Alzheimer's disease (AD) is a devastating neurodegenerative disorder that causes progressive cognitive impairment and memory loss. Now, a new study published by Cell Press in the September 8 issue of the journal Neuron identifies a previously unrecognized link between neuroinflammation and the classical pathological brain changes that are the hallmark of the disease. In addition, the research identifies a new potential therapeutic target for AD. http://medicalxpress.com/news/2011-09-inflammatory-plaque-formation-alzheimer-disease.html Neuroscience Wed, 07 Sep 2011 13:01:25 EST news234619212 A new target for nitric oxide has been revealed in studies of how it inhibits the growth of Salmonella.

In the July 8th issue of the journal Cell, a Cell Press publication, a new study identifies an enzyme found in glioma stem cells that allows them to grow and seed tumors. Importantly, normal stem cells, including those in the brain, don't appear to share that same dependency. http://medicalxpress.com/news/2011-07-combat-deadly-brain-cancer-stem.html Cancer Thu, 07 Jul 2011 12:54:02 EST news229262008 Scientists from The Scripps Research Institute have identified a surprising new molecular pathway in skin cells that is involved in wound-healing and sensory communication. http://medicalxpress.com/news/2011-06-scientists-molecular-pathway-involved-wound-healing.html Medical research Tue, 28 Jun 2011 17:09:26 EST news228499220 Nitric oxide gas appears to directly impact the source of the classic, disabling pain crises of sickle cell disease, Georgia Health Sciences University researchers report. http://medicalxpress.com/news/2011-05-nitric-oxide-impacts-source-sickle.html Medical research Mon, 09 May 2011 15:55:01 EST news224175262 Exercise both reduces the risk of a heart attack and protects the heart from injury if a heart attack does occur.
