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 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 ...

Calcium deficiency, once linked to aging, now affects younger adults due to modern lifestyles and poor diets. Early signs ...

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 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 ...

According to research published on NCBI, teeth and bones contain more than 99 percent of total calcium present in a human body. The rest is found in blood, extracellular fluid, muscle, and other ...

TAIPEI (Taiwan News) — Huang Wei (黃薇), a nutritionist at National Cheng Kung University Hospital, said a government health ...

Muscle cramps are a common and often uncomfortable phenomenon that many individuals experience. These sudden, involuntary contractions can occur in various muscle groups, causing sharp pain and ...

IT is believed that muscle contracts or relaxes depending on the concentration of calcium in the sarcoplasm: when the concentration rises to some required level the muscle contracts; when it falls ...
