grape seed extract
Grape Seed Extract (GSE) is an herbal preparation made from grapes. This extract contains oligomeric proanthocyandin (OPC), an important antioxidant.
It is a natural plant constituent which strengthens and protects living tissue.
Researchers reveals GSE alsomay help skin wounds heal faster and with less scarring.

The benefit of grape seed extract can be associated the substance called oligomeric proanthocyandin that can found in grape seeds extract.
Before Grape seed extract was discovered by a French biochemist the best sources of antioxidants came from vitamin C,
E, and beta-carotene; however, these sources were not powerful enough to fight the free radicals. Grape seed extract contains the substance called oligomeric proanthocyandin. This substance is said to improve blood circulation and to have some protective properties against heart disease.
Experimental data does suggest that grape seed also has anti-inflammatory and anti-carcinogenic properties and prevents the formation of plaque in the arteries. All of this information is great for cardiovascular health.
Grape seed extract has also proven to be valuable in the treatment of inadequate blood flow in the capillaries and veins. Small studies have shown increased capillary strength using as little as 50 milligrams/day, and increased venous blood flow using 150 milligrams/day.
Collagen and elastin are two proteins found in connective tissue that support organs, joints, and muscles. By nourishing blood vessel walls and performing other renewing functions, grape seed extract helps promote healthy blood pressure levels, heart health, and a proper inflammation response.

It is possible to fight off aging with grape seed extract due largely to the antioxidant effect of the phytochemicals contained within the seed of the grape. The seed is rarely absorbed by your body because it is so difficult for your digestive juices to break down; significantly more difficult than the skin or the pulp. So what is specific about the seed that makes it so useful as a source of antioxidants? That shall be discuss shortly, but for now let’s discuss the causes of aging, and how antioxidants can help to keep them at bay.

To fight off aging you have to understand what causes it, and the take steps to avoid these causes. It is fairly obvious that all causes of aging cannot be circumvented, but there are things that can be done to keep some of them at bay. Here, we are specifically concerned with the aging of your skin, which is the most visible form of aging. The first aspect of aging to understand is that there are two types: intrinsic and extrinsic.

Intrinsic Aging

Intrinsic aging is natural aging, and is largely genetic. Starting when you are fairly young, normally in the early to mid 20s, intrinsic aging is typified by wrinkling, hair loss or graying of the hair, hollowing of cheeks and other areas where the fat underneath the skin that normally contributes to your physical appearance is lost, and also bone loss that causes your skin to sag due a gradual loss of the structure that sculpts your physical appearance.

The age at which this occurs, and its speed is determined by your genes; although the process generally begins around the mid 20s, the speed with which it progresses is genetically controlled.

Extrinsic Aging

This is where grape seed extract can help. Extrinsic aging is not genetic, but environmental. Ten majority of this type of aging is due to exposure to the damaging UV light of the sun, which cause the typical ‘leathery’ look of the skin of people raised in areas such locations as the hotter parts of Australia and the USA, without the benefit of the native skin pigmentation that filters out these harmful ultra-violet rays.

Other factors that can cause the same degradation of your skin cells are smoking, the way you sleep and gravity. The sun generates free radicals (more on these later) that can destroy skin cells, cause freckles, leathery skin and a blotched complexion and also skin cancer. Smokers are more likely to develop leathery and wrinkled skin than non-smokers, and as the elasticity of your skin reduces, gravity cause jowls to develop and also a more pronounced lower lip.

Even your sleeping position can make you appear to age quicker, particularly using the same sleeping position on your pillow each night that cause what are known as sleep lines, that are really wrinkles that are difficult, if not impossible to remove. However, one of the most relevant factors is pollution, and the effects of car emissions, pesticides and other agricultural chemicals, paint fumes and 1001 other forms of chemical pollution that produce free radicals.

Where grape seed extract is involved in fighting off aging is in extrinsic aging is by destroying the free radicals. All substances, from the air to the oceans, are formed of atoms that contain electrons. Stable molecules contain an even number of electrons, or what are known as ‘electron pairs’. When a molecule loses one electron it is known as a free radical, whose prime purpose in its very short life is to steal an electron from the nearest molecule. This ’short’ lifetime can as long as a day or as short as thousandth of a second: it depends on is size and the degree of steric hindrance to the reaction with the spare electron.

Now that the reasons for aging and the nature of free radicals are better understood it is easier for you understand why grape seed extract can help to fight aging caused by the effects of free radicals on your skin.

Grape seed is a waste product of the wine industry. You cannot make wine from grape seeds, so they are removed from the final product by filtration or sedimentation. It contains a large number of phytonutrients, the most important being polyphenols in the form of flavanoids, lipids and carbohydrates. It also contains proteins that don’t have much of an effect on aging. Flavonoids (also spelled flavanoids) are powerful antioxidants that destroy free radicals; they are twenty times as powerful as Vitamin E and over fifty times more powerful an antioxidant than Vitamin C.

Both of these vitamins are regarded as strong antioxidants in their own right, which is an indication of how good grape seed extract is at killing free radicals. It’s like a combination of Harry Callahan, Paul Kersey, John McClane and the whole of the Magnificent Seven after the scavengers in your body cells. They succeed, and do it in spades!

Not only do the ingredients of grape seed extract kill off free radicals with the efficiency of a Delta Task Force, but are also anti-allergenic, anti-inflammatory, anti-cancer and anti just about anything else you can think of. However, let’s have an even closer look and find out exactly what polyphenols are present in this so-called wonder juice.

Procyanadin was originally named Vitamin P in 1936 by its discoverer, Prof. Jacques Masquelier, and is believed to bond with collagen to protect you from premature aging by retaining and even improving the elasticity of your skin. An added benefit is that it also improves the elasticity of your blood vessels, and so helps to fight off the effects of high blood pressure and places less strain on your heart. The overall effect on your face is to practically give you a chemical face lift and also provide protection from the damaging effect of the UV component of sunlight through its lethal attitude towards the free radicals that UV radiation generates.

Another component of grape seed extract particularly that of muscadine grapes is resveratrol; a phytoalexin that has strong anti-inflammatory properties and can also fight off the effects of aging. Phytoalexins are antibiotics produced by plants that are under attack, and, in addition to helping you age slower, confers other benefits to your body including helping your brain to carry out its work more efficiently.

All in all, grape seed extract confers many benefits to your health and is also believed to possess powerful anti-cancer properties. However, it is for its ability to fight off aging that most people use it as a supplement, and in this respect it has been found to be extremely effective. Any antioxidant is of benefit to your body, but grape seed extract is of particular benefit due its high antioxidant potency.

There are more new cases of Americans infected with HIV, the virus that causes AIDS, than previously believed, the Centers for Disease Control and Prevention said Saturday.

About 56,000 people became infected with HIV in the past year, which translates to about 40 percent more cases than officials had estimated, said Dr. Kevin Fenton, director of the CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD and TB Prevention.

Previous CDC estimates suggested about 40,000 new people were infected each year. But those estimates used “limited data and less precise methods,” said the center, which is now using technology capable of determining when someone was infected.

The new method can indicate whether someone has been infected with HIV during the previous five months, rather than relying on statistical models.

Diagnosis of HIV can occur years after infection, he said.

“The fact that 56,000 Americans each year are contracting HIV for the first time is a wake-up call for all of us in the U.S.,” Fenton said. iReport.com: Are you living with HIV infection? Share your story

“These numbers are a scathing indictment of how profoundly U.S. and CDC HIV prevention efforts have failed,” said Michael Weinstein, president of AIDS Healthcare Foundation, which calls itself “the nation’s largest provider of HIV/AIDS medical care.”

Weinstein called on the United States to appropriate $200 million for the testing of 10 million people over the next three years.

“Identifying all those who are infected and linking them to treatment is the only way to break the chain of new infections and begin to address the nation’s runaway epidemic,” he said.

In the United States, more than 1 million people are living with HIV, and about one-fourth of them are unaware they have the virus, the CDC said.

According to the report, 53 percent of new HIV infections occur in homosexual or bisexual men. African-Americans account for 45 percent, or 25,000 new cases annually, meaning they are seven times more likely to contract HIV than whites.

In Washington, D.C., 80 percent of people living with HIV are African-American, according to Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health.

On Tuesday, the California-based think tank Black AIDS Institute released a report that suggests that the AIDS epidemic among African-Americans in parts of the United States is as severe as it is in parts of Africa.

If African-Americans made up their own country, it would rank 16th globally in the number of people living with HIV, said Black AIDS Institute founder Phill Wilson.

The number of people newly infected has remained relatively stable since the late 1990s, and the more accurate estimate does not change that, the CDC said.

Wilson said the numbers were especially startling considering that the United States lacked the infrastructure to handle 40,000 new HIV cases each year.

Now, with the numbers as high as 56,000 a year, it’s even worse, he said.

“We do not have a national AIDS strategy,” said Wilson, suggesting that the new numbers should translate into a “national call to action.”

Fenton acknowledged more needs to be done, but said the CDC was bound to operate within “the president’s budget.”

Ideally, he said, a response to the epidemic would include more investment in prevention efforts. The CDC will work with the Department of Health and Human Services, along with other public and private organizations, to “add to the federal pot,” he said.

“Every year, more than 15,000 people are dying from this disease, and AIDS is a major killer for some of our minority communities,” he said.

“The key thing we have to focus on now is what, how and when do we begin to enhance the prevention responses to end this epidemic.”

Fenton and Wilson said removing stigma and discrimination are necessary first steps. People need to be educated about how they can prevent infection and, if they do get HIV, how they can get tested and treated as soon as possible.

Since the mid-1990s, antiretroviral therapies have turned HIV and AIDS into more of a chronic illness rather than a death sentence. Until a vaccine is developed, getting infected people on antiretrovirals as early as possible would improve their long-term outcome.

The new data is scheduled for publication in the peer-reviewed Journal of the American Medical Association. The report’s release is meant to coincide with the opening Sunday of the the biannual International AIDS Conference in Mexico City, Mexico.

AFP - HIV infection rates among gay men in many parts of Asia are as severe as those which devastated US homosexual communities in the late 1980s, top officials of the UNAIDS agency said here Tuesday.

Launching his agency’s 2008 report on the global AIDS epidemic, Peter Piot, UNAIDS executive director, urged more action to prevent the spread of the disease among gay men who have unsafe sex and stressed the importance of working with affected communities.

“All over Asia there are now epidemics of HIV in men who have sex with men of the same magnitude that we saw in this country 25 years ago,” Piot said.

“That is something that has been detected fairly recently. There is not enough action yet but we are now starting programs,” he added.

Paul De Lay, director of Evidence, Monitoring and Policy at UNAIDS, said the HIV epidemic among gay communities in Asia was not new, but that it had recently reached the levels seen in cities such as San Francisco at the end of the 1980s when HIV infections reached their peak.

He said it could be due to a number of factors, including less funding for programs that target men who have sex with men and the fact that there were new groups who were less aware of the risks of unprotected sex.

“Asia has recognized populations of men who have sex with men for quite some time,” he told AFP. “The epidemic in these populations started in the mid-1990s. What we see now is a resurgence.”

“There are countries where the percentage of people infected are similar to what we were seeing in San Francisco or in Berlin or in London where up to 15 to 20 percent of men who have sex with men are HIV positive,” he added.

The report meanwhile noted that unprotected sex between men was a “potentially significant but under-researched aspect of the HIV epidemics in Asia,” citing countries such as Thailand and Vietnam.

“Recent study data from several major cities in the region, from Bangkok to Ho Chi Minh City, show increasing HIV prevalence among men who have sex with men,” the report said.

In China, unsafe sex between men could account for up to seven per cent of HIV infections, it noted.

De Lay said there were also high infection rates among gay populations in cities such as Chennai and Mumbai in India and in Indonesia’s capital Jakarta.

He added that these communities often faced homophobia from the wider population, as well as discrimination from health care providers, which discouraged them from seeking information and getting tested.

“Even without blatant national laws that criminalize homosexual behavior, you can still have a gradation of policies and practices that can be almost as bad,” he said.

De Lay pointed to a similar resurgence of HIV infections among gay populations in the US and western Europe, which he said showed the need for constant vigilance.

The report said higher risk unprotected sex among gay men in several countries in western Europe, such as Germany, appeared to be linked to the increasing numbers of new HIV diagnoses among that group.

“It’s disturbing because it’s this sense that we can never let our guard down as far as prevention, that the epidemic will come creeping back if there isn’t this constant attention being paid to it,” De Lay said.
