Glycogen synthase activation in human skeletal muscle: effects of diet and exercise.

We investigated the role of glycogen synthase in supranormal resynthesis (supercompensation) of skeletal muscle glycogen after exhaustive exercise. Six healthy men exercised 60 min by cycling with one leg at 75% VO2max, recovered 3 days on a low-carbohydrate diet, exercised again, and recovered 4 days on high-carbohydrate diet. Glycogen and glycogen synthase activities at several glucose-6-phosphate (G6P) concentrations were measured in biopsy samples of m.

The sharp dissector as an aid to better surgical procedures.

Various types of bone scrapers, skin scratchers and dissectors have been devised by practitioners. However, in modern operating rooms, a well sharpened general dissector is rarely seen. Experience in doing a wide range of surgical procedures indicated that well crafted dissectors with hollow-ground blades can improve the speed and accuracy of the surgeon as well as reduce the bleeding.
