But this may be about to change: Christian Peham and colleagues at the University of Veterinary Medicine, Vienna have undertaken a detailed analysis of the three most important ligaments in the ankle. The group investigated the ligaments' movements and the strains to which they are subjected during the jump shot, the most frequent shot at goal. Peham's study is published in the Journal of Biomechanics. http://medicalxpress.com/news/2012-01-pain-gain-ideal-shots-handball.html Other Tue, 10 Jan 2012 10:30:51 EST news245413846 Scientists at the University of Gothenburg, Sweden, have used advanced light microscopy to show that a substance can be differently absorbed by the skin, depending on what it is mixed with.

Because the immune system cannot know what to expect, it must be prepared to fend off virtually any foreign pathogen it might encounter. Now, Howard Hughes Medical Institute scientists have identified a genetic regulator that controls the reshuffling of gene segments that immune cells use to manufacture billions of distinct antibodies and pathogen-recognizing receptors from a limited number of genes. http://medicalxpress.com/news/2011-09-genetic-immune-diverse-threats.html Genetics Sun, 11 Sep 2011 13:59:30 EST news234968361 Researchers have built the first functional anal sphincters in the laboratory, suggesting a potential future treatment for both fecal and urinary incontinence.
