A new molecular pathway has been identified that is critical for maintaining the smooth muscle tone that allows the passage of materials through the digestive system. Researchers at UMass Medical ...

The observations presented herewith seem to demonstrate three distinct, but related facts : formaldehyde, in suitable, small concentrations prevents a sensitized smooth muscle from contracting on ...

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 contractile responses of esophageal smooth muscle (SM) induced by platelet-activating factor (PAF) involve the activation of L-type voltage-dependent calcium channels (L-type VDCCs), ...

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.

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 ...
