Scientists Have Developed A Safe And Reliable Stool Test That Can Detect The Earliest, Curable Stages Of Colon Cancer
Scientists at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins have developed a safe and reliable stool test that can detect the earliest, curable stages of colon cancer. Early studies of the test, which uses a newly developed technology to detect and highlight a key genetic marker of the disease, are reported in the January 31, 2002, issue of the New England Journal of Medicine, and are the culmination of more than a decade of effort to uncover disease mutations and apply them to screening and early detection. more

Medical College Of Wisconsin Researchers Find Genetic Markers Linked To Heart Attacks
In the largest study of its kind to date, an international team led by researchers at the Medical College of Wisconsin has localized a region of the human genome linked to the development of heart attacks. The same site is linked to coronary artery disease (CAD), a condition in which the arteries narrow due to a build up of plaque. more

Intellectual Resources May Help Soldiers Stave Off Post-Traumatic Stress Disorder
Greater intellectual resources may, according to a new study of Vietnam veterans, help buffer soldiers from developing post-traumatic stress disorder (PTSD) after combat. These findings appear in the January issue of Neuropsychology, published by the American Psychological Association (APA). more

Functional Brain Imaging Links Two Key Pieces Of Schizophrenia Puzzle
Using functional brain imaging, National Institute of Mental Health scientists for the first time have linked two key, but until now unconnected, brain abnormalities in schizophrenia. They have shown that the less patients' frontal lobes activate during a working memory task, the more the chemical messenger dopamine, thought to underlie the delusions and hallucinations of schizophrenia, rises abnormally in the striatum, a relay station deep in the brain. Together with other evidence, this suggests that the excess dopamine activity that antipsychotic drugs quell may be driven by a defect in the prefrontal cortex, the brain's executive control center. Andreas Meyer-Lindenberg, M.D., Karen Berman, M.D., and colleagues report on their PET (positron emission tomography) study, published online 28 January 2002, in Nature Neuroscience. more

Vidyya Cancer Facts: Lifetime Probability Of Breast Cancer In American Women
A report from the National Cancer Institute (NCI) estimates that about 1 in 8 women in the United States (approximately 12.8 percent) will develop breast cancer during her lifetime. However, this statement, though oft repeated, is poorly understood. You might be surprised by what "1 in 8" really means. more
