Researchers at UT Southwestern Medical Center at Dallas are the first to use genetically engineered mice containing a fluorescent molecule to examine in real time the chemical reactions that result in ...

The contraction of smooth muscle is an essential process underpinning diverse physiological functions ranging from gastrointestinal motility to vascular regulation. At its core, smooth muscle ...

IT is generally believed that the process which initiates contraction in striated muscle is the depolarization of the excitable membrane of the muscle fibre, although the mechanism by which membrane ...

Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

A new study by researchers at Yale and Johns Hopkins University has discovered how asthmatic bronchial spasms — muscle contractions in the airway that cause difficulty breathing in asthma patients— ...

Researchers describe a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fibre nuclei, and independently of muscle stem cells. Muscle is known to ...

An international team of scientists has provided new insight into the Frank-Starling mechanism, a fundamental aspect of human heart function. An international team of scientists have provided new ...
