Although the protein, called TRAP-alpha, was first discovered more than 30 years ago, its biological function has been unclear. The new findings, reported Dec. 4 in Science Advances, demonstrate that TRAP-alpha is required for both early and late steps in insulin synthesis.
Cardiac valve surgery patients who participate in a cardiac rehabilitation program have a 34% lower risk of hospitalizations and a 4.2% lower risk of mortality than patients who do not enroll in cardiac rehab in the year after surgery.
