Abstract: The smallest contractile unit in striated muscles is the sarcomere. While some of the classic features of contraction assume a uniform behavior of sarcomeres within myofibrils, the occurrence of sarcomere length non-uniformities has been well-recognized… read more here.

Abstract: Heart failure can reflect impaired contractile function at the myofilament level. In healthy hearts, myofilaments become more sensitive to Ca2+ as cells are stretched. This represents a fundamental property of the myocardium that contributes to… read more here.
