's $40,000, leaving you with $120,000 from the traditional. That is the same amount as the Roth! So it would make sense to If you can max out both, great. You do that for forty years and your retirement will be as financially secure as you can make it. If you can't max them out, the most important thing is the employer match. That's free money. Then you may prefer your Roth IRA to the 401k. Note that you can also roll over your Roth 401k to a Roth IRA. Then you can withdraw your contributions from the Roth IRA without penalty or additional tax. Alternate source. Beyond answering your question, I would still like to reiterate that Roth or traditional does not have a big effect on your investment unless you max them out or you have different tax rates now versus in retirement. It may change other things. For example, you can roll over a Roth 401k to a Roth IRA without paying taxes. And the Roth IRA will act like it was contributed directly. You have to check with your employer what their rollover rules are. They may allow it any time or only at employment separation (when you leave the job). If you do max out your Roth accounts, then they will perform better than the traditional accounts at the same nominal contribution. This is because they are tax free while your returns in the other accounts will have to pay taxes. But it doesn't matter until you hit the limits. Until then, you could just invest the tax savings of the traditional as well as the money you could invest in a Roth.", "title": "" }, { "docid": "482768", "text": "There are a few incorrect assumptions in your question but the TL;DR version is: All, or most, of the withdrawal is taxable income that is reported on Lines 15a (total distribution) and 15b (taxable amount) of Form 1040. None of the distribution is given special treatment as Qualified Dividends or Capital Gains regardless of what happened inside the IRA, and none of the distribution is subject to the 3.8% Net Investment Income Tax that some high-income people need to compute on Form 8960. If the withdrawal is not a Qualified Distribution, it will be subject to a 10% excise tax (tax penalty on premature withdrawal). Not all contributions to Traditional IRAs are deductible from income for the year for which the contribution was made. People with high income and/or coverage by a workplace retirement plan (pension plan, 401(k) plan, 403(b) plan, etc) cannot deduct any contributions that they choose to make to a Traditional IRA. Such people can always make a contribution (subject to them having compensation (earned income such as salary or wages, self-employment income, commissions on sales, etc), but they don't get a tax deduction for it (just as contributions to Roth IRAs are not deductible). Whether it is wise to make such nondeductible contributions to a Traditional IRA is a question on which reasonable people can hold different opinions. Be that as it may, nondeductible contributions to a Traditional IRA create (or add to) what is called the basis of an IRA. They are reported to the IRS on Form 8606 which is attached to the Federal Form 1040. Note that the IRA custodian or trustee is not told that the contributions are not deductible. Earnings on the basis accumulate tax-deferred within the IRA just as do the earnings on the deductible contributions. Now, when you make a withdrawal from your Traditional IRA, no matter which of your various IRA accounts you take the money from, part of the money is deemed to be taken from the basis (and is not subject to income tax) while the rest is pure taxable income. That is, none of the rest is eligible for the reduced taxation rates for Qualified Dividends or Capital Gains and since it does not count as investment income, it is not subject to the 3.8% Net Investment Tax of Form 8960 either. Computation of how much of your withdrawal is nontaxable basis and how much is taxable income is done on Form 8606. Note that you don't get to withdraw your entire basis until such time as when you close all your Traditional IRA accounts. How is all this reported? Well, your IRA custodian(s) will send you Form 1099-R reporting the total amount of the withdrawal, what income tax, if any, was withheld, etc. The custodian(s) don't know what your basis is, and so Box 2b will say that the taxable amount is not determined. You need to fill out Form 8606 to figure out what the taxable amount is, and then report the taxable amount on Line 15b of Form 1040. (The total withdrawal is reported on Line 15a which is not included in the AGI computations). Note that as far as the IRS is concerned, you have only one Traditional IRA. The A in IRA stands for Arrangement, not Account as most everybody thinks, and your Traditional IRA can invest in many different things, stocks, bonds, mutual funds, etc with different custodians if you choose, but your basis is in the IRA, not the specific investment that you made with your nondeductible contribution. That's why the total IRA contribution is limited, not the per-account contribution, and why you need to look that the total value of your IRA in determining the taxable portion, not the specific account(s) from which you withdrew the money. So, how much basis did you withdraw? Well, if you withdrew $W during 2016 and the total value of all your Traditional IRA accounts was $X at the end of 2016 and your total basis in your Traditional IRA is $B, then (assuming that you did not indulge in any Traditional-to-Roth rollovers for 2016), multiply W by B/(W+X) to get the amount of nontaxable basis in the withdrawal. B thus gets reduced for 2017 by amount of basis withdrawal. What if you never made a nondeductible contribution to your Traditional IRA, or you made some nondeductible contributions many years ago and have forgotten about them? Well, you could still fill out Form 8606 reporting a zero basis, but it will just tell you that your basis continues $0. Or, you could just enter the total amount of your withdrawal in Lines 15a and 15b, effectively saying that all of the withdrawal is taxable income to you.

Fidelity has a similar option, or Schwab, or whatever brokerage firm you prefer. IRAs are basically just normal investment accounts, except they don't owe taxes until you withdraw them (and Roth don't even owe them then, though you paid taxes on the funds you deposit).

So, consider the same amount of money sitting in your savings account versus the same amount of money sitting in your Traditional IRA account. While you will earn the same amount of interest in both accounts, you will have to pay taxes each year on the interest earned in the savings account.

If you make an unqualified withdrawal, you owe a penalty (technically named an excise tax) in addition to income tax on the amount withdrawn.

Traditional IRAs are tax deferred (not tax-free as people sometimes mistakenly call them - they're very different), meaning that you don't have to pay taxes on the contributions or profits you make inside the account (e.g. from dividends, interest, profits from stock you sell, etc.). Rather, you pay taxes on any money you withdraw. For Roth IRAs, the contributions are taxed, but you never have to pay taxes on the money inside the account again.

(By way of contrast, people with very high incomes generally aren't allowed to open IRAs). A primary advantage of a Traditional IRA is that you can (in theory, at least) afford to contribute more money to it due to the tax break you're getting.

I am failing to see why would a person get an IRA, instead of just putting the same amount of money into a mutual fund (like Vanguard) or something like that. What am I missing? You are failing to consider the time value of money. Getting $1 now is more valuable to you than a promise to get $1 in a year, even though the nominal amount is the same. With a certain amount of principal now, you can invest it and it will (likely) grow into a bigger amount of money (principal + earnings) at a later time, and we can consider the two to have approximately equivalent value (the principal now has the same value as the principal + earnings later). With pre-tax money in Traditional IRA, the principal + earnings are taxed once at the time of withdrawal. Assuming the same flat rate of tax at contribution and withdrawal, this is equivalent to Roth IRA, where the principal is taxed at the time of contribution, because the principal now has the same value as the principal + earnings later, so the same rate of tax on the two have the same value of tax, even though when you look at nominal amounts, it might seem you are paying a lot less tax with Roth IRA (since the earnings are never \"\"taxed\"\").

You can see they are equivalent even though the nominal amount of tax is different (the lower amount of tax paid now is equivalent to the bigger amount of tax later). With a taxable investment which you will not buy and sell until you take it out, you contribute with after-tax money, and when you take it out, the \"\"earnings\"\" portion is subject to capital-gains tax. But remember that the principal + earnings later is equivalent to the principal now, which is already all taxed once, and if we tax the \"\"earnings\"\" portion later, that is effectively taxing a portion of the money again. Another way to look at it is the contribution is just like the Roth IRA, but the withdrawal is worse because you have to pay capital-gains tax instead of no tax. You can take the same numbers as for the Roth IRA, $1000 * 0.75 * 1.05^10 = $1221.67, but where the $1221.67 - $750 = $471.67 is \"\"earnings\"\" and is taxed again at, say, a 15% capital-gains rate, so you lose another $70.75 in tax and are left with $1150.92. You would need a capital-gains tax rate of 0% to match the advantage of the pre-tax Traditional IRA or Roth IRA. After-tax money in Traditional IRA has a similar problem -- the contribution is after tax, but after it grows into principal + earnings, the \"\"earnings\"\" part is taxed again, except it is worse than the capital-gains case because it is taxed as regular income. Like above, you can take the same numbers as for the Roth IRA, $1000 * 0.75 * 1.05^10 = $1221.67, but where the $471.67 \"\"earnings\"\" is taxed again at 25%, so you lose another $117.92 in tax and are left with $1103.75. So although the nominal amount of tax paid is the same as for pre-tax money in Traditional IRA, it ends up being a lot worse. (Everything I said above about pre-tax money in Traditional IRA, after-tax money in Traditional IRA, and Roth IRA, also applies to pre-tax money in Traditional 401(k), after-tax money in Traditional 401(k), and Roth 401(k), respectively.) Regarding the question you raise in the title of your question, why someone would get contribute to a Traditional IRA if they already have a 401(k), the answer is, mostly, they wouldn't. First, note that if you merely have a 401(k) account but neither you nor your employer contributes to it during the year, then that doesn't prevent you from deducting Traditional IRA contributions for that year, so basically you can contribute to one or the other; so if you only want to contribute below the IRA contribution limit, and don't need the bigger 401(k) contribution limit, and the IRA's investment options are more attractive to you than your 401(k)'s, then it might make sense for you to contribute to only Traditional IRA. If you or your employer is already contributing to your 401(k) during the year, then you cannot deduct your Traditional IRA contributions unless your income is very low, and if your income is really that low, you are in such a low tax bracket that Roth IRA may be more advantageous for you. If you make a Traditional IRA contribution but cannot deduct it, it is a non-deductible Traditional IRA contribution, i.e. it becomes after-tax money in a Traditional IRA, which as I showed in the section above has much worse tax situation in the long run because its earnings are pre-tax and thus taxed again. However, there is one good use for non-deductible Traditional IRA contributions, and that is as one step in a \"\"backdoor Roth IRA contribution\"\". Basically, there is an income limit for being able to make Roth IRA contributions, but there is no income limit for being able to make Traditional IRA contributions or for being able to convert money from Traditional IRA to Roth IRA. So what you can do is make a (non-deductible) Traditional IRA contribution, and then immediately convert it to Roth IRA, and if you did not previously have any pre-tax money in Traditional IRAs, this achieves the same as a regular Roth IRA contribution, with the same tax treatment, but you can do it at any income level.\"", "title": "" } ]

The study included 40 patients above 40 y of age with vasculogenic ED of more than 3 months duration. A dynamic duplex study after intracavernosal injection of a bimix solution (60 mg papaverine + 2 mg phentolamine mesylate) was carried out using a color ultrasound machine. The patients underwent a stress ECG test, carried out on a motor-driven treadmill according to the 'Bruce Protocol'. A total of 12 patients were diagnosed with positive ischemic heart disease (IHD). Their mean peak systolic velocity (PSV) was PSV = 19.58 cm/s. In all, patients were diagnosed with negative IHD; their mean PSV was 36.21 cm/s. A statistically significant difference was observed between patients with positive IHD and patients with negative IHD regarding PSV (P = 0.003). The sensitivity of a PSV of less than 35 cm/s in predicting IHD was 50% with a specificity of 100%. Positive predictive value for abnormal stress ECG to predict a PSV of less than 35 cm/s was 100%. In conclusion, the PSV of cavernosal arteries is a reliable measure for predicting IHD in patients with vasculogenic ED.

Glycolytic metabolism is markedly accelerated in cancer cells, causing the accumulation of glucose (a reducing sugar) and methionine (an amino acid), which can non-enzymatically react and form carcinogenic substances. There is speculation that this reaction produces gaseous sulfur-containing compounds in tumour tissue. The aims of this study were to clarify the products in tumour and to investigate their effect on tumour proliferation. METHODS: Products formed in the reaction between glucose and methionine or its metabolites were analysed in vitro using gas chromatography. Flatus samples from patients with colon cancer and exhaled air samples from patients with lung cancer were analysed using near-edge x-ray fine adsorption structure spectroscopy and compared with those from healthy individuals. The tumour proliferation rates of mice into which HT29 human colon cancer cells had been implanted were compared with those of mice in which the cancer cells were surrounded by sodium hyaluronate gel to prevent diffusion of gaseous material into the healthy cells. RESULTS: Gaseous sulfur-containing compounds such as methanethiol and hydrogen sulfide were produced when glucose was allowed to react with methionine or its metabolites homocysteine or cysteine. Near-edge x-ray fine adsorption structure spectroscopy showed that the concentrations of sulfur-containing compounds in the samples of flatus from patients with colon cancer and in the samples of exhaled air from patients with lung cancer were significantly higher than in those from healthy individuals. Animal experiments showed that preventing the diffusion of sulfur-containing compounds had a pronounced antitumour effect. CONCLUSIONS: Gaseous sulfur-containing compounds are the main products in tumours and preventing the diffusion of these compounds reduces the tumour proliferation rate, which suggests the possibility of a new approach to cancer treatment.", "title": "Generation of gaseous sulfur-containing compounds in tumour tissue and suppression of gas diffusion as an antitumour treatment." }, { "docid": "MED-1700", "text": "Objective To relate dietary fat types to cognitive change in healthy community-based elders. Methods Among 6,183 older participants in the Women’s Health Study, we related intake of major fatty acids (FAs) (saturated [SFA], mono-unsaturated [MUFA], total poly-unsaturated [PUFA], trans-unsaturated) to late-life cognitive trajectory. Serial cognitive testing, conducted over 4 years, began 5 years post-dietary assessment. Primary outcomes were global cognition (averaging tests of general cognition, verbal memory and semantic fluency) and verbal memory (averaging tests of recall). We used analyses of response profiles and logistic regression to estimate multivariable-adjusted differences in cognitive trajectory and risk of worst cognitive change (worst 10%) by fat intake. Results Higher SFA intake was associated with worse global cognitive (p-linear-trend=0.008) and verbal memory (p-linear-trend=0.01) trajectories. There was a higher risk of worst cognitive change, comparing highest vs. lowest SFA quintiles: the multivariable-adjusted odds ratio (OR) (95% confidence interval, CI) was 1.64 (1.04,2.58) for global cognition and 1.65 (1.04,2.61) for verbal memory. By contrast, higher MUFA intake was related to better global cognitive (p-linear-trend<0.001) and verbal memory (p-linear-trend=0.009) trajectories, and lower OR (95% CI) of worst cognitive change in global cognition (0.52 [0.31,0.88]) and verbal memory (0.56 [0.34,0.94]).

Participants Thirty-three adults (17 women) with amnestic mild cognitive impairment ranging in age from 55 to 85 years (mean age,70 years). Intervention Participants were randomized either to a high-intensity aerobic exercise or stretching control group. The aerobic group exercised under the supervision of a fitness trainer at 75% to 85% of heart rate reserve for 45 to 60 min/d, 4 d/wk for 6 months. The control group carried out supervised stretching activities according to the same schedule but maintained their heart rate at or below 50% of their heart rate reserve.

Restriction of methionine may be an important strategy in cancer growth control particularly in cancers that exhibit dependence on methionine for survival and proliferation. Methionine dependence in cancer may be due to one or a combination of deletions, polymorphisms or alterations in expression of genes in the methionine de novo and salvage pathways. Cancer cells with these defects are unable to regenerate methionine via these pathways. Defects in the metabolism of folate may also contribute to the methionine dependence phenotype in cancer. Selective killing of methionine dependent cancer cells in co-culture with normal cells has been demonstrated using culture media deficient in methionine. Several animal studies utilizing a methionine restricted diet have reported inhibition of cancer growth and extension of a healthy life-span. In humans, vegan diets, which can be low in methionine, may prove to be a useful nutritional strategy in cancer growth control. The development of methioninase which depletes circulating levels of methionine may be another useful strategy in limiting cancer growth.

SUBJECTS: Up to the end of 2008, a total of 2820 men and 2950 women were tracked by death registry over the 6·8 years of follow-up. RESULTS: Among 38,077 person-years, an average follow-up 6·5 years, 225 all-cause deaths were identified. Generalized linear models showed beans to be favourable for metabolic syndrome (other than for fasting glucose) in men; in women, beans were favourable for waist circumference and HbA1c. Cumulative logistic regression models for the effect of a bean-free diet on metabolic syndrome scores according to the Taiwanese-modified National Cholesterol Education Program-Adult Treatment Panel III (NCEP-tw) gave adjusted odds ratios of 1·83 in men and 1·45 in women. Cox regression models for the bean-free diet showed an increased hazard ratio for all-cause mortality among women (1·98, 95% CI 1·03, 3·81) but not men (1·28, 95% CI 0·76, 2·16).

Evidence is accumulating to consider ED as a vascular disorder. Common risk factors for atherosclerosis are frequently found in association with ED, and ED is frequently reported in vascular syndromes, such as coronary artery disease (CAD), hypertension, cerebrovascular disease, peripheral arterial disease, and diabetes mellitus. Finally, similar early impairment of endothelium-dependent vasodilatation and late obstructive vascular changes has been reported in both ED and other vascular syndromes. Recently, we proposed a pathophysiologic mechanism to explain the link between ED and CAD called the artery size hypothesis. Given the systemic nature of atherosclerosis, all major vascular beds should be affected to the same extent. However, symptoms rarely become evident at the same time. This difference in rate of occurrence of different symptoms is proposed to be caused by the different size of the arteries supplying different vascular beds that allow a larger vessel to better tolerate the same amount of plaque compared with a smaller one. According to this hypothesis, because penile arteries are smaller in diameter than coronary arteries, patients with ED will seldom have concomitant symptoms of CAD, whereas patients with CAD will frequently complain of ED.

BACKGROUND: An association between ED and ischemic heart disease has been suggested, but it is unknown if it represents a marker of subclinical coronary atherosclerosis. METHODS: We studied 70 consecutive patients with vascular ED, evaluated by penile Doppler, and 73 control subjects with no history of coronary artery disease. We measured traditional coronary risk factors, circulating levels of C-reactive protein (CRP), endothelial function by ultrasound of brachial artery, and coronary artery calcification by multi-slice computed tomography. RESULTS: The patients and the control group were similar for age, race, and coronary risk score. Patients with ED had significantly higher high-sensitivity C-reactive protein levels (2.62 vs. 1.03 mg/l, p < 0.001). Flow-mediated dilation of the brachial artery was more impaired in patients with ED than in controls (2.36 vs. 3.92, p < 0.001). Coronary artery calcification was more frequent in individuals with ED than in control subjects (p = 0.01). Multiple logistic regression analysis showed that patients with ED had an overall odds ratio of 3.68 for having calcium score above the 75th percentile, compared to the controls.

Objective: We prospectively evaluated the association between postdiagnosis soy food consumption and breast cancer outcomes among US and Chinese women by using data from the After Breast Cancer Pooling Project. Design: The analysis included 9514 breast cancer survivors with a diagnosis of invasive breast cancer between 1991 and 2006 from 2 US cohorts and 1 Chinese cohort.

The biochemical mechanism for methionine dependency has been studied extensively, but the fundamental mechanism remains unclear. A number of investigators have attempted to exploit the methionine dependence of tumors for therapeutic effects in vivo. To reduce in vivo methionine in plasma and tumours, dietary and pharmacological treatments have been used. Methionine-free diet or methionine-deprived total parenteral nutrition causes regression of a variety of animal tumours. Alternatively, methionine depletion was achieved by the use of methioninase. This enzyme specifically degrades methionine and inhibits tumour growth in preclinical models. Because of potential toxicity and quality of life problems, prolonged methionine restriction with diet or with methioninase is not suitable for clinical use.

To clarify the role of microbiological culture analysis we aimed to evaluate whether in patients with rheumatoid arthritis (RA) or fibromyalgia (FM) a Mediterranean diet or an 8-day fasting period are associated with changes in fecal flora and whether changes in fecal flora are associated with clinical outcome. Methods During a two-months-period 51 consecutive patients from an Integrative Medicine hospital department with an established diagnosis of RA (n = 16) or FM (n = 35) were included in the study. According to predefined clinical criteria and the subjects' choice the patients received a mostly vegetarian Mediterranean diet (n = 21; mean age 50.9 +/-13.3 y) or participated in an intermittent modified 8-day fasting therapy (n = 30; mean age 53.7 +/- 9.4 y). Quantitative aerob and anaerob bacterial flora, stool pH and concentrations of secretory immunoglobulin A (sIgA) were analysed from stool samples at the beginning, at the end of the 2-week hospital stay and at a 3-months follow-up. Clinical outcome was assessed with the DAS 28 for RA patients and with a disease severity rating scale in FM patients. Results We found no significant changes in the fecal bacterial counts following the two dietary interventions within and between groups, nor were significant differences found in the analysis of sIgA and stool ph. Clinical improvement at the end of the hospital stay tended to be greater in fasting vs. non-fasting patients with RA (p = 0.09).

Oxidation markers were directly correlated with MLSP across species. Mixed glyco- and lipoxidation markers did not correlate with MLSP. However, the lipoxidation marker malondialdehydelysine was inversely correlated with MLSP (r2=0.85; P<0.001). The amino acid compositional analysis revealed that methionine is the only amino acid strongly correlated MLSP and that such correlation is negative (r2=0.93; P<0.001). This trait may contribute to lower steady-state levels of oxidized methionine residues in cellular proteins. These results reinforce the notion that high longevity in homeothermic vertebrates is achieved in part by constitutively decreasing the sensitivity of both tissue proteins and lipids to oxidative damage. This is obtained by modifying the constituent structural components of proteins and lipids, selecting those less sensitive to oxidative modifications.", "title": "Protein methionine content and MDA-lysine adducts are inversely related to maximum life span in the heart of mammals." }, { "docid": "MED-3437", "text": "INTRODUCTION: The use of the penile peak systolic velocity (PSV) measured in the flaccid state during penile color Doppler ultrasound (PCDU) examination has been questioned without substantial evidence. AIM: To assess the validity of PSV measured in the flaccid state during PCDU, in patients consulting for erectile dysfunction (ED). METHODS: A consecutive series of 1,346 (mean age 55.0 +/- 12.0 years) male patients was studied. MAIN OUTCOMES MEASURES: All patients underwent PCDU performed both in the flaccid state and dynamic (after prostaglandin E1 stimulation) conditions. A subset of 20 subjects with uncomplicated type 2 diabetes underwent diagnostic testing for silent coronary heart disease by means of adenosine stress myocardial perfusion scintigraphy (SPECT). In these subjects penile arterial flow was simultaneously assessed by PCDU before and after systemic adenosine administration. RESULTS: Flaccid PSV showed a significant (r = 0.513, P < 0.0001) correlation with dynamic PSV. Receiver operating characteristic (ROC) curve analysis demonstrated that when a threshold of 13 cm/seconds was chosen, flaccid PSV was predictive for dynamic PSV < 25 and <35 cm/seconds with an accuracy of 89% and 82%, respectively. Among the subset of patients who underwent SPECT, an impaired coronary flow reserve (ICFR) occurred in nine cases (45%). When the same threshold of <13 cm/seconds was chosen, PSV before SPECT was predictive of ICFR with an accuracy of 80% (area under the ROC curve = 0.798 +/- 0.10; P < 0.05). After adjustment for confounders, anxiety symptoms were related to dynamic PSV (Adj. r = -0.154, P < 0.05) but not to flaccid PSV. CONCLUSIONS: Our results show that flow in the cavernosal arteries can be routinely evaluated by PCDU in the flaccid state. Performing PCDU only in the flaccid state allows identifying subjects with pathological dynamic PSV with accuracy higher than 80%.

The development of a novel screening method that is as economical and non-invasive as the faecal occult blood test (FOBT) for early detection of colorectal cancer (CRC) is needed. A study was undertaken using canine scent detection to determine whether odour material can become an effective tool in CRC screening. Design Exhaled breath and watery stool samples were obtained from patients with CRC and from healthy controls prior to colonoscopy. Each test group consisted of one sample from a patient with CRC and four control samples from volunteers without cancer. These five samples were randomly and separately placed into five boxes. A Labrador retriever specially trained in scent detection of cancer and a handler cooperated in the tests. The dog first smelled a standard breath sample from a patient with CRC, then smelled each sample station and sat down in front of the station in which a cancer scent was detected. Results 33 and 37 groups of breath and watery stool samples, respectively, were tested. Among patients with CRC and controls, the sensitivity of canine scent detection of breath samples compared with conventional diagnosis by colonoscopy was 0.91 and the specificity was 0.99. The sensitivity of canine scent detection of stool samples was 0.97 and the specificity was 0.99. The accuracy of canine scent detection was high even for early cancer. Canine scent detection was not confounded by current smoking, benign colorectal disease or inflammatory disease. Conclusions This study shows that a specific cancer scent does indeed exist and that cancer-specific chemical compounds may be circulating throughout the body. These odour materials may become effective tools in CRC screening.

Methods Participants in three studies to test the effects of beans on heart disease biomarkers completed the same weekly questionnaire to assess gastrointestinal discomfort issues such as increased flatulence, stool changes, and bloating. Studies 1 and 2 were randomized crossover trials. Participants consumed ½ cup of pinto beans, black-eyed peas, and canned carrots as control (n = 17) in Study 1 for three randomized 8-week phases. For Study 2, participants ate ½ cup baked beans or canned carrots as control (n = 29) for two randomized 8-week phases. Study 3 was a parallel arm trial with 40 subjects receiving ½ cup pinto beans and 40 consuming a control soup for 12 weeks.

Although narrative reviews have been published, no systematic review has synthesized studies on the association between Mediterranean diet adherence and cognitive function or dementia. METHODS: We conducted a systematic review of 11 electronic databases (including Medline) of published articles up to January 2012. Reference lists, selected journal contents, and relevant websites were also searched. Study selection, data extraction, and quality assessment were performed independently by two reviewers using predefined criteria. Studies were included if they examined the association between a Mediterranean diet adherence score and cognitive function or dementia. RESULTS: Twelve eligible papers (11 observational studies and one randomized controlled trial) were identified, describing seven unique cohorts. Despite methodological heterogeneity and limited statistical power in some studies, there was a reasonably consistent pattern of associations. Higher adherence to Mediterranean diet was associated with better cognitive function, lower rates of cognitive decline, and reduced risk of Alzheimer disease in nine out of 12 studies, whereas results for mild cognitive impairment were inconsistent. CONCLUSIONS: Published studies suggest that greater adherence to Mediterranean diet is associated with slower cognitive decline and lower risk of developing Alzheimer disease. Further studies would be useful to clarify the association with mild cognitive impairment and vascular dementia.

BACKGROUND: Observational studies suggest an association between ED and the incidence of CVD. However, whether ED is an independent risk factor of CVD remains controversial. METHODS: The PubMed database was searched through January 2011 to identify studies that met pre-stated inclusion criteria. Reference lists of retrieved articles were also reviewed. Two authors independently extracted information on the designs of the studies, the characteristics of the study participants, exposure and outcome assessments, and control for potential confounding factors. Either a fixed- or a random-effects model was used to calculate the overall combined risk estimates. RESULTS: Twelve prospective cohort studies involving 36,744 participants were included in the meta-analysis. The overall combined relative risks for men with ED compared with the reference group were 1.48 (95% confidence interval [CI]: 1.25 to 1.74) for CVD, 1.46 (95% CI: 1.31 to 1.63) for coronary heart disease, 1.35 (95% CI: 1.19 to 1.54) for stroke, and 1.19 (95% CI: 1.05 to 1.34) for all-cause mortality. Sensitivity analysis restricted to studies with control for conventional cardiovascular risk factors yielded similar results. No evidence of publication bias was observed. CONCLUSIONS: This meta-analysis of prospective cohort studies suggests that ED significantly increases the risk of CVD, coronary heart disease, stroke, and all-cause mortality, and the increase is probably independent of conventional cardiovascular risk factors.

Chitin is an eukaryotic extracellular aminosugar biopolymer, massively produced by most fungal systems and by invertebrates, notably arthropods. Being an integral supportive component in fungal cell wall, insect cuticle, and nematode egg shell, chitin has been considered as a selective target for pesticide action. Throughout the elaborate processes of chitin formation and deposition, only the polymerization events associated with the cell membrane compartment are so far available for chemical interference. Currently, the actinomycetes-derived nucleoside peptide fungicides such as the polyoxins and the insecticidal benzoylaryl ureas have reached commercial pesticide status. The polyoxins and other structurally-related antibiotics like nikkomycins are strong competitive inhibitors of the polymerizing enzyme chitin synthase. The exact biochemical lesion inflicted by the benzoylaryl ureas is still elusive, but a post-polymerization event, such as translocation of chitin chains across the cell membrane, is suggested. Hydrolytic degradation of the chitin polymer is essential for hyphal growth, branching, and septum formation in fungal systems as well as for the normal molting of arthropods. Recently, insect chitinase activity was strongly and specifically suppressed by allosamidin, an actimomycetes-derived metabolite. In part, the defense mechanism in plants against invasion of pathogens is associated with induced chitinases. Chitin, chitosan, and their oligomers are able to act as elicitors which induce enhanced levels of chitinases in various plants. Lectins which bind to N-acetyl-D-glucosamine strongly interfere with fungal and insect chitin synthases.

On the other hand, many studies have consistently shown that dietary restriction (DR) in rodents also decreases mitochondrial ROS (mtROS) production and oxidative damage to mitochondrial DNA and proteins. It has been observed that protein restriction also decreases mtROS generation and oxidative stress in rat liver, whereas neither carbohydrate nor lipid restriction change these parameters. This is interesting because protein restriction also increases maximum longevity in rodents (although to a lower extent than DR) and is a much more practicable intervention for humans than DR, whereas neither carbohydrate nor lipid restriction seem to change rodent longevity. Moreover, it has been found that isocaloric methionine restriction also decreases mtROS generation and oxidative stress in rodent tissues, and this manipulation also increases maximum longevity in rats and mice. In addition, excessive dietary methionine also increases mtROS generation in rat liver. These studies suggest that the reduced intake of dietary methionine can be responsible for the decrease in mitochondrial ROS generation and the ensuing oxidative damage that occurs during DR, as well as for part of the increase in maximum longevity induced by this dietary manipulation.

Methods Beginning in 1980, a semi-quantitative food frequency questionnaire was administered every four years to Nurses’ Health Study participants. In 1995–2001, we began measuring cognitive function in 16,010 participants, aged ≥70 years; follow-up assessments were conducted twice, at two-year intervals. To ascertain long-term diet, we averaged dietary variables from 1980 through the initial cognitive interview. Using multivariable-adjusted, mixed linear regression, we estimated mean differences in slopes of cognitive decline by long-term berry and flavonoid intakes. Results Greater intakes of blueberries and strawberries were associated with slower rates of cognitive decline (e.g., for a global score averaging all six cognitive tests, for blueberries: p-trend=0.014 and mean difference=0.04 [95% CI=0.01, 0.07] comparing extreme categories of intake; for strawberries: p-trend= 0.022 and mean difference=0.03 [95% CI=0.00, 0.06] comparing extreme categories of intake), after adjusting for multiple potential confounders.

AIM: In the present study, we explored the relation between consumption of a Mediterranean-type diet and sexual function in a population of type 2 diabetic women. METHODS: Patients with type 2 diabetes were enrolled if they had a diagnosis of type 2 diabetes for at least six months but less than 10 years, age 35-70 years, body mass index (BMI) of 24 or higher, HbA1c of 6.5% or higher, treatment with diet or oral drugs. All diabetic patients were invited to complete a food-frequency questionnaire and self-report measures of sexual function. A total of 595 (90.2%) of the 659 women completed both questionnaires and were analyzed in the present study. MAIN OUTCOME MEASURES: Adherence to a Mediterranean diet was assessed by a 9-point scale that incorporated the salient characteristics of this diet (range of scores, 0-9, with higher scores indicating greater adherence). The Female Sexual Function Index (FSFI) was used for assessing the key dimensions of female sexual function. RESULTS: Diabetic women with the highest scores (6-9) had lower BMI, waist circumference, and waist-to-hip ratio, a lower prevalence of depression, obesity and metabolic syndrome, a higher level of physical activity, and better glucose and lipid profiles than the diabetic women who scored <3 points on the scale. The proportion of sexually active women showed a significant increase across tertiles of adherence to Mediterranean diet (from 54.2% to 65.1%, P = 0.01).

The main strategy includes application of four pillars of prevention: 1) early identification of AD vascular risk factors; 2) early detection of AD vascular risk factors; 3) early intervention of AD vascular risk factors based on evidence-based medical decisions; 4) patient follow-up to assess and modify interventions as needed. Tandem to these four pillars of prevention, a proactive lifestyle consisting of a healthy diet coupled to physical and mental activity should be applied as part of any therapeutic intervention.

Studies were sought in PubMed up to October 31, 2012. Maximally adjusted effect estimates were extracted; separate analyses were performed for high and moderate adherence. RESULTS: Twenty-two eligible studies were included (11 covered stroke, 9 covered depression, and 8 covered cognitive impairment; only 1 pertained to Parkinson's disease). High adherence to Mediterranean diet was consistently associated with reduced risk for stroke (RR = 0.71, 95% confidence interval [CI] = 0.57-0.89), depression (RR = 0.68, 95% CI = 0.54-0.86), and cognitive impairment (RR = 0.60, 95% CI = 0.43-0.83). Moderate adherence was similarly associated with reduced risk for depression and cognitive impairment, whereas the protective trend concerning stroke was only marginal. Subgroup analyses highlighted the protective actions of high adherence in terms of reduced risk for ischemic stroke, mild cognitive impairment, dementia, and particularly Alzheimer disease. Meta-regression analysis indicated that the protective effects of Mediterranean diet in stroke prevention seemed more sizeable among males. Concerning depression, the protective effects of high adherence seemed independent of age, whereas the favorable actions of moderate adherence seemed to fade away with more advanced age.

A cure for AD appears unlikely when significant cognitive loss has occurred because the neuronal networks that controlled the perturbed cognitive abilities are either dead or irreversibly damaged and replacing them, even if it were technically possible, would not reconstruct the intellectual identity of the host. Prevention of risk factors to sporadic AD is a more realistic stratagem and treatment, when indicated, ideally should begin in cognitively intact individuals as part of a mass screening effort. Prevention of modifiable risk factors to AD is cost-effective because it reduces hospice or hospital stay, repeated doctor visits, and long-term care. Presently, neurocognitive and neuroimaging tests are used with partial success in identifying persons at higher risk of AD but these tests can not pinpoint either a cause or a specific intervention that could attenuate disease progress. We previously proposed that carotid artery ultrasound +echocardiography together with ankle-brachail index (CAUSE+ABI) as mass screening tests in asymptomatic persons could detect not only cardio-cerebrovascular risk factors to AD, but also identify an indicated intervention.

One approach is to modify nongenetic risk factors, for instance by lowering elevated plasma homocysteine using B vitamins.

Here, we go further by demonstrating that B-vitamin treatment reduces, by as much as seven fold, the cerebral atrophy in those gray matter (GM) regions specifically vulnerable to the AD process, including the medial temporal lobe. In the placebo group, higher homocysteine levels at baseline are associated with faster GM atrophy, but this deleterious effect is largely prevented by B-vitamin treatment. We additionally show that the beneficial effect of B vitamins is confined to participants with high homocysteine (above the median, 11 µmol/L) and that, in these participants, a causal Bayesian network analysis indicates the following chain of events: B vitamins lower homocysteine, which directly leads to a decrease in GM atrophy, thereby slowing cognitive decline.

Accumulation of AGEs is a normal feature of aging, but is accelerated in AD, where AGEs can be detected in amyloid plaques and neurofibrillary tangles.

We suggest that methylglyoxal is one of the major carbonyl species responsible for the formation of AGEs. We propose that one promising pharmacological approach to prevent the formation of AGEs would be to lower the methylglyoxal concentration. This can be achieved, for example, by decreasing the concentration of methylglyoxal precursors such as d-glyceraldehyde-3-phosphate by allowing a higher flux through the pentose phosphate pathway or by increasing methylglyoxal detoxification through the glyoxalase system.

SIRT1 overexpression prevents oxidative stress-induced apoptosis and increases resistance to oxidative stress through regulation of the FOXO family of forkhead transcription factors.

Fifty years ago endemic foci of ALS with a frequency one hundred times that in the rest of the world attracted attention since they offered the possibility of finding the cause for non-endemic ALS throughout the world. Research on Guam suggested that ALS, Parkinson's disease and dementia (the ALS/PDC complex) was due to a neurotoxic non-protein amino acid, beta-methylamino-L-alanine (BMAA), in the seeds of the cycad Cycas micronesica. Recent discoveries that found that BMAA is produced by symbiotic cyanobacteria within specialized roots of the cycads; that the concentration of protein-bound BMAA is up to a hundred-fold greater than free BMAA in the seeds and flour; that various animals forage on the seeds (flying foxes, pigs, deer), leading to biomagnification up the food chain in Guam; and that protein-bound BMAA occurs in the brains of Guamanians dying of ALS/PDC (average concentration 627 microg/g, 5 mM) but not in control brains have rekindled interest in BMAA as a possible trigger for Guamanian ALS/PDC. Perhaps most intriguing is the finding that BMAA is present in brain tissues of North American patients who had died of Alzheimer's disease (average concentration 95 microg/g, 0.8mM); this suggests a possible etiological role for BMAA in non-Guamanian neurodegenerative diseases. Cyanobacteria are ubiquitous throughout the world, so it is possible that all humans are exposed to low amounts of cyanobacterial BMAA, that protein-bound BMAA in human brains is a reservoir for chronic neurotoxicity, and that cyanobacterial BMAA is a major cause of progressive neurodegenerative diseases including ALS worldwide. Though Montine et al., using different HPLC method and assay techniques from those used by Cox and colleagues, were unable to reproduce the findings of Murch et al., Mash and colleagues using the original techniques of Murch et al. have recently confirmed the presence of protein-bound BMAA in the brains of North American patients dying with ALS and Alzheimer's disease (concentrations >100 microg/g) but not in the brains of non-neurological controls or Huntington's disease. We hypothesize that individuals who develop neurodegenerations may have a genetic susceptibility because of inability to prevent BMAA accumulation in brain proteins and that the particular pattern of neurodegeneration that develops depends on the polygenic background of the individual.", "title": "Beyond Guam: the cyanobacteria/BMAA hypothesis of the cause of ALS and other neurodegenerative diseases." }, { "docid": "MED-4590", "text": "Increased oxidative stress contributes to the decline in cognitive performance during normal aging and in neurodegenerative conditions such as Alzheimer's disease.

We assessed the epidemiology of Alzheimer's disease and other forms of dementia in China between 1990, and 2010, to improve estimates of the burden of disease, analyse time trends, and inform health policy decisions relevant to China's rapidly ageing population. METHODS: In our systematic review we searched for reports of Alzheimer's disease or dementia in China, published in Chinese and English between 1990 and 2010. We searched China National Knowledge Infrastructure, Wanfang, and PubMed databases. Two investigators independently assessed case definitions of Alzheimer's disease and dementia: we excluded studies that did not use internationally accepted case definitions. We also excluded reviews and viewpoints, studies with no numerical estimates, and studies not done in mainland China. We used Poisson regression and UN demographic data to estimate the prevalence (in nine age groups), incidence, and standardised mortality ratio of dementia and its subtypes in China in 1990, 2000, and 2010. FINDINGS: Our search returned 12,642 reports, of which 89 met the inclusion criteria (75 assessed prevalence, 13 incidence, and nine mortality). In total, the included studies had 340,247 participants, in which 6357 cases of Alzheimer's disease were recorded. 254,367 people were assessed for other forms of dementia, of whom 3543 had vascular dementia, frontotemporal dementia, or Lewy body dementia. In 1990 the prevalence of all forms of dementia was 1·8% (95% CI 0·0-44·4) at 65-69 years, and 42·1% (0·0-88·9) at age 95-99 years. In 2010 prevalence was 2·6% (0·0-28·2) at age 65-69 years and 60·5% (39·7-81·3) at age 95-99 years. The number of people with dementia in China was 3·68 million (95% CI 2·22-5·14) in 1990, 5·62 million (4·42-6·82) in 2000, and 9·19 million (5·92-12·48) in 2010. In the same period, the number of people with Alzheimer's disease was 1·93 million (1·15-2·71) in 1990, 3·71 million (2·84-4·58) people in 2000, and 5·69 million (3·85-7·53) in 2010. The incidence of dementia was 9·87 cases per 1000 person-years, that of Alzheimer's disease was 6·25 cases per 1000 person-years, that of vascular dementia was 2·42 cases per 1000 person-years, and that of other rare forms of dementia was 0·46 cases per 1000 person-years. We retrieved mortality data for 1032 people with dementia and 20,157 healthy controls, who were followed up for 3-7 years. The median standardised mortality ratio was 1·94:1 (IQR 1·74-2·45).

DESIGN AND SETTING: The Honolulu Heart Program is a prospective population-based study of cardiovascular disease established in 1965. Prevalence estimates were computed from cases identified at the 1991 to 1993 examination. Cognitive performance was assessed using standardized methods, instruments, and diagnostic criteria. PARTICIPANTS: Subjects were 3734 Japanese-American men (80% of surviving cohort) aged 71 through 93 years, living in the community or in institutions. MAIN OUTCOME MEASURES: Age-specific, age-standardized, and cohort prevalence estimates were computed for dementia (all cause) defined by 2 sets of diagnostic criteria and 4 levels of severity. Prevalence levels for Alzheimer disease and vascular dementia were also estimated. RESULTS: Dementia prevalence by Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised ranged from 2.1% in men aged 71 through 74 years to 33.4% in men aged 85 through 93 years.

Studies of newly diagnosed dementia are required in order to establish whether the elevated homocysteine levels precede the onset of dementia or result from dementia-related nutritional and vitamin deficiencies. METHODS: A total of 1092 subjects without dementia (667 women and 425 men; mean age, 76 years) from the Framingham Study constituted our study sample. We examined the relation of the plasma total homocysteine level measured at base line and that measured eight years earlier to the risk of newly diagnosed dementia on follow-up. We used multivariable proportional-hazards regression to adjust for age, sex, apolipoprotein E genotype, vascular risk factors other than homocysteine, and plasma levels of folate and vitamins B12 and B6. RESULTS: Over a median follow-up period of eight years, dementia developed in 111 subjects, including 83 given a diagnosis of Alzheimer's disease. The multivariable-adjusted relative risk of dementia was 1.4 (95 percent confidence interval, 1.1 to 1.9) for each increase of 1 SD in the log-transformed homocysteine value either at base line or eight years earlier. The relative risk of Alzheimer's disease was 1.8 (95 percent confidence interval, 1.3 to 2.5) per increase of 1 SD at base line and 1.6 (95 percent confidence interval, 1.2 to 2.1) per increase of 1 SD eight years before base line.

Participants Fifty patients with PD, 43 controls, and 20 patients with Alzheimer disease. Main Outcome Measures Levels of 16 organochlorine pesticides in serum samples. Results β-Hexachlorocyclohexane (β-HCH) was more often detectable in patients with PD (76%) compared with controls (40%) and patients with Alzheimer disease (30%).

The findings lead the authors to suggest a possible role of the inhalation of aluminium dust in pre-clinical mild cognitive disorder which might prelude Alzheimer's disease (AD) or AD-like neurological deterioration. METHODS: The investigation involved a standardised occupational and medical history with particular attention to exposure and symptoms, assessments of neurotoxic metals in serum: aluminium (Al-s), copper (Cu-s) and zinc (Zn-s), and in blood: manganese (Mn-b), lead (Pb-b) and iron (Fe-b). Cognitive functions were assessed by the Mini Mental State Examination (MMSE), the Clock Drawing Test (CDT) and auditory evoked Event-Related Potential (ERP-P300). To detect early signs of mild cognitive impairment (MCI), the time required to solve the MMSE (MMSE-time) and CDT (CDT-time) was also measured. RESULTS: Significantly higher internal doses of Al-s and Fe-b were found in the ex-employees compared to the control group. The neuropsychological tests showed a significant difference in the latency of P300, MMSE score, MMSE-time, CDT score and CDT-time between the exposed and the control population. P300 latency was found to correlate positively with Al-s and MMSE-time. Al-s has significant effects on all tests: a negative relationship was observed between internal Al concentrations, MMSE score and CDT score; a positive relationship was found between internal Al concentrations, MMSE-time and CDT-time. All the potential confounders such as age, height, weight, blood pressure, schooling years, alcohol, coffee consumption and smoking habit were taken into account. CONCLUSIONS: These findings suggest a role of aluminium in early neurotoxic effects that can be detected at a pre-clinical stage by P300, MMSE, MMSE-time, CDT-time and CDT score, considering a 10 micrograms/l cut-off level of serum aluminium, in aluminium foundry workers with concomitant high blood levels of iron.

REPORTING PERIOD: 1995-1996. DESCRIPTION OF SYSTEMS: This report uses data from CDC's National Center for Health Statistics (NCHS) to report on leading causes of death in 1996 (from the National Vital Statistics System), major causes of hospitalization (1996 National Hospital Discharge Survey [NHDSI), and major chronic conditions (1995 National Health Interview Survey [NHIS]). The National Vital Statistics System compiles information regarding all death certificates filed in the United States. NHDS is an annual probability sample of discharges from nonfederal, short-stay hospitals. NHIS is an ongoing annual cross-sectional household survey of the U.S. civilian, noninstitutionalized population. In addition, health-care expenditures for older adults are examined by using information obtained from published reports from the U.S. Health Care Financing Administration (HCFA) and health-services literature. RESULTS: The leading causes of death among adults aged > or =65 years were heart disease (1,808 deaths/100,000 population), malignant neoplasms (1,131/100,000), and cerebrovascular disease (415/100,000). Several leading causes of mortality among older adults differed by race, with deaths caused by Alzheimer's disease more frequent among whites and deaths caused by diabetes, kidney diseases, septicemia, and hypertension more frequent among blacks. Rates of hospitalization and length of hospital stays increased with age. Hospitalizations for heart disease represented the highest proportion of all discharges among older adults (23%). Discharge rates for malignant neoplasms, stroke, and pneumonia were similar for adults aged > or =65 years and, as with heart disease, were higher for men than for women. However, the rate of hospitalization for fractures among women exceeded the rate among men. Arthritis was the most prevalent chronic condition among adults aged > or =65 years (48.9/100 adults), followed by hypertension (40.3/100) and heart disease (28.6/100). In 1995, adults aged > or =65 years comprised 13% of the population but accounted for 35% of total personal health care dollars spent ($310 billion), and real per capita personal health-care expenditure for this age group increased at an average annual rate of 5.8% during 1985-1995. Projections for future medical expenditures for older adults vary; however, all project substantial increases after the year 2000. Hip fracture, dementia, and urinary incontinence are discussed as examples of prevalent and costly health conditions among older adults that differ in potential for prevention. These conditions were selected because they result in substantial medical and social costs and they differ in potential for prevention. INTERPRETATION: The higher prevalence of serious and costly health conditions among adults aged > or =65 years highlights the importance of implementing preventive health measures in this population.

It reduces pathology in transgenic models of Alzheimer's disease (AD) and is a promising candidate for treating human AD. The purpose of the current study is to generate tolerability and preliminary clinical and biomarker efficacy data on curcumin in persons with AD. Methods We performed a 24-week randomized, double blind, placebo-controlled study of Curcumin C3 Complex® with an open-label extension to 48 weeks. Thirty-six persons with mild-to-moderate AD were randomized to receive placebo, 2 grams/day, or 4 grams/day of oral curcumin for 24 weeks. For weeks 24 through 48, subjects that were receiving curcumin continued with the same dose, while subjects previously receiving placebo were randomized in a 1:1 ratio to 2 grams/day or 4 grams/day. The primary outcome measures were incidence of adverse events, changes in clinical laboratory tests and the Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-Cog) at 24 weeks in those completing the study. Secondary outcome measures included the Neuropsychiatric Inventory (NPI), the Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) scale, levels of Aβ1-40 and Aβ1-42 in plasma and levels of Aβ1-42, t-tau, p-tau181 and F2-isoprostanes in cerebrospinal fluid. Plasma levels of curcumin and its metabolites up to four hours after drug administration were also measured. Results Mean age of completers (n = 30) was 73.5 years and mean Mini-Mental Status Examination (MMSE) score was 22.5. One subject withdrew in the placebo (8%, worsened memory) and 5/24 subjects withdrew in the curcumin group (21%, 3 due to gastrointestinal symptoms). Curcumin C3 Complex® was associated with lowered hematocrit and increased glucose levels that were clinically insignificant. There were no differences between treatment groups in clinical or biomarker efficacy measures. The levels of native curcumin measured in plasma were low (7.32 ng/mL). Conclusions Curcumin was generally well-tolerated although three subjects on curcumin withdrew due to gastrointestinal symptoms.

Associations between each lipid profile and AD pathology were examined by analysis of covariance and logistic regression analyses. RESULTS: Adjusted means of TC, LDLC, TC/HDLC, LDLC/HDLC, and non-HDLC (defined as TC-HDLC) were significantly higher in subjects with NPs, even in sparse to moderate stages (CERAD = 1 or 2), compared to subjects without NPs in multivariate models including APOE ε4 carrier and other confounding factors. The subjects in the highest quartiles of these lipid profiles had significantly higher risks of NPs compared to subjects in the lower respective quartiles, which may suggest a threshold effect.

Cancer-associated fibroblasts (CAFs) are constituents of tumor microenvironments
[ { "docid": "6944800", "text": "Cancers develop in complex tissue environments, which they depend on for sustained growth, invasion and metastasis. Unlike tumor cells, stromal cell types within the tumor microenvironment (TME) are genetically stable and thus represent an attractive therapeutic target with reduced risk of resistance and tumor recurrence. However, specifically disrupting the pro-tumorigenic TME is a challenging undertaking, as the TME has diverse capacities to induce both beneficial and adverse consequences for tumorigenesis. Furthermore, many studies have shown that the microenvironment is capable of normalizing tumor cells, suggesting that re-education of stromal cells, rather than targeted ablation per se, may be an effective strategy for treating cancer. Here we discuss the paradoxical roles of the TME during specific stages of cancer progression and metastasis, as well as recent therapeutic attempts to re-educate stromal cells within the TME to have anti-tumorigenic effects.", "title": "Microenvironmental regulation of tumor progression and metastasis" } ]

It is becoming clear that the crosstalk between the cancer cells and the CAFs plays a key role in the progression of cancer, and understanding this mutual relationship would eventually enable us to treat cancer patients by targeting CAFs.

We have recently demonstrated that cancer-associated fibroblasts (CAFs) elicit a redox-dependent epithelial-mesenchymal transition (EMT) in prostate cancer (PCa) cells, driven by cycloxygenase-2/hypoxia-inducible factor-1 (HIF-1)/nuclear factor-κB pathway and enhancing tumor aggressiveness. Here, we investigated the involvement of microRNAs (miRNAs) in tumor-stroma interplay to identify possible tools to counteract oxidative stress and metastasis dissemination. RESULTS We found that miR-205 is the most downmodulated miRNA in PCa cells upon CAF stimulation, due to direct transcriptional repression by HIF-1, a known redox-sensitive transcription factor. Rescue experiments demonstrated that ectopic miR-205 overexpression in PCa cells counteracts CAF-induced EMT, thus impairing enhancement of cell invasion, acquisition of stem cell traits, tumorigenicity, and metastatic dissemination. In addition, miR-205 blocks tumor-driven activation of surrounding fibroblasts by reducing pro-inflammatory cytokine secretion. INNOVATION Overall, such findings suggest miR-205 as a brake against PCa metastasis by blocking both the afferent and efferent arms of the circuit between tumor cells and associated fibroblasts, thus interrupting the pro-oxidant and pro-inflammatory circuitries engaged by reactive stroma. CONCLUSION The evidence that miR-205 replacement in PCa cells is able not only to prevent but also to revert the oxidative/pro-inflammatory axis leading to EMT induced by CAFs sets the rationale for developing miRNA-based approaches to prevent and treat metastatic disease.", "title": "miR-205 hinders the malignant interplay between prostate cancer cells and associated fibroblasts." }, { "docid": "10812605", "text": "Fibroblasts regulate the structure and function of healthy tissues, participate transiently in tissue repair after acute inflammation, and assume an aberrant stimulatory role during chronic inflammatory states including cancer.

However, the role of cancer-associated fibroblasts (CAFs) in HCC metastasis remains obscure. Here, we reported that CAFs promote the migration and invasion of HCC cells in vitro and facilitate the HCC metastasis to the bone, brain and lung in NOD/SCID mice. The RayBio human chemokine antibody array revealed that CAFs secret higher levels of CCL2, CCL5, CCL7 and CXCL16 than peri-tumor fibroblasts. CCL2 and CCL5 increase the migration but not the invasion of HCC cells, while CCL7 and CXCL16 promote both migration and invasion of HCC cells.

In accordance with this idea, we have recently proposed that the Warburg effect in cancer cells may be due to culturing cancer cells by themselves, out of their normal stromal context or tumor microenvironment. In fact, when cancer cells are co-cultured with fibroblasts, then cancer cells increase their mitochondrial mass, while fibroblasts lose their mitochondria. An in depth analysis of this phenomenon reveals that aggressive cancer cells are \"parasites\" that use oxidative stress as a \"weapon\" to extract nutrients from surrounding stromal cells. Oxidative stress in fibroblasts induces the autophagic destruction of mitochondria, by mitophagy. Then, stromal cells are forced to undergo aerobic glycolysis, and produce energy-rich nutrients (such as lactate and ketones) to \"feed\" cancer cells. This mechanism would allow cancer cells to seed anywhere, without blood vessels as a food source, as they could simply induce oxidative stress wherever they go, explaining how cancer cells survive during metastasis. We suggest that stromal catabolism, via autophagy and mitophagy, fuels the anabolic growth of tumor cells, promoting tumor progression and metastasis.

In this model, cancer cells induce oxidative stress in cancer-associated fibroblasts, which then acts as a \"metabolic\" and \"mutagenic\" motor to drive tumor-stroma co-evolution, DNA damage and aneuploidy in cancer cells. More specifically, we show that an acute loss of Cav-1 expression leads to mitochondrial dysfunction, oxidative stress and aerobic glycolysis in cancer associated fibroblasts. Also, we propose that defective mitochondria are removed from cancer-associated fibroblasts by autophagy/mitophagy that is induced by oxidative stress. As a consequence, cancer associated fibroblasts provide nutrients (such as lactate) to stimulate mitochondrial biogenesis and oxidative metabolism in adjacent cancer cells (the \"Reverse Warburg Effect\"). We provide evidence that oxidative stress in cancer-associated fibroblasts is sufficient to induce genomic instability in adjacent cancer cells, via a bystander effect, potentially increasing their aggressive behavior.

In support of this notion, treatment with anti-oxidants (such as N-acetyl-cysteine, metformin and quercetin) or NO inhibitors (L-NAME) was sufficient to reverse many of the cancer-associated fibroblast phenotypes that we describe. Thus, cancer cells use \"oxidative stress\" in adjacent fibroblasts (i) as an \"engine\" to fuel their own survival via the stromal production of nutrients and (ii) to drive their own mutagenic evolution towards a more aggressive phenotype, by promoting genomic instability. We also present evidence that the \"field effect\" in cancer biology could also be related to the stromal production of ROS and NO species. eNOS-expressing fibroblasts have the ability to downregulate Cav-1 and induce mitochondrial dysfunction in adjacent fibroblasts that do not express eNOS.

How do I build wealth?
[ { "docid": "296799", "text": "\"You got some answers that essentially inform you that CEOs that have £200k written on their paysheet may in fact get much more. I'll take the opposite point of view and talk about people who (according to whatever definition) have a £200k/year income. How can they afford it Guess no 1: not all of them can (in the sense that it is quite possible to end up with negative net worth at £200k/year income - particularly if you immediately want to show off with brand new luxury cars, luxury holidays and a large house in a very representative region). Guess no 2: not all of the £200k/year CEOs are equally visible. There is a trade-off between going for wealth, large house, and luxury car. I deliberately ordered the three points according to increased display of \"\"wealth\"\". However, display of wealth usually comes at a cost (in a very monetary sense). And there are ways to get much display without having much wealth (see below: lease the car, also the mortgage on the house usually isn't displayed on the outside). You also need to take into account how long they are already building up wealth. I guess the typical CEO with £200k/year you're asking about did not just finish school and enter his work life in this position. It would be very interesting to see how income, accumulating wealth (and possibly \"\"displayed wealth\"\") correlate. My guess is that the correlation between income and accumulated wealth isn't that high, and the correlation between displayed and actual wealth is probably even lower. they possess luxury cars, large house and huge savings Are you sure these are the same managers? E.g. the ones with the huge savings are and the ones with the luxury cars? I'm asking particularly about the luxury cars, because such cars loose value very quickly and/or are often not owned by the driver but rather by the bank or leasing company. Which on the other hand offers the more savings-oriented CEO who is not that much interested in having a brand new luxury car the possibility to go for a one-year-old and save the rest. Knowing that, your CEO should be able to buy a one-year-old Mercedes SL 350 / year. Or a new one every 1 1/2 years (without building up savings or buying a house). However, building up wealth will be much faster with the CEO going for the one-year-old as the brand-new car option amounts to loosing ca. £20 - 30k within a year. An even-more-savings-oriented CEO who keeps his existing Mercedes 300 TD for another few years, thinking that this conservative choice of car will be trust-inspiring to the customers. Or goes for the SLK thinking that most people anyways don't know that the K between SL and SLK halves the price... However, if you just want to be seen with the car: after an initial payment of say £8-10k, you can get a decent SLK 350 (not the base model, either) at a monthly rate of ca. 600£/month or less than £7k/year. Note however, that this money does not count towards any kind of wealth, it's just renting a nice car. In other words: If driving the SLK 350 is your absolute goal, you could in theory have that with a net salary of £25k/year (according to your tax calculation, that should be somewhere around £35k / year gross), if you have the savings for the initial payment (being able to make the initial payment may also help convincin the leasing company that you're serious about it and able to pay your rates). There are also huge differences in value between large houses, compare e.g. these 2: And, last but not least, there is a decided one-way component in the timing of priorities here: it is much easier to go and get a luxury car when you have savings than first going for the luxury car and then trying to make up with the savings... I forgot to answer the question in the caption of your question: How do I build wealth By going on to live as if your income were only £50k (as far as that is compatible with your job) - I gather the median gross income in the UK is about £30k, so aiming at £50k leaves you a very comfortable budget for luxury spending. If you want to build up wealth faster, adjust that. In general, if you can manage to withhold much of any income increase from spending, that will help (trivial but powerful truth). From the leasing calculation you can conclude that you basically have no chance to show off your wealth by luxury cars. That is, you'd need to go for luxury cars that are completely incompatible with with building if you want to show your built up wealth by the car: there are too many people who even destroy their existing wealth in order to display luxury. At least if anyone is around who has either a correct idea what luxury cars cost (or don't cost) or will look that up in the internet. Also, people who know such things may also have the idea that the probability that such a car was downright paid (wealth) is small compared to the probability of meeting a leased or (mortgaged) car. Which means, the plan to show off doesn't work out that well with the people you'd want to impress. As for the other people: just a bit of display you can get far cheaper: If you really want to drive the SLK, rent it for an occasion (weekend) rather than for years. I met a sales manager who told me which rental cars they get when important customers from far east are visiting. The rest of the year they drive normal business cars. You may want to choose a rental company that doesn't write their name on the license plate. Apply the same ideas to the decision of buying a house. Think about what you want for yourself, and then look where you can get how much of that for how much money.

However, remember that having wealth makes it easier to build further wealth. As Victor pointed out, having wealth allows you to increase your wealth in different kinds of investments. Also, it gives you access to more human capital, e.g. wealth management services at firms like Northern Trust, a greater ability to diversify into investments like hedge funds, more abilities to invest abroad through foreign trusts, etc. Also, you have to realize that wealthier people often pay a lower percentage in taxes than people who earn a salary. In the US, long-term capital gains are taxed at a much lower rate than income, so wealthy individuals who earn much of their money from long-term investments won't pay nearly as high a rate. In my case, my current salary places me at the top of the 25% tax bracket (in the US), but if I earned all of my income through long-term capital gains instead of salary, I would only pay around 15-20% in taxes. Plus, I could afford numerous tax accounting firms to help me find ways to pay fewer taxes. It's not altruism that causes CEOs like Steve Jobs and Mark Zuckerberg to take a $1 salary. This isn't directly related to CEOs, and I'm not leveling accusations of corruption against high net worth individuals, but I remember spending a few months in a small town in a country known for its corruption. The mayor had recently purchased a home worth the equivalent of several million dollars, on his annual civil servant salary of approximately $20K. One of the students asked him how he managed to afford such a sizable property, and he replied \"\"I live very frugally.\"\" This is probably a relatively rare case (I'm sure it depends on the country), but nevertheless, it illustrates another way that some people build wealth.\"", "title": "" }, { "docid": "82304", "text": "Many CEOs I have heard of earn a lot more than 200k.

Especially if much of your own money is in the stock market, it may be beneficial to take out a loan to buy something compared to selling other assets to raise the same amount of cash. Even going by the likely relatively conservative £200K/year before taxes, you are looking at a very nice house going for perhaps around 3-5 years' worth of pre-tax income. Let's say you have good contacts at the bank and can secure a loan for £500K at 3.5% interest (not at all unreasonable if you make half that before taxes in a single year and purchase something that can be used as collateral for the money borrowed; with a bit of negotiating, I wouldn't be surprised if one could push the interest rate even lower, and stock in a publicly traded company can also trivially be used as collateral). That's less than £1500/month in interest, before any applicable tax effects -- less than 10% of the before-tax income. And like @Victor wrote, I think it's reasonable to say that especially if the company is publicly traded, the CEO makes more than £200K/year. Given an income of £200K/year and assuming 30% taxes on that amount (the marginal tax would likely be higher, and this includes e.g. interest expense deductions), the money left over after taxes and interest payments on a £500K 3.5% debt is still about £10K/month.

To add to Lan's great answer, if one is \"\"poor\"\" because they don't have enough income to build wealth (invest), then there are only two ways to change the situation - earn more or spend less. Neither are easy but both are usually possible. One can take on side jobs, look for a better-paying career, etc. Cutting spending can also be hard but is generally easier than adding income. In general, wealth building is more about what you do with your income than about how much you make. Obviously the more you make, the easier it is, but just about anyone can build wealth if they spend less than they make. Once your NET income is high enough that you have investible income, THEN you can start building wealth.

Just having $100 is not going to make you \"\"rich\"\". There is a practical limit to how much return you can make short of high-risk activities like gambling, lottery tickets, etc. (I have actually seen this as a justification for playing the lottery, which I disagree with but is an interesting point). If you just invest $100 at 25% per year (for illustration - traditional investments typically only make 10-12% on average), in 10 years you'll have about $931. If instead you invest $100 per month at 12% annualized, in 10 years you'll have over $23,000.

This is in Australia so it is difficult for me to have complete perspective. However, I can speak about the US of A. To your first point relatively few people inherit their wealth. According to a brief web search about 38% of billionaires, and 20% of millionaires inherited their wealth. The rest are self-made. Again, in the US, income mobility is very common. Some act like high level earners are just born that way, but studies have shown that a great deal of income mobility exists. I personally know people that have grown up without indoor plumbing, and extremely poor but now earn in the top 5% of wage earners. Quid's points are valid. For example a Starbucks, new I-Phone, and a brake job on your car are somewhat catastrophic if your income is 50K/year, hurts if your income is 100K, and an inconvenience if you make 250K/year.

By investing wisely, planning ahead, budgeting, delaying gratification, finding opportunities, etc... Now if you take those same skills to your workplace isn't it likely you will receive more responsibility, promotions and raises? I believe so. And this too exaggerates the effect on one's net worth. If investing helps you to earn more, then you will have more to invest. To me one of the untold stories of this graph is not just investing, but first building a stable financial base.

I also believe that rate rises are coming in the future, based on the talk from the BofE, so any money I pay off now means guaranteed less interest to pay in the future.

So, in short, I'd follow a plan along these lines of logic. 1) Make sure I have 4-6 months of living expenses as a Rainy Day Fund. Insulate myself from fluctuations in my financial situation. 2) Put away 15% of annual gross income towards \"\"future saving\"\". ISAs first, pension second. 3) Overpay the mortgage and look to remortgage as LTV drops. When LTV nears 60%, look to lock in to a longer-term fix. eg. 2 year fixes at 90% LTV, 5 year fixes at 60%. 4) Reassess steps 2 & 3 as life happens, circumstances change, work fluctuates, etc. 5) Once the mortgage is paid off, build as much wealth as possible - ISAs first, then non-tax efficient savings products.

The first savings goal should be an emergency fund. Think of this not as an investment, but as insurance against life's woes. They happen and having this kind of money earmarked allows one to invest without needing to withdraw at an inopportune time. This should go into a \"\"high interest\"\" savings account or money market account. Figure three to six months of expenses. The next goal should be retirement savings. In the US this is typically done through 401K or if your company does not offer one, either a ROTH IRA or Traditional IRA. The goal should be about 15% of your income. You should favor a 401k match over just about anything else, and then a ROTH over that. The key to transforming from a broke college student into a person with a real job, and disposable income, is a budget. Otherwise you might just end up as a broke person with a real job (not fun). Part of your budget should include savings, spending, and giving. All three areas are the key to building wealth. Once you have all of those taking care of the real fun begins. That is you have an emergency fund, you are putting 15% to retirement, you are spending some on yourself, and giving to a charity of your choice. Then you can dream some with any money left over (after expenses of course). Do you want to retire early? Invest more for retirement. Looking to buy a home or own a bunch of rental property? Start educating yourself and invest for that. Are you passionate about a certain charity? Give more and save some money to take time off in order to volunteer for that charity. All that and more can be yours. Budgeting is a key concept, and the younger you start the easier it gets. While the financiers will disagree with me, you cannot really invest if you are borrowing money. Keep debt to zero or just on a primary residence. I can tell you from personal experience that I did not started building wealth until I made a firm commitment to being out of debt. Buy cars for cash and never pay credit card interest. Pay off student loans as soon as possible. For some reason the idea of giving to charity invokes rancor. A cursory study of millionaires will indicate some surprising facts: most of them are self made, most of them behave differently than pop culture, and among other things most of them are generous givers. Building wealth is about behavior. Giving to charity is part of that behavior. Its my own theory that giving does almost no good for the recipient, but a great amount of good for the giver.

You are right, that having most of one's retirement in one stock or sector is just silly. And again yes, if they're retired, they probably need some bonds. But here's the thing, if they follow your advise and it doesn't work out, it will be a SERIOUS strain on your relationship. Of course you'll still be a family and they'll still love you, but emotionally, you are the reason they lost the money, and that will an elephant in between you. This is especially the case since we're talking about a lot of money here (presumably), and retirement money to boot. You must understand the risk you're taking with your relationships. If you/they lose, at best it'll make things awkward, and you'll feel guilty about their impoverished retirement. At worst it can destroy your relationship with your folks. What about if you win? Won't you be feted and appreciated by your folks for saving them from themselves? Yes, for a short while. Then life moves on. Everything returns to normal. But here's the thing. You won't win. You can't. Because even if you're right here, and they win, that means both they and you will be eager for you to do it again. And at some point they'll take a hit based on your advise. Can I be blunt here? You didn't even know that you can't avoid capital gains taxes by reinvesting stock gains. You don't know enough, and worse, you're not experienced enough. I deduce you're either a college student, or a recent grad. Which means you don't have experience investing your own money. You don't know how the market moves, you just know the theory. You know who you are? You're me, 20 years ago. And thank God my grandparents ignored my advise. I was right about their utilities stocks back then, too. But I know from what I learned in the years afterwards, investing on my own account, that at some point I would have hurt them. And I would have had a very hard time living with that.

The Pathobiological Determinants of Atherosclerosis in Youth Study previously reported risk scores to estimate the probability of advanced atherosclerotic lesions in young individuals aged 15 to 34 years using the coronary heart disease risk factors (gender, age, serum lipoprotein concentrations, smoking, hypertension, obesity, and hyperglycemia). In this study we investigated the relation of these risk scores to the early atherosclerotic lesions. METHODS: We measured atherosclerotic lesions in the left anterior descending coronary artery, right coronary artery, and abdominal aorta and the coronary heart disease risk factors in persons 15 to 34 years of age who died as a result of external causes and were autopsied in forensic laboratories. RESULTS: Risk scores computed from the modifiable risk factors were associated with prevalence of microscopically demonstrable lesions of atherosclerosis (American Heart Association grade 1) in the left anterior descending coronary artery and with the extent of the earliest detectable gross lesion (fatty streaks) in the right coronary artery and abdominal aorta. Risk scores computed from the modifiable risk factors also were associated with prevalence of lesions of higher degrees of microscopic severity (intermediate as well as advanced) in the left anterior descending coronary artery and with extent of lesions of higher degrees of severity (intermediate and raised lesions) in the right coronary artery and abdominal aorta. CONCLUSIONS: Risk scores calculated from traditional coronary heart disease risk factors to identify individual young persons with high probability of having advanced atherosclerotic lesions also are associated with earlier atherosclerotic lesions, including the earliest anatomically demonstrable atherosclerotic lesion.

INTERVENTIONS: A diet containing lean meat (150 g/d) was compared with one with 290 g/d tofu in an isocaloric and isoprotein substitution. Both diet periods were 1 month, and fat intake was carefully controlled. RESULTS: Seven-day diet records showed the two diets were similar in energy, macronutrients and fibre.

RESULTS: Data were available in 1262 patients; mean (SD) age was 61.5 (14.8) years; 47% were women.

DESIGN: Thirty patients with newly diagnosed type 2 diabetes and 30 matched, nondiabetic subjects received the following 3 isoenergetic (780 kcal) meals separated by 1-wk intervals: a high-fat meal; a high-carbohydrate, low-fiber (4.5 g) meal; and a high-carbohydrate, high-fiber meal in which refined-wheat flour was replaced with whole-wheat flour (16.8 g).

RESULTS: Compared with nondiabetic subjects, diabetic patients had higher fasting IL-8 (P < 0.05) and IL-18 (P < 0.01) concentrations and lower adiponectin concentrations (P < 0.01) at baseline. In both nondiabetic and diabetic subjects, IL-18 concentrations increased and adiponectin concentrations decreased (P < 0.05) from baseline concentrations after consumption of the high-fat meal.

Methods Eighty-five obese adults (BMI 30-39.9) were randomly assigned to (127 g) grapefruit (GF), grapefruit juice (GFJ) or water preload for 12 weeks after completing a 2-week caloric restriction phase. Preloads were matched for weight, calories, water content, and energy density. Weekly measures included blood pressure, weight, anthropometry and 24-hour dietary intakes. Resting energy expenditure, body composition, physical performance and cardiometabolic risk biomarkers were assessed. Results The total amount (grams) of food consumed did not change over time. Yet, after preloads were combined with caloric restriction, average dietary energy density and total energy intakes decreased by 20-29% from baseline values. Subjects experienced 7.1% weight loss overall, with significant decreases in percentage body, trunk, android and gynoid fat, as well as waist circumferences (-4.5 cm). However, differences were not statistically significant among groups. Nevertheless, the amount and direction of change in serum HDL-cholesterol levels in GF (+6.2%) and GFJ (+8.2%) preload groups was significantly greater than water preload group (-3.7%). Conclusions These data indicate that incorporating consumption of a low energy dense dietary preload in a caloric restricted diet is a highly effective weight loss strategy. But, the form of the preload did not have differential effects on energy balance, weight loss or body composition. It is notable that subjects in GF and GFJ preload groups experienced significantly greater benefits in lipid profiles.

Flow-mediated dilation of the brachial artery using Doppler ultrasound is a non-invasive technique for the assessment of endothelial function. The objective of the study was to use the above method to evaluate the pathophysiology of high-fat (HF) intake on endothelial function in a local population. A popular local dish \"nasi-lemak\", a source of high saturated fat content from coconut milk, was chosen to represent a local high-fat meal (LHF). In addition, the effects of a Western high-fat (WHF) (\"McDonald's\") meal and a low-fat (LF) meal control on endothelial function were studied. MATERIALS AND METHODS: The study population consisted of 10 healthy male non-smoker (mean age 22 +/- 2 years) with normal body mass index, normal fasting sugar and lipid profiles. Nitric oxide dependent flow-mediated dilation and nitric oxide independent (GTN) dilation was assessed by Doppler flow in the brachial artery before and 4 hours after each meal on separate occasions by 2 experienced sonographers blinded to the type of meals. RESULTS: The baseline brachial artery size, baseline vessel flow and increase in flow after cuff deflation were similar for each of the six arterial studies. In response to reactive hyperaemia after cuff deflation, the endothelium-dependent dilation was significantly different between the meals. There was a marked decrease in endothelium-dependent dilation after the WHF meal compared to the LF meal (8.6 +/- 2.2% vs. -0.8 +/- 1.1%, P < 0.006). There was also a marked decrease in endothelium-dependent dilation after the LHF meal compared to the LF meal (7.7 +/- 2.1% vs. -0.8 +/- 1.1%, P < 0.001). When comparing between the two HF meals, the change in endothelium-dependent dilation was not significant (7.7 vs. 8.6%, P = 0.678). GTN-induced dilation was not significantly different before and after the LF, WHF or LHF (0.1 +/- 0.5% vs. 0.2 +/- 0.9% vs. 1.3 +/- 0.5%, P = 0.094). CONCLUSION: The results suggest that in a local population, impairment of endothelial function is a possible mechanism in the pathophysiology of atherosclerosis from HF intake, beyond just affecting lipid levels. This effect is observed after both a LHF and a WHF meal intake. This technique to study endothelial function may be a useful non-invasive screening tool in the study of other HF diet choices and provides further information for the education of the influence of dietary choices on atherosclerosis.", "title": "Impairment of endothelial function--a possible mechanism for atherosclerosis of a high-fat meal intake." }, { "docid": "MED-2847", "text": "BACKGROUND: Women with gestational diabetes are at increased risk of developing type 2 diabetes, but the risk and time of onset have not been fully quantified. We therefore did a comprehensive systematic review and meta-analysis to assess the strength of association between these conditions and the effect of factors that might modify the risk. METHODS: We identified cohort studies in which women who had developed type 2 diabetes after gestational diabetes were followed up between Jan 1, 1960, and Jan 31, 2009, from Embase and Medline. 205 relevant reports were hand searched. We selected 20 studies that included 675 455 women and 10 859 type 2 diabetic events. We calculated and pooled unadjusted relative risks (RRs) with 95% CIs for each study using a random-effects model. Subgroups analysed were the number of cases of type 2 diabetes, ethnic origin, duration of follow-up, maternal age, body-mass index, and diagnostic criteria. FINDINGS: Women with gestational diabetes had an increased risk of developing type 2 diabetes compared with those who had a normoglycaemic pregnancy (RR 7.43, 95% CI 4.79-11.51). Although the largest study (659 164 women; 9502 cases of type 2 diabetes) had the largest RR (12.6, 95% CI 12.15-13.19), RRs were generally consistent among the subgroups assessed.

METHODS: BCACs (50 mg/day, n = 19) or their placebos (n = 19) were orally administered once daily for a 24-month period. Systemic blood pressure, pulse rates, intraocular pressure (IOP), ocular blood circulation by laser-speckle flowgraphy, and Humphrey visual field mean deviation (MD) were measured during the 24-month period. RESULTS: As a main outcome measurement, we evaluated the difference between the groups in MD deterioration in the eye with a better MD from the trial's baseline through 24 months. A statistically significant difference was observed between the treatment groups in mean change from baseline in MD 24 months after therapy (p = 0.039, unpaired t test).

Objective To examine trends in daily energy intake by children for foods eaten at home or away-from-home, by source of preparation, and for combined categories of eating location and food source. Subjects The analysis uses data from 29,217 children aged 2–18 years from the 1977–1978 Nationwide Food Consumption Survey, 1989–1991 and 1994–1998 Continuing Survey of Food Intake by Individuals, and 2003–2006 National Health and Nutrition Examination Surveys. Methods Nationally representative weighted percentages and means of daily energy intake by eating location were analyzed for trends from 1977 to 2006. Comparisons by food source were examined from 1994 to 2006. Analyses were repeated for 3 age groups: 2–6, 7–12, and 13–18 year olds. Difference testing was conducted using a t test. Results Increased energy intake (+179 kcal/d) by children from 1977–2006 was associated with a major increase in calories eaten away-from-home (+255 kcal/d). The percentage of kcal/d eaten away-from-home increased from 23.4% to 33.9% from 1977–2006. No further increase was observed from 1994–2006, but the sources of calories shifted. The percentage of calories from fast food increased to surpass intake from schools and become the largest contributor to foods prepared away-from-home for all age groups. For foods eaten away-from-home, the percentage of kcal/d from stores increased to become the largest source of calories eaten away-from-home. Fast food eaten at home and store-bought food eaten away-from-home increased significantly. Conclusion Eating location and food source significantly impact daily energy intake for children. Foods prepared away-from-home, including fast food eaten at home and store-prepared food eaten away-from-home, are fueling the increase in total calorie intake.

Objective To examine effects of ALA on cardiovascular responses to acute stress, flow-mediated dilation (FMD) of the brachial artery, and blood concentrations of endothelin-1 and arginine-vasopressin (AVP). Design Using a randomized, crossover study design, cardiovascular responses to acute stress were assessed in 20 hypercholesterolemic subjects, a subset of whom also underwent FMD testing (n = 12). Participants were fed an average American diet (AAD) and 2 experimental diets that varied in the amount of ALA and linoleic acid (LA) that they contained. The AAD provided 8.7% energy from PUFA (7.7% LA, 0.8% ALA). On the LA diet, saturated fat was reduced, and PUFA from walnuts and walnut oil provided 16.4% of energy (12.6% LA, 3.6% ALA).

In the Global Burden of Diseases, Injuries, and Risk Factors Study 2010 (GBD 2010), we aimed to estimate annual deaths for the world and 21 regions between 1980 and 2010 for 235 causes, with uncertainty intervals (UIs), separately by age and sex. METHODS: We attempted to identify all available data on causes of death for 187 countries from 1980 to 2010 from vital registration, verbal autopsy, mortality surveillance, censuses, surveys, hospitals, police records, and mortuaries. We assessed data quality for completeness, diagnostic accuracy, missing data, stochastic variations, and probable causes of death. We applied six different modelling strategies to estimate cause-specific mortality trends depending on the strength of the data. For 133 causes and three special aggregates we used the Cause of Death Ensemble model (CODEm) approach, which uses four families of statistical models testing a large set of different models using different permutations of covariates. Model ensembles were developed from these component models. We assessed model performance with rigorous out-of-sample testing of prediction error and the validity of 95% UIs. For 13 causes with low observed numbers of deaths, we developed negative binomial models with plausible covariates. For 27 causes for which death is rare, we modelled the higher level cause in the cause hierarchy of the GBD 2010 and then allocated deaths across component causes proportionately, estimated from all available data in the database. For selected causes (African trypanosomiasis, congenital syphilis, whooping cough, measles, typhoid and parathyroid, leishmaniasis, acute hepatitis E, and HIV/AIDS), we used natural history models based on information on incidence, prevalence, and case-fatality. We separately estimated cause fractions by aetiology for diarrhoea, lower respiratory infections, and meningitis, as well as disaggregations by subcause for chronic kidney disease, maternal disorders, cirrhosis, and liver cancer. For deaths due to collective violence and natural disasters, we used mortality shock regressions. For every cause, we estimated 95% UIs that captured both parameter estimation uncertainty and uncertainty due to model specification where CODEm was used. We constrained cause-specific fractions within every age-sex group to sum to total mortality based on draws from the uncertainty distributions. FINDINGS: In 2010, there were 52·8 million deaths globally. At the most aggregate level, communicable, maternal, neonatal, and nutritional causes were 24·9% of deaths worldwide in 2010, down from 15·9 million (34·1%) of 46·5 million in 1990. This decrease was largely due to decreases in mortality from diarrhoeal disease (from 2·5 to 1·4 million), lower respiratory infections (from 3·4 to 2·8 million), neonatal disorders (from 3·1 to 2·2 million), measles (from 0·63 to 0·13 million), and tetanus (from 0·27 to 0·06 million). Deaths from HIV/AIDS increased from 0·30 million in 1990 to 1·5 million in 2010, reaching a peak of 1·7 million in 2006. Malaria mortality also rose by an estimated 19·9% since 1990 to 1·17 million deaths in 2010. Tuberculosis killed 1·2 million people in 2010. Deaths from non-communicable diseases rose by just under 8 million between 1990 and 2010, accounting for two of every three deaths (34·5 million) worldwide by 2010. 8 million people died from cancer in 2010, 38% more than two decades ago; of these, 1·5 million (19%) were from trachea, bronchus, and lung cancer. Ischaemic heart disease and stroke collectively killed 12·9 million people in 2010, or one in four deaths worldwide, compared with one in five in 1990; 1·3 million deaths were due to diabetes, twice as many as in 1990. The fraction of global deaths due to injuries (5·1 million deaths) was marginally higher in 2010 (9·6%) compared with two decades earlier (8·8%). This was driven by a 46% rise in deaths worldwide due to road traffic accidents (1·3 million in 2010) and a rise in deaths from falls. Ischaemic heart disease, stroke, chronic obstructive pulmonary disease (COPD), lower respiratory infections, lung cancer, and HIV/AIDS were the leading causes of death in 2010. Ischaemic heart disease, lower respiratory infections, stroke, diarrhoeal disease, malaria, and HIV/AIDS were the leading causes of years of life lost due to premature mortality (YLLs) in 2010, similar to what was estimated for 1990, except for HIV/AIDS and preterm birth complications. YLLs from lower respiratory infections and diarrhoea decreased by 45-54% since 1990; ischaemic heart disease and stroke YLLs increased by 17-28%. Regional variations in leading causes of death were substantial. Communicable, maternal, neonatal, and nutritional causes still accounted for 76% of premature mortality in sub-Saharan Africa in 2010. Age standardised death rates from some key disorders rose (HIV/AIDS, Alzheimer's disease, diabetes mellitus, and chronic kidney disease in particular), but for most diseases, death rates fell in the past two decades; including major vascular diseases, COPD, most forms of cancer, liver cirrhosis, and maternal disorders. For other conditions, notably malaria, prostate cancer, and injuries, little change was noted. INTERPRETATION: Population growth, increased average age of the world's population, and largely decreasing age-specific, sex-specific, and cause-specific death rates combine to drive a broad shift from communicable, maternal, neonatal, and nutritional causes towards non-communicable diseases. Nevertheless, communicable, maternal, neonatal, and nutritional causes remain the dominant causes of YLLs in sub-Saharan Africa. Overlaid on this general pattern of the epidemiological transition, marked regional variation exists in many causes, such as interpersonal violence, suicide, liver cancer, diabetes, cirrhosis, Chagas disease, African trypanosomiasis, melanoma, and others. Regional heterogeneity highlights the importance of sound epidemiological assessments of the causes of death on a regular basis. FUNDING: Bill & Melinda Gates Foundation.

However, results of epidemiologic studies investigating statin use and breast cancer risk have been inconsistent and lacked the ability to evaluate long-term statin use. Materials and Methods We utilized data from a population-based case-control study of breast cancer conducted in the Seattle-Puget Sound region to investigate the relationship between long-term statin use and breast cancer risk. 916 invasive ductal carcinoma (IDC) and 1,068 invasive lobular carcinoma (ILC) cases 55-74 years of age diagnosed between 2000 and 2008 were compared to 902 control women. All participants were interviewed in-person and data on hypercholesterolemia and all episodes of lipid lowering medication use were collected through a structured questionnaire. We assessed the relationship between statin use and IDC and ILC risk using polytomous logistic regression. Results Current users of statins for 10 years or longer had a 1.83-fold increased risk of IDC [95% confidence interval (CI): 1.14-2.93] and a 1.97-fold increased risk of ILC (95% CI: 1.25-3.12) compared to never users of statins. Among women diagnosed with hypercholesterolemia, current users of statins for 10 years or longer had more than double the risk of both IDC [odds ratio (OR): 2.04, 95% CI: 1.17-3.57] and ILC (OR: 2.43, 95% CI: 1.40-4.21) compared to never users.

Objective: We prospectively evaluated the association between postdiagnosis soy food consumption and breast cancer outcomes among US and Chinese women by using data from the After Breast Cancer Pooling Project. Design: The analysis included 9514 breast cancer survivors with a diagnosis of invasive breast cancer between 1991 and 2006 from 2 US cohorts and 1 Chinese cohort. Soy isoflavone intake (mg/d) was measured with validated food-frequency questionnaires. HRs and 95% CIs were estimated by using delayed-entry Cox regression models, adjusted for sociodemographic, clinical, and lifestyle factors. Results: After a mean follow-up of 7.4 y, we identified 1171 total deaths (881 from breast cancer) and 1348 recurrences. Despite large differences in soy isoflavone intake by country, isoflavone consumption was inversely associated with recurrence among both US and Chinese women, regardless of whether data were analyzed separately by country or combined.

Much of the longevity advantage in Okinawa is thought to be related to a healthy lifestyle, particularly the traditional diet, which is low in calories yet nutritionally dense, especially with regard to phytonutrients in the form of antioxidants and flavonoids. Research suggests that diets associated with a reduced risk of chronic diseases are similar to the traditional Okinawan diet, that is, vegetable and fruit heavy (therefore phytonutrient and antioxidant rich) but reduced in meat, refined grains, saturated fat, sugar, salt, and full-fat dairy products. Many of the characteristics of the diet in Okinawa are shared with other healthy dietary patterns, such as the traditional Mediterranean diet or the modern DASH (Dietary Approaches to Stop Hypertension) diet.

The present cross-sectional study included 247 patients. Diet was evaluated by a 3-d food-intake register and reduced to a novel low-carbohydrate diet score (LCDS). Physical examination, demographic, biochemical and anthropometry parameters were recorded, and the saRHI was measured in each patient. Individuals in the lowest LCDS quartile (Q1, 45 % carbohydrate; 20 % protein; 32 % fat) had higher saRHI values than those in the top quartile (Q4, 29 % carbohydrate, 24 % protein, 40 % fat; 1.66 (sd 0.41) v. 1.52 (sd 0.22), P= 0.037). These results were particularly strong in patients with the MS (Q1 = 1.82 (sd 0.32) v. Q4 = 1.61 (sd 027); P= 0.021) and T2D (Q1 = 1.78 (sd 0.31) v. Q4 = 1.62 (sd 0.35); P= 0.011). Multivariate analysis demonstrated that individuals in the highest LCDS quartile had a significantly negative coefficient of saRHI, which was independent of confounders (OR -0.85; 95 % CI 0.19, 0.92; P= 0.031).

We evaluated the long-term effects of consuming a low-calorie low-protein vegan diet or performing regular endurance exercise on cardiometabolic risk factors. METHODS: In this cross-sectional study, cardiometabolic risk factors were evaluated in 21 sedentary subjects, who had been on a low-calorie low-protein raw vegan diet for 4.4 +/- 2.8 years, (mean age, 53.1 +/- 11 yrs), 21 body mass index (BMI)-matched endurance runners consuming Western diets, and 21 age- and gender-matched sedentary subjects, consuming Western diets. RESULTS: BMI was lower in the low-calorie low-protein vegan diet (21.3 +/- 3.1 kg/m(2)) and endurance runner (21.1 +/- 1.6 kg/m(2)) groups than in the sedentary Western diet group (26.5 +/- 2.7 kg/m(2)) (p < 0.005). Plasma concentrations of lipids, lipoproteins, glucose, insulin, C-reactive protein, blood pressure (BP), and carotid artery intima-media thickness were lower in the low-calorie low-protein vegan diet and runner groups than in the Western diet group (all p < 0.05).

At the age of 11 years, endothelium-dependent (flow-mediated) and endothelium-independent (nitrate-mediated) vasodilatory responses of the brachial artery were measured with high-resolution ultrasound in 179 intervention and 190 control children. The effect of intervention on endothelial function was significant in boys (P=0.0034) but not in girls (P=0.69). The maximum endothelium-dependent dilation response (mean+/-SD) was 9.62+/-3.53% and 8.36+/-3.85% in intervention boys and control boys and 8.84+/-4.00% and 8.44+/-3.60% in intervention girls and control girls, respectively.

We investigated whether work-related exhaustion, an indicator of prolonged work stress, is associated with accelerated biological aging, as indicated by shorter leukocyte telomeres, that is, the DNA-protein complexes that cap chromosomal ends in cells. Methods We used data from a representative sample of the Finnish working-age population, the Health 2000 Study. Our sample consisted of 2911 men and women aged 30–64. Work-related exhaustion was assessed using the Maslach Burnout Inventory - General Survey.

Results After adjustment for age and sex, individuals with severe exhaustion had leukocyte telomeres on average 0.043 relative units shorter (standard error of the mean 0.016) than those with no exhaustion (p = 0.009). The association between exhaustion and relative telomere length remained significant after additional adjustment for marital and socioeconomic status, smoking, body mass index, and morbidities (adjusted difference 0.044 relative units, standard error of the mean 0.017, p = 0.008).

Fasting and post-meal blood samples were obtained for 7 h. Large and small triglyceride-rich lipoproteins (TRL), low density (LDL), and high density (HDL) lipoproteins were isolated. Compared to the no-fat, no-cholesterol meal, the fat-enriched meals raised (P < 0.05) plasma triglycerides, phospholipids, and free cholesterol and lowered cholesteryl esters postprandially. The meals containing zero or 140 mg cholesterol generally elicited comparable postprandial plasma and lipoprotein lipid responses. The meals providing 280 or 710 mg cholesterol significantly increased postprandial plasma phospholipids and large TRL triglycerides and decreased plasma esterified cholesterol. The lipid composition of the large TRLs and the concentrations of the small TRL lipid components were not altered postprandially by cholesterol intake. On the other hand, LDL free cholesterol increased after 3 h, LDL cholesteryl esters dropped after 3 and 7 h, HDL cholesteryl esters dropped after 3 h, and HDL phospholipids increased 7 h after ingesting meals highly enriched in cholesterol.

A small protective effect on all-cause and cancer mortality has also been suggested. To examine the association between frequency of nut consumption and mortality in individuals at high cardiovascular risk from Spain, a Mediterranean country with a relatively high average nut intake per person. Methods We evaluated 7,216 men and women aged 55 to 80 years randomized to 1 of 3 interventions (Mediterranean diets supplemented with nuts or olive oil and control diet) in the PREDIMED (‘PREvención con DIeta MEDiterránea’) study. Nut consumption was assessed at baseline and mortality was ascertained by medical records and linkage to the National Death Index. Multivariable-adjusted Cox regression and multivariable analyses with generalized estimating equation models were used to assess the association between yearly repeated measurements of nut consumption and mortality. Results During a median follow-up of 4.8 years, 323 total deaths, 81 cardiovascular deaths and 130 cancer deaths occurred. Nut consumption was associated with a significantly reduced risk of all-cause mortality (P for trend <0.05, all). Compared to non-consumers, subjects consuming nuts >3 servings/week (32% of the cohort) had a 39% lower mortality risk (hazard ratio (HR) 0.61; 95% CI 0.45 to 0.83). A similar protective effect against cardiovascular and cancer mortality was observed. Participants allocated to the Mediterranean diet with nuts group who consumed nuts >3 servings/week at baseline had the lowest total mortality risk (HR 0.37; 95% CI 0.22 to 0.66).

Telomere erosion is a central component of aging, and telomere-associated proteins regulate cellular senescence and survival. This study examines the effects of exercising on vascular telomere biology and endothelial apoptosis in mice and the effects of long-term endurance training on telomere biology in humans. METHODS AND RESULTS: C57/Bl6 mice were randomized to voluntary running or no running wheel conditions for 3 weeks. Exercise upregulated telomerase activity in the thoracic aorta and in circulating mononuclear cells compared with sedentary controls, increased vascular expression of telomere repeat-binding factor 2 and Ku70, and reduced the expression of vascular apoptosis regulators such as cell-cycle-checkpoint kinase 2, p16, and p53. Mice preconditioned by voluntary running exhibited a marked reduction in lipopolysaccharide-induced aortic endothelial apoptosis. Transgenic mouse studies showed that endothelial nitric oxide synthase and telomerase reverse transcriptase synergize to confer endothelial stress resistance after physical activity. To test the significance of these data in humans, telomere biology in circulating leukocytes of young and middle-aged track and field athletes was analyzed. Peripheral blood leukocytes isolated from endurance athletes showed increased telomerase activity, expression of telomere-stabilizing proteins, and downregulation of cell-cycle inhibitors compared with untrained individuals. Long-term endurance training was associated with reduced leukocyte telomere erosion compared with untrained controls.

LF is an uncooked vegan diet and consists of berries, fruits, vegetables and roots, nuts, germinated seeds and sprouts, i.e. rich sources of carotenoids, vitamins C and E. The subjects eating LF showed highly increased levels of beta and alfa carotenes, lycopen and lutein in their sera. Also the increases of vitamin C and vitamin E (adjusted to cholesterol) were statistically significant. As the berry intake was 3-fold compared to controls the intake of polyphenolic compounds like quercetin, myricetin and kaempherol was much higher than in the omnivorous controls. The LF diet is rich in fibre, substrate of lignan production, and the urinary excretion of polyphenols like enterodiol and enterolactone as well as secoisolaricirecinol were much increased in subjects eating LF. The shift of fibromyalgic subjects to LF resulted in a decrease of their joint stiffness and pain as well as an improvement of their self-experienced health. The rheumatoid arthritis patients eating the LF diet also reported similar positive responses and the objective measures supported this finding.

METHODS: The levels of serum LDL cholesterol in 47 subjects with mild to severe (clinical attachment loss equal to or greater than 1 mm) chronic generalized (at least 30% of teeth affected) periodontitis with the mean age of 42.21 ± 1.46 years were measured and compared with those obtained from 42 age (39.83 ± 0.94) and sex matched controls.

All diets were intended to be weight-maintaining (mean intake, 2,577 kcal/d). Compared with the starch-based and low-fat diets, the high-fiber vegetable diet resulted in the largest reduction in low-density lipoprotein (LDL) cholesterol (33% +/- 4%, P <.001) and the greatest fecal bile acid output (1.13 +/- 0.30 g/d, P =.002), fecal bulk (906 +/- 130 g/d, P <.001), and fecal short-chain fatty acid outputs (78 +/- 13 mmol/d, P <.001).

When using the WHO criteria, consistent associations were seen for macrosomia (RR = 1.81; 95%CI 1.47-2.22; p < 0.001); large for gestational age (RR = 1.53; 95%CI 1.39-1.69; p < 0.001); perinatal mortality (RR = 1.55; 95% CI 0.88-2.73; p = 0.13); preeclampsia (RR = 1.69; 95%CI 1.31-2.18; p < 0.001); and cesarean delivery (RR = 1.37;95%CI 1.24-1.51; p < 0.001). Less data were available for the IADPSG criteria, and associations were inconsistent across studies (I2 ≥ 73%). Magnitudes of RRs and their 95%CIs were 1.73 (1.28-2.35; p = 0.001) for large for gestational age; 1.71 (1.38-2.13; p < 0.001) for preeclampsia; and 1.23 (1.01-1.51; p = 0.04) for cesarean delivery. Excluding either the HAPO or the EBDG studies minimally altered these associations, but the RRs seen for the IADPSG criteria were reduced after excluding HAPO. Conclusions The WHO and the IADPSG criteria for GDM identified women at a small increased risk for adverse pregnancy outcomes. Associations were of similar magnitude for both criteria.

MATERIALS AND METHODS: Cardiac and pulmonary 64-detector CT angiography was performed by using current clinical protocols to evaluate the pulmonary veins (electrocardiographically [ECG] gated, 64 sections at 0.625-mm collimation, 120 kVp, 300 mA, 0.35-second tube rotation), native coronary arteries (ECG gated; 64 sections at 0.625 mm; 120 kVp; maximum current, 500-750 mA; minimum, 100-350 mA; 0.35-second tube rotation) and pulmonary embolus (64 sections at 1.25 mm, 140 kVp, 645 mA, 0.5-second tube rotation). Absorbed organ doses were measured by using an anthropomorphic female phantom and metal oxide semiconductor field effect transistor detectors. ED was calculated from measured organ doses and the dose-length product. RESULTS: ED for current adult cardiac and pulmonary 64-detector CT angiography protocols were 12.4-31.8 mSv. Overall, skin, breast, and esophagus and heart had the highest recorded absorbed organ doses. Relative risk for breast cancer incidence for girls and women was 1.004-1.042 for a single examination. Relative risk for lung cancer incidence for men and women was 1.005-1.076 from a single examination. CONCLUSION: EDs and organ doses from 64-detector CT are higher than those previously reported for adult cardiac and pulmonary CT angiography protocols.

An increasing body of research and the 2010 Dietary Guidelines for Americans supports the benefits of a plant-based diet, and legumes specifically, in the reduction of chronic disease risks. The purpose of the current research was to investigate the perception of increased flatulence and gastrointestinal discomfort among participants who consumed a ½ cup of beans daily for 8 or 12 weeks. Methods Participants in three studies to test the effects of beans on heart disease biomarkers completed the same weekly questionnaire to assess gastrointestinal discomfort issues such as increased flatulence, stool changes, and bloating. Studies 1 and 2 were randomized crossover trials. Participants consumed ½ cup of pinto beans, black-eyed peas, and canned carrots as control (n = 17) in Study 1 for three randomized 8-week phases. For Study 2, participants ate ½ cup baked beans or canned carrots as control (n = 29) for two randomized 8-week phases. Study 3 was a parallel arm trial with 40 subjects receiving ½ cup pinto beans and 40 consuming a control soup for 12 weeks. Changes in the frequency of perceived flatulence, stool characteristics, and bloating were the primary outcome measures. Chi-square distributions were examined for the presence or absence of symptoms and demographic characteristics to determine differences by gender, age, body mass index (BMI), and bean type. Results Less than 50% reported increased flatulence from eating pinto or baked beans during the first week of each trial, but only 19% had a flatulence increase with black-eyed peas. A small percentage (3-11%) reported increased flatulence across the three studies even on control diets without flatulence-producing components.

It contains 14 active compounds called monacolins that inhibit hepatic cholesterol synthesis. Although studies have suggested that some formulations of RYR may be effective and safe for lipid lowering, monacolin levels are not standardized among marketed products and are generally not published on labels. We evaluated monacolin levels in 12 commercial RYR formulations and tested for citrinin, a mycotoxin that is nephrotoxic in animals. METHODS: Each formulation of RYR was labeled \"600 mg/capsule\" of active product. Analyses for monacolins and citrinin were performed between August 2006 and June 2008 using high-performance liquid chromatography with mass spectroscopy-mass spectroscopy detection. Laboratory analyses of RYR products were conducted by ConsumerLab.com, White Plains, New York. RESULTS: There was marked variability in the 12 RYR products in total monacolins (0.31-11.15 mg/capsule), monacolin K (lovastatin) (0.10-10.09 mg/capsule), and monacolin KA (0.00-2.30 mg/capsule). Four products had elevated levels of citrinin. CONCLUSIONS: We found striking variability in monacolin content in 12 proprietary RYR products and the presence of citrinin in one-third of the formulations tested. Although RYR may have potential as an alternative lipid-lowering agent, our findings suggest the need for improved standardization of RYR products and product labeling.

Active capsules contained 160 mg of bilberry extract (25-percent anthocyanosides), and the placebo capsules contained only inactive ingredients. Subjects ingested one active or placebo capsule three times daily for 21 days. After the three-week treatment period, a one-month washout period was employed to allow any effect of bilberry on night vision to dissipate.

We investigated the relationship among intestinal microbiota-dependent metabolism of dietary phosphatidylcholine, TMAO levels, and adverse cardiovascular events in humans. METHODS We quantified plasma and urinary levels of TMAO and plasma choline and betaine levels by means of liquid chromatography and online tandem mass spectrometry after a phosphatidylcholine challenge (ingestion of two hard-boiled eggs and deuterium [d9]-labeled phosphatidylcholine) in healthy participants before and after the suppression of intestinal microbiota with oral broad-spectrum antibiotics. We further examined the relationship between fasting plasma levels of TMAO and incident major adverse cardiovascular events (death, myocardial infarction, or stroke) during 3 years of follow-up in 4007 patients undergoing elective coronary angiography. RESULTS Time-dependent increases in levels of both TMAO and its d9 isotopologue, as well as other choline metabolites, were detected after the phosphatidylcholine challenge. Plasma levels of TMAO were markedly suppressed after the administration of antibiotics and then reappeared after withdrawal of antibiotics.

We also performed a case-only survival analysis to examine post-diagnostic consumption of these foods and risk of lethal prostate cancer among the 3,127 men initially diagnosed with non-metastatic prostate cancer during follow-up. In the incidence analysis, we observed 199 events during 306,715 person-years. Men who consumed 2.5 or more eggs per week had an 81% increased risk of lethal prostate cancer compared to men who consumed less than 0.5 eggs per week (HR: 1.81; 95% confidence interval (CI): 1.13, 2.89; p-trend: 0.01). In the case-only survival analysis, we observed 123 events during 19,354 person-years.

Buddhist traditions claim that meditation decreases psychological distress and promotes well-being (e.g., Dalai Lama and Cutler, 2009). Therefore, we investigated the effects of a 3-month meditation retreat on telomerase activity and two major contributors to the experience of stress: Perceived Control (associated with decreased stress) and Neuroticism (associated with increased subjective distress). We used mediation models to test whether changes in Perceived Control and Neuroticism explained meditation retreat effects on telomerase activity. In addition, we investigated whether two qualities developed by meditative practice, increased Mindfulness and Purpose in Life, accounted for retreat-related changes in the two stress-related variables and in telomerase activity. METHODS: Retreat participants (n=30) meditated for ∼6 h daily for 3 months and were compared with a wait-list control group (n=30) matched for age, sex, body mass index, and prior meditation experience. Retreat participants received instruction in concentrative meditation techniques and complementary practices used to cultivate benevolent states of mind (Wallace, 2006). Psychological measures were assessed pre- and post-retreat. Peripheral blood mononuclear cell samples were collected post-retreat for telomerase activity. Because there were clear, a priori hypotheses, 1-tailed significance criteria were used throughout. RESULTS: Telomerase activity was significantly greater in retreat participants than in controls at the end of the retreat (p<0.05). Increases in Perceived Control, decreases in Neuroticism, and increases in both Mindfulness and Purpose in Life were greater in the retreat group (p<0.01). Mediation analyses indicated that the effect of the retreat on telomerase was mediated by increased Perceived Control and decreased Neuroticism. In turn, changes in Perceived Control and Neuroticism were both partially mediated by increased Mindfulness and Purpose in Life. Additionally, increases in Purpose in Life directly mediated the telomerase group difference, whereas increases in Mindfulness did not. CONCLUSIONS: This is the first study to link meditation and positive psychological change with telomerase activity. Although we did not measure baseline telomerase activity, the data suggest that increases in perceived control and decreases in negative affectivity contributed to an increase in telomerase activity, with implications for telomere length and immune cell longevity. Further, Purpose in Life is influenced by meditative practice and directly affects both perceived control and negative emotionality, affecting telomerase activity directly as well as indirectly.

The consequence is an elevated ( > 150 mg/dl) serum total cholesterol level, and the higher the number is above 150, the greater is the quantity of plaque deposited in our arteries. If the serum total cholesterol level can be prevented from rising to more than 150 mg/dl, plaques are not laid down; if elevated levels are lowered to 150 mg/dl, further plaque does not form, and parts of those present may vanish. A fruit-vegetarian-starch diet is necessary as a rule to achieve the 150 mg/dl level in most adults. Lipid-lowering drugs are required in the patients with familial hypercholesterolemia and in most patients with atherosclerotic events.

After purification and fractionation, blueberry anthocyanin extracts (BAE) were yielded with total anthocyanin contents of 31·0 (SD 0·5) % and were used in this study. Replicative senescence of RPE cells was induced by repeatedly passaging cells from the fourth passage to the tenth. From the fifth passage, cultured RPE cells began to enter a replicative senescence, exhibiting reduced cell proliferation along with an increase in the number of β-galactosidase-positive cells. RPE cells maintained high cell viability (P < 0·01) and a low (P < 0·01) percentage of β-galactosidase-positive cells when treated with 0·1 μg/ml BAE.

This paper presents a new concept and comprehensive review of leucine-mediated cell signaling explaining the pathogenesis of T2D and obesity by leucine-induced over-stimulation of mammalian target of rapamycin complex 1 (mTORC1). mTORC1, a pivotal nutrient-sensitive kinase, promotes growth and cell proliferation in response to glucose, energy, growth factors and amino acids. Dairy proteins and meat stimulate insulin/insulin-like growth factor 1 signaling and provide high amounts of leucine, a primary and independent stimulator for mTORC1 activation. The downstream target of mTORC1, the kinase S6K1, induces insulin resistance by phosphorylation of insulin receptor substrate-1, thereby increasing the metabolic burden of β-cells. Moreover, leucine-mediated mTORC1-S6K1-signaling plays an important role in adipogenesis, thus increasing the risk of obesity-mediated insulin resistance. High consumption of leucine-rich proteins explains exaggerated mTORC1-dependent insulin secretion, increased β-cell growth and β-cell proliferation promoting an early onset of replicative β-cell senescence with subsequent β-cell apoptosis. Disturbances of β-cell mass regulation with increased β-cell proliferation and apoptosis as well as insulin resistance are hallmarks of T2D, which are all associated with hyperactivation of mTORC1. In contrast, the anti-diabetic drug metformin antagonizes leucine-mediated mTORC1 signaling. Plant-derived polyphenols and flavonoids are identified as natural inhibitors of mTORC1 and exert anti-diabetic and anti-obesity effects. Furthermore, bariatric surgery in obesity reduces increased plasma levels of leucine and other branched-chain amino acids. Attenuation of leucine-mediated mTORC1 signaling by defining appropriate upper limits of the daily intake of leucine-rich animal and dairy proteins may offer a great chance for the prevention of T2D and obesity, as well as other epidemic diseases of civilization with increased mTORC1 signaling, especially cancer and neurodegenerative diseases, which are frequently associated with T2D.", "title": "Leucine signaling in the pathogenesis of type 2 diabetes and obesity" }, { "docid": "MED-2890", "text": "Myopia is a worldwide public health problem.

Telomere shortness in human beings is emerging as a prognostic marker of disease risk, progression, and premature mortality in many types of cancer, including breast, prostate, colorectal, bladder, head and neck, lung, and renal cell. Telomere shortening is counteracted by the cellular enzyme telomerase. Lifestyle factors known to promote cancer and cardiovascular disease might also adversely affect telomerase function. However, previous studies have not addressed whether improvements in nutrition and lifestyle are associated with increases in telomerase activity. We aimed to assess whether 3 months of intensive lifestyle changes increased telomerase activity in peripheral blood mononuclear cells (PBMC). METHODS: 30 men with biopsy-diagnosed low-risk prostate cancer were asked to make comprehensive lifestyle changes. The primary endpoint was telomerase enzymatic activity per viable cell, measured at baseline and after 3 months. 24 patients had sufficient PBMCs needed for longitudinal analysis. This study is registered on the ClinicalTrials.gov website, number NCT00739791. FINDINGS: PBMC telomerase activity expressed as natural logarithms increased from 2.00 (SD 0.44) to 2.22 (SD 0.49; p=0.031). Raw values of telomerase increased from 8.05 (SD 3.50) standard arbitrary units to 10.38 (SD 6.01) standard arbitrary units.

By application of computational methods for distant homology detection, comparative modeling, and molecular docking, guided by available experimental data, we have generated a three-dimensional structural model of a partial telomerase elongation complex composed of three essential protein domains bound to a single-stranded telomeric DNA sequence in the form of a heteroduplex with the template region of the human RNA subunit, TER. This model provides a structural mechanism for the processivity of telomerase and offers new insights into elongation. We conclude that the RNA∶DNA heteroduplex is constrained by the telomerase TEN domain through repeated extension cycles and that the TEN domain controls the process by moving the template ahead one base at a time by translation and rotation of the double helix. The RNA region directly following the template can bind complementarily to the newly synthesized telomeric DNA, while the template itself is reused in the telomerase active site during the next reaction cycle.

We investigated the effects of berries consumed with WB or RB on postprandial glucose and insulin responses. Healthy females (n = 13-20) participated in 3 randomized, controlled, crossover, 2-h meal studies. They consumed WB or RB, both equal to 50 g available starch, with 150 g whole-berry purée or the same amount of bread without berries as reference. In study 1, WB was served with strawberries, bilberries, or lingonberries and in study 2 with raspberries, cloudberries, or chokeberries. In study 3, WB or RB was served with a mixture of berries consisting of equal amounts of strawberries, bilberries, cranberries, and blackcurrants. Strawberries, bilberries, lingonberries, and chokeberries consumed with WB and the berry mixture consumed with WB or RB significantly reduced the postprandial insulin response. Only strawberries (36%) and the berry mixture (with WB, 38%; with RB, 19%) significantly improved the glycemic profile of the breads. These results suggest than when WB is consumed with berries, less insulin is needed for maintenance of normal or slightly improved postprandial glucose metabolism.

However, the role that beef consumption specifically plays in promoting adverse changes in the cardiovascular risk factor profile is unclear. OBJECTIVE: A meta-analysis of randomized, controlled, clinical trials (RCTs) was conducted to evaluate the effects of beef, independent of other red and processed meats, compared with poultry and/or fish consumption, on lipoprotein lipids. METHODS: RCTs published from 1950 to 2010 were considered for inclusion. Studies were included if they reported fasting lipoprotein lipid changes after beef and poultry/fish consumption by subjects free of chronic disease. A total of 124 RCTs were identified, and 8 studies involving 406 subjects met the prespecified entry criteria and were included in the analysis. RESULTS: Relative to the baseline diet, mean ± standard error changes (in mg/dL) after beef versus poultry/fish consumption, respectively, were -8.1 ± 2.8 vs. -6.2 ± 3.1 for total cholesterol (P = .630), -8.2 ± 4.2 vs. -8.9 ± 4.4 for low-density lipoprotein cholesterol (P = .905), -2.3 ± 1.0 vs. -1.9 ± 0.8 for high-density lipoprotein cholesterol (P = .762), and -8.1 ± 3.6 vs. -12.9 ± 4.0 mg/dL for triacylglycerols (P = .367). CONCLUSION: Changes in the fasting lipid profile were not significantly different with beef consumption compared with those with poultry and/or fish consumption. Inclusion of lean beef in the diet increases the variety of available food choices, which may improve long-term adherence with dietary recommendations for lipid management.

The geographic epidemiology of colorectal cancer seems to correspond to regions with a high rate of beef consumption. Countries with a virtual absence of beef in the diet (India) or where preferably lamb or goat meat is consumed (several Arabic countries) reveal low rates of colorectal cancer.

DESIGN: 6-week, double-blind, randomized, parallel, placebo-controlled trial. SETTING: General community. PARTICIPANTS: 3181 volunteers 2 to 89 years of age. INTERVENTION: Households received identical packages labeled as containing olestra corn or potato chips. These packages contained either olestra or regular chips (control). MEASUREMENT: Gastrointestinal symptoms and their impact on daily activities were reported in a daily record. RESULTS: At least one gastrointestinal symptom was reported by 619 of 1620 (38.2%) persons in the olestra group and 576 of 1561 (36.9%) controls (difference, 1.3 percentage points [95% CI, -3.6 to 6.2 percentage points]; P = 0.60).

METHODS Thirty-nine family dementia caregivers (mean age 60.3 years old (SD=10.2)) were randomized to practicing Kirtan Kriya or listening to relaxation music for 12 minutes per day for eight weeks. The severity of depressive symptoms, mental and cognitive functioning were assessed at baseline and follow-up. Telomerase activity in peripheral blood mononuclear cells (PMBC) was examined in peripheral PBMC pre- and post-intervention. RESULTS The meditation group showed significantly lower levels of depressive symptoms and greater improvement in mental health and cognitive functioning compared to the relaxation group. In the meditation group, 65.2% showed 50% improvement on the Hamilton Depression Rating scale and 52% of the participants showed 50% improvement on the Mental Health Composite Summary score (MCS) of the SF-36 scale; compared to 31.2% and 19% respectively in the relaxation group (pp<0.05). The meditation group showed 43% improvement in telomerase activity compared to 3.7% in the relaxation group (p=0.05).

Nuts have well known cholesterol lowering effects, while evidence is unclear for VOO. We designed a study in hypercholesterolemic patients to assess the effects on serum lipids and other intermediate markers of cardiovascular risk of replacing 40% of the fat in the background diet with VOO, walnuts or almonds. METHODS AND RESULTS: After a 4 week run-in period with a healthy diet, eligible candidates were randomized into three diet sequences in a crossover design, with a common background diet enriched with VOO, walnuts or almonds, lasting 4 weeks each. Outcomes were changes of serum lipids and oxidation and inflammation markers, measured by standard methods. Plasma fatty acids were determined by gas chromatography to assess compliance. In 18 participants completing the study (9 women, mean age 56 y, BMI 25.7 kg/m(2)), LDL-cholesterol was reduced from baseline by 7.3%, 10.8% and 13.4% after the VOO, walnut and almond diets, respectively (P = 0.001, Friedman test). Total cholesterol and LDL/HDL ratios decreased in parallel. LDL-cholesterol decreases were greater than predicted from dietary fatty acid and cholesterol exchanges among diets. No changes of other lipid fractions, oxidation analytes or inflammatory biomarkers were observed. Plasma fatty acid changes after each diet sequence supported good compliance.

However, there is little information on the effects of hazelnut consumption on cardiovascular risk markers. METHODS: The antiatherogenic effect of hazelnut before and after consumption in hypercholesterolemic subjects was investigated. Twenty-one hypercholesterolemic volunteers (18 men and 3 women) were recruited in a double control sandwich model intervention study with a single group and three isoenergetic diet periods. These were control diet I (4 weeks), hazelnut-enriched diet (4 weeks; hazelnut contributing 18%-20% of the total daily energy intake), and control diet period II (4 weeks). The cardiovascular risk biomarkers such as endothelial function, using flow-mediated dilation (FMD) technique, low-density lipoprotein (LDL) oxidation products and inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP), soluble intercellular adhesion molecule-1, and soluble vascular cell adhesion molecule-1 (sVCAM-1) as well as lipids and lipoprotein levels were monitored. RESULTS: Consumption of a hazelnut-enriched diet significantly improved FMD (56.6%), total cholesterol (-7.8%), triacylglycerol (-7.3%), LDL-cholesterol (-6.17%), and high-density lipoprotein cholesterol (6.07%) compared with the control diet I.

The recent recognition of nuts as \"heart-healthy\" foods by the U.S. Food and Drug Administration has given a major boost to the positive image of nuts. Nut consumption has been associated with several health benefits, such as antioxidant, hypocholesterolemic, cardioprotective, anticancer, anti-inflammatory, and antidiabetic benefits, among other functional properties. However, although nuts possess these many health benefits, their consumption has been hampered by a lack of adequate information regarding those benefits.

Through the use of various animal models, it is now well established that by reducing calorie intake one can not only increase life span but, also, lower the risk of various age related diseases such as cancer. Cancer cells are believed to be more dependent on glycolysis for their energy requirements than normal cells and, therefore, can be easily targeted by alteration in the energy-metabolic pathways, a hallmark of CR. Apart from inhibiting the growth of transplantable tumors, CR has been also shown to inhibit the development of spontaneous, radiation, and chemically induced tumors. The question regarding the potentiality of the anti-tumor effect of CR in humans has been in part answered by the resistance of a cohort of women, who had suffered from anorexia in their early life, to breast cancer. However, human research on the beneficial effect of CR is still at an early stage and needs further validation. Though the complete mechanism of the anti-tumor effect of CR is far from clear, the plausible involvement of nutrient sensing pathways or IGF-1 pathways proposed for its anti-aging action cannot be overruled. In fact, cancer cell lines, mutant for proteins involved in IGF-1 pathways, failed to respond to CR. In addition, CR decreases the levels of many growth factors, anabolic hormones, inflammatory cytokines, and oxidative markers that are deregulated in several cancers. In this review, we discuss the anti-tumor effect of CR, describing experiments done in vitro in tumor models and in vivo in mouse models in which the tumor was induced by means of radiation or chemical exposure, expressing oncogenes or deleting tumor suppression genes.

METHODS: The damage mechanisms underlying UV retinal phototoxicity are illustrated with a literature survey and presentation of experimental results. RESULTS: Depending on the wavelength and exposure duration, light interacts with tissue by three general mechanisms: thermal, mechanical, or photochemical. Although the anterior structures of the eye absorb much of the UV component of the optical radiation spectrum, a portion of the UVA band (315-400 nm) penetrates into the retina. Natural sources, such as the sun, emit energetic UV photons in relatively long durations, which typically do not result in energy confinement in the retina, and thus do not produce thermal or mechanical damage but are capable of inducing photochemical damage. Photochemical damage in the retina proceeds through Type 1 (direct reactions involving proton or electron transfers) and Type 2 (reactions involving reactive oxygen species) mechanisms. Commonly used drugs, such as certain antibiotics, nonsteroidal anti-inflammatory drugs, psychotherapeutic agents, and even herbal medicines, may act as photosensitizers that promote retinal UV damage, if they are excited by UVA or visible light and have sufficient retinal penetration.

We examined whether measurement of low-density lipoprotein (LDL) and high-density lipoprotein (HDL) particle subclasses provides additional information relative to CHD risk reduction. METHODS AND RESULTS: This is a prospective nested case-control study of 364 men with a new CHD event (nonfatal myocardial infarction or cardiac death) during a 5.1-year (median) follow-up and 697 age-matched controls. Nuclear magnetic resonance (NMR) spectroscopy was used to quantify levels of LDL and HDL particle subclasses and mean particle sizes in plasma obtained at baseline and after 7 months of treatment with gemfibrozil or placebo. Odds ratios for a 1-SD increment of each lipoprotein variable were calculated with adjusted logistic regression models. Gemfibrozil treatment increased LDL size and lowered numbers of LDL particles (-5%) while raising numbers of HDL particles (10%) and small HDL subclass particles (21%). Concentrations of these LDL and HDL particles achieved with gemfibrozil were significant, independent predictors of new CHD events.

However, there is also a widely perceived view that eating nuts can lead to body weight gain due to their high fat content. Purpose To investigate the impact of different dosages of pistachios on body weight, blood pressure, blood lipids, blood glucose and insulin in subjects with metabolic syndrome. Methods Ninety subjects with metabolic syndrome (consistent with 2005 International Diabetes Federation metabolic syndrome standard without diabetes) were enrolled in three endocrinology outpatient clinics in Beijing. All subjects received dietary counseling according to the guidelines of the American Heart Association Step I diet. After a 4 week run-in, subjects were randomized to consume either the recommended daily serving of 42 g pistachios (RSG), a higher daily serving of 70 g pistachio (HSG) or no pistachios (DCG) for 12 weeks. Results Subjects in all three groups were matched at baseline for BMI: DCG 28.03 ± 4.3; RSG 28.12 ± 3.22; and HSG 28.01 ± 4.51 kg/m2. There were no significant changes in body weight or BMI in any groups during the study nor any change from baseline at any time point in any group. During the entire study, there were no significant differences in waist-to-hip ratio among the groups or any change from baseline in any group (DCG -0.00 ± 0.03, RSG -0.01 ± 0.02 and HSG 0.01 ± 0.04). There were no significant differences detected among groups in triglycerides, fasting glucose and 2 hour postprandial glucose following a 75 gram glucose challenge. Exploratory analyses demonstrated that glucose values 2 h after a 75 gm glucose challenge were significantly lower at week 12 compared with baseline values in the HSG group (-1.13 ± 2.58 mmol/L, p = 0.02), and a similar trend was noted in the RSG group (-0.77 ± 2.07 mmol/L, p = 0.06), while no significant change was seen in the DCG group (-0.15 ± 2.27 mmol/L, p = 0.530).

The study subjects were thirteen healthy volunteers with a mean (± SD) age of 40.2 ± 6.7 years and ten participants with type 2 diabetes mellitus (controlled on lifestyle measures and/or metformin) with a mean HbA1c (± SD) of 6.6 ± (0.7%) and a mean age (± SD) of 40.8 ± 5.7 years. Each subject was tested on eight separate days with 50 g of glucose (on 3 occasions) and 50 g equivalent of available carbohydrates from the 5 varieties of date (each on one occasion). Capillary glucose was measured in the healthy subjects at 0, 15, 30, 45, 60, 90 and 120 min and for the diabetics at 0, 30, 60, 90, 120, 150 and 180 min.

RESULTS: We documented 758 incident cases of GDM. After adjustment for age, parity, pre-pregnancy BMI and other covariates, the relative risk (RR) of GDM, comparing the highest with the lowest quintile of the Western pattern scores, was 1.63 (95% CI 1.20-2.21; p (trend)=0.001), whereas the RR comparing the lowest with the highest quintile of the prudent pattern scores was 1.39 (95% CI 1.08-1.80; p (trend)=0.018).

INTERVENTION: Two portions per day of whole-grain RTE oat cereal (3 g/day oat b-glucan) or energy-matched low-fiber foods (control), as part of a reduced energy ( approximately 500 kcal/day deficit) dietary program that encouraged limiting consumption of foods high in energy and fat, portion control, and regular physical activity. MAIN OUTCOME MEASURES: Fasting lipoprotein levels, waist circumference, triceps skinfold thickness, and body weight were measured at baseline and weeks 4, 8, 10, and 12. RESULTS: LDL cholesterol level was reduced significantly more with whole-grain RTE oat cereal vs control (-8.7+/-1.0 vs -4.3+/-1.1%, P=0.005). Total cholesterol (-5.4+/-0.8 vs -2.9+/-0.9%, P=0.038) and non-high-density lipoprotein-cholesterol (-6.3+/-1.0 vs -3.3+/-1.1%, P=0.046) were also lowered significantly more with whole-grain RTE oat cereal, whereas high-density lipoprotein and triglyceride responses did not differ between groups. Weight loss was not different between groups (-2.2+/-0.3 vs -1.7+/-0.3 kg, P=0.325), but waist circumference decreased more (-3.3+/-0.4 vs -1.9+/-0.4 cm, P=0.012) with whole-grain RTE oat cereal. Larger reductions in LDL, total, and non-high-density lipoprotein cholesterol levels and waist circumference were evident as early as week 4 in the whole-grain RTE oat cereal group. CONCLUSIONS: Consumption of a whole-grain RTE oat cereal as part of a dietary program for weight loss had favorable effects on fasting lipid levels and waist circumference.

We assessed the epidemiology of Alzheimer's disease and other forms of dementia in China between 1990, and 2010, to improve estimates of the burden of disease, analyse time trends, and inform health policy decisions relevant to China's rapidly ageing population. METHODS: In our systematic review we searched for reports of Alzheimer's disease or dementia in China, published in Chinese and English between 1990 and 2010. We searched China National Knowledge Infrastructure, Wanfang, and PubMed databases. Two investigators independently assessed case definitions of Alzheimer's disease and dementia: we excluded studies that did not use internationally accepted case definitions. We also excluded reviews and viewpoints, studies with no numerical estimates, and studies not done in mainland China. We used Poisson regression and UN demographic data to estimate the prevalence (in nine age groups), incidence, and standardised mortality ratio of dementia and its subtypes in China in 1990, 2000, and 2010. FINDINGS: Our search returned 12,642 reports, of which 89 met the inclusion criteria (75 assessed prevalence, 13 incidence, and nine mortality). In total, the included studies had 340,247 participants, in which 6357 cases of Alzheimer's disease were recorded. 254,367 people were assessed for other forms of dementia, of whom 3543 had vascular dementia, frontotemporal dementia, or Lewy body dementia. In 1990 the prevalence of all forms of dementia was 1·8% (95% CI 0·0-44·4) at 65-69 years, and 42·1% (0·0-88·9) at age 95-99 years. In 2010 prevalence was 2·6% (0·0-28·2) at age 65-69 years and 60·5% (39·7-81·3) at age 95-99 years. The number of people with dementia in China was 3·68 million (95% CI 2·22-5·14) in 1990, 5·62 million (4·42-6·82) in 2000, and 9·19 million (5·92-12·48) in 2010. In the same period, the number of people with Alzheimer's disease was 1·93 million (1·15-2·71) in 1990, 3·71 million (2·84-4·58) people in 2000, and 5·69 million (3·85-7·53) in 2010. The incidence of dementia was 9·87 cases per 1000 person-years, that of Alzheimer's disease was 6·25 cases per 1000 person-years, that of vascular dementia was 2·42 cases per 1000 person-years, and that of other rare forms of dementia was 0·46 cases per 1000 person-years. We retrieved mortality data for 1032 people with dementia and 20,157 healthy controls, who were followed up for 3-7 years. The median standardised mortality ratio was 1·94:1 (IQR 1·74-2·45). INTERPRETATION: Our analysis suggests that previous estimates of dementia burden, based on smaller datasets, might have underestimated the burden of dementia in China. The burden of dementia seems to be increasing faster than is generally assumed by the international health community. Rapid and effective government responses are needed to tackle dementia in low-income and middle-income countries.

The serum total cholesterol of subjects differed and ranged from 259 to 283 mg/dL. The study was conducted in a double-blind randomized crossover design on a 14-week period, consisting of four 2-week experimental periods, with each experimental period separated by a 2-week washout period. The test foods were as follows: corn flakes as the control food, oat bran flakes as the reference food, and corn flakes with 15% and 25% dietary fiber from coconut flakes (made from coconut flour production). Results showed a significant percent reduction in serum total and low-density lipoprotein (LDL) cholesterol (in mg/dL) for all test foods, except for corn flakes, as follows: oat bran flakes, 8.4 +/- 1.4 and 8.8 +/- 6.0, respectively; 15% coconut flakes, 6.9 +/- 1.1 and 11.0 +/- 4.0, respectively; and 25% coconut flakes, 10.8 +/- 1.3 and 9.2 +/- 5.4, respectively. Serum triglycerides were significantly reduced for all test foods: corn flakes, 14.5 +/- 6.3%; oat bran flakes, 22.7 +/- 2.9%; 15% coconut flakes, 19.3 +/- 5.7%; and 25% coconut flakes, 21.8 +/- 6.0%.

In general, DR has less effect in extending lifespan in males and also in non-model organisms.

Dental diseases impact considerably on self-esteem and quality of life and are expensive to treat. The objective of this paper is to review the evidence for an association between nutrition, diet and dental diseases and to present dietary recommendations for their prevention. Nutrition affects the teeth during development and malnutrition may exacerbate periodontal and oral infectious diseases. However, the most significant effect of nutrition on teeth is the local action of diet in the mouth on the development of dental caries and enamel erosion. Dental erosion is increasing and is associated with dietary acids, a major source of which is soft drinks. Despite improved trends in levels of dental caries in developed countries, dental caries remains prevalent and is increasing in some developing countries undergoing nutrition transition. There is convincing evidence, collectively from human intervention studies, epidemiological studies, animal studies and experimental studies, for an association between the amount and frequency of free sugars intake and dental caries. Although other fermentable carbohydrates may not be totally blameless, epidemiological studies show that consumption of starchy staple foods and fresh fruit are associated with low levels of dental caries. Fluoride reduces caries risk but has not eliminated dental caries and many countries do not have adequate exposure to fluoride. It is important that countries with a low intake of free sugars do not increase intake, as the available evidence shows that when free sugars consumption is <15-20 kg/yr ( approximately 6-10% energy intake), dental caries is low. For countries with high consumption levels it is recommended that national health authorities and decision-makers formulate country-specific and community-specific goals for reducing the amount of free sugars aiming towards the recommended maximum of no more than 10% of energy intake. In addition, the frequency of consumption of foods containing free sugars should be limited to a maximum of 4 times per day.

Reactive oxygen species (ROS) are generated in response to both endogenous and exogenous stimuli. To counterbalance ROS-mediated injury, an endogenous antioxidants defense system exists; however, when oxidation exceeds the control mechanisms, oxidative stress arises. Chronic and cumulative oxidative stress induces deleterious modifications to a variety of macromolecular components, such as DNA, lipids, and proteins. A primary mechanism of many chemotherapy drugs against cancer cells is the formation of ROS, or free radicals. Radiotherapy is based on the fact that ionizing radiation destroys tumor cells. Radiotherapy induces direct lesions in the DNA or biological molecules, which eventually affect DNA. Free radicals produced by oncology therapy are often a source of serious side effects as well.

A total of 41 randomized controlled trials in which isolated soy protein supplementation was the only intervention and the net changes in serum lipids during intervention were reported. Information on study design, sample size, participant characteristics, intervention, follow-up duration, and treatment outcomes was independently abstracted using a standardized protocol. Using a random-effects model, data from each study were pooled and weighted by the inverse of their variance. Soy protein supplementation was associated with a significant reduction in mean serum total cholesterol (-5.26 mg/dl, 95% confidence interval [CI] -7.14 to -3.38), low-density lipoprotein cholesterol (-4.25 mg/dl, 95% CI -6.00 to -2.50), and triglycerides (-6.26 mg/dl, 95% CI -9.14 to -3.38) and a significant increase in high-density lipoprotein cholesterol (0.77 mg/dl, 95% CI 0.20 to 1.34). Meta-regression analyses showed a dose-response relation between soy protein and isoflavone supplementation and net changes in serum lipids. These results indicate that soy protein supplementation reduces serum lipids among adults with or without hypercholesterolemia.

Therefore, we studied lipid storage functions in these cells. Both triacylglycerol and cholesteryl ester (CE) concentrations were higher in the ER(-) cells, but the ability to synthesize CE distinguished the two types of breast cancer cells. Higher baseline, oleic acid- and LDL-stimulated CE concentrations were found in ER(-) compared to ER(+) cells.

Human LDL stimulated proliferation of ER(-) MDA-MB-231 cells, but had little effect on proliferation of ER(+) MCF-7 cells. The functional significance of these findings was demonstrated by the observation that the ACAT inhibitor CP-113,818 reduced proliferation of breast cancer cells, and specifically reduced LDL-induced proliferation of ER(-) cells.

MEASUREMENTS: Dental and physical examinations were conducted every 3 to 5 years. Diet was assessed using food frequency questionnaires (FFQs). Mean follow-up was 15 years (range: 2-24 years). Periodontal disease progression on each tooth was defined as alveolar bone loss (ABL) advancement of 40% or more, probing pocket depth (PPD) of 2 mm or more, or tooth loss. Good and excellent fiber sources provided 2.5 g or more of fiber per serving. Multivariate proportional hazards regression estimated hazard ratios (HRs) and 95% confidence intervals (CIs) of periodontal disease progression and tooth loss in relation to fiber sources, stratified according to age younger than 65 versus 65 and older, and controlled for smoking, body mass index, calculus, baseline periodontal disease level, caries, education, exercise, carotene, thiamin and caffeine intake, and tooth brushing. RESULTS: In men aged 65 and older, each serving of good to excellent sources of total fiber was associated with lower risk of ABL progression (HR = 0.76, 95% CI = 0.60-0.95) and tooth loss (HR = 0.72, 95% CI = 0.53-0.97).

METHODS: This study used two approaches to see whether dietary or other changes could explain AD trends in Japan and developing countries. One approach involved comparing trends of AD in Japan with changes in national dietary supply factors, alcohol consumption, and lung cancer mortality rates from zero to 25 years before the prevalence data. The second compared AD prevalence values for eight developing countries with dietary supply factors from zero to 25 years before the prevalence data. RESULTS: For Japan, alcohol consumption, animal product, meat and rice supply, and lung cancer rates correlated highly with AD prevalence data, with the strongest correlation for a lag of 15-25 years. In the eight-country study, total energy and animal fat correlated highly with AD prevalence data, with a lag of 15-20 years. Mechanisms to explain the findings include increased obesity for the eight countries, and increases in cholesterol, saturated fat, and iron from increases in animal products and meat supply for Japan.

In this paper we review the role of nutrients, foods, particularly nuts, and dietary patterns on BP control. DATA SYNTHESIS: Because nuts are low in sodium and contain significant amounts of mono- and polyunsaturated fatty acids, fiber, minerals such as magnesium, potassium and calcium, and antioxidants, they have been suggested as potentially protective foods against hypertension. Limited evidence from prospective studies and clinical trials suggests that nut consumption has a beneficial effect on both BP and EF. However, BP changes were a secondary outcome in nut feeding trials and no study used ambulatory BP monitoring as the standard for BP measurements.

It is increasingly believed that consumption of dietary cholesterol and egg yolks is harmless. There are good reasons for long-standing recommendations that dietary cholesterol should be limited to less than 200 mg/day; a single large egg yolk contains approximately 275 mg of cholesterol (more than a day’s worth of cholesterol). Although some studies showed no harm from consumption of eggs in healthy people, this outcome may have been due to lack of power to detect clinically relevant increases in a low-risk population. Moreover, the same studies showed that among participants who became diabetic during observation, consumption of one egg a day doubled their risk compared with less than one egg a week. Diet is not just about fasting cholesterol; it is mainly about the postprandial effects of cholesterol, saturated fats, oxidative stress and inflammation. A misplaced focus on fasting lipids obscures three key issues. Dietary cholesterol increases the susceptibility of low-density lipoprotein to oxidation, increases postprandial lipemia and potentiates the adverse effects of dietary saturated fat. Dietary cholesterol, including egg yolks, is harmful to the arteries. Patients at risk of cardiovascular disease should limit their intake of cholesterol. Stopping the consumption of egg yolks after a stroke or myocardial infarction would be like quitting smoking after a diagnosis of lung cancer: a necessary action, but late. The evidence presented in the current review suggests that the widespread perception among the public and health care professionals that dietary cholesterol is benign is misplaced, and that improved education is needed to correct this misconception. Résumé Une idée fausse et généralisée se répand au sein du public canadien et des médecins, qui pensent de plus en plus que la consommation de cholestérol alimentaire et de jaunes d’œuf est inoffensive. Les recommandations de longue date qui préconisent de limiter le cholestérol alimentaire à moins de 200 mg/jour reposent sur de bonnes raisons. Un seul gros jaune d’œuf contient environ 275 mg de cholestérol (plus que la portion quotidienne de cholestérol). Même si certaines études ont démontré que la consommation d’œufs n’est pas nuisible chez les personnes en santé, ce résultat peut découler de l’absence de capacité à déceler des augmentations pertinentes sur le plan clinique au sein d’une population à faible risque. De plus, les mêmes études ont révélé que chez les participants devenus diabétiques pendant la période d’observation, la consommation d’un œuf par jour doublait leur risque par rapport à la consommation de moins d’un œuf par semaine.

The investigators compared the increase in relative risk for cardiovascular disease associated with the total fat and trans fat content of fast foods against the relative risk decrease provided by daily statin consumption from a meta-analysis of statins in primary prevention of coronary artery disease (7 randomized controlled trials including 42,848 patients). The risk reduction associated with the daily consumption of most statins, with the exception of pravastatin, is more powerful than the risk increase caused by the daily extra fat intake associated with a 7-oz hamburger (Quarter Pounder) with cheese and a small milkshake. In conclusion, statin therapy can neutralize the cardiovascular risk caused by harmful diet choices. In other spheres of human activity, individuals choosing risky pursuits (motorcycling, smoking, driving) are advised or compelled to use measures to minimize the risk (safety equipment, filters, seatbelts).

However, after the onset of menopause, the risk of cardiovascular disease increases drastically due to ovarian hormone deficiency. Hence, we conducted a 1-year clinical trial to evaluate the effect of dried apple vs dried plum consumption in reducing cardiovascular disease risk factors in postmenopausal women. DESIGN: One-hundred sixty qualified postmenopausal women were recruited from the greater Tallahassee, FL, area during 2007-2009 and were randomly assigned to one of two groups: dried apple (75 g/day) or dried plum (comparative control). Fasting blood samples were collected at baseline, 3, 6, and 12 months to measure various parameters. Physical activity recall and 7-day dietary recall were also obtained. RESULTS: Neither of the dried fruit regimens significantly affected the participants' reported total energy intake throughout the study period. On the contrary, women who consumed dried apple lost 1.5 kg body weight by the end of the study, albeit not significantly different from the dried plum group. In terms of cholesterol, serum total cholesterol levels were significantly lower in the dried apple group compared with the dried plum group only at 6 months. Although dried plum consumption did not significantly reduce serum total cholesterol and low-density lipoprotein cholesterol levels, it lowered their levels numerically by 3.5% and 8%, respectively, at 12 months compared with baseline. This may explain the lack of significance observed between the groups. However, within the group, women who consumed dried apple had significantly lower serum levels of total cholesterol and low-density lipoprotein cholesterol by 9% and 16%, respectively, at 3 months compared with baseline. These serum values were further decreased to 13% and 24%, respectively, after 6 months but stayed constant thereafter. The within-group analysis also reported that daily apple consumption profoundly improved atherogenic risk ratios, whereas there were no significant changes in lipid profile or atherogenic risk ratios as a result of dried plum consumption. Both dried fruits were able to lower serum levels of lipid hydroperoxide and C-reactive protein. However, serum C-reactive protein levels were significantly lower in the dried plum group compared with the dried apple group at 3 months. CONCLUSIONS: There were no significant differences between the dried apple and dried plum groups in altering serum levels of atherogenic cholesterols except total cholesterol at 6 months.

BACKGROUND: Observational studies suggest an association between ED and the incidence of CVD. However, whether ED is an independent risk factor of CVD remains controversial. METHODS: The PubMed database was searched through January 2011 to identify studies that met pre-stated inclusion criteria. Reference lists of retrieved articles were also reviewed. Two authors independently extracted information on the designs of the studies, the characteristics of the study participants, exposure and outcome assessments, and control for potential confounding factors. Either a fixed- or a random-effects model was used to calculate the overall combined risk estimates. RESULTS: Twelve prospective cohort studies involving 36,744 participants were included in the meta-analysis. The overall combined relative risks for men with ED compared with the reference group were 1.48 (95% confidence interval [CI]: 1.25 to 1.74) for CVD, 1.46 (95% CI: 1.31 to 1.63) for coronary heart disease, 1.35 (95% CI: 1.19 to 1.54) for stroke, and 1.19 (95% CI: 1.05 to 1.34) for all-cause mortality. Sensitivity analysis restricted to studies with control for conventional cardiovascular risk factors yielded similar results. No evidence of publication bias was observed. CONCLUSIONS: This meta-analysis of prospective cohort studies suggests that ED significantly increases the risk of CVD, coronary heart disease, stroke, and all-cause mortality, and the increase is probably independent of conventional cardiovascular risk factors.

Materials and METHODS: This review summarizes the current epidemiological and clinical trial evidence relating diet to breast cancer incidence, recurrence, survival, and mortality. The review includes emerging epidemiological studies that assess risk within breast cancer subtypes as well as a summary of previous and ongoing dietary intervention trials designed to modify breast cancer risk. RESULTS: The available literature suggests that both low-fat and high-fiber diets may be weakly protective against breast cancer, whereas total energy intake and alcohol appear to be positively associated. Fiber may be weakly protective possibly through modulation of estrogen, whereas fruit and vegetable intake is not clearly associated with risk. Obesity is a risk factor for postmenopausal disease, and adult weight gain should be avoided to reduce risk. In survivors, diet has the greatest potential influence on overall mortality rather than breast cancer-specific events.

RESULTS During 3,038,853 person-years of follow-up, 16,200 women and 11,229 men died. Nut consumption was inversely associated with total mortality among both women and men, after adjustment for other known or suspected risk factors. The pooled multivariate hazard ratios for death among participants who ate nuts, as compared with those who did not, were 0.93 (95% confidence interval [CI], 0.90 to 0.96) for the consumption of nuts less than once per week, 0.89 (95% CI, 0.86 to 0.93) for once per week, 0.87 (95% CI, 0.83 to 0.90) for two to four times per week, 0.85 (95% CI, 0.79 to 0.91) for five or six times per week, and 0.80 (95% CI, 0.73 to 0.86) for seven or more times per week (P<0.001 for trend).

The purpose of this study was to evaluate the effects of daily supplementation with a proprietary milk-based formulation of goji berry, Lacto-Wolfberry (LWB), on macular characteristics and plasma zeaxanthin and antioxidant capacity levels in elderly subjects. METHODS: This was a double-masked, randomized, placebo-controlled trial in healthy elderly subjects (range, 65 to 70 years) receiving 13.7 g/d of LWB (n = 75) or placebo (n = 75) for 90 days.

OBJECTIVES: To measure the burden of diseases, injuries, and leading risk factors in the United States from 1990 to 2010 and to compare these measurements with those of the 34 countries in the Organisation for Economic Co-operation and Development (OECD) countries. DESIGN: We used the systematic analysis of descriptive epidemiology of 291 diseases and injuries, 1160 sequelae of these diseases and injuries, and 67 risk factors or clusters of risk factors from 1990 to 2010 for 187 countries developed for the Global Burden of Disease 2010 Study to describe the health status of the United States and to compare US health outcomes with those of 34 OECD countries. Years of life lost due to premature mortality (YLLs) were computed by multiplying the number of deaths at each age by a reference life expectancy at that age. Years lived with disability (YLDs) were calculated by multiplying prevalence (based on systematic reviews) by the disability weight (based on population-based surveys) for each sequela; disability in this study refers to any short- or long-term loss of health. Disability-adjusted life-years (DALYs) were estimated as the sum of YLDs and YLLs. Deaths and DALYs related to risk factors were based on systematic reviews and meta-analyses of exposure data and relative risks for risk-outcome pairs. Healthy life expectancy (HALE) was used to summarize overall population health, accounting for both length of life and levels of ill health experienced at different ages. RESULTS: US life expectancy for both sexes combined increased from 75.2 years in 1990 to 78.2 years in 2010; during the same period, HALE increased from 65.8 years to 68.1 years. The diseases and injuries with the largest number of YLLs in 2010 were ischemic heart disease, lung cancer, stroke, chronic obstructive pulmonary disease, and road injury. Age-standardized YLL rates increased for Alzheimer disease, drug use disorders, chronic kidney disease, kidney cancer, and falls. The diseases with the largest number of YLDs in 2010 were low back pain, major depressive disorder, other musculoskeletal disorders, neck pain, and anxiety disorders. As the US population has aged, YLDs have comprised a larger share of DALYs than have YLLs. The leading risk factors related to DALYs were dietary risks, tobacco smoking, high body mass index, high blood pressure, high fasting plasma glucose, physical inactivity, and alcohol use. Among 34 OECD countries between 1990 and 2010, the US rank for the age-standardized death rate changed from 18th to 27th, for the age-standardized YLL rate from 23rd to 28th, for the age-standardized YLD rate from 5th to 6th, for life expectancy at birth from 20th to 27th, and for HALE from 14th to 26th. CONCLUSIONS AND RELEVANCE: From 1990 to 2010, the United States made substantial progress in improving health. Life expectancy at birth and HALE increased, all-cause death rates at all ages decreased, and age-specific rates of years lived with disability remained stable.

Literature search, data extraction and study quality assessment were performed independently by two reviewers and results were pooled quantitatively using meta-analysis methods.

The pooled relative risk (RR) for early AMD, comparing the highest with the lowest category of lutein and zeaxanthin intake, was 0·96 (95 % CI 0·78, 1·17). Dietary intake of these carotenoids was significantly related with a reduction in risk of late AMD (RR 0·74; 95 % CI 0·57, 0·97); and a statistically significant inverse association was observed between lutein and zeaxanthin intake and neovascular AMD risk (RR 0·68; 95 % CI 0·51, 0·92).

These benefits may be mediated, at least in part, by down-regulated activity of the mTORC1 complex, a key regulator of protein translation. By boosting the effective availability of the translation initiator eIF4E, mTORC1 activity promotes the translation of a number of \"weak\" mRNAs that code for proteins, often up-regulated in cancer, that promote cellular proliferation, invasiveness, and angiogenesis, and that abet cancer promotion and chemoresistance by opposing apoptosis. Measures which inhibit eIF4E activity, either directly or indirectly, may have utility not only for cancer prevention, but also for the treatment of many cancers in which eIF4E drives malignancy. Since eIF4E is overexpressed in many cancers, strategies which target eIF4E directly--some of which are now being assessed clinically--may have the broadest efficacy in this regard. Many of the \"weak\" mRNAs coding for proteins that promote malignant behavior or chemoresistance are regulated transcriptionally by NF-kappaB and/or Stat3, which are active in a high proportion of cancers; thus, regimens concurrently targeting eIF4E, NF-kappaB, and Stat3 may suppress these proteins at both the transcriptional and translational levels, potentially achieving a very marked reduction in their expression.

DR is often referred to as calorie restriction, implying that reduced energy intake is responsible for its widespread and evolutionarily conserved benefits. However, recent data indicate dietary amino acid restriction as a key mediator of DR benefits. In fruitflies, an imbalance in essential amino acid intake is thought to underlie longevity benefits of DR. In mammals, reduced dietary protein or essential amino acid intake can extend longevity, improve metabolic fitness and increase stress resistance. In the present paper we review two evolutionarily conserved signal transduction pathways responsible for sensing amino acid levels. The eIF2α (eukaryotic initiation factor 2α) kinase GCN2 (general amino acid control non-derepressible 2) senses the absence of one or more amino acids by virtue of direct binding to uncharged cognate tRNAs. The presence of certain amino acids, such as leucine, permits activation of the master growth regulating kinase TOR (target of rapamycin). These two signal transduction pathways react to amino acid deprivation by inhibiting general protein translation while at the same time increasing translation of specific mRNAs involved in restoring homoeostasis. Together, these pathways may contribute to the regulation of longevity, metabolic fitness and stress resistance.", "title": "Amino acid sensing in dietary-restriction-mediated longevity: roles of signal-transducing kinases GCN2 and TOR" }, { "docid": "MED-1914", "text": "How can adverse experiences in early life, such as maltreatment, exert such powerful negative effects on health decades later?

Methods: Relevant articles were obtained through a review of the medical literature and the strength of the available evidence was graded according to the American Academy of Neurology evidence classification scheme. Results: The accumulated Class III and IV evidence suggests an increased incidence of systolic dysfunction and therapy-related acute leukemia (TRAL) with mitoxantrone therapy. Systolic dysfunction occurs in ∼12% of patients with MS treated with mitoxantrone, congestive heart failure occurs in ∼0.4%, and leukemia occurs in ∼0.8%. The number needed to harm is 8 for systolic dysfunction and 123 for TRAL. There is no new efficacy evidence that would change the recommendation from the previous report.

In senescent cells, the fatty acid composition of the cellular membranes alters and leads to changes in both structure and function of organelles, especially mitochondria. Animal models of accelerated aging exhibit repression of stearoyl-CoA desaturase activity while anti-aging calorie restriction stimulates the same enzyme system. It is concluded that aging in cells and whole organisms share a common initiation pathway and that cellular senescence is protective against cancer.

A low concordance rate of insulin-dependent diabetes mellitus among monozygotic twins clearly indicates that genetic risk factors may be necessary, but are not sufficient for the disease to occur. The strongest genetic risk markers are located in the HLA region of chromosome 6, but these DNA specificities differ in different populations. Risk genes are indicated in other chromosomes of the human genome, suggesting a complex interaction between genes and environment as the cause of the disease. The pathogenesis of the disease is proposed to be autoimmune in nature and environmental risk factors may either initiate autoimmunity or accelerate an already ongoing beta-cell destruction. Risk factors disclosed by epidemiological studies that may accelerate the pathogenetic process are: a cold environment, a high growth rate, infections and stressful life events. Risk factors that may initiate the autoimmune process include early exposure to cow's milk proteins, nitrosamines or early foetal events such as blood group incompatibility or foetal viral infections.

AIMS: To explore the many questions regarding barriers to, and motivators for, cholesterol-lowering diet adherence. METHODS: We surveyed French general practitioners' dietetic practices for patients with hypercholesterolaemia, and looked at their patients' attitudes towards such an approach. RESULTS: We analysed 234 doctors' personal questionnaires and 356 patient self-survey questionnaires. Patients' reasons for not complying with the prescribed diet included: 'already having satisfactory food habits' (34.7%), 'unwillingness to suffer nutritional deprivation' (33.3%), 'difficulties to conciliate a diet with family life' (27.8%) and 'taking cholesterol-lowering drugs' (22.2%). Despite a generally good understanding by patients of doctors' recommendations, some discrepancies were seen between their respective declarations. While doctors largely thought that patients needed more explanation on why and how a diet can lower cholesterol (and avoid taking drugs), only 39.4% of patients declared needing this kind of information. Other discrepancies were observed concerning barriers to, and motivators for, patient adherence. Moreover, some dietetic rules appeared to be more difficult to comply with than others, e.g. 82.6% patients remembered they should 'eat more fish' but only 51.3% actually did so. Finally, physicians, as well as patients, displayed a lack of confidence in lipid-lowering diet efficiency.

Cohort studies of at least one year’s follow-up period were included. Review methods Identified articles were systematically reviewed and those with pertinent data were selected for meta-analysis. Pooled risk ratios (RRs) with 95% confidence intervals (CIs) for all-cause mortality, CVD mortality and CVD incidence were calculated using the random-effects model with inverse-variance weighting. Results We included 17 studies for a systematic review, followed by a meta-analysis using pertinent data. Of the 272,216 people in 4 cohort studies using the low-carbohydrate score, 15,981 (5.9%) cases of death from all-cause were reported. The risk of all-cause mortality among those with high low-carbohydrate score was significantly elevated: the pooled RR (95% CI) was 1.31 (1.07–1.59).

RESULTS: The fat energy exceeded that of protein. There has been a loss of n-3 fatty acids. The n-6:n-3 ratio was found to be as high as 9:1, as opposed to the recommendation of about 2:1.

While a variety of genotoxic effects of phytoestrogens have been reported in vitro, the concentrations at which such effects occurred were often much higher than the physiologically relevant doses achievable by dietary or pharmacologic intake of soy foods or supplements. This review focuses on in vitro studies of the most abundant soy phytoestrogen, genistein, critically examining dose as a crucial determinant of cellular effects.

AIM OF THE STUDY: Insulin resistance values were assessed in relation to different nutrition. Metabolic abnormality is a predictor of age-related diseases and can be more pronounced in obese subjects. Insulin resistance values in normal weight subjects of two different nutritional habits were correlated with age. METHODS: Fasting concentrations of glucose and insulin as well as calculated values of insulin resistance IR (HOMA) were assessed in two nutritional groups of apparently healthy adult subjects (age range 19 - 64 years) with normal weight (body mass index 18.6 - 25.0 kg/m(2)): a vegetarian group (95 long-term lacto-ovo-vegetarians; duration of vegetarianism 10.2 +/- 0.5 years) and a non-vegetarian control group (107 subjects of general population on traditional western diet). Intake of energy and main nutrients (fats, saccharides, proteins) was similar in both groups. RESULTS: Glucose and insulin concentrations and IR (HOMA) values were significantly lower in vegetarians (glucose 4.47 +/- 0.05 vs. 4.71 +/- 0.07 mmol/l; insulin 4.96 +/- 0.23 vs. 7.32 +/- 0.41 mU/l; IR (HOMA) 0.99 +/- 0.05 vs. 1.59 +/- 0.10).

Sildenafil-treated men had a higher risk for all-cause AEs (RR = 1.56, 95% CI: 1.38, 1.76), headache, flushing, dyspepsia, and visual disturbances compared with placebo-treated men. The magnitude of excess risk was greater in fixed- than in flexible-dose trials. The rates of serious adverse events and withdrawals because of adverse events did not differ in sildenafil vs placebo groups. A higher dose of sildenafil corresponded to a greater risk of AEs. The increased risk of harms was observed within and across clinically defined specific groups of patients. CONCLUSIONS: There was a lack of RCTs reporting long-term (>6 months) harms data. In short-term trials, men with ED randomized to sildenafil had an increased risk of all-cause any AEs, headache, flushing, dyspepsia, and visual disturbances.

METHODS: A sample of 15 subjects was analyzed, all from northern Italy and aged 24 to 60 year, composed of 11 men and 4 women who had been following a vegan diet for a minimum of 18 months to a maximum of 20 years. In parallel with the study sample, a control group (15 subjects) with the same criteria of age, sex, and place of origin all following an omnivorous diet was chosen. The sample answered a questionnaire that investigated their eating habits, the frequency with which they eat meals, the main foodstuffs assumed, oral hygiene habits, and any painful symptomatology of the teeth or more general problems in the oral cavity. The sample was then subject to objective examination in which the saliva pH was measured and the teeth were checked for demineralization of the enamel, white spots, and caries (using KaVo DIAGNOdent) with particular attention being paid to the localization of these lesions, and lastly, sounding was carried out to detect any osseous defects and periodontal pockets. RESULTS: The study revealed greater incidence of demineralization and white spots in the vegan subjects compared to the omnivorous ones localized at the neck of the teeth and on the vestibular surfaces of dental elements (with the exception of the lower anterior group). The saliva pH, more acid in the omnivorous patients, ranged between four and six. Changes in oral conditions in both groups of subjects were observed.

Subsequently, many dietary intervention trials investigated the effects of nut consumption on blood lipid levels. The objectives of this study were to estimate the effects of nut consumption on blood lipid levels and to examine whether different factors modify the effects. METHODS: We pooled individual primary data from 25 nut consumption trials conducted in 7 countries among 583 men and women with normolipidemia and hypercholesterolemia who were not taking lipid-lowering medications. In a pooled analysis, we used mixed linear models to assess the effects of nut consumption and the potential interactions. RESULTS: With a mean daily consumption of 67 g of nuts, the following estimated mean reductions were achieved: total cholesterol concentration (10.9 mg/dL [5.1% change]), low-density lipoprotein cholesterol concentration (LDL-C) (10.2 mg/dL [7.4% change]), ratio of LDL-C to high-density lipoprotein cholesterol concentration (HDL-C) (0.22 [8.3% change]), and ratio of total cholesterol concentration to HDL-C (0.24 [5.6% change]) (P < .001 for all) (to convert all cholesterol concentrations to millimoles per liter, multiply by 0.0259). Triglyceride levels were reduced by 20.6 mg/dL (10.2%) in subjects with blood triglyceride levels of at least 150 mg/dL (P < .05) but not in those with lower levels (to convert triglyceride level to millimoles per liter, multiply by 0.0113). The effects of nut consumption were dose related, and different types of nuts had similar effects on blood lipid levels. The effects of nut consumption were significantly modified by LDL-C, body mass index, and diet type: the lipid-lowering effects of nut consumption were greatest among subjects with high baseline LDL-C and with low body mass index and among those consuming Western diets.

DESIGN: Middle-aged unmedicated subjects (n = 72) with cardiovascular risk factors consumed moderate amounts of berry or control products for 8 wk in a single-blind, randomized, placebo-controlled intervention trial. RESULTS: Berry consumption inhibited platelet function as measured with a platelet function analyzer (using collagen and ADP as platelet activator) [changes: 11% and -1.4% in the berry and control groups, respectively; P = 0.018, analysis of covariance (ANCOVA)]. Plasma biomarkers of platelet activation, coagulation, and fibrinolysis did not change during the intervention.

DESIGN: Cross-sectional analysis of National Health and Nutrition Examination Survey (1999-2004) dietary and anthropometric data. Diet quality was determined using United States Department of Agriculture's Healthy Eating Index 2005. Participants included adults aged 19 years and older, excluding pregnant and lactating women (N = 13,292). Lacto-ovo vegetarian diets were portrayed by intakes of participants who did not eat meat, poultry, or fish on the day of the survey (n = 851). Weight-loss diets were portrayed by intakes of participants who consumed 500 kcal less than their estimated energy requirements (n = 4,635). Mean nutrient intakes and body mass indexes were adjusted for energy, sex, and ethnicity. Using analysis of variance, all vegetarians were compared to all nonvegetarians, dieting vegetarians to dieting nonvegetarians, and nondieting vegetarians to nondieting nonvegetarians. RESULTS: Mean intakes of fiber, vitamins A, C, and E, thiamin, riboflavin, folate, calcium, magnesium, and iron were higher for all vegetarians than for all nonvegetarians. Although vegetarian intakes of vitamin E, vitamin A, and magnesium exceeded that of nonvegetarians (8.3 ± 0.3 vs 7.0 ± 0.1 mg; 718 ± 28 vs 603 ± 10 μg; 322 ± 5 vs 281 ± 2 mg), both groups had intakes that were less than desired.

The purpose of the present study was to determine the efficacy of the Daniel Fast to improve markers of metabolic and cardiovascular disease risk. Methods 43 subjects (13 men; 30 women; 35 ± 1 yrs; range: 20-62 yrs) completed a 21 day period of modified food intake in accordance with detailed guidelines provided by investigators. All subjects purchased and prepared their own food. Following initial screening, subjects were given one week to prepare for the fast, after which time they reported to the lab for their pre-intervention assessment (day 1). After the 21 day fast, subjects reported to the lab for their post-intervention assessment (day 22). For both visits, subjects reported in a 12 hr fasted state, performing no strenuous physical activity during the preceding 24-48 hrs. At each visit, mental and physical health (SF-12 form), resting heart rate and blood pressure, and anthropometric variables were measured. Blood was collected for determination of complete blood count, metabolic panel, lipid panel, insulin, HOMA-IR, and C-reactive protein (CRP). Subjects' self-reported compliance, mood, and satiety in relation to the fast were also recorded. Diet records were maintained by all subjects during the 7 day period immediately prior to the fast (usual intake) and during the final 7 days of the fast. Results Subjects' compliance to the fast was 98.7 ± 0.2% (mean ± SEM). Using a 10 point scale, subjects' mood and satiety were both 7.9 ± 0.2. The following variables were significantly (p < 0.05) lower following the fast as compared to before the fast: white blood cell count (5.68 ± 0.24 vs. 4.99 ± 0.19 103·μL-1), blood urea nitrogen (13.07 ± 0.58 vs. 10.14 ± 0.59 mg·dL-1), blood urea nitrogen/creatinine (14.74 ± 0.59 vs. 11.67 ± 0.68), protein (6.95 ± 0.07 vs. 6.77 ± 0.06 g·dL-1), total cholesterol (171.07 ± 4.57 vs. 138.69 ± 4.39 mg·dL-1), LDL-C (98.38 ± 3.89 vs. 76.07 ± 3.53 mg·dL-1), HDL-C (55.65 ± 2.50 vs. 47.58 ± 2.19 mg·dL-1), SBP (114.65 ± 2.34 vs. 105.93 ± 2.12 mmHg), and DBP (72.23 ± 1.59 vs. 67.00 ± 1.43 mmHg). Insulin (4.42 ± 0.52 vs. 3.37 ± 0.35 μU·mL-1; p = 0.10), HOMA-IR (0.97 ± 0.13 vs.0.72 ± 0.08; p = 0.10), and CRP (3.15 ± 0.91 vs. 1.60 ± 0.42 mg·L-1; p = 0.13), were lowered to a clinically meaningful, albeit statistically insignificant extent.

Treatment was based on homocysteine, Lp (a), C-reactive protein (C-RP), triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, and fibrinogen levels. Each variable was independently treated as previously reported. MPI and ECHO were performed at the beginning and end of the study for each individual. The 16 people (treatment group/TG) studied modified their dietary intake as instructed. Ten additional individuals elected a different dietary regimen consisting of a \"high-protein\" (high protein group/HPG) diet, which they believed would \"improve\" their overall health. Patients in the TG demonstrated a reduction in each of the independent variables studied with regression in both the extent and severity of coronary artery disease (CAD) as quantitatively measured by MPI. Recovery of viable myocardium was seen in 43.75% of myocardial segments in these patients, documented with both MPI and ECHO evaluations. Individuals in the HPG showed worsening of their independent variables. Most notably, fibrinogen, Lp (a), and C-RP increased by an average of 14%, 106%, and 61% respectively. Progression of the extent and severity of CAD was documented in each of the vascular territories with an overall cumulative progression of 39.7%. The differences between progression and extension of disease in the HPG and the regression of disease in the TG were statistically (p<0.001) significant. Patients following recommended treatment for each of the independent variables were able to regress both the extent and severity of their coronary artery disease (CAD), as well as improve their myocardial wall motion (function) while following the prescribed medical and dietary guidelines. However, individuals receiving the same medical treatment but following a high-protein diet showed a worsening of independent risk factors, in addition to progression of CAD.

The blood platelets are of significant importance in medicine. These cells are involved in many physiological processes, particularly haemostasis through their ability to aggregate and form clots in response to activation. In addition, these dynamic cells display activities that extend beyond thrombosis, including an important role in initiating and sustaining vascular inflammation. The expansion of knowledge from basic and clinical research has highlighted the critical position of platelets in several inflammatory diseases such as arthritis and atherosclerosis. Platelets are emerging as important mediators of inflammation and provide important signals to mediate phenotype of other blood and vascular cells. The important role of platelets in arterial thrombosis and the onset of acute myocardial infarction after atherosclerotic plaque rupture make inhibition of platelet aggregation a critical step in preventing thrombotic events associated with stroke, heart attack, and peripheral arterial thrombosis. However, the use of platelet inhibitors for thrombosis prevention must seek a delicate balance between inhibiting platelet activation and an associated increased bleeding risk. The aim of this review is to up-date the knowledge on platelets physiology and dysfunction in pathologies, such as diabetes mellitus, hypercholesterolemia, and hypertension, emphasizing the link between platelets and the inflammation-related atherosclerosis.

Prevalence estimates were computed from cases identified at the 1991 to 1993 examination. Cognitive performance was assessed using standardized methods, instruments, and diagnostic criteria. PARTICIPANTS: Subjects were 3734 Japanese-American men (80% of surviving cohort) aged 71 through 93 years, living in the community or in institutions. MAIN OUTCOME MEASURES: Age-specific, age-standardized, and cohort prevalence estimates were computed for dementia (all cause) defined by 2 sets of diagnostic criteria and 4 levels of severity. Prevalence levels for Alzheimer disease and vascular dementia were also estimated. RESULTS: Dementia prevalence by Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised ranged from 2.1% in men aged 71 through 74 years to 33.4% in men aged 85 through 93 years. Age-standardized prevalence was 7.6%.

METHODS: The study included women (31,035 CVD-free and 5680 with CVD history at baseline), aged 49 to 83 years, from the Swedish Mammography Cohort. Diet was assessed with a food frequency questionnaire. Dietary TAC was calculated using oxygen radical absorbance capacity values.

Most guidelines recommend eating a diet with a high intake of fiber-rich food including fruit. This is based on the many positive effects of fruit on human health. However some health professionals have concerns that fruit intake has a negative impact on glycemic control and therefore recommend restricting the fruit intake. We found no studies addressing this important clinical question. The objective was to investigate whether an advice to reduce the intake of fruit to patients with type 2 diabetes affects HbA1c, bodyweight, waist circumference and fruit intake. Methods This was an open randomized controlled trial with two parallel groups. The primary outcome was a change in HbA1c during 12 weeks of intervention. Participants were randomized to one of two interventions; medical nutrition therapy + advice to consume at least two pieces of fruit a day (high-fruit) or medical nutrition therapy + advice to consume no more than two pieces of fruit a day (low-fruit). All participants had two consultations with a registered dietitian. Fruit intake was self-reported using 3-day fruit records and dietary recalls. All assessments were made by the “intention to treat” principle. Results The study population consisted of 63 men and women with newly diagnosed type 2 diabetes. All patients completed the trial. The high-fruit group increased fruit intake with 125 grams (CI 95%; 78 to 172) and the low-fruit group reduced intake with 51 grams (CI 95%; -18 to −83). HbA1c decreased in both groups with no difference between the groups (diff.: 0.19%, CI 95%; -0.23 to 0.62). Both groups reduced body weight and waist circumference, however there was no difference between the groups. Conclusions A recommendation to reduce fruit intake as part of standard medical nutrition therapy in overweight patients with newly diagnosed type 2 diabetes resulted in eating less fruit.

Up to the turn of the century, the theory received abundant support from observations coming from fields as far apart as comparative physiology or molecular biology. Recent Advances: Work from many laboratories supports the theory, for instance showing that overexpression of antioxidant enzymes results in increases in life-span. But other labs have shown that in some cases, there is an increased oxidative stress and increased longevity. The discovery that free radicals can not only cause molecular damage to cells, but also serve as signals; led to the proposal that they act as modulators of physiological processes. For instance, reactive oxygen species (ROS) stimulate physiological adaptations to physical exercise. Critical Issues: A critical blow to the free radical theory of aging came from epidemiological studies showing that antioxidant supplementation did not lower the incidence of many age-associated diseases but, in some cases, increased the risk of death. Moreover, recent molecular evidence has shown that increasing generation of ROS, in some cases, increases longevity. Future Directions: Gerontologists interested in free radical biology are at a crossroads and clearly new insights are required to clarify the role of ROS in the process of aging.

Progressive shortening of telomeres leads to senescence, apoptosis, or oncogenic transformation of somatic cells, affecting the health and lifespan of an individual. Shorter telomeres have been associated with increased incidence of diseases and poor survival. The rate of telomere shortening can be either increased or decreased by specific lifestyle factors. Better choice of diet and activities has great potential to reduce the rate of telomere shortening or at least prevent excessive telomere attrition, leading to delayed onset of age-associated diseases and increased lifespan.

METHODS: The GWTG database was analyzed for ACS-related hospitalizations from 2005 to 2009. The use of LLT (defined as dose of statin or combination therapy likely to produce>50% reductions in low-density lipoprotein [LDL]) and less intensive LLT at discharge was assessed. Baseline characteristics and temporal trends in LLT were compared in these 2 treatment groups. RESULTS: Of 65,396 patients receiving LLT, only 25,036 (38.3%) were treated with an LLT regimen. Mean total cholesterol, LDL, and triglycerides were significantly higher in the LLT group. Even among those with LDL>130 mg/dL, 50% or less received LLT. Predictors of LLT at discharge included LLT before admission, hyperlipidemia, prior coronary artery disease, increasing body mass index, and in-hospital percutaneous coronary intervention. Although there was some temporal improvement in the rate of LLT from 2005 to 2007, a decline in use of LLT was noted in 2008 and 2009.

The Oxygen Radical Absorbance Capacity (ORAC) assay, which measures total antioxidant capacity of individual foods and accounts for synergism, can be estimated using a food-frequency questionnaire (FFQ). We tested the hypothesis that higher intake of antioxidant nutrients from foods, supplements, and FFQ-based ORAC values are associated with a lower risk of NHL in a clinic-based study of 603 incident cases and 1007 frequency-matched controls. Diet was assessed with a 128-item FFQ. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals adjusted for age, sex, residence and total energy. Dietary intake of α-tocopherol (OR=0.50; p-trend=0.0002), β-carotene (OR=0.58; p-trend=0.0005), lutein/zeaxanthin (OR=0.62; p-trend=0.005), zinc (OR=0.54; p-trend=0.003) and chromium (OR=0.68; p-trend=0.032) were inversely associated with NHL risk.

Design: A prospective study was conducted in 13,475 women who reported a singleton pregnancy between 1991 and 2001 in the Nurses’ Health Study II.

Better lifestyle choices; physical exercise; improved nutrition and weight control; adequate intake of or supplementation with omega-3 fatty acids, antioxidants, calcium, and folic acid; and replacement of any testosterone deficiency will all improve vascular and erectile function and the response to phosphodiesterase-5 inhibitors, which also increase vascular NO production. More frequent penile-specific exercise improves local endothelial NO production. Excessive intake of vitamin E, calcium, l-arginine, or l-citrulline may impart significant cardiovascular risks. Interventions discussed also lower blood pressure or prevent hypertension. Certain angiotensin II receptor blockers improve erectile function and reduce oxidative stress. In men aged <60 years and in men with diabetes or hypertension, erectile dysfunction can be a critical warning sign for existing or impending cardiovascular disease and risk for death.

METHODS: We studied 2401 white twin volunteers, comprising 2152 women and 249 men, with questionnaires on physical activity level, smoking status, and socioeconomic status. Leukocyte telomere length was derived from the mean terminal restriction fragment length and adjusted for age and other potential confounders.

Adiponectin is an adipocyte-derived hormone mainly produced by subcutaneous fat that shows important protective anti-inflammatory and vasodilatory effects. We hypothesized that adiponectin expressed in the subcutaneous adipose tissue (SAT) might play a role in the pathogenesis of cellulite.

The Atkins Diet is low in carbohydrate and usually high in fat; the Japanese diet is high in carbohydrate and usually low in fat. Yet both work to promote weight loss. One commonality of both diets is that they both eliminate the monosaccharide fructose. Sucrose (table sugar) and its synthetic sister high fructose corn syrup consist of 2 molecules, glucose and fructose. Glucose is the molecule that when polymerized forms starch, which has a high glycemic index, generates an insulin response, and is not particularly sweet. Fructose is found in fruit, does not generate an insulin response, and is very sweet. Fructose consumption has increased worldwide, paralleling the obesity and chronic metabolic disease pandemic. Sugar (i.e., fructose-containing mixtures) has been vilified by nutritionists for ages as a source of “empty calories,” no different from any other empty calorie. However, fructose is unlike glucose. In the hypercaloric glycogen-replete state, intermediary metabolites from fructose metabolism overwhelm hepatic mitochondrial capacity, which promotes de novo lipogenesis and leads to hepatic insulin resistance, which drives chronic metabolic disease. Fructose also promotes reactive oxygen species formation, which leads to cellular dysfunction and aging, and promotes changes in the brain’s reward system, which drives excessive consumption. Thus, fructose can exert detrimental health effects beyond its calories and in ways that mimic those of ethanol, its metabolic cousin. Indeed, the only distinction is that because fructose is not metabolized in the central nervous system, it does not exert the acute neuronal depression experienced by those imbibing ethanol. These metabolic and hedonic analogies argue that fructose should be thought of as “alcohol without the buzz.”", "title": "Fructose: It’s “Alcohol Without the Buzz”" }, { "docid": "MED-3816", "text": "Most of adult women exhibit cellulite on the hips, buttock and thighs. Although extracellular matrix and lymphatic system disorders can increase its appearance, cellulite basically results from an excessive fat storage in the adipose tissue which exerts considerable pressure on the surrounding skin tissue and creates a dimpled irregular appearance. Caffeine, the most widely used anti-cellulite ingredient, favours fat break-down by inhibiting the phosphodiesterase enzyme and encouraging a high intracellular level of cAMP. A series of studies has shown that spermine and spermidine, two ubiquitous polyamines, encouraged fat storage and slowed fat break-down in the adipose tissue. Besides, it was shown that heparan sulfate glycosaminoglycans had a strong affinity for polyamines. To design a new cosmetic ingredient with anti-cellulite properties, we used molecular modelling to screen several ingredients with a structure similar to that of heparan sulfate glycosaminoglycans. This way, we identified sulfo-carrabiose as a potent molecule for trapping spermine and spermidine. These virtual results were first confirmed in tubo where sulfo-carrabiose was shown to dose-dependently inactivate spermine and spermidine. In vitro, adipocytes cultured with sulfo-carrabiose exhibited a significant reduction of lipogenesis and a significant increase of lipolysis. When sulfo-carrabiose was incorporated in a cosmetic formula, significant improvements were observed in thigh circumference, with better results than those obtained with caffeine after 28 days of use.

No complete revision of global disease burden caused by risk factors has been done since a comparative risk assessment in 2000, and no previous analysis has assessed changes in burden attributable to risk factors over time. Methods We estimated deaths and disability-adjusted life years (DALYs; sum of years lived with disability [YLD] and years of life lost [YLL]) attributable to the independent effects of 67 risk factors and clusters of risk factors for 21 regions in 1990 and 2010. We estimated exposure distributions for each year, region, sex, and age group, and relative risks per unit of exposure by systematically reviewing and synthesising published and unpublished data. We used these estimates, together with estimates of cause-specific deaths and DALYs from the Global Burden of Disease Study 2010, to calculate the burden attributable to each risk factor exposure compared with the theoretical-minimum-risk exposure. We incorporated uncertainty in disease burden, relative risks, and exposures into our estimates of attributable burden. Findings In 2010, the three leading risk factors for global disease burden were high blood pressure (7·0% [95% uncertainty interval 6·2–7·7] of global DALYs), tobacco smoking including second-hand smoke (6·3% [5·5–7·0]), and alcohol use (5·5% [5·0–5·9]). In 1990, the leading risks were childhood underweight (7·9% [6·8–9·4]), household air pollution from solid fuels (HAP; 7·0% [5·6–8·3]), and tobacco smoking including second-hand smoke (6·1% [5·4–6·8]). Dietary risk factors and physical inactivity collectively accounted for 10·0% (95% UI 9·2–10·8) of global DALYs in 2010, with the most prominent dietary risks being diets low in fruits and those high in sodium. Several risks that primarily affect childhood communicable diseases, including unimproved water and sanitation and childhood micronutrient deficiencies, fell in rank between 1990 and 2010, with unimproved water we and sanitation accounting for 0·9% (0·4–1·6) of global DALYs in 2010. However, in most of sub-Saharan Africa childhood underweight, HAP, and non-exclusive and discontinued breastfeeding were the leading risks in 2010, while HAP was the leading risk in south Asia. The leading risk factor in Eastern Europe, most of Latin America, and southern sub-Saharan Africa in 2010 was alcohol use; in most of Asia, North Africa and Middle East, and central Europe it was high blood pressure. Despite declines, tobacco smoking including second-hand smoke remained the leading risk in high-income north America and western Europe. High body-mass index has increased globally and it is the leading risk in Australasia and southern Latin America, and also ranks high in other high-income regions, North Africa and Middle East, and Oceania. Interpretation Worldwide, the contribution of different risk factors to disease burden has changed substantially, with a shift away from risks for communicable diseases in children towards those for non-communicable diseases in adults. These changes are related to the ageing population, decreased mortality among children younger than 5 years, changes in cause-of-death composition, and changes in risk factor exposures. New evidence has led to changes in the magnitude of key risks including unimproved water and sanitation, vitamin A and zinc deficiencies, and ambient particulate matter pollution. The extent to which the epidemiological shift has occurred and what the leading risks currently are varies greatly across regions. In much of sub-Saharan Africa, the leading risks are still those associated with poverty and those that affect children.

Nevertheless, no prospective study from Asia has assessed blood or urine levels as biomarkers of isoflavone intake. PATIENTS AND METHODS: A total of 24,226 women ages 40 to 69 years in the Japan Public Health Center-based prospective study who responded to the baseline questionnaire and provided blood in 1990 to 1995 were observed to December 2002. During a mean 10.6 years of follow-up, 144 patients newly diagnosed with breast cancer were identified. Two matched controls for each patient were selected from the cohort. Isoflavone levels were assessed by plasma level and food frequency questionnaire, and the odds ratio of breast cancer according to isoflavone level was estimated using a conditional logistic regression model. RESULTS: We found a statistically significant inverse association between plasma genistein and risk of breast cancer, but no association for plasma daidzein. Adjusted odds ratios for the highest versus lowest quartile of plasma level were 0.34 for genistein (95% CI, 0.16 to 0.74; P for trend, .02) and 0.71 for daidzein (95% CI, 0.35 to 1.44; P for trend, .54).

Our aim was to establish whether antioxidant supplements reduce the incidence of gastrointestinal cancer and mortality. METHODS: With the Cochrane Collaboration methodology, we reviewed all randomised trials comparing antioxidant supplements with placebo for prevention of gastrointestinal cancers. We searched electronic databases and reference lists (February, 2003). Outcome measures were incidence of gastrointestinal cancers, overall mortality, and adverse effects. Outcomes were analysed with fixed-effect and random-effects model meta-analyses and were reported as relative risk with 95% CIs. FINDINGS: We identified 14 randomised trials (n=170,525). Trial quality was generally high. Heterogeneity of results was low to moderate. Neither the fixed-effect (relative risk 0.96, 95% CI 0.88-1.04) nor random-effects meta-analyses (0.90, 0.77-1.05) showed significant effects of supplementation with beta-carotene, vitamins A, C, E, and selenium (alone or in combination) versus placebo on oesophageal, gastric, colorectal, pancreatic, and liver cancer incidences. In seven high-quality trials (n=131727), the fixed-effect model showed that antioxidant significantly increased mortality (1.06, 1.02-1.10), unlike the random-effects meta-analysis (1.06, 0.98-1.15). Low-quality trials showed no significant effect of antioxidant supplementation on mortality. The difference between the mortality estimates in high-quality and low-quality trials was significant (Z=2.10, p=0.04 by test of interaction). beta-carotene and vitamin A (1.29, 1.14-1.45) and beta-carotene and vitamin E (1.10, 1.01-1.20) significantly increased mortality, whereas beta-carotene alone only tended to increase mortality (1.05, 0.99-1.11). In four trials (three with unclear or inadequate methodology), selenium showed significant beneficial effect on the incidence of gastrointestinal cancer.

Methods: This study investigated arterial function in vegetarianism by comparing 49 healthy postmenopausal vegetarians with 41 age-matched omnivores.

Fasting blood levels of glucose, lipids, lipoprotein (a), high-sensitivity C-reactive protein, homocysteine, and vitamin B12 were also measured. Results: Vegetarians had significantly lower serum cholesterol, high-density and low-density lipoprotein, and glucose compared with omnivores.

Methods This meta-analysis included individual participant data from 22 trials of statin versus control (n=134 537; mean LDL cholesterol difference 1·08 mmol/L; median follow-up 4·8 years) and five trials of more versus less statin (n=39 612; difference 0·51 mmol/L; 5·1 years). Major vascular events were major coronary events (ie, non-fatal myocardial infarction or coronary death), strokes, or coronary revascularisations. Participants were separated into five categories of baseline 5-year major vascular event risk on control therapy (no statin or low-intensity statin) (<5%, ≥5% to <10%, ≥10% to <20%, ≥20% to <30%, ≥30%); in each, the rate ratio (RR) per 1·0 mmol/L LDL cholesterol reduction was estimated. Findings Reduction of LDL cholesterol with a statin reduced the risk of major vascular events (RR 0·79, 95% CI 0·77–0·81, per 1·0 mmol/L reduction), largely irrespective of age, sex, baseline LDL cholesterol or previous vascular disease, and of vascular and all-cause mortality. The proportional reduction in major vascular events was at least as big in the two lowest risk categories as in the higher risk categories (RR per 1·0 mmol/L reduction from lowest to highest risk: 0·62 [99% CI 0·47–0·81], 0·69 [99% CI 0·60–0·79], 0·79 [99% CI 0·74–0·85], 0·81 [99% CI 0·77–0·86], and 0·79 [99% CI 0·74–0·84]; trend p=0·04), which reflected significant reductions in these two lowest risk categories in major coronary events (RR 0·57, 99% CI 0·36–0·89, p=0·0012, and 0·61, 99% CI 0·50–0·74, p<0·0001) and in coronary revascularisations (RR 0·52, 99% CI 0·35–0·75, and 0·63, 99% CI 0·51–0·79; both p<0·0001). For stroke, the reduction in risk in participants with 5-year risk of major vascular events lower than 10% (RR per 1·0 mmol/L LDL cholesterol reduction 0·76, 99% CI 0·61–0·95, p=0·0012) was also similar to that seen in higher risk categories (trend p=0·3). In participants without a history of vascular disease, statins reduced the risks of vascular (RR per 1·0 mmol/L LDL cholesterol reduction 0·85, 95% CI 0·77–0·95) and all-cause mortality (RR 0·91, 95% CI 0·85–0·97), and the proportional reductions were similar by baseline risk. There was no evidence that reduction of LDL cholesterol with a statin increased cancer incidence (RR per 1·0 mmol/L LDL cholesterol reduction 1·00, 95% CI 0·96–1·04), cancer mortality (RR 0·99, 95% CI 0·93–1·06), or other non-vascular mortality. Interpretation In individuals with 5-year risk of major vascular events lower than 10%, each 1 mmol/L reduction in LDL cholesterol produced an absolute reduction in major vascular events of about 11 per 1000 over 5 years.

Subjects/Methods Twenty out of 24 subjects completed a randomized, crossover feeding trial where all meals were provided by a metabolic kitchen. Each subject consumed two diets for 4 weeks each. The diets differed in phytosterol content (phytosterol-poor diet, 126 mg phytosterols/2000 kcal; phytosterol-abundant diet, 449 mg/2000 kcal) but were otherwise matched for nutrient content. Cholesterol absorption and excretion were determined by gas chromatograph/mass spectrometry after oral administration of stable isotopic tracers. Results The phytosterol-abundant diet resulted in lower cholesterol absorption [54.2 ± 2.2 % (95% confidence interval, 50.5%, 57.9%) vs. 73.2 ± 1.3% (69.5%, 76.9%), P<0.0001] and 79% higher fecal cholesterol excretion [1322 ± 112 (1083.2, 1483.3) vs. 739 ± 97 mg/day (530.1, 930.2), P<0.0001] relative to the phytosterol-poor diet.

INTERVENTION: Participants received dietary advice for 6 months on either a low-saturated fat therapeutic diet (control) or a dietary portfolio, for which counseling was delivered at different frequencies, that emphasized dietary incorporation of plant sterols, soy protein, viscous fibers, and nuts. Routine dietary portfolio involved 2 clinic visits over 6 months and intensive dietary portfolio involved 7 clinic visits over 6 months. MAIN OUTCOME MEASURES: Percentage change in serum LDL-C. RESULTS: In the modified intention-to-treat analysis of 345 participants, the overall attrition rate was not significantly different between treatments (18% for intensive dietary portfolio, 23% for routine dietary portfolio, and 26% for control; Fisher exact test, P = .33).

OBJECTIVES: To evaluate whether occlusion of lumbar and middle sacral arteries or serum cholesterol levels are associated with lower back pain and/or with disc degeneration. SUMMARY OF BACKGROUND DATA: Atherosclerosis in the wall of the abdominal aorta usually develops at the ostia of branching arteries and the bifurcation, and may obliterate orifices of lumbar and middle sacral arteries. Obstruction of these arteries causes ischemia in the lumbar spine and may result in back symptoms and disc degeneration. METHODS: MR aortography and cholesterol blood tests were performed on 51 patients with long-term lower back pain without specific findings (i.e., spinal or nerve root compression) in regular lumbar MR images. The patients ranged from 35 to 70 years of age (mean age, 56 years). Serum cholesterol and low-density lipoprotein (LDL) cholesterol levels were measured. To assess symptoms and disability NASS low back Outcome Instrument was used. RESULTS: Twenty-nine (78%) of 37 men and 11 (77%) of 14 women showed occluded lumbar and/or middle sacral arteries. The prevalence of occluded arteries was 2.5 times more than in subjects of corresponding age group in a Finnish necropsy material. Twenty-three (62%) men and seven (50%) women had significant disc degeneration. Disc degeneration was associated with occluded lumbar/middle sacral arteries (P = 0.035). Patients with occluded arteries or significant disc degeneration did not complain more severe symptoms than those without, whereas patients with above normal serum LDL cholesterol scored higher in neurogenic symptoms (P = 0.031) and complained more often severe pain (P = 0.049) than those with normal LDL cholesterol.

RESEARCH DESIGN AND METHODS: A comprehensive search of Medline, Embase, Lilacs, the Cochrane Clinical Trials Registry bibliographies of relevant papers, and expert input updated through September 1998 was undertaken. All randomized placebo-controlled trials were included in which fish oil supplementation was the only intervention in subjects with type 2 diabetes.

OBJECTIVES: This study was designed to test the ability of strawberry phenolic compounds to mitigate the postprandial effects of a high-fat meal on OxLDL as well as investigate the effects of phenolic compounds on lipid metabolism. METHODS: Twenty-four hyperlipidemic men and women (14 women, 10 men; mean age 50.9 +/- SD 15 years) were recruited to participate in this randomized, single-blind, placebo-controlled, 12-wk crossover trial.

Twice before randomization and once at the 6-week crossover point, subjects received either Str or Pbo with a high-fat challenge meal (HFM). TC, LDL, high-density lipoprotein cholesterol, TG, and OxLDL were measured at defined intervals for 6 h before and after HFM challenge. Fasting concentrations of blood variables at 0, 6, and 12 weeks were compared to assess chronic intake of Str or Pbo. RESULTS: After the HFM during the run-in period, TG and OxLDL were lower after Str than Pbo (p = 0.005, p = 0.01, and p = 0.0008, respectively).

HS decoctions and infusions of calyxes, and on occasion leaves, are used in at least 10 countries worldwide in the treatment of hypertension and hyperlipidemia with no reported adverse events or side effects. HS extracts have a low degree of toxicity with a LD50 ranging from 2,000 to over 5,000 mg/kg/day. There is no evidence of hepatic or renal toxicity as the result of HS extract consumption, except for possible adverse hepatic effects at high doses. There is evidence that HS acts as a diuretic, however in most cases the extract did not significantly influence electrolyte levels. Animal studies have consistently shown that consumption of HS extract reduces blood pressure in a dose dependent manner. In RCTs, the daily consumption of a tea or extract produced from HS calyxes significantly lowered systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adults with pre to moderate essential hypertension and type 2 diabetes. In addition, HS tea was as effective at lowering blood pressure as the commonly used blood pressure medication Captropril, but less effective than Lisinopril. Total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides were lowered in the majority of normolipidemic, hypolipidemic, and diabetic animal models, whereas high-density lipoprotein cholesterol (HDL-C) was generally not affected by the consumption of HS extract. Over half of the RCTs showed that daily consumption of HS tea or extracts had favorable influence on lipid profiles including reduced total cholesterol, LDL-C, triglycerides, as well as increased HDL-C.

A number of potential mechanisms have been proposed to explain the hypotensive and anticholesterol effects, but the most common explanation is the antioxidant effects of the anthocyanins inhibition of LDL-C oxidation, which impedes atherosclerosis, an important cardiovascular risk factor.

Data recorded from patients' charts at 6-month intervals for up to 2 years of follow-up (when available) included weight, blood pressure, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and cholesterol:HDL ratio. Non-parametric statistical testing using the Friedman rank order (exact) test for k-related samples was conducted. A follow-up survey on adherence and medication use was completed by 38 patients. RESULTS: Of the 33 patients who returned for follow-up after 1 year, the mean weight loss was 31 lbs (P = .000). Of the 19 patients who returned after 2 years, the mean weight loss was 53 lbs (P = .000), mean cholesterol fell by 13 points, LDL by 15 points, triglycerides by 17 points, and cardiac risk ratio dropped from 4.5 to 3.8. Changes in systolic and diastolic blood pressure were highly significant at all follow-up time intervals (P < or = .001). There was a significant correlation between adherence and degree of weight loss (P = .011). CONCLUSIONS: Weight loss was sustained in patients who returned for follow-up and was more substantial in those who reported good adherence to the recommendations. However, many patients were lost to follow-up. Favorable changes in lipid profile and blood pressure were noted. An HND diet has the potential to provide sustainable, significant, long-term weight loss and may provide substantial lowering of cardiac risk in patients who are motivated and provided with extended one-on-one counseling and follow-up visits. Development of tools to aid in patient retention is an area for possible further study. Clinical trials with long-term follow-up are needed to further test the therapeutic potential and to examine adherence and follow-up issues related to this dietary approach. An HND diet as demonstrated with this group may be the most health-favorable and effective way to lose weight for appropriately motivated patients.", "title": "Effect of a high nutrient density diet on long-term weight loss: a retrospective chart review." }, { "docid": "MED-1450", "text": "Background/objectives: To determine the effects of a low-fat plant-based diet program on anthropometric and biochemical measures in a multicenter corporate setting.

The study described here examined whether serum lipid levels or pharmacologically treated hyperlipidemia were associated with sciatica. METHODS: A nationally representative sample (n=8028) of Finns aged 30 years or over was interviewed and examined. Sciatica was assessed by a physician according to preset criteria. Information for the present purpose was available for 74.8% of the sample. RESULTS: The prevalence of sciatica was 3.3% for men and 2.2% for women.

The açaí palm (Euterpe oleracea Mart.), which is native to South America, produces a small, black-purple fruit which is edible. The fruit has recently become popular as a functional food due to its antioxidant potential. Although several studies have been conducted in vitro and with animals, little is known about the potential health benefits in humans aside from an increase in plasma anti-oxidant capacity. Metabolic syndrome is a condition which is defined by a cluster of risk factors for cardiovascular disease and/or type-2 diabetes. Preliminary studies indicate that a reduction in reactive oxygen species can assist in the normalization of the metabolic pathways involved in this syndrome. Methods This was an open label pilot study conducted with 10 overweight adults (BMI ≥ 25 kg/m2 and ≤ 30 kg/m2) who took 100 g açai pulp twice daily for 1 month. The study endpoints included levels of fasting plasma glucose, insulin, cholesterol, triglycerides, exhaled (breath) nitric oxide metabolites (eNO) and plasma levels of high sensitivity C-reactive protein (hs-CRP). The response of blood glucose, blood pressure and eNO to a standardized meal was determined at baseline and following the 30 day treatment. Results Compared to baseline, there were reductions in fasting glucose and insulin levels following the 30 day treatment (both p < 0.02). There was also a reduction in total cholesterol (p = 0.03), as well as borderline significant reductions in LDL-cholesterol and the ratio of total cholesterol to HDL-cholesterol (both p = 0.051). Compared to baseline, treatment with açai ameliorated the post-prandial increase in plasma glucose following the standardized meal, measured as the area under the curve (p = 0.047). There was no effect on blood pressure, hs-CRP or eNO. Conclusion In this uncontrolled pilot study, consumption of açai fruit pulp reduced levels of selected markers of metabolic disease risk in overweight adults, indicating that further studies are warranted.", "title": "Effects of Açai (Euterpe oleracea Mart.) berry preparation on metabolic parameters in a healthy overweight population: A pilot study" } ]

If you're just keeping track for personal reasons, I'd suggest that you set up your check (or journal entry, your preference) how you'd like it to be recorded. Then, memorize that transaction. This allows you to use it as many times as you need to, without having to set it up each time. (Also note: there is no way to record a transaction that decreases cash and increases equity.) If you're trying to keep track of everything according to accounting standards, which it should be if you've set up an official business, then you have a lot more tracking to do with each payment. Mortgage payments technically do not affect the equity accounts of the owners. Each mortgage payment should decrease the bank balance, increase interest expense and decrease the mortgage balance, not to mention tracking any escrow account you may have. The equity accounts would be affected if the owners are contributing funds to the bank account, but equity would increase at the time the funds are deposited, not when the mortgage payments are made.

Also, mortgage interest is tax deductible while margin interest isn't, pushing the net return even higher. $125k Generally, I recommend this figure to you because the biggest S&P collapse since the recession took off about 50% from the top. If you borrow $125k on margin, and the total value of the funds drop 50%, you shouldn't suffer margin calls.

Second mortgage Yes, you will have two loans that you're paying interest on. You've traded having less invested in securities & a capital gains tax bill for more liabilities, interest payments, interest deductions, more invested in securities, a higher combined rate of return. If you have $500k set aside in securities and want $500k in real estate, this is more than safe for you as you will most likely have a combined rate of return of ~5% on $500k with interest on $500k at ~3.5%. If you're in small cap value, you'll probably be grossing ~15% on $500k. You definitely need to secure your labor income with supplementary insurance. Start a new question if you need a model for that. Secure real estate with securities A local bank would be more likely to do this than a major one, but if you secure the house with the investment account with special provisions like giving them copies of your monthly statements, etc, you might even get a lower rate on your mortgage considering how over-secured the loan would be.

Hopefully the two records are consistent. In legal systems that descended from British common law (including the US), the two most common forms of ownership are tenancy in common meaning that, unless otherwise specified in the title deed, each of the owners has an equal share in the entire property, and can sell or bequeath his/her share without requiring the approval of the others, and joint tenancy with right of survivorship meaning that all owners have equal share, and if one owner dies, the survivors form a new JTWROS. Spouses generally own property, especially the home, in a special kind of JTWROS called tenancy by the entirety. On the other hand, the rule is that unless explicitly specified otherwise, tenancy in common with equal shares is how the owners hold the property. Other countries may have different default assumptions, and/or have multiple other forms of ownership (see e.g. here for the intricate rules applicable in India). Mortgages are a different issue. Most mortgages state that the mortgagees are jointly and severally liable for the mortgage payments meaning that the mortgage holder does not care who makes the payment but only that the mortgage payment is made in full. If one owner refuses to pay his share, the others cannot send in their shares of the mortgage payment due and tell the bank to sue the recalcitrant co-owner for his share of the payment: everybody is liable (and can be sued) for the unpaid amount, and if the bank forecloses, everybody's share in the property is seized, not just the share owned by the recalcitrant person. It is, of course, possible to for different co-owners to have separate mortgages for their individual shares, but the legalities (including questions such as whose lien is primary and whose secondary) are complicated. With regard to who paid what over the years of ownership, it does not matter as far as the ownership is concerned. If it is a tenancy in common with equal shares, the fact that the various owners paid the bills (mortgage payments, property taxes, repairs and maintenance) in unequal amounts does not change the ownership of the property unless a new deed is recorded with the new percentages. Now, the co-owners may decide among themselves as a matter of fairness that any money realized from a sale of the property should be divided up in accordance with the proportion that each contributed during the ownership, but that is a different issue. If I were a buyer of property titled as tenancy in common, I (or the bank who is lending me money to make the purchase) would issue separate checks to each co-seller in proportion to the percentages listed on the deed of ownership, and let them worry about whether they should transfer money among themselves to make it equitable.

Gift taxes might well be due if large sums of money change hands).", "title": "" }, { "docid": "143329", "text": "QuickBooks enterprise provide audit trail for recover the details of the deleted transaction so that you can re-create the transaction.

When the company decides to pay dividends, does it literally track down every single owner of that stock and deposit x cents per share in that person's bank account? (This sounds absolutely absurd and seems like it would be a logistical nightmare). In Stocks, the dividends are issued periodically. The dividend date is declared well in advance. As on end of the day on Dividend date, the list of individuals [or entities] who own the stock is available with the Stock-Exchange / Registrar of the companies. To this list the dividends are credited in next few days / weeks via banking channel. Most of this is automated. What if the owner is some high-frequency algorithm that buys and sells bonds and stocks in fractions of a second? On bonds, things work slightly differently. An Bond is initially issued for say 95 [discount of 5%] and payment of 100 after say 5 years. So when the person sells it after an year, he would logically look to get a price of 96. Of course there are other factors that could fetch him a price of 94.50 or 95.50. So every change in ownership factors in the logical rate of interest. The person who submits in on maturity gets 100. For the homeowner, I'm assuming he / she still makes mortgage payments to the initial bank they got the mortgage from, even if the bank no longer \"\"owns\"\" the mortgage. In this case, does the trader on the secondary market who owns the mortgage also come back to that bank to collect his interest payment? This depends on how the original financial institution sells the mortgage to new institutions. Generally the homeowner would keep paying initial financial institution and they would then take a margin and pay the secondary investor. If this was collateral-ized as Mortgage backed security, it is a very different story.\"", "title": "" } ]

A tax-on-tax is computed for the tax paid, which also would be owed by the employer if they were paying the full tax rate for the employee. As a clarification, this is not the employer being truly responsible for the employee's income; this is the employer compensating the employee further to offset their taxable income. This is effectively a fringe benefit, although it may be particularly useful in countries where either tax evasion is common (and thus an employer must compete with employers willing to pay under the table) or where employers are competing with others in nearby countries with lower tax rates. It is not the same thing as the employer making your income nontaxable, though, and has implications for your tax filing. Significantly, it is likely that if you have additional income beyond income from that employer, it is likely to be taxed at your highest tax rate, as the employer will likely calculate the tax due based on their income being the only income you have in that year. *Edit based on emphasis in question: I'm not from Singapore nor am I a lawyer, but based on my reading of the IRAS website, it looks like you do not have to file if you have no other source of income, because they have a No-Filing Service which takes income information from your employer automatically and generates a tax bill, which presumably would be fully paid in your case. This only aplies if you have no other sources of income, however; you still have to file if you have other sources of income since your employer would not know about them.

You keep a receipt for every expense - if you don't have a receipt, you can't count it as an expense, so keeping all the receipts is very, very important. An exception are investments, for example buying a computer that should last multiple years; there you can count a percentage of the investment as expense every year. All income, minus all expenses, is your profit. You pay tax and National Insurance contributions according to your profit. You can do whatever you like with the profit. Notice that I didn't mention any salary. Self employed means you have no salary, you have profits and do with them whatever you like. On the other hand, you pay taxes on these profits almost exactly as if they were income.

Umbrella companies can be anywhere from totally legal to extremely dodgy. If they promise you that you pay only five percent tax on your income through ingenious tricks, that's only until the tax office finds out and they will make you pay. Between self-employed and your own company, the big difference is whether you are actually working independently or not. If you work like an employee (take someone else's orders) and claim you are a company, the tax office doesn't like that. And if you pay very little taxes, they don't like that either. So self-employed is the safer choice but you will pay more taxes, close to what a normal employee would pay. Obviously you will have to pay tax on your income and NHS insurance. Obviously you are required to tell the government (actually HMRC) about your income. Not doing so would be tax evasion and get you into deep trouble when you are caught. I don't think you have to tell them the source of your income, but not telling them might look very suspicious and might get your accounts checked carefully. And unless you design a website for the mafia, why wouldn't you tell them? The bill payer will try to deduct your bill from their profits anyway, so it's no secret.

If I didn’t know better, I would think this guy was teaching me something. It’s a shame he did not do research before he started writing. Let’s say you buy a classic car. You take super good care of it, all original, mint condition. You paid cash for it out of your savings. This is a balance sheet transaction that has nothing to do with income. You traded your cash asset for a classic car asset. Now let’s say this car is so rare and you keep it in such good condition that it gains value every year. Maybe it was worth $15k when you bought it, but this year it’s already worth $17k. Great job on making a great purchase! But is that $2k gain counted as income to you? No, it is not. The value of that asset on your balance sheet went up, but you did not make anything off of that increase in value because you have not sold it. If you had to pay taxes on the increase in value every year, those taxes would essentially force you to sell that car to pay the taxes just because you took care of it. Additionally, in the long term, no one would want to own anything, so this would destroy the value of everyone’s stuff, but I digress. In this example, amazon stock is the car. The author is seeing the increase in stock value adding to the balance sheets of the investors who bought the stock and confusing that with income. Back to our example, let’s say your car increased in value $2k a year for two years and you decide to sell it for $19k - now we are about to realize some income! Since you bought it for $15k and sold for $19k, you earned an income of the difference, or $4k. Your income wasn’t $19k, because you originally put $15k in cash into the car. That cash was already saved from income you made in the past, and it is not counted again as income in this sale. Because you did not work for this new car sale income, but it was derived from asset growth, the income is called capital gains. You invested your capital ($15k) into the asset (car), and that asset appreciated. When you sold it, you received capital (money) back in exchange for that asset. The capital you received is more than what you invested, which is to say you gained $4k of capital by investing in and then selling your asset (car). Because you held the car for two years, you qualify for lower long term capital gains tax rate on that $4k. Had you sold it after year 1, you would’ve paid your regular normal income tax rate on those capital gains. Either way, you owe the tax when you sell the asset, not when it appreciates. I’m sure you realize this already, but if we change the car to amazon stock in my story, this is exactly how it works with investors. The author gets several things wrong 1 - amazon profits are not passed through to shareholders for income tax purposes. If amazon paid dividends, those dividends would be taxed at payout at the long term capital gains rate, and they would be paid out of cash amazon has left after it already paid corporate taxes on profits. Amazon has decided they can add more value to investors by using cash to grow instead of paying dividends. When the investors sell the stock, they will owe capital gains on the growth of that stock. If amazon is correct that using cash to grow, then investors will effectively pay more when they sell the stock than they would pay today if dividends were paid. 2 - asset appreciation is not income. Those investors will realize the income when they sell the stock, and they will pay the tax then. 3 - he is missing the point entirely on why amazon runs a low profit or how business strategy translates into financials. Low prices are not a function of low profitability. Low profitability could be an adverse result of low pricing, but being low profit in order to be low price is a ridiculous and failing strategy. Amazon’s low pricing is a function of their unparalleled buying power, unparalleled consumer and product data, amazing logistics prowess, clever loyalty programs like amazon prime, and many other brilliant things they’ve done. Their low profitability is a function of their investment in things like amazon fresh, amazon Alexa, drone delivery, automated convenience stores, building out cloud computing infrastructure, and many other R&amp;D projects, $4 billion in original content spending for amazon prime video, and all kinds of expenditures years ahead of when they become profitable. By the time consumers want it, amazon already built it three years ago - this is the power of amazon. Sometimes multi billion dollar experiments fail, and all that money was for nothing. Sometimes they lose money for a few years and then become the infrastructure that runs a third of the internet. Amazon does not let fear of failure stop them, they invest in growth with their cash. This is how Bezos thinks - how do we build the future, not how can I avoid tax I do need to make a disclaimer here - there could be special tax treatment of classic cars that makes my example not work. Also classic cars may not appreciate in value. I don’t know anything about classic cars, I just picked a politically neutral thing to put in my story and made some assumptions to illustrate how capital gains work.

Long term capital gains justified by the idea that they encourage people to hold stock and make long term investments rather than buying and then quickly reselling for a short-term profit. The lower tax rates also reflect the fact that many of these assets are already taxed as they are appreciating in value. Real-estate is usually taxed through local property taxes. Equity in US corporations realized by rising stock prices and dividends that are returned to stock holders reflect earnings from a corporation that are already taxed at the 35% Corporate tax rate. Taxing Capital gains as ordinary income would be a second tax on those same profits. Another problem with Long-term capital gains tax is that a big portion of the gains for assets held for multiple decades are not real gains. Inflation increases the price of assets held for longer periods, but you are still taxed on the full gain even if it would be a loss when inflation is calculated. Capital gains are also taxed differently depending on your income level. If you are in the 10% or 15% brackets then Long-term capital gains are assessed at 0%.

You would still have to pay personal income tax on your 70% share of the rent (the 30% you may be able to get deductions for but the rules are quite complicated and you should never just estimate). The only way to get money out of a corporation without paying personal income tax is by having a qualified dividend. That's quite complicated - your accounting has to be clear that the money being issued as a qualified dividend came from an economic profit, not from a paper profit resulting from the fact that you worked hard without paying yourself market value.", "title": "" }, { "docid": "57263", "text": "\"US federal tax law distinguishes many types of income. For most people, most of their income is \"\"earned income\"\", money you were paid to do a job. Another category of income is \"\"capital gains\"\", money you made from the sale of an asset. For a variety of reasons, capital gains tax rates are lower than earned income tax rates. (For example, it is common that much of the gain is not real profit but inflation. If you buy an asset for $10,000 and sell it for $15,000, you pay capital gains tax on the $5,000 profit. But what if prices in general since you bought the asset have gone up 50%? Then your entire profit is really inflation, you didn't actually make any money -- but you still have to pay a tax on the paper gain.) So if you make your money by investing in assets -- buying and selling at a profit -- you will pay lower taxes than if you made the same amount of money by receiving a salary from a job, or by running a business where you sell your time and expertise rather than an asset. But money made from assets -- capital gains -- is not tax free. It's just a lower tax. It MIGHT be that when combined with other deductions and tax credits this would result in you paying no taxes in a particular year. Maybe you could avoid paying taxes forever if you can take advantage of tax loopholes. But for most people, making money from capital gains could result in lower taxes per dollar of income than someone doing more ordinary work. Or it could result in higher taxes, if you factor in inflation, net present value of money, and so on. BTW Warren Buffet's \"\"secretary\"\" is not a typist.

Buying a house is not an expense, it is a transfer of assets. The house itself, is an asset. So if you have $100,000 in cash, buy a house for $35,000, your total assets will remain the same ($100,000), but your asset mix will be different (instead of $100,000 in cash, you now have $65,000 in cash, and $35,000 in property). You can expense the costs associated with buying the house (e.g. taxes, interest, legal fees), but the house itself stays on the asset side of your balance sheet. To refine the example above, if you buy the house for $35,000, and pay $5,000 in misc fees related to purchasing the house, your assets are now $95,000 ($60,000 in cash, $35,000 in house): the $5,000 reduction is from the actual fees associated with the purchase. It is these fees that lower your profit. Being not familiar with UK rules, in Canada and the US, and likely the UK, you would then depreciate the house over its useful life. The depreciation expense is deducted from your annual net income. If you rent out the house, what you can do is expense any maintenance fees, taxes, etc., on the house itself. This expense will count as a negative towards the rental income, lowering your effective taxable income from the rental. E.g. rent out a flat at $1,000/month, but your property taxes are $3,500/year, so your net income for tax purposes (i.e. your taxable income in this case) is $12,000-$3,500=$8,500.", "title": "" }, { "docid": "252843", "text": "FICA taxes are separate from federal and state income taxes. As a sole proprietor you owe all of those. Additionally, there is a difference with FICA when you are employed vs. self employed. Typically FICA taxes are actually split between the employer and the employee, so you pay half, they pay half. But when you're self employed, you pay both halves. This is what is commonly referred to as the self employment tax. If you are both employed and self employed as I am, your employer pays their portion of FICA on the income you earn there, and you pay both halves on the income you earn in your business. Edit: As @JoeTaxpayer added in his comment, you can specify an extra amount to be withheld from your pay when you fill out your W-4 form. This is separate from the calculation of how much to withhold based on dependents and such; see line 6 on the linked form. This could allow you to avoid making quarterly estimated payments for your self-employment income. I think this is much easier when your side income is predictable. Personally, I find it easier to come up with a percentage I must keep aside from my side income (for me this is about 35%), and then I immediately set that aside when I get paid. I make my quarterly estimated payments out of that money set aside. My side income can vary quite a bit though; if I could predict it better I would probably do the extra withholding. Yes, you need to pay taxes for FICA and federal income tax. I can't say exactly how much you should withhold though. If you have predictable deductions and such, it could be lower than you expect.

The term \"\"partnership\"\" refers to a specific business entity type in the U.S. I'm not sure if you're using it the same way. In a partnership in the U.S. you pay income tax on your share of the partnership's income whether or not you actually receive income in your personal account. There's not enough information here to know if that applies in your case.

Will it have to be translated by my Swiss accountants? - and if so - which parts of the documentation need to be translated!? As regards language, you will file a tax return on a U.S. form presumably in English. You will not have to submit your account information on any other form, so the fact that your documentation is in German does not matter. The only exception that comes to mind is that you could potentially get audited (just like anyone else filing taxes in the U.S.) in which case you might need to produce your documentation. That situation is rare enough that I wouldn't worry about it though. I'm not sure if they'd take it in German or force you to get a translation.

I also understand that any tax paid (on selling) in Switzerland will be deducted from the 15%!? Q) Is this correct!? The long-term capital gains rate is 15% for most people. (At very high incomes it is 20%.) It sounds like you would qualify for long-term (held for greater than 1 year) capital gains in this case, although the details might matter. There is a foreign tax credit, but I'm not completely sure if it would apply in this case. (If forced to guess, I would say that it does.) If you search for \"\"foreign tax credit\"\" and \"\"IRS\"\" you should get to the information that you need pretty quickly.

From the IRS website: Ordinary Dividends Ordinary (taxable) dividends are the most common type of distribution from a corporation or a mutual fund.

Has the company just not made a profit yet, or has it actually made a significant loss that your invoices would just be offsetting? If you're earning over £10,000 per year then invoicing through the company is preferable. Above that level, you'd be taking money from the company as dividends after paying 20% corporation tax with no other tax to pay on your personal tax return. As a sole trader you'd be paying 20% income tax and 9% NI. (Note however that the company can only pay dividends from profits, which is a problem if there are significant losses to offset.) Below £10,000, there's little difference. Through the company, you can take a salary of £7956 per year without paying any income tax or NI. With the new £2000 discount on employers' NI you could then take salary up to £10,000 and just pay 12% employee's NI. As a sole trader, you pay 9% Class 4 NI over £7956 and a fixed £143 per year for Class 2 NI. Paying 9% rather than 12% saves you £60, but then you add the £143. In practice the company would work out more expensive at this level because you'll probably want to pay an accountant to deal with the payroll for you. Having the company repay your £2000 from the invoices doesn't really save any tax if the company will become profitable in the future. You don't pay any tax now since the money you receive isn't income, and the company doesn't pay any tax if the extra £2000 of revenue doesn't put it back in profit. However, if the company is profitable next year then it will have an extra £2000 of profit that would otherwise have been offset against this year's loss, and you do end up paying 20% corporation tax on the £2000. You could still have the company repay the loan in order to delay the tax liability, but it's not really tax free money. Loaning additional money to the company has no tax benefit, you just give the company £1000 and get your original £1000 back later.

There are many differences but the pertinent and most important ones are as follows. The main difference in your case would be tax and administration. As a sole trader you would need to do a tax return once a year and if you earned less than £11.5k you wouldn't have to pay any UK tax, assuming you have no other income and are a \"\"standard\"\" tax payer. The current tax allowance is £11.5k although this can change. Submitting your own tax return is relatively straighforward although you may want to consult an accountant. It is generally easier to run as sole trader versus a Limited Company, ie less paperwork and beaureaucracy. If you go down the Limited Company route, the company would be liable to pay Corporation Tax on any profits and this process is more complicated and you would probably need an accountant to do that for you, which is likely to cost a few hundred pounds every year. You can do it yourself but the process is not as simple as doing your own income tax return. Also as a sole trader you can do what you like with any income, you can spend it and treat it as your own wages. You can't do that if you set up a Limited Company as the income is \"\"owned\"\" by the company and so you would need to in effect pay yourself a wage from the company. In other words it's more complex than if you are a sole trader. The main advantage to a Limited Company is that it is easier to sell the business if you want to at a later date. There is nothing stopping you setting up a Limited Company later on, after beign a sole trader if you want to.

Either you pay from your own pocket and then you get income tax relief on the payment, i.e. your gross salary is reduced by the gross pension contribution and income tax is recalculated with the excess either refunded to you or put in your pension (the details are a bit more complicated depending on your marginal tax rate, but the end result is the same). Or your company pays, and then you are never charged tax on the payment in the first place. From the company's point of view, the two are roughly the same. Either it pays you who then pays into your pension, or it pays straight into your pension. Either way the money going out from the company is treated as a cost that is offset against the company's revenue, reducing the amount of corporation tax the company has to pay. There are some National Insurance advantages to paying directly into the pension; neither you nor the company gets relief on NI if the payment goes via you, but no NI is paid in the first place if it goes direct from the company. [EDIT: your question is actually worded to suggest that you want to lend your company money from your own pocket, and then have that loan directly discharged by the company paying into your pension. That's no different to you just paying into your pension directly, and wouldn't have any better tax implications. For the rest of my answer, I assume that the idea is actually to lend your company money that it uses to make an immediate contribution to your pension (as part of your pay from that company), and then the company will repay the loan later by returning the money to you personally. Your pension and you are two separate entities legally.] However, in your case, what you're proposing is that the company should effectively make a loss paying into your pension: it's going to end up with more costs than revenue. So, there won't be any immediate tax saving because there wasn't revenue to pay corporation tax on in the first place. You also won't save tax because the loan will be made from previously taxed income or whatever. However, there will be a tax loss that can be carried forward and offset against future profits, so if you expect the company to make money in future to repay the loan, you might end up saving some corporation tax. You can also sometimes carry a tax loss back one year, so if your company had profits last year you could get some corporation tax back immediately. The repayment of the loan itself won't be subject to income tax as it's not income. So unless you can carry the loss back, you won't get any immediate tax relief by doing this, but it might give you a way to carry forward your annual allowance to future years, i.e. use it now and get the tax advantage later. However, the annual allowance can already be carried forward by up to three years, so this is only worthwhile if you expect that future revenue to repay the loan to arrive more than three years later. Also, this is only worthwhile if you'll continue to max out the annual allowance for paying into your pension in future years, otherwise you might as well just make the pension payment using that same revenue in future years. However, even if this beneficial tax-wise, I'm not sure if it's actually allowed; this might be viewed as an artificial transaction to avoid tax, and that could lead to HMRC disallowing the future tax relief. You might need to ask HMRC or an accountant about that. If you do make the loan, make sure it's clearly documented so you can show in future why the repayment shouldn't be treated as income.", "title": "" }, { "docid": "291614", "text": "how much taxes would I pay on my income from the rent they would pay me?

You're not on crack. Generally, if all the income is generated by your own personal services - this is the outcome. The benefit of S-Corp is when you have employees who generate your income, and you distribute to yourself profits that come out of other's personal services. In this case your distributions are exempt from FICA since it is not in fact a self-employment income. You'd still have to pay yourself a reasonable salary for your position (as a manager/officer), but it wouldn't have to cover all of the available profits. So if the IRS takes a position against you it would be that your salary should be to include the whole profits, since it is the compensation to you for the personal services that produced the income to the corporation (you). In many cases they might agree that a salary at the SS maximum limit would be reasonable - but that's only a speculation of mine. In that case you might gain some portion of the medicare tax (with the recent law changes at the levels you're talking about you'll pay some medicare anyway). There are a lot of accountants who take more aggressive position saying that not all of the distributions are liable for SE taxes, even if you're the sole employee of the corporation. These cases often end up in the Tax Court, and whatever the outcome, your legal fees become higher than the FICA savings. What is probably missing in your picture is the SS limit of (currently $112K) above which you don't pay social security tax, so whether you get it as a salary or as a distribution - that limit is the same. That is why you don't see a significant difference. I know there are a lot of accountants who'd disagree, but I would argue that for a sole employee of your company, S-Corp doesn't provide significant benefits over the disregarded LLC taxation, but has some additional overhead that adds to your expenses. Here's a link to a lawyer's blog where he suggests (and says many accountants follow) 60/40 division between salary and distributions. I.e.: his take, similarly to mine, is that most of the earnings have to be treated as salary. In your case, when the total is about 300K - you indeed will not get any FICA savings with such a division other than some of the medicare. Unusually low wages when compared to distributions can draw unwanted IRS scrutiny and an audit. An unfavorable audit will likely result in some portion of the distributions being reclassified as earned income for federal income tax purposes, which results in a deficiency assessment (i.e., a tax bill), interest on those unpaid taxes, and IRS penalties.

Is 'days to cover' a useful metric in identifying the potential for a short squeeze?
[ { "docid": "369437", "text": "SeekingAlpha has an article about short squeezes that states: The higher the number of days to cover means the possibility for a short squeeze is greater, and the potential size of the short squeeze is also greater Logically, this makes sense. A short squeeze occurs when a lack of supply meets excess demand for a stock, so the potential for a squeeze increases when supply and demand begin to get out of equilibrium. Think of two things that would cause the days to cover to increase and what effect they would have on supply and demand. The current short interest (numerator) increases. This implies that if some event triggers short sellers to cover their position, there are a higher number of short sellers who will need to do so. This heightens the chances that demand will exceed supply. The average daily volume (denominator) decreases. This implies that fewer investors are trading the stock, so if an event triggers short sellers to cover their positions, there might not be enough traders in the market willing to sell their shares. (Obviously, if a short-squeeze occurs, volume may increase because traders who were unwilling to sell their shares become willing).", "title": "" } ]
[ { "docid": "107045", "text": "Rich's answer captures the basic essence of short selling with example. I'd like to add these additional points: You typically need a specially-privileged brokerage account to perform short selling. If you didn't request short selling when you opened your account, odds are good you don't have it, and that's good because it's not something most people should ever consider doing. Short selling is an advanced trading strategy. Be sure you truly grok selling short before doing it. Consider that when buying stock (a.k.a. going long or taking a long position, in contrast to short) then your potential loss as a buyer is limited (i.e. stock goes to zero) and your potential gain unlimited (stock keeps going up, if you're lucky!) Whereas, with short selling, it's reversed: Your loss can be unlimited (stock keeps going up, if you're unlucky!) and your potential gain is limited (i.e. stock goes to zero.) The proceeds you receive from a short sale – and then some – need to stay in your account to offset the short position. Brokers require this. Typically, margin equivalent to 150% the market value of the shares sold short must be maintained in the account while the short position is open. The owner of the borrowed shares is still expecting his dividends, if any. You are responsible for covering the cost of those dividends out of your own pocket. To close or cover your short position, you initiate a buy to cover. This is simply a buy order with the intention that it will close out your matching short position. You may be forced to cover your short position before you want to and when it is to your disadvantage! Even if you have sufficient margin available to cover your short, there are cases when lenders need their shares back. If too many short sellers are forced to close out positions at the same time, they push up demand for the stock, increasing price and deepening their losses. When this happens, it's called a short squeeze. In the eyes of the public who mostly go long buying stock, short sellers are often reviled. However, some people and many short sellers believe they are providing balance to the market and preventing it sometimes from getting ahead of itself.

Pivot Points indicate price levels that are of significance in technical analysis of securities. Pivot Points are used to provide clarity for a trader as they are a predictive indicator of where a security might go. There are at least 6 different types of Pivot Points (Woodie Pivot Point, Fibonacci Pivot, Demark etc..) and they are different based on their formulas but generally serve the same concept. I will be answering your question using the Camarilla Pivot Point formula. Camarilla Pivot Point Formula Generally any Pivot Point formula uses a combination of the Open, High, Low and Close of the previous timeframe. Since you are technically a swing trader indicated by say between a couple of days to a couple of weeks, as I don't want to do day trading you should use a weekly 5 to 30 minute chart but you can also use a daily chart as well. So for example if you use a daily chart, you would use the Open, High, Low and Close of the previous day. Example of fictitious stock: MOSEX (Money Stack Exchange) 01/14/16: Open: 10.25, High: 12.55, Low: 9.65, Close: 11.50 On 01/15/16: R4 Level: 13.10, R3 Level: 12.30, R2 Level: 12.03, R1 Level: 11.77, Pivot Point: 11.23, S1 Level: 11.23, S2 Level: 10.97, S3 Level: 10.70, S4 Level: 9.91 R = Resistance, S = Support How to identify these Pivot Points? Most charting software already have built in overlays that will identify the pivot points for you but you can always find and draw them yourself with an annotation tool. Since we are using the Camarilla Pivot Point formula, the important Pivot Point levels are the R4 which is considered as the Breakout Pivot, the S4 which is considered as the Breakdown Pivot. R3 and S3 are Reversal Pivot Points. Once identify the Pivot Points how should you proceed in a trade? This is the million dollar question and without spoon feeding you requires you to come up with your own strategy. To distinguish yourself from being a novice and pro trader is to have a strategy in a trade. Now I don't really have the time to look for actual charts to provide examples with but generally this is what you should look for to proceed in a trade: Potential Buy/Short Signals: Potential Sell Signals: If a stock moves above the R3 Level but then crosses below it, this would be a sell signal. This is confirmed when their is a lower lower then the candle that first crosses below it. Sell a stock when S4 Level is confirmed. See above for the confirmation. Other Useful Tips: Use the Pivot Point as your support or resistance. The Pivot Point levels can be used for your stop loss. For example, with an S3 reversal buy signal, the S4 should be used as a stop loss. Conversely, the Pivot Point levels can also be used for your target prices. For example, with an S3 reversal buy signal, you should take some profits at R3 level. You should also use a combination of other indicators to give you more information to confirm if a signal is correct. Examples of a good combination is the RSI, MACD and Moving Averages.

Naked shorting isn't a violation of federal securities laws but it becomes an accounting problem when multiple people have claims to the same underlying assets. (I've seen companies that had 120% of their shares sold short, too funny, FWIW the market was correct as the company was worth nothing.) You can be naked short without knowing it. So there can be times when you will be forced to cover. Other people being forced to cover can result in a short squeeze. A risk. The other downside is that you have to pay interest on your borrowings. You also have to pay the dividends to the owner of the shares, if applicable.

That is not true. Stocks can sometimes go up significantly (50-100% or more) in a very short amount of time on a positive news release (such as an earnings or a buyout announcement). A famous example occurred in 2008, when Volkswagen stock quintupled (went up 400%) in less than 2 days on some corporate news: Porsche, for some reason, wants to control Volkswagen, and by building up its stake has driven up the price. Hedge funds, figuring the share price would fall as soon as Porsche got control and stopped buying, sold a lot of VW shares short. Then last weekend, Porsche disclosed that it owned 42.6 percent of the stock and had acquired options for another 31.5 percent. It said it wanted to go to 75 percent. The result: instant short-squeeze. The German state of Lower Saxony owns a 20 percent stake in VW, which it said it would not sell. That left precious few shares available for anyone else.

If you did get assigned on your short option, then (I think) the T+3 settlement rules would matter for you. Basically you have 3 days to deliver. You'll get a note from your broker demanding that you provide the stock and probably threatening to liquidate assets in your account to cover their costs if you don't comply. If you still have the long-leg of the calendar spread then you can obtain the stock by exercising your long call, or, if you have sufficient funds available, you can just buy the stock and keep your long call. (If you're planning to exercise the long call to cover the position, then you need to check with your broker to see how quickly the stock so-obtained will get credited to your account since it also has some settlement timeline. It's possible that you may not be able to get the stock quickly enough, especially if you act on day 3.) Note that this is why you must buy the call with the far date. It is your \"\"insurance\"\" against a big move against you and getting assigned on your short call at a price that you cannot cover.

Usually brokers put additional restrictions on trades within IRAs just for this reason. Finally, in the cash account and assuming that you are assigned on your short call, you could potentially could get hit with a good faith, cash liquidation, or free riding violation when your short call is assigned, depending on how you deliver the stock and other things that you're doing in the same account.

Pivot Points use the prior period's high, low and close to formulate future support and resistance. In this regard, Pivot Points are predictive or leading indicators. There are at least five different versions of Pivot Points. I will focus on Standard Pivot Points here as they are the simplest. If you are looking to trade off daily charts you would work out your Pivot Points from the prior month's data. For example, Pivot Points for first trading day of February would be based on the high, low and close for January. They remain the same for the entire month of February. New Pivot Points would then be calculated on the first trading day of March using the high, low and close for February. To work out the Standard Pivot Points you use the High, Low and Close from the previous period (i.e. for daily charts it would be from the previous month) in the following formulas: You will now have 5 horizontal lines: P, R1, R2, S1 and S2 which will set the general tone for price action over the next month. A move above the Pivot Point P suggests strength with a target to the first resistance R1. A break above first resistance shows even more strength with a target to the second resistance level R2. The converse is true on the downside. A move below the Pivot Point P suggests weakness with a target to the first support level S1. A break below the first support level shows even more weakness with a target to the second support level S2. The second resistance and support levels (R2 & S2) can also be used to identify potentially overbought and oversold situations. A move above the second resistance level R2 would show strength, but it would also indicate an overbought situation that could give way to a pullback. Similarly, a move below the second support level S2 would show weakness, but would also suggest a short-term oversold condition that could give way to a bounce. This could be used together with a momentum indicator such as RSI or Stochastic to confirm overbought or oversold conditions. Pivot Points offer a methodology to determine price direction and then set support and resistance levels, however, it is important to confirm Pivot Point signals with other technical analysis indicators, such as candle stick reversal patterns, stochastic and general Support and Resistance Levels in the price action. These pivot points can be handy but I actually haven’t used them for trade setups and entries myself. I prefer to use candle sticks together with stochastic to determine potential turning points and then take out trades based on these. You can then use the Pivot Points Resistance and Support levels to help you estimate profit targets or areas to start becoming cautious and start tightening your stops. Say, for example, you have gone long from a signal you got a few days ago, you are now in profit and the price is now approaching R2 whilst the Stochastic is approaching overbought, you might want to start tightening your stop loss as you might expect some weakness in the price in the near future. If prices continue up you keep increasing your profits, if prices do reverse then you keep the majority of your existing profits. This would become part of your trade management. If you are after finding potential market turning points and take out trades based on these, then I would suggest using candlestick charting reversal patterns for your trade setups. The patterns I like to use most in my trading can be described as either the Hammer or One White Soldier for Bullish reversals and Shooting Star or One Black Crow for Bearish reversals. Below are diagrams of where to place your entries and exits on both Bullish and Bearish reversal patterns. Bullish Reversal Pattern So after some period of weakness in the price you would look for a bullish day where the price closes above the previous day’s high, you place your buy order here just before market close and place your initial stop just below the low of the day. You would apply this either for an uptrending stock where the price has retracted from or near the trendline or Moving Average, or a ranging stock where price is bouncing off the support line. The trade is reinforced if the Stochastic is in or near the oversold and crossing back upwards, volume on the up day is higher than volume on the down days, and the market as a whole is moving up as well. The benefit with this entry is that you are in early so you capture any bullish move up at the open of the next day, such as gaps. The drawbacks are that you need to be in front of your screen before market close to get your price close to the market close and you may get whipsawed if prices reverse at the open of the next day, thus being stopped out with a small loss. As the price moves up you would move your stop loss to just below the low of each day. Alternative Bullish Reversal Entry An alternative, entry would be to wait for after market close and then start your analysis (easier to do after market close than whilst the market is open and less emotions involved). Place a stop buy order to buy at the open of next trading day just above the high of the bullish green candle. Your stop is placed exactly the same, just below the low of the green bullish candle. The benefits of this alternative entry include you avoid the trade if the price reverses at the open of next day, thus avoiding a potential small loss (in other words you wait for further confirmation on the next trading day), and you avoid trading during market open hours where your emotions can get the better of you. I prefer to do my trading after market close so prefer this alternative. The drawback with this alternative is that you may miss out on bullish news prior to and at the next open, so miss out on some potential profits if prices do gap up at the open. This may also increase your loss on the trade if the prices gaps up then reverses and hits your stop on the same day. However, if you choose this method, then you will just need to incorporate this into your trading plan as potential slippage. Bearish Reversal Pattern So after some short period of strength in the price you would look for a bearish day where the price closes below the previous day’s low, you place your sell short order here just before market close and place your initial stop just above the high of the day. You would apply this either for an downtrending stock where the price has retracted from or near the trendline or Moving Average, or a ranging stock where price is bouncing off the resistance line. The trade is reinforced if the Stochastic is in or near the overbought and crossing back downwards, volume on the up day is higher than volume on the up days, and the market as a whole is moving down as well. The benefit with this entry is that you are in early so you capture any bearish move down at the open of the next day, such as gaps. The drawbacks are that you need to be in front of your screen before market close to get your price close to the market close and you may get whipsawed if prices reverse at the open of the next day, thus being stopped out with a small loss. As the price moves down you would move your stop loss to just above the high of each day. Alternative Bearish Reversal Entry An alternative, entry would be to wait for after market close and then start your analysis (easier to do after market close than whilst the market is open and less emotions involved). Place a stop sell short order to sell at the open of next trading day just below the low of the bearish red candle. Your stop is placed exactly the same, just above the high of the red bearish candle. The benefits of this alternative entry include you avoid the trade if the price reverses at the open of next day, thus avoiding a potential small loss (in other words you wait for further confirmation on the next trading day), and you avoid trading during market open hours where your emotions can get the better of you. I prefer to do my trading after market close so prefer this alternative. The drawback with this alternative is that you may miss out on bearish news prior to and at the next open, so miss out on some potential profits if prices do gap down at the open. This may also increase your loss on the trade if the prices gaps down then reverses and hits your stop on the same day. However, if you choose this method, then you will just need to incorporate this into your trading plan as potential slippage. You could also trade other candle stick patterns is similar ways. And with the long entries you can also use them to get into the market with longer term trend following strategies, you would usually just use a larger stop for longer term trading. To determine the size of your order you would use the price difference between your entry and your stop. You should not be risking more than 1% of your trading capital on any one trade. So if your trading capital is $20,000 your risk per trade should be $200. If you were looking to place your buy at 5.00 and had your initial stop at $4.60, you would divide $200 by $0.40 to get 500 stocks to buy. Using this form of money management you keep your losses down to a maximum of $200 (some trades may be a bit higher due to some slippage which you should allow for in your trading plan), which becomes your R-multiple. Your aim is to have your average win at 3R or higher (3 x your average loss), which will give you a positive expectancy even with a win ratio under 50%. Once you have written down your trading rules you can search stock charts for potential setups. When you find one you can backtest the chart for similar setup over the past few years. For each setup in the past jot down the prices you would have entered at, where you would have set your stop, work out your R, and go day by day, moving your stop as you go, and see where you would have been stopped out. Work out your profit or loss in terms of R for each setup and then add them up. If you get a positive R multiple, then this may be a good stock to trade on this setup. If you get a negative R multiple, then maybe give this stock a miss and look for the next setup. You can setup watch-lists of stocks that perform well for both long setups and short setups, and then trade these stocks when you get a new signal. It can take some time starting off, but once you have got your watch-lists for a particular setup, you just need to keep monitoring those stocks. You can create other watch-lists for other type of setups you have backtested as well.", "title": "" }, { "docid": "468455", "text": "5.3% counts as junk these days?

A lot of people who *think* they would prefer an open and transparent pay-scale (as in unions), change their minds, when placed in one. I have worked in and implemented both types, as both an employee and as an owner/manager. There are pluses and minuses to both. - \"\"Transparent\"\" pay-scale is most effective in a high-turnover, aggressively performance-metric-oriented environment where you expect people to be competing for jobs, including their own job, every day. For example, a pool of commissioned sales-agents: the more you sell, the more you make. Winner gets a Cadillac. Runner-up gets a set of steak knives. Loser gets fired, that kind of thing. If you can't meet your numbers, we let other people start poaching your territory/clients and see what they can do. - Where it doesn't work is in a salary-type position where people are expected to have multiple \"\"soft\"\" duties outside of core performance metrics. The reasons are multi-fold: - One immediate effect of implementing performance-based pay for salary-type employees is that people who are in the office for 8 hours a day, five days a week, immediate start devoting their time and energy towards getting another notch up on the pay-scale, even at the expense of their co-workers, or the company. It intrinsically incentivizes \"\"gaming the system\"\", finding ways to attach your name to easy metrics, and to remove yourself from the most difficult problems. The people who are best at hitting metrics are often not even close to the MVPs. - If instead you take a \"\"soft metrics\"\" or subjective/holistic approach to evaluation, then you get a culture of brown-nosing and office-politics. People start sabotaging the \"\"boss's favorite\"\" and pursuing approval and credit, rather than performance. Instead of fostering a team-oriented, problem-solving approach, it fosters a counter-productive buck-passing, credit-grabbing, and blame-avoidance approach. Note that both of the above intrinsically incentivize risk-avoidance. If you get paid for the number of projects that have your name on them, you find some way to get your name attached to every project, and then move on to the next one, whether the last one was done or not. If you get based on how \"\"successful\"\" the projects bearing your name are, then you avoid anything challenging and make sure only to be attached to the easy ones with the best co-workers. And so on. - Alternately, let's say we keep the same, generic, salary-oriented pay-structure, we just make everyone in a certain \"\"tier\"\" get equal salary, that everyone knows. That sucks all the life out of everyone's sails so fast it will make your head spin: you cannot get a raise for doing a better job, you get paid the same raise as your worst co-worker, every year, for as long as you work here. We will never cut your pay, all you have to do is not be the canary in the coalmine-- so long as you can identify the worst performer in your group, and so long as it's not you, your job is safe. What time do you have to arrive? 5 minutes earlier than the latest-arriving person. How early can you leave? 5 minutes after the earliest one to check out. How much work do you have to get done? Only as much as anyone else is doing. What will you get for being the hardest-working, earliest-to-arrive, latest-to-leave? The same as the worst performer gets: you'll be splitting your raise with him, since we don't credit individuals here, just job-titles. Most jobs that can be easily automated, are automated. If you need a human employee to do it, it's usually because it involves a nontrivial amount of \"\"soft\"\" skills and fuzzy-logic type thinking and behavior. A machine programmed purely to make as many widgets per hour as possible, and motivated to so with human-style skills, ingenuity, and incentives, will tear down the whole factory and dismantle all its co-workers and ignore all quality-controls in order to keep producing widgets. You can't reduce human beings to input-process-output flowcharts (or rather you can, but they will invariably find unintended ways to outsmart your design criteria, with unintended consequences).

You usually need good managers who can identify and motivate good employees, who will feel lucky to have the job and the salary they have, and who will come in every day trying to earn it. Posting everyone's pay on a bulletin-board negates all those \"\"soft\"\" skills, by putting a quantified, black-and-white, relative value on everyone's contribution.

(Regardless of whether your short position is still open or has been closed.) Q: All open shorts which are still open by the settlement date have to be reported by the due date. A: Not exactly. The requirement is that all short positions evaluated based on their settlement dates (rather than their trade dates) still open on the deadline have to be reported by the due date. You sell short 100 AAPL on day 1. You then cover that short by buying 100 AAPL on day 2.

Since your (FINRA member) broker has been told to report based on settlement date, it would report no open position for you in AAPL even though you executed a trade to sell on day 1. The NASDAQ deadline happens to be the end of day 3. Your sell still has not settled, so there's still no open position to report for you. The NASDAQ deadline happens to be the end of day 4.

For example, it makes sense to insure your house against fire; the premium is small compared to the potential damage, which works because the chance of a fire is also small. If you extend a fire insurance to cover dropped glasses, or broken TV sets, it becomes quickly a bad idea - chances for these events are higher, so insurance cost go up (and the events are easier to fake too). Insurance should cover the large damage with low risk, never the small damage with more risk.

Also, as Joe mentioned there are scenarios in which you may be forced to buy the stock (at a higher price than you sold it).

What prevents them from doing that many times a day ? Lack of market. Short selling for short periods of time isn't so common as to allow for \"\"many\"\" times a day. Some day traders may do it occasionally, but I don't know that it would be a reliable business model to supply them. If there are enough people interested in shorting the stock, they will probably want to hold onto it long enough for the anticipated movement to happen. There are transaction costs here. Both fees for trading at all and the extra charges for short sale borrowing and interest. Most stocks do not move down by large enough amounts \"\"many\"\" times a day. Their fluctuations are smaller. If the stock doesn't move enough to cover the transaction fees, then that seller lost money overall.

During the time period that there is no real shares hitting the market, this is called a \"\"naked short\"\". The only legal system that attempts to deter this practice is the \"\"fail to deliver\"\" (FTD) list.

When somebody shorts a stock, it's simply borrowed from another investor's margin; as long as it's not a naked short resulting in an FTD (Failure To Deliver) then it does not add any \"\"artificial\"\" selling pressure. In fact, shorting can actually drive the price up in the long term due to stops and margin calls. Not a guarantee, of course, but if a rally occurs then a high short interest can cause a cascade effect from the short \"\"squeeze\"\", resulting in an even bigger rally than what would have occurred with zero short interest. Many investors actually treat a high short interest as a bullish signal. Compare with margin buying - essentially the opposite of short selling - which has the opposite effect. If investors buy stocks on margin, then if the value of that stock decreases too rapidly they will be forced to sell, which can cause the exact same cascade effect as a short interest but in the opposite direction. Shorting is (in a sense) evening out the odds by inflating the buying pressure at lower stock prices when the borrowers decide to cover and take profits. Bottom line is that, aside from (illegal) insider trading, it doesn't do businesses any good to try to manipulate their stock price or any trading activity. Yes, a company can raise capital by selling additional common shares, but a split really has no effect on the amount of capital they'd be able to raise because it doesn't change the actual market cap, and a dilution is a dilution regardless of the current stock price. If a company's market cap is $1 billion then it doesn't matter if they issue 1 million shares at $50.00 each or 10 million shares at $5.00 each; either way it nets them $50 million from the sale and causes a 5% dilution, to which the market will react accordingly.

The average return on the S&P 500 is about 9.8% (from CNBC) a typical unsecured personal loan will have an interest rate of around 18-36% APR (from NerdWallet). This means that on average you will be paying more interest than you are receiving in returns so are losing money on the margin investment. Sometimes the S&P falls and over those periods you would be paying out interest having lost money so will have a negative return! You may have better credit and so be able to get a lower rate but I don't know your loan terms currently. Secured loans, such as remortgaging your house, will have lower costs but come with more life changing risks. The above assumes that you are getting financing by directly borrowing money, however, it is also possible to trade on margin. This is where you post a proportion of the value that you wish to trade with as collateral against a loan to buy the security. This form of finance is normally used by day traders and other short term holders of stocks. Although the financing costs here are low (I am not charged an interest rate on intraday margin trading) there are very high costs if you exceed the term of the loan. An example is that I am charged a fee if I hold a position overnight and my profits and losses are crystallised at that time. If I am in a losing position at that time the crystallisation process and fee can result in not having enough margin to recover the position and the loss of a potentially profit making position. Additionally if the amount of collateral cash (margin) posted is insufficient to cover the expected losses as calculated by your broker they will initiate a margin call asking for more collateral money. If you do not (or cannot) post this extra margin your losing position will be cashed out and you will take as a loss the total loss at that time. Since the market can change very rapidly, such as in a flash crash, this can result in your losing more money than you had in the first place. As this is essentially a loan you can be bankrupted by this. Overall using leverage to invest magnifies your potential profits but it also magnifies your potential losses. In many cases this magnification could be sufficient to lose you more money than you had originally invested. In addition to magnification you need to consider the cost of finance and that your return over the course of the loan needs to be higher than your cost of finance as well as inflation and other opportunity costs of capital. The S&P 500 is a relatively low volatility market in general so is unlikely to return losses in any given period that will mean that leverage of 1.25 times will take you into losses beyond your own capital investment but it is not impossible. The low level of risk automatically means that your returns are lower and so your cost of capital is likely to be a large proportion of your returns and your returns may not completely cover the cost of capital even when you are making money. The key thing if you are going to trade or invest on leverage is to understand the terms and costs of your leverage and discount them from any returns that you receive before declaring to yourself that you are profitable. It is even more important than usual to know how your positions are doing and whether you are covering your cost of capital when using leverage. It is also very important to know the terms of your leverage in detail, especially what will happen when and if your credit runs out for whatever reason be it the end of the financing period (the length of the loan) or your leverage ratio gets too high. You should also be aware of the costs of closing out the loan early should you need to do so and how to factor that into your investing decisions.", "title": "" } ]

Owning equity in the company is best in situations where you can trade and sell that equity, or where the dilution of your royalty product would affect your returns, or if you can maintain a certain equity stake without working at the company or if you can hold out on taking equity to reinvest profits for the purposes of growth. The royalty is best in situations where you're getting a portion of the gross, since you get paid as a creditor, no matter how the company is performing, or if you intend to collect royalties after you leave the company. Now for your situation: if your royalties are fluctuating with profit instead of gross and your equity is tied to your continued partnership and not subject to potential growth... then they're pretty much both workarounds for the same thing, you've removed the particular advantages for each way of receiving payment. If the company ever does buy out or go public, how much of your additional X earning a month would you have to then re-invest to get an equity stake? And for royalties, if another developer came aboard, or your company bought another company, how much would this dilute your IP contribution?

You can take equity profit as dividend, as long as you're collecting a sufficient salary (this prevents a business from declaring all profits as a dividend).

Should you keep the royalties then go to another job field or retire then your royalties could go on a Schedule E.

Nothing can be \"\"retained\"\" by the company, because as far as the IRS is concerned it doesn't exist, so whether the money from the profits of the company actually made it into your personal checking account or not, it has to be reported by you on the Schedule C. You can elect, if you wish, to have the LLC treated as a corporation; this allows the corporation to retain earnings (and thus to \"\"own\"\" liquid assets like cash, as opposed to only fixed assets like land, cars etc). It also allows you to be an \"\"employee\"\" of your own company, and pay yourself a true \"\"salary\"\", with all the applicable tax rules including pre-tax healthcare, employer-paid FICA, etc. However, the downside here is that some money is subject to double taxation; any monies \"\"retained\"\" by the company, or paid out to members as \"\"dividends\"\", is \"\"profit\"\" of the company for which the company is taxed at the corporate rate. Then, the money from that dividend you receive from the company is taxed again at the capital gains rate on your own 1040 return. This also means that you have to file taxes twice; once for the corporation, once for you as the individual. You can't, of course, have it both ways with an LLC; you can't pay yourself a true \"\"salary\"\" and get the associated tax breaks, then receive leftover profits as a \"\"distribution\"\" and avoid double taxation.

Phage therapy was performed on human subjects in the United States, Europe and Asia in the few decades following their discovery. However, Western countries largely abandoned PT in favour of antibiotics in the 1940s. The relatively recent renaissance of PT in the West can be attributed partly to the increasing prevalence of antibiotic resistance in human and animal pathogens. However, the stringent controls on human trials now required in the United States and Europe have led to a greater number of domestic animal and agricultural applications as an alternative to PT in man. This trend is set to continue, at least in the short term, with recent approval from the Food and Drug Administration allowing commercial phage treatments to be used in human food in the USA. Nevertheless, despite these significant milestones and the growing number of successful PT trials, significant obstacles remain to their widespread use in animals, food and ultimately medicine in many parts of the world.

We estimate that these 14 pathogens cause $14.0 billion (ranging from $4.4 billion to $33.0 billion) in cost of illness and a loss of 61,000 QALYs (ranging from 19,000 to 145,000 QALYs) per year. Roughly 90 % of this loss is caused by five pathogens: nontyphoidal Salmonella enterica ($3.3 billion; 17,000 QALYs), Campylobacter spp. ($1.7 billion; 13,300 QALYs), Listeria monocytogenes ($2.6 billion; 9,400 QALYs), Toxoplasma gondii ($3 billion; 11,000 QALYs), and norovirus ($2 billion; 5,000 QALYs). A companion article attributes losses estimated in this study to the consumption of specific categories of foods. To arrive at these estimates, for each pathogen we create disease outcome trees that characterize the symptoms, severities, durations, outcomes, and likelihoods of health states associated with that pathogen. We then estimate the cost of illness (medical costs, productivity loss, and valuation of premature mortality) for each pathogen. We also estimate QALY loss for each health state associated with a given pathogen, using the EuroQol 5D scale.

This report summarizes 2010 surveillance data and describes trends since 1996. RESULTS: A total of 19,089 infections, 4,247 hospitalizations, and 68 deaths were reported from FoodNet sites in 2010. Salmonella infection was the most common infection reported (17.6 illnesses per 100,000 persons) and was associated with the largest number of hospitalizations (2,290) and deaths (29); no significant change in incidence of Salmonella infection has occurred since the start of surveillance during 1996-1998. Shiga toxin-producing Escherichia coli (STEC) O157 infection caused 0.9 illnesses per 100,000. Compared with 1996-1998, overall incidence of infection with six key pathogens in 2010 was 23% lower, and pathogen-specific incidence was lower for Campylobacter, Listeria, STEC O157, Shigella, and Yersinia infection but higher for Vibrio infection. Compared with a more recent period, 2006--2008, incidence in 2010 was lower for STEC O157 and Shigella infection but higher for Vibrio infection. CONCLUSIONS: The incidence of STEC O157 infection has declined to reach the 2010 national health objective target of ≥1 case per 100,000. This success, as well as marked declines since 1996-1998 in overall incidence of six key foodborne infections, demonstrates the feasibility of preventing foodborne illnesses. IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Salmonella infection should be targeted because it has not declined significantly in more than a decade, and other data indicate that it is one of the most common foodborne infections, resulting in an estimated $365 million in direct medical costs annually. The prevention measures that reduced STEC O157 infection need to be applied more broadly to reduce Salmonella and other infections.

Comparisons of the distal gut microbiota of genetically obese mice and their lean littermates, as well as those of obese and lean human volunteers have revealed that obesity is associated with changes in the relative abundance of the two dominant bacterial divisions, the Bacteroidetes and the Firmicutes. Here we demonstrate through metagenomic and biochemical analyses that these changes affect the metabolic potential of the mouse gut microbiota. Our results indicate that the obese microbiome has an increased capacity to harvest energy from the diet. Furthermore, this trait is transmissible: colonization of germ-free mice with an 'obese microbiota' results in a significantly greater increase in total body fat than colonization with a 'lean microbiota'. These results identify the gut microbiota as an additional contributing factor to the pathophysiology of obesity.", "title": "An obesity-associated gut microbiome with increased capacity for energy harvest." }, { "docid": "MED-3446", "text": "Seaweed and soy foods are consumed daily in Japan, where breast cancer rates for postmenopausal women are significantly lower than in the West.

Recently a strict relationship between histone hyperacetylation in specific tissues of mouse embryos exposed to two HDACi (valproic acid and trichostatin A) and specific axial skeleton malformations has been demonstrated. The aim of this study is to verify if boric acid (BA), that induces in rodents malformations similar to those valproic acid and trichostatin A-related, acts through similar mechanisms: HDAC inhibition and histone hyperacetylation. Pregnant mice were treated intraperitoneally with a teratogenic dose of BA (1000 mg/kg, day 8 of gestation). Western blot analysis and immunostaining were performed with anti hyperacetylated histone 4 (H4) antibody on embryos explanted 1, 3 or 4 h after treatment and revealed H4 hyperacetylation at the level of somites. HDAC enzyme assay was performed on embryonic nuclear extracts. A significant HDAC inhibition activity (compatible with a mixed type partial inhibition mechanism) was evident with BA.

The dietary intake of lignan from flax seed gets converted to enterolactone (EL) and enterodiol in the human system. Here we show that the enterolactone has a very significant anti-metastatic activity as demonstrated by its ability to inhibit adhesion and invasion and migration in MCF-7 and MDA MB231 cell lines. MATERIALS AND METHODS: Migration inhibition assay, actin-based cell motility assay along with reverse transcriptase polymerase chain reaction (RT-PCR) for MMP2, MMP9, MMP11 and MMP14 genes were performed in MCF-7 and MDA MB 231 cell lines. RESULTS: Enterolactone seems to inhibit actin-based cell motility as evidenced by confocal imaging and photo documentation of cell migration assay. The results are supported by the observation that the enterolactone in vitro significantly down-regulates the metastasis-related metalloproteinases MMP2, MMP9 and MMP14 gene expressions. No significant alteration in the MMP11 gene expression was found. CONCLUSIONS: Therefore we suggest that the anti-metastatic activity of EL is attributed to its ability to inhibit cell adhesion, cell invasion and cell motility. EL affects normal filopodia and lamellipodia structures, polymerization of actin filaments at their leading edges and thereby inhibits actin-based cell adhesion and cell motility. The process involves multiple force-generating mechanisms of actin filaments i.e. protrusion, traction, deadhesion and tail-retraction.

Organic products are now sold in specialty stores and conventional supermarkets. Organic products contain numerous marketing claims and terms, only some of which are standardized and regulated. In terms of health advantages, organic diets have been convincingly demonstrated to expose consumers to fewer pesticides associated with human disease. Organic farming has been demonstrated to have less environmental impact than conventional approaches. However, current evidence does not support any meaningful nutritional benefits or deficits from eating organic compared with conventionally grown foods, and there are no well-powered human studies that directly demonstrate health benefits or disease protection as a result of consuming an organic diet. Studies also have not demonstrated any detrimental or disease-promoting effects from an organic diet. Although organic foods regularly command a significant price premium, well-designed farming studies demonstrate that costs can be competitive and yields comparable to those of conventional farming techniques.

Dietary intake was estimated at baseline using a FFQ. BMI was ascertained through baseline self-reported height (1986) and weight (1986, 1992, and 2000). Analyses were based on sex-specific categories of daily total fresh meat, red meat, beef, pork, minced meat, chicken, processed meat, and fish consumption at baseline. Linear mixed effect modeling adjusted for confounders was used to assess longitudinal associations. Significant cross-sectional differences in BMI between quintiles of total meat intake were observed (P-trend < 0.01; both sexes).

Our goal was to evaluate associations between neurocognitive exam scores and a biomarker of cumulative cadmium exposure among adults in the Third National Health and Nutrition Examination Survey (NHANES III). Methods NHANES III is a nationally representative cross-sectional survey of the U.S. population conducted between 1988 and 1994. We analyzed data from a subset of participants, age 20–59, who participated in a computer-based neurocognitive evaluation. There were four outcome measures: the Simple Reaction Time Test (SRTT: visual motor speed), the Symbol Digit Substitution Test (SDST: attention/perception), the Serial Digit Learning Test (SDLT) trials-to-criterion, and the SDLT total-error-score (SDLT-tests: learning recall/short-term memory). We fit multivariable-adjusted models to estimate associations between urinary cadmium concentrations and test scores. Results 5662 participants underwent neurocognitive screening, and 5572 (98%) of these had a urinary cadmium level available. Prior to multivariable-adjustment, higher urinary cadmium concentration was associated with worse performance in each of the 4 outcomes. After multivariable-adjustment most of these relationships were not significant, and age was the most influential variable in reducing the association magnitudes. However among never-smokers with no known occupational cadmium exposure the relationship between urinary cadmium and SDST score (attention/perception) was significant: a 1 μg/L increase in urinary cadmium corresponded to a 1.93% (95%CI: 0.05, 3.81) decrement in performance. Conclusions These results suggest that higher cumulative cadmium exposure in adults may be related to subtly decreased performance in tasks requiring attention and perception, particularly among those adults whose cadmium exposure is primarily though diet (no smoking or work based cadmium exposure). This association was observed among exposure levels that have been considered to be without adverse effects and these levels are common in U.S. adults. Thus further research into the potential neurocognitive effects of cadmium exposure is warranted. Because cumulative cadmium exposure may mediate some of the effects of age and smoking on cognition, adjusting for these variables may result in the underestimation of associations with cumulative cadmium exposure.

In experimental animals, high fat diets result in impaired glucose tolerance. This impairment is associated with decreased basal and insulin-stimulated glucose metabolism. Impaired insulin binding and/or glucose transporters has been related to changes in the fatty acid composition of the membrane induced by dietary fat modification. In humans, high-fat diets, independent of fatty acid profile, have been reported to result in decreased insulin sensitivity. Saturated fat, relative to monounsaturated and polyunsaturated fat, appears to be more deleterious with respect to fat-induced insulin insensitivity. Some of the adverse effects induced by fat feeding can be ameliorated with omega-3 fatty acid. Epidemiological data in humans suggest that subjects with higher intakes of fat are more prone to develop disturbances in glucose metabolism, type 2 diabetes or impaired glucose tolerance, than subjects with lower intakes of fat. Inconsistencies in the data may be attributable to clustering of high intakes of dietary fat (especially animal fat) with obesity and inactivity.

A patient with irritable bowel syndrome (IBS) also has chronic unexplained abdominal pain, and rectal hypersensitivity is observed in a majority of the patients. However, no reports have evaluated the visceral sensory function of FAPS precisely. We aimed to test the hypothesis that FAPS would show altered visceral sensation compared to healthy controls or IBS. The present study determined the rectal perceptual threshold, intensity of sensation using visual analogue scale (VAS), and rectal compliance in response to rectal balloon distention by a barostat in FAPS, IBS, and healthy controls. Methods First, the ramp distention of 40 ml/min was induced and the thresholds of discomfort, pain, and maximum tolerance (mmHg) were measured. Next, three phasic distentions (60-sec duration separated by 30-sec intervals) of 10, 15 and 20 mmHg were randomly loaded. The subjects were asked to mark the VAS in reference to subjective intensity of sensation immediately after each distention. A pressure-volume relationship was determined by plotting corresponding pressures and volumes during ramp distention, and the compliance was calculated over the linear part of the curve by calculating from the slope of the curve using simple regression. Results Rectal thresholds were significantly reduced in IBS but not in FAPS. The VAS ratings of intensity induced by phasic distention (around the discomfort threshold of the controls) were increased in IBS but significantly decreased in FAPS. Rectal compliance was reduced in IBS but not in FAPS.

The FICA taxes are imposed on all workers and self-employed persons. Employers are required[30] to report wages for covered employment to Social Security for processing Forms W-2 and W-3. There are some specific wages which are not a part of the Social Security program (discussed below). Internal Revenue Code provisions section 3101[31] imposes payroll taxes on individuals and employer matching taxes. Section 3102[32] mandates that employers deduct these payroll taxes from workers' wages before they are paid. Generally, the payroll tax is imposed on everyone in employment earning \"\"wages\"\" as defined in 3121[33] of the Internal Revenue Code.[34] and also taxes[35] net earnings from self-employment.[36] **Seriously, you need to learn how to use google asshole.

Here we show that while gilthead sea bream (Sparus aurata) orally challenged with brain homogenates prepared either from a BSE infected cow or from scrapie infected sheep developed no clinical prion disease, the brains of TSE-fed fish sampled two years after challenge did show signs of neurodegeneration and accumulation of deposits that reacted positively with antibodies raised against sea bream PrP. The control groups, fed with brains from uninfected animals, showed no such signs. Remarkably, the deposits developed much more rapidly and extensively in fish inoculated with BSE-infected material than in the ones challenged with the scrapie-infected brain homogenate, with numerous deposits being proteinase K-resistant. These plaque-like aggregates exhibited congophilia and birefringence in polarized light, consistent with an amyloid-like component. The neurodegeneration and abnormal deposition in the brains of fish challenged with prion, especially BSE, raises concerns about the potential risk to public health.

Probiotics may prevent antibiotic-associated diarrhea (AAD) via restoration of the gut microflora. Antibiotics are prescribed frequently in children and AAD is common in this population. OBJECTIVES: To assess the efficacy and adverse effects of probiotics (any specified strain or dose) for the prevention of antibiotic-associated diarrhea in children. To assess adverse events associated with the use of probiotics when co-administered with antibiotics in children. SEARCH STRATEGY: MEDLINE, EMBASE, CENTRAL, CINAHL , AMED, and the Web of Science (inception to August 2006) were searched along with specialized registers including the Cochrane IBD/FBD Review Group, CISCOM, Chalmers PedCAM Research Register and trial registries from inception to 2005. Letters were sent to authors of included trials, nutra/pharmaceutical companies, and experts in the field requesting additional information on ongoing or unpublished trials. Conference proceedings, dissertation abstracts, and reference lists from included and relevant articles were hand searched. SELECTION CRITERIA: Randomized, parallel, controlled (placebo, active, or no treatment) trials comparing co-administered probiotics with antibiotics for the prevention of diarrhea secondary to antibiotic use in children (0 to 18 years). DATA COLLECTION AND ANALYSIS: Methodological quality assessment and data extraction were conducted independently by two authors (BCJ, AS). Dichotomous data (incidence of diarrhea, adverse events) were combined using pooled relative risks, and continuous data (mean duration of diarrhea, mean daily stool frequency) as weighted mean differences, along with their corresponding 95% confidence intervals. Adverse events were summarized using risk difference. For overall pooled results on the incidence of diarrhea, a priori sensitivity analyses included per protocol versus intention to treat, random versus fixed effects, and methodological quality criterion. Subgroup analysis were conducted on probiotic strain, dose, definition of antibiotic-associated diarrhea, and antibiotic agent. MAIN RESULTS: Ten studies met the inclusion criteria. Trials included treatment with either Lactobacilli spp., Bifidobacterium spp., Streptococcus spp., or Saccharomyces boulardii alone or in combination. Six studies used a single strain probiotic agent and four combined two probiotic strains. The per protocol analysis for 9/10 trials reporting on the incidence of diarrhea show statistically significant results favouring probiotics over active/non active controls (RR 0.49; 95% CI 0.32 to 0.74). However, intention to treat analysis showed non-significant results overall (RR 0.90; 95% CI 0.50 to 1.63). Five of ten trials monitored for adverse events (n = 647); none reported a serious adverse event. AUTHORS' CONCLUSIONS: Probiotics show promise for the prevention of pediatric AAD. While per protocol analysis yields treatment effect estimates that are both statistically and clinically significant, as does analysis of high quality studies, the estimate from the intention to treat analysis was not statistically significant. Future studies should involve probiotic strains and doses with the most promising evidence (e.g., Lactobacillus GG, Lactobacillus sporogenes, Saccharomyces boulardii at 5 to 40 billion colony forming units/day). Research done to date does not permit determination of the effect of age (e.g., infant versus older children) or antibiotic duration (e.g., 5 days versus 10 days). Future trials would benefit from a validated primary outcome measure for antibiotic-associated diarrhea that is sensitive to change and reflects what treatment effect clinicians, parents, and children consider important.

Because such exposure may cause adverse health effects, particularly in children, the sources and patterns of exposure need to be studied further. Objectives We assessed young urban/suburban children’s longitudinal exposure to OP pesticides in the Children’s Pesticide Exposure Study (CPES) conducted in the greater Seattle, Washington, area, and used a novel study design that allowed us to determine the contribution of dietary intake to the overall OP pesticide exposure. Methods Twenty-three children 3–11 years of age who consumed only conventional diets were recruited for this 1-year study conducted in 2003–2004. Children switched to organic diets for 5 consecutive days in the summer and fall sampling seasons. We measured specific urinary metabolites for malathion, chlorpyrifos, and other OP pesticides in urine samples collected twice daily for a period of 7, 12, or 15 consecutive days during each of the four seasons. Results By substituting organic fresh fruits and vegetables for corresponding conventional food items, the median urinary metabolite concentrations were reduced to nondetected or close to non-detected levels for malathion and chlorpyrifos at the end of the 5-day organic diet intervention period in both summer and fall seasons. We also observed a seasonal effect on the OP urinary metabolite concentrations, and this seasonality corresponds to the consumption of fresh produce throughout the year.

Advantages: Better at preserving your purchasing power against inflation in the long term (20 years or more, say.) Returns are likely to be higher than stocks or bonds on average.

The first factor is based somewhat in math as it takes into account numbers such as supply and demand, earnings per share, expected earnings, book value, debt ratio and a wide variety of other numbers. You can compile all those numbers into a variety of formulas and come up with a rational estimate of what the stock should sell for. This is all well and good and if the market were entirely rational it would rarely make news because it would be predictable and boring. This is where our second factor throws a wrench in the works. The second factor affecting stock price is emotional. There are many examples of people's emotions affecting stock price but if you would like a good example look up the price fluctuations of Apple (AAPL) after their last couple earnings reports. Numerically their company looks good, their earnings were healthy, their EPS is below average yet their price fell following the report. Why is that? There really isn't a rational reason for it, it is driven by the emotions behind unmet expectations. In a more general sense sometimes price goes down and people get scared and sell causing further decline, sometimes people get excited and see it as opportunity to buy in and the price stabilizes. It is much more difficult to anticipate the reaction the market will have to people's emotional whims which is why predicting stock price with accuracy is near impossible. As a thought along the same line ask yourself this question; if the stock market were entirely rational and price could be predicted with accuracy why is there such a wide range of available strike prices available in the options market? It seems that if stock price could be predicted with anything remotely reassembling accuracy the options market need a much smaller selection of available strike prices.", "title": "" }, { "docid": "446629", "text": "Algorithmic trading essentially banks on the fact that a price will fluctuate in tiny amounts over short periods of time, meaning the volatility is high in that given time frame.

Algorithms become less effective as the time frame increases due to the smoothing effect of volatility over time.

First, as said by CapitalNumb3rs, the dividend yield is the dividends paid in the year as a percent of the stock price. Given this fact then if the stock price moves down and the dividend stays the same then the yield increases. Company's don't usually pay out on a yield basis, that's mostly just a calculation to measure how strong a dividend is. This could mean either A. The stock is underpriced and will rise which will lower the yield to a more normal level or B. the company is not doing as well and eventually the dividends will decrease to a point where the yield again looks more normal. Second off let's look at it in a more realistic way that still takes into account your assumptions: **YEAR 1** 1. Instead of assuming buying 35% let's put this into a share amount. Let's say there are 1,000,000 shares so you just bought 350k shares for $700k. You paid a price of $2/share. Let's assume the market decides that's a fair price and it stays that way through the end of year 1. This gives us a market capitalization of $2 million. 2. The dividend paid out at year 1 is $60k so you could calculate on a per share basis which would be a dividend of $60k / 1 million shares or a $0.06 dividend per share. Our stock price is still at $2.00 so our yield comes out to $0.06 / $2.00 or 3.0% **YEAR 2** Assuming no additional shares issued there are still a total of 1 million shares outstanding. You owned 350k and now want to purchase another 50k (5% of outstanding share float). The market price you are able to purchase the 50k shares at has now changed which means that share price is now valued at $1.50 / share. We have a dividend paid out at $100k, which comes out to a dividend per share of $0.10. We have a share value of $1.50 and the $0.10 dividend per share giving us a new yield of 6.66%. **CONCLUSION:** There are many factors that can cause a company's stock price to fluctuate, some of it is hype based but some of it is a result of material changes. In your case the stock went down 25%. In most scenarios where a stock would have that much decline it would likely either not have been paying a dividend in the first place or would maybe not be paying one for much longer. Most companies that pay dividends are larger and more mature companies with a steady, healthy and predictable cash flow. Also most companies that are that size would not trade a stock under $3.00, I know this is just an example but the scenario is definitely a bit extreme in terms of the price drop and dividend increase. Again the yield is just a calculation that depends on the dividend that is usually planned in advance and the stock price that can fluctuate for many reasons.

Typically, the alternatives are several different mutual funds with different investment styles, e.g. a S&P 500 index fund, a bond fund, a money-market fund, etc. Now, a statement such as \"\"I see my 401k is up 10%\"\" is meaningless unless you tell us how you are making the comparison. For example, if you have just started employment and $200 goes into your 401k each month and is invested in a money-market fund (these are paying close to 0% interest these days), then your 11th contribution increases your 401k from $2000 to $2200 and your 401k is \"\"up 10%\"\". More generally, suppose for simplicity that all the 401k investment is in just one (stock) mutual fund and that you own 100 shares of the fund as of right now. Suppose also that your next contribution will not occur for three weeks when you get your next paycheck, at which time additional shares of the mutual fund will be purchased Now, the value of the mutual fund shares (often referred to as net asset value or NAV) fluctuates as stock prices rise and fall, and so the 401k balance = number of shares times NAV changes in accordance with these fluctuations. So, if the NAV increases by 10% in the next two weeks, your 401k balance will have increased by 10%. But you still own only 100 shares of the mutual fund. You cannot use the 10% increase in value to buy more shares in the mutual fund because there is no money to pay for the additional shares you wish to purchase. Notice that there is no point selling some of the shares (at the 10% higher NAV) to get cash because you will be purchasing shares at the higher NAV too. You could, of course, sell shares of the stock mutual fund at the higher NAV and buy shares of some other fund available to you in the 401k plan. One advantage of doing this inside the 401k plan is that you don't have to pay taxes (now) on the 10% gain that you have made on the sale. Outside tax-deferred plans such as 401k and IRA plans, such gains would be taxable in the year of the sale. But note that selling the shares of the stock fund and buying something else indicates that you believe that the NAV of your stock mutual fund is unlikely to increase any further in the near future. A third possibility for your 401k being up by 10% is that the mutual fund paid a dividend or made a capital gains distribution in the two week period that we are discussing. The NAV falls when such events occur, but if you have chosen to reinvest the dividends and capital gains, then the number of shares that you own goes up. With the same example as before, the NAV goes up 10% in two weeks at which time a capital gains distribution occurs, and so the NAV falls back to where it was before. So, before the capital gains distribution, you owned 100 shares at $10 NAV which went up to $11 NAV (10% increase in NAV) for a net increase in 401k balance from $1000 to $1100. The mutual fund distributes capital gains in the amount of $1 per share sending the NAV back to $10, but you take the $100 distribution and plow it back into the mutual fund, purchasing 10 shares at the new $10 NAV. So now you own 110 shares at $10 NAV (no net change in price in two weeks) but your 401k balance is $1100, same as it was before the capital gains distribution and you are up 10%. Or, you could have chosen to invest the distributions into, say, a bond fund available in your 401k plan and still be up 10%, with no change in your stock fund holding, but a new investment of $100 in a bond fund. So, being up 10% can mean different things and does not necessarily mean that the \"\"return\"\" can be used to buy more shares.\"", "title": "" }, { "docid": "30774", "text": "The biggest challenge with owning any individual stock is price fluctuation, which is called risk. The scenarios you describe assume that the stock behaves exactly as you predict (price/portfolio doubles) and you need to consider risk.

One piece of advice that is often offered to individual investors is to diversify, and the stated reason for diversification is to reduce risk. But that is not telling the whole story. When you are able to identify stocks that are not price correlated, you can construct a portfolio that reduces risk. You are trying to avoid 10% tax on the stock grant (25%-15%), but need to accept significant risk to avoid the 10% differential tax ($1000). An alternative to a single stock is to invest in an ETF (much lower risk), which you can buy and hold for a long time, and the price/growth of an ETF (ex. SPY) can be charted versus your stock to visualize the difference in growth/fluctuation. Look up the beta (volatility) of your stock compared to SPY (for example, IBM). Compare the beta of IBM and TSLA and note that you may accept higher volatility when you invest in a stock like Tesla over IBM. What is the beta of your stock? And how willing are you to accept that risk? When you can identify stocks that move in opposite directions, and mix your portfolio (look up beta balanced portolio), you can smooth out the variability (reduce the risk), although you may reduce your absolute return. This cannot be done with a single stock, but if you have more money to invest you could compose the rest of your portfolio to balance the risk for this stock grant, keep the grant shares, and still effectively manage risk.

You can have bond or mixed ETFs. You can even get ETFs with equal or fundamental weighting. In short, all the variety benefits of mutual funds. ETFs are typically much less expensive than mutual funds both in terms of management fees (expense ratio) and taxable gains. Most of them are not actively managed; instead they follow an index and therefore have a low turnover. A mutual fund may actively trade and, if not balanced with a loss, will generate capital gains that you pay taxes on. An ETF will produce gains only when shifting to keep inline with the index or you yourself sell. As a reminder: while expense ratio always matters, capital gains and dividends don't matter if the ETF or mutual fund is in a tax-advantaged account. ETFs have no load fees. Instead, because you trade it like a stock, you will pay a commission. Commissions are straight, up-front and perfectly clear. Much easier to understand than the various ways funds might charge you. There are no account minimums to entry with ETFs, but you will need to buy complete shares. Only a few places allow partial shares. It is generally harder to dollar-cost average into an ETF with regular automated investments. Also, like trading stocks, you can do those fancy things like selling short, buying on margin, options, etc. And you can pay attention to the price fluctuations throughout the day if you really want to.

LEAPs don't react 1:1 with a stock move because the probability of your option being in the money at expiry is still very much up in the air so you basically don't get full credit for a move in the stock this far out from expiry. The more complex answer involves a discussion of option 'greeks'. Delta, Gamma, Theta, Vega, and Rho are variables that affect the pricing of all options. The key greek in this case is Delta because it describes mathematically the expected move of an option as a ratio vs changes in stock price. For put options the ratio is -1 to 0 where -1 is direct correlation between stock price and option price and 0 is no correlation. The Delta increases as an option gets deeper in the money and also as it gets closer to expiry and reflects the probability of the option expiring in the money. For your option contract the current Delta is -0.5673 so -3.38 * -0.5673 = 1.9 which is close. Also keep in mind that that strike price had a last trade at 12:03 when the stock was at 13.3 and the current ask price is 22.30 so the last price isn't a true reflection of the market value. As for the other greeks, Gamma is a reflection of volatility in the sense that it affects the rate of change of Delta as price and time changes. Theta is the value of the time component of the option and is expressed as the expected time decay per day. The problem is that the time premium is really some arbitrary number that the market maker seems to be able to change at will without justification and it can fluctuate wildly over short periods of time and I think this may explain some of the discrepancy. If you bought the options when AAPL was $118.68 a couple weeks ago (option price of $18.85) and now AAPL is at $112.34 and the Delta over that time averaged at -0.55 then your expected option price would be $22.34 (($118.68 - $112.34) * 0.55 + 18.85 = $22.34) so you lost around $0.24 in time premium or 'Theta burn' over the last 2 weeks assuming it opens trading around 22.1 on Monday. Your broker should have information about the option contract greeks somewhere. For my platform I have to put the cursor over top of the option contract for it to show me the greeks. If your broker doesn't have this then you can get it from nasdaq.com. This is another reason that I only invest in deep in the money LEAPs because the time premium is much much lower than near the money and also because delta is much higher so if I want to trade out of it early I don't feel like I'm getting ripped off not getting paid for a stock price move. For example look at the Jan 17 175 put. The Delta is -0.9 and the time premium is only $0-1 depending if you are looking at the bid or ask.

Those who are trading options or using some short-term strategies could get screwed because of the sudden volatility. My next point is related to the above. What is the intrinsic value of a stock? The current price of a stock is the equilibrium of all investor's perception of the stock's value. Professionals make up a value for a stock using models such as DCF. Once they do so they trade based on what they believe the value of the stock is.

Look at Tesla, Netflix, or just google momentum stocks. All the big crashes in stock prices happen when these big funds unload their stocks. A surge in supply will cut the price. The problem is you can't predict when some fund manager will decide to sell some stake of his. Tying everything together is liquidity.

Even if that account had access to a wide variety of funds, it still might not be worth the added hassle or trading costs of owning and rebalancing multiple funds inside the smaller account. There, perhaps, the life cycle fund can help you out, while you use your own strategy in your main account. Finally, let's assume you had a single main account and you buy partially into the idea of a life cycle fund and you find a great one with low fees. Except: you want a bit of something else in your portfolio not provided by the life cycle fund, e.g. some more emerging markets, international, or commodity stock exposure. (Is this one reason you're doing it yourself?) In that case, where the life cycle fund doesn't quite have everything you want, you could still use it for the bulk of the portfolio (e.g. 85-95%) and then select one or two specific additional ETFs to complement it. Just make sure you factor in those additional components into the overall equity weighting and adjust your life cycle fund choice accordingly (e.g. perhaps go more conservative in the life cycle, to compensate.) I hope that helps!

That's why single-stock options are far more liquid than single-stock futures. However, if you are a farmer with a huge mortgage depending upon the chaos of agricultural markets which are extremely volatile, a different structure might appeal to you. You could long your inputs while shorting your outputs, locking in a profit. That profit is probably lower than what one could expect over the long run without hedging, but it will surely be less volatile. Here's where the advantage of futures come in for that kind of structure: the margin on the longs and shorts can offset each other, forcing the farmer to have to put up much less of one's own money to hedge. With options, this is not the case. Also, the gross margin between the inputs rarely fluctuate to an unmanageable degree, so if your shorts rise faster than your longs, you'll only have to post margin in the amount of the change in the net of the longs and shorts.

It is a contract where the final value depends on (is derived from) the value of something else. Stock, for instance, is not a derivative because the contract itself is actually ownership of part of a company. Whereas car insurance is a derivative because the payout depends on the value of something else namely your (and other peoples') cars. The problem with such a simple definition is that it covers such a broad class. It covers simple contracts like Futures where the end value just depends on the price of something on a future date. But it extends to contracts complicated enough that people in finance call them Exotics. Derivatives are broadly used for two things reducing risk (sometimes called insurance) and speculation. A farmer can use derivatives to make sure she gets paid a certain amount for her corn. A banker can group a bunch of loans together and sell slices to reduce the pain of a particular loan failing. At the same time people can use the same instruments to speculate on the price of (for example) that corn or those loans and the main advantage is that they don't have to buy the corn or loans directly. Any farmer will tell you corn can be very expensive to store. Derivatives generally cause problems both individually and sometimes world wide when people don't properly understand the risks involved. The most famous example being Mortgage-backed Securities and the recent Great Recession. You can start understand the instruments and their risks by this wonderful Wikipedia article and later perhaps a used collection of CFA books which cover derivatives in great detail.

It doesn't necessarily mean more fluctuation and in the real world, it often means that these are well-understood stocks with a high amount of analyst coverage. This tends towards these stocks not being as volatile as smaller stocks with less liquidity. Company revenue (and profit) will help an investor predict company growth. That is one factor in a stock price. There are certain stocks that you would buy without them making a profit because their future revenue looks potentially explosive.

While some investors may buy stocks in the hope that they will be able to find other people willing to pay more for the stock than they did, that's a zero sum game. The only way investors can make money in the aggregate is if either stocks pay dividends or if the money paid for company assets at liquidation exceeds total net price for which the company sold shares. One advantage of dividends from a market-rationality perspective is that dividend payments are easy to evaluate than company value. Ideally, the share price of a company should match the present per-share cash value of all future dividends and liquidation, but it's generally impossible to know in advance what that value will be. Stock prices may sometimes rise because of factors which increase the expected per-share cash value of future dividends and liquidations. In a sane market, rising prices on an item will reduce people's eagerness to buy and increase people's eagerness to sell. Unfortunately, in a marketplace where steady price appreciation is expected the feedback mechanisms responsible for stability get reversed. Rapidly rising prices act as a red flag to buyers--unfortunately, bulls don't see red flags as signal to stop, but rather as a signal to charge ahead. For a variety of reasons including the disparate treatment of dividends and capital gains, it's often not practical for a company to try to stabilize stock prices through dividends and stock sales. Nonetheless, dividends are in a sense far more \"\"real\"\" than stock price appreciation, since paying dividends generally requires that companies actually have sources of revenues and profits.

X issues a quarterly dividend of $1 per share and the share price is $100; coincidentally this is the price at which you purchased your shares.

First, as the commenters above have already said, the log-return from one period is log(price at time t/price at time t-1) which is approximately equal to the percentage change in the price from time t-1 to time t, provided that this percentage change is not big compared to the size of the price. (Note that you have to use the natural log, ie. log to the base e -- ln button on a calculator -- here.) The main use of the log-return is that is a proxy for the percentage change in the price, which turns out to be mathematically convenient, for various reasons which have mostly already been mentioned in the comments. But you already know this; your actual question is about the average log-return over a period of time. What does this indicate about the stock? The answer is: if the stock price is not changing very much, then the average log-return is about equal to the average percentage change in the price, and is very easy and quick to calculate. But if the stock price is very volatile, then the average log-return can be wildly different to the average percentage change in the price. Here is an example: the closing prices for Pitchfork Oil from last week's trading are: 10, 5, 12, 5, 10, 2, 15. The percentage changes are: -0.5, 1.4, -0.58, 1, -0.8, 6.5 (where -0.5 means -50%, etc.) The average percentage change is 1.17, or 117%. On the other hand, the log-returns for the same period are -0.69, 0.88, -0.88, 0.69, -1.6, 2, and the average log-return is about 0.068. If we used this as a proxy for the average percentage change in the price over the whole seven days, we would get 6.8% instead of 117%, which is wildly wrong. The reason why it is wrong is because the price fluctuated so much. On the other hand, the closing prices for United Marshmallow over the same period are 10, 11, 12, 11, 12, 13, 15. The average percentage change from day to day is 0.073, and the average log-return is 0.068, so in this case the log-return is very close to the percentage change. And it has the advantage of being computable from just the first and last prices, because the properties of logarithms imply that it simplifies to (log(15)-log(10))/6. Notice that this is exactly the same as for Pitchfork Oil. So one reason why you might be interested in the average log-return is that it gives a very quick way to estimate the average return, if the stock price is not changing very much. Another, more subtle reason, is that it actually behaves better than the percentage return. When the price of Pitchfork jumps from 5 to 12 and then crashes back to 5 again, the percentage changes are +140% and -58%, for an average of +82%. That sounds good, but if you had bought it at 5, and then sold it at 5, you would actually have made 0% on your money. The log-returns for the same period do not have this disturbing property, because they do add up to 0%. What's the real difference in this example? Well, if you had bought $1 worth of Pitchfork on Tuesday, when it was 5, and sold it on Wednesday, when it was 12, you would have made a profit of $1.40. If you had then bought another $1 on Wednesday and sold it on Thursday, you would have made a loss of $0.58. Overall, your profit would have been $0.82. This is what the average percentage return is calculating. On the other hand, if you had been a long-term investor who had bought on Tuesday and hung on until Thursday, then quoting an \"\"average return\"\" of 82% is highly misleading, because it in no way corresponds to the return of 0% which you actually got! The moral is that it may be better to look at the log-returns if you are a buy-and-hold type of investor, because log-returns cancel out when prices fluctuate, whereas percentage changes in price do not. But the flip-side of this is that your average log-return over a period of time does not give you much information about what the prices have been doing, since it is just (log(final price) - log(initial price))/number of periods. Since it is so easy to calculate from the initial and final prices themselves, you commonly won't see it in the financial pages, as far as I know. Finally, to answer your question: \"\"Does knowing this single piece of information indicate something about the stock?\"\", I would say: not really. From the point of view of this one indicator, Pitchfork Oil and United Marshmallow look like identical investments, when they are clearly not. Knowing the average log-return is exactly the same as knowing the ratio between the final and initial prices.\"", "title": "" }, { "docid": "484778", "text": "\"There are a few reason why the stock price decreases after a dividend is paid: What's the point of paying a dividend if the stock price automatically decreases? Don't the shareholders just break even? Companies have to do something with their profits. They beholden to their shareholders to make them money either by increasing the share value or paying dividends. So they have the choice between reinvesting their profits into the company to grow the business or just handing the profits directly to the owners of the business (the shareholders). Some companies are as big as they want to be and investing their profits into more capital offers them diminishing returns. These companies are more likely to pay dividends to their shareholders. I assume the price of the stock \"\"naturally\"\" increases over the year to reflect the amount of the dividend payment. This is kind of a vague question but then doesn't it make it difficult to evaluate the fluctuations in stock price (in the way that you would a company that doesn't pay a dividend)? It depends on the company. The price may recover the dividend drop... could take a few days to a week. And that dependings on the company's performance and the overall market performance. With respect to options, I assume nothing special happens? So say I bought $9 call options yesterday that were in the money, all of a sudden they're just not? Is this typically priced into the option price? Is there anything else I need to know about buying options in companies that pay dividends? What if I had an in-the-money option, and all of a sudden out of nowhere a company decides to pay a dividend for the first time. Am I just screwed? One key is that dividends are announced in advance (typically at least, if not always; not sure if it's required by law but I wouldn't be surprised). This is one reason people will sometimes exercise a call option early, because they want to get the actual stock in order to earn the dividend. For \"\"out of the ordinary\"\" large cash dividends (over 10% is the guideline), stock splits, or other situations an option can be adjusted: http://www.888options.com/help/faq/splits.jsp#3 If you have an options account, they probably sent you a \"\"Characteristics and Risks of Standardized Options\"\" booklet. It has a section discussing this topic and the details of what kinds of situations trigger an adjustment. A regular pre-announced <10% dividend does not, while a special large dividend would, is what I roughly get from it. That \"\"Characteristics and Risks of Standardized Options\"\" is worth reading by the way; it's long and complicated, but well, options are complicated. Finally, do all companies reduce their stock price when they pay a dividend? Are they required to? I'm just shocked I've never heard of this before. The company doesn't directly control the stock price, but I do believe this is automatic. I think the market does this automatically because if they didn't, there would be enough people trying to do dividend capture arbitrage that it would ultimately drive down the price.\"", "title": "" } ]

METHODS: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, Hoechst 33258 nuclear staining and Boyden transwell chamber methods were used to determine whether purified sweet potato protein (SPP) from fresh sweet potato roots affected proliferation, migration and invasion, respectively, of human colorectal cancer SW480 cells in vitro. The inhibitory effects of SPP on growth of human colorectal cancer HCT-8 cells intraperitoneally xenografted in nude mice and spontaneous lung metastasis of murine Lewis lung carcinoma 3LL cells subcutaneously transplanted in C57 BL/6 mice were also investigated in vivo. RESULTS: SPP inhibited the proliferation of SW480 cells in a dose-dependent manner, with an IC50 value of 38.732 μmol/L (r2 = 0.980, P = 0.003) in the MTT assay. Hoechst 33258 nuclear staining further revealed inhibition of cell viability and induction of apoptosis by SPP.

Previous reports have suggested an association between gout and kidney stone disease; however, these studies did not adjust for such important potential confounders as obesity and the presence of hypertension. To our knowledge, no published study has examined the independent association between gout and kidney stone disease. METHODS: We used a national probability sample of the US population to determine the independent association between reported gout and history of kidney stone disease. RESULTS: Among men and women 20 years and older, 5.6% (10 million) reported the previous passage of a kidney stone and 2.7% (5.1 million) reported a diagnosis of gout by a physician. Moreover, 8.6% of individuals who reported the passage of a kidney stone on two or more occasions had a history of gout. Conversely, the prevalence of previous kidney stones in subjects with reported gout was 13.9%. In the age-adjusted model, gout was associated with an increased odds ratio (OR) for previous kidney stones (OR, 1.97; 95% confidence interval [CI], 1.37 to 2.83). After further adjustment for sex, race, body mass index, and presence of hypertension, the OR for previous kidney stones in individuals with gout decreased to 1.49 (95% CI, 1.04 to 2.14).

Later, \"ipomoein\" was renamed \"sporamin\" and was found to be a major storage protein that accounted for over 80% of the total protein in the tuberous root. To date, sporamin has been studied by a series of biochemical and molecular approaches. The first purification of sporamin into two major fractions, A and B, was successfully completed in 1985. Several characteristics of the protein, such as the diversification of the nucleotide sequences in the gene family, the protein structure, the biological functions of storage, defense, inhibitory activity and ROS scavenging, were identified. In the past decade, sporamin was classified as a Kunitz-type trypsin inhibitor, and its insect-resistance capability has been examined in transgenic tobacco and cauliflower plants, indicating the multiple functions of this protein has evolved to facilitate the growth and development of sweet potato. Sporamin is constitutively expressed in the tuberous root and is not normally expressed in the stem or leaves. However, this protein is expressed systemically in response to wounding and other abiotic stresses. These dual expression patterns at the transcriptional level revealed that the complex regulatory mechanism of sporamin was modulated by environmental stresses. The versatile functions of sporamin make this storage protein a good research model to study molecular evolution, regulatory mechanisms and physiological functions in plants.

RESULTS: We have defined normal bowel habit and transit time, identified their role as risk factors for disease and how they may be measured. Similarly, we have tried to define what is a healthy gut flora in terms of the dominant genera and their metabolism and listed the many, varied and novel methods for determining these parameters.

Deaths from zoonotic bacterial diseases, helminthiasis, myasthenia gravis, schizophrenia, other diseases of the spinal cord, diseases of the esophagus and peritonitis were non-significantly elevated overall by all analyses, and significantly so in particular race/sex subgroups.

Interventions: N/A. Measurements and Results: During a median follow-up of 14.3 years, there were 1964 deaths (men and women: 1038 and 926) from stroke, 881 (508 and 373) from coronary heart disease, 4287 (2297 and 1990) from cardiovascular disease, 5465 (3432 and 2033) from cancer, and 14,540 (8548 and 5992) from all causes. Compared with a sleep duration of 7 hours, sleep duration of 4 hours or less was associated with increased mortality from coronary heart disease for women and noncardiovascular disease/noncancer and all causes in both sexes. The respective multivariable hazard ratios were 2.32 (1.19–4.50) for coronary heart disease in women, 1.49 (1.02–2.18) and 1.47 (1.01–2.15) for noncardiovascular disease/noncancer, and 1.29 (1.02–1.64) and 1.28 (1.03–1.60) for all causes in men and women, respectively. Long sleep duration of 10 hours or longer was associated with 1.5- to 2-fold increased mortality from total and ischemic stroke, total cardiovascular disease, noncardiovascular disease/noncancer, and all causes for men and women, compared with 7 hours of sleep in both sexes. There was no association between sleep duration and cancer mortality in either sex. Conclusions: Both short and long sleep duration were associated with increased mortality from cardiovascular disease, noncardiovascular disease/noncancer, and all causes for both sexes, yielding a U-shaped relationship with total mortality with a nadir at 7 hours of sleep.

This cohort study on 3932 men and women was based on data from the Finnish Mobile Clinic Health Examination Survey, conducted in 1968-72. The participants were 40-74 years of age and free of cardiovascular diseases at baseline. Data on the plant food consumption were derived from a 1-year dietary history interview.

The population-attributable proportion of chronic disease associated with current patterns of artificial feeding in infancy is estimated. RESULTS: After adjustment for major confounding variables, current research suggests that the risks of chronic disease are 30-200 % higher in those who were not breast-fed compared to those who were breast-fed in infancy. Exposure to premature weaning ranges from 20 % to 90 % in post-World War II age cohorts.

The objective of this work was to examine the association between PCB levels in post-mortem human brain tissue and the diagnosis of Parkinson’s disease, as well as the degree of nigral depigmentation. We also sought to determine if this association was more significant when patients were stratified by sex. Post-mortem brain samples from control patients and those diagnosed with Parkinson’s disease were obtained from the Emory University Brain Bank and from the Nun Study. Concentrations of eight prevalent PCB congeners were extracted from post-mortem brain tissue and analyzed using gas chromatography-mass spectrometry. PCB congeners 153 and 180 were significantly elevated in the brains of Parkinson’s disease patients. When stratified by sex, the female Parkinson’s disease group demonstrated significantly elevated concentrations of total PCBs and specifically congeners 138, 153, and 180 compared to controls, whereas PCB concentrations in males were not significantly different between control and Parkinson’s disease groups.

No complete revision of global disease burden caused by risk factors has been done since a comparative risk assessment in 2000, and no previous analysis has assessed changes in burden attributable to risk factors over time. Methods We estimated deaths and disability-adjusted life years (DALYs; sum of years lived with disability [YLD] and years of life lost [YLL]) attributable to the independent effects of 67 risk factors and clusters of risk factors for 21 regions in 1990 and 2010. We estimated exposure distributions for each year, region, sex, and age group, and relative risks per unit of exposure by systematically reviewing and synthesising published and unpublished data. We used these estimates, together with estimates of cause-specific deaths and DALYs from the Global Burden of Disease Study 2010, to calculate the burden attributable to each risk factor exposure compared with the theoretical-minimum-risk exposure. We incorporated uncertainty in disease burden, relative risks, and exposures into our estimates of attributable burden. Findings In 2010, the three leading risk factors for global disease burden were high blood pressure (7·0% [95% uncertainty interval 6·2–7·7] of global DALYs), tobacco smoking including second-hand smoke (6·3% [5·5–7·0]), and alcohol use (5·5% [5·0–5·9]). In 1990, the leading risks were childhood underweight (7·9% [6·8–9·4]), household air pollution from solid fuels (HAP; 7·0% [5·6–8·3]), and tobacco smoking including second-hand smoke (6·1% [5·4–6·8]). Dietary risk factors and physical inactivity collectively accounted for 10·0% (95% UI 9·2–10·8) of global DALYs in 2010, with the most prominent dietary risks being diets low in fruits and those high in sodium. Several risks that primarily affect childhood communicable diseases, including unimproved water and sanitation and childhood micronutrient deficiencies, fell in rank between 1990 and 2010, with unimproved water we and sanitation accounting for 0·9% (0·4–1·6) of global DALYs in 2010. However, in most of sub-Saharan Africa childhood underweight, HAP, and non-exclusive and discontinued breastfeeding were the leading risks in 2010, while HAP was the leading risk in south Asia. The leading risk factor in Eastern Europe, most of Latin America, and southern sub-Saharan Africa in 2010 was alcohol use; in most of Asia, North Africa and Middle East, and central Europe it was high blood pressure. Despite declines, tobacco smoking including second-hand smoke remained the leading risk in high-income north America and western Europe. High body-mass index has increased globally and it is the leading risk in Australasia and southern Latin America, and also ranks high in other high-income regions, North Africa and Middle East, and Oceania. Interpretation Worldwide, the contribution of different risk factors to disease burden has changed substantially, with a shift away from risks for communicable diseases in children towards those for non-communicable diseases in adults. These changes are related to the ageing population, decreased mortality among children younger than 5 years, changes in cause-of-death composition, and changes in risk factor exposures. New evidence has led to changes in the magnitude of key risks including unimproved water and sanitation, vitamin A and zinc deficiencies, and ambient particulate matter pollution. The extent to which the epidemiological shift has occurred and what the leading risks currently are varies greatly across regions. In much of sub-Saharan Africa, the leading risks are still those associated with poverty and those that affect children.

OBJECTIVES: To measure the burden of diseases, injuries, and leading risk factors in the United States from 1990 to 2010 and to compare these measurements with those of the 34 countries in the Organisation for Economic Co-operation and Development (OECD) countries. DESIGN: We used the systematic analysis of descriptive epidemiology of 291 diseases and injuries, 1160 sequelae of these diseases and injuries, and 67 risk factors or clusters of risk factors from 1990 to 2010 for 187 countries developed for the Global Burden of Disease 2010 Study to describe the health status of the United States and to compare US health outcomes with those of 34 OECD countries. Years of life lost due to premature mortality (YLLs) were computed by multiplying the number of deaths at each age by a reference life expectancy at that age. Years lived with disability (YLDs) were calculated by multiplying prevalence (based on systematic reviews) by the disability weight (based on population-based surveys) for each sequela; disability in this study refers to any short- or long-term loss of health. Disability-adjusted life-years (DALYs) were estimated as the sum of YLDs and YLLs. Deaths and DALYs related to risk factors were based on systematic reviews and meta-analyses of exposure data and relative risks for risk-outcome pairs. Healthy life expectancy (HALE) was used to summarize overall population health, accounting for both length of life and levels of ill health experienced at different ages. RESULTS: US life expectancy for both sexes combined increased from 75.2 years in 1990 to 78.2 years in 2010; during the same period, HALE increased from 65.8 years to 68.1 years. The diseases and injuries with the largest number of YLLs in 2010 were ischemic heart disease, lung cancer, stroke, chronic obstructive pulmonary disease, and road injury. Age-standardized YLL rates increased for Alzheimer disease, drug use disorders, chronic kidney disease, kidney cancer, and falls. The diseases with the largest number of YLDs in 2010 were low back pain, major depressive disorder, other musculoskeletal disorders, neck pain, and anxiety disorders. As the US population has aged, YLDs have comprised a larger share of DALYs than have YLLs. The leading risk factors related to DALYs were dietary risks, tobacco smoking, high body mass index, high blood pressure, high fasting plasma glucose, physical inactivity, and alcohol use. Among 34 OECD countries between 1990 and 2010, the US rank for the age-standardized death rate changed from 18th to 27th, for the age-standardized YLL rate from 23rd to 28th, for the age-standardized YLD rate from 5th to 6th, for life expectancy at birth from 20th to 27th, and for HALE from 14th to 26th. CONCLUSIONS AND RELEVANCE: From 1990 to 2010, the United States made substantial progress in improving health. Life expectancy at birth and HALE increased, all-cause death rates at all ages decreased, and age-specific rates of years lived with disability remained stable.

The efficacy of curcumin in several pre-clinical trials for neurodegenerative diseases has created considerable excitement mainly due to its lack of toxicity and low cost. This suggests that curcumin could be a worthy candidate for nutraceutical intervention. Since aging is a common risk factor for neurodegenerative diseases, it is possible that some compounds that target aging mechanisms could also prevent these kinds of diseases.

In the Global Burden of Diseases, Injuries, and Risk Factors Study 2010 (GBD 2010), we aimed to estimate annual deaths for the world and 21 regions between 1980 and 2010 for 235 causes, with uncertainty intervals (UIs), separately by age and sex. METHODS: We attempted to identify all available data on causes of death for 187 countries from 1980 to 2010 from vital registration, verbal autopsy, mortality surveillance, censuses, surveys, hospitals, police records, and mortuaries. We assessed data quality for completeness, diagnostic accuracy, missing data, stochastic variations, and probable causes of death. We applied six different modelling strategies to estimate cause-specific mortality trends depending on the strength of the data. For 133 causes and three special aggregates we used the Cause of Death Ensemble model (CODEm) approach, which uses four families of statistical models testing a large set of different models using different permutations of covariates. Model ensembles were developed from these component models. We assessed model performance with rigorous out-of-sample testing of prediction error and the validity of 95% UIs. For 13 causes with low observed numbers of deaths, we developed negative binomial models with plausible covariates. For 27 causes for which death is rare, we modelled the higher level cause in the cause hierarchy of the GBD 2010 and then allocated deaths across component causes proportionately, estimated from all available data in the database. For selected causes (African trypanosomiasis, congenital syphilis, whooping cough, measles, typhoid and parathyroid, leishmaniasis, acute hepatitis E, and HIV/AIDS), we used natural history models based on information on incidence, prevalence, and case-fatality. We separately estimated cause fractions by aetiology for diarrhoea, lower respiratory infections, and meningitis, as well as disaggregations by subcause for chronic kidney disease, maternal disorders, cirrhosis, and liver cancer. For deaths due to collective violence and natural disasters, we used mortality shock regressions. For every cause, we estimated 95% UIs that captured both parameter estimation uncertainty and uncertainty due to model specification where CODEm was used. We constrained cause-specific fractions within every age-sex group to sum to total mortality based on draws from the uncertainty distributions. FINDINGS: In 2010, there were 52·8 million deaths globally. At the most aggregate level, communicable, maternal, neonatal, and nutritional causes were 24·9% of deaths worldwide in 2010, down from 15·9 million (34·1%) of 46·5 million in 1990. This decrease was largely due to decreases in mortality from diarrhoeal disease (from 2·5 to 1·4 million), lower respiratory infections (from 3·4 to 2·8 million), neonatal disorders (from 3·1 to 2·2 million), measles (from 0·63 to 0·13 million), and tetanus (from 0·27 to 0·06 million). Deaths from HIV/AIDS increased from 0·30 million in 1990 to 1·5 million in 2010, reaching a peak of 1·7 million in 2006. Malaria mortality also rose by an estimated 19·9% since 1990 to 1·17 million deaths in 2010. Tuberculosis killed 1·2 million people in 2010. Deaths from non-communicable diseases rose by just under 8 million between 1990 and 2010, accounting for two of every three deaths (34·5 million) worldwide by 2010. 8 million people died from cancer in 2010, 38% more than two decades ago; of these, 1·5 million (19%) were from trachea, bronchus, and lung cancer. Ischaemic heart disease and stroke collectively killed 12·9 million people in 2010, or one in four deaths worldwide, compared with one in five in 1990; 1·3 million deaths were due to diabetes, twice as many as in 1990. The fraction of global deaths due to injuries (5·1 million deaths) was marginally higher in 2010 (9·6%) compared with two decades earlier (8·8%). This was driven by a 46% rise in deaths worldwide due to road traffic accidents (1·3 million in 2010) and a rise in deaths from falls. Ischaemic heart disease, stroke, chronic obstructive pulmonary disease (COPD), lower respiratory infections, lung cancer, and HIV/AIDS were the leading causes of death in 2010. Ischaemic heart disease, lower respiratory infections, stroke, diarrhoeal disease, malaria, and HIV/AIDS were the leading causes of years of life lost due to premature mortality (YLLs) in 2010, similar to what was estimated for 1990, except for HIV/AIDS and preterm birth complications. YLLs from lower respiratory infections and diarrhoea decreased by 45-54% since 1990; ischaemic heart disease and stroke YLLs increased by 17-28%. Regional variations in leading causes of death were substantial. Communicable, maternal, neonatal, and nutritional causes still accounted for 76% of premature mortality in sub-Saharan Africa in 2010. Age standardised death rates from some key disorders rose (HIV/AIDS, Alzheimer's disease, diabetes mellitus, and chronic kidney disease in particular), but for most diseases, death rates fell in the past two decades; including major vascular diseases, COPD, most forms of cancer, liver cirrhosis, and maternal disorders. For other conditions, notably malaria, prostate cancer, and injuries, little change was noted. INTERPRETATION: Population growth, increased average age of the world's population, and largely decreasing age-specific, sex-specific, and cause-specific death rates combine to drive a broad shift from communicable, maternal, neonatal, and nutritional causes towards non-communicable diseases. Nevertheless, communicable, maternal, neonatal, and nutritional causes remain the dominant causes of YLLs in sub-Saharan Africa. Overlaid on this general pattern of the epidemiological transition, marked regional variation exists in many causes, such as interpersonal violence, suicide, liver cancer, diabetes, cirrhosis, Chagas disease, African trypanosomiasis, melanoma, and others. Regional heterogeneity highlights the importance of sound epidemiological assessments of the causes of death on a regular basis. FUNDING: Bill & Melinda Gates Foundation.

The objective of this study was to determine whether detection of childhood celiac disease by mass screening improves long-term health status and health-related quality of life. METHODS: We conducted a prospective 10-year follow-up study of 32 children who were aged 2 to 4 years, had celiac disease identified by mass screening, and had a gluten-free diet (19) or a normal gluten-containing diet (13). The follow-up included assessments of general health status, celiac disease-associated symptoms, celiac disease-associated serum antibodies, and health-related quality of life. RESULTS: Ten years after mass screening, 81% of the children were adhering to a gluten-free diet. The health status improved in 66% of the treated children: in 41% by early treatment and in 25% by prevention of the gluten-dependent symptoms that they developed after diagnosis. For 19% of the children, treatment after screening would not have improved their health status, because they had no symptoms at screening and have remained symptom-free while consuming gluten. The health-related quality of life of the children with symptoms improved significantly after 1 year of gluten-free diet. Ten years after screening, the health-related quality of life of the children with celiac disease was similar to that of the reference population. CONCLUSION: Identification by mass screening led 10 years later to health improvement in 66% of children without deterioration of generic health-related quality of life. There is a good compliance after mass screening. In a research setting, delaying treatment for children without symptoms seems to be an option after a positive screening test.

Allergic diseases, particularly asthma, are complex diseases with strong gene-environment interactions. Epidemiological studies have identified a variety of risk factors for the development of allergic diseases. Among them, endocrine-disrupting chemicals (EDCs) play an important role in triggering or exacerbating these diseases. 4-Nonylphenol (NP) and 4-octylphenol (OP)--two major alkylphenols--have been recognized as common toxic and xenobiotic endocrine disrupters. Due to their low solubility, high hydrophobicity, and low estrogenic activity, they tend to accumulate in the human body and may be associated with the adverse effects of allergic diseases.

Cancer is rapidly overtaking heart disease as the number one killer disease in developed countries, and this phenomenon is coupled with a growing aging population and concomitant age-related diseases. Therefore, it is not surprising that consumers are turning toward foods with medicinal properties as promising dietary interventions for disease prevention and health maintenance. Among fruits, berries of all colors have emerged as champions with substantial research data supporting their abilities to positively affect multiple disease states. Apart from several essential dietary components found in berries, such as vitamins, minerals, and fiber, berries also contain numerous bioactives that provide health benefits that extend beyond basic nutrition. Berry bioactives encompass a wide diversity of phytochemicals (phytonutrients) ranging from fat-soluble/lipophilic to water-soluble/hydrophilic compounds.

It is of unknown aetiology, but evidence suggests that it results from a combination of genetic predisposition and environmental factors. Bacterial-sized microparticles (0.1-1.0 microm) are potent adjuvants in model antigen-mediated immune responses and are increasingly associated with disease. Microparticles of TiO2 and aluminosilicate accumulate in macrophages of human gut-associated lymphoid tissue where the earliest signs of lesions in Crohn's disease are observed. Dietary microparticles are of endogenous or exogenous origin. Endogenous microparticles dominate and are calcium phosphate (most probably hydroxyapatite), which precipitates in the lumen of the mid-distal gastrointestinal tract due to secretion of Ca and phosphate in the succus entericus. Exogenous dietary microparticles are contaminants (soil and/or dust) and food additives. TiO2, for example, is a food colourant, and aluminosilicates are anti-caking agents, although some aluminosilicates occur as natural contaminants. Food additives alone account for ingestion of approximately 10(12) particles/person per d. Possible mechanisms for the role of exogenous and endogenous dietary microparticles in promoting toleragenic or immune responses of gastrointestinal mucosal phagocytosis are discussed. In a double-blind randomised pilot study we have shown that a diet low in Ca and exogenous microparticles appears to alleviate the symptoms of ileal Crohn's disease, with a significant (P= 0.002) improvement in the Crohn's disease activity index.

Recent findings Recent findings suggest that restriction of maternal diet during pregnancy and lactation does not play a major role in the development of allergic disease. In high risk infants exclusive breastfeeding for at least 4 months prevents or delays atopic dermatitis, cow milk allergy, and wheezing early in life. There is evidence that supplementing breastfeeding with a hydrolyzed formula protects against atopic disease, especially atopic dermatitis in at risk infants. Finally there is little evidence that delaying the introduction of complimentary foods beyond 4 to 6 months of age has any protective effect against allergy. There is insufficient data that any dietary intervention beyond 4 to 6 months of age has any protective effect against developing atopic disease. Summary In high risk infants there is evidence for exclusive breastfeeding for at least 4 months and delaying of complimentary foods until 4 to 6 months prevents the development of allergy.

You may have (slightly) more leverage in that case, but co-signing any loans is not a good idea, even for a friend or relative. As this article notes: Generally, co-signing refers to financing, not ownership. If the primary accountholder fails to make payments on the loan or the retail installment sales contract (a type of auto financing dealers sell), the co-signer is responsible for those payments, or their credit will suffer. Even if the co-signer makes the payments, they’re still not the owner if their name isn’t on the title. The Consumer Finance Protection Bureau (CFPB) notes: If you co-sign a loan, you are legally obligated to repay the loan in full. Co-signing a loan does not mean serving as a character reference for someone else. When you co-sign, you promise to pay the loan yourself. It means that you risk having to repay any missed payments immediately. If the borrower defaults on the loan, the creditor can use the same collection methods against you that can be used against the borrower such as demanding that you repay the entire loan yourself, suing you, and garnishing your wages or bank accounts after a judgment. Your credit score(s) may be impacted by any late payments or defaults. Co-signing an auto loan does not mean you have any right to the vehicle, it just means that you have agreed to become obligated to repay the amount of the loan. So make sure you can afford to pay this debt if the borrower cannot. Per this article and this loan.com article, options to remove your name from co-signing include: If you're name isn't on the title, you'll have to convince your ex-boyfriend and the bank to have you removed as the co-signer, but from your brief description above, it doesn't seem that your ex is going to be cooperative. Unfortunately, as the co-signer and guarantor of the loan, you're legally responsible for making the payments if he doesn't. Not making the payments could ruin your credit as well. One final option to consider is bankruptcy. Bankruptcy is a drastic option, and you'll have to weigh whether the disruption to your credit and financial life will be worth it versus repaying the balance of that auto loan. Per this post: Another not so pretty option is bankruptcy. This is an extreme route, and in some instances may not even guarantee a name-removal from the loan.

Actually funny enough I live in the wine region of CA and there is a whole business here of wine \"\"storage and shipping\"\" places. It's up to the states to decide how or if they allow alcohol to be shipped into their state from others, and a bunch of state have very complex rules or just don't allow it. So if you come out here for tourism, drink some wine at a winery, like it, and ask if you can have some shipped home, the answer is about 50/50 to be 'no'. And if you're a average income pleb, that's your answer. If you're some rich dude however, you can say \"\"ah gotcha, pesky laws... well here's the address of my storage and shipping place, send the 2 cases there then\"\", nobody bats an eye, and off the cases go. Guy goes home, calls up the shipping place, and says \"\"hey pull those cases, my personal property, and ship them to me\"\" and, somehow, magically, this is now legal.

But, wine is a high-end commodity, rich people make their own rules, and if CA turns a blind eye to this practice they get to collect the sales tax as it's sold in CA and shipped to a location in CA, whereas fighting it would hurt their tourism and also send the tax income to the states being shipped to. C.R.E.A.M. baby! Re-reading this now I'm not even sure if there IS a liability here. They bought the property in CA, paid tax in CA, and had it sent to a mailing address in CA. What they do after that with their personal property is not the states business, right? I'd imagine this would be drastically different if shipping for resale. Similarly, I think this all only works if you complete the transaction while physically in the state. So at most this might turn on some weed tourism.

That only pertains to customers who finance, the dealer is protected there because on isolated occasions, which the dealer hates as much as the customer, trust me, you are approved on contingency that the financing bank will approve your loan. That is an educated guess the finance manager makes based on credit history and past experience with the bank, which he is usually correct on. However there are times, especially late afternoon on Fridays when banks are preparing to close for the weekend the loan officer may not be able to approve you before closing time, in which case the dealer allows you to take the vehicle home until business is back up and running the following Monday. He does this mostly to give you sense of ownership, so you don't go down the street to the next dealership and go home in one of their vehicles. However, there are those few instances for whatever reason the bank decides your credit just isn't strong enough for the rate agreed upon, so the dealer will try everything he can to either change to a different lender, or sell the loan at a higher rate which he has to get you to agree upon.

In the extracellular region, the variable regions of PmDscam were located in N-terminal Ig2, N-terminal Ig3 and the entire Ig7 domain. The PmDscam extracellular variants and transmembrane domain variants were produced by mutually exclusive alternative splicing events. The cytoplasmic tail variants were produced by exon inclusion/exclusion.

By microarray and real-time PCR analyses, the allergen 1 gene (ALL1) was found to be downregulated in the hypervirulent mucoid switch variant, both during logarithmic growth and during intracellular growth in macrophages. The ALL1 gene encodes a small cytoplasmic protein that is involved in capsule formation. Growth of an all1Delta gene deletion mutant was normal. Similar to cells of the mucoid switch variant, all1Delta cells produced a larger polysaccharide capsule than cells of the smooth parent and the complemented strain produced, and the enlarged capsule inhibited macrophage phagocytosis. The mutant exhibited a modest defect in capsule induction compared to all of the other variants. In animal models the phenotype of the all1Delta mutant mimicked the hypervirulent phenotype of the mucoid switch variant, which is characterized by decreased host survival and elevated intracranial pressure. Decreased survival is likely the result of both an ineffective cell-mediated immune response and impaired phagocytosis by macrophages. Consequently, we concluded that, unlike loss of most virulence-associated genes, where loss of gene function results in attenuated virulence, loss of the ALL1 gene enhances virulence by altering the host-pathogen interaction and thereby impairing clearance.

METHODS We performed whole-exome sequencing in a patient with ataxia and hypogonadotropic hypogonadism, followed by targeted sequencing of candidate genes in similarly affected patients. Neurologic and reproductive endocrine phenotypes were characterized in detail. The effects of sequence variants and the presence of an epistatic interaction were tested in a zebrafish model. RESULTS Digenic homozygous mutations in RNF216 and OTUD4, which encode a ubiquitin E3 ligase and a deubiquitinase, respectively, were found in three affected siblings in a consanguineous family. Additional screening identified compound heterozygous truncating mutations in RNF216 in an unrelated patient and single heterozygous deleterious mutations in four other patients. Knockdown of rnf216 or otud4 in zebrafish embryos induced defects in the eye, optic tectum, and cerebellum; combinatorial suppression of both genes exacerbated these phenotypes, which were rescued by nonmutant, but not mutant, human RNF216 or OTUD4 messenger RNA.

We reported previously that both EGFR- and Her2-overexpressing tumors are sensitive to the new EGFR-selective TK inhibitor gefitinib (ZD1839, \"Iressa\"), and sensitivity to this agent correlated with its ability to down-regulate Akt. However, EGFR-overexpressing MDA-468 cells, which lack PTEN function, are resistant to ZD1839, and ZD1839 is unable to down-regulate Akt activity in these cells. EXPERIMENTAL DESIGN To study the role of PTEN function, we generated MDA468 cells with tet-inducible PTEN expression. RESULTS We show here that the resistance of MDA-468 cells to ZD1839 is attributable to EGFR-independent constitutive Akt activation caused by loss of PTEN function in these cells. Reconstitution of PTEN function through tet-inducible expression restores ZD1839 sensitivity to these cells and reestablishes EGFR-stimulated Akt signaling. Although restoration of PTEN function to tumors is difficult to implement clinically, much of the effects of PTEN loss are attributable to overactive PI3K/Akt pathway signaling, and this overactivity can be modulated by pharmacologic approaches. We show here that pharmacologic down-regulation of constitutive PI3K/Akt pathway signaling using the PI3K inhibitor LY294002 similarly restores EGFR-stimulated Akt signaling and sensitizes MDA-468 cells to ZD1839. CONCLUSIONS Sensitivity to ZD1839 requires intact growth factor receptor-stimulated Akt signaling activity.

In this study, a genetic screen identified a second-site mutation hen1 suppressor1-2 (heso1-2) that partially suppresses the morphological phenotypes of the hypomorphic hen1-2 allele and the null hen1-1 allele in Arabidopsis. HESO1 encodes a terminal nucleotidyl transferase that prefers to add untemplated uridine to the 3' end of RNA, which is completely abolished by 2'-O-methylation. heso1-2 affects the profile of u-tailed miRNAs and siRNAs and increases the abundance of truncated and/or normal sized ones in hen1, which often results in increased total amount of miRNAs and siRNAs in hen1. In contrast, overexpressing HESO1 in hen1-2 causes more severe morphological defects and less accumulation of miRNAs. These results demonstrate that HESO1 is an enzyme uridylating unmethylated miRNAs and siRNAs in hen1.

H3K36 trimethylation (H3K36me3) is deposited onto the nucleosomes in the transcribed regions after RNA polymerase II elongation. In yeast, this mark in turn recruits epigenetic regulators to reset the chromatin to a relatively repressive state, thus suppressing cryptic transcription. However, much less is known about the role of H3K36me3 in transcription regulation in mammals. This is further complicated by the transcription-coupled incorporation of the histone variant H3.3 in gene bodies. Here we show that the candidate tumour suppressor ZMYND11 specifically recognizes H3K36me3 on H3.3 (H3.3K36me3) and regulates RNA polymerase II elongation. Structural studies show that in addition to the trimethyl-lysine binding by an aromatic cage within the PWWP domain, the H3.3-dependent recognition is mediated by the encapsulation of the H3.3-specific ‘Ser 31’ residue in a composite pocket formed by the tandem bromo–PWWP domains of ZMYND11. Chromatin immunoprecipitation followed by sequencing shows a genome-wide co-localization of ZMYND11 with H3K36me3 and H3.3 in gene bodies, and its occupancy requires the pre-deposition of H3.3K36me3. Although ZMYND11 is associated with highly expressed genes, it functions as an unconventional transcription co-repressor by modulating RNA polymerase II at the elongation stage. ZMYND11 is critical for the repression of a transcriptional program that is essential for tumour cell growth; low expression levels of ZMYND11 in breast cancer patients correlate with worse prognosis. Consistently, overexpression of ZMYND11 suppresses cancer cell growth in vitro and tumour formation in mice. Together, this study identifies ZMYND11 as an H3.3-specific reader of H3K36me3 that links the histone-variant-mediated transcription elongation control to tumour suppression.", "title": "ZMYND11 links histone H3.3K36me3 to transcription elongation and tumour suppression" }, { "docid": "519974", "text": "Mammals detect temperature with specialized neurons in the peripheral nervous system.

Jack doesn't compensate himself for the equity sale, as he didn't sell anything. The company traded shares for money which it uses for expansion. In the long term, the capital gain from expansion may exceed the value of a $200,000 no-interest loan to the company. If the value of the company before investing $250,000 is $1 million, then the value after investing is $1.25 million. So $250,000 is 20% of the value of the company.

With the other example, Jack sells 25% of the company for $250,000 from his personal shares. This doesn't change the assessed value of the company, just Jack's stake.

[ { "docid": "115814", "text": "Does it make sense for stocks to earn a premium indefinitely? Yes. There is good reason to think that the stock market will make money indefinitely: the stock market is the primary mechanism through which investors bear market risk, which requires compensation. If you think of all the owners of firms (stockholders and bondholders, generally) the risk premium that stocks earn stocks is the way bondholders pay equityholders to bear the risk that they do not wish to. Will stock prices always go up in the long run? As long as companies pay out less in dividends than their profit, prices will go up. That could change if we were to change our corporate culture and/or tax practices so that firms paid out more in dividends. However, for the purposes of your question, I think it doesn't matter much whether the investor makes money as dividends or capital gains. Does the 5-7% guess apply only to the US market? I didn't write (nor read) the books in question, but most likely that is a global number. The US dominates the global equity market, so it's often a good proxy. However, international returns taken together have no less risk and earn no less over long horizons in general. The particular examples you have pointed out are special cases that only apply to a part of the global economy and a particular time period. There are plenty of examples of stock markets and time periods that did much better than the US market to offset your examples. Is 5-7% a reasonable long-term estimate of equity returns? Equity will always earn more in expectation than risk-free securities will. How much more depends on major economic factors. 5-7% has been a good estimate for the market risk premium for many, many decades (stocks should earn this plus whatever the risk-free rate is). However, that is just an empirical observation, not a rule. It can change. Some day technological progress could slow down or stop, we could run out of important resources in a way that we can't compensate for, our population permanently could stop growing, aliens could invade, etc. Down the road it is certainly possible for expected equity returns to go down and never go back up again.

In theory, the value of a share price does not directly impact the operation of the company itself, apart from what @DanielCarson aptly noted (employee stock options are affected by share price, impacting morale, etc.). This is because in theory, the true value of a company (and thus, the value of a share) is the present value of all future cashflows (dividends + final liquidation). This means that in a technical sense, a company's share price should result from the company's value. The company's true value does not result from the share price. But what you are doing as a shareholder is impacting the liquidity available to other potential investors (also as mentioned by @DanielCarson, in reference to the desirability for future financing). The more people who invest their money in the stock market, the more liquid those stocks become.

If your money doesn't grow in an investment vehicle, it's ultimately a shit investment. But no one values intrinsic value of a company's equity before they decide whether or not $380 for TSLA is a good/bad deal.

People can make shitloads of money on stock without an equitable loser--people can also lose shitloads on stock without any real winner emerging from the rubble. When this bubble bursts, lots and lots of people will lose money on TSLA when people's expectations become rational and they stop paying $300 a share for a negative or 70 PE ratio. It's insane what multipliers people will pay for these companies without even realizing the implication--if you buy a share of a company with a PE ratio of 70, you just paid 70 times their earnings for a share. In an ideal world where they released every single penny of earnings as dividends, it would take you 70 periods to reclaim your money on that share.

Imagine a market where everyone just agreed to pump up a single stock to infinity and everyone just rakes in shitloads of money. Would this work? Of course not. It's literally a pyramid scheme that relies on future generations to constantly inject capital--no real value is being created by this scheme. It requires constantly more future generations to continue adding money into the scheme and will crash once people stop pumping money into it. The same thing will happen here. Everyone \"\"agreed\"\" to pump up TSLA (in a sense) but eventually people will realize this is stupid as shit and the pyramid will come tumbling down because there is nothing they receive from this scheme other than the money from other people. It's essentially moving money around, making 0 use of it, until people stop pumping money into the system and everyone realizes that nothing of real value had been produced through the use of this money. Ultimately the only thing that creates real value is the money that is returned to shareholders from an outside party--the company you're invested in. Real value is not created when people exchange stock and money. So why do these transactions create higher values in equity? The basis of equity valuation states that dividends are the only way for companies to raise the price of their stock, going off the traditional Dividend Discount Model. And theoretically, that's the only logical explanation. Buying and trading stock does nothing for the company, minus T Stock they might own. Ultimately the only party creating real value is the underlying company. If they aren't creating real value, then their stock should not be increasing, period. The way they create value is by efficiently utilizing assets to generate returns on investment which can be returned to investors through dividends. Dividends can only be increased (while maintaining an equitable payout ratio) by generating more net income that can increase the actual pool of money that can be allocated back to investors. TSLA does not do this. TSLA regularly loses money and overpromises. There is no logical explanation for any of this except that everyone is irrational. Obviously theory is not the same as in practice but the theory is important here because it's really the basis for any investment at all. At the end of the day, a share of stock is the right to a share of the company's equity. People own equity in companies because companies generate money that it returns back to its owners. That's what a company does. That's what an owner does. If you own shares of a company, you're an owner. And if your company does not return more money back to you YoY, then why are you invested in them?

The corporation itself owns all of those assets, but the board controls them. In this example, they scheme with most likely the top executive, but a rubber stamp top executive could allow a lower rung to scheme with the board, but the board is always constant until the law is changed. Because there's no honor amongst thieves, the board votes which can require some combination of executive and shareholder approval are taken very close together: sell shares, increase salaries to key executive schemers, increase board compensation.

Bonds are offered to the public - ie: you could potentially buy a \"\"Tesla Bond\"\", where you give Tesla $1k, and they give you a stated interest rate over time, and principal repayments according to a schedule. Which type of debt a corporation uses will depend mostly on the high cost of offering a public bond, the relationships with current banks, and the interest rates the corporation thinks it can get from either method. Equity [or, shares] is money that the corporation (to put it simply) likely does not have a legal obligation to repay, until the corporation is liquidated (sold at the end of its life) and all debt has already been repaid. But when the corporation is liquidated, the shareholders have a legal right to the entire value of the company, after those debts have been paid. So equity holders have higher risk than debt holders, but they also can share in higher reward. That is why stock prices are so volatile - the value of each share fluctuates based on the perceived value of the entire company. Some equity may be offered with specific rules about dividend payments - maybe they are required [a 'preferred' share likely has a stated dividend rate almost like a bond, but also likely has a limited value it can ever receive back from the corporation], maybe they are at the discretion of the board of directors, maybe they will never happen. There are 2 broad ways for a corporation to get money from equity: a private offering, or a public offering. A private offering could be a small mom and pop store asking their neighbors to invest 5k so they can repair their business's roof, or it could be an 'Angel Investor' [think Shark Tank] contributing significant value and maybe even taking control of the company. Perhaps shares would be offered to all current shareholders first. A public offering would be one where shares would be offered up to the public on the stock exchange, so that anyone could subscribe to them. Why a corporation would use any of these different methods depends on the price it feels it could get from them, and also perhaps whether there are benefits to having different shareholders involved in the business [ie: an Angel investor would likely be involved in the business to protect his/her investment, and that leadership may be what the corporation actually needs, as much or more than money]. Whether a corporation chooses to gain cash from earnings, debt, or equity depends on many factors, including but not limited to: (1) what assets / earnings potential it currently has; (2) the cost of acquiring the cash [ie: the high cost of undergoing a public offering vs the lower cost of increasing a bank loan]; and (3) the ongoing costs of that cash to both the corporation and ultimately the other shareholders - ie: a 3% interest rate on debt vs a 6% dividend rate on preferred shares vs a 5% dividend rate on common shares [which would also share in the net value of the company with the other current shareholders]. In summary: Earnings would be generally preferred, but if the company needs cash immediately, that may not be suitable. Debt is generally cheap to acquire and interest rates are generally lower than required dividend rates. Equity is often expensive to acquire and maintain [either through dividend payments or by reduction of net value attributable to other current shareholders], but may be required if a new venture is risky. ie: a bank/bondholder may not want to lend money for a new tech idea because it is too risky to just get interest from - they want access to the potential earnings as well, through equity.\"", "title": "" }, { "docid": "108770", "text": "\"A bit strange but okay. The way I would think about this is again that you need to determine for what purpose you're computing this, in much the same way you would if you were to build out the model. The IPO valuation is not going to be relevant to the accretion/dilution analysis unless you're trying to determine whether the transaction was net accretive at exit. But that's a weird analysis to do. For longer holding periods like that you're more likely to look at IRR, not EPS. EPS is something investors look at over the short to medium term to get a sense of whether the company is making good acquisition decisions. And to do that short-to-medium term analysis, they look at earnings. Damodaran would say this is a shitty way of looking at things and that you should probably be looking at some measure of ROIC instead, and I tend to agree, but I don't get paid to think like an investor, I get paid to sell shit to them (if only in indirect fashion). The short answer to your question is that no, you should not incorporate what you are calling liquidation value when determining accretion/dilution, but only because the market typically computes accretion/dilution on a 3-year basis tops. I've never put together a book or seen a press release in my admittedly short time in finance that says \"\"the transaction is estimated to be X% accretive within 4 years\"\" - that just seems like an absurd timeline. Final point is just that from an accounting perspective, a gain on a sale of an asset is not going to get booked in either EBITDA or OCF, so just mechanically there's no way for the IPO value to flow into your accretion/dilution analysis there, even if you are looking at EBITDA/shares. You could figure the gain on sale into some kind of adjusted EBITDA/shares version of EPS, but this is neither something I've ever seen nor something that really makes sense in the context of using EPS as a standardized metric across the market. Typically we take OUT non-recurring shit in EPS, we don't add it in. Adding something like this in would be much more appropriate to measuring the success of an acquisition/investing vehicle like a private equity fund, not a standalone operating company that reports operational earnings in addition to cash flow from investing. And as I suggest above, that's an analysis for which the IRR metric is more ideally situated. And just a semantic thing - we typically wouldn't call the exit value a \"\"liquidation value\"\". That term is usually reserved for dissolution of a corporate entity and selling off its physical or intangible assets in piecemeal fashion (i.e. not accounting for operational synergies across the business). IPO value is actually just going to be a measure of market value of equity.\"", "title": "" }, { "docid": "79411", "text": "\"This is not an end-all answer but it'll get you started I have been through accounting courses in college as well as worked as a contractor (files as sole proprietor) for a few years but IANAA (I am not an accountant). Following @MasonWheeler's answer, if you're making that much money you should hire a bean counter to at least overlook your bookkeeping. What type of business? First, if you're the sole owner of the business you will most likely file as a sole proprietorship. If you don't have an official business entity, you should get it registered officially asap, and file under that name. The problem with sole proprietorships is liability. If you get sued, not only are your business' assets vulnerable but they can go after your personal assets too (including house/cars/etc). Legally, you and your business are considered one and the same. To avoid liability issues, you could setup a S corporation. Basically, the business is considered it's own entity and legal matters can only take as much as the business owns. You gain more protection but if you don't explicitly keep your business finances separate from your personal finances, you can get into a lot of trouble. Also, corporations generally pay out more in taxes. Technically, since the business is it's own entity you'll need to pay yourself a 'reasonable salary'. If you skip the salary and pay yourself the profits directly (ie evade being taxed on income/salary) the IRS will shut you down (that's one of the leading causes of corporations being shut down). You can also pay distribute bonuses on top of that but it would be wise to burn the words 'within reason' into your memory first. The tax man gets mad if you short him on payroll taxes. S corporations are complicated, if you go that route definitely seek help from an accountant. Bookkeeping If you're not willing to pay a full time accountant you'll need to do a lot of studying about how this works. Generally, even if you have a sole proprietorship it's best to have a separate bank account for all of your business transactions. Every source/drain of money will fall into one of 3 categories... Assets - What your business owns: Assets can be categorized by liquidity. Meaning how fast you can transform them directly into cash. Just because a company is worth a lot doesn't necessarily mean it has a lot of cash. Some assets depreciate (lose value over time) whereas some are very hard to transform back into cash based on the value and/or market fluctuations (like property). Liabilities - What you owe others and what others owe you: Everything you owe and everything that is owed to you gets tracked. Just like credit cards, it's completely possible to owe more than you own as long as you can pay the interest to maintain the loans. Equity - the net worth of the company: The approach they commonly teach in schools is called double-entry bookkeeping where they use the equation: In practice I prefer the following because it makes more sense: Basically, if you account for everything correctly both sides of the equation should match up. If you choose to go the sole proprietorship route, it's smart to track everything I've mentioned above but you can choose to keep things simple by just looking at your Equity. Equity, the heart of your business... Basically, every transaction you make having to do with your business can be simplified down to debits (money/value) increasing and credits (money/value) decreasing. For a very simple company you can assess this by looking at net profits. Which can be calculated with: Revenues, are made up of money earned by services performed and goods sold. Expenses are made up of operating costs, materials, payroll, consumables, interest on liabilities, etc. Basically, if you brought in 250K but it cost you 100K to make that happen, you've made 150K for the year in profit. So, for your taxes you can count up all the money you've made (Revenues), subtract all of the money you've paid out (Expenses) and you'll know how much profit you've made. The profit is what you pay taxes on. The kicker is, there are gray areas when it comes to deducting expenses. For instance, you can deduct the expense of using your car for business but you need to keep a log and can only expense the miles you traveled explicitly for business. Same goes for deducting dedicated workspaces in your house. Basically, do the research if you're not 100% sure about a deduction. If you don't keep detailed books and try to expense stuff without proof, you can get in trouble if the IRS comes knocking. There are always mythical stories about 'that one guy' who wrote off his boat on his taxes but in reality, you can go to jail for tax fraud if you do that. It comes down to this. At the end of the year, if your business took in a ton of money you'll owe a lot in taxes. The better you can justify your expenses, the more you can reduce that debt. One last thing. You'll also have to pay your personal federal/state taxes (including self-employment tax). That means medicare/social security, etc. If this is your first foray into self-employment you're probably not familiar with the fact that 1099 employers pick up 1/2 of the 15% medicare/social security bill. Typically, if you have an idea of what you make annually, you should be paying this out throughout the year. My pay as a contractor was always erratic so I usually paid it out once/twice a year. It's better to pay too much than too little because the gov't will give you back the money you overpaid. At the end of the day, paying taxed sucks more if you're self-employed but it balances out because you can make a lot more money. If as you said, you've broken six figures, hire a damn accountant/adviser to help you out and start reading. When people say, \"\"a business degree will help you advance in any field,\"\" it's subjects like accounting are core requirements to become a business undergrad.

If you always paid the mortgage out of the joint account, you could presumably go back and look at the account to find out how much each of you contributed to it.

Let's simplify it a little bit. Paying down your mortgage makes sense if your expected return in the rest of your portfolio is less than the cost of the mortgage. In many cases, people may also decide to pay down their mortgage because they are risk-averse and do not like carrying debt. There's no tax benefit to doing so, though; Canada doesn't generally allow you to write off mortgage interest, unlike the U.S. As to keeping money in the corporation or not, I'm not going to address that. I don't have a firm enough understanding of corporate taxation. Canadian Couch Potato advises treating all of your investment assets as one large portfolio. That is what you are trying to do here. However, let's consider a different approach. If you do not have enough money to max out your RRSP or TFSA, you may choose to keep your TFSA for an emergency fund, where the money is kept highly liquid. Keep your cash in an interest-bearing TFSA, or perhaps invest it in the money market, inside your TFSA. Then, use your RRSP for the rest of your investment money, split according to your investment goals. This is not the most tax-efficient approach, but it is nice and simple. But you are looking for the most tax-efficient approach. So, let's assume you have enough to more than max out your TFSA and RRSP contributions, and all of your investments are going toward your retirement, which is at least a decade away. Because you are not taxed on your investment income from RRSPs (until you withdraw the money) or TFSA, it makes sense to hold the least tax-efficient investments there. Tax-advantaged investments such as Canadian equities should be held in your investment accounts outside of TFSA and RRSPs. Again, the Canadian Couch Potato has a great article on where to put your investment assets. That article covers interest, dividends, foreign dividends, and capital gains, as well as RRSPs, RESPs, and TFSAs. That article recommends holding Canadian equities in a taxable account, REITs in a tax-sheltered account (TFSA or RRSP), bonds, GICs, and money-market funds in a tax-sheltered account (as these count as interest). The article goes into rather more detail than this, and is worth checking out. It mentions the 15% withholding tax on US-listed ETFs, for example.

With that said, you want to look at a few to several years of books, look for trends. Some things to understand that might be subtle red flags: It's extremely common for early stage investors to essentially make loans rather than strictly buying shares. In the worst case scenario creditors get to participate in liquidation proceedings before shareholders do. You may be better off investing in this business via a loan that's convertible to equity at your discretion. Single owner service companies are difficult because all of the net earnings go to the proprietor and that person maintains all of the relationships. So taking something like 5 years of net earnings as the value of the company doesn't make much sense because you (or someone else) couldn't just step in and replace the owner. Granted, you aren't contemplating taking over the business, but it negates using an X years of net earnings valuation method. When you read about valuation there is a sort of overriding assumption that no single person could topple the operation which couldn't be farther from the truth in single employee service companies.

Getting rid of the HELOC and converting to a fixed mortgage would be my first priority.

Some are able to make it work. Some of those go broke or lose their properties. when calculating the 20% down of a new property, does that need to be liquid funds, or can that be based on the value of the home you are selling You can make the purchase of the new home contingent on the sale of the first if you need to get the equity out of it to make the 20%.

However, instead of buying shares, they simply quit after being paid the salary. They use knowledge gained from this business to start a competitor. Investors are left holding an empty company.

By contrast, if the founder instead sells shares, that would be capital gains tax, which is lower in many countries (e.g. the United States).

A single employee company instead looks for private investors, often called angel investors. Companies generally don't go public until they are established in some way, often making money. Negotiating with angel investors is different from negotiating with the public. They can personally review the books and once invested tend to have input on how the money is spent. In other words, this is mostly solving the wrong problem if you talk about IPOs. This might make more sense with a crowdfunded venture, as that replaces a few angel investors with many individuals.

You can cosign for this person, say for a car loan to get them a car they can drive to that job, knowing that they aren't going to walk away and just stop making the payments. The loan issuer doesn't know any of that. Or consider a young person with poor credit but good income who has recently decided to get smart about money, has written out a budget and a plan to rehabilitate their credit, and who you know will work passionately to make every payment and get the credit score up to a place where they can buy a house or whatever their goal is.

If you charge 600 € / month (and never miss a month of rental income), after 21 years you have made 151k € in rents plus you still have a property. That property is most likely going to be worth more than you paid for it, so you should have at least 300k € in assets.

I think an underrated cost of investing is the tax penalties that you pay when you win if you aren't using a tax advantaged account. For your speculating account, you might want to open a self-directed IRA so that you can get access to more of the high risk options that you crave without the tax liability if any of those have a big payout. You want your high-growth money to be in a Roth, because it would be a shame to strike it rich while you're young and then have to pay taxes on it when you're older. If you choose not to make these investments in a tax-advantaged account, try to hold your stocks for a year so you only get taxed at capital gains rates instead of as ordinary income. If you choose to work for a startup, buy your stock options as they vest so that if the company goes public or sells privately, you will have owned those stocks long enough to qualify for capital gains. If you want my actual advice about what I think you should do: I would increase your 401k percentage to at least 10% with or without a match, and keep that in low cost index funds while you're young, but moving some of those investments over to bonds as you get closer to retirement and your risk tolerance declines. Assuming you're not in the 25% tax bracket, all of your money should be in a Roth 401k or IRA because you can withdraw it without being taxed when you retire. The more money you put into those accounts now while you are young, the more time it all has to grow.

My main question is with how far away it is (over 1000 miles), how do I quantify the travel expenses? Generally, \"\"necessary and ordinary\"\" expenses are deductible. This is true for business and also true for rentals. But what is necessary and what is ordinary? Is it ordinary that a landlord will manage the property 1000 miles away by himself on a daily basis? Is it ordinary for people to drive 1000 miles every week? I'd say \"\"no\"\" to both. I'd say it would be cheaper for you to hire a local property manager, thus the travel expense would not be necessary. I would say it would be cheaper to fly (although I don't know if its true to the specific situation of the OP, but as I said - its too localized to deal with) rather than drive from Texas to Colorado. If the OP thinks that driving a thousand miles is indeed ordinary and necessary he'll have to justify it to the IRS examiner, as I'm sure it will be examined. 2 trips to the property a year will be a nearly 100% write-off (2000 miles, hotels, etc). From what I understood (and that is what I've been told by my CPA), IRS generally allows 1 (one) trip per year per property. If there's an exceptional situation - be prepared to justify it. Also, keep all the receipts (like gas, hotel, etc.... If you claim mileage but in reality you took a flight - you'll get hit hard by the IRS when audited). Also while I'm up there am I allowed to mix business with pleasure? You cannot deduct personal (\"\"pleasure\"\") expenses, at all. If the trip is mainly business, but you go out at the evening instead of staying at the hotel - that's fine. But if the trip is \"\"business\"\" trip where you spend a couple of hours at your property and then go around having fun for two days - the whole trip may be disallowed. If there's a reasonable portion dedicated to your business/rental, and the rest is pleasure - you'll have to split some of the costs and only deduct the portion attributed to the business activities. You'll have to analyze your specific situation, and see where it falls. Don't stretch the limits too much, it will cost you more on the long run after all the audits and penalties. Can I also write off all travel involved in the purchase of the property? Although, again, the \"\"necessary and ordinary\"\" justification of such a trip is arguable, lets assume it is necessary and ordinary and generally justified. It is reasonable to expect you to go and see the property with your own eyes before the closing (IMHO, of course, I'm not an authority). Such an expense can be either business or investment expense. If its a business expense - its deductible on schedule C. If its an investment expense (if you do buy the property), its added to the cost of the property (capitalized).

For others, there are higher priorities. What it should be for you depends on a number of things, including your overall financial situation (both your current finances and how stable you expect them to be over time), your level of financial \"\"education\"\", the costs of your mortgage, the alternative investments available to you, your investing goals, and your tolerance for risk. Your #1 priority should be to ensure that your basic needs (including making the required monthly payment on your mortgage) are met, both now and in the near future, which includes paying off high-interest (i.e. credit card) debt and building up an emergency fund in a savings or money-market account or some other low-risk and liquid account. If you haven't done those things, do not pass Go, do not collect $200, and do not consider making advance payments on your mortgage. Mason Wheeler's statements that the bank can't take your house if you've paid it off are correct, but it's going to be a long time till you get there and they can take it if you're partway to paying it off early and then something bad happens to you and you start missing payments. (If you're not underwater, you should be able to get some of your money back by selling - possibly at a loss - before it gets to the point of foreclosure, but you'll still have to move, which can be costly and unappealing.) So make sure you've got what you need to handle your basic needs even if you hit a rough patch, and make sure you're not financing the paying off of your house by taking a loan from Visa at 27% annually. Once you've gotten through all of those more-important things, you finally get to decide what else to invest your extra money in. Different investments will provide different rewards, both financial and emotional (and Mason Wheeler has clearly demonstrated that he gets a strong emotional payoff from not having a mortgage, which may or may not be how you feel about it). On the financial side of any potential investment, you'll want to consider things like the expected rate of return, the risk it carries (both on its own and whether it balances out or unbalances the overall risk profile of all your investments in total), its expected costs (including its - and your - tax rate and any preferred tax treatment), and any other potential factors (such as an employer match on 401(k) contributions, which are basically free money to you). Then you weigh the pros and cons (financial and emotional) of each option against your imperfect forecast of what the future holds, take your best guess, and then keep adjusting as you go through life and things change. But I want to come back to one of the factors I mentioned in the first paragraph. Which options you should even be considering is in part influenced by the degree to which you understand your finances and the wide variety of options available to you as well as all the subtleties of how different things can make them more or less advantageous than one another. The fact that you're posting this question here indicates that you're still early in the process of learning those things, and although it's great that you're educating yourself on them (and keep doing it!), it means that you're probably not ready to worry about some of the things other posters have talked about, such as Cost of Capital and ROI. So keep reading blog posts and articles online (there's no shortage of them), and keep developing your understanding of the options available to you and their pros and cons, and wait to tackle the full suite of investment options till you fully understand them. However, there's still the question of what to do between now and then. Paying the mortgage down isn't an unreasonable thing for you to do for now, since it's a guaranteed rate of return that also provides some degree of emotional payoff. But I'd say the higher priority should be getting money into a tax-advantaged retirement account (a 401(k)/403(b)/IRA), because the tax-advantaged growth of those accounts makes their long-term return far greater than whatever you're paying on your mortgage, and they provide more benefit (tax-advantaged growth) the earlier you invest in them, so doing that now instead of paying off the house quicker is probably going to be better for you financially, even if it doesn't provide the emotional payoff. If your employer will match your contributions into that account, then it's a no-brainer, but it's probably still a better idea than the mortgage unless the emotional payoff is very very important to you or unless you're nearing retirement age (so the tax-free growth period is small). If you're not sure what to invest in, just choose something that's broad-market and low-cost (total-market index funds are a great choice), and you can diversify into other things as you gain more savvy as an investor; what matters more is that you start investing in something now, not exactly what it is.

First, yes, you should be diversified. The bulk of how a stock's movement will be in keeping with how its sector moves; so even a really great stock can get creamed if its sector is going down. Diversification between several sectors will help balance that. However, you will have some advantage in this sector. Knowing which products are good, which products everybody in the industry is excited about, is a huge advantage over other investors. It'll help you pick the ones that go up more when the sector goes up, and down less when the sector goes down. That, over time and investments, really adds up.

A great company can have a sky-high valuation -- and if you buy it at that price, you can sit there and watch your investment sink even as the company is growing and doing great things.

You can expect to pay 15%-20% more for landlord insurance than regular insurance (100$/month is not a bad number to just plug in when running numbers its probably high). Also your lease should require tenants to have renters insurance to help protect you. Have a liability conversation with a lawyer and think about LLCs. How is the house price increase going to act as another source of income? Appreciation can be another source of income but it is not really that useful in your scenario. It is not liquid you will not realize it until you sell the property and then you have to pay capital gains and depreciation recapture on it. There are methods to get access to the gains on the property without paying taxes.

We demonstrate here that metabolism by intestinal microbiota of dietary L-carnitine, a trimethylamine abundant in red meat, also produces TMAO and accelerates atherosclerosis in mice. Omnivorous human subjects produced more TMAO than did vegans or vegetarians following ingestion of L-carnitine through a microbiota-dependent mechanism. The presence of specific bacterial taxa in human feces was associated with both plasma TMAO concentration and dietary status. Plasma L-carnitine levels in subjects undergoing cardiac evaluation (n = 2,595) predicted increased risks for both prevalent cardiovascular disease (CVD) and incident major adverse cardiac events (myocardial infarction, stroke or death), but only among subjects with concurrently high TMAO levels. Chronic dietary L-carnitine supplementation in mice altered cecal microbial composition, markedly enhanced synthesis of TMA and TMAO, and increased atherosclerosis, but this did not occur if intestinal microbiota was concurrently suppressed. In mice with an intact intestinal microbiota, dietary supplementation with TMAO or either carnitine or choline reduced in vivo reverse cholesterol transport. Intestinal microbiota may thus contribute to the well-established link between high levels of red meat consumption and CVD risk.", "title": "Intestinal microbiota metabolism of L-carnitine, a nutrient in red meat, promotes atherosclerosis" } ]
[ { "docid": "6327940", "text": "Amino acids modulate the secretion of both insulin and glucagon; the composition of dietary protein therefore has the potential to influence the balance of glucagon and insulin activity. Soy protein, as well as many other vegan proteins, are higher in non-essential amino acids than most animal-derived food proteins, and as a result should preferentially favor glucagon production. Acting on hepatocytes, glucagon promotes (and insulin inhibits) cAMP-dependent mechanisms that down-regulate lipogenic enzymes and cholesterol synthesis, while up-regulating hepatic LDL receptors and production of the IGF-I antagonist IGFBP-1. The insulin-sensitizing properties of many vegan diets--high in fiber, low in saturated fat--should amplify these effects by down-regulating insulin secretion. Additionally, the relatively low essential amino acid content of some vegan diets may decrease hepatic IGF-I synthesis. Thus, diets featuring vegan proteins can be expected to lower elevated serum lipid levels, promote weight loss, and decrease circulating IGF-I activity. The latter effect should impede cancer induction (as is seen in animal studies with soy protein), lessen neutrophil-mediated inflammatory damage, and slow growth and maturation in children. In fact, vegans tend to have low serum lipids, lean physiques, shorter stature, later puberty, and decreased risk for certain prominent 'Western' cancers; a vegan diet has documented clinical efficacy in rheumatoid arthritis. Low-fat vegan diets may be especially protective in regard to cancers linked to insulin resistance--namely, breast and colon cancer--as well as prostate cancer; conversely, the high IGF-I activity associated with heavy ingestion of animal products may be largely responsible for the epidemic of 'Western' cancers in wealthy societies. Increased phytochemical intake is also likely to contribute to the reduction of cancer risk in vegans. Regression of coronary stenoses has been documented during low-fat vegan diets coupled with exercise training; such regimens also tend to markedly improve diabetic control and lower elevated blood pressure. Risk of many other degenerative disorders may be decreased in vegans, although reduced growth factor activity may be responsible for an increased risk of hemorrhagic stroke. By altering the glucagon/insulin balance, it is conceivable that supplemental intakes of key non-essential amino acids could enable omnivores to enjoy some of the health advantages of a vegan diet. An unnecessarily high intake of essential amino acids--either in the absolute sense or relative to total dietary protein--may prove to be as grave a risk factor for 'Western' degenerative diseases as is excessive fat intake.", "title": "Vegan proteins may reduce risk of cancer, obesity, and cardiovascular disease by promoting increased glucagon activity." }, { "docid": "33684572", "text": "Recent studies indicate both clinical and mechanistic links between atherosclerotic heart disease and intestinal microbial metabolism of certain dietary nutrients producing trimethylamine N-oxide (TMAO).

Mice receiving C57BL/6J cecal microbes demonstrated choline diet-dependent enhancement in atherosclerotic plaque burden as compared with recipients of NZW/LacJ microbes. Microbial DNA analyses in feces and cecum revealed transplantation of donor microbial community features into recipients with differences in taxa proportions between donor strains that were transmissible to recipients and that tended to show coincident proportions with TMAO levels.

PARTICIPANTS A total of 96,469 Seventh-day Adventist men and women recruited between 2002 and 2007, from which an analytic sample of 73,308 participants remained after exclusions. EXPOSURES Diet was assessed at baseline by a quantitative food frequency questionnaire and categorized into 5 dietary patterns: nonvegetarian, semi-vegetarian, pesco-vegetarian, lacto-ovo-vegetarian, and vegan. MAIN OUTCOME AND MEASURE The relationship between vegetarian dietary patterns and all-cause and cause-specific mortality; deaths through 2009 were identified from the National Death Index.

We developed a novel co-culture system to understand the mechanism(s) by which a loss of stromal fibroblast Cav-1 induces a \"lethal tumor micro-environment. \" Here, we propose a new paradigm to explain the powerful prognostic value of stromal Cav-1. In this model, cancer cells induce oxidative stress in cancer-associated fibroblasts, which then acts as a \"metabolic\" and \"mutagenic\" motor to drive tumor-stroma co-evolution, DNA damage and aneuploidy in cancer cells. More specifically, we show that an acute loss of Cav-1 expression leads to mitochondrial dysfunction, oxidative stress and aerobic glycolysis in cancer associated fibroblasts. Also, we propose that defective mitochondria are removed from cancer-associated fibroblasts by autophagy/mitophagy that is induced by oxidative stress. As a consequence, cancer associated fibroblasts provide nutrients (such as lactate) to stimulate mitochondrial biogenesis and oxidative metabolism in adjacent cancer cells (the \"Reverse Warburg Effect\"). We provide evidence that oxidative stress in cancer-associated fibroblasts is sufficient to induce genomic instability in adjacent cancer cells, via a bystander effect, potentially increasing their aggressive behavior. Finally, we directly demonstrate that nitric oxide (NO) over-production, secondary to Cav-1 loss, is the root cause for mitochondrial dysfunction in cancer associated fibroblasts. In support of this notion, treatment with anti-oxidants (such as N-acetyl-cysteine, metformin and quercetin) or NO inhibitors (L-NAME) was sufficient to reverse many of the cancer-associated fibroblast phenotypes that we describe. Thus, cancer cells use \"oxidative stress\" in adjacent fibroblasts (i) as an \"engine\" to fuel their own survival via the stromal production of nutrients and (ii) to drive their own mutagenic evolution towards a more aggressive phenotype, by promoting genomic instability. We also present evidence that the \"field effect\" in cancer biology could also be related to the stromal production of ROS and NO species. eNOS-expressing fibroblasts have the ability to downregulate Cav-1 and induce mitochondrial dysfunction in adjacent fibroblasts that do not express eNOS. As such, the effects of stromal oxidative stress can be laterally propagated, amplified and are effectively \"contagious\"--spread from cell-to-cell like a virus--creating an \"oncogenic/mutagenic\" field promoting widespread DNA damage.", "title": "Oxidative stress in cancer associated fibroblasts drives tumor-stroma co-evolution: A new paradigm for understanding tumor metabolism, the field effect and genomic instability in cancer cells." }, { "docid": "15615957", "text": "UNLABELLED Fruit and vegetable consumption has been inversely associated with the risk of chronic diseases including cancer and cardiovascular disease, with the beneficial effects attributed to a variety of protective antioxidants, carotenoids and phytonutrients. The objective of the present study was to determine the effect of supplementation with dehydrated concentrates from mixed fruit and vegetable juices (Juice Plus+R) on serum antioxidant and folate status, plasma homocysteine levels and markers for oxidative stress and DNA damage. Japanese subjects (n=60; age 27.8 yrs; BMI 22.1) were recruited to participate in a double-blind placebo controlled study and were randomized into 2 groups of 30, matched for sex, age, BMI and smoking status (39 males, 22 smokers; 21 females, 13 smokers). Subjects were given encapsulated supplements containing mixed fruit and vegetable juice concentrates or a matching placebo for 28 days, with blood and urine samples collected at baseline, day 14 and day 28 for analytical testing. Compared with the placebo, 28 day supplementation significantly increased the concentration of serum beta-carotene 528% (p<0.0001), lycopene 80.2% (p<0.0005), and alpha tocopherol 39.5% (p<0.0001). Serum folate increased 174.3% (p<0.0001) and correlated with a decrease in plasma homocysteine of -19.9% (p<0.03). Compared with baseline, measures of oxidative stress decreased with serum lipid peroxides declining -10.5% (p<0.02) and urine 8OHdG decreasing -21.1% (p<0.02). Evaluation of data from smokers only (n=17) after 28 days of active supplementation showed comparable changes. CONCLUSION In the absence of dietary modification, supplementation with the fruit and vegetable juice concentrate capsules proved to be a highly bioavailable source of phytonutrients.

Arterial stiffness and endothelial dysfunction are important risk factors in the aetiology of CHD. A range of methods exists to assess vascular function that may be used in nutritional science, including clinic and ambulatory blood pressure monitoring, pulse wave analysis, pulse wave velocity, flow-mediated dilatation and venous occlusion plethysmography. The present review focuses on the quantity and type of dietary fat and effects on blood pressure, arterial compliance and endothelial function. Concerning fat quantity, the amount of dietary fat consumed habitually appears to have little influence on vascular function independent of fatty acid composition, although single high-fat meals postprandially impair endothelial function compared with low-fat meals. The mechanism is related to increased circulating lipoproteins and NEFA which may induce pro-inflammatory pathways and increase oxidative stress. Regarding the type of fat, cross-sectional data suggest that saturated fat adversely affects vascular function whereas polyunsaturated fat (mainly linoleic acid (18 : 2n-6) and n-3 PUFA) are beneficial. EPA (20 : 5n-3) and DHA (22 : 6n-3) can reduce blood pressure, improve arterial compliance in type 2 diabetics and dyslipidaemics, and augment endothelium-dependent vasodilation. The mechanisms for this vascular protection, and the nature of the separate physiological effects induced by EPA and DHA, are priorities for future research.

METHODS A 24-week, randomized, open, parallel design was used. Seventy-four patients with Type 2 diabetes were randomly assigned to either the experimental group (n = 37), which received a vegetarian diet, or the control group (n = 37), which received a conventional diabetic diet. Both diets were isocaloric, calorie restricted (-500 kcal/day). All meals during the study were provided. The second 12 weeks of the diet were combined with aerobic exercise. Participants were examined at baseline, 12 weeks and 24 weeks. Primary outcomes were: insulin sensitivity measured by hyperinsulinaemic isoglycaemic clamp; volume of visceral and subcutaneous fat measured by magnetic resonance imaging; and oxidative stress measured by thiobarbituric acid reactive substances. Analyses were by intention to treat. RESULTS Forty-three per cent of participants in the experimental group and 5% of participants in the control group reduced diabetes medication (P < 0.001). Body weight decreased more in the experimental group than in the control group [-6.2 kg (95% CI -6.6 to -5.3) vs. -3.2 kg (95% CI -3.7 to -2.5); interaction group × time P = 0.001]. An increase in insulin sensitivity was significantly greater in the experimental group than in the control group [30% (95% CI 24.5-39) vs. 20% (95% CI 14-25), P = 0.04]. A reduction in both visceral and subcutaneous fat was greater in the experimental group than in the control group (P = 0.007 and P = 0.02, respectively). Plasma adiponectin increased (P = 0.02) and leptin decreased (P = 0.02) in the experimental group, with no change in the control group.

Differences between groups were greater after the addition of exercise training. Changes in insulin sensitivity and enzymatic oxidative stress markers correlated with changes in visceral fat. CONCLUSIONS A calorie-restricted vegetarian diet had greater capacity to improve insulin sensitivity compared with a conventional diabetic diet over 24 weeks. The greater loss of visceral fat and improvements in plasma concentrations of adipokines and oxidative stress markers with this diet may be responsible for the reduction of insulin resistance.

Behavioral and pharmacological therapies each appear modestly effective, but data are lacking on their separate and combined effects. OBJECTIVE To evaluate the clinical efficacy of behavioral and pharmacological therapies, singly and combined, for chronic tension-type headaches. DESIGN AND SETTING Randomized placebo-controlled trial conducted from August 1995 to January 1998 at 2 outpatient sites in Ohio. PARTICIPANTS Two hundred three adults (mean age, 37 years; 76% women) with diagnosis of chronic tension-type headaches (mean, 26 headache d/mo). INTERVENTIONS Participants were randomly assigned to receive tricyclic antidepressant (amitriptyline hydrochloride, up to 100 mg/d, or nortriptyline hydrochloride, up to 75 mg/d) medication (n = 53), placebo (n = 48), stress management (eg, relaxation, cognitive coping) therapy (3 sessions and 2 telephone contacts) plus placebo (n = 49), or stress management therapy plus antidepressant medication (n = 53). MAIN OUTCOME MEASURES Monthly headache index scores calculated as the mean of pain ratings (0-10 scale) recorded by participants in a daily diary 4 times per day; number of days per month with at least moderate pain (pain rating >/=5), analgesic medication use, and Headache Disability Inventory scores, compared by intervention group. RESULTS Tricyclic antidepressant medication and stress management therapy each produced larger reductions in headache activity, analgesic medication use, and headache-related disability than placebo, but antidepressant medication yielded more rapid improvements in headache activity. Combined therapy was more likely to produce clinically significant (>/=50%) reductions in headache index scores (64% of participants) than antidepressant medication (38% of participants; P =.006), stress management therapy (35%; P =.003), or placebo (29%; P =.001).

With the rising prevalence of type 2 diabetes mellitus and obesity in women of childbearing age, diabetes mellitus-induced birth defects have become an increasingly significant public health problem. Maternal diabetes mellitus in vivo and high glucose in vitro induce yolk sac injuries by damaging the morphologic condition of cells and altering the dynamics of organelles. The yolk sac vascular system is the first system to develop during embryogenesis; therefore, it is the most sensitive to hyperglycemia. The consequences of yolk sac injuries include impairment of nutrient transportation because of vasculopathy. Although the functional relationship between yolk sac vasculopathy and structural birth defects has not yet been established, a recent study reveals that the quality of yolk sac vasculature is related inversely to embryonic malformation rates. Studies in animal models have uncovered key molecular intermediates of diabetic yolk sac vasculopathy, which include hypoxia-inducible factor-1α, apoptosis signal-regulating kinase 1, and its inhibitor thioredoxin-1, c-Jun-N-terminal kinases, nitric oxide, and nitric oxide synthase. Yolk sac vasculopathy is also associated with abnormalities in arachidonic acid and myo-inositol. Dietary supplementation with fatty acids that restore lipid levels in the yolk sac lead to a reduction in diabetes mellitus-induced malformations. Although the role of the human yolk in embryogenesis is less extensive than in rodents, nevertheless, human embryonic vasculogenesis is affected negatively by maternal diabetes mellitus.

NaHS (50 µM, an H(2)S donor) had no significant effect on the resting calcium level, electrically induced (EI) calcium transients, and cell contractility in ventricular myocytes. Stimulating endogenous NO production with l-arginine or exogenous application of NO donors [sodium nitroprusside (SNP) and 2-(N,N-diethylamino)-diazenolate-2-oxide] decreased myocyte twitch amplitudes accompanied by slower velocities of both cell contraction and relaxation. Surprisingly, NaHS reversed the negative inotropic and lusitropic effects of the above three NO-increasing agents. In addition, the mixture of SNP + NaHS increased, whereas SNP alone decreased, the resting calcium level and the amplitudes of EI calcium transients. Angeli's salt, a nitroxyl anion (HNO) donor, mimicked the effect of SNP + NaHS on calcium handling and myocyte contractility.

S-Nitrosylation, the reversible post-translational modification of selective cysteine residues in proteins, has emerged as an important mechanism by which NO acts as a signaling molecule. The occurrence of S-nitrosylation in the spinal cord and its targets that may modulate pain transmission remain unclarified. The \"biotin-switch\" method and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry were employed for identifying S-nitrosylated proteins. RESULTS Here we show that actin was a major protein S-nitrosylated in the spinal cord by the NO donor, S-nitroso-N-acetyl-DL-penicillamine (SNAP). Interestingly, actin was S-nitrosylated, more in the S2 fraction than in the P2 fraction of the spinal homogenate. Treatment of PC12 cells with SNAP caused rapid S-nitrosylation of actin and inhibited dopamine release from the cells. Just like cytochalasin B, which depolymerizes actin, SNAP decreased the amount of filamentous actin cytoskeleton just beneath the membrane. The inhibition of dopamine release was not attenuated by inhibitors of soluble guanylyl cyclase and cGMP-dependent protein kinase.

We identified seven operational taxonomic units associated with PWV after adjusting for covariates and multiple testing-two belonging to the Ruminococcaceae family. Associations between microbe abundances, microbe diversity, and PWV remained significant after adjustment for levels of gut-derived metabolites (indolepropionate, trimethylamine oxide, and phenylacetylglutamine). We linearly combined the PWV-associated gut microbiome-derived variables and found that microbiome factors explained 8.3% (95% confidence interval 4.3-12.4%) of the variance in PWV. A formal mediation analysis revealed that only a small proportion (5.51%) of the total effect of the gut microbiome on PWV was mediated by insulin resistance and visceral fat, c-reactive protein, and cardiovascular risk factors after adjusting for age, body mass index, and mean arterial pressure. Conclusions Gut microbiome diversity is inversely associated with arterial stiffness in women. The effect of gut microbiome composition on PWV is only minimally mediated by MetS. This first human observation linking the gut microbiome to arterial stiffness suggests that targeting the microbiome may be a way to treat arterial ageing.", "title": "Gut microbial diversity is associated with lower arterial stiffness in women" }, { "docid": "16252863", "text": "The list of preventable and reversible risk factors for atherosclerotic cardiovascular disease continues to grow.

The left ureter of the rats was sutured with 4-zero polyglactin sutures. Medications were given 3 days before obstruction and continued for 15 days. Dimercaptosuccinic acid renal scintigraphy was performed before obstruction and on day 15. Rats were sacrificed on day 15 and histopathological examinations were done. We biochemically assessed oxidative stress markers (myeloperoxidase and malondialdehyde), sulfhydryl and total nitrite for lipid peroxidation, oxidative protein damage and antioxidant levels, respectively. RESULTS On pathological examination inflammation and tubular epithelial damage in the N-acetylcysteine and montelukast sodium groups were less than in the placebo group (p <0.05). No difference was seen in normal kidneys. Myeloperoxidase, malondialdehyde and total nitrite levels in the N-acetylcysteine group, and myeloperoxidase and malondialdehyde levels in the montelukast sodium group were lower than in the placebo group (p <0.05). No statistical difference was seen in sulfhydryl levels (p >0.05) or among the N-acetylcysteine, montelukast sodium and placebo groups on scintigraphy (p >0.05).

[ { "docid": "396657", "text": "The study of technical analysis is generally used (sometimes successfully) to time the markets. There are many aspects to technical analysis, but the simplest form is to look for uptrends and downtrends in the charts. Generally higher highs and higher lows is considered an uptrend. And lower lows and lower highs is considered a downtrend. A trend follower would go with the trend, for example see a dip to the trend-line and buy on the rebound. A simple strategy for this is shown in the chart below: I would be buying this stock when the price hits or gets very close to the trendline and then it bounces back above it. I would then have sold this stock once it has broken through below the trendline. This may also be an appropriate time if you were looking to short this stock. Other indicators could also be used in combination for additional confirmation of what is happening to the price. Another type of trader is called a bottom fisher. A bottom fisher would wait until a break above the downtrend line (second chart) and buy after confirmation of a higher high and possibly a higher low (as this could be the start of a new uptrend). There are many more strategies dealing with the study of technical analysis, and if you are interested you would need to find and learn about ones that suit your investment styles, whether you prefer short term trading or longer term investing, and your appetite for risk. You can develop strategies using various indicators and then paper trade or backtest these strategies. You can also manually backtest a strategy in most charting packages. You can go back in time on the chart so that the right side of the chart shows a date in the past (say one year ago or 10 years ago), then you can click forward one day at a time (or one week at a time if using weekly charts). With your indicators on the chart you can do virtual trades to buy or sell whenever a signal is given as you move forward in time. This way you may be able to check years of data in a day to see if your strategy works. Whatever you do, you need to document your strategies in writing in a written trading or investment plan together with a risk management strategy. You should always follow the rules in your written plan to avoid you making decisions based on emotions. By backtesting or paper trading your strategies it will give you confidence that they will work over the long term. There is a lot of work involved at the start, but once you have developed a documented strategy that has been thoroughly backtested, it will take you minimal time to successfully manage your investments.

For my longer term investing (positions held from months to years) I spend about an hour per week and have been averaging over 25% over the last 4 years. Technical Analysis does work for those who have a documented plan, have approached it in a systematic way and use risk management to protect their existing and future capital.

They're called \"\"market makers\"\". Their value for X% is somewhere on the scale of 1% (that is to say: a scale at which almost everything is \"\"volatile\"\"), but they use leverage, shorting and hedging to complicate things to the point where it's nothing like a simple as making a 1% profit every time they trade. Their actions tend to reduce volatility and increase liquidity. The reason you can't do this is that you don't have enough capital to do what market makers do, and you don't receive any advantages that the exchange might offer to official market makers in return for them contracting to always make both buy bids and sell offers (at different prices, hence the \"\"bid-offer spread\"\"). They have to be able to cover large short-term losses on individual stocks, but when the stock doesn't move too much they do make profits from the spread. The reason you can't just buy a lot of volatile stocks \"\"assuming I don't make too many poor choices\"\", is that the reason the stocks are volatile is that nobody knows which ones are the good choices and which ones are the poor choices. So if you buy volatile stocks then you will buy a bunch of losers, so what's your strategy for ensuring there aren't \"\"too many\"\"? Supposing that you're going to hold 10 stocks, with 10% of your money in each, what do you do the first time all 10 of them fall the day after you bought them? Or maybe not all 10, but suppose 75% of your holdings give no impression that they're going to hit your target any time soon. Do you just sit tight and stop trading until one of them hits your X% target (in which case you start to look a little bit more like a long-term investor after all), or are you tempted to change your strategy as the months and years roll by? If you will eventually sell things at a loss to make cash available for new trades, then you cannot assess your strategy \"\"as if\"\" you always make an X% gain, since that isn't true. If you don't ever sell at a loss, then you'll inevitably sometimes have no cash to trade with through picking losers. The big practical question then is when that state of affairs persists, for how long, and whether it's in force when you want to spend the money on something other than investing. So sure, if you used a short-term time machine to know in advance which volatile stocks are the good ones today, then it would be more profitable to day-trade those than it would be to invest for the long term. Investing on the assumption that you'll only pick short-term winners is basically the same as assuming you have that time machine ;-) There are various strategies for analysing the market and trying to find ways to more modestly do what market makers do, which is to take profit from the inherent volatility of the market. The simple strategy you describe isn't complete and cannot be assessed since you don't say how to decide what to buy, but the selling strategy \"\"sell as soon as I've made X% but not otherwise\"\" can certainly be improved. If you're keen you can test a give strategy for yourself using historical share price data (or current share price data: run an imaginary account and see how you're doing in 12 months). When using historical data you have to be realistic about how you'd choose what stocks to buy each day, or else you're just cheating at solitaire. When using current data you have to beware that there might not be a major market slump in the next 12 months, in which case you won't know how your strategy performs under conditions that it inevitably will meet eventually if you run it for real. You also have to be sure in either case to factor in the transaction costs you'd be paying, and the fact that you're buying at the offer price and selling at the bid price, you can't trade at the headline mid-market price.

As a general rule, using (3) is the safest regardless of what and how you trade because you get price guarantee in trade for execution guarantee. In the case of mid to longer term trading (1 week+) any of those points is viable, depending on how you want to do things, what your style is and what is the most comfortable for you. A few remarks though: (2) are market orders, so if the open is quite the ride and you are in the back of the execution queue, you can get significant slippage. (1) may require (live) data of the post-market session, which is often not easy to come by for the entire US stock universe. Depending on your physical execution method (phone, fax, online), you may lack accurate information of the post-market. If you want to execute orders based on RTH and only want to do that after hours because of personal schedule constraints, this is not really important. Personally I would always recommend (3), independent of the use case because it allows you more control over your orders and their fills.

The price, called the \"\"strike price\"\" is fixed when you buy the option. Let's run through an example - AAPL trades @ $259. You think it's going up over the next year, and you decide to buy the $280 Jan11 call for $12. Here are the details of this trade. Your cost is $1200 as options are traded on 100 shares each. You start to have the potential to make money only as Apple rises above $280 and the option trades \"\"in the money.\"\" It would take a move to $292 for you to break even, but after that, you are making $100 for each dollar it goes higher. At $300, your $1200 would be worth $2000, for example. A 16% move on the stock and a 67% increase on your money. On the other hand, if the stock doesn't rise enough by January 2011, you lose it all. A couple points here - American options are traded at any time. If the stock goes up next week, your $1200 may be worth $1500 and you can sell. If the option is not \"\"in the money\"\" its value is pure time value. There have been claims made that most options expire worthless. This of course is nonsense, you can see there will always be options with a strike below the price of the stock at expiration and those options are \"\"in the money.\"\" Of course, we don't know what those options were traded at. On the other end of this trade is the option seller. If he owns Apple, the sale is called a \"\"covered call\"\" and he is basically saying he's ok if the stock goes up enough that the buyer will get his shares for that price. For him, he knows that he'll get $292 (the $280, plus the option sale of $12) for a stock that is only $259 today. If the stock stays under $280, he just pocketed $12, 4.6% of the stock value, in just 3 months. This is why call writing can be a decent strategy for some investors. Especially if the market goes down, you can think of it as the investor lowering his cost by that $12. This particular strategy works best in a flat to down market. Of course in a fast rising market, the seller misses out on potentially high gains. (I'll call it quits here, just to say a Put is the mirror image, you have the right to sell a stock at a given price. It's the difference similar to shorting a stock as opposed to buying it.) If you have a follow up question - happy to help. EDIT - Apple closed on Jan 21, 2011 at $326.72, the $280 call would have been worth $46.72 vs the purchase price of $12. Nearly 4X return (A 289% gain) in just over 4 months for a stock move of 26%. This is the leverage you can have with options. Any stock could just as easily trade flat to down, and the entire option premium, lost.\"", "title": "" }, { "docid": "69395", "text": "\"Your plan already answers your own question in the best possible way: If you want to be able to make the most possible profit from a large downward move in a stock (in this case, a stock that tracks gold), with a limited, defined risk if there is an upward move, the optimal strategy is to buy a put option. There are a few Exchange Traded Funds (ETFs) that track the price of gold. think of them as stocks that behave like gold, essentially. Two good examples that have options are GLD and IAU. (When you talk about gold, you'll hear a lot about futures. Forget them, for now. They do the same essential thing for your purposes, but introduce more complexity than you need.) The way to profit from a downward move without protection against an upward move is by shorting the stock. Shorting stock is like the opposite of buying it. You make the amount of money the stock goes down by, or lose the amount it goes up by. But, since stocks can go up by an infinite amount, your possible loss is unlimited. If you want to profit on a large downward move without an unlimited loss if you're wrong and it goes up, you need something that makes money as the stock drops, but can only lose so much if it goes up. (If you want to be guaranteed to lose nothing, your best investment option is buying US Treasuries, and you're technically still exposed to the risk that US defaults on its debt, although if you're a US resident, you'll likely have bigger problems than your portfolio in that situation.) Buying a put option has the exact asymmetrical exposure you want. You pay a limited premium to buy it, and at expiration you essentially make the full amount that the stock has declined below the strike price, less what you paid for the option. That last part is important - because you pay a premium for the option, if it's down just a little, you might still lose some or all of what you paid for it, which is what you give up in exchange for it limiting your maximum loss. But wait, you might say. When I buy an option, I can lose all of my money, cant I? Yes, you can. Here's the key to understanding the way options limit risk as compared to the corresponding way to get \"\"normal\"\" exposure through getting long, or in your case, short, the stock: If you use the number of options that represent the number of shares you would have bought, you will have much, much less total money at risk. If you spend the same \"\"bag 'o cash\"\" on options as you would have spent on stock, you will have exposure to way more shares, and have the same amount of money at risk as if you bought the stock, but will be much more likely to lose it. The first way limits the total money at risk for a similar level of exposure; the second way gets you exposure to a much larger amount of the stock for the same money, increasing your risk. So the best answer to your described need is already in the question: Buy a put. I'd probably look at GLD to buy it on, simply because it's generally a little more liquid than IAU. And if you're new to options, consider the following: \"\"Paper trade\"\" first. Either just keep track of fake buys and sells on a spreadsheet, or use one of the many online services where you can track investments - they don't know or care if they're real or not. Check out www.888options.com. They are an excellent learning resource that isn't trying to sell you anything - their only reason to exist is to promote options education. If you do put on a trade, don't forget that the most frustrating pitfall with buying options is this: You can be basically right, and still lose some or all of what you invest. This happens two ways, so think about them both before you trade: If the stock goes in the direction you think, but not enough to make back your premium, you can still lose. So you need to make sure you know how far down the stock has to be to make back your premium. At expiration, it's simple: You need it to be below the strike price by more than what you paid for the option. With options, timing is everything. If the stock goes down a ton, or even to zero - free gold! - but only after your option expires, you were essentially right, but lose all your money. So, while you don't want to buy an option that's longer than you need, since the premium is higher, if you're not sure if an expiration is long enough out, it isn't - you need the next one. EDIT to address update: (I'm not sure \"\"not long enough\"\" was the problem here, but...) If the question is just how to ensure there is a limited, defined amount you can lose (even if you want the possible loss to be much less than you can potentially make, the put strategy described already does that - if the stock you use is at $100, and you buy a put with a 100 strike for $5, you can make up to $95. (This occurs if the stock goes to zero, meaning you could buy it for nothing, and sell it for $100, netting $95 after the $5 you paid). But you can only lose $5. So the put strategy covers you. If the goal is to have no real risk of loss, there's no way to have any real gain above what's sometimes called the \"\"risk-free-rate\"\". For simplicity's sake, think of that as what you'd get from US treasuries, as mentioned above. If the goal is to make money whether the stock (or gold) goes either up or down, that's possible, but note that you still have (a fairly high) risk of loss, which occurs if it fails to move either up or down by enough. That strategy, in its most common form, is called a straddle, which basically means you buy a call and a put with the same strike price. Using the same $100 example, you could buy the 100-strike calls for $5, and the 100-strike puts for $5. Now you've spent $10 total, and you make money if the stock is up or down by more than $10 at expiration (over 110, or under 90). But if it's between 90 and 100, you lose money, as one of your options will be worthless, and the other is worth less than the $10 total you paid for them both.\"", "title": "" }, { "docid": "448952", "text": "I don't think that the trading volume would impact a broker's ability to find shares to short.

I only really bet on rugby and soccer though, so team sports may be a bit less prone to corruption from the bookmakers. I'm not saying I think this is a safe way to do business though, I don't think day trading is either. I think they are both speculation. I just think that sports betting has a lot more for a speculator to work with before they develop a strategy. For instance, I always bet on New Zealand winning a rugby game, their players line up as the top in their respective positions and their game strategy essentially has the rules of the game exploited to the maximum. All of the data on this team based on their past performance is actually applicable to their future performance, skilled players usually continue to be so up till a certain age, skilled coaches who stay in their position mean no variation in team strategy. That makes me feel confident that even though New Zealand might lose a game here or there, that they will continue to be winners, and even though the gains on their wins aren't much, consistently winning with them over time builds up to a nice bit of profit.

How quickly does short float ratio/percent change?

Your odds are better if the particular stock has a large float (i.e. a large number of shares that are actually available for trading) and its short ratio is low (which means relatively few shares are currently being sold short). Also, a large brokerage may be more likely to have access to the shares than a small niche-market broker. The example you've given, Angie's List (ANGI) is a $600M small-cap with a comparatively low float, and though I haven't been able to glean the short ratio, it appears that a lot of investors are bearish on this stock and probably already had the same idea to short it.

Over long horizons, you absolutely want to minimise the expense ratio – a seemingly puny 2% fee p.a. can cost you a third of your savings over 35 years. Over short horizons, the cost of trading in and trading out might matter more. A mutual fund might be front-loaded, i.e. charge a fixed initial percentage when you first purchase it. ETFs, traded daily on an exchange just like a stock, don't have that. What you'll pay there is the broker commission, and the bid-ask spread (and possibly any premium/discount the ETF has vis-a-vis the underlying asset value). Another thing to keep in mind is tracking error: how closely does the fond mirror the underlying index it attempts to track? More often than not it works against you. However, not sure there is a systematic difference between ETFs and funds there. Size and age of a fund can matter, indeed - I've had new and smallish ETFs that didn't take off close down, so I had to sell and re-allocate the money. Two more minor aspects: Synthetic ETFs and lending to short sellers. 1) Some ETFs are synthetic, that is, they don't buy all the underlying shares replicating the index, actually owning the shares. Instead, they put the money in the bank and enter a swap with a counter-party, typically an investment bank, that promises to pay them the equivalent return of holding that share portfolio. In this case, you have (implicit) credit exposure to that counter-party - if the index performs well, and they don't pay up, well, tough luck. The ETF was relying on that swap, never really held the shares comprising the index, and won't necessarily cough up the difference. 2) In a similar vein, some (non-synthetic) ETFs hold the shares, but then lend them out to short sellers, earning extra money. This will increase the profit of the ETF provider, and potentially decrease your expense ratio (if they pass some of the profit on, or charge lower fees). So, that's a good thing. In case of an operational screw up, or if the short seller can't fulfil their obligations to return the shares, there is a risk of a loss. These two considerations are not really a factor in normal times (except in improving ETF expense ratios), but during the 2009 meltdown they were floated as things to consider. Mutual funds and ETFs re-invest or pay out dividends. For a given mutual fund, you might be able to choose, while ETFs typically are of one type or the other. Not sure how tax treatment differs there, though, sorry (not something I have to deal with in my jurisdiction).

Note, however, that the price is broadly still a little higher than it was before the spike as a result of this change in sentiment. Looking at the price trends on Bloomberg (https://www.bloomberg.com/quote/CDNA:US) the price had been steadily falling for the year prior to the spike but was levelling out at just over $1 in the few months immediately prior to the spike. The increased interest in the sector and the stock likely added to a general change in the direction of the price trend and caused traders (as opposed to investors) to believe that there was a change in the price trend. This will have lead to them trading the stock more heavily intraday exacerbating the spike. Note that there traders will include HFT bots as well as human traders. You question the legality of this volume increase but the simple answer is that we may never know if it was the target of traders manipulating the price or a case of insider trading. What we can see is that (taking \"\"animal spirits\"\" into account) without any evidence of illegality there are plenty of potential reasons why the spike may have occurred. Spikes are common where traders perceive a change in a trend as they rush to cash in on the change before other traders can and then sell out quickly when they realise that the price is fundamentally out of sync with the firm's underlying position. You yourself say that you have been watching the stock for some time and, by that fact alone, it is likely that others are for the same reasons that you are. Otherwise you wouldn't be looking at it.

However, I felt it valuable to explain what would happen were you to fall for this. It's not all that hard to understand, but it involves understanding some of the time delays that exist in modern banking today. The most important thing to understand is that depositing a check does not actually put dollars in your account, even though it appears to. A check is not legal tender for debts public and private. It's a piece of paper known as a \"\"bill of exchange.\"\" It's an authorization for a payee (you), to request that their bank pay you the amount on the check. A transaction made with a check does not actually draw to a close until your bank and their bank communicate and cause the actual transfer of funds to take place. This process is called \"\"clearing\"\" the check. Despite living in the modern times, this process is slow. It can take 7-10 days to clear a check (especially if it is an international bank). This is not good for the banking business. You can imagine how difficult it would be to tell a poor client, who is living paycheck to paycheck, that he can't have his pay until the check clears a week later. Banks have an interest in hiding this annoying feature of the modern banking system, so they do. When you deposit a check, the bank will typically advance you the money (an interest free loan, in effect) while the check \"\"floats\"\" (i.e. until it clears). This creates the illusion that the money is actually in your account for most intents and purposes. (presumably a bank would distinguish between the floating check and a cleared check if you tried to close out your account, but otherwise it looks and feels like the money is in your hands). Of course, if the check is dishonored (because the payer had insufficient funds, or the account simply did not exist), your bank will not get the money. At this moment, they will cancel any advances you received and notify you that the check bounced. Again, this happens 7-10 days later. The general pattern of this scam is that they will pay you by a method which clears slowly, like a check. They will then ask you to withdraw the money using a faster clearing method (like a wire transfer or withdrawing the cash). Typically they will be encouraging you to move quickly (they are on a timetable... when their check bounces, the game is up!) At this time, it will appear as though the account has a positive balance, but in fact it has a negative balance plus an advance on the check. This looks great until 7-10 days later, when the check bounces. At that time, the bank will cancel the advance, and reality will set in. You will now have an open bank account, legally opened by you in your own name, which is deeply in debt. Meanwhile, the scammer walks away with all the money that you sent them (which cleared quickly). There are many variants which can hide the details. Some can play games with check kiting to try to make your first check clear (then try to rope you in for a more painful hit). Some will change the instruments they use (checks are the easy ones, so they're simply most common).

Subjective human demand is the only thing that gives anything value. This subjectivity is different person to person and can change very quickly. Historically there are two main uses for gold: jewelry and money. How can you tell when a particular type of money is undervalued? It disappears from circulation since people prefer to use money that is overvalued. This phenomenon is paraphrased in Gresham's Law: Bad money drives out good money. The Coinage Act of 1792 established the US dollar as 371.25 grains of silver or 24.75 grains of gold. This established a government ratio of 15 ounces of silver to 1 ounce of gold. In the late 18th century there was a large production of silver from Mexico and the market ratio of silver to gold increased to 15.75 to 1 by 1805. The government ratio, however, was still 15 to 1. This was enough incentive for people to exchange their silver coins for gold coins at the government ratio, melt the gold, and sell the gold bullion overseas at the market value. Thus, gold coins disappeared from circulation as people either hoarded the gold or sent it abroad. People used the overvalued silver coins (i.e. the \"\"bad\"\" money) domestically and gold coins disappeared from the market. In an attempt to correct the problem of disappearing gold coins the Coinage Act of 1834 was enacted. It kept the US dollar at 371.25 grains of silver but changed the definition to 23.2 grains of gold which established a government ratio of 16 to 1. This was close to the market ratio of gold to silver at the time so both gold and silver coins appeared in circulation again. The gold rush of 1849 produced a lot of gold and the market ratio of silver to gold became 15.46 to 1. Now gold was overvalued so people began exchanging their gold coins for silver coins at the government ratio, melt the silver, and sell the silver bullion overseas at the market value. People used the overvalued gold coins (i.e. the \"\"bad\"\" money) domestically and silver coins disappeared from the market. When you see gold circulating everywhere you will know it is overvalued compared to other types of money. Paper money always drives gold out of circulation since the market ratio of paper to gold severely under values gold.

Here's the deal, it probably DOES help your credit slightly to pay it multiple times per month if it isn't a hassle, but the bump is likely to be minimal and very temporary. Here's why: A key component of your score is your credit usage ratio. That is the ratio of how much of your credit limits you are using. You want to keep this number down as low as possible. Now here is where it gets tricky. Although you have a grace period to pay off your card with no interest, the credit card companies don't generally report the balance as of the due date. They either report the high balance or an average balance over the month. That is, it is based on how much you use, not how much balance you carry over each month. It isn't very intuitive, but that's just how it is. So technically, keeping that balance lower over the course of the month WILL probably help you, but the credit usage ratio is generally a rolling average over the last x months, so the effect will wear off quickly. So it is probably not worth doing unless you know you are going to apply for a loan in the next 6 months and need a temporary, small bump. Another consideration is that paying early provides no real financial benefit in terms of finance charges, but you are giving up liquidity which does have some value. 1) You probably could get at least a little interest for keeping the money in your account a few more weeks. 2) If you have a major financial emergency, e.g. broken down car, you might appreciate the fact that you kept your options open to carry that balance over a month.", "title": "" }, { "docid": "296420", "text": "It depends a lot on your investment period and the quality of the bonds that you want to invest.

Each county assessor's office reviews all recorded deeds for that county to determine which properties require reappraisal under the law. The county assessors may also discover changes in ownership through other means, such as taxpayer self-reporting, field inspections, review of building permits and newspapers. Once the county assessor has determined that a change in ownership has occurred, Proposition 13 requires the county assessor to reassess the property to its current fair market value as of the date ownership changed. Since property taxes are based on the assessed value of a property at the time of acquisition, a current market value that is higher than the previously assessed Proposition 13 adjusted base year value will increase the property taxes. Conversely, if the current market value is lower than the previously assessed Proposition 13 adjusted base year value, then the property taxes on that property will decrease. Only that portion of the property that changes ownership, however, is subject to reappraisal. For example, if 50 percent of the property is transferred, the assessor will reassess only 50 percent of the property at its current fair market value as of the date of the transfer, and deduct 50 percent from any existing Proposition 13 base year value.

The cluster of workers had been experiencing similar symptoms, including fatigue, pain, numbness, and tingling in their extremities as well as weakness. The symptoms were described as more sensory than motor, and all patients had evidence of polyradiculoneuropathy with signs of nerve root irritation. An epidemiological investigation revealed that the only commonality between cases was their exposure to a pork brain extraction procedure involving compressed air. As relatives of the cases remained asymptomatic and all cultures for known pathogens were negative, the etiology of the syndrome seemed not to be infectious. Clinically, the syndrome was most akin to chronic inflammatory demyelinating polyneuropathy. Laboratory tests corroborated the clinical findings, revealing inflammation of peripheral nerves and nerve roots; however, these cases also had features clinically distinct from chronic inflammatory demyelinating polyneuropathy as well as laboratory testing revealing a novel immunoglobulin G immunostaining pattern. This suggested that the observed inflammation was the result of 1 or more unidentified antigens.

SEARCH STRATEGY: We searched The Cochrane Library, MEDLINE, EMBASE, LILACS, the Science Citation Index Expanded, and Conference Proceedings Citation Index-Science (to January 2011). We scanned bibliographies of relevant publications and asked experts and pharmaceutical companies for additional trials. SELECTION CRITERIA: We included randomised trials that compared vitamin D at any dose, duration, and route of administration versus placebo or no intervention. Vitamin D could have been administered as supplemental vitamin D (vitamin D(3) (cholecalciferol) or vitamin D(2) (ergocalciferol)) or an active form of vitamin D (1α-hydroxyvitamin D (alfacalcidol) or 1,25-dihydroxyvitamin D (calcitriol)). DATA COLLECTION AND ANALYSIS: Six authors extracted data independently. Random-effects and fixed-effect model meta-analyses were conducted. For dichotomous outcomes, we calculated the risk ratios (RR). To account for trials with zero events, meta-analyses of dichotomous data were repeated using risk differences (RD) and empirical continuity corrections. Risk of bias was considered in order to minimise risk of systematic errors. Trial sequential analyses were conducted to minimise the risk of random errors. MAIN RESULTS: Fifty randomised trials with 94,148 participants provided data for the mortality analyses. Most trials included elderly women (older than 70 years). Vitamin D was administered for a median of two years. More than one half of the trials had a low risk of bias. Overall, vitamin D decreased mortality (RR 0.97, 95% confidence interval (CI) 0.94 to 1.00, I(2) = 0%).

Aspalathus linearis (Rooibos), which has been reported to aid stress-related symptoms linked to metabolic diseases, contains a wide spectrum of bioactive phenolic compounds of which aspalathin is unique. In this study the inhibitory effects of Rooibos and the dihydrochalcones, aspalathin and nothofagin, were investigated on adrenal steroidogenesis. The activities of both cytochrome P450 17α-hydroxylase/17,20 lyase and cytochrome P450 21-hydroxylase were significantly inhibited in COS-1 cells. In order to study the effect of these compounds in H295R cells, a human adrenal carcinoma cell line, a novel UPLC-MS/MS method was developed for the detection and quantification of twenty-one steroid metabolites using a single chromatographic separation. Under both basal and forskolin-stimulated conditions, the total amount of steroids produced in H295R cells significantly decreased in the presence of Rooibos, aspalathin and nothofagin. Under stimulated conditions, Rooibos decreased the total steroid output 4-fold and resulted in a significant reduction of aldosterone and cortisol precursors. Dehydroepiandrosterone-sulfate levels were unchanged, while the levels of androstenedione (A4) and 11β-hydroxyandrostenedione (11βOH-A4) were inhibited 5.5 and 2.3-fold, respectively. Quantification of 11βOH-A4 showed this metabolite to be a major product of steroidogenesis in H295R cells and we confirm, for the first time, that this steroid metabolite is the product of the hydroxylation of A4 by human cytochrome P450 11β-hydroxylase. Taken together our results demonstrate that Rooibos, aspalathin and nothofagin influence steroid hormone biosynthesis and the flux through the mineralocorticoid, glucocorticoid and androgen pathways, thus possibly contributing to the alleviation of negative effects arising from elevated glucocorticoid levels.

METHODS: Twenty-four healthy volunteers were randomly assigned to a normal daily diet (control group) or a normal diet with WBM. The subjects in the active group (n = 12, 41.4 ± 11.3 y old) consumed 100 g of blanched WBM daily with their normal diet for 1 wk, whereas those in the control group consumed their normal diet (n = 12, 43.5 ± 12.5 y old) without WBM. Saliva was collected before and after commencement of the study and every week thereafter for 3 wk.

RESULTS: There was no significant difference between pre- and postdietary mushroom intakes for all indices in the control group (P > 0.05). In contrast, the mean sIgA secretion rate increased significantly at weeks 1 and 2 by 53% and 56%, respectively, compared with that at week 0 (P < 0.0005) in the WBM intake group and then returned to a baseline level at week 3.

Pretreatment of the cells with green tea extract attenuated the changes significantly. Among the green tea constituents, (-)-epigallocatechin gallate (EGCG) attenuated the ethanol cytotoxicity effectively, whereas L-theanine and caffeine had no effects. The ethanol cytotoxicity was also attenuated by alcohol dehydrogenase inhibitor 4-methyl pyrazol and GGT inhibitor acivicin as well as by thiol modulators such as S-adenosyl-L-methionine, N-acetyl-L-cysteine and glutathione. EGCG failed to prevent the intracellular glutathione loss caused by ethanol, but it appeared to be a strong GGT inhibitor. Therefore the cytoprotective effects of green tea could be attributed to the inhibition of GGT activity by EGCG. This study suggests that GGT inhibitors including EGCG may provide a novel strategy for attenuating ethanol-induced liver damage.", "title": "Effect of green tea and (-)-epigallocatechin gallate on ethanol-induced toxicity in HepG2 cells." }, { "docid": "MED-3318", "text": "Smoking is an established risk factor for pancreatic cancer; however, detailed examination of the association of smoking intensity, smoking duration, and cumulative smoking dose with pancreatic cancer is limited.

Smoking intensity effects were examined with an excess odds ratio model that was linear in pack-years and exponential in cigarettes smoked per day and its square. When compared with never smokers, current smokers had a significantly elevated risk (odds ratio (OR) = 1.77, 95% confidence interval (CI): 1.38, 2.26).

Risk more than 15 years after smoking cessation was similar to that for never smokers. Estimates of excess odds ratio per pack-year declined with increasing intensity, suggesting greater risk for total exposure delivered at lower intensity for longer duration than for higher intensity for shorter duration.

Two core statistics are the cancer incidence rate and the cancer mortality rate, which provide estimates of the average risk of acquiring and of dying from the disease, respectively. About 16% of the world's population is covered by registration systems that produce cancer incidence statistics, while mortality data are available for about 29%.

In general, the incidence is high (greater than 80 per 100,000) in developed regions of the world and low (less than 30 per 100,000), though increasing, in developing regions; the range of mortality rates is much less (approximately 6-23 per 100,000) because of the more favorable survival of breast cancer in (high-incidence) developed regions. The incidence of breast cancer is increasing almost everywhere. This unfavorable trend is due in part to increases in risk factors (decreased childbearing and breast-feeding, increased exogenous hormone exposure, and detrimental dietary and lifestyle changes, including obesity and less physical activity).

Anti-Gal is naturally produced also in apes and Old World monkeys. The ligand of anti-Gal is a carbohydrate antigen called the ‘α-gal epitope’ with the structure Galα1-3Galβ1-4GlcNAc-R. The α-gal epitope is present as a major carbohydrate antigen in non-primate mammals, prosimians and New World monkeys. Anti-Gal can contributes to several immunological pathogeneses. Anti-Gal IgE produced in some individuals causes allergies to meat and to the therapeutic monoclonal antibody cetuximab, all presenting α-gal epitopes. Aberrant expression of the α-gal epitope or of antigens mimicking it in humans may result in autoimmune processes, as in Graves' disease. α-Gal epitopes produced by Trypanosoma cruzi interact with anti-Gal and induce ‘autoimmune like’ inflammatory reactions in Chagas' disease. Anti-Gal IgM and IgG further mediate rejection of xenografts expressing α-gal epitopes. Because of its abundance, anti-Gal may be exploited for various clinical uses. It increases immunogenicity of microbial vaccines (e.g. influenza vaccine) presenting α-gal epitopes by targeting them for effective uptake by antigen-presenting cells. Tumour lesions are converted into vaccines against autologous tumour-associated antigens by intra-tumoral injection of α-gal glycolipids, which insert into tumour cell membranes. Anti-Gal binding to α-gal epitopes on tumour cells targets them for uptake by antigen-presenting cells. Accelerated wound healing is achieved by application of α-gal nanoparticles, which bind anti-Gal, activate complement, and recruit and activate macrophages that induce tissue regeneration.

The majority of these observations are anecdotal and often lack standardization.

A number of these effects are beneficial but, unfortunately, many responses are still characterized based on phenomenology and there is more speculation than substance. With respect to tumor biology, although many neoplastic lesions are immunogenic, tumor antigens frequently are self antigens and induce tolerance and many patients with cancer exhibit suppressed immune responses, including defective antigen presentation. Therefore, if and when mushroom extracts are effective, they more likely function as a result of improved antigen presentation by dendritic cells than by a direct cytopathic effect. In this review we attempt to place these data in perspective, with a particular focus on dendritic cell populations and the ability of mushroom extracts to modulate immunity.

IgE binding to αGal was inhibited by raw pork kidney extract (mean, 77%; range, 55-87%), which showed a high amount of αGal determinants. CONCLUSIONS: Pork or beef kidney anaphylaxis is related to αGal IgE.

Most of these patients had tolerated meat for many years previously. The implication is that some exposure in adult life had stimulated the production of these IgE antibodies. Objectives To investigate possible causes of this IgE antibody response, focusing on evidence related to tick bites, which are common in the region where these reactions occur. Methods Serum assays were carried out using biotinylated proteins and extracts bound to a streptavidin ImmunoCAP. Results Prospective studies on IgE antibodies in three subjects following tick bites showed an increase in IgE to alpha-gal of twenty-fold or greater. Other evidence included i) a strong correlation between histories of tick bites and IgE to alpha-gal (χ2=26.8, p<0.001), ii) evidence that these IgE antibodies are common in areas where the tick Amblyomma americanum is common, and iii) a significant correlation between IgE antibodies to alpha-gal and IgE antibodies to proteins derived from A. americanum (rs=0.75, p<0.001). Conclusion The results presented here provide evidence that tick bites are a cause, or possibly the only cause, of IgE specific for alpha-gal in this area of the United States.

We report here on an update of mortality in 510 workers employed in abattoirs and processing plants that almost exclusively handled pigs and pork products. METHODS: standardized mortality ratios (SMRs) were estimated for the cohort as a whole, and in subgroups defined by race and sex, using the corresponding US general population mortality rates for comparison. Study subjects were followed up from January 1950 to December 2006, during which time 45% of them died. RESULTS: mortality was significantly increased overall in the cohort. A statistically significant excess of deaths was observed for colon and lung cancers in the entire cohort, SMR=2.7 (95% CI, 1.2-5.1), SMR=1.8 (95% CI, 1.1-2.7), respectively. Significant SMRs in the cohort as a whole were also observed for senile and pre-senile psychotic conditions (SMR=5.1, 95% CI, 1.4-13.1), and pneumonia (SMR=2.6, 95% CI, 1.3-4.8). An observed excess of subarachnoid hemorrhage was seen mainly in whites (SMR=10.1, 95% CI, 1.2-36.3). There was a suggestion of an excess of deaths from ischemic heart disease also, but the elevated SMR was confined to men and was not statistically significant. CONCLUSION: this study confirms the excess occurrence of lung and colon cancers, and stroke previously reported in this occupational group. New findings are the excess of risk for senile and pre-senile psychotic conditions and pneumonia, which together with the excess of colon cancer appear specific for pig/pork workers, as they were not evident in much larger studies of workers in abattoirs and processing plants handling cattle and sheep. However, caution should be exercised in interpreting these findings, since some of them could have occurred by chance, resulting from our examination of a large number of causes of death in multiple study subgroups. For the moment, the significance of these findings remains unknown until they are confirmed in larger studies of adequate statistical power.

In this paper, we examined breast cancer incidence rates among non-Hispanic (NH) white women from 2003 to 2007 to determine whether the decrease in breast cancer incidence rates indeed persisted through 2007. In addition, we present breast cancer incidence trends for NH black and Hispanic women and postmenopausal hormone use for all three racial/ethnic groups. METHODS: Breast cancer incidence rates were calculated by race/ethnicity, age and ER status using data from the Surveillance, Epidemiology, and End Results (SEER) 12 registries for 2000 to 2007. Prevalence of postmenopausal hormone use was calculated using National Health Interview Survey data from 2000, 2005, and 2008. RESULTS: From 2003 to 2007, overall breast cancer incidence rates did not change significantly among NH white women in any age group.

The precise turning point for the epidemic and the antigens responsible for it remain obscure. OBJECTIVE: To evaluate how the prevalence of atopic disease has changed in terms of detectable sensitization to aeroallergens and dietary allergens in a cross-sectional comparison of subjects from birth cohorts more than 60 years apart. METHODS: We studied four groups of 100 subjects each (at ages 7, 27, 47 and 67 years), representing those born in 1990, 1963-66, 1943-46 and in 1923-26, respectively. Serum total and specific IgE concentrations against aeroallergens and dietary allergens were determined. A questionnaire elicited information on symptoms, allergic diseases and medication. RESULTS: The proportion of subjects with detectable IgE antibodies against aeroallergens increased consistently from the oldest to the youngest birth cohorts; chi2 trend=56.809, P<0.0001. Similar progression was not seen in sensitization to dietary allergens. The proportion of those with diagnosed asthma differed significantly (chi2=13.45, P=0.004) across the birth cohorts. The lowest prevalence of asthma and sensitization to dietary allergens was detected in those born in 1943-46, i.e. during or immediately after World War II. CONCLUSION: Prevalence of sensitization to airborne allergens, unlike that to dietary allergens, has increased over a long period of time.

This investigation evaluates the structural effect that stinging nettle spicules may have on the clinical manifestation of these symptoms. This hypothesis was investigated by exposing murine skin to stinging nettles and then evaluating the skin using electron microscopy. It was hypothesized that the mechanism of action of stinging nettles is both biochemical and mechanical, which may have clinical significance regarding treatment for acute exposure. METHODS: Fresh post-mortem dermis samples from the carcasses of genetically modified hairless mice were brushed under the stem and leaf of a stinging nettle plant, mimicking the clinical method of exposure a patient might experience. Another set of mouse skin samples was obtained but not exposed to the nettles. Both sets of skin samples were imaged with scanning electron microscopy. RESULTS: The skin samples that were not exposed to nettle leaves were uniform, with occasional striated hairs on the skin surface and no nettle spicules. The skin samples exposed to nettle leaves showed many smooth nettle spicules piercing the skin surface. A few spicules retained their bases, which appear empty of any liquid contents. CONCLUSIONS: The mechanism of action of stinging nettles dermatitis appears to be both biochemical and mechanical.

This review identifies and addresses some controversial occupational and clinical aspects of asbestos-related malignancies. METHODS: Papers published in English from 1980 to 2009 were retrieved from PubMed. A total of 307 original articles were identified and 159 were included. ASSESSMENT OF EXPOSURE: The retrospective assessment of exposure is usually performed by using questionnaires and job exposure matrices and by careful collection of medical history. In this way crucial information about manufacturing processes and specific jobs can be obtained. In addition, fibers and asbestos bodies are counted in lung tissue, broncho-alveolar lavage, and sputum, but different techniques and interlaboratory variability hamper the interpretation of reported measurements. SCREENING FOR MALIGNANCIES: The effectiveness of low-dose chest CT screening in exposed workers is debatable. Several biomarkers have also been considered to screen individuals at risk for lung cancer and mesothelioma but reliable signatures are still missing. ATTRIBUTION OF LUNG CANCER: Exposures correlating with lung cancer are high and in the same range where asbestosis occurs. However, the unresolved question is whether the presence of fibrosis is a requirement for the attribution of lung cancer to asbestos. The etiology of lung cancer is difficult to define in cases of low-level asbestos exposure and concurrent smoking habits. MESOTHELIOMA: The diagnosis of malignant mesothelioma may also be difficult, because of procedures in sampling, fixation, and processing, and uses of immunohistochemical probes. CONCLUSIONS: Assessment of exposure is crucial and requires accurate medical and occupational histories. Quantitative analysis of asbestos body burden is better performed in digested lung tissues by counting asbestos bodies by light microscopy and/or uncoated fibers by transmission electron microscopy. The benefits of screenings for asbestos-related malignancies are equivocal. The attribution of lung cancer to asbestos exposure is difficult in a clinical setting because of the need to assess asbestos body burden and the fact that virtually all these patients are also tobacco smokers or former smokers. Given the premise that asbestosis is necessary to causally link lung cancer to asbestos, it follows that the assessment of both lung fibrosis and asbestos body burden is necessary.", "title": "Occupational toxicology of asbestos-related malignancies." }, { "docid": "MED-3987", "text": "Background: Currently, there is a lack of clarity in the literature as to whether there is a definitive difference between the effects of vitamins D2 and D3 in the raising of serum 25-hydroxyvitamin D [25(OH)D].

When the frequency of dosage administration was compared, there was a significant response for vitamin D3 when given as a bolus dose (P = 0.0002) compared with administration of vitamin D2, but the effect was lost with daily supplementation. Conclusions: This meta-analysis indicates that vitamin D3 is more efficacious at raising serum 25(OH)D concentrations than is vitamin D2, and thus vitamin D3 could potentially become the preferred choice for supplementation. However, additional research is required to examine the metabolic pathways involved in oral and intramuscular administration of vitamin D and the effects across age, sex, and ethnicity, which this review was unable to verify.", "title": "Comparison of vitamin D2 and vitamin D3 supplementation in raising serum 25-hydroxyvitamin D status: a systematic review and meta-analysis" }, { "docid": "MED-2366", "text": "Glycoconjugates and their antibodies are vital components of host-tumor interaction. This review concentrates on the oncological implications of research concerning the alpha gal triad; the alpha 1-->3 galactosyl epitope (alpha Gal), the enzyme responsible for its construction, alpha 1,3 galactosyl transferase (alpha 1-3GT), and its associated antibody: anti-gal. Alpha gal epitopes, previously assumed to be absent from human tissue, have been demonstrated on several human cancer cell lines, senescent red blood cells, and Graves' disease thyrocytes. Alpha-gal presence on neoplastic lines is correlated with increased metastatic formation in animal models. The mechanisms of human response to these neoantigens are complex, as natural anti-gal antibodies exist in high titers in normal sera, thus predicting immunological recognition of cells expressing alpha gal epitopes. Hypotheses vary regarding the pathogenic contributions of metastasis-associated phenomena such as de novo expression of alpha gal and its unmasking by desialylation. The means by which alpha gal is sporadically expressed in human tissue remain unknown, as the galactosyl transferase which produces this epitope in constitutively expressive animals has undergone significant mutation at the genomic level in humans. Pathological re-expression is presumed to require permissive changes at a cellular level. Detailing these alterations is a prerequisite to the comprehension of the metastatic phenotype.

The prospects of purposefully harnessing such an anti-viral defense are under investigation. Here, long-term co-culture experiments were used to show that porcine endogenous retrovirus (PERV) transmission from pig to human cells is reduced to nearly undetectable levels by expressing human APOBEC3G in virus-producing pig kidney cells. Inhibition occurred by a deamination-independent mechanism, likely after particle production but before the virus could immortalize by integration into human genomic DNA. PERV inhibition did not require the DNA cytosine deaminase activity of APOBEC3G and, correspondingly, APOBEC3G-attributable hypermutations were not detected. In contrast, over-expression of the sole endogenous APOBEC3 protein of pigs failed to interfere significantly with PERV transmission. Together, these data constitute the first proof-of-principle demonstration that APOBEC3 proteins can be used to fortify the innate anti-viral defenses of cells to prevent the zoonotic transmission of an endogenous retrovirus. These studies suggest that human APOBEC3G-transgenic pigs will provide safer, PERV-less xenotransplantation resources and that analogous cross-species APOBEC3-dependent restriction strategies may be useful for thwarting other endogenous as well as exogenous retrovirus infections.", "title": "The Restriction of Zoonotic PERV Transmission by Human APOBEC3G" }, { "docid": "MED-3701", "text": "Estrogen synthesized in situ plays a more important role in breast cancer cell proliferation than does circulating estrogen. Aromatase is the enzyme that converts androgen to estrogen and is expressed at a higher level in breast cancer tissue than in surrounding noncancer tissue. A promising route of chemoprevention against breast cancer may be through the suppression of in situ estrogen formation using aromatase inhibitors. A diet high in fruits and vegetables may reduce the incidence of breast cancer, because they contain phytochemicals that can act as aromatase inhibitors. In our previous studies, we found that grapes and wine contain potent phytochemicals that can inhibit aromatase. We show that red wine was more effective than white wine in suppressing aromatase activity. Interestingly, our results from white wine studies suggest a weak inductive effect of alcohol on aromatase activity. On the other hand, the potent effect of anti-aromatase chemicals in red wine overcomes the weak inductive effect of alcohol in wine. Several purification procedures were performed on whole red wine to separate active aromatase inhibitors from non-active compounds. These techniques included liquid-liquid extraction, silica gel chromatography, various solid phase extraction (SPE) columns, and high performance liquid chromatography. An active Pinot Noir red wine SPE C18 column fraction (20% acetonitrile:water) was more effective than complete Pinot Noir wine in suppressing aromatase assay. This red wine extract was further analyzed in a transgenic mouse model in which aromatase was over-expressed in mammary tissue. Our gavaged red wine extract completely abrogated aromatase-induced hyperplasia and other neoplastic changes in mammary tissue.

The biokinetic variables were the areas under the curve (AUC) of plasma FRAP, ascorbic acid and urate that are above the pre-dose concentration, and the amounts excreted into urine within 24 h (Ae(0-24) ) of antioxidants as assayed by FRAP, ascorbic acid, uric acid, malondialdehyde (biomarker for oxidative stress), and hippuric acid (metabolite and potential biomarker for total polyphenol intake). RESULTS: HSE caused significantly higher plasma AUC of FRAP, an increase in Ae(0-24) of FRAP, ascorbic acid and hippuric acid, whereas malondialdehyde excretion was reduced.

This report investigates interactions among these variables. Patients and Methods A prospective study was performed of 1,490 women diagnosed and treated for early-stage breast cancer between 1991 and 2000. Enrollment was an average of 2 years postdiagnosis. Only seven women were lost to follow-up through December 2005. Results In univariate analysis, reduced mortality was weakly associated with higher vegetable-fruit consumption, increased physical activity, and a body mass index that was neither low weight nor obese. In a multivariate Cox model, only the combination of consuming five or more daily servings of vegetables-fruits, and accumulating 540+ metabolic equivalent tasks-min/wk (equivalent to walking 30 minutes 6 d/wk), was associated with a significant survival advantage (hazard ratio, 0.56; 95% CI, 0.31 to 0.98).

In the present study, we sought to determine the longitudinal course of alpha-Gal specific AB titers of all isotypes over 8 weeks among healthy adult subjects. Furthermore, we hypothesized that inflammatory bowel disease (IBD) patients display increased anti-Gal titers. MATERIALS AND METHODS: We drew serum from healthy probands (n=20) weekly for 8 weeks and obtained plasma samples of from patients suffering from Crohn's disease (n=20) and ulcerative colitis (n=20). We measured anti-Gal ABs of all isotypes and total immunoglobulin (Ig) content using an enzyme-linked immunosorbent assay technique. For statistical evaluation of the longitudinal titers, we calculated confidence intervals for the slopes of a random intercept model, comparing variances between and within the probands. For group comparisons, we performed paired student t-tests and Pearson correlations. RESULTS: Alpha-Gal specific IgG, IgM, IgD, and IgA titers remained unvaried within a narrow range upon longitudinal observation. Most probands did not display alpha-Gal specific IgE ABs. Crohn's disease patients showed highly increased alpha-Gal-specific IgA titers compared with control subjects (P<.01). CONCLUSION: Apart from IgE, alpha-Gal-specific ABs of all isotypes remained constant over longer time periods in healthy subjects. Thus, significant titer changes actually represent increased antigen exposure and a specific anti-alpha-Gal response.

METHODS AND RESULTS: To obtain insights into the role of MPs in atherogenesis, MP proteins were identified by tandem mass spectrometry, metabolite profiles were determined by high-resolution nuclear magnetic resonance spectroscopy, and antibody reactivity was assessed against combinatorial antigen libraries. Plaque MPs expressed surface antigens consistent with their leukocyte origin, including major histocompatibility complex classes I and II, and induced a dose-dependent stimulatory effect on T-cell proliferation. Notably, taurine, the most abundant free organic acid in human neutrophils, which scavenges myeloperoxidase-catalyzed free radicals, was highly enriched in plaque MPs. Moreover, fluorescent labeling of proteins on the MP surface suggested immunoglobulins to be trapped inside, which was confirmed by flow cytometry analysis on permeabilized and nonpermeabilized plaque MPs. Colabeling for CD14 and IgG established that more than 90% of the IgG containing MPs were CD14(+), indicating a macrophage origin.

Objective We sought to determine whether IgE antibodies to α-gal are present in sera from patients who report anaphylaxis or urticaria after eating beef, pork, or lamb. Methods Detailed histories were taken from patients presenting to the University of Virginia Allergy Clinic.

Tea is known to be a rich source of flavonoid antioxidants. However tea also contains a unique amino acid, L-theanine that may modulate aspects of brain function in humans. Evidence from human electroencephalograph (EEG) studies show that it has a direct effect on the brain (Juneja et al. Trends in Food Science & Tech 1999;10;199-204). L-theanine significantly increases activity in the alpha frequency band which indicates that it relaxes the mind without inducing drowsiness. However, this effect has only been established at higher doses than that typically found in a cup of black tea (approximately 20mg). The aim of the current research was to establish this effect at more realistic dietary levels. EEG was measured in healthy, young participants at baseline and 45, 60, 75, 90 and 105 minutes after ingestion of 50mg L-theanine (n=16) or placebo (n=19). Participants were resting with their eyes closed during EEG recording. There was a greater increase in alpha activity across time in the L-theanine condition (relative to placebo (p+0.05). A second study replicated this effect in participants engaged in passive activity. These data indicate that L-theanine, at realistic dietary levels, has a significant effect on the general state of mental alertness or arousal.

However, humans are genetically deficient in Neu5Gc production and instead metabolically accumulate Neu5Gc from dietary sources, particularly red meats and milk products. Moreover, mice with a human-like defect showed no alternate pathway for Neu5Gc synthesis and even normal humans express anti-Neu5Gc antibodies. We show here that human tumors accumulate Neu5Gc that is covalently attached to multiple classes of glycans. The paradox of human tumor Neu5Gc accumulation in the face of circulating anti-Neu5Gc antibodies was hypothesized to be due to facilitation of tumor progression by the resulting low-grade chronic inflammation. Indeed, murine tumors expressing human-like levels of Neu5Gc show accelerated growth in syngeneic mice with a human-like Neu5Gc deficiency, coincident with the induction of anti-Neu5Gc antibodies and increased infiltration of inflammatory cells. Transfer of polyclonal monospecific syngeneic mouse anti-Neu5Gc serum also enhanced growth of transplanted syngeneic tumors bearing human-like levels of Neu5Gc, with tumors showing evidence for antibody deposition, enhanced angiogenesis and chronic inflammation. These effects were suppressed by a cyclooxygenase-2 inhibitor, a drug type known to reduce human carcinoma risk. Finally, affinity-purified human anti-Neu5Gc antibodies also accelerate growth of Neu5Gc-containing tumors in Neu5Gc-deficient mice. Taken together, the data suggest that the human propensity to develop diet-related carcinomas is contributed to by local chronic inflammation, resulting from interaction of metabolically-accumulated dietary Neu5Gc with circulating anti-Neu5Gc antibodies.", "title": "Evidence for a human-specific mechanism for diet and antibody-mediated inflammation in carcinoma progression" }, { "docid": "MED-3153", "text": "This was a placebo-controlled, double-blind study designed to evaluate the effect of a commercially available dietary supplement on upper-respiratory tract symptoms (URTI) and mood state.

MATERIAL AND METHODS: A 6-month, double-blind, placebo-controlled, randomized, partial crossover, comparative trial of Urtica dioica with placebo in 620 patients was conducted. Patients were evaluated using the International Prostate Symptom Score (IPSS), the maximum urinary flow rate (Qmax), postvoid residual urine volume (PVR), Serum Prostatic- Specific Antigen (PSA), testosterone levels, and prostate size. At the end of 6-month trial, unblinding revealed that patients who initially received the placebo were switched to Urtica dioica. Both groups continued the medication up to 18 months. RESULTS: 558 patients (90%) completed the study (287/305, 91% in the Urtica dioica group, and 271/315, 86% in the placebo group). By intention- to-treat analysis, at the end of 6-month trial, 232 (81%) of 287 patients in the Urtica dioica group reported improved LUTS compared with 43 (16%) of 271 patients in the placebo group (P < 0.001).

Humans are commonly exposed to viruses that naturally infect and cause cancer in food animals such as poultry that constitute part of the biological environment. It is not known if these viruses cause cancer in humans. OBJECTIVE: To study cancer mortality in the largest cohort to date, of 20,132 workers in poultry slaughtering and processing plants, a group with the highest human exposures to these viruses. METHODS: Mortality in poultry workers was compared with that in the US general population through the estimation of standardized mortality ratios. RESULTS: Significantly increased risks were observed in the cohort as a whole or in subgroups, for several cancer sites, viz: cancers of the buccal cavity and pharynx; pancreas; trachea/bronchus/lung; brain; cervix; lymphoid leukemia; monocytic leukemia; and tumors of the hemopoietic and lymphatic systems. Elevated SMRs that were not statistically significant were observed for cancers of the liver, nasopharynx, myelofibrosis, and myeloma. New sites observed to be significantly in excess in this study were cancers of the cervix and penis. CONCLUSION: This large study provides evidence that a human group with high exposure to poultry oncogenic viruses has increased risk of dying from several cancers. Other occupational carcinogenic exposures could be of importance in explaining some of the findings, such as fumes from wrapping machines. These findings may have implications for public health amongst persons in the general population who may also be exposed to these viruses. What is needed now are epidemiologic studies that can demonstrate whether the excess of specific cancers can be attributed to specific occupational exposures while adequately controlling for other potential occupational and non-occupational carcinogenic exposures.

The relative juxtaposition of the hydrophobic amino-terminal region and the opening to the catalytic cleft shows why membrane anchoring is necessary for the lipophilic substrates to gain access to the active site.

Because naive T cells produce only IL-2 in short term culture, IFN-gamma production by this approach is a measure of a memory immune response. Stimulation of human PBLs or purified T lymphocytes with stimulator cells from inbred swine revealed a high frequency of IFN-gamma producers with 5-fold fewer IL-2 producers. In contrast, lymphocytes obtained from neonatal umbilical cord blood contained swine-specific IL-2 producers but few IFN-gamma producers, which is what one would expect to find with a naive phenotype. Moreover, PBLs from adults with a history of abstention from pork consumption responded to swine cells with a significantly lower frequency of IFN-gamma producers than PBLs from adults with unrestricted diets did, suggesting that pork consumption may result in priming of swine-specific T cell immunity. Our findings provide the first evidence for naturally occurring xenospecific T cell immunity in humans.

We aimed to describe the pathogenic and immunological characteristics of this illness. METHODS: All patients from two abattoirs who presented or were referred to the Mayo Clinic (Rochester, MN, USA) with neurological symptoms were included. We recorded details of exposure to aerosolised brain tissue and did comprehensive neurological, laboratory, neuroimaging, electrophysiological, pathological, and autoimmune serological assessments. Healthy controls were recruited from the community and from workers at the plant in Minnesota. FINDINGS: 24 patients were identified (21 from Minnesota, three from Indiana). The shortest duration from first exposure to symptom onset was 4 weeks. No infectious agent that could trigger disease was identified. All patients developed polyradiculoneuropathy, which was usually sensory predominant and painful. Two patients had initial CNS manifestations: transverse myelitis and meningoencephalitis. Nerve conduction studies localised abnormalities to the most proximal and distal nerve segments. Quantitative sensory and autonomic testing revealed involvement of large and small sensory fibres and sweat fibres. MRI showed prominent abnormalities of roots and ganglia. Nerve biopsies identified mild demyelination, axonal degeneration, and perivascular inflammation. Protein concentrations were high in the CSF of 18 (86%) of 21 patients. Sera from all patients and 29 (34%) of 85 unaffected workplace controls (but none of 178 community controls) had a distinctive neural-reactive IgG; 75% of patients' sera contained an IgG specific to myelin basic protein. Seropositivity correlated directly with exposure risk in patients and controls. 17 patients required immunomodulatory therapies, six improved spontaneously, and one was lost to follow-up after exposure stopped. INTERPRETATION: The neurological disorder described is autoimmune in origin and is related to occupational exposure to multiple aerosolised porcine brain tissue antigens. The pattern of nerve involvement suggests vulnerability of nerve roots and terminals where the blood-nerve barrier is most permeable.

We recently found that ALSV antibody levels were associated with job tasks in the poultry industry. The objectives of this study are to examine whether a similar association can be found with REV antibody levels and to examine the correlation between REV and ALSV antibody levels. METHODS: Relative risk was estimated comparing REV antibody levels of 45 poultry workers with those of 44 controls. The expected mean antibody level was predicted for the association with employment by a generalized linear model. Correlation coefficient was measured between ALSV and REV antibody levels. RESULTS: REV antibody levels were significantly higher in poultry workers than in control subjects and were associated with gender and employment conditions, especially employment duration. The relative risk was significantly higher for some job categories. A significant correlation was observed between REV and ALSV antibody levels, which was strong among poultry workers, but weak among the control subjects. CONCLUSION: Antibody levels can be validly used to identify certain job tasks associated with high risk of exposure to REV in the workplace, and the practical implication is recommendations for protection at these job tasks. Importantly, in situations where there is exposure to multiple pathogens in the workplace, the analysis of antibody levels of one pathogen may sufficiently represent exposure to the other correlated pathogens.

Methods We conducted a case-crossover study to examine associations of a set of putative risk factors with recurrent gout attacks. Individuals with gout were prospectively recruited and followed online for one year. Participants were asked about the following information when experiencing a gout attack: the onset date of the gout attack, symptoms and signs, medications (including anti-gout medications), and potential risk factors (including daily intake of cherries and cherry extract) during the 2-day period prior to the gout attack. We assessed the same exposure information over 2-day control periods. We estimated the risk of recurrent gout attacks related to cherry intake using conditional logistic regression. Results Our study included 633 individuals with gout. Cherry intake over a 2-day period was associated with a 35% lower risk of gout attacks compared with no intake (multivariate odds ratio [OR] = 0.65, 95% CI: 0.50-0.85). Cherry extract intake showed a similar inverse association (multivariate OR=0.55, 95% CI: 0.30-0.98). The effect of cherry intake persisted across subgroups by sex, obesity status, purine intake, alcohol use, diuretic use, and use of anti-gout medications. When cherry intake was combined with allopurinol use, the risk of gout attacks was 75% lower than periods without either exposure (OR=0.25, 95% CI: 0.15-0.42).

The aim of this review was to assess the clinical evidence for or against the effectiveness of the maca plant as a treatment for sexual dysfunction. Methods We searched 17 databases from their inception to April 2010 and included all randomised clinical trials (RCTs) of any type of maca compared to a placebo for the treatment of healthy people or human patients with sexual dysfunction. The risk of bias for each study was assessed using Cochrane criteria, and statistical pooling of data was performed where possible. The selection of studies, data extraction, and validations were performed independently by two authors. Discrepancies were resolved through discussion by the two authors. Results Four RCTs met all the inclusion criteria. Two RCTs suggested a significant positive effect of maca on sexual dysfunction or sexual desire in healthy menopausal women or healthy adult men, respectively, while the other RCT failed to show any effects in healthy cyclists. The further RCT assessed the effects of maca in patients with erectile dysfunction using the International Index of Erectile Dysfunction-5 and showed significant effects.

The aim of the present article is to describe the most important historical and cultural aspects of nut consumption throughout history. DATA SYNTHESIS: We discuss the following historical aspects of nuts originating in the Mediterranean: prehistory, the Egyptian civilization, their spread through the Mediterranean region by the Greek, Phoenician and Roman civilizations, and their reintroduction into Europe by means of the Al-Andalus culture. Particular emphasis is placed on the healthy and nutritional attributes that nuts have had throughout history. We also consider the role of the first globalization of food--the exchange of nuts between continents--and discuss the symbolism that nuts have had for humans throughout history in the context of cultural aspects of the Mediterranean region. CONCLUSIONS: Nuts and fruits are probably the earliest foods consumed by humans and are considered to be important because of their nutritional properties.

In an era of increasing use of supplements to better life, the benefits of DHEA in the aging female population are controversial. The goal of this article is to critically review published studies to determine if there is a role for DHEA supplementation in postmenopausal women. RECENT FINDINGS: Daily administration of oral DHEA achieves serum concentrations similar to those of women in their 20s. Several observational studies have shown that lower DHEA levels are associated with increased cardiovascular risk in women; however, interventional trials show no improvement in atherosclerosis or cardiovascular risk factors, and a lowering of HDL cholesterol levels. DHEA supplementation modestly increases bone mineral density in conjunction with adjuvant therapies and improves cognition in those with mild-to-moderate cognitive impairment, but does not affect cognition in unimpaired women. Use of intravaginal DHEA, but not oral DHEA, alleviates vaginal atrophy and improves sexual function in postmenopausal women.

Dietary lignans are metabolized to enterolignans, which are subsequently absorbed and become bioavailable. PATIENTS AND METHODS: We assessed the prognosis of 1,140 postmenopausal patients with breast cancer age 50 to 74 years who were diagnosed between 2002 and 2005. Vital status through the end of 2009 was ascertained via local population registries, and deaths were verified by death certificates. Information on recurrences and secondary tumors was verified by clinical records and attending physicians. Associations of postdiagnostic serum enterolactone (a biomarker for dietary lignans) with overall survival and distant disease-free survival were assessed by using Cox proportional hazards models stratified by age at diagnosis and adjusted for prognostic factors. RESULTS: Median enterolactone levels for deceased patients and those still alive were 17.0 and 21.4 nmol/L, respectively. During a median of 6.1 years of follow-up after diagnosis, 162 deaths were confirmed. Higher serum enterolactone levels were associated with significantly reduced hazard ratios (HRs) for death (HR per 10 nmol/L increment, 0.94; P = .04; HR for the highest quartile, 0.58; 95% CI, 0.34 to 0.99).

You would do best to borrow as much as you possibly can, treating it as a grant. Case 2 - you make 100K after graduation. You pay back over 7K a year. If you borrowed the full 51, after 7 or 8 years it would be paid off (yeah, yeah, inflation, interest, but maybe that might make it 9 years.)

Invest your sponsorships and savings into something long term since you know you won't be needing to draw on them. Case 3 - you make 30K after graduation. Here, the payments you have to make actually impact how much disposable income you have. You pay back 810 a year, and over 30 years that's about 25K of principal. It will be less if you account for some (even most) of the payment going to interest, not principal. Anything you borrow above 25K (or the lower, more accurate amount) is \"\"free\"\". If you borrow substantially less than that (by using your sponsorship, savings, and summer job) you may be able to stop paying sooner than 30 years.

Running slightly more realistic versions of these calculations where your salary goes up, and you take interest into account, I think you will discover, for each possible salary path, a number that represents how much of your loan is really loan: everything above that is actually a grant you do not pay back. The less you are likely to make, the more of it is really grant. On top of that, it seems to me that no matter the loan/grant ratio, \"\"borrow as much as you can from this rather bizarre source\"\" appears to be the correct answer.

Having said all that, I don't recommend borrowing money to buy a car, especially if you have that amount of cash set aside for the car. Here are some of the reasons: Sometimes people feel better about spending large amounts of money if they can pay it off over time, rather than spending it all at once. They tell themselves that they will come out ahead with their investments, or they will be earning more later, or some other story to make themselves feel better about overspending.

By not spending the money you will earn $332,194 over the course of 30 years. So if you can invest at 5% and borrow at 2% you will end up with $283,532 more than if you didn't.

Also, they didn't mean \"\"make money from thin air\"\" in the sense of it being a magical trick. They make money from a sort of market inefficiency: they broker between people who want to invest money and those who want to borrow it. The top two answers are about right: a bank borrows money from investors (who deposit money in checking and savings accounts), and lends it to borrowers in the form of loans or mortgages. The difference between the interest rates is their profit. You deposit $1000 with me at 2% for 20 years. I give you $1485.95 at the end of that term. Where did I get the extra five hundred books? Well I lent it out in mortgages over the same terms at 6% and received $3207.14 over the same period of time. Your $1000 made you $485.95, and made me $1721.19 which I keep for the purposes of providing you with ATMs, dealing with bad debts and staffing the place. Simple, eh? Of course, they also provide other services in addition to this, and the way in which they do it is regulated, but that's all a bank is at its core. A central bank is slightly different: they issue money (i.e. \"\"print\"\" it), and supply it at a headline interest rate to the commercial banks. And of course banks borrow amongst themselves. But then we get ourselves down the rabbit hole of \"\"grown up\"\" economics and LIBOR and the like... there are whole textbooks used to explain exactly how that mechanism works and what's going on there.

I'll start with the high level fundamentals and work my way down to the specific question that I had. So point #5 is really the starting point for my answer. We want to find companies that are investing their money. A good company should be reinvesting most of its excess assets so that it can make more money off of them. If a company has too much working capital, then it is not being efficiently reinvested. That explains why excess working capital can have a negative impact on Return on Capital. But what about the fact that current liabilities in excess of current assets has a positive impact on the Return on Capital calculation? That is a problem, period. If current liabilities exceed current assets then the company may have a hard time meeting their short term financial obligations. This could mean borrowing more money, or it could mean something worse - like bankruptcy. If the company borrows money, then it will have to repay it in the future at higher costs. This approach could be fine if the company can invest money at a rate of return exceeding the cost of their debt, but to favor debt in the Return on Capital calculation is wrong. That scenario would skew the metric. The company has to overcome this debt. Anyways, this is my understanding, as the amateur investor. My credibility is not even comparable to Greenblatt's credibility, so I have no business calling any part of his calculation wrong.

So, in general lower interest rates will make the share market a more attractive investment (than some alternatives) as investors are willing to take on more risk for potentially higher returns. This will usually result in the stock market rising as it is currently in the US. EDIT: The case for rising interest rates A central bank's purpose when raising interest rates is to slow down an economy that is booming. As interest rates rise consumers will tighten up their spending and companies will thus have less revenue on top of higher costs for maintaining existing borrowing (with variable rates) or new borrowing (with fixed rates). If rates are higher companies may also defer new borrowings to expand their business. This will eventually lead to lower profits and lower valuation for these companies. Another thing that happens is that as banks start increasing interest for saving accounts investors will look for safety where they can get a higher return (than before) without the risk of the stock market. With lowering profits and valuations, and investor's money flowing out of shares and into the money market, so will company share prices drop (although this may lag a bit with the share market still booming due to greed.

Unless you have a really creative tax accountant or live in a country with very unusual tax laws, any tax deduction you get for mortgage interest is going to be less than the interest. You don't come out ahead by getting a $25 deduction if you had a $100 expense to get that deduction. Where there can be some sense behind such a statement is if you consider the alternative to paying cash for a house or making extra payments against a mortgage. If you had $100,000 in cash in a box under your bed, and the choice is between, (a) use that $100,000 to buy a house in cash, or (b) borrow $100,000 at 6% interest and leave that cash in the box under the bed, than clearly (a) is the better choice because it saves you the interest expense. But if the choice is between, (a) buy a house for $100,000 in cash and borrow $100,000 at 6% to buy a car; or (b) borrow $100,000 at 6% interest to buy a house and use the $100,000 cash to buy the car, (b) is the better choice. The home mortgage loan is tax deductible; the car loan is not. As others have pointed out, if instead of using some extra cash to pay down the principle on your mortgage you used that money to invest in the stock market, it is likely that you would get better returns on the investment than what you would have saved in interest on the mortgage -- depending, of course, on how the market is doing and how well you pick stocks. But the key issue there isn't the tax deduction, it's the comparison of the profits from the investment versus the opportunity cost of the money that could have been saved on the mortgage interest. The tax deduction affects that comparison by effectively reducing the interest rate on the mortgage -- your real interest expense is the nominal interest minus the deduction -- but that's not the key point, just another number to plug in to the formula. By the way, given the complexity of U.S. tax law, I would not rule out the possibility that there could be some scenario where you really would save money by having mortgage interest. There are lots of deductions and credits that are phased out or eliminated as your income goes up. Perhaps you could find some set of tax laws that apply to you such that having an additional $1000 in interest expense lets you take a $300 deduction here and a $500 credit there, etc, and they add up to more than $1000.

Investing with borrowed money implies you think you can beat the market: that you're a cleverer investor than whoever decided to lend you the money. Whoever decided to lend you the money decided that you are the best (return/risk ratio) investment for their money. It might make sense to invest borrowed money if you don't need to pay it back if things go wrong: if you're an investment professional whose bonus depends on the profit you make, but who won't need to repay any loss. It might also makes sense to borrow money if you're going to 'add value', e.g. sweat equity: for example if you use it to renovate a house or (if you're a business) to hire more staff.

To do so, you need to convince a lender that you're good for the loan. This usually means you need to have collateral worth what you're trying to borrow, or you need to pay a higher rate to account for the fact that they're gambling that you will remain employed and pay off the loan. Leveraged investing is, in general, a risky move for exactly this reason. You can lose not just your original investment, but everything you borrowed as well. The only time it really makes sense, in my admittedly conservative opinion, is when you (a) can afford to suffer that loss, (b) are pretty confident of your investment, and (c) have assets which you have no intention to sell for the duration of the loan. An \"\"unneeded\"\" mortgage on a house is a classic example, thusly: When I purchased my house, I had enough savings that I could have bought it without taking a mortgage. Instead, I took out a mortgage for a large part of that, and left the remainder in my investment accounts -- essentially building the leveraging loan into the mortgage. I then got obscenely \"\"lucky\"\" when interest rates fell through the floor due to the Great Recession, and was able to refinance the mortgage to near record low rates. As a result, on that loan -- which, as I say, I'm in the position of being able to pay off at any time without killing my finances -- I'm currently paying about 3.5%, while the cash this has let me leave in my investments is earning several times that... a net win. But again, note that this required collateral. Essentially, all I'm doing is paying a bit to to borrow my own money (part of the value of the house). There really is no easy way to \"\"convert 25k to 250k\"\" -- if there was, everyone would be doing it. There's no magic in investment. Just time and compounding returns and trading off risk against potential gain. The more you try to push it and win big, the more you risk losing big. I really recommend not attempting anything fancy until you're wealthy enough that you can afford those losses. But if you insist on playing in this space, the answer to your question is to buy options. Options are a packaged form of borrowing to invest. Note that they're still considered high-risk unless you know EXACTLY what you're doing, and again I strongly recommend you not put money into them unless you can afford to lose it -- options have a nasty habit of turning from apparent gains on paper to losses remarkably quickly.\"", "title": "" }, { "docid": "505172", "text": "The answer is mathematics.

A property now requires 8% growth for $25 profit in a year, where a unit trust now requires 29% growth for $25 profit. Which one is more likely?

Company finance is generally a balance between borrowing, and money raised from shares. It should be self evident with a little thought that if not now, then in the future, a company should be able to create earnings in excess of the cost of borrowing, or it's not a very valuable company to invest in! In fact what's the point of borrowing if the cost of the interest is greater than whatever wealth is being generated? The important thing about this is that money raised from shares is more expensive than borrowing. If a company doesn't pay dividends, and its share price goes up because of the increasing value of the business, and in your example the company is not borrowing more because of this, then the proportion of the value of the company that is based on the borrowing goes down. So, this means a higher and higher proportion of the finance of a company is provided by the more expensive share holders than the less expensive borrowing, and thus the company is actually providing LESS value to share holders than it might. Of course, if a company doesn't pay a dividend AND borrows more, this is not true, but that's not the scenario in your question, and generally mature companies with mature earnings may as well pay dividends as they aren't on a massive expansion drive in the same way. Now, this relative expense of share holders and borrowing is MORE true for a mature company with stable earnings, as they are less of a risk and can borrow at more favourable rates, AND such a company is LIKELY to be expanding less rapidly than a small new innovative company, so for both these reasons returning money to share holders and borrowing (or maintaining existing lending facilities) maintains a relatively more efficient financing ratio. Of course all this means that in theory, a company should be more efficient if it has no share holders at all and borrows ALL of the money it needs. Yes. In practise though, lenders aren't so keen on that scenario, they would rather have shareholders sharing the risk, and lending a less than 100% proportion of the total of a companies finance means they are much more likely to get their money back if things go horribly wrong. To take a small start up company by comparison, lenders will be leary of lending at all, and will certainly impose high rates if they do, or ask for guarantors, or demand security (and security is only available if there is other investment besides the loan). So this is why a small start up is likely to be much more heavily or exclusively funded by share holders. Also the start up is likely not to pay a dividend, because for a start it's probably not making any profit, but even if it is and could pay a dividend, in this situation borrowing is unavailable or very expensive and this is a rapidly growing business that wants to keep its hands on all the cash it can to accelerate itself. Once it starts making money of course a start up is on its way to making the transition, it becomes able to borrow money at sensible rates, it becomes bigger and more valuable on the back of the borrowing. Another important point is that dividend income is more stable, at least for the mature companies with stable earnings of your scenario, and investors like stability. If all the income from a portfolio has to be generated by sales, what happens when there is a market crash? Suddenly the investor has to pay, where as with dividends, the company pays, at least for a while. If a company's earnings are hit by market conditions of course it's likely the dividend will eventually be cut, but short term volatility should be largely eliminated.", "title": "" }, { "docid": "441518", "text": "\"A good question -- there are many good tactical points in other answers but I wanted to emphasize two strategic points to think about in your \"\"5-year plan\"\", both of which involve around diversification: Expense allocation: You have several potential expenses.

For example, your car has been towed and they need cash. A short-term cushion for emergencies -- something bad happens and you need the money in a few days or weeks.

A long-term savings cushion -- you might want to make a down payment on a house or a car, but you know it's some years off.

Are you planning on getting a job with a dependable salary, or do you plan on being self-employed, where there is more uncertainty in your income? These are all factors that will help you decide how important short-term and long term savings are to your 5-year plan. In short, there is no one place you should put your money.

It was very easy to get attracted to the high risk loans with big interest rates and I lost about 14% after all my loans ran their course. (There's 10 still active, but it won't change the figure by much). Prosper has wider standards than Lending club, so more borrowers with worse credit scores could ask for loans. Lenders could also set interest rates far lower, so they could end up having loans with rates lower than the risk implied. This was set up with the idea of a free market where anyone could ask to borrow and anyone could loan money at whatever interest rate they wanted, It turns out a lot of lenders were not as smart as they thought they were. (Aside: it's funny how people will clamor for a free market, but when they lose money will suddenly be against the free market they said they wanted, this seems to apply to both individual p2p lenders up to massive multinational banks.). Since then Prosper has tightened their standards on who can borrow and the interest rates are now fixed. So I expect going forward it will be less easy to lose a bunch of money. The key is that one bad loan will erase the return of many good ones. So it's best to examine the loans carefully and stick with the high quality. Simplified Example If you have 10 1 yr loans of $100 each paying 10% interest/year, you get 10% return at the end of the year, so $100 (10% of $1000.). BUT if one loan goes bad at the start, you have lost money. So a 90% success rate in picking borrowers leads to a loss. You want to diversity over quite a few loans and you want to fund quality loans.

It's because they're compounded daily, and the product of all the doubled daily returns is not mathematically equivalent to the double the long-term return. I'd consider providing big fancy equations using uppercase pi as the 'product of elements in a sequence' operator and other calculus fanciness, but that would be overkill, I don't think I can do TeX here, and I don't know the relevant TeX anyway. Anyway. From the economics theory perspective, the ideal leverage ratio is 1X - that is, unlevered, straight investment. Consider: Using leverage costs money. You know that, surely. If someone could borrow money at N% and invest at an expected N+X%, where X > 0, then they would. They would borrow all the money they could and buy all the S&P500 they could. But when they bought all that S&P500, they'd eventually run out of people who were willing to sell it for that cheap. That would mean the excess return would be smaller. Eventually you'd get to a point where the excess return is... zero? .... well, no, empirically, we can see that it's definitely not zero, and that in the real world that stocks do return more than bonds. Why? Because stocks are riskier than bonds. The difference in expected return between an index like the S&P500 and a US Treasury bond is due to the relative riskiness of the S&P500, which isn't guaranteed by the US Government to return your principal. Any money that you make off of leverage comes from assuming some sort of a risk. Now, assuming risk can be a profitable thing to do, but there are also a lot of people out there with higher risk tolerance than you, like insurance companies and billionaires, so the market isn't exactly short of people willing to take risks, and you shouldn't expect the returns of \"\"assuming risk\"\" in the general case to be qualitatively awesome. Now, it's true that investing in an unlevered fashion is risky also. But that's not an excuse to go leveraged anyway; it's a reason to hold back. In fact, regular stocks are sufficiently risky that most people probably shouldn't be holding a 100% stock portfolio. They should be tempering that risk with bonds, instead, and increasing the size of their bond holdings over time. The appropriate time to use leverage is when you have information which limits your risk. You have done research, and have reason to believe that you understand the future of an individual stock/index better than the rest of the stock market does. You calculate that the potential for achieving returns with leverage outweighs the risks. Then you dump your money into the leveraged position. (In exchange for this, the market receives information about anticipated future returns of this instrument, because of the price movement which occurs as a result of someone putting his money where his mouth is.) If you're just looking to dump money into broad market indicies in a leveraged fashion, you're doing it wrong. There is no free money. (Ed. Which is not to say there's not money. There's lots of money. But if you go looking for the free kind, you won't find it, and may end up with money that you thought was free but was actually quite expensive.) Edit. Okay, so you don't like my answer. I'm not surprised. I'm giving you a real answer instead of a \"\"make free money\"\" answer. Okay. Here's your \"\"how to make free money\"\" answer. Assume you are using a constant leverage ratio over the length of time you've invested your money, and you don't get to just jump into and out of the market (that's market-timing, not leverage) so you have to stay invested. You're going to have a scenario which falls into one of these categories: The S&P500 historically rises over time. The average rate of return probably exceeds the average interest rate. So the ideal leverage ratio is infinite. Of course, this is a stupid answer in real life because you can't pull that off. Your risk tolerance is too low and you will have trouble finding a lender willing to lend you unsecured money, and you'll probably lose all your money in a crash sooner or later. Ultimately it's a stupid answer because you're asking the wrong question. You should probably ask a better question: \"\"when I use leverage to gain additional exposure to risk, am I being properly compensated for assuming that risk?\"\"\"", "title": "" }, { "docid": "329930", "text": "\"I would undoubtedly sell the investments if they are positive, maybe even a little negative.

Patients with microcytosis and higher erythrocyte count were more resistant to severe malarial anaemia when infected with Plasmodium falciparum.
[ { "docid": "18174210", "text": "BACKGROUND The heritable haemoglobinopathy alpha(+)-thalassaemia is caused by the reduced synthesis of alpha-globin chains that form part of normal adult haemoglobin (Hb). Individuals homozygous for alpha(+)-thalassaemia have microcytosis and an increased erythrocyte count. Alpha(+)-thalassaemia homozygosity confers considerable protection against severe malaria, including severe malarial anaemia (SMA) (Hb concentration < 50 g/l), but does not influence parasite count. We tested the hypothesis that the erythrocyte indices associated with alpha(+)-thalassaemia homozygosity provide a haematological benefit during acute malaria. METHODS AND FINDINGS Data from children living on the north coast of Papua New Guinea who had participated in a case-control study of the protection afforded by alpha(+)-thalassaemia against severe malaria were reanalysed to assess the genotype-specific reduction in erythrocyte count and Hb levels associated with acute malarial disease. We observed a reduction in median erythrocyte count of approximately 1.5 x 10(12)/l in all children with acute falciparum malaria relative to values in community children (p < 0.001). We developed a simple mathematical model of the linear relationship between Hb concentration and erythrocyte count. This model predicted that children homozygous for alpha(+)-thalassaemia lose less Hb than children of normal genotype for a reduction in erythrocyte count of >1.1 x 10(12)/l as a result of the reduced mean cell Hb in homozygous alpha(+)-thalassaemia. In addition, children homozygous for alpha(+)-thalassaemia require a 10% greater reduction in erythrocyte count than children of normal genotype (p = 0.02) for Hb concentration to fall to 50 g/l, the cutoff for SMA. We estimated that the haematological profile in children homozygous for alpha(+)-thalassaemia reduces the risk of SMA during acute malaria compared to children of normal genotype (relative risk 0.52; 95% confidence interval [CI] 0.24-1.12, p = 0.09). CONCLUSIONS The increased erythrocyte count and microcytosis in children homozygous for alpha(+)-thalassaemia may contribute substantially to their protection against SMA. A lower concentration of Hb per erythrocyte and a larger population of erythrocytes may be a biologically advantageous strategy against the significant reduction in erythrocyte count that occurs during acute infection with the malaria parasite Plasmodium falciparum. This haematological profile may reduce the risk of anaemia by other Plasmodium species, as well as other causes of anaemia. Other host polymorphisms that induce an increased erythrocyte count and microcytosis may confer a similar advantage.", "title": "Increased Microerythrocyte Count in Homozygous α+-Thalassaemia Contributes to Protection against Severe Malarial Anaemia" } ]

The molecular basis of this resistance, which has long been recognized as multifactorial, remains incompletely understood. Here we show that the dysregulated microRNA (miRNA) composition, of either heterozygous HbAS or homozygous HbSS erythrocytes, contributes to resistance against P. falciparum. During the intraerythrocytic life cycle of P. falciparum, a subset of erythrocyte miRNAs translocate into the parasite. Two miRNAs, miR-451 and let-7i, were highly enriched in HbAS and HbSS erythrocytes, and these miRNAs, along with miR-223, negatively regulated parasite growth. Surprisingly, we found that miR-451 and let-7i integrated into essential parasite messenger RNAs and, via impaired ribosomal loading, resulted in translational inhibition.

Statistical analysis was done using SAS 9.1. RESULTS Six hundred and ninety five children with acute uncomplicated malaria participated in the study. The mean age was 51.7 months +/- 33.8. At presentation, anaemia occurred in 43.8% of the patients and children <5 yr had a significantly lower haematocrit (28.4% +/- 4.8) than that of older children (32.8% +/- 4.8) (p <0.001), but the haematocrit was not significantly different by days 14 and 28.

Children with malaria had a higher WCC compared with community controls, and leucocytosis was strongly associated with younger age, deep breathing, severe anaemia, thrombocytopenia and death. The WCC was not associated with a positive blood culture. In children with malaria, high lymphocyte and low monocyte counts were independently associated with mortality.

A recent field study in an area of low seasonal transmission in South West Cambodia demonstrated dramatic reductions in malaria parasite prevalence following both mass drug administration (MDA) and high treatment coverage of symptomatic patients with artemisinin-piperaquine plus primaquine. This study employed multiple combined strategies and it was unclear what contribution each made to the reductions in malaria. METHOD AND FINDINGS A mathematical model fitted to the trial results was used to assess the effects of the various components of these interventions, design optimal elimination strategies, and explore their interactions with artemisinin resistance, which has recently been discovered in Western Cambodia. The modelling indicated that most of the initial reduction of P. falciparum malaria resulted from MDA with artemisinin-piperaquine. The subsequent continued decline and near elimination resulted mainly from high coverage with artemisinin-piperaquine treatment. Both these strategies were more effective with the addition of primaquine. MDA with artemisinin combination therapy (ACT) increased the proportion of artemisinin resistant infections, although much less than treatment of symptomatic cases with ACT, and this increase was slowed by adding primaquine. Artemisinin resistance reduced the effectiveness of interventions using ACT when the prevalence of resistance was very high. The main results were robust to assumptions about primaquine action, and immunity. CONCLUSIONS The key messages of these modelling results for policy makers were: high coverage with ACT treatment can produce a long-term reduction in malaria whereas the impact of MDA is generally only short-term; primaquine enhances the effect of ACT in eliminating malaria and reduces the increase in proportion of artemisinin resistant infections; parasite prevalence is a better surveillance measure for elimination programmes than numbers of symptomatic cases; combinations of interventions are most effective and sustained efforts are crucial for successful elimination.", "title": "Optimising Strategies for Plasmodium falciparum Malaria Elimination in Cambodia: Primaquine, Mass Drug Administration and Artemisinin Resistance" }, { "docid": "13959707", "text": "BACKGROUND Plasmodium falciparum malaria remains a major cause of illness and death in sub-Saharan Africa.

This study estimates the reduction in transmission that may be achieved by introducing different types of treatment for symptomatic P. falciparum malaria in endemic areas. METHODS AND FINDINGS We developed a mathematical model to predict the potential impact on transmission outcomes of introducing ACT as first-line treatment for uncomplicated malaria in six areas of varying transmission intensity in Tanzania. We also estimated the impact that could be achieved by antimalarials with different efficacy, prophylactic time, and gametocytocidal effects. Rates of treatment, asymptomatic infection, and symptomatic infection in the six study areas were estimated using the model together with data from a cross-sectional survey of 5,667 individuals conducted prior to policy change from sulfadoxine-pyrimethamine to ACT. The effects of ACT and other drug types on gametocytaemia and infectiousness to mosquitoes were independently estimated from clinical trial data. Predicted percentage reductions in prevalence of infection and incidence of clinical episodes achieved by ACT were highest in the areas with low initial transmission. A 53% reduction in prevalence of infection was seen if 100% of current treatment was switched to ACT in the area where baseline slide-prevalence of parasitaemia was lowest (3.7%), compared to an 11% reduction in the highest-transmission setting (baseline slide prevalence = 57.1%). Estimated percentage reductions in incidence of clinical episodes were similar. The absolute size of the public health impact, however, was greater in the highest-transmission area, with 54 clinical episodes per 100 persons per year averted compared to five per 100 persons per year in the lowest-transmission area. High coverage was important. Reducing presumptive treatment through improved diagnosis substantially reduced the number of treatment courses required per clinical episode averted in the lower-transmission settings although there was some loss of overall impact on transmission. An efficacious antimalarial regimen with no specific gametocytocidal properties but a long prophylactic time was estimated to be more effective at reducing transmission than a short-acting ACT in the highest-transmission setting.

Less documented is how this translates into chemical stability and antimalarial activity across a range of conditions applying to in vitro testing and clinical situations. Dihydroartemisinin (DHA) is studied here because it is an antimalarial drug on its own and the main metabolite of other artemisinins. The behaviors of DHA in phosphate-buffered saline, plasma, or erythrocyte lysate at different temperatures and pH ranges were examined. The antimalarial activity of the residual drug was evaluated using the chemosensitivity assay on Plasmodium falciparum, and the extent of decomposition of DHA was established through use of high-performance liquid chromatography with electrochemical detection analysis. The role of the Fe(II)-heme was investigated by blocking its reactivity using carbon monoxide (CO). A significant reduction in the antimalarial activity of DHA was seen after incubation in plasma and to a lesser extent in erythrocyte lysate. Activity was reduced by half after 3 h and almost completely abolished after 24 h. Serum-enriched media also affected DHA activity. Effects were temperature and pH dependent and paralleled the increased rate of decomposition of DHA from pH 7 upwards and in plasma.

The size of this effect is estimated in symptomatic P. falciparum infections. METHODS Data on 3,174 patients were pooled from six antimalarial trials conducted in The Gambia and Kenya. Multivariable regression was used to investigate the role of ACT versus non-artemisinin antimalarial treatment, treatment failure, presence of pre-treatment gametocytes and submicroscopic gametocytaemia on transmission to mosquitoes and the area under the curve (AUC) of gametocyte density during the 28 days of follow up. RESULTS ACT treatment was associated with a significant reduction in the probability of being gametocytaemic on the day of transmission experiments (OR 0.20 95% CI 0.16-0.26), transmission to mosquitoes by slide-positive gametocyte carriers (OR mosquito infection 0.49 95% CI 0.33-0.73) and AUC of gametocyte density (ratio of means 0.35 95% CI 0.31-0.41). Parasitological treatment failure did not account for the difference between ACT and non-artemisinin impact. The presence of slide-positive gametocytaemia prior to treatment significantly reduced ACT impact on gametocytaemia (p < 0.001). Taking account of submicroscopic gametocytaemia reduced estimates of ACT impact in a high transmission setting in Kenya, but not in a lower transmission setting in the Gambia. CONCLUSION Treatment with ACT significantly reduces infectiousness of individual patients with uncomplicated falciparum malaria compared to previous first line treatments.

Indeed, Plasmodium falciparum contains at least two mdr-like genes7,8, one of which has been suggested to confer the chloroquine resistant (CQR) phenotype7,9,10. To determine if either of these genes is linked to chloroquine resistance, we performed a genetic cross between CQR and chloroquine-susceptible (CQS) clones of P. falciparum. Examination of 16 independent recombinant progeny indicated that the rapid efflux phenotype is controlled by a single gene or a closely linked group of genes. But, there was no linkage between the rapid efflux, CQR phenotype and either of the mdr-like P. falciparum genes or amplification of those genes.

Methods. Kenyan children (n=528) 6 months-10 years of age were randomized to 4 treatment arms. Gametocytemia was determined by both microscopy and Pfs25 RNA-based quantitative nucleic acid sequence-based amplification (Pfs25 QT-NASBA). Transmission was determined by membrane-feeding assays. Results. Gametocyte prevalence, as determined by Pfs25 QT-NASBA, was 89.4% (219/245) at enrollment and decreased after treatment with SP plus AS, SP plus AQ, and AL. Membrane-feeding assays for a group of randomly selected children revealed that the proportion of infectious children was as much as 4-fold higher than expected when based on microscopy. ACT did not significantly reduce the proportion of infectious children but did reduce the proportion of infected mosquitoes. Conclusions. Submicroscopic gametocytemia is common after treatment and contributes considerably to mosquito infection.

RESULTS Severe hepatotoxicity was observed in 31 (10.4%) of 298 patients (95% confidence interval [CI], 7.2%-14.4%).

METHODS HIV-infected patients with newly diagnosed pulmonary or extrapulmonary TB were randomly assigned to Reg6M (n = 167) or Reg9M (n = 160) and monitored by determination of clinical, immunological, and bacteriological parameters for 36 months. Primary outcomes included favorable responses at the end of treatment and recurrences during follow-up, whereas the secondary outcome was death. Intent-to-treat and on-treatment analyses were performed. All patients were antiretroviral treatment-naive during treatment. MEASUREMENTS AND MAIN RESULTS Of the patients, 70% had culture-positive pulmonary TB; the median viral load was 155,000 copies/ml and the CD4(+) cell count was 160 cells/mm(3). Favorable response to antituberculosis treatment was similar by intent to treat (Reg6M, 83% and Reg9M, 76%; P = not significant). Bacteriological recurrences occurred significantly more often in Reg6M than in Reg9M (15 vs. 7%; P < 0.05) although overall recurrences were not significantly different (Reg6M, 19% vs. Reg9M, 13%).

An increasing body of research and the 2010 Dietary Guidelines for Americans supports the benefits of a plant-based diet, and legumes specifically, in the reduction of chronic disease risks. The purpose of the current research was to investigate the perception of increased flatulence and gastrointestinal discomfort among participants who consumed a ½ cup of beans daily for 8 or 12 weeks. Methods Participants in three studies to test the effects of beans on heart disease biomarkers completed the same weekly questionnaire to assess gastrointestinal discomfort issues such as increased flatulence, stool changes, and bloating. Studies 1 and 2 were randomized crossover trials. Participants consumed ½ cup of pinto beans, black-eyed peas, and canned carrots as control (n = 17) in Study 1 for three randomized 8-week phases. For Study 2, participants ate ½ cup baked beans or canned carrots as control (n = 29) for two randomized 8-week phases. Study 3 was a parallel arm trial with 40 subjects receiving ½ cup pinto beans and 40 consuming a control soup for 12 weeks. Changes in the frequency of perceived flatulence, stool characteristics, and bloating were the primary outcome measures. Chi-square distributions were examined for the presence or absence of symptoms and demographic characteristics to determine differences by gender, age, body mass index (BMI), and bean type. Results Less than 50% reported increased flatulence from eating pinto or baked beans during the first week of each trial, but only 19% had a flatulence increase with black-eyed peas. A small percentage (3-11%) reported increased flatulence across the three studies even on control diets without flatulence-producing components.

Samples consisted of the three or four top-selling products within the following six categories: natural cocoa powder, unsweetened baking chocolate, dark chocolate, semisweet baking chips, milk chocolate, and chocolate syrup. Composite samples were characterized for percent fat (% fat), percent nonfat cocoa solids (% NFCS), antioxidant level by ORAC, total polyphenols, epicatechin, catechin, total monomers, and flavan-3-ol oligomers and polymers (procyanidins). On a gram weight basis epicatechin and catechin content of the products follow in decreasing order: cocoa powder > baking chocolate > dark chocolate = baking chips > milk chocolate > chocolate syrup. Analysis of the monomer and oligomer profiles within product categories shows there are two types of profiles: (1) products that have high monomers with decreasing levels of oligomers and (2) products in which the level of dimers is equal to or greater than the monomers. Results show a strong correlation (R(2) = 0.834) of epicatechin to the level of % NFCS and also very good correlations for N = 2-5 oligomers to % NFCS. A weaker correlation was observed for catechin to % NFCS (R(2) = 0.680).

SETTING: Individual records were linked to the eventual death files from 2002 to 2008. SUBJECTS: Up to the end of 2008, a total of 2820 men and 2950 women were tracked by death registry over the 6·8 years of follow-up. RESULTS: Among 38,077 person-years, an average follow-up 6·5 years, 225 all-cause deaths were identified. Generalized linear models showed beans to be favourable for metabolic syndrome (other than for fasting glucose) in men; in women, beans were favourable for waist circumference and HbA1c. Cumulative logistic regression models for the effect of a bean-free diet on metabolic syndrome scores according to the Taiwanese-modified National Cholesterol Education Program-Adult Treatment Panel III (NCEP-tw) gave adjusted odds ratios of 1·83 in men and 1·45 in women. Cox regression models for the bean-free diet showed an increased hazard ratio for all-cause mortality among women (1·98, 95% CI 1·03, 3·81) but not men (1·28, 95% CI 0·76, 2·16).

METHODS: Randomized, crossover 3x3 block design. Sixteen participants (7 men, 9 women) received each treatment for eight-weeks with two-week washouts. Fasting blood samples collected at beginning and end of periods were analyzed for total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol, triacylglycerols, high-sensitivity C-reactive protein, insulin, glucose, and hemoglobin A1c. RESULTS: A significant treatment-by-time effect impacted serum TC (p = 0.026) and LDL (p = 0.033) after eight weeks.

Although relatively high levels of agaritine (around 700 mg kg(-1)) could be found in freshly harvested A. bitorquis from early flushes, samples from supermarkets contained less agaritine. The content of 28 samples varied between 165 and 457 mg kg(-1), on average being 272 +/- 69 mg kg(-1). The highest amounts of agaritine were found in the skin of the cap and in the gills, the lowest being in the stem. There was no significant difference in agaritine content of the two mushroom species in our study. Pronounced reduction in agaritine content was observed during storage of mushrooms in the refrigerator or freezer, as well as during drying of the mushrooms. The degree of reduction was dependent on the length and condition of storage and was usually in the region 20-75%. No reduction in agaritine content was observed during freeze-drying. Depending on the cooking procedure, household processing of cultivated Agaricus mushrooms reduced the agaritine content to various degrees. Boiling extracted around 50% of the agaritine content into the cooking broth within 5min and degraded 20-25% of the original agaritine content of the mushrooms. Prolonged boiling, as when preparing a sauce, reduced the content in the solid mushroom further (around 10% left after 2h). Dry baking of the cultivated mushroom, a process similar to pizza baking, reduced the agaritine content by approximately 25%, whereas frying in oil or butter or deep frying resulted in a more marked reduction (35-70%).

In some regions of the world, legume seeds are the only protein supply in the diet. The health benefits of legume consumption have received rising interest from researchers, and their consumption and production extends worldwide. Among European countries, higher legume consumption is observed around the Mediterranean, with per capita daily consumption between 8 and 23 g, while in Northern Europe, the daily consumption is less than 5 g per capita. The physiological effects of different legumes vary significantly. These differences may result from the polysaccharides composition, in particular, the quantity and variety of dietary fibers and starch, protein make-up, and variability in phytochemical content. The majority of legumes contain phytochemicals: bioactive compounds, including enzyme inhibitors, phytohemagglutinins (lectins), phytoestrogens, oligosaccharides, saponins, and phenolic compounds, which play metabolic roles in humans who frequently consume these foods.

Immediate and prolonged homeostatic effects of glucose ingestion have been well characterized. However, studies that used stimulation with fat have mainly investigated immediate perceptional processes. Besides homeostatic processes, the gustatory cortex, including parts of the insular cortex, is crucial for the processing of food items. OBJECTIVE: The aim of this study was to investigate the effect of high- compared with low-fat meals on the hypothalamus and the insular cortex. DESIGN: Eleven healthy men participated in a single-blinded, functional MRI study of high- and low-fat meals on 2 measurement days. Cerebral blood flow (CBF) was measured before and 30 and 120 min after intake of high- and low-fat yogurts. Hunger was rated and blood samples were taken before each CBF measurement. RESULTS: High-fat yogurt induced a pronounced decrease in CBF in the hypothalamus, and the corresponding CBF change correlated positively with the insulin change. Furthermore, insular activity increased after 120 min in the low-fat condition only. The CBF change in both regions correlated positively in the high-fat condition. CONCLUSIONS: The decrease in hypothalamic activity and the interaction with the insular cortex elicited by fat may contribute to an efficient energy homeostasis. Therefore, fat might be a modulator of homeostatic and gustatory brain regions and their interaction.

STUDY AND DESIGN: Randomized cross-over dietary intervention study. SUBJECTS: Forty-two free-living healthy males aged 35-62 y completed the dietary intervention. Three additional subjects were non-compliant and excluded prior to analysis. INTERVENTIONS: A diet containing lean meat (150 g/d) was compared with one with 290 g/d tofu in an isocaloric and isoprotein substitution. Both diet periods were 1 month, and fat intake was carefully controlled. RESULTS: Seven-day diet records showed the two diets were similar in energy, macronutrients and fibre. Total cholesterol (mean difference 0.23 mmol/l, 95% CI 0.02, 0.43; P=0.03) and triglycerides (mean difference 0.15 mmol/l, 95% CI 0.02, 0.31; P=0.017) were significantly lower on the tofu diet than the lean meat diet. However, HDL-C was also significantly lower on the tofu diet (mean difference 0.08 mmol/l, 95% CI 0.02, 0.14; P=0.01) although the LDL-C:HDL-C ratio was similar. CONCLUSION: The effect on HDL-C and the small LDL-C reduction differ from some other studies, where fat was often less controlled, and the comparison was of soy as textured protein or soymilk against casein. This suggests a differential effect of the various proteins compared to the soy may influence the findings. In practice, the replacement of meat with tofu would usually be associated with a decrease in saturated fat and an increase in polyunsaturated fat and this should enhance any small benefits due to the soy protein.

The objective was to compare the risk reductions achieved by different blood pressure-lowering regimens among individuals with different baseline blood pressures. METHODS: Thirty-two randomized controlled trials were included and seven comparisons between different types of treatments were made. For each comparison, the primary prespecified analysis included calculation of summary estimates of effect using random-effects meta-analysis for major cardiovascular events in four groups defined by baseline SBP (<140, 140-159, 160-179, and ≥ 180 mmHg). RESULTS: There were 201 566 participants among whom 20 079 primary outcome events were observed. There was no evidence of differences in the proportionate risk reductions achieved with different blood pressure-lowering regimens across groups defined according to higher or lower levels of baseline SBP (all P for trend > 0.17). This finding was broadly consistent for comparisons of different regimens, for DBP categories, and for commonly used blood pressure cut-points. CONCLUSION: It appears unlikely that the effectiveness of blood pressure-lowering treatments depends substantively upon starting blood pressure level. As the majority of patients in the trials contributing to these overviews had a history of hypertension or were receiving background blood pressure-lowering therapy, the findings suggest that additional blood pressure reduction in hypertensive patients meeting initial blood pressure targets will produce further benefits.

They are highly mutagenic towards Salmonella typhimurium in the presence of S9 mix and are also mutagenic in vitro and in vivo toward mammalian cells.

When HCAs were fed in the diet, rodents developed cancers in many organs, including the colon, breast and prostate, and one HCA produced hepatomas in monkeys. The lesions exhibited alteration in genes including Apc, beta-catenin and Ha-ras, and these changes provide clues to the induction mechanisms. The HCAs are oxidized to hydroxyamino derivatives by cytochrome P450s, and further converted to ester forms by acetyltransferase and sulfotransferase. Eventually, they produce DNA adducts through the formation of N-C bonds at guanine bases. There are HCA-sensitive and resistant strains of rodents and a search for the responsible genes is now under way. While the content of HCAs in dishes consumed in ordinary life is low and not sufficient in itself to explain human cancer, the coexistence of many other mutagens/carcinogens of either autobiotic or xenobiotic type and the possibility that HCAs induce genomic instability and heightened sensitivity to tumor promoters suggest that avoidance of exposure to HCAs or reduction of HCAs' biological effects as far as possible are to be highly recommended. Usage of microwave ovens for cooking and supplementation of the diet, for example with soy-isoflavones, which have been found to suppress the occurrence of HCA-induced breast cancers, should be encouraged.

The key role of nitrite and nitrogen oxides in forming N-nitroso compounds by interaction with secondary and tertiary amino compounds has led to the examination worldwide of foods for the presence of N-nitroso compounds, which have been found almost exclusively in those foods containing nitrite or which have become exposed to nitrogen oxides. Among these are cured meats, especially bacon-and especially when cooked; concentrations of 100 micrograms kg(-1) have been found or, more usually, near 10 micrograms kg(-1). This would correspond to consumption of 1 microgram of NDMA in a 100-g portion. Much higher concentrations of NDMA (but lower ones of other nitrosamines) have been found in Japanese smoked and cured fish (more than 100 micrograms kg(-1)). Beer is one source of NDMA, in which as much as 70 micrograms l(-1) has been reported in some types of German beer, although usual levels are much lower (10 or 5 micrograms l(-1)); this could mean a considerable intake for a heavy beer drinker of several liters per day. Levels of nitrosamines have been declining during the past three decades, concurrent with a lowering of the nitrite used in food and greater control of exposure of malt to nitrogen oxides in beer making. There have been declines of N-nitroso compound concentrations in many foods during the past two decades. The small amounts of nitrosamines in food are nonetheless significant because of the possibility-even likelihood-that humans are more sensitive to these carcinogens than are laboratory rodents.

The aim of the present study was to report a snapshot of data on fat in chickens now sold to the public. DESIGN: Samples were obtained randomly between 2004 and 2008 from UK supermarkets, farm shops and a football club. The amount of chicken fat was estimated by emulsification and chloroform/methanol extraction. SETTING: Food sold in supermarkets and farms in England. SUBJECTS: Chicken samples. RESULTS: The fat energy exceeded that of protein. There has been a loss of n-3 fatty acids. The n-6:n-3 ratio was found to be as high as 9:1, as opposed to the recommendation of about 2:1. Moreover, the TAG level in the meat and whole bird mostly exceeded the proportion of phospholipids, which should be the higher for muscle function.

METHODS: Unconditional logistic regression analysis is used to examine cross-sectional associations, adjusting for the effects of age, smoking, alcohol consumption, body mass index, use of sex hormones and parity. RESULTS: The prevalence of degenerative arthritis and soft tissue disorders was 22.60 percent. Women had a higher prevalence than men and prevalence increased greatly with age. Smoking, higher body mass index, never use of contraceptive pills, and current hormone replacement therapy are associated with a higher prevalence of these disorders on multivariate analysis.

AIM OF THE STUDY: Insulin resistance values were assessed in relation to different nutrition. Metabolic abnormality is a predictor of age-related diseases and can be more pronounced in obese subjects. Insulin resistance values in normal weight subjects of two different nutritional habits were correlated with age. METHODS: Fasting concentrations of glucose and insulin as well as calculated values of insulin resistance IR (HOMA) were assessed in two nutritional groups of apparently healthy adult subjects (age range 19 - 64 years) with normal weight (body mass index 18.6 - 25.0 kg/m(2)): a vegetarian group (95 long-term lacto-ovo-vegetarians; duration of vegetarianism 10.2 +/- 0.5 years) and a non-vegetarian control group (107 subjects of general population on traditional western diet). Intake of energy and main nutrients (fats, saccharides, proteins) was similar in both groups. RESULTS: Glucose and insulin concentrations and IR (HOMA) values were significantly lower in vegetarians (glucose 4.47 +/- 0.05 vs. 4.71 +/- 0.07 mmol/l; insulin 4.96 +/- 0.23 vs. 7.32 +/- 0.41 mU/l; IR (HOMA) 0.99 +/- 0.05 vs. 1.59 +/- 0.10). IR (HOMA) dependence on age was only significant in subjects on a western diet. A significant increase of IR was found already in the age range 31-40 years, compared to vegetarians and it continued in later age decades. Age independent and low insulin resistance values in vegetarians are a consequence of an effective diet prevention by long-term frequent consumption of protective food. Vegetarians had a significantly higher consumption of whole grain products, pulses, products from oat and barley.

We tested the hypothesis that the acid load imposed by dietary proteins causes this hypercalciuria. Design and Setting: In a short-term crossover metabolic study, an alkali salt was provided with a high-protein diet (HPD) to neutralize the acid load imparted by dietary proteins. Participants and Interventions: Eleven healthy volunteers were evaluated at the end of each of four phases while consuming metabolic diets with fixed calcium and sodium content. Phases 1 and 3 consisted of a control diet (CD). Phases 2 and 4 consisted of a eucaloric HPD (60 g/d animal proteins added to CD). Along with HPD in phases 2 and 4, subjects ingested 30 mEq twice daily of either potassium citrate (KCitrate, alkaline salt) or potassium chloride (KCl, control neutral salt). Results: KCitrate completely neutralized the acid load imparted by HPD (based on changes in urine pH and net acid excretion) and increased urinary citrate. Urinary calcium increased during both HPD phases compared with CD but was not significantly different between the HPD + KCl and HPD + KCitrate phases (182 ± 85 vs. 170 ± 85 mg/d; P = 0.28). Increased urinary saturation with respect to calcium oxalate and uric acid with HPD was abrogated by KCitrate. Conclusions: This study suggests that, at least in the short-term, mechanism(s) other than acid load account for hypercalciuria induced by HPD.

Both can be defined as disorders in which the saliency of a specific type of reward (food or drug) becomes exaggerated relative to, and at the expense of others rewards. Both drugs and food have powerful reinforcing effects, which are in part mediated by abrupt dopamine increases in the brain reward centres. The abrupt dopamine increases, in vulnerable individuals, can override the brain's homeostatic control mechanisms. These parallels have generated interest in understanding the shared vulnerabilities between addiction and obesity. Predictably, they also engendered a heated debate. Specifically, brain imaging studies are beginning to uncover common features between these two conditions and delineate some of the overlapping brain circuits whose dysfunctions may underlie the observed deficits. The combined results suggest that both obese and drug-addicted individuals suffer from impairments in dopaminergic pathways that regulate neuronal systems associated not only with reward sensitivity and incentive motivation, but also with conditioning, self-control, stress reactivity and interoceptive awareness. In parallel, studies are also delineating differences between them that centre on the key role that peripheral signals involved with homeostatic control exert on food intake.

Their daily urine compositions were analyzed at baseline and at four months. Compliance with dietary recommendations was checked by validated food frequency questionnaires. Compliance with total and animal protein intakes was assessed by 24-hour urea and sulfate outputs, respectively. The nutritional intervention (oral instructions, written leaflet, phoning) and food assessment were carried out by a research dietitian. RESULTS: At baseline, diets and the daily urine composition did not differ between the three groups. At four months, while diets differed significantly, the 24-hour output of calcium and oxalate did not differ significantly within and between groups after adjustment for potential confounders (age, sex, and personal and family history of calcium stones) and baseline values.

DESIGN: This study used a cross-sectional design.

The received particle dose indoors may exceed noticeably the dose from ambient air under routine in-house activities like cooking. In the present work, the internal dose by inhalation of ultrafine and fine particles is assessed, using an appropriate mechanistic model of lung deposition, accommodating aerosol, and inhalation dynamics. The analysis is based on size distribution measurements (10-350 nm) of indoor and outdoor aerosol number concentrations in a typical residence in Athens, Greece. Four different cases are examined, namely, a cooking event, a no activity period indoors and the equivalent time periods outdoors. When the cooking event (frying of bacon-eggs with a gas fire) occurred, the amount of deposited particles deep into the lung of an individual indoors exceeded by up to 10 times the amount received by an individual at the same time period outdoors. The fine particle deposition depends on the level of physical exertion and the hygroscopic properties of the inhaled aerosol. The dose is not found linearly dependant on the indoor/outdoor concentrations during the cooking event, whereas it is during the no activity period. PRACTICAL IMPLICATIONS: The necessity for determining the dose in specific regions of the human lung, as well as the non-linear relationship between aerosol concentration and internal dose makes the application of dosimetry models important. Lung dose of fine and ultrafine particles, during a cooking event, is compared with the dose at no indoor activity and the dose received under outdoor exposure conditions. The dose is expressed in terms of number or surface of deposited particles. This permits to address the dosimetry of very small particles, which are released by many indoor sources but represent a slight fraction of the particulate matter mass. The enhancement of the internal dose resulting from fine and ultrafine particles generated during the cooking event vs. the dose when no indoor source is active is assessed.

METHODS: Nine healthy, normal weight subjects underwent blood oxygenation level dependent (BOLD) fMRI measurements during either intravenous (IV) glucose (0.3 mg/kg), fructose (0.3 mg/kg) or saline, administered over 2 min in a randomized, double-blind, crossover study. Blood was sampled every 5 min during a baseline period and following infusion for 60 min in total for glucose, fructose, lactate and insulin levels. RESULTS: No significant brain BOLD signal changes were detected in response to IV saline. BOLD signal in the cortical control areas increased during glucose infusion (p = 0.002), corresponding with increased plasma glucose and insulin levels. In contrast, BOLD signal decreased in the cortical control areas during fructose infusion (p = 0.006), corresponding with increases of plasma fructose and lactate. Neither glucose nor fructose infusions significantly altered BOLD signal in the hypothalamus. CONCLUSION: In normal weight humans, cortical responses as assessed by BOLD fMRI to infused glucose are opposite to those of fructose. Differential brain responses to these sugars and their metabolites may provide insight into the neurologic basis for dysregulation of food intake during high dietary fructose intake. © 2011 Blackwell Publishing Ltd.", "title": "Brain functional magnetic resonance imaging response to glucose and fructose infusions in humans." }, { "docid": "MED-4407", "text": "Chronic inhalation of cigarette smoke (CS) induces emphysema by the damage contributed by oxidative stress during inhalation of CS. Ingestion of açai fruits (Euterpe oleracea) in animals has both antioxidant and anti-inflammatory effects. This study compared lung damage in mice induced by chronic (60-day) inhalation of regular CS and smoke from cigarettes containing 100mg of hydroalcoholic extract of açai berry stone (CS + A). Sham smoke-exposed mice served as the control group. Mice were sacrificed on day 60, bronchoalveolar lavage was performed, and the lungs were removed for histological and biochemical analyses. Histopathological investigation showed enlargement of alveolar space in CS mice compared to CS + A and control mice. The increase in leukocytes in the CS group was higher than the increase observed in the CS + A group. Oxidative stress, as evaluated by antioxidant enzyme activities, mieloperoxidase, glutathione, and 4-hydroxynonenal, was reduced in mice exposed to CS+A versus CS. Macrophage and neutrophil elastase levels were reduced in mice exposed to CS + A versus CS. Thus, the presence of açai extract in cigarettes had a protective effect against emphysema in mice, probably by reducing oxidative and inflammatory reactions.

However, the role that beef consumption specifically plays in promoting adverse changes in the cardiovascular risk factor profile is unclear. OBJECTIVE: A meta-analysis of randomized, controlled, clinical trials (RCTs) was conducted to evaluate the effects of beef, independent of other red and processed meats, compared with poultry and/or fish consumption, on lipoprotein lipids. METHODS: RCTs published from 1950 to 2010 were considered for inclusion. Studies were included if they reported fasting lipoprotein lipid changes after beef and poultry/fish consumption by subjects free of chronic disease. A total of 124 RCTs were identified, and 8 studies involving 406 subjects met the prespecified entry criteria and were included in the analysis. RESULTS: Relative to the baseline diet, mean ± standard error changes (in mg/dL) after beef versus poultry/fish consumption, respectively, were -8.1 ± 2.8 vs. -6.2 ± 3.1 for total cholesterol (P = .630), -8.2 ± 4.2 vs. -8.9 ± 4.4 for low-density lipoprotein cholesterol (P = .905), -2.3 ± 1.0 vs. -1.9 ± 0.8 for high-density lipoprotein cholesterol (P = .762), and -8.1 ± 3.6 vs. -12.9 ± 4.0 mg/dL for triacylglycerols (P = .367). CONCLUSION: Changes in the fasting lipid profile were not significantly different with beef consumption compared with those with poultry and/or fish consumption.

Potential behavioral effects of dTFA merit investigation. We sought to determine whether dTFA are associated with aggression/irritability. Methodolgy/Prinicpal Findings We capitalized on baseline dietary and behavioral assessments in an existing clinical trial to analyze the relationship of dTFA to aggression. Of 1,018 broadly sampled baseline subjects, the 945 adult men and women who brought a completed dietary survey to their baseline visit are the target of this analysis. Subjects (seen 1999–2004) were not on lipid medications, and were without LDL-cholesterol extremes, diabetes, HIV, cancer or heart disease. Outcomes assessed adverse behaviors with impact on others: Overt Aggression Scale Modified-aggression subscale (primary behavioral endpoint); Life History of Aggression; Conflict Tactics Scale; and self-rated impatience and irritability. The association of dTFA to aggression was analyzed via regression and ordinal logit, unadjusted and adjusted for potential confounders (sex, age, education, alcohol, and smoking). Additional analyses stratified on sex, age, and ethnicity, and examined the prospective association. Greater dTFA were strongly significantly associated with greater aggression, with dTFA more consistently predictive than other assessed aggression predictors. The relationship was upheld with adjustment for confounders, was preserved across sex, age, and ethnicity strata, and held cross-sectionally and prospectively. Conclusions/Significance This study provides the first evidence linking dTFA with behavioral irritability and aggression. While confounding is always a concern in observational studies, factors including strength and consistency of association, biological gradient, temporality, and biological plausibility add weight to the prospect of a causal connection.

However, it is not yet clear how different foodstuffs may promote inflammatory signalling. In a screen of forty filter-sterilised soluble extracts from common foodstuffs, seven were found to induce the secretion of TNF-α and IL-6 from human monocytes in vitro. To investigate what may differentiate inflammatory from non-inflammatory food extracts, stimulants of Toll-like receptor (TLR) 2 and TLR4 were quantified using human embryonic kidney-293 cells transfected with each TLR, and calibrated with defined bacterial lipopeptide (BLP) and lipopolysaccharide (LPS) standards. These assays revealed that while most foods contained undetectable levels of TLR2 or TLR4 stimulants, all TNF-α-inducing foods contained stimulants of either TLR2 (up to 1100 ng BLP-equivalent/g) or TLR4 (up to 2700 ng LPS-equivalent/g) in both the soluble and insoluble fractions. TLR stimulants were present mainly in meat products and processed foods, but were minimal or undetectable in fresh fruit and vegetables. The capacity of food extracts to induce TNF-α secretion in monocytes correlated with the content of both TLR2 (r 0·837) and TLR4 stimulants (r 0·748), and was completely abolished by specific inhibition of TLR2 and TLR4. LPS and BLP were found to be highly resistant to typical cooking times and temperatures, low pH and protease treatment.

(HS) in the treatment of risk factors associated with cardiovascular disease is assessed in this review by taking a comprehensive approach to interpreting the randomized clinical trial (RCT) results in the context of the available ethnomedical, phytochemical, pharmacological, and safety and toxicity information. HS decoctions and infusions of calyxes, and on occasion leaves, are used in at least 10 countries worldwide in the treatment of hypertension and hyperlipidemia with no reported adverse events or side effects. HS extracts have a low degree of toxicity with a LD50 ranging from 2,000 to over 5,000 mg/kg/day. There is no evidence of hepatic or renal toxicity as the result of HS extract consumption, except for possible adverse hepatic effects at high doses. There is evidence that HS acts as a diuretic, however in most cases the extract did not significantly influence electrolyte levels. Animal studies have consistently shown that consumption of HS extract reduces blood pressure in a dose dependent manner. In RCTs, the daily consumption of a tea or extract produced from HS calyxes significantly lowered systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adults with pre to moderate essential hypertension and type 2 diabetes. In addition, HS tea was as effective at lowering blood pressure as the commonly used blood pressure medication Captropril, but less effective than Lisinopril. Total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides were lowered in the majority of normolipidemic, hypolipidemic, and diabetic animal models, whereas high-density lipoprotein cholesterol (HDL-C) was generally not affected by the consumption of HS extract. Over half of the RCTs showed that daily consumption of HS tea or extracts had favorable influence on lipid profiles including reduced total cholesterol, LDL-C, triglycerides, as well as increased HDL-C. Anthocyanins found in abundance in HS calyxes are generally considered the phytochemicals responsible for the antihypertensive and hypocholesterolemic effects, however evidence has also been provided for the role of polyphenols and hibiscus acid. A number of potential mechanisms have been proposed to explain the hypotensive and anticholesterol effects, but the most common explanation is the antioxidant effects of the anthocyanins inhibition of LDL-C oxidation, which impedes atherosclerosis, an important cardiovascular risk factor.

There are good reasons for long-standing recommendations that dietary cholesterol should be limited to less than 200 mg/day; a single large egg yolk contains approximately 275 mg of cholesterol (more than a day’s worth of cholesterol). Although some studies showed no harm from consumption of eggs in healthy people, this outcome may have been due to lack of power to detect clinically relevant increases in a low-risk population. Moreover, the same studies showed that among participants who became diabetic during observation, consumption of one egg a day doubled their risk compared with less than one egg a week. Diet is not just about fasting cholesterol; it is mainly about the postprandial effects of cholesterol, saturated fats, oxidative stress and inflammation. A misplaced focus on fasting lipids obscures three key issues. Dietary cholesterol increases the susceptibility of low-density lipoprotein to oxidation, increases postprandial lipemia and potentiates the adverse effects of dietary saturated fat. Dietary cholesterol, including egg yolks, is harmful to the arteries. Patients at risk of cardiovascular disease should limit their intake of cholesterol. Stopping the consumption of egg yolks after a stroke or myocardial infarction would be like quitting smoking after a diagnosis of lung cancer: a necessary action, but late.

Les recommandations de longue date qui préconisent de limiter le cholestérol alimentaire à moins de 200 mg/jour reposent sur de bonnes raisons. Un seul gros jaune d’œuf contient environ 275 mg de cholestérol (plus que la portion quotidienne de cholestérol).

However, these relative risks have never been directly juxtaposed to determine whether an increase in relative risk by 1 activity could be neutralized by an opposing change in relative risk from a second activity. The investigators compared the increase in relative risk for cardiovascular disease associated with the total fat and trans fat content of fast foods against the relative risk decrease provided by daily statin consumption from a meta-analysis of statins in primary prevention of coronary artery disease (7 randomized controlled trials including 42,848 patients). The risk reduction associated with the daily consumption of most statins, with the exception of pravastatin, is more powerful than the risk increase caused by the daily extra fat intake associated with a 7-oz hamburger (Quarter Pounder) with cheese and a small milkshake. In conclusion, statin therapy can neutralize the cardiovascular risk caused by harmful diet choices. In other spheres of human activity, individuals choosing risky pursuits (motorcycling, smoking, driving) are advised or compelled to use measures to minimize the risk (safety equipment, filters, seatbelts). Likewise, some individuals eat unhealthily. Routine accessibility of statins in establishments providing unhealthy food might be a rational modern means to offset the cardiovascular risk.

All subjects purchased and prepared their own food. Following initial screening, subjects were given one week to prepare for the fast, after which time they reported to the lab for their pre-intervention assessment (day 1). After the 21 day fast, subjects reported to the lab for their post-intervention assessment (day 22). For both visits, subjects reported in a 12 hr fasted state, performing no strenuous physical activity during the preceding 24-48 hrs. At each visit, mental and physical health (SF-12 form), resting heart rate and blood pressure, and anthropometric variables were measured. Blood was collected for determination of complete blood count, metabolic panel, lipid panel, insulin, HOMA-IR, and C-reactive protein (CRP). Subjects' self-reported compliance, mood, and satiety in relation to the fast were also recorded. Diet records were maintained by all subjects during the 7 day period immediately prior to the fast (usual intake) and during the final 7 days of the fast. Results Subjects' compliance to the fast was 98.7 ± 0.2% (mean ± SEM). Using a 10 point scale, subjects' mood and satiety were both 7.9 ± 0.2.

Serum chemistry and 24-hour urine samples collected at the end of each phase were compared using mixed model repeated measures analysis. RESULTS: Serum and urinary uric acid were increased for each phase. Beef was associated with lower serum uric acid than chicken or fish (6.5 vs 7.0 and 7.3 mg/dl, respectively, each p <0.05). Fish was associated with higher urinary uric acid than beef or chicken (741 vs 638 and 641 mg per day, p = 0.003 and 0.04, respectively).

Furthermore, phasic dopamine signaling to palatable food receipt decreases after repeated intake of that food, which collectively suggests that frequent intake of an energy-dense food may reduce striatal response to receipt of that food. Objective: We tested the hypothesis that frequent ice cream consumption would be associated with reduced activation in reward-related brain regions (eg, striatum) in response to receipt of an ice cream–based milkshake and examined the influence of adipose tissue and the specificity of this relation. Design: Healthy-weight adolescents (n = 151) underwent fMRI during receipt of a milkshake and during receipt of a tasteless solution. Percentage body fat, reported food intake, and food craving and liking were assessed. Results: Milkshake receipt robustly activated the striatal regions, yet frequent ice cream consumption was associated with a reduced response to milkshake receipt in these reward-related brain regions. Percentage body fat, total energy intake, percentage of energy from fat and sugar, and intake of other energy-dense foods were not related to the neural response to milkshake receipt. Conclusions: Our results provide novel evidence that frequent consumption of ice cream, independent of body fat, is related to a reduction in reward-region responsivity in humans, paralleling the tolerance observed in drug addiction. Data also imply that intake of a particular energy-dense food results in attenuated reward-region responsivity specifically to that food, which suggests that sensory aspects of eating and reward learning may drive the specificity.", "title": "Frequent ice cream consumption is associated with reduced striatal response to receipt of an ice cream–based milkshake" }, { "docid": "MED-1651", "text": "Background Limited information is available regarding the impact of candy consumption on health.

Methods Using data collected in the 2003–2006 National Health and Nutrition Examination Surveys (NHANES), adults were categorized as infrequent (≤ 3 eating occasions [EO]/month), moderate (> 3 EO/month and ≤ 3.5 EO/week), or frequent (> 3.5 EO/week) candy consumers based on the combined frequency of chocolate and other candy consumption over the previous 12 months. Weight and adiposity status were analyzed using logistic regression models, and blood pressure, lipids, and insulin sensitivity were analyzed using linear regression models. Models were adjusted for age, sex and race/ethnicity, and also for additional covariates with potential associations with the outcomes. Appropriate statistical weights were used to yield results generalizable to the US population. Results Frequency of candy consumption was not associated with the risk of obesity, overweight/obesity, elevated waist circumference, elevated skinfold thickness, blood pressure, low density lipoprotein (LDL) or high density lipoprotein (HDL) cholesterol, triglycerides, or insulin resistance. Increased frequency of candy consumption was associated with higher energy intakes and higher energy adjusted intakes of carbohydrates, total sugars and added sugars, total fat, saturated fatty acids and monounsaturated fatty acids (p < 0.05), and lower adjusted intakes of protein and cholesterol (p < 0.001). Conclusions Increased frequency of candy consumption among adults in the United States was not associated with objective measures of adiposity or select cardiovascular risk factors, despite associated dietary differences. Given the cross-sectional study design, however, it cannot be concluded that candy consumption does not cause obesity or untoward levels of cardiovascular risk markers.

RESEARCH DESIGN AND METHODS Subjects (n = 54) were given a high-fat meal (75 g fat, 5 g carbohydrate, 6 g protein) after an overnight fast (nonobese control [NOC]: age 39.9 ± 11.8 years [mean ± SD], BMI 24.9 ± 3.2 kg/m2, n = 9; obese: age 43.8 ± 9.5 years, BMI 33.3 ± 2.5 kg/m2, n = 15; impaired glucose tolerance [IGT]: age 41.7 ± 11.3 years, BMI 32.0 ± 4.5 kg/m2, n = 12; type 2 diabetic: age 45.4 ± 10.1 years, BMI 30.3 ± 4.5 kg/m2, n = 18). Blood was collected before (0 h) and after the meal (1–4 h) for analysis. RESULTS Baseline endotoxin was significantly higher in the type 2 diabetic and IGT subjects than in NOC subjects, with baseline circulating endotoxin levels 60.6% higher in type 2 diabetic subjects than in NOC subjects (P < 0.05). Ingestion of a high-fat meal led to a significant rise in endotoxin levels in type 2 diabetic, IGT, and obese subjects over the 4-h time period (P < 0.05). These findings also showed that, at 4 h after a meal, type 2 diabetic subjects had higher circulating endotoxin levels (125.4%↑) than NOC subjects (P < 0.05). CONCLUSIONS These studies have highlighted that exposure to a high-fat meal elevates circulating endotoxin irrespective of metabolic state, as early as 1 h after a meal. However, this increase is substantial in IGT and type 2 diabetic subjects, suggesting that metabolic endotoxinemia is exacerbated after high fat intake. In conclusion, our data suggest that, in a compromised metabolic state such as type 2 diabetes, a continual snacking routine will cumulatively promote their condition more rapidly than in other individuals because of the greater exposure to endotoxin.", "title": "High Fat Intake Leads to Acute Postprandial Exposure to Circulating Endotoxin in Type 2 Diabetic Subjects" }, { "docid": "MED-3231", "text": "This review looks at the role of an alkaline diet in health.

Although there might be various different triggering events in the early stages of the disease, they seem to converge on a few characteristic final pathways in the late stages, characterized by inflammation and neurodegeneration. In this review, we put forward the hypothesis that advanced glycation end products (AGEs) and their precursors, including methylglyoxal, are both biomarkers and causative agents (\"gerontotoxins\") characteristic for this disorder. Accumulation of AGEs is a normal feature of aging, but is accelerated in AD, where AGEs can be detected in amyloid plaques and neurofibrillary tangles. AGE modification may explain many of the neuropathological and biochemical features of AD such as extensive protein cross-linking, inflammation, oxidative stress and neuronal cell death. We suggest that methylglyoxal is one of the major carbonyl species responsible for the formation of AGEs. We propose that one promising pharmacological approach to prevent the formation of AGEs would be to lower the methylglyoxal concentration. This can be achieved, for example, by decreasing the concentration of methylglyoxal precursors such as d-glyceraldehyde-3-phosphate by allowing a higher flux through the pentose phosphate pathway or by increasing methylglyoxal detoxification through the glyoxalase system. Alternatively, methylglyoxal could be scavenged by various types of carbonyl scavengers. Copyright © 2010 Elsevier Inc.

However, the mechanisms, underlying neuroanatomy, and specificity of this neuroanatomy are not yet fully understood. METHOD: To address these issues, experienced cocaine users (N=17) and comparison subjects (N=14) underwent functional magnetic resonance imaging while viewing three separate films that portrayed 1 ) individuals smoking crack cocaine, 2) outdoor nature scenes, and 3) explicit sexual content. Candidate craving sites were identified as those that showed significant activation in the cocaine users when viewing the cocaine film. These sites were then required to show significantly greater activation when contrasted with comparison subjects viewing the cocaine film (population specificity) and cocaine users viewing the nature film (content specificity). RESULTS: Brain regions that satisfied these criteria were largely left lateralized and included the frontal lobe (medial and middle frontal gyri, bilateral inferior frontal gyrus), parietal lobe (bilateral inferior parietal lobule), insula, and limbic lobe (anterior and posterior cingulate gyrus). Of the 13 regions identified as putative craving sites, just three (anterior cingulate, right inferior parietal lobule, and the caudate/lateral dorsal nucleus) showed significantly greater activation during the cocaine film than during the sex film in the cocaine users, which suggests that cocaine cues activated similar neuroanatomical substrates as naturally evocative stimuli in the cocaine users. Finally, contrary to the effects of the cocaine film, cocaine users showed a smaller response than the comparison subjects to the sex film. CONCLUSIONS: These data suggest that cocaine craving is not associated with a dedicated and unique neuroanatomical circuitry; instead, unique to the cocaine user is the ability of learned, drug-related cues to produce brain activation comparable to that seen with nondrug evocative stimuli in healthy comparison subjects.", "title": "Cue-induced cocaine craving: neuroanatomical specificity for drug users and drug stimuli." }, { "docid": "MED-4206", "text": "Vegetarian diets are rich in antioxidant phytochemicals.

RESULTS: In cross-sectional surveys, all pooled r values for the relation between protein intake and bone mineral density (BMD) or bone mineral content at the main clinically relevant sites were significant and positive; protein intake explained 1-2% of BMD. A meta-analysis of randomized placebo-controlled trials indicated a significant positive influence of all protein supplementation on lumbar spine BMD but showed no association with relative risk of hip fractures. No significant effects were identified for soy protein or milk basic protein on lumbar spine BMD. CONCLUSIONS: A small positive effect of protein supplementation on lumbar spine BMD in randomized placebo-controlled trials supports the positive association between protein intake and bone health found in cross-sectional surveys. However, these results were not supported by cohort study findings for hip fracture risk. Any effects found were small and had 95% CIs that were close to zero.

Overeating in some obese individuals shares similarities with the loss of control and compulsive behavior observed in drug-addicted subjects, suggesting that obesity may involve food addiction. Here, we review the contributions provided by the use of positron emission tomography to the current understanding of the cerebral control of obesity and food intake in humans. The available studies have shown that multiple areas in the brain are involved with the reward properties of food, such as prefrontal, orbitofrontal, somatosensory cortices, insula, thalamus, hypothalamus, amygdala, and others. This review summarizes the current evidence, supporting the concepts that i) regions involved in the somatosensory response to food sight, taste, and smell are activated by palatable foods and may be hyperresponsive in obese individuals, ii) areas controlling executive drive seem to overreact to the anticipation of pleasure during cue exposure, and iii) those involved in cognitive control and inhibitory behavior may be resistant to the perception of reward after food exposure in obese subjects. All of these features may stimulate, for different reasons, ingestion of highly palatable and energy-rich foods. Though these same regions are similarly involved in drug abusers and game-addicted individuals, any direct resemblance may be an oversimplification, especially as the heterogeneities between studies and the prevalent exclusion of sensitive groups still limit a coherent interpretation of the findings.

Polybrominated diphenyl ethers (PBDEs) and hexabromocyclodecane (HBCD) in composite U.S. food samples, Environ Health Perspect 118:357–362]. Methods In this study we measured concentrations of 32 organochlorine pesticides, 7 PCBs, and 11 PFCs in composite samples of 31 different types of food (310 individual food samples) purchased from supermarkets in Dallas, Texas (USA), in 2009. Dietary intake of these chemicals was calculated for an average American. Results Contamination varied greatly among chemical and food types. The highest level of pesticide contamination was from the dichlorodiphenyltrichloroethane (DDT) metabolite p,p′- dichlorodiphenyldichloroethylene, which ranged from 0.028 ng/g wet weight (ww) in whole milk yogurt to 2.3 ng/g ww in catfish fillets. We found PCB congeners (28, 52, 101, 118, 138, 153, and 180) primarily in fish, with highest levels in salmon (PCB-153, 1.2 ng/g ww; PCB-138, 0.93 ng/g ww). For PFCs, we detected perfluorooctanoic acid (PFOA) in 17 of 31 samples, ranging from 0.07 ng/g in potatoes to 1.80 ng/g in olive oil. In terms of dietary intake, DDT and DDT metabolites, endosulfans, aldrin, PCBs, and PFOA were consumed at the highest levels. Conclusion Despite product bans, we found POPs in U.S. food, and mixtures of these chemicals are consumed by the American public at varying levels.

The aims of this study were to characterize patients who believe they have NCGS. Materials and Methods: Advertising was directed toward adults who believed they had NCGS and were willing to participate in a clinical trial. Respondents were asked to complete a questionnaire about symptoms, diet, and celiac investigation. Results: Of 248 respondents, 147 completed the survey. Mean age was 43.5 years, and 130 were women. Seventy-two percent did not meet the description of NCGS due to inadequate exclusion of celiac disease (62%), uncontrolled symptoms despite gluten restriction (24%), and not following a GFD (27%), alone or in combination. The GFD was self-initiated in 44% of respondents; in other respondents it was prescribed by alternative health professionals (21%), dietitians (19%), and general practitioners (16%). No celiac investigations had been performed in 15% of respondents. Of 75 respondents who had duodenal biopsies, 29% had no or inadequate gluten intake at the time of endoscopy. Inadequate celiac investigation was common if the GFD was initiated by self (69%), alternative health professionals (70%), general practitioners (46%), or dietitians (43%). In 40 respondents who fulfilled the criteria for NCGS, their knowledge of and adherence to the GFD were excellent, and 65% identified other food intolerances. Conclusions: Just over 1 in 4 respondents self-reporting as NCGS fulfill criteria for its diagnosis. Initiation of a GFD without adequate exclusion of celiac disease is common.

The antimicrobial activities of the diallyl sulfides increased with the number of sulfur atoms (diallyl sulfide < diallyl disulfide < diallyl trisulfide).

With such long experience with their use, it is easy to understand why these substances have been regarded as safe. They are currently used for a variety of preservative properties, including controlling microbial growth, preventing browning and spoilage, and bleaching some foods. It is estimated that up to 500,000 (< .05% of the population) sulfite-sensitive individuals live in the United States. Sulfite sensitivity occurs most often in asthmatic adults--predominantly women; it is uncommonly reported in preschool children. Adverse reactions to sulfites in nonasthmatics are extremely rare. Asthmatics who are steroid-dependent or who have a higher degree of airway hyperreactivity may be at greater risk of experiencing a reaction to sulfite-containing foods. Even within this limited population, sulfite sensitivity reactions vary widely, ranging from no reaction to severe. The majority of reactions are mild. These manifestations may include dermatologic, respiratory, or gastrointestinal signs and symptoms. Severe nonspecific signs and symptoms occur less commonly. Broncho-constriction is the most common sensitivity response in asthmatics. The precise mechanisms of the sensitivity responses have not been completely elucidated.

Serum samples from all participants were tested for immunoglobulin A (IgA) tissue transglutaminase antibodies and, if findings were abnormal, also for IgA endomysial antibodies. Information about prior diagnosis of CD and use of a gluten-free diet (GFD) was obtained by direct interview. CD was defined as having either double-positive serology (serologically diagnosed CD) or a reported diagnosis of CD by a doctor or other health-care professional and being on a GFD (reported clinical diagnosis of CD).

V. cholerae O75 was isolated from a water sample collected from a pond in Louisiana in 2004. Subsequently, 3 V. cholerae isolates from Louisiana (2 from patients with diarrhea in 2000 and 1 from a water sample collected in 1978) that had been previously reported as serogroup O141 were also discovered to be serogroup O75. RESULTS: All 8 patients who were infected with V. cholerae O75 were adults who became ill after consuming seafood; 2 had eaten raw oysters traced back to the Gulf Coast of the United States. All 10 isolates possessed the cholera toxin gene and were susceptible to 10 antimicrobials.

The aerobic group exercised under the supervision of a fitness trainer at 75% to 85% of heart rate reserve for 45 to 60 min/d, 4 d/wk for 6 months. The control group carried out supervised stretching activities according to the same schedule but maintained their heart rate at or below 50% of their heart rate reserve.

Results Six months of high-intensity aerobic exercise had sex-specific effects on cognition, glucose metabolism, and hypothalamic-pituitary-adrenal axis and trophic activity despite comparable gains in cardiorespiratory fitness and body fat reduction.

However, unlike nonpickled vegetables, pickled vegetable intake and its proportion relative to total vegetables were positively associated with the risk of breast cancer, and this association was more profound and consistent when pickled vegetable intake was considered as a proportion relative to total vegetables (odds ratio [OR] = 6.24, 95% confidence interval [CI] = 3.55-10.97; P for trend <0.001 for highest vs. lowest quartiles of intake) than as the absolute consumed amount (OR = 2.47, 95% CI = 1.45-4.21; P for trend = 0.015 for highest vs. lowest quartiles of intake).

In light of the consensus that obesity is a significant public health concern and that many weight-loss interventions have been unsuccessful in the long term, an exploration of food patterns that are beneficial in the primary prevention of obesity is warranted. The focus of this article is to review the relation between vegetarian diets and obesity, particularly as they relate to childhood obesity. Epidemiologic studies indicate that vegetarian diets are associated with a lower body mass index (BMI) and a lower prevalence of obesity in adults and children. A meta-analysis of adult vegetarian diet studies estimated a reduced weight difference of 7.6 kg for men and 3.3 kg for women, which resulted in a 2-point lower BMI (in kg/m(2)). Similarly, compared with nonvegetarians, vegetarian children are leaner, and their BMI difference becomes greater during adolescence. Studies exploring the risk of overweight and food groups and dietary patterns indicate that a plant-based diet seems to be a sensible approach for the prevention of obesity in children. Plant-based diets are low in energy density and high in complex carbohydrate, fiber, and water, which may increase satiety and resting energy expenditure. Plant-based dietary patterns should be encouraged for optimal health and environmental benefits.

Therefore, we evaluated the effects of comprehensive lifestyle changes on prostate specific antigen (PSA), treatment trends and serum stimulated LNCaP cell growth in men with early, biopsy proven prostate cancer after 1 year. MATERIALS AND METHODS: Patient recruitment was limited to men who had chosen not to undergo any conventional treatment, which provided an unusual opportunity to have a nonintervention randomized control group to avoid the confounding effects of interventions such as radiation, surgery or androgen deprivation therapy. A total of 93 volunteers with serum PSA 4 to 10 ng/ml and cancer Gleason scores less than 7 were randomly assigned to an experimental group that was asked to make comprehensive lifestyle changes or to a usual care control group. RESULTS: None of the experimental group patients but 6 control patients underwent conventional treatment due to an increase in PSA and/or progression of disease on magnetic resonance imaging. PSA decreased 4% in the experimental group but increased 6% in the control group (p = 0.016). The growth of LNCaP prostate cancer cells (American Type Culture Collection, Manassas, Virginia) was inhibited almost 8 times more by serum from the experimental than from the control group (70% vs 9%, p <0.001). Changes in serum PSA and also in LNCaP cell growth were significantly associated with the degree of change in diet and lifestyle. CONCLUSIONS: Intensive lifestyle changes may affect the progression of early, low grade prostate cancer in men.

Activation of AMPK by metformin or an adenosine analogue suppresses expression of SREBP-1, a key lipogenic transcription factor. In metformin-treated rats, hepatic expression of SREBP-1 (and other lipogenic) mRNAs and protein is reduced; activity of the AMPK target, ACC, is also reduced.

METHODS Ninety-eight adult male CD-1 mice underwent 90-minute transient middle cerebral artery occlusion (tMCAO). Metformin (200 mg/kg) was administrated for up to 14 days. Neurobehavioral outcomes, brain infarct volume, inflammatory factors, blood-brain barrier (BBB) permeability and AMPK signaling pathways were evaluated following tMCAO. Oxygen glucose deprivation was performed on bEND.3 cells to explore the mechanisms of metformin in inhibiting inflammatory signaling pathways. RESULTS Infarct volume was reduced in metformin-treated mice compared to the control group following tMCAO (P < 0.05). Neurobehavioral outcomes were greatly improved in metformin-treated mice (P < 0.05). MPO+ cells, Gr1+ cells, MPO activity and BBB permeability were decreased after metformin administration (P < 0.05).

Understanding the mechanisms of resistance is important in the development of strategies to solving the problem. Active efflux of drugs, alteration of target sites and enzymatic degradations are the strategies by which pathogenic bacteria acquire or develop intrinsic resistance to antibiotics. Multi-drug resistance (MDR) pumps, capable of recognizing and expelling a variety of structurally unrelated compounds from the bacterial cell and conferring resistance to a wide range of antibiotics have since been characterized in many gram positive and gram negative pathogens like Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and, more recently, in mycobacteria. The ability of some chemical compounds (called MDR inhibitors or resistance modifying agents) to modify the resistance phenotype in bacteria by working synergistically with antibiotics in vitro has since been observed. The search for such compounds which can be combined with antibiotics in the treatment of drug resistant infections may be an alternative to overcoming the problem of resistance in bacteria.

Activation of HIV-1 gene expression in these cells together with an efficient HAART has been proposed as an adjuvant therapy aimed at decreasing the pool of latent viral reservoirs. Using the latently-infected U1 monocytic cell line and latently-infected J-Lat T-cell clones, we here demonstrated a strong synergistic activation of HIV-1 production by clinically used histone deacetylase inhibitors (HDACIs) combined with prostratin, a non-tumor-promoting nuclear factor (NF)- kappaB inducer. In J-Lat cells, we showed that this synergism was due, at least partially, to the synergistic recruitment of unresponsive cells into the expressing cell population. A combination of prostratin+HDACI synergistically activated the 5' Long Terminal Repeat (5'LTR) from HIV-1 Major group subtypes representing the most prevalent viral genetic forms, as shown by transient transfection reporter assays. Mechanistically, HDACIs increased prostratin-induced DNA-binding activity of nuclear NF-kappaB and degradation of cytoplasmic NF-kappaB inhibitor, IkappaBalpha . Moreover, the combined treatment prostratin+HDACI caused a more pronounced nucleosomal remodeling in the U1 viral promoter region than the treatments with the compounds alone. This more pronounced remodeling correlated with a synergistic reactivation of HIV-1 transcription following the combined treatment prostratin+HDACI, as demonstrated by measuring recruitment of RNA polymerase II to the 5'LTR and both initiated and elongated transcripts. The physiological relevance of the prostratin+HDACI synergism was shown in CD8(+)-depleted peripheral blood mononuclear cells from HAART-treated patients with undetectable viral load.

However, the effects of PP2A down-regulation on site-specific tau hyperphosphorylation is not well understood. In the present study, we showed that PP2A dephosphorylated tau at several phosphorylation sites with different efficiencies. Among the sites studied, Thr205, Thr212, Ser214, and Ser262 were the most favorable sites, and Ser199 and Ser404 were the least favorable sites for PP2A in vitro. Inhibition of PP2A with okadaic acid in metabolically active rat brain slices caused inhibition of glycogen synthase kinase-3beta (GSK-3beta) via an increase in its phosphorylation at Ser9. GSK-3beta phosphorylated tau at many sites, with Ser199, Thr205, and Ser396 being the most favorable sites in cells. The overall alterations in tau phosphorylation induced by PP2A inhibition were the result of the combined effects of both reduced tau dephosphorylation due to PP2A inhibition directly and reduced phosphorylation by GSK-3beta due to its inhibition.

However, the synergistic activity and mechanism(s) of pleurocidin in combination with conventional antibiotics, and the antibiofilm effect of the peptide are poorly understood. METHODS The interaction between pleurocidin and antibiotics was evaluated using checkerboard assay. To study the mechanism(s) involved in their synergism, we detected hydroxyl radical formation using 3'-(p-hydroxyphenyl) fluorescein, measured the NAD(+)/NADH ratio by NAD(+) cycling assay, observed change in bacterial viability with the hydroxyl radical scavenger thiourea, and investigated cytoplasmic membrane damage using propidium iodide. Also, the antibiofilm effect of pleurocidin was examined with the tissue culture plate method. RESULTS All combinations of pleurocidin and antibiotics showed synergistic interaction against bacterial strains (fractional inhibitory concentration index (FICI)≤0.5) except for Enterococcus faecium treated with a combination of the peptide and ampicillin (FICI=0.75). We identified that pleurocidin alone and in combinations with antibiotics induced formation of hydroxyl radicals. The oxidative stress was caused by a transient NADH depletion and the addition of thiourea prevented bacterial death, especially in the case of the combined treatment of pleurocidin and ampicillin showing synergisms. The combination of pleurocidin and erythromycin increased permeability of bacterial cytoplasmic membrane. Additionally, pleurocidin exhibited a potent inhibitory effect on preformed biofilm of bacterial organisms.

RNA interference of fascin reduced the number of filopodia, and remaining filopodia had abnormal morphology with wavy and loosely bundled actin organization.

The constitutively active fascin mutant S39A increased the number and length of filopodia, whereas the inactive fascin mutant S39E reduced filopodia frequency.

We found that ZOL and SAHA cooperated to induce cell death in the prostate cancer cell lines LNCaP and PC-3. The effect was synergistic, as evidenced by combination index isobologram analysis. ZOL and SAHA synergized to induce dissipation of the mitochondrial transmembrane potential, to activate caspase-3, and to trigger DNA fragmentation, showing that the combination of ZOL and SAHA resulted in the initiation of apoptosis.

Additionally, a PI 3-kinase activity which generates phosphatidylinositol 3-phosphate has been shown to be required for protein trafficking in yeast. RESULTS We have identified a family of three distinct PI 3-kinases in Drosophila, using an approach based on the polymerase chain reaction to amplify a region corresponding to the conserved catalytic domain of PI 3-kinases. One of these family members, PI3K_92D, is closely related to the prototypical PI 3-kinase, p110 alpha; PI3K_59F is homologous to Vps34p, whereas the third, PI3K_68D, is a novel PI 3-kinase which is widely expressed throughout the Drosophila life cycle. The PI3K_68D cDNA encodes a protein of 210 kDa, which lacks sequences implicated in linking p110 PI 3-kinases to p85 adaptor proteins, but contains an amino-terminal proline-rich sequence, which could bind to SH3 domains, and a carboxy-terminal C2 domain. Biochemical analyses demonstrate that PI3K_68D has a novel substrate specificity in vitro, restricted to phosphatidylinositol and phosphatidylinositol 4-phosphate, and is unable to phosphorylate phosphatidylinositol (4,5)-bisphosphate, the implied in vivo substrate for p110.

Simultaneous targeting of β1 integrin and EGFR was shown to have a higher radiosensitizing potential than mono-targeting in the majority of tested HNSCC cancer models. As tumor-initiating cells (TIC) are thought to play a key role for therapy resistance and recurrence and can be enriched in sphere forming conditions, this study investigated the efficacy of β1 integrin/EGFR targeting without and in combination with X-ray irradiation on the behavior of sphere-forming cells (SFC). METHODS HNSCC cell lines (UTSCC15, UTSCC5, Cal33, SAS) were injected subcutaneously into nude mice for tumor up-take and plated for primary and secondary sphere formation under non-adhesive conditions which is thought to reflect the enrichment of SFC and their self-renewal capacity, respectively. Treatment was accomplished by inhibitory antibodies for β1 integrin (AIIB2) and EGFR (Cetuximab) as well as X-ray irradiation (2 - 6 Gy single doses). Further, flow cytometry for TIC marker expression and cell cycling as well as Western blotting for DNA repair protein expression and phosphorylation were employed. RESULTS We found higher primary and secondary sphere forming capacity of SAS cells relative to other HNSCC cell lines, which was in line with the tumor up-take rates of SAS versus UTSCC15 cells. AIIB2 and Cetuximab administration had minor cytotoxic and no radiosensitizing effects on SFC. Intriguingly, secondary SAS spheres, representing the fraction of surviving SFC upon passaging, showed greatly enhanced radiosensitivity compared to primary spheres. Intriguingly, neither AIIB2 nor Cetuximab significantly altered basal sphere forming capacity and radiosensitivity. While an increased accumulation of G0/G1 phase cells was observable in secondary SAS spheres, DNA double strand break repair indicated no difference on the basis of significantly enhanced ATM and Chk2 dephosphorylation upon irradiation. CONCLUSIONS In the HNSCC model, sphere-forming conditions select for cells, which are unsusceptible to both anti-β1 integrin and anti-EGFR inhibitory antibodies.

Instead, let's say that you paid the hospital $1696 today, and invested the $37.68 per month. At the end of 5 years, assuming the same 6% growth and 25% tax bracket, your investment will be worth $2552. In order for you to come out ahead by investing today and paying off the hospital over time, you would need to get at least a 17% growth on your investment. If you are ignoring taxes, then the number you need to hit is at least 13%. Conclusion: You will come out ahead by paying the hospital today, and investing the monthly payment plan that you avoided. (Note: Bankrate has a very handy investment calculator that makes it easy to calculate returns on a monthly investment.) Now, let's look at the ethics of the situation. Assume that you were able somehow to find an investment with a guaranteed return high enough to come out ahead with your plan. Should you do it? The hospital has provided you a service, and you owe the money. As a public service to people that cannot pay the bill, they allow people to pay off the bill over time at no interest. However, you are not one of these people. You have the money to pay.

If you subscribe for new shares (like in an Initial Public Offering), it is very straightforward to say \"\"I have provided capital to the corporation, which it is using to advance its business.\"\" If you buy shares that already exist (like in a typical share purchase on a public exchange), your money doesn't go to the company. Instead, it goes to someone who paid someone who paid someone who paid someone (etc.) who originally contributed money to the corporation. In theory, the value of a share price does not directly impact the operation of the company itself, apart from what @DanielCarson aptly noted (employee stock options are affected by share price, impacting morale, etc.). This is because in theory, the true value of a company (and thus, the value of a share) is the present value of all future cashflows (dividends + final liquidation). This means that in a technical sense, a company's share price should result from the company's value. The company's true value does not result from the share price. But what you are doing as a shareholder is impacting the liquidity available to other potential investors (also as mentioned by @DanielCarson, in reference to the desirability for future financing). The more people who invest their money in the stock market, the more liquid those stocks become. This is the true value you add to the economy by investing in stocks - you add liquidity to the market, decreasing the risk of capital investment generally. The fewer people there are who are willing to invest in a particular company, the harder it is for an investor to buy or sell shares at will. If it is difficult to sell shares in a company, the risk of holding shares in that company is higher, because you can't \"\"cash out\"\" as easily. This increased risk then does change the value of the shares - because even though the corporation's internal value is the same, the projected cashflows of the shares themselves now has a question mark around the ability to sell when desired. Whether this actually has an impact on anything depends on how many people join you in your declaration of ethical investing. Like many other forms of social activism, success relies on joint effort.

You want to make sure that as your stocks appreciate, you sell some every year and immediately rebuy them so that you pay a small tax bill every year rather than one huge tax bill 20 years from now. Claiming about $20600 of capital gains every year would be tax free assuming you are not earning any other money. I would claim a bit more in years where you make a lot. You can mitigate your long term capital gains tax exposure by opening a Roth IRA and maxing that out. Capital gains in the Roth IRA are not taxable. Even if you don't have income from working, you can have some income if you invest in stocks that pay dividends, which would allow you to contribute to a Roth IRA.

If the exchange rate were to change by a lot, you might find yourself a lot poorer.

There is little clinical trial data to guide therapy, hindering the identification of best therapy. Despite the recognition of adverse effects, gastric lavage is commonly done in Asia. We aimed to identify studies assessing its effectiveness. METHOD We systematically searched the literature for controlled clinical studies that assessed the effect of gastric lavage in OP pesticide self-poisoning. RESULTS All 56 studies identified were Chinese and reported benefit from the intervention studied, including multiple gastric lavages, use of norepinephrine or pralidoxime in the lavage fluid, concurrent treatment with naloxone or scopolamine, insertion of the gastric tube via a laparotomy incision, and lavage later than 12 h post-ingestion. However, only 23 were RCTs and none presented adequate methodology for their quality to be assessed. The patient population and study treatment protocol were not defined - large variation in case fatality in the control arm of the studies (from 4.5 to 93%) suggests marked variation between studies and likely between study arms. No study compared an intervention against a control group receiving no gastric lavage or provided any data to indicate whether a significant quantity of poison was removed. CONCLUSION Despite widespread use of multiple gastric lavages for OP pesticide poisoning across Asia, there is currently no high-quality evidence to support its clinical effectiveness.

Management of paraquat poisoning has remained mostly supportive and has been directed towards the modification of the toxicokinetics of the poison. Currently, there are no true pharmacological antagonists for paraquat and there are no chelating agents capable of binding the poison in the blood or other tissues. Recognizing the fact that paraquat induces its toxic effects via oxidative stress-mediated mechanisms, innovations in the management of paraquat poisoning are directed towards the use of antioxidants. In this review, the status of antioxidants in ameliorating or treating the toxic effects produced by paraquat is presented.", "title": "Role of antioxidants in paraquat toxicity." }, { "docid": "33203108", "text": "INTRODUCTION Paraquat is a commonly ingested poison especially in Southern India. There is no antidote for paraquat poison and consumption is often fatal. The usual cause of death is either acute lung injury or multi-organ failure. AIM To evaluate the role of early haemoperfusion as a therapy in paraquat poisoned patients. MATERIALS AND METHODS This study was a retrospective analysis of patients admitted to a Tertiary Medical College Hospital between January 2012 and December 2015 with history of paraquat consumption, comparing outcomes in those who received only gastric lavage and symptomatic treatment with those who received haemoperfusion as a therapy. The role of early haemoperfusion (≤ 6 hours) vs late haemoperfusion (> 6 hours) in paraquat poisoned patients was also compared. The data of these patients was extracted and analysed with respect to age, sex, mode of treatment, the outcome in patients who received early and late haemoperfusion. RESULTS A total of 101 patients were studied out of which 62 died. Deaths were more in those patients who received only gastric lavage with symptomatic treatment as therapy compared to those who received haemoperfusion i.e., 92.1% vs 42.9% respectively. We also found that, the survival rate was better in patients who received early haemoperfusion.

Treatment consisted of early digestive decontamination and hemodialysis, followed by antioxidant therapy, including the administration of deferoxamine (100 mg/kg in 24 h) and a continuous infusion of acetylcysteine (300 mg/kg/d during 3 weeks). The patient only developed a nonoliguric acute renal failure, a mild alteration of liver tests, and an impairment of CO transfer factor without any respiratory complaint. Renal and hepatic disturbances completely resolved within 1 month, whereas CO transfer factor remained altered 14 months later.

In many developing countries paraquat is widely available and inexpensive, making poisoning prevention difficult. However most of the people who become poisoned from paraquat have taken it as a means of suicide. Standard treatment for paraquat poisoning both prevents further absorption and reduces the load of paraquat in the blood through haemoperfusion or haemodialysis. The effectiveness of standard treatments is extremely limited. The immune system plays an important role in exacerbating paraquat-induced lung fibrosis. Immunosuppressive treatment using glucocorticoid and cyclophosphamide in combination is being developed and studied. OBJECTIVES To assess the effects of glucocorticoid with cyclophosphamide on mortality in patients with paraquat-induced lung fibrosis. SEARCH METHODS To identify randomised controlled trials (RCTs) on this topic, we searched the Cochrane Injuries Group's Specialised Register (searched 1 February 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 1), MEDLINE (Ovid SP) (1946 January Week 3 2012), EMBASE (Ovid SP) (1947 to Week 4 2012), ISI Web of Science: Science Citation Index Expanded (SCI-EXPANDED) (1970 to January 2012), ISI Web of Science: Conference Proceedings Citation Index - Science (CPCI-S) (1990 to January 2012), Chinese Biomedical Literature and Retrieval System (CBM) (1978 to April 2012), Chinese Medical Current Contents (CMCC) (1995 to April 2012), and Chinese Medical Academic Conference (CMAC) (1994 to April 2012). Searches were completed on English language databases on 1 February 2012 and on Chinese language databases on 12 April 2012. SELECTION CRITERIA RCTs were included in this review. All patients were to receive standard care, plus the intervention or control. The intervention was glucocorticoid with cyclophosphamide in combination versus a control of a placebo, standard care alone or any other therapy in addition to standard care. DATA COLLECTION AND ANALYSIS The mortality risk ratio (RR) and 95% confidence interval (CI) was calculated for each study on an intention-to-treat basis. Data for all-cause mortality at final follow-up were summarised in a meta-analysis using a fixed-effect model. MAIN RESULTS This systematic review includes three trials with a combined total of 164 participants who had moderate to severe paraquat poisoning. Patients who received glucocorticoid with cyclophosphamide in addition to standard care had a lower risk of death at final follow-up than those receiving standard care only (RR 0.72; 95% CI 0.59 to 0.89).

The aim of the present study was to compare the age and gender distribution of patients prescribed psychotropic drugs with patients attempting and completing suicide with these drugs. Data were obtained from the Australian census and studies of general practitioner prescribing, patients who committed suicide or presented with self-poisoning within a defined geographic area. The characteristics of these populations were compared to calculate odds ratios for attempting or completing suicide with psychotropic drugs, before and after correction for rates of prescription, in different age and gender groups. The odds ratios (ORs) for self-poisoning were higher for those aged less than 45 years and yet this group was least likely to be prescribed psychotropic drugs. Men had a much higher rate of completed suicide using more lethal methods. The ORs for self-poisoning and suicide with psychotropic drugs, after correction for prescription rates, for those aged 15 to 24 years were 11.1 and 1.7, respectively. Those aged 25 to 44 years had ORs of 4.9 and 4.3, and, by contrast, those over 75 years had ORs of 0.03 and 0. Women were slightly more likely to poison themselves with psychotropic drugs (OR 1.2).

Among 6458 diabetic patients, platelet GP IIb/IIIa inhibition was associated with a significant mortality reduction at 30 days, from 6.2% to 4.6% (OR 0.74; 95% CI 0.59 to 0.92; P=0.007).

We carried out an interrupted time-series analysis of prescribing and deaths (suicide, open verdicts, accidental poisonings) involving single analgesics. The reduction in prescribing of co-proxamol following its withdrawal in 2005 was accompanied by increases in prescribing of several other analgesics (co-codamol, paracetamol, codeine, co-dydramol, tramadol, oxycodone, and morphine) during 2005-2010 compared with 1998-2004. These changes were associated with major reductions in deaths due to poisoning with co-proxamol receiving verdicts of suicide and undetermined cause of -21 deaths (95% CI -34 to -8) per quarter, equating to approximately 500 fewer suicide deaths (-61%) over the 6 years 2005-2010, and -25 deaths (95% CI -38 to -12) per quarter, equating to 600 fewer deaths (-62%) when accidental poisoning deaths were included.

All patients received aspirin and were randomly assigned treatment with tirofiban or heparin. We took baseline measurements of troponin I and troponin T.

Prespecified analyses of the primary (cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke) and key secondary end points, including net clinical benefit (death, nonfatal myocardial infarction, nonfatal stroke, and nonfatal TIMI major bleeding) were compared by use of the log-rank test. We found that 3146 subjects had a preexisting history of DM, including 776 receiving insulin. The primary end point was reduced significantly with prasugrel among subjects without DM (9.2% versus 10.6%; hazard ratio [HR], 0.86; P=0.02) and with DM (12.2% versus 17.0%; HR, 0.70; P<0.001, P(interaction)=0.09).

Expression of a key group of these inducible proteins is controlled at the transcriptional level by the soxRS locus (the soxRS regulon). A two-stage control system was hypothesized for soxRS, in which an intracellular redox signal would trigger the SoxR protein as a transcriptional activator of the soxS gene and the resulting increased levels of SoxS protein would activate transcription of the various soxRS regulon genes (B. Demple and C.F. Amábile Cuevas, Cell 67:837-839, 1990). We have constructed operon fusions of the E. coli lac genes to the soxS promoter to monitor soxS transcription. Expression from the soxS promoter is strongly inducible by paraquat in a manner strictly dependent on a functional soxR gene. Several other superoxide-generating agents also trigger soxR(+)-dependent soxS expression, and the inductions by paraquat and phenazine methosulfate were dependent on the presence of oxygen. Numerous other oxidative stress agents (H2O2, gamma rays, heat shock, etc.) failed to induce soxS, while aerobic growth of superoxide dismutase-deficient bacteria triggered soxR-dependent soxS expression. These results indicate a specific redox signal for soxS induction. A direct role for SoxR protein in the activation of the soxS gene is indicated by band-shift and DNase I footprinting experiments that demonstrate specific binding of the SoxR protein in cell extracts to the soxS promoter.

Individuals homozygous for alpha(+)-thalassaemia have microcytosis and an increased erythrocyte count. Alpha(+)-thalassaemia homozygosity confers considerable protection against severe malaria, including severe malarial anaemia (SMA) (Hb concentration < 50 g/l), but does not influence parasite count. We tested the hypothesis that the erythrocyte indices associated with alpha(+)-thalassaemia homozygosity provide a haematological benefit during acute malaria. METHODS AND FINDINGS Data from children living on the north coast of Papua New Guinea who had participated in a case-control study of the protection afforded by alpha(+)-thalassaemia against severe malaria were reanalysed to assess the genotype-specific reduction in erythrocyte count and Hb levels associated with acute malarial disease. We observed a reduction in median erythrocyte count of approximately 1.5 x 10(12)/l in all children with acute falciparum malaria relative to values in community children (p < 0.001). We developed a simple mathematical model of the linear relationship between Hb concentration and erythrocyte count. This model predicted that children homozygous for alpha(+)-thalassaemia lose less Hb than children of normal genotype for a reduction in erythrocyte count of >1.1 x 10(12)/l as a result of the reduced mean cell Hb in homozygous alpha(+)-thalassaemia. In addition, children homozygous for alpha(+)-thalassaemia require a 10% greater reduction in erythrocyte count than children of normal genotype (p = 0.02) for Hb concentration to fall to 50 g/l, the cutoff for SMA. We estimated that the haematological profile in children homozygous for alpha(+)-thalassaemia reduces the risk of SMA during acute malaria compared to children of normal genotype (relative risk 0.52; 95% confidence interval [CI] 0.24-1.12, p = 0.09). CONCLUSIONS The increased erythrocyte count and microcytosis in children homozygous for alpha(+)-thalassaemia may contribute substantially to their protection against SMA. A lower concentration of Hb per erythrocyte and a larger population of erythrocytes may be a biologically advantageous strategy against the significant reduction in erythrocyte count that occurs during acute infection with the malaria parasite Plasmodium falciparum.

Subjects completed a 13-item quiz concerning their knowledge of food and nutrition before and after the presentation to determine its efficacy in teaching patients the material. RESULTS Fifty patients completed both the pre- and post-presentation tests. The mean percentage of correct answers on the pre-test was 85.6%, which rose to 89.3% on the post-test. This difference of 3.7% was statistically significant (t = 2.43, df = 49, p < 0.02), and the mean percent of improvement was 6.1%.

DESIGN AND SETTING Prospective, randomized, double-blind, placebo-controlled trial conducted from May 2000 to December 2001 at the Grantham Hospital at the University of Hong Kong. PARTICIPANTS Two hundred Chinese patients aged mean (SD) 68 (6.5) years with stable moderate renal insufficiency (creatinine clearance <60 mL/min [1.00 mL/s]) who were undergoing elective coronary angiography with or without intervention. INTERVENTION Participants were randomly assigned to receive oral acetylcysteine(600 mg twice per day; n = 102) or matching placebo tablets (n = 98) on the day before and the day of angiography. All patients received low-osmolality contrast agent. MAIN OUTCOME MEASURES Occurrence of more than a 25% increase in serum creatinine level within 48 hours after contrast administration; change in creatinine clearance and serum creatinine level. RESULTS Twelve control patients (12%) and 4 acetylcysteine patients (4%) developed a more than 25% increase in serum creatinine level within 48 hours after contrast administration (relative risk, 0.32; 95% confidence interval [CI], 0.10-0.96; P =.03). Serum creatinine was lower in the acetylcysteine group (1.22 mg/dL [107.8 micromol/L]; 95% CI, 1.11-1.33 mg/dL vs 1.38 mg/dL [122.9 micromol/L]; 95% CI, 1.27-1.49 mg/dL; P =.006) during the first 48 hours after angiography. Acetylcysteine treatment significantly increased creatinine clearance from 44.8 mL/min (0.75 mL/s) (95% CI, 42.7-47.6 mL/min) to 58.9 mL/min (0.98 mL/s) (95% CI, 55.6-62.3 mL/min) 2 days after the contrast administration (P<.001). The increase was not significant in the control group (from 42.1 to 44.1 mL/min [0.70 to 0.74 mL/s]; P =.15). The benefit of acetylcysteine was consistent among various patient subgroups and persistent for at least 7 days. There were no major treatment-related adverse events.

It arises from the endoderm as a dorsal and a ventral bud which fuse together to form the single organ. Mammals, birds, reptiles and amphibians have a pancreas with similar histology and mode of development, while in some fish, the islet cells are segregated as Brockmann bodies. Invertebrates do not have a pancreas, but comparable endocrine cells may be found in the gut or the brain. The early pancreatic bud shows uniform expression of the homeobox gene IPF-1 (also known as IDX-1, STF-1 or PDX), which when mutated to inactivity leads to total absence of the organ. The occurrence of heterotopic pancreas in the embryo, and also the metaplasias that can be displayed by a regenerating pancreas in the adult, both suggest that only a few gene products distinguish the pancreatic cell state from that of the surrounding tissues of duodenum, gall bladder and liver. In the developing pancreatic buds, the endocrine cells start to differentiate before the exocrine cells, and co-expression of different hormones by the same cell is often observed at early stages. Although pancreatic endocrine cells produce many gene products also characteristic of neurons, evidence from in vitro cultures and from quailchick grafts shows that they are of endogenous and not of neural crest origin. Observational studies suggest strongly that both endocrine and exocrine cells arise from the same endodermal rudiment. Development of the pancreas in embryonic life requires a trophic stimulus from the associated mesenchyme. In postnatal life, all cell types in the pancreas continue to grow. Destruction of acinar tissue by duct ligation or ethionine treatment is followed by rapid regeneration. Surgical removal of parts of the pancreas is followed by moderate but incomplete regeneration of both acini and islets. Poisoning with alloxan or streptozotocin can lead to permanent depletion of beta cells. Although the cell kinetics of the pancreas are not understood, it seems likely that there is a continuous slow turnover of cells, fed from a stem cells population in the ducts, and that the controls on the production rate of each cell type are local rather than systemic.", "title": "Developmental biology of the pancreas." }, { "docid": "22401061", "text": "The marginal costs and benefits of converting malaria programmes from a control to an elimination goal are central to strategic decisions, but empirical evidence is scarce.

Availability and magnitude of benefit on overall survival or quality of life determined at time of approval and after market entry. Validated European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) used to assess the clinical value of the reported gains in published studies of cancer drugs. Results From 2009 to 2013, the EMA approved the use of 48 cancer drugs for 68 indications. Of these, eight indications (12%) were approved on the basis of a single arm study. At the time of market approval, there was significant prolongation of survival in 24 of the 68 (35%).

Clinicians should understand the evidence but individualize decision making to the specific patient or situation. Similarly, the USPSTF notes that policy and coverage decisions involve considerations in addition to the evidence of clinical benefits and harms. Summary of Recommendation and Evidence The USPSTF recommends annual screening for lung cancer with low-dose computed tomography (LDCT) in adults aged 55 to 80 years who have a 30 pack-year smoking history and currently smoke or have quit within the past 15 years. Screening should be discontinued once a person has not smoked for 15 years or develops a health problem that substantially limits life expectancy or the ability or willingness to have curative lung surgery.

What the USPSTF Grades Mean and Suggestions for Practice Appendix Table 2. USPSTF Levels of Certainty Regarding Net Benefit Supplement. Consumer Fact Sheet. Rationale Importance Lung cancer is the third most common cancer and the leading cause of cancer-related death in the United States (1). The most important risk factor for lung cancer is smoking, which results in approximately 85% of all U.S. lung cancer cases (2). Although the prevalence of smoking has decreased, approximately 37% of U.S. adults are current or former smokers (2). The incidence of lung cancer increases with age and occurs most commonly in persons aged 55 years or older. Increasing age and cumulative exposure to tobacco smoke are the 2 most common risk factors for lung cancer. Lung cancer has a poor prognosis, and nearly 90% of persons with lung cancer die of the disease. However, early-stage nonsmall cell lung cancer (NSCLC) has a better prognosis and can be treated with surgical resection. Detection Most lung cancer cases are NSCLC, and most screening programs focus on the detection and treatment of early-stage NSCLC. Although chest radiography and sputum cytologic evaluation have been used to screen for lung cancer, LDCT has greater sensitivity for detecting early-stage cancer (3). Benefits of Detection and Early Treatment Although lung cancer screening is not an alternative to smoking cessation, the USPSTF found adequate evidence that annual screening for lung cancer with LDCT in a defined population of high-risk persons can prevent a substantial number of lung cancerrelated deaths. Direct evidence from a large, well-conducted, randomized, controlled trial (RCT) provides moderate certainty of the benefit of lung cancer screening with LDCT in this population (4). The magnitude of benefit to the person depends on that person's risk for lung cancer because those who are at highest risk are most likely to benefit. Screening cannot prevent most lung cancerrelated deaths, and smoking cessation remains essential. Harms of Detection and Early Intervention and Treatment The harms associated with LDCT screening include false-negative and false-positive results, incidental findings, overdiagnosis, and radiation exposure. False-positive LDCT results occur in a substantial proportion of screened persons; 95% of all positive results do not lead to a diagnosis of cancer. In a high-quality screening program, further imaging can resolve most false-positive results; however, some patients may require invasive procedures. The USPSTF found insufficient evidence on the harms associated with incidental findings. Overdiagnosis of lung cancer occurs, but its precise magnitude is uncertain. A modeling study performed for the USPSTF estimated that 10% to 12% of screen-detected cancer cases are overdiagnosedthat is, they would not have been detected in the patient's lifetime without screening. Radiation harms, including cancer resulting from cumulative exposure to radiation, vary depending on the age at the start of screening; the number of scans received; and the person's exposure to other sources of radiation, particularly other medical imaging. USPSTF Assessment The USPSTF concludes with moderate certainty that annual screening for lung cancer with LDCT is of moderate net benefit in asymptomatic persons who are at high risk for lung cancer based on age, total cumulative exposure to tobacco smoke, and years since quitting smoking. The moderate net benefit of screening depends on limiting screening to persons who are at high risk, the accuracy of image interpretation being similar to that found in the NLST (National Lung Screening Trial), and the resolution of most false-positive results without invasive procedures (4). Clinical Considerations Patient Population Under Consideration The risk for lung cancer increases with age and cumulative exposure to tobacco smoke and decreases with time since quitting smoking. The best evidence for the benefit of screening comes from the NLST, which enrolled adults aged 55 to 74 years who had at least a 30 pack-year smoking history and were current smokers or had quit within the past 15 years. As with all screening trials, the NLST tested a specific intervention over a finite period. Because initial eligibility extended through age 74 years and participants received 3 annual screening computed tomographic scans, the oldest participants in the trial were aged 77 years. The USPSTF used modeling studies to predict the benefits and harms of screening programs that use different screening intervals, age ranges, smoking histories, and times since quitting. A program that annually screens adults aged 55 to 80 years who have a 30 pack-year smoking history and currently smoke or have quit within the past 15 years is projected to have a reasonable balance of benefits and harms. The model assumes that persons who achieve 15 years of smoking cessation during the screening program discontinue screening. This model predicts the outcomes of continuing the screening program used in the NLST through age 80 years. Screening may not be appropriate for patients with substantial comorbid conditions, particularly those at the upper end of the screening age range. The NLST excluded persons who were unlikely to complete curative lung cancer surgery and those with medical conditions that posed a substantial risk for death during the 8-year trial. The baseline characteristics of the NLST showed a relatively healthy sample, and fewer than 10% of enrolled participants were older than 70 years (5). Persons with serious comorbid conditions may experience net harm, no net benefit, or at least substantially less net benefit. Similarly, persons who are unwilling to have curative lung surgery are unlikely to benefit from a screening program. Assessment of Risk Age, total exposure to tobacco smoke, and years since quitting smoking are important risk factors for lung cancer and were used to determine eligibility in the NLST. Other risk factors include specific occupational exposures, radon exposure, family history, and history of pulmonary fibrosis or chronic obstructive lung disease. The incidence of lung cancer is relatively low in persons younger than 50 years but increases with age, especially after age 60 years. In current and former smokers, age-specific incidence rates increase with age and cumulative exposure to tobacco smoke. Smoking cessation substantially reduces a person's risk for developing and dying of lung cancer. Among persons enrolled in the NLST, those who were at highest risk because of additional risk factors or a greater cumulative exposure to tobacco smoke experienced most of the benefit (6). A validated multivariate model showed that persons in the highest 60% of risk accounted for 88% of all deaths preventable by screening. Screening Tests Low-dose computed tomography has shown high sensitivity and acceptable specificity for the detection of lung cancer in high-risk persons. Chest radiography and sputum cytologic evaluation have not shown adequate sensitivity or specificity as screening tests. Therefore, LDCT is currently the only recommended screening test for lung cancer. Treatment Surgical resection is the current standard of care for localized NSCLC. This type of cancer is treated with surgical resection when possible and also with radiation and chemotherapy. Annual LDCT screening may not be useful for patients with life-limiting comorbid conditions or poor functional status who may not be candidates for surgery. Other Approaches to Prevention Smoking cessation is the most important intervention to prevent NSCLC. Advising smokers to stop smoking and preventing nonsmokers from being exposed to tobacco smoke are the most effective ways to decrease the morbidity and mortality associated with lung cancer. Current smokers should be informed of their continuing risk for lung cancer and offered cessation treatments. Screening with LDCT should be viewed as an adjunct to tobacco cessation interventions.

The Centers for Disease Control and Prevention has developed a Web site with many such resources, including information on tobacco quit lines, available in several languages (www.cdc.gov/tobacco/campaign/tips).

MUC1-C activates the NF-κB p65 signaling pathway by interacting with IκB kinase ß.

The MUC1 oncoprotein is aberrantly overexpressed by most human carcinomas and, similarly to NF-κB, blocks apoptosis and induces transformation. This study demonstrates that overexpression of MUC1 in human carcinoma cells is associated with constitutive activation of NF-κB p65. We show that MUC1 interacts with the high-molecular-weight IκB kinase (IKK) complex in vivo and that the MUC1 cytoplasmic domain binds directly to IKKβ and IKKγ. Interaction of MUC1 with both IKKβ and IKKγ is necessary for IKKβ activation, resulting in phosphorylation and degradation of IκBα. Studies in non-malignant epithelial cells show that MUC1 is recruited to the TNF-R1 complex and interacts with IKKβ–IKKγ in response to TNFα stimulation. TNFα-induced recruitment of MUC1 is dependent on TRADD and TRAF2, but not the death-domain kinase RIP1. In addition, MUC1-mediated activation of IKKβ is dependent on TAK1 and TAB2. These findings indicate that MUC1 is important for physiological activation of IKKβ and that overexpression of MUC1, as found in human cancers, confers sustained induction of the IKKβ–NF-κB p65 pathway.", "title": "MUC1 oncoprotein activates the IκB kinase β complex and constitutive NF-κB signalling" } ]

Here we show that IKKα is required for B cell maturation, formation of secondary lymphoid organs, increased expression of certain NF-κB target genes, and processing of the NF-κB2 (p100) precursor. IKKα preferentially phosphorylates NF-κB2, and this activity requires its phosphorylation by upstream kinases, one of which may be NF-κB–inducing kinase (NIK).

In the present study, we investigated whether ketamine inhibits release of high mobility group box 1 (HMGB1), a late-phase cytokine of sepsis, in lipopolysaccharide (LPS)-stimulated macrophages through heme oxygenase-1 (HO-1) induction. METHODS Macrophages were preincubated with various concentrations of ketamine and then treated with LPS (1 μg/mL). The cell culture supernatants were collected to measure inflammatory mediators (HMGB1, nitric oxide, tumor necrosis factor-α, and interleukin 1β) by enzyme-linked immunosorbent assay. Moreover, HO-1 protein expression, the phosphorylation and degradation of IκB-α, and the nuclear translocation of nuclear factor E2-related factor 2 and nuclear factor κB (NF-κB) p65 were tested by Western blot analysis. In addition, to further identify the role of HO-1 in this process, tin protoporphyrin (SnPP), an HO-1 inhibitor, was used. RESULTS Ketamine treatment dose-dependently attenuated the increased levels of proinflammatory mediators (HMGB1, nitric oxide, tumor necrosis factor α, and interleukin 1β) and increased the HO-1 protein expression in LPS-activated macrophages. Furthermore, ketamine suppressed the phosphorylation and degradation of IκB-α as well as the LPS-stimulated nuclear translocation of NF-κB p65 in macrophages. In addition, the present study also demonstrated that ketamine induced HO-1 expression through the nuclear translocation of nuclear factor E2-related factor 2 in macrophages. The effects of ketamine on LPS-induced proinflammatory cytokines production were partially reversed by the HO inhibitor tin protoporphyrin (SnPP).

METHODS Primary human chondrocytes were stimulated with AGEs in the presence or absence of neutralizing antibody against RAGE (anti-RAGE), MAPK specific inhibitors and PPARγ agonist pioglitazone. The expression of IL-1, MMP-13, TNF-α, PPARγ, nuclear NF-κB p65 and cytosol IκBα was determined by western blotting and real-time PCR. RESULTS AGEs could enhance the expression of IL-1, TNF-α, and MMP-13, but the level of PPARγ was decreased in a time- and dose-dependent manner, which was inhibited by anti-RAGE, SB203580 (P38 MAPK specific inhibitor) and SP600125 (a selective inhibitor of JNK).

PAR-2 expression was determined using real-time reverse transcription-polymerase chain reaction and protein levels by immunohistochemistry in normal and OA cartilage. Protein modulation was investigated in OA cartilage explants treated with a specific PAR-2-activating peptide (PAR-2-AP), SLIGKV-NH2 (1 to 400 μM), interleukin 1 beta (IL-1β) (100 pg/mL), tumor necrosis factor-alpha (TNF-α) (5 ng/mL), transforming growth factor-beta-1 (TGF-β1) (10 ng/mL), or the signalling pathway inhibitors of p38 (SB202190), MEK1/2 (mitogen-activated protein kinase kinase) (PD98059), and nuclear factor-kappa B (NF-κB) (SN50), and PAR-2 levels were determined by immunohistochemistry. Signalling pathways were analyzed on OA chondrocytes by Western blot using specific phospho-antibodies against extracellular signal-regulated kinase 1/2 (Erk1/2), p38, JNK (c-jun N-terminal kinase), and NF-κB in the presence or absence of the PAR-2-AP and/or IL-1β. PAR-2-induced MMP and COX-2 levels in cartilage were determined by immunohistochemistry. PAR-2 is produced by human chondrocytes and is significantly upregulated in OA compared with normal chondrocytes (p < 0.04 and p < 0.03, respectively). The receptor levels were significantly upregulated by IL-1β (p < 0.006) and TNF-α (p < 0.002) as well as by the PAR-2-AP at 10, 100, and 400 μM (p < 0.02) and were downregulated by the inhibition of p38.

METHODS We investigated the effects of gastric cancer cell-derived exosomes (GC-Ex) on the pro-tumor activation of neutrophils and elucidated the underlying mechanisms. RESULTS GC-Ex prolonged neutrophil survival and induced expression of inflammatory factors in neutrophils. GC-Ex-activated neutrophils, in turn, promoted gastric cancer cell migration. GC-Ex transported high mobility group box-1 (HMGB1) that activated NF-κB pathway through interaction with TLR4, resulting in an increased autophagic response in neutrophils. Blocking HMGB1/TLR4 interaction, NF-κB pathway, and autophagy reversed GC-Ex-induced neutrophil activation. Silencing HMGB1 in gastric cancer cells confirmed HMGB1 as a key factor for GC-Ex-mediated neutrophil activation. Furthermore, HMGB1 expression was upregulated in gastric cancer tissues.

The core Hippo components in mammals are composed of the upstream serine/threonine kinases Mst1/2, MAPK4Ks and Lats1/2. Inactivation of these upstream kinases leads to dephosphorylation, stabilization, nuclear translocation and thus activation of the major functional transducers of the Hippo pathway, YAP and its paralogue TAZ. YAP/TAZ are transcription co-activators that regulate gene expression primarily through interaction with the TEA domain DNA-binding family of transcription factors (TEAD). The current paradigm for regulation of this pathway centres on phosphorylation-dependent nucleocytoplasmic shuttling of YAP/TAZ through a complex network of upstream components. However, unlike other transcription factors, such as SMAD, NF-κB, NFAT and STAT, the regulation of TEAD nucleocytoplasmic shuttling has been largely overlooked. In the present study, we show that environmental stress promotes TEAD cytoplasmic translocation via p38 MAPK in a Hippo-independent manner. Importantly, stress-induced TEAD inhibition predominates YAP-activating signals and selectively suppresses YAP-driven cancer cell growth.

This Nef-induced priming of TCR signaling pathways occurred independently of calcium signaling and involved a very proximal step before protein kinase C activation. Engagement of the TCR by MHC-bound Ag triggers the formation of the immunological synapse by recruiting detergent-resistant membrane microdomains, termed lipid rafts. Approximately 5-10% of the total cellular pool of Nef is localized within lipid rafts. Using confocal and real-time microscopy, we found that Nef in lipid rafts was recruited into the immunological synapse within minutes after Ab engagement of the TCR/CD3 and CD28 receptors. This recruitment was dependent on the N-terminal domain of Nef encompassing its myristoylation. Nef did not increase the number of cell surface lipid rafts or immunological synapses. Recently, studies have shown a specific interaction of Nef with an active subpopulation of p21-activated kinase-2 found only in the lipid rafts.

Oxygen glucose deprivation was performed on bEND.3 cells to explore the mechanisms of metformin in inhibiting inflammatory signaling pathways. RESULTS Infarct volume was reduced in metformin-treated mice compared to the control group following tMCAO (P < 0.05). Neurobehavioral outcomes were greatly improved in metformin-treated mice (P < 0.05).

We have developed a combined experimental/computational framework to address this problem and used it to understand the genetic basis of ethanol tolerance in Escherichia coli. We used fitness profiling to measure the consequences of single-locus perturbations in the context of ethanol exposure. A module-level computational analysis was then used to reveal the organization of the contributing loci into cellular processes and regulatory pathways (e.g. osmoregulation and cell-wall biogenesis) whose modifications significantly affect ethanol tolerance. Strikingly, we discovered that a dominant component of adaptation involves metabolic rewiring that boosts intracellular ethanol degradation and assimilation. Through phenotypic and metabolomic analysis of laboratory-evolved ethanol-tolerant strains, we investigated naturally accessible pathways of ethanol tolerance. Remarkably, these laboratory-evolved strains, by and large, follow the same adaptive paths as inferred from our coarse-grained search of the fitness landscape.", "title": "Regulatory and metabolic rewiring during laboratory evolution of ethanol tolerance in E. coli" } ]

To gain insight into how E. coli responds to such hydrolysates, we studied an E. coli K-12 ethanologen fermenting a hydrolysate prepared from corn stover pretreated by ammonia fiber expansion. Despite the high sugar content (∼6% glucose, 3% xylose) and relatively low toxicity of this hydrolysate, E. coli ceased growth long before glucose was depleted. Nevertheless, the cells remained metabolically active and continued conversion of glucose to ethanol until all glucose was consumed. Gene expression profiling revealed complex and changing patterns of metabolic physiology and cellular stress responses during an exponential growth phase, a transition phase, and the glycolytically active stationary phase. During the exponential and transition phases, high cell maintenance and stress response costs were mitigated, in part, by free amino acids available in the hydrolysate. However, after the majority of amino acids were depleted, the cells entered stationary phase, and ATP derived from glucose fermentation was consumed entirely by the demands of cell maintenance in the hydrolysate. Comparative gene expression profiling and metabolic modeling of the ethanologen suggested that the high energetic cost of mitigating osmotic, lignotoxin, and ethanol stress collectively limits growth, sugar utilization rates, and ethanol yields in alkali-pretreated lignocellulosic hydrolysates.", "title": "Complex physiology and compound stress responses during fermentation of alkali-pretreated corn stover hydrolysate by an Escherichia coli ethanologen." }, { "docid": "24019260", "text": "Alcohol dependence is a disease that impacts millions of individuals worldwide.

We have investigated the role of varenicline in the modulation of ethanol consumption and seeking using three different animal models of drinking. We show that acute administration of varenicline, in doses reported to reduce nicotine reward, selectively reduced ethanol but not sucrose seeking using an operant self-administration drinking paradigm and also decreased voluntary ethanol but not water consumption in animals chronically exposed to ethanol for 2 months before varenicline treatment. Furthermore, chronic varenicline administration decreased ethanol consumption, which did not result in a rebound increase in ethanol intake when the varenicline was no longer administered. The data suggest that the alpha4beta2 nAChRs may play a role in ethanol-seeking behaviors in animals chronically exposed to ethanol.

A two-stage control system was hypothesized for soxRS, in which an intracellular redox signal would trigger the SoxR protein as a transcriptional activator of the soxS gene and the resulting increased levels of SoxS protein would activate transcription of the various soxRS regulon genes (B.

Expression from the soxS promoter is strongly inducible by paraquat in a manner strictly dependent on a functional soxR gene. Several other superoxide-generating agents also trigger soxR(+)-dependent soxS expression, and the inductions by paraquat and phenazine methosulfate were dependent on the presence of oxygen. Numerous other oxidative stress agents (H2O2, gamma rays, heat shock, etc.) failed to induce soxS, while aerobic growth of superoxide dismutase-deficient bacteria triggered soxR-dependent soxS expression.

MATERIALS/METHODS The preventive effect on hepatic lipid accumulation was estimated by using an oleic acid (OA)-induced NAFLD model in vitro and a Western diet (high-fat high-sucrose; WD)-induced obese mouse model. Animals were divided into three groups (n = 7): normal diet group (ND), WD group, and WD plus 1% EAF group. RESULTS EAF reduced OA-stimulated lipid accumulation in HepG2 cells in the absence of cellular cytotoxicity and significantly blocked transcriptional activation of sterol regulatory element-binding protein 1 and fatty acid synthase genes. Subsequently, we investigated these effects in vivo in mice fed either ND or WD in the presence or absence of EAF supplementation.

In this model, cancer cells induce oxidative stress in cancer-associated fibroblasts, which then acts as a \"metabolic\" and \"mutagenic\" motor to drive tumor-stroma co-evolution, DNA damage and aneuploidy in cancer cells. More specifically, we show that an acute loss of Cav-1 expression leads to mitochondrial dysfunction, oxidative stress and aerobic glycolysis in cancer associated fibroblasts. Also, we propose that defective mitochondria are removed from cancer-associated fibroblasts by autophagy/mitophagy that is induced by oxidative stress. As a consequence, cancer associated fibroblasts provide nutrients (such as lactate) to stimulate mitochondrial biogenesis and oxidative metabolism in adjacent cancer cells (the \"Reverse Warburg Effect\"). We provide evidence that oxidative stress in cancer-associated fibroblasts is sufficient to induce genomic instability in adjacent cancer cells, via a bystander effect, potentially increasing their aggressive behavior. Finally, we directly demonstrate that nitric oxide (NO) over-production, secondary to Cav-1 loss, is the root cause for mitochondrial dysfunction in cancer associated fibroblasts. In support of this notion, treatment with anti-oxidants (such as N-acetyl-cysteine, metformin and quercetin) or NO inhibitors (L-NAME) was sufficient to reverse many of the cancer-associated fibroblast phenotypes that we describe. Thus, cancer cells use \"oxidative stress\" in adjacent fibroblasts (i) as an \"engine\" to fuel their own survival via the stromal production of nutrients and (ii) to drive their own mutagenic evolution towards a more aggressive phenotype, by promoting genomic instability. We also present evidence that the \"field effect\" in cancer biology could also be related to the stromal production of ROS and NO species. eNOS-expressing fibroblasts have the ability to downregulate Cav-1 and induce mitochondrial dysfunction in adjacent fibroblasts that do not express eNOS.

Currently, Nrf2 is known to regulate the expression of hundreds of cytoprotective genes to counteract endogenously or exogenously generated oxidative stress. Furthermore, when activated in human tumors by somatic mutations, Nrf2 confers growth advantages and chemoresistance by regulating genes involved in various processes such as the pentose phosphate pathway and nucleotide synthesis in addition to antioxidant proteins. Interestingly, increasing evidence shows that Nrf2 is associated with mitochondrial biogenesis during environmental stresses in certain tissues such as the heart. Furthermore, SKN-1, a functional homolog of Nrf2 in C. elegans, is activated by mitochondrial reactive oxygen species and extends life span by promoting mitochondrial homeostasis (i.e., mitohormesis). Similarly, Nrf2 activation was recently observed in the heart of surfeit locus protein 1 (Surf1) -/- mice in which cellular respiration was decreased due to cytochrome c oxidase defects.

The impact of the SNS on the immune modulation of social defeat has not been examined. The following studies were designed to determine whether SNS activation during social disruption stress (SDR) influences anxiety-like behavior as well as the activation, priming, and glucocorticoid resistance of splenocytes after social stress. CD-1 mice were exposed to one, three, or six cycles of SDR and HPLC analysis of the plasma and spleen revealed an increase in catecholamines. After six cycles of SDR the open field test was used to measure behaviors characteristic of anxiety and indicated that the social defeat induced increase in anxiety-like behavior was blocked by pre-treatment with the β-adrenergic antagonist propranolol. Pre-treatment with the β-adrenergic antagonist propranolol did not significantly alter corticosterone levels indicating no difference in activation of the hypothalamic-pituitary-adrenal axis. In addition to anxiety-like behavior the SDR induced splenomegaly and increase in plasma IL-6, TNFα, and MCP-1 were each reversed by pre-treatment with propranolol. Furthermore, flow cytometric analysis of cells from propranolol pretreated mice reduced the SDR-induced increase in the percentage of CD11b(+) splenic macrophages and significantly decreased the expression of TLR2, TLR4, and CD86 on the surface of these cells. In addition, supernatants from 18h LPS-stimulated ex vivo cultures of splenocytes from propranolol-treated SDR mice contained less IL-6. Likewise propranolol pre-treatment abrogated the glucocorticoid insensitivity of CD11b(+) cells ex vivo when compared to splenocytes from SDR vehicle-treated mice.

More importantly, KLF2 attenuated gram-positive endotoxins induced cellular motility and proinflammatory gene expression in myeloid cells. Consistent with these results, mice deficient in myeloid HIF-1α were protected from gram-positive endotoxin-induced sepsis mortality and clinical symptomatology.

This 64 kDa protein, encoded by svpA, is both secreted in culture supernatants and surface-exposed, as shown by immunogold labelling of whole bacteria with an anti-SvpA antibody. Analysis of the peptide sequence revealed that SvpA contains a leader peptide, a predicted C-terminal transmembrane region and a positively charged tail resembling that of the surface protein ActA, suggesting that SvpA might partially reassociate with the bacterial surface by its C-terminal membrane anchor. An allelic mutant was constructed by disrupting svpA in the wild-type strain LO28. The virulence of this mutant was strongly attenuated in the mouse, with a 2 log decrease in the LD50 and restricted bacterial growth in organs as compared to the wild-type strain. This reduced virulence was not related either to a loss of adherence or to a lower expression of known virulence factors, which remained unaffected in the svpA mutant. It was caused by a restriction of intracellular growth of mutant bacteria. By following the intracellular behaviour of bacteria within bone-marrow-derived macrophages by confocal and electron microscopy studies, it was found that most svpA mutant bacteria remained confined within phagosomes, in contrast to wild-type bacteria which rapidly escaped to the cytoplasm. The regulation of svpA was independent of PrfA, the transcriptional activator of virulence genes in L. monocytogenes. In fact, SvpA was down-regulated by MecA, ClpC and ClpP, which are highly homologous to proteins of Bacillus subtilis forming a regulatory complex controlling the competence state of this saprophyte. The results indicate that: (i) SvpA is a novel factor involved in the virulence of L. monocytogenes, promoting bacterial escape from phagosomes of macrophages; (ii) SvpA is, at least partially, associated with the surface of bacteria; and (iii) SvpA is PrfA-independent and controlled by a MecA-dependent regulatory network.", "title": "SvpA, a novel surface virulence-associated protein required for intracellular survival of Listeria monocytogenes." }, { "docid": "9194077", "text": "Pathogenesis of Alzheimer’s disease (AD), which is characterised by accumulation of extracellular deposits of β-amyloid peptide (Aβ) in the brain, has recently been linked to vascular disorders such as ischemia and stroke.

Chronic oxidative stress has numerous pathological consequences including cancer, arthritis and neurodegenerative disease. Glutathione-associated metabolism is a major mechanism for cellular protection against agents which generate oxidative stress. It is becoming increasingly apparent that the glutathione tripeptide is central to a complex multifaceted detoxification system, where there is substantial inter-dependence between separate component members. Glutathione participates in detoxification at several different levels, and may scavenge free radicals, reduce peroxides or be conjugated with electrophilic compounds. Thus, glutathione provides the cell with multiple defences not only against ROS but also against their toxic products. This article discusses how glutathione biosynthesis, glutathione peroxidases, glutathione S-transferases and glutathione S-conjugate efflux pumps function in an integrated fashion to allow cellular adaption to oxidative stress. Co-ordination of this response is achieved, at least in part, through the antioxidant responsive element (ARE) which is found in the promoters of many of the genes that are inducible by oxidative and chemical stress. Transcriptional activation through this enhancer appears to be mediated by basic leucine zipper transcription factors such as Nrf and small Maf proteins. The nature of the intracellular sensor(s) for ROS and thiol-active chemicals which induce genes through the ARE is described. Gene activation through the ARE appears to account for the enhanced antioxidant and detoxification capacity of normal cells effected by many cancer chemopreventive agents. In certain instances it may also account for acquired resistance of tumours to cancer chemotherapeutic drugs.

Recognition of the condition is important as dietary adjustments reduce the excretion of trimethylamine and may reduce the odour. Occasionally, a short course of metronidazole, neomycin and lactulose may suppress production of trimethylamine by reducing the activity of gut microflora.

Whole body skeletal survey (WBSS), Magnetic resonance (MR) and 18F-FDG PET/CT are imaging techniques routinely used for the evaluation of bone involvement in MM patients. Aim As MM bone lesions may present low 18F-FDG uptake; the aim of this study was to assess the possible added value and limitations of 11C-Choline to that of 18F-FDG PET/CT in patients affected with MM. Methods Ten patients affected with MM underwent a standard 11C-Choline PET/CT and an 18F-FDG PET/CT within one week. The results of the two scans were compared in terms of number, sites and SUVmax of lesions. Results Four patients (40%) had a negative concordant 11C-Choline and 18F-FDG PET/CT scans. Two patients (20%) had a positive 11C-Choline and 18F-FDG PET/CT scans that identified the same number and sites of bone lesions. The remaining four patients (40%) had a positive 11C-Choline and 18F-FDG PET/CT scan, but the two exams identified different number of lesions. Choline showed a mean SUVmax of 5 while FDG showed a mean SUVmax of 3.8 (P = 0.042). Overall, 11C-Choline PET/CT scans detected 37 bone lesions and 18F-FDG PET/CT scans detected 22 bone lesions but the difference was not significant (P = 0.8). Conclusion According to these preliminary data, 11C-Choline PET/CT appears to be more sensitive than 18F-FDG PET/CT for the detection of bony myelomatous lesions. If these data are confirmed in larger series of patients, 11C-Choline may be considered a more appropriate functional imaging in association with MRI for MM bone staging.", "title": "11C-choline vs. 18F-FDG PET/CT in assessing bone involvement in patients with multiple myeloma" }, { "docid": "MED-3785", "text": "PURPOSE: Components of one-carbon metabolism are believed to influence cancer development with suggested mechanisms, including DNA methylation and DNA repair mechanisms. However, few prospective studies have investigated one-carbon metabolism in relation to prostate cancer risk, and the results have been conflicting. The aim of this study was to do a comprehensive investigation of the components of one-carbon metabolism in relation to prostate cancer risk. A panel of seven circulating B vitamins and related metabolites was selected, most of which have not been studied before. MATERIALS AND METHODS: We analyzed plasma concentrations of betaine, choline, cysteine, methionine, methylmalonic acid (MMA), vitamin B2, and vitamin B6 in 561 cases and 1,034 controls matched for age and recruitment date, nested within the population-based Northern Sweden Health and Disease Cohort. Relative risks of prostate cancer were estimated by conditional logistic regression. RESULTS: Positive associations with prostate cancer risk were observed for choline and vitamin B2, and an inverse association was observed for MMA. The relative risks for a doubling in concentrations were 1.46 [95% confidence interval (95% CI), 1.04-2.05; P(trend) = 0.03] for choline, 1.11 (95% CI, 1.00-1.23; P(trend) = 0.04) for vitamin B2, and 0.78 (95% CI, 0.63-0.97; P(trend) = 0.03) for MMA. Concentrations of betaine, cysteine, methionine, and vitamin B6 were not associated with prostate cancer risk. CONCLUSION: The results of this large prospective study suggest that elevated plasma concentrations of choline and vitamin B2 may be associated with an increased risk of prostate cancer.

We therefore assessed total plaque area (TPA) in patients attending Canadian vascular prevention clinics to determine if the atherosclerosis burden, as a marker of arterial damage, was related to egg intake. To provide perspective on the magnitude of the effect, we also analysed the effect of smoking (pack-years). METHODS: Consecutive patients attending vascular prevention clinics at University Hospital had baseline measurement of TPA by duplex ultrasound, and filled out questionnaires regarding their lifestyle and medications, including pack-years of smoking, and the number of egg yolks consumed per week times the number of years consumed (egg-yolk years). RESULTS: Data were available in 1262 patients; mean (SD) age was 61.5 (14.8) years; 47% were women. Carotid plaque area increased linearly with age after age 40, but increased exponentially with pack-years of smoking and with egg-yolk years. Plaque area in patients consuming <2 eggs per week (n = 388) was 125 ± 129 mm(2), versus 132 ± 142 mm(2) in those consuming 3 or more eggs per week (n = 603); (p < 0.0001 after adjustment for age). In multiple regression, egg-yolk years remained significant after adjusting for coronary risk factors.

Economic constraints, sociocultural limitations, insufficient dietary intake, and poor absorption leading to depleted vitamin A stores in the body have been regarded as potential determinants of the prevalence of VAD in South Asian developing countries. VAD is exacerbated by lack of education, poor sanitation, absence of new legislation and enforcement of existing food laws, and week monitoring and surveillance system. Several recent estimates confirmed higher morbidly and mortality rate among children and pregnant and non-pregnant women of childbearing age. Xerophthalmia is the leading cause of preventable childhood blindness with its earliest manifestations as night blindness and Bitot's spots, followed by blinding keratomalacia, all of which are the ocular manifestations of VAD. Children need additional vitamin A because they do not consume enough in their normal diet. There are three general ways for improving vitamin A status: supplementation, fortification, and dietary diversification. These approaches have not solved the problem in South Asian countries to the desired extent because of poor governmental support and supervision of vitamin A supplementation twice a year. An extensive review of the extant literature was carried out, and the data under various sections were identified by using a computerized bibliographic search via PubMed, Web of Science, and Google Scholar. All abstracts and full-text articles were examined, and the most relevant articles were selected for screening and inclusion in this review. Conclusively, high prevalence of VAD in South Asian developing countries leads to increased morbidity and mortality among infants, children, and pregnant women.

The investigation was single blind and prospective, and parents were given the option of volunteering to join the 'experiment' group, avoiding eggs, milk and their products for eight weeks, or the 'control' group, who consumed their customary food.

There is a focus in many countries to reduce the level of human illness from food-borne pathogens. Reduction of the prevalence of contaminated poultry meat or eggs is one major area of focus. The other is risk communication to the consumer, where information aimed at changing the food preparation behaviour has been utilised as a risk management tool. The efficacy of messages such as 'cook poultry meat and eggs thoroughly' or 'wash your hands' will depend both on the ability to change consumer behaviour as well as where the risk can best be mitigated. In order to prioritise what message should be given to the consumer, the relative contribution of different exposure pathways finally leading to ingestion of the pathogens and resulting in illness needs to be known. It is important to know whether cross-contamination events or undercooking are the greatest risk lurking in consumers' kitchens. A review of studies looking at the location of pathogens in food products has been performed and data regarding internal and external (surface) contamination of poultry meat with Salmonella spp. and Campylobacter jejuni and C. coli is presented.

It is increasingly believed that consumption of dietary cholesterol and egg yolks is harmless. There are good reasons for long-standing recommendations that dietary cholesterol should be limited to less than 200 mg/day; a single large egg yolk contains approximately 275 mg of cholesterol (more than a day’s worth of cholesterol). Although some studies showed no harm from consumption of eggs in healthy people, this outcome may have been due to lack of power to detect clinically relevant increases in a low-risk population. Moreover, the same studies showed that among participants who became diabetic during observation, consumption of one egg a day doubled their risk compared with less than one egg a week. Diet is not just about fasting cholesterol; it is mainly about the postprandial effects of cholesterol, saturated fats, oxidative stress and inflammation. A misplaced focus on fasting lipids obscures three key issues. Dietary cholesterol increases the susceptibility of low-density lipoprotein to oxidation, increases postprandial lipemia and potentiates the adverse effects of dietary saturated fat. Dietary cholesterol, including egg yolks, is harmful to the arteries. Patients at risk of cardiovascular disease should limit their intake of cholesterol. Stopping the consumption of egg yolks after a stroke or myocardial infarction would be like quitting smoking after a diagnosis of lung cancer: a necessary action, but late. The evidence presented in the current review suggests that the widespread perception among the public and health care professionals that dietary cholesterol is benign is misplaced, and that improved education is needed to correct this misconception. Résumé Une idée fausse et généralisée se répand au sein du public canadien et des médecins, qui pensent de plus en plus que la consommation de cholestérol alimentaire et de jaunes d’œuf est inoffensive. Les recommandations de longue date qui préconisent de limiter le cholestérol alimentaire à moins de 200 mg/jour reposent sur de bonnes raisons. Un seul gros jaune d’œuf contient environ 275 mg de cholestérol (plus que la portion quotidienne de cholestérol). Même si certaines études ont démontré que la consommation d’œufs n’est pas nuisible chez les personnes en santé, ce résultat peut découler de l’absence de capacité à déceler des augmentations pertinentes sur le plan clinique au sein d’une population à faible risque. De plus, les mêmes études ont révélé que chez les participants devenus diabétiques pendant la période d’observation, la consommation d’un œuf par jour doublait leur risque par rapport à la consommation de moins d’un œuf par semaine. Le régime ne vise pas à éviter le cholestérol, mais surtout les effets postprandiaux du cholestérol, des gras saturés, du stress oxydant et de l’inflammation. Le fait de se concentrer à tort sur les lipides à jeun occulte trois enjeux. Le cholestérol alimentaire accroît la susceptibilité des lipoprotéines à faible densité à l’oxydation, accroît la lipémie postprandiale et potentialise les effets secondaires des graisses saturées alimentaires. Le cholestérol alimentaire, y compris les jaunes d’œuf, est nuisible pour les artères. Les patients vulnérables aux maladies cardiovasculaires devraient limiter leur consommation de cholestérol. Le fait d’arrêter de consommer des jaunes d’œuf après un accident vasculaire cérébral ou un infarctus du myocarde s’apparenterait à arrêter de fumer après un diagnostic de cancer du poumon : c’est un geste nécessaire, mais entrepris tardivement.

Methods: A review and analysis of empirical and historical evidence pertaining to tobacco and food industry practices, messages, and strategies to influence public opinion, legislation and regulation, litigation, and the conduct of science. Findings: The tobacco industry had a playbook, a script, that emphasized personal responsibility, paying scientists who delivered research that instilled doubt, criticizing the “junk” science that found harms associated with smoking, making self-regulatory pledges, lobbying with massive resources to stifle government action, introducing “safer” products, and simultaneously manipulating and denying both the addictive nature of their products and their marketing to children. The script of the food industry is both similar to and different from the tobacco industry script. Conclusions: Food is obviously different from tobacco, and the food industry differs from tobacco companies in important ways, but there also are significant similarities in the actions that these industries have taken in response to concern that their products cause harm.

[ { "docid": "435940", "text": "You have to balance several concerns here. The primary problem is that if you go to the effort of saving your money you want to also be sure that your savings will not lose too much of its value to inflation. Ukraine had a terrible inflation spike in 2015 for obvious reasons. Even as inflation has settled down in 2016, it is stabilizing around 12% which is very high Exchange rates are your next concern. If you lose a large percentage of the value of your money just in the process of exchanging it, that also eats away at the value of your money. If you accept the US Federal Reserve target of 2% inflation, then you should only exchange money that you will hold long enough that both exchange fees will outweigh the 10% inflation advantage. Even in cases where you have placed your money in a foreign currency, there's a chance that your government could freeze accounts denominated in foreign currencies, so there's always the political risk that you have to factor in. For that reason keeping foreign currency in cash also has some appeal because it cannot be confiscated as easily. You could still certainly be robbed, so keeping all of your savings in cash isn't a great solution either. All in all, you are diversifying your savings if you use the strategy of balancing all three methods. Splitting it evenly to 5% for each method isn't the most important. I would suggest taking advantage of good exchange rates (as they appear) to time when you buy foreign currency.", "title": "" }, { "docid": "466950", "text": "\"Having savings only in your home currency is relatively 'low risk' compared with other types of 'low diversification'. This is because, in a simple case, your future cash outflows will be in your home currency, so if the GBP fluctuates in value, it will (theoretically) still buy you the same goods at home. In this way, keeping your savings in the same currency as your future expenditures creates a natural hedge against currency fluctuation. This gets complicated for goods imported from other countries, where base price fluctuates based on a foreign currency, or for situations where you expect to incur significant foreign currency expenditures (retirement elsewhere, etc.). In such cases, you no longer have certainty that your future expenditures will be based on the GBP, and saving money in other currencies may make more sense. In many circumstances, 'diversification' of the currency of your savings may actually increase your risk, not decrease it. Be sure you are doing this for a specific reason, with a specific strategy, and not just to generally 'spread your money around'. Even in case of a Brexit, consider: what would you do with a bank account full of USD? If the answer is \"\"Convert it back to GBP when needed (in 6 months, 5 years, 30, etc.), to buy British goods\"\", then I wouldn't call this a way to reduce your risk. Instead, I would call it a type of investment, with its own set of risks associated.\"", "title": "" }, { "docid": "21055", "text": "\"&gt; We've been deficit spending for generations and we're trillions in the hole, and that's the psychological issue hanging over our heads. Let's unpack that a bit. What does \"\"trillions in the hole\"\" actually mean for the *issuer* of the dollar? It means that the issuer at various points has to redeem its own interest-bearing dollars (treasuries) for its own non-interest bearing dollars (reserves/notes/coins). That's not a hole. That's moving a balance from the savings account to the checking account at the same bank. You don't think of your savings account balance as the bank being \"\"in the hole\"\" for checking account balances. You implicitly understand that the bank simply marks down the number in one account and marks up the number in the other and you don't fret that the bank might \"\"run out\"\" of checking account balances. Treasuries have this same relationship to reserves. Not similar, not analogous to but the same. Treasury securities are literally interest-bearing accounts at the federal reserve. Reserves are literally demand accounts at the federal reserve. When a treasury matures, a treasury securities account is marked down, a reserve account is marked up. When a treasury is issued, a treasury securities account is marked up and a reserve account is marked down. What you're thinking of as trillions \"\"in the hole\"\" is just trillions in a savings account balance. That's what it means to have \"\"debt\"\" in a currency that you are the *issuer* of and why foreign-denominated debt is fundamentally different. &gt;so we can design a system that will keep inflation low while we dump money into the economy We already have that. There's no inflation monster under the bed. If there's an inflation problem it's that we're so paranoid about it we're not putting *enough* money into the economy and so inflicting unnecessary misery on ourselves. &gt; the issue in my mind with dumping money while the debt situation is such a concern, is that speculators could sh*t the bed and devalue our currency There's nothing a speculator can do vs a sovereign currency that the issuing central bank can't offset. So if you are a sovereign and the issuing central bank is within and beneath your authority, you have the last word and there's no such thing as bond vigilantes. In contrast, if you take on sovereign obligations denominated in currencies where the issuing central bank sits outside your authority as is the case when you borrow/peg to foreign currency or enter a monetary union like the euro, you become just another currency user. Here, your government actually is kinda like a household and can go broke *in that foreign currency*. Consider how that perspective sheds light on the \"\"mystery\"\" of why some countries actually experience a debt crisis and others don't.

Know about fees :- When you use a debit card or credit card in a foreign country, there are generally two types of transaction fees that may apply: Understand exchange rates :- The exchange rate lets you know the amount of nearby money you can get for each U.S. dollar, missing any expenses. There are \"\"sell\"\" rates for individuals who are trading U.S. dollars for foreign currency, and, the other way around, \"\"purchase\"\" rates. It's a smart thought to recognize what the neighborhood money is worth in dollars so you can comprehend the estimation of your buys abroad. Sites like X-Rates offer a currency converter that gives the current exchange rate, so you can make speedy comparisons. You can utilize it to get a feel for how much certain amount (say $1, $10, $25, $50, $100) are worth in local currency. Remember that rates fluctuate, so you will be unable to suspect precisely the amount of a buy made in a foreign currency will cost you in U.S. dollars. To get cash, check for buddy banks abroad:- If you already have an account with a large bank or credit union in the U.S., you may have an advantage. Being a client of a big financial institution with a large ATM system may make it easier to find a subsidiary cash machine and stay away from an out-of-system charge. Bank of America, for example, is a part of the Global ATM Alliance, which lets clients of taking an interest banks use their debit cards to withdraw money at any Alliance ATM without paying the machine's operator an access fee, in spite of the fact that you may at present be charged for converting dollars into local currency used for purchases. Citibank is another well known bank for travelers because it has 45,000 ATMs in more than 30 countries, including popular study-abroad destinations such as the U.K., Italy and Spain. ATMs in a foreign country may allow withdrawals just from a financial records, and not from savings so make sure to keep an adequate checking balance. Also, ATM withdrawal limits will apply just as they do in the U.S., but the amount may vary based on the local currency and exchange rates. Weigh the benefits of other banks :- For general needs, online banks and even foreign banks can also be good options. With online banks, you don’t have to visit physical branches, and these institutions typically have lower fees. Use our checking account tool to find one that’s a good fit. Foreign banks:- Many American debit cards may not work in Europe, Asia and Latin America, especially those that don’t have an EMV chip that help prevent fraud. Or some cards may work at one ATM, but not another. One option for students who expect a more extended stay in a foreign country is to open a new account at a local bank. This will let you have better access to ATMs, and to make purchases more easily and without as many fees. See our chart below for the names of the largest banks in several countries. Guard against fraud and identity theft:- One of the most important things you can do as you plan your trip is to let your bank know that you’ll be abroad. Include exact countries and dates, when possible, to avoid having your card flagged for fraud. Unfortunately, incidents may still arise despite providing ample warning to your bank. Bring a backup credit card or debit card so you can still access some sort of money in case one is canceled. Passports are also critical — not just for traveling from place to place, but also as identification to open a bank account and for everyday purposes.

The short answer is yes; HSBC, for instance, based in New York, is listed on both the LSE and NYSE. Toyota's listed on the TSE and NYSE. There are many ways to do this; both of the above examples are the result of a corporation owning a subsidiary in a foreign country by the same name (a holding company), which sells its own stock on the local market. The home corporation owns the majority holdings of the subsidiary, and issues its own stock on its \"\"home country's\"\" exchange. It is also possible for the same company to list shares of the same \"\"pool\"\" of stock on two different exchanges (the foreign exchange usually lists the stock in the corporation's home currency and the share prices are near-identical), or for a company to sell different portions of itself on different exchanges.

This makes you more resilient to whatever the future may throw at you - a lower paying job, for instance, or high inflation that eats away at the value of your income. If you get a mortgage, then make sure to get a fixed interest rate. In this case, it protects you somewhat from high inflation because your mortgage payment stays the same, while what you would have had to pay in rent keeps going up an up. In both cases there is also taxes and insurance, of course. And those would go up with inflation. Finally, do make sure to purchase sensibly. A good rule of thumb on how much you can afford to pay for a home is 2.5x - 3.5x your annual income. I do realize that there are some areas where it's common for people to buy homes at a far greater multiple, but that doesn't mean it's a sensible thing to do.

That's true, but *how* does that come about? The effect on buying power stems from the level of spending in the present period. Too little leaves you anywhere from outright deflation and contraction to weaker growth falling short of capacity. Too much reaches capacity and keeps spending, bidding up prices and driving down purchasing power. It has nothing to do with debt:GDP or interest payments. &gt; Germany managed to skate by by creating a new Deutschmark in a confidence trick, and it worked because Germany is a solid, iron clad manufacturing powerhouse of a lot of stuff. There are two important differences between inter-war Germany and the US. First is that inter-war Germany *lost a war*. This real shock is kind of important. When you're talking about buying power of money, one side of it is the amount of money in circulation but the other side of it is how much real output there is to buy and German real output capacity collapsed after the war. Their most productive regions were occupied territory and they were no longer a powerhouse manufacturing a lot of stuff, driving down the value of their currency. So lesson number one from Germany: real output collapse harms your currency. The second problem is that losing a war left Germany saddled with war reparations denominated in foreign currency. When you're on the hook for something you don't print you're in a situation where you can run out of money and that's exactly what happened to them. They tried printing more of their own currency to buy the foreign stuff with but that quickly drove down the value of German currency. So lesson number two from Germany is you don't want to be on the hook for a currency you don't issue. Put the two together and you have a real supply shock + foreign-denominated debt eviscerating the buying power of German currency. It wasn't debt:GDP but the real basis for their economy collapsing out from under them pushed along by a need for foreign currency. &gt;My question is, at what point do we engage Washington's unlimited money printing presses until we reach that point? In answer to your question, the printing presses are what funds the real economy. The worry in terms of avoiding \"\"that point\"\" is in making sure we keep that real economy productive and fully funded. Ironically, taking our eye off the ball to focus on budget balance at the expense of real output pushes the economy in the direction you're afraid of going.

Risk is a very large component of the price that a saver will accept to deposit their money in a bank but not the only one. Essentially you are \"\"lending\"\" deposited cash to the bank that you put it in and they will lend it out at a certain risk to themselves and a certain risk to you. By diversifying who they lend to (corporations, home-buyers each other etc.) the banks mitigate a lot of the risk but lending to the bank is still a risky endeavour for the \"\"saver\"\" and the saver accepts a given interest rate for the amount of risk there is in having the money in that particular bank. The bank is also unable to diversify away all possible risk, but tries to do the best job it can. If a bank is seen to take bigger risks and therefore be in greater risk of failing (having a run on deposits) it must have a requisitely higher interest rates on deposits compared to a lower risk bank. \"\"Savers\"\" therefore \"\"shop around\"\" for the best interest rate for a given level of risk which sets the viable interest rate for that bank; any higher and the bank would not make a profit on the money that it lends out and so would not be viable as a business, any lower and savers would not deposit their money as the risk would be too high for the reward. Hence competition (or lack of it) will set the rate as a trade off between risk and return. Note that governments are also customers of the banking industry when they are issuing fixed income securities (bonds) and a good deal of the lending done by any bank is to various governments so the price that they borrow money at is a key determinant of what interest rate the bank can afford to give and are part of the competitive banking industry whether they want to be or not. Since governments in most (westernised) countries provide insurance for deposits the basic level of (perceived) risk for all of the banks in any given country is about the same. That these banks lend to each other on an incredibly regular basis (look into the overnight or repo money market if you want to see exactly how much, the rates that these banks pay to and receive from each other are governed by interbank lending rates called Libor and Euribor and are even more complicated than this answer) simply compounds this effect because it makes all of the banks reliant on each other and therefore they help each other to stay liquid (to some extent). Note that I haven't mentioned currency at all so far but this market in every country applies over a number of currencies. The way that this occurs is due to arbitrage; if I can put foreign money into a bank in a country at a rate that is higher than the rate in its native country after exchange costs and exchange rate risk I will convert all of my money to that currency and take the higher interest rate. For an ordinary individual's savings that is not really possible but remember that the large multinational banks can do exactly the same thing with billions of dollars of deposits and effectively get free money. This means that either the bank's interest rate will fall to a risk adjusted level or the exchange rate will move. Either of those moves will remove the potential for making money for nothing. In this case, therefore it is both the exchange rate risk (and costs) as well as the loan market in that country that set the interest rate in foreign currencies. Demand for loans in the foreign currency is not a major mover for the same reason. Companies importing from foreign entities need cash in foreign currencies to pay their bills and so will borrow money in other currencies to fulfil these operations which could come from deposits in the foreign currency if they were available at a lower interest rate than a loan in local currency plus the costs of exchange but the banks will be unwilling to loan to them for less than the highest return that they can get so will push up interest rates to their risk level in the same way that they did in the market before currencies were taken into account. Freedom of movement of foreign currencies, however, does move interest rates in foreign currencies as the banks want to be able to lend as much of currencies that are not freely deliverable as they can so will pay a premium for these currencies. Other political moves such as the government wanting to borrow large amounts of foreign currency etc. will also move the interest rate given for foreign currencies not just because loaning to the government is less risky but also because they sometimes pay a premium (in interest) for being able to borrow foreign currency which may balance this out. Speculation that a country may change its base interest rate will move short term rates, and can move long term rates if it is seen to be a part of a country's economic strategy. The theory behind this is deep and involved but the tl;dr answer would be the standard \"\"invisible hand\"\" response when anything market or arbitrage related is involved. references: I work in credit risk and got a colleague who is also a credit risk consultant and economist to look over it.

This is, in fact, one of the main jobs of the central bank for a currency; to manage the money supply, which in most fiat systems involves slowly increasing the amount of money to keep the economy growing (if there isn't enough money moving around in the economy it's reflected in a slowdown in GDP growth), while controlling inflation (the devaluation of a unit of currency with respect to most or all things that unit will buy including other currencies). Inflation's primary cause is defined quite simply as \"\"too many dollars chasing too few goods\"\". When demand is low for cash (because you have a lot of it) while demand for goods is high, the suppliers of those goods will increase their price for the goods (because people are willing to pay that higher price) and will also produce more. With quantitative easing, the central bank is increasing the money supply by several percentage points of GDP, much higher than is normally needed. This normally would cause the two things you mentioned: Inflation - inflation's primary cause is \"\"too many dollars chasing too few goods\"\"; when money is easy to get and various types of goods and services are not, people \"\"bid up\"\" the price on these things to get them (this usually happens when sellers see high demand for a product and increase the price to take advantage and to prevent a shortage). This often happens across the board in a situation like this, but there are certain key drivers that can cause other prices to increase (things like the price of oil, which affects transportation costs and thus the price to have anything shipped anywhere, whether it be the raw materials you need or the finished product you're selling). With the injection of so much money into the economy, rampant inflation would normally be the result. However, there are other variables at play in this particular situation. Chief among them is that no matter how much cash is in the economy, most of it is being sat on, in the form of cash or other \"\"safe havens\"\" like durable commodities (gold) and T-debt. So, most of the money the Fed is injecting into the economy is not chasing goods; it's repaying debt, replenishing savings and generally being hoarded by consumers and institutions as a hedge against the poor economy. In addition, despite how many dollars are in the economy right now, those dollars are in high demand all around the world to buy Treasury debt (one of the biggest safe havens in the global market right now, so much so that buying T-debt is considered \"\"saving\"\"). This is why the yields on Treasury bonds and notes are at historic lows; it's bad everywhere, and U.S. Government debt is one of the surest things in the world market, especially now that Euro-bonds have become suspect. Currency Devaluation - This is basically specialized inflation; when there are more dollars in the market than people want to have in order to use to buy our goods and services, demand for our currency (the medium of trade for our goods and services) drops, and it takes fewer Euros, Yen or Yuan to buy a dollar. This can happen even if demand for our dollars inside our own borders is high, and is generally a function of our trade situation; if we're buying more from other countries than they are from us, then our dollars are flooding the currency exchange markets and thus become cheaper because they're easy to get. Again, there are other variables at play here that keep our currency strong. First off, again, it's bad everywhere; nobody's buying anything from anyone (relatively speaking) and so the relative trade deficits aren't moving much. In addition, devaluation without inflation is self-stablizing; if currency devalues but inflation is low, the cheaper currency makes the things that currency can buy cheaper, which encourages people to buy them. At the same time, the more expensive foreign currency increases the cost in dollars of foreign-made goods. All of this can be beneficial from a money policy standpoint; devaluation makes American goods cheaper to Americans and to foreign consumers alike than foreign goods, and so a policy that puts downward pressure on the dollar but doesn't make inflation a risk can help American manufacturing and other producer businesses. China knows this just as well as we do, and for decades has been artificially fixing the exchange rate of the Renmin B (Yuan) lower than its true value against the dollar, meaning that no matter how cheap American goods get on the world market, Chinese goods are still cheaper, because by definition the Yuan has greater purchasing power for the same cost in dollars. In addition, dollars aren't only used to buy American-made goods and services. The U.S. has positioned its currency over the years to be an international medium of trade for several key commodities (like oil), and the primary currency for global lenders like the IMF and the World Bank. That means that dollars become necessary to buy these things, and are received from and must be repaid to these institutions, and thus the dollar has a built-in demand pretty much regardless of our trade deficits. On top of all that, a lot of countries base their own currencies on our dollar, by basically buying dollars (using other valuable media like gold or oil) and then holding that cash in their own central banks as the store of value backing their own paper money. This is called a \"\"dollar board\"\". Their money becomes worth a particular fraction of a dollar by definition, and that relationship is very precisely controllable; with 10 billion dollars in the vault, and 20 billion Kabukis issued from Kabukistan's central bank, a Kabuki is worth $.50. Print an additional 20 billion Kabuki and the value of one Kabuki decreases to $.25; buy an additional 10 billion dollars and the Kabuki's value increases again to $.50. Quite a few countries do this, mostly in South America, again creating a built-in demand for U.S. dollars and also tying the U.S. dollar to the value of the exports of that country. If Kabukistan's goods become highly demanded by Europe, and its currency increases relative to the dollar, then the U.S. dollar gets a boost because by definition it is worth an exact, fixed number of Kabukis (and also because a country with a dollar board typically has no problem accepting dollars as payment and then printing Kabukis to maintain the exchange rate)\"", "title": "" }, { "docid": "263648", "text": "On my recent visit to the bank, I was told that money coming into the NRE account can only be foreign currency and for NRO accounts, the money can come in local currency but has to be a valid source of income (e.g. rent or investments in India).

The main reason is because your expenses are in the local currency. If you are planning on spending most of your money on foreign travel, that's one thing. But for most of us, the bulk of our expenses are incurred locally. So it makes sense for us to invest in things where the investment return is local. You might argue that you can always exchange foreign results into local currency, and that's true. But then you have two risks. One risk you'll have anywhere: your investments may go down. The other risk with a foreign investment is that the currency may lose value relative to your currency. If that happens, even a good performing investment can go down in terms of what it can return to you. That fund denominated in your currency is really doing these conversions behind the scenes. Unless the bulk of your purchases are from imports and have prices that fluctuate with your currency, you will probably be better off in local investments. As a rough rule of thumb, your country's import percentage is a good estimate of how much you should invest globally. That looks to be about 20% for Australia. So consider something like 50% local stocks, 20% local bonds, 15% foreign stocks, 5% foreign bonds, and 10% local cash. That will insulate you a bit from a weak local currency while not leaving you out to dry with a strong local currency. It's possible that your particular expenses might be more (or less) vulnerable to foreign price fluctuations than the typical.

What they were effectively doing is taking the interest you would have earned and used it to place a bet on the stock or index in question. Technically, one way this can be done, for instance, is with call options and zero coupon bonds or notes. But there was nothing to strategize with once the account was set up, so the investor did not need to know how it worked behind the scenes... Looking at the deposit plus offering in particular, this one looks a little more dangerous than what I describe. See, now we are in an economy of low almost zero interest rates. So to boost the offered rate the bank is offering you an account where you guarantee the AUD/HKD rate for the bank in exchange for some extra interest. Effectively they sell AUD options (or want to cover their own AUD exposures) and you get some of that as extra interest. Problem is, if the AUD declines, then you lose money because the savings and interest will be converted to AUD at a contractual rate that you are agreeing to now when you take the deposit plus account.

In its simplest form, the process works like this: I'll illustrate this with an example. I've separated the conversion rate into the exchange rate and a generic \"\"ADR conversion rate\"\" which includes all other factors the bank takes into account when deciding how many ADR shares to sell. The fact that the units line up is a nice check to make sure the calculation is logically correct. My example starts with these assumptions: I made up the generic ADR conversion rate; it will remain constant throughout this example. This is the simplified version of the calculation of the ADR share price from the European share price: Let's assume that the euro appreciates against the US dollar, and is now worth 1.4 USD (this is a major appreciation, but it makes a good example): The currency appreciation alone raised the share price of the ADR, even though the price of the share on the European exchange was unchanged. Now let's look at what happens if the euro appreciates further to 1.5 USD/EUR, but the company's share price on the European exchange falls: Even though the euro appreciated, the decline in the share price on the European exchange offset the currency risk in this case, leaving the ADR's share price on the US exchange unchanged. Finally, what happens if the euro experiences a major depreciation and the company's share price decreases significantly in the European market? This is a realistic situation that has occurred several times during the European sovereign debt crisis. Assuming this occurred immediately after the first example, European shareholders in the company experienced a (43.50 - 50) / 50 = -13% return, but American holders of the ADR experienced a (15.95 - 21.5093) / 21.5093 = -25.9% return. The currency shock was the primary cause of this magnified loss. Another point to keep in mind is that the foreign company itself may be exposed to currency risk if it conducts a lot of business in market with different currencies. Ideally the company has hedged against this, but if you invest in a foreign company through an ADR (or a GDR or another similar instrument), you may take on whatever risk the company hasn't hedged in addition to the currency risk that's present in the ADR/GDR conversion process.

Anopheles gambiae s.s. contributed most to the transmission of P. falciparum along the coast as a whole, while An. funestus accounted for more than 50% of all transmission in Kwale District. Large spatial heterogeneity of transmission intensity (< 1 up to 120 infective bites per person per year) resulted in correspondingly large and significantly related variations in parasite prevalence (range = 38-83%). Thirty-two percent of the sites (7 of 22 sites) with malaria prevalences ranging from 38% to 70% had annual entomologic inoculation rates (EIR) less than five infective bites per person per year.

However, both were positively correlated with rainfall one and three months previously in Malindi and Kilifi Districts, respectively. These unexpected variations in the relationship between mosquito populations and rainfall suggest environmental heterogeneity in the predominant aquatic habitats in each district. One important conclusion is that the highly non-linear relationship between EIRs and prevalence indicates that the consistent pattern of high prevalence might be governed by substantial variation in transmission intensity measured by entomologic surveys.

Over a wide range of transmission intensities there is little relationship between the infectiousness of human populations to vector mosquitoes and mosquito-to-human transmission intensity.

We incorporated the effect of the switch to artemisinin-combination therapy (ACT) and increasing coverage of long-lasting insecticide treated nets (LLINs) from the year 2000 onwards. We then explored the impact on transmission of continued roll-out of LLINs, additional rounds of indoor residual spraying (IRS), mass screening and treatment (MSAT), and a future RTS,S/AS01 vaccine in six representative settings with varying transmission intensity (as summarized by the annual entomological inoculation rate, EIR: 1 setting with low, 3 with moderate, and 2 with high EIRs), vector-species combinations, and patterns of seasonality. In all settings we considered a realistic target of 80% coverage of interventions. In the low-transmission setting (EIR approximately 3 ibppy [infectious bites per person per year]), LLINs have the potential to reduce malaria transmission to low levels (<1% parasite prevalence in all age-groups) provided usage levels are high and sustained. In two of the moderate-transmission settings (EIR approximately 43 and 81 ibppy), additional rounds of IRS with DDT coupled with MSAT could drive parasite prevalence below a 1% threshold. However, in the third (EIR = 46) with An. arabiensis prevailing, these interventions are insufficient to reach this threshold. In both high-transmission settings (EIR approximately 586 and 675 ibppy), either unrealistically high coverage levels (>90%) or novel tools and/or substantial social improvements will be required, although considerable reductions in prevalence can be achieved with existing tools and realistic coverage levels. CONCLUSIONS Interventions using current tools can result in major reductions in P. falciparum malaria transmission and the associated disease burden in Africa.

Multivariable regression was used to investigate the role of ACT versus non-artemisinin antimalarial treatment, treatment failure, presence of pre-treatment gametocytes and submicroscopic gametocytaemia on transmission to mosquitoes and the area under the curve (AUC) of gametocyte density during the 28 days of follow up. RESULTS ACT treatment was associated with a significant reduction in the probability of being gametocytaemic on the day of transmission experiments (OR 0.20 95% CI 0.16-0.26), transmission to mosquitoes by slide-positive gametocyte carriers (OR mosquito infection 0.49 95% CI 0.33-0.73) and AUC of gametocyte density (ratio of means 0.35 95% CI 0.31-0.41).

Statistical analysis was done using SAS 9.1. RESULTS Six hundred and ninety five children with acute uncomplicated malaria participated in the study. The mean age was 51.7 months +/- 33.8. At presentation, anaemia occurred in 43.8% of the patients and children <5 yr had a significantly lower haematocrit (28.4% +/- 4.8) than that of older children (32.8% +/- 4.8) (p <0.001), but the haematocrit was not significantly different by days 14 and 28. There was no difference between both sexes. Leucocytosis was more frequently seen than leucopenia (9.5% vs 3%). Thrombocytopenia was found in 59.3% of enrolled patients. More than half of the patients with thrombocytopenia had recovered by Day 28. Baseline platelet count was related to Day 14 (r = 0.6, p < 0.0001) and Day 28 (r = 0.2, p = 0.0015) and the haematocrit on Day 28 (r = 0.12, p = 0.00197). Platelet count showed no correlation with temperature, parasite density and leucocyte count. Haematocrit correlated with age (r = 0.4, p < 0.0001); but not with parasite density or temperature. Leucocyte count showed no correlation with age or parasite density.

Children with malaria had a higher WCC compared with community controls, and leucocytosis was strongly associated with younger age, deep breathing, severe anaemia, thrombocytopenia and death. The WCC was not associated with a positive blood culture. In children with malaria, high lymphocyte and low monocyte counts were independently associated with mortality.

A recent field study in an area of low seasonal transmission in South West Cambodia demonstrated dramatic reductions in malaria parasite prevalence following both mass drug administration (MDA) and high treatment coverage of symptomatic patients with artemisinin-piperaquine plus primaquine. This study employed multiple combined strategies and it was unclear what contribution each made to the reductions in malaria. METHOD AND FINDINGS A mathematical model fitted to the trial results was used to assess the effects of the various components of these interventions, design optimal elimination strategies, and explore their interactions with artemisinin resistance, which has recently been discovered in Western Cambodia. The modelling indicated that most of the initial reduction of P. falciparum malaria resulted from MDA with artemisinin-piperaquine. The subsequent continued decline and near elimination resulted mainly from high coverage with artemisinin-piperaquine treatment. Both these strategies were more effective with the addition of primaquine. MDA with artemisinin combination therapy (ACT) increased the proportion of artemisinin resistant infections, although much less than treatment of symptomatic cases with ACT, and this increase was slowed by adding primaquine. Artemisinin resistance reduced the effectiveness of interventions using ACT when the prevalence of resistance was very high. The main results were robust to assumptions about primaquine action, and immunity. CONCLUSIONS The key messages of these modelling results for policy makers were: high coverage with ACT treatment can produce a long-term reduction in malaria whereas the impact of MDA is generally only short-term; primaquine enhances the effect of ACT in eliminating malaria and reduces the increase in proportion of artemisinin resistant infections; parasite prevalence is a better surveillance measure for elimination programmes than numbers of symptomatic cases; combinations of interventions are most effective and sustained efforts are crucial for successful elimination.", "title": "Optimising Strategies for Plasmodium falciparum Malaria Elimination in Cambodia: Primaquine, Mass Drug Administration and Artemisinin Resistance" }, { "docid": "2264455", "text": "There is no licenced vaccine against any human parasitic disease and Plasmodium falciparum malaria, a major cause of infectious mortality, presents a great challenge to vaccine developers.

Malaria vaccine development has been at the forefront of assessing many new vaccine technologies including novel adjuvants, vectored prime-boost regimes and the concept of community vaccination to block malaria transmission. Most current vaccine candidates target a single stage of the parasite's life cycle and vaccines against the early pre-erythrocytic stages have shown most success.

Individuals homozygous for alpha(+)-thalassaemia have microcytosis and an increased erythrocyte count. Alpha(+)-thalassaemia homozygosity confers considerable protection against severe malaria, including severe malarial anaemia (SMA) (Hb concentration < 50 g/l), but does not influence parasite count. We tested the hypothesis that the erythrocyte indices associated with alpha(+)-thalassaemia homozygosity provide a haematological benefit during acute malaria. METHODS AND FINDINGS Data from children living on the north coast of Papua New Guinea who had participated in a case-control study of the protection afforded by alpha(+)-thalassaemia against severe malaria were reanalysed to assess the genotype-specific reduction in erythrocyte count and Hb levels associated with acute malarial disease. We observed a reduction in median erythrocyte count of approximately 1.5 x 10(12)/l in all children with acute falciparum malaria relative to values in community children (p < 0.001). We developed a simple mathematical model of the linear relationship between Hb concentration and erythrocyte count. This model predicted that children homozygous for alpha(+)-thalassaemia lose less Hb than children of normal genotype for a reduction in erythrocyte count of >1.1 x 10(12)/l as a result of the reduced mean cell Hb in homozygous alpha(+)-thalassaemia. In addition, children homozygous for alpha(+)-thalassaemia require a 10% greater reduction in erythrocyte count than children of normal genotype (p = 0.02) for Hb concentration to fall to 50 g/l, the cutoff for SMA. We estimated that the haematological profile in children homozygous for alpha(+)-thalassaemia reduces the risk of SMA during acute malaria compared to children of normal genotype (relative risk 0.52; 95% confidence interval [CI] 0.24-1.12, p = 0.09). CONCLUSIONS The increased erythrocyte count and microcytosis in children homozygous for alpha(+)-thalassaemia may contribute substantially to their protection against SMA. A lower concentration of Hb per erythrocyte and a larger population of erythrocytes may be a biologically advantageous strategy against the significant reduction in erythrocyte count that occurs during acute infection with the malaria parasite Plasmodium falciparum. This haematological profile may reduce the risk of anaemia by other Plasmodium species, as well as other causes of anaemia.

With the increased interest in malaria elimination, understanding the impact on transmission of ACT and other antimalarial drugs with different pharmacodynamics becomes a key issue. This study estimates the reduction in transmission that may be achieved by introducing different types of treatment for symptomatic P. falciparum malaria in endemic areas. METHODS AND FINDINGS We developed a mathematical model to predict the potential impact on transmission outcomes of introducing ACT as first-line treatment for uncomplicated malaria in six areas of varying transmission intensity in Tanzania. We also estimated the impact that could be achieved by antimalarials with different efficacy, prophylactic time, and gametocytocidal effects. Rates of treatment, asymptomatic infection, and symptomatic infection in the six study areas were estimated using the model together with data from a cross-sectional survey of 5,667 individuals conducted prior to policy change from sulfadoxine-pyrimethamine to ACT. The effects of ACT and other drug types on gametocytaemia and infectiousness to mosquitoes were independently estimated from clinical trial data. Predicted percentage reductions in prevalence of infection and incidence of clinical episodes achieved by ACT were highest in the areas with low initial transmission. A 53% reduction in prevalence of infection was seen if 100% of current treatment was switched to ACT in the area where baseline slide-prevalence of parasitaemia was lowest (3.7%), compared to an 11% reduction in the highest-transmission setting (baseline slide prevalence = 57.1%). Estimated percentage reductions in incidence of clinical episodes were similar. The absolute size of the public health impact, however, was greater in the highest-transmission area, with 54 clinical episodes per 100 persons per year averted compared to five per 100 persons per year in the lowest-transmission area. High coverage was important. Reducing presumptive treatment through improved diagnosis substantially reduced the number of treatment courses required per clinical episode averted in the lower-transmission settings although there was some loss of overall impact on transmission. An efficacious antimalarial regimen with no specific gametocytocidal properties but a long prophylactic time was estimated to be more effective at reducing transmission than a short-acting ACT in the highest-transmission setting. CONCLUSIONS Our results suggest that ACTs have the potential for transmission reductions approaching those achieved by insecticide-treated nets in lower-transmission settings.

Our results reveal the striking yet intuitive conclusion that gene expression should evolve along very different trajectories in the two interacting species. Specifically, host resistance loci should frequently evolve to co-express alleles, whereas parasite infection loci should evolve to express only a single allele. This result arises because hosts that co-express resistance alleles are able to recognize and clear a greater diversity of parasite genotypes.

Moreover, using an experimental model of LC migration induced by tumor necrosis factor (TNF)-α, we show that parasites transiently impair the departure of LCs from the epidermis and their subsequent accumulation as dendritic cells in the draining lymph nodes. The inhibitory effect is mediated by soluble lipophilic factors released by the parasites and not by host-derived antiinflammatory cytokines, such as interleukin-10. We find that prostaglandin (PG)D2, but not the other major eicosanoids produced by the parasites, specifically impedes the TNF-α–triggered migration of LCs through the adenylate cyclase–coupled PGD2 receptor (DP receptor). Moreover, the potent DP receptor antagonist BW A868C restores LC migration in infected mice. Finally, in a model of contact allergen-induced LC migration, we show that activation of the DP receptor not only inhibits LC emigration but also dramatically reduces the contact hypersensitivity responses after challenge.

PARTICIPANTS 60,746 patients diagnosed as having a new episode of depression between the ages of 65 and 100 years from 1 January 1996 to 31 December 2007 and followed up until 31 December 2008. MAIN OUTCOME MEASURES Hazard ratios associated with antidepressant use for all cause mortality, attempted suicide/self harm, myocardial infarction, stroke/transient ischaemic attack, falls, fractures, upper gastrointestinal bleeding, epilepsy/seizures, road traffic accidents, adverse drug reactions, and hyponatraemia, adjusted for a range of potential confounding variables. Hazard ratios were calculated for antidepressant class (tricyclic and related antidepressants, selective serotonin reuptake inhibitors, other antidepressants), dose, and duration of use and for commonly prescribed individual drugs. RESULTS 54,038 (89.0%) patients received at least one prescription for an antidepressant during follow-up. A total of 1,398,359 antidepressant prescriptions were issued: 764,659 (54.7%) for selective serotonin reuptake inhibitors, 442,192 (31.6%) for tricyclic antidepressants, 2203 (0.2%) for monoamine oxidase inhibitors, and 189,305 (13.5%) for the group of other antidepressants. The associations with the adverse outcomes differed significantly between the antidepressant classes for seven outcomes. Selective serotonin reuptake inhibitors were associated with the highest adjusted hazard ratios for falls (1.66, 95% confidence interval 1.58 to 1.73) and hyponatraemia (1.52, 1.33 to 1.75) compared with when antidepressants were not being used. The group of other antidepressants was associated with the highest adjusted hazard ratios for all cause mortality (1.66, 1.56 to 1.77), attempted suicide/self harm (5.16, 3.90 to 6.83), stroke/transient ischaemic attack (1.37, 1.22 to 1.55), fracture (1.64, 1.46 to 1.84), and epilepsy/seizures (2.24, 1.60 to 3.15), compared with when antidepressants were not being used. Tricyclic antidepressants did not have the highest hazard ratio for any of the outcomes. Significantly different associations also existed between the individual drugs for the same seven outcomes; trazodone (tricyclic antidepressant), mirtazapine, and venlafaxine (both in the group of other antidepressants) were associated with the highest rates for some of these outcomes. Absolute risks over 1 year for all cause mortality were 7.04% for patients while not taking antidepressants, 8.12% for those taking tricyclic antidepressants, 10.61% for selective serotonin reuptake inhibitors, and 11.43% for other antidepressants. CONCLUSIONS Selective serotonin reuptake inhibitors and drugs in the group of other antidepressants were associated with an increased risk of several adverse outcomes compared with tricyclic antidepressants. Among individual drugs, trazodone, mirtazapine, and venlafaxine were associated with the highest risks for some outcomes. As this is an observational study, it is susceptible to confounding by indication, channelling bias, and residual confounding, so differences in characteristics between patients prescribed different antidepressant drugs that could account for some of the associations between the drugs and the adverse outcomes may remain. Further research is needed to confirm these findings, but the risks and benefits of different antidepressants should be carefully evaluated when these drugs are prescribed to older people.", "title": "Antidepressant use and risk of adverse outcomes in older people: population based cohort study" } ]

A previous overview showed that the effects were greatest in regions with low dietary folate consumption, but differentiation between the effect of folate and small-study bias was difficult. A meta-analysis of randomised trials of homocysteine-lowering interventions showed no reduction in coronary heart disease events or stroke, but the trials were generally set in populations with high folate consumption. We aimed to reduce the effect of small-study bias and investigate whether folate status modifies the association between MTHFR 677C→T and stroke in a genetic analysis and meta-analysis of randomised controlled trials. METHODS We established a collaboration of genetic studies consisting of 237 datasets including 59,995 individuals with data for homocysteine and 20,885 stroke events. We compared the genetic findings with a meta-analysis of 13 randomised trials of homocysteine-lowering treatments and stroke risk (45,549 individuals, 2314 stroke events, 269 transient ischaemic attacks). FINDINGS The effect of the MTHFR 677C→T variant on homocysteine concentration was larger in low folate regions (Asia; difference between individuals with TT versus CC genotype, 3·12 μmol/L, 95% CI 2·23 to 4·01) than in areas with folate fortification (America, Australia, and New Zealand, high; 0·13 μmol/L, -0·85 to 1·11). The odds ratio (OR) for stroke was also higher in Asia (1·68, 95% CI 1·44 to 1·97) than in America, Australia, and New Zealand, high (1·03, 0·84 to 1·25). Most randomised trials took place in regions with high or increasing population folate concentrations. The summary relative risk (RR) of stroke in trials of homocysteine-lowering interventions (0·94, 95% CI 0·85 to 1·04) was similar to that predicted for the same extent of homocysteine reduction in large genetic studies in populations with similar folate status (predicted RR 1·00, 95% CI 0·90 to 1·11). Although the predicted effect of homocysteine reduction from large genetic studies in low folate regions (Asia) was larger (RR 0·78, 95% CI 0·68 to 0·90), no trial has evaluated the effect of lowering of homocysteine on stroke risk exclusively in a low folate region. INTERPRETATION In regions with increasing levels or established policies of population folate supplementation, evidence from genetic studies and randomised trials is concordant in suggesting an absence of benefit from lowering of homocysteine for prevention of stroke. Further large-scale genetic studies of the association between MTHFR 677C→T and stroke in low folate settings are needed to distinguish effect modification by folate from small-study bias. If future randomised trials of homocysteine-lowering interventions for stroke prevention are undertaken, they should take place in regions with low folate consumption.

Low folate intake or low plasma folate concentration is associated with increased stroke risk. Previous randomized controlled trials presented discordant findings in the effect of folic acid supplementation-based homocysteine lowering on stroke risk. The aim of the present review was to perform a meta-analysis of relevant randomized controlled trials to check the how different folate fortification status might affect the effects of folic acid supplementation in lowering homocysteine and reducing stroke risk. DESIGN Relevant randomized controlled trials were identified through formal literature search. Homocysteine reduction was compared in subgroups stratified by folate fortification status. Relative risks with 95 % confidence intervals were used as a measure to assess the association between folic acid supplementation and stroke risk. SETTING The meta-analysis included fourteen randomized controlled trials, SUBJECTS A total of 39 420 patients. RESULTS Homocysteine reductions were 26·99 (sd 1·91) %, 18·38 (sd 3·82) % and 21·30 (sd 1·98) %, respectively, in the subgroups without folate fortification, with folate fortification and with partial folate fortification. Significant difference was observed between the subgroups with folate fortification and without folate fortification (P=0·05). The relative risk of stroke was 0·88 (95 % CI 0·77, 1·00, P=0·05) in the subgroup without folate fortification, 0·94 (95 % CI 0·58, 1·54, P=0·82) in the subgroup with folate fortification and 0·91 (95 % CI 0·82, 1·01, P=0·09) in the subgroup with partial folate fortification.

OBJECTIVES To quantify the incidence of ischemic stroke with sleep apnea in a community-based sample of men and women across a wide range of sleep apnea. METHODS Baseline polysomnography was performed between 1995 and 1998 in a longitudinal cohort study. The primary exposure was the obstructive apnea-hypopnea index (OAHI) and outcome was incident ischemic stroke. MEASUREMENTS AND MAIN RESULTS A total of 5,422 participants without a history of stroke at the baseline examination and untreated for sleep apnea were followed for a median of 8.7 years. One hundred ninety-three ischemic strokes were observed. In covariate-adjusted Cox proportional hazard models, a significant positive association between ischemic stroke and OAHI was observed in men (P value for linear trend: P = 0.016). Men in the highest OAHI quartile (>19) had an adjusted hazard ratio of 2.86 (95% confidence interval, 1.1-7.4). In the mild to moderate range (OAHI, 5-25), each one-unit increase in OAHI in men was estimated to increase stroke risk by 6% (95% confidence interval, 2-10%). In women, stroke was not significantly associated with OAHI quartiles, but increased risk was observed at an OAHI greater than 25.

We investigated the association between mild to moderate fasting tHcy level and the incidence of ischemic stroke, myocardial infarction, and vascular death in a multiethnic prospective study. METHODS A population-based cohort was followed for vascular events (stroke, myocardial infarction, and vascular death). Baseline values of tHcy and methylmalonic acid were measured among 2939 subjects (mean age, 69+/-10; 61% women, 53% Hispanics, 24% blacks, and 20% whites). Cox proportional models were used to calculate hazard ratios (HRs) and 95% CIs in tHcy categories after adjusting for age, race, education, renal insufficiency, B12 deficiency, and other risk factors. RESULTS The adjusted HR for a tHcy level > or =15 micromol/L compared with <10 micromol/L was greatest for vascular death (HR=6.04; 95% CI, 3.44 to 10.60), followed by combined vascular events (HR=2.27; 95% CI, 1.51 to 3.43), ischemic stroke (HR=2.01; 95% CI, 1.00 to 4.05), and nonvascular death (HR=2.02; 95% CI, 1.31 to 3.14). Mild to moderate elevations of tHcy of 10 to 15 micromol/L were not significantly predictive of ischemic stroke, but increased the risk of vascular death (2.27; 95% CI, 1.44 to 3.60) and combined vascular events (1.42; 95% CI, 1.06 to 1.88). The effect of tHcy was stronger among whites and Hispanics, but not a significant risk factor for blacks. CONCLUSIONS Total Hcy elevations above 15 micromol/L are an independent risk factor for ischemic stroke, whereas mild elevations of tHcy of 10 to 15 micromol/L are less predictive.

INTERVENTION Patients were randomly assigned to take sildenafil (n = 45) or placebo (n = 45) at a flexible dose starting at 50 mg and adjustable to 100 mg before sexual activity for 6 weeks. MAIN OUTCOME MEASURES The primary outcome measure was score on the Clinical Global Impression-Sexual Function (CGI-SF); secondary measures were scores on the International Index of Erectile Function, Arizona Sexual Experience Scale, Massachusetts General Hospital-Sexual Functioning Questionnaire, and Hamilton Rating Scale for Depression (HAM-D). RESULTS Among the 90 randomized patients, 93% (83/89) of patients treated per protocol took at least 1 dose of study drug and 85% (76/89) completed week 6 end-point assessments with last observation carried forward analyses. At a CGI-SF score of 2 or lower, 54.5% (24/44) of sildenafil compared with 4.4% (2/45) of placebo patients were much or very much improved (P<.001).

Logistic regression was used to examine the associations of baseline serum soluble corin with outcomes of stroke, adjusting for age, sex, baseline NIHSS score, hours from onset to hospitalization, smoking, drinking, hypertension, diabetes, coronary heart disease, atrial fibrillation, family history of stroke, and stroke subtype. RESULTS Patients with high corin had a significantly lower crude risk for the composite outcome of major disability or death (OR = 0.64, 95%CI: 0.43-0.96) than patients with low corin (the lowest tertile). After adjustment for age and baseline NIHSS score, patients with high corin still had a significantly lower risk for the composite outcome of major disability or death (OR = 0.60, 95%CI: 0.36-0.99). This association became bottom line significant after additionally adjusting for other conventional factors (OR = 0.61, P = 0.058). No association was found between serum soluble corin and other composite outcomes. CONCLUSION Serum soluble corin deficiency predicted risk for major disability within 3 months after stroke, independent of baseline neurological deficient.

Six placebo-controlled trials have shown nortriptyline (75-100 mg) doubles quit rates (OR = 2.1). Between 4% and 12% of smokers dropped out because of adverse events, but no serious adverse events occurred. The efficacy of nortriptyline did not appear to be related to its antidepressant actions. Nortriptyline is an efficacious aid to smoking cessation with a magnitude of effect similar to that for bupropion and nicotine replacement therapies. Whether nortriptyline produces serious side effects at these doses in healthy, nondepressed smokers remains unclear because it has been tested in only 500 smokers. The finding that nortriptyline and bupropion are effective for smoking cessation but that selective serotonin-reuptake inhibitors are not suggests that dopaminergic or adrenergic, but not serotonergic, activity is important for cessation efficacy.

STUDY SELECTION Long-term prospective studies that recorded Lp(a) concentration and subsequent major vascular morbidity and/or cause-specific mortality published between January 1970 and March 2009 were identified through electronic searches of MEDLINE and other databases, manual searches of reference lists, and discussion with collaborators. DATA EXTRACTION Individual records were provided for each of 126,634 participants in 36 prospective studies. During 1.3 million person-years of follow-up, 22,076 first-ever fatal or nonfatal vascular disease outcomes or nonvascular deaths were recorded, including 9336 CHD outcomes, 1903 ischemic strokes, 338 hemorrhagic strokes, 751 unclassified strokes, 1091 other vascular deaths, 8114 nonvascular deaths, and 242 deaths of unknown cause. Within-study regression analyses were adjusted for within-person variation and combined using meta-analysis. Analyses excluded participants with known preexisting CHD or stroke at baseline. DATA SYNTHESIS Lipoprotein(a) concentration was weakly correlated with several conventional vascular risk factors and it was highly consistent within individuals over several years. Associations of Lp(a) with CHD risk were broadly continuous in shape. In the 24 cohort studies, the rates of CHD in the top and bottom thirds of baseline Lp(a) distributions, respectively, were 5.6 (95% confidence interval [CI], 5.4-5.9) per 1000 person-years and 4.4 (95% CI, 4.2-4.6) per 1000 person-years. The risk ratio for CHD, adjusted for age and sex only, was 1.16 (95% CI, 1.11-1.22) per 3.5-fold higher usual Lp(a) concentration (ie, per 1 SD), and it was 1.13 (95% CI, 1.09-1.18) following further adjustment for lipids and other conventional risk factors. The corresponding adjusted risk ratios were 1.10 (95% CI, 1.02-1.18) for ischemic stroke, 1.01 (95% CI, 0.98-1.05) for the aggregate of nonvascular mortality, 1.00 (95% CI, 0.97-1.04) for cancer deaths, and 1.00 (95% CI, 0.95-1.06) for nonvascular deaths other than cancer.

The mechanism of action of these polymorphisms has yet to be defined. We used mRNA allelic expression and splice isoform measurements in human liver tissues to identify the genetic variants affecting CETP levels. Allelic CETP mRNA expression ratios in 56 human livers were strongly associated with several variants 2.5-7 kb upstream of the transcription start site (e.g., rs247616 p = 6.4 × 10(-5), allele frequency 33%). In addition, a common alternatively spliced CETP isoform lacking exon 9 (Δ9), has been shown to prevent CETP secretion in a dominant-negative manner. The Δ 9 expression ranged from 10 to 48% of total CETP mRNA in 94 livers. Increased formation of this isoform was exclusively associated with an exon 9 polymorphism rs5883-C>T (p = 6.8 × 10(-10)) and intron 8 polymorphism rs9930761-T>C (5.6 × 10(-8)) (in high linkage disequilibrium with allele frequencies 6-7%). rs9930761 changes a key splicing branch point nucleotide in intron 8, while rs5883 alters an exonic splicing enhancer sequence in exon 9.The effect of these polymorphisms was evaluated in two clinical studies. In the Whitehall II study of 4745 subjects, both rs247616 and rs5883T/rs9930761C were independently associated with increased HDL-C levels in males with similar effect size (rs247616 p = 9.6 × 10(-28) and rs5883 p = 8.6 × 10(-10), adjusted for rs247616).

Acupoints used were Neiguan (PC 6), Renzhong (GV 26), Baihui (GV 20), Yintang (EX-HN 3) and Sanyinjiao (SP 6,the affected side) and the needles were retained for 20 min every time. Patients of medication group were asked to take Amitriptyline (50 mg/d at first, 200 mg/d). Acupuncture treatment was conducted twice daily, and after one month's treatment the therapeutic effect was evaluated.

RESULTS After the treatment, of the 180 and 76 cases in acupuncture and medication groups, 31 (17.2%) and 13 (17.1%) were cured, 73 (40.6%) and 18 (23.7%) had a marked improvement in their depression state, 27 (15.0%) and 12 (15.8%) had an improvement, 49 (27.2%) and 33 (43.4%) failed, with the effective rates being 72.8% and 56.6% respectively. The markedly effective rate and the total effective rate of acupuncture group were significantly higher than those of medication group (P < 0.05). After the treatment, the total scores of SDS and HRSD and the severity index of two groups decreased pronouncedly in comparison with those of their individual pre-treatment; and the therapeutic effects of acupuncture group were significantly better than those of medication group in reducing SDS, HRSD and severity index (P < 0 .05).

CC is a safe, effective oral agent but is known to have relatively common antiestrogenic endometrial and cervical mucous side effects that could prevent pregnancy in the face of successful ovulation. In addition, there is a significant risk of multiple pregnancy with CC, compared with natural cycles. Because of these problems, we proposed the concept of aromatase inhibition as a new method of ovulation induction that could avoid many of the adverse effects of CC. The objective of this review was to describe the different physiological mechanisms of action for CC and aromatase inhibitors (AIs) and compare studies of efficacy for both agents for ovulation induction. EVIDENCE ACQUISITION We conducted a systematic review of all the published studies, both controlled and noncontrolled, comparing CC and AI treatment, either alone or in combination with gonadotropins, for ovulation induction or augmentation, identified through the Entrez-PubMed search engine. EVIDENCE SYNTHESIS Because of the recent acceptance of the concept of using AIs for ovulation induction, few controlled studies were identified, and the rest of the studies were pilot or preliminary comparisons. Based on these studies, it appears that AIs are as effective as CC in inducing ovulation, are devoid of any antiestrogenic side effects, result in lower serum estrogen concentrations, and are associated with good pregnancy rates with a lower incidence of multiple pregnancy than CC. When combined with gonadotropins for assisted reproductive technologies, AIs reduce the dose of FSH required for optimal follicle recruitment and improve the response to FSH in poor responders. CONCLUSIONS Preliminary evidence suggests that AIs may replace CC in the future because of similar efficacy with a reduced side effect profile.

Only a few studies, however, have addressed this issue directly. PURPOSE We assessed the risk of developing endometrial cancer among both premenopausal and postmenopausal women in relation to the circulating levels of steroid hormones and sex hormone-binding globulin (SHBG). The independent effect of hormones was assessed after adjustment for other known risk factors. METHODS The data used in the analysis are from a case-control study conducted in five geographic regions in the United States. Incident cases were newly diagnosed during the period from June 1, 1987, through May 15, 1990. The case patients, aged 20-74 years, were matched to control subjects by age, race, and geographic region. The community control subjects were obtained by random-digit-dialing procedures (for subjects 20-64 years old) and from files of the Health Care Financing Administration (for subjects > or = 65 years old). Additional control subjects who were having a hysterectomy performed for benign conditions were obtained from the participating centers. Women reporting use of exogenous estrogens or oral contraceptives within 6 months of interview were excluded, resulting in 68 case patients and 107 control subjects among premenopausal women and 208 case patients and 209 control subjects among postmenopausal women. The hormone analyses were performed on blood samples obtained from case patients or from hysterectomy control subjects before surgery. The odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by use of an unconditional logistic regression analysis after we controlled for matching variables and potential confounders. All P values were two-sided. RESULTS High circulating levels of androstenedione were associated with 3.6-fold and 2.8-fold increased risks among premenopausal and postmenopausal women, respectively, after adjustment for other factors (P for trend = .01 and < .001, respectively). Risks related to other hormone fractions varied by menopausal status. Among postmenopausal women, a reduced risk was associated with high SHBG levels and persisted after adjustment was made for obesity and other factors (OR = 0.51; 95% CI = 0.27-0.95). High estrone levels were associated with increased risk (OR = 3.8; 95% CI = 2.2-6.6), although adjustment for other risk factors (particularly body mass index) diminished the effect (OR = 2.2; 95% CI = 1.2-4.4). Albumin-bound estradiol (E2), a marker of the bioavailable fraction, also remained an important risk factor after adjustment was made for other factors (OR = 2.0; 95% CI = 1.0-3.9). In contrast, high concentrations of total, free, and albumin-bound E2 were unrelated to increased risk in premenopausal women. In both premenopausal and postmenopausal groups, risks associated with obesity and fat distribution were not affected by adjustment for hormones. CONCLUSION High endogenous levels of unopposed estrogen are related to increased risk of endometrial cancer, but their independence from other risk factors is inconsistent with being a common underlying biologic pathway through which all risk factors for endometrial cancer operate.

Participants were adults aged 25 through 64 years with dispensed prescriptions for methylphenidate, amphetamine, or atomoxetine at baseline. Each medication user (n = 150,359) was matched to 2 nonusers on study site, birth year, sex, and calendar year (443,198 total users and nonusers). MAIN OUTCOME MEASURES Serious cardiovascular events, including myocardial infarction (MI), sudden cardiac death (SCD), or stroke, with comparison between current or new users and remote users to account for potential healthy-user bias. RESULTS During 806,182 person-years of follow-up (median, 1.3 years per person), 1357 cases of MI, 296 cases of SCD, and 575 cases of stroke occurred. There were 107,322 person-years of current use (median, 0.33 years), with a crude incidence per 1000 person-years of 1.34 (95% CI, 1.14-1.57) for MI, 0.30 (95% CI, 0.20-0.42) for SCD, and 0.56 (95% CI, 0.43-0.72) for stroke. The multivariable-adjusted rate ratio (RR) of serious cardiovascular events for current use vs nonuse of ADHD medications was 0.83 (95% CI, 0.72-0.96). Among new users of ADHD medications, the adjusted RR was 0.77 (95% CI, 0.63-0.94).

HDL-C represents an important aspect of the syndrome, yet its role in breast cancer is still undefined. METHODS In two population-based screening surveys during 1977-1983 and 1985-1987, serum HDL-C was assayed enzymatically among 38,823 Norwegian women aged 17-54 years at entry. Height, weight, blood pressure, serum lipids, fat and energy intake, physical activity, parity, oral contraceptive use, hormone therapy use, alcohol intake, and tobacco use were also assessed. We used Cox proportional hazards modeling to estimate the relative risk (RR) of breast cancer associated with serum HDL-C levels and to adjust for potential confounding variables. We performed stratified analyses to evaluate effect modification by body mass index (BMI) and menopausal status. All statistical tests were two-sided. RESULTS During a median follow-up of 17.2 years, we identified 708 cases of invasive breast cancer. In multivariable analysis, the risk of postmenopausal breast cancer was inversely related to quartile of HDL-C (P(trend) =.02). Among women with HDL-C above 1.64 mmol/L (highest quartile) versus below 1.20 mmol/L (lowest quartile), the relative risk was 0.75 (95% confidence interval [CI] = 0.58 to 0.97). The HDL-C association was confined to women in the heavier subgroup (BMI > or =25 kg/m2), for whom the relative risk of postmenopausal breast cancer in those with HDL-C above 1.64 mmol/L versus below 1.20 mmol/L was 0.43 (95% CI = 0.28 to 0.67; P(trend)<.001; P(interaction) =.001).

In small trials of patients undergoing surgery, graduated compression stockings (GCS) reduce the risk of DVT. National stroke guidelines extrapolating from these trials recommend their use in patients with stroke despite insufficient evidence. We assessed the effectiveness of thigh-length GCS to reduce DVT after stroke. METHODS In this outcome-blinded, randomised controlled trial, 2518 patients who were admitted to hospital within 1 week of an acute stroke and who were immobile were enrolled from 64 centres in the UK, Italy, and Australia. Patients were allocated via a central randomisation system to routine care plus thigh-length GCS (n=1256) or to routine care plus avoidance of GCS (n=1262). A technician who was blinded to treatment allocation undertook compression Doppler ultrasound of both legs at about 7-10 days and, when practical, again at 25-30 days after enrolment. The primary outcome was the occurrence of symptomatic or asymptomatic DVT in the popliteal or femoral veins. Analyses were by intention to treat. This study is registered, number ISRCTN28163533.

The primary outcome occurred in 126 (10.0%) patients allocated to thigh-length GCS and in 133 (10.5%) allocated to avoid GCS, resulting in a non-significant absolute reduction in risk of 0.5% (95% CI -1.9% to 2.9%).

Experts from 15 countries reviewed all studies. Included articles were those that reported on completed and attempted suicide and suicidal ideation; or, where applicable, intermediate outcomes, including help-seeking behavior, identification of at-risk individuals, entry into treatment, and antidepressant prescription rates.

METHODS In the worldwide Adjuvant Tamoxifen: Longer Against Shorter (ATLAS) trial, 12,894 women with early breast cancer who had completed 5 years of treatment with tamoxifen were randomly allocated to continue tamoxifen to 10 years or stop at 5 years (open control). Allocation (1:1) was by central computer, using minimisation. After entry (between 1996 and 2005), yearly follow-up forms recorded any recurrence, second cancer, hospital admission, or death. We report effects on breast cancer outcomes among the 6846 women with ER-positive disease, and side-effects among all women (with positive, negative, or unknown ER status). Long-term follow-up still continues. This study is registered, number ISRCTN19652633. FINDINGS Among women with ER-positive disease, allocation to continue tamoxifen reduced the risk of breast cancer recurrence (617 recurrences in 3428 women allocated to continue vs 711 in 3418 controls, p=0·002), reduced breast cancer mortality (331 deaths vs 397 deaths, p=0·01), and reduced overall mortality (639 deaths vs 722 deaths, p=0·01). The reductions in adverse breast cancer outcomes appeared to be less extreme before than after year 10 (recurrence rate ratio [RR] 0·90 [95% CI 0·79–1·02] during years 5–9 and 0·75 [0·62–0·90] in later years; breast cancer mortality RR 0·97 [0·79–1·18] during years 5–9 and 0·71 [0·58–0·88] in later years). The cumulative risk of recurrence during years 5–14 was 21·4% for women allocated to continue versus 25·1% for controls; breast cancer mortality during years 5–14 was 12·2% for women allocated to continue versus 15·0% for controls (absolute mortality reduction 2·8%). Treatment allocation seemed to have no effect on breast cancer outcome among 1248 women with ER-negative disease, and an intermediate effect among 4800 women with unknown ER status. Among all 12,894 women, mortality without recurrence from causes other than breast cancer was little affected (691 deaths without recurrence in 6454 women allocated to continue versus 679 deaths in 6440 controls; RR 0·99 [0·89–1·10]; p=0·84). For the incidence (hospitalisation or death) rates of specific diseases, RRs were as follows: pulmonary embolus 1·87 (95% CI 1·13–3·07, p=0·01 [including 0·2% mortality in both treatment groups]), stroke 1·06 (0·83–1·36), ischaemic heart disease 0·76 (0·60–0·95, p=0·02), and endometrial cancer 1·74 (1·30–2·34, p=0·0002). The cumulative risk of endometrial cancer during years 5–14 was 3·1% (mortality 0·4%) for women allocated to continue versus 1·6% (mortality 0·2%) for controls (absolute mortality increase 0·2%).

PARTICIPANTS Two hundred three adults (mean age, 37 years; 76% women) with diagnosis of chronic tension-type headaches (mean, 26 headache d/mo). INTERVENTIONS Participants were randomly assigned to receive tricyclic antidepressant (amitriptyline hydrochloride, up to 100 mg/d, or nortriptyline hydrochloride, up to 75 mg/d) medication (n = 53), placebo (n = 48), stress management (eg, relaxation, cognitive coping) therapy (3 sessions and 2 telephone contacts) plus placebo (n = 49), or stress management therapy plus antidepressant medication (n = 53). MAIN OUTCOME MEASURES Monthly headache index scores calculated as the mean of pain ratings (0-10 scale) recorded by participants in a daily diary 4 times per day; number of days per month with at least moderate pain (pain rating >/=5), analgesic medication use, and Headache Disability Inventory scores, compared by intervention group. RESULTS Tricyclic antidepressant medication and stress management therapy each produced larger reductions in headache activity, analgesic medication use, and headache-related disability than placebo, but antidepressant medication yielded more rapid improvements in headache activity. Combined therapy was more likely to produce clinically significant (>/=50%) reductions in headache index scores (64% of participants) than antidepressant medication (38% of participants; P =.006), stress management therapy (35%; P =.003), or placebo (29%; P =.001). On other measures the combined therapy and its 2 component therapies produced similar outcomes. CONCLUSIONS Our results indicate that antidepressant medication and stress management therapy are each modestly effective in treating chronic tension-type headaches. Combined therapy may improve outcome relative to monotherapy.", "title": "Management of chronic tension-type headache with tricyclic antidepressant medication, stress management therapy, and their combination: a randomized controlled trial." }, { "docid": "6327940", "text": "Amino acids modulate the secretion of both insulin and glucagon; the composition of dietary protein therefore has the potential to influence the balance of glucagon and insulin activity. Soy protein, as well as many other vegan proteins, are higher in non-essential amino acids than most animal-derived food proteins, and as a result should preferentially favor glucagon production. Acting on hepatocytes, glucagon promotes (and insulin inhibits) cAMP-dependent mechanisms that down-regulate lipogenic enzymes and cholesterol synthesis, while up-regulating hepatic LDL receptors and production of the IGF-I antagonist IGFBP-1. The insulin-sensitizing properties of many vegan diets--high in fiber, low in saturated fat--should amplify these effects by down-regulating insulin secretion. Additionally, the relatively low essential amino acid content of some vegan diets may decrease hepatic IGF-I synthesis. Thus, diets featuring vegan proteins can be expected to lower elevated serum lipid levels, promote weight loss, and decrease circulating IGF-I activity. The latter effect should impede cancer induction (as is seen in animal studies with soy protein), lessen neutrophil-mediated inflammatory damage, and slow growth and maturation in children. In fact, vegans tend to have low serum lipids, lean physiques, shorter stature, later puberty, and decreased risk for certain prominent 'Western' cancers; a vegan diet has documented clinical efficacy in rheumatoid arthritis. Low-fat vegan diets may be especially protective in regard to cancers linked to insulin resistance--namely, breast and colon cancer--as well as prostate cancer; conversely, the high IGF-I activity associated with heavy ingestion of animal products may be largely responsible for the epidemic of 'Western' cancers in wealthy societies. Increased phytochemical intake is also likely to contribute to the reduction of cancer risk in vegans. Regression of coronary stenoses has been documented during low-fat vegan diets coupled with exercise training; such regimens also tend to markedly improve diabetic control and lower elevated blood pressure. Risk of many other degenerative disorders may be decreased in vegans, although reduced growth factor activity may be responsible for an increased risk of hemorrhagic stroke. By altering the glucagon/insulin balance, it is conceivable that supplemental intakes of key non-essential amino acids could enable omnivores to enjoy some of the health advantages of a vegan diet. An unnecessarily high intake of essential amino acids--either in the absolute sense or relative to total dietary protein--may prove to be as grave a risk factor for 'Western' degenerative diseases as is excessive fat intake.", "title": "Vegan proteins may reduce risk of cancer, obesity, and cardiovascular disease by promoting increased glucagon activity." }, { "docid": "13883546", "text": "The term antidepressant refers to a drug that helps to rectify specific biological abnormalities that give rise to the symptoms of depression. This exemplifies what we have called the “disease-centred” model of psychotropic drug action [ 1]. Modelled on paradigmatic situations in general medicine—such as the use of insulin in diabetes, antibiotics in infectious disease, chemotherapy in cancer—the disease-centred model suggests that antidepressants help restore normal functioning by acting on the neuropathology of depression or of depressive symptoms. In contrast, we propose in this Essay that an alternative “drug-centred” model can better explain observed drug effects in psychiatric conditions. This drug-centred model suggests that instead of relieving a hypothetical biochemical abnormality, drugs themselves cause abnormal states, which may coincidentally relieve psychiatric symptoms ( Table 1). Alcohol's disinhibiting effects may relieve symptoms of social phobia, but that does not imply that alcohol corrects a chemical imbalance underlying social phobia. Sedation may lessen high arousal, present in many acute psychiatric situations. Drugs that induce indifference, such as neuroleptics or opiates, may help reduce the distress of acute psychotic symptoms. Low-dose stimulants may help improve attention and concentration in the short term. Table 1 Main Assumptions of Two Models of Psychotropic Drug Action The disease-centred model in psychiatry leads researchers to infer antidepressant effects from patients' scores on symptom rating scales presumed to assess the manifestations of the disease. The drug-centred model, on the other hand, suggests that physiological and subjective effects of drugs should be examined in their own right. These effects include various forms of sedation, stimulation, and a plethora of biopsychological states. Depending on individual inclination and context (including a person's emotional state upon drug ingestion), intoxication with some drugs produces euphoria or mood elevation. Because tolerance develops, however, euphoriant effects do not persist with long-term use. If antidepressants or any other psychotropic drugs could be shown to have mood-elevating effects that were long-term and not diminished by being in a depressed emotional state, this would distinguish them from psychotropic drugs that cause euphoria and might prove uniquely useful in depressed patients (see Sidebar).", "title": "Do Antidepressants Cure or Create Abnormal Brain States?" } ]

Most intoxicated cases are from ingestion, inhalation, and skin exposure. Intramuscular injection of GlySH has never been reported. We present a case of GlySH intoxication via intramuscular injection. CASE REPORT: A 42-year-old woman came to the emergency department complaining of painful swelling of left upper limb for 12 h. She had performed an intramuscular injection of 6 mL of GlySH over the lateral aspect of the left elbow 15 h previously. Physical examination disclosed painful swelling over left distal arm, elbow, and forearm with three needle punctures. CT scan revealed ill-defined areas of heterogeneous high density with marked swelling at subcutaneous tissue over posterior aspect of the elbow. DISCUSSION: The mechanism of toxicity of GlySH is complicated and surfactant was thought to play an important role in GlySH intoxication. Intramuscular GlySH poisoning is different from oral GlySH intoxication. Care should be taken when monitoring acute rhabdomyolysis and compartment syndrome, which may develop rapidly and contribute to the surfactant component of glyphosate formulation.", "title": "Rhabdomyolysis from an intramuscular injection of glyphosate-surfactant herbicide." }, { "docid": "MED-3935", "text": "Background Parkinson’s disease (PD) is the second most common neurodegenerative disorder.

Results We describe the conclusions around which they came to consensus with respect to environmental contributors to PD risk. We conclude with a brief summary of research needs. Conclusions PD is a complex disorder, and multiple different pathogenic pathways and mechanisms can ultimately lead to PD. Within the individual there are many determinants of PD risk, and within populations, the causes of PD are heterogeneous. Although rare recognized genetic mutations are sufficient to cause PD, these account for < 10% of PD in the U.S. population, and incomplete penetrance suggests that environmental factors may be involved. Indeed, interplay among environmental factors and genetic makeup likely influences the risk of developing PD. There is a need for further understanding of how risk factors interact, and studying PD is likely to increase understanding of other neurodegenerative disorders.", "title": "Meeting Report: Consensus Statement—Parkinson’s Disease and the Environment: Collaborative on Health and the Environment and Parkinson’s Action Network (CHE PAN) Conference 26–28 June 2007" }, { "docid": "MED-1744", "text": "Eighty percent of (commercial) genetically engineered seeds (GES) are designed only to resist herbicides.

The present, smaller cross-sectional study of 695 families and 1,532 children, conducted during 1997-1998, provides a more detailed examination of reproductive health outcomes in farm families ascertained from parent-reported birth defects. In the present study, in the first year of life, the birth defect rate was 31.3 births per 1,000, with 83% of the total reported birth defects confirmed by medical records. Inclusion of children identified with birth or developmental disorders within the first 3 years of life and later led to a rate of 47.0 per 1,000 (72 children from 1,532 live births). Conceptions in spring resulted in significantly more children with birth defects than found in any other season (7.6 vs. 3.7%). Twelve families had more than one child with a birth defect (n = 28 children). Forty-two percent of the children from families with recurrent birth defects were conceived in spring, a significantly higher rate than that for any other season. Three families in the kinships defined contributed a first-degree relative other than a sibling with the same or similar birth defect, consistent with a Mendelian inheritance pattern. The remaining nine families did not follow a Mendelian inheritance pattern. The sex ratio of children with birth defects born to applicator families shows a male predominance (1.75 to 1) across specific pesticide class use and exposure categories exclusive of fungicides. In the fungicide exposure category, normal female births significantly exceed male births (1.25 to 1). Similarly, the proportion of male to female children with birth defects is significantly lower (0.57 to 1; p = 0.02). Adverse neurologic and neurobehavioral developmental effects clustered among the children born to applicators of the fumigant phosphine (odds ratio [OR] = 2.48; confidence interval [CI], 1.2-5.1). Use of the herbicide glyphosate yielded an OR of 3.6 (CI, 1.3-9.6) in the neurobehavioral category. Finally, these studies point out that (a) herbicides applied in the spring may be a factor in the birth defects observed and (b) fungicides can be a significant factor in the determination of sex of the children of the families of the RRV.

As a model system we have used sea urchin embryonic first divisions following fertilization, which are appropriate for the study of universal cell cycle regulation without interference with transcription. We show that 0.8% Roundup (containing 8 mM glyphosate) induces a delay in the kinetic of the first cell cleavage of sea urchin embryos. The delay is dependent on the concentration of Roundup. The delay in the cell cycle could be induced using increasing glyphosate concentrations (1-10 mM) in the presence of a subthreshold concentration of Roundup 0.2%, while glyphosate alone was ineffective, thus indicating synergy between glyphosate and Roundup formulation products. The effect of Roundup was not lethal and involved a delay in entry into M-phase of the cell cycle, as judged cytologically. Since CDK1/cyclin B regulates universally the M-phase of the cell cycle, we analyzed CDK1/cyclin B activation during the first division of early development. Roundup delayed the activation of CDK1/cyclin B in vivo. Roundup inhibited also the global protein synthetic rate without preventing the accumulation of cyclin B. In summary, Roundup affects cell cycle regulation by delaying activation of the CDK1/cyclin B complex, by synergic effect of glyphosate and formulation products.

Clinical data were correlated to information regarding the trauma mechanism, the sociocultural background of victims and offenders, and the circumstances of the traumata, to identify specific risk factors. RESULTS: Seven hundred and four TBIs were identified. The majority of persons involved were adult and male. The major cause of trauma was assault (98.8%).

The objective of this work was to examine the association between PCB levels in post-mortem human brain tissue and the diagnosis of Parkinson’s disease, as well as the degree of nigral depigmentation. We also sought to determine if this association was more significant when patients were stratified by sex. Post-mortem brain samples from control patients and those diagnosed with Parkinson’s disease were obtained from the Emory University Brain Bank and from the Nun Study. Concentrations of eight prevalent PCB congeners were extracted from post-mortem brain tissue and analyzed using gas chromatography-mass spectrometry. PCB congeners 153 and 180 were significantly elevated in the brains of Parkinson’s disease patients. When stratified by sex, the female Parkinson’s disease group demonstrated significantly elevated concentrations of total PCBs and specifically congeners 138, 153, and 180 compared to controls, whereas PCB concentrations in males were not significantly different between control and Parkinson’s disease groups. In a separate population of women (Nun Study) who had no clinical signs or symptoms of PD, elevated concentrations total PCB and congeners 138, 153 and 180 were also observed in post-mortem brain tissue exhibiting moderate nigral depigmentation compared to subjects with mild or no depigmentation. These quantitative data demonstrate an association between brain PCB levels and Parkinson’s disease-related pathology. Furthermore, these data support epidemiological and laboratory studies reporting a link between PCB exposure and an increased risk for Parkinson’s disease, including greater susceptibility of females.", "title": "Association between polychlorinated biphenyls and Parkinson’s disease neuropathology" }, { "docid": "MED-3939", "text": "Excerpt This Statistical Brief presents data from the Healthcare Cost and Utilization Project (HCUP) on the treatment of TBI in U.S. hospitals in 2004.

The present results show that acute Roundup exposure at low doses (36 ppm, 0.036 g/L) for 30 min induces oxidative stress and activates multiple stress-response pathways leading to Sertoli cell death in prepubertal rat testis. The pesticide increased intracellular Ca(2+) concentration by opening L-type voltage-dependent Ca(2+) channels as well as endoplasmic reticulum IP3 and ryanodine receptors, leading to Ca(2+) overload within the cells, which set off oxidative stress and necrotic cell death. Similarly, 30 min incubation of testis with glyphosate alone (36 ppm) also increased (45)Ca(2+) uptake. These events were prevented by the antioxidants Trolox and ascorbic acid. Activated protein kinase C, phosphatidylinositol 3-kinase, and the mitogen-activated protein kinases such as ERK1/2 and p38MAPK play a role in eliciting Ca(2+) influx and cell death. Roundup decreased the levels of reduced glutathione (GSH) and increased the amounts of thiobarbituric acid-reactive species (TBARS) and protein carbonyls. Also, exposure to glyphosate-Roundup stimulated the activity of glutathione peroxidase, glutathione reductase, glutathione S-transferase, γ-glutamyltransferase, catalase, superoxide dismutase, and glucose-6-phosphate dehydrogenase, supporting downregulated GSH levels. Glyphosate has been described as an endocrine disruptor affecting the male reproductive system; however, the molecular basis of its toxicity remains to be clarified. We propose that Roundup toxicity, implicated in Ca(2+) overload, cell signaling misregulation, stress response of the endoplasmic reticulum, and/or depleted antioxidant defenses, could contribute to Sertoli cell disruption in spermatogenesis that could have an impact on male fertility.

Glyphosate targets the shikimate metabolic pathway, which is found in plants but not in animals. Despite the relative safety of glyphosate, various adverse developmental and reproductive problems have been alleged as a result of exposure in humans and animals. To assess the developmental and reproductive safety of glyphosate, an analysis of the available literature was conducted. Epidemiological and animal reports, as well as studies on mechanisms of action related to possible developmental and reproductive effects of glyphosate, were reviewed. An evaluation of this database found no consistent effects of glyphosate exposure on reproductive health or the developing offspring. Furthermore, no plausible mechanisms of action for such effects were elucidated. Although toxicity was observed in studies that used glyphosate-based formulations, the data strongly suggest that such effects were due to surfactants present in the formulations and not the direct result of glyphosate exposure. To estimate potential human exposure concentrations to glyphosate as a result of working directly with the herbicide, available biomonitoring data were examined. These data demonstrated extremely low human exposures as a result of normal application practices. Furthermore, the estimated exposure concentrations in humans are >500-fold less than the oral reference dose for glyphosate of 2 mg/kg/d set by the U.S. Environmental Protection Agency (U.S. EPA 1993).

Serum albumin (SA) and globin (Gb) adducts were first tested as biomarkers of exposure to PhIP in male Fischer 344 rats given oral doses of 0.1, 0.5, 1 and 10 mg/kg. Blood samples were collected 24 hr after treatment and PhIP released from SA and Gb after acidic hydrolysis was analyzed by gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry. PhIP-SA and Gb adducts increased linearly with the dose. Studies on 35 volunteers with different dietary habits exhibited that diet was a major determinant in the formation of both adducts. PhIP-SA adducts were significantly higher in meat consumers than in vegetarians (6.7 +/- 1.6 and 0.7 +/- 0.3 fmol/mg SA; respectively, mean +/- SE; p = 0.04, Mann-Whitney U test).

MEASUREMENTS: Dental and physical examinations were conducted every 3 to 5 years. Diet was assessed using food frequency questionnaires (FFQs). Mean follow-up was 15 years (range: 2-24 years). Periodontal disease progression on each tooth was defined as alveolar bone loss (ABL) advancement of 40% or more, probing pocket depth (PPD) of 2 mm or more, or tooth loss.

The main outcome measure was the change in the rate of atrophy of the whole brain assessed by serial volumetric MRI scans. Results A total of 168 participants (85 in active treatment group; 83 receiving placebo) completed the MRI section of the trial.

Design: Free-living individuals with type 2 diabetes were randomly assigned to a low-fat vegan diet (n = 49) or a diet following 2003 American Diabetes Association guidelines (conventional, n = 50) for 74 wk. Glycated hemoglobin (Hb A1c) and plasma lipids were assessed at weeks 0, 11, 22, 35, 48, 61, and 74. Weight was measured at weeks 0, 22, and 74. Results: Weight loss was significant within each diet group but not significantly different between groups (−4.4 kg in the vegan group and −3.0 kg in the conventional diet group, P = 0.25) and related significantly to Hb A1c changes (r = 0.50, P = 0.001).

Inositol is also a natural constituent possessing moderate anticancer activity. The most consistent and best anticancer results were obtained from the combination of IP6 plus inositol. In addition to reducing cell proliferation, IP6 increases differentiation of malignant cells, often resulting in a reversion to normal phenotype. Exogenously administered IP6 is rapidly taken into the cells and dephosphorylated to lower-phosphate inositol phosphates, which further interfere with signal transduction pathways and cell cycle arrest. Enhanced immunity and antioxidant properties can also contribute to tumor cell destruction. However, the molecular mechanisms underlying this anticancer action are not fully understood. Because it is abundantly present in regular diet, efficiently absorbed from the gastrointestinal tract, and safe, IP6 holds great promise in our strategies for the prevention and treatment of cancer. IP6 plus inositol enhances the anticancer effect of conventional chemotherapy, controls cancer metastases, and improves the quality of life, as shown in a pilot clinical trial. The data strongly argue for the use of IP6 plus inositol in our strategies for cancer prevention and treatment.

METHODS: A total of 47 overweight hyperlipidemic men and women consumed either (1) a low-carbohydrate (26% of total calories), high-vegetable protein (31% from gluten, soy, nuts, fruit, vegetables, and cereals), and vegetable oil (43%) plant-based diet or (2) a high-carbohydrate lacto-ovo vegetarian diet (58% carbohydrate, 16% protein, and 25% fat) for 4 weeks each in a parallel study design.

Urinary incontinence was defined using a standard questionnaire with Incontinence Severity Index scores 3 or greater categorized as moderate to severe. Structured dietary recall was used to determine caffeine consumption (mg per day), water intake (gm per day) and total dietary moisture (gm per day). Stepwise multivariable logistic regression models were used to assess the association between caffeine intake at or above the 75th and 90th percentiles and moderate to severe urinary incontinence, controlling for potential confounders, urinary incontinence risk factors and prostate conditions in men age 40 years or older. RESULTS: Of the 5,297 men 3,960 (75%) were 20 years old or older with complete data. Among these men the prevalence of any urinary incontinence was 12.9% and moderate to severe urinary incontinence was 4.4%. Mean caffeine intake was 169 mg per day. Caffeine intake at the upper 75th percentile (234 mg or more daily) and 90th percentile (392 mg or more per day) was significantly associated with having moderate to severe urinary incontinence (1.72, 95% 1.18-2.49 and 2.08, 95% 1.15-3.77, respectively). In addition, after adjusting for prostate conditions, the effect size for the association between caffeine intake and moderate to severe urinary incontinence remained.

Recent work suggested a possible correlation between pathological features such as frequency of basophilic inclusions in neurons and rate of clinical decline, other studies have revealed a discrepancy between the upper motor neuron features detected clinically and the associated pathology. The purpose of this study was to describe the pathological features associated with more recently discovered FUS mutations and reinvestigate those with well recognised mutations in an attempt to correlate the pathology with mutation and/or clinical phenotype. The brains and spinal cords of seven cases of ALS-FUS were examined neuropathologically, including cases with the newly described p. K510E mutation and a case with both a known p. P525L mutation in the FUS gene and a truncating p. Y374X mutation in the TARDBP gene. RESULTS The neuropathology in all cases revealed basophilic and FUS inclusions in the cord. The density and type of inclusions varied markedly between cases, but did not allow a clear correlation with clinical progression. Only one case showed significant motor cortical pathology despite the upper motor neuron clinical features being evident in 4 patients. The case with both a FUS and TARDBP mutation revealed FUS positive inclusions but no TDP-43 pathology. Instead there were unusual p62 positive, FUS negative neuronal and glial inclusions as well as dot-like neurites. CONCLUSIONS The study confirms cases of ALS-FUS to be mainly a lower motor neuron disease and to have pathology that does not appear to neatly correlate with clinical features or genetics.

We hypothesized that combinatorial expression of neural-lineage-specific transcription factors could directly convert fibroblasts into neurons.

Human mesenchymal cells isolated from the Wharton's jelly of the umbilical cord (HUMSCs), which can be easily obtained and processed compared with embryonic and bone marrow stem cells, possess stem cell properties. HUMSCs may be a valuable source for the generation of islets. METHODOLOGY AND PRINCIPAL FINDINGS HUMSCs were induced to transform into islet-like cell clusters in vitro through stepwise culturing in neuron-conditioned medium. To assess the functional stability of the islet-like cell clusters in vivo, these cell clusters were transplanted into the liver of streptozotocin-induced diabetic rats via laparotomy. Glucose tolerance was measured on week 12 after transplantation accompanied with immunohistochemistry and electron microscopy analysis. These islet-like cell clusters were shown to contain human C-peptide and release human insulin in response to physiological glucose levels. Real-time RT-PCR detected the expressions of insulin and other pancreatic beta-cell-related genes (Pdx1, Hlxb9, Nkx2.2, Nkx6.1, and Glut-2) in these islet-like cell clusters. The hyperglycemia and glucose intolerance in streptozotocin-induced diabetic rats was significantly alleviated after xenotransplantation of islet-like cell clusters, without the use of immunosuppressants. In addition to the existence of islet-like cell clusters in the liver, some special fused liver cells were also found, which characterized by human insulin and nuclei-positive staining and possessing secretory granules. CONCLUSIONS AND SIGNIFICANCE In this study, we successfully differentiate HUMSCs into mature islet-like cell clusters, and these islet-like cell clusters possess insulin-producing ability in vitro and in vivo.

However, little is known about the underlying mechanisms of their malfunction. Although ErbB4 is enriched in GABAergic interneurons, the role of NRG1 in excitatory synapse formation in these neurons remains poorly understood. We showed that NRG1 increased both the number and size of PSD-95 puncta and the frequency and amplitude of miniature EPSCs (mEPSCs) in GABAergic interneurons, indicating that NRG1 stimulates the formation of new synapses and strengthens existing synapses. In contrast, NRG1 treatment had no effect on either the number or size of excitatory synapses in glutamatergic neurons, suggesting its synaptogenic effect is specific to GABAergic interneurons. Ecto-ErbB4 treatment diminished both the number and size of excitatory synapses, suggesting that endogenous NRG1 may be critical for basal synapse formation. NRG1 could stimulate the stability of PSD-95 in the manner that requires tyrosine kinase activity of ErbB4. Finally, deletion of ErbB4 in parvalbumin-positive interneurons led to reduced frequency and amplitude of mEPSCs, providing in vivo evidence that ErbB4 is important in excitatory synaptogenesis in interneurons. Together, our findings suggested a novel synaptogenic role of NRG1 in excitatory synapse development, possibly via stabilizing PSD-95, and this effect is specific to GABAergic interneurons.

In addition, biochemical and pathological changes in the cord may worsen after injury. To explain these phenomena, the concept of the secondary injury has evolved for which numerous pathophysiological mechanisms have been postulated. This paper reviews the concept of secondary injury with special emphasis on vascular mechanisms. Evidence is presented to support the theory of secondary injury and the hypothesis that a key mechanism is posttraumatic ischemia with resultant infarction of the spinal cord. Evidence for the role of vascular mechanisms has been obtained from a variety of models of acute spinal cord injury in several species. Many different angiographic methods have been used for assessing microcirculation of the cord and for measuring spinal cord blood flow after trauma. With these techniques, the major systemic and local vascular effects of acute spinal cord injury have been identified and implicated in the etiology of secondary injury. The systemic effects of acute spinal cord injury include hypotension and reduced cardiac output. The local effects include loss of autoregulation in the injured segment of the spinal cord and a marked reduction of the microcirculation in both gray and white matter, especially in hemorrhagic regions and in adjacent zones. The microcirculatory loss extends for a considerable distance proximal and distal to the site of injury. Many studies have shown a dose-dependent reduction of spinal cord blood flow varying with the severity of injury, and a reduction of spinal cord blood flow which worsens with time after injury. The functional deficits due to acute spinal cord injury have been measured electrophysiologically with techniques such as motor and somatosensory evoked potentials and have been found proportional to the degree of posttraumatic ischemia. The histological effects include early hemorrhagic necrosis leading to major infarction at the injury site. These posttraumatic vascular effects can be treated. Systemic normotension can be restored with volume expansion or vasopressors, and spinal cord blood flow can be improved with dopamine, steroids, nimodipine, or volume expansion. The combination of nimodipine and volume expansion improves posttraumatic spinal cord blood flow and spinal cord function measured by evoked potentials.

Cognitive deficits in DS result from perturbations of normal cellular processes both during development and in adult tissues, but the mechanisms underlying DS etiology remain poorly understood. To assess the ability of induced pluripotent stem cells (iPSCs) to model DS phenotypes, as a prototypical complex human disease, we generated bona fide DS and wild-type (WT) nonviral iPSCs by episomal reprogramming. DS iPSCs selectively overexpressed chromosome 21 genes, consistent with gene dosage, which was associated with deregulation of thousands of genes throughout the genome. DS and WT iPSCs were neurally converted at >95% efficiency and had remarkably similar lineage potency, differentiation kinetics, proliferation, and axon extension at early time points. However, at later time points DS cultures showed a twofold bias toward glial lineages. Moreover, DS neural cultures were up to two times more sensitive to oxidative stress-induced apoptosis, and this could be prevented by the antioxidant N-acetylcysteine. Our results reveal a striking complexity in the genetic alterations caused by trisomy 21 that are likely to underlie DS developmental phenotypes, and indicate a central role for defective early glial development in establishing developmental defects in DS brains. Furthermore, oxidative stress sensitivity is likely to contribute to the accelerated neurodegeneration seen in DS, and we provide proof of concept for screening corrective therapeutics using DS iPSCs and their derivatives.

The other replies do not appear to address this situation. Suppose that Apple is trading at $96 and you sell a put option with a strike price of $95 for some future delivery date - say August 2016. The option contract is for 100 shares and you sell the contract for a premium of $3.20. When you sell the option your account will be credited with the premium and debited with the broker commission. The premium you receive will be $320 = 100 x $3.20. The commission you pay will depend on you broker. Now suppose that the price of Apple drops to $90 and your option is exercised, either on expiry or prior to expiry. Then you would be obliged to take delivery of 100 Apple shares at the contracted option strike price of $95 costing you $9,500 plus broker commission. If you immediately sell the Apple shares you have purchased under your contract obligations, then assuming you sell the shares at the current market price of $90 you would realise a loss of $500 ( = 100x($95-$90) )plus commission. Since you received a premium of $320 when you sold the put option, your net loss would be $500-$320 = $180 plus any commissions paid to your broker. Now let's look at the case of selling a call option. Again assume that the price of Apple is $96 and you sell a call option for 100 shares with a strike price of $97 for a premium of $3.60. The premium you receive would be $360 = 100 x $3.60. You would also be debited for commission by your broker. Now suppose that the price of Apple shares rises to $101 and your option is exercised. Then you would be obliged to deliver 100 Apple shares to the party exercising the option at the contracted strike price of $97. If you did not own the shares to effect delivery, then you would need to purchase those shares in the market at the current market price of $101, and then sell them to the party exercising the option at the strike price of $97. This would realise an immediate loss of $400 = 100 x ($101-$97) plus any commission payable. If you did own the shares, then you would simply deliver them and possibly pay some commission or a delivery fee to your broker. Since you received $360 when you sold the option, your net loss would be $40 = $400-$360 plus any commission and fees payable to the broker. It is important to understand that in addition to these accounting items, short option positions carry with them a \"\"margin\"\" requirement. You will need to maintain a margin deposit to show \"\"good faith\"\" so long as the short option position is open.

Assume the strike date, or date of settlement, is 6 months from now. Thus Abby is long one put option and John is short one put option (the writer of the option is short the option). On settlement date, let's assume two different scenarios: (1) If the price of the stock decreases by $50, then the put that Abby bought is 'in the money'. Abby's profit can be calculated as being strike price 190 - current stock price 150 - premium paid 5 = $35 So not including any transaction fees, that is a $35 dollar return on a $5 investment. (2) If the price of the stock increases by $50, then the put that Abby bought is worthless and her loss was 100%, or her entire $5 premium.

[ { "docid": "440458", "text": "1) Yes, both of your scenarios would lead to earning $10 on the transaction, at the strike date. If you purchased both of them (call it Scenario 3), you would make $20. 2) As to why this transaction may not be possible, consider the following: The Call and Put pricing you describe may not be available. What you have actually created is called 'arbitrage' - 2 identical assets can be bought and sold at different prices, leading to a zero-risk gain for the investor. In the real marketplace, if an option to buy asset X in January cost $90, would an option to sell asset X in January provide $110? Without adding additional complexity about the features of asset x or the features of the options, buying a Call option is the same as selling a Put option [well, when selling a Put option you don't have the ability to choose whether the option is exercised, meaning buying options has value that selling options does not, but ignore that for a moment]. That means that you have arranged a marketplace where you would buy a Call option for only $90, but the seller of that same option would somehow receive $110. For added clarity, consider the following: What if, in your example, the future price ended up being $200? Then, you could exercise your call option, buying a share for $90, selling it for $200, making $110 profit. You would not exercise your put option, making your total profit $110. Now consider: What if, in your example, the future price ended up being $10? You would buy for $10, exercise your put option and sell for $110, making a profit of $100. You would not exercise your call option, making your total profit $100. This highlights that if your initial assumptions existed, you would earn money (at least $20, and at most, unlimited based on a skyrocketing price compared to your $90 put option) regardless of the future price. Therefore such a scenario would not exist in the initial pricing of the options. Now perhaps there is an initial fee involved with the options, where the buyer or seller pays extra money up-front, regardless of the future price. That is a different scenario, and gets into the actual nature of options, where investors will arrange multiple simultaneous transactions in order to limit risk and retain reward within a certain band of future prices. As pointed out by @Nick R, this fee would be very significant, for a call option which had a price set below the current price. Typically, options are sold 'out of the money' initially, which means that at the current share price (at the time the option is purchased), executing the option would lose you money. If you purchase an 'in the money' option, the transaction cost initially would by higher than any apparent gain you might have by immediately executing the option. For a more realistic Options example, assume that it costs $15 initially to buy either the Call option, or the Put option. In that case, after buying both options as listed in your scenarios you would earn a profit if the share price exceeded $120 [The $120 sale price less the $90 call option = $30, which is your total fee initially], or dropped below $80 [The $110 Put price less the $80 purchase price = $30]. This type of transaction implies that you expect the price to either swing up, or swing down, but not fall within the band between $80-$120. Perhaps you might do this if there was an upcoming election or other known event, which might be a failure or success, and you think the market has not properly accounted for either scenario in advance. I will leave further discussion on that topic [arranging options of different prices to create specific bands of profitability / loss] to another answer (or other questions which likely already exist on this site, or in fact, other resources), because it gets more complicated after that point, and is outside the root of your question.", "title": "" }, { "docid": "573077", "text": "\"Being \"\"Long\"\" something means you own it. Being \"\"Short\"\" something means you have created an obligation that you have sold to someone else. If I am long 100 shares of MSFT, that means that I possess 100 shares of MSFT. If I am short 100 shares of MSFT, that means that my broker let me borrow 100 shares of MSFT, and I chose to sell them. While I am short 100 shares of MSFT, I owe 100 shares of MSFT to my broker whenever he demands them back. Until he demands them back, I owe interest on the value of those 100 shares. You short a stock when you feel it is about to drop in price. The idea there is that if MSFT is at $50 and I short it, I borrow 100 shares from my broker and sell for $5000. If MSFT falls to $48 the next day, I buy back the 100 shares and give them back to my broker. I pocket the difference ($50 - $48 = $2/share x 100 shares = $200), minus interest owed. Call and Put options. People manage the risk of owning a stock or speculate on the future move of a stock by buying and selling calls and puts. Call and Put options have 3 important components. The stock symbol they are actionable against (MSFT in this case), the \"\"strike price\"\" - $52 in this case, and an expiration, June. If you buy a MSFT June $52 Call, you are buying the right to purchase MSFT stock before June options expiration (3rd Saturday of the month). They are priced per share (let's say this one cost $0.10/share), and sold in 100 share blocks called a \"\"contract\"\". If you buy 1 MSFT June $52 call in this scenario, it would cost you 100 shares x $0.10/share = $10. If you own this call and the stock spikes to $56 before June, you may exercise your right to purchase this stock (for $52), then immediately sell the stock (at the current price of $56) for a profit of $4 / share ($400 in this case), minus commissions. This is an overly simplified view of this transaction, as this rarely happens, but I have explained it so you understand the value of the option. Typically the exercise of the option is not used, but the option is sold to another party for an equivalent value. You can also sell a Call. Let's say you own 100 shares of MSFT and you would like to make an extra $0.10 a share because you DON'T think the stock price will be up to $52/share by the end of June. So you go to your online brokerage and sell one contract, and receive the $0.10 premium per share, being $10. If the end of June comes and nobody exercises the option you sold, you get to keep the $10 as pure profit (minus commission)! If they do exercise their option, your broker makes you sell your 100 shares of MSFT to that party for the $52 price. If the stock shot up to $56, you don't get to gain from that price move, as you have already committed to selling it to somebody at the $52 price. Again, this exercise scenario is overly simplified, but you should understand the process. A Put is the opposite of a Call. If you own 100 shares of MSFT, and you fear a fall in price, you may buy a PUT with a strike price at your threshold of pain. You might buy a $48 June MSFT Put because you fear the stock falling before June. If the stock does fall below the $48, you are guaranteed that somebody will buy yours at $48, limiting your loss. You will have paid a premium for this right (maybe $0.52/share for example). If the stock never gets down to $48 at the end of June, your option to sell is then worthless, as who would sell their stock at $48 when the market will pay you more? Owning a Put can be treated like owning insurance on the stock from a loss in stock price. Alternatively, if you think there is no way possible it will get down to $48 before the end of June, you may SELL a $48 MSFT June Put. HOWEVER, if the stock does dip down below $48, somebody will exercise their option and force you to buy their stock for $48. Imagine a scenario that MSFT drops to $30 on some drastically terrible news. While everybody else may buy the stock at $30, you are obligated to buy shares for $48. Not good! When you sold the option, somebody paid you a premium for buying that right from you. Often times you will always keep this premium. Sometimes though, you will have to buy a stock at a steep price compared to market. Now options strategies are combinations of buying and selling calls and puts on the same stock. Example -- I could buy a $52 MSFT June Call, and sell a $55 MSFT June Call. I would pay money for the $52 Call that I am long, and receive money for the $55 Call that I am short. The money I receive from the short $55 Call helps offset the cost of buying the $52 Call. If the stock were to go up, I would enjoy the profit within in $52-$55 range, essentially, maxing out my profit at $3/share - what the long/short call spread cost me. There are dozens of strategies of mixing and matching long and short calls and puts depending on what you expect the stock to do, and what you want to profit or protect yourself from. A derivative is any financial device that is derived from some other factor. Options are one of the most simple types of derivatives. The value of the option is derived from the real stock price. Bingo? That's a derivative. Lotto? That is also a derivative. Power companies buy weather derivatives to hedge their energy requirements. There are people selling derivatives based on the number of sunny days in Omaha. Remember those calls and puts on stock prices? There are people that sell calls and puts based on the number of sunny days in Omaha. Sounds kind of ridiculous -- but now imagine that you are a solar power company that gets \"\"free\"\" electricity from the sun and they sell that to their customers. On cloudy days, the solar power company is still on the hook to provide energy to their customers, but they must buy it from a more expensive source. If they own the \"\"Sunny Days in Omaha\"\" derivative, they can make money for every cloudy day over the annual average, thus, hedging their obligation for providing more expensive electricity on cloudy days. For that derivative to work, somebody in the derivative market puts a price on what he believes the odds are of too many cloudy days happening, and somebody who wants to protect his interests from an over abundance of cloudy days purchases this derivative. The energy company buying this derivative has a known cost for the cost of the derivative and works this into their business model. Knowing that they will be compensated for any excessive cloudy days allows them to stabilize their pricing and reduce their risk. The person selling the derivative profits if the number of sunny days is higher than average. The people selling these types of derivatives study the weather in order to make their offers appropriately. This particular example is a fictitious one (I don't believe there is a derivative called \"\"Sunny days in Omaha\"\"), but the concept is real, and the derivatives are based on anything from sunny days, to BLS unemployment statistics, to the apartment vacancy rate of NYC, to the cost of a gallon of milk in Maine. For every situation, somebody is looking to protect themselves from something, and somebody else believes they can profit from it. Now these examples are highly simplified, many derivatives are highly technical, comprised of multiple indicators as a part of its risk profile, and extremely difficult to explain. These things might sound ridiculous, but if you ran a lemonade stand in Omaha, that sunny days derivative just might be your best friend...\"", "title": "" }, { "docid": "154989", "text": "\"Whether or not you make money here depends on whether you are buying or selling the option when you open your position. You certainly would not make money in the scenario where you are buying options at the open. If fact you would end up loosing quite a lot of money. You do not specify whether you are buying or selling the options, so let's assume that you are buying both the call and the put. We'll look a profitable trade at the bottom of my answer. Buying an in-the-money Call option with a strike price of $90 when the underlying asset price is $150 would cost you a small fraction over $6000 = (100 x $60) since the intrinsic value value of the option is $60. Add to this cost any commission charged by your broker. Buying an out-of-the-money Put option with a strike price of $110 when the underlying asset price is $150 would cost you a \"\"small\"\" premium - lets say a premium of something like $0.50. The option has no intrinsic value, only time value and a volatility value, so the exact cost would depend on the time to expiry and the implied volatility of the underlying asset. Since the strike price is \"\"well out of the money\"\", being about 27% below the underlying asset price, the premium would be small. So, assuming the premium of $0.50, you would pay $50 for the option plus any commission applicable. The cash settlement on expiry, with an underlying settlement price of $100, would be a premium of $10 for each of the two options, so you would receive cash of 100 x ($10 + $10) = $2000, less any commission applicable. However, you have paid $6000 + $50 to purchase the options, so you realise a net loss of $6050 - $2000 = $4050 plus any commissions applicable. Thus, you would make a profit on the put option, but you would realise a very large loss on the call option. On the other hand, if you open your position by selling the call option and buying the put option, then you would make money. For the sale of the call option you would receive about $6000. For the purchase of the put option you would pay about $50. On settlement, you would pay $1000 to buy back the call option and you would receive about $1000 when selling the put option. Thus you net profit would be about ($6000 - $1000) for the call position, and ($1000 - $50) for the put position.

You would not lose the amount you paid to buy the shares. Naked Call Option Suppose take a naked call option position by selling a call option. Since there is no limit on how high the price of the underlying share can go, you can be forced to either buy back the option at a very high price, or, in the case that the option is exercised, you can be force. to buy the underlying shares at a very high price and then sell them to the option holder at a very low price. For example, suppose you sell an Apple call option with a strike price of $100 at a premium of $2.50, and for this you receive a payment of $250. Now, if the price of Apple skyrockets to, say, $1000, then you would either have to buy back the option for about $90,000 = 100 x ($1000-$100), or, if the holder exercised the option, then you would need to buy 100 Apple shares at the market price of $1000 per share, costing you $100,000, and then sell them to the option holder at the strike price of $100 for $10,000 = 100 x $100. In either case, you would show a loss of $90,000 on the share transaction, which would be slightly offset by a $250 credit for the premium you received selling the call. There is no limit on the potential loss since there is no limit on how high the underlying share price can go. Covered Call Option Consider now the case of a covered call option. Since you hold the underlying shares, any loss you make on the option position would be \"\"covered\"\" by the profit you make on the underlying shares. Again, suppose you own 100 Apple shares and sell a call option with a strike price of $100 at a premium of $2.50 to earn a payment of $250. If the price of Apple skyrockets to $1000, then there are again two possible scenarios. One, you buy back the option at a premium of about $900 costing you $90,000. In order to cover this cost you would then sell your 100 Apple shares at the market price of $1000 per share to realise $100,000 = 100 x $1000. On the other hand, if your option is exercised, then you would deliver your 100 Apple shares to the option holder at the contracted strike price of $100 per share, thus receiving just $10,000 = 100 x $100.

Notice that for an American put you will most likely be better off selling the put when the price of the underlying falls than exercising it. That way you make the money you would have made by exercising plus whatever optional value the put still contains. That is true unless the time value of money is greater than the optional (insurance) value. Since the time value of money is currently exceptionally low, this is unlikely. Anyway, if you sell the option instead of exercising, you don't need to own any shares at all. Even if you do exercise, you can just buy them on the market and sell right away so I wouldn't worry about what you happen to be holding. The rules for what you can trade with a cash instead of a margin account vary by broker, I think. You can usually buy puts and calls in a cash account, but more advanced strategies, such as writing options, are prohibited.

So if you immediately sell 120 shares at $25, you have taxable income on the gain for those shares (120*($25-$17)). Either selling immediately or holding for the long term period (12-18 mo) can be advantageous, just in different ways. Selling immediately avoids a risk of a decline in the price of the stock, and allows you to invest elsewhere and earn income on the proceeds for the next 12-18 months that you would not otherwise have had. The downside is that all of your gain ($25-$17 per share) is taxed as ordinary income. Holding for the full period is advantageous in that only the discount (15% of $20 or $25) will be taxed as ordinary income and the rest of the gain (sell price minus $20 or $25) will be taxed at long-term capital gain tax rates, which generally are lower than ordinary rates (all taxes are due in the year you do sell). The catch is you will sell at different price, higher or lower, and thus have a risk of loss (or gain). You will never be (Federally) double taxed in any scenario. The $3000 you put in will not be taxed after all is sold, as it is a return of your capital investment. All money you receive in excess of the $3000 will be taxed, in all scenarios, just potentially at different rates, ordinary or capital gain.

You pay me a fee for the right to put the stock (or other underlying security) in my hands if you want to. That happens on a specific date (the strike date) and a specified price (the strike price). You can decide not to exercise that right, but I must follow through and let you sell it to me if you want to. Put options can be used by the purchaser to cap losses. For example: You purchase a PUT option for GE Oct19 13.00 from me. On October 19th, you can make me let you sell your GE stock to me for $13.00 a share. If the price for GE has fallen to $12.00, that would be a good idea. If its now at $15.00 a share, you will probably keep the GE or sell it at the current market price. Call options are contracts to buy. The same idea only in the other direction: You pay me a fee for the right to call the stock away from me. Calls also have a strike date and strike price. Like a put, you can choose not to exercises it. You can choose to buy the stock from me (on the strike date for the strike price), but I have to let you buy it from me if you want to. For example: You purchase a CALL option for GE Oct19 16.00 option from me. On October 19th, you can buy my GE stock from me for $16.00 a share.

Hedge funds do this by hedging, that is, buying a stock that they think is strong and selling short a paired stock that is weak. If you hold, say, a strong retail company in your portfolio, you might sell short an equal weight of a weak retail company. These are like buying insurance on your portfolio. If you own 300 shares of XYZ, currently trading at $68, you buy puts at a level at a strike price that lets you sleep at night. For example, you might buy 3 XYZ 6-month puts with a strike price of $60. A disadvantage is that the puts are wasting assets, that is, their time premium (which you paid for at the outset) becomes zero at expiration. (This is why it is like insurance. You wouldn't complain that your insurance premium was lost when you purchase insurance on your house and the house doesn't burn down, would you? Of course not. The purpose of the insurance is to protect your investment.) Note that as these puts are married, they only protect your portfolio. Instead of profiting from a correction, you would merely protect your portfolio during a correction. (No small feat!) If your portfolio is similar to the market, you can buy S&P index puts. If your market reflects a lot of technology, you can buy technology sector puts. Say you have a portfolio of $80K that reflects the market. You could buy out-of-the-market puts (again reflecting your tolerance for loss). Any losses in your portfolio after the puts go in-the-money would be (more or less) offset by gains in the puts. An advantage is that the bid/ask spread is smaller for the S&P. You would pay less for the protection. Also, the S&P puts are cash settled (meaning you get money put in your account on the business day after expiration day). A disadvantage is that the puts do not linearly go up as the market drops. (Delta hedging is a big deal in and of itself.) Another disadvantage is that they are wasting assets (see the Married puts section, previous). While the S&P puts can be used to maintain your market portfolio in the midst of a correction, you could purchase more puts than needed. If you had correctly timed the market, then your portfolio with puts would increase. (Your mileage may vary; some have predicted an imminent market crash way too often.) Collars involve selling out-of-the-money calls and using the premiums to buy out-of-the-money puts. There are many varieties of collars, but the most straightforward is to sell 1 call and buy 1 put for every 100 shares. (This can also be done for index puts and calls.) This has the effect of simultaneously: You get your insurance for almost free. But again, it is protecting your portfolio. As the name implies, you make money when the market goes bearish. Bear put spreads involve buying puts at a close strike price and selling an equal number of puts at a lower strike price than the first. You have a defined maximum loss (the premium you paid for the higher put minus the premium you received for the lower put). You have a defined maximum gain (the difference between strikes minus the defined maximum loss). Buy S&P 500 index puts. If you buy deep out-of-the-money puts, it won't cost much, but you have little probability of it paying off. But if they go in-the-money, there could be a sizable payoff. This is similar to putting one chip on red 18 on the roulette wheel. But rather than paying off 35:1, it is a variable payoff. If you're $1 in the money, you just get $100. If you're $12 in the money, you have a $1200 payoff. If you buy at-the-money puts, it will cost a lot, and your probability will be about 1 in 2 that you will pay off. In our roulette analogy, this is like putting 30 chips on the Even bet of the roulette wheel. The variable payoff is as in the previous paragraph. But you're more likely to get a payoff. And you will lose it all of the roulette ball lands on an Odd number, 0, or 00. (That is, the underlying of your put goes up or stays the same.) If your research shows you what good stocks to buy, it may also tell you which stocks are ripe for a fall. You could short-sell these stocks or buy puts on them. Similar to short-selling stocks or buying puts, you could sell short overpriced sectors or buy puts on them.

Alternatively, you could buy a put option on it. Even more risky, you could sell a (naked) call option on it. i.e. you receive the option premium up front, and if it expires worthless you keep the money. Of course, if gold goes up, you're on the hook. (Don't do this.) (the \"\"Don't do this\"\" was added by Chris W. Rea.

Your broker doesn't own the calls you sold, and can't elect to exercise someone else's calls. Your broker can take action to liquidate positions when you are in margin calls, but the scenario you describe wouldn't generate them: If you are long stock, and short calls, the calls are covered, and have no margin requirement. The stock is the only collateral you need, and you can have the position on in a cash (non-margin) account. So, assuming you haven't bought other things on margin that have gone south and are generating calls, your broker has no right to do anything to you.

In that scenario, you make $21, your maximum possible return (since you bought the stock at $100, collected $1 premium, and sold it for $120.

The reason they usually won't is that most options trade above their intrinsic value (the amount that they're in the money). In your example, the options aren't in the money at all. The stock is trading at 120, and the option gives the owner the right to buy at 120.* Put another way, exercising the option lets the owner buy the stock for the exact same price anyone with no options can in the market.

For example, if the price is $100 and you want to sell if the price rises to $110, then you can simply put a limit order to sell at $110. The order will be placed in the market and when the price reaches $110 your order will be executed. If the price gaps at the open to $111, then you would end up selling for $111. In other words you will get a minimum of $110 per share. A stop limit order is where you put a stop loss order, which when it gets triggered, will place a limit order in the market for you. For example, you want to limit your losses by placing a stop loss order if the price drops to $90. If you chose a market order with your stop loss as soon as the price hits $90 your stop loss would be triggered and the shares would sell at the next available price, usually at $90, but could be less if the market gaps down past $90. If on the other hand you placed a limit order at $89.50 with your stop loss, when the stop loss order gets triggered at $90 your limit order will be placed into the market to sell at $89.50. So you would get a minimum of $89.50 per share, however, if the market gaps down below $89.50 your order will be placed onto the market but it won't sell, unless the price goes back to or above $89.50.

It is important to understand that futures contracts are tradeable instruments, meaning that you are free to sell (or buy back) your contract at any time before the expiry date. For example, if you buy 1 \"\"lot\"\" (1 contract) of a gold future on the Comex exchange for the contract month of December 2016, then you entering into a contract to buy 100 ounces (the contract size) of gold at the price at which you buy the contract - not the spot price on the day of expiry when the contract comes to maturity. The December 2016 gold futures contract has an expiry date of 28 December. You are free to trade this contract at any time before its expiry by selling it back to another market participant. If you sell the contract at a price higher than you have purchased it, then you will realise a profit of 100 times the difference between the price you bought the contract and the price you sold the contract, where 100 is the contract size of the gold contract. Similarly, if you sell the contract at a price lower than the price you have purchased it, then you will realise a loss. (Commissions paid will also effect your net profit or loss). If you hold your contract until the expiry date and exercise your contract by taking (or making) delivery, then you are obliged to buy (or sell) 100 ounces of gold at the price at which you bought (or sold) the contract - not the current spot price. So long as your contract is \"\"open\"\" (i.e., prior to the expiry date and so long as you own the contract) you are required to make a \"\"good faith deposit\"\" to show that you intend to honour your contractual obligations. This deposit is usually called \"\"initial margin\"\". Typically, the initial margin amount will be about 2% of the total contract value for the gold contract. So if you buy (or sell) one contract for 100 ounces of gold at, say, $1275 an ounce, then the total contract value will be $127,500 and your deposit requirement would be about $2,500. The initial margin is returned to you when you sell (or buy) back your futures contract, or when you exercise your contract on expiry. In addition to initial margin, you will be required to maintain a second type of margin called \"\"variation margin\"\". The variation margin is the running profit or loss you are showing on your open contract. For the sake of simplicity, lets look only at the case where you have purchased a futures contract. If the futures price is higher than your contract (buy) price, then you are showing a profit on your current position and this profit (the variation margin) will be used to offset your initial margin requirement. Conversely, if the futures price has dropped below your contracted (buy) price, then you will be showing a loss on your open position and this loss (the variation margin) will be added to your initial margin and you will be called to put up more money in order to show good faith that you intend to honour your obligations. Note that neither the initial margin nor the variation margin are accounting items. In other words, these are not postings that are debited or credited to the ledger in your trading account.

This includes calls with strikes above the current underlying price, and puts with strikes below it. A heck of a lot of options. If an option with value was somehow left to expire, it was probably a mistake, or else the transaction costs outweighed the value remaining; not quite worthless, but not \"\"worth it\"\" either. The less obvious: An option with value can be cancelled any time before expiration.

Similarly, if a loss, he may want to take the loss sooner. In both cases, his capital is freed up and he can take another position. And — this is the key part — the other end matched up with that option sale is often a buyer that had created (written) exactly such an option contract in the first place – the option writer – and who is looking to get out of his position. Option writers are the traders responsible, in the first place, for creating options and increasing the \"\"open interest.\"\" Anybody with the right kind and level of options trading account can do this. A trader that writes an option does so by instructing his broker to \"\"sell to open\"\" a new instance of the option. The trader then has a short position (negative quantity) in that option, and all the while may be subject to the obligations that match the option's exercise rights. The only way for the option writer to get out of that short position and its obligations are these: Not by choice: To get assigned. That is to say: a buyer exercised the option. The writer has to fulfill his obligation by delivering the underlying (if a call) to the option holder, or buying the underlying (if a put) from the option holder. Not by choice: The option expires worthless. This is the ideal scenario for a writer because 100% of the premium received (less transaction costs) is profit. By choice: The writer is free to buy back exactly the same kind of option before expiry using a \"\"buy to close\"\" order with their broker.

The share lender comes calling for their share and you have to close the position at $1,000 for a loss of $990.

Thus, if the amount of equity left gets too low, the broker has a legal obligation to close the position which can be selling purchased shares or buying back borrowed shares depending on if this is a long or short position respectively. Investopedia has an example that they walk through as the call is where you are asked to either put in more money to the account or the position may be closed because the broker wants their money back. What is Maintenance Margin? A maintenance margin is the required amount of securities an investor must hold in his account if he either purchases shares on margin, or if he sells shares short. If an investor's margin balance falls below the set maintenance margin, the investor would then need to contribute additional funds to the account or liquidate stocks in the account to bring the account back to the initial margin requirement. This request is known as a margin call. As discussed previously, the Federal Reserve Board sets the initial margin requirement (currently at 50%). The Federal Reserve Board also sets the maintenance margin. The maintenance margin, the amount of equity an investor needs to hold in his account if he buys stock on margin or sells shares short, is 25%. Keep in mind, however, that this 25% level is the minimum level set, brokerage firms can increase, but not decrease this level as they desire. Example: Determining when a margin call would occur. Assume that an investor had purchased 500 shares of Newco's stock. The shares were trading at $50 when the transaction was executed. The initial margin requirement on the account was 70% and the maintenance margin is 30%. Assume no transaction costs. Determine the price at which the investor will receive a margin call. Answer: Calculate the price as follows: $50 (1- 0.70) = $21.43 1 - 0.30 A margin call would be received when the price of Newco's stock fell below $21.43 per share. At that time, the investor would either need to deposit additional funds or liquidate shares to satisfy the initial margin requirement. Most people don't want \"\"Margin Calls\"\" but stocks may move in unexpected ways and this is where there are mechanisms to limit losses, especially for the brokerage firm that wants to make as much money as possible. Cancel what trade? No, the broker will close the position if the requirement isn't kept. Basically think of this as a way for the broker to get their money back if necessary while following federal rules. This would be selling in a long position or buying in a short sale situation.

In a nutshell, you are buying call options with current strike price (at-the-money) and sell call options with higher strike price (out-of-the-money), all with the same expiry dates. The only reason to also sell call options here is to recover your premium paid for the other call options. If you are comfortable paying that premium, you just buy the call options without selling the others. In case your stock will rise moderately to a price between the two strike prices, your call option will rise together with your stock, so you will be faster to recover your money. This is the main reason it is called Repair. If you have sold any call options, as the price rises, you have to be careful when it reaches the strike price of the options sold, as from there on you will begin incurring losses. It is however exactly the lucky outcome you were hoping for, your stock is higher, and you can buy back those loss making options - then or shortly before. If you didn't sell any options and payed your premium, you don't need to worry at all at this stage. WARNING It should be noted that the Stock Repair Strategy offers no protection for your stock price further falling down. In that case all those options will expire worthless or you can sell back the ones your bought but likely not for much. In order to have the downside protection for your stock, there are other strategies, the simplest one being buying a Put Option at-the-money or slightly lower.

There are a few Exchange Traded Funds (ETFs) that track the price of gold. think of them as stocks that behave like gold, essentially. Two good examples that have options are GLD and IAU. (When you talk about gold, you'll hear a lot about futures. Forget them, for now. They do the same essential thing for your purposes, but introduce more complexity than you need.) The way to profit from a downward move without protection against an upward move is by shorting the stock. Shorting stock is like the opposite of buying it. You make the amount of money the stock goes down by, or lose the amount it goes up by. But, since stocks can go up by an infinite amount, your possible loss is unlimited. If you want to profit on a large downward move without an unlimited loss if you're wrong and it goes up, you need something that makes money as the stock drops, but can only lose so much if it goes up. (If you want to be guaranteed to lose nothing, your best investment option is buying US Treasuries, and you're technically still exposed to the risk that US defaults on its debt, although if you're a US resident, you'll likely have bigger problems than your portfolio in that situation.) Buying a put option has the exact asymmetrical exposure you want. You pay a limited premium to buy it, and at expiration you essentially make the full amount that the stock has declined below the strike price, less what you paid for the option. That last part is important - because you pay a premium for the option, if it's down just a little, you might still lose some or all of what you paid for it, which is what you give up in exchange for it limiting your maximum loss. But wait, you might say. When I buy an option, I can lose all of my money, cant I? Yes, you can. Here's the key to understanding the way options limit risk as compared to the corresponding way to get \"\"normal\"\" exposure through getting long, or in your case, short, the stock: If you use the number of options that represent the number of shares you would have bought, you will have much, much less total money at risk. If you spend the same \"\"bag 'o cash\"\" on options as you would have spent on stock, you will have exposure to way more shares, and have the same amount of money at risk as if you bought the stock, but will be much more likely to lose it. The first way limits the total money at risk for a similar level of exposure; the second way gets you exposure to a much larger amount of the stock for the same money, increasing your risk. So the best answer to your described need is already in the question: Buy a put. I'd probably look at GLD to buy it on, simply because it's generally a little more liquid than IAU. And if you're new to options, consider the following: \"\"Paper trade\"\" first. Either just keep track of fake buys and sells on a spreadsheet, or use one of the many online services where you can track investments - they don't know or care if they're real or not. Check out www.888options.com. They are an excellent learning resource that isn't trying to sell you anything - their only reason to exist is to promote options education. If you do put on a trade, don't forget that the most frustrating pitfall with buying options is this: You can be basically right, and still lose some or all of what you invest. This happens two ways, so think about them both before you trade: If the stock goes in the direction you think, but not enough to make back your premium, you can still lose. So you need to make sure you know how far down the stock has to be to make back your premium. At expiration, it's simple: You need it to be below the strike price by more than what you paid for the option. With options, timing is everything. If the stock goes down a ton, or even to zero - free gold! - but only after your option expires, you were essentially right, but lose all your money. So, while you don't want to buy an option that's longer than you need, since the premium is higher, if you're not sure if an expiration is long enough out, it isn't - you need the next one. EDIT to address update: (I'm not sure \"\"not long enough\"\" was the problem here, but...) If the question is just how to ensure there is a limited, defined amount you can lose (even if you want the possible loss to be much less than you can potentially make, the put strategy described already does that - if the stock you use is at $100, and you buy a put with a 100 strike for $5, you can make up to $95. (This occurs if the stock goes to zero, meaning you could buy it for nothing, and sell it for $100, netting $95 after the $5 you paid). But you can only lose $5. So the put strategy covers you. If the goal is to have no real risk of loss, there's no way to have any real gain above what's sometimes called the \"\"risk-free-rate\"\". For simplicity's sake, think of that as what you'd get from US treasuries, as mentioned above. If the goal is to make money whether the stock (or gold) goes either up or down, that's possible, but note that you still have (a fairly high) risk of loss, which occurs if it fails to move either up or down by enough. That strategy, in its most common form, is called a straddle, which basically means you buy a call and a put with the same strike price. Using the same $100 example, you could buy the 100-strike calls for $5, and the 100-strike puts for $5. Now you've spent $10 total, and you make money if the stock is up or down by more than $10 at expiration (over 110, or under 90). But if it's between 90 and 100, you lose money, as one of your options will be worthless, and the other is worth less than the $10 total you paid for them both.\"", "title": "" }, { "docid": "122188", "text": "Nolube's brain is in his bowels. green-light is pissed as hell.

In this study, we aimed to analyse the associations of blood pressure with 12 different presentations of cardiovascular disease. METHODS We used linked electronic health records from 1997 to 2010 in the CALIBER (CArdiovascular research using LInked Bespoke studies and Electronic health Records) programme to assemble a cohort of 1·25 million patients, 30 years of age or older and initially free from cardiovascular disease, a fifth of whom received blood pressure-lowering treatments. We studied the heterogeneity in the age-specific associations of clinically measured blood pressure with 12 acute and chronic cardiovascular diseases, and estimated the lifetime risks (up to 95 years of age) and cardiovascular disease-free life-years lost adjusted for other risk factors at index ages 30, 60, and 80 years. This study is registered at ClinicalTrials.gov, number NCT01164371. FINDINGS During 5·2 years median follow-up, we recorded 83,098 initial cardiovascular disease presentations. In each age group, the lowest risk for cardiovascular disease was in people with systolic blood pressure of 90-114 mm Hg and diastolic blood pressure of 60-74 mm Hg, with no evidence of a J-shaped increased risk at lower blood pressures. The effect of high blood pressure varied by cardiovascular disease endpoint, from strongly positive to no effect. Associations with high systolic blood pressure were strongest for intracerebral haemorrhage (hazard ratio 1·44 [95% CI 1·32-1·58]), subarachnoid haemorrhage (1·43 [1·25-1·63]), and stable angina (1·41 [1·36-1·46]), and weakest for abdominal aortic aneurysm (1·08 [1·00-1·17]). Compared with diastolic blood pressure, raised systolic blood pressure had a greater effect on angina, myocardial infarction, and peripheral arterial disease, whereas raised diastolic blood pressure had a greater effect on abdominal aortic aneurysm than did raised systolic pressure. Pulse pressure associations were inverse for abdominal aortic aneurysm (HR per 10 mm Hg 0·91 [95% CI 0·86-0·98]) and strongest for peripheral arterial disease (1·23 [1·20-1·27]). People with hypertension (blood pressure ≥140/90 mm Hg or those receiving blood pressure-lowering drugs) had a lifetime risk of overall cardiovascular disease at 30 years of age of 63·3% (95% CI 62·9-63·8) compared with 46·1% (45·5-46·8) for those with normal blood pressure, and developed cardiovascular disease 5·0 years earlier (95% CI 4·8-5·2). Stable and unstable angina accounted for most (43%) of the cardiovascular disease-free years of life lost associated with hypertension from index age 30 years, whereas heart failure and stable angina accounted for the largest proportion (19% each) of years of life lost from index age 80 years. INTERPRETATION The widely held assumptions that blood pressure has strong associations with the occurrence of all cardiovascular diseases across a wide age range, and that diastolic and systolic associations are concordant, are not supported by the findings of this high-resolution study. Despite modern treatments, the lifetime burden of hypertension is substantial. These findings emphasise the need for new blood pressure-lowering strategies, and will help to inform the design of randomised trials to assess them.

OBJECTIVE To ascertain whether the previously reported poor prognosis for individuals with thoracic aortic aneurysms has changed with better medical therapies and improved surgical techniques that can now be applied to aneurysm management. DESIGN Population-based cohort study. SETTING AND PATIENTS All 133 patients with the diagnosis of degenerative thoracic aortic aneurysms among Olmsted County, Minnesota, residents between 1980 and 1994 compared with a previously reported cohort of similar patients between 1951 and 1980. MAIN OUTCOME MEASURES The primary clinical end points were incidence, cumulative rupture risk, rupture risk as a function of aneurysm size, and survival. RESULTS In contrast to abdominal aortic aneurysms, for which men are affected predominately, 51% of thoracic aortic aneurysms were identified in women who were considerably older at recognition than men (mean age, 75.9 vs 62.8 years, respectively; P= .01). The overall incidence rate of 10.4 per 100000 person-years (95% confidence interval [CI], 8.6-12.2) between 1980 and 1994 was more than 3-fold higher than the rate from 1951 to 1980. The cumulative risk of rupture was 20% after 5 years. Seventy-nine percent of ruptures occurred in women (P= .01). The 5-year risk of rupture as a function of aneurysm size at recognition was 0% for aneurysms less than 4 cm in diameter, 16% (95% CI, 4%-28%) for those 4 to 5.9 cm, and 31% (95% CI, 5%-56%) for aneurysms 6 cm or more.

The intriguing complexity of its pathogenesis as well as the importance of its clinical sequelae provide a rationale for this [1]. A large number of diseases with totally different clinical presentations are basically atherosclerosis related, and among these, myocardial infarction, stroke, abdominal aneurysms and lower limb ischemia determine to a large extent the morbidity and mortality in Western style populations. But, despite this broad spectrum of clinical disease, most of the acute manifestations of atherosclerosis share a common pathogenetic feature: rupture of an atherosclerotic plaque [2–4]. Plaque disruptions may vary greatly in extent from tiny fissures or erosions of the plaque surface to deep intimal tears which extend into the soft lipid core of lesions; in all these instances, at least some degree of thrombus formation occurs [5, 6]. The abdominal aorta is the arterial site most prominently involved in the process of plaque formation, and also of plaque complications. In this large diameter vessel the process of plaque disruption and thrombosis is not ended by luminal occlusion, and may lead to extensive surface ulcerations comprising large areas of the aortic wall, as can be observed in many autopsy cases at older age. Apart from the undisputable role of atherosclerosis in abdominal aneurysm formation [7], mural thrombosis leads to a surprisingly low rate of clinically significant complications in these patients, although cholesterol emboli can be regularly found in their kidneys and skin at autopsy. Still, it is presently unclear what impact the various biologically active mediators released from eroded aortic surfaces may have on the human body.

Here, we analyzed echocardiographic aortic root dimension (ARD) in patients with IA to confirm this possibility. METHODS From January 2008 to December 2010, 260 consecutive patients with IA who were admitted to our institution for coil embolization or for acute stroke management and who also underwent echocardiography were enrolled. We hypothesized that patients with large, ruptured, or multiple IAs are more likely to harbor co-prevalent aortopathy as measured by ARD compared to patients with small, isolated, unruptured IAs. Eccentric group was defined as patients aged <55 years with at least one ruptured aneurysm, an aneurysm ≥7 mm in size, or multiple aneurysms; the remainder was classified into a non-eccentric group. Clinical, angiographic, and echocardiographic findings of the two groups were compared. RESULTS ARD was significantly larger in the eccentric group than in the non-eccentric group (P = 0.049), and the difference was confirmed by multivariable analysis (P = 0.02). Subgroup analysis of patients aged <55 years showed similar result for ARD (P = 0.03), whereas hypertension was more associated with the non-eccentric group (P = 0.01).

METHODS We prospectively identified 47 patients who met the diagnostic criteria for definite diastolic heart failure; all the patients had signs and symptoms of heart failure, a normal ejection fraction, and an increased left ventricular end-diastolic pressure. Ten patients who had no evidence of cardiovascular disease served as controls. Left ventricular diastolic function was assessed by means of cardiac catheterization and echocardiography. RESULTS The patients with diastolic heart failure had abnormal left ventricular relaxation and increased left ventricular chamber stiffness. The mean (+/-SD) time constant for the isovolumic-pressure decline (tau) was longer in the group with diastolic heart failure than in the control group (59+/-14 msec vs. 35+/-10 msec, P=0.01).

To reflect more contemporary experience, the starting point of this study was January 1, 1970. EXPOSURE MEASURES - Hypertension (blood pressure of at least 140 mm Hg systolic or 90 mm Hg diastolic or current use of medications for treatment of high blood pressure) and other potential CHF risk factors were assessed at periodic clinic examinations. OUTCOME MEASURE - The development of CHF. RESULTS - A total of 5143 eligible subjects contributed 72422 person-years of observation. During up to 20.1 years of follow-up (mean, 14.1 years), there were 392 new cases of heart failure; in 91% (357/392), hypertension antedated the development of heart failure. Adjusting for age and heart failure risk factors in proportional hazards regression models, the hazard for developing heart failure in hypertensive compared with normotensive subjects was about 2-fold in men and 3-fold in women. Multivariable analyses revealed that hypertension had a high population-attributable risk for CHF, accounting for 39% of cases in men and 59% in women. Among hypertensive subjects, myocardial infarction, diabetes, left ventricular hypertrophy, and valvular heart disease were predictive of increased risk for CHF in both sexes. Survival following the onset of hypertensive CHF was bleak; only 24% of men and 31% of women survived 5 years.

Whether sympathetic overactivity develops early during pregnancy, remaining high throughout gestation, or whether it only occurs at term providing the substrate for hypertensive disorders is unknown. We tested the hypothesis that sympathetic activation occurs early during pregnancy in humans. Eleven healthy women (29 ± 3 (SD) years) without prior hypertensive pregnancies were tested during the mid-luteal phase (PRE) and early pregnancy (EARLY; 6.2 ± 1.2 weeks of gestation). Muscle sympathetic nerve activity (MSNA) and haemodynamics were measured supine, at 30 deg and 60 deg upright tilt for 5 min each. Blood samples were drawn for catecholamines, direct renin, and aldosterone. MSNA was significantly greater during EARLY than PRE (supine: 25 ± 8 vs. 14 ± 8 bursts min(-1), 60 deg tilt: 49 ± 14 vs. 40 ± 10 bursts min(-1); main effect, P < 0.05).

MAIN OUTCOME MEASURES Association between cardiovascular risk variables (levels of low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], and triglycerides; LDL-C/HDL-C ratio; systolic and diastolic blood pressure; body mass index; smoking) measured in childhood and adulthood and common carotid artery IMT measured in adulthood. RESULTS In multivariable models adjusted for age and sex, IMT in adulthood was significantly associated with childhood LDL-C levels (P =.001), systolic blood pressure (P<.001), body mass index (P =.007), and smoking (P =.02), and with adult systolic blood pressure (P<.001), body mass index (P<.001), and smoking (P =.004). The number of risk factors measured in 12- to 18-year-old adolescents, including high levels (ie, extreme age- and sex-specific 80th percentile) of LDL-C, systolic blood pressure, body mass index, and cigarette smoking, were directly related to carotid IMT measured in young adults at ages 33 through 39 years (P<.001 for both men and women), and remained significant after adjustment for contemporaneous risk variables.

Six major classes/groups of antihypertensive medications were categorized by ethnicity, including angiotensin-converting enzyme (ACE) inhibitors, alpha1-blockers, cardioselective beta-blockers (beta1-blockers), calcium channel blockers, thiazide and thiazide-like diuretics, and loop diuretics. RESULTS Using sitting or supine BP, for ethnic groups combined, monodrug therapy with ACE inhibitors showed a weighted average effect of lowering the systolic and diastolic BP by 12.5/9.5 mm Hg; alpha1-blockers by 15.5/11.7 mm Hg; beta1-blockers by 14.8/12.2 mm Hg; calcium channel blockers by 15.3/10.5 mm Hg; thiazide diuretics by 15.3/9.8 mm Hg; and loop diuretics by 15.8/8.2 mm Hg.

MAIN OUTCOME MEASURE Exercise capacity in metabolic equivalents (METs). RESULTS Diastolic dysfunction was strongly and inversely associated with exercise capacity. Compared with normal function, after multivariate adjustment, those with moderate/severe resting diastolic dysfunction (-1.30 METs; 95% confidence interval [CI], -1.52 to -0.99; P < .001) and mild resting diastolic dysfunction (-0.70 METs; 95% CI, -0.88 to -0.46; P < .001) had substantially lower exercise capacity. Variation of left ventricular systolic function within the normal range was not associated with exercise capacity. Left ventricular filling pressures measured by resting E/e' of 15 or greater (-0.41 METs; 95% CI, -0.70 to -0.11; P = .007) or postexercise E/e' of 15 or greater (-0.41 METs; 95% CI, -0.71 to -0.11; P = .007) were similarly associated with a reduction in exercise capacity, each in separate multivariate analyses. Individuals with impaired relaxation (mild dysfunction) or resting E/e' of 15 or greater had a progressive increase in the magnitude of reduction in exercise capacity with advancing age (P < .001 and P = .02, respectively). Other independent correlates of exercise capacity were age (unstandardized beta coefficient, -0.85 METs; 95% CI, -0.92 to -0.77, per 10-year increment; P < .001), female sex (-1.98 METs; 95% CI, -2.15 to -1.84; P < .001), and body mass index greater than 30 (-1.24 METs; 95% CI, -1.41 to -1.10; P < .001). CONCLUSION In this large cross-sectional study of those referred for exercise echocardiography and not limited by ischemia, abnormalities of left ventricular diastolic function were independently associated with exercise capacity.", "title": "Left ventricular function and exercise capacity." }, { "docid": "3825750", "text": "BACKGROUND Diabetic nephropathy is the leading cause of end-stage renal disease in developed countries. We evaluated the renoprotective effects of dual blockade of the renin-angiotensin-aldosterone system by adding treatment with aliskiren, an oral direct renin inhibitor, to treatment with the maximal recommended dose of losartan (100 mg daily) and optimal antihypertensive therapy in patients who had hypertension and type 2 diabetes with nephropathy. METHODS We enrolled 599 patients in this multinational, randomized, double-blind study. After a 3-month, open-label, run-in period during which patients received 100 mg of losartan daily, patients were randomly assigned to receive 6 months of treatment with aliskiren (150 mg daily for 3 months, followed by an increase in dosage to 300 mg daily for another 3 months) or placebo, in addition to losartan. The primary outcome was a reduction in the ratio of albumin to creatinine, as measured in an early-morning urine sample, at 6 months. RESULTS The baseline characteristics of the two groups were similar. Treatment with 300 mg of aliskiren daily, as compared with placebo, reduced the mean urinary albumin-to-creatinine ratio by 20% (95% confidence interval, 9 to 30; P<0.001), with a reduction of 50% or more in 24.7% of the patients who received aliskiren as compared with 12.5% of those who received placebo (P<0.001). A small difference in blood pressure was seen between the treatment groups by the end of the study period (systolic, 2 mm Hg lower [P=0.07] and diastolic, 1 mm Hg lower [P=0.08] in the aliskiren group). The total numbers of adverse and serious adverse events were similar in the groups. CONCLUSIONS Aliskiren may have renoprotective effects that are independent of its blood-pressure-lowering effect in patients with hypertension, type 2 diabetes, and nephropathy who are receiving the recommended renoprotective treatment.

MATERIALS AND METHODS In this HIPAA-compliant, institutional review board approved study, patients with known asymptomatic unruptured intracerebral aneurysms were followed up longitudinally with CT angiographic examinations. Growth was defined as an increase in one or more dimensions above the measurement error, and at least 5% volume by using the ABC/2 method. Associations of epidemiologic factors with aneurysm growth and rupture were analyzed by using logistic regression analysis. Intra- and interobserver agreement coefficients for dimension, volume, and growth were evaluated by using the Pearson correlation coefficient and difference of means with 95% confidence intervals, the agreement statistic, and the McNemar χ(2). RESULTS Patients (n = 165) with aneurysms (n = 258) had a mean follow-up time of 2.24 years from time of diagnosis. Forty-six of 258 (18%) aneurysms in 38 patients grew larger. Spontaneous rupture occurred in four of 228 (1.8%) intradural aneurysms of average size (6.2 mm). Risk of aneurysm rupture per patient-year was 2.4% (95% CI: 0.5%, 7.12%) with growth and 0.2% (95% CI: 0.006%, 1.22%) without growth (P = .034). There was a 12-fold higher risk of rupture for growing aneurysms (P < .002), with high intra- and interobserver correlation coefficients for size, volume, and growth. Tobacco smoking (3.806, one degree of freedom; P < .015,) and initial size (5.895, two degrees of freedom; P < .051) were independent covariates, predicting 78.4% of growing aneurysms. CONCLUSION These results support imaging follow-up of all patients with aneurysms, including those whose aneurysms are smaller than the current 7-mm treatment threshold.

Tai chi chih (TCC) is a mind-body exercise associated with reductions in chronic disease risk factors, but has not been examined with older cancer survivors. In a feasibility randomized controlled trial of TCC, we examined secondary outcomes of blood pressure, salivary cortisol, and inflammatory cytokines (interleukin (IL)-6, IL-12, tumor necrosis factor-α, IL-10, IL-4) due to their implications in chronic diseases. Sixty-three senior female cancer survivors (M age = 67 years, SD = 7.15) with physical functioning limitations (SF-12 physical functioning ≤80 or role-physical ≤72) were randomized to 12-weeks (60-min, three times a week) of TCC or Health Education control (HEC) classes.

Whether it or other genes activated in the athlete's heart might have an impact on cardiac function and survival in a setting of heart failure is unknown. To examine whether progressive exercise training and PI3K(p110alpha) activity affect survival and/or cardiac function in two models of heart disease, we subjected a transgenic mouse model of dilated cardiomyopathy (DCM) to swim training, genetically crossed cardiac-specific transgenic mice with increased or decreased PI3K(p110alpha) activity to the DCM model, and subjected PI3K(p110alpha) transgenics to acute pressure overload (ascending aortic constriction). Life-span, cardiac function, and molecular markers of pathological hypertrophy were examined. Exercise training and increased cardiac PI3K(p110alpha) activity prolonged survival in the DCM model by 15-20%. In contrast, reduced PI3K(p110alpha) activity drastically shortened lifespan by approximately 50%. Increased PI3K(p110alpha) activity had a favorable effect on cardiac function and fibrosis in the pressure-overload model and attenuated pathological growth. PI3K(p110alpha) signaling negatively regulated G protein-coupled receptor stimulated extracellular responsive kinase and Akt (via PI3K, p110gamma) activation in isolated cardiomyocytes.

Furthermore, in the context of mice on a Western diet, genetically induced deficiency of mast cells, or their pharmacological stabilization, reduces body weight gain and levels of inflammatory cytokines, chemokines and proteases in serum and WAT, in concert with improved glucose homeostasis and energy expenditure. Mechanistic studies reveal that mast cells contribute to WAT and muscle angiogenesis and associated cell apoptosis and cathepsin activity. Adoptive transfer experiments of cytokine-deficient mast cells show that these cells, by producing interleukin-6 (IL-6) and interferon-gamma (IFN-gamma), contribute to mouse adipose tissue cysteine protease cathepsin expression, apoptosis and angiogenesis, thereby promoting diet-induced obesity and glucose intolerance.

We undertook systematic reviews of studies from low-income and middle-income countries for these outcomes and for indicators related to blood lipids, cardiovascular disease, lung and immune function, cancers, osteoporosis, and mental illness. Undernutrition was strongly associated, both in the review of published work and in new analyses, with shorter adult height, less schooling, reduced economic productivity, and--for women--lower offspring birthweight. Associations with adult disease indicators were not so clear-cut. Increased size at birth and in childhood were positively associated with adult body-mass index and to a lesser extent with blood pressure values, but not with blood glucose concentrations. In our new analyses and in published work, lower birthweight and undernutrition in childhood were risk factors for high glucose concentrations, blood pressure, and harmful lipid profiles once adult body-mass index and height were adjusted for, suggesting that rapid postnatal weight gain--especially after infancy--is linked to these conditions. The review of published works indicates that there is insufficient information about long-term changes in immune function, blood lipids, or osteoporosis indicators. Birthweight is positively associated with lung function and with the incidence of some cancers, and undernutrition could be associated with mental illness. We noted that height-for-age at 2 years was the best predictor of human capital and that undernutrition is associated with lower human capital. We conclude that damage suffered in early life leads to permanent impairment, and might also affect future generations. Its prevention will probably bring about important health, educational, and economic benefits.

It massively advanced the productive output of the industry, and required far less workforce. This was THE central cause of the precipitous drop to the coal industry workforce before the 1990s. Thereafter, a confluence of prices, competition, attacks on the working class/unions, of new energy sources, etc and other factors were the mixture which reduced the workforce. **Two**, strip mining (and lignite-type coal; lower workforce necessary) in the Western coal region also played a role rather than the demands of underground mining (mostly bituminous, but also anthracite-type coal, concentrated in the East; higher workforce necessary). Key to remember that this move from eastern to western coal production, while reducing the workforce, was a **major drive** by the **coal bosses in the 90s through the 2000s.** A major aspect was that this was a campaign by the owners/bosses seeking to side-step the UMWA and unions/labor costs/health/dental. The eastern mines were dominantly Union, but out west, the union movement in the coal industry unfortunately never had broad modern success. Moments of greatness occurred in the western UMWA organizing battles (some great Navjao nation unionists, some good locals in Colorado too, a few valiant UT battles – one in particular which was lead by miners who were originally from Mexico), but no where near like east of the Mississippi. **Three**. Anyone who worked or even lived near the industry (lived in Appalachia or Western Coal), could have told the young Atlantic author, or the Stanford Institute fellow just about all of this.

Supply is constrained as there aren't much in the way of new bitcoins coming into existence, and demand is high right now as a result of various events. For example, this Reuters article goes into some detail as to some current influences. Mostly, crypto-hedge funds are buying a lot of bitcoins as a speculative move (i.e., believing the price will continue to rise). The evidence suggests that few of the users are buying bitcoin to use it as a means of exchange, but are speculating to increase their capital. Many describe the bubble as similar to the Tulip craze in seventeenth century Holland; from the same Reuters article: “It’s got all the shapings of your tulip bubble chart (but) that tells you nothing about where that price line could go depending on the number of people who wish to own it,” Standard Life’s head of investment strategy, Andrew Milligan, said on Wednesday. “Who is to say it doesn’t reach $100,000?” You can see in the volume chart from blockchain.info that the trading volume for bitcoins has really increased - and if you look at the market price, you see a very similar movement. However, if you look at the number of transactions per day, that number is basically constant - meaning the actual uses of bitcoins by people just buying or selling goods or services isn't really changing much, but the dollar amount is. That's indicative of a speculation-caused bubble. Below is a graph I made from the data from blockchain.info above that overlays price with trading volume; you can see clearly the increase in volume and increase in price are nearly simultaneous. Bitcoin itself has some actual utility, mostly for black market sellers and similar people participating in activities that are less than legal (not necesesarily ethically bad, for example people in nations with oppressive regimes that limit contact with the outside world or try to restrict foreign currency purchases). It's unlikely that the degree of adoption so far however has driven it to this level, and the fact that bitcoin can be broken up into very small chunks means that the big boom in price of individual bitcoins causes the demand-side pressure from the actual use of bitcoins to be alleviated (as there is now 1/10th the demand for bitcoins from people who use them for non-speculative reasons).", "title": "" }, { "docid": "19367", "text": "With your experience, I think you'd agree that trading over a standardized, regulated exchange is much more practical with the amount of capital you plan to trade with.

Exposure results principally from consumption by pregnant women of seafood contaminated by mercury from anthropogenic (70%) and natural (30%) sources. Throughout the 1990s, the U.S. Environmental Protection Agency (EPA) made steady progress in reducing mercury emissions from anthropogenic sources, especially from power plants, which account for 41% of anthropogenic emissions. However, the U.S. EPA recently proposed to slow this progress, citing high costs of pollution abatement. To put into perspective the costs of controlling emissions from American power plants, we have estimated the economic costs of methyl mercury toxicity attributable to mercury from these plants. We used an environmentally attributable fraction model and limited our analysis to the neurodevelopmental impacts—specifically loss of intelligence. Using national blood mercury prevalence data from the Centers for Disease Control and Prevention, we found that between 316,588 and 637,233 children each year have cord blood mercury levels > 5.8 μg/L, a level associated with loss of IQ. The resulting loss of intelligence causes diminished economic productivity that persists over the entire lifetime of these children. This lost productivity is the major cost of methyl mercury toxicity, and it amounts to $8.7 billion annually (range, $2.2–43.8 billion; all costs are in 2000 US$). Of this total, $1.3 billion (range, $0.1–6.5 billion) each year is attributable to mercury emissions from American power plants.

Few studies have examined whether chronic exposure at lower levels could adversely affect children’s cognitive development. Objective: We examined associations between prenatal and postnatal exposure to OP pesticides and cognitive abilities in school-age children. Methods: We conducted a birth cohort study (Center for the Health Assessment of Mothers and Children of Salinas study) among predominantly Latino farmworker families from an agricultural community in California. We assessed exposure to OP pesticides by measuring dialkyl phosphate (DAP) metabolites in urine collected during pregnancy and from children at 6 months and 1, 2, 3.5, and 5 years of age. We administered the Wechsler Intelligence Scale for Children, 4th edition, to 329 children 7 years of age. Analyses were adjusted for maternal education and intelligence, Home Observation for Measurement of the Environment score, and language of cognitive assessment. Results: Urinary DAP concentrations measured during the first and second half of pregnancy had similar relations to cognitive scores, so we used the average of concentrations measured during pregnancy in further analyses. Averaged maternal DAP concentrations were associated with poorer scores for Working Memory, Processing Speed, Verbal Comprehension, Perceptual Reasoning, and Full-Scale intelligence quotient (IQ). Children in the highest quintile of maternal DAP concentrations had an average deficit of 7.0 IQ points compared with those in the lowest quintile. However, children’s urinary DAP concentrations were not consistently associated with cognitive scores.

METHODS: We followed 84,941 female nurses from 1980 to 1996; these women were free of diagnosed cardiovascular disease, diabetes, and cancer at base line. Information about their diet and lifestyle was updated periodically. A low-risk group was defined according to a combination of five variables: a bodymass index (the weight in kilograms divided by the square of the height in meters) of less than 25; a diet high in cereal fiber and polyunsaturated fat and low in trans fat and glycemic load (which reflects the effect of diet on the blood glucose level); engagement in moderate-to-vigorous physical activity for at least half an hour per day; no current smoking; and the consumption of an average of at least half a drink of an alcoholic beverage per day. RESULTS: During 16 years of follow-up, we documented 3300 new cases of type 2 diabetes. Overweight or obesity was the single most important predictor of diabetes. Lack of exercise, a poor diet, current smoking, and abstinence from alcohol use were all associated with a significantly increased risk of diabetes, even after adjustment for the body-mass index.

A total of 867 incident GDM cases were reported. Pooled logistic regression was used to estimate the relative risk (RR) of GDM by quintiles of iron intake controlling for dietary and nondietary risk factors. RESULTS Dietary heme iron intake was positively and significantly associated with GDM risk.

In COS-1 cells transiently transfected with an oestrogen-responsive reporter gene, PhIP (10(-10)-10(-6) M) mediated transcription through oestrogen receptor (ER) alpha, but not ER-beta, and inhibition by the pure ER antagonist ICI 182 780 demonstrated a requirement for a functional ER.

Diet vs. Exercise: What’s More Important?
[ { "docid": "MED-4286", "text": "Nuts are rich sources of multiple nutrients and phytochemicals associated with health benefits, including reduced cardiovascular disease risk. This has prompted recommendations to increase their consumption. However, they are also high in fat and are energy dense. The associations between these properties, positive energy balance and body weight raise questions about such recommendations. Numerous epidemiological and clinical studies show that nuts are not associated with weight gain. Mechanistic studies indicate this is largely attributable to the high satiety and low metabolizable energy (poor bioaccessibility leading to inefficient energy absorption) properties of nuts. Compensatory dietary responses account for 55-75% of the energy provided by nuts. Limited data suggest that routine nut consumption is associated with elevated resting energy expenditure and the thermogenic effect of feeding, resulting in dissipation of another portion of the energy they provide. Additionally, trials contrasting weight loss through regimens that include or exclude nuts indicate improved compliance and greater weight loss when nuts are permitted. Nuts may be included in the diet, in moderation, to enhance palatability, nutrient quality, and chronic disease risk reduction without compromising weight loss or maintenance.", "title": "Nuts and healthy body weight maintenance mechanisms." }, { "docid": "MED-5327", "text": "OBJECTIVE: To investigate the associations between dietary patterns and mental health in early adolescence. METHOD: The Western Australian Pregnancy Cohort (Raine) Study is a prospective study of 2900 pregnancies recruited from 1989-1992.

Two dietary patterns (Western and Healthy) were identified using factor analysis and food group intakes estimated by a 212-item food frequency questionnaire. Relationships between dietary patterns, food group intakes and behaviour were examined using general linear modelling following adjustment for potential confounding factors at age 14: total energy intake, body mass index, physical activity, screen use, family structure, income and functioning, gender and maternal education at pregnancy. RESULTS: Higher total (b=2.20, 95% CI=1.06, 3.35), internalizing (withdrawn/depressed) (b=1.25, 95% CI=0.15, 2.35) and externalizing (delinquent/aggressive) (b=2.60, 95% CI=1.51, 3.68) CBCL scores were significantly associated with the Western dietary pattern, with increased intakes of takeaway foods, confectionary and red meat.

Associations between energy from meat (kcal/d) and annual weight change (g/y) were assessed with the use of linear mixed models, controlled for age, sex, total energy intake, physical activity, dietary patterns, and other potential confounders. RESULTS: Total meat consumption was positively associated with weight gain in men and women, in normal-weight and overweight subjects, and in smokers and nonsmokers. With adjustment for estimated energy intake, an increase in meat intake of 250 g/d (eg, one steak at approximately 450 kcal) would lead to a 2-kg higher weight gain after 5 y (95% CI: 1.5, 2.7 kg).

Therefore, we evaluated the effects of comprehensive lifestyle changes on prostate specific antigen (PSA), treatment trends and serum stimulated LNCaP cell growth in men with early, biopsy proven prostate cancer after 1 year. MATERIALS AND METHODS: Patient recruitment was limited to men who had chosen not to undergo any conventional treatment, which provided an unusual opportunity to have a nonintervention randomized control group to avoid the confounding effects of interventions such as radiation, surgery or androgen deprivation therapy. A total of 93 volunteers with serum PSA 4 to 10 ng/ml and cancer Gleason scores less than 7 were randomly assigned to an experimental group that was asked to make comprehensive lifestyle changes or to a usual care control group. RESULTS: None of the experimental group patients but 6 control patients underwent conventional treatment due to an increase in PSA and/or progression of disease on magnetic resonance imaging. PSA decreased 4% in the experimental group but increased 6% in the control group (p = 0.016). The growth of LNCaP prostate cancer cells (American Type Culture Collection, Manassas, Virginia) was inhibited almost 8 times more by serum from the experimental than from the control group (70% vs 9%, p <0.001). Changes in serum PSA and also in LNCaP cell growth were significantly associated with the degree of change in diet and lifestyle.

High-fat diet associated triglyceride-rich lipoproteins have also been suggested to be atherogenic. To assess the direct effect of postprandial triglyceride-rich lipoproteins on endothelial function, an early factor in atherogenesis--10 healthy, normocholesterolemic volunteers--were studied before and for 6 hours after single isocaloric high- and low-fat meals (900 calorie; 50 and 0 g fat, respectively). Endothelial function, in the form of flow-mediated vasoactivity, was assessed in the brachial artery using 7.5-MHz ultrasound as percent arterial diameter change 1 minute after 5 minutes of upper-arm arterial occlusion. Serum lipoproteins and glucose were determined before eating and 2 and 4 hours postprandially. Serum triglycerides increased from 94 +/- 55 mg/dl preprandially to 147 +/- 80 mg/dl 2 hours after the high-fat meal (p = 0.05). Flow-dependent vasoactivity decreased from 21 +/- 5% preprandially to 11 +/- 4%, 11 +/- 6%, and 10 +/- 3% at 2, 3, and 4 hours after the high-fat meal, respectively (all p <0.05 compared with low-fat meal data). No changes in lipoproteins or flow-mediated vasoactivity were observed after the low-fat meal. Fasting low-density lipoprotein cholesterol correlated inversely (r = -0.47, p = 0.04) with preprandial flow-mediated vasoactivity, but triglyceride level did not. Mean change in postprandial flow-mediated vasoactivity at 2, 3, and 4 hours correlated with change in 2-hour serum triglycerides (r = -0.51, p = 0.02). These results demonstrate that a single high-fat meal transiently impairs endothelial function.

Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) Scale. Dietary patterns were derived by using principal component analysis of the consumption of 52 food and beverage items, which was assessed by a validated brief diet history questionnaire. Logistic regression analysis was used to estimate odds ratios of depressive symptoms (CES-D >or=16) with adjustment for potential confounding variables. RESULTS: We identified three dietary patterns. A healthy Japanese dietary pattern characterized by high intakes of vegetables, fruit, mushrooms and soy products was associated with fewer depressive symptoms.

Criteria were established for vegan, lacto-ovo vegetarian, partial vegetarian and omnivorous dietary patterns. Setting Clinics were conducted at churches across the USA and Canada.

Findings for lacto-ovo vegetarians (β = −9·1, P<0·001 and β = −5·8, P<0·001) were similar. The vegetarians (mainly the vegans) were also less likely to be using antihypertensive medications. Defining hypertension as systolic BP > 139 mmHg or diastolic BP > 89 mmHg or use of antihypertensive medications, the odds ratio of hypertension compared with omnivores was 0·37 (95 % CI 0·19, 0·74), 0·57 (95 % CI 0·36, 0·92) and 0·92 (95 % CI 0·50, 1·70), respectively, for vegans, lacto-ovo vegetarians and partial vegetarians.

The burden of non-communicable diseases (NCDs) is increasing rapidly in the developing world, very much as a result of changes in lifestyles. In addition to changes in tobacco use and physical activity, major changes are taking place in diets, contributing greatly to the growing epidemic of NCD. Thus, a huge global public health challenge is how to influence the trends in diet and nutrition for effective global NCD prevention. The health transition took place rapidly in Finland after World War II and mortality from cardiovascular disease (CVD) was exceptionally high. The North Karelia Project was launched in 1972 as a community-based, and later as a national, programme to influence diet and other lifestyles that are crucial in the prevention of CVD. The intervention had a strong theory base and it employed comprehensive strategies. Broad community organisation and the strong participation of people were the key elements. Evaluation has shown how the diet (particularly fat consumption) has changed and how these changes have led to a major reduction in population serum cholesterol and blood pressure levels. It has also shown how ischaemic heart disease mortality in a working-age population has declined by 73% in North Karelia and by 65% in the whole country from 1971 to 1995. Although Finland is an industrialised country, North Karelia was rural, of rather low socio-economic level and with many social problems in the 1970s and 1980s. The project was based on low-cost intervention activities, where people's participation and community organisations played a key role. Comprehensive interventions in the community were eventually supported by national activities--from expert guidelines and media activities to industry collaboration and policy. Similar principles for nutrition intervention programmes could be used in developing countries, obviously tailored to the local conditions.

Methods This was an anonymous questionnaire survey carried out in a single primary care group. A random sample of patients from the practice list stratified by age and gender were surveyed to determine what benefit they required before deciding to receive first and subsequent drugs to treat hypertension. They were asked to indicate the largest number needing treatment for 5 years (NNT5) to prevent myocardial infarction in 1 (smallest benefit) that would persuade them of the need for treatment. Demographic information which might explain variability in enthusiasm for treatment was also collected. Results Participants required far higher benefit to consider drug treatment than expected with a mean NNT5 for the first treatment of 15.0 (95% CI 12.3, 17.8). Marginal benefit demanded for the addition of second and third treatments was at least as great with an NNT5 of 13.2 (95% CI 10.8, 15.7) and NNT5 of 11.0 (95% CI 8.6, 13.4). Additional factors influencing willingness to take treatment were gender with a difference in NNT5 between men and women of 7.1 (95% CI 1.7, 12.5), difficulty in making the decision (very easy vs very difficult) of 14.9 (95% CI 6.0, 23.8), and years in full time education 2.0 (95% CI 0.9, 3.0) for each additional year of education. Any slope of NNT5 with increasing number of tablets disappeared when gender, years in education, and difficulty in reaching a decision were taken into account simultaneously. Conclusions People may have greater expectation of benefit from antihypertensive drug treatment than it provides.

On analytical point of view the identification, quantification and characterization of NPs in food matrices and in cosmetic or personal care products pose significant challenges, because NPs are usually present at low concentration levels and the matrices, in which they are dispersed, are complexes and often incompatible with analytical instruments that would be required for their detection and characterization.

We summarize the benefits of regular exercise on longevity, present the current knowledge regarding potential mechanisms, and outline the main recommendations. Exercise can partially reverse the effects of the aging process on physiological functions and preserve functional reserve in the elderly.

Training programs should include exercises aimed at improving cardiorespiratory fitness and muscle function, as well as flexibility and balance. Though the benefits of physical activity appear to be directly linked to the notion of training volume and intensity, further research is required in the elderly, in order to develop more precise recommendations, bearing in mind that the main aim is to foster long-term adherence to physical activity in this growing population.

Intra-abdominal fat is associated with insulin resistance, possibly mediated by greater lipolytic activity, lower adiponectin levels, resistance to leptin, and increased inflammatory cytokines, although the latter contribution is less clear. Liver lipid is also closely associated with, and likely to be an important contributor to, insulin resistance, but it may also be in part the consequence of the lipogenic pathway of insulin action being up-regulated by hyperinsulinemia and unimpaired signaling. Again, intramyocellular triglyceride is associated with muscle insulin resistance, but anomalies include higher intramyocellular triglyceride in insulin-sensitive athletes and women (vs men). Such issues could be explained if the \"culprits\" were active lipid moieties such as diacylglycerol and ceramide species, dependent more on lipid metabolism and partitioning than triglyceride amount. Subcutaneous fat, especially gluteofemoral, appears metabolically protective, illustrated by insulin resistance and dyslipidemia in patients with lipodystrophy. However, some studies suggest that deep sc abdominal fat may have adverse properties. Pericardial and perivascular fat relate to atheromatous disease, but not clearly to insulin resistance. There has been recent interest in recognizable brown adipose tissue in adult humans and its possible augmentation by a hormone, irisin, from exercising muscle.

Even though inhaling mint aroma in athletes has been investigated, there were no significant effects on the exercise performance. Methods Twelve healthy male students every day consumed one 500 ml bottle of mineral water, containing 0.05 ml peppermint essential oil for ten days. Blood pressure, heart rate, and spirometry parameters including forced vital capacity (FVC), peak expiratory flow rate (PEF), and peak inspiratory flow (PIF) were determined one day before, and after the supplementation period. Participants underwent a treadmill-based exercise test with metabolic gas analysis and ventilation measurement using the Bruce protocol. Results The FVC (4.57 ± 0.90 vs. 4.79 ± 0.84; p < 0.001), PEF (8.50 ± 0.94 vs. 8.87 ± 0.92; p < 0.01), and PIF (5.71 ± 1.16 vs. 6.58 ±1.08; p < 0.005) significantly changed after ten days of supplementation.

However, great variation exists in what is considered normal healthy gut and immune function. Thus, whilst it is possible to measure many aspects of digestion and immunity, it is more difficult to interpret the benefits to individuals of variation within what is considered to be a normal range. Nevertheless, it is important to set standards for optimal function for use both by the consumer, industry and those concerned with the public health. The digestive tract is most frequently the object of functional and health claims and a large market already exists for gut-functional foods worldwide. AIM: To define normal function of the gut and immune system and describe available methods of measuring it. RESULTS: We have defined normal bowel habit and transit time, identified their role as risk factors for disease and how they may be measured. Similarly, we have tried to define what is a healthy gut flora in terms of the dominant genera and their metabolism and listed the many, varied and novel methods for determining these parameters. It has proved less easy to provide boundaries for what constitutes optimal or improved gastric emptying, gut motility, nutrient and water absorption and the function of organs such as the liver, gallbladder and pancreas. The many tests of these functions are described. We have discussed gastrointestinal well being. Sensations arising from the gut can be both pleasant and unpleasant. However, the characteristics of well being are ill defined and merge imperceptibly from acceptable to unacceptable, a state that is subjective. Nevertheless, we feel this is an important area for future work and method development. The immune system is even more difficult to make quantitative judgements about. When it is defective, then clinical problems ensure, but this is an uncommon state. The innate and adaptive immune systems work synergistically together and comprise many cellular and humoral factors. The adaptive system is extremely sophisticated and between the two arms of immunity there is great redundancy, which provides robust defences. New aspects of immune function are discovered regularly. It is not clear whether immune function can be \"improved\". Measuring aspects of immune function is possible but there is no one test that will define either the status or functional capacity of the immune system. Human studies are often limited by the ability to sample only blood or secretions such as saliva but it should be remembered that only 2% of lymphocytes circulate at any given time, which limits interpretation of data. We recommend assessing the functional capacity of the immune system by: measuring specific cell functions ex vivo. measuring in vivo responses to challenge, e. g. change in antibody in blood or response to antigens. determining the incidence and severity of infection in target populations during naturally occurring episodes or in response to attenuated pathogens.", "title": "PASSCLAIM--gut health and immunity." }, { "docid": "MED-4452", "text": "Background: Evidence for the role of diet and physical activity in cancer incidence is well documented, but owing to increased cancer survivorship, an understanding of these lifestyle factors after a cancer diagnosis is of crucial importance.

Evidence from observational studies suggests that a low-fat, high-fibre diet might be protective against cancer recurrence and progression. However, there is a paucity of RCTs substantiating this. There is more support for physical activity, with a dose response for better outcomes. When synthesized with findings from the World Cancer Research Fund review of RCTs investigating the effect of diet and physical activity interventions on cancer survival, evidence suggests that the mechanism of benefit from diet and physical activity pertains to body weight, with excess body weight being a risk factor, which is modifiable through lifestyle.

Methodology/Principal Findings MBF was measured with 15O-labelled H2O and Positron Emission Tomography (PET) at rest and after supine bicycle exercise in controls (n = 15, mean age 58±13 years) and in CAD patients (n = 15, mean age 61±9 years).

Increased production of fermentation-derived short-chain fatty acids (SCFAs) is one of the factors that could exert these positive effects. This review examines the effects of SCFAs on immune cells and discusses the relevance of their effects on systemic inflammation, as frequently seen in obesity. RECENT FINDINGS: SCFAs have been shown to reduce chemotaxis and cell adhesion; this effect is dependent on type and concentration of SCFA. In spite of conflicting results, especially butyrate seems to have an anti-inflammatory effect, mediated by signaling pathways like nuclear factor-κB and inhibition of histone deacetylase. The discrepancies in the results could be explained by differences in cell types used and their proliferative and differentiation status. SUMMARY: SCFAs show anti-inflammatory effects and seem to have the potency to prevent infiltration of immune cells from the bloodstream in, for example, the adipose tissue. In addition, their ability to inhibit the proliferation and activation of T cells and to prevent adhesion of antigen-presenting cells could be important as it recently has been shown that obesity-associated inflammation might be antigen-dependent.

PCB 126>59.1 pg/g lipid adjusted had an odds ratio of 2.45 (95% CI 1.48-4.04) compared to PCB 126<or=26.1 pg/g lipid adjusted. PCB 118>27.5 ng/g lipid adjusted had an odds ratio of 2.30 (95% CI 1.29-4.08) compared to PCB 118<or=12.5 ng/g lipid adjusted. Moreover, participants with one or more elevated PCBs had an odds ratio of 1.84 (95% CI 1.25-2.70) compared to no PCBs elevated in an adjusted logistic regression. The prevalence of one or more elevated PCBs was 22.76% or 32 million of 142 million persons >or=20 years old in the non-institutionalized US population.

Intakes of dietary fiber in different populations internationally vary widely from less than 20 g to more than 80 g per day. The types of foods contributing fiber also vary; in some countries cereals contribute the most fiber, in others leafy or root vegetables predominate. Vegetables have the highest fiber content per Kcal, and in most populations with fiber intakes over 50 g, vegetables contribute over 50% of total fiber intake. In rural Uganda, where the fiber hypothesis was first developed by Burkitt and Trowell, vegetables contribute over 90% of fiber intake. An experimental diet, the \"Simian\" diet, has been developed to mimic as closely as possible using human foods, the diet consumed by our simian ancestors the great apes. It is also similar to the Ugandan diet in containing large amounts of vegetables and 50 g fiber/1000 Kcal. Though nutritionally adequate, this diet is very bulky and not a suitable model for general recommendations. Dietary guidelines are that fat intake should be < 30% of energy, with a fiber intake of 20-35 g/d. These recommendations are inconsistent with a high fiber diet because, for people consuming more than about 2400 Kcal, low fiber choices for fruits and grains must be selected to keep dietary fiber intake within the range of 20-35 g. In a 30% fat, 1800 Kcal omnivorous diet, selection of wholemeal bread and whole fruit, results in a fiber intake over 35 g/d, and for and 1800 Kcal vegetarian diet, with substitution of modest amounts of peanut butter and beans for meats, dietary fiber intake goes up to 45 g/d.

In this narrative review, we pose the opposite question: can ingested food affect sleep? The purpose of this review is to discuss the evidence linking diet and sleep and to determine whether what we eat and what kind of nutrients we obtain from the food consumed before bedtime matter. In addition, scientific evidence behind traditional sleep-promoting foods such as milk and some herbal products is briefly described. These are reviewed using data from clinical trials, mostly in healthy subjects. In addition, we discuss the possible mechanisms behind these observations. Lastly, we summarize our findings that emerging evidence confirms a link between diet and sleep. Overall, foods impacting the availability of tryptophan, as well as the synthesis of serotonin and melatonin, may be the most helpful in promoting sleep.

The role of fruit phenolic compounds to protect health and lower disease risk through their actions in mitigating fed-state metabolic and oxidative stressors is of interest and the topic of the present paper. Two main questions are posed: first, what is the role of plant foods, specifically fruits rich in complex and simple phenolic compounds in postprandial metabolic management; and second, does the evidence support consuming these fruits with meals as a practical strategy to preserve health and lower risk for disease? This review provides an overview of the postprandial literature, specifically on the effect of fruits and their inherent phenolic compounds in human subjects on postprandial lipaemia, glycaemia/insulinaemia and associated events, such as oxidative stress and inflammation. Among the identified well-controlled human trials using a postprandial paradigm, >50 % of the trials used wine or wine components and the remaining used various berries.

We aimed to quantify the potential combined impact of four health behaviours on mortality in men and women living in the general community. Methods and Findings We examined the prospective relationship between lifestyle and mortality in a prospective population study of 20,244 men and women aged 45–79 y with no known cardiovascular disease or cancer at baseline survey in 1993–1997, living in the general community in the United Kingdom, and followed up to 2006. Participants scored one point for each health behaviour: current non-smoking, not physically inactive, moderate alcohol intake (1–14 units a week) and plasma vitamin C >50 mmol/l indicating fruit and vegetable intake of at least five servings a day, for a total score ranging from zero to four. After an average 11 y follow-up, the age-, sex-, body mass–, and social class–adjusted relative risks (95% confidence intervals) for all-cause mortality(1,987 deaths) for men and women who had three, two, one, and zero compared to four health behaviours were respectively, 1.39 (1.21–1.60), 1.95 (1.70–-2.25), 2.52 (2.13–3.00), and 4.04 (2.95–5.54) p < 0.001 trend. The relationships were consistent in subgroups stratified by sex, age, body mass index, and social class, and after excluding deaths within 2 y. The trends were strongest for cardiovascular causes. The mortality risk for those with four compared to zero health behaviours was equivalent to being 14 y younger in chronological age. Conclusions Four health behaviours combined predict a 4-fold difference in total mortality in men and women, with an estimated impact equivalent to 14 y in chronological age. Editors' Summary Background. Every day, or so it seems, new research shows that some aspect of lifestyle—physical activity, diet, alcohol consumption, and so on—affects health and longevity. For the person in the street, all this information is confusing. What is a healthy diet, for example? Although there are some common themes such as the benefit of eating plenty of fruit and vegetables, the details often differ between studies. And exactly how much physical activity is needed to improve health? Is a gentle daily walk sufficient or simply a stepping stone to doing enough exercise to make a real difference? The situation with alcohol consumption is equally confusing. Small amounts of alcohol apparently improve health but large amounts are harmful. As a result, it can be hard for public-health officials to find effective ways to encourage the behavioral changes that the scientific evidence suggests might influence the health of populations. Why Was This Study Done? There is another factor that is hindering official attempts to provide healthy lifestyle advice to the public. Although there is overwhelming evidence that individual behavioral factors influence health, there is very little information about their combined impact. If the combination of several small differences in lifestyle could be shown to have a marked effect on the health of populations, it might be easier to persuade people to make behavioral changes to improve their health, particularly if those changes were simple and relatively easy to achieve. In this study, which forms part of the European Prospective Investigation into Cancer and Nutrition (EPIC), the researchers have examined the relationship between lifestyle and the risk of dying using a health behavior score based on four simply defined behaviors—smoking, physical activity, alcohol drinking, and fruit and vegetable intake. What Did the Researchers Do and Find? Between 1993 and 1997, about 20,000 men and women aged 45–79 living in Norfolk UK, none of whom had cancer or cardiovascular disease (heart or circulation problems), completed a health and lifestyle questionnaire, had a health examination, and had their blood vitamin C level measured as part of the EPIC-Norfolk study. A health behavior score of between 0 and 4 was calculated for each participant by giving one point for each of the following healthy behaviors: current non-smoking, not physically inactive (physical inactivity was defined as having a sedentary job and doing no recreational exercise), moderate alcohol intake (1–14 units a week; a unit of alcohol is half a pint of beer, a glass of wine, or a shot of spirit), and a blood vitamin C level consistent with a fruit and vegetable intake of at least five servings a day. Deaths among the participants were then recorded until 2006. After allowing for other factors that might have affected their likelihood of dying (for example, age), people with a health behavior score of 0 were four times as likely to have died (in particular, from cardiovascular disease) than those with a score of 4. People with a score of 2 were twice as likely to have died. What Do These Findings Mean? These findings indicate that the combination of four simply defined health behaviors predicts a 4-fold difference in the risk of dying over an average period of 11 years for middle-aged and older people. They also show that the risk of death (particularly from cardiovascular disease) decreases as the number of positive health behaviors increase. Finally, they can be used to calculate that a person with a health score of 0 has the same risk of dying as a person with a health score of 4 who is 14 years older. These findings need to be confirmed in other populations and extended to an analysis of how these combined health behaviors affect the quality of life as well as the risk of death. Nevertheless, they strongly suggest that modest and achievable lifestyle changes could have a marked effect on the health of populations. Armed with this information, public-health officials should now be in a better position to encourage behavior changes likely to improve the health of middle-aged and older people.

Soy genistein has important anti-inflammatory and other biological effects that might be beneficial in asthma. A positive association was previously reported between soy genistein intake and lung function but not with asthma exacerbations. Aims To conduct a post-hoc analysis of patients with inadequately controlled asthma enrolled in a prospective multicentre clinical trial to replicate this association. Methods A total of 300 study participants were included in the analysis. Dietary soy genistein intake was measured using the Block Soy Foods Screener. The level of soy genistein intake (little or no intake, moderate intake, or high intake) was compared with baseline lung function (pre-bronchodilator forced expiratory volume in 1 second (FEV1)) and asthma control (proportion of participants with an episode of poor asthma control (EPAC) and annualised rates of EPACs over a 6-month follow-up period. Results Participants with little or no genistein intake had a lower baseline FEV1 than those with a moderate or high intake (2.26L vs. 2.53L and 2.47L, respectively; p=0.01). EPACs were more common among those with no genistein intake than in those with a moderate or high intake (54% vs. 35% vs. 40%, respectively; p<0.001).

Participants A total of 96 469 Seventh-day Adventist men and women recruited between 2002 and 2007, from which an analytic sample of 73 308 participants remained after exclusions. Exposures Diet was assessed at baseline by a quantitative food frequency questionnaire and categorized into 5 dietary patterns: nonvegetarian, semi-vegetarian, pesco-vegetarian, lacto-ovo–vegetarian, and vegan. Main Outcome and Measure The relationship between vegetarian dietary patterns and all-cause and cause-specific mortality; deaths through 2009 were identified from the National Death Index. Results There were 2570 deaths among 73 308 participants during a mean follow-up time of 5.79 years. The mortality rate was 6.05 (95% CI, 5.82–6.29) deaths per 1000 person-years. The adjusted hazard ratio (HR) for all-cause mortality in all vegetarians combined vs non-vegetarians was 0.88 (95% CI, 0.80–0.97). The adjusted HR for all-cause mortality in vegans was 0.85 (95% CI, 0.73–1.01); in lacto-ovo–vegetarians, 0.91 (95% CI, 0.82–1.00); in pesco-vegetarians, 0.81 (95% CI, 0.69–0.94); and in semi-vegetarians, 0.92 (95% CI, 0.75–1.13) compared with nonvegetarians. Significant associations with vegetarian diets were detected for cardiovascular mortality, noncardiovascular noncancer mortality, renal mortality, and endocrine mortality. Associations in men were larger and more often significant than were those in women. Conclusions and Relevance Vegetarian diets are associated with lower all-cause mortality and with some reductions in cause-specific mortality. Results appeared to be more robust in males.

If you are simply trading stocks you will not lose more than you put in, unless you are trading on margin. A limit order is basically that, a limit on the maximum price you want your buy order bought at or the minimum price you want your sell order sold at. If you can't be glued to the screen all day when you place a limit order, and the market moves the opposite way, you may miss out on your order being executed. Even if you can be in front of the screen all day, you then have to decide if you want to chase the market of miss out on your purchase or sale. For example, if a stock is trading at $10.10 and you put a limit buy order to buy 1000 shares at or below $10.00 and the price keeps moving up to $10.20, then $10.30 and then $10.50, until it closes the day at $11.00. You then have the choice during the day to miss out on buying the shares or to increase your limit order in order to buy at a higher price. Sometime if the stock is not very liquid, i.e. it does not trade very often and has low volume, the price may hit $10.00 and you may only have part of your order executed, say 500 out of your 1000 shares were bought. This may mean that you may have to increase the price of your remaining order or be happy with only buying 500 shares instead of 1000. The same can happen when you are selling (but in reverse obviously). With market order, however, you are placing a buy order to buy at the next bid price in the depth or a sell order to sell at the next offer price in the depth. See the market depth table below: Note that this price depth table is taken before market open so it seems that the stock is somewhat illiquid with a large gap between the first and second prices in the buyers (bid) prices. When the market opened this gap is closed, as WBC is a major Australian bank and is quite liquid. (the table is for demonstration purposes only). If we pretend that the market was currently open and saw the current market depth for WBC as above, you could decide to place a limit sell order to sell 1000 shares at say $29.91. You would sell 100 shares straight away but your remaining 900 sell order will remain at the top of the Sellers list. If other Buyers come in at $29.91 you may get your whole sale completed, however, if no other Buyers place orders above $29.80 and other Sellers come into the market with sell orders below $29.91, your remaining order may never be executed. If instead you placed a market sell order you would immediately sell 100 shares at $29.91 and the remaining 900 shares at $29.80. (so you would be $99 or just over 0.3% worse off than if you were able to sell the full 1000 shares at $29.91). The question is how low would you have had to lower your limit order price if the price for WBC kept on falling and you had to sell that day? There are risks with whichever type of order you use. You need to determine what the purpose of your order is. Is it to get in or out of the market as soon as possible with the possibility of giving a little bit back to the market? Or is it to get the price you want no matter how long it takes you? That is you are willing to miss out on buying the shares (can miss out on a good buy if the price keeps rising for weeks or months or even years) or you are willing to miss out on selling them right now and can wait for the price to come back up to the price you were willing to sell at (where you may miss out on selling the shares at a good price and they keep on falling and you give back all your profits and more). Just before the onset of the GFC I sold some shares (which I had bought a few years earlier at $3.40) through a market order for $5.96. It had traded just above $6 a few days earlier, but if instead of a market order I had placed a limit order to sell at $6.00 or more I would have missed out on the sale. The price never went back up to $6 or above, and the following week it started dropping very quickly. It is now trading at about $1.30 and has never gone back above $2.00 (5.5 years later). So to me placing a limit order in this case was very risky.", "title": "" }, { "docid": "389329", "text": "Consider the mechanic which actually drives the 'price' of a stock. In simplest terms, the 'price' of a stock is the price at which the most recent trade occurred. ie: if the price of IBM is $100/share, that means the last time someone bought IBM stock, they paid $100. Above and below the 'spot price', are dozens/hundreds/thousands of buyers and sellers who have placed orders that no one is yet willing to match. ie: if IBM's spot price is at $100, there could still be 10,000 people willing to sell for $101 (called the 'ask' price, for the lowest price someone is currently willing to sell at), and 15,000 willing to buy for $99 (called the 'bid' price, for the highest price someone is currently willing to buy for). Until someone is willing to buy for $101, then no one will be able to sell at $101. Until someone is willing to sell for $99, no one will be able to buy for $99. Typically orders are placed in the market at a particular limit. Meaning that those orders to buy at $99/sell at $101 are already in the 'system', and will be matched immediately as soon as someone is willing to meet the price on the other side. Now consider general market economics: high demand drives up price, and high supply drives down price. If the details above for IBM were yesterday, and today some news came out that IBM was laying off employees, imagine that another 10,000 people who held shares wanted to sell. Now there would be 20,000 sellers and only 15,000 buyers. If those new sellers were aggressive about wanting to sell, they would have to drop their price to $99, to match the highest buyers in the market. Put together, this means that as more sellers enter the market, supply of shares increases, driving down price. Conversely, as more buyers enter the market, demand for shares increases, driving up share price. As a result of the above, you can say that (all else being equal) if price for a stock goes up, there were more buyers that day, and if price goes down, there were more sellers that day. On the face of it, that is not necessarily true, because you could have the same number of buyers and sellers, one side could have simply decreased/increased their acceptable price to match the other side.", "title": "" }, { "docid": "494295", "text": "There are a couple of things you could do, but it may depend partly on the type of orders your broker has available to you. Firstly, if you are putting your limit order the night before after close of market at the top of the bids, you may be risking missing out if bid & offer prices increase by the time the market opens the next day. On the other hand, if bid & offer prices fall at the open of the next day you should get your order filled at or below your limit price. Secondly, you could be available at the market open to see if prices are going up or down and then work out the price you want to buy at then and work out the quantity you can buy at that price. I personally don't like this method because you usually get too emotional, start chasing the market if prices start rising, or start regretting buying at a price and prices fall straight afterwards. My preferred method is this third option. If your broker provides stop orders you can use these to both get into and out of the market. How they work when trying to get into the market is that once you have done your analysis and picked a price that you would want to purchase at, you put a stop buy order in. For example, the price closed at $9.90 the previous day and there has been resistance at $10.00, so you would put a stop buy trigger if the price goes over $10, say $10.01. If your stop buy order gets triggered you can have either a buy market order or a limit order above $10.01 (say $10.02). The market order would go through immediately whilst the limit order would only go through if the price continues going to $10.02 or above. The advantage of this is that you don't get emotional trying to buy your securities whilst sitting in front of the screen, you do your analysis and set your prices whilst the market is closed, you only buy when the security is rising (not falling). As your aim is to be in long term you shouldn't be concerned about buying a little bit higher than the previous days close. On the other hand if you try and buy when the price is falling you don't know when it will stop falling. It is better to buy when the price shows signs of rising rather than falling (always follow the trend).", "title": "" }, { "docid": "259178", "text": "You bought the right – but not the obligation – to buy a certain number of shares at $15 from whomsoever sold you the option, and you paid a premium for it.

If you buy silver at an entrustment price above market price, say x when the market offer is m, then parts of your order will likely be filled at the market price. For the remaining quantity there is now a limit, the bank/broker might fill your order over the next 5 days (or however long the validity is) at various prices, such that the overall average price does not exceed x. This is different to a limit order, as it allows the bank/broker to (partially) buy silver at higher prices than x as long as the overall averages is x or less. In a limit set-up you might be (partially) filled at market prices first, but if the market moves above x the bank/broker will not fill any remaining quantities of your order, so you might end up (after a day or 5 days) with a partially filled order. Also note that an entrustment price below the market price and with a short enough validity behaves like a limit price. The 4th order type is sort of an opposite-side limit price: A stop-buy means buy when the market offer quote goes above a certain price, a stop-sell means sell when the market bid quote goes below a certain price.

At any time T for each product on a (typical) exchange there are two well-defined prices: At time T there is literally no person in the market who wants to sell below the ask, so all the people who are waiting to buy at the bid (or below) could very well be waiting there forever. There's simply no guarantee that any seller will ever want to part with their product for a lesser price than they think it's worth. So if you want to buy the product at time T you have a tough choice to make: you get in line at the bid price, where there's no guarantee that your request will ever be filled, and you might never get your hands on the product you decide that owning the product right now is more valuable to you than (ask - bid) * quantity, so you tell the exchange that you're willing to buy at the ask price, and the exchange matches you with whichever seller is first in line Now, if you're in the market for the long term, the above choice is completely immaterial to you.

Others have said that 1 to 2 years is too short to invest in the stock market as the stock market can have a correction and fall by 50%. But it doesn't matter if you invest for 1 year or if you invest for 50 years, the stock market can still fall by 50% just before you plan to withdraw your funds. What you need to figure out is a way to get out before the market falls by 40% to 50%. A simple way to do this is to use technical indicators to warn you when a market trend is starting to change and that it is time to get out of the market. Two simple indicators you can use on a market index are the Rate of Change (ROC) indicator and the 100 week Moving Average (MA). Below is a 10 year weekly chart of the S&P500 with these two indicators charted. They show good times to get into the market and good times to get out. If you are using the 100 week MA you would buy in when the price crosses above the MA line and sell when the price crosses below the MA line. If you are using the ROC indicator you would buy in when the ROC indicator crosses above the zero line and sell when the ROC indicator crosses below the zero line. So your investment plan could be to buy an Index ETF representing the S&P500 when the ROC moves above zero and sell when it crosses below zero. You can also place a trailing stop loss of 10% to protect you in case of a sudden fall over a couple of days. You can manage your investments in as little as 10 minutes per week by checking the chart once per week and adjusting your stop loss order. If you want to progressively add to your investment each month you could check the charts and only add any new funds if both the ROC is above zero and sloping upwards. Another option for adding new funds could be if the price is above the MA and moving further away from the MA. All these rules should be incorporated into your investment plan so that you are not basing your decisions based on emotions. There are many other Technical Analysis Indicators you could also learn about to make better educated decisions about your stock market investments.

I should point out that your trade is not executed at the limit price. If your limit price on a buy order is higher than the lowest offer, you still get filled at the lowest offer. If before your order is submitted someone fills all offers up to your limit price, you will get your limit price.

It is a historical price – but during market hours, that's usually mere seconds ago for very liquid stocks.

But, think of the bid and ask prices you see as \"\"tip of the iceberg\"\" prices. That is: The \"\"Bid: 13.20 x200\"\" is an indication that there are potential buyers bidding $13.20 for up to 200 shares. Their bids are the highest currently bid; and there are others in line behind with lower bid prices. So the \"\"bid\"\" you're seeing is actually the best bid price at that moment. If you entered a \"\"market\"\" order to sell more than 200 shares, part of your order would likely be filled at a lower price. The \"\"Ask: 13.27 x1,000\"\" is an indication that there are potential sellers asking $13.27 for up to 1000 shares. Their ask prices are the lowest currently asked; and there are others in line behind with higher ask prices. So the \"\"ask\"\" you're seeing is the best asking price at that moment.

A transaction takes place when either a potential buyer is willing to pay the asking price, or a potential seller is willing to accept the bid price, or else they meet in the middle if both buyers and sellers change their orders. Note: There are primarily two kinds of stock exchanges. The one I just described is a typical order-driven matched bargain market, and perhaps the kind you're referring to. The other kind is a quote-driven over-the-counter market where there is a market-maker, as JohnFx already mentioned. In those cases, the spread between the bid & ask goes to the market maker as compensation for making a market in a stock. For a liquid stock that is easy for the market maker to turn around and buy/sell to somebody else, the spread is small (narrow). For illiquid stocks that are harder to deal in, the spread is larger (wide) to compensate the market-maker having to potentially carry the stock in inventory for some period of time, during which there's a risk to him if it moves in the wrong direction. Finally ... if you wanted to buy 1000 shares, you could enter a market order, in which case as described above you'll pay $13.27. If you wanted to buy your shares at no more than $13.22 instead, i.e. the so-called \"\"current\"\" price, then you would enter a limit order for 1000 shares at $13.22.

If you can only afford a few shares, you can still use the information the options market is trying to give you -- see below. A standing limit order to buy a stock is essentially a synthetic short put option position. [1] So deciding on a stock limit order price is the same as valuing an option on that stock. Options (and standing limit orders) are hard to value, and the generally accepted math for doing so -- the Black-Scholes-Merton framework -- is also generally accepted to be wrong, because of black swans. So rather than calculate a stock buy limit price yourself, it's simpler to just sell a put at the put's own midpoint price, accepting the market's best estimate. Options market makers' whole job (and the purpose of the open market) is price discovery, so it's easier to let them fight it out over what price options should really be trading at. The result of that fight is valuable information -- use it. Sell a 1-month ATM put option every month until you get exercised, after which time you'll own 100 shares of stock, purchased at: This will typically give you a much better cost basis (several dollars better) versus buying the stock at spot, and it offloads the valuation math onto the options market. Meanwhile you get to keep the cash from the options premiums as well. Disclaimer: Markets do make mistakes. You will lose money when the stock drops more than the option market's own estimate. If you can't afford 100 shares, or for some reason still want to be in the business of creating synthetic options from pure stock limit orders, then you could maybe play around with setting your stock purchase bid price to (approximately): See your statistics book for how to set ndev -- 1 standard deviation gives you a 30% chance of a fill, 2 gives you a 5% chance, etc. Disclaimer: The above math probably has mistakes; do your own work. It's somewhat invalid anyway, because stock prices don't follow a normal curve, so standard deviations don't really mean a whole lot. This is where market makers earn their keep (or not). If you still want to create synthetic options using stock limit orders, you might be able to get the options market to do more of the math for you. Try setting your stock limit order bid equal to something like this: Where put_strike is the strike price of a put option for the equity you're trading. Which option expiration and strike you use for put_strike depends on your desired time horizon and desired fill probability. To get probability, you can look at the delta for a given option.

Every investment can add or reduce risk, depending on how it's used. If your ordering above is intended to represent the probability you will lose your principal, then it's roughly right, with caveats. If you buy a long-term government bond and interest rates increase while you're holding it, its value will decrease on the secondary markets. If you need/want to sell it before maturity, you may not recover your principal, and if you hold it, you will probably be subject to erosion of value due to inflation (inflation and interest rates are correlated). Over the short-term, the stock market can be very volatile, and you can suffer large paper losses. But over the long-term (decades), the stock market has beaten inflation. But this is true in aggregate, so, if you want to decrease equity risk, you need to invest in a very diversified portfolio (index mutual funds) and hold the portfolio for a long time. With a strategy like this, the stock market is not that risky over time. Derivatives, if used for their original purpose, can actually reduce volatility (and therefore risk) by reducing both the upside and downside of your other investments. For example, if you sell covered calls on your equity investments, you get an income stream as long as the underlying equities have a value that stays below the strike price. The cost to you is that you are forced to sell the equity at the strike price if its value increases above that. The person on the other side of that transaction loses the price of the call if the equity price doesn't go up, but gets a benefit if it does. In the commodity markets, Southwest Airlines used derivatives (options to buy at a fixed price in the future) on fuel to hedge against increases in fuel prices for years. This way, they added predictability to their cost structure and were able to beat the competition when fuel prices rose. Even had fuel prices dropped to zero, their exposure was limited to the pre-negotiated price of the fuel, which they'd already planned for. On the other hand, if you start doing things like selling uncovered calls, you expose yourself to potentially infinite losses, since there are no caps on how high the price of a stock can go. So it's not possible to say that derivatives as a class of investment are risky per se, because they can be used to reduce risk. I would take hedge funds, as a class, out of your list. You can't generally invest in those unless you have quite a lot of money, and they use strategies that vary widely, many of which are quite risky.", "title": "" }, { "docid": "498075", "text": "\"The response to this question will be different depending which of the investment philosophies you are using. Value investors look at the situation the company is in and try to determine what the company is worth and what it will be worth in the future. Then they look at the current stock price and decide whether or not the stock is priced at a good deal or not. If the stock price is priced lower than they believe the company is worth, they would want to buy stock, and if the price rises above what they believe to be the true value, they would sell. These types of investors are not looking at the history or trend of what the price has done in the past, only what the current price is and where they believe the price should be in the future. Technical analysis investors do something different. It is their belief that as stock prices go up and down, they generally follow patterns. By looking at a chart of what a stock price has been in the past, they try to predict where it is headed, and buy or sell based on that prediction. In general, value investors are longer-term investors, and technical analysis investors are short-term investors. The advice you are considering makes a lot of sense if you are using technical analysis. If you have a stock that is trending down, your strategy probably tells you to sell; buying more in the hopes of turning things around would be seen as a mistake. It is like the gambler in Vegas who keeps playing a game he is losing, hoping that his luck changes. However, for the value investor, the historical price of a stock, and even the amount you currently have gained or lost in the stock, are essentially ignored. All that matters is whether or not the stock price is above or below the true value determined by the investor. For him, if the stock price falls and he believes the company still has a high value, it could be a signal to buy more. The above advice doesn't really apply for them. Many investors don't follow either of these strategies. They believe that it is too difficult and risky to try to predict the future price of an individual stock. Instead, they invest in many companies all at once using index mutual funds, believing that the stock market as a whole always heads up over a long time frame. Those investors don't care at all if the prices of stock are going up or down. They simply keep investing each month, and hold until they have another use for the money. The above advice isn't useful for them at all. No matter which kind of investing you are doing, the most important thing is to pick a strategy you believe in and follow the plan without emotion. Emotions can cause investors to make mistakes and start buying when their strategy tells them to sell. Instead of trying to follow fortune cookie advice like \"\"Don't throw good money after bad,\"\" choose an investment strategy, make a plan, test it, and follow it, cautiously (after all, it may be a bad plan).

The order will be placed in the market and when the price reaches $110 your order will be executed. If the price gaps at the open to $111, then you would end up selling for $111. In other words you will get a minimum of $110 per share. A stop limit order is where you put a stop loss order, which when it gets triggered, will place a limit order in the market for you. For example, you want to limit your losses by placing a stop loss order if the price drops to $90. If you chose a market order with your stop loss as soon as the price hits $90 your stop loss would be triggered and the shares would sell at the next available price, usually at $90, but could be less if the market gaps down past $90. If on the other hand you placed a limit order at $89.50 with your stop loss, when the stop loss order gets triggered at $90 your limit order will be placed into the market to sell at $89.50.

Other indicators or candlestick patters can also be used to further confirm the trade. Below is a chart of a trade I recently took on GUD.AX using the Slow Stochastic in combination with support and resistance levels as well as a candlestick pattern. When I conducted my stock search on the evening of 28th July 2015, GUD was one of the results from the search that I particularly liked. The Slow Stochastic had just made a crossover in the oversold area just as the price was bouncing off its recent lows at the support line. But what I really like about this opportunity was that there was also a bullish reversal candle (a Hammer) at this short term market bottom. The high for the day was $8.34, so I placed a stop buy order to buy the stock tomorrow if the price opened or moved above this high of today. So I would only buy if the stock hit or moved above $8.35 during the next days trading. So if the stock opened and stayed below the previous day's high I would not buy the stock and my order would be canceled at the end of the day. This is very important because it stops you from getting into trades that don't go in the direction you want. If this happens then you could check the chart again after market close to see if it is still worthwhile to place a new order for the next day. On the 29th July 2015 the stock did open higher at $8.42 (which is where my order got executed) and closed at $8.46. So I ended up buying slightly above my target price but it did move higher on the day, so a successful entry overall. I had placed my initial stop loss at $8.09 (just below the low of the previous day of $8.10). If the trade had gone against me in the following days the most I would have lost was 1% of my total account capital. My target for this trade was $9.86 (just below the resistance line near $10), which would represent a 5% gain against my total account capital (or approx. 16.7% gain on the trade). So my win to loss ratio was 5:1. As you can see from the chart, the next day gapped up at the open and prices continued moving up strongly during the day. The next day was a slightly negative day, and then a few days later, on the 5th August 2015 my target price of $9.86 was reached (with a high of $9.88 for that day), so my order was closed for a total profit of 16.7% on the face value of the trade. However, as I bought on margin (using CFDs) my actual profit on the initial margin I had invested was 167%. My total time in the trade was 7 days, and I spent about an hour in the evening doing my searches and placing my orders, then less than 10 minutes managing the trade each evening after market close. The stock did go up a bit further after my profit target was reached, but the day after that the price started to fall as the price hit the resistance line and the Slow Stochastic did a crossover in the overbought area. Overall, this was a very ideal trade and I was very happy with it. Not all my trades reach my profit targets and I may get stopped out at a smaller profit or I might make a small loss (as I move my stops up as the price moves up). The key to successful trading over the long term is to keep you losses small and let your profits run (with my longer term trend trading I don't have profit targets and let my profits run until I get stopped out, but with my shorter term trading I do use a profit target usually 5 or 6 times the size of my initial stop).

In an free and open market, investments that are certain to generate above-average profits would do so by being sold cheaply, while having a high return on investment after that. But in a free market, prices are set by supply and demand. There is a high demand and little supply for investments that would certainly outperform the market. The demand is in fact so high, that the purchase price rises to the point of eliminating that excess return. And with high-frequency automated trading, that price hike is instant. But who would even want to sell such guaranteed outperformers in the first place? Of course, there are uncertainties associated with stocks, and individual stocks therefore move independently. As \"\"the market\"\" is an average, some stocks will therefore beat the market over certain time periods. That's random statistical variation. The only realistic path to above-average returns is to accept higher risks. As discussed above, nobody wants to sell you safe bets. But risky bets are another matter. Different actors will price risk differently. If you aren't worried much about risk, you can pick up stocks that are cheap by your standards. That is possible only because such stocks aren't cheap by risk-averse standards. Looking a bit deeper, we see that arbitrage works in a free market because there's essentially perfect information. But risk is precisely the absence of such information, and that can lead to price variations. Yet, as the lack of information means a lack of certainty, you can't use this to reliably beat the market.\"", "title": "" }, { "docid": "494727", "text": "\"Re: A trader when buying needs to buy at the ask price and when selling needs to sell at the bid price. So how can a trade happen 'in between' the bid and ask? Saying the trade can happen \"\"in between\"\" the bid & ask is simplistic. There is a time dimension to the market. It's more accurate to say that an order can be placed \"\"in between\"\" the current best bid & ask (observed at time T=0), thus establishing a new level for one or the other of those quoted prices (observed at time T>0). If you enter a market order to buy (or sell), then yes, you'll generally be accepting the current best ask (or best bid) with your order, because that's what a market order says to do: Accept the current best market price being offered for your kind of transaction. Of course, prices may move much faster than your observation of the price and the time it takes to process your order – you're far from being the only participant. Market orders aside, you are free to name your own price above or below the current best bid & ask, respectively. ... then one could say that you are placing an order \"\"in between\"\" the bid and ask at the time your order is placed. However – and this is key – you are also moving one or the other of those quoted prices in the process of placing your above-bid buy order or your below-ask sell order. Then, only if somebody else in the market chooses to accept your new ask (or bid) does your intended transaction take place. And that transaction takes place at the new ask (or bid) price, not the old one that was current when you entered your order. Read more about bid & ask prices at this other question: (p.s. FWIW, I don't necessarily agree with the assertion from the article you quoted, i.e.: \"\"By looking for trades that take place in between the bid and ask, you can tell when a strong trend is about to come to an end.\"\" I would say: Maybe, perhaps, but maybe not.)\"", "title": "" }, { "docid": "31933", "text": "The Limit Order are matched based on amount and time.

Now the highest price the buyer is ready to pay is 20.21 and the lowest price a seller is ready to sell for is 20.25. Hence there is no trade. Now if a new Buy order comes in at 20.25, it matches with the sell and the deal is made. If a new Buy order comes in at 20.30, it still matches at 20.25. Similarly if a Sell order come in at 20.21, it matches and a deal is made. If a Sell order come in at 20.11, it still matches 20.21. Incase of market order, with the above example if there is a Buy order, it would match with the lowest sell order at 20.25, if there is not enough quantity , it would match the remaining quantity to the next highest at 20.31 and continue down. Similarly if there is a Sell market order, the it would match to the maximum a seller is ready to buy, ie 20.21, if there is not sufficient buy quantity at 20.21, it will match with next for 20.19 If say there are new buy order at 20.22 and sell orders at 20.24, these will sit first the the above queue to be matched.

However if the Buy order was first ie at t1 there was a buy order for 20.21 and then at time later than t1, there is a sell order for say 20.10 [amount less than or equal to 20.21] it would match for 20.21.

Now there are multiple things, the Buyer knows the lowest Sell order is at $10, he can put a matching Buy order at $10 Qty 100, and say $11 Qty 100 etc. This is painful. Second, lets say he puts a Buy order at $10 Qty 100, by the time the order hits the system someone else has put the trade at $10 and his order is fulfilled. So this buyer has to keep looking at booking and keep making adjustments, if its a large order, it would be extremely difficult and frustrating for this Buyer. Hence the logic of giving preference.

The NYSE has \"\"specialists\"\" that are market makers that also performed a few other roles in the management of trading for a stock, and usually a single issue on the NYSE is covered by only one market maker. Market makers are often middlemen between brokers (ignoring stuff like dark pools, and the fact that brokers will often trade stocks internally among their own clients before going to the exchange). Historically, the market makers gave up buy/sell discretion in exchange for being the \"\"go-to guys\"\" for anyone wanting to trade in that stock. When you told your broker to buy a stock for you, he didn't hook you up with another retail investor; he went to the market maker.

They were like other floor traders; they hung out on the exchange floors and interacted with traders to buy and sell stocks. Traders came to them when they wanted to buy one of the specialist's issues. There was no public order book; just ticker tape and a quote. It was up to the market maker to maintain that order book.

From the WSJ: Another factor behind the shift has been the proliferation of passively managed investments, such as index funds. These funds aim to mimic an index, like the S&P 500, by owning the shares that comprise it. Index funds don’t trade as often as active investors, but when they do, it is typically near the market close, traders say. That is because buying or selling a stock at its closing price better aligns their performance with the index they are trying to emulate. The second reason is simply that volume attracts volume.

How are bonds affected by the Federal Funds Rate?
[ { "docid": "577578", "text": "\"The federal funds rate is one of the risk-free short-term rates in the economy. We often think of fixed income securities as paying this rate plus some premia associated with risk. For a treasury security, we can think this way: (interest rate) = (fed funds rate) + (term premium) The term premium is a bit extra the bond pays because if you hold a long term bond, you are exposed to interest rate risk, which is the risk that rates will generally rise after you buy, making your bond worth less. The relation is more complex if people have expectations of future rate moves, but this is the general idea. Anyway, generally speaking, longer term bonds are exposed to more interest rate risk, so they pay more, on average. For a corporate bond, we think this way: (interest rate) = (fed funds rate) + (term premium) + (default premium) where the default premium is some extra that the bond must pay to compensate the holder for default risk, which is the risk that the bond defaults or loses value as the company's prospects fall. You can see that corporate and government bonds are affected the same way (approximately, this is all hand-waving) by changes in the fed funds rate. Now, that all refers to the rates on new bonds. After a bond is issued, its value falls if rates rise because new bonds are relatively more attractive. Its value rises if rates on new bonds falls. So if there is an unexpected rise in the fed funds rate and you are holding a bond, you will be sad, especially if it is a long term bond (doesn't matter if it's corporate or government). Ask yourself, though, whether an increase in fed funds will be unexpected at this point. If the increase was expected, it will already be priced in. Are you more of an expert than the folks on wall-street at predicting interest rate changes? If not, it might not make sense to make decisions based on your belief about where rates are going. Just saying. Brick points out that treasuries are tax advantaged. That is, you don't have to pay state income tax on them (but you do pay federal). If you live in a state where this is true, this may matter to you a little bit. They also pay unnaturally little because they are convenient for use as a cash substitute in transactions and margining (\"\"convenience yield\"\"). In general, treasuries just don't pay much. Young folk like you tend to buy corporate bonds instead, so they can make money on the default and term premia.\"", "title": "" }, { "docid": "214710", "text": "\"I'll answer your question, but first a comment about your intended strategy. Buying government bonds in a retirement account is probably not a good idea. Government bonds (generally) are tax advantaged themselves, so they offer a lower interest rate than other types of bonds. At no tax or reduced tax, many people will accept the lower interest rate because their effective return may be similar or better depending, for example, on their own marginal tax rate. In a tax-advantaged retirement account, however, you'll be getting the lower interest without any additional benefit because that account itself is already tax-advantaged. (Buying bonds generally may be a good idea or not - I won't comment on that - but choose a different category of bonds.) For the general question about the relationship between the Fed rate and the bond rate, they are positively correlated. There's not direct causal relationship in the sense that the Fed is not setting the bond rate directly, but other interest bearing investment options are tied to the Fed rate and many of those interest-bearing options compete for the same investor dollars as the bonds that you're reviewing. That's at a whole market level. Individual bonds, however, may not be so tightly coupled since the creditworthiness of the issuing entity matters a lot too, so it could be that \"\"bond rates\"\" generally are going up but some specific bonds are going down based on something happening with the issuer, just like the stock market might be generally going up even as specific stocks are dropping. Also keep in mind that many bonds trade as securities on a secondary market much like stocks. So I've talked about the bond rate. The price of the bonds themselves on the secondary market generally move opposite to the rate. The reason is that, for example, if you buy a bond at less than face value, you're getting an effective interest rate that's higher because you get the same sized incremental payments of interest but put less money into the investment. And vice versa.\"", "title": "" } ]
[ { "docid": "285064", "text": "Fundamentally interest rates reflect the time preference people place on money and the things money can buy. If I have a high time preference then I prefer money in my hand versus money promised to me at some date in the future. Thus, I will only loan my money to someone if they offer me an incentive which would be an amount of money to be received in the future that is larger than the amount of money I’m giving the debtor in the present (i.e. the interest rate). Many factors go into my time preference determination. My demand for cash (i.e. my cash balance), the credit rating of the borrower, the length of the loan, and my expectation of the change in currency value are just a few of the factors that affect what interest rate I will loan money. The first loan I make will have a lower interest rate than the last loan, ceteris paribus. This is because my supply of cash diminishes with each loan which makes my remaining cash more valuable and a higher interest rate will be needed to entice me to make additional loans. This is the theory behind why interest rates will rise when QE3 or QEinfinity ever stops. QE is where the Federal Reserve cartel prints new money to purchase bonds from cartel banks. If QE slows or ends the supply of money will stop increasing which will make cash more valuable and higher interest rates will be needed to entice creditors to loan money. Note that increasing the stock of money does not necessarily result in lower interest rates. As stated earlier, the change in value of the currency also affects the interest rate lenders are willing to accept. If the Federal Reserve cartel deposited $1 million everyday into every US citizen’s bank account it wouldn’t take long before lenders demanded very high interest rates as compensation for the decrease in the value of the currency. Does the Federal Reserve cartel affect interest rates? Yes, in two ways. First, as mentioned before, it prints new money that is loaned to the government. It either purchases the bonds directly or purchases the bonds from cartel banks which give them cash to purchase more government bonds. This keeps demand high for government bonds which lowers the yield on government bonds (yields move inverse to the price of the bond). The Federal Reserve cartel also can provide an unlimited amount of funds at the Federal Funds rate to the cartel member banks. Banks can borrow at this rate and then proceed to make loans at a higher rate and pocket the difference. Remember, however, that the Federal Reserve cartel is not the only market participant. Other bond holders, such as foreign governments and pension funds, buy and sell US bonds. At some point they could demand higher rates. The Federal Reserve cartel, which currently holds close to 17% of US public debt, could attempt to keep rates low by printing new money to buy all existing US bonds to prevent the yield on bonds from going up. At that point, however, holding US dollars becomes very dangerous as it is apparent the Federal Reserve cartel is just a money printing machine for the US government.

If the fed opts to raise or lower this rate, it subsequently effects all interest rates, whether by being directly connected in a chain of loans or by market demand through the efficiency of financial markets in the case of bond auctions. The FOMC meets eight times each year to determine the target for the federal funds rate. The federal funds rate effects all interest rates because it is the originating rate of interest on all loans in the chain of loans. Because of this significance as a benchmark for all interest rates, it is the rate most commonly referred to as \"\"interest rate\"\" when used alone. That is why other rates are specified by what they actually are; e.g., mortgage rates; 10 year & 30 year (for 10 year treasury and 30 year treasury bond yields respectively); savings rate, auto rate, credit card rate, CD rate—all rates of interest effected by the originating loan that is the federal funds rate. This is true in the United States but will vary for other countries. In general though, it will almost always refer to the originating rate for all loans in a given country, institution, etc. Note that bonds have yields that are based on market demand that is, in turn, based on the federal funds rate. It is because of the efficiency of financial markets that the demand, and thus the yields, are correlated to the federal funds rate.\"", "title": "" }, { "docid": "455398", "text": "Sounds like a bad idea.

Interest rates What you should know is that the longer the \"\"term\"\" of a bond fund, the more it will be affected by interest rates. So a short-term bond fund will not be subject to large gains or losses due to rate changes, an intermediate-term bond fund will be subject to moderate gains or losses, and a long-term bond fund will be subject to the largest gains or losses. When a book or financial planner says to buy \"\"bonds\"\" with no other qualification, they almost always mean investment-grade intermediate-term bond funds (or for individual bonds, the equivalent would be a bond ladder averaging an intermediate term). If you want technical details, look at the \"\"average duration\"\" or \"\"average maturity\"\" of the bond fund; as a rough guide, if the duration is 10, then a 1% change in interest rates would be a 10% gain or loss on the fund. Another thing you can do is look at long-term (10 years or ideally longer) performance history on some short, intermediate, and long term bond index funds, and you can see how the long term funds bounced around more. Non-investment-grade bonds (aka junk bonds or high yield bonds) are more affected by factors other than interest rates, including some of the same factors (economic booms or recessions) that affect stocks. As a result, they aren't as good for diversifying a portfolio that otherwise consists of stocks. (Having stocks, investment grade bonds, and also a little bit in high-yield bonds can add diversification, though. Just don't replace your bond allocation with high-yield bonds.) A variety of \"\"complicated\"\" bonds exist (convertible bonds are an example) and these are tough to analyze. There are also \"\"floating rate\"\" bonds (bank loan funds), these have minimal interest rate sensitivity because the rate goes up to offset rate rises. These funds still have credit risks, in the credit crisis some of them lost a lot of money. 2. Diversification The purpose of diversification is risk control. Your non-bond funds will outperform in many years, but in other years (say the -37% S&P 500 drop in 2008) they may not. You will not know in advance which year you'll get. You get risk control in at least a few ways. There's also an academic Modern Portfolio Theory explanation for why you should diversify among risky assets (aka stocks), something like: for a given desired risk/return ratio, it's better to leverage up a diverse portfolio than to use a non-diverse portfolio, because risk that can be eliminated through diversification is not compensated by increased returns. The theory also goes that you should choose your diversification between risk assets and the risk-free asset according to your risk tolerance (i.e. select the highest return with tolerable risk). See http://en.wikipedia.org/wiki/Modern_portfolio_theory for excruciating detail. The translation of the MPT stuff to practical steps is typically, put as much in stock index funds as you can tolerate over your time horizon, and put the rest in (intermediate-term investment-grade) bond index funds. That's probably what your planner is asking you to do. My personal view, which is not the standard view, is that you should take as much risk as you need to take, not as much as you think you can tolerate: http://blog.ometer.com/2010/11/10/take-risks-in-life-for-savings-choose-a-balanced-fund/ But almost everyone else will say to do the 80/20 if you have decades to retirement and feel you can tolerate the risk, so my view that 60/40 is the max desirable allocation to stocks is not mainstream. Your planner's 80/20 advice is the standard advice.

You have a few options here. I won't make a specific recommendation, but will present some options and hopefully useful information. Here's the short story: To buy individual stocks, you need to go through a broker. These brokers charge a fee for every transaction, usually in the neighborhood of $7. Since you probably won't want to just buy and hold a single stock for 15 years, the fees are probably unreasonable for you. If you want the educational experience of picking stocks and managing a portfolio, I suggest not using real money. Most mutual funds have minimum investments on the order of a few thousand dollars. If you shop around, there are mutual funds that may work for you. In general, look for a fund that: An example of a fund that meets these requirements is SWPPX from Charles Schwabb, which tracks the S&P 500. Buy the product directly from the mutual fund company: if you go through a broker or financial manager they'll try to rip you off. The main advantage of such a mutual fund is that it will probably make your daughter significantly more money over the next 15 years than the safer options. The tradeoff is that you have to be prepared to accept the volatility of the stock market and the possibility that your daughter might lose money. Your daughter can buy savings bonds through the US Treasury's TreasuryDirect website. There are two relevant varieties: You and your daughter seem to be the intended customers of these products: they are available in low denominations and they guarantee a rate for up to 30 years. The Series I bonds are the only product I know of that's guaranteed to keep pace with inflation until redeemed at an unknown time many years in the future. It is probably not a big concern for your daughter in these amounts, but the interest on these bonds is exempt from state taxes in all cases, and is exempt from Federal taxes if you use them for education expenses. The main weakness of these bonds is probably that they're too safe. You can get better returns by taking some risk, and some risk is probably acceptable in your situation. Savings accounts, including so-called \"\"money market accounts\"\" from banks are a possibility. They are very convenient, but you might have to shop around for one that: I don't have any particular insight into whether these are likely to outperform or be outperformed by treasury bonds. Remember, however, that the interest rates are not guaranteed over the long run, and that money lost to inflation is significant over 15 years. Certificates of deposit are what a bank wants you to do in your situation: you hand your money to the bank, and they guarantee a rate for some number of months or years. You pay a penalty if you want the money sooner. The longest terms I've typically seen are 5 years, but there may be longer terms available if you shop around. You can probably get better rates on CDs than you can through a savings account. The rates are not guaranteed in the long run, since the terms won't last 15 years and you'll have to get new CDs as your old ones mature. Again, I don't have any particular insight on whether these are likely to keep up with inflation or how performance will compare to treasury bonds.

Even after all that the US has been through (and is still going through), the United States dollar is widely regarded as one of the safest safe havens for your money. As such it serves as a de facto baseline against which all other investments can be measured, the bar everyone has to pass: if you could earn 4% on a 5-year US Treasury bond, or earn 4% on anything else over the next 5 years, you pick the Treasury bond. In many ways this means that the interest rate on a Treasury bond is the closest single measure we have to the price of money all by itself. If someone is loaning you money, they could be loaning it to the Treasury instead; they are losing out by making this loan to you, and must charge you at least this rate just to break even. But most people/governments/countries aren't as credit-worthy as the US Treasury. A few are (the US treasury isn't magical, after all, just really good at what it does), but generally they are not. There is a possibility when loaning money to these entities that you will not get your money back. That is risk. All entities have some risk (even the US treasury!), and some have more than others; \"\"junk bonds\"\" have a somewhat elevated level of this risk. Now, you don't just take a risk on for free (unless you're being charitable or something, but I hope you can find better beneficiaries of charity than the average junk bond). You need to be compensated for that risk. Lenders will demand compensation commensurate with that risk - or they will just walk away without making any loans or buying any bonds because it's not worth it. The difference between the interest rate on a US Treasury bond and the interest rate on another bond, such as a junk bond, is the risk premium - the cost of carrying that risk. Therefore you can see that the interest rate on a junk bond is the price of money plus the risk premium. Now, the Federal Reserve adjusts the price of money from time to time, by buying and selling US Treasury bonds until the price is something they like. This means that one component of interest rate on a junk bond is the interest rate on the US Treasury bond, and it is effectively controlled by the Federal Reserve (through that layer of indirection). The other component of the interest rate on a junk bond is the risk premium. It's not generally possible to know in advance whether or not some company will actually default. People have to guess, and decide how comfortable they are taking that risk. This means that risk is more expensive (and interest rates are higher) when they think the companies in question are going through some hard times, and risk will also be more expensive when people decide that they can't take as many risks (perhaps they've already lost some money and need to take additional steps to protect the rest). It's definitely very hard for an individual to decide what the risk on a particular bond is. The good news is that you generally don't have to. There are a bunch of rich jerks, hedge funds, retirement funds, insurance companies, and other investment entities out there who spend all day looking at things like bonds, trying to estimate the risk. Their willingness to exploit minuscule differences between the interest rate on a bond and the real risk means that the average bond on the market will be fairly priced, according to what all those people think. Plenty of them can still be wrong, mind you (cf. mortgage-backed securities) but in the general case the price of any security reflects all the information everyone in the world has on it on average, so if you're wrong you're in good company. When you buy a nice diversified bond fund, you have access to a bunch of bonds at a pretty-standard price. So that's interest rates for you. But you asked about prices. As it turns out, they're the same thing! - just expressed slightly differently. One way or another a bond is essentially meant to be a stream of payments worth a certain amount in the end - this is why you'll hear them referred to sometimes as a \"\"fixed-income security\"\". The interest rate is essentially the difference between the price you pay now, and the value you receive later, except expressed as a rate. Technically, you could structure the bonds differently (e.g. does the bond pay little bits of interest as you go along, or just pay one big lump sum in the end?) but you can use Math to convert between these two situations, and figure out how much money is worth which when, so it doesn't really matter. Anyway. This means that rising interest rates means lower bond prices on bonds you already own (and falling interest rates means higher bond prices). So if the Federal Reserve increases interest rates, the face value of your bond funds will fall. Also, if people think that the companies issuing the bonds are too risky, the face value of those bonds will also fall. (You were probably expecting the latter effect, though.) Mind you, you will still get the same amount of future money out of them as you would otherwise: that's why they're fixed-income securities. However, a higher interest rate means \"\"I can get more money in the future for less money now\"\", and so people will be willing to pay you less for your bond in the present. This is known as interest rate risk. It is higher on longer term bonds, because those have more time to earn interest.\"", "title": "" }, { "docid": "388391", "text": "\"So \"\"Operation Twist\"\" is actually a pretty simple concept. Here's the break down: The Fed sells short-term treasury bonds that it already holds on its books. Short-term treasury bonds refer to - bonds that mature in less than three years. Then: Uses that money to buy long term treasury bonds. Long-term treasury bonds refer to - bonds that mature in six to 30 years The reason: The fed buys these longer-term treasuries to lower longer-term interest rates and encourage more borrowing and spending. Diving deeper into how it works: So the Fed can easily determine short-term rates by using the Federal funds rate this rate has a direct effect on the following: However this does not play a direct role in influencing the rate of long-term loans (what you might pay on a 30-year fixed mortgage). Instead, long-term rates are determined by investors who buy and sell bonds in the bond market, which changes daily. These bond yields fluctuate depending on the health of the economy and inflation. However, the Fed funds rate does play an indirect role in these rates. So now that we know a little more about what effects what rate, why does lower long-term rates in treasuries influence my 30yr fixed mortgage? Well when you are looking for a loan you are entering a market and competing against other people, by people I mean anyone looking for money (e.g: my grandmother, companies, or the US government). The bank that lends you money has to decide weather the deal you are offering them is better then another deal on the market. If the risk of lending to one person is the same as the risk of lending to another, the bank will make whichever loan yields the higher interest rate. The U.S. government is considered a very safe borrower, so much so that government bonds are considered almost “risk free”, but because of the lower risk the rate of return is lower. So now the bank has to factor in this risk and make its decision weather to lend you money, or the government. So, if the government were to go to the market and buy its own long-term bonds it is adding demand in the market causing the price of the bond to rise in effect lowering the interest rate (when price goes up, yield goes down). So when you go back and ask for a loan it has to re-evaluate and decide \"\"Is it worth giving this money to Joe McFreeBeer instead and collecting a higher yield?\"\" (After all, Joe McFreeBeer is a nice guy). Here's an example: Lets say the US has a rating of 10 out of 10 and its bonds pay a 2% yield. Now lets say for each lower mark in rating the bank will lend at a minimum of 1% higher and your rating is 8 of 10. So if you go to market, the lowest rate you can get will be 4%. Now lets say price rises on the US treasury and causes the rate to go down by 1%. In this scenario you will now be able to get a loan for 3% and someone with a rating of 7 of 10 would be able to get that 4% loan.

Companies with junk credit ratings have lousy balance sheets, so negative economic conditions or tight short term debt markets can result in default for many of these companies.

Typically banks are involved in loaning out money to businesses, people, and government at a higher interest rate then what they are paying to depositors. This is the spread and how they make money. If the bank determines that the yields on government bonds is more attractive then loaning the money out to businesses and people then the bank will purchase government bonds. It can also decide the other way. In this manner the mortgage and bond markets are always competing for capital and tend to offer very similar yields. Certain banks have the unique privilege of being able to borrow money from the FED at the Federal Funds rate and use this money to purchase government debt or loan it out to other banks or purchase other debt products. In this manner you see a high correlation between the FED funds rate, mortgage rates, and treasury yields. Other political factors include legislation that encourages mortgage lending (see Community Reinvestment Act) where banks may not have made the loans without said legislation.

These buyers and sellers decide what and how to trade based on the probability of future events, as they see it. That's a simple statement, but an example demonstrates how complicated it can be. Picture a company that's about to announce earnings. Some investors/traders (from here on, \"\"agents\"\") will have purchased the company's stock a while ago, with the expectation that the company will have strong earnings and grow going forward. Other agents will have sold the stock short, bought put options, etc. with the expectation that the company won't do as well in the future. Still others may be unsure about the future of the company, but still expecting a lot of volatility around the earnings announcement, so they'll have bought/sold the stock, options, futures, etc. to take advantage of that volatility. All of these various predictions, expectations, etc. factor into what agents are bidding and asking for the stock, its associated derivatives, and other securities, which in turn determines its price (along with overall economic factors, like the sector's performance, interest rates, etc.) It can be very difficult to determine exactly how markets are factoring in information about an event, though. Take the example in your question. The article states that if market expectations of higher interest rates tightened credit conditions... In this case, lenders could expect higher interest rates in the future, so they may be less willing to lend money now because they expect to earn a higher interest rate in the future. You could also see this reflected in bond prices, because since interest rates are inversely related to bond prices, higher interest rates could decrease the value of bond portfolios. This could lead agents to sell bonds now in order to lock in their profits, while other agents could wait to buy bonds because they expect to be able to purchase bonds with a higher rate in the future. Furthermore, higher interest rates make taking out loans more expensive for individuals and businesses. This potential decline in investment could lead to decreased revenue/profits for businesses, which could in turn cause declines in the stock market. Agents expecting these declines could sell now in order to lock in their profits, buy derivatives to hedge against or ride out possible declines, etc. However, the current low interest rate environment makes it cheaper for businesses to obtain loans, which can in turn drive investment and lead to increases in the stock market. This is one criticism of the easy money/quantitative easing policies of the US Federal Reserve, i.e. the low interest rates are driving a bubble in the stock market. One quick example of how tricky this can be. The usual assumption is that positive economic news, e.g. low unemployment numbers, strong business/residential investment, etc. will lead to price increases in the stock market as more agents see growth in the future and buy accordingly. However, in the US, positive economic news has recently led to declines in the market because agents are worried that positive news will lead the Federal Reserve to taper/stop quantitative easing sooner rather than later, thus ending the low interest rate environment and possibly tampering growth. Summary: In short, markets incorporate information about an event because the buyers and sellers trade securities based on the likelihood of that event, its possible effects, and the behavior of other buyers and sellers as they react to the same information. Information may lead agents to buy and sell in multiple markets, e.g. equity and fixed-income, different types of derivatives, etc. which can in turn affect prices and yields throughout numerous markets.\"", "title": "" }, { "docid": "548971", "text": "Mortgage rates generally consist of two factors: The risk premium is relatively constant for a particular individual / house combination, so most of the changes in your mortgage rate will be associated with changes in the price of money in the world economy at large.

Stock funds and bonds funds collect income dividends in different ways. Stock funds collect dividends (as well as any capital gains that are realized) from the underlying stocks and incorporates these into the funds’ net asset value, or daily share price. That’s why a stock fund’s share price drops when the fund makes a distribution – the distribution comes out of the fund’s total net assets. With bond funds, the internal accounting is different: Dividends accrue daily, and are then paid out to shareholders every month or quarter. Bond funds collect the income from the underlying bonds and keep it in a separate internal “bucket.” A bond fund calculates a daily accrual rate for the shares outstanding, and shareholders only earn income for the days they actually hold the fund. For example, if you buy a bond fund two days before the fund’s month-end distribution, you would only receive two days’ worth of income that month. On the other hand, if you sell a fund part-way through the month, you will still receive a partial distribution at the end of the month, pro-rated for the days you actually held the fund. Source Also via bogleheads: Most Vanguard bond funds accrue interest to the share holders daily. Here is a typical statement from a prospectus: Each Fund distributes to shareholders virtually all of its net income (interest less expenses) as well as any net capital gains realized from the sale of its holdings. The Fund’s income dividends accrue daily and are distributed monthly. The term accrue used in this sense means that the income dividends are credited to your account each day, just like interest in a savings account that accrues daily. Since the money set aside for your dividends is both an asset of the fund and a liability, it does not affect the calculated net asset value. When the fund distributes the income dividends at the end of the month, the net asset value does not change as both the assets and liabilities decrease by exactly the same amount.

You need to first assess how your stuff is invested, if for example half is in stocks, and the other half is in bonds, then you will need to calculate a 'blended' rate for what are reasonable 'average return' for both. That might mean looking at the S&P500 or Russell 3000 for the stock portion, and some bond index for that portion, then 'blend the rates', in this case using a formula like this then compare the blended rate with the return in your IRA. It is generally a lot more useful to compare the various components of your total return separately, especially if you investing with a particular style such as 'agressive growth' or you are buying actual bonds and not a bond fund since most of the bond oriented indexes are for bond funds, which you can't really compare well with buying and holding bonds to maturity. Lets say your stock side was two mutual funds with different styles, one 'large cap' the other 'aggressive growth'. In that case you might want to compare each one of those funds with an appropriate index such as those provided by Morningstar If you find one of them is consistently below the average, you might want to consider finding an alternative fund who's manager has a better track record (bearing in mind that \"\"past performance....\"\") For me (maybe someone has a good suggestion here) bonds are the hard thing to judge. The normal goal of actually owning bonds (as opposed to a fund) is to retain the entire principal value because there's no principal fluctuation if you hold the bond to maturity (as long as you choose well and the issuer doesn't default) The actual value 'right now' of a bond (as in selling before maturity) and bond funds, goes up and down in an inverse relationship with interest rates. That means the indexes for such things also go up and down a lot, so it's very hard to compare them to a bond you intend to hold to maturity. Also, for such a bond, there's not a lot of point to 'switch out' unless you are worried about the issuer defaulting. If rates are up from what you are getting on your bonds, then you'll have to sell your bond at a discount, and all that happens is you'll end up holding a different bond that is worth less, but has higher interest (basically the net return is likely to be pretty much the same). The better approach there is generally to 'ladder' your maturity dates so you get opportunities to reinvest at whatever the prevailing rates are, without having to sell at a discount.. anyway the point is that I'm not sure there's a lot of value to comparing return on the bond portion of an IRA unless it's invested in bond funds (which a lot of people wanting to preserve principal tend to avoid)\"", "title": "" }, { "docid": "317667", "text": "Sure thing - Treasuries Bonds/Bills are what the US Gov uses to borrow. However it's slightly different than taking out a loan. It's basically an agreement to give (repay) a set sum of money at a certain time in the future in exchange for a sum of funding that's determined by market forces (supply &amp; demand). The difference between today's price and the payment in the future is the interest. For example (completely made up numbers): - Today is 08/05/2017 - The government issues a bond that say it will pay who ever owns this bond $105 on 08/05/**2018** - The market decides that $105 from the US government paid a year from now is worth $100 today. In other words the US Government is borrowing for one year at a rate of 5% (105 - 100) / 100 = .05 = 5% Now consider Saudi Arabia's petroleum company, Aramco. Because petroleum is traded in dollars, when Aramco makes a sale, its paid in USD. Some of that is going to be reinvested into the company, some paid out in dividends to share holders but inevitably some of that will be saved someplace where it can make interest. Because treasuries are traded/issued in dollars and because Aramco's businesses deals primarily in dollars, treasuries are the natural place to store that savings, especially because the market considers them extremely safe. If they exchange the USD into the Saudi currency to store the money in Saudi assets, Aramco is subject to *exchange rate risk*. If the riyal depreciates relative to the dollar, Aramco will lose wealth on the exchange back to dollars when they go to move those funds back into their business. It's in their interest to deal with assets denominated in USD (i.e. T-Bonds) in order to avoid this. So now because the Saudis want T-Bonds as well, the additional demand pushes the market price of our bond from $100 to $102. And the effective one year borrowing rate for the Government goes from 5% to 2.9%. (105 - 102)/102 = .029411 = 2.9% And there you have it, cheaper borrowing.

A bond is an asset, and like any tradeable asset it has a price. If I hold $10K face value of a certain GM bond, then I would be willing to sell it at some price, which may be more or less than $10K. Whoever is willing to sell it for the lowest amount determines the price. The price is determined by the market, just as all prices are. It's what you can sell a bond for. Bond prices may be quoted in various funny ways, like as a discount or premium relative to the face value or as a premium over a treasury, but at the end it all should be converted to how much you have to pay today. In this case, it's how much you would pay today to get a set of future coupon and principal payments. What is Yield to Maturity? A bond is a contract entitling you to a certain set of predefined cash flows. If you take that set of cash flows and discount them using a single rate at all maturities such that the discounted value is equal to the price, the single rate you have identified is the YTM. Mathematically, this is the same as finding the IRR (internal rate of return) of some set of cash flows. In this case the cash flows are the coupons and principal repayment. Other bond concepts. Note that the other aspects of a bond, like maturity, coupon rate, and face value, are immutably written into the bond contract. All they do is define what payments the bond entitles the owner to. They don't say how much someone would pay today in order to be entitled to those payments. One can't know how much a future payment is worth without discounting. If you know the appropriate discount rate at every relevant maturity, you could calculate the fair price of a bond. That's the other direction. YTM looks at the market price and associated cash flows and imputes what single discount rate would make that price fair. What is YTM good for? Recall what I said about IRR above. Why would anyone want to know what discount rate equates the cash flows of a project to its cost? Because it's an easy way to summarize how profitable the project is expected to be. YTM is a quick way to summarize the yield one would get on a bond if they were to buy it today and hold to maturity. If one bond has a higher YTM than another, than heuristically we believe it pays out more and should be associated with greater risk if the market is working properly. It can be used to compare bonds or to look at how changes in bond prices are affecting expected yields. Ask yourself, how would you compare two different bonds with different maturities and coupon rates? Which one is riskier or more profitable? The simplest way to summarize this information is with the yield to maturity. YTM is used frequently enough that when you just say a bond's \"\"yield,\"\" people will assume you are talking about its yield to maturity. What is YTM not good for? One thing to be wary of is using YTM as a discount rate. It looks like a discount rate but it works for that bond and that bond only. In reality each individual coupon payment has a true discount rate, and the discount rate at each horizon is different from each other horizon. Those are true discount rates that can be applied to any cash flow of similar risk to get the right price. We can think of YTM as some kind of average of those discount rates that produces the correct price for that bond only. You should never use it for discounting something else.\"", "title": "" }, { "docid": "596511", "text": "How is that the federal reserve's fault? federal reserve's only tools are interest rates, loans, and buying/selling of bonds.

For a detailed explanation of the yield curve, see the linked answer that Joe and I wrote; in short, the yield curve is a plot of the yield on Treasury securities against their maturities. If short-term Treasuries are paying higher yields than long-term debt, the yield curve has a negative slope. There are a lot of factors that could cause the yield curve to become negatively sloped, or at least less steep, but in this case, oil prices and the effective federal funds rate may have played a significant role. I'll quote from the section of the linked answer that describes the effect of oil prices first: a rise in oil prices may increase expectations of short-term inflation, so investors demand higher interest rates on short-term debt. Because long-term inflation expectations are governed more by fundamental macroeconomic factors than short-term swings in commodity prices, long-term expectations may not rise nearly as much as short term expectations, which leads to a yield curve that is becoming less steep or even negatively sloped. As the graph shows, oil prices increased dramatically, so this increase may have increased expectations of short-term inflation expectations substantially. The other answer describes an easing of monetary policy, e.g. a decrease in the effective federal funds rate (FFR), as a factor that could increase the slope of the yield curve. However, a tightening of monetary policy, e.g. an increase in the FFR, could decrease the slope of the yield curve because a higher FFR leads investors to demand a higher rate of return on shorter-term securities. Longer-term Treasuries aren't as affected by short-term monetary policy, so when short-term yields increase more than long-term yields, the yield curve becomes less steep and/or negatively sloped. The second graph shows the effective federal funds rate for the period in question, and once again, the increase is significant. Finally, look at a graph of inflation for the relevant period. Intuitively, the steady increase in inflation from 1975 onward may have increased investors expectations of short-term inflation, therefore increasing short-term yields more than long-term yields (as described above and in the other answer). These reasons aren't set in stone, and just looking at graphs isn't a substitute for an actual analysis of the data, but logically, it seems plausible that the positive shock to oil prices, increases in the effective federal funds rate, and increases in inflation and expectations of inflation contributed at least partially to the inversion of the yield curve.

It does this primarily by buying government debt. The government spends more than it takes in, and so to come up with the deficit, it issues bonds. The Fed buys a certain amount of these bonds, and simply prints the money (or more realistically authorized the electronic transfer of $X to the Treasury) which the government then spends.

We find that the liver and ventral pancreas are specified at the same time and in the same general domain of cells. Using embryo tissue explantation experiments, we find that the default fate of the ventral foregut endoderm is to activate the pancreas gene program. FGF signalling from the cardiac mesoderm diverts this endoderm to express genes for liver instead of those for pancreas. No evidence was found to indicate that the cell type choice for pancreas or liver involves a selection for growth or viability.

Our studies show that ablation of BAF250a in early mouse embryos results in developmental arrest (about embryonic day 6.5) and absence of the mesodermal layer, indicating its critical role in early germ-layer formation. Moreover, BAF250a deficiency compromises ES cell pluripotency, severely inhibits self-renewal, and promotes differentiation into primitive endoderm-like cells under normal feeder-free culture conditions.

Furthermore, the pluripotency defects in BAF250a mutant ES cells appear to be cell lineage-specific.

However, if you need any of this money in the next few years, it would be a shame if it lost money in the short-term. How much do you need to finish grad school? Don't invest that money in the stock market, because you will need it over the next few years. Likewise, think about other expenses that are coming up. Will your car need to be replaced in the next couple of years? Will you have enough income to meet your living expenses while you are in grad school, or will you need some of this to money to help with that? Finally, it would be good to keep some extra as an emergency fund, so you can easily pay for any unexpected expenses that come up. If you can make it through grad school debt free, you will be much better off than if you invest all the money but take out student loans in the process.

There are several different things you can mean by this and I'm not sure which is accurate so I am going to address the first two that I thought of. If you are selling your investments because you need the money (emergency expenses, saved enough for a short term goal, whatever the reason) then this may not be the best solution for your savings. Investing in mutual funds, ETFs, stocks, 401k, IRA, etc are typically for longer term goals such as a goal that is 10+ years away (maybe buying a home, paying for college for your children, retirement, etc). If you are selling your investments because you believe that another investment is performing better and you want to get in on that one instead what I would suggest is leaving the money you have invested where it is and starting future investments in the new fund/ETF you are interested in. For example if you have $2000 invested in fund X and now you do some research and fund Q looks more appealing that is great, start investing in fund Q with your next deposit. Any research you do will be based on past results, there is nothing that guarantees that fund Q will continue doing better than the fund X you already have. Trying to time the market rarely ends well for the investor. I would encourage you to continue saving money a bit at a time just like you have been doing.

As an example, for an index fund, assets may get liquidated if the underlying index changes in composition, thus requiring the manager to sell some stocks and purchase others. Mutual funds are required to distribute most of their income that they generate in this way back to its shareholders; many often do this near the end of the calendar year. When you receive the distribution, the gains will be categorized as either short-term (the asset was held for less than one year) or long-term (vice versa). Based upon the holding period, the gain is taxed differently. Currently in the United States, long-term capital gains are only taxed at 15%, regardless of your income tax bracket (you only pay the capital gains tax, not the income tax). Short-term capital gains are treated as ordinary income, so you will pay your (probably higher) tax rate on any cash that you are given by your mutual fund. You may also be subject to capital gains taxes when you decide to sell your holdings in the fund. Any profit that you made based on the difference between your purchase and sale price is treated as a capital gain. Based upon the period of time that you held the mutual fund shares, it is categorized as a short- or long-term gain and is taxed accordingly in the tax year that you sell the shares. Dividends: Many companies pay dividends to their stockholders as a way of returning a portion of their profits to their collective owners. When you invest in a mutual fund that owns dividend-paying stocks, the fund is the \"\"owner\"\" that receives the dividend payments. As with capital gains, mutual funds will redistribute these dividends to you periodically, often quarterly or annually. The main difference with dividends is that they are always taxed as ordinary income, no matter how long you (or the fund) have held the asset.

The bond fund vehicle helps manage the credit risk, while the short terms help manage inflation and interest rate risk.

Corporate bonds are generally safer than stocks because, in bankruptcy, all your bondholders have to be paid in full before any equity-holders get a penny. Stocks are much more volatile, since they're essentially worth the value of their profits after paying all their debt, taxes, and other expenses. As far as stocks are concerned, they're not very good for the short term at all. One of the stabler stock funds would be something like the Vanguard Equity Income Fund, and it cautions: This fund is designed to provide investors with an above-average level of current income while offering exposure to the stock market. Since the fund typically invests in companies that are dedicated to consistently paying dividends, it may have a higher yield than other Vanguard stock mutual funds.

With that in mind, the main advantages of a mutual fund over an equivalent ETF are: From a long-term investor's point of view, the main disadvantage of mutual funds relative to ETFs is the minimum account sizes. Especially if the fund has multiple share classes (i.e., where better classes get lower expense ratios), you might have to have quite a lot of money invested in the fund in order to get the same expense ratio as the ETF. There are some other differences that matter to more active investors (e.g., intraday trading, options, etc.), but for a passive investor the ones above are the major ones. Apart from those mutual funds and ETFs are pretty similar. Personally, I prefer mutual funds because I'm at a point where the fund minimums aren't really an issue, and I don't want to deal with the more fiddly aspects of ETFs.

In fact, I would argue the question is not specific to mutual funds but can be applied to almost anyone who must make an investment decision: a mutual fund manager, hedge fund manager, or an individual investor. Even though money going into a company 401(k) retirement savings plan is typically automatically allocated to different funds as we have specified, this is generally not the case for other investment accounts. For example, I also have a Roth IRA in which I have some money from each paycheck direct deposited and it's up to me to decide whether to leave that money in cash or to invest it somewhere else. Every time you invest more money into a mutual fund, the fund manager has the same decision to make. There are two commonly used mutual fund figures that relate to your question: turnover rate, and cash reserves. Turnover rate measures the percent of a fund's portfolio that changes every year. For example, a turnover rate of 100% indicates that a fund replaces every asset it held at the beginning of the year with something else at the end of the year – funds with turnover rates greater than 100% average a holding period for a given asset of less than one year, and funds with turnover rates less than 100% average a holding period for a given asset of more than one year. Cash reserves simply measure the amount of money funds choose to keep as cash instead of investing in other assets. Another important distinction to make is between actively managed funds and passively managed funds. Passively managed funds are often referred to as \"\"index funds\"\" and have as their goal only to match the returns of a given index or some other benchmark. Actively managed funds on the other hand try to beat the market by exploiting so-called market inefficiencies; e.g. buying undervalued assets, selling overvalued assets, \"\"timing\"\" the market, etc. To answer your question for a specific fund, I would encourage you to look at the fund's prospectus. I take as one example of a passively managed fund the Vanguard 500 Index Fund (VFINX), a mutual fund that was created to track the S&P 500. In its prospectus, the fund states that, \"\"to track its target index as closely as possible, the Fund attempts to remain fully invested in stocks\"\". Furthermore, the prospectus states that \"\"the fund's daily cash balance may be invested in one or more Vanguard CMT Funds, which are very low-cost money market funds.\"\" Therefore, we would expect both this fund's turnover rate and cash reserves to be extremely low. When we look at its portfolio composition, we see this is true – it is currently at a 4.8% turnover rate and holds 0.0% in short term reserves. Therefore, we can assume this fund is regularly purchasing shares (similar to a dollar cost averaging strategy) instead of holding on to cash and purchasing shares together at a specific time. For actively managed funds, the picture will tend to look a little different. For example, if we look at the Magellan Fund's portfolio composition, we can see it has a turnover rate of 42%, and holds around .95% in cash/short term reserves. In this case, we can safely guess that trading activity may not be as regular as a passively managed fund, as an active manager attempts to time the market. You may find mutual funds that have much higher cash reserves – perhaps 10% or even more. Granted, it is impossible to know the exact trading strategy of a mutual fund, and for good reason – if we knew for example, that a fund purchases shares every day at 2:30PM in order to realign with the S&P 500, then sellers of S&P components could up the prices at that time to exploit the mutual fund's trade strategy. Large traders are constantly trying to find ways to conceal their actual trading activity in order to avoid these exact problems. Finally, I feel obligated to note that it is important to keep in mind that trade frequency is linked to transactions costs – in general, the more frequently an investment manager (whether it be you or a mutual fund manager) executes trades, the more that manager will lose in transactions costs.\"", "title": "" }, { "docid": "264820", "text": "\"An investment is sold when you sell that particular stock or fund.

If you are invested in a mutual fund, whether it's long or short term depends on when you buy and sell the fund. The fact that the fund managers are buying and selling behind your back doesn't affect this. (I don't know what taxes they have to pay, maybe you really are paying for it in the form of management fees or lower returns, but you don't explicitly pay the tax on these \"\"inner\"\" transactions.)

On the plus side, you'll have your $40,000 easily accessible to you to pay for moving, closing costs on your new house, etc. If you apply it to your mortgage, you are effectively saving the interest on the amount for the life of the loan. Let's say that the interest rate on your mortgage is 4%. If you were staying in the house long-term, this interest would be compounded, but since you are only going to be there for 1 year, this move will save you $1600 in interest this year, which means that when you sell the house and pay off this mortgage, you'll have $1600 extra in your pocket. You said that you don't like to dabble in stocks. I wouldn't recommend investing in individual stocks anyway. A stock mutual fund, however, is a great option for investing, but only as a long-term investment. You should be able to beat your 4% mortgage, but only over the long term. If you want to have the $40,000 available to you in a year, don't invest in a mutual fund now. I would lean toward option #2, applying the money to the mortgage. However, there are some other considerations: Do you have any other debts, maybe a car loan, student loan, or a credit card balance? If so, I would forget everything else and put everything toward one or more of these loans first.

One rule of thumb is that you have 3 to 6 months of expenses set aside in a safe, easily accessible account ready to go if something comes up. Are you saving for retirement? If you don't already have retirement savings in place and are adding to it regularly, some of this cash would be a great start to a Roth IRA or something like that, invested in a stock mutual fund. If you are already debt free except for this mortgage, you might want to do some of each: Keep $10,000 in a savings account for an emergency fund (if you don't already have an emergency fund), put $5,000 in a Roth IRA (if you aren't already contributing a satisfactory amount to a retirement account), and apply the rest toward your mortgage.", "title": "" }, { "docid": "403701", "text": "This is really an extended comment on the last paragraph of @BenMiller's answer. When (the manager of) a mutual fund sells securities that the fund holds for a profit, or receives dividends (stock dividends, bond interest, etc.), the fund has the option of paying taxes on that money (at corporate rates) and distributing the rest to shareholders in the fund, or passing on the entire amount (categorized as dividends, qualified dividends, net short-term capital gains, and net long-term capital gains) to the shareholders who then pay taxes on the money that they receive at their own respective tax rates. (If the net gains are negative, i.e. losses, they are not passed on to the shareholders. See the last paragraph below). A shareholder doesn't have to reinvest the distribution amount into the mutual fund: the option of receiving the money as cash always exists, as does the option of investing the distribution into a different mutual fund in the same family, e.g. invest the distributions from Vanguard's S&P 500 Index Fund into Vanguard's Total Bond Index Fund (and/or vice versa). This last can be done without needing a brokerage account, but doing it across fund families will require the money to transit through a brokerage account or a personal account. Such cross-transfers can be helpful in reducing the amounts of money being transferred in re-balancing asset allocations as is recommended be done once or twice a year. Those investing in load funds instead of no-load funds should keep in mind that several load funds waive the load for re-investment of distributions but some funds don't: the sales charge for the reinvestment is pure profit for the fund if the fund was purchased directly or passed on to the brokerage if the fund was purchased through a brokerage account. As Ben points out, a shareholder in a mutual fund must pay taxes (in the appropriate categories) on the distributions from the fund even though no actual cash has been received because the entire distribution has been reinvested. It is worth keeping in mind that when the mutual fund declares a distribution (say $1.22 a share), the Net Asset Value per share drops by the same amount (assuming no change in the prices of the securities that the fund holds) and the new shares issued are at this lower price. That is, there is no change in the value of the investment: if you had $10,000 in the fund the day before the distribution was declared, you still have $10,000 after the distribution is declared but you own more shares in the fund than you had previously. (In actuality, the new shares appear in your account a couple of days later, not immediately when the distribution is declared). In short, a distribution from a mutual fund that is re-invested leads to no change in your net assets, but does increase your tax liability. Ditto for a distribution that is taken as cash or re-invested elsewhere. As a final remark, net capital losses inside a mutual fund are not distributed to shareholders but are retained within the fund to be written off against future capital gains.

Similar rules may hold in some other countries as well. The shares in an open-ended (non-exchange-traded) mutual fund are not traded on stock exchanges and the \"\"market\"\" does not determine the share price the way it does for shares in companies as brokers make offers to buy and sell stock shares. The price of one share of the mutual fund (usually called Net Asset Value (NAV) per share) is usually calculated at the close of business, and is, as the name implies, the net worth of all the shares in companies that the fund owns plus cash on hand etc divided by the number of mutual fund shares outstanding. The NAV per share of a mutual fund might or might not increase in anticipation of the distribution to occur, but the NAV per share very definitely falls on the day that the distribution is declared. If you choose to re-invest your distribution in the same fund, then you will own more shares at a lower NAV per share but the total value of your investment will not change at all. If you had 100 shares currently priced at $10 and the fund declares a distribution of $2 per share, you will be reinvesting $200 to buy more shares but the fund will be selling you additional shares at $8 per share (and of course, the 100 shares you hold will be priced at $8 per share too. So, you will have 100 previous shares worth only $800 now + 25 new shares worth $200 for a total of 125 shares at $8 = $1000 total investment, just as before. If you take the distribution in cash, then you still hold the 100 shares but they are worth only $800 now, and the fund will send you the $200 as cash. Either way, there is no change in your net worth. However, (assuming that the fund is is not in a tax-advantaged account), that $200 is taxable income to you regardless of whether you reinvest it or take it as cash. The fund will tell you what part of that $200 is dividend income (as well as what part is Qualified Dividend income), what part is short-term capital gains, and what part is long-term capital gains; you declare the income in the appropriate categories on your tax return, and are taxed accordingly. So, what advantage is there in re-investing? Well, your basis in those shares has increased and so if and when you sell the shares, you will owe less tax. If you had bought the original 100 shares at $10 and sell the 125 shares a few years later at $11 and collect $1375, you owe (long-term capital gains) tax on just $1375-$1200 =$175 (which can also be calculated as $1 gain on each of the original 100 shares = $100 plus $3 gain on the 25 new shares = $175). In the past, some people would forget the intermediate transactions and think that they had invested $1000 initially and gotten $1375 back for a gain of $375 and pay taxes on $375 instead. This is less likely to occur now since mutual funds are now required to report more information on the sale to the shareseller than they used to in the past. So, should you buy shares in a mutual fund right now? Most mutual fund companies publish preliminary estimates in November and December of what distributions each fund will be making by the end of the year. They also usually advise against purchasing new shares during this period because one ends up \"\"buying a dividend\"\". If, for example, you bought those 100 shares at $10 on the Friday after Thanksgiving and the fund distributes that $2 per share on December 15, you still have $1000 on December 15, but now owe taxes on $200 that you would not have had to pay if you had postponed buying those shares till after the distribution was paid.

However, its role in coronary angiography is unclear. OBJECTIVE To determine whether oral acetylcysteine prevents acute deterioration in renal function in patients with moderate renal insufficiency who undergo elective coronary angiography. DESIGN AND SETTING Prospective, randomized, double-blind, placebo-controlled trial conducted from May 2000 to December 2001 at the Grantham Hospital at the University of Hong Kong. PARTICIPANTS Two hundred Chinese patients aged mean (SD) 68 (6.5) years with stable moderate renal insufficiency (creatinine clearance <60 mL/min [1.00 mL/s]) who were undergoing elective coronary angiography with or without intervention. INTERVENTION Participants were randomly assigned to receive oral acetylcysteine(600 mg twice per day; n = 102) or matching placebo tablets (n = 98) on the day before and the day of angiography. All patients received low-osmolality contrast agent. MAIN OUTCOME MEASURES Occurrence of more than a 25% increase in serum creatinine level within 48 hours after contrast administration; change in creatinine clearance and serum creatinine level. RESULTS Twelve control patients (12%) and 4 acetylcysteine patients (4%) developed a more than 25% increase in serum creatinine level within 48 hours after contrast administration (relative risk, 0.32; 95% confidence interval [CI], 0.10-0.96; P =.03). Serum creatinine was lower in the acetylcysteine group (1.22 mg/dL [107.8 micromol/L]; 95% CI, 1.11-1.33 mg/dL vs 1.38 mg/dL [122.9 micromol/L]; 95% CI, 1.27-1.49 mg/dL; P =.006) during the first 48 hours after angiography. Acetylcysteine treatment significantly increased creatinine clearance from 44.8 mL/min (0.75 mL/s) (95% CI, 42.7-47.6 mL/min) to 58.9 mL/min (0.98 mL/s) (95% CI, 55.6-62.3 mL/min) 2 days after the contrast administration (P<.001). The increase was not significant in the control group (from 42.1 to 44.1 mL/min [0.70 to 0.74 mL/s]; P =.15). The benefit of acetylcysteine was consistent among various patient subgroups and persistent for at least 7 days. There were no major treatment-related adverse events.

Although ACE inhibitor therapy usually improves renal blood flow (RBF) and sodium excretion rates in CHF and reduces the rate of progressive renal injury in chronic renal disease, its use can also be associated with a syndrome of “functional renal insufficiency” and/or hyperkalemia. This form of acute renal failure (ARF) most commonly develops shortly after initiation of ACE inhibitor therapy but can be observed after months or years of therapy, even in the absence of prior ill effects. ARF is most likely to occur when renal perfusion pressure cannot be sustained because of substantial decreases in mean arterial pressure (MAP) or when glomerular filtration rate (GFR) is highly angiotensin II (Ang II) dependent. Conditions that predict an adverse hemodynamic effect of ACE inhibitors in patients with CHF are preexisting hypotension and low cardiac filling pressures. The GFR is especially dependent on Ang II during extracellular fluid (ECF) volume depletion, high-grade bilateral renal artery stenosis, or stenosis of a dominant or single kidney, as in a renal transplant recipient. Understanding the pathophysiological mechanisms and the common risk factors for ACE inhibitor–induced functional ARF is critical, because preventive strategies for ARF exist, and if effectively used, they may permit use of these compounds in a less restricted fashion.

Systemic N-acetylcysteine (NAC) has been shown to restore glutamate homeostasis, reduce relapse to cocaine seeking, and depotentiate PFC-NAcore synapses. Here, we examine the effects of NAC applied directly to the NAcore on relapse and neurotransmission in PFC-NAcore synapses, as well as the involvement of the metabotropic glutamate receptors 2/3 (mGluR2/3) and 5 (mGluR5). METHODS Rats were trained to self-administer cocaine for 2 weeks and following extinction received either intra-accumbens NAC or systemic NAC 30 or 120 minutes, respectively, before inducing reinstatement with a conditioned cue or a combined cue and cocaine injection. We also recorded postsynaptic currents using in vitro whole cell recordings in acute slices and measured cystine and glutamate uptake in primary glial cultures. RESULTS NAC microinjection into the NAcore inhibited the reinstatement of cocaine seeking. In slices, a low concentration of NAC reduced the amplitude of evoked glutamatergic synaptic currents in the NAcore in an mGluR2/3-dependent manner, while high doses of NAC increased amplitude in an mGluR5-dependent manner. Both effects depended on NAC uptake through cysteine transporters and activity of the cysteine/glutamate exchanger. Finally, we showed that by blocking mGluR5 the inhibition of cocaine seeking by NAC was potentiated. CONCLUSIONS The effect of NAC on relapse to cocaine seeking depends on the balance between stimulating mGluR2/3 and mGluR5 in the NAcore, and the efficacy of NAC can be improved by simultaneously inhibiting mGluR5.", "title": "The effect of N-acetylcysteine in the nucleus accumbens on neurotransmission and relapse to cocaine." }, { "docid": "35724562", "text": "In adult patients with CKD, hypertension is linked to the development of left ventricular hypertrophy, but whether this association exists in children with CKD has not been determined conclusively.

METHODS The trial ran from 2001 to 2007.

A structure-function analysis of the BMP-Alk3-BMP receptor, type 2 (BMPR2) ligand-receptor complex, along with synthetic organic chemistry, led us to construct a library of small peptide agonists of BMP signaling that function through the Alk3 receptor. One such peptide agonist, THR-123, suppressed inflammation, apoptosis and the epithelial-to-mesenchymal transition program and reversed established fibrosis in five mouse models of acute and chronic renal injury. THR-123 acts specifically through Alk3 signaling, as mice with a targeted deletion for Alk3 in their tubular epithelium did not respond to therapy with THR-123. Combining THR-123 and the angiotensin-converting enzyme inhibitor captopril had an additive therapeutic benefit in controlling renal fibrosis. Our studies show that BMP signaling agonists constitute a new line of therapeutic agents with potential utility in the clinic to induce regeneration, repair and reverse established fibrosis.", "title": "Activin–like kinase–3 activity is important for kidney regeneration and reversal of fibrosis" }, { "docid": "3831884", "text": "Cancer cells have metabolic dependencies that distinguish them from their normal counterparts. Among these dependencies is an increased use of the amino acid glutamine to fuel anabolic processes. Indeed, the spectrum of glutamine-dependent tumours and the mechanisms whereby glutamine supports cancer metabolism remain areas of active investigation. Here we report the identification of a non-canonical pathway of glutamine use in human pancreatic ductal adenocarcinoma (PDAC) cells that is required for tumour growth. Whereas most cells use glutamate dehydrogenase (GLUD1) to convert glutamine-derived glutamate into α-ketoglutarate in the mitochondria to fuel the tricarboxylic acid cycle, PDAC relies on a distinct pathway in which glutamine-derived aspartate is transported into the cytoplasm where it can be converted into oxaloacetate by aspartate transaminase (GOT1). Subsequently, this oxaloacetate is converted into malate and then pyruvate, ostensibly increasing the NADPH/NADP(+) ratio which can potentially maintain the cellular redox state. Importantly, PDAC cells are strongly dependent on this series of reactions, as glutamine deprivation or genetic inhibition of any enzyme in this pathway leads to an increase in reactive oxygen species and a reduction in reduced glutathione. Moreover, knockdown of any component enzyme in this series of reactions also results in a pronounced suppression of PDAC growth in vitro and in vivo. Furthermore, we establish that the reprogramming of glutamine metabolism is mediated by oncogenic KRAS, the signature genetic alteration in PDAC, through the transcriptional upregulation and repression of key metabolic enzymes in this pathway. The essentiality of this pathway in PDAC and the fact that it is dispensable in normal cells may provide novel therapeutic approaches to treat these refractory tumours.", "title": "Glutamine supports pancreatic cancer growth through a Kras-regulated metabolic pathway" }, { "docid": "14121786", "text": "BACKGROUND Epidemiologic analysis of family data on blood pressure (BP) is often compromised by the effects of antihypertensive medications. A review of numerous clinical trials that investigated the effects of BP-lowering medications is summarized here. METHODS Published clinical trials, including 137 clinical trials with monodrug therapies and 28 clinical trials of combination drug therapies with a total of 11,739 participants, were reviewed from PubMed. Six major classes/groups of antihypertensive medications were categorized by ethnicity, including angiotensin-converting enzyme (ACE) inhibitors, alpha1-blockers, cardioselective beta-blockers (beta1-blockers), calcium channel blockers, thiazide and thiazide-like diuretics, and loop diuretics. RESULTS Using sitting or supine BP, for ethnic groups combined, monodrug therapy with ACE inhibitors showed a weighted average effect of lowering the systolic and diastolic BP by 12.5/9.5 mm Hg; alpha1-blockers by 15.5/11.7 mm Hg; beta1-blockers by 14.8/12.2 mm Hg; calcium channel blockers by 15.3/10.5 mm Hg; thiazide diuretics by 15.3/9.8 mm Hg; and loop diuretics by 15.8/8.2 mm Hg. However, ACE inhibitors, alpha1-blockers, and beta1-blockers were less effective in African Americans than in non-African Americans, whereas calcium channel blockers, thiazide diuretics, and loop diuretics were more effective in African Americans than in non-African Americans. For two-drug combination therapy with ethnic groups combined, the BP-lowering effect of the second medication, when compared to its effect as monodrug therapy, was 84% and 65% for systolic and diastolic BP, respectively.

Their activity requires the maintenance of an adequate intracellular NAD(+) concentration through the combined action of NAD(+) biosynthesis and salvage pathways. Nicotinamide (NAM) is a key NAD(+) precursor that is also a byproduct and feedback inhibitor of the deacetylation reaction. In Saccharomyces cerevisiae, the nicotinamidase Pnc1 converts NAM to nicotinic acid (NA), which is then used as a substrate by the NAD(+) salvage pathway enzyme NA phosphoribosyltransferase (Npt1). Isonicotinamide (INAM) is an isostere of NAM that stimulates yeast Sir2 deacetylase activity in vitro by alleviating the NAM inhibition. In this study, we determined that INAM stimulates Sir2 through an additional mechanism in vivo, which involves elevation of the intracellular NAD(+) concentration. INAM enhanced normal silencing at the rDNA locus but only partially suppressed the silencing defects of an npt1Δ mutant. Yeast cells grown in media lacking NA had a short replicative life span, which was extended by INAM in a SIR2-dependent manner and correlated with increased NAD(+). The INAM-induced increase in NAD(+) was strongly dependent on Pnc1 and Npt1, suggesting that INAM increases flux through the NAD(+) salvage pathway. Part of this effect was mediated by the NR salvage pathways, which generate NAM as a product and require Pnc1 to produce NAD(+).

Whereas several proteins are known to regulate chromatin marks associated with the distinct epigenetic states of cells before and after reprogramming, the role of specific chromatin-modifying enzymes in reprogramming remains to be determined. To address how chromatin-modifying proteins influence reprogramming, we used short hairpin RNAs (shRNAs) to target genes in DNA and histone methylation pathways, and identified positive and negative modulators of iPSC generation. Whereas inhibition of the core components of the polycomb repressive complex 1 and 2, including the histone 3 lysine 27 methyltransferase EZH2, reduced reprogramming efficiency, suppression of SUV39H1, YY1 and DOT1L enhanced reprogramming. Specifically, inhibition of the H3K79 histone methyltransferase DOT1L by shRNA or a small molecule accelerated reprogramming, significantly increased the yield of iPSC colonies, and substituted for KLF4 and c-Myc (also known as MYC). Inhibition of DOT1L early in the reprogramming process is associated with a marked increase in two alternative factors, NANOG and LIN28, which play essential functional roles in the enhancement of reprogramming. Genome-wide analysis of H3K79me2 distribution revealed that fibroblast-specific genes associated with the epithelial to mesenchymal transition lose H3K79me2 in the initial phases of reprogramming. DOT1L inhibition facilitates the loss of this mark from genes that are fated to be repressed in the pluripotent state.

As the prevalence of type 2 diabetes is rapidly increasing, prevention of the disease should be considered as a key objective in the near future. Besides lifestyle changes, various pharmacological treatments have proven their efficacy in placebo-controlled clinical trials, including antidiabetic drugs such as metformin, acarbose and troglitazone, or antiobesity agents such as orlistat. Arterial hypertension, a clinical entity in which insulin resistance is common, is strongly associated with type 2 diabetes and may precede the disease by several years. While antihypertensive agents such as diuretics or β-adrenoceptor antagonists may worsen insulin resistance and impair glucose tolerance, newer antihypertensive agents exert neutral or even slightly positive metabolic effects. Numerous clinical trials have investigated the effects of ACE inhibitors or angiotensin II receptor antagonists (ARAs) on insulin sensitivity in hypertensive patients, with or without diabetes, with no consistent results. Almost half of the studies with ACE inhibitors in hypertensive nondiabetic individuals demonstrated a slight but significant increase in insulin sensitivity as assessed by insulin-stimulated glucose disposal during a euglycaemic hyperinsulinaemic clamp, while the other half failed to reveal any significant change. The effects of ARAs on insulin sensitivity are neutral in most studies. Mechanisms of improvement of glucose tolerance and insulin sensitivity through the inhibition of the renin-angiotensin system (RAS) are complex. They may include improvement of blood flow and microcirculation in skeletal muscles and, thereby, enhancement of insulin and glucose delivery to the insulin-sensitive tissues, facilitating insulin signalling at the cellular level and improvement of insulin secretion by the β cells. Six recent large-scale clinical studies reported a remarkably consistent reduction in the incidence of type 2 diabetes in hypertensive patients treated with either ACE inhibitors or ARAs for 3–6 years, compared with a thiazide diuretic, β-adrenoceptor antagonist, the calcium channel antagonist amlodipine or even placebo. The relative risk reduction averaged 14% (p = 0.034) in the CAPPP (Captopril Prevention Project) with captopril compared with a thiazide or β1-adrenoceptor antagonist, 34% (p < 0.001) in the HOPE (Heart Outcomes Prevention Evaluation) study with ramipril compared with placebo, 30% (p < 0.001) in the ALLHAT (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial) with lisinopril compared with chlortalidone, 25% (p < 0.001) in the LIFE (Losartan Intervention For Endpoint reduction in hypertension study) with losartan compared with atenolol, and 25% (p = 0.09) in the SCOPE (Study on Cognition and Prognosis in the Elderly) with candesartan cilexetil compared with placebo, and 23% (p < 0.0001) in the VALUE (Valsartan Antihypertensive Long-term Use Evaluation) trial with valsartan compared with amlodipine. All these studies considered the development of diabetes as a secondary endpoint, except the HOPE trial where it was a post hoc analysis. These encouraging observations led to the initiation of two large, prospective, placebo-controlled randomised clinical trials whose primary outcome is the prevention of type 2 diabetes: the DREAM (Diabetes REduction Approaches with ramipril and rosiglitazone Medications) trial with the ACE inhibitor ramipril and the NAVIGATOR (Nateglinide And Valsartan in Impaired Glucose Tolerance Outcomes Research) trial with the ARA valsartan. Finally, ONTARGET (ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial) will also investigate as a secondary endpoint whether it is possible to prevent the development of type 2 diabetes by blocking the RAS with either an ACE inhibitor or an ARA or a combination of both. Thus, the recent consistent observations of a 14–34% reduction of the development of diabetes in hypertensive patients receiving ACE inhibitors or ARAs are exciting.

Previous data indicates that Tregs may affect the microenvironment redox state. Given the inherent redox sensitivity of T cells, we tested the hypothesis that oxidants may mediate the direct suppression of Teffs by Tregs. METHODOLOGY/PRINCIPAL FINDINGS Tregs and Teffs were isolated from the spleens of wild type (WT) C57BL/6 mice or Ncf1(p47phox)-deficient C57BL/6 mice which lack NADPH oxidase function. Teffs were labeled with CFSE and co-cultured with unlabeled Tregs at varying Treg:Teff ratios in the presence of anti-CD3/CD28 coated beads for 3 days in suppression assays. Treg-mediated suppression was quantified by flow cytometric analysis of CFSE dilution in Teffs. The presence of the antioxidants n-acetylcysteine (NAC) or 2-mercaptoethanol or inhibitors of NADPH oxidase (diphenyleneiodonium and VAS-2870) resulted in reduced WT Treg-mediated suppression. The observed suppression was in part dependent upon TGFβ as it was partially blocked with neutralizing antibodies. The suppression of Teff proliferation induced by exogenous TGFβ treatment could be overcome with NAC. Ncf1-deficient Teff were slightly but significantly less sensitive than WT Teff to suppression by exogenous TGFβ. Ncf1-deficient Tregs suppressed Ncf1-deficient Teff very poorly compared to wild type controls. There was partial but incomplete reconstitution of suppression in assays with WT Tregs and Ncf1-deficient Teff.

PARTICIPANTS Patients with diabetes or coronary heart disease, or both, and blood pressure above 140/90 mm Hg, low density lipoprotein concentration >3.37 mmol/L, or glycated haemoglobin 8.5% or higher, and PHQ-9 depression scores of ≥ 10. INTERVENTION A 12 month intervention to improve depression, glycaemic control, blood pressure, and lipid control by integrating a \"treat to target\" programme for diabetes and risk factors for coronary heart disease with collaborative care for depression. The intervention combined self management support, monitoring of disease control, and pharmacotherapy to control depression, hyperglycaemia, hypertension, and hyperlipidaemia. MAIN OUTCOME MEASURES Social role disability (Sheehan disability scale), global quality of life rating, and World Health Organization disability assessment schedule (WHODAS-2) scales to measure disabilities in activities of daily living (mobility, self care, household maintenance). RESULTS Of 214 patients enrolled (106 intervention and 108 usual care), disability and quality of life measures were obtained for 97 intervention patients at six months (92%) and 92 at 12 months (87%), and for 96 usual care patients at six months (89%) and 92 at 12 months (85%).

DESIGN AND METHODS Using questionnaire data from 906,578 responders to the English 2012 General Practice Patient Survey, we describe the primary care experiences of patients with long-term conditions, including 583,143 patients who reported one or more long-term conditions. We employed mixed effect logistic regressions to analyse data on six items covering three care domains (access, continuity and communication) and a single item on overall primary care experience. We controlled for sociodemographic characteristics, and for general practice using a random effect, and further, controlled for, and explored the importance of, health-related quality of life measured using the EuroQoL (EQ-5D) scale. RESULTS Most patients with long-term conditions report a positive experience of care at their general practice (after adjusting for sociodemographic characteristics and general practice, range 74.0-93.1% reporting positive experience of care across seven questions) with only modest variation by type of condition. For all three domains of patient experience, an increasing number of comorbid conditions is associated with a reducing percentage of patients reporting a positive experience of care. For example, compared with respondents with no long-term condition, the OR for reporting a positive experience is 0.83 (95% CI 0.80 to 0.87) for respondents with four or more long-term conditions.

OBJECTIVE To describe the baseline characteristics of patients with a diagnosis of intervertebral disc herniation who had different treatment preferences and the relationship of specific expectations with those preferences. SUMMARY OF BACKGROUND DATA Data were gathered from the observational cohort of the Spine Patient Outcomes Research Trial (SPORT). Patients in the observational cohort met eligibility requirements identical to those of the randomized cohort, but declined randomization, receiving instead the treatment of their choice. METHODS Baseline preference and expectation data were acquired at the time of enrollment of the patient, before exposure to the informed consent process. Univariate analyses were performed using a t test for continuous variables and chi for categorical variables. Multivariate analyses were also performed with ANCOVA for continuous variables and logistic regression for categorical variables. Multiple logistic regression models were developed in a forward stepwise fashion using blocks of variables. RESULTS More patients preferred operative care: 67% preferred surgery, 28% preferred nonoperative treatment, and 6% were unsure; 53% of those preferring surgery stated a definite preference, whereas only 18% of those preferring nonoperative care had a definite preference. Patients preferring surgery were younger, had lower levels of education, and higher levels of unemployment/disability. This group also reported higher pain, worse physical and mental functioning, more back pain related disability, a longer duration of symptoms, and more opiate use. Gender, race, comorbidities, and use of other therapies did not differ significantly across preference groups.

Using this approach, it is possible to refine gene regions such as exon boundaries, novel genes, gene boundaries, frame shifts, reverse strands, translated UTRs, and novel splice junctions. One of the challenges of proteogenomics is how best to (1) tackle assigning confidence to any resulting annotation and (2) apply these gene model refinements, either through manual annotation or through an automated process via training gene prediction tools. This is not a straightforward process, as many gene prediction tools have their defined suitability for niche genomes (either eukaryotic or prokaryotic) trained on and refined with model organisms such as Arabidopsis thaliana and Escherichia coli, and varying degrees of features that can leverage the use of external evidence.

DESIGN We conducted a cohort study to examine the association between a variety of chronic comorbidities and risk of FN in patients diagnosed with six types of cancer (non-Hodgkin lymphoma and breast, colorectal, lung, ovary, and gastric cancer) from 2000 to 2009 who were treated with chemotherapy at Kaiser Permanente Southern California, a large managed care organization. We excluded those patients who received primary prophylactic granulocyte colony-stimulating factor. History of comorbidities and FN events were identified using electronic medical records. Cox models adjusting for propensity score, stratified by cancer type, were used to determine the association between comorbid conditions and FN. Models that additionally adjusted for cancer stage, baseline neutrophil count, chemotherapy regimen, and dose reduction were also evaluated. RESULTS A total of 19 160 patients with mean age of 60 years were included; 963 (5.0%) developed FN in the first chemotherapy cycle.

However, it is becoming recognized that frailty may be a distinct clinical syndrome with a biological basis. The frailty process appears to be a transitional state in the dynamic progression from robustness to functional decline. During this process, total physiological reserves decrease and become less likely to be sufficient for the maintenance and repair of the ageing body. Central to the clinical concept of frailty is that no single altered system alone defines it, but that multiple systems are involved. Clinical consensus regarding the phenotype which constitutes frailty, drawing upon the opinions of numerous authors, shows the characteristics to include wasting (loss of both muscle mass and strength and weight loss), loss of endurance, decreased balance and mobility, slowed performance, relative inactivity and, potentially, decreased cognitive function. Frailty is a distinct entity easily recognized by clinicians, with multiple manifestations and with no single symptom being sufficient or essential in its presentation. Manifestations include appearance (consistent or not with age), nutritional status (thin, weight loss), subjective health rating (health perception), performance (cognition, fatigue), sensory/physical impairments (vision, hearing, strength) and current care (medication, hospital). Although the early stages of the frailty process may be clinically silent, when depleted reserves reach an aggregate threshold leading to serious vulnerability, the syndrome may become detectable by looking at clinical, functional, behavioral and biological markers. Thus, a better understanding of these clinical changes and their underlying mechanisms, beginning in the pre-frail state, may confirm the impression held by many geriatricians that increasing frailty is distinguishable from ageing and in consequence is potentially reversible.

Here we report that myeloid-derived suppressor cells (MDSC), which are classically linked to immunosuppression, inflammation, and cancer, were markedly expanded in the bone marrow of MDS patients and played a pathogenetic role in the development of ineffective hematopoiesis. These clonally distinct MDSC overproduce hematopoietic suppressive cytokines and function as potent apoptotic effectors targeting autologous hematopoietic progenitors. Using multiple transfected cell models, we found that MDSC expansion is driven by the interaction of the proinflammatory molecule S100A9 with CD33. These 2 proteins formed a functional ligand/receptor pair that recruited components to CD33’s immunoreceptor tyrosine-based inhibition motif (ITIM), inducing secretion of the suppressive cytokines IL-10 and TGF-β by immature myeloid cells. S100A9 transgenic mice displayed bone marrow accumulation of MDSC accompanied by development of progressive multilineage cytopenias and cytological dysplasia. Importantly, early forced maturation of MDSC by either all-trans-retinoic acid treatment or active immunoreceptor tyrosine-based activation motif–bearing (ITAM-bearing) adapter protein (DAP12) interruption of CD33 signaling rescued the hematologic phenotype.

METHODS Survivors and their physicians were surveyed to evaluate for expectations regarding physician participation in primary cancer follow-up, screening for other cancers, general preventive health, and management of comorbidities. RESULTS Of 992 eligible survivors and 607 physicians surveyed, 535 (54%) and 378 (62%) were assessable, respectively. Among physician respondents, 255 (67%) were PCPs and 123 (33%) were oncologists. Comparing patients with their oncologists, expectations were highly discrepant for screening for cancers other than the index one (agreement rate, 29%), with patients anticipating significantly more oncologist involvement. Between patients and their PCPs, expectations were most incongruent for primary cancer follow-up (agreement rate, 35%), with PCPs indicating they should contribute a much greater part to this aspect of care. Expectations between patients and their PCPs were generally more concordant than between patients and their oncologists.

MAIN OUTCOME MEASURES Prevalence and correlates of MDD using the World Health Organization's (WHO) Composite International Diagnostic Interview (CIDI), 12-month severity with the Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR), the Sheehan Disability Scale (SDS), and the WHO disability assessment scale (WHO-DAS). Clinical reinterviews used the Structured Clinical Interview for DSM-IV. RESULTS The prevalence of CIDI MDD for lifetime was 16.2% (95% confidence interval [CI], 15.1-17.3) (32.6-35.1 million US adults) and for 12-month was 6.6% (95% CI, 5.9-7.3) (13.1-14.2 million US adults). Virtually all CIDI 12-month cases were independently classified as clinically significant using the QIDS-SR, with 10.4% mild, 38.6% moderate, 38.0% severe, and 12.9% very severe. Mean episode duration was 16 weeks (95% CI, 15.1-17.3). Role impairment as measured by SDS was substantial as indicated by 59.3% of 12-month cases with severe or very severe role impairment. Most lifetime (72.1%) and 12-month (78.5%) cases had comorbid CIDI/DSM-IV disorders, with MDD only rarely primary. Although 51.6% (95% CI, 46.1-57.2) of 12-month cases received health care treatment for MDD, treatment was adequate in only 41.9% (95% CI, 35.9-47.9) of these cases, resulting in 21.7% (95% CI, 18.1-25.2) of 12-month MDD being adequately treated. Sociodemographic correlates of treatment were far less numerous than those of prevalence. CONCLUSIONS Major depressive disorder is a common disorder, widely distributed in the population, and usually associated with substantial symptom severity and role impairment. While the recent increase in treatment is encouraging, inadequate treatment is a serious concern. Emphasis on screening and expansion of treatment needs to be accompanied by a parallel emphasis on treatment quality improvement.", "title": "The epidemiology of major depressive disorder: results from the National Comorbidity Survey Replication (NCS-R)." }, { "docid": "22688699", "text": "OBJECT Awake craniotomy was performed as the standard surgical approach to supratentorial intraaxial tumors, regardless of the involvement of eloquent cortex, in a prospective trial of 200 patients surgically treated by the same surgeon at a single institution. METHODS Patient presentations, comorbid conditions, tumor locations, and the histological characteristics of lesions were recorded. Brain mapping was possible in 195 (97.5%) of 200 patients. The total number of patients sustaining complications was 33 for an overall complication rate of 16.5%. There were two deaths in this series, for a mortality rate of 1%. New postoperative neurological deficits were seen in 13% of the patients, but these were permanent in only 4.5% of them. Complication rates were higher in patients who had gliomas or preoperative neurological deficits and in those who had undergone prior radiation therapy or surgery. No patient who entered the operating room neurologically intact sustained a permanent neurological deficit postoperatively. Of the most recent 50 patients treated, three (6%) required a stay in the intensive care unit, and the median total hospital stay was 1 day. CONCLUSIONS Use of awake craniotomy can result in a considerable reduction in resource utilization without compromising patient care by minimizing intensive care time and total hospital stay. Awake craniotomy is a practical and effective standard surgical approach to supratentorial tumors with a low complication rate, and provides an excellent alternative to craniotomy performed with the patient in the state of general anesthesia because it allows the opportunity for brain mapping and avoids general anesthesia.", "title": "Awake craniotomy with brain mapping as the routine surgical approach to treating patients with supratentorial intraaxial tumors: a prospective trial of 200 cases." }, { "docid": "24318630", "text": "Since 2008 the World Health Organization (WHO), through its mental health Gap Action Programme, has attempted to revitalize efforts to integrate mental health into non-specialized (e.g. primary) healthcare.

OBJECTIVES To assess the relationship between health literacy and health-related quality of life (HRQoL) in patients with ischaemic heart disease (IHD), and to investigate the role of sociodemographic and clinical variables as possible confounders. METHODS Cross-sectional study of patients with IHD recruited from a stratified sample of general practices in two Australian states (Queensland and South Australia) between 2007 and 2009. Health literacy was measured using a validated questionnaire and classified as inadequate, marginal, or adequate. Physical and mental components of HRQoL were assessed using the Medical Outcomes Study Short Form (SF12) questionnaire. Analyses were adjusted for confounders (sociodemographic variables, clinical history of IHD, number of CVD comorbidities, and CVD risk factors) using multiple linear regression. RESULTS A total sample of 587 patients with IHD (mean age 72.0±8.4 years) was evaluated: 76.8% males, 84.2% retired or pensioner, and 51.4% with up to secondary educational level. Health literacy showed a mean of 39.6±6.7 points, with 14.3% (95%CI 11.8-17.3) classified as inadequate. Scores of the physical component of HRQoL were 39.6 (95%CI 37.1-42.1), 42.1 (95%CI 40.8-43.3) and 44.8 (95%CI 43.3-46.2) for inadequate, marginal, and adequate health literacy, respectively (p-value for trend = 0.001). This association persisted after adjustment for confounders. Health literacy was not associated with the mental component of HRQoL (p-value = 0.482).

Despite this recommendation, SDM is not yet integrated in sciatica care. Existing literature concerning barriers and facilitators to SDM implementation mainly focuses on one discipline only, whereas multidisciplinary care may involve other barriers and facilitators, or make these more complex for both professionals and patients. Therefore, this qualitative study aims to identify barriers and facilitators perceived by patients and professionals for SDM implementation in multidisciplinary sciatica care. METHODS We conducted 40 semi-structured interviews with professionals involved in sciatica care (general practitioners, physical therapists, neurologists, neurosurgeons, and orthopedic surgeons) and three focus groups among patients (six to eight per group). The interviews and focus groups were audiotaped and transcribed in full. Reported barriers and facilitators were classified according to the framework of Grol and Wensing. The software package Atlas.ti 7.0 was used for analysis. RESULTS Professionals reported 53 barriers and 5 facilitators, and patients 35 barriers and 18 facilitators for SDM in sciatica care. Professionals perceived most barriers at the level of the organizational context, and facilitators at the level of the individual professional. Patients reported most barriers and facilitators at the level of the individual professional. Several barriers and facilitators correspond with barriers and facilitators found in the literature (e.g., lack of time, motivation) but also new barriers and facilitators were identified. Many of these new barriers mentioned by both professionals and patients were related to the multidisciplinary setting, such as lack of visibility, lack of trust in expertise of other disciplines, and lack of communication between disciplines. CONCLUSIONS This study identified barriers and facilitators for SDM in the multidisciplinary sciatica setting, by both professionals and patients. It is clear that more barriers than facilitators are perceived for implementation of SDM in sciatica care. Newly identified barriers and facilitators are related to the multidisciplinary care setting. Therefore, an effective implementation strategy of SDM in a multidisciplinary setting such as in sciatica care should focus on these barriers and facilitators.", "title": "Barriers and facilitators to implement shared decision making in multidisciplinary sciatica care: a qualitative study" }, { "docid": "44830890", "text": "OBJECTIVE To investigate the frequency of depressive and anxiety disorders in patients with chronic daily headache. BACKGROUND There is a lack of data in the literature on the extent of psychiatric comorbidity in patients with different subtypes of chronic daily headache. METHODS We recruited consecutive patients with chronic daily headache seen in a headache clinic from November 1998 to December 1999. The subtypes of chronic daily headache were classified according to the criteria proposed by Silberstein et al. A psychiatrist evaluated the patients according to the structured Mini-International Neuropsychiatric Interview to assess the comorbidity of depressive and anxiety disorders. RESULTS Two hundred sixty-one patients with chronic daily headache were recruited. The mean age was 46 years, and 80% were women. Transformed migraine was diagnosed in 152 patients (58%) and chronic tension-type headache in 92 patients (35%). Seventy-eight percent of patients with transformed migraine had psychiatric comorbidity, including major depression (57%), dysthymia (11%), panic disorder (30%), and generalized anxiety disorder (8%). Sixty-four percent of patients with chronic tension-type headache had psychiatric diagnoses, including major depression (51%), dysthymia (8%), panic disorder (22%), and generalized anxiety disorder (1%). The frequency of anxiety disorders was significantly higher in patients with transformed migraine after controlling for age and sex (P =.02).

Yet the cellular machinery that links nutrient sensing to inflammation remains incompletely characterized. The protein deacetylase sirtuin-1 (SirT1) is activated by energy depletion and plays a critical role in the mammalian response to fasting. More recently it has been implicated in the repression of inflammation. SirT1 mRNA and protein expression are suppressed in obese rodent and human white adipose tissue, while experimental reduction of SirT1 in adipocytes and macrophages causes low-grade inflammation that mimics that observed in obesity. Thus suppression of SirT1 during overnutrition may be critical to the development of obesity-associated inflammation. This effect is attributable to multiple actions of SirT1, including direct deacetylation of NFκB and chromatin remodeling at inflammatory gene promoters. In this work, we report that SirT1 is also suppressed by diet-induced obesity in macrophages, which are key contributors to the ontogeny of metabolic inflammation.

Methods and Findings We reviewed all studies that compared teaching versus nonteaching healthcare structures for mortality or any other patient outcome, regardless of health condition. Studies were retrieved from PubMed, contact with experts, and literature cross-referencing. Data were extracted on setting, patients, data sources, author affiliations, definition of compared groups, types of diagnoses considered, adjusting covariates, and estimates of effect for mortality and for each other outcome. Overall, 132 eligible studies were identified, including 93 on mortality and 61 on other eligible outcomes (22 addressed both). Synthesis of the available adjusted estimates on mortality yielded a summary relative risk of 0.96 (95% confidence interval [CI], 0.93–1.00) for teaching versus nonteaching healthcare structures and 1.04 (95% CI, 0.99–1.10) for minor teaching versus nonteaching ones.

Similarly, the USPSTF notes that policy and coverage decisions involve considerations in addition to the evidence of clinical benefits and harms. Summary of Recommendation and Evidence The USPSTF recommends annual screening for lung cancer with low-dose computed tomography (LDCT) in adults aged 55 to 80 years who have a 30 pack-year smoking history and currently smoke or have quit within the past 15 years. Screening should be discontinued once a person has not smoked for 15 years or develops a health problem that substantially limits life expectancy or the ability or willingness to have curative lung surgery.

What the USPSTF Grades Mean and Suggestions for Practice Appendix Table 2. USPSTF Levels of Certainty Regarding Net Benefit Supplement. Consumer Fact Sheet. Rationale Importance Lung cancer is the third most common cancer and the leading cause of cancer-related death in the United States (1). The most important risk factor for lung cancer is smoking, which results in approximately 85% of all U.S. lung cancer cases (2). Although the prevalence of smoking has decreased, approximately 37% of U.S. adults are current or former smokers (2). The incidence of lung cancer increases with age and occurs most commonly in persons aged 55 years or older. Increasing age and cumulative exposure to tobacco smoke are the 2 most common risk factors for lung cancer. Lung cancer has a poor prognosis, and nearly 90% of persons with lung cancer die of the disease. However, early-stage nonsmall cell lung cancer (NSCLC) has a better prognosis and can be treated with surgical resection. Detection Most lung cancer cases are NSCLC, and most screening programs focus on the detection and treatment of early-stage NSCLC. Although chest radiography and sputum cytologic evaluation have been used to screen for lung cancer, LDCT has greater sensitivity for detecting early-stage cancer (3). Benefits of Detection and Early Treatment Although lung cancer screening is not an alternative to smoking cessation, the USPSTF found adequate evidence that annual screening for lung cancer with LDCT in a defined population of high-risk persons can prevent a substantial number of lung cancerrelated deaths. Direct evidence from a large, well-conducted, randomized, controlled trial (RCT) provides moderate certainty of the benefit of lung cancer screening with LDCT in this population (4). The magnitude of benefit to the person depends on that person's risk for lung cancer because those who are at highest risk are most likely to benefit. Screening cannot prevent most lung cancerrelated deaths, and smoking cessation remains essential. Harms of Detection and Early Intervention and Treatment The harms associated with LDCT screening include false-negative and false-positive results, incidental findings, overdiagnosis, and radiation exposure. False-positive LDCT results occur in a substantial proportion of screened persons; 95% of all positive results do not lead to a diagnosis of cancer. In a high-quality screening program, further imaging can resolve most false-positive results; however, some patients may require invasive procedures. The USPSTF found insufficient evidence on the harms associated with incidental findings. Overdiagnosis of lung cancer occurs, but its precise magnitude is uncertain. A modeling study performed for the USPSTF estimated that 10% to 12% of screen-detected cancer cases are overdiagnosedthat is, they would not have been detected in the patient's lifetime without screening. Radiation harms, including cancer resulting from cumulative exposure to radiation, vary depending on the age at the start of screening; the number of scans received; and the person's exposure to other sources of radiation, particularly other medical imaging. USPSTF Assessment The USPSTF concludes with moderate certainty that annual screening for lung cancer with LDCT is of moderate net benefit in asymptomatic persons who are at high risk for lung cancer based on age, total cumulative exposure to tobacco smoke, and years since quitting smoking. The moderate net benefit of screening depends on limiting screening to persons who are at high risk, the accuracy of image interpretation being similar to that found in the NLST (National Lung Screening Trial), and the resolution of most false-positive results without invasive procedures (4). Clinical Considerations Patient Population Under Consideration The risk for lung cancer increases with age and cumulative exposure to tobacco smoke and decreases with time since quitting smoking. The best evidence for the benefit of screening comes from the NLST, which enrolled adults aged 55 to 74 years who had at least a 30 pack-year smoking history and were current smokers or had quit within the past 15 years. As with all screening trials, the NLST tested a specific intervention over a finite period. Because initial eligibility extended through age 74 years and participants received 3 annual screening computed tomographic scans, the oldest participants in the trial were aged 77 years. The USPSTF used modeling studies to predict the benefits and harms of screening programs that use different screening intervals, age ranges, smoking histories, and times since quitting. A program that annually screens adults aged 55 to 80 years who have a 30 pack-year smoking history and currently smoke or have quit within the past 15 years is projected to have a reasonable balance of benefits and harms. The model assumes that persons who achieve 15 years of smoking cessation during the screening program discontinue screening. This model predicts the outcomes of continuing the screening program used in the NLST through age 80 years. Screening may not be appropriate for patients with substantial comorbid conditions, particularly those at the upper end of the screening age range. The NLST excluded persons who were unlikely to complete curative lung cancer surgery and those with medical conditions that posed a substantial risk for death during the 8-year trial. The baseline characteristics of the NLST showed a relatively healthy sample, and fewer than 10% of enrolled participants were older than 70 years (5). Persons with serious comorbid conditions may experience net harm, no net benefit, or at least substantially less net benefit. Similarly, persons who are unwilling to have curative lung surgery are unlikely to benefit from a screening program. Assessment of Risk Age, total exposure to tobacco smoke, and years since quitting smoking are important risk factors for lung cancer and were used to determine eligibility in the NLST. Other risk factors include specific occupational exposures, radon exposure, family history, and history of pulmonary fibrosis or chronic obstructive lung disease. The incidence of lung cancer is relatively low in persons younger than 50 years but increases with age, especially after age 60 years. In current and former smokers, age-specific incidence rates increase with age and cumulative exposure to tobacco smoke. Smoking cessation substantially reduces a person's risk for developing and dying of lung cancer. Among persons enrolled in the NLST, those who were at highest risk because of additional risk factors or a greater cumulative exposure to tobacco smoke experienced most of the benefit (6). A validated multivariate model showed that persons in the highest 60% of risk accounted for 88% of all deaths preventable by screening. Screening Tests Low-dose computed tomography has shown high sensitivity and acceptable specificity for the detection of lung cancer in high-risk persons. Chest radiography and sputum cytologic evaluation have not shown adequate sensitivity or specificity as screening tests. Therefore, LDCT is currently the only recommended screening test for lung cancer. Treatment Surgical resection is the current standard of care for localized NSCLC. This type of cancer is treated with surgical resection when possible and also with radiation and chemotherapy. Annual LDCT screening may not be useful for patients with life-limiting comorbid conditions or poor functional status who may not be candidates for surgery. Other Approaches to Prevention Smoking cessation is the most important intervention to prevent NSCLC. Advising smokers to stop smoking and preventing nonsmokers from being exposed to tobacco smoke are the most effective ways to decrease the morbidity and mortality associated with lung cancer. Current smokers should be informed of their continuing risk for lung cancer and offered cessation treatments. Screening with LDCT should be viewed as an adjunct to tobacco cessation interventions.

RESULTS At least 1 episode of hypoglycemia was diagnosed in 1465 patients (8.8%) and dementia was diagnosed in 1822 patients (11%) during follow-up; 250 patients had both dementia and at least 1 episode of hypoglycemia (16.95%). Compared with patients with no hypoglycemia, patients with single or multiple episodes had a graded increase in risk with fully adjusted hazard ratios (HRs): for 1 episode (HR, 1.26; 95% confidence interval [CI], 1.10-1.49); 2 episodes (HR, 1.80; 95% CI, 1.37-2.36); and 3 or more episodes (HR, 1.94; 95% CI, 1.42-2.64). The attributable risk of dementia between individuals with and without a history of hypoglycemia was 2.39% per year (95% CI, 1.72%-3.01%). Results were not attenuated when medical utilization rates, length of health plan membership, or time since initial diabetes diagnosis were added to the model. When examining emergency department admissions for hypoglycemia for association with risk of dementia (535 episodes), results were similar (compared with patients with 0 episodes) with fully adjusted HRs: for 1 episode (HR, 1.42; 95% CI, 1.12-1.78) and for 2 or more episodes (HR, 2.36; 95% CI, 1.57-3.55). CONCLUSIONS Among older patients with type 2 diabetes, a history of severe hypoglycemic episodes was associated with a greater risk of dementia.

The nature of the relationship of obesity with adverse clinical outcomes in nondialysis-dependent CKD and the putative interaction of the severity of disease with this association are unclear. We analyzed data from a nationally representative cohort of 453,946 United States veterans with eGFR<60 ml/min per 1.73 m(2). The associations of body mass index categories (<20, 20 to <25, 25 to <30, 30 to <35, 35 to <40, 40 to <45, 45 to <50, and ≥50 kg/m(2)) with all-cause mortality and disease progression (using multiple definitions, including incidence of ESRD, doubling of serum creatinine, and the slopes of eGFR) were examined in Cox proportional hazards models and logistic regression models. Multivariable adjustments were made for age, race, comorbidities and medications, and baseline eGFR. Body mass index showed a relatively consistent U-shaped association with clinical outcomes, with the best outcomes observed in overweight and mildly obese patients. Body mass index levels <25 kg/m(2) were associated with worse outcomes in all patients, independent of severity of CKD. Body mass index levels ≥35 kg/m(2) were associated with worse outcomes in patients with earlier stages of CKD, but this association was attenuated in those patients with eGFR<30 ml/min per 1.73 m(2).

Many of them are poor candidates for stage-specific lung cancer treatment due to diminished lung function and poor functional status, and many forego treatment. The negative effect of COPD may be moderated by pulmonologist-guided management. OBJECTIVES This study examined the association between pulmonologist management and the probability of receiving the recommended stage-specific treatment modality and overall survival among patients with non-small cell lung cancer (NSCLC) with preexisting COPD. METHODS Early- and advanced-stage NSCLC cases diagnosed between 2002 and 2005 with a prior COPD diagnosis (3-24 months before NSCLC diagnosis) were identified in Surveillance, Epidemiology, and End Results tumor registry data linked to Medicare claims. Study outcomes included receipt of recommended stage-specific treatment (surgical resection for early-stage NSCLC and chemotherapy for advanced-stage NSCLC [advNSCLC]) and overall survival. Pulmonologist management was considered present if one or more Evaluation and Management visit claims with pulmonologist specialty were observed within 6 months after NSCLC diagnosis. Stage-specific multivariate logistic regression tested association between pulmonologist management and treatment received. Cox proportional hazard models examined the independent association between pulmonologist care and mortality. Two-stage residual inclusion instrumental variable (2SRI-IV) analyses tested and adjusted for potential confounding based on unobserved factors or measurement error. MEASUREMENTS AND MAIN RESULTS The cohorts included 5,488 patients with early-stage NSCLC and 6,426 patients with advNSCLC disease with preexisting COPD. Pulmonologist management was recorded for 54.9% of patients with early stage NSCLC and 35.7% of patients with advNSCLC. Of those patients with pulmonologist involvement, 58.5% of patients with early NSCLC received surgical resection, and 43.6% of patients with advNSCLC received chemotherapy. Pulmonologist management post NSCLC diagnosis was associated with increased surgical resection rates (odds ratio, 1.26; 95% confidence interval, 1.11-1.45) for early NSCLC and increased chemotherapy rates (odds ratio, 1.88; 95% confidence interval, 1.67-2.10) for advNSCLC. Pulmonologist management was also associated with reduced mortality risk for patients with early-stage NSCLC but not AdvNSCLC. CONCLUSIONS Pulmonologist management had a positive association with rates of stage-specific treatment in both groups and overall survival in early-stage NSCLC.

However, there is an absence of evidence to support good practice guidelines for attention to these problems. We aimed to study the extent of this comorbidity and its impact on cognitive function and disability in population-based studies in low and middle income countries, where chronic diseases and impairments are likely to be both common and undertreated. METHODS A multicentre cross-sectional survey of all over 65 year old residents (n = 15 022) in 11 catchment areas in China, India, Cuba, Dominican Republic, Venezuela, Mexico and Peru. We estimated the prevalence of pain, incontinence, hearing and visual impairments, mobility impairment and undernutrition according to the presence of dementia and its severity, and, among those with dementia, the independent contribution of these impairments to cognitive function and disability, adjusting for age, gender, education and dementia severity. RESULTS Incontinence, hearing impairment, mobility impairment and undernutrition were consistently linearly associated with the presence of dementia and its severity across regions. Among people with dementia, incontinence, hearing impairment and mobility impairment were independently associated with disability in all regions while the contributions of pain, visual impairment and undernutrition were inconsistent. Only hearing impairment made a notable independent contribution to cognitive impairment.

Diffusion tensor imaging provides a unique opportunity to investigate the extent and nature of structural injury, but has been limited by examining only a subset of regions of interest (ROI) and by confounds common to the study of an elderly population, including comorbid vascular pathology. Furthermore, comprehensive correlation of diffusion tensor imaging (DTI) measurements, including axial and radial diffusivity measurements, has not been demonstrated in the late life depression population. METHODS 51 depressed and 16 non-depressed, age- and cerebrovascular risk factor-matched elderly subjects underwent traditional anatomic T1 and T2 weight imaging, as well as DTI. The DTI data were skeletonized using tract based spatial statistics (TBSS), and both regional and global analyses were performed. RESULTS Widespread structural abnormalities within white matter were detected in the LLD group, accounting for age, gender and education and matched for cerebrovascular risk factors and global T2 white matter hyperintensities (T2WMH). Regional differences were most prominent in uncinate and cingulate white matter and were generally characterized by an increase in radial diffusivity. Age-related changes particularly in the cingulate bundle were more advanced in individuals with LLD relative to controls. Regression analysis demonstrated significant correlations of regional fractional anisotropy and radial diffusivity with five different neuropsychological factor scores. TBSS analysis demonstrated a greater extent of white matter abnormalities in LLD not responsive to treatment, as compared to controls. CONCLUSIONS White matter integrity is compromised in late life depression, largely manifested by increased radial diffusivity in specific regions, suggesting underlying myelin injury. A possible mechanism for underlying myelin injury is chronic white matter ischemia related to intrinsic cerebrovascular disease. In some regions such as the cingulate bundle, the white matter injury related to late life depression appears to be independent of and compounded by age-related changes. The correlations with neuropsychological testing indicate the essential effects of white matter injury on functional status. Lastly, response to treatment may depend on the extent of white matter injury, suggesting a need for intact functional networks.", "title": "Diminished performance on neuropsychological testing in late life depression is correlated with microstructural white matter abnormalities." }, { "docid": "32777637", "text": "BACKGROUND Concurrent use of multiple standing antipsychotics (antipsychotic polypharmacy) is increasingly common among both inpatients and outpatients. Although this has often been cited as a potential quality-of-care problem, reviews of research evidence on antipsychotic polypharmacy have not distinguished between appropriate versus inappropriate use. METHODS A MEDLINE search from 1966 to December 2007 was completed to identify studies comparing changes in symptoms, functioning, and/or side effects between patients treated with multiple antipsychotics and patients treated with a single antipsychotic. The studies were reviewed in two groups on the basis of whether prescribing was concordant with guideline recommendations for multiple-antipsychotic use. RESULTS A review of the literature, including three randomized controlled trials, found no support for the use of antipsychotic polypharmacy in patients without an established history of treatment resistance to multiple trials of monotherapy. In patients with a history of treatment resistance to multiple monotherapy trials, limited data support antipsychotic polypharmacy, but positive outcomes were primarily found in studies of clozapine augmented with a second-generation antipsychotic. DISCUSSION Research evidence is consistent with the goal of avoiding antipsychotic polypharmacy in patients who lack guideline-recommended indications for its use. The Joint Commission is implementing a core measure set for Hospital-Based Inpatient Psychiatric Services. Two of the measures address antipsychotic polypharmacy. The first measure assesses the overall rate. The second measure determines whether clinically appropriate justification has been documented supporting the use of more than one antipsychotic medication.", "title": "When is antipsychotic polypharmacy supported by research evidence?

However, the CA feels that since my withdrawal and deposit mechanism in NRO is cash, I might be subject to questioning. Is there any issues in doing the above? The CA is right. The Cash Withdrawal and Cash Deposit has broken the link between the money withdrawn and the money deposited. It could easily be the case that the Cash Withdrawals were spent on expenses and the Cash Deposit is new (taxable) income to you. This new income needs to be declared and the taxes paid. If you Uncle is a close relative (the exact relationships that are called close relatives are defined by law), the return of the money can be declared to be a gift from your Uncle to you and no taxes are due from you on the money. If the funds are large, it is advised to have a gift deed. It is not a simple matter of creating a gift deed stating that your Uncle has given you a gift; your Uncle has to show how he acquired so many assets that he gave you some money as a gift and whether appropriate taxes were paid by him. If your Uncle is not a close relative, he can still gift you up to Rs 50,000 per year without you having to pay any income tax on the money received, but again, a gift deed would be needed to account for the cash deposits.

Investors will correctly assume that the future earnings of home builders will be higher than they were, say ten years ago. Seeking to capitalize on these higher earnings, they will try to buy the stocks. However, the current owners of the stock, potentially the sellers, know the same thing as the investor-buyer and therefore demand a premium to entice a sale. The price of the stock has risen. The reverse is true, also. Brick and mortar retailers are declining as more consumers prefer on-line retail shopping. The current owners of these stocks will probably want to sell their stock before it is worth even less. The investor-buyer also knows the same facts; that future earnings will most likely be less for these companies. The potential buyer offers a very low price to entice a sale. The price of the stock has fallen. Finally, the price of stocks rise and fall with general market conditions. As an example, assume that next months jobs report is released showing that 350,000 new jobs were created in July. Investors will believe that if companies are hiring, then the companies are doing well; they are selling products and services at a higher than expected rate, requiring that they add new employees.

Most governments, given the choice, would take lowered tax payments and more jobs over no tax payments and no jobs. Since I was curious, I decided to do a quick back-of-the-envelope calculation of this project using a common economic impact model. I used a conservative assumption of 3,000 new jobs (the minimum Foxconn expects to have by 2020, and well below the maximum capacity of the factory) in the Audio and Video Equipment Manufacturing (6-digit NAICS code of 334310) industry, using the entire State of Wisconsin as a geography. This industry has average annual earnings in Wisconsin of $56,000, so I subtracted out $3,000 per job to make it in line with the article. I also used the liberal assumption that 100% of these jobs will be considered \"\"net new\"\" or that they won't be replacing or destroying any existing jobs within the state. The results: - Salaries alone will amount to about $160 million per year, assuming all workers receive the same salary of $53,000. - Indirect effects (basically new jobs and spending for other industries used to support and maintain the factory, that aren't directly employed by the factory itself) will add an additional $20 million in earnings annually. - Finally, induced effects (the economic impact of new employees spending their salaries within the economy) will add an additional $80 million. - Total change in jobs (including factory workers, maintenance and utility workers, and new workers in supply chain industries) is estimated as just north of 5,000. This adds up to $260 million in additional annual earnings within the Wisconsin economy. There is a lot more to be considered when looking at a project like this, and there are **a lot** of ways Wisconsin or Foxconn can fuck this all up, but it isn't out of the realm of possibility that attracting this new plant will end up being a worthwhile plan for Wisconsin. Also, this quote: &gt;“We are calling this development ‘Wisconn Valley,’ ” he said, speaking from the East Room of the White House, “because we believe this will have a transformational effect on Wisconsin just as Silicon Valley transformed the San Francisco Bay area.” Sounds like bullshit.

Real estate agent best practice
[ { "docid": "311655", "text": "\"There are people that make up a small segment of the population that have an unsatisfied need to see the insides of other people's houses. There's also a segment of the population that don't quite understand the \"\"big picture\"\" of how service professions work... for example, any group of friends going into a restaurant and requesting a table and sitting at it for over an hour, but feel they don't need to leave a tip because they only ordered espressos or shared a desert. Sure, you're paying for the service of a service professional, but it should also include their time and resources you consume outside of the actual service but many don't have that perspective. Why should I pay you if you aren't providing your actual \"\"service\"\" to me even though I'm consuming your time and resources that would be earning you your expected salary otherwise, is their justification. So when you encounter an individual from both small segments of the population mentioned above, the result is the problem your wife faces with perspective buyers. I look at the Agent / Buyer relationship from a different perspective when I encounter these no-harm intended individuals. I don't see it as the buyer is hiring the agent... for if that was the case, a contract of some sorts would be involved detailing the menu of services provided by the agent with associated costs, the buyer would make selections from the menu, pay the costs, and services rendered. but that's not how it works. so its important to understand the perspective of the agent looking to hire the buyer.. you're not paying the buyer to be your client, but you are looking to select the prospective buyer that's going to generate cash flow. In a commissions based work force that is also your main source of income, you have to look at prospective clients as that.. simply prospects..but who are a vital component of your salary. So when allocating your time and resources, especially if you're dealing with several prospects, you literally have to turn away these cold leads who are just looking for design tips and paint color pattern suggestions and you as their escort. If I was in the shoe-making business, i wouldn't hire a walk-in, give him access to materials and work space with the assumption that if its to his liking, it'll generate profit towards my salary needs, if the only thing he's interested in doing is looking around at all the other shoes, a behavior that requires my presence, time, and resources. You almost can't even justify it as \"\"looking at it as possible income in the future\"\" if it's costing you revenue now, whether its in the form of having to neglect actual buyers or you could be investing your time in things that would impact salary needs, such as advance course work (attending optional trainings offered by your broker), or investing time finding more serious leads.\"", "title": "" }, { "docid": "479616", "text": "This question is a bit off-topic, might be better moved to another SE site.

Keep in mind no one can take advantage of you without your permission. There are also some things you and she can do to reduce the amount of wasted time while minimizing the risk of giving up on a potential sale. Qualify your leads: make sure these potential clients are really, truly potential customers. Ask whatever questions you have to ask in order to qualify them as real house hunters. It doesn't have to be binary: you can have hot leads ready to buy now, and lukewarm leads who may not buy for 12 months or more. Treat each one accordingly. Set limits: a lukewarm lead is not allowed to call you 20 times a day. Answer their calls just once per day. By answering the phone every time they call you are training them to call as often as they like! If you only return calls once per day they'll quickly learn to save their questions up and ask them all at once. Showing 10 houses sounds a bit silly. How can you remember any details after seeing 10 houses? By asking more questions and learning more about what your clients want in a house, you can reduce the footwork. Me, I'd flat out limit it to three houses per outing, and I wouldn't even hesitate to tell the client why. I think all these things will come in time.

The rest: Your main concern is that the broker will find you a place at the top of your budget and will not negotiate aggressively. The main person responsible for negotiation is YOU. You are paying for the property, and you are putting in bids: not your agent. The agent should advise you, but in the end should pass along your bids directly. The real problem is that you, as the buyer, generally do not have as close a feel for the pulse of the market as the broker, who should be quite aware of recent closings in the neighborhood. Therefore, there are a few things that you can do to help arm yourself: At the end of the day, if you have decided to use a broker, you are making a large financial commitment to hire someone to find you the best place, and therefore it may be more important at this point to spend your efforts shopping around for the best broker, rather than trying to figure out how to outsmart her. You are correct: buyers' agents DO have incentives to sell you on places that may not be right or good for you. For example: Although your scheme may help a bit with the first concern, it will not help at all with the other two, which I assume to be much more likely problems in any event. Instead, find recommendations for brokers from others. Have the broker show you a few properties and put in some low bids to get a feel for how she handles them. Discuss the properties together and try to assess if they really have your interests in mind. You are paying a lot for their service, and you should make sure, as much as possible, that they really are working honestly and in your best interest.

There are young couples with great incomes and no debt, who blow away the required ratios for proposed debt to income, but haven't saved up the otherwise huge 20% downpayment. Then there are those who have saved for years, even having 30% to put down, but their income is still not going to qualify them. The offer will be contingent on the financing, regardless.

A Low Methionine Diet May Help Starve Cancer Cells
[ { "docid": "MED-3715", "text": "INTRODUCTION: Questions have recently arisen in the popular press about the association between specific sexual behaviors, namely, fellatio and cunnilingus, with head and neck cancers. Although there has been an overall decline in the incidence of head and neck cancers over the past 25 years, there has been a shift in the distribution of these cancers toward a particular type known as oral squamous cell carcinomas (OSCCs), and a younger demographic. These particular cancers, OSCCs, have been shown to be associated with the human papillomavirus (HPV). Several researchers have suggested that this shift in the epidemiology of head and neck cancers might be attributable to changing sexual practices. While this speculation has caught on in the popular press, there are several interesting contradictions in the existing evidence that suggest this conclusion might be premature and overreached. AIM: The intent of this article is to help clarify the issues so that sexual medicine professionals can give accurate and up-to-date information to their patients. MAIN OUTCOME MEASURES: This is a review article; no outcome data are reported. This is a review article; no measures were collected. METHODS: Pubmed search on HPV, oral sex, oral cancers, and OSCCs. RESULTS: One hundred ninety-six articles on HPV were found; 63 articles on oral sex, 55 on oral cancer, and 5 articles on OSCCs were identified as relevant. CONCLUSIONS: HPV infections occur commonly and are usually cleared within 18 months, thus HPV infection should not be a cause for concern among monogamous couples with a rich and varied sex life as long as the sexual system remains closed and other immune compromising factors are not present. HPV becomes a concern in the context of immune system compromise and infection persistence.

METHOD: The Western Australian Pregnancy Cohort (Raine) Study is a prospective study of 2900 pregnancies recruited from 1989-1992. At 14 years of age (2003-2006; n=1324), the Child Behaviour Checklist (CBCL) was used to assess behaviour (characterising mental health status), with higher scores representing poorer behaviour. Two dietary patterns (Western and Healthy) were identified using factor analysis and food group intakes estimated by a 212-item food frequency questionnaire. Relationships between dietary patterns, food group intakes and behaviour were examined using general linear modelling following adjustment for potential confounding factors at age 14: total energy intake, body mass index, physical activity, screen use, family structure, income and functioning, gender and maternal education at pregnancy. RESULTS: Higher total (b=2.20, 95% CI=1.06, 3.35), internalizing (withdrawn/depressed) (b=1.25, 95% CI=0.15, 2.35) and externalizing (delinquent/aggressive) (b=2.60, 95% CI=1.51, 3.68) CBCL scores were significantly associated with the Western dietary pattern, with increased intakes of takeaway foods, confectionary and red meat. Improved behavioural scores were significantly associated with higher intakes of leafy green vegetables and fresh fruit (components of the Healthy pattern).

Glycolytic metabolism is markedly accelerated in cancer cells, causing the accumulation of glucose (a reducing sugar) and methionine (an amino acid), which can non-enzymatically react and form carcinogenic substances. There is speculation that this reaction produces gaseous sulfur-containing compounds in tumour tissue. The aims of this study were to clarify the products in tumour and to investigate their effect on tumour proliferation. METHODS: Products formed in the reaction between glucose and methionine or its metabolites were analysed in vitro using gas chromatography. Flatus samples from patients with colon cancer and exhaled air samples from patients with lung cancer were analysed using near-edge x-ray fine adsorption structure spectroscopy and compared with those from healthy individuals. The tumour proliferation rates of mice into which HT29 human colon cancer cells had been implanted were compared with those of mice in which the cancer cells were surrounded by sodium hyaluronate gel to prevent diffusion of gaseous material into the healthy cells. RESULTS: Gaseous sulfur-containing compounds such as methanethiol and hydrogen sulfide were produced when glucose was allowed to react with methionine or its metabolites homocysteine or cysteine. Near-edge x-ray fine adsorption structure spectroscopy showed that the concentrations of sulfur-containing compounds in the samples of flatus from patients with colon cancer and in the samples of exhaled air from patients with lung cancer were significantly higher than in those from healthy individuals. Animal experiments showed that preventing the diffusion of sulfur-containing compounds had a pronounced antitumour effect. CONCLUSIONS: Gaseous sulfur-containing compounds are the main products in tumours and preventing the diffusion of these compounds reduces the tumour proliferation rate, which suggests the possibility of a new approach to cancer treatment.", "title": "Generation of gaseous sulfur-containing compounds in tumour tissue and suppression of gas diffusion as an antitumour treatment." }, { "docid": "MED-3732", "text": "Background Endoscopic submucosal dissection (ESD) is an advanced technique of therapeutic endoscopy alternative to endoscopic mucosal resection (EMR) for superficial gastrointestinal neoplasms >2 cm. ESD allows for the direct dissection of the submucosa and large lesions can be resected en bloc. ESD is not limited by resection size, increases histologically complete resection rates and may reduce the local recurrence. Nevertheless, the technique is time-consuming, technically demanding and associated with a high complication rate. To reduce the risk of complications, different devices and technical advances have been proposed with conflicting results and, still, ESD en bloc resections of huge lesions are associated with increased complications. Case Presentation We successfully used a combined ESD/EMR technique for huge rectal laterally spreading tumors (LSTs). ESD was used for circumferential resection of 2/3 of the lesion followed by piecemeal resection (2-3 pieces) of the central part of the tumour. In all three patients we obtained the complete dissection of the polyp and the complete histological evaluation in absence of complications and recurrence at 6 months' follow up. Conclusions In the treatment of rectal LSTs, the combined treatment - ESD/EMR resection may be considered a suitable therapeutic option, indicated in selected cases as an alternative to surgery, in which the two techniques are neither reliable nor safe separately. However, to confirm our results, larger trials with longer follow up are required together with improvement of the technique and of the technical devices.", "title": "Rectal laterally spreading tumors successfully treated in two steps by endoscopic submucosal dissection and endoscopic mucosal resection" }, { "docid": "MED-3549", "text": "Studies have shown that fisetin, a small phytochemical molecule, has antitumor activity; however, its antiangiogenic activity has not yet been examined.

Fisetin-caused cell death was accompanied by decreased expression of survivin and an increase in cleaved levels of caspases-3 and -7 and poly-(ADP-ribose) polymerase along with an increased ratio of Bax to Bcl-2. Furthermore, fisetin inhibited capillary-like tube formation on Matrigel (up to 85%, P < 0.001) as well as migration (up to 66%, P < 0.001), which were associated with decreased expression of endothelial nitric oxide synthase (eNOS) and VEGF in HUVEC.

Evidence is also reviewed that suggests that the immune response may vary qualitatively and quantitatively during progression, such that there seems to be, during oncogenesis, a very low level of immune reaction that aids initial tumor growth, followed by a larger reaction that may cause remission of early neoplasms, followed, if the neoplasm survives, by a relative immunologic tolerance to the tumor that may be dependent, at least in part, on suppressor cells.

The objective of this study was to determine the effect on synergism in activity from the sequenced combinations of cisplatin (Cis) with curcumin (Cur) and epigallocatechin-3-gallate (EGCG) in the human ovarian cancer cell lines. The drugs were added in binary combinations: Cis combined with Cur, and Cis combined with EGCG to the human ovarian A2780 and A2780(cisR) cancer cell lines, using five different sequences of administration: 0/0 h, 4/0 h, 0/4 h, 24/0 h and 0/24 h. The combination index (CI) was used to assess the combined action of the drugs. CIs <1, =1 and >1 indicated synergism, additiveness and antagonism respectively. Cellular accumulation of platinum and platinum-DNA binding levels from Cis and its combination with the phytochemicals were determined using graphite furnace atomic absorption spectrometry. Addition of Cis 4 h before Cur and EGCG (0/4 h combination) produced the most synergistic outcomes in both the A2780 and A2780(cisR) cell lines. The cellular accumulations of platinum and platinum-DNA binding resulting from the 0/4 h combinations were greater as compared to the values using Cis alone, thus providing an explanation for the synergistic action. When sequenced combinations of Cis with Cur and with EGCG are applied to human ovarian A2780 and A2780(cisR) cancer cell lines, lower concentrations and shorter time gap between the two additions seem to produce a higher cytotoxic effect.", "title": "Synergism from sequenced combinations of curcumin and epigallocatechin-3-gallate with cisplatin in the killing of human ovarian cancer cells." }, { "docid": "MED-4609", "text": "Two pandemics of heart attack deaths have plagued the world's population during the past 130 years. The first pandemic, induced by beriberi, was caused by the industrial revolution altering the nutritional composition of rice. By 1892 a simple working knowledge, then at hand, could have terminated the beriberi plague; however, orthodox medicine being then enchanted with the false concept that all disease was caused by germs, permitted millions of Asians to die needlessly of beriberi by refusing to tell them to eat rice bran or to drink rice bran tea. A second pandemic of heart attack deaths, called myocardial infarction (MI), struck the developed nations of the Western World in full force after 1930. As a hypothesis, it is suggested that this MI pandemic, still raging today, was caused by a change in food processing that occurred after 1920, when the new oil seed industry introduced into our food three greatly harmful lipid substances. The unnatural trans-trans isomer of linoleic acid, which had never been in human food prior to 1920 and which entered our food in margarines and refined oils, blocked the conversion of natural cis-cis linoleic acid to prostaglandin E1, which tends to prevent MI, both by acting as a vasodilator and by minimizing platelet aggregation. Harmful lactones were also introduced into our food, increasing the risk of MI by decreasing the fibrinolytic activity of our blood. The oil seed industry also introduced into our diet free radical lipid peroxides that make the myocardium more vulnerable to infarction. It is suggested that except for the one in 500 of us who is afflicted by familial hypercholesterolemia, the cholesterol concept of MI is as false today as was the concept in 1900 that germs caused beriberi. It is further suggested that a working knowledge is at hand today that can make death from MI just as rare as death is now from a beriberi-induced heart attack.", "title": "The beriberi analogy to myocardial infarction." }, { "docid": "MED-4886", "text": "OBJECTIVES: Previous research has demonstrated that patients with prostate cancer participating in the Prostate Cancer Lifestyle Trial had a reduction in prostate-specific antigen (PSA) levels, inhibition of LNCaP cell growth, and fewer prostate cancer-related clinical events at the end of 1 year compared with controls. The aim of this study was to examine the clinical events in this trial during a 2-year period. METHODS: The Prostate Cancer Lifestyle Trial was a 1-year randomized controlled clinical trial of 93 patients with early-stage prostate cancer (Gleason score <7, PSA 4-10 ng/mL) undergoing active surveillance. The patients in the experimental arm were encouraged to adopt a low-fat, plant-based diet, to exercise and practice stress management, and to attend group support sessions. The control patients received the usual care. RESULTS: By 2 years of follow-up, 13 of 49 (27%) control patients and 2 of 43 (5%) experimental patients had undergone conventional prostate cancer treatment (radical prostatectomy, radiotherapy, or androgen deprivation, P < .05). No differences were found between the groups in other clinical events (eg, cardiac), and no deaths occurred. Three of the treated control patients but none of the treated experimental patients had a PSA level of >or=10 ng/mL, and 1 treated control patient but no treated experimental patients had a PSA velocity of >2 ng/mL/y before treatment.

Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained from multiple logistic regression models applied on quartiles of factor scores, adjusting for potential confounding variables. RESULTS: We identified five major dietary patterns, named 'animal products and related components', 'vitamins and fiber', 'starch-rich', 'other polyunsaturated fatty acids and vitamin D', and 'other fats'. The 'animal products and related components' pattern was positively related to esophageal cancer (OR = 1.64, 95% CI:1.06-2.55, for the highest versus the lowest quartile of factor scores category).

Novel treatment strategies for advanced cancer are therefore desperately needed. Dietary restriction of the essential amino acid methionine offers promise as such a strategy, either alone or in combination with chemotherapy or other treatments. Numerous in vitro and animal studies demonstrate the effectiveness of dietary methionine restriction in inhibiting growth and eventually causing death of cancer cells. In contrast, normal host tissues are relatively resistant to methionine restriction. These preclinical observations led to a phase I clinical trial of dietary methionine restriction for adults with advanced cancer. Preliminary findings from this trial indicate that dietary methionine restriction is safe and feasible for the treatment of patients with advanced cancer. In addition, the trial has yielded some preliminary evidence of antitumor activity. One patient with hormone-independent prostate cancer experienced a 25% reduction in serum prostate-specific antigen (PSA) after 12 weeks on the diet, and a second patient with renal cell cancer experienced an objective radiographic response.

The purpose of our study was to determine whether a high-fat meal (HFM) would increase airway inflammation and decrease pulmonary function in healthy subjects.

Whereas reported age-adjusted prevalence rates of PD tend to be relatively uniform throughout Europe and the Americas, sub-Saharan black Africans, rural Chinese, and Japanese, groups whose diets tend to be vegan or quasi-vegan, appear to enjoy substantially lower rates. Since current PD prevalence in African-Americans is little different from that in whites, environmental factors are likely to be responsible for the low PD risk in black Africans. In aggregate, these findings suggest that vegan diets may be notably protective with respect to PD. However, they offer no insight into whether saturated fat, compounds associated with animal fat, animal protein, or the integrated impact of the components of animal products mediates the risk associated with animal fat consumption. Caloric restriction has recently been shown to protect the central dopaminergic neurons of mice from neurotoxins, at least in part by induction of heat-shock proteins; conceivably, the protection afforded by vegan diets reflects a similar mechanism. The possibility that vegan diets could be therapeutically beneficial in PD, by slowing the loss of surviving dopaminergic neurons, thus retarding progression of the syndrome, may merit examination.

Soy protein, as well as many other vegan proteins, are higher in non-essential amino acids than most animal-derived food proteins, and as a result should preferentially favor glucagon production. Acting on hepatocytes, glucagon promotes (and insulin inhibits) cAMP-dependent mechanisms that down-regulate lipogenic enzymes and cholesterol synthesis, while up-regulating hepatic LDL receptors and production of the IGF-I antagonist IGFBP-1. The insulin-sensitizing properties of many vegan diets--high in fiber, low in saturated fat--should amplify these effects by down-regulating insulin secretion. Additionally, the relatively low essential amino acid content of some vegan diets may decrease hepatic IGF-I synthesis. Thus, diets featuring vegan proteins can be expected to lower elevated serum lipid levels, promote weight loss, and decrease circulating IGF-I activity. The latter effect should impede cancer induction (as is seen in animal studies with soy protein), lessen neutrophil-mediated inflammatory damage, and slow growth and maturation in children. In fact, vegans tend to have low serum lipids, lean physiques, shorter stature, later puberty, and decreased risk for certain prominent 'Western' cancers; a vegan diet has documented clinical efficacy in rheumatoid arthritis. Low-fat vegan diets may be especially protective in regard to cancers linked to insulin resistance--namely, breast and colon cancer--as well as prostate cancer; conversely, the high IGF-I activity associated with heavy ingestion of animal products may be largely responsible for the epidemic of 'Western' cancers in wealthy societies. Increased phytochemical intake is also likely to contribute to the reduction of cancer risk in vegans. Regression of coronary stenoses has been documented during low-fat vegan diets coupled with exercise training; such regimens also tend to markedly improve diabetic control and lower elevated blood pressure. Risk of many other degenerative disorders may be decreased in vegans, although reduced growth factor activity may be responsible for an increased risk of hemorrhagic stroke. By altering the glucagon/insulin balance, it is conceivable that supplemental intakes of key non-essential amino acids could enable omnivores to enjoy some of the health advantages of a vegan diet.

The biochemical mechanism for methionine dependency has been studied extensively, but the fundamental mechanism remains unclear. A number of investigators have attempted to exploit the methionine dependence of tumors for therapeutic effects in vivo. To reduce in vivo methionine in plasma and tumours, dietary and pharmacological treatments have been used. Methionine-free diet or methionine-deprived total parenteral nutrition causes regression of a variety of animal tumours. Alternatively, methionine depletion was achieved by the use of methioninase. This enzyme specifically degrades methionine and inhibits tumour growth in preclinical models. Because of potential toxicity and quality of life problems, prolonged methionine restriction with diet or with methioninase is not suitable for clinical use. Methionine restriction may find greater application in association with various chemotherapeutic agents.

The number of reports demonstrating that flavonoids are an effective natural inhibitor of cancer invasion and metastasis is increasing in the scientific literature. Catechin derivatives, (−)-epigallocatechin-3-gallate, (−)-epigallocatechin, (−)-epicatechin-3-gallate,and (−)-epicatechin, are the most studied compounds in this topic so far; genistein/genistin, silibinin, quercetin, and anthocyanin have also been widely investigated for their inhibitory activities on invasion/metastasis. Other flavonoids in dietary vegetable foods that are responsible for anti-invasive and anti-metastatic activities of tumors include luteolin,apigenin, myricetin, tangeretin, kaempferol, glycitein, licoricidin,daidzein, and naringenin. To effectively overcome the metastatic cascade, including cell-cell attachment, tissue barrier degradation, migration, invasion, cell-matrix adhesion,and angiogenesis, it is essential that a bioactive compound prevent tumor cells from metastasizing. This review summarizes the effects of flavonoids on the metastatic cascade and the related proteins, the in vitro anti-invasive activity of flavonoids against cancer cells, and the effects of flavonoids on antiangiogenic and in vivo anti-metastatic models. The available scientific evidence indicates that flavonoids are a ubiquitous dietary phenolics subclass and exert extensive in vitro anti-invasive and in vivo anti-metastatic activities.", "title": "Flavonoids, a ubiquitous dietary phenolic subclass, exert extensive in vitro anti-invasive and in vivo anti-metastatic activities." }, { "docid": "MED-3553", "text": "Several epidemiological studies have indicated that abundant consumption of foods from plant origin is associated with a reduced risk of developing several types of cancers. This chemopreventive effect is related to the high content of these foods in phytochemicals, such as polyphenols, that interfere with several processes involved in cancer progression including tumor cell growth, survival and angiogenesis. In addition to the low intake of plant-based foods, increased body mass and physical inactivity have recently emerged as other important lifestyle factors influencing cancer risk, leading to the generation of low-grade chronic inflammatory conditions which are a key process involved in tumor progression. The objectives of the current study are to investigate the inhibitory effects of these polyphenols on angiogenesis triggered by an inflammatory cytokine (IL-6) and to determine the mechanisms underlying this action. We found that, among the tested polyphenols, apigenin and luteolin were the most potent angiogenesis inhibitors through their inhibitory effect on the inflammatory cytokine IL-6/STAT3 pathway. These effects resulted in modulation of the activation of extracellular signal-regulated kinase-1/2 signaling triggered by IL-6, as well as in a marked reduction in the proliferation, migration and morphogenic differentiation of endothelial cells. Interestingly, these polyphenols also modulated the expression of IL-6 signal transducing receptor (IL-6Rα) and the secretion of the extracellular matrix degrading enzyme MMP-2 as well as the expression of suppressor of cytokine signaling (SOCS3) protein. Overall, these results may provide important new information on the role of diet in cancer prevention. Copyright © 2012 Elsevier Inc.

High-fat diet associated triglyceride-rich lipoproteins have also been suggested to be atherogenic. To assess the direct effect of postprandial triglyceride-rich lipoproteins on endothelial function, an early factor in atherogenesis--10 healthy, normocholesterolemic volunteers--were studied before and for 6 hours after single isocaloric high- and low-fat meals (900 calorie; 50 and 0 g fat, respectively). Endothelial function, in the form of flow-mediated vasoactivity, was assessed in the brachial artery using 7.5-MHz ultrasound as percent arterial diameter change 1 minute after 5 minutes of upper-arm arterial occlusion. Serum lipoproteins and glucose were determined before eating and 2 and 4 hours postprandially. Serum triglycerides increased from 94 +/- 55 mg/dl preprandially to 147 +/- 80 mg/dl 2 hours after the high-fat meal (p = 0.05). Flow-dependent vasoactivity decreased from 21 +/- 5% preprandially to 11 +/- 4%, 11 +/- 6%, and 10 +/- 3% at 2, 3, and 4 hours after the high-fat meal, respectively (all p <0.05 compared with low-fat meal data). No changes in lipoproteins or flow-mediated vasoactivity were observed after the low-fat meal. Fasting low-density lipoprotein cholesterol correlated inversely (r = -0.47, p = 0.04) with preprandial flow-mediated vasoactivity, but triglyceride level did not. Mean change in postprandial flow-mediated vasoactivity at 2, 3, and 4 hours correlated with change in 2-hour serum triglycerides (r = -0.51, p = 0.02).

We randomly assigned 75 patients identified by endoscopy to have dysplastic esophageal premalignant lesions to receive freeze-dried strawberry powder at either 30 g/d (37 patients) or 60 g/d (38 patients) for six months; the powder was mixed with water and drunk. After six months, we assessed the changes in histologic grade of these lesions (primary endpoint) in a blinded fashion.

Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) Scale. Dietary patterns were derived by using principal component analysis of the consumption of 52 food and beverage items, which was assessed by a validated brief diet history questionnaire.

Findings for lacto-ovo vegetarians (β = −9·1, P<0·001 and β = −5·8, P<0·001) were similar. The vegetarians (mainly the vegans) were also less likely to be using antihypertensive medications.

Participants were grouped as vegan, lacto ovo vegetarian, pesco vegetarian, semi-vegetarian or non-vegetarian (reference group). A follow-up questionnaire after two years elicited information on the development of diabetes. Cases of diabetes developed in 0.54% of vegans, 1.08% of lacto ovo vegetarians, 1.29% of pesco vegetarians, 0.92% of semi-vegetarians and 2.12% of non-vegetarians. Blacks had an increased risk compared to non-Blacks (odds ratio [OR] 1.364; 95% confidence interval [CI], 1.093–1.702). In multiple logistic regression analysis controlling for age, gender, education, income, television watching, physical activity, sleep, alcohol use, smoking and BMI, vegans (OR 0.381; 95% CI 0.236–0.617), lacto ovo vegetarians (OR 0.618; 95% CI 0.503–0.760) and semi-vegetarians (OR 0.486, 95% CI 0.312–0.755) had a lower risk of diabetes than non-vegetarians.

Methods Identification and quantitation of CS, CG, and CR in RE was performed by mass spectroscopy and HPLC. RE:triacetyl-β-cyclodextrin (TA-β-CD) inclusion complex (IC) was prepared by a kneading method and characterized by X-ray diffraction (XRD), nuclear magnetic resonance spectroscopy (NMR) and UV-visible spectroscopy. RE or RE:TA-β-CD IC-loaded PLGA or PLA implants were prepared by a solvent extrusion method. In vitro and in vivo controlled release studies were conducted in phosphate-buffered saline Tween-80 (pH 7.4, 37°C) and after subcutaneous administration in male Sprague-Dawley rats, respectively. Anthocyanins were quantified by HPLC at 520 nm. Results The content of CS, CG, and CR in RE was 0.2, 1.5, and 3.5 wt%, respectively. The chemical stability of anthocyanins in solution was determined to be pH-dependent, and their degradation rate increased with an increase in pH from 2.4 to 7.4. PLGA/PLA millicylindrical implants loaded with 5 or 10 wt% RE exhibited a high initial burst and short release duration of anthocyanins (35–52 and 80–100% CG + CR release after 1 and 14 days, respectively). The cause for rapid anthocyanins release was linked to higher polymer water uptake and porosity associated with the high osmolytic components of large non-anthocyanin fraction of RE. XRD, 1H NMR and UV-visible spectroscopy indicated that the non-anthocyanin fraction molecules of RE formed an IC with TA-β-CD, decreasing the hydrophilicity of RE. Formation of an IC with hydrophobic carrier, TA-β-CD, provided better in vitro/in vivo sustained release of FBR anthocyanins (16–24 and 97–99% CG + CR release, respectively, after 1 and 28 days from 20 wt% RE:TA-β-CD IC/PLA implants) over 1 month, owing to reduced polymer water uptake and porosity.

The burden of non-communicable diseases (NCDs) is increasing rapidly in the developing world, very much as a result of changes in lifestyles. In addition to changes in tobacco use and physical activity, major changes are taking place in diets, contributing greatly to the growing epidemic of NCD. Thus, a huge global public health challenge is how to influence the trends in diet and nutrition for effective global NCD prevention. The health transition took place rapidly in Finland after World War II and mortality from cardiovascular disease (CVD) was exceptionally high. The North Karelia Project was launched in 1972 as a community-based, and later as a national, programme to influence diet and other lifestyles that are crucial in the prevention of CVD. The intervention had a strong theory base and it employed comprehensive strategies. Broad community organisation and the strong participation of people were the key elements. Evaluation has shown how the diet (particularly fat consumption) has changed and how these changes have led to a major reduction in population serum cholesterol and blood pressure levels. It has also shown how ischaemic heart disease mortality in a working-age population has declined by 73% in North Karelia and by 65% in the whole country from 1971 to 1995. Although Finland is an industrialised country, North Karelia was rural, of rather low socio-economic level and with many social problems in the 1970s and 1980s. The project was based on low-cost intervention activities, where people's participation and community organisations played a key role. Comprehensive interventions in the community were eventually supported by national activities--from expert guidelines and media activities to industry collaboration and policy. Similar principles for nutrition intervention programmes could be used in developing countries, obviously tailored to the local conditions.

However, this possibility has not been investigated yet. In this study, steady-state levels of markers of different kinds of protein damage--oxidation (glutamic and aminoadipic semialdehydes), mixed glyco- and lipoxidation (carboxymethyl- and carboxyethyllysine), lipoxidation (malondialdehydelysine) and amino acid composition--were measured in the heart of eight mammalian species ranging in maximum life span (MLSP) from 3.5 to 46 years.

Design Exhaled breath and watery stool samples were obtained from patients with CRC and from healthy controls prior to colonoscopy. Each test group consisted of one sample from a patient with CRC and four control samples from volunteers without cancer. These five samples were randomly and separately placed into five boxes. A Labrador retriever specially trained in scent detection of cancer and a handler cooperated in the tests. The dog first smelled a standard breath sample from a patient with CRC, then smelled each sample station and sat down in front of the station in which a cancer scent was detected. Results 33 and 37 groups of breath and watery stool samples, respectively, were tested. Among patients with CRC and controls, the sensitivity of canine scent detection of breath samples compared with conventional diagnosis by colonoscopy was 0.91 and the specificity was 0.99.

However, there is growing evidence that certain practical nutritional measures have the potential to slow tumor angiogenesis, and it is reasonable to anticipate that, by combining several measures that work in distinct but complementary ways to impede the angiogenic process, a clinically useful 'multifocal angiostatic therapy' (MAT) might be devised. Several measures which might reasonably be included in such a protocol are discussed below, and include: a low-fat, low-glycemic index vegan diet, which may down-regulate the systemic IGF-I activity that supports angiogenesis; supplemental omega-3-rich fish oil, which has been shown to inhibit endothelial expression of Flk-1, a functionally crucial receptor for VEGF, and also can suppress tumor production of pro-angiogenic eicosanoids; high-dose selenium, which has recently been shown to inhibit tumor production of VEGF; green tea polyphenols, which can suppress endothelial responsiveness to both VEGF and fibroblast growth factor; and high-dose glycine, whose recently reported angiostatic activity may reflect inhibition of endothelial cell mitosis, possibly mediated by activation of glycine-gated chloride channels. In light of evidence that tumor-evoked angiogenesis has a high requirement for copper, copper depletion may have exceptional potential as an angiostatic measure, and is most efficiently achieved with the copper-chelating drug tetrathiomolybdate. If logistical difficulties make it difficult to acquire this experimental drug, high-dose zinc supplementation can achieve a slower depletion of the body's copper pool, and in any case can be used as maintenance therapy to maintain an adequate level of copper depletion. A provisional protocol is offered for a nutritionally based MAT entailing a vegan diet and supplemental intakes of fish oil, selenium, green tea polyphenols, glycine, and zinc.

Chitin is an eukaryotic extracellular aminosugar biopolymer, massively produced by most fungal systems and by invertebrates, notably arthropods. Being an integral supportive component in fungal cell wall, insect cuticle, and nematode egg shell, chitin has been considered as a selective target for pesticide action. Throughout the elaborate processes of chitin formation and deposition, only the polymerization events associated with the cell membrane compartment are so far available for chemical interference. Currently, the actinomycetes-derived nucleoside peptide fungicides such as the polyoxins and the insecticidal benzoylaryl ureas have reached commercial pesticide status. The polyoxins and other structurally-related antibiotics like nikkomycins are strong competitive inhibitors of the polymerizing enzyme chitin synthase. The exact biochemical lesion inflicted by the benzoylaryl ureas is still elusive, but a post-polymerization event, such as translocation of chitin chains across the cell membrane, is suggested. Hydrolytic degradation of the chitin polymer is essential for hyphal growth, branching, and septum formation in fungal systems as well as for the normal molting of arthropods. Recently, insect chitinase activity was strongly and specifically suppressed by allosamidin, an actimomycetes-derived metabolite. In part, the defense mechanism in plants against invasion of pathogens is associated with induced chitinases. Chitin, chitosan, and their oligomers are able to act as elicitors which induce enhanced levels of chitinases in various plants.

It has been observed that protein restriction also decreases mtROS generation and oxidative stress in rat liver, whereas neither carbohydrate nor lipid restriction change these parameters. This is interesting because protein restriction also increases maximum longevity in rodents (although to a lower extent than DR) and is a much more practicable intervention for humans than DR, whereas neither carbohydrate nor lipid restriction seem to change rodent longevity.

These studies suggest that the reduced intake of dietary methionine can be responsible for the decrease in mitochondrial ROS generation and the ensuing oxidative damage that occurs during DR, as well as for part of the increase in maximum longevity induced by this dietary manipulation.

Since streptozotocin diabetes inhibits carcinogen-mediated induction of pancreatic cancer in hamsters, the most reasonable interpretation of these findings is that insulin (or some other beta cell product) acts as a promoter for pancreatic carcinogenesis. This view is consistent with a report that human pancreatic adenocarcinomas express insulin receptors that can stimulate mitosis; an additional possibility is that high insulin levels indirectly promote pancreatic carcinogenesis by boosting effective IGF-I activity via hepatic actions. In international ecologic epidemiology, pancreatic cancer rates correlate tightly with dietary intake of animal products; this may reflect the fact that vegan diets are associated with low diurnal insulin secretion. There is also suggestive evidence that macrobiotic vegan diets, which are low in glycemic index, may increase mean survival time in pancreatic cancer. However, other types of diets associated with decreased postprandial insulin response, such as high-protein diets or 'Mediterranean' diets high in oleic acid, may also have the potential for pancreatic cancer prevention. The huge increases of age-adjusted pancreatic cancer mortality in Japan and among African-Americans during the last century imply that pancreatic cancer is substantially preventable; a low-insulin-response diet coupled with exercise training, weight control, and smoking avoidance, commendable for a great many other reasons, may slash pancreatic cancer mortality dramatically.

There are multiple age-related deficits in both the innate and adaptive systems that may play a role in the increased incidence of cancer. These include decreased NK-cell function, impaired antigen uptake and presentation by monocytes and dendritic cells, an increase in 'inflammaging', a decline in the number of naïve T-cells able to respond to evolving tumor cells, and an increase in functionally exhausted senescent cells.

When Asian men adopt the US lifestyle, clinical prostate cancer increases greatly. Epidemiological data from men in the US indicate that regular activity may reduce the risk for prostate cancer. METHODS: Serum was obtained from three groups of similar-aged men, Control, Diet and Exercise, and Exercise alone were used to stimulate LNCaP cells in culture. Growth and apoptosis of tumor cells were measured. Serum samples were also used to measure insulin, IGF-1, IGFBP-1. RESULTS: The Diet and Exercise and the Exercise alone groups had lower serum insulin and IGF-1 but higher IGFBP-1 compared to Controls. LNCaP cell growth was reduced in both groups compared to Control and there was a major increase in apoptosis of tumor cells. CONCLUSIONS: A low-fat diet and/or intensive exercise results in change in serum hormones and growth factors in vivo that can reduce growth and induce apoptosis of LNCaP prostate tumor cells in vitro.

However, few prospective studies have investigated one-carbon metabolism in relation to prostate cancer risk, and the results have been conflicting. The aim of this study was to do a comprehensive investigation of the components of one-carbon metabolism in relation to prostate cancer risk. A panel of seven circulating B vitamins and related metabolites was selected, most of which have not been studied before. MATERIALS AND METHODS: We analyzed plasma concentrations of betaine, choline, cysteine, methionine, methylmalonic acid (MMA), vitamin B2, and vitamin B6 in 561 cases and 1,034 controls matched for age and recruitment date, nested within the population-based Northern Sweden Health and Disease Cohort. Relative risks of prostate cancer were estimated by conditional logistic regression. RESULTS: Positive associations with prostate cancer risk were observed for choline and vitamin B2, and an inverse association was observed for MMA. The relative risks for a doubling in concentrations were 1.46 [95% confidence interval (95% CI), 1.04-2.05; P(trend) = 0.03] for choline, 1.11 (95% CI, 1.00-1.23; P(trend) = 0.04) for vitamin B2, and 0.78 (95% CI, 0.63-0.97; P(trend) = 0.03) for MMA. Concentrations of betaine, cysteine, methionine, and vitamin B6 were not associated with prostate cancer risk. CONCLUSION: The results of this large prospective study suggest that elevated plasma concentrations of choline and vitamin B2 may be associated with an increased risk of prostate cancer.

ER(-) basal-like MDA-MB-231 and MDA-MB-436 breast cancer cell lines contained a greater number of cytoplasmic lipid droplets compared to luminal ER(+) MCF-7 cells. Therefore, we studied lipid storage functions in these cells. Both triacylglycerol and cholesteryl ester (CE) concentrations were higher in the ER(-) cells, but the ability to synthesize CE distinguished the two types of breast cancer cells. Higher baseline, oleic acid- and LDL-stimulated CE concentrations were found in ER(-) compared to ER(+) cells. The differences corresponded to greater mRNA and protein levels of acyl-CoA:cholesterol acyltransferase 1 (ACAT1), higher ACAT activity, higher caveolin-1 protein levels, greater LDL uptake, and lower de novo cholesterol synthesis in ER(-) cells. Human LDL stimulated proliferation of ER(-) MDA-MB-231 cells, but had little effect on proliferation of ER(+) MCF-7 cells. The functional significance of these findings was demonstrated by the observation that the ACAT inhibitor CP-113,818 reduced proliferation of breast cancer cells, and specifically reduced LDL-induced proliferation of ER(-) cells. Taken together, our studies show that a greater ability to take up, store and utilize exogenous cholesterol confers a proliferative advantage to basal-like ER(-) breast cancer cells.

This review describes how curcumin sensitizes cancer cells through regulation of multiple multidrug resistance pathways, thus employing one drug for multiple targets. Curcumin helps the cancer cells to regain their 'forgotten' apoptosis, modulates drug-target interaction at different levels, restrains survival pathways when their proteins are overexpressed, and finds an alternate way to carry forward the process of sensitization of different resistant tumours. Additionally, the review dissects the role of curcumin, if any, in targeting the major culprit of drug resistance, cancer stem cells (CSC), thereby circumventing resistance.

This review will summarize the current knowledge of the role of AhR in regulation of intestinal immune homeostasis and inflammation. RECENT FINDINGS: Activation of AhR by dietary ligands is necessary for the maintenance or expansion of innate immune cells in the gut, such as intraepithelial lymphocytes (IELs) and interleukin (IL)-22-producing lymphoid cells (ILC22). AhR-deficient mice lack IELs, have reduced number of ILC22 cells, and are more susceptible to bacterial infections and experimental colitis. In animal models, AhR activators inhibit proinflammatory cytokine synthesis and attenuate colitis by a pathway that involves IL-22. Analysis of AhR in the human gut reveals that intestinal T cells and natural killer cells isolated from Crohn's disease patients express low levels of AhR and respond to AhR ligands by downregulating inflammatory cytokines and upregulating IL-22.

Measurement-error corrected estimates of intake in 15 food groups were defined from a validated food frequency questionnaire in 1992. Associations with SCC risk were assessed using Poisson and negative binomial regression to the persons affected and tumour counts, respectively, based on incident, histologically confirmed tumours occurring between 1992 and 2002. After multivariable adjustment, none of the food groups was significantly associated with SCC risk. Stratified analysis in participants with a past history of skin cancer showed a decreased risk of SCC tumours for high intakes of green leafy vegetables (RR = 0.45, 95% CI = 0.22-0.91; p for trend = 0.02) and an increased risk for high intake of unmodified dairy products (RR = 2.53, 95% CI: 1.15-5.54; p for trend = 0.03).

DESIGN: Plasma growth factors and hormones were evaluated in 21 sedentary subjects, who had been eating a low-protein, low-calorie diet for 4.4 +/- 2.8 y (x +/- SD age: 53.0 +/- 11 y); 21 endurance runners matched by body mass index (BMI; in kg/m2); and 21 age- and sex-matched sedentary subjects eating Western diets. RESULTS: BMI was lower in the low-protein, low-calorie diet (21.3 +/- 3.1) and runner (21.6 +/- 1.6) groups than in the Western diet (26.5 +/- 2.7; P < 0.005) group. Plasma concentrations of insulin, free sex hormones, leptin, and C-reactive protein were lower and sex hormone-binding globulin was higher in the low-protein, low-calorie diet and runner groups than in the sedentary Western diet group (all P < 0.05).

However, the content of anthocyanins in staple foods is typically low and the mechanisms by which they exert anti-cancer activity is not yet fully defined. Methods and results We selected an anthocyanin-enriched purple-fleshed sweet potato clone, P40, and investigated its potential anti-cancer effect in both in vitro cell culture and in vivo animal model. In addition to a high level of total phenolics and antioxidant capacity, P40 possesses a high content of anthocyanins at 7.5 mg/g dry matter. Treatment of human colonic SW480 cancer cells with P40 anthocyanin extracts at 0–40 μM of peonidin-3-glucoside equivalent resulted in a dose-dependent decrease in cell number due to cytostatic arrest of cell cycle at G1 phase but not cytotoxicity. Furthermore, dietary P40 at 10–30% significantly suppressed azoxymethane-induced formation of aberrant crypt foci in the colons of CF-1 mice in conjunction with, at least in part, a lesser proliferative PCNA and a greater apoptotic caspase-3 expression in the colon mucosal epithelial cells.

Recently, SFR has been shown to promote the mitochondrial formation of reactive oxygen species (ROS) in human cancer cell lines. The present study was undertaken to see whether SFR-derived ROS might cause DNA damage in cultured human cells, namely T limphoblastoid Jurkat and human umbilical vein endothelial cells (HUVEC). 1-3 h treatments with 10-30 microM SFR elicited intracellular ROS formation (as assayed with dihydrorhodamine, DHR, oxidation) as well as DNA breakage (as assessed with fast halo assay, FHA). These effects lacked cell-type specificity, since could be observed in both Jurkat and HUVEC. Differential-pH FHA analysis of damaged DNA showed that SFR causes frank DNA single strand breaks (SSBs); no DNA double strand breaks (DSBs) were found within the considered treatment times (up to 3 h). SFR-derived ROS were formed at the mitochondrial respiratory chain (MRC) level: indeed rotenone or myxothiazol (MRC Complex I and III inhibitors, respectively) abrogated ROS formation. Furthermore ROS were not formed in Jurkat cells pharmacologically depleted of respiring mitochondria (MRC-/Jurkat). Formation of ROS was causally linked to the induction of SSBs: indeed all the experimental conditions capable of preventing ROS formation also prevented the damage of nuclear DNA from SFR-intoxicated cells. As to the toxicological relevance of SSBs, we found that their prevention slightly but significantly attenuated SFR cytotoxicity, suggesting that high-dose SFR toxicity is the result of a complex series of events among which GSH depletion seems to play a pivotal role. In conclusion, the present study identifies a novel mechanism contributing to SFR toxicity which - since DNA damage is a prominent mechanism underlying the cytotoxic activity of established antineoplastic agents - might help to exploit the therapeutic value of SFR in anticancer drug protocols.

Because IGF-I modulates cell proliferation, apoptosis, and tumorigenesis, the mechanisms behind the protective effects of DR may depend on the reduction of this multifaceted growth factor. To test this hypothesis, IGF-I was restored during DR to ascertain if lowering of IGF-I was central to slowing bladder cancer progression during DR. Heterozygous p53-deficient mice received a bladder carcinogen, p-cresidine, to induce preneoplasia. After confirmation of bladder urothelial preneoplasia, the mice were divided into three groups: (a) ad libitum; (b) 20% DR; and (c) 20% DR plus IGF-I (IGF-I/DR). Serum IGF-I was lowered 24% by DR but was completely restored in the IGF-I/DR-treated mice using recombinant IGF-I administered via osmotic minipumps. Although tumor progression was decreased by DR, restoration of IGF-I serum levels in DR-treated mice increased the stage of the cancers. Furthermore, IGF-I modulated tumor progression independent of changes in body weight. Rates of apoptosis in the preneoplastic lesions were 10 times higher in DR-treated mice compared to those in IGF/DR- and ad libitum-treated mice.

Inhibition of SERCA2b impairs UCP1-independent beige fat thermogenesis in humans and mice as well as in pigs, a species that lacks a functional UCP1 protein. Conversely, enhanced Ca2+ cycling by activation of α1- and/or β3-adrenergic receptors or the SERCA2b-RyR2 pathway stimulates UCP1-independent thermogenesis in beige adipocytes. In the absence of UCP1, beige fat dynamically expends glucose through enhanced glycolysis, tricarboxylic acid metabolism and pyruvate dehydrogenase activity for ATP-dependent thermogenesis through the SERCA2b pathway; beige fat thereby functions as a 'glucose sink' and improves glucose tolerance independently of body weight loss.

RESULTS Chow-reared IL-18 knockout mice were overweight at 6 months of age and then gained excess weight on both low-fat and high-fat diets, ate more high-fat diet, and showed reduced whole-body energy expenditure and increased respiratory exchange ratios. Reductions in energy expenditure of IL-18 knockout mice were seen across fasting vs. feeding conditions, low- vs. high-fat diets, high vs. low levels of physical activity and times of day, suggesting actions on basal metabolic rate.

The ability of adipose tissue expansion in the offspring of obese mothers is limited and is associated with metabolic dysfunction of adipose tissue when challenged with a high-fat diet. Maternal obesity induces DNA demethylation in the promoter of zinc finger protein 423, which renders progenitor cells with a high adipogenic capacity. Maternal obesity demonstrates long-term effects on the adipogenic capacity of progenitor cells in offspring adipose tissue, demonstrating a developmental programming effect. ABSTRACT Maternal obesity (MO) programs offspring obesity and metabolic disorders, although the underlying mechanisms remain poorly defined. Progenitor cells are the source of new adipocytes. The present study aimed to test whether MO epigenetically predisposes adipocyte progenitors in the fat of offspring to adipogenic differentiation and subsequent depletion, which leads to a failure of adipose tissue plasticity under positive energy balance, contributing to adipose tissue metabolic dysfunction. C57BL/6 female mice were fed either a control diet (10% energy from fat) or a high-fat diet (45% energy from fat) for 8 weeks before mating. Male offspring of control (Con) and obese (OB) dams were weaned onto a regular (Reg) or obesogenic (Obe) diet until 3 months of age. At weaning, male OB offspring had a higher expression of Zinc finger protein 423 (zfp423), a key transcription factor in adipogenesis, as well as lower DNA methylation of its promoter in progenitors of epididymal fat compared to Con offspring, which was correlated with enhanced adipogenic differentiation. At 3 months of age, progenitor density was 30.9 ± 9.7% lower in OB/Obe compared to Con/Obe mice, accompanied by a limited expansion of the adipocyte number when challenged with a high-energy diet. This difference was associated with lower DNA methylation in the zfp423 promoter in the epididymal fat of OB/Obe offspring, which was correlated with greater macrophage chemotactic protein-1 and hypoxia-inducible factor 1α expression. In summary, MO epigenetically limits the expansion capacity of offspring adipose tissue, providing an explanation for the adipose metabolic dysfunction of male offspring in the setting of MO.", "title": "Maternal obesity epigenetically alters visceral fat progenitor cell properties in male offspring mice." }, { "docid": "12805683", "text": "Mammalian nuclear hormone receptors (NHRs), such as liver X receptor, farnesoid X receptor, and peroxisome proliferator-activated receptors (PPARs), precisely control energy metabolism.

Here we show that deletion of the Caenorhabditis elegans NHR gene nhr-49 yielded worms with elevated fat content and shortened life span. Employing a quantitative RT-PCR screen, we found that nhr-49 influenced the expression of 13 genes involved in energy metabolism. Indeed, nhr-49 served as a key regulator of fat usage, modulating pathways that control the consumption of fat and maintain a normal balance of fatty acid saturation. We found that the two phenotypes of the nhr-49 knockout were linked to distinct pathways and were separable: The high-fat phenotype was due to reduced expression of enzymes in fatty acid β-oxidation, and the shortened adult life span resulted from impaired expression of a stearoyl-CoA desaturase. Despite its sequence relationship with the mammalian hepatocyte nuclear factor 4 receptor, the biological activities of nhr-49 were most similar to those of the mammalian PPARs, implying an evolutionarily conserved role for NHRs in modulating fat consumption and composition.

In animal models, obese mice with fatty livers are vulnerable to liver adenosine triphosphate (ATP) depletion and necrosis, suggesting that altered hepatic energy homeostasis may be involved. OBJECTIVE To determine if patients with fatty liver disease exhibit impaired recovery from hepatic ATP depletion. DESIGN Laboratory analysis of liver ATP stores monitored by nuclear magnetic resonance spectroscopy before and after transient hepatic ATP depletion was induced by fructose injection. The study was conducted between July 15 and August 30, 1998. SETTING University hospital. PATIENTS Eight consecutive adults with biopsy-proven nonalcoholic steatohepatitis and 7 healthy age- and sex-matched controls. MAIN OUTCOME MEASURE Level of ATP 1 hour after fructose infusion in patients vs controls. RESULTS In patients, serum aminotransferase levels were increased (P = .02 vs controls); albumin and bilirubin values were normal and clinical evidence of portal hypertension was absent in both groups. However, 2 patients had moderate fibrosis and 1 had cirrhosis on liver biopsy. Mean serum glucose, cholesterol, and triglyceride levels were similar between groups but patients weighed significantly more than controls (P = .02). Liver ATP levels were similar in the 2 groups before fructose infusion and decreased similarly in both after fructose infusion (P = .01 vs initial ATP levels). However, controls replenished their hepatic ATP stores during the 1-hour follow-up period (P<.02 vs minimum ATP) but patients did not. Hence, patients' hepatic ATP levels were lower than those of controls at the end of the study (P = .04). Body mass index (BMI) correlated inversely with ATP recovery, even in controls (R = -0.768; P = .07). Although BMI was greater in patients than controls (P = .02) and correlated strongly with fatty liver and serum aminotransferase elevations, neither of the latter 2 parameters nor the histologic severity of fibrosis strongly predicted hepatic ATP recovery.

[ { "docid": "69197", "text": "Quote driven markets are the predecessors to the modern securities market. Before electronic trading and HFTs specifically, trading was thin and onerous. Today, the average investor can open up a web page, type in a security, and buy at the narrowest spread permitted by regulators with anyone else who wants to take the other side. Before the lines between market maker and speculator became blurred to indistinction, a market maker was one who was contractually obligated to an exchange to provide a bid and ask for a given security on said exchange even though at heart a market maker is still simply a trader despite the obligation. A market maker would simultaneously buy a large amount of securities privately and short the same amount to have no directional bias, exposure to the direction of the security, and commence to making the market. The market maker would estimate its cost basis for the security based upon those initial trades and provide a bid and ask appropriate for the given level of volume. If volumes were high, the spread would be low and vice versa. Market makers who survived crashes and spikes would forgo the potential profit in always providing a steady price and spread, ie increased volume otherwise known as revenue, to maintain no directional bias. In other words, if there were suddenly many buyers and no sellers, hitting the market maker's ask, the MM would raise the ask rapidly in proportion to the increased exposure while leaving the bid somewhere below the cost basis. Eventually, a seller would arise and hit the MM's bid, bringing the market maker's inventory back into balance, and narrowing the spread that particular MM could provide since a responsible MM's ask could rise very high very quickly if a lack of its volume relative to its inventory made inventory too costly. This was temporarily extremely costly to the trader if there were few market makers on the security the trader was trading or already exposed to. Market makers prefer to profit from the spread, bidding below some predetermined price, based upon the cost basis of the market maker's inventory, while asking above that same predetermined cost basis. Traders profit from taking exposure to a security's direction or lack thereof in the case of some options traders. Because of electronic trading, liquidity rebates offered by exchanges not only to contractually obligated official market makers but also to any trader who posts a limit order that another trader hits, and algorithms that become better by the day, market making HFTs have supplanted the traditional market maker, and there are many HFTs where there previously were few official market makers. This speed and diversification of risk across many many algorithmically market making HFTs have kept spreads to the minimum on large equities and have reduced the same for the smallest equities on major exchanges. Orders and quotes are essentially identical. Both are double sided auction markets with impermenant bids and asks. The difference lies in that non-market makers, specialists, etc. orders are not shown to the rest of the market, providing an informational advantage to MMs and an informational disadvantage to the trader. Before electronic trading, this construct was of no consequence since trader orders were infrequent. With the prevalence of HFTs, the informational disadvantage has become more costly, so order driven markets now prevail with much lower spreads and accelerated volumes even though market share for the major exchanges has dropped rapidly and hyperaccelerated number of trades even though the size of individual trades have fallen. The worst aspect of the quote driven market was that traders could not directly trade with each other, so all trades had to go between a market maker, specialist, etc. While this may seem to have increased cost to a trader who could only trade with another trader by being arbitraged by a MM et al, paying more than what another trader was willing to sell, these costs were dwarfed by the potential absence of those market makers. Without a bid or ask at any given time, there could be no trade, so the costs were momentarily infinite. In essence, a quote driven market protects market makers from the competition of traders. While necessary in the days where paper receipts were carted from brokerage to brokerage, and the trader did not dedicate itself to round the clock trading, it has no place in a computerized market.

The NYSE has \"\"specialists\"\" that are market makers that also performed a few other roles in the management of trading for a stock, and usually a single issue on the NYSE is covered by only one market maker. Market makers are often middlemen between brokers (ignoring stuff like dark pools, and the fact that brokers will often trade stocks internally among their own clients before going to the exchange). Historically, the market makers gave up buy/sell discretion in exchange for being the \"\"go-to guys\"\" for anyone wanting to trade in that stock. When you told your broker to buy a stock for you, he didn't hook you up with another retail investor; he went to the market maker.

They were like other floor traders; they hung out on the exchange floors and interacted with traders to buy and sell stocks. Traders came to them when they wanted to buy one of the specialist's issues. There was no public order book; just ticker tape and a quote. It was up to the market maker to maintain that order book.

Because they build that cost into the quotes they give you. In sleepy markets, buyers and sellers cancel out, they just \"\"capture\"\" that spread which is the desired outcome when that business model functions well. There are two situations where the brokerage's might lose money and capital becomes very important. In extremely volatile markets, every one of their clients may want to sell for some reason, this forces the FX brokers to accumulate a large position in the opposite side that they have to offload. They will trade in the institutional market with other brokerages to net out their positions so that they are as close to flat as possible. In the process, since bid/ask spreads in the institutional market is tighter than within their own brokerage by design, they should still make money while not taking much risk. However, if they are not fast enough, or if they do not have enough capital, the brokerage's position might move against them too quickly which may cause them lose all their capital and go belly up. The brokerage is net flat, but there are huge offsetting positions amongst its clients. In the example of the Swiss Franc revaluation in early 2015, a sudden pop of 10-20% would have effectively meant that money in client accounts that were on the wrong side of the trade could not cover those on the other side. When this happens, it is theoretically the brokerage's job to close out these positions before it wipes out the value of the client accounts, however it would have been impossible to do so since there were no prices in between the instantaneous pop in which the brokerage could have terminated their client's losing positions, and offload the risk in the institutional market. Since it's extremely hard to ask for more money than exist in the client accounts, those with strong capital positions simply ate the loss (such as Oanda), those that fared worse went belly up. The irony here is that the more leverage the brokerage gave to their clients, the less money would have been available to cover losses in such an event. Using an example to illustrate: say client A is long 1 contract at $100 and client B is short 1 contract at $100. The brokerage is thus net flat. If the brokerage had given 10:1 leverage, then there would be $10 in each client's account. Now instantaneously market moves down $10. Client A loses $10 and client B is up $10. Brokerage simply closes client A's position, gives $10 to client B. The brokerage is still long against client B however, so now it has to go into the institutional market to be short 1 contract at $90. The brokerage again is net flat, and no money actually goes in or out of the firm. Had the brokerage given 50:1 leverage however, client A only has $2 in the account. This would cause the brokerage close client A's position. The brokerage is still long against client B, but has only $2 and would have to \"\"eat the loss\"\" for $8 to honor client B's position, and if it could not do that, then it technically became insolvent since it owes more money to its clients than it has in assets. This is exactly the reason there have been regulations in the US to limit the amount of leverage FX brokerages are allowed to offer to clients, to assure the brokerage has enough capital to pay what is owed to clients.\"", "title": "" }, { "docid": "417365", "text": "\"First, as @littleadv mentions, and as I've pointed out before, anyone who participates in a market using limit orders (which, by the way, should be every non-professional investor) is by definition a market maker. So, I will assume that your question pertains both to official market makers and to \"\"retail investors\"\" using limit orders. When you remark that there are such \"\"tight spreads\"\" in \"\"liquid assets\"\", what you are really saying is \"\"wow, look at all the market makers in these products!\"\" That's the benefit of electronic trading and algorithmic traders -- millions of participants each with their own opinion of the value of a financial instrument, trying to find people who have very specifically opposing opinions of the value of that same instrument. This is called price discovery, and is the entire point of financial markets. So, you ask why are there all these market makers present to create such tight spreads in assets like SPY? Answer: Because they can make money in these markets: Imagine (towards a contradiction) that market makers thought they couldn't make money by offering tight spreads in SPY, and so SPY had a wider spread than it actually does. For example, say the highest bid for SPY was $99.98 and the lowest ask was $100.01. Now imagine that a market maker with perfect knowledge of the future came along knowing that he would be able to sell SPY for $100.01 in 5 minutes. Then he would load up as many buy orders as he could for $100.00 or lower. (He wouldn't bid $100.01 or higher because those trades would not be profitable according to his information -- at least not 5 minutes from now.) So the spread had previously been $0.03 and then suddenly it was $0.01, all because a market maker with better information came along and realized he could make money by creating a tighter market! Now, nobody has perfect knowledge of the future, which is why markets are never infinitely tight or infinitely liquid. Each market maker has to weigh possible profits against the probability that those profits will actually turn into losses. But if one market maker decides not to participate in a particular instrument, there's bound to be another market maker who will happily take his place. So the very fact that there are so many market participants with resting buy/sell orders for SPY right now is proof that there are market makers able to make money doing so. If they could not make money, they wouldn't be there, and the spread would be wider. 10-15 years ago, before electronic trading and algorithmic trading, the number of market participants was far lower, and the spreads were far wider, meaning retail investors like you and me had a much harder time making money. The only people making money were the institutional investors, the brokers, and the exchanges. Now that all these new millions of players are present in the market, retail investors like you and me get to participate and make money too.\"", "title": "" }, { "docid": "159822", "text": "\"ETFs are well suited to day trading, but you should be mindful of the bid-ask spread.

When a market trades at the bid, this means that a sell market order has interacted with a buy limit order at the limit price. An ordinary investor can do exactly the same as a market maker and submit limit orders. Furthermore, they can sit on both sides of the bid and ask exactly as a market maker does.

An order executes ONLY when both bid and ask meet. (bid = ask) This is completely incorrect. A transaction occurs when an active (marketable) order is matched with a passive (limit book) order. If the passive order is a sell limit then the trade has occurred at the ask, and if it is a buy limit the trade has occurred at the bid. The active orders are not bids and asks.

So maybe we could use some measure of the volume at various price levels in each of the bid/ask books to decide some notion of net buying/selling.

I mean if you have an open order for more than 10 times the amount currently offered with a limit above the offer, and you havent gotten filled on the bid, what can you do but lift the offer and try to be first at the next price level up? At least you would have gotten some at the price they quoted, or are they fill or kill? &gt; \"\"Bidding it up to attract sellers\"\" sounds an awful lot like spoofing, just a heads up. Sure though, if you want to tighten a spread or create new levels with aggressive passive liquidity, that is a strategy. The same caveats as I mentioned above apply. Just to be clear, 'aggressively adding passive liquidity' is the more apt way to put it - I'm talking about when you actually want to get filled on those bids but you're having trouble finding sellers. Could you give me an example of what you might consider passive or aggressive, just for scale - would a mkt impact of .10% raise any eyebrows? How do you gauge fair value or does that matter less to you than just accumulating/selling what you can for what you were asked to? &gt; Anyway, if market impact isn't an issue for the customer, sure, take liquidity until you're filled. Don't forget about getting good size done in the opening and closing auctions (MOO/MOC). If you're too passive you risk the market moving away from you and pissing off the customer. If you're too aggressive you risk moving the market too much and pissing off the customer. So then is the question more 'how motivated is the buyer or seller?'

They provide a way for investors to get broad exposure in a real estate market without going to buy a bunch of properties themselves. It also provides diversification within the real estate segment since REITs will often (but not necessarily) have either way more properties than an individual could get or have very large properties (like a few resorts) that would be too expensive for any one investor.

Some of those dividends may be tax advantaged and some will not. An MLP is a master limited partnership. These trade on the exchange like corporations, but they are not corporations. (Although often used in common language as synonyms, corporation and company are not the same thing. Corporation is one way to organize a company under the law.) They are partnerships, and when you buy a share you become a partner in the company. This is an alternative form of ownership to being a shareholding. In this case you are a limited partner, which means that you have limited liability as with stock. The shares may appreciate or not, just like a stock, and you can generally sell them back to the market for a capital gain or loss under the same rules as a stock. The main difference here from a practical point of view is taxes: Partnerships (of any type) do no pay tax - Instead their income and costs are passed to the individual partners, who must then include it on their personal returns (Form 1040, Schedule E). The partnership will send each shareholder a Schedule K-1 form at tax time. This means you may have \"\"phantom income\"\" that is taxable even though cash never flowed through your hands since you'll have to account for the income of the partnership. Many partnerships mitigate this by making cash distributions during the year so that the partners do actually see the cash, but this is not required. On the other hand, if it does happen, it's often characterized as a return of capital, which is not taxable in the year that you receive it. A return of capital reduces your cost basis in the partnership and will eventually result in a larger capital gain when you sell your shares. As with any investment, there are pros and cons to each investment type. Of the two, the MLP is probably less like a \"\"regular\"\" stock since getting the Schedule K-1 may require some extra work at tax time, especially if you've never seen one before. On the other hand, that may be worth it to you if you can find one that's appreciating in value and still returning capital at a good rate since this could be a \"\"best of everything\"\" situation where you defer tax and - when you eventually do pay, you pay at favorable capital gains rates - but still manage to get your cash back in hand before you sell.

So what you can do is, you can go through all the existing real estate funds and find out if any of them has a broker that let's you short it, in other words which one of them has securities in the financial market you can buy or sell. One other option is looking for real estate/property derivatives, like this particular example. Personally, I would try to computationally find other securities that may in some way correlate with the real estate market, even if they look a bit far fetched to be related like commodities and stock from companies in construction and real estate management, etc. and trade those because these have in most of the cases more liquidity.

That would permit you to invest directly in a property via your IRA/401K money without it being a loan, and preserving the tax benefits. (You may not be able to roll over from your current employer's 401K while still employed.) That said, regarding your argument that your loan is \"\"paying interest to yourself\"\", while that is technically true, that neglects the opportunity cost -- that money could potentially be earning a much higher (and tax-free) return if it remains in the 401K account than if you take it out and slowly repay it at a modest interest rate. Real Estate can be a great way to diversify, build wealth, and generate income, but a company match and tax-free growth via an employee sponsored retirement account can be a pretty sweet deal too (I actually recently wrote about comparing returns from having a tenant pay your mortgage on a rental property vs. saving in a retirement account on my blog -- in short, tax-free stock-market level returns are pretty compelling, even when someone else is paying your mortage). Before taking rather big steps like borrowing from a 401K or buying a rental property, you might also explore other ways to gain some experience with real estate investing, such as the new crop of REITs open to all investors under SEC Reg A+, some with minimums of $500 or less. In my own experience, there are two main camps of real estate investors: (1) those that love the diversification and income, but have zero interest in active management, and (2) those that really enjoy real estate as a lifestyle and avocation, happy to deal with tenant screening and contractors, etc. You'll want to be careful to be sure which camp you're in before signing on to active investment in a specific property.\"", "title": "" }, { "docid": "332064", "text": "It looks like you need a lot more education on the subject.

It's possible to buy both badly, and in the case of stocks, there are studies that show the typical investor lags the market by many percent. Real estate is not a homogeneous asset class. A $200K house renting for $1,000 is a far different investment than a $100K 3 family renting for $2,000 total rents. Both exist depending on the part of the country you are in. If you simply divide the price to the rent you get either 16.7X or 4.2X. This is an oversimplification, and of course, interest rates will push these numbers in one direction or another. It's safe to say that at any given time, the ratio can help determine if home prices are too high, a bargain, or somewhere in between. As one article suggests, the median price tracks inflation pretty closely. And I'd add, that median home prices would track median income long term. To circle back, yes, real estate can be a good investment if you buy right, find good tenants, and are willing to put in the time. Note: Buying to rent and buying to live in are not always the same economic decision. The home buyer will very often buy a larger house than they should, and turn their own 'profit' into a loss. e.g. A buyer who would otherwise be advised to buy the $150K house instead of renting is talked into a bigger house by the real estate agent, the bank, the spouse.

Below are some of my thoughts on the questions that you have put forward. 1) The investment manager question: The returns on your capital for a half year has been quite low; having said that, some investments do take more than half year to show some growth. You could try talking to your investment manager and ask where your money has been deployed and why the returns are low. If there are no real explanation given forth (which would be more likely as you have mentioned your investment manager does not like to discuss your money with you) you should conside Xolorus & Pete's advice and forthwith take all your money from investment manager and park it in the bank till you figure out what to do next with it. 2) Finances are not my forte: At 22 finance is nobodies forte, it takes longer than that; however having said that, how do you know finance is actually not your forte? Being a computer science graduate you would be more than comfortable with the mathematics required for finance. You may not have looked seriously at finance till now (I assume by your statement). Once way to be certain about this would be self learning, some good books have been refered above and there are online information, courses and articles on the Internet, for example here. You could give some spare time and explore if finance interests you or not. 3) If finance interests you: Then consider the 30K as your seed fund and take a small portion of it say 2K and try out your hand at investing on your own in the instruments that you feel most comfortable and see how you fare, you are young enough to take the risk. Rest of the money you could put in other low risk instruments (that you have identified through self study) 4) If finance does not interest you: The probably you are better off with an investment manager, as observed above, it will take some time for you to identify him/her 5) On returns: As mentioned above different instruments produce returns differently, however, one question that is universally asked is how much return on an invetment shoule one expect (you were expecting more than $12 on your investment). It is a difficult question to answer as invetment returns and investment needs depend on a persons financial goals and risk taking profile.

You're able to hold them in a tax-advantaged account and not pay taxes on the income until you withdraw it from the account (or tax free in the case of a Roth account.)

Why?\"\" For the cash in an estate, yes, that is after-tax money, but consider other assets such as stocks and real estate. Suppose a rich man bought stock in a small computer start-up company at $10 a share about 35 years ago, and that stock is now worth $500 a share. The man dies and his will bequeaths the shares to his son. According to US tax law, the son's basis in the shares is $500 per share, that is, if the son sells the shares, his capital gains are computed as if he had purchased the shares for $500 each. The son pays no taxes on the inheritance he receives. The deceased father's last income tax return (filed by the executor of the father's will) does not list the $490/share gain as a capital gain since the father did not sell the stock (the gain is what is called an unrealized gain), and so there is no income tax due from the father on the $490/share. Now, if there is no estate tax whatsoever, the father's estate tax return pays no tax on that gain of $490 per share either. Would this be considered an equitable system? Should the government not tax the gain at all? It is worth noting that it would be possible for a government to eliminate estate taxes entirely, but instead have tax laws that say that unrealized gains on the deceased's property would be taxed (as capital gains) on the deceased's final tax return.\"", "title": "" }, { "docid": "57960", "text": "Apples and oranges.

Buy Php in Malaysia and sell to Philippines

The Unit is generally constant. These are only revised when there is large devaluation of a particular currency. Buying Php for MYR 8.52, Selling MYR 8.98. So in this case the Unit of PHP is 100, so Bank is Buying 100 PHP from you [you are selling PHP] and will give you MYR 8.52. If you now want to buy 100 PHP [so the Bank is selling you], you have to pay MYR 8.98. So you loose MYR 0.46 Why are they selling it way beyond the exchange rate? Why is this? As explained above, they are not. Its still within the range. The quote on internet are average price. This means before going back to Philippines, I can buy a lot of peso that I can buy and exchange it for higher price right? Generally an individual cannot make money by buying in one currency and selling in other. There are specialist who try and find arbitrage between multiple pair of currencies and make money out of it.

For example, in the Philippines, the lowest fee charged still involves waiting 30 days to get your money. Specifically, I opened a US dollar savings account with the minimum of US $500 required (other rules are involved for opening a bank account), deposited a personal check drawn on my US bank account (no fee charged), and waited 30 calendar days to withdraw USD bills. The Philippines bank did not have a branch in the US, but had financial arrangements with US banks. After getting USD dollars in my hand, I walked to a nearby exchange business store (which usually offered a better daily rate than a bank, but a rate between the banks' buy and sell rates) and exchange the dollars for pesos. Note that years ago, banks did not give USD bills, when dollars were scarce in the Philippines.

You'll need to learn a compiled language and how to scale data storage if you want to code for finance. I would suggest you learn C# or Java if you really want a decent gig programming in the finance industry. Anybody using PHP and API's to trade isn't somebody you want to work for. It will cause way more headaches than it's worth and you miss opportunities due to speed and efficiency of a language like PHP. You will hit a wall with it at some point (some problem/bug/whatever that can't be solved), and it will really bring you down when you realize it has to be re-done in another language. That being said, PHP is great for the front end (showing people the data and letting them search etc), but the core of it that grabs stats and does the calculations should be in a compiled language. PHP can also be used to quickly test ideas to see if it's worth building a full system that will scale. Basically a rough draft of the program to see if it's going to work out. Why? Well in PHP you can get things done very quickly with very little code because a large amount of libraries and functions exist and it's a very easy language to understand. But it's not efficient, and that's why you create the real deal program using C, C#, or java, or whatever. Scalability of data storage will be important to. You'll need to store a ton of information and you'll need to be able to sort/change/remove/add it quickly. Many databases already exist to do this and I see you know MySQL already a good bit. You'll need to get very familiar with it because the database is going to be your biggest bottleneck in terms of speed. It doesn't matter how well your software works if the database is taking 5 seconds to return a query. Learn to tweak MySQL, learn about MSSQL, look into Firebird. Also learn about at least one NoSQL storage solution (these databases can store a massive amount of information, but they work differently than a sql database does). I would recommend learning MongoDB if you already know PHP. It is a good transition from SQL style databases to Key Storage databases.

This will allow you to earn a return (the premium from the calls) without necessarily having to give up your holding. As a brief overview, \"\"options\"\" are derivatives that give the holder the right (or option) to buy or sell shares at a specified price. Holders of call options with a strike prike $x on a particular security have the right to purchase that security at the strike price $x. Conversely, holders of put options with a strike price of $x have the right to sell that security at the strike price $x. Always on the other side of a call or put option is a person that has sold the option, which is called \"\"writing\"\" the option. If this person writes a call option, then he will be obligated to sell a certain amount of stock (100 shares per contract) at the strike price if that option is exercised. A writer of a put option will be obligated to by 100 shares per contract at the strike price if that option is exercised. Covered calls involve writing call contracts on stock that you own. For example, say you own 100 shares of AAPL, and that AAPL is currently trading for $330. You decide to write a Jan 21, 2012 call on these shares at a strike price of $340, earning you a premium of say $300. Two things can now happen: if the price of AAPL is not at least $340 on January 21, then the options are \"\"out of the money\"\" and will expire unexercised (why exercise an option to buy at $340 when you can buy at the currently cheaper market price?). You keep your AAPL stock plus the $300 premium you earn. If, however, the price of AAPL is greater than $340, the option will be exercised and you will now be required to sell the shares you own at $340. You will earn a return of $10/share ($340-$330), plus the $300 premium from the call option. You still make out in the end, but have unfortunately incurred an opportunity cost, as had you not written the call option you would have been able to sell at the market price, which is higher than the $340 strike price. Covered calls are considered relatively safe and conservative, however the strategy is most effective for stocks that are expected to stay within a relatively narrow price range for the duration of the contract.

While it appears that the COO has performed a buy and a sell on the same day, most people would consider this a 'single trade'. In reality, it seems that the COO had 'stock options' [a contract providing the option for the holder to buy stock at a specific price, at some point in the future], provided as part of his compensation package. He decided or was required to 'exercise' those options today. This means he bought the shares using his special 'option price'. It is extremely common for employees who exercise stock options, to sell all of the resulting stock immediately. This is very different from usual day-trading, which implies that he would have bought stock in the morning at a low price, and then sold it later at a high price. You are calling this 'insider trading'. That term specifically often implies some level of unethical behavior. In general, stock options offered to executive employees are strictly limited in how they can be exercised. For example, most stock option plans require employees to wait x number of years before they can exercise them. This gives the employee incentive to stay longer, and for a high-level executive with the ability to strongly impact company performance, it gives incentive to do well. Technically you are correct, this is likely considered an 'insider trade', but given that it seems to have been a stock option exercise, it does not necessarily imply that there was any special reasoning for why he did the trade today.

The only risk in taking a covered call position is that you will be required to sell your shares for less than the going market price. I don't entirely agree with the accepted answer given here. You would not lose the amount you paid to buy the shares. Naked Call Option Suppose take a naked call option position by selling a call option. Since there is no limit on how high the price of the underlying share can go, you can be forced to either buy back the option at a very high price, or, in the case that the option is exercised, you can be force. to buy the underlying shares at a very high price and then sell them to the option holder at a very low price. For example, suppose you sell an Apple call option with a strike price of $100 at a premium of $2.50, and for this you receive a payment of $250. Now, if the price of Apple skyrockets to, say, $1000, then you would either have to buy back the option for about $90,000 = 100 x ($1000-$100), or, if the holder exercised the option, then you would need to buy 100 Apple shares at the market price of $1000 per share, costing you $100,000, and then sell them to the option holder at the strike price of $100 for $10,000 = 100 x $100. In either case, you would show a loss of $90,000 on the share transaction, which would be slightly offset by a $250 credit for the premium you received selling the call. There is no limit on the potential loss since there is no limit on how high the underlying share price can go. Covered Call Option Consider now the case of a covered call option. Since you hold the underlying shares, any loss you make on the option position would be \"\"covered\"\" by the profit you make on the underlying shares. Again, suppose you own 100 Apple shares and sell a call option with a strike price of $100 at a premium of $2.50 to earn a payment of $250. If the price of Apple skyrockets to $1000, then there are again two possible scenarios. One, you buy back the option at a premium of about $900 costing you $90,000. In order to cover this cost you would then sell your 100 Apple shares at the market price of $1000 per share to realise $100,000 = 100 x $1000. On the other hand, if your option is exercised, then you would deliver your 100 Apple shares to the option holder at the contracted strike price of $100 per share, thus receiving just $10,000 = 100 x $100.

I'll assume you are referring to publicly traded stock options, such as those found on the CBOE, and not an option contract entered into privately between two specific counterparties (e.g. as in an employer stock option plan). Since you are not obligated to exercise a call option you purchased on the market, you don't need to maintain funds on account for possible exercising. You could instead let the option expire, or resell the option, neither of which requires funds available for purchase of the underlying shares. However, should you actually choose to exercise the call option (and usually this is done close to expiration, if at all), you will be required to fund your account much like if you bought the underlying shares in the first place. Call your broker to determine the exact rules and timing for when they need the money for a call-option exercise. And to expand on the idea of \"\"cancelling\"\" an option you purchased: No, you cannot \"\"cancel\"\" an option contract, per se. But, you are permitted to sell the call option to somebody else willing to buy, via the market. When you sell your call option, you'll either make or lose money on the sale – depending on the price of the underlying shares at the time (are they in- or out- of the money?), volatility in the market, and remaining time value. Once you sell, you're back to \"\"no position\"\". That's not the same as \"\"cancelled\"\", but you are out of the trade, whether at profit or loss. Furthermore, the option writer (i.e. the seller who \"\"sold to open\"\" a position, in writing the call in the first place) is also not permitted to cancel the option he wrote. However, the option writer is permitted to close out the original short position by simply buying back a matching call option on the market. Again, this would occur at either profit or loss based on market prices at the time. This second kind of buy order – i.e. made by someone who initially wrote a call option – is called a \"\"buy to close\"\", meaning the purchase of an offsetting position. (The other kind of buy is the \"\"buy to open\"\".) Then, consider: Since an option buyer is free to re-sell the option purchased, and since an option writer (who \"\"sold to open\"\" the new contract) is also free to buy back an offsetting option, a process known as clearing is required to match remaining buyers exercising the call options held with the remaining option writers having open short positions for the contract. For CBOE options, this clearing is performed by the Options Clearing Corporation. Here's how it works (see here): What is the OCC? The Options Clearing Corporation is the sole issuer of all securities options listed at the CBOE, four other U.S. stock exchanges and the National Association of Securities Dealers, Inc. (NASD), and is the entity through which all CBOE option transactions are ultimately cleared. As the issuer of all options, OCC essentially takes the opposite side of every option traded. Because OCC basically becomes the buyer for every seller and the seller for every buyer, it allows options traders to buy and sell in a secondary market without having to find the original opposite party. [...]   [emphasis above is mine] When a call option writer must deliver shares to a call option buyer exercising a call, it's called assignment. (I have been assigned before, and it isn't pleasant to see a position called away that otherwise would have been very profitable if the call weren't written in the first place!) Also, re: \"\"I know my counter party cannot sell his shares\"\" ... that's not strictly true. You are thinking of a covered call. But, an option writer doesn't necessarily need to own the underlying shares. Look up Naked call (Wikipedia). Naked calls aren't frequently undertaken because a naked call \"\"is one of the riskiest options strategies because it carries unlimited risk\"\".

Some companies offer stock options that vest over a number of years, but which can be exercised before they are vested. That is early exercise. You have vested stock options, so early exercise is not relevant. (It may or may not be the case that your stock options could have been early exercised before they vested, but regardless, you didn't exercise them, so the point is moot.) As littleadv said, 83(b) election is for restricted stocks, often from exercising unvested stock options. Your options are already vested, so they won't be restricted stock. So 83(b) election is not relevant for you. A taxable event happen when you exercise. The point of the 83(b) election is that exercising unvested stock options is not a taxable event, so 83(b) election allows you to force it to be a taxable event. But for you, with vested stock options, there is no need to do this. You mention that you want it not to be taxable upon exercise. But that's what Incentive Stock Options (ISOs) are for. ISOs were designed for the purpose of not being taxable for regular income tax purposes when you exercise (although it is still taxable upon exercise for AMT purposes), and it is only taxed when you sell. However, you have Non-qualified Stock Options. Were you given the option to get ISOs at the beginning? Why did your company give you NQSOs? I don't know the specifics of your situation, but since you mentioned \"\"early exercise\"\" and 83(b) elections, I have a hypothesis as to what might have happened. For people who early-exercise (for plans that allow early-exercise), there is a slight advantage to having NQSOs compared to ISOs. This is because if you early exercise immediately upon grant and do 83(b) election, you pay no taxes upon exercise (because the difference between strike price and FMV is 0), and there are no taxes upon vesting (for regular or AMT), and if you hold it for at least 1 year, upon sale it will be long-term capital gains. On the other hand, for ISOs, it's the same except that for long-term capital gains, you have to hold it 2 years after grant and 1 year after exercise, so the period for long-term capital gains is longer. So companies that allow early exercise will often offer employees either NQSOs or ISOs, where you would choose NQSO if you intend to early-exercise, or ISO otherwise. If (hypothetically) that's what happened, then you chose wrong because you got NQSOs and didn't early exercise.\"", "title": "" }, { "docid": "345410", "text": "The crucial insight is that the alternative to early exercise of an American call is not necessarily to hold it to expiry, but to sell it.

We know that at expiry T, we have (using a Call and a Put both struck at K): C(T) - P(T) = S(T) - K (if this is not clear to you, consider the case where S is less than, equal to, or greater than K at maturity, and go through each of them.) If the stock S doesn't pay any dividends (and there is no cost of carry etc.), we can replicate both sides now at time 0; we just buy one call, sell one put (that gives us the left hand side), buy the stock, and borrow money so that at time T we have to repay K (that gives us the right hand side).

You make money if neither is exercised (you keep the premium you sold for) or both are exercised (you keep the gap between the two, plus the premium). Having both exercised is surely rare, since early exercise is rare to begin with, and tends to happen when options are deep in the money; so you'd expect both to be exercised if both are deep in the money at some point.

The other replies do not appear to address this situation. Suppose that Apple is trading at $96 and you sell a put option with a strike price of $95 for some future delivery date - say August 2016. The option contract is for 100 shares and you sell the contract for a premium of $3.20. When you sell the option your account will be credited with the premium and debited with the broker commission. The premium you receive will be $320 = 100 x $3.20. The commission you pay will depend on you broker. Now suppose that the price of Apple drops to $90 and your option is exercised, either on expiry or prior to expiry. Then you would be obliged to take delivery of 100 Apple shares at the contracted option strike price of $95 costing you $9,500 plus broker commission. If you immediately sell the Apple shares you have purchased under your contract obligations, then assuming you sell the shares at the current market price of $90 you would realise a loss of $500 ( = 100x($95-$90) )plus commission. Since you received a premium of $320 when you sold the put option, your net loss would be $500-$320 = $180 plus any commissions paid to your broker. Now let's look at the case of selling a call option. Again assume that the price of Apple is $96 and you sell a call option for 100 shares with a strike price of $97 for a premium of $3.60. The premium you receive would be $360 = 100 x $3.60. You would also be debited for commission by your broker. Now suppose that the price of Apple shares rises to $101 and your option is exercised. Then you would be obliged to deliver 100 Apple shares to the party exercising the option at the contracted strike price of $97. If you did not own the shares to effect delivery, then you would need to purchase those shares in the market at the current market price of $101, and then sell them to the party exercising the option at the strike price of $97. This would realise an immediate loss of $400 = 100 x ($101-$97) plus any commission payable. If you did own the shares, then you would simply deliver them and possibly pay some commission or a delivery fee to your broker. Since you received $360 when you sold the option, your net loss would be $40 = $400-$360 plus any commission and fees payable to the broker.

Both contract types have both common sides of a transaction, a buyer and a seller. You can sell a put contract, or sell a call contract also; you're just taking the other side of the agreement. If you're selling it would commonly be called a \"\"sell to open\"\" meaning you're opening your position by selling a contract which is different from simply selling an option that you currently own to close your position. A put contract gives the buyer the right to sell shares (or some asset/commodity) for a specified price on a specified date; the buyer of the contract gets to put the shares on someone else. A call contract gives the buyer the right to buy shares (or some asset/commodity) for a specified price on a specified date; the buyer of the contract gets to call on someone for shares. \"\"American\"\" options contracts allow the buyer can exercise their rights under the contract on or before the expiration date; while \"\"European\"\" type contracts can only be exercised on the expiration date.

You would exercise for $10,000 ($100 times 100 shares), then sell the shares for $10 profit per share; less the cost of the contract and transaction costs. Option 2: Your contract is now worth something closer to $10 per share, up from $1 per share when you bought it.

The gain or loss is long term or short term depending on your holding period of the stock. https://www.irs.gov/publications/p550/ch04.html#en_US_2015_publink100010630 Option 2: If you didn't hold the underlying and the exercise of the call that you wrote resulted in a short position, you might also be able to get to a long-term gain by buying the underlying while keeping your short position open and then \"\"crossing\"\" them to close both positions after one year.

In your example, when the underlying stock reaches $110, you can theoretically make $2/share by exercising your option (buying 100 shares @ $108/share) and immediately selling those 100 shares back to the market at $110/share. This is all before commission. In more detail, you'll have these practical issues: You are going to have to pay commissions, which means you'll need a bigger spread to make this worthwhile. You and those who have already answered have you finger on this part, but I include it for completeness. (Even at expiration, if the difference between the last close price and the strike price is pretty close, some \"\"in-the-money\"\" options will be allowed to expire unexercised when the holders can't cover the closing commission costs.) The market value of the option contract itself should also go up as the price of the underlying stock goes up. Unless it's very close to expiration, the option contract should have some \"\"time value\"\" in its market price, so, if you want to close your position at this point, earlier then expiration, it will probably be better for you to sell the contract back to the market (for more money and only one commission) than to exercise and then close the stock position (for less money and two commissions). If you want to exercise and then flip the stock back as your exit strategy, you need to be aware of the settlement times.

One interpretation is that a put is not \"\"substantially identical\"\" to the disposed stock, therefore no wash is triggered by that sale. However if that put is exercised, then you automatically purchase the security, and that is identical. As to whether the IRS (or your brokerage firm) recognizes the identical security when it falls out of an option, I can't say; but technically they could enforce it because the rule is based on 30 days and a \"\"substantially identical\"\" stock or security. In this interpretation (your investor) would probably at least want to stay out of the money in choosing a strike price, to avoid exercise; however, options are normally either held or sold, rather than be exercised, until at or very close to the expiration date (because time value is left on the table otherwise). So the key driver in this interpretation would be expiration date, which should be at least 31 days out from the stock sale; and it would be prudent to sell an out of the money put as well, in order to avoid the wash sale trigger. However there is also a more unfavorable opinion - see fairmark.com/capgain/wash/wsoption.htm where they hold that a \"\"deep in the money\"\" option is an immediate trigger (regardless of exercise). This article is sage, in that they say that the Treasury (IRS) may interpret an option transaction as a wash if it's ballpark to being exercisable.

An American bond option on the dirty price of a bond (such as some convertible bonds) may be exercised immediately if ITM and a coupon is due. A put option on gold will be exercised early when deep ITM, because gold tends to hold its value whereas the currency used as the strike is often expected to lose value through inflation if the holder waits until final maturity to exercise the option (they will almost certainly exercise a contract deep ITM, minimizing its time value).[citation needed]", "title": "" }, { "docid": "288289", "text": "As other answers state, selling the options contracts to the market is a definite way out, and probably the best in most cases.

After expiration the option is worthless if it is out of the money but other than that has no hangover. Option prices normally drop as the time value of the option decays. An option has two values associated with it; time value and exercise value. Far out of the money (when the price of the underlying is far from the strike price on the losing side) options only have time value whereas deep in the money options (as yours seems to be) has some time value as well as the intrinsic value of the right to buy (sell) at a low (high) price and then sell (buy) the underlying. The time value of the option comes from the possibility that the price of the underlying will move (further) in your favour and make you more money at expiry. As expiry closes it is less likely that there will be a favourable mood so this value declines which can cause prices to move sharply after a period of little to no revaluing.

The reason they usually won't is that most options trade above their intrinsic value (the amount that they're in the money). In your example, the options aren't in the money at all. The stock is trading at 120, and the option gives the owner the right to buy at 120.* Put another way, exercising the option lets the owner buy the stock for the exact same price anyone with no options can in the market.

Clearly, at the prices you quote, it does not seem sensible to exercise your warrants at the moment, since you can still by \"\"units\"\" (1 stock + 1/3 warrant) and bare stock at below the $11.50 it would cost you to exercise your warrant. So when would exercising a warrant become \"\"a sensible thing to do\"\"? Obviously, if the price of the bare stock (which you say is currently $10.12) were to sufficiently exceed $11.50, then it would clearly be worth exercising a warrant and immediately selling the stock you receive (\"\"sufficiently exceed\"\" to account for any dealing costs in selling the newly-acquired stock). However, looking more closely, $11.50 isn't the correct \"\"cut-off\"\" price. Consider three of the units you bought at $10.26 each. For $30.78 you received three shares of stock and one warrant. For an additional $11.50 ($42.28 in total) you can have a total of four shares of stock (at the equivalent of $10.57 each). So, if the price of the bare stock rises above $10.57, then it could become sensible to exercise one warrant and sell four shares of stock (again allowing a margin for the cost of selling the stock). The trading price of the original unit (1 stock + 1/3 warrant) shouldn't (I believe) directly affect your decision to exercise warrants, although it would be a factor in deciding whether to resell the units you've already got. As you say, if they are now trading at $10.72, then having bought them at $10.26 you would make a profit if sold. Curiously, unless I'm missing something, or the figures you quote are incorrect, the current price of the \"\"unit\"\" (1 stock + 1/3 warrant; $10.72) seems overpriced compared to the price of the bare stock ($10.12). Reversing the above calculation, if bare stock is trading at $10.12, then four shares would cost $40.48. Deducting the $11.50 cost-of-exercising, this would value three \"\"combined units\"\" at $28.98, or $9.66 each, which is considerably below the market price you quote. One reason the \"\"unit\"\" (1 stock + 1/3 warrant) is trading at $10.72 instead of $9.66 could be that the market believes the price of the bare share (currently $10.12) will eventually move towards or above $11.50. If that happens, the option of exercising warrants at $11.50 becomes more and more attractive. The premium presumably reflects this potential future benefit. Finally, \"\"Surely I am misunderstand the stock IPO's intent.\"\": presumably, the main intent of Social Capital was to raise as much money as possible through this IPO to fund their future activities. The \"\"positive view\"\" is that they expect this future activity to be profitable, and therefore the price of ordinary stock to go up (at least as far as, ideally way beyond) the $11.50 exercise price, and the offering of warrants will be seen as a \"\"thank you\"\" to those investors who took the risk of taking part in the IPO. A completely cynical view would be that they don't really care what happens to the stock price, but that \"\"offering free stuff\"\" (or what looks like \"\"free stuff\"\") will simply attract more \"\"punters\"\" to the IPO.

While not everyone buys stock in lots, it's important if you do anything with (standardized) options on the stock because they are always acting on lots. In addition, even if you don't buy round lots a higher price makes it harder to buy in for a specific amount because each unit share has a greater chance to be further away from your target amount. Conversely, shares that are priced too low will also find fewer buyers, because some holders have minimum price requirements due to low price (e.g. penny) stocks tending to be more speculative and volatile. So, different funds tracking the same index might pick different price points to satisfy demand that is not being filled by other funds selling at a different price point.\"", "title": "" }, { "docid": "405474", "text": "The difference is that Yahoo is showing the unadjusted price that the security traded for on that date, while google is adjusting for price splits.

Do fundamental or technical strategies provide meaningful information? Are the signals they produce actionable? In my experience, and many quantitative traders will probably say similar things, technical analysis is unlikely to provide anything meaningful. Of course you may find phenomena when looking back on data and a particular indicator, but this is often after the fact. One cannot action-ably trade these observations. On the other hand, it does seem that fundamentals can play a crucial role in the overall (typically long run) dynamics of stock movement. Here are two examples, Technical: suppose we follow stock X and buy every time the price crosses above the 30 day moving average. There is one obvious issue with this strategy - why does this signal have significance? If the method is designed arbitrarily then the answer is that it does not have significance. Moreover, much of the research supports that stocks move close to a geometric brownian motion with jumps. This supports the implication that the system is meaningless - if the probability of up or down is always close to 50/50 then why would an average based on the price be predictive? Fundamental: Suppose we buy stocks with the best P/E ratios (defined by some cutoff). This makes sense from a logical perspective and may have some long run merit. However, there is always a chance that an internal blowup or some macro event creates a large loss. A blended approach: for sake of balance perhaps we consider fundamentals as a good long-term indication of growth (what quants might call drift). We then restrict ourselves to equities in a particular index - say the S&P500. We compare the growth of these stocks vs. their P/E ratios and possibly do some regression. A natural strategy would be to sell those which have exceeded the expected return given the P/E ratio and buy those which have underperformed. Since all equities we are considering are in the same index, they are most likely somewhat correlated (especially when traded in baskets). If we sell 10 equities that are deemed \"\"too high\"\" and buy 10 which are \"\"too low\"\" we will be taking a neutral position and betting on convergence of the spread to the market average growth. We have this constructed a hedged position using a fundamental metric (and some helpful statistics). This method can be categorized as a type of index arbitrage and is done (roughly) in a similar fashion. If you dig through some data (yahoo finance is great) over the past 5 years on just the S&P500 I'm sure you'll find plenty of signals (and perhaps profitable if you calibrate with specific numbers).

Hope my answer below can help you: Reason for price difference: 1. Vendor and data source Basically, data providers such as Google and Yahoo redistribute EOD data by aggregating data from their vendors. Although the raw data is taken from the same exchanges, different vendors tend to collect them through different trading platforms. For example, Yahoo, is getting stock data from Hemscott (which was acquired by Morningstar), which is not the most accurate source of EOD stocks. Google gets data from Deutsche Börse. To make the process more complicated, each vendor can choose to get EOD data from another EOD data provider or the exchange itself, or they can produce their own open, high, low, close and volume from the actual trade tick-data, and these data may come from any exchanges. 2. Price Adjustment For equities data, the re-distributor usually adjusts the raw data by applying certain customized procedures. This includes adjustment for corporate actions, such as dividends and splits. For futures data, rolling is required, and back-ward and for-warding rolling can be chosen. Different adjustment methods can lead to different price display. 3. Extended trading hours Along with the growth of electronic trading, many market tends to trade during extended hours, such as pre-open and post-close trading periods. Futures and FX markets even trade around the clock. This leads to another freedom in price reporting: whether to include the price movement during the extended trading hours. Conclusion To cross-verify the true price, we should always check the price from the Exchange where the asset is actually traded. Given the convenience of getting EOD data nowadays, this task should be easy to achieve. In fact, for professional traders and investors alike, they will never reply price on free providers such as Yahoo and Google, they will most likely choose Bloomberg, Reuters, etc. However, for personal use, Yahoo and Google should both be good choices, and the difference is small enough to ignore.", "title": "" }, { "docid": "189341", "text": "Another possibly more flexible option is Yahoo finance here is an example for the dow.. http://finance.yahoo.com/q/hp?s=%5EDJI&a=9&b=1&c=1928&d=3&e=10&f=2012&g=d&z=66&y=0 Some of the individual stocks you can dl directly to a spreadsheet (not sure why this isn't offer for indexs but copy and paste should work). http://finance.yahoo.com/q/hp?s=ACTC.OB+Historical+Prices", "title": "" }, { "docid": "553377", "text": "\"You could use any of various financial APIs (e.g., Yahoo finance) to get prices of some reference stock and bond index funds.

Yahoo will throttle you if you attempt to download too much data in a short time period. You can opt to use the Yahoo Query Language (YQL), which does provide another interface to their financial data apart from simply downloading the CSV files. Although the rate limit is higher for YQL, you may still run into it. An API that a paid data provider exposes will likely have higher thresholds. Although the reliability varies throughout the site, Yahoo Finance isn't considered the most reliable of sources. You can't beat free, of course, but at least for research purposes, the Center for Research in Security Prices (CRSP) at UChicago and Wharton is considered the gold standard. On the commercial side, data providers like eSignal, Bloomberg, Reuters also enjoy widespread popularity. Although both the output from YQL and Yahoo's current CSV output are fairly standard, they won't necessarily remain that way. A commercial API is basically a contract with the data provider that they won't change the format without significant prior notice, but it's reasonable to assume that if Yahoo wanted to, they could make minor changes to the format and break many commercial applications. A change in Yahoo's format would likely break many sites or applications too, but their terms of use do state that Yahoo \"\"may change, suspend, or discontinue any aspect of the Yahoo!

However, because numerous factors affect the entire market, or at least a significant subset of it, it makes sense to develop a strategy to remove all of these factors without resorting to use of an index. Using an index to remove the effect of these factors might be a good idea, but you run the risk of potentially introducing other factors that affect the index, but not Apple. I don't know what those would be, but it's a valid theoretical concern. In your question, you said you wanted to subtract them from each other, and only see an Apple curve moving around a horizontal line. The basic strategy I plan to use is similar but even simpler. Instead of graphing Apple's stock price, we can plot the difference between its stock price on business day t and business day t-1, which gives us this graph, which is essentially what you're looking for: While this is only the preliminaries, it should give you a basic idea of one procedure that's used extensively to do just what you're asking. I don't know of a website that will automatically give you such a metric, but you could download the price data and use Excel, Stata, etc. to analyze this. The reasoning behind this methodology builds heavily on time series econometrics, which for the sake of simplicity I won't go into in great detail, but I'll provide a brief explanation to satisfy the curious. In simple econometrics, most time series are approximated by a mathematical process comprised of several components: In the simplest case, the equations for a time series containing one or more of the above components are of the form that taking the first difference (the procedure I used above) will leave only the random component. However, if you want to pursue this rigorously, you would first perform a set of tests to determine if these components exist and if differencing is the best procedure to remove those that are present. Once you've reduced the series to its random component, you can use that component to examine how the process underlying the stock price has changed over the years. In my example, I highlighted Steve Jobs' death on the chart because it's one factor that may have led to the increased standard deviation/volatility of Apple's stock price. Although charts are somewhat subjective, it appears that the volatility was already increasing before his death, which could reflect other factors or the increasing expectation that he wouldn't be running the company in the near future, for whatever reason. My discussion of time series decomposition and the definitions of various components relies heavily on Walter Ender's text Applied Econometric Time Series. If you're interested, simple mathematical representations and a few relevant graphs are found on pages 1-3. Another related procedure would be to take the logarithm of the quotient of the current day's price and the previous day's price. In Apple's case, doing so yields this graph: This reduces the overall magnitude of the values and allows you to see potential outliers more clearly. This produces a similar effect to the difference taken above because the log of a quotient is the same as the difference of the logs The significant drop depicted during the year 2000 occurred between September 28th and September 29th, where the stock price dropped from 26.36 to 12.69. Apart from the general environment of the dot-com bubble bursting, I'm not sure why this occurred. Another excellent resource for time series econometrics is James Hamilton's book, Time Series Analysis. It's considered a classic in the field of econometrics, although similar to Enders' book, it's fairly advanced for most investors. I used Stata to generate the graphs above with data from Yahoo! Finance: There are a couple of nuances in this code related to how I defined the time series and the presence of weekends, but they don't affect the overall concept. For a robust analysis, I would make a few quick tweaks that would make the graphs less appealing without more work, but would allow for more accurate econometrics.", "title": "" }, { "docid": "313421", "text": "\"The Dow Jones Industrial Average (DJIA) is a Price-weighted index. That means that the index is calculated by adding up the prices of the constituent stocks and dividing by a constant, the \"\"Dow divisor\"\". (The value of the Dow divisor is adjusted from time to time to maintain continuity when there are splits or changes in the roster.) This has the curious effect of giving a member of the index influence proportional to its share price. That is, if a stock costing $100 per share goes up by 1%, that will change the index by 10 times as much as if a stock costing $10 per share goes up by the same 1%. Now look at the price of Google. It's currently trading at just a whisker under $700 per share. Most of the other stocks in the index trade somewhere between $30 and $150, so if Google were included in the index it would contribute between 5 and 20 times the weight of any other stock in the index. That means that relatively small blips in Google's price would completely dominate the index on any given day. Until June of 2014, Apple was in the same boat, with its stock trading at about $700 per share. At that time, Apple split its stock 7:1, and after that its stock price was a little under $100 per share. So, post-split Apple might be a candidate to be included in the Dow the next time they change up the components of the index. Since the Dow is fixed at 30 stocks, and since they try to keep a balance between different sectors, this probably wouldn't happen until they drop another technology company from the lineup for some reason. (Correction: Apple is in the DJIA and has been for a little over a year now. Mea culpa.) The Dow's price-weighting is unusual as stock indices go. Most indices are weighted by market capitalization. That means the influence of a single company is proportional to its total value. This causes large companies like Apple to have a lot of influence on those indices, but since market capitalization isn't as arbitrary as stock price, most people see that as ok. Also, notice that I said \"\"company\"\" and not \"\"stock\"\". When a company has multiple classes of share (as Google does), market-cap-weighted indices include all of the share classes, while the Dow has no provision for such situations, which is another, albeit less important, reason why Google isn't in the Dow. (Keep this in mind the next time someone offers you a bar bet on how many stocks are in the S&P 500. The answer is (currently) 505!) Finally, you might be wondering why the Dow uses such an odd weighting in its calculations. The answer is that the Dow averages go back to 1896, when Charles Dow used to calculate the averages by hand.

Yahoo shows EPS to be 1.34. 493.90/1.34 = P/E of 368.58 Google shows EPS to be 0.85. 493.40/0.85 = P/E of 580.47 (Prices as displayed, respectively) So, by the info that they are themselves displaying, it's Google, not Yahoo, that's displaying the wrong P/E. Note that the P/E it is showing is 5.80 -- a decimal misplacement from 580 Note that CNBC shows the Earnings as 0.85 as well, and correctly show the P/E as 580 http://data.cnbc.com/quotes/BP.L A quick use of a currency calculator reveals a possible reason why EPS is listed differently at yahoo. 0.85 pounds is 1.3318 dollars, currently. So, I think the Yahoo EPS listing is in dollars. A look at the last 4 quarters on CNBC makes that seem reasonable: http://data.cnbc.com/quotes/BP.L/tab/5 those add up to $1.40.\"", "title": "" } ]

[ { "docid": "267266", "text": "\"It's called \"\"dilution\"\". Usually it is done to attract more investors, and yes - the existing share holders will get diluted and their share of ownership shrinks.

Create 50 more shares and sell it at an arranged price to investor C. Now the percentage of each investor is 33.33%. The money that comes in will go to the company and not to A & B. From here on, A & C together can decide to slowly cut out B by, for example: After any of the above the % of shares held by B would definitely go down.\"", "title": "" }, { "docid": "154841", "text": "The short answer, probably not much. Unless you have a controlling interest in the company. If at least 50%+1 of the shareholder votes are in favor of the dilution then it can be done. There are some SEC rules that should protect against corporate looting and theft like what the Severin side is trying to make it appear as happened. However it would appear that Severin did something stupid. He signed away all of his voting right to someone who would use them to make his rights basically worthless. Had he kept his head in the game he could probably have saved himself. But he didn't. If your average startup started issuing lots of stock and devaluing existing shares significantly then I would expect it would be harder to find investors willing to watch as their investment dwindled. But if you are issuing a limited amount stock to get leverage to grow bigger then it is worth it. In the .com bubble there were quite a few companies that just issued stock to buy other companies. Eventually most of these companies got delisted because they diluted them selves to much when they were overvalued. Any company not just a startup can dilute its shares. Many if not most major companies issue stock to raise capital. This capital is then generally used to build the business further and increase the value of all shares. Most of the time this dilution is very minor (<.1%) and has little if any impact on the stock. There are rules that have to be followed as listed companies are regulated by the SEC. There are less regulations with private corporations. It looks like the dilution was combined with the buyout of the Florida company which probably contributed to the legality of the dilution. With options they are generally issued at a set price. This may be higher or lower than the reported sell price of the stock when the option is issued. The idea is over time the stock will increase in value so that those people who hold on to their options can buy the stock for the price listed on the option. I worked at an ISP start up in the 90's that made it pretty well. I left before the options were issued but I had friends still there that were issued an option at $16 a share the value of the stock at the time of the issue of the option was about 12. Well the company diluted the shares and used them to acquire more ISP's unfortunately this was about the time that DSL And cable internet took off so the dial up market tanked. The value eventually fell to .10 they did a reverse split and when they did the called in all options. The options did not have a positive cash value at any time. Had RMI ever made it big then the options could have been worth millions. There are some people from MS and Yahoo that were in early that made millions off of their options.

[ { "docid": "480119", "text": "As a start-up, the initial shares can be given at various price points. So essentially they can give someone a larger percentage based on the same amount earlier, and lesser percentage to someone else for the same amount. As its a start-up the valuations can be very tricy and what matters is that whether you believe the percentage you got for the amount is right or not. It is very important to note that when you have been given an ownership in the company, how that is designated. Is it in absolute number of shares or is it in terms of percentage based on the existing shares. For example you maybe given 100 shares, without any qualification. Or you maybe given a 5% stake in the paid-up capital, that translates to 100 shares. It is always better to hold the shares in % of the total shares. Also read the contract, any dilution should require your approval. Normally start-ups once the valuation starts to go up, start creating more shares and sell these to private equity or create more shares and give it as a bonus to promoters.

Usually the purpose is to enrich the shareholders. The owners of a company want to make money, in other words. There are a number of ways that a shareholder can make money off a stock: As such, maintaining the stock price and dividend payouts are generally the number one concern for any company in the long term. Most of the company's business is going to be directed towards making the company more valuable for a future buyout, or more valuable in terms of what it can pay its shareholders directly. Note that the company doesn't always need to be worried about the specifics of the day-to-day moves of the stock. If it keeps the finances in line - solid profits, margins, earnings growth and the like - and can credibly tell people that it's generally a valuable business, it can usually shrug off any medium-term blips as market craziness. Some companies are more explicitly long-term about things than others (e.g. Berkshire Hathaway basically tells people that it doesn't care all that much about what happens in the short term). Of course, companies are abstractions, and they're run by people. To make the people running the company worry about the stock price, you give them stock. Or stock options, or something like that. A major executive at a big company is likely to have a significant amount of stock. If the company does well, he does well; if it does poorly, he does poorly. Despite a few limitations, this is really a powerful incentive. If a company is losing a lot of money, or if its profits are falling so it's just losing a lot of its value as a business, the owners (stockholders) tend to get upset, and may vote in new management, or launch some sort of shareholder lawsuit. And, as previously noted, to raise funds, a company can also issue new shares to the market as a secondary offering as well (and they can issue fewer shares if the price is high - meaning that whatever the company is worth afterward, the existing owners own proportionally more of it).", "title": "" }, { "docid": "525590", "text": "As others have posted, the company gains capital in return for its new shares. However, the share price can still fall. The problem is that the share marked is affected by supply and demand like any other marked. If the company just issues the new shares at marked price, they will have problems finding buyers. The people who are willing to pay that price has already bought as many shares as they want. The company does this to raise capital, and depends on the shares actually selling for this to work. So, they issue shares at below marked price to attract buyers and the shares get diluted. In the end the share will usually end up somewhere between the old marked price and the issue price. The old share owners are probably not too happy about this and will not accept this plan.

Sometimes, warrant terms are such that multiple warrants are required to buy one share of stock. Consider: The conversion ratio is the number of warrants needed in order to buy (or sell) one investment unit.

There can be multiple classes of shares, but to simplify, assuming only one class of shares, a company issues some number of shares, let's say 1,000,000 shares and you can buy shares of the company. If you own 1,000 shares in this example, you would own one one-thousandth of the company. Public companies have their shares traded on the open market and the price varies as demand for the stock comes and goes relative to people willing to sell their shares. You typically buy stock in a company because you believe the company is going to prosper into the future and thus the value of its stock should rise in the open market. A bond is an indebted interest in a company. A company issues bonds to borrow money at an interest rate specified in the bond issuance and makes periodic payments of principal and interest. You buy bonds in a company to lend the company money at an interest rate specified in the bond because you believe the company will be able to repay the debt per the terms of the bond. The value of a bond as traded on the open exchange varies as the prevailing interest rates vary. If you buy a bond for $1,000 yielding 5% interest and interest rates go up to 10%, the value of your bond in the open market goes down so that the payment terms of 5% on $1,000 matches hypothetical terms of 10% on a lesser principal amount. Whatever lesser principal amount at the new rate would lead to the same payment terms determines the new market value. Alternatively, if interest rates go down, the current value of your bond increases on the open market to make it appear as if it is yielding a lower rate. Regardless of the market value, the company continues to pay interest on the original debt per its terms, so you can always hold onto a bond and get the original promised interest as long as the company does not go bankrupt. So in summary, bonds tend to be a safer investment that offers less potential return.

As Cameron says, they differ from exchange traded options in that they are issued by the financial companies whereas options are generally written by other investors. Instalment warrants on the other hand are usually bought and sold by investors with a longer term view. There are no calls and puts and you can just go long with them. They are also issued by financial companies, and how they work is best explained through an example: if I was to buy a stock directly say I would be paying $50 per share, however an instalment warrant in the underlying stock may be offered for $27 per warrant. I could buy the warrant directly from the company when it is issued or on the secondary market just like shares. I would pay the $27 per warrant upfront, and then in 2 years time when the warrant expires I have the choice to purchase the underlying stock for the strike price of say $28, roll over to a new issue of warrants, sell it back on the secondary market, or let it expire, in which case I would receive any intrinsic value left in the warrant. You would have noticed that the warrant purchase price plus the strike price adds up to more than the share price ($55 compared to $50). This is the interest component inherent in the warrant which covers the borrowing costs until expiry, when you pay the second portion (the strike price) and receive the underlying shares.

Some have relatively flat value but pay a strong dividend -- utility stocks used to be examples of that model, and bonds are in some sense an extreme version of this. Some, especially startups, pay virtually no dividends and aim for growth in the value of the stock. And you can probably find a stock that hits any point between these. This is the \"\"growth versus income\"\" spectrum you may have heard mentioned. In the past, investors took more of their return on investment as dividends -- conceptually, a share of the company's net profits for the year reflecting the share's status as partial ownership. If you wanted to do so, you could use the dividend to purchase more shares (via a dividend reinvestment plan or not), but that was up to you. These days, with growth having been strongly hyped, many companies have shifted much more to the growth model and dividends are often relatively wimpy. Essentially, this assumes that everyone wants the money reinvested and will take their profit by having that increase the value of their shares. Of course that's partly because some percentage of stockholders have been demanding growth at all costs, not always realistically. To address your specific case: No, you probably aren't buying Microsoft because you like its dividend rate; you're buying it in the hope it continues to grow in stock value. But the dividend is a bit of additional return on your investment. And with other companies the tradeoff will be different.

A Simple Scenario: If Company A wants to open a new store, for example, they need to buy the land, build the store, stock it, etc, etc and this all costs money. The company can get a loan, use accrued capital, or raise new capital by issuing new stock. Each method has benefits and drawbacks. One of the drawbacks of issuing new stock is that it dilutes the existing stock's value. Previously, total company profits were split between x shares. Now the profits are shared between x+y shares, where y is the number of new shares issued to raise the capital. This normally drives the price of the stock down, since the expected future dividends per stock have decreased. Now the company has a problem: the next time they go to raise money by issuing stock, they will have to issue MORE shares to get the same value - leading to more dilution. To break out of this cycle, the company can buy back shares periodically. When the company feels the the stock is sufficiently undervalued, it buys some back. Now the profits are shared with a smaller pool, and the stock price goes up, and the next time Company A needs to raise capital, it can issue stock. So it probably has little to do with rewarding shareholders, and more to do with lowering the \"\"cost of capital\"\" for the company in the future.\"", "title": "" }, { "docid": "135216", "text": "\"The market capitalization of a stock is the number of shares outstanding (of each stock class), times the price of last trade (of each stock class). In a liquid market (where there are lots of buyers and sellers at all price points), this represents the price that is between what people are bidding for the stock and what people are asking for the stock. If you offer any small amount more than the last price, there will be a seller, and if you ask any small amount less than the last price, there will be a buyer, at least for a small amount of stock. Thus, in a liquid market, everyone who owns the stock doesn't want to sell at least some of their stock for a bit less than the last trade price, and everyone who doesn't have the stock doesn't want to buy some of the stock for a bit more than the last trade price. With those assumptions, and a low-friction trading environment, we can say that the last trade value is a good midpoint of what people think one share is worth. If we then multiply it by the number of shares, we get an approximation of what the company is worth. In no way, shape or form does it not mean that there is 32 billion more invested in the company, or even used to purchase stock. There are situations where a 32 billion market cap swing could mean 32 billion more money was invested in the company: the company issues a pile of new shares, and takes in the resulting money. People are completely neutral about this gathering in of cash in exchange for dilluting shares. So the share price remains unchanged, the company gains 32 billion dollars, and there are now more shares outstanding. Now, in some sense, there is zero dollars currently invested in a stock; when you buy a stock, you no longer have the money, and the money goes to the person who no longer has the stock. The issue here is the use of the continuous tense of \"\"invested in\"\"; the investment was made at some point, but the money doesn't really stay in this continuous state of being. Unless you consider the investment liquid, and the option to take money out being implicit, it being a continuous action doesn't make much sense. Sometimes the money is invested in the company, when the company causes stocks to come into being and sells them. The owners of stocks has invested money in stocks in that they spent that money to buy the stocks, but the total sum of money ever spent on stocks for a given company is not really a useful value.

The efficient market hypothesis isn't accurate, but it is an acceptable rule of thumb. Now, this value -- market capitalization -- is arguably not the total value of a company: other stakeholders include bond holders, labour, management, various contract counter-parties, government and customers.

What is used is called the \"\"consideration\"\". 1.) Cash - Existing cash on the balance sheet is used. Think of it like purchasing something with your debit card. 2.) Stock - This a bit more complicated. The acquiring company issues new shares and exchanges those shares for shares of the acquiree. Because new shares are issued, this can have a dilutive effect on the stock price of the acquirer. However, it can have an accretive effect if enough synergistic value between the two companies is realized and/or expected. 3.) Debt - Basically like taking out a loan.

When it comes to which is best to use, there are quantitative analyses for that - with a specific focus on the acquirer's EPS (Earnings per share) post-deal. The factors that are considered are the forgone interest on cash, the additional interest gained from taking on debt, and the dilutive effects of issuing new stock. There is no right answer for which is best, as there are multiple different factors and circumstances involved across M&amp;A deals. Each company has different borrowing rates and synergistic value expected from their deals. One big factor is the timing and stock price of both companies during the deal.

However, if there is nothing else affecting the company's financials and investors perceive no other risks, it will probably bounce back a bit, but not back to the full value before the shares were issued. Why? Whenever a company issues more stock, the new shares dilute the value of the current shares outstanding, simply because there are now more shares of that stock trading on the market; the Earnings Per Share (EPS) Ratio will drop since the same profit and company value has to be spread across more shares. Example: If a company is valued at $100 dollars and they have 25 shares outstanding, then the EPS ratio equates to $4 per share (100/25 = 4). If the company then issues more shares (stock to employees who sell or keep them), let's say 25 more shares, then shares outstanding increase to 50, but the company's value still remains at $100 dollars. EPS now equates to $2 per share (100/50 = 2). Now, sometimes when shareholders (especially employees...and especially employees who just received them) suddenly all sell their shares, this causes a micro-panic in the market because investors believe the employees know something bad about the company that they don't. Other common shareholders then want to dump their holdings for fear of impending collapse in the company. This could cause the share price to dip a bit below the new diluted value, but again if no real, immediate risks exist, the price should go back up to the new, diluted value. Example 2: If EPS was at $4 before issuing more stock, and then dropped to $2 after issuing new stock, the micro-panic may cause the EPS to drop below $2 and then soon rebound back to $2 or more when investors realize no actual risk exists. After the dilution phase plays out, the EPS could actually even go above the pre-issuing value of $4 because investors may believe that since more stock was issued due to good profits, more profits may ensue.

Is it only when they get bought, or is there some sort of quarterly payout of profits? It's up to the shareholders of the company whether and when it pays dividends. A new startup will typically have a small number of people, perhaps 1-3, who between them control any shareholder vote (the founder(s) and an investor). If they're offering you 5%, chances are they've made sure your vote will not matter, but some companies (an equity partnership springs to mind) might be structured such that control is genuinely distributed. You would want to check what the particular situation is in this company. Assuming the founders/main investors have control, those people (or that person) will decide whether to pay dividends, so you can ask them their plans to realise money from the company. It is very rare for startups to pay any dividends. This is firstly because they're rarely profitable, but even when they are profitable the whole point of a startup is to grow, so there are plenty of things to spend cash on other than payouts to shareholders. Paying anything out to shareholders is the opposite of receiving investment. So unless you're in the very unusual position of a startup that will quickly make so much money that it doesn't need investment, and is planning to pay out to shareholders rather than spend on growth, then no, it will not pay out. One way for a shareholder to exit is to be bought out by other shareholders. For example if they want to get rid of you then they might make you an offer for your 5%. This can be any amount they think you'll take, given the situation at the time. If you don't take it, there may be things they can do in future to reduce its value to you (see below). If you do take it then your 5% would pay you once, when you leave. If the company succeeds, commonly it will be wholly or partly sold (either privately or by IPO). At this point, if it's wholly sold then the soon-to-be-ex-shareholders at the time will receive the proceeds of the sale. If it's partly sold then as with an investment round it's up for negotiation what happens. For example I believe the cash from an IPO of X% of the company could be taken into the company, leaving the shareholders with no immediate direct payout but (100-X)% of shares in their names that they're more-or-less free to sell, or retain and receive future dividends. Alternatively, if the company settles down as a small private business that's no longer in startup mode, it might start paying out without a sale. If the company fails, as most startups do, it will never pay anything. It's very important to remember that it's the shareholders at the time who receive money in proportion to their holding (or as defined by the company articles, if there are different classes of share). Just because you have 5% now doesn't mean you'll have 5% by that time, because any new investment into the company in the mean time will \"\"dilute\"\" your shareholding. It works like this: Note that I've assumed for simplicity that the new investment comes in at equal value to the old investment. This isn't necessarily the case, it can be more or less according to the terms of the new investment voted for by the shareholders, so the first line really is \"\"nominal value\"\", not necessarily the actual cash the founders put in. Therefore, you should not think of your 5% as 5% of what you imagine a company like yours might eventually exit for. At best, think of it as 5% of what a company like yours might exit for, if it receives no further investment whatsoever. Ah, but won't the founders also have their holdings diluted and lose control of the company, so they wouldn't do that? Well, not necessarily. Look carefully at whether you're being offered the same class of shares as the founders. If not consider whether they can dilute your shares without diluting their own. Look also at whether a new investor could use the founders' executive positions to give them new equity in the same way they gave you old equity, without giving you any new equity. Look at whether the founders will themselves participate in future investment rounds using sacks of cash that they own from other ventures, when you can't afford to keep up. Look at whether new investors will receive a priority class of share that's guaranteed at exit to pay out a certain multiple of the money invested before the older, inferior classes of shares receive anything (VCs like to do this, at least in the UK). Look at any other tricks they can legally pull: even if the founders aren't inclined to be tricky, they may eventually be forced to consider pulling them by a future new investor. And when I say \"\"look\"\", I mean get your lawyer to look. If your shareholding survives until exit, then it will pay out at exit. But repeated dilutions and investors with priority classes of shares could mean that your holding doesn't survive to exit even if the company does. Your 5% could turn into a nominal holding that hasn't really \"\"survived\"\", that entitles you to 0.5% of any sale value over $100 million. Then if the company sells for $50 million you get $0, while other investors are getting a good return. All of this is why you should not work for equity unless you can afford to work for free. And even then you need to lawyer up, now and during any future investment, so your lawyer can explain to you what your investment actually is, which almost certainly is different from what it looks like at a casual uninformed glance.\"", "title": "" }, { "docid": "453582", "text": "\"Investopedia explains how a stock split impacts the stock's options: Each option contract is typically in control of 100 shares of an underlying security at a predetermined strike price. To find the new coverage of the option, take the split ratio and multiply by the old coverage (normally 100 shares). To find the new strike price, take the old strike price and divide by the split ratio. Say, for example, you own a call for 100 shares of XYZ with a strike price of $75. Now, if XYZ had a stock split of 2 for 1, then the option would now be for 200 shares with a strike price of $37.50. If, on the other hand, the stock split was 3 for 2, then the option would be for 150 shares with a strike price of $50. So, yes, a 2 for 1 stock split would halve the option strike prices. Also, in case the Investopedia article isn't clear, after a split the options still control 100 shares per contract. Regarding how a dividend affects option prices, I found an article with a good explanation: As mentioned above, dividends payment could reduce the price of a stock due to reduction of the company's assets. It becomes intuitive to know that if a stock is expected to go down, its call options will drop in extrinsic value while its put options will gain in extrinsic value before it happens. Indeed, dividends deflate the extrinsic value of call options and inflate the extrinsic value of put options weeks or even months before an expected dividend payment. Extrinsic value of Call Options are deflated due to dividends not only because of an expected reduction in the price of the stock but also due to the fact that call options buyers do not get paid the dividends that the stock buyers do. This makes call options of dividend paying stocks less attractive to own than the stocks itself, thereby depressing its extrinsic value. How much the value of call options drop due to dividends is really a function of its moneyness. In the money call options with high delta would be expected to drop the most on ex-date while out of the money call options with lower delta would be least affected. If a stock is expected to drop by a certain amount, that drop would already have been priced into the extrinsic value of its put options way beforehand. This is what happens to put options of dividend paying stocks. This effect is again a function of options moneyness but this time, in the money put options raise in extrinsic value more than out of the money put options. This is because in the money put options with delta of close to -1 would gain almost dollar or dollar on the drop of a stock. As such, in the money put options would rise in extrinsic value almost as much as the dividend rate itself while out of the money put options may not experience any changes since the dividend effect may not be strong enough to bring the stock down to take those out of the money put options in the money. So, no, a dividend of $1 will not necessarily decrease an option's price by $1 on the ex-dividend date. It depends on whether it's a call or put option, and whether the option is \"\"in the money\"\" or \"\"out of the money\"\" and by how much.\"", "title": "" }, { "docid": "418150", "text": "If a stock that makes up a big part of the Dow Jones Industrial Average decided to issue a huge number of additional shares, that will make the index go up.

So, we have an ice cream shop. We started it as partners, and now you and I each own 50% of the company. It's doing so well that we decide to take it public. That means that we will be giving up some of our ownership in return for a chance to own a smaller portion of a bigger thing. With the money that we raise from selling stocks, we're going to open up two more stores. So, without getting into too much of the nitty gritty accounting that would turn this into a valuation question, let's say we are going to put 30% of the company up for sale with these stocks, leaving you and me with 35% each. We file with the SEC saying we're splitting up the company ownership with 100,000 shares, and so you and I each have 35,000 shares and we sell 30,000 to investors. Then, and this depends on the state in the US where you're registering your publicly traded corporation, those shares must be assigned a par value that a shareholder can redeem the shares at. Many corporations will use $1 or 10 cents or something nominal. And we go and find investors who will actually pay us $5 per share for our ice cream shop business. We receive $150,000 in new capital. But when we record that in our accounting, $5 in total capital per share was contributed by investors to the business and is recorded as shareholder's equity. $1 per share (totalling $30,000) goes towards actual shares outstanding, and $4 per share (totalling $120,000) goes towards capital surplus. These amounts will not change unless we issue new stocks. The share prices on the open market can fluctuate, but we rarely would adjust these. Edit: I couldn't see the table before. DumbCoder has already pointed out the equation Capital Surplus = [(Stock Par Value) + (Premium Per Share)] * (Number of Shares) Based on my example, it's easy to deduce what happened in the case you've given in the table. In 2009 your company XYZ had outstanding Common Stock issued for $4,652. That's probably (a) in thousands, and (b) at a par value of $1 per share. On those assumptions we can say that the company has 4,652,000 shares outstanding for Year End 2009. Then, if we guess that's the outstanding shares, we can also calculate the implicit average premium per share: 90,946,000 ÷ 4,652,000 == $19.52. Note that this is the average premium per share, because we don't know when the different stocks were issued at, and it may be that the premiums that investors paid were different. Frankly, we don't care. So clearly since \"\"Common Stock\"\" in 2010 is up to $9,303 it means that the company released more stock. Someone else can chime in on whether that means it was specifically a stock split or some other mechanism... it doesn't matter. For understanding this you just need to know that the company put more stock into the marketplace... 9,303 - 4,652 == 4,651(,000) more shares to be exact. With the mechanics of rounding to the thousands, I would guess this was a stock split. Now. What you can also see is that the Capital Surplus also increased. 232,801 - 90,946 == 141,855. The 4,651,000 shares were issued into the market at an average premium of 141,855 ÷ 4,651 == $30.50. So investors probably paid (or were given by the company) an average of $31.50 at this split. Then, in 2011 the company had another small adjustment to its shares outstanding. (The Common Stock went up). And there was a corresponding increase in its Capital Surplus.

In other words, if employee stock option rights are surrendered to an employer for cash or an in-kind payment, then (subject to new subsections 110(1.1) and (1.2)) the employer may deduct the payment but the employee cannot claim the stock option deduction. Conversely, where an employer issues securities pursuant to an employee’s exercise of stock options, the employer can not deduct an amount in respect of the issuance, but the employee may be eligible to claim a deduction under paragraph 110(1)(d). Did you receive real shares based on your participation in the ESPP, or did you get a cash payment for the net value of shares you would have been issued under the plan? From what I can tell, if you opted for a cash payment (or if your plan only allows for such), then the part I emphasized comes into play. Essentially, if conditions were such that your employer could claim a deduction on their corporate income tax return for the compensation paid to you as part of the plan, then you are not also able to claim a similar deduction on your personal income tax return. The money received in that manner is effectively taxed in your hands the same as any bonus employment income would be; i.e. it isn't afforded tax treatment equivalent to capital gains income.

However, what someone's willing to pay for it is typically based on what the person can get from it. There are a couple of ways to value a stock. The first way is on expected earnings per share, most of would normally (but not always) be paid in dividends. This is a metric that can be calculated based on the most recently reported earnings, and can be estimated based on news about the company or the industry its in (or those of suppliers, likely buyers, etc) to predict future earnings. Let's say the stock price is exactly $100 right now, and you buy one share. In one quarter, the company is expected to pay out $2 per share in dividends. That is a 2% ROI realized in 3 months. If you took that $2 and blew it on... coffee, maybe, or you stuffed it in your mattress, you'd realize a total gain of $8 in one year, or in ROI terms an annual rate of 8%. However, if you reinvested the money, you'd be making money on that money, and would have a little more. You can calculate the exact percentage using the \"\"future value\"\" formula. Conversely, if you wanted to know what you should pay, given this level of earnings per share, to realize a given rate of return, you can use the \"\"present value\"\" formula. If you wanted a 9% return on your money, you'd pay less for the stock than its current value, all other things being equal. Vice-versa if you were happy with a lesser rate of return. The current rate of return based on stock price and current earnings is what the market as a whole is willing to tolerate. This is how bonds are valued, based on a desired rate of return by the market, and it also works for stocks, with the caveat that the dividends, and what you'll get back at the \"\"end\"\", are no longer constant as they are with a bond. Now, in your case, the company doesn't pay dividends. Ever. It simply retains all the earnings it's ever made, reinvesting them into doing new things or more things. By the above method, the rate of return from dividends alone is zero, and so the future value of your investment is whatever you paid for it. People don't like it when the best case for their money is that it just sits there. However, there's another way to think of the stock's value, which is it's more core definition; a share of the company itself. If the company is profitable, and keeps all this profit, then a share of the company equals, in part, a share of that retained earnings. This is very simplistic, but if the company's assets are worth 1 billion dollars, and it has one hundred million shares of stock, each share of stock is worth $10, because that's the value of that fraction of the company as divided up among all outstanding shares. If the company then reports earnings of $100 million, the value of the company is now 1.1 billion, and its stock should go up to $11 per share, because that's the new value of one ten-millionth of the company's value. Your ROI on this stock is $1, in whatever time period the reporting happens (typically quarterly, giving this stock a roughly 4% APY). This is a totally valid way to value stocks and to shop for them; it's very similar to how commodities, for instance gold, are bought and sold. Gold never pays you dividends. Doesn't give you voting rights either. Its value at any given time is solely what someone else will pay to have it. That's just fine with a lot of people right now; gold's currently trading at around $1,700 an ounce, and it's been the biggest moneymaker in our economy since the bottom fell out of the housing market (if you'd bought gold in 2008, you would have more than doubled your money in 4 years; I challenge you to find anything else that's done nearly as well over the same time). In reality, a combination of both of these valuation methods are used to value stocks. If a stock pays dividends, then each person gets money now, but because there's less retained earnings and thus less change in the total asset value of the company, the actual share price doesn't move (much). If a stock doesn't pay dividends, then people only get money when they cash out the actual stock, but if the company is profitable (Apple, BH, etc) then one share should grow in value as the value of that small fraction of the company continues to grow. Both of these are sources of ROI, and both are seen in a company that will both retain some earnings and pay out dividends on the rest.\"", "title": "" }, { "docid": "313372", "text": "\"There are a few other items that you should be aware of when getting options: The strike price is usually determined by an independent valuation of the common shares (called a 409a valuation).

There are two kinds in the US: Non-quals (NQO) and Incentive Stock Options (ISOs). The big difference is that when you exercise Non-quals, you have to pay the tax on the difference between the \"\"fair\"\" market value on the shares and what you paid for them (the strike price). This is important because if the company is private, you likely can not sell any shares until it is public. With ISOs, you don't pay any tax (except AMT tax) on the gain until you actually sell the shares. You should know what kind your getting. Some plans allow for early exercise, essentially allowing you to buy the shares early (and given back if you leave before they vest) which helps you establish capital gains treatment earlier as well as avoid AMT if you have ISOs.

Company B has good revenue but high costs of goods and total liabilities well in excess of total assets, it's trading for $0.10 per share. There is no benefit to getting 10,000 shares or 10 shares for your $1,000. Your goal is to invest in companies that have valuable products and services run by competent management teams. Sure, the number of shares you own will dictate what percentage of the company you own, and in a number of cases, your voting power. But even a penny stock will have a market capitalization of several million dollars so voting power isn't really a concern for your $1,000 investment. There is a lot more in the three basic financial statements (Income Statement, Balance Sheet, Statement of Cash Flows) than revenue. Seasoned accountants can have a hard time parsing out where money is coming from and where it's going. In general there are obvious red flags, like a fast declining cash balance against a fast growing liabilities balance or expenses exceeding revenue. While some of these things are common among new and high growth companies, it's not the place for a new investor with a small bankroll. A micro-cap company (penny stocks are in this group) will receive rounds of financing via issuing preferred convertible shares which may include options on more shares. For a company worth $20mm a $5mm financing round can materially change the finances of a company, and will likely dilute your holdings in common stock. Small growth companies need new financing frequently to fund their growth strategies. Revenue went up, great... why? Did you open another store? Did you open another sales office? Did the revenue increase this quarter based on substantially the same operation that existed last quarter or have you increased the capacity of your operation? If you increased the capacity of your operation what was the cost of the increase and did revenue increase as expected? Can you expect revenue to continue to grow at this rate or was it a one time windfall from an unusual order? Sure, there are spectacular gains to be had in penny stocks.

To address the question of what the alternatives are, on popular stocks like SIRI, a deep In-The-Money put is a fairly accurate emulation of an actual short interest. If you look at the options on SIRI you will see that a $3 (or higher) put has a delta of -$1, which is the same delta as an actual short share.

Usually, these \"\"shares\"\" are all equal; if you own one share you own a percentage of the company equal to that of anyone else who owns one share. The sum total of all shares, theoretically, equals the entire value of the company, and so with N shares in existence, one share is equivalent to 1/Nth the company, and entitles you to 1/Nth of the profits of the company, and more importantly to some, gives you a vote in company matters which carries a weight of 1/Nth of the entire shareholder body. Now, not all of these shares are public. Most companies have the majority (51%+) of shares owned by a small number of \"\"controlling interests\"\". These entities, usually founding owners or their families, may be prohibited by agreement from selling their shares on the open market (other controlling interests have right of first refusal). For \"\"private\"\" companies, ALL the shares are divided this way. For \"\"public\"\" companies, the remainder is available on the open market, and those shares can be bought and sold without involvement by the company. Buyers can't buy more shares than are available on the entire market. Now, when a company wants to make more money, a high share price at the time of the issue is always good, for two reasons. First, the company only makes money on the initial sale of a share of stock; once it's in a third party's hands, any profit from further sale of the stock goes to the seller, not the company. So, it does little good to the company for its share price to soar a month after its issue; the company's already made its money from selling the stock. If the company knew that its shares would be in higher demand in a month, it should have waited, because it could have raised the same amount of money by selling fewer shares. Second, the price of a stock is based on its demand in the market, and a key component of that is scarcity; the fewer shares of a company that are available, the more they'll cost. When a company issues more stock, there's more shares available, so people can get all they want and the demand drops, taking the share price with it. When there's more shares, each share (being a smaller percentage of the company) earns less in dividends as well, which figures into several key metrics for determining whether to buy or sell stock, like earnings per share and price/earnings ratio. Now, you also asked about \"\"dilution\"\". That's pretty straightforward. By adding more shares of stock to the overall pool, you increase that denominator; each share becomes a smaller percentage of the company. The \"\"privately-held\"\" stocks are reduced in the same way. The problem with simply adding stocks to the open market, getting their initial purchase price, is that a larger overall percentage of the company is now on the open market, meaning the \"\"controlling interests\"\" have less control of their company. If at any time the majority of shares are not owned by the controlling interests, then even if they all agree to vote a certain way (for instance, whether or not to merge assets with another company) another entity could buy all the public shares (or convince all existing public shareholders of their point of view) and overrule them. There are various ways to avoid this. The most common is to issue multiple types of stock. Typically, \"\"common\"\" stock carries equal voting rights and equal shares of profits. \"\"Preferred stock\"\" typically trades a higher share of earnings for no voting rights. A company may therefore keep all the \"\"common\"\" stock in private hands and offer only preferred stock on the market. There are other ways to \"\"class\"\" stocks, most of which have a similar tradeoff between earnings percentage and voting percentage (typically by balancing these two you normalize the price of stocks; if one stock had better dividends and more voting weight than another, the other stock would be near-worthless), but companies may create and issue \"\"superstock\"\" to controlling interests to guarantee both profits and control. You'll never see a \"\"superstock\"\" on the open market; where they exist, they are very closely held. But, if a company issues \"\"superstock\"\", the market will see that and the price of their publicly-available \"\"common stock\"\" will depreciate sharply. Another common way to increase market cap without diluting shares is simply to create more shares than you issue publicly; the remainder goes to the current controlling interests. When Facebook solicited outside investment (before it went public), that's basically what happened; the original founders were issued additional shares to maintain controlling interests (though not as significant), balancing the issue of new shares to the investors. The \"\"ideal\"\" form of this is a \"\"stock split\"\"; the company simply multiplies the number of shares it has outstanding by X, and issues X-1 additional shares to each current holder of one share. This effectively divides the price of one share by X, lowering the barrier to purchase a share and thus hopefully driving up demand for the shares overall by making it easier for the average Joe Investor to get their foot in the door. However, issuing shares to controlling interests increases the total number of shares available, decreasing the market value of public shares that much more and reducing the amount of money the company can make from the stock offering.\"", "title": "" } ]

METHODS: The design was a controlled human crossover study (n = 6). Subjects consumed a self-restricted glucosinolate-free diet 48 h before the study-day where a basic diet supplemented with 80 or 350 g of mixed cruciferous vegetables was consumed.

RESULTS: There was no significant difference between vegans and omnivores in LSBMD (0.74 +/- 0.14 vs. 0.77 +/- 0.14 g/cm(2); mean +/- SD; P = 0.18), FNBMD (0.62 +/- 0.11 vs. 0.63 +/- 0.11 g/cm(2); P = 0.35), WBBMD (0.88 +/- 0.11 vs. 0.90 +/- 0.12 g/cm(2); P = 0.31), lean mass (32 +/- 5 vs. 33 +/- 4 kg; P = 0.47), and fat mass (19 +/- 5 vs. 19 +/- 5 kg; P = 0.77) either before or after adjusting for age. The prevalence of osteoporosis (T scores < or = -2.5) at the femoral neck in vegans and omnivores was 17.1% and 14.3% (P = 0.57), respectively. The median intake of dietary calcium was lower in vegans compared to omnivores (330 +/- 205 vs. 682 +/- 417 mg/day, P < 0.001); however, there was no significant correlation between dietary calcium and BMD. Further analysis suggested that whole body BMD, but not lumbar spine or femoral neck BMD, was positively correlated with the ratio of animal protein to vegetable protein. CONCLUSION: These results suggest that, although vegans have much lower intakes of dietary calcium and protein than omnivores, veganism does not have adverse effect on bone mineral density and does not alter body composition.", "title": "Veganism, bone mineral density, and body composition: a study in Buddhist nuns." } ]

OBJECTIVE: We aimed to explore biomarkers of dairy fat intake in plasma and erythrocytes and to assess the hypothesis that higher concentrations of these biomarkers are associated with a greater risk of IHD in US women. DESIGN: Among 32,826 participants in the Nurses' Health Study who provided blood samples in 1989-1990, 166 incident cases of IHD were ascertained between baseline and 1996. These cases were matched with 327 controls for age, smoking, fasting status, and date of blood drawing. RESULTS: Among controls, correlation coefficients between average dairy fat intake in 1986-1990 and 15:0 and trans 16:1n-7 content were 0.36 and 0.30 for plasma and 0.30 and 0.32 for erythrocytes, respectively. In multivariate analyses, with control for age, smoking, and other risk factors of IHD, women with higher plasma concentrations of 15:0 had a significantly higher risk of IHD. The multivariate-adjusted relative risks (95% CI) from the lowest to highest tertile of 15:0 concentrations in plasma were 1.0 (reference), 2.18 (1.20, 3.98), and 2.36 (1.16, 4.78) (P for trend = 0.03).

This study examined the associations of objectively assessed sedentary time and breaks (interruptions) in sedentary time with continuous cardio-metabolic and inflammatory risk biomarkers, and whether these associations varied by sex, age, and/or race/ethnicity. Methods and results Cross-sectional analyses with 4757 participants (≥20 years) from the 2003/04 and 2005/06 US National Health and Nutrition Examination Survey (NHANES). An Actigraph accelerometer was used to derive sedentary time [<100 counts per minute (cpm)] and breaks in sedentary time. Independent of potential confounders, including moderate-to-vigorous exercise, detrimental linear associations (P for trends <0.05) of sedentary time with waist circumference, HDL-cholesterol, C-reactive protein, triglycerides, insulin, HOMA-%B, and HOMA-%S were observed. Independent of potential confounders and sedentary time, breaks were beneficially associated with waist circumference and C-reactive protein (P for trends <0.05). There was limited evidence of meaningful differences in associations with biomarkers by age, sex, or race/ethnicity. Notable exceptions were sex-differences in the associations of sedentary time and breaks with HDL-cholesterol, and race/ethnicity differences in the association of sedentary time with waist circumference with associations detrimental in non-Hispanic whites, null in Mexican Americans, and beneficial in non-Hispanic blacks.

Although there might be various different triggering events in the early stages of the disease, they seem to converge on a few characteristic final pathways in the late stages, characterized by inflammation and neurodegeneration. In this review, we put forward the hypothesis that advanced glycation end products (AGEs) and their precursors, including methylglyoxal, are both biomarkers and causative agents (\"gerontotoxins\") characteristic for this disorder. Accumulation of AGEs is a normal feature of aging, but is accelerated in AD, where AGEs can be detected in amyloid plaques and neurofibrillary tangles. AGE modification may explain many of the neuropathological and biochemical features of AD such as extensive protein cross-linking, inflammation, oxidative stress and neuronal cell death. We suggest that methylglyoxal is one of the major carbonyl species responsible for the formation of AGEs. We propose that one promising pharmacological approach to prevent the formation of AGEs would be to lower the methylglyoxal concentration. This can be achieved, for example, by decreasing the concentration of methylglyoxal precursors such as d-glyceraldehyde-3-phosphate by allowing a higher flux through the pentose phosphate pathway or by increasing methylglyoxal detoxification through the glyoxalase system. Alternatively, methylglyoxal could be scavenged by various types of carbonyl scavengers. Copyright © 2010 Elsevier Inc.

Confirmation of this finding with use of a biomarker is warranted. OBJECTIVE: We prospectively investigated the relation of plasma cholesterol ester (CE) and phospholipid (PL) fatty acid composition with the incidence of diabetes mellitus. DESIGN: In 2909 adults aged 45-64 y, plasma fatty acid composition was quantified by using gas-liquid chromatography and was expressed as a percentage of total fatty acids. Incident diabetes (n = 252) was identified during 9 y of follow-up. RESULTS: After adjustment for age, sex, baseline body mass index, waist-to-hip ratio, alcohol intake, cigarette smoking, physical activity, education, and parental history of diabetes, diabetes incidence was significantly and positively associated with the proportions of total saturated fatty acids in plasma CE and PL. The rate ratios of incident diabetes across quintiles of saturated fatty acids were 1.00, 1.36, 1.16, 1.60, and 2.08 (P = 0.0013) in CE and 1.00, 1.75, 1.87, 2.40, and 3.37 (P < 0.0001) in PL.

DESIGN: Middle-aged unmedicated subjects (n = 72) with cardiovascular risk factors consumed moderate amounts of berry or control products for 8 wk in a single-blind, randomized, placebo-controlled intervention trial.

RESEARCH DESIGN AND METHODS We used neutron activation analysis to measure toenail mercury, an objective biomarker of methylmercury exposure, in 9,267 adults free of diabetes at baseline in two separate U.S. prospective cohorts. Incident diabetes was identified from biennial questionnaires and confirmed by validated supplementary questionnaire using symptoms, diagnostic tests, and medical therapy. Associations of mercury exposure with incident diabetes were assessed using Cox proportional hazards. RESULTS During mean ± SD follow-up of 19.7 ± 7.0 years, 1,010 new cases of diabetes were diagnosed. The 95th percentile of toenail mercury was 1.32 μg/g in men and 0.76 μg/g in women, corresponding to exposures ∼3.5-fold and 2-fold higher than the U.S. Environmental Protection Agency reference dose. In multivariable analyses, toenail mercury concentrations were not associated with higher incidence of diabetes in women, men, or both cohorts combined.

Isothiocyanates, such as sulforaphane from broccoli, are very potent inactivators of MIF tautomerase activity. A simple rapid method for determining this activity in tissues and body fluids may therefore be valuable for assessing severity of inflammation and efficacy of intervention. Methods Existing spectrophotometric assays of MIF, based on conversion of methyl L-dopachrome to methyl 5,6-dihydroxyindole-2-carboxylate and associated loss of absorption at 475 nm, lack sensitivity. Assay sensitivity and efficiency were markedly improved by reducing the nonenzymatic rate, by lowering pH to 6.2, replacing phosphate (which catalyzes the reaction) with Bis-Tris buffer, and converting to a microtiter plate format. Results A structure-potency study of MIF tautomerase inactivation by isothiocyanates showed that sulforaphane, benzyl, n-hexyl, and phenethyl isothiocyanates were especially potent. MIF tautomerase could be readily quantified in human urine concentrated by ultrafiltration. This activity comprised: (i) a heat-labile, sulforaphane-inactivated macromolecular fraction (presumably MIF) that was concentrated during ultrafiltration; (ii) a flow-through fraction, with constant activity during filtration, that was heat-stable, and insensitive to sulforaphane. Administration of the sulforaphane precursor glucoraphanin to human volunteers almost completely abolished urinary tautomerase activity, which was recovered over many hours.

Since 1968, US citizens are protected from credit card fraud, limiting the out-of-pocket loss to $50 if your card is lost, stolen, or otherwise used without your permission. That means the bank can't make you pay more than $50 if you report unauthorized activity--and, nicely, many credit cards these days go ahead and waive the $50 too, so you might not have to pay anything (other than the necessary time and phone calls). Of course, many banks offer a $50 cap or no fees at all for fraudulent charges--my bank once happily resolved some bad charges for me at no loss to me--but banks are under no obligation to shield debit card customers from fraud. If you read the fine print on your debit card account agreement you may find some vague promises to resolve your dispute, but probably nothing saying you cannot be held liable (the bank is not going to lose money on you if they are unable to reverse the charges!). Now a personal story: I once had my credit card used to buy $3,000 in stereo equipment, at a store I had never heard of in a state I have never visited. The bank notified me of the surprising charges, and I was immediately able to begin the fraud report--but it took months of calls before the case was accepted and the charges reversed. So, yes, there was no money out of my pocket, but I was completely unable to use the credit card, and every month they kept on piling on more finance fees and late-payment charges and such, and I would have to call them again and explain again that the charges were disputed... Finally, after about 8 months in total, they accepted the fraud report and reversed all the charges. Lastly, I want to mention one more important tool for preventing or limiting loss from online purchases: \"\"disposable\"\", one-time-use credit card numbers. At least a few credit card providers (Citibank, Bank of America, Discover) offer you the option, on their websites, to generate a credit card number that charges your account, but under the limits you specify, including a maximum amount and expiration date. With one of these disposable numbers, you can pay for a single purchase and be confident that, even if the number were stolen in-transit or the merchant a fraud, they don't have your actual credit card number, and they can never charge you again. I have not yet seen this option for debit card customers, but there must be some banks that offer it, since it saves them a lot of time and trouble in pursuing defrauders. So, in short: If you pay with a credit card number you will not ever have to pay more than $50 for fraudulent charges. Even better, you may be able to use a disposable/one-time-use credit card number to further limit the chances that your credit is misused.

There are separate issues here. There is no law limiting bank accounts to U.S. citizens, but most banks will not open an account for a non-citizen outside their declared service area. There are substantial legal liabilities to the bank in allowing it, whether a citizen or non-citizen. The difficulty will be compliance with the Patriot Act. This is an extension of the older \"\"Know Your Customer\"\" doctrine. It is improbable that the bank could comply with the Act without the potential customer being physically present. You would have to check with your bank in advance as to their policies. Banks are not required to accept a customer outside their policies. As to waiving the foreign transaction fee, that is very improbable. Although a handful of institutions do this in specific cases it is uncommon because the bank isn't actually charging the fee, they are passing it along. With a credit card they collect interest and waiving the fee can be thought of as a reduction in interest income, that isn't possible on a debit card.

This is a bigger issue at the federal level because 4,000 federal laws do not require criminal intent. Some do not require you to even know the action happened. Unlike state law which generally requires you intended to commit a crime and had to be aware of it, federal law often does not.

If the account is indeed a UGMA account, the bank is supposed to not let the custodian operate the account once the child becomes an adult, but this does not always happen. There was a question earlier on money.SE (which I cannot find at this time) in which the 25-year-old person asking the question claimed that his father was still buying and selling shares in his UGMA brokerage account and the IRS was asking why the profits and losses from these transactions were not being reported on the 25-year-old's tax return. Money in an UGMA account is not supposed to be used for payment of household expenses, food, etc. which is the parent's responsibility during the minority, but this can well be abused. As to whether money was taken out and then restored (or possibly not restored, as you seem to suspect), it is possible to sue the custodian for improper handling of the UGMA account and recover the funds, but whether one wants to sue a parent over what might be a relatively small sum is another matter. Consider whether most of what is recovered might go to pay legal fees or other costs of the recovery process, and will likely ruin a family relationship.

That means it is likely possible for a merchant to reject those gift cards while still accepting other cards from that network. This is likely for certain transactions. For example, a hotel or car rental agency requires a credit card for incidentals, and it's likely that the system itself will outright reject a gift card even if it has enough on it for the initial hold.

It can go generally one of three ways: A) The loan company reports the status to a credit reporting agency on behalf of both the initiating borrower and the cosigner. In this scenario, both individuals get a new account on their credit report. Initially this will generally drop related credit scores somewhat (it's a \"\"hard pull\"\", new account with zero history, and increased debt), but over time this can have a positive effect on both people's credit rating. This is the typical scenario one might logically expect to be the norm, and it effects both parties credit just as if they were a sole signor for the loan. And as always, if the loan is not paid properly it will negatively effect both people's credit, and the owner of the loan can choose to come after either or both parties in whatever order they want. B) The loan company just runs the loan with one person, and only reports to a credit agency on one of you (probably the co-signor), leaving the other as just a backup. If you aren't paying close attention they may even arrange it where the initial party wanting to take the loan isn't even on most of the paperwork. This let the person trying to run the loan get something accepted that might not have been otherwise, or save some time, or was just an error. In this case it will have no effect on Person A's credit. We've had a number of question like this, and this isn't really a rare occurrence. Never assume people selling you things are necessarily accurate or honest - always verify. C) The loan company just doesn't report the loan at all to a credit agency, or does so incorrectly. They are under no obligation to report to credit agencies, it's strictly up to them. If you don't pay then they can report it as something \"\"in collections\"\". This isn't the typical way of doing business for most places, but some businesses still operate this way, including some places that advertise how doing business with them (paying them grossly inflated interest rates) will \"\"help build your credit\"\". Most advertising fraud goes unpunished. Note: Under all of the above scenarios, the loan can only effect the credit rating attached to the bureau it is reported to. If the loan is reported to Equifax, it will not help you with a TransUnion or Experian rating at all. Some loans report to multiple credit bureaus, but many don't bother, and credit bureaus don't automatically copy each other. It's important to remember that there isn't so much a thing as a singular \"\"consumer credit rating\"\", as there are \"\"consumer credit ratings\"\" - 3 of them, for most purposes, and they can vary widely depending on your reported histories. Also, if it is only a short-term loan of 3-6 months then it is unlikely to have a powerful impact on anyone's credit rating. Credit scores are formulas calibrated to care about long-term behavior, where 3 years of perfect credit history is still considered a short period of time and you will be deemed to have a significant risk of default without more data. So don't expect to qualify for a prime-rate mortgage because of a car loan that was paid off in a few months; it might be enough to give you a score if you don't have one, but don't expect much more.

Pay your bills, keep your average account age high, overpay your credit card minimums, and keep your overall debt low. And do soft pulls on your credit report to see what's happening. First, the simplest route: pay all your bills early or on time. Automatic deduction may be useful in this regard, especially for bills with predictable amounts. A corollary to this tip is to never leave an unpaid bill. What often happens to young people is in the course of moving around they leave the final bill unpaid and it gets reported to collections. Make sure you follow up online with all bills, even after canceling the service. Second, average account age and oldest account age matter. Open an account like a credit card and never close it, so you'll have an older account (hopefully a zero-fee card). Try to keep other accounts open rather than closing them (no need to cancel a zero-fee credit card) so your average account age stays higher. A card that works on internal systems (like a gift card) is not going to show up on a credit report; a card that works like any VISA/MC is likely going to show up. The rule of thumb is if they need your SSN to run a credit check for the application, then the card will appear on a credit report. You can pull your credit report to find out if the card is listed (you may have to allow time for lag before the card appears, but I'm not sure how long that might be). Third, a tip for extra credit score is to pay more than the minimum required on credit card bills. You can achieve this by either using your credit card at least once a month or by leaving a small hanging balance each month so there's always something to overpay next month. Credit card reporting will be either: unpaid, underpaid, minimum paid, or overpaid. Minimum payment helps your score and overpayment helps more. If you can use your credit card every month, that will give you something to overpay every month. Otherwise, you can leave a small debt left on the card but still pay over the monthly minimum. However, your total debt load, especially debt carried on your cards, counts against your score; aim for less than 10% of your limit. Finally, of course, is to pull your credit report periodically. You need to know what others are seeing. Since debt load utilization matters, make sure the reported card maximum is correct on your credit report. Talk to your bank or account issuer if the limit is wrong. If a collection appears, then you need to handle it. Often you can negotiate with the collector, but be careful to negotiate how they will report the resolution. You want them to agree to remove any negative information (either in exchange for payment or because of a mistake). Failing that, you want them to mark it paid in full or satisfied in full; letting them notate your score that you only partially paid is what you want to avoid, since it most signals someone with cash flow problems and credit issues. They control their reporting to credit bureaus, so if the person on the phone demurs, ask to speak to their supervisor or someone with negotiating authority. Try to get any agreements in writing.

Even if you're buying a condo, you'll want to be sure you can fix anything that needs fixing within that first year or two. Beyond that, you have to decide based on your risk tolerance and your other details, like your income. Taking a smaller mortgage means a guaranteed 3% to 4% return, right now. That's not quite what you'll probably get on the market over the long term, but how did your investments do last year? My 401(k) was down slightly... In order to do better than that 3-4%, you're going to have to invest in stocks (or ETFs or similar), meaning you could have 10+% swings potentially year over year, which if that's your only (extra) 50k might be more than you can tolerate. If you're very risk tolerant and mostly looking to make money over the long term, then it may be worth it to you.

[ { "docid": "322825", "text": "\"Here in the UK, the rule of thumb is to keep a lot of equity in your home if you can. I assume here that you have a lot of savings you're considering using. If you only have say 10% of the house price you wouldn't actually have a lot of choice in the matter, the mortgage lender will penalise you heavily for low deposits. The practical minimum is 5%, but for most people a 95% mortgage is just silly (albeit not as silly as the 100% or greater mortgages you could get pre-2008), and you should take serious individual advice before considering it. According to Which, the average in the UK for first-time buyers is 20% (not the best source for that data I confess, but a convenient one). Above 20% is not at all unusual. You'll do an affordability calculation to figure out how much you can borrow, which isn't at all the same as how much you should borrow, but does get you started. Basically you, decide how much a month you can spend on mortgage payments. The calculation will let you put every penny into this if you choose to, but in practice you'll want some discretionary income so don't do that. decide the term of the mortgage. For a young first-time buyer in the UK I think you'd typically take a 25-year term and consider early repayment options rather than committing to a shorter term, but you don't have to. Mortgage lenders will offer shorter terms as long as you can afford the payments. decide how much you're putting into a deposit make subtractions for cost of moving (stamp duty if applicable, fees, removals aka \"\"people to lug your stuff\"\"). receive back a number which is the house price you can pay under these constraints (and of course a breakdown of what the mortgage principle would be, and the interest rate you'll pay). This step requires access to lender information, since their rates depend on personal details, deposit percentage, phase of the moon, etc. Our mortgage advisor did multiple runs of the calculation for us for different scenarios, since we hadn't made up our minds entirely. Since you have not yet decided how much deposit to make, you can use multiple calculations to see the effect of different deposits you might make, up to a limit of your total savings. Putting up more deposit both increases the amount you can borrow for a given monthly payment (since mortgage rates are lower when the loan is a lower proportion of house value), and of course increases the house price you can afford. So unless you're getting a very high return on your savings, £1 of deposit gets you somewhat more than £1 of house, and the calculation will tell you how much more. Once you've chosen the house you want, the matter is even simpler: do you prefer to put your savings in the house and borrow less and make lower payments, or prefer to put your savings elsewhere and borrow more and make higher payments but perhaps have some additional income from the savings. Assuming you maintain a contingency fund, a lower mortgage is generally considered a good investment in the UK, but you need to check what's right for you and compare it to other investments you could make. The issue is complicated by the fact that residential property prices are rising quite quickly in most areas of the UK, and have been for a long time, meaning that highly-leveraged property investment appears to be a really good idea. This leads to the imprudent, but tempting, conclusion that you should buy the biggest house you can possibly afford and watch its value rises. I do not endorse this advice personally, but it's certainly true that in a sharply rising house market it's easier to get away with buying a bigger house than you need, than it is to get away with it in a flat or falling market. As Stephen says, an offset mortgage is a no-brainer good idea if the rate is the same. Unfortunately in the UK, the rate isn't the same (or anyway, it wasn't a couple of years ago). Offset mortgages are especially good for those who make a lot of savings from income and for any reason don't want to commit all of those savings to a traditional mortgage payment. Good reasons for not wanting to do that include uncertainty about your future income and a desire to have the flexibility to actually spend some of it if you fancy :-)\"", "title": "" }, { "docid": "92038", "text": "\"When you compare the costs of paying your current mortgage with the rental income from the flat, you're not really comparing like with like. Firstly, the mortgage payments are covering both interest and capital repayments, so some of the 8k is money that is adding to your net worth. Secondly, the value of the flat (130k) is much more than the outstanding mortgage (80k) so if you did sell the flat and pay off the mortgage, you'd have 50k left in cash that could be invested to provide an income. The right way to compare the two options is to look at the different costs in each scenario. Let's assume the bigger house will cost 425k as it makes the figures work out nicely. If you buy the bigger house with a bigger mortgage, you will need to borrow 50k more so will end up with a mortgage of 130k, and you will still have the 8k/year from the flat. Depending on your other income, you might have to pay tax on the 8k/year - e.g. at 40% if you're a higher-rate taxpayer, leaving you with 4.8k/year. If you sell the flat, you'll have no mortgage repayments to make and no income from the flat. You'll be able to exactly buy the new house outright with the 50k left over after you repay the mortgage, on top of your old house. You'd also have to pay some costs to sell the flat that you wouldn't have to with the bigger mortgage, but you'd save on the costs of getting a new mortgage. They probably aren't the same, but let's simplify and assume they are. If anything the costs of selling the flat are likely to be higher than the mortgage costs. Viewed like that, you should look at the actual costs to you of having a 130k mortgage, and how much of that would be interest. Given that you'll be remortgaging, at current mortgage rates, I'd expect interest would only be 2-3%, i.e around 2.5k - 4k, so significantly less than the income from the flat even after tax. The total payment would be more because of capital repayment, but you could easily afford the cashflow difference. You can vary the term of the mortgage to control how much the capital repayment is, and you should easily be able to get a 130k mortgage on a 425k house with a very good deal. So if your figure of 8k rent is accurate (considering void periods, costs of upkeep etc), then I think it easily makes sense to get the bigger house with the bigger mortgage. Given the tax impact (which was pointed out in a comment), a third strategy may be even better: keep the flat, but take out a mortgage on it in exchange for a reduced mortgage on your main house. The reason for doing it that way is that you get some tax relief on the mortgage costs on an investment property as long as the income from that property is higher than the costs, whereas you don't on your primary residence. The tax relief used to just be at the same tax rate you were paying on the rental income, i.e. you could subtract the mortgage costs from the rental income when calculating tax. It's gradually being reduced so it's just basic rate tax relief (20%) even if you pay higher-rate tax, but it still could save you some money. You'd need to look at the different mortgage costs carefully, as \"\"buy-to-let\"\" mortgages often have higher interest rates.\"", "title": "" }, { "docid": "583918", "text": "\"Ultimately you are as stuck as all other investors with low returns which get taxed.

I closed a couple of weeks ago. Note that I live in Texas, and that I'm not knowledgeable in real estate other than what I learned from my experiences in the area when I am located. It depends on the market and location. You have to compare what renting will get you for the money vs what buying will get you. For me, buying seemed like a better deal overall when just comparing monthly payments. This is including insurance and taxes. You will need to stay at a house that you buy for at least 5-7 years. You first couple years of payments will go almost entirely towards interest. It takes a while to build up equity. If you can pay more towards a mortgage, do it. You need to have money in the bank already to close. The minimum down payment (at least in my area) is 3.5% for an FHA loan.

I will have to do maintenance myself, but I don't mind fixing what I can fix, and I have a builder's warranties on most things in the house.

Risk is a very large component of the price that a saver will accept to deposit their money in a bank but not the only one. Essentially you are \"\"lending\"\" deposited cash to the bank that you put it in and they will lend it out at a certain risk to themselves and a certain risk to you. By diversifying who they lend to (corporations, home-buyers each other etc.) the banks mitigate a lot of the risk but lending to the bank is still a risky endeavour for the \"\"saver\"\" and the saver accepts a given interest rate for the amount of risk there is in having the money in that particular bank. The bank is also unable to diversify away all possible risk, but tries to do the best job it can. If a bank is seen to take bigger risks and therefore be in greater risk of failing (having a run on deposits) it must have a requisitely higher interest rates on deposits compared to a lower risk bank. \"\"Savers\"\" therefore \"\"shop around\"\" for the best interest rate for a given level of risk which sets the viable interest rate for that bank; any higher and the bank would not make a profit on the money that it lends out and so would not be viable as a business, any lower and savers would not deposit their money as the risk would be too high for the reward. Hence competition (or lack of it) will set the rate as a trade off between risk and return. Note that governments are also customers of the banking industry when they are issuing fixed income securities (bonds) and a good deal of the lending done by any bank is to various governments so the price that they borrow money at is a key determinant of what interest rate the bank can afford to give and are part of the competitive banking industry whether they want to be or not. Since governments in most (westernised) countries provide insurance for deposits the basic level of (perceived) risk for all of the banks in any given country is about the same. That these banks lend to each other on an incredibly regular basis (look into the overnight or repo money market if you want to see exactly how much, the rates that these banks pay to and receive from each other are governed by interbank lending rates called Libor and Euribor and are even more complicated than this answer) simply compounds this effect because it makes all of the banks reliant on each other and therefore they help each other to stay liquid (to some extent). Note that I haven't mentioned currency at all so far but this market in every country applies over a number of currencies. The way that this occurs is due to arbitrage; if I can put foreign money into a bank in a country at a rate that is higher than the rate in its native country after exchange costs and exchange rate risk I will convert all of my money to that currency and take the higher interest rate. For an ordinary individual's savings that is not really possible but remember that the large multinational banks can do exactly the same thing with billions of dollars of deposits and effectively get free money. This means that either the bank's interest rate will fall to a risk adjusted level or the exchange rate will move. Either of those moves will remove the potential for making money for nothing. In this case, therefore it is both the exchange rate risk (and costs) as well as the loan market in that country that set the interest rate in foreign currencies. Demand for loans in the foreign currency is not a major mover for the same reason. Companies importing from foreign entities need cash in foreign currencies to pay their bills and so will borrow money in other currencies to fulfil these operations which could come from deposits in the foreign currency if they were available at a lower interest rate than a loan in local currency plus the costs of exchange but the banks will be unwilling to loan to them for less than the highest return that they can get so will push up interest rates to their risk level in the same way that they did in the market before currencies were taken into account. Freedom of movement of foreign currencies, however, does move interest rates in foreign currencies as the banks want to be able to lend as much of currencies that are not freely deliverable as they can so will pay a premium for these currencies. Other political moves such as the government wanting to borrow large amounts of foreign currency etc. will also move the interest rate given for foreign currencies not just because loaning to the government is less risky but also because they sometimes pay a premium (in interest) for being able to borrow foreign currency which may balance this out. Speculation that a country may change its base interest rate will move short term rates, and can move long term rates if it is seen to be a part of a country's economic strategy. The theory behind this is deep and involved but the tl;dr answer would be the standard \"\"invisible hand\"\" response when anything market or arbitrage related is involved. references: I work in credit risk and got a colleague who is also a credit risk consultant and economist to look over it.

Every £1 you can afford to overpay gives you a guaranteed effective return of 4.00% gross. Yes your monthly mortgage payment will stay the same; however, the proportion of it that's paying off interest every month will be less, and the amount that's actually going into acquiring the bricks and mortar of your home will be greater. So in a sense your returns are \"\"inverted\"\" i.e. because every £1 you overpay is £1 you don't need to keep paying 4% a year to continue borrowing. In your case this return will be locked away for a few more years, until you can remortgage the property. However, compared to some other things you could do with your excess £1s, this is a very generous and safe return that is well above the average rate of UK inflation for the past ten years. Let's compare that to some other options for your extra £1s: Cash savings: The most competitive rate I can currently find for instant access is 1.63% from ICICI. If you are prepared to lock your money away until March 2020, Melton Mowbray Building Society has a fixed rate bond that will pay you 2.60% gross. On these accounts you pay income tax at your marginal rate on any interest received. For a basic rate taxpayer that's 20%. If you're a higher rate taxpayer that means 40% of this interest is deducted as tax. In other words: assuming you pay income tax at one of these rates, to get an effective return of 4.00% on cash savings you'd have to find an account paying: Cash ISAs: these accounts are tax sheltered, so the income tax equation isn't an issue. However, the best rate I can find on a 4 year fixed rate cash ISA is 2.35% from Leeds Building Society. As you can see, it's a long way below the returns you can get from overpaying. To find returns such as that you would have to take a lot more risk with your money – for example: Stock market investments: For example, an index fund tracking the FTSE 100 (UK-listed blue chip companies) could have given you a total return of 3.62% over the last 3 years (past performance does not equal future returns). Over a longer time period this return should be better – historical performance suggests somewhere between 5 to 6% is the norm. But take a closer look and you'll see that over the last six months of 2015 this fund had a negative return of 6.11%, i.e. for a time you'd have been losing money. How would you feel about that kind of volatility? In conclusion: I understand your frustration at having locked in to a long term fixed rate (effectively insuring against rates going up), then seeing rates stay low for longer than most commentators thought. However, overpaying your mortgage is one way you can turn this situation into a pretty good deal for yourself – a 4% guaranteed return is one that most cash savers would envy. In response to comments, I've uploaded a spreadsheet that I hope will make the numbers clearer.

You now owe £1,222.25 less than if you hadn't overpaid. After five years you owe £6,629 less on your mortgage, having overpaid in £6,000 so far. Should you remortgage at this point that £629 is your return so far, and you also have £6k more equity in the property. If you keep going: After 65 months you are paying more capital than interest out of your monthly payment. This takes until 93 months without overpayments. In total, if you keep up £100/month overpayment, you pay £15,533 less interest overall, and end your mortgage six years early. You can play with the spreadsheet inputs to see the effect of different overpayment amounts.

Banks borrow short term and lend long term - so they take money from you for one year, and lend it away as a 20 year mortgage. After a year, they take money for another year. Since short term rates tend to be higher than longer term rates, they make money off the \"\"spread\"\" (or the different between the rate they lend and the rate they borrow). In this scenario, banks should pay higher for longer term deposits, but overall banks realize that interest rates will go up and down, and they don't want to lock the \"\"up\"\" for a longer term. Since banks believe that rates will come down in the 1-2 year period, they offer good rates only till the 1 year period and disincentivize longer term deposits by offering lower rates. If you look at the interbank or money markets, trading of very short term bulk money shows that for the 10-15 day periods, the interest rates being offered are 10% or so, while for one year it's just 9.5%. The market believes that interest rates will go down in the one year time frame - but you never really know since this is just a bunch of people that believe so. Eventually, if rates continue to go up, the demand at the longer term will also go up, because it will become obvious that the rate pressure continues to be strong. If you do want higher rates for the long term, check out State bank of India bonds that are currently trading on the NSE (you can buy them if you have a brokerage account) They are just about as safe as SBI Fixed Deposits, and the rate being offered is around 9.3%, for a 10-15 year term.

For the next few years the it's likely to be (1% + base rate) as interest rates stay low and inflation shoots up. These loans only need to be repaid in proportion to your salary, and if they aren't repaid for long enough (e.g. the holder takes a career break for children) they are written off. So all-in-all, they are pretty good debt to have: low interest rate, and you might not have to repay them ever. It's likely that your mortgage will have a significantly higher rate than the student loan, so you'd be better off reducing your mortgage. Also, the higher deposit might mean you can get a lower interest rate on the whole mortgage because the lender will see you as a lower risk, so the return from \"\"investing\"\" it in your mortgage would be even greater than the raw interest rate. Having the student loan outstanding might make some difference to the \"\"affordability\"\" check for your mortgage payments, but lenders will be very familiar with how they work. Reducing your mortgage payments with the higher deposit should easily counterbalance that. Your own suggestion is to invest the £30K in a \"\"reasonably safe portfolio\"\" making 5%.

It is the interest rate arbitrage. It is a very well explored economic concept, so you can look it up on the Internet, in case you want to know more. 1) Interest rates for the same currency in different countries Basically, as one smart person here pointed out, there is only one price of money in free market economy. It happens, because investors can move their money unrestrictedly anywhere in the World to capitalize on the local interest rates advantage. For instance, if I can take a loan in the USA at 3-4% annual interest and receive 5-6% annual income on my dollar deposit in Russia, I would take a loan in the US and open a deposit in Russia to enjoy a risk free interest rate differential income of 2% (5-6% - 3-4% ~ 2%). So, would any reasonable person. However, in real World very few banks in Russia or anywhere would pay you an an interest rate higher than it can borrow money at. It'd probably lose money if it'd do so. Anyways, the difference between the risk free rate and interest rate on the dollar deposit can be attributed to the risk premium of this particular bank. The higher expected return, the greater risk premium. If there is a positive difference in the interest rates on the dollar deposits in different countries, it will almost entirely accounted for the risk premium. It is generally much riskier to keep money in, say Russian bank, than American. That's why investors want greater return on their dollar deposits in Russian banks than in American. Of course, if you'd want to park your USD in Russian bank you'd also have to consider transaction costs. So, as you may have already guessed, there is no free lunch. 2) Interest rates in different currencies for different countries If we are talking about the interest rates in different sovereign currencies, it is a somewhat similar concept, only there is more risk if you keep money in local currency (risk premium is much higher). Probably, the biggest component of this risk is inflation (that is only attributed to the prices in local currency). For that reason, current interest rates on deposits in Russian Rubles are at 10-12%, but only 1-3% in the US Dollars. An economic concept that discusses this phenomenon in great detail is Interest Rate Parity. Hope this was helpful. P.S. It doesn't look quite realistic that you can get an 8% annual income for USD deposit in Russia with the interest rates in the U.S. being at 1-2%. At present moment, a 30-year mortgage annual interest rate in the US is at ~2-3% and an annual interest rates for dollar deposits in Sberbank (one of the safest Russian banks = very little risk premium) is at 1-3%.

If you don't have a house payment, you have much higher cash flow every month, and your day-to-day living expenses are much lower, so if an illness or job loss happens, you'll be in a much better position to handle it. You should have a good emergency fund in place before throwing extra money at the mortgage so that you can cover the bigger surprises that come along. There is the argument that paying off your mortgage ties up cash that could be used for other things, but you need to be honest with yourself: would you really invest that money at a high enough rate of return to make up your mortgage interest rate after taxes? Or would you spend it on other things? If you do invest it, how certain are you of that rate of return? Paying off the mortgage saves you your mortgage interest rate guaranteed. Finally, there is the more intangible aspect of what it feels like to be completely debt free with no payments whatsoever.

That way you can take the equity from that sale and apply it towards the down payment rather than taking a loan on your retirement account. If something happens and your house doesn't sell for as mush as you think it will, you'll lose out on the gains from the amount you borrow, which will more than offset the interest you are paying yourself. AT WORST, pay off the 401(k) loan the instant your sale closes. Take as much of the remaining equity as you can and start paying down student loans. There are several reasons why they are a higher priority than a mortgage - some are mathematical, some are not. Should I look to pay off student loans sooner (even if I refi at a lower rate of 3.5% or so), or the mortgage earlier ... My thoughts are that the student loans follow me for life, but I can always sell and buy another home So you want this baggage for the rest of your life? How liberating will it be when you get that off your back? How much investing are you missing out on because of student loan payments? What happens if you get lose your license? What if you become disabled? Student loans are not bankruptable, but you can always sell the asset behind a mortgage or car loan. They are worse than credit card debt in that sense. You have no tangible asset behind it and no option for forgiveness (unless you decide to practice in a high-need area, but I don't get the sense that that's your path). The difference in interest is generally only a few payment' worth over 15 years. Is the interest amortized the same as a 15 year if I pay a 30 year mortgage in 15 years? Yes, however the temptation to just pay it off over 30 years is still there. How often will you decide that a bigger car payment, or a vacation, or something else is more important?

The problem with buying a house using cash is that it may leave you cash-poor, forcing you to take out a home equity loan at some point... which may be at a higher rate than the mortgage would have been. On the other hand, knowing that you have no obligation to a lender is quite nice, and many folks prefer eliminating that source of stress. IF you can get a mortgage at a sufficiently low rate, using it to leverage an investment is not a bad strategy. Average historical return on the stock market is around 8%, so any mortgage rate lower than that is a relatively good bet and a rate MUCH lower (as now) is that much better a bet. There is, of course, some risk involved and the obligation to make mortgage payments, and your actual return is reduced by what you're paying on the mortage... but it's still a pretty good deal. As far as investment vehicles: The same answers apply as always. You want a rate of return higher than what you're paying on the mortgage, preferably market rate of return or better. CDs won't do it, as you've found. You're going to have to increase the risk to increase the return. That does mean picking and maintaining a diversified balance of investments and investment types. Working with index funds makes diversifying within a type easy, but you're probably going to want both stocks and bonds, rebalancing between them when they drift too far from your desired mix. My own investments are a specific mix with one each of bond fund, large cap fund, small cap fund, REIT, and international fund. Bonds are the biggest part of that, since they're lowest risk, but the others play a greater part in producing returns on the investments. The exact mix that would be optimal for you depends on your risk tolerance (I'm classified as a moderately aggressive investor), the time horizon you're looking at before you may be forced to pull money back out of the investments, and some matters of personal taste. I've been averaging about 10%, but I had the luxury of being able to ride out the depression and indeed invest during it. Against that, my mortgage is under 4% interest rate, and is for less than 80% of the purchase price so I didn't need to pay the surcharge for mortgage insurance. In fact, I borrowed only half the cost of the house and paid the rest in cash, specifically because leveraging does involve some risk and this was the level of risk I was comfortable with. I also set the duration of the loan so it will be paid off at about the same time I expect to retire. Again, that's very much a personal judgement. If you need specific advice, it's worth finding a financial counselor and having them help you run the numbers. Do NOT go with someone associated with an investment house; they're going to be biased toward whatever produces the most income for them. Select someone who is strictly an advisor; they may cost you a bit more but they're more likely to give you useful advice. Don't take my word for any of this. I know enough to know how little I know.

You take a loan out, but that loan eventually makes its way to other banks as cash deposits, which then are loaned out, and go to other banks, and loaned, etc., so that the economy is \"\"running\"\" on 10x cash, where 1x is in physical cash, and the other 9x is in this deposit-loan-deposit phenomenon. &gt; The issue I see with it is that it becomes exponential growth that is uncapped.

If you have an Excel spreadsheet handy, you can easily model this out in four columns. Label the first row as follows: Deposit, Reserve, Cash Reserve, Loan Amount A2 will be your money supply. For simplicity, put $100. B2, your reserve column, will be 10%. C2 should be =A2 * B2, which will be the cash reserve in the bank. D2 should be A2 - C2, which is the new loan amount extended. A3 should be = D2, as the loans extended from the last step become deposits in the next. B3 = B2. Now, drag the formulas down, say, 500 rows.

I still feel like a novice, but I will give you the benefit of my experience. If you are relying on rental properties for current income versus a long term return you are going to have to do a good job at shopping for bargains to get monthly cash flow versus equity growth that is locked up in the property until you sell it. If you want to pull a lot of cash out of a property on a regular basis you probably are going to have to get into flipping them, which is decidedly not passive investing. Also, it is easy to underestimate the expenses associated with rental properties. Texas is pretty landlord friendly legally, however it does have higher than usual property taxes, which will eat into your return. Also, you need to factor in maintenance, vacancy, tenant turnover costs, etc. It can add up to a lot more than you would expect. If you are handy and can do a lot of repairs yourself you can increase your return, but that makes it less of a passive investment. The two most common rules I have heard for initially evaluating whether an investment property is likely to be cash flow positive are the 1% and 50% rules. The 1% rule says the expected monthly rent needs to be 1% or greater of the purchase price of the house. So your hypothetical $150K/$10K scenario doesn't pass that test. Some people say this rule is 2% for new landlords, but in my experience you'd have to get lucky in Texas to find a house priced that competitively that didn't need a lot of work to get rents that high. The 50% rule says that the rent needs to be double your mortgage payment to account for expenses. You also have to factor in the hassle of dealing with tenants, the following are not going to happen when you own a mutual fund, but are almost inevitable if you are a landlord long enough: For whatever reason you have to go to court and evict a tenant. A tenant that probably lost their job, or had major medical issues. The nicest tenant you ever met with the cutest kids in the world that you are threatening to make homeless.

At a very basic level, I have to ask anyone why they would pay a bank a dollar in order to avoid paying the government 28 - 36 cents depending on your tax rate. After all, one can only deduct interest- not principal. Interest is like rent, it accrues strictly to the lender, not equity. In theory the recipient should be irrelevant. If you have a need to stiff the government, go ahead. Just realize you making a banker three times as happy. Additionally the peace of mind that comes from having a house that no banker can take away from you is, at least for me, compelling. If I have a $300,000 house with no mortgage, no payments, etc. I feel quite safe. Even if my money is tied up in equity, if a serious situation came along (say a huge doctors bill) I always have the option of a reverse mortgage later on. So, to directly counter other claims, yes, I'd rather have $300k in equity then $50k in equity and $225k in liquid assets. (Did you notice that the total net worth is $25k less? And that's even before one considers the cash flow implication of a continuing mortgage. I have no mortgage, and I'm 41. I have a lot of net worth, but the thing that I really like is that I have a roof over my head that no on e can take away from me, and sufficient savings to weather most crises). That said, a mortgage is not about total cost. It is about cash flow. To the extent that a mortgage makes your cash flow situation better, it provides a benefit- just not one that is quantifiable in dollars and cents. Rather, it is a risk/reward situation. By taking a mortgage even when you have the cash, you pay a premium (the interest rate) in order to have your funds available when you need it. A very simple strategy to calculate and/or minimize this risk would be to invest the funds in another investment. If your rate of return exceeds the interest rate minus any tax preference (e.g. 4% minus say a 25% deduction = 3%), your money is better off there, obviously.

OBJECTIVE: We examined the associations of cognitive decline with vitamin B-12 and folate status in a longitudinal cohort study performed from 1993 to 2003 in Oxford, United Kingdom. DESIGN: Cognitive function was assessed with the Mini-Mental State Examination on >/=3 occasions during 10 y and related to serum concentrations of vitamin B-12, holotranscobalamin (holoTC), tHcy, methylmalonic acid (MMA), and folate with the use of linear mixed models in 1648 participants who provided blood in 1995. RESULTS: Cognitive function declined abruptly at younger ages in some participants but remained intact in others until very old age. In multivariate regression analyses after adjustment for established risk factors, concentrations of holoTC (a marker of reduced vitamin B-12 status), tHcy, and MMA predicted cognitive decline, but folate did not. A doubling in holoTC concentrations (from 50 to 100 pmol/L) was associated with a 30% slower rate of cognitive decline (-0.137 to -0.083), whereas a doubling in tHcy (from 10 to 20 micromol/L) or MMA (from 0.25 to 0.50 micromol/L) was associated with >50% more rapid cognitive decline (-0.090 to -0.169) and (-0.104 to -0.169), respectively.

We examined the effect of avenanthramides (Avns), unique polyphenols from oats with anti-inflammatory properties, on COX-2 expression in macrophages, colon cancer cell lines, and on proliferation of human colon cancer cell lines. We found that Avns-enriched extract of oats (AvExO) had no effect on COX-2 expression, but it did inhibit COX enzyme activity and prostaglandin E(2) (PGE(2)) production in lipopolysaccharide-stimulated mouse peritoneal macrophages. Avns (AvExO, Avn-C, and the methylated form of Avn-C (CH3-Avn-C)) significantly inhibited cell proliferation of both COX-2-positive HT29, Caco-2, and LS174T, and COX-2-negative HCT116 human colon cancer cell lines, CH3-Avn-C being the most potent. However, Avns had no effect on COX-2 expression and PGE(2) production in Caco-2 and HT29 colon cancer cells. These results indicate that the inhibitory effect of Avns on colon cancer cell proliferation may be independent of COX-2 expression and PGE(2) production. Thus, Avns might reduce colon cancer risk through inhibition of macrophage PGE(2) production and non-COX-related antiproliferative effects in colon cancer cells. Interestingly, Avns had no effect on cell viability of confluence-induced differentiated Caco-2 cells, which display the characteristics of normal colonic epithelial cells.

There is no convincing scientific evidence that avoidance or delayed introduction of potentially allergenic foods, such as fish and eggs, reduces allergies, either in infants considered at increased risk for the development of allergy or in those not considered to be at increased risk. During the complementary feeding period, >90% of the iron requirements of a breast-fed infant must be met by complementary foods, which should provide sufficient bioavailable iron. Cow's milk is a poor source of iron and should not be used as the main drink before 12 months, although small volumes may be added to complementary foods. It is prudent to avoid both early (<4 months) and late (>or=7 months) introduction of gluten, and to introduce gluten gradually while the infant is still breast-fed, inasmuch as this may reduce the risk of celiac disease, type 1 diabetes mellitus, and wheat allergy. Infants and young children receiving a vegetarian diet should receive a sufficient amount ( approximately 500 mL) of breast milk or formula and dairy products.

We carried out a prospective survey on NCGS in Italian centers for the diagnosis of gluten-related disorders, with the aim of defining the clinical picture of this new syndrome and to establish roughly its prevalence compared with celiac disease. Methods From November 2012 to October 2013, 38 Italian centers (27 adult gastroenterology, 5 internal medicine, 4 pediatrics, and 2 allergy) participated in this prospective survey. A questionnaire was used in order to allow uniform and accurate collection of clinical, biochemical, and instrumental data. Results In total, 486 patients with suspected NCGS were identified in this 1-year period. The female/male ratio was 5.4 to 1, and the mean age was 38 years (range 3–81). The clinical picture was characterized by combined gastrointestinal (abdominal pain, bloating, diarrhea and/or constipation, nausea, epigastric pain, gastroesophageal reflux, aphthous stomatitis) and systemic manifestations (tiredness, headache, fibromyalgia-like joint/muscle pain, leg or arm numbness, 'foggy mind,' dermatitis or skin rash, depression, anxiety, and anemia). In the large majority of patients, the time lapse between gluten ingestion and the appearance of symptoms varied from a few hours to 1 day. The most frequent associated disorders were irritable bowel syndrome (47%), food intolerance (35%) and IgE-mediated allergy (22%). An associated autoimmune disease was detected in 14% of cases. Regarding family history, 18% of our patients had a relative with celiac disease, but no correlation was found between NCGS and positivity for HLA-DQ2/-DQ8. IgG anti-gliadin antibodies were detected in 25% of the patients tested. Only a proportion of patients underwent duodenal biopsy; for those that did, the biopsies showed normal intestinal mucosa (69%) or mild increase in intraepithelial lymphocytes (31%). The ratio between suspected NCGS and new CD diagnoses, assessed in 28 of the participating centers, was 1.15 to 1. Conclusions This prospective survey shows that NCGS has a strong correlation with female gender and adult age.

The association between YE and GD could, however, also be due to common genetic or environmental factors affecting the development of both YE infection and GD.

DESIGN: We first conducted a classical case-control study of individuals with (61) and without (122) GD, and then a case-control study of twin pairs (36) discordant for GD. METHODS: Immunoglobulin (Ig)A and IgG antibodies to virulence-associated Yersinia outer membrane proteins (YOPs) were measured. MAIN OUTCOME MEASURES: The prevalence of YOP IgA and IgG antibodies. RESULTS: Subjects with GD had a higher prevalence of YOP IgA (49%vs. 34%, P = 0.054) and YPO IgG (51%vs. 35%, P = 0.043) than the external controls. The frequency of chronic YE infection, reflected by the presence of both IgA and IgG YOP antibodies, was also higher among cases than controls (49%vs. 33%, P = 0.042). Similar results were found in twin pairs discordant for GD. In the case-control analysis, individuals with GD had an increased odds ratio (OR) of YE infection: IgA 1.84 (95% CI 0.99-3.45) and IgG 1.90 (95% CI 1.02-3.55).

As part of the current state of art in the search for new therapeutic agents, the property of selectivity is a mode of action thought to have a high degree of desirability. Consequently there is a growing activity in this area of research. Selectivity is generally a worthy property in a drug because a drug having high selectivity may have a dramatic effect when there is a single agent that can be targeted against the appropriate molecular-driver involved in the pathogenesis of a disease. An example is chronic myeloid leukemia (CML). CML has a specific chromosomal abnormality, the Philadelphia chromosome, that results in a single gene that produces an abnormal protein Discussion There is a burgeoning understanding of the cellular mechanisms that control the etiology and pathogeneses of diseases. This understanding both enables and motivates the development of drugs that induce a specific action in a selected cell population; i.e., a targeted treatment. Consequently, drugs that can target distinct molecular targets involved in pathologic/pathogenetic processes, or signal-transduction pathways, are being developed. However, in most cases, diseases involve multiple abnormalities. A disease may be associated with more than one dysfunctional protein and these may be out-of-balance with each other. Likewise a drug might strongly target a protein that shares a similar active domain with other proteins. A drug may also target pleiotropic cytokines, or other proteins that have multi-physiological functions. In this way multiple normal cellular pathways can be simultaneously influenced. Long term experience with drugs supposedly designed for only a single target, but which unavoidably involve other functional effects, is uncovering the fact that molecular targeting is not medically flawless. Summary We contend that an ideal drug may be one whose efficacy is based not on the inhibition of a single target, but rather on the rebalancing of the several proteins or events, that contribute to the etiology, pathogeneses, and progression of diseases, i.e., in effect a promiscuous drug. Ideally, if this could be done at minimum drug concentration, side effects could be minimized. Corollaries to this argument are that the growing fervor for researching truly selective drugs may be imprudent when considering the totality of responses; and that the expensive screening techniques used to discover these, may be both medically and financially inefficient.", "title": "Promiscuous drugs compared to selective drugs (promiscuity can be a virtue)" }, { "docid": "MED-4701", "text": "BACKGROUND: Vinegar reduces postprandial glycemia (PPG) in healthy adults.

SUBJECTS: A total of 19 lean, mean age 33±13 years, mean body mass index (BMI) 23.2±2.2 kg m(-2) and 12 OW/OB, mean age 39.5±3 years, mean BMI 28±2.6 kg m(-2), subjects participated in the study, which measured taste thresholds for C18:1, fat perception and hedonic ratings for regular (RF) and lowered-fat (LF) foods before, and following consumption of a high- and low-fat diet. RESULTS: Consumption of the low-fat diet increased taste sensitivity to C18:1 among lean and OW/OB subjects (P<0.05) and increased the subjects ability to perceive small differences in the fat content of custard (P=0.05). Consumption of the high-fat diet significantly decreased taste sensitivity to C18:1 among lean subjects (P<0.05), with no change in sensitivity among OW/OB persons (P=0.609).

CONCLUSION: Alterations in the fat content of the diet modulated taste sensitivity to C18:1 among lean subjects, which was increased following a 4-week period of fat restriction and attenuated following the high-fat diet. The failure of the high-fat diet to alter fatty acid taste thresholds among OW/OB subjects suggests that these individuals were 'adapted' to high-fat exposure, perhaps because of differences in habitual fat consumption. Taken together, these data suggest that excessive dietary fat attenuates nutrient sensing epithelia response in the oral cavity, which could be associated with changes in diet and weight status.", "title": "Recent fat intake modulates fat taste sensitivity in lean and overweight subjects." }, { "docid": "MED-4667", "text": "Cows with isolation of Staphylococcus aureus approximately 1 week after calving and milk yield, somatic cell count (SCC), clinical mastitis (CM), and culling risk through the remaining lactation were assessed in 178 Norwegian dairy herds.

We evaluated the rectal pain threshold at baseline and after conditioning (repetitive rectal painful distention: RRD) in patients with IBS or functional abdominal pain syndrome (FAPS), which is an abdominal pain disorder, and in healthy controls, and determined whether rectal hypersensitivity is a reliable marker for IBS. METHODS: The rectal sensory threshold was assessed by a barostat. First, a ramp distention of 40 ml/min was induced, and the threshold of pain and the maximum tolerable pressure (mmHg) were measured. Next, RRD (phasic distentions of 60-s duration separated by 30-s intervals) was given with a tracking method until the subjects had complained of pain six times. Finally, ramp distention was induced again, and the same parameters were measured. The normal value was defined by calculating the 95% confidence intervals of controls. RESULTS: Five or six of the seven IBS patients showed a reduced rectal pain threshold or maximum tolerable pressure, respectively, at baseline. In all patients with IBS, both thresholds were reduced after RRD load, but they were reduced in none of the patients with FAPS. RRD significantly reduced both thresholds in the IBS group (P < 0.05), but it had no effect in the control or FAPS groups.

Standardized mortality ratios (SMRs) and proportional mortality ratios (PMRs) were estimated, using the US general population for comparison. Results About 45% of the cohort was born after 1949. A total of 788 deaths were recorded; 53% of the decedents were female, and 88% were white. The SMRs for stomach cancer and disorders of the thyroid gland in the cohort as a whole were 2.1 (95% confidence interval [CI], 1.1–3.8) and 6.1 (95% CI 1.3–18.0), respectively.

An emergency fund is a cash account where you keep money for emergencies so you don't need to take on debt like a loan or credit cards. Car breaks down? emergency fund can help pay that. Lose your job? The emergency fund is there to pay rent and for groceries until you're back up an running. There are several schools of thought on how much money should be in your emergency fund, but it boils down to how high your risk assessment is. Typically, the average is to have 3 months in cash available at all times (like in a savings account). It'd be better to have more, but that's a typical goal. You're also asking about investments in the comments. An emergency fund should be readily available. If you already have $10K in savings, set aside what you would need to cover a few months of bills into a cash-ready savings account, then invest the rest. Investments sometimes take time, or have penalties, if you withdraw them. Additionally, as @JoeTaxpayer so correctly pointed out, getting into the habit of maintaining a separate emergency fund helps protect your other investments from becoming a crutch and instead used to save up for larger things like a house or, especially, retirement.

Others have argued that it should be six months of expenses, which is of course easier to achieve. I would recommend against that, partially because it is easier to achieve. The other issue is that people are more prone to underestimate their expenses than their income. Finally, if you base it on your current expenses, then budget for savings and have money left over, you often increase your expenses. Sometimes obviously (e.g. a new car) and sometimes not (e.g. more restaurants or clubs). Income increases are rarer and easier to see. Either way, you can make that six months shorter or longer. Six months is both feasible and capable of handling difficult emergencies. Six years wouldn't be feasible. One month wouldn't get you through a major emergency. Examples of emergencies: Your savings can be in any of multiple forms. For example, someone was talking about buying real estate and renting it. That's a form of savings, but it can be difficult to do withdrawals. Stocks and bonds are better, but what if your emergency happens when the market is down? Part of how emergency funds operate is that they are readily accessible. Another issue is that a main goal of savings is to cover retirement. So people put them in tax privileged retirement accounts. The downside of that is that the money is not then available for emergencies without paying penalties. You get benefits from retirement accounts but that's in exchange for limitations. It's much easier to spend money than to save it. There are many options and the world makes it easy to do. Emergency funds make people really think about that portion of savings. And thinking about saving before spending helps avoid situations where you shortchange savings. Let's pretend that retirement accounts don't exist (perhaps they don't in your country). Your savings is some mix of stocks and bonds. You have a mortgaged house. You've budgeted enough into stocks and bonds to cover retirement. Now you have a major emergency. As I understand your proposal, you would then take that money out of the stocks and bonds for retirement. But then you no longer have enough for retirement. Going forward, you will have to scrimp to get back on track. An emergency fund says that you should do that scrimping early. Because if you're used to spending any level of money, cutting that is painful. But if you've only ever spent a certain level, not increasing it is much easier. The longer you delay optional expenses, the less important they seem. Scrimping beforehand also helps avoid the situation where the emergency happens at the end of your career. It's one thing to scrimp for fifteen years at fifty. What's your plan if you would have an emergency at sixty-five? Or later? Then you're reducing your living standard at retirement.

The first priority is an emergency fund. One of the largest expenses of poor people are short-term loans for emergencies.

Be smart, and pay yourself 10% interest when you do. It's still less than you'd pay for a payday loan, and yet it means that after every emergency you're better prepared for the next event. To get an idea for how much you'd need: you probably own a car. How much would you spend, if you suddenly had to replace it? That should be money you have available. If you think \"\"must\"\" buy a new car, better have that much available. If you can live with a clunker, you're still going to need a few K. Having said that, the next goal after the emergency fund should be savings for the infrequent large purchases. The emergency fund if for the case where your car unexpectedly gets totaled; the saving is for the regular replacement. Again, the point here is to avoid an expensive loan. Paying down a mortgage is not that important. Mortgage loans are cheaper than car loans, and much cheaper than payday loans. Still, it would be nice if your house is paid when you retire.

In the worst-case scenario, let's say you have a financial emergency at the same time the stock market crashes and loses half its value. You could still liquidate the rest and have sufficient funds for 6 months. Am I underestimating the risks of this strategy? That's not worst case scenario though. Worst case scenario would be another 9/11 where the markets are closed for nearly a week and you need the money but can't get the funds converted to cash in the bank that you can use. This is in addition to the potential wait for a settlement in the case of using ETFs if you choose to go that way.

A staggered approach where some cash is kept in house, some in accounts that can easily accessed and some in other investments may make sense though the breakdown would differ depending on how much risk people are willing to take.

This way you will think twice before spending it on a non-emergency.", "title": "" }, { "docid": "254572", "text": "From a budgeting perspective, the emergency fund is a category in which you've budgeted funds for the unexpected. These are things that weren't able to be predicted and budgeted for in advance, or things that exceeded the expected costs. For example you might budget $150 per month for car maintenance, and typically spend some of it while the rest builds up over time for unexpected repairs, so you have a few hundred available for that. But this month your transmission died and you have a $3,000 bill. You'll then fund most of this out of your emergency fund. This doesn't cover where to store that money though, which leads me to my next point. Emergencies are emergencies because they come without warning, without you having a chance to plan. Thefore the primary things you want in an emergency fund account are stability and quick access. You can structure investments to be whatever you think of as safe or stable but you don't want to be thinking about whether it's a good time to sell when you need the money right now. But the bigger problem is access. When you need the funds on a weekend, holiday, anytime outside of market hours, you're not going to be able to just sell some stocks and go to an ATM. This is the reason why it's recommended to have these funds in a checking or savings account usually. The reason I mentioned the budgeting side first is because I wanted to point out that if you're budgeting well, most of the unexpected expenses you have should have been expected in a sense; you can still plan for something without knowing when or if it will happen. So in the example of a car repair, ideally you're already budgeting for possible repairs, if you own a home you're budgeting for things that would go wrong, budgeting for speeding tickets, for surprise out of pocket medical costs, etc. These then become part of your normal budget: they aren't part of the emergency fund anymore. The bright side about budgeting for something unexpected is that you know what that money is for, and do you likely also know how quickly you'll need it. For example you know if you have unexpected medical costs that happen very quickly, you're not likely you need a bag of cash on a moment's notice. So those last two points lead to the fact that your actual emergency fund, the dollars that are for things you simply could not foresee, will be relatively small. A few thousand dollars or so in most cases. If you've got things structured like this, you'll be happy to have a few grand available at a moment's notice. The bulk of the money you would use for other surprise expenses (or things like 6 months of living expenses) is represented in other specific categories and you already know the timeframe in which you need it (probably enough time that it could be invested, risk to taste). In short: by expecting the unexpected, you can sidestep this issue and not worry so much about missed returns on the emergency fund.", "title": "" }, { "docid": "199971", "text": "\"For me, the emergency fund is meant to cover unexpected, but necessary expenses that I didn't budget for. The emergency fund allows me to pay for these things without going into debt. Let's say that my car breaks down, and I don't have any money in my budget for fixing it. I really need to get my car fixed, so I spend the money from my emergency fund. However, cars break down periodically. If I was doing a better job with my budget, I would allocate some money each month into a \"\"car repair/maintenance\"\" category. (In fact, I actually do this.) With my budgeting software, I can look at how much I've spent on car repairs over the last year, and budget a monthly amount for car repair expenses. Even if I do this, I might end up short if I am unlucky. Emergency fund to the rescue! If I'm budgeting correctly, I don't pay any regular bills out of this fund, as those are expected expenses. Car insurance, life insurance, and property tax are all bills that come on a regular basis, and I set aside money for each of these each month so that when the bill comes, I have the money ready to go. The recommended size of an emergency fund is usually listed as \"\"3 to 6 months of expenses.\"\" However, that is just a rough guideline. As you get better with your budget, you might find that you have a lower probability of needing it, and you can let your emergency fund fall to the lower end of the guideline range. The size of my own emergency fund is on the lower end of this scale. And if I have a true crisis (i.e. extended unemployment, severe family medical event), I can \"\"rob\"\" one of my other savings funds, such as my car replacement fund, vacation fund, etc. Don't be afraid to spend your emergency fund money if you need it. If you have an unexpected, necessary expense that you have not budgeted for, use the emergency fund money. However, your goal should be to get to the point where you never have to use it, because you have adequately accounted for all of the expenses that you can reasonably expect to have in the future.\"", "title": "" }, { "docid": "277529", "text": "\"If you think about it, it's really all one big pot of money. The idea behind an \"\"emergency fund\"\" is that you want to make sure your financial life has stability: it's not going to be suddenly driven into the red, below $0. As long as that doesn't happen, you can figure out how to live your life as you want. The reason we separate out an \"\"emergency fund\"\" is to simplify decision making. In theory, every single purchase you make should include a consideration of how it destabilizes you. Every $100 you spend on groceries is $100 you won't be able to bring to bear if you get fired or have a major accident. In practice, this would be a crippling way of thinking about things. You don't know what emergencies can hit you, nor when they will hit. That's why they're \"\"emergencies.\"\" If you had to think about them all the time, it'd be horrible! You would end up simply not thinking about it (like most people), and then the emergency hits when you don't have enough cash to stay solvent. The purpose of an \"\"emergency fund\"\" is to help make these decisions easier. If you have money set aside for \"\"emergencies\"\" that you only have to think about every now and then, you can make the decisions in the rest of your financial life without too much concern for them. You don't have to worry about that $100 in groceries because you are confident that if an emergency hits, that $100 won't be the straw that broke the camel's back because you have reserves to draw on. So you should define an \"\"emergency fund\"\" in a way which is most helpful for you to remain stable and solvent without having to fret about it too much. For most people, the criteria for tapping that fund is very high, because the goal is to not have to think about it all that much. If you wanted to, you could feel free to lump those \"\"medium predictability\"\" items into the emergency fund, but it just means you have to spend more time and effort thinking about the state of the fund. Every medium predictability purchase has to come with the thought process \"\"what is the state of the emergency fund? Could this purchase meaningfully destabilize my ability to handle emergencies?\"\" Your emergency fund might yo-yo under these extra purchases, which could force you to think about the state of your emergency fund for normal purchases. That'd be bad. Different people might want to think about things different ways. I'm a big-picture guy, so I prefer to think about all of my assets as one big account when I make a lot of my decisions. My wife, on the other hand, prefers not to have to think that way when she makes her purchases. For her, having a very discrete \"\"emergency fund\"\" has great value. For me, it has less. So when I look at the finances, I choose to lump the emergency funds in with, say, the funds to re-do our backyard (something we are looking at doing over the next 2-5 years). For me, that is the most natural way to deal with analyzing the risks -- I just have to be aware of how backyard purchases interact with our safety net. My wife prefers to keep those funds separate in her head, so that she can look at how to spend money on the backyard without thinking about how it affects our emergency readiness. While complicated, it shows that even within a household, it's possible to think about emergency funding two different ways. (it causes minimal headaches, though a fair bit of book-keeping) So define \"\"emergency fund\"\" however suits you and your life best. However, practically speaking, most people find it desirable to not put those medium predictability purchases into the same bucket as emergencies. Those that do find it desirable to put them in the same bucket typically have a personal reason for why that suits their needs better.\"", "title": "" }, { "docid": "451501", "text": "Is my financial status OK? If not, how can I improve it? I'm going to concentrate on this question, particularly the first half. Net income $4500 per month (I'm taking this to be after taxes; correct me if wrong). Rent is $1600 and other expenses are up to $800. So let's call that $2500. That leaves you $2000 a month, which is $24,000 a year. You can contribute up to $18,000 a year to a 401k and if you want to maintain your income in retirement, you probably should. The average social security payment now is under $1200. You have an above average income but not a maximum income. So let's set that at $1500. You need an additional income stream of $900 a month in retirement plus enough to cover taxes. Another $5500 for an IRA (probably a Roth). That's $23,500. That leaves you $500 a year of reliable savings for other purposes. Another $5500 for an IRA (probably a Roth). That's $23,500. That leaves you $500 a year of reliable savings for other purposes. You are basically even. Your income is just about what you need to cover expenses and retirement. You could cover a monthly mortgage payment of $1600 and have a $100,000 down payment. That probably gets you around a $350,000 house, although check property taxes. They have to come out of the $1600 a month. That doesn't seem like a lot for a Bay area house even if it would buy a mansion in rural Mississippi. Perhaps think condo instead. Try to keep at least $15,000 to $27,000 as emergency savings. If you lose your job or get stuck with a required expense (e.g. a major house repair), you'll need that money. You don't have enough income to support a car unless it saves you money somewhere. $500 a year is probably not going to cover insurance, parking, gas, and maintenance. It's possible that you could tighten up your expenses, but in my experience, people are more likely to underestimate their expenses than overestimate. That's why I'm saying $2500 (a little above the high end) rather than $2000 (your low end estimate). If things are stable, wait a year and evaluate. Track your actual spending. Ask yourself if you made any large purchases. Your budget should include an appliance (TV, refrigerator, washer/dryer, etc.) a year. If you're not paying for that now (included in rent?), then you need to allow for it in your ownership budget. I do not consider an ESPP to be a reliable investment vehicle. Consider the Enron possibility. You wake up one day and find out that there is no actual money. Your stock is now worthless. A diversified portfolio can survive this. If you lose your job and your investment, you'll be stuck with just your savings. Hopefully you didn't just tie them up in a house that you might have to sell to take your next job in a different location. An ESPP might work as savings for the house. If something goes wrong, don't buy the house. But it's not retirement or emergency savings. I would say that you are OK but could be better. Get your retirement savings started. That does two things. One, it gives you money for retirement. Two, it keeps you from having extra money now when it is easy to develop expensive habits. An abrupt drop from $4500 in spending to $1200 will hurt. A smooth transition from $2500 to $2500 is what you would like to see. You are behind now, but you have the opportunity to catch up for a few years. Work out how much you'll get from Social Security and how much you need to cover your typical expenses with the occasional emergency. Expect high health care costs in retirement. Medicare covers a lot but not everything, and health care is only getting more expensive. Don't forget to assume higher taxes in the future to help cover that expense and the existing debt. After a few years of catch up contributions, work out your long term plan assuming a reasonable real (after inflation) rate of return. If you can reduce the $23,500 in retirement contributions then, that's OK. But be pessimistic. Most people overestimate good things and underestimate bad things. It's much better to have extra than not enough. A 401k comes with an administrator and your choice of mutual funds. Try for diversification. Some money in bonds (25% to 30%). The remainder in stocks. Look for index funds. Try for a mix of value and growth, as they'll do better at different times. As you approach retirement, you can convert some of that into shorter term, lower yield investments. The rough rule of thumb is to have two to five years of withdrawals in short term investments like money market funds. But that's more than twenty years off. You have more choices with an IRA. In particular, you can choose your own administrator. But I'd keep the same stock/bond mix and stick to index funds if you're not interested in researching the more complex options. You may want to invest your IRA in a growth fund and your 401k in value funds and bonds. Then balance the stock/bond mix across both. When you invest each year, look at the underrepresented funds and add the most to them. So if bonds had a bad year and didn't keep pace, invest in bonds. They're probably cheap. You don't want to rebalance frequently, but once a year might be a good pace. That's about how often you should invest in an IRA, so that can be a good time.

If you decide not to pay for contents insurance, calculate what it would cost you if there is a fire in your apartment and you would have to replace everything.

Priority 3: Retirement. Unless there will be some serious retirement reforms in the next 40 years (and I would not bet on that!), the government-provided pension will not be enough to cover your lifestyle cost. If you don't want to suffer from poverty as a senior citizen you will have to build up a retirement plan now. Check which options your company provides (\"\"Betriebliche Altersvorsorge\"\") and what retirement options you have which give you free money from the government (\"\"Riester-Rente\"\").

Paying of a mortgage is just like paying rent - but with the difference that the money you pay every month isn't spent. Most of it (minus interest and building maintenance costs) stays your capital! At one point you will have paid it off and then you never have to pay rent in your life. It even secures the financial future of your children and grandchildren, who will inherit your home. But few banks will give you a good interest rate if you have no own capital at all. So you should start saving money now. Invest a few hundred € every month in a long-term portfolio.

Not enough to cover too much in case of job loss, but enough to cover the busted transmission, the broken water heater, etc. this is still more than many people have saved up, but it's a worthy goal.

But even if you just have all your money in one savings account and you mentally tell yourself, \"\"I don't want to ever let the balance drop below $10,000, just so I have a safety cushion\"\" then you are effectively designating that $10,000 as an emergency fund.\"", "title": "" }, { "docid": "244692", "text": "\"One can generalize on Traditional vs Roth flavors of accounts, I suggest Roth for 15% money and going pretax to avoid 25% tax.

I'm in favor of doing what let's you sleep well.

There's an ongoing debate of \"\"credit card as emergency fund.\"\" No, I don't claim that your cards should be considered an emergency fund, per se, but I would prioritize knocking off the 18% debt as a high priority. Once that crazy interest debt is gone, fund the ER, and find a balance for savings and the next level ER, the 6-9mo of expenses one. One can choose to fund a Roth IRA, but keep the asset out of retirement calculations. It's simply an emergency account returning tax free interest, and if never used, it eventually is retirement money. A Roth permits withdrawal of deposited funds with no tax or penalty, just tracking it each year. This actually rubs some people the wrong way as it sounds like tapping your retirement account for emergencies. For my purpose, it's a tax free emergency fund. Not retirement, unless and until you are saving so much in the 401(k) you need more tax favored retirement money. I wrote an article some time ago, the Roth Emergency Fund which went into a bit more detail. Last - keep in mind, this is my opinion. I can intelligently argue my case, but at some point, it's up to the individual to do what feels right. Paying 18% debt off a bit slower, say 4 years instead of 3, in favor of funding the matched 401(k), to me, you run the numbers, watch the 401(k) balance grow by 2X your pretax deposits, and see that in year 3, your retirement account is jump-started and far, far more than your remaining 18% cards.

You will be paying so little tax that there will be essentially no benefit to making the contributions, and you'll pay tax when they come out.

For you, that would be $1500. If you put $100 a month aside, it will take over a year to have your emergency fund. It's easy to argue that you should pick a higher pace, so as to have your emergency money in place sooner. However, the \"\"emergencies\"\" usually cited are things like home repair, car repair, needing to replace your car, and so on. Since you are renting your home and don't have a car, these emergencies aren't going to happen to you. Ask yourself, if your home was destroyed, and you had to replace all your clothes and possessions (including furniture), how much would you need? (Keep in mind any insurance you have.) The only emergency expense I can't guess about is health costs, because I live in Canada. I would be tempted to tell you to get a credit card with a $2000 limit and consider that your emergency fund, just because grad student living is so tight to the bone (been there, and 25 years ago I had $1200 a month, so it must be harder for you now.)

Delaying your graduation by a few months because you're not mentally sharp due to hunger or tiredness will be a far bigger economic hit than not having saved $200 a month for 2 or 3 years.

You know what you're likely to earn when you graduate, right?\"", "title": "" }, { "docid": "120706", "text": "I like the way you framed this question. There is no single right answer for what to do with your savings, but there are some choices that are wrong in the sense that they are dominated by other choices you could make. Of the choices you listed, there are two that fall into that category. The ones that seem like a bad idea to me are: Putting it into your Roth 401(k). You can't do this directly anyhow, but you could do it indirectly by increasing your contributions and using the growth fund to cover the hole in your budget, but that's a lot of work for a relatively small gain. You would essentially be exchanging one long-term investment for another long-term investment. You would pay capital gains taxes on the investment when you sell it today, in order to not pay taxes on its earnings when you eventually withdraw it. There is some benefit there, but it's a long way off, not that large, and probably not worth the effort. Things that might change your mind: If your 401(k) was a traditional 401(k) (paying tax at capital gains rate today to get a deduction at your normal income rate is likely to be a win). You're not contributing enough to get the full company match (always try to get that match if you can). Putting it into your emergency fund. Once again, you are likely to pay capital gains tax if you do this, and you will be putting it into an investment that is likely to get a lower return than your current one. It isn't really necessary to incur these costs, since if you encounter an emergency that you can't cover with your existing emergency fund, you could always liquidate the growth fund then, when you know you need it. Now, a growth fund is going to be more volatile than what you would normally want for an emergency fund, but the risk isn't that bad, if you think about it. Say your emergency comes up and you find that the growth fund is down 20% (which would be a pretty horrible run). That's $600 less that you have to deal with the situation. Keep in mind that you already have $2000 (and building) in your current emergency fund. Is that $600 going to make the difference between meeting the need and not? It's not likely. Better to leave the investment where it is and keep building your emergency fund week by week. Things that might change your mind: Your level of risk aversion (if having that money in a more risky investment is keeping you up at night, move it). You face significant job uncertainty (if you have reason to think your job is at risk, it might be a good idea to top off that emergency fund sooner rather than later.) Your other two choices both seem like solid options under the right circumstances. If it were me, I'd leave the investment in place rather than use it to pay off the student loan. The investment is likely (though of course not guaranteed) to earn more than the interest rate even on the highest-rate loan, especially when you consider that the interest on the student loan is probably tax deductible. Moreover, the size of the investment isn't enough to fully repay the loan, so putting it toward the loan won't even improve your cash flow for some time to come. However, there is always a chance that the investment will perform poorly and some people prefer the guaranteed return from paying off the loan. It depends on your personal risk tolerance. The one thing I would recommend is to think of putting the money toward the loan not as a debt repayment, but as a fixed-income investment with a yield equal to your loan's interest rate. If you would still consider buying it then, then go ahead. If not, then stick with what you've got. In my experience people get way too emotional about debt; try to take that emotion out of your decision making if you can.", "title": "" }, { "docid": "178303", "text": "\"Some thoughts: 1) Do you have a significant emergency fund (3-6 months of after-tax living expenses)? If not, you stand to take a significant loss if you have an unexpected need for cash that is tied up in investments. What if you lose/hate your job or your car breaks down? What if a you want to spend some time with a relative or significant other who learns they only have a few months to live? Having a dedicated emergency fund is an important way to avoid downside risk. 2) Lagerbaer has a good suggestion. Given that if you'd reinvested your dividends, the S&P 500 has returned about 3.5% over the last 5 years, you may be able to get a very nice risk-free return. 3) Do you have access to employer matching funds, such as in a 401(k) at work? If you get a dollar-for-dollar match, that is a risk-free pre-tax 100% return and should be a high priority. 4) What do you mean by \"\"medium\"\" volatility? Given that you are considering a 2/3 equity allocation, it would not be at all out of the realm of possibility that your balance could fall by 15% or more in any given year and take several years to recover. If that would spook you, you may want to consider lowering your equity weights. A high quality bond fund may be a good fit. 5) Personally, I would avoid putting money into stocks that I didn't need back for 10 years. If you only want to tie your money up for 2-5 years, you are taking a significant risk that if prices fall, you won't have time to recover before you need your money back. The portfolio you described would be appropriate for someone with a long-term investment horizon and significant risk tolerance, which is usually the case for young people saving for retirement. However, if your goals are to invest for 2-5 years only, your situation would be significantly different. 6) You can often borrow from an investment account to purchase a primary residence, but you must pay that amount back in order to avoid significant taxes and fees, unless you plan to liquidate assets. If you plan to buy a house, saving enough to avoid PMI is a good risk-free return on your money. 7) In general, and ETF or index fund is a good idea, the key being to minimize the compound effect of expenses over the long term. There are many good choices a la Vanguard here to choose from. 8) Don't worry about \"\"Buy low, sell high\"\". Don't be a speculator, be an investor (that's my version of Anthony Bourdain's, \"\"don't be a tourist, be a traveler\"\"). A speculator wants to sell shares at a higher price than they were purchased at. An investor wants to share in the profits of a company as a part-owner. If you can consistently beat the market by trying to time your transactions, good for you - you can move to Wall Street and make millions. However, almost no one can do this consistently, and it doesn't seem worth it to me to try. I don't mean to discourage you from investing, just make sure you have your bases covered so that you don't have to cash out at a bad time. Best of luck! Edit Response to additional questions below. 1) Emergency fund. I would recommend not investing in anything other than cash equivalents (money market, short-term CDs, etc.) until you've built up an emergency fund. It makes sense to want to make the \"\"best\"\" use of your money, but you also have to account for risk. My concern is that if you were to experience one or more adverse life events, that you could lose a lot of money, or need to pay a lot in interest on credit card debt, and it would be prudent to self-insure against some of those risks. I would also recommend against using an investment account as an emergency fund account. Taking money out of investment accounts is inefficient because the commissions/taxes/fees can easily eat up a significant portion of your returns. Ideally, you would want to put money in and not touch it for a long time in order to take advantage of compounding returns. There are also high penalties for early disbursements from retirement funds. Just like you need enough money in your checking account to buy food and pay the rent every month, you need enough money in an emergency fund to pay for things that are a real possibility, even if they are less common. Using a credit card or an investment account is a relatively expensive way to do this. 2) Invest at all? I would recommend starting an emergency fund, and then beginning to invest for retirement.

I've usually heard it expressed as \"\"3 to 6 months,\"\" but everyone has a different idea of exactly how big it should be. The purpose of the fund is to give you enough cash to be able to pay for unexpected expenses that have come up that you have not budgeted for without you having to borrow money to pay for them. To figure out how big this fund should be, we look at the worst case scenario. Suppose that you lost your job tomorrow. What would you do? Cut your expenses. You'd probably be much more careful how you spend money. Secure health insurance. This would be done by either continuing your employer's policy with COBRA, or by purchasing your own insurance, likely through the Obamacare/ACA market. Keep in mind that most likely your employer is paying for a portion of your insurance now, so this expense will go up quite a bit no matter which option you choose. Look for another job. You'd probably begin your search for a new job immediately. The size of your emergency fund determines how long you will be able to go without income before you need to start a new job. Regarding cutting your expenses, it is up to you how much you would cut. There are things that are easy to cut temporarily (or permanently), such as restaurants, entertainment expenses, vacations, etc. You would probably stop retirement investing until you have income again. The more you cut, the longer your emergency fund would last. Things you don't want to cut are necessities, like housing, groceries, utilities, transportation, etc. I would also include health insurance in this list. Certainly, if you have a pre-existing condition, you do not want to let your health insurance coverage lapse. Your employability is also a factor. If you believe that you would have an easy time finding similar employment to what you have now, your emergency fund might not need to be quite as big as someone who believes they would have a harder time finding another job.\"", "title": "" } ]

Is building a corporation a good option?

In fact, you'll face the problem of double taxation, and since you must pay yourself a reasonable salary, if your corporation doesn't earn much to give you as dividend after the salary, and/or your tax bracket is low, you'll in fact may end up paying more taxes. Also there's a lot of bureaucracy involved in managing a corporation. Liability on the other hand is important, and what's more important - is asset separation and limiting the liability to the corporation assets, keeping your personal assets safe. To achieve that, you don't have to create a corporation, but you can create a Limited Liability Company (LLC). LLC are disregarded entities for tax purposes (i.e.: you won't have to pay taxes twice, only once as a sole proprietor/partner), but provide the liability limitation and asset separation. LLC's are much less formal, and require much less paperwork reducing the risk of corporate veil piercing because of non-compliance.

You should be able to weigh the tax savings and liability protection against the extra costs and hassle, and see which way the scales tip.

If your average startup started issuing lots of stock and devaluing existing shares significantly then I would expect it would be harder to find investors willing to watch as their investment dwindled. But if you are issuing a limited amount stock to get leverage to grow bigger then it is worth it. In the .com bubble there were quite a few companies that just issued stock to buy other companies. Eventually most of these companies got delisted because they diluted them selves to much when they were overvalued. Any company not just a startup can dilute its shares. Many if not most major companies issue stock to raise capital. This capital is then generally used to build the business further and increase the value of all shares.

If you are in a margin account, regulations permit the trading of unsettled funds without affecting margin requirements, so your funds in effect are available immediately after trading but aren't considered margin loans. Some strict brokers will even restrict the amount of uncleared margin funds you can trade with (Scottrade used to be hyper safe and was the only online discount broker that did this years ago); others will allow you to withdraw a large percentage of your funds immediately (I think E*Trade lets you withdraw up to 90% of unsettled funds immediately).

Thus, there may be some people that would rather invest in stocks than hold their investments in lower-yielding options.

Housing market investors are betting that these year to year revenue losses will ultimately be made up in a big capital gain: for which individuals get a huge tax break that is also not available to corporations. Capital gains are not guaranteed. Australia has benefited from 25+ years of economic, employment and wages growth: a result of good government planning, strong corporate governance and a fair slice of luck. If this were to end housing prices would plateau at best and crash at worst. A person who has negative cash flow investments has to sell them urgently if they lose their job. A glut of mortgagee sales and property prices could easily come off 20-30%. Rental yields on residential property in Sydney are about 4% with a capital gain of currently 10% but this has been flat or negative within the last 5 years and no doubt will be again within the next 5. Rental yields for residential property are constrained by mortgage rates: if it significantly cheaper to buy then to rent, why would anyone rent? In contrast, industrial and commercial property gets a yield of about 7% and gets exactly the same capital gain. This is because land is land and if the price of industrial land doesn't grow at the same rate as the residential land next door eventually one will be converted into the other. Retail rentals are even higher. In addition commercial tenants are responsible for more outgoings and have fewer legal rights than residential tenants. Further, individual residential properties are horribly illiquid and have large transaction costs. While it is possible to bundle them up into property trusts so that units can be sold on the stock exchange it is far more common to do this with office and retail buildings. This is what companies like Westfield and AMP Capital do. Notwithstanding, heavily geared property trusts can get into deep water because of the illiquid nature of property as the failure of Centro illustrates.

A tax refund is the payment you receive from the government if your payments into the tax system exceeded your obligations. As others have mentioned, if an extra $2K in income generated $5K in taxes, chances are your return was prepared incorrectly. The selection of an appropriate entity type for your business depends a lot on what you expect to see over the next several years in terms of income and expenses, and the extent to which you want or need to pay for fringe benefits or make pretax retirement contributions from your business income. There are four basic flavors of entity which are available to you: Sole proprietorship. This is the simplest option in terms of tax reporting and paperwork required for ongoing operations. Your net (gross minus expenses) income is added to your wage income and you'll pay tax on the total. If your wage income is less than approximately $100K, you'll also owe self-employment tax of approximately 15% in addition to income tax on your business income. If your business runs at a loss, you can deduct the loss from your other income in calculating your taxable income, though you won't be able to run at a loss indefinitely. You are liable for all of the debts and obligations of the business to the extent of all of your personal assets. Partnership. You will need at least two participants (humans or entities) to form a partnership. Individual items of income and expense are identified on a partnership tax return, and each partner's proportionate share is then reported on the individual partners' tax returns. General partners (who actively participate in the business) also must pay self-employment tax on their earnings below approximately $100K. Each general partner is responsible for all of the debts and obligations of the business to the extent of their personal assets. A general partnership can be created informally or with an oral agreement although that's not a good idea. Corporation. Business entities can be taxed as \"\"S\"\" or \"\"C\"\" corporations. Either way, the corporation is created by filing articles of incorporation with a state government (doesn't have to be the state where you live) and corporations are typically required to file yearly entity statements with the state where they were formed as well as all states where they do business. Shareholders are only liable for the debts and obligations of the corporation to the extent of their investment in the corporation. An \"\"S\"\" corporation files an information-only return similar to a partnership which reports items of income and expense, but those items are actually taken into account on the individual tax returns of the shareholders. If an \"\"S\"\" corporation runs at a loss, the losses are deductible against the shareholders' other income. A \"\"C\"\" corporation files a tax return more similar to an individual's. A C corporation calculates and pays its own tax at the corporate level. Payments from the C corporation to individuals are typically taxable as wages (from a tax point of view, it's the same as having a second job) or as dividends, depending on how and why the payments are made. (If they're in exchange for effort and work, they're probably wages - if they're payments of business profits to the business owners, they're probably dividends.) If a C corporation runs at a loss, the loss is not deductible against the shareholders' other income. Fringe benefits such as health insurance for business owners are not deductible as business expenses on the business returns for S corps, partnerships, or sole proprietorships. C corporations can deduct expenses for providing fringe benefits. LLCs don't have a predefined tax treatment - the members or managers of the LLC choose, when the LLC is formed, if they would like to be taxed as a partnership, an S corporation, or as a C corporation. If an LLC is owned by a single person, it can be considered a \"\"disregarded entity\"\" and treated for tax purposes as a sole proprietorship. This option is not available if the LLC has multiple owners. The asset protection provided by the use of an entity depends quite a bit on the source of the claim. If a creditor/plaintiff has a claim based on a contract signed on behalf of the entity, then they likely will not be able to \"\"pierce the veil\"\" and collect the entity's debts from the individual owners. On the other hand, if a creditor/plaintiff has a claim based on negligence or another tort-like action (such as sexual harassment), then it's very likely that the individual(s) involved will also be sued as individuals, which takes away a lot of the effectiveness of the purported asset protection. The entity-based asset protection is also often unavailable even for contract claims because sophisticated creditors (like banks and landlords) will often insist the the business owners sign a personal guarantee putting their own assets at risk in the event that the business fails to honor its obligations. There's no particular type of entity which will allow you to entirely avoid tax.

That means that the index is calculated by adding up the prices of the constituent stocks and dividing by a constant, the \"\"Dow divisor\"\". (The value of the Dow divisor is adjusted from time to time to maintain continuity when there are splits or changes in the roster.) This has the curious effect of giving a member of the index influence proportional to its share price. That is, if a stock costing $100 per share goes up by 1%, that will change the index by 10 times as much as if a stock costing $10 per share goes up by the same 1%. Now look at the price of Google. It's currently trading at just a whisker under $700 per share. Most of the other stocks in the index trade somewhere between $30 and $150, so if Google were included in the index it would contribute between 5 and 20 times the weight of any other stock in the index. That means that relatively small blips in Google's price would completely dominate the index on any given day. Until June of 2014, Apple was in the same boat, with its stock trading at about $700 per share. At that time, Apple split its stock 7:1, and after that its stock price was a little under $100 per share. So, post-split Apple might be a candidate to be included in the Dow the next time they change up the components of the index. Since the Dow is fixed at 30 stocks, and since they try to keep a balance between different sectors, this probably wouldn't happen until they drop another technology company from the lineup for some reason. (Correction: Apple is in the DJIA and has been for a little over a year now. Mea culpa.) The Dow's price-weighting is unusual as stock indices go. Most indices are weighted by market capitalization. That means the influence of a single company is proportional to its total value. This causes large companies like Apple to have a lot of influence on those indices, but since market capitalization isn't as arbitrary as stock price, most people see that as ok. Also, notice that I said \"\"company\"\" and not \"\"stock\"\". When a company has multiple classes of share (as Google does), market-cap-weighted indices include all of the share classes, while the Dow has no provision for such situations, which is another, albeit less important, reason why Google isn't in the Dow. (Keep this in mind the next time someone offers you a bar bet on how many stocks are in the S&P 500. The answer is (currently) 505!) Finally, you might be wondering why the Dow uses such an odd weighting in its calculations. The answer is that the Dow averages go back to 1896, when Charles Dow used to calculate the averages by hand. If your only tools are a pencil and paper, then a price-weighted index with only 30 stocks in it is a lot easier to calculate than a market-cap-weighted index with hundreds of constituents.

This lack of flexibility means that some of the key levers of international finance are compromised, for example a weak economy can't float its currency to improve exports.

But the stock market is actually positive-sum, since companies are delivering part of their profits to their stockholder owners. This moves the center of the bell curve up a bit from break-even, historically to about +8%.

Large cap stocks, small cap stocks, bonds, and real estate (in the form of REITs) each have different baseline risk/return curves, and move in different ways in response to news, so maintaining a selected ratio between these buckets and adding the resulting curves together is one simple way to make fairly predictable adjustments to the width (and centerline) of the total bell curve. If you think you can do better than this, go for it. But index funds have been outperforming professionally managed funds (after the management fees are accounted for), and unless you are interested in spending a lot of time researching and playing with your money the odds of your doing much better aren't great unless you're willing to risk doing much worse.

There are enough additional costs associated with home-ownership (down-payment, insurance, repairs) relative to more traditional investments to argue against a primary residence being an investment. Your question didn't indicate when and where you bought your home, the type of home (single-family, townhouse, or condo) the nature of your mortgage (fixed-rate or adjustable rate), or your interest rate, but since you're in your mid-20s, I'm guessing you bought after the crash. If that's the case, your odds of making a profit if/when you sell your home are higher than they would be if you bought in the 2006/2007 time-frame. This is no guarantee of course. Given the amount of housing stock still available, housing prices could still fall further. While it is possible to lose money in all sorts of investments, the illiquid nature of real estate makes it a lot more difficult to limit your losses by selling. If preserving principal is your objective, money market funds and treasury inflation protected securities are better choices than your home.

A transaction of just 1 share will post a new price even if just seconds earlier 100,000 shares traded for a different price. (Ok, unrealistic example, but you get my point.)

Instead, he'll buy the 50 @ .22, then 80 @ .23, then 100 @ .30, etc. Because your order is so large compared to the unmatched orders, your market order will get matched a bunch of the unmatched orders on the sell side, and each match will notch the posted price up a bit.

The time value and option value are tied to the value of the underlying. The value of the underlying (stock) is quite influenced by volatility, the possible price movement in a given span of time. Thirty days of volatility has a much broader spread of values than two days, since each day benefits from the possible price change of the prior days. So if a stock could move up to +/- 1% in a day, then compounded after 5 days it could be +5%, +0%, or -5%. In other words, this is compounded volatility. Less time means far less volatility, which is geometric and not linear. Less volatility lowers the value of the underlying. See Black-Scholes for more technical discussion of this concept. A shorter timeframe until option expiration means there are fewer days of compounded volatility. So the expected change in the underlying will decrease geometrically. The odds are good that the price at T-5 days will be close to the price at T-0, much more so than the prices at T-30 or T-90. Additionally, the time value of an American option is the implicit put value (or implicit call). While an \"\"American\"\" option lets you exercise prior to expiry (unlike a \"\"European\"\" option, exercised only at expiry), there's an implicit put option in a call (or an implicit call in a put option). If you have an American call option of 60 days and it goes into the money at 30 days, you could exercise early. By contract, that stock is yours if you pay for it (or, in a put, you can sell whenever you decide). In some cases, this may make sense (if you want an immediate payoff or you expect this is the best price situation), but you may prefer to watch the price. If the price moves further, your gain when you use the call may be even better. If the price goes back out of the money, then you benefited from an implicit put. It's as though you exercised the option when it went in the money, then sold the stock and got back your cash when the stock went out of the money, even though no actual transaction took place and this is all just implicit. So the time value of an American option includes the implicit option to not use it early. The value of the implicit option also decreases in a nonlinear fashion, since the value of the implicit option is subject to the same valuation principles.

This may seem odd as a futures contract sounds like you are betting on the future price of the index, but remember that the current price already includes the expectations of future earnings as well! There is actually a fairly simple formula for the price of a futures contract (note the link is for forward contracts which are very similar but slightly more simple to understand). Note, that if you are given the current price of the underlying the futures price depends essentially only on the interest rate and the dividends paid during the length of the futures contract. In this case the dividend rate for the S&P500 is higher than the prevailing interest rate so the futures price is lower than the current price. It is slightly more complicated than this as you can see from the formula, but that is essentially how it works. Note, this is why people use futures contracts to mimic other exposures. As the price of the future moves (pretty much) in lockstep with the underlying and sometimes using futures to hedge exposures can be cheaper than buying etfs or using swaps. Edit: Example of the effect of dividends on futures prices For simplicity, let's imagine we are looking at a futures position on a stock that has only one dividend (D) in the near term and that this dividend happens to be scheduled for the day before the futures' delivery date. To make it even more simple lets say the price of the stock is fairly constant around a price P and interest rates are near zero. After the dividend, we would expect the price of the stock to be P' ~ P - D as if you buy the stock after the dividend you wouldn't get that dividend but you still expect to get the rest of the value from additional future cash flows of the company. However, if we buy the futures contract we will eventually own the stock but only after the dividend happens. Since we don't get that dividend cash that the owners of the stock will get we certainly wouldn't want to pay as much as we would pay for the stock (P). We should instead pay about P' the (expected) value of owning the stock after that date. So, in the end, we expect the stock price in the future (P') to be the futures' price today (P') and that should make us feel a lot more comfortable about what we our buying.

Even over the last decade, when stocks \"\"went nowhere\"\", you still came out ahead through the dividend payments. It was just at an unsatisfactory rate of return. Also \"\"the market\"\" consists of a lot more than just stocks. Corporate bonds are a big market and I always recommend people to look at bonds. If you cannot judge whether a company is credit worthy, how can you invest in the common stock? I've made a lot more money myself in the bond market than in the stock market. However, for many stocks, they do look a lot like ponzi schemes. This is true, in particular, with many of the tech stocks (Cuban was a tech investor, so that is probably where his sentiment is coming from). You have many of these companies that create great products. However, they never have positive cash flow because all the money is spent to develop new products. As the share price goes up, the company issues new shares to fund research, stock options to employees to enrich them, etc. However, eventually, they run into a string of bad research that do not yield a new product and the share price plunges. Perhaps the company goes bankrupt. So you have a company that developed great products, but the shareholders never got a penny in dividends and the final shareholders have paper worth zero. Take a look at Research in Motion for example. Creating the Blackberry has to be one of the biggest successes in tech over the last decade. However, has the shareholders gotten any richer? Only if they traded amongst themselves, nobody got a dividend. What happened to the many billions of dollars they made during the peak popularity years of Blackberry? It went to executives, employees, and was squandered on development that did not effectively defend the phone's dominant market position. Now the stock price is back down to the pre-prime years, and if a shareholder held onto it throughout the entire period, he would not have received a single penny. And this is a profitable enterprise, things look even more bizarre when you start looking at the tech companies that have NEVER had a positive earnings quarter and no plans to ever have positive earnings (something like Pandora comes to mind). Often, management at these more bizarre companies run the company as a toy - to play with their own ideas and to issue themselves stock as compensation. And of course, they sell a lot of the stock to cash in before they delve into the next risky venture. They have no intention of ever enriching anybody who holds into the stock in the long run. If for some reason they make money, they will put it all into their next toy project until one of them fails and wipes everything out. If you invest in a profitable business with reasonable management, you will generally come out ahead. Some businesses get displaced by unpredictable circumstances and they go bankrupt. But on average, if a company is good at doing something and they pay out the earnings, you come out ahead. You get in trouble when businesses are good at something, and they take all the money they make and put it into doing something they are not good at. A business might only provide good cashflow for 10-20 years when the product is popular and before competitors cut into margins. If that money is squandered, the long term shareholder may ultimately have very terrible results. The long term shareholder ends up being the guy who keeps going all-in on a 80%-chance-to-win bet (that is what management is doing when they bet the company on the next unproven product), but eventually he gets zeroed out on one loss. This is why if you look at Buffett's investments, they are all in simple businesses that spits off cash to the owner/shareholder. Businesses like soft drinks, snacks, rail roads, vanilla banking, utility-like energy companies, insurance, etc. You might be good at judging the odds of whether a business will succeed or not (aka make more money than your original investment or not). But you don't want management of that company to make a wildly different bet for you. Just because they are great at operating a company doesn't mean they are good enough at judging odds or disciplined enough to make those bets for you. I may have predicted accurately that Business X will be a great success, but if manage takes those profits and goes all in on Business Y, without giving me a chance to cash out, that may have disasterous results.\"", "title": "" }, { "docid": "250018", "text": "\"not sure if I will help or just spread more gibberish but maybe the first concept I'd look at is risk tolerance.

As a practical matter, it's less likely to be exercised until expiry or shortly prior. The way to think about paying a European option is: [Odds of paying out] = [odds that strike is in the money at expiry] Whereas the American option can be thought of as: [Odds of paying out] = [odds that strike price is in the money at expiry] + ( [odds that strike price is in the money prior to expiry] * [odds that other party will exercise early] ). This is just a heuristic, not a formal financial tool. But the point is that you need to consider the odds that it will go into the money early, for how long (maybe over multiple periods), and how likely the counterparty is to exercise early. Important considerations for whether they will exercise early are the strategy of the other side (long, straddle, quick turnaround), the length of time the option is in the money early, and the anticipated future movement. A quick buck strategy might exercise immediately before the stock turns around. But that could leave further gains on the table, so it's usually best to wait unless the expectation is that the stock will quickly reverse its movement. This sort of counter-market strategy is generally unlikely from someone who bought the option at a certain strike, and is equivalent to betting against their original purchase of the option. So most of these people will wait because they expect the possibility of a bigger payoff. A long strategy is usually in no hurry to exercise, and in fact they would prefer to wait until the end to hold the time value of the option (the choice to get out of the option, if it goes back to being unprofitable). So it usually makes little sense for these people to exercise early. The same goes for a straddle, if someone is buying an option for insurance or to economically exit a position. So you're really just concerned that people will exercise early and forgo the time value of the American option. That may include people who really want to close a position, take their money, and move on. In some cases, it may include people who have become overextended or need liquidity, so they close positions. But for the most part, it's less likely to happen until the expiration approaches because it leaves potential value on the table. The time value of an option dwindles at the end because the implicit option becomes less likely, especially if the option is fairly deep in the money (the implicit option is then fairly deep out of the money). So early exercise becomes more meaningful concern as the expiration approaches.

If you would like to trade on the 2-6 month time scale you would need a signal that works on that sort of time scale.

An aside on technical analysis: michael's comment is generally correct though not well explained. Say Bob found a technical signal that works and he believes that a stock that costs $10 dollars should be $11. He buys it and makes money two months later when the rest of the market figures out the right price is $11 and he sells at that price. This works a bunch of times and he now publishes how the signal works on Stack Exchange to show everyone how awesome he is. Next time, Bob's signal finds a different stock at $10 that should be $11, but Anna just wrote a computer program that checks that signal Bob published faster than he ever could. The computer program buys as much as it can in milliseconds until the price is $11. Bob goes to buy, but now it is too late the price is already $11 and he can't make any money. Eventually, people learn to anticipate/adjust for this signal and even Anna's algorithms don't even work anymore and the hunt for new signals starts again.", "title": "" } ]

A short position essentially functions as follows: Here's the rub: you have unlimited loss potential. Maybe you borrow a share and sell it at $10. Maybe in a month you still haven't closed the position and now the share is trading at $1,000. The share lender comes calling for their share and you have to close the position at $1,000 for a loss of $990. Now what if it was $1,000,000 per share, etc. To avoid this unlimited loss risk, you can instead buy a put option contract. In this situation you buy a contract that will expire at some point in the future for the right to sell a share of stock for $x. You get to put that share on to someone else. If the underlying stock price were to instead rise above the put's exercise price, the put will expire worthless — but your loss is limited to the premium paid to acquire the put option contract.

The speculator's primary interest lies in anticipating and profiting from market fluctuations. The investor's primary interest lies in acquiring and holding suitable securities at suitable prices. Market movements are important to him in a practical sense, because they alternately create low price levels at which he would be wise to buy and high price levels at which he certainly should refrain from buying and probably would be wise to sell.

The stock itself can go up in price. This is not necessarily pure speculation either, the company could just reinvest the profits and grow. Since you own part of a company, your share would also increase in value. The company could also decide to start paying dividend. I think one rule of thumb is that growing companies won't pay out, since they reinvest all profit to grow even more, but very large companies like McDonalds or Microsoft who don't really have much room left to grow will pay dividends more. Surely the right to one vote for company A's Board can't be that valuable. Actually, Google for instance neither pays dividend nor do you get to vote. Basically all you get for your money is partial ownership of the company. This still gives you the right to seize Google assets if you go bankrupt, if there's any asset left once the creditors are done (credit gets priority over equity). What is it that I'm missing? What you are missing is that the entire concept of the dividend is an illusion. There's little qualitative difference between a stock that pays dividend, and a stock that doesn't. If you were going to buy the stock, then hold it forever and collect dividend, you could get the same thing with a dividend-less stock by simply waiting for it to gain say 5% value, then sell 4.76% of your stock and call the cash your dividend. \"\"But wait,\"\" you say, \"\"that's not the same - my net worth has decreased!\"\" Guess what, stocks that do pay dividend usually do drop in value right after the pay out, and they drop by about the relative value of the dividend as well. Likewise, you could take a stock that does pay dividend, and make it look exactly like a non-paying stock by simply taking every dividend you get and buying more of the same stock with it. So from this simplistic point of view, it is irrelevant whether the stock itself pays dividend or not. There is always the same decision of whether to cut the goose or let it lay a few more eggs that every shareholder has to make it. Paying a dividend is essentially providing a different default choice, but makes little difference with regards to your choices. There is however more to it than simple return on investment arithmetic: As I said, the alternative to paying dividend is reinvesting profits back into the enterprise. If the company decided to pay out dividend, that means they think all the best investing is done, and they don't really have a particularly good idea for what to do with the extra money. Conversely, not paying is like management telling the shareholders, \"\"no we're not done, we're still building our business!\"\". So it can be a way of judging whether the company is concentrating on generating profit or growing itself. Needless to say the, the market is wild and unpredictable and not everyone obeys such assumptions. Furthermore, as I said, you can effectively overrule the decision by increasing or decreasing your position, regardless of whether they have decided to pay dividend to begin with.

I found this interesting and thought I'd throw my 2c in. Good description (I hope) from Short Selling: What is Short Selling First, let's describe what short selling means when you purchase shares of stock. In purchasing stocks, you buy a piece of ownership in the company. You buy/sell stock to gain/sell ownership of a company. When an investor goes long on an investment, it means that he or she has bought a stock believing its price will rise in the future. Conversely, when an investor goes short, he or she is anticipating a decrease in share price. Short selling is the selling of a stock that the seller doesn't own. More specifically, a short sale is the sale of a security that isn't owned by the seller, but that is promised to be delivered. Still with us? Here's the skinny: when you short sell a stock, your broker will lend it to you. The stock will come from the brokerage's own inventory, from another one of the firm's customers, or from another brokerage firm. The shares are sold and the proceeds are credited to your account. Sooner or later, you must \"\"close\"\" the short by buying back the same number of shares (called covering) and returning them to your broker. If the price drops, you can buy back the stock at the lower price and make a profit on the difference. If the price of the stock rises, you have to buy it back at the higher price, and you lose money. So what happened? The Plan The Reality Lesson I never understood what \"\"Shorting a stock\"\" meant until today. Seems a bit risky for my blood, but I would assume this is an extreme example of what can go wrong. This guy literally chose the wrong time to short a stock that was, in all visible aspects, on the decline. How often does a Large Company or Individual buy stock on the decline... and send that stock soaring? How often does a stock go up 100% in 24 hours? 600%? Another example is recently when Oprah bought 10% of Weight Watchers and caused the stock to soar %105 in 24 hours.

Those numbers would make more sense. That being said, I can give you a simple example of how to calculate the profit and loss from a leveraged futures contract. For the sake of simplicity, I'll use a well-known futures contract: the E-mini S&P500 contract. Each E-mini is worth $50 times the value of the S&P 500 index and has a tick size of 0.25, so the minimum price change is 0.25 * $50 = $12.50. Here's an example. Say the current value of the S&P500 is 1,600; the value of each contract is therefore $50 * 1,600 = $80,000. You purchase one contract on margin, with an initial margin requirement1 of 5%, or $4,000. If the S&P 500 index rises to 1,610, the value of your futures contract increases to $50 * 1,610 = $80,500. Once you return the 80,000 - 4,000 = $76,000 that you borrowed as leverage, your profit is 80,500 - 76,000 = $4,500. Since you used $4,000 of your own funds as an initial margin, your profit, excluding commissions is 4,500 - 4,000 = $500, which is a 500/4000 = 12.5% return. If the index dropped to 1,580, the value of your futures contract decreases to $50 * 1,580 = $79,000. After you return the $76,000 in leverage, you're left with $3,000, or a net loss of (3,000 - 4000)/(4000) = -25%. The math illustrates why using leverage increases your risk, but also increases your potential for return. Consider the first scenario, in which the index increases to 1,610. If you had forgone using margin and spent $80,000 of your own funds, your profit would be (80,500 - 80,000) / 80000 = .625%. This is smaller than your leveraged profit by a factor of 20, the inverse of the margin requirement (.625% / .05 = 12.5%). In this case, the use of leverage dramatically increased your rate of return. However, in the case of a decrease, you spent $80,000, but gained $79,000, for a loss of only 1.25%. This is 20 times smaller in magnitude than your negative return when using leverage. By forgoing leverage, you've decreased your opportunity for upside, but also decreased your downside risk. 1) For futures contracts, the margin requirements are set by the exchange, which is CME group, in the case of the E-mini. The 5% in my example is higher than the actual margin requirement, which is currently $3,850 USD per contract, but it keeps the numbers simple.

You can also see a number of cases of IPOs of various types of companies that do not even have a revenue model at all. Also, if there is rapid sales growth in A but B sales are flat, no one is likely to expect future profit growth in B such that the valuation will remain steady.

Since the bulk of the intra-day trading was decided algorithmically, technical analysts had two main functions: This basically boils down to my answer to your question. There are still enough people, trading firms, etc. who believe in candlestick charting and other visually subjective patterns that if you notice a trend, pattern, etc. before the majority of traders observing, you may be able to time the market successfully and profit. This is becoming increasingly dangerous, however, because of the steps I outlined above. Over time, the charting patterns that have been proven effective (often in many firms individually since the algorithms are all proprietary) are incorporated into computer algorithms, so the \"\"traders\"\" you're competing with to see the pattern are increasingly low-latency computer clusters less than a few blocks from the exchange. Summary: Candlestick charting, along with other forms of subjective technical analysis, has its believers, and assuming enough of these believers trade the standard strategies based on the standard patterns, one could conceivably time the market with enough skill to anticipate these traders acting on the pattern and therefore profit. However, the marginal benefits of doing so are decreasing rapidly as computers take over more trading responsibility. Caveats: I know you're in Australia, where the market penetration of HF/algo traders isn't as high as in the US, so it might be a few more years before the marginal benefits cease to be profitable; that being said, if various forms of technical analysis proved wildly profitable in Australia, above and beyond profits available in other markets, rest assured that large American or British trading firms would already have moved in. My experience is limited to one trading firm, so I certainly can't speak for the industry as a whole. I know I didn't address candlestick charts specifically, but since they're only one piece of visual technical analysis, I tried to address the issue as a whole. This somewhat ties into the debate between fundamental or technical analysis, which I won't get into. Investopedia has a short article on the subject. As I said, I won't get into this because while it's a nice debate for small traders, at large trading firms, they don't care; they want to make profit, and any strategy that can be vetted, whether it's fundamental, technical, or astrological, will be vetted. I want to add more information to my answer to clear up some of the misconceptions in the comments, including those talking about biased studies and a lack of evidence for or against technical analysis (and candlestick charts; I'll explore this relationship further down). It's important to keep in mind that charting methods, including candlestick charts, are visually subjective ways of representing data, and that any interpretations drawn from such charts should, ideally, represent objective technical indicators. A charting method is only as good as the indicators it's used to represent. Therefore, an analysis of the underlying indicators provides a suitable analysis for the visual medium in which they're presented. One important study that evaluates several of these indicators is Foundations of Technical Analysis: Computational Algorithms, Statistical Inference, and Empirical Implementation by Lo, Mamaysky, and Wang. Lest anyone accuse its authors of bias, I should point out that not only is it published by the National Bureau of Economic Research (a highly reputable organization within economics and finance), but also that the majority of its authors come from MIT's Sloan school, which holds a reputation second to none. This study finds that several technical indicators, e.g. head-and-shoulder, double-bottom, and various rectangle techniques, do provide marginal value. They also find that although human judgment is still superior to most computational algorithms in the area of visual pattern recognition, ... technical analysis can be improved by using automated algorithms Since this paper was published in 2000, computing power and statistical analysis have gained significant ground against human ability to identify and exploit for visual pattern detection like candlestick charts. Second, I suggest you look into David Aaronson's book, Evidence-Based Technical Analysis: Applying the Scientific Method and Statistical Inference to Trading Signals. He finds similar results to the Lo, et. al. paper, in that some technical indicators do add value to the investment process, but those that do are those that can be represented mathematically and thus programmed directly into trading algorithms (thus bypassing visual tools like candlestick charts). He describes how studies, including Lo, et al., have found that head and shoulders patterns are worse than random, i.e. you would earn higher returns if you simply traded at random. That point is worth than repeating. If a day-trader is using a candlestick chart and using head-and-shoulders patterns as part of their toolkit, he's rolling the dice when he uses that pattern and returns that come from its application come from chance. This reminds me of that old story about a company that sends out pamphlets predicting the results of sports games, complete with \"\"strategies\"\" and \"\"data\"\" to back up the predictions. The company sends out several versions of the pamphlet every game, each predicting a different winner. Given a large enough sample size, by the end of the season, there are a few people who have received a pamphlet that accurately predicted the winner for every game and they're convinced the system is perfect. The others weren't so lucky, however. Relying on candlestick charts and TA patterns that are relics from the pre-computerized era is reassuring to some traders and gives them a sense of control and \"\"beating the market,\"\" but how long will chance remain on your side? This is why I maintain that visual tools like candlestick charts are a slowly dying medium. They certainly still add value to some trading firms, which is why Bloomberg terminals still ship with this functionality built in, but as more and more research shows, automated algorithms and statistical indicators can provide more value. It's also important to think about whether the majority of the value added by visual tools like candlestick charts comes in the form of profit or a sense of security to traders who learned the field using them over the past few decades. Finally, it's extremely important to realize that the actions of retail investors in the equities market cannot begin to represent the behaviors of the market as a whole. In the equities markets alone, trading firms and institutional investors dwarf retail investors, and the difference in scale is even more vastly pronounced in derivatives and currency markets. The fact that some retail investors use candlestick charts and the technical indicators they (hope) underlie them provides nothing but minor anecdotal evidence as to their effectiveness.\"", "title": "" }, { "docid": "181434", "text": "As I understand it, the correct price is any point between the minimum the seller is willing to accept and the maximum the buyer is willing to pay.

People don't want to pay a much higher price or accept a much lower price than they think the other party *should* agree to. For example, in the event of a sudden actual or anticipated shortage in some commodity consumer good, say... gasoline, it would make sense for sellers to raise the price significantly. In the short term, consumers of gasoline are very price-insensitive and most will pay more than double the usual price to obtain it.

Shareholders are taxed on dividends at the capital gains tax rate. A buyback returns the cash to shareholders who decide to sell. Other shareholders get a secondary benefit of now owning a slightly larger portion of the company since there are fewer shares outstanding. Shareholders only pay tax if they sell shares for a gain.

After expiration the option is worthless if it is out of the money but other than that has no hangover. Option prices normally drop as the time value of the option decays. An option has two values associated with it; time value and exercise value. Far out of the money (when the price of the underlying is far from the strike price on the losing side) options only have time value whereas deep in the money options (as yours seems to be) has some time value as well as the intrinsic value of the right to buy (sell) at a low (high) price and then sell (buy) the underlying. The time value of the option comes from the possibility that the price of the underlying will move (further) in your favour and make you more money at expiry. As expiry closes it is less likely that there will be a favourable mood so this value declines which can cause prices to move sharply after a period of little to no revaluing.

It appears to be based on the assumption that the price of a stock is equal to the value of the assets of a company divided by the total number of shares. But that simply isn't true. You don't even need to do any in-depth analysis to prove it. Just look at share prices over a few days. You should easily be able to find stocks whose price varied wildly. If, say, a company becomes the target of a federal investigation, the share price will plummet the day the announcement is made. Did the company's assets really disappear that day? No. What's happened is that the company's long term prospects are now in doubt. Or a company announces a promising new product. The share price shoots up. They may not have sold a single unit of the new product yet, they haven't made a dollar. But their future prospects now look improved. Many factors go into determining a stock price. Sure, total assets is a factor. But more important is anticipated future earning. I think a very simple case could be made that if a stock never paid any dividends, and if everyone knew it would never pay any dividends, that stock is worthless. The stock will never produce any profit to the owner. So why should you be willing to pay anything for it? One could say, The value could go up and you could sell at a profit. But on what basis would the value go up? Why would investors be willing to pay larger and larger amounts of money for an asset that produces zero income? Update I think I understand the source of the confusion now, so let me add to my answer. Suppose that a company's stock is selling for, say, $10. And to simplify the discussion let's suppose that there is absolutely nothing affecting the value of that stock except an expected dividend. The company plans to pay a dividend on a specific date of $1 per share. This dividend is announced well in advance. Everyone knows that it will be paid, and everyone is extremely confidant that in fact the company really will pay it -- they won't run out of money or any such. Then in a pure market, we would expect that as the date of that dividend approaches, the price of the stock would rise until the day before the dividend is paid, it is $11. Then the day after the dividend is paid the price would fall back to $10. Why? Because the person who owns the stock on the \"\"dividend day\"\" will get that $1. So if you bought the stock the day before the dividend, the next day you would immediately receive $1. If without the dividend the stock is worth $10, then the day before the dividend the stock is worth $11 because you know that the next day you will get a $1 \"\"refund\"\". If you buy the stock the day after the dividend is paid, you will not get the $1 -- it will go to the person who had the stock yesterday -- so the value of the stock falls back to the \"\"normal\"\" $10. So if you look at the value of a stock immediately after a dividend is paid, yes, it will be less than it was the day before by an amount equal to the dividend. (Plus or minus all the other things that affect the value of a stock, which in many cases would totally mask this effect.) But this does not mean that the dividend is worthless. Just the opposite. The reason the stock price fell was precisely because the dividend has value. BUT IT ONLY HAS VALUE TO THE PERSON WHO GETS IT. It does me no good that YOU get a $1 dividend. I want ME to get the money. So if I buy the stock after the dividend was paid, I missed my chance. So sure, in the very short term, a stock loses value after paying a dividend. But this does not mean that dividends in general reduce the value of a stock. Just the opposite. The price fell because it had gone up in anticipation of the dividend and is now returning to the \"\"normal\"\" level. Without the dividend, the price would never have gone up in the first place. Imagine you had a company with negligible assets. For example, an accounting firm that rents office space so it doesn't own a building, its only tangible assets are some office supplies and the like. So if the company liquidates, it would be worth pretty much zero. Everybody knows that if liquidated, the company would be worth zero. Further suppose that everyone somehow knows that this company will never, ever again pay a dividend. (Maybe federal regulators are shutting the company down because it's products were declared unacceptably hazardous, or the company was built around one genius who just died, etc.) What is the stock worth? Zero. It is an investment that you KNOW has a zero return. Why would anyone be willing to pay anything for it? It's no answer to say that you might buy the stock in the hope that the price of the stock will go up and you can sell at a profit even with no dividends. Why would anyone else pay anything for this stock? Well, unless their stock certificates are pretty and people like to collect them or something like that. Otherwise you're supposing that people would knowingly buy into a pyramid scheme. (Of course in real life there are usually uncertainties. If a company is dying, some people may believe, rightly or wrongly, that there is still hope of reviving it. Etc.) Don't confuse the value of the assets of a company with the value of its stock. They are related, of course -- all else being equal, a company with a billion dollars in assets will have a higher market capitalization than a company with ten dollars in assets. But you can't calculate the price of a company's stock by adding up the value of all its assets, subtracting liabilities, and dividing by the number of shares. That's just not how it works. Long term, the value of any stock is not the value of the assets but the net present value of the total future expected dividends.

However, if there is nothing else affecting the company's financials and investors perceive no other risks, it will probably bounce back a bit, but not back to the full value before the shares were issued. Why? Whenever a company issues more stock, the new shares dilute the value of the current shares outstanding, simply because there are now more shares of that stock trading on the market; the Earnings Per Share (EPS) Ratio will drop since the same profit and company value has to be spread across more shares. Example: If a company is valued at $100 dollars and they have 25 shares outstanding, then the EPS ratio equates to $4 per share (100/25 = 4). If the company then issues more shares (stock to employees who sell or keep them), let's say 25 more shares, then shares outstanding increase to 50, but the company's value still remains at $100 dollars. EPS now equates to $2 per share (100/50 = 2). Now, sometimes when shareholders (especially employees...and especially employees who just received them) suddenly all sell their shares, this causes a micro-panic in the market because investors believe the employees know something bad about the company that they don't. Other common shareholders then want to dump their holdings for fear of impending collapse in the company. This could cause the share price to dip a bit below the new diluted value, but again if no real, immediate risks exist, the price should go back up to the new, diluted value. Example 2: If EPS was at $4 before issuing more stock, and then dropped to $2 after issuing new stock, the micro-panic may cause the EPS to drop below $2 and then soon rebound back to $2 or more when investors realize no actual risk exists. After the dilution phase plays out, the EPS could actually even go above the pre-issuing value of $4 because investors may believe that since more stock was issued due to good profits, more profits may ensue.

If I am short 100 shares of MSFT, that means that my broker let me borrow 100 shares of MSFT, and I chose to sell them. While I am short 100 shares of MSFT, I owe 100 shares of MSFT to my broker whenever he demands them back. Until he demands them back, I owe interest on the value of those 100 shares. You short a stock when you feel it is about to drop in price. The idea there is that if MSFT is at $50 and I short it, I borrow 100 shares from my broker and sell for $5000. If MSFT falls to $48 the next day, I buy back the 100 shares and give them back to my broker. I pocket the difference ($50 - $48 = $2/share x 100 shares = $200), minus interest owed. Call and Put options. People manage the risk of owning a stock or speculate on the future move of a stock by buying and selling calls and puts. Call and Put options have 3 important components. The stock symbol they are actionable against (MSFT in this case), the \"\"strike price\"\" - $52 in this case, and an expiration, June. If you buy a MSFT June $52 Call, you are buying the right to purchase MSFT stock before June options expiration (3rd Saturday of the month). They are priced per share (let's say this one cost $0.10/share), and sold in 100 share blocks called a \"\"contract\"\". If you buy 1 MSFT June $52 call in this scenario, it would cost you 100 shares x $0.10/share = $10. If you own this call and the stock spikes to $56 before June, you may exercise your right to purchase this stock (for $52), then immediately sell the stock (at the current price of $56) for a profit of $4 / share ($400 in this case), minus commissions. This is an overly simplified view of this transaction, as this rarely happens, but I have explained it so you understand the value of the option. Typically the exercise of the option is not used, but the option is sold to another party for an equivalent value. You can also sell a Call. Let's say you own 100 shares of MSFT and you would like to make an extra $0.10 a share because you DON'T think the stock price will be up to $52/share by the end of June. So you go to your online brokerage and sell one contract, and receive the $0.10 premium per share, being $10. If the end of June comes and nobody exercises the option you sold, you get to keep the $10 as pure profit (minus commission)! If they do exercise their option, your broker makes you sell your 100 shares of MSFT to that party for the $52 price. If the stock shot up to $56, you don't get to gain from that price move, as you have already committed to selling it to somebody at the $52 price. Again, this exercise scenario is overly simplified, but you should understand the process. A Put is the opposite of a Call. If you own 100 shares of MSFT, and you fear a fall in price, you may buy a PUT with a strike price at your threshold of pain. You might buy a $48 June MSFT Put because you fear the stock falling before June. If the stock does fall below the $48, you are guaranteed that somebody will buy yours at $48, limiting your loss. You will have paid a premium for this right (maybe $0.52/share for example). If the stock never gets down to $48 at the end of June, your option to sell is then worthless, as who would sell their stock at $48 when the market will pay you more? Owning a Put can be treated like owning insurance on the stock from a loss in stock price. Alternatively, if you think there is no way possible it will get down to $48 before the end of June, you may SELL a $48 MSFT June Put. HOWEVER, if the stock does dip down below $48, somebody will exercise their option and force you to buy their stock for $48. Imagine a scenario that MSFT drops to $30 on some drastically terrible news. While everybody else may buy the stock at $30, you are obligated to buy shares for $48. Not good! When you sold the option, somebody paid you a premium for buying that right from you. Often times you will always keep this premium. Sometimes though, you will have to buy a stock at a steep price compared to market. Now options strategies are combinations of buying and selling calls and puts on the same stock. Example -- I could buy a $52 MSFT June Call, and sell a $55 MSFT June Call. I would pay money for the $52 Call that I am long, and receive money for the $55 Call that I am short. The money I receive from the short $55 Call helps offset the cost of buying the $52 Call. If the stock were to go up, I would enjoy the profit within in $52-$55 range, essentially, maxing out my profit at $3/share - what the long/short call spread cost me. There are dozens of strategies of mixing and matching long and short calls and puts depending on what you expect the stock to do, and what you want to profit or protect yourself from. A derivative is any financial device that is derived from some other factor. Options are one of the most simple types of derivatives. The value of the option is derived from the real stock price. Bingo? That's a derivative. Lotto? That is also a derivative. Power companies buy weather derivatives to hedge their energy requirements. There are people selling derivatives based on the number of sunny days in Omaha. Remember those calls and puts on stock prices? There are people that sell calls and puts based on the number of sunny days in Omaha. Sounds kind of ridiculous -- but now imagine that you are a solar power company that gets \"\"free\"\" electricity from the sun and they sell that to their customers. On cloudy days, the solar power company is still on the hook to provide energy to their customers, but they must buy it from a more expensive source. If they own the \"\"Sunny Days in Omaha\"\" derivative, they can make money for every cloudy day over the annual average, thus, hedging their obligation for providing more expensive electricity on cloudy days. For that derivative to work, somebody in the derivative market puts a price on what he believes the odds are of too many cloudy days happening, and somebody who wants to protect his interests from an over abundance of cloudy days purchases this derivative. The energy company buying this derivative has a known cost for the cost of the derivative and works this into their business model. Knowing that they will be compensated for any excessive cloudy days allows them to stabilize their pricing and reduce their risk. The person selling the derivative profits if the number of sunny days is higher than average. The people selling these types of derivatives study the weather in order to make their offers appropriately. This particular example is a fictitious one (I don't believe there is a derivative called \"\"Sunny days in Omaha\"\"), but the concept is real, and the derivatives are based on anything from sunny days, to BLS unemployment statistics, to the apartment vacancy rate of NYC, to the cost of a gallon of milk in Maine. For every situation, somebody is looking to protect themselves from something, and somebody else believes they can profit from it. Now these examples are highly simplified, many derivatives are highly technical, comprised of multiple indicators as a part of its risk profile, and extremely difficult to explain.

I will just like to add on to what everyone has said here and will like to explain how various interest rates you mentioned work out when the risk free rate moves: For brevity, let's denote the risk free rate by Rf, the savings account interest rate as Rs, a mortgage interest rate as Rmort, and a term deposit rate with the bank as Rterm. Savings account interest rate: When a central bank revises the overnight lending rate (or the prime rate, repo rate etc.), in some countries banks are not obliged to increase the savings account interest rate. Usually a downward revision will force them to lower it (because they net they will be paying out = Rf - Rs). On the other hand, if Rf goes up and if one of the banks increases the Rs then other banks may be forced to do so too under competitive pressure. In some countries the central bank has the authority to revise Rs without revising the overnight lending rate. Term deposits with the bank (or certificates of deposit): Usually movements in these rates are more in sync with Rf than Rs is. The chief difference is that savings account offer more liquidity than term deposits and hence banks can offer lower rates and still get deposits under them --consider the higher interest rate offered by the term deposit as a liquidity risk premium. Generally, interest rates paid by instruments of similar risk profile that offer similar liquidity will move in parallel (otherwise there can be arbitrage). Sometimes these rates can move to anticipate a future change in Rf. Mortgage loan rates or other interests that you pay to the bank: If the risk free rate goes up, banks will increase these rates to keep the net interest they earn over risk free (= Δr = Rmort - Rf) the same. If Rf drops and if banks are not obliged to decrease loan rates then they will only do so if one of the banks does it first. P.S:- Wherever I have said they will do so when one of the banks does it first, I am not referring to a recursion but merely to the competitive market theory. Under such a theory, the first one to cut down the profit margin usually has a strong business incentive to do so (e.g., gain market share, or eliminate competition by lowering profit margins etc.).

However, when nuts were added to an existing diet without controlling for energy intake, body weight increased, although to a lesser extent than theoretically predicted. There is limited evidence on the effect nut consumption has on type 2 diabetes, although available evidence indicates that nuts as part of a healthy diet do not cause weight gain and can have a positive influence on the fatty acid profile of a person with diabetes.

Numerous epidemiological and clinical studies show that nuts are not associated with weight gain.

Compensatory dietary responses account for 55-75% of the energy provided by nuts. Limited data suggest that routine nut consumption is associated with elevated resting energy expenditure and the thermogenic effect of feeding, resulting in dissipation of another portion of the energy they provide.

Results Subjects in all three groups were matched at baseline for BMI: DCG 28.03 ± 4.3; RSG 28.12 ± 3.22; and HSG 28.01 ± 4.51 kg/m2. There were no significant changes in body weight or BMI in any groups during the study nor any change from baseline at any time point in any group. During the entire study, there were no significant differences in waist-to-hip ratio among the groups or any change from baseline in any group (DCG -0.00 ± 0.03, RSG -0.01 ± 0.02 and HSG 0.01 ± 0.04). There were no significant differences detected among groups in triglycerides, fasting glucose and 2 hour postprandial glucose following a 75 gram glucose challenge. Exploratory analyses demonstrated that glucose values 2 h after a 75 gm glucose challenge were significantly lower at week 12 compared with baseline values in the HSG group (-1.13 ± 2.58 mmol/L, p = 0.02), and a similar trend was noted in the RSG group (-0.77 ± 2.07 mmol/L, p = 0.06), while no significant change was seen in the DCG group (-0.15 ± 2.27 mmol/L, p = 0.530). At the end of study, serum triglyceride levels were significantly lower compared with baseline in the RSG group (-0.38 ± 0.79 mmol/L, p = 0.018), but no significant changes were observed in the HSG or DCG groups. Conclusion Despite concerns that pistachio nut consumption may promote weight gain, the daily ingestion of either 42 g or 70 g of pistachios for 12 weeks did not lead to weight gain or an increase in waist-to-hip ratio in Chinese subjects with metabolic syndrome.

We aimed to investigate effect of the Antep pistachio (Pistacia vera L.) on blood glucose, lipid parameters, endothelial function, inflammation, and oxidation in healthy young men living in a controlled environment. METHODS: A Mediterranean diet was administered to normolipidemic 32 healthy young men (mean age 22 y, range 21-24) for 4 wk. After 4 wk, participants continued to receive the Mediterranean diet but pistachio was added for 4 wk by replacing the monounsaturated fat content constituting approximately 20% of daily caloric intake. Fasting blood samples and brachial endothelial function measurements were performed at baseline and after each diet. RESULTS: Compared with the Mediterranean diet, the pistachio diet decreased glucose (P<0.001, -8.8+/-8.5%), low-density lipoprotein (P<0.001, -23.2+/-11.9%), total cholesterol (P<0.001, -21.2+/-9.9%), and triacylglycerol (P=0.008, -13.8+/-33.8%) significantly and high-density lipoprotein (P=0.069, -3.1+/-11.7%) non-significantly. Total cholesterol/high-density lipoprotein and low-density lipoprotein/high-density lipoprotein ratios decreased significantly (P<0.001 for both). The pistachio diet significantly improved endothelium-dependent vasodilation (P=0.002, 30% relative increase), decreased serum interleukin-6, total oxidant status, lipid hydroperoxide, and malondialdehyde and increased superoxide dismutase (P<0.001 for all), whereas there was no significant change in C-reactive protein and tumor necrosis factor-alpha levels. CONCLUSION: In this trial, we demonstrated that a pistachio diet improved blood glucose level, endothelial function, and some indices of inflammation and oxidative status in healthy young men. These findings are in accordance with the idea that nuts, in particular pistachio nuts, have favorable effects beyond lipid lowering that deserve to be evaluated with prospective follow-up studies.

It is valued for its distinct biting quality attributed to the alkaloid, piperine. Black pepper is used not only in human dietaries but also for a variety of other purposes such as medicinal, as a preservative, and in perfumery. Many physiological effects of black pepper, its extracts, or its major active principle, piperine, have been reported in recent decades. Dietary piperine, by favorably stimulating the digestive enzymes of pancreas, enhances the digestive capacity and significantly reduces the gastrointestinal food transit time. Piperine has been demonstrated in in vitro studies to protect against oxidative damage by inhibiting or quenching free radicals and reactive oxygen species. Black pepper or piperine treatment has also been evidenced to lower lipid peroxidation in vivo and beneficially influence cellular thiol status, antioxidant molecules and antioxidant enzymes in a number of experimental situations of oxidative stress. The most far-reaching attribute of piperine has been its inhibitory influence on enzymatic drug biotransforming reactions in the liver. It strongly inhibits hepatic and intestinal aryl hydrocarbon hydroxylase and UDP-glucuronyl transferase. Piperine has been documented to enhance the bioavailability of a number of therapeutic drugs as well as phytochemicals by this very property. Piperine's bioavailability enhancing property is also partly attributed to increased absorption as a result of its effect on the ultrastructure of intestinal brush border. Although initially there were a few controversial reports regarding its safety as a food additive, such evidence has been questionable, and later studies have established the safety of black pepper or its active principle, piperine, in several animal studies.

However, there is little information on the effects of hazelnut consumption on cardiovascular risk markers. METHODS: The antiatherogenic effect of hazelnut before and after consumption in hypercholesterolemic subjects was investigated. Twenty-one hypercholesterolemic volunteers (18 men and 3 women) were recruited in a double control sandwich model intervention study with a single group and three isoenergetic diet periods. These were control diet I (4 weeks), hazelnut-enriched diet (4 weeks; hazelnut contributing 18%-20% of the total daily energy intake), and control diet period II (4 weeks). The cardiovascular risk biomarkers such as endothelial function, using flow-mediated dilation (FMD) technique, low-density lipoprotein (LDL) oxidation products and inflammatory markers such as high-sensitivity C-reactive protein (hs-CRP), soluble intercellular adhesion molecule-1, and soluble vascular cell adhesion molecule-1 (sVCAM-1) as well as lipids and lipoprotein levels were monitored. RESULTS: Consumption of a hazelnut-enriched diet significantly improved FMD (56.6%), total cholesterol (-7.8%), triacylglycerol (-7.3%), LDL-cholesterol (-6.17%), and high-density lipoprotein cholesterol (6.07%) compared with the control diet I. Oxidized-LDL, hs-CRP, and sVCAM-1 levels were significantly lower in the group ingesting a hazelnut-enriched diet compared with the control diets I and II. Modest correlations between sVCAM-1 and FMD and between sVCAM-1 and hs-CRP were observed (r = -0.49, P < .025; r = 0.66, P < .001, respectively). CONCLUSION: Hazelnut-enriched diets may exert antiatherogenic effect by improving endothelial function, preventing LDL oxidation, and inflammatory markers, in addition to their lipid and lipoprotein-lowering effects. These beneficial effects appeared to be reversible after 4 weeks on a hazelnut-free diet. Therefore, hazelnut may be incorporated into daily diet without change in total caloric intake for sustained health benefit. Copyright © 2013 National Lipid Association.

Design Experimental, “proof of principle” study in which six dogs were trained to discriminate between urine from patients with bladder cancer and urine from diseased and healthy controls and then evaluated in tests requiring the selection of one bladder cancer urine sample from six controls. Participants 36 male and female patients (age range 48-90 years) presenting with new or recurrent transitional cell carcinoma of the bladder (27 samples used for training; 9 used for formal testing); 108 male and female controls (diseased and healthy, age range 18-85 years—54 samples used in training; 54 used for testing). Main outcome measure Mean proportion of successes per dog achieved during evaluation, compared with an expected value of 1 in 7 (14%). Results Taken as a group, the dogs correctly selected urine from patients with bladder cancer on 22 out of 54 occasions. This gave a mean success rate of 41% (95% confidence intervals 23% to 58% under assumptions of normality, 26% to 52% using bootstrap methods), compared with 14% expected by chance alone. Multivariate analysis suggested that the dogs' capacity to recognise a characteristic bladder cancer odour was independent of other chemical aspects of the urine detectable by urinalysis.

The provision of antibiotics to food animals encompasses a wide variety of nontherapeutic purposes that include growth promotion. The concern over resistance emergence and spread to people by nontherapeutic use of antimicrobials has led to conflicted practices and opinions. Considerable evidence supported the removal of nontherapeutic antimicrobials (NTAs) in Europe, based on the “precautionary principle.” Still, concrete scientific evidence of the favorable versus unfavorable consequences of NTAs is not clear to all stakeholders. Substantial data show elevated antibiotic resistance in bacteria associated with animals fed NTAs and their food products. This resistance spreads to other animals and humans—directly by contact and indirectly via the food chain, water, air, and manured and sludge-fertilized soils. Modern genetic techniques are making advances in deciphering the ecological impact of NTAs, but modeling efforts are thwarted by deficits in key knowledge of microbial and antibiotic loads at each stage of the transmission chain.

Why do sole proprietors in India generally use a current account?
[ { "docid": "456636", "text": "Current account offers a lot of benefits for sole proprietors. Think of it like bank account for a company. The bank provides a host of facilities for the company. A sole proprietor does not have enough value as that of a company for a bank but needs similar services. Thus Indian banks offer a toned down version of the account offered to a company. Current account offer very good overdraft ( withdrawing money even if balance is zero). This feature is very useful as business cycles and payment schedules can be different for each supplier/customer the sole proprietor does business with. Imagine the sole proprietor account has balance of zero on day 0. customer X made payment by cheque on day 1. Cheques will get credited only on Day 3 (Assume Day 2 is a national holiday or weekend). Sole proprietor gave a cheque to his supplier on day 0. The supplier deposited the cheque on Day 0 and the sole proprietor's bank will debit the the proprietor's account on day 1. As customer's cheque will get credited only day 3, the overdraft facility will let the proprietor borrow from the bank Interestingly, current accounts were offered long before Indian banks started offering customized accounts to corporate customers.

Also, you're generally required to separate corporate and personal funds to keep the limited liability protection (which is why you have the corporation to begin with). Generally, business accounts have much higher volumes and much more transactions than personal accounts, and it costs more for the banks to run them. In the US, some banks offer free, or very low-cost, business accounts for small businesses that don't need too many transactions.

Do not use your EIN in place of your social security number (SSN). As you say your EIN is for your business as a sole proprietor, I would also refer to Publication 334, Tax Guide for Small Business, under \"\"Identification Numbers\"\": Social security number (SSN). Generally, use your SSN as your taxpayer identification number. You must put this number on each of your individual income tax forms, such as Form 1040 and its schedules. Employer identification number (EIN). You must also have an EIN to use as a taxpayer identification number if you do either of the following. Pay wages to one or more employees. File pension or excise tax returns. If you must have an EIN, include it along with your SSN on your Schedule C or C-EZ as instructed. While I can't point to anything specifically about bank accounts, in general the guidance I see is that your SSN is used for your personal stuff, and you have an EIN for use in your business where needed. You may be able to open a bank account listing the EIN as the taxpayer identification number on the account. I don't believe there's a legal distinction between what makes something a \"\"business\"\" account or not, though a bank may have different account offerings for different purposes, and only offer some of them to entities rather than individuals. If you want to have a separate account for your business transactions, you may want them to open it in the name of your business and they may allow you to use your EIN on it. Whether you can do this for one of their \"\"personal\"\" account offerings would be up to the bank. I don't see any particular advantages to using your EIN on a bank account for an individual, though, and I could see it causing a bit of confusion with the bank if you're trying to do so in a way that isn't one of their \"\"normal\"\" account types for a business. As a sole proprietor, there really isn't any distinction between you and your business. Any interest income is taxable to you in the same way. But I don't think there's anything stopping you legally other than perhaps your particular bank's policy on such things.

Update for clarification: other countries do have similar concepts, but I'm not aware of any country that uses the term LLC, nor any other country that uses the single-member LLC that is disregarded for income tax purposes that I'm referring to here (and that I assume the recruiter also was talking about). Further, LLCs vary by state. I only have experience with California, so some things may not apply the same way elsewhere. Also, if you are located in one state but the client is elsewhere, things can get more complex. First, let's get one thing out of the way: do you want to be a contractor, or an employee? Both have advantage, and especially in the higher-income areas, contractor can be more beneficial for you. Make sure that if you are a contractor, your rate must be considerably higher than as employee, to make up for the benefits you give up, as well as the FICA taxes and your expense of maintaining an LLC (in California, it costs at least $800/year, plus legal advice, accounting, and various other fees etc.). On the other hand, oftentimes, the benefits as an employee aren't actually worth all that much when you are in high income brackets. Do pay attention to health insurance - that may be a valuable benefit, or it may have such high deductibles that you would be better off getting your own or paying the penalty for going uninsured. Instead of a 401(k), you can set up an IRA (update or various other options), and you can also replace all the other benefits. If you decide that being an employee is the way to go, stop here. If you decide that being a contractor is a better deal for you, then it is indeed a good idea to set up an LLC. You actually have three fundamental options: work as an individual (the legal term is \"\"sole proprietorship\"\"), form a single-member LLC disregarded for income tax purposes, or various other forms of incorporation. Of these, I would argue that the single-member LLC combines the best of both worlds: taxation is almost the same as for sole proprietorship, the paperwork is minimal (a lot less than any other form of incorporation), but it provides many of the main benefits of incorporating. There are several advantages. First, as others have already pointed out, the IRS and Department of Labor scrutinize contractor relationships carefully, because of companies that abused this status on a massive scale (Uber and now-defunct Homejoy, for instance, but also FedEx and other old-economy companies). One of the 20 criteria they use is whether you are incorporated or not. Basically, it adds to your legal credibility as a contractor. Another benefit is legal protection. If your client (or somebody else) sues \"\"you\"\", they can usually only sue the legal entity they are doing business with. Which is the LLC. Your personal assets are safe from judgments. That's why Donald Trump is still a billionaire despite his famous four bankruptcies (which I believe were corporate, not personal, bankrupcies). Update for clarification Some people argue that you are still liable for your personal actions. You should consult with a lawyer about the details, but most business liabilities don't arise from such acts. Another commenter suggested an E&O policy - a very good idea, but not a substitute for an LLC. An LLC does require some minimal paperwork - you need to set up a separate bank account, and you will need a professional accounting system (not an Excel spreadsheet). But if you are a single member LLC, the paperwork is really not a huge deal - you don't need to file a separate federal tax return. Your income will be treated as if it was personal income (the technical term is that the LLC is disregarded for IRS tax purposes). California still does require a separate tax return, but that's only two pages or so, and unless you make a large amount, the tax is always $800. That small amount of paperwork is probably why your recruiter recommended the LLC, rather than other forms of incorporation. So if you want to be a contractor, then it sounds like your recruiter gave you good advice. If you want to be an employee, don't do it. A couple more points, not directly related to the question, but hopefully generally helpful: If you are a contractor (whether as sole proprietor or through an LLC), in most cities you need a business license. Not only that, but you may even need a separate business license in every city you do business (for instance, in the city where your client is located, even if you don't live there). Business licenses can range from \"\"not needed\"\" to a few dollars to a few hundred dollars. In some cities, the business license fee may also depend on your income. And finally, one interesting drawback of a disregarded LLC vs. sole proprietorship as a contractor has to do with the W-9 form and your Social Security Number. Generally, when you work for somebody and receive more than $600/year, they need to ask you for your Social Security Number, using form W-9. That is always a bit of a concern because of identity theft. The IRS also recognizes a second number, the EIN (Employer Identification Number). This is basically like an SSN for corporations. You can also apply for one if you are a sole proprietor. This is a HUGE benefit because you can use the EIN in place of your SSN on the W-9. Instant identity theft protection. HOWEVER, if you have a disregarded LLC, the IRS says that you MUST use your SSN; you cannot use your EIN!

If there is a chance this will happen, then stop, make it so that it won't happen. The big danger is in being able to have traceability between what you are doing for the business, and what you are doing for yourself. If you are using this as a \"\"staging\"\" account for investments, etc., are those investments for yourself? Or for the business? Is tax treatment on capital gains and/or dividends the same for personal and business in your jurisdiction? If you buy a widget, is the widget an expense against business income? Or is it an out of pocket expense for personal consumption? The former reduces your taxable income, the latter does not. I don't see the benefit of a real business account because those have features specific to maybe corporations, LLC, and etc. -- nothing beneficial to a sole proprietor who has no reports/employees. The real benefit is that there is a clear delineation between business income/expenses and personal income/expenses. This account can also accept money and hold it from business transactions/sales, and possibly transfer some to the personal account if there's no need for reinvesting said amount/percentage. What you are looking for is a commonly called a current account, because it is used for current expenses.

I, in fact, just incorporated. You will be able \"\"save\"\" more in taxes in the end. The reason I put \"\"save\"\" in quotes, is that you don't necessarily save on taxes, but you can defer taxes. The driving factor behind this is that you specify your own fiscal calendar/year. Incorporating allows you to defer income for up to 6 months. Meaning that if you make your fiscal year starting in August or September, for example, you can claim that income on the following year (August + 6 months = February). It allows you to keep the current year taxes down. Also, any income left over at year end, is taxed at 15% (the Corporation rate) rather than the 30-40% personal rate you get with a sole-proprietorship. In a nutshell, with sole-proprietorship, all income is taxable (after write-offs)... in a corporation, you can take some of that income and keep it in the corporation (gives your company a \"\"value\"\"), and is only taxed at 15% - big saving there.

It is good advice to keep all personal and business financial matters separate. This makes it easier to prove to the IRS that all your business expenses are actually business related. In this case however, the two items [tax payment for personal income vs tax payment for business income] are inseparable. What you can do, however, for your own personal records, is calculate how much of your tax payment relates to your business. I wouldn't get complicated about this; I would simply take the net income of your business as a % of your taxable income, and multiply that against your tax payment. ie: if your business net income is $10,000, and your total taxable income is $50,000, and you paid $6,000 in taxes, I would record that 20% of the $6k was related to business income. If you have a separate bank account for your sole proprietorship, you could make a transfer to your personal account of $1,200, and then make the $6k payment from your personal account. Remember that tax payments for either your sole proprietorship and your personal income will be treated the same: federal tax payments are not tax deductible, and state tax payments are tax deductible, whether they were paid for your sole proprietorship or the rest of your personal income. So even though this method is simplistic [for example, it doesn't factor in that different investment income types earned personally will have a lower rate than your sole proprietorship income], any difference wouldn't have an impact on any future tax liability.

What kind of taxes are we looking into paying into the business (besides setup of everything) compared to being a self proprietor? (I'm seeing that the general answer is no, as long as income is <200k, but not certain). Unless you decide to have your LLC taxed as a corporation, there's no change in taxes. LLC, by default, is a pass-through entity and all income will flow to your respective tax returns. From tax perspective, the LLC will be treated as a partnership. It will file form 1065 to report its income, and allocate the income to the members/partners on schedules K-1 which will be given to you. You'll use the numbers on the K-1 to transfer income allocated to you to your tax returns and pay taxes on that.

Your contract counterparts couldn't care less about your tax problems. Unless you are a corporation, people who pay you more than $600 a year must file a 1099. Since you'll be a partnership, you'll need to provide the partnership EIN instead of your own SSN, but that's the only difference. Are LLC's required to pay taxes 4 times per year? We would definitely get an accountant for things, but being as this is side work, there will be times where we choose to not take on clients, which could cause multiple months of no income. Obviously we would save for when we need to pay taxes, but is there a magic number that says \"\"you must now pay four times per year\"\". Unless you choose to tax your LLC as a corporation, LLC will pay no taxes. You will need to make sure you have enough withholding to cover for the additional income, or pay the quarterly estimates. The magic number is $1000. If your withholding+estimates is $1000 less than what your tax liability is, you'll be penalized, unless the total withholding+estimates is more than 100% of your prior year tax liability (or 110%, depending on the amounts). The LLC would be 50% 50%, but that work would not always be that. We will be taking on smaller project through the company, so there will be times where one of us could potentially be making more money. Are we setting ourselves up for disaster if one is payed more than the other while still having equal ownership?

So what you are referring to is in Finance something called Funds Transfer Pricing or FTP (often referred to as just Transfer Pricing). Like anything else, FTP has its place. Most companies; however, don't use it properly. FTP, theoretically, has one primary purpose (although it's developed a second): to properly allocate opportunity costs across divisions. Let's say Company A produces widgets. They sell these widgets for $200 at a TOTAL COST of $150 and book profits of $50. Now to produce the widget Division 1 makes a computer chip at a cost of $50 that it then \"\"sells\"\" to Division 2 for $60. Division 1 then books a profit of $10. Division 2 then makes some plastic stuff and assembles the device. This is labor intensive so Division 2's costs are $100. Company A sells the completed device for $150. Division 2 subsequently books profits of $40, and appears much more profitable than Division 1, on the surface. The problem arises when Division 1 could sell the chip to the open market for $125. Now it costs them $50 to produce, and they could make a theoretical profit of $75. This is MORE than the company makes AS A WHOLE on the entire device. By having Division 2 pay effectively \"\"fair market price\"\" for that chip, you realize that Division 2 is really operating at a loss (the *opportunity cost* of not selling the chip to market is greater than producing the completed device). Company A would be better off getting rid of Division 2 and solely focusing on Division 1. In a good FTP system, Division 2 would pay the fair market price of $125. If done properly, management would hopefully realize it should divest Division 2. That's the ***fundamental premise*** behind FTP. In actuality things get much more complicated because of economics, the company itself, branding, IT, operations, management, PPE, labor laws, etc. Thats why most companies screw it up. All that other stuff falls under whats called cost allocation accounting. It gets VERY complex and entire masters courses are dedicated to it (different methods, etc.) The other thing you can do with FTP is get crazy tax breaks due to various tax laws. The simplified explanation is that divisions pay taxes on profits to the government ***that division*** is located in (this works on the state level, too btw.). GE does a lot of this and it's a big part of why they pay almost no-taxes. Again, it gets more complicated when you involve audits as there's some grey area legally. For simplicity, assume tax rates are 40% in the US and 10% in India. So let's say GE makes an airplane engine in the US but \"\"finishes\"\" manufacturing in India. These specific engines costs $5,000,000 for the US division to make, up to a certain point. The US division can then sell the engine at a break even to India. So India \"\"pays\"\" $5,000,000 for the engine. The US division then books no profit. India finishes the manufacturing with additional costs of $1,000,000. The India division then sells the engine to the open market for $9,000,000 . Therefore, the India division books a profit of $3,000,000 and pays taxes of $300,000. Now GE as a whole makes a profit of $3,000,000 less taxes of $300,000 = net profit of $2,700,00. Further, let's say the fair market value of the engine, as is, when the US sells to India is $7,000,000. That would mean US ***should*** book profits of $2,000,000 and India ***should*** book profits of $1,000,000. Total taxes by GE are now $800,000 (US) + $100,000 (India) = $900,000. However, what's important is that NET PROFIT is now $2,100,000. ***GE just saved $600,000 in taxes by doing this***. The beauty of this is, divisions are supposed to charge fair market value for products FTP'd internationally; however, it's REALLY hard for the IRS to say what the value of an unfinished product really is (heck, you could be offering bulk discounts, etc.)... The fact is, often, US divisions have skilled labor that is difficult to replicate elsewhere. They just show US divisions operating at losses to make the company as a whole better. The problem, again, arises when top management don't fully appreciate or understand the reasoning behind this stuff. They end up making cuts to US labor because it's \"\"unprofitable\"\" without thinking about the entire story. I know this is very long winded but hope it helps! ***tldr; companies FTP to recognizes profitability and opportunity costs of divisions as well as use it for overseas tax breaks.*** Side note: Politically speaking, people who know how this works are pissed off about it in the U.S. (don't worry though, most politicians on both sides don't have a clue). We have high corporate tax rates relative to other countries and IRS loopholes allow this kind of thing (lobbying $$). It's also why, economically, you can't just raise ***corporate*** tax rates to increase domestic tax reciepts as more companies will just implement this process (it's complicated to do properly). Also, please don't say 50 years ago tax rates were higher and raising taxes increased receipts. The fact is most companies couldn't even FATHOM doing this 50 years ago, no less even 20. edit: some clarification in wording\"", "title": "" }, { "docid": "133235", "text": "\"Do I understand correctly, that we still can file as \"\"Married filing jointly\"\", just add Schedule C and Schedule SE for her?

It is generally easier to run as sole trader versus a Limited Company, ie less paperwork and beaureaucracy. If you go down the Limited Company route, the company would be liable to pay Corporation Tax on any profits and this process is more complicated and you would probably need an accountant to do that for you, which is likely to cost a few hundred pounds every year. You can do it yourself but the process is not as simple as doing your own income tax return. Also as a sole trader you can do what you like with any income, you can spend it and treat it as your own wages. You can't do that if you set up a Limited Company as the income is \"\"owned\"\" by the company and so you would need to in effect pay yourself a wage from the company.

While the latter observation explains a long-standing observation that plasmid transformation is very inefficient in S. pneumoniae (compared to chromosomal transformation), the former supports our previous suggestion that SsbB creates a reservoir of ssDNA, allowing successive recombination cycles. SsbBΔ7 fulfils the reservoir function, suggesting that SsbB C-ter is not necessary for processing protein(s) to access stored ssDNA.

CNBP has been found to bind single-stranded nucleic acid and promote rearrangements of nucleic acid secondary structure in an ATP-independent manner, acting as a nucleic acid chaperone. METHODS A variety of methods were used, including cell viability assays, wound-scratch assays, chemotaxis assays, invasion assays, circular dichroic (CD) spectroscopy, NMR spectroscopy, chromatin immunoprecipitation, expression and purification of recombinant human CNBP, electrophoretic mobility shift assay (EMSA), surface plasmon resonance (SPR), fluorescence resonance energy transfer (FRET) analyses, luciferase reporter assay, Western blotting, and isothermal titration calorimetry (ITC).

In contrast, recent evidence suggests that GAL in the paraventricular nucleus (PVN) functions in close relation to dietary fat and alcohol. In particular, it mediates functions that allow animals to adapt to conditions of positive energy balance involving excess consumption of these nutrients. This peptide in the PVN is stimulated by a high-fat diet and also by alcohol. It is stimulated by an increase in circulating lipids caused by a fat-rich meal or alcohol consumption, and it rises during the middle of the active feeding cycle, when fat consumption and triglycerides naturally rise. When centrally injected, GAL in the PVN increases the consumption of food and alcohol. Moreover, it produces a significantly stronger feeding response in rats maintained on a fat-rich diet, which also promotes alcohol intake. This evidence supports the existence of non-homeostatic, positive feedback circuits between GAL and both dietary fat and alcohol. These circuits are believed to contribute to the large meal size, over-consumption of alcohol, and obesity which are generally associated with fat-rich foods.", "title": "Regulation and effects of hypothalamic galanin: relation to dietary fat, alcohol ingestion, circulating lipids and energy homeostasis." }, { "docid": "188911", "text": "Antigen-presenting, major histocompatibility complex (MHC) class II-rich dendritic cells are known to arise from bone marrow. However, marrow lacks mature dendritic cells, and substantial numbers of proliferating less-mature cells have yet to be identified. The methodology for inducing dendritic cell growth that was recently described for mouse blood now has been modified to MHC class II-negative precursors in marrow. A key step is to remove the majority of nonadherent, newly formed granulocytes by gentle washes during the first 2-4 d of culture. This leaves behind proliferating clusters that are loosely attached to a more firmly adherent \"stroma. \" At days 4-6 the clusters can be dislodged, isolated by 1-g sedimentation, and upon reculture, large numbers of dendritic cells are released. The latter are readily identified on the basis of their distinct cell shape, ultrastructure, and repertoire of antigens, as detected with a panel of monoclonal antibodies. The dendritic cells express high levels of MHC class II products and act as powerful accessory cells for initiating the mixed leukocyte reaction. Neither the clusters nor mature dendritic cells are generated if macrophage colony-stimulating factor rather than granulocyte/macrophage colony-stimulating factor (GM-CSF) is applied. Therefore, GM-CSF generates all three lineages of myeloid cells (granulocytes, macrophages, and dendritic cells).

DATA SYNTHESIS Results summarised as relative risks for dichotomous data and mean differences for continuous data. RESULTS We identified 44 relevant randomised controlled trials (7278 women) evaluating three categories of interventions: diet, physical activity, and a mixed approach. Overall, there was 1.42 kg reduction (95% confidence interval 0.95 to 1.89 kg) in gestational weight gain with any intervention compared with control. With all interventions combined, there were no significant differences in birth weight (mean difference -50 g, -100 to 0 g) and the incidence of large for gestational age (relative risk 0.85, 0.66 to 1.09) or small for gestational age (1.00, 0.78 to 1.28) babies between the groups, though by itself physical activity was associated with reduced birth weight (mean difference -60 g, -120 to -10 g). Interventions were associated with a reduced the risk of pre-eclampsia (0.74, 0.60 to 0.92) and shoulder dystocia (0.39, 0.22 to 0.70), with no significant effect on other critically important outcomes. Dietary intervention resulted in the largest reduction in maternal gestational weight gain (3.84 kg, 2.45 to 5.22 kg), with improved pregnancy outcomes compared with other interventions. The overall evidence rating was low to very low for important outcomes such as pre-eclampsia, gestational diabetes, gestational hypertension, and preterm delivery.

You may be happy with the asset allocation, or this tool may inform you to adjust your portfolio to meet your long-term goals. The next step will be to choose a benchmark.

Depending on the region and stock characteristics you are investing in, you may want to pick a more specialized index, such as the ones listed here in this WSJ list.

There are several downsides to this strategy: You aren't taking into account commissions. If you pay $5 each time you buy or sell a stock, you may greatly reduce or even eliminate any possible gains you would make from trading such small amounts. This next point sounds obvious, but remember that you pay a commission on every trade regardless of profit, so every trade you make that you make at a loss also costs you commissions. Even if you make trades that are profitable more often than not, if you make quite a few trades with small amounts like this, your commissions may eat away all of your profits. Commissions represent a fixed cost, so their effect on your gains decreases proportionally with the amount of money you place at risk in each trade. Since you're in the US, you're required to follow the SEC rules on pattern day trading. From that link, \"\"FINRA rules define a “pattern day trader” as any customer who executes four or more “day trades” within five business days, provided that the number of day trades represents more than six percent of the customer’s total trades in the margin account for that same five business day period.\"\" If you trip this rule, you'll be required to maintain $25,000 in a margin brokerage account. If you can't maintain the balance, your account will be locked. Don't forget about capital gains taxes. Since you're holding these securities for less than a year, your gains will be taxed at your ordinary income tax rates. You can deduct your capital losses too (assuming you don't repurchase the same security within 30 days, because in that case, the wash sale rule prevents you from deducting the loss), but it's important to think about gains and losses in real terms, not nominal terms. The story is different if you make these trades in a tax-sheltered account like an IRA, but the other problems still apply. You're implicitly assuming that the stock's prices are skewed in the positive direction. Remember that you have limit orders placed at the upper and lower bounds of the range, so if the stock price decreases before it increases, your limit order at the lower bound will be triggered and you'll trade at a loss. If you're hoping to make a profit through buying low and selling high, you want a stock that hits its upper bound before hitting the lower bound the majority of the time. Unless you have data analysis (not just your intuition or a pattern you've talked yourself into from looking at a chart) to back this up, you're essentially gambling that more often than not, the stock price will increase before it decreases. It's dangerous to use any strategy that you haven't backtested extensively. Find several months or years of historical data, either intra-day or daily data, depending on the time frame you're using to trade, and simulate your strategy exactly. This helps you determine the potential profitability of your strategy, and it also forces you to decide on a plan for precisely when you want to invest. Do you invest as soon as the stock trades in a range (which algorithms can determine far better than intuition)? It also helps you figure out how to manage your risk and how much loss you're willing to accept. For risk management, using limit orders is a start, but see my point above about positively skewed prices. Limit orders aren't enough. In general, if an active investment strategy seems like a \"\"no-brainer\"\" or too good to be true, it's probably not viable. In general, as a retail investor, it's foolish to assume that no one else has thought of your simple active strategy to make easy money. I can promise you that someone has thought of it. Trading firms have quantitative researchers that are paid to think of and implement trading strategies all the time. If it's viable at any scale, they'll probably already have utilized it and arbitraged away the potential for small traders to make significant gains. Trust me, you're not the first person who thought of using limit orders to make \"\"easy money\"\" off volatile stocks. The fact that you're asking here and doing research before implementing this strategy, however, means that you're on the right track. It's always wise to research a strategy extensively before deploying it in the wild. To answer the question in your title, since it could be interpreted a little differently than the body of the question: No, there's nothing wrong with investing in volatile stocks, indexes, etc. I certainly do, and I'm sure many others on this site do as well. It's not the investing that gets you into trouble and costs you a lot of money; it's the rapid buying and selling and attempting to time the market that proves costly, which is what you're doing when you implicitly bet that the distribution of the stock's prices is positively skewed. To address the commission fee problem, assuming a fee of $8 per trade ... and a minimum of $100 profit per sale Commissions aren't your only problem, and counting on $100 profit per sale is a significant assumption. Look at point #4 above. Through your use of limit orders, you're making the implicit assumption that, more often than not, the price will trigger your upper limit order before your lower limit order. Here's a simple example; let's assume you have limit orders placed at +2 and -2 of your purchase price, and that triggering the limit order at +2 earns you $100 profit, while triggering the limit order at -2 incurs a loss of $100. Assume your commission is $5 on each trade. If your upper limit order is triggered, you earn a profit of 100 - 10 = 90, then set up the same set of limit orders again. If your lower limit order is triggered this time, you incur a loss of 100 + 10 = 110, so your net gain is 90 - 110 = -20. This is a perfect example of why, when taking into account transaction costs, even strategies that at first glance seem profitable mathematically can actually fail. If you set up the same situation again and incur a loss again (100 + 10 = 110), you're now down -20 - 110 = -130. To make a profit, you need to make two profitable trades, without incurring further losses. This is why point #4 is so important. Whenever you trade, it's critical to completely understand the risk you're taking and the bet you're actually making, not just the bet you think you're making. Also, according to my \"\"algorithm\"\" a sale only takes place once the stock rises by 1 or 2 points; otherwise the stock is held until it does. Does this mean you've removed the lower limit order? If yes, then you expose yourself to downside risk. What if the stock has traded within a range, then suddenly starts declining because of bad earnings reports or systemic risks (to name a few)? If you haven't removed the lower limit order, then point #4 still stands. However, I never specified that the trades have to be done within the same day. Let the investor open up 5 brokerage accounts at 5 different firms (for safeguarding against being labeled a \"\"Pattern Day Trader\"\"). Each account may only hold 1 security at any time, for the span of 1 business week. How do you control how long the security is held? You're using limit orders, which will be triggered when the stock price hits a certain level, regardless of when that happens. Maybe that will happen within a week, or maybe it will happen within the same day. Once again, the bet you're actually making is different from the bet you think you're making. Can you provide some algorithms or methods that do work for generating some extra cash on the side, aside from purchasing S&P 500 type index funds and waiting? When I purchase index funds, it's not to generate extra liquid cash on the side. I don't invest nearly enough to be able to purchase an index fund and earn substantial dividends. I don't want to get into any specific strategies because I'm not in the business of making investment recommendations, and I don't want to start. Furthermore, I don't think explicit investment recommendations are welcome here (unless it's describing why something is a bad idea), and I agree with that policy. I will make a couple of points, however. Understand your goals. Are you investing for retirement or a shorter horizon, e.g. some side income? You seem to know this already, but I include it for future readers. If a strategy seems too good to be true, it probably is. Educate yourself before designing a strategy. Research fundamental analysis, different types of orders (e.g., so you fully understand that you don't have control over when limit orders are executed), different sectors of the market if that's where your interests lie, etc. Personally, I find some sectors fascinating, so researching them thoroughly allows me to make informed investment decisions as well as learn about something that interests me. Understand your limits. How much money are you willing to risk and possibly lose? Do you have a risk management strategy in place to prevent unexpected losses? What are the costs of the risk management itself? Backtest, backtest, backtest. Ideally your backtesting and simulating should be identical to actual market conditions and incorporate all transaction costs and a wide range of historical data. Get other opinions. Evaluate those opinions with the same critical eye as I and others have evaluated your proposed strategy.\"", "title": "" }, { "docid": "188497", "text": "The idea of an index is that it is representative of the market (or a specific market segment) as a whole, so it will move as the market does.

By far the most important aspect when choosing index funds is the ongoing cost, usually expressed as Total Expense Ratio (TER), which tells you how much of your investment will be eaten up by trading fees and to pay the funds' operating costs (and profits).

Are there flat trading fees? Is there a minimum investment? What lot sizes are possible? Can you set up a monthly payment plan? Can you automatically reinvest dividends/coupons? Then of course you have to decide which index, i.e. which market you want to buy into. My answer in the other question apparently didn't make it clear, but I was talking only about stock indices.

Among those, it makes some sense to just choose your home country's main index, because that eliminates currency risk and is also often cheaper. Alternatively, you might want to use the opportunity to diversify internationally so that if your country's economy tanks, you won't lose your job and see your investment take a dive. Finally, you should of course choose a well-established, reputable issuer. But this isn't really a business for startups (neither shady nor disruptively consumer-friendly) anyway.", "title": "" }, { "docid": "477646", "text": "\"Diversification is spreading your investments around so that one point of risk doesn't sink your whole portfolio. The effect of having a diversified portfolio is that you've always got something that's going up (though, the corollary is that you've also always got something going down... winning overall comes by picking investments worth investing in (not to state the obvious or anything :-) )) It's worth looking at the different types of risk you can mitigate with diversification: Company risk This is the risk that the company you bought actually sucks. For instance, you thought gold was going to go up, and so you bought a gold miner. Say there are only two -- ABC and XYZ. You buy XYZ. Then the CEO reveals their gold mine is played out, and the stock goes splat. You're wiped out. But gold does go up, and ABC does gangbusters, especially now they've got no competition. If you'd bought both XYZ and ABC, you would have diversified your company risk, and you would have been much better off. Say you invested $10K, $5K in each. XYZ goes to zero, and you lose that $5K. ABC goes up 120%, and is now worth $11K. So despite XYZ bankrupting, you're up 10% on your overall position. Sector risk You can categorize stocks by what \"\"sector\"\" they're in. We've already talked about one: gold miners. But there are many more, like utilities, bio-tech, transportation, banks, etc. Stocks in a sector will tend to move together, so you can be right about the company, but if the sector is out of favor, it's going to have a hard time going up. Lets extend the above example. What if you were wrong about gold going up? Then XYZ would still be bankrupt, and ABC would be making less money so they went down as well; say, 20%. At that point, you've only got $4K left. But say that besides gold, you also thought that banks were cheap. So, you split your investment between the gold miners and a couple of banks -- lets call them LMN and OP -- for $2500 each in XYZ, ABC, LMN, and OP. Say you were wrong about gold, but right about banks; LMN goes up 15%, and OP goes up 40%. At that point, your portfolio looks like this: XYZ start $2500 -100% end $0 ABC start $2500 +120% end $5500 LMN start $2500 +15% end $2875 OP start $2500 +40% end $3500 For a portfolio total of: $11,875, or a total gain of 18.75%. See how that works? Region/Country/Currency risk So, now what if everything's been going up in the USA, and everything seems so overpriced? Well, odds are, some area of the world is not over-bought. Like Brazil or England. So, you can buy some Brazilian or English companies, and diversify away from the USA. That way, if the market tanks here, those foreign companies aren't caught in it, and could still go up. This is the same idea as the sector risk, except it's location based, instead of business type based. There is an additional twist to this -- currencies. The Brits use the pound, and the Brazilians use the real. Most small investors don't think about this much, but the value of currencies, including our dollar, fluctuates. If the dollar has been strong, and the pound weak (as it has been, lately), then what happens if that changes? Say you own a British bank, and the dollar weakens and the pound strengthens. Even if that bank doesn't move at all, you would still make a gain. Example: You buy British bank BBB for 40 pounds a share, when each pound costs $1.20. Say after a while, BBB is still 40 pounds/share, but the dollar weakened and the pound strengthened, such that each pound is now worth $1.50. You could sell BBB, and because of the currency exchange once you've got it converted back to dollars you'd have a 25% gain. Market cap risk Sometimes big companies do well, sometimes it's small companies. The small caps are riskier but higher returning. When you think about it, small and mid cap stocks have much more \"\"room to run\"\" than large caps do. It's much easier to double a company worth $1 billion than it is to double a company worth $100 billion. Investment types Stocks aren't the only thing you can invest in. There's also bonds, convertible bonds, CDs, preferred stocks, options and futures. It can get pretty complicated, especially the last two. But each of these investment behaves differently; and again the idea is to have something going up all the time. The classical mix is stocks and bonds. The idea here is that when times are good, the stocks go up; when times are bad, the bonds go up (because they're safer, so more people want them), but mostly they're there to providing steady income and help keep your portfolio from cratering along with the stocks. Currently, this may not work out so well; stocks and bonds have been moving in sync for several years, and with interest rates so low they don't provide much income. So what does this mean to you? I'm going make some assumptions here based on your post. You said single index, self-managed, and don't lower overall risk (and return). I'm going to assume you're a small investor, young, you invest in ETFs, and the single index is the S&P 500 index ETF -- SPY. S&P 500 is, roughly, the 500 biggest companies in the USA. Further, it's weighted -- how much of each stock is in the index -- such that the bigger the company is, the bigger a percentage of the index it is. If slickcharts is right, the top 5 companies combined are already 11% of the index! (Apple, Microsoft, Exxon, Amazon, and Johnson & Johnson). The smallest, News Corp, is a measly 0.008% of the index. In other words, if all you're invested in is SPY, you're invested in a handfull of giant american companies, and a little bit of other stuff besides. To diversify: Company risk and sector risk aren't really relevant to you, since you want broad market ETFs; they've already got that covered. The first thing I would do is add some smaller companies -- get some ETFs for mid cap, and small cap value (not small cap growth; it sucks for structural reasons). Examples are IWR for mid-cap and VBR for small-cap value. After you've done that, and are comfortable with what you have, it may be time to branch out internationally. You can get ETFs for regions (such as the EU - check out IEV), or countries (like Japan - see EWJ). But you'd probably want to start with one that's \"\"all major countries that aren't the USA\"\" - check out EFA. In any case, don't go too crazy with it. As index investing goes, the S&P 500 is not a bad way to go. Feed in anything else a little bit at a time, and take the time to really understand what it is you're investing in. So for example, using the ETFs I mentioned, add in 10% each IWR and VBR. Then after you're comfortable, maybe add 10% EFA, and raise IWR to 20%. What the ultimate percentages are, of course, is something you have to decide for yourself. Or, you could just chuck it all and buy a single Target Date Retirement fund from, say, Vanguard or T.

I just want to place it somewhere and let it grow Your intuition is spot on! To buy & hold is the sensible thing to do. There is no need to constantly monitor the stock market. To invest successfully you only need some basic pointers. People make it look like it's more complicated than it actually is for individual investors. You might find useful some wisdom pearls I wish I had learned even earlier. Stocks & Bonds are the best passive investment available. Stocks offer the best return, while bonds are reduce risk. The stock/bond allocation depends of your risk tolerance. Since you're as young as it gets, I would forget about bonds until later and go with a full stock portfolio. Banks are glorified money mausoleums; the interest you can get from them is rarely noticeable. Index investing is the best alternative. How so? Because 'you can't beat the market'. Nobody can; but people like to try and fail. So instead of trying, some fund managers simply track a market index (always successfully) while others try to beat it (consistently failing). Actively managed mutual funds have higher costs for the extra work involved. Avoid them like the plague. Look for a diversified index fund with low TER (Total Expense Ratio). These are the most important factors. Diversification will increase safety, while low costs guarantee that you get the most out of your money. Vanguard has truly good index funds, as well as Blackrock (iShares). Since you can't simply buy equity by yourself, you need a broker to buy and sell. Luckily, there are many good online brokers in Europe. What we're looking for in a broker is safety (run background checks, ask other wise individual investors that have taken time out of their schedules to read the small print) and that charges us with low fees. You probably can do this through the bank, but... well, it defeats its own purpose. US citizens have their 401(k) accounts. Very neat stuff. Check your country's law to see if you can make use of something similar to reduce the tax cost of investing. Your government will want a slice of those juicy dividends. An alternative is to buy an index fund on which dividends are not distributed, but are automatically reinvested instead.

There is no other way, if you have money, you need to know how to deal with it, or you are likely to lose it all.

Are they? Maybe not all the time! If you had invested in an index fund tracking the S&P500 at the start of 2000 you would still be behind in terms of capital appreciation when taking inflation into considerations. Your only returns in 13.5 years would have been any dividends you may have received. See the monthly chart of the S&P500 below. Diversification can be good for your overall returns, but diversification simply for diversification sake is as you said, a way of reducing your overall returns in order of smoothing out your equity curve. After looking up indexes for various countries the only one that had made decent returns over a 13.5 year period was the Indian BSE 30 index, almost 400% over 13.5 years, although it also has gone nowhere since the end of 2007 (5.5 years). See monthly chart below. So investing internationally (especially in developing countries when developed nations are stagnating) can improve your returns, but I would learn about the various international markets first before plunging straight in. Regarding investing in an Index fund vs direct investment in a select group of shares, I did a search on the US markets with the following criteria on the 3rd January 2000: If the resulting top 10 from the search were bought on 3rd January 2000 and held up until the close of the market on the 19th June 2013, the results would be as per the table below: The result, almost 250% return in 13.5 years compared to almost no return if you had invested into the whole S&P 500 Index. Note, this table lists only the top ten from the search without screening through the charts, and no risk management was applied (if risk management was applied the 4 losses of 40%+ would have been limited to a maximum of 20%, but possibly much smaller losses or even for gains, as they might have gone into positive territory before coming back down - as I have not looked at any of the charts I cannot confirm this).

If you don't, you will probably lose money in the long term due to inflation (how's that for a risk? :). There are plenty of options for the risk averse, many of which handily beat inflation, though without knowing your country of residence, it's hard to say. In all likelihood, though, you'll want to invest in index funds -- such as ETFs -- that basically track industries, rather than individual companies. This is basically free portfolio diversity -- they lose money only when an entire sector loses value. Though even with funds of this type, you still want to ensure you purchase multiple different funds that track different industries. Don't just toss all of your funds into an IT index, for example. Before buying, just look at the history of the fund and make sure it has had a general upward trajectory since 2008 (I've bought a few ETFs that remained static...not what we're looking for in an investment!). If the brokerage account you choose doesn't offer commission free trades on any of the funds you want (personally, I use Schwab and their ETF portfolio), try to \"\"buy in bulk.\"\" That way you're not spending so much on trades. There are other considerations (many indexed funds have high management costs, but if you go with ETFs, they don't, and there's the question of dividends, etc), but that is getting into the weeds as far as investing knowledge is concerned.

So, here's the overview. Despite the presence of asset allocation calculators and what not, this is a subjective matter. Only you know how much risk you are willing to take. You seem to be aware of one rule of thumb, namely that with a longer investing horizon you can stand to take on more risk. However, how much risk you should take is subject to your own risk aversion. Honestly, the best way to answer your questions is to educate yourself about the individual topics. There are just too many variables to provide neat, concise answers to such a broad question. There are no easy ways around this. You should not blindly rely on the opinions of others, but rather use your own judgment to asses their advice. Some of the links I provide in the main text: S&P 500: Total and Inflation-Adjusted Historical Returns 10-year index fund returns The Motley Fool Risk aversion Disclaimer: These are the opinions of an enthusiastic amateur. Why should I invest 20% in domestic large cap and 10% in developing markets instead of 10% in domestic large cap and 20% in developing markets? Should I invest in REITs? Why or why not? Simply put, developing markets are very risky. Even if you have a long investment horizon, you should pace yourself and not take on too much risk. How much is \"\"too much\"\" is ultimately subjective. Specific to why 10% in developing vs 20% in large cap, it is probably because 10% seems like a reasonable amount of your total portfolio to gamble. Another way to look at this is to consider that 10% as gone, because it is invested in very risky markets. So, if you're willing to take a 20% haircut, then by all means do that. However, realize that you may be throwing 1/5 of your money out the window. Meanwhile, REITs can be quite risky as investing in the real estate market itself can be quite risky. One reason is that the assets are very much fixed in place and thus can not be liquidated in the same way as other assets. Thus, you are subject to the vicissitudes of a relatively small market. Another issue is the large capital outlays required for most commercial building projects, thus typically requiring quite a bit of credit and risk. Another way to put it: Donald Trump made his name in real estate, but it was (and still is) a very bumpy ride. Yet another way to put it: you have to build it before they will come and there is no guarantee that they will like what you built. What mutual funds or index funds should I investigate to implement these strategies? I would generally avoid actively managed mutual funds, due to the expenses. They can seriously eat into the returns. There is a reason that the most mutual funds compare themselves to the Lipper average instead of something like the S&P 500. All of those costs involved in managing a mutual fund (teams of people and trading costs) tend to weigh down on them quite heavily. As the Motley Fool expounded on years ago, if you can not do better than the S&P 500, you should save yourself the headaches and simply invest in an S&P 500 index fund. That said, depending on your skill (and luck) picking stocks (or even funds), you may very well have been able to beat the S&P 500 over the past 10 years. Of course, you may have also done a whole lot worse. This article discusses the performance of the S&P 500 over the past 60 years. As you can see, the past 10 years have been a very bumpy ride yielding in a negative return. Again, keep in mind that you could have done much worse with other investments. That site, Simple Stock Investing may be a good place to start educating yourself. I am not familiar with the site, so do not take this as an endorsement. A quick once-over of the material on the site leads me to believe that it may provide a good bit of information in readily digestible forms. The Motley Fool was a favorite site of mine in the past for the individual investor. However, they seem to have turned to the dark side, charging for much of their advice. That said, it may still be a good place to get started. You may also decide that it is worth paying for their advice. This blog post, though dated, compares some Vanguard index funds and is a light introduction into the contrarian view of investing. Simply put, this view holds that one should not be a lemming following the crowd, rather one should do the opposite of what everyone else is doing. One strong argument in favor of this view is the fact that as more people pile onto an investing strategy or into a particular market, the yields thin out and the risk of a correction (i.e. a downturn) increases. In the worst case, this leads to a bubble, which corrects itself suddenly (or \"\"pops\"\" thus the term \"\"bubble\"\") leading to quite a bit of pain for the unprepared participants. An unprepared participant is one who is not hedged properly. Basically, this means they were not invested in other markets/strategies that would increase in yield as a result of the event that caused the bubble to pop. Note that the recent housing bubble and resulting credit crunch beat quite heavily on the both the stock and bond markets. So, the easy hedge for stocks being bonds did not necessarily work out so well. This makes sense, as the housing bubble burst due to concerns over easy credit. Unfortunately, I don't have any good resources on hand that may provide starting points or discuss the various investing strategies. I must admit that I am turning my interests back to investing after a hiatus. As I stated, I used to really like the Motley Fool, but now I am somewhat suspicious of them. The main reason is the fact that as they were exploring alternatives to advertising driven revenue for their site, they promised to always have free resources available for those unwilling to pay for their advice. A cursory review of their site does show a decent amount of general investing information, so take these words with a grain of salt. (Another reason I am suspicious of them is the fact that they \"\"spammed\"\" me with lots of enticements to pay for their advice which seemed just like the type of advice they spoke against.) Anyway, time to put the soapbox away. As I do that though, I should explain the reason for this soapboxing. Simply put, investing is a risky endeavor, any way you slice it. You can never eliminate risk, you can only hope to reduce it to an acceptable level. What is acceptable is subject to your situation and to the magnitude of your risk aversion. Ultimately, it is rather subjective and you should not blindly follow someone else's opinion (professional or otherwise). Point being, use your judgment to evaluate anything you read about investing. If it sounds too good to be true, it probably is. If someone purports to have some strategy for guaranteed (steady) returns, be very suspicious of it. (Read up on the Bernard Madoff scandal.) If someone is putting on a heavy sales pitch, be weary. Be especially suspicious of anyone asking you to pay for their advice before giving you any solid understanding of their strategy. Sure, many people want to get paid for their advice in some way (in fact, I am getting \"\"paid\"\" with reputation on this site). However, if they take the sketchy approach of a slimy salesmen, they are likely making more money from selling their strategy, than they are from the advice itself. Most likely, if they were getting outsized returns from their strategy they would keep quiet about it and continue using it themselves. As stated before, the more people pile onto a strategy, the smaller the returns. The typical model for selling is to make money from the sale. When the item being sold is an intangible good, your risk as a buyer increases. You may wonder why I have written at length without much discussion of asset allocation. One reason is that I am still a relative neophyte and have a mostly high level understanding of the various strategies. While I feel confident enough in my understanding for my own purposes, I do not necessarily feel confident creating an asset allocation strategy for someone else. The more important reason is that this is a subjective matter with a lot of variables to consider. If you want a quick and simple answer, I am afraid you will be disappointed. The best approach is to educate yourself and make these decisions for yourself. Hence, my attempt to educate you as best as I can at this point in time. Personally, I suggest you do what I did. Start reading the Wall Street Journal every day. (An acceptable substitute may be the business section of the New York Times.) At first you will be overwhelmed with information, but in the long run it will pay off. Another good piece of advice is to be patient and not rush into investing. If you are in a hurry to determine how you should invest in a 401(k) or other such investment vehicle due to a desire to take advantage of an employer's matching funds, then I would place my money in an S&P 500 index fund. I would also explore placing some of that money into broad index funds from other regions of the globe. The reason for broad index funds is to provide some protection from the normal fluctuations and to reduce the risk of a sudden downturn causing you a lot pain while you determine the best approach for yourself. In this scenario, think more about capital preservation and hedging against inflation then about \"\"beating\"\" the market.\"", "title": "" }, { "docid": "259145", "text": "\"Is evaluating stocks just a loss of time if the stock is traded very much?

Not exactly. Indexes give the best long term performance when compared to actively managing investments directly in the underlying stocks. That is, if you compare an S&P500 index to trying to pick stocks that are part of it, you're more likely to succeed with blindly following the index than trying to actively beat it. That said, no-one promises that investing in S&P500 is better than investing in DJIA, for example. These are two different indexes tracking different stocks and areas. So when advisers say \"\"diversify\"\" they don't mean it that you should diversify between different stocks that build up the S&P500 index. They mean that you should diversify your investments in different areas. Some in S&P500, some in DJIA, some in international indexes, some in bond indexes, etc. Still, investing in various indexes will likely yield better results than actively managing the investments trying to beat those indexes, but you should not invest in only one, and that is the meaning of diversification. In the comments you asked \"\"why diversify at all?\"\", and that is entirely a different question from your original \"\"what diversification is?\"\". You diversify to reduce the risk of loss from one side, and widen the net for gains from another. The thing is that any single investment can eventually fail, regardless of how it performed before. You can see that the S&P500 index lost 50% of its value twice within ten years, whereas before it was doubling itself every several years. Many people who were only invested in that index (or what's underlying to it) lost a lot of money. But consider you've diversified, and in the last 20 years you've invested in a blend of indexes that include the S&P500, but also other investments like S&P BSE SENSEX mentioned by Victor below. You would reduce your risk of loss on the American market by increasing your gains on the Indian market. Add to the mix soaring Chinese Real Estate market during the time of the collapse of the US real-estate, gains on the dollar losing its value by investing in other currencies (Canadian dollar, for example), etc. There are many risks, and by diversifying you mitigate them, and also have a chance to create other potential gains. Now, another question is why invest in indexes. That has been answered before on this site. It is my opinion that some methods of investing are just gambling by trying to catch the wave and they will almost always fail, and rarely will individual stock picking beat the market.

The first is the historical record: In the past, and in many countries, stock market investors have been rewarded with such a premium. ... Historically, bond returns have lagged equity returns by about 5–6 percentage points, annualized—amounting to an enormous return differential in most circumstances over longer time periods. Consequently, retirement savers investing only in “safe” assets must dramatically increase their savings rates to compensate for the lower expected returns those investments offer. ... The second strategic principle underlying our glidepath construction—that younger investors are better able to withstand risk—recognizes that an individual’s total net worth consists of both their current financial holdings and their future work earnings. For younger individuals, the majority of their ultimate retirement wealth is in the form of what they will earn in the future, or their “human capital.” Therefore, a large commitment to stocks in a younger person’s portfolio may be appropriate to balance and diversify risk exposure to work-related earnings (To the question of how the exact allocations were decided:) As part of the process of evaluating and identifying an appropriate glide path given this theoretical framework, we ran various financial simulations using the Vanguard Capital Markets Model.

Your adviser has a good point; as long as you intend to enjoy your retirement in your home country then it might be advisable to remove currency risk by holding an account in Rupees. However, you might like to consider reducing the other forms of risk by holding non-Indian securities to create a globally diversified portfolio, and also placing some of your capital in an account with a broker outside your home country (this may be very difficult to do in practice).", "title": "" }, { "docid": "476517", "text": "Your idea is a good one, but, as usual, the devil is in the details, and implementation might not be as easy as you think. The comments on the question have pointed out your Steps 2 and 4 are not necessarily the best way of doing things, and that perhaps keeping the principal amount invested in the same fund instead of taking it all out and re-investing it in a similar, but different, fund might be better. The other points for you to consider are as follows. How do you identify which of the thousands of conventional mutual funds and ETFs is the average-risk / high-gain mutual fund into which you will place your initial investment? Broadly speaking, most actively managed mutual fund with average risk are likely to give you less-than-average gains over long periods of time. The unfortunate truth, to which many pay only Lipper service, is that X% of actively managed mutual funds in a specific category failed to beat the average gain of all funds in that category, or the corresponding index, e.g. S&P 500 Index for large-stock mutual funds, over the past N years, where X is generally between 70 and 100, and N is 5, 10, 15 etc. Indeed, one of the arguments in favor of investing in a very low-cost index fund is that you are effectively guaranteed the average gain (or loss :-(, don't forget the possibility of loss). This, of course, is also the argument used against investing in index funds. Why invest in boring index funds and settle for average gains (at essentially no risk of not getting the average performance: average performance is close to guaranteed) when you can get much more out of your investments by investing in a fund that is among the (100-X)% funds that had better than average returns? The difficulty is that which funds are X-rated and which non-X-rated (i.e. rated G = good or PG = pretty good), is known only in hindsight whereas what you need is foresight. As everyone will tell you, past performance does not guarantee future results. As someone (John Bogle?) said, when you invest in a mutual fund, you are in the position of a rower in rowboat: you can see where you have been but not where you are going. In summary, implementation of your strategy needs a good crystal ball to look into the future. There is no such things as a guaranteed bond fund. They also have risks though not necessarily the same as in a stock mutual fund. You need to have a Plan B in mind in case your chosen mutual fund takes a longer time than expected to return the 10% gain that you want to use to trigger profit-taking and investment of the gain into a low-risk bond fund, and also maybe a Plan C in case the vagaries of the market cause your chosen mutual fund to have negative return for some time. What is the exit strategy?", "title": "" }, { "docid": "113786", "text": "\"There are two umbrellas in investing: active management and passive management. Passive management is based on the idea \"\"you can't beat the market.\"\" Passive investors believe in the efficient markets hypothesis: \"\"the market interprets all information about an asset, so price is equal to underlying value\"\". Another idea in this field is that there's a minimum risk associated with any given return. You can't increase your expected return without assuming more risk. To see it graphically: As expected return goes up, so does risk. If we stat with a portfolio of 100 bonds, then remove 30 bonds and add 30 stocks, we'll have a portfolio that's 70% bonds/30% stocks. Turns out that this makes expected return increase and lower risk because of diversification. Markowitz showed that you could reduce the overall portfolio risk by adding a riskier, but uncorrelated, asset! Basically, if your entire portfolio is US stocks, then you'll lose money whenever US stocks fall. But, if you have half US stocks, quarter US bonds, and quarter European stocks, then even if the US market tanks, half your portfolio will be unaffected (theoretically). Adding different types of uncorrelated assets can reduce risk and increase returns. Let's tie this all together. We should get a variety of stocks to reduce our risk, and we can't beat the market by security selection. Ideally, we ought to buy nearly every stock in the market so that So what's our solution? Why, the exchange traded fund (ETF) of course! An ETF is basically a bunch of stocks that trade as a single ticker symbol. For example, consider the SPDR S&P 500 (SPY). You can purchase a unit of \"\"SPY\"\" and it will move up/down proportional to the S&P 500. This gives us diversification among stocks, to prevent any significant downside while limiting our upside. How do we diversify across asset classes? Luckily, we can purchase ETF's for almost anything: Gold ETF's (commodities), US bond ETF's (domestic bonds), International stock ETFs, Intl. bonds ETFs, etc. So, we can buy ETF's to give us exposure to various asset classes, thus diversifying among asset classes and within each asset class. Determining what % of our portfolio to put in any given asset class is known as asset allocation and some people say up to 90% of portfolio returns can be determined by asset allocation. That pretty much sums up passive management. The idea is to buy ETFs across asset classes and just leave them. You can readjust your portfolio holdings periodically, but otherwise there is no rapid trading. Now the other umbrella is active management. The unifying idea is that you can generate superior returns by stock selection. Active investors reject the idea of efficient markets. A classic and time proven strategy is value investing. After the collapse of 07/08, bank stocks greatly fell, but all the other stocks fell with them. Some stocks worth $100 were selling for $50. Value investors quickly snapped up these stocks because they had a margin of safety. Even if the stock didn't go back to 100, it could go up to $80 or $90 eventually, and investors profit. The main ideas in value investing are: have a big margin of safety, look at a company's fundamentals (earnings, book value, etc), and see if it promises adequate return. Coke has tremendous earnings and it's a great company, but it's so large that you're never going to make 20% profits on it annually, because it just can't grow that fast. Another field of active investing is technical analysis. As opposed to the \"\"fundamental analysis\"\" of value investing, technical analysis involves looking at charts for patterns, and looking at stock history to determine future paths. Things like resistance points and trend lines also play a role. Technical analysts believe that stocks are just ticker symbols and that you can use guidelines to predict where they're headed. Another type of active investing is day trading. This basically involves buying and selling stocks every hour or every minute or just at a rapid pace. Day traders don't hold onto investments for very long, and are always trying to predict the market in the short term and take advantage of it. Many individual investors are also day traders. The other question is, how do you choose a strategy? The short answer is: pick whatever works for you. The long answer is: Day trading and technical analysis is a lot of luck. If there are consistent systems for trading , then people are keeping them secret, because there is no book that you can read and become a consistent trader. High frequency trading (HFT) is an area where people basically mint money, but it s more technology and less actual investing, and would not be categorized as day trading. Benjamin Graham once said: In the short run, the market is a voting machine but in the long run it is a weighing machine. Value investing will work because there's evidence for it throughout history, but you need a certain temperament for it and most people don't have that. Furthermore, it takes a lot of time to adequately study stocks, and people with day jobs can't devote that kind of time. So there you have it. This is my opinion and by no means definitive, but I hope you have a starting point to continue your study.

Note that 'risk' here refers only to the variance in possible outcomes. By converting to EUR now (assuming you are moving to an EU country using the EUR), you eliminate the chance that the GBP will weaken. But you also eliminate the chance that the GBP will strengthen. Thus, you have reduced the variance in possible outcomes so that you have a 'known' amount of EUR. To put money in a different currency than what you will be using is a form of investing, and it is one that can be considered high risk. Invest in a UK company while you plan on staying in the UK, and you take on the risk of stock ownership only. But invest in a German company while you plan on staying in the UK, you take on the risk of stock ownership + the risk of currency volatility. If you are prepared for this type of risk and understand it, you may want to take on this type of risk - but you really must understand what you're getting into before you do this. For most people, I think it's fair to say that fx investing is more accurately called gambling [See more comments on the risk of fx trading here: https://money.stackexchange.com/a/76482/44232]. However, this risk reduction only truly applies if you are certain that you will be moving to an EUR country. If you invest in EUR but then move to the US, you have not 'solved' your currency volatility problem, you have simply replaced your GBP risk with EUR risk. If you had your plane ticket in hand and nothing could stop you, then you know what your currency needs will be in 2 years. But if you have any doubt, then exchanging currency now may not be reducing your risk at all. What if you exchange for EUR today, and in a year you decide (for all the various reasons that circumstances in life may change) that you will stay in the UK after all. And during that time, what if the GBP strengthened again? You will have taken on risk unnecessarily. So, if you lack full confidence in your move, you may want to avoid fully trading your GBP today. Perhaps you could put away some amount every month into EUR (if you plan on moving to an EUR country), and leave some/most in GBP. This would not fully eliminate your currency risk if you move, but it would also not fully expose yourself to risk if you end up not moving. Just remember that doing this is not a guarantee that the EUR will strengthen and the GBP will weaken.", "title": "" }, { "docid": "285560", "text": "\"If I invest in index funds or other long term stocks that pay dividend which I reinvest, they don't need to be worth more per share for me to make a profit, right? That is, if I sell part of the stocks, it's GOOD if they're worth more than I bought them at, but the real money comes from the QUANTITY of stocks that you get by reinvesting your dividends, right? I would say it is more the other way around. It is nice to get dividends and reinvest them, but overall the main gain comes from the stocks going up in value. The idea with index funds, however, is that you don't rely on any particular stock going up in value; instead you just rely on the aggregate of all the funds in the index going up. By buying lots of stocks bundled in an index fund, you avoid being too reliant on any one company's performance. Can I invest \"\"small amounts\"\" (part of paycheck) into index funds on a monthly basis, like €500, without taking major \"\"transaction fees\"\"?

And even then I'm wondering whether I'll really need ALL of my money in one go. Doesn't the index fund go back up eventually? Does a crash even matter if you plan on holding stocks for 10 or more years? Crashes always matter, because as you say, there's always the possibility that the crash will occur at a time you need the money. In general, it is historically true that the market recovers after crashes, so yes, if you have the financial and psychological fortitude to not pull your money out during the crash, and to ride it out, your net worth will probably go back up after a rough interlude. No one can predict the future, so it's possible for some unprecedented crisis to cause an unprecedented crash. However, the interconnectedness of stock markets and financial systems around the world is now so great that, were such a no-return crash to occur, it would probably be accompanied by the total collapse of the whole economic system. In other words, if the stock market dies suddenly once and for all, the entire way of life of \"\"developed countries\"\" will probably die with it.

The main financial products relevant to what you're describing are index funds (which you already mentioned) and index ETFs (which are basically similar with regard to the questions you're asking here). As far as concepts, the philosophy of buying low-fee index funds, holding them for a long time, and not selling during crashes, is essentially that espoused by Jack Bogle (not quite the inventor of the index fund, but more or less its spiritual father) and the community of \"\"Bogleheads\"\" that has formed around his ideas.

The higher your loan's interest rate, the more risky your investments will have to be in order to beat the interest rate. If you can get a return which beats the interest rates of your loan then congratulations! You have come out ahead and made a profit.

It's up to you to evaluate how much risk you're willing to take on to achieve a higher return.", "title": "" }, { "docid": "483123", "text": "\"The question is: how do you quantify investment risk? As Michael S says, one approach is to treat investment returns as a random variable. Bill Goetzmann (Yale finance professor) told me that if you accept that markets are efficient or that the price of an asset reflects it's underlying value, then changes in price represent changes in value, so standard deviation naturally becomes the appropriate measure for riskiness of an asset. Essentially, the more volatile an asset, the riskier it is. There is another school of thought that comes from Ben Graham and Warren Buffett, which says that volatility is not inherently risky. Rather, risk should be defined as the permanent loss of capital, so the riskiness of an asset is the probability of a permanent loss of capital invested. This is easy to do in casino games, based on basic probability such as roulette or slots. But what has been done with the various kinds of investment risks? My point is saying that certain bonds are \"\"low risk\"\" isn't good enough; I'd like some numbers--or at least a range of numbers--and therefore one could calculate expected payoff (in the statistics sense). Or can it not be done--and if not, why not? Investing is more art than science. In theory, a Triple-A bond rating means the asset is riskless or nearly riskless, but we saw that this was obviously wrong since several of the AAA mortgage backed securities (MBS) went under prior to the recent US recession. More recently, the current threat of default suggests that bond ratings are not entirely accurate, since US Treasuries are considered riskless assets. Investors often use bond ratings to evaluate investments - a bond is considered investment grade if it's BBB- or higher. To adequately price bonds and evaluate risk, there are too many factors to simply refer to a chart because things like the issuer, credit quality, liquidity risk, systematic risk, and unsystematic risk all play a factor. Another factor you have to consider is the overall portfolio. Markowitz showed that adding a riskier asset can actually lower the overall risk of a portfolio because of diversification. This is all under the assumption that risk = variance, which I think is bunk. I'm aware that Wall Street is nothing like roulette, but then again there must be some math and heavy economics behind calculating risk for individual investors. This is, after all, what \"\"quants\"\" are paid to do, in part. Is it all voodoo? I suspect some of it is, but not all of it. Quants are often involved in high frequency trading as well, but that's another note. There are complicated risk management products, such as the Aladdin system by BlackRock, which incorporate modern portfolio theory (Markowitz, Fama, Sharpe, Samuelson, etc) and financial formulas to manage risk. Crouhy's Risk Management covers some of the concepts applied. I also tend to think that when people point to the last x number of years of stock market performance, that is of less value than they expect. Even going back to 1900 provides \"\"only\"\" 110 years of data, and in my view, complex systems need more data than those 40,500 data points. 10,000 years' worth of data, ok, but not 110. Any books or articles that address these issues, or your own informed views, would be helfpul. I fully agree with you here. A lot of work is done in the Santa Fe Institute to study \"\"complex adaptive systems,\"\" and we don't have any big, clear theory as of yet. Conventional risk management is based on the ideas of modern portfolio theory, but a lot of that is seen to be wrong. Behavioral finance is introducing new ideas on how investors behave and why the old models are wrong, which is why I cannot suggest you study risk management and risk models because I and many skilled investors consider them to be largely wrong. There are many good books on investing, the best of which is Benjamin Graham's The Intelligent Investor. Although not a book on risk solely, it provides a different viewpoint on how to invest and covers how to protect investments via a \"\"Margin of Safety.\"\" Lastly, I'd recommend Against the Gods by Peter Bernstein, which covers the history of risk and risk analysis.

There are many new interventions for DR, but evidence to support their use is uncertain. OBJECTIVE: To review the best evidence for primary and secondary intervention in the management of DR, including diabetic macular edema. EVIDENCE ACQUISITION: Systematic review of all English-language articles, retrieved using a keyword search of MEDLINE (1966 through May 2007), EMBASE, Cochrane Collaboration, the Association for Research in Vision and Ophthalmology database, and the National Institutes of Health Clinical Trials Database, and followed by manual searches of reference lists of selected major review articles. All English-language randomized controlled trials (RCTs) with more than 12 months of follow-up and meta-analyses were included. Delphi consensus criteria were used to identify well-conducted studies. EVIDENCE SYNTHESIS: Forty-four studies (including 3 meta-analyses) met the inclusion criteria. Tight glycemic and blood pressure control reduces the incidence and progression of DR. Pan-retinal laser photocoagulation reduces the risk of moderate and severe visual loss by 50% in patients with severe nonproliferative and proliferative retinopathy. Focal laser photocoagulation reduces the risk of moderate visual loss by 50% to 70% in eyes with macular edema. Early vitrectomy improves visual recovery in patients with proliferative retinopathy and severe vitreous hemorrhage. Intravitreal injections of steroids may be considered in eyes with persistent loss of vision when conventional treatment has failed. There is insufficient evidence for the efficacy or safety of lipid-lowering therapy, medical interventions, or antivascular endothelial growth factors on the incidence or progression of DR. CONCLUSIONS: Tight glycemic and blood pressure control remains the cornerstone in the primary prevention of DR. Pan-retinal and focal retinal laser photocoagulation reduces the risk of visual loss in patients with severe DR and macular edema, respectively.

On the other hand, many studies have consistently shown that dietary restriction (DR) in rodents also decreases mitochondrial ROS (mtROS) production and oxidative damage to mitochondrial DNA and proteins. It has been observed that protein restriction also decreases mtROS generation and oxidative stress in rat liver, whereas neither carbohydrate nor lipid restriction change these parameters. This is interesting because protein restriction also increases maximum longevity in rodents (although to a lower extent than DR) and is a much more practicable intervention for humans than DR, whereas neither carbohydrate nor lipid restriction seem to change rodent longevity. Moreover, it has been found that isocaloric methionine restriction also decreases mtROS generation and oxidative stress in rodent tissues, and this manipulation also increases maximum longevity in rats and mice. In addition, excessive dietary methionine also increases mtROS generation in rat liver. These studies suggest that the reduced intake of dietary methionine can be responsible for the decrease in mitochondrial ROS generation and the ensuing oxidative damage that occurs during DR, as well as for part of the increase in maximum longevity induced by this dietary manipulation. In addition, the mean intake of proteins (and thus methionine) of Western human populations is much higher than needed.

DR is often referred to as calorie restriction, implying that reduced energy intake is responsible for its widespread and evolutionarily conserved benefits. However, recent data indicate dietary amino acid restriction as a key mediator of DR benefits. In fruitflies, an imbalance in essential amino acid intake is thought to underlie longevity benefits of DR. In mammals, reduced dietary protein or essential amino acid intake can extend longevity, improve metabolic fitness and increase stress resistance. In the present paper we review two evolutionarily conserved signal transduction pathways responsible for sensing amino acid levels. The eIF2α (eukaryotic initiation factor 2α) kinase GCN2 (general amino acid control non-derepressible 2) senses the absence of one or more amino acids by virtue of direct binding to uncharged cognate tRNAs. The presence of certain amino acids, such as leucine, permits activation of the master growth regulating kinase TOR (target of rapamycin). These two signal transduction pathways react to amino acid deprivation by inhibiting general protein translation while at the same time increasing translation of specific mRNAs involved in restoring homoeostasis. Together, these pathways may contribute to the regulation of longevity, metabolic fitness and stress resistance.", "title": "Amino acid sensing in dietary-restriction-mediated longevity: roles of signal-transducing kinases GCN2 and TOR" }, { "docid": "MED-2502", "text": "Dietary restriction (DR) without malnutrition is widely regarded to be a universal mechanism for prolonging lifespan.

New York:Random House (1975)], who asserted that elevated sensitivity to food additives underlies the signs of hyperactivity observed in some children. Although the evidence suggested that some unknown proportion of children did respond to synthetic food colors, the U.S. Food and Drug Administration (FDA) interpreted the evidence as inconclusive. A study published in 2007 [McCann et al. Food additives and hyperactive behaviour in 3-year-old and 8/9-year-old children in the community: a randomised, double-blinded, placebo-controlled trial. Lancet 370:1560–1567 (2007)] drew renewed attention to the hypothesis because of the study’s size and scope. It led the FDA to review the evidence, hold a public hearing, and seek the advice of its Food Advisory Committee. In preparation for the hearing, the FDA reviewed the available evidence and concluded that it did not warrant further agency action. Objectives: In this commentary I examine the basis of the FDA’s position, the elements of the review that led to its decision and that of the Food Advisory Committee, and the reasons that this is an environmental health issue. Discussion: The FDA review confined itself, in essence, to the clinical diagnosis of hyperactivity, as did the charge to the committee, rather than asking the broader environmental question of behavioral effects in the general population; it failed to recognize the significance of vulnerable subpopulations; and it misinterpreted the meaning of effect size as a criterion of risk. The FDA’s response would have benefited from adopting the viewpoints and perspectives common to environmental health research.

Methods and results Cell proliferation and cell cytotoxicity were measured by the MTT method, NF-κB activity by EMSA, protein expression by Western blot analysis, ROS generation by FACS analysis, and osteoclastogenesis by TRAP assay. Turmeric inhibited NF-κB activation and down-regulated NF-κB-regulated gene products linked to survival (Bcl-2, cFLIP, XIAP, and cIAP1), proliferation (cyclin D1 and c-Myc), and metastasis (CXCR4) of cancer cells. The spice suppressed the activation of STAT3, and induced the death receptors (DR)4 and DR5. Turmeric enhanced the production of ROS, and suppressed the growth of tumor cell lines. Furthermore, turmeric sensitized the tumor cells to chemotherapeutic agents capecitabine and taxol. Turmeric was found to be more potent than pure curcumin for cell growth inhibition.

It has been used for centuries to treat biliary disorders, anorexia, cough, diabetic wounds, hepatic disorders, rheumatism, and sinusitis. The preventive and therapeutic properties of curcumin are associated with its antioxidant, anti-inflammatory, and anticancer properties. Extensive research over several decades has attempted to identify the molecular mechanisms of curcumin action. Curcumin modulates numerous molecular targets by altering their gene expression, signaling pathways, or through direct interaction. Curcumin regulates the expression of inflammatory cytokines (e.g., TNF, IL-1), growth factors (e.g., VEGF, EGF, FGF), growth factor receptors (e.g., EGFR, HER-2, AR), enzymes (e.g., COX-2, LOX, MMP9, MAPK, mTOR, Akt), adhesion molecules (e.g., ELAM-1, ICAM-1, VCAM-1), apoptosis related proteins (e.g., Bcl-2, caspases, DR, Fas), and cell cycle proteins (e.g., cyclin D1). Curcumin modulates the activity of several transcription factors (e.g., NF-κB, AP-1, STAT) and their signaling pathways. Based on its ability to affect multiple targets, curcumin has the potential for the prevention and treatment of various diseases including cancers, arthritis, allergies, atherosclerosis, aging, neurodegenerative disease, hepatic disorders, obesity, diabetes, psoriasis, and autoimmune diseases.

Treatments were administered intravenously on day 1 of a 21-day cycle for four to six cycles. Pharmacokinetics, biomarkers, and antitumor activity were also evaluated. Results Figitumumab in combination with carboplatin and paclitaxel was well tolerated at doses up to 20 mg/kg; no dose-limiting toxicities were observed at this dose level.

By 1892 a simple working knowledge, then at hand, could have terminated the beriberi plague; however, orthodox medicine being then enchanted with the false concept that all disease was caused by germs, permitted millions of Asians to die needlessly of beriberi by refusing to tell them to eat rice bran or to drink rice bran tea. A second pandemic of heart attack deaths, called myocardial infarction (MI), struck the developed nations of the Western World in full force after 1930. As a hypothesis, it is suggested that this MI pandemic, still raging today, was caused by a change in food processing that occurred after 1920, when the new oil seed industry introduced into our food three greatly harmful lipid substances. The unnatural trans-trans isomer of linoleic acid, which had never been in human food prior to 1920 and which entered our food in margarines and refined oils, blocked the conversion of natural cis-cis linoleic acid to prostaglandin E1, which tends to prevent MI, both by acting as a vasodilator and by minimizing platelet aggregation. Harmful lactones were also introduced into our food, increasing the risk of MI by decreasing the fibrinolytic activity of our blood. The oil seed industry also introduced into our diet free radical lipid peroxides that make the myocardium more vulnerable to infarction. It is suggested that except for the one in 500 of us who is afflicted by familial hypercholesterolemia, the cholesterol concept of MI is as false today as was the concept in 1900 that germs caused beriberi.

Data were collected on pet ownership, drinking water and other risk factors for gastroenteritis. Overall 89% of households had pets and dog ownership was more common than cat ownership. The multivariable models for gastroenteritis and pet ownership indicated that living in a household with a dog or cat was associated with a reduced risk of gastroenteritis (adj. OR 0·71, 95% CI 0·55–0·92; OR 0·70, % CI 0·51–0·97 respectively). This paper adds to the evidence that pets are not a major source of gastroenteritis in the home and lends support to the health benefits of pet ownership. However, this must be weighed against the potential negative consequences, such as dog bites, particularly for this age group.", "title": "Does dog or cat ownership lead to increased gastroenteritis in young children in South Australia?" } ]
