The contraction of smooth muscle is an essential process underpinning diverse physiological functions ranging from gastrointestinal motility to vascular regulation. At its core, smooth muscle ...

Molecular discoveries may help improve treatments for labor and pain. When labor starts, the uterus must produce steady, precisely timed contractions to allow a safe delivery. Hormones such as ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

A potential new pathway for treating erectile dysfunction that focuses on decreasing contraction of smooth muscles – rather than enhancing their relaxation which is how drugs like Viagra work – has ...

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.

“Our findings highlight key molecular signatures and pathways in contracted muscle [...] that may contribute to skeletal muscle strength loss due to estrogen deficiency.” “Importantly, identification ...

Glucocorticoid steroids improved muscle performance through distinct, sex-specific molecular mechanisms in mice, according to a Northwestern Medicine study published in the Journal of Clinical ...
