In recent years, sports hernias have sidelined many high-level athletes for months and, occasionally, prevented a return to competitive sports all together. New research at Washington University School of Medicine in St. Louis shows that surgical repair of sports hernias using tension-free mesh, coupled with an innovative rehabilitation program, successfully returned athletes to competition in 93 percent of cases.

When a strand of DNA breaks in the body's cells, it normally does not take long until it has been repaired. Now researchers at the Swedish medical university Karolinska Institutet have discovered a new mechanism that helps to explain how the cell performs these repairs. The results are presented in Science.

Faulty cell membrane repair causes heart disease

During vigorous exercise, heart muscle cells take a beating. In fact, some of those cells rupture and without an efficient repair process those cells would die and cause heart damage (cardiomyopathy). University of Iowa researchers have discovered a specific repair mechanism in heart muscle and identified a protein called dysferlin that is critical for resealing heart muscle cell membranes.
