University of Minnesota Medical School researchers from the Masonic Cancer Center, University of Minnesota, in partnership with the University's Brain Tumor Program, have developed a new mouse model of malignant peripheral nerve sheath tumors (MPNST) that allow them to discover new genes and gene pathways driving this type of cancer. http://medicalxpress.com/news/2013-05-malignant-peripheral-nerve-sheath-tumors.html Genetics Mon, 20 May 2013 17:41:35 EST news288290452 (Medical Xpress)—One molecule makes nerve cells grow longer. Another one makes them grow branches. These new experimental manipulations have taken researchers a step closer to understanding how nerve cells are repaired at their farthest reaches after injury. The research was recently published in the Journal of Neuroscience. http://medicalxpress.com/news/2013-03-axons-nerve-regeneration-injury.html Neuroscience Fri, 22 Mar 2013 13:10:01 EST news283175564 UT Southwestern Medical Center scientists report the first successful blocking of tumor development in a genetic mouse model of an incurable human cancer. http://medicalxpress.com/news/2013-03-scientists-mouse-human-cancer.html Cancer Tue, 05 Mar 2013 12:16:31 EST news281708184 After four years of confinement to a wheelchair, Rick Constantine, 58, is now walking again after undergoing an unconventional surgery at University of California, San Diego Heath System to restore the use of his leg.

Spinal cord damage is debilitating and life-altering, limiting or preventing movement and feeling for millions worldwide, and leading to chronic health conditions and pain. The new studies suggest potential therapies for managing the aftermath of pain and pressure sores, repairing nervous system damage, and speeding recovery. The findings were presented at Neuroscience 2012, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. http://medicalxpress.com/news/2012-10-recovery-alleviate-pain-spinal-cord.html Neuroscience Mon, 15 Oct 2012 17:10:24 EST news269539511 A study by researchers from Emory University and Indiana University found that the beneficial effects daily exercise can have on the regeneration of nerves also require androgens such as testosterone in both males and females.
