Nearly 20 percent of kidneys that are recovered from deceased donors in the U.S. are refused for transplant due to factors ranging from scarring in small blood vessels of the kidney's filtering units to the organ going too long without blood or oxygen. But, what if instead of being discarded, these organs could be "recycled" to help solve the critical shortage of donor organs? http://medicalxpress.com/news/2013-05-source-kidneys-transplant.html Medical research Mon, 20 May 2013 16:20:04 EST news288284721 A Saudi man who had contracted the coronavirus has died, raising the death toll in the kingdom from the SARS-like virus to 16, the health ministry announced on Monday on its Internet website. http://medicalxpress.com/news/2013-05-sars-like-virus-life-saudi.html Diseases, Conditions, Syndromes Mon, 20 May 2013 16:20:02 EST news288284908 A new "telerehabilitation" approach lets physical therapists assess patients with low back pain (LBP) over the Internet, with good accuracy compared with face-to-face examinations, reports a study in the May 15 issue of Spine. http://medicalxpress.com/news/2013-05-telerehabilitation-accurate-patients-pain.html Diseases, Conditions, Syndromes Mon, 20 May 2013 16:10:01 EST news288284457 Little is known about the effect of physical education (PE) on child weight, but a new study from Cornell University finds that increasing the amount of time that elementary schoolchildren spent in gym class reduces the probability of obesity. http://medicalxpress.com/news/2013-05-gym-class-probability-obesity.html Health Mon, 20 May 2013 16:06:33 EST news288284785 (Medical Xpress)—Individuals who learn two languages at an early age seem to switch back and forth between separate "sound systems" for each language, according to new research conducted at the University of Arizona. http://medicalxpress.com/news/2013-05-bilinguals-languages.html Psychology & Psychiatry Mon, 20 May 2013 16:06:05 EST news288284757 Video games that pit players against human-looking characters may be more likely to provoke violent thoughts and words than games where monstrous creatures are the enemy, according to a new study by researchers at the University of Connecticut and Wake Forest University. http://medicalxpress.com/news/2013-05-human-like-opponents-aggression-video-game.html Psychology & Psychiatry Mon, 20 May 2013 16:04:23 EST news288284652 Hospitals with the highest rates of cardiac arrests tend to have the poorest survival rates for those cases, new University of Michigan Health System research shows. http://medicalxpress.com/news/2013-05-hospitals-cardiac-incidence-survival.html Cardiology Mon, 20 May 2013 16:00:05 EST news288284061 A study by Alexandra L.
