The mechanism of skeletal muscle contraction is a process that relies on calcium signaling. However, the physiological role of calcium-induced calcium release (CICR) through the ryanodine receptor ...

A research team at Toho University has revealed that ferulic acid (FA), a polyphenol abundant in rice bran, suppresses intestinal smooth muscle contractions by inhibiting voltage-dependent calcium ...

Discover ten surprising sources of calcium beyond dairy, including how much each food contains and simple ways to add them to ...

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 ...

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release. The ...

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.

The muscle damage that will weaken you at 60 may begin decades earlier. Not as soreness or fatigue, but as a microscopic cascade you cannot feel: damaged proteins piling up, calcium pumps seizing, the ...

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 ...
