The human body contains three kinds of muscle tissue: skeletal, smooth, and cardiac. Only cardiac muscle tissue, comprising cells called myocytes, is present in the heart. In this article ...

A pulled muscle—medically known as a strain—occurs when muscle fibers are stretched too far and sometimes tear. While mild muscle strains can show improvement in as little as three days, severely ...

Second, to study calcium homeostasis in MI/R injury, application and development of new technologies can promote research breakthroughs, such as real-time calcium channel current and calcium ...
