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), ...

DHA has previously been shown to inhibit voltage-dependent Ca 2+ channels (VDCCs). The research group found a new pharmacological action of DHA to inhibit the Orai1 channel, which is one of ...

Molecular discoveries may help improve treatments for labor and pain. When labor starts, the uterus must produce steady, ...

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 ...

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.

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 ...

Duchenne muscular dystrophy (DMD) causes dysfunction of muscle cells that help move blood through the circulatory system, a study found. The changes associated with DMD included dysregulated activity ...

Contractions are when the muscles of your uterus tighten and relax to get ready for childbirth. These muscles help push your baby down the birth canal. Once you reach week 37 of your pregnancy, it ...
