Calcium ions orchestrate contraction and relaxation in airway smooth muscle by regulating excitation–contraction coupling. In quiescent cells, basal cytosolic Ca2+ is maintained at nanomolar levels by ...

A research group has uncovered important details about how platelet-activating factor (PAF)—a powerful molecule involved in inflammation and allergic reactions—triggers contractions in the smooth ...

A research group led by Dr. Keisuke Obara, Dr. Kento Yoshioka, and Professor Yoshio Tanaka from the Department of Chemical Pharmacology, Faculty of Pharmaceutical Sciences, Toho University, has ...

RUDN University scientists have discovered that in weightlessness, the contractile activity of smooth muscles in the hollow organs of the gastrointestinal tract is disrupted. New data must be taken ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

Electrical muscle stimulation involves sending electrical impulses through the skin. This stimulation may provide benefits, such as helping to repair tissue and strengthen muscles. The electrical ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a University of Michigan study. Nearly all animals use muscle to move, and it's been known for a long ...
