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 ...

The type 1 ryanodine receptor (RyR1) is an important calcium release channel in skeletal muscles essential for muscle contraction. It mediates calcium release from the sarcoplasmic reticulum, a ...

You get enough electrolytes (charged minerals like sodium, potassium, and calcium) through a balanced diet, but you may ...

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 ...

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 ...

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.
