Certain preparations taken to enhance athletic performance or stave off disease contain an anti-oxidant that could cause harm. According to new research at the University of Virginia Health System, N-acetylcysteine (NAC), an anti-oxidant commonly used in nutritional and body-building supplements, can form a red blood cell-derived molecule that makes blood vessels think they are not getting enough oxygen.
Laboratory experiments show that an extract of the skin of muscadine grapes can inhibit growth of prostate cancer cells in the laboratory. Investigators from the National Cancer Institute (NCI), part of the National Institutes of Health, and their research partners also show that muscadine grape skin extract (MSKE) does not contain significant amounts of resveratrol, another grape skin component that has been widely studied and shown to be of potential benefit in preventing prostate cancer growth.
A new method for fighting skin wrinkles has been developed at the Hebrew University Faculty of Agriculture, Food and Environmental Quality Sciences.

It?s yet another example of how a good thing can go bad: Researchers have found evidence in laboratory studies that ?good? cholesterol, renowned for its ability to protect against heart disease, can undergo detrimental changes in protein composition that make it ?bad? for the heart.
Cancer, cardiovascular diseases, Parkinson?s and Alzheimer?s are often linked to DNA damage that occurs when metal ions in the body such as iron and copper produce reactive oxygen compounds that damage human cells.
Findings from a study released revealed that a limited amount of clinical research exists to prove the effectiveness of many over-the-counter (OTC) anti-aging products.
Vitamins C and E and beta carotene, either individually or in combination, do not appear to reduce the risk of cardiovascular events or death among women at high risk for heart disease, according to a report in the August 13/27 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Antioxidants are widely considered an important defense against heart disease, but University of Utah researchers have found excessive levels of one antioxidant?reduced glutathione?actually may contribute to the disease.
Concentrated chemicals derived from green tea dramatically boosted production of a group of key detoxification enzymes in people with low levels of these beneficial proteins, according to researchers at Arizona Cancer Center.
