Inclusions in aged mitochondria.

abstract：:Recent studies of isolated muscle membrane have enabled induction and monitoring of rapid Ca2+ release from sarcoplasmic reticulum (SR)5 in vitro by a variety of methods. On the other hand, various proteins that may be directly or indirectly involved in the Ca2+ release mechanism have begun to be unveiled. In this min...
