Researchers were able to control heart muscle function in a new way after discovering the previously unknown role of two enzymes in heart muscle contraction. Although in the early stages, the research ...

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), ...

The ability to modify the intracellular concentrations of divalent calcium ions is vital to normal cell functioning. In the cells of the cardiac muscle, calcium ions play a crucial role in coupling ...

In a new research report, a team of scientists led by Johns Hopkins Medicine say people with severe obesity and a common type ...

IT is well established that an increase in the intracellular concentration of ionized calcium after excitation in the membrane is the key factor for initiation of contraction of various types of ...

The sarcomere is the most basic contractile unit in skeletal and cardiac muscle. Mutations in genes encoding sarcomeric proteins give rise to heritable myopathies, although muscle function is more ...

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 ...

Discover the best calcium supplements, according to dietitians. From capsules, powders, and gummies, find the best choice for ...

Calcium is a key mineral for long-term health, yet many people fall short of their daily needs. In fact, nearly 4 in 10 Americans don’t get enough, which can raise the risk of injury and disease. That ...
