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 ...

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 ...

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.

Ferulic acid suppresses ileal smooth muscle contraction by inhibiting calcium ion influx through voltage-dependent calcium channels. This action may help prevent or treat excessive intestinal motility ...

DALLAS – April 5, 2004 – 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 ...

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

Panel A shows the microscopic myoarchitecture of the circular and longitudinal muscle layers of the lower esophageal sphincter and stomach. The circular muscle fibers of the esophagus cross each other ...

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 ...

A research group has discovered that certain naturally occurring peptides in the body can trigger contractions in the vas deferens—a muscular tube that carries sperm in the male reproductive system.
