Researchers in Canada who systematically reviewed data from available relevant studies concluded that wearing helmets reduced the risk of head injury among skiers and snowboarders by 35 per cent with no increased risk of neck injury. You can read about the study conducted by researchers from the Faculty of Medicine at the University of Calgary in Alberta in a paper that was published online in the Canadian Medical Association Journal, CMAJ on 1 February. Skiing and snowboarding are popular winter activities that carry a degree of risk: traumatic brain injury is the leading cause of death and serious injury in this group of sports. Estimates from several countries suggest that 19 per cent of injuries reported by ski patrols and hospital ERs are to the head and 4 per cent are to the neck.
Northwestern University researchers are the first to design a bioactive nanomaterial that promotes the growth of new cartilage in vivo and without the use of expensive growth factors. Minimally invasive, the therapy activates the bone marrow stem cells and produces natural cartilage. No conventional therapy can do this. The results will be published online the week of Feb. 1 by the Proceedings of the National Academy of Sciences (PNAS). "Unlike bone, cartilage does not grow back, and therefore clinical strategies to regenerate this tissue are of great interest, " said Samuel I. Stupp, senior author, Board of Trustees Professor of Chemistry, Materials Science and Engineering, and Medicine, and director of the Institute for BioNanotechnology in Medicine.
