Mutation may raise prostate-cancer risk in African Americans

Researchers have identified a gene mutation that may increase the risk of prostate cancer up to three times in African-American men with a family history of the disease. more  

Surprising new study shows periodontal disease affects young adults, boosts pregnancy problems

Periodontal disease -- a progressive, eventually painful and disruptive condition in which bacteria attack gums and the hidden roots of teeth -- develops much earlier than dentists and other health professionals thought, a major new study concludes. more

Americans think commitment to health research should be stronger

Most Americans rate medical research as a high national priority and strongly support greater public and private funding, according to an article in the September 21 issue of JAMA, a theme issue on medical research. However, recent opinion surveys indicate that Americans also are increasingly dissatisfied with the nation's health care system and think the national commitment to health-related research should be higher. more  

Increased ovarian cancer risk not found in women with breast cancer family history

Women with a strong family history of breast cancer but who don't have breast cancer genetic mutations can now be reassured that they are not at increased risk for ovarian cancer, according to a new study by researchers at Memorial Sloan-Kettering Cancer Center (MSKCC). The work, published in the September 21, 2005, issue of the Journal of the National Cancer Institute, is one of the first prospective studies to allow doctors to tailor ovarian cancer screening recommendations for women with a family history of breast cancer but with no identifiable BRCA mutation. more

Less virulent strains of avian influenza can infect humans  

In findings with implications for pandemic influenza, a new study reports for the first time that a less-virulent strain of avian influenza virus can spread from poultry to humans. The research appears in the October 1 issue of The Journal of Infectious Diseases, now available online. more

Green tea ingredient prevents Alzheimer's-like brain damage in mice  

Researchers at the University of South (USF) have found that green tea may offer another potential health benefit -- protecting the brain against the ravages of Alzheimer's disease. In an article published Sept. 21 in the Journal of Neuroscience, USF researchers report that a component of green tea prevented Alzheimer's-like damage in the brains of mice genetically programmed to develop the neurodegenerative disease process. The component, called epigallocatechin-3-gallate (EGCG), is a major antioxidant in green tea and has been widely studied for its reported protection against certain cancers. more

Targeting a key enzyme with gene therapy reversed course of Alzheimer's disease in mouse models

In mice, that had been genetically engineered to develop Alzheimer's disease, scientists were able to reverse the rodents' memory loss by reducing the amount of an enzyme that is crucial for the development of Alzheimer's disease. more
