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 ...

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 ...

Together, these findings suggest that ferulic acid can act as a natural regulator of intestinal motility. By reducing excessive smooth muscle activity, the compound could potentially help calm ...

The molecular regulation of smooth-muscle contraction is an important determinant of airway responses during an acute asthmatic attack. In acute asthma, various triggers, including viral illnesses and ...

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 ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

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 ...
