The study reveals that while virtually all of the women admitted to,experiencing some level of emotional distress, 47 percent met clinically significant screening criteria for emotional distress or a psychiatric disorder, including major depression and post-traumatic stress disorder (PTSD)........ ]]> http://www.networlddirectory.com/blogs/permalinks/11-2006/to-slow-aids-in-russia-treat-hiv-positive-addicts.html http://www.networlddirectory.com/blogs/permalinks/11-2006/to-slow-aids-in-russia-treat-hiv-positive-addicts.html Sun, 25 Feb 2007 03:05:09 GMT The key to combating AIDS in Russia may be to treat HIV-infected drug users. A new model estimating the spread of HIV in Russia suggests that treating injection drug users with antiretroviral medicine will slow transmission of the virus among the general population. The study, which will appear in the recent issue of the journal AIDS, was led by Douglas Owens, MD, a researcher at the Veterans Affairs Palo Alto Health Care System and professor of medicine at the Stanford University School of Medicine, and Margaret Brandeau, PhD, professor of engineering at Stanford........ ]]> http://www.networlddirectory.com/blogs/permalinks/11-2006/antioxidant-therapies-and-radiation-treatment.html http://www.networlddirectory.com/blogs/permalinks/11-2006/antioxidant-therapies-and-radiation-treatment.html Sun, 25 Feb 2007 03:05:09 GMT Cancer patients can get the vital nutritional benefits from taking antioxidants without the risk of interfering with radiation therapy, as per research findings being presented this weekend at the Society of Integrative Oncology's Third International Conference in Boston.

Adam Dicker, M.D., Ph.D., professor of radiation oncology at Jefferson Medical College and his co-workers used an increasingly common animal model, the zebrafish, and antisense technology to show that the drug flavopiridol works by blocking the activity of the gene, cyclin D1, which is made in excessive amounts in about half of all breast cancers. Using similar techniques in the future, the scientists say, may enable researchers to better gauge the effects of drugs........ ]]> http://www.networlddirectory.com/blogs/permalinks/11-2006/about-reading-difficulty.html http://www.networlddirectory.com/blogs/permalinks/11-2006/about-reading-difficulty.html Sun, 25 Feb 2007 03:05:09 GMT At least one in three children in this country has difficulty learning to read. Research shows that children's aggressive behavior and reading difficulties during early elementary school years are risk factors for adolescent problem behaviors such as delinquency, academic failure, and substance use. Oregon Research Institute (ORI) researchers recently received high marks for their work to reverse this trend........ ]]> http://www.networlddirectory.com/blogs/permalinks/11-2006/gene-shapes-brain-region.html http://www.networlddirectory.com/blogs/permalinks/11-2006/gene-shapes-brain-region.html Sun, 25 Feb 2007 03:05:09 GMT A gene variant linked to mental illness goes hand-in-hand with enlargement of a brain region that handles negative emotions, scientists at UT Southwestern Medical Center and the Central Texas Veterans Health Care System have found. The region of the brain called the pulvinar is larger and contains more nerve cells in humans who carry the gene........ ]]> http://www.networlddirectory.com/blogs/permalinks/11-2006/one-millisecond-after-head-hits-car-windshield.html http://www.networlddirectory.com/blogs/permalinks/11-2006/one-millisecond-after-head-hits-car-windshield.html Sun, 25 Feb 2007 03:05:09 GMT Research by a Sandia National Laboratories engineer and a University of New Mexico Health Sciences Center neurologist shows that brain injury may occur within one millisecond after a human head is thrust into a windshield as a result of a car accident. This happens prior to any overall motion of the head following impact with the windshield and is a new concept to consider for doctors interested in traumatic brain injury (TBI)........ ]]> http://www.networlddirectory.com/blogs/permalinks/11-2006/pounding-heart-and-sweaty-palms.html http://www.networlddirectory.com/blogs/permalinks/11-2006/pounding-heart-and-sweaty-palms.html Sun, 25 Feb 2007 03:05:09 GMT People who get scared when they experience a pounding heart, sweaty palms or dizziness -- even if the cause is something as mundane as stress, exercise or caffeine -- are more likely to develop a clinical case of anxiety or panic disorder, according to a Florida State University researcher in Tallahassee, Fla........ ]]> http://www.networlddirectory.com/blogs/permalinks/11-2006/the-lousebuster.html http://www.networlddirectory.com/blogs/permalinks/11-2006/the-lousebuster.html Sun, 25 Feb 2007 03:05:09 GMT University of Utah biologists invented a chemical-free, hairdryer-like device the LouseBuster and conducted a study showing it eradicates head lice infestations on children by exterminating the eggs or "nits" and killing enough lice to prevent them from reproducing. The study reported in the November 2006 issue of the journal Pediatrics "shows our invention has considerable promise for curing head lice," says Dale Clayton, a University of Utah biology professor who led the research and co-invented the machine........ ]]> http://www.networlddirectory.com/blogs/permalinks/11-2006/smoking-radiation-and-prostate-cancer.html http://www.networlddirectory.com/blogs/permalinks/11-2006/smoking-radiation-and-prostate-cancer.html Sun, 25 Feb 2007 03:05:09 GMT Smoking has been found to contribute to poorer outcomes for people treated for a number of kinds of cancer and now, scientists at Fox Chase Cancer Center have associated smoking and acute side-effects following radiation treatment for prostate cancer.

Published in the scientific journal Cancer Research today, the study not only illustrates a way to prevent the disease but also provides further insight into the mechanisms of the disease, which could lead to novel therapies. Using animal models, the MUHC study is the first to demonstrate directly that diets low in folate cause colorectal cancer, and follows on the heels of earlier research by the same team that revealed how high folate diets can protect against heart disease........ ]]> http://www.networlddirectory.com/blogs/permalinks/11-2006/computer-with-brain-connections.html http://www.networlddirectory.com/blogs/permalinks/11-2006/computer-with-brain-connections.html Sun, 25 Feb 2007 03:05:09 GMT Fundamental theories regarding consciousness, emotion and quality of life in sufferers of paralysis from Amyotrophic Lateral Sclerosis (ALS, also known as 'Lou Gerhig's disease') are being challenged based on new research on brain-computer interaction. ALS is a progressive disease that destroys neurons affecting movement. The study appears in the latest issue of Psychophysiology. The article reviews the usefulness of currently available brain-computer -interfaces (BCI), which use brain activity to communicate through external devices, such as computers........ ]]>
