Grape Extract Inhibits Prostate Cancer Cell Growth (9/1/2007)

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. The results appear in the September 1, 2007, issue of Cancer Research. ...> Full Article

Research Shows Estrogen Protects Women's Brains Prior to Menopause: Ovary Removal Before Menopause Increases Risk of Parkinson's Disease and Parkinsonism (8/31/2007)

Mayo Clinic researchers have shown that women who had one or both ovaries removed before menopause faced an increased long-term risk of Parkinson's disease and of several related conditions known as parkinsonism, compared to women who retained their ovaries. To protect against these conditions, estrogen replacement therapy may be warranted for women who had their ovaries removed before menopause. Ovaries are responsible for estrogen production. This study, the largest of its kind, appears in the Aug. 29 online edition of the journal Neurology, the medical journal of the American Academy of Neurology. ...> Full Article

Disease Resistance may be Genetic (8/31/2007)

According to a study in Evolution, resistance to certain infectious diseases may be passed genetically from parent to child. The genetic resistance may be beneficial to families as those with the gene are both unlikely to suffer from disease and unlikely to carry the disease home. Paul Schliekelman, author of the study, says the research was inspired by personal experience after catching stomach flus from his daughter three times over a six-month period. ...> Full Article

Bleeding, Not Inflammation, Is Major Cause of Early Lung Infection Death (8/30/2007)

Researchers believe they have discovered why a bacterial lung infection is so lethal in the early stages, and it's not what medical authorities had thought, according to research published today in the journal Immunity. The study reveals for the first time that a toxin released by bacteria causes severe bleeding in the lungs by patients with pneumococcal pneumonia. It is the bleeding, the authors argue, not inflammation as once thought, which makes the infections deadly. The same study also reveals why antibiotics often fail to help prevent early death. ...> Full Article

Improved Fertilization And Perhaps Gender Selection With New Sperm Sorting Technique (8/30/2007)

Researchers at the University of California, Irvine (UCI) and San Diego (UCSD), have developed a rapid new sorting technique for sperm using a laser trap that can separate stronger, faster sperm from slower sperm. Faster sperm are more likely to successfully fertilize an egg, so the technique could improve the chances of conception via in vitro fertilization by ensuring that only the fastest, strongest sperm are used. The technique could find wide application in animal husbandry and human fertility treatments. ...> Full Article

Discovery Could Help Stop Malaria at Its Source - the Mosquito (8/30/2007)

As summer temperatures cool in the United States, fewer mosquitoes whir around our tiki torches. But mosquitoes swarming around nearly 40 percent of the world's population will continue to spread a deadly parasitic disease �" malaria. Now an interdisciplinary team led by researchers from Rensselaer Polytechnic Institute has found a key link that causes malarial infection in both humans and mosquitoes. ...> Full Article

Novel Method Enables Genomic Screening of Blood Vessels from Patient Tissue (8/29/2007)

Scientists have developed a new method of capturing a complete genome-wide screening of blood vessel cells in their actual disease state, advancing the potential for genetic research on the tissue responsible for delivering nourishment that can accelerate the growth of both a cancer tumor or wound healing. ...> Full Article

Scientists reveal the actions of a key player in colorectal cancer (8/29/2007)

Colorectal cancer is one of the most prevalent cancers in the Western world. The tumor starts off as a polyp but then turns into an invasive and violent cancer, which often spreads to the liver. In an article recently published in the journal Cancer Research, Prof. Avri Ben-Ze'ev and Dr. Nancy Gavert of the Weizmann Institute's Molecular Cell Biology Department reveal mechanisms that help this cancer metastasize. ...> Full Article

Researchers Uncover Genetic Components of Aging (8/27/2007)

People who live to 100 or more are known to have just as many-and sometimes even more-harmful gene variants compared with younger people. Now, scientists at the Albert Einstein College of Medicine of Yeshiva University have discovered the secret behind this paradox: favorable "longevity" genes that protect very old people from the bad genes' harmful effects. The novel method used by the researchers could lead to new drugs to protect against age-related diseases. ...> Full Article

Soda Warning? New Study Supports Link Between Diabetes, High-Fructose Corn Syrup (8/27/2007)

Researchers have found new evidence that soft drinks sweetened with high-fructose corn syrup (HFCS) may contribute to the development of diabetes, particularly in children. In a laboratory study of commonly consumed carbonated beverages, the scientists found that drinks containing the syrup had high levels of reactive compounds that have been shown by others to have the potential to trigger cell and tissue damage that could cause the disease, which is at epidemic levels. They reported here today at the 234th national meeting of the American Chemical Society. ...> Full Article
