Researchers develop new system to study trigger of cell death in nervous system (Medical Xpress)—Researchers at the University of Arkansas have developed a new model system to study a receptor protein that controls cell death in both humans and fruit flies, a discovery that could lead to a better understanding of neurodegenerative diseases such as Alzheimer's and Parkinson's. http://medicalxpress.com/news/2013-04-trigger-cell-death-nervous.html Medical research Wed, 03 Apr 2013 15:39:17 EST news284222316 Researchers studying ketamine as suicide prevention drug (Medical Xpress)—University of Alabama at Birmingham (UAB) researchers think ketamine, an anesthesia medication in use since the 1970s, might be a valuable tool in treating severe depression and reducing suicidal urges; they have launched two studies to explore the possibility. One of the studies, ketamine is administered to suicidal patients in the UAB Hospital emergency department (ED), is the only such trial actually being conducted in an ED in the nation. http://medicalxpress.com/news/2013-03-ketamine-suicide-drug.html Psychology & Psychiatry Wed, 27 Mar 2013 09:40:02 EST news283595082 Rewriting a receptor's role: Synaptic molecule works differently than thought (Medical Xpress)—In a pair of new papers, researchers at the University of California, San Diego School of Medicine and the Royal Netherlands Academy of Arts and Sciences upend a long-held view about the basic functioning of a key receptor molecule involved in signaling between neurons, and describe how a compound linked to Alzheimer's disease impacts that receptor and weakens synaptic connections between brain cells. http://medicalxpress.com/news/2013-02-rewriting-receptor-role-synaptic-molecule.html Alzheimer's disease & dementia Tue, 19 Feb 2013 13:44:20 EST news280503847 Scientists learn more about how inhibitory brain cells get excited Scientists have found an early step in how the brain's inhibitory cells get excited. http://medicalxpress.com/news/2013-01-scientists-inhibitory-brain-cells.html Neuroscience Wed, 30 Jan 2013 13:16:39 EST news278774191 Experimental agent briefly eases depression rapidly in test: Works in brain like ketamine, with fewer side effects (Medical Xpress)—A drug that works through the same brain mechanism as the fast-acting antidepressant ketamine briefly improved treatment-resistant patients' depression symptoms in minutes, with minimal untoward side effects, in a clinical trial conducted by the National Institutes of Health. The experimental agent, called AZD6765, acts through the brain's glutamate chemical messenger system. http://medicalxpress.com/news/2012-12-experimental-agent-briefly-eases-depression.html Psychology & Psychiatry Tue, 11 Dec 2012 08:19:31 EST news274436364 Drug fights hard-to-treat depression by targeting brain receptors in a new way A first-of-its-kind antidepressant drug discovered by a Northwestern University professor and now tested on adults who have failed other antidepressant therapies has been shown to alleviate symptoms within hours, have good safety and produce positive effects that last for about seven days from a single dose.  http://medicalxpress.com/news/2012-12-drug-hard-to-treat-depression-brain-receptors.html Medical research Fri, 07 Dec 2012 09:50:01 EST news274095217 Unique protein bond enables learning and memory Two proteins have a unique bond that enables brain receptors essential to learning and memory to not only get and stay where they're needed, but to be hauled off when they aren't, researchers say. http://medicalxpress.com/news/2012-10-unique-protein-bond-enables-memory.html Medical research Tue, 30 Oct 2012 17:46:30 EST news270837961 Overcoming memories that trigger cocaine relapse Researchers from the University of Wisconsin-Milwaukee (UWM) have identified mechanisms in the brain responsible for regulating cocaine-seeking behavior, providing an avenue for drug development that could greatly reduce the high relapse rate in cocaine addiction. http://medicalxpress.com/news/2012-10-memories-trigger-cocaine-relapse.html Neuroscience Wed, 17 Oct 2012 09:41:23 EST news269685673 Early treatment improves outcomes in rare, often undiagnosed form of encephalitis A mysterious, difficult-to-diagnose, and potentially deadly disease that was only recently discovered can be controlled most effectively if treatment is started within the first month that symptoms occur, according to a new report by researchers from the Perelman School of Medicine at the University of Pennsylvania. http://medicalxpress.com/news/2012-04-early-treatment-outcomes-rare-undiagnosed.html Diseases, Conditions, Syndromes Fri, 20 Apr 2012 10:55:32 EST news254137430 New drug target for Alzheimer's, stroke discovered A tiny piece of a critical receptor that fuels the brain and without which sentient beings cannot live has been discovered by University at Buffalo scientists as a promising new drug target for Alzheimer's and other neurodegenerative diseases. http://medicalxpress.com/news/2011-10-drug-alzheimer.html Alzheimer's disease & dementia Tue, 11 Oct 2011 12:00:53 EST news237553223 Experience puts the personal stamp on a place in memory Seeing and exploring both are necessary for stability in a person's episodic memory when taking in a new experience, say University of Oregon researchers. http://medicalxpress.com/news/2011-08-personal-memory.html Neuroscience Mon, 22 Aug 2011 15:28:06 EST news233245674
