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. It is the first report of both androgen-dependence of exercise on nerve regeneration and of an androgenic effect of exercise in females. http://medicalxpress.com/news/2012-10-role-androgens-testosterone-nerve.html Neuroscience Mon, 15 Oct 2012 12:00:03 EST news269499339 Using tiny spheres filled with an anesthetic derived from a shellfish toxin, researchers at Boston Children's Hospital and the Massachusetts Institute of Technology have developed a way to delay the rise of neuropathic pain, a chronic form of pain that arises from flawed signals transmitted by damaged nerves. http://medicalxpress.com/news/2012-10-block-neuropathic-pain.html Medical research Tue, 09 Oct 2012 10:52:28 EST news268998715 Modulating immune response to injury could accelerate the regeneration of severed peripheral nerves, a new study in an animal model has found. By altering activity of the macrophage cells that respond to injuries, researchers dramatically increased the rate at which nerve processes regrew. http://medicalxpress.com/news/2012-10-immune-boost-regeneration-peripheral-nerves.html Medical research Tue, 02 Oct 2012 11:00:35 EST news268394418 When a motor nerve is severely damaged, people rarely recover full muscle strength and function. Neuroscientists from Children's Hospital Boston, combining patient data with observations in a mouse model, now show why. It's not that motor nerve fibers don't regrow -- they can -- but they don't grow fast enough. By the time they get to the muscle fibers, they can no longer communicate with them. http://medicalxpress.com/news/2011-10-reversing-motor-nerve-essence.html Medical research Mon, 03 Oct 2011 12:00:05 EST news236861754 A common technique for determining whether melanoma has spread can be used safely and effectively even in tumors from the head and neck area, according to a new study from the University of Michigan Comprehensive Cancer Center. http://medicalxpress.com/news/2011-08-sentinel-node-biopsy-safe-effective.html Cancer Fri, 05 Aug 2011 11:01:44 EST news231760879 Drugs already in development to treat Alzheimer's disease may eventually be tapped for a different purpose altogether: re-growing the ends of injured nerves to relieve pain and paralysis. According to a new Johns Hopkins study, experimental compounds originally designed to combat a protein that builds up in Alzheimer's-addled brains appear to make crushed or cut nerve endings grow back significantly faster, a potential boon for those who suffer from neuropathies or traumatic injuries. http://medicalxpress.com/news/2011-04-experimental-alzheimer-disease-drugs-patients.html Neuroscience Wed, 13 Apr 2011 14:34:11 EST news221924004
