Young animals treated with commonly-prescribed drugs develop behavioral abnormalities in adulthood say researchers at Georgetown University Medical Center. The drugs tested include those used to treat epilepsy, mood disorders and pain. http://www.physorg.com/news175271238.html Medicine & Health Tue, 20 Oct 2009 18:10:02 EST news175271238 New data about amyloid precursor protein, or APP, a protein implicated in development of Alzheimer's disease, suggests it also may have a positive role -- directly affecting learning and memory during brain development. So is APP good or bad? Researchers at Georgetown University Medical Center say both, and that a balance of APP is critical. http://www.physorg.com/news175105227.html Medicine & Health Sun, 18 Oct 2009 17:21:04 EST news175105227 Neurological diseases including Parkinson's, Tourette's, attention deficit hyperactivity disorder (ADHD), Alzheimer's, and schizophrenia are all associated with alterations in dopamine-driven function involving the dopamine transporter (DAT). Research published today in the open access journal BMC Neuroscience suggests that a number of estrogens acting through their receptors affect the DAT, which may explain trends in timing of women's susceptibility to these diseases. http://www.physorg.com/news164337694.html Medicine & Health Tue, 16 Jun 2009 02:21:48 EST news164337694 Recent studies have shown that the mitochondrial peptide Humanin (HN) protects against neuronal cell death such as happens in Alzheimer's disease. Now, in a study presented April 22 at Experimental Biology 2009 in New Orleans, Dr. Nir Barzilai reports that a small infusion of HN is the most potent regulator of insulin metabolism that his research team has ever seen, significantly improving overall insulin sensitivity and sharply decreasing the glucose levels of diabetic rats. http://www.physorg.com/news159632230.html Biology Wed, 22 Apr 2009 15:17:42 EST news159632230 Brain cells called astrocytes help to cause the urge to sleep that comes with prolonged wakefulness, according to a study in mice, funded by the National Institutes of Health. The cells release adenosine, a chemical known to have sleep-inducing effects that are inhibited by caffeine. http://www.physorg.com/news152375402.html Medicine & Health Wed, 28 Jan 2009 14:30:46 EST news152375402 For the first time, scientists at Children's National Medical Center have successfully identified a key developmental program for the amygdala -the part of the limbic system that impacts how the brain creates emotional memories and responses. http://www.physorg.com/news151055259.html Medicine & Health Tue, 13 Jan 2009 07:47:39 EST news151055259
