The production of a certain kind of brain cell that had been considered an impediment to healing may actually be needed to staunch bleeding and promote repair after a stroke or head trauma, researchers at Duke Medicine report. http://medicalxpress.com/news/2013-04-brain-injury-astrocytes-unexpected-role.html Medical research Wed, 24 Apr 2013 13:00:01 EST news286022977 A team of Korean researchers investigated whether "environmental enrichment" can improve the neurobehavioral function of six week-old mice after transplantation of adipose-derived stem cells (ASCs) to treat hypoxic-ischemic brain injury, and found that brain repair (neurogenesis) was aided in some animals through exercise-induced fibroblast growth factor 2 (FGF2), a strong pro-angiogenic factor. http://medicalxpress.com/news/2013-03-environmental-enrichment-important-factor-impacting.html Medical research Wed, 27 Mar 2013 11:38:43 EST news283603116 Researchers from the University of South Florida and colleagues at the James A. Haley Veterans' Hospital studying the long-term consequences of traumatic brain injury (TBI) using rat models, have found that, overtime, TBI results in progressive brain deterioration characterized by elevated inflammation and suppressed cell regeneration. However, therapeutic intervention, even in the chronic stage of TBI, may still help prevent cell death. http://medicalxpress.com/news/2013-01-long-term-consequences-traumatic-brain-injury.html Neuroscience Fri, 04 Jan 2013 16:51:40 EST news276540691 New research from the University of Georgia identifies the mechanisms responsible for regenerating blood vessels in the brain. http://medicalxpress.com/news/2012-12-treatments.html Medical research Thu, 20 Dec 2012 12:17:49 EST news275228260 Immediate skull reconstruction following trauma that penetrates or creates an indentation in the skull can aggravate brain damage inflicted by the initial injury, a study by a University of South Florida research team reports. Using a rat model for moderate and severe traumatic brain injury, the researchers also showed that a delay of just two days in the surgical repair of skull defects resulted in significantly less brain swelling and damage. http://medicalxpress.com/news/2012-03-skull-resconstruction-immediately-traumatic-brain.html Diseases, Conditions, Syndromes Thu, 22 Mar 2012 09:12:54 EST news251626364 Repeated, low-dose injections of mononuclear cells derived from human umbilical cord blood (MNC hUCB, tradename: U-CORD-CELL) have been found effective in protecting motor neuron cells, delaying disease progression and increasing lifespan for mice modeling amyotrophic lateral sclerosis, or ALS, also referred to as Lou Gehrig's disease, report University of South Florida researchers and colleagues from Saneron CCEL Therapeutics, Inc., and the Ribeirao Preto School of Medicine at the University of Sao Paulo, Brazil. http://medicalxpress.com/news/2012-02-additional-benefits-cord-blood-cells.html Medical research Mon, 06 Feb 2012 09:56:42 EST news247744594 Stroke is a leading cause of long-term disability and death in the United States. A team of researchers — led by Gregory Bix, at Texas A&M College of Medicine, College Station — has identified a way to exploit one of the brain's self-repair mechanisms to protect nerve cells and enhance brain repair in rodent models of stroke. The authors suggest that this approach could provide a nontoxic treatment for stroke. http://medicalxpress.com/news/2011-07-do-it-yourself-brain.html Medical research Mon, 11 Jul 2011 12:47:19 EST news229607231 A study published in the current issue of Cell Transplantation has demonstrated for the first time that endothelial cells derived from cryopreserved human umbilical cord blood cells are phenotypically, as well as structurally and functionally, indistinguishable from freshly isolated endothelial cells. The success of the author's work eliminates the necessity of performing cell isolation procedures prior to their use in clinical transplantation. http://medicalxpress.com/news/2011-05-cryopreserved-endothelial-progenitor-cells-phenotypically.html Medical research Wed, 11 May 2011 15:13:15 EST news224345565
