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 ...

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 ...

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— ...

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 ...

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), ...

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 ...
