About 80% of the active population suffers from low back pain at some point in their lives. In a paper published on August 4th 2011 in PLoS Computational Biology, researchers at the Institute for Bioengineering of Catalonia (IBEC) show that overloading on already degenerated discs is less damaging than on discs which are still healthy – and that changes in cell density in discs are fundamental to the process of disc degeneration. http://medicalxpress.com/news/2011-08-spinal-disc-degeneration.html Other Thu, 04 Aug 2011 17:00:01 EST news231690812 Researchers at Stanford University School of Medicine have been able to switch on, and then switch off, social-behavior deficits in mice that resemble those seen in people with autism and schizophrenia, thanks to a technology that allows scientists to precisely manipulate nerve activity in the brain. In synchrony with this experimentally induced socially aberrant behavior, the mice exhibited a brain-wave pattern called gamma oscillation that has been associated with autism and schizophrenia in humans, the researchers say. http://medicalxpress.com/news/2011-07-social-deficits-autism-schizophrenia-mice.html Medical research Wed, 27 Jul 2011 13:30:26 EST news230992205 Bioengineers at Harvard have identified, for the very first time, the mechanism for diffuse axonal injury and explained why cerebral vasospasm is more common in blast-induced brain injuries than in brain injuries typically suffered by civilians. http://medicalxpress.com/news/2011-07-bioengineers-cellular-mechanisms-traumatic-brain.html Medical research Sat, 23 Jul 2011 04:05:39 EST news230612707 Rice University bioengineering students have modified a child-size training mannequin to give medical students hands-on pediatric experience so that real patients can be spared further stress and pain. http://medicalxpress.com/news/2011-05-child-size-mannequin-hands-on-real-patients.html Other Mon, 16 May 2011 16:39:28 EST news224782717
