Researchers discovered that small pieces of genetic material called microRNAs link the two defining characteristics of fit muscles: the ability to burn sugar and fat and the ability to switch between slow- and fast-twitch muscle fibers. The team used two complementary mouse models—the "marathon mouse" and the "couch potato mouse"—to make this discovery. But what's more, they also found that active people have higher levels of one of these microRNAs than sedentary people. These findings, published May 8 in The Journal of Clinical Investigation, suggest microRNAs could be targeted for the development of new medical interventions aimed at improving muscle fitness in people with chronic illness or injury. http://medicalxpress.com/news/2013-05-differences-marathon-mice-couch-potato.html Medical research Wed, 08 May 2013 11:03:06 EST news287229778 Ninety-eight percent of women undergoing breast augmentation surgery say the results met or exceeded their expectations, according to a prospective outcome study published in the May issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS). http://medicalxpress.com/news/2013-05-breast-augmentation-patients-high-satisfaction.html Surgery Wed, 01 May 2013 12:27:29 EST news286630041 (Medical Xpress)—Robots are everywhere these days.

However, in a small number of children, symptoms can last for a month or more. Although there have been numerous theories as to what might predict a longer recovery time, there is no definitive answer as to why it takes some children longer to recover. In a new study scheduled for publication in The Journal of Pediatrics, researchers attempted to identify risk factors that might predispose some children with concussions to longer recovery times. http://medicalxpress.com/news/2013-04-severe-concussion-symptoms-longer-recovery.html Pediatrics Thu, 25 Apr 2013 00:00:03 EST news286045274 Good news for anyone needing a transplant; a new Mayo Clinic survey shows that the public's support for both living and deceased organ donation is increasing.
