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 ...

Not just bones: How calcium affects the nervous system and muscles, its connection to chronic stress, and why it’s important ...

Together, these findings suggest that ferulic acid can act as a natural regulator of intestinal motility. By reducing excessive smooth muscle activity, the compound could potentially help calm ...

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 ...

Vitamin D deficiency, rampant in India at 70–90% of the population, adds another layer of trouble by curbing calcium ...

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), ...

Muscle coordination is mostly governed by motor programs built into the nervous system. But one program — the defecation cycle in a worm — has a mechanism that avoids nerves completely and uses ...

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 ...

Calcium is an essential mineral that plays a crucial role in various physiological processes, including bone health, muscle function, nerve transmission, and blood clotting. When calcium levels in the ...

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 ...
