Smooth muscle contraction bands (SMCBs) have been described in the gastrointestinal tract, subsequent to acute ischemia, and in the coronary arteries of animals and individuals with a sudden death ; in these circumstances SMCBs have been postulated to serve as a premortem marker, and suggested ...
Smooth muscle contraction occurs via a sliding filament mechanism similar to that in striated muscles. The contractile apparatus of smooth muscle consists of the contractile proteins—actin/tropomyosin and myosin that are organized into thin and thick filaments, respectively—and associated regulatory protei...

(EPA), an omega-3 polyunsaturated fatty acid (n-3 PUFA), effectively inhibits sphingosylphosphorylcholine (SPC)-induced Ca2+-sensitization of vascular smooth muscle (VSM) contraction which is a major cause of cardiovascular and cerebrovascular vasospasm, and EPA is utilized clinically to prevent ...

Major factors affecting arteriolar radius Capillaries(毛细血管) Main function: Exchange of nutrients and metabolic end products Capillaries lack smooth muscle, but contraction/relaxation of circular smooth muscle in upstream metarterioles and precapillary sphincters determine the volume of blood each ...
We previously reported that eicosapentaenoic acid (EPA), an omega-3 polyunsaturated fatty acid (n-3 PUFA), effectively inhibits sphingosylphosphorylcholine (SPC)-induced Ca2+-sensitization of vascular smooth muscle (VSM) contraction which is a major caus
