A drug prescribed for male and female infertility and menstrual disorders could hold the key to a more effective treatment for alcoholism, according to a study by researchers at the UCSF-affiliated Ernest Gallo Clinic and Research Center. http://www.physorg.com/news154634122.html Medicine & Health Mon, 23 Feb 2009 17:55:45 EST news154634122 A paper published online today in Nature Neuroscience reveals the presence of methyl CpG binding protein 2 (MeCP2) in glia. MeCP2 is a protein associated with a variety of neurological disorders, including Rett Syndrome, the most physically disabling of the autism spectrum disorders. The researchers show that MeCP2-deficient astrocytes (a subset of glia) stunt the growth of neighboring neurons. Remarkably, these neurons can recover when exposed to normal glia in culture. http://www.physorg.com/news154610775.html Medicine & Health Mon, 23 Feb 2009 11:48:25 EST news154610775 (PhysOrg.com) -- To measure anxiety in a mouse and suggest it`s similar to anxiety in a person may seem like a stretch, but the metrics sound uncannily familiar.

These disorders -- which include depression, anxiety, conduct disorder, and substance abuse -- are about as common as fractured limbs in children and adolescents. Collectively, they take a tremendous toll on the well-being of young people and their families, costing the U.S. an estimated $247 billion annually, the report says. http://www.physorg.com/news153756622.html Medicine & Health Fri, 13 Feb 2009 14:10:51 EST news153756622 Long bone fractures heal faster after injections of bone-building cells. Research published in the open access journal BMC Musculoskeletal Disorders has shown that osteoblast cells cultured from a patient's own bone marrow can be injected into the fracture area and can speed the healing process. http://www.physorg.com/news153650980.html Medicine & Health Thu, 12 Feb 2009 08:50:09 EST news153650980 In 2005, a woman who had trouble sleeping asked Siong-Chi Lin, M.D., for help. Dr. Lin, a sleep disorders specialist at the Mayo Clinic campus in Florida, diagnosed restless legs syndrome. This common neurologic disorder interrupts sleep because of unpleasant sensations in the legs at rest, especially in the evening, that are temporarily relieved by movement. http://www.physorg.com/news152898967.html Medicine & Health Tue, 03 Feb 2009 15:56:54 EST news152898967 A study by National Institutes of Health (NIH) researchers has revealed surprising new insights into the process used to initially identify an experimental drug now being tested in people with cystic fibrosis and muscular dystrophy. Researchers emphasized that the clinical implications of their findings are unclear, but said the results suggest more work may be needed to make sure the screening process to select promising agents was not flawed by its effects on a firefly enzyme used as a marker. The study was published today in the Proceedings of the National Academy of Sciences (PNAS). http://www.physorg.com/news152880070.html Medicine & Health Tue, 03 Feb 2009 10:49:20 EST news152880070 Does the mere availability of something tempting weaken the will to resist? The answer is of more than theoretical interest to public health experts, and the problem goes far beyond serious addictive disorders. Just think of all those Christmas cookies in your office recently.

Tracing the history of these changes within the proteins coded by the Msx gene family over the past 600 million years has also provided additional evidence for the ancient origin of the human mouth. http://www.physorg.com/news151141584.html Biology Wed, 14 Jan 2009 07:46:24 EST news151141584 A new study provides a novel theory for how delusions arise and why they persist. NYU Langone Medical Center researcher Orrin Devinsky, MD, performed an in-depth analysis of patients with certain delusions and brain disorders revealing a consistent pattern of injury to the frontal lobe and right hemisphere of the human brain. The cognitive deficits caused by these injuries to the right hemisphere, leads to the over compensation by the left hemisphere of the brain for the injury, resulting in delusions. The article entitled "Delusional misidentifications and duplications: Right brain lesions, left brain delusions" appears in the latest issue of the journal of Neurology. http://www.physorg.com/news151069576.html Medicine & Health Tue, 13 Jan 2009 11:46:16 EST news151069576 A Mayo Clinic-led international consortium has found a mechanism that may help explain Parkinson's and other neurological disorders. http://www.physorg.com/news150904281.html Medicine & Health Sun, 11 Jan 2009 13:51:21 EST news150904281 (PhysOrg.com) -- A naturally occurring DNA repair system that normally protects cells from damage can cause retinal degeneration and blindness when overstimulated, according to a new study by MIT researchers. http://www.physorg.com/news150727857.html Medicine & Health Fri, 09 Jan 2009 12:50:57 EST news150727857 There are no sheep keeping Mari A. company at bedtime.
