Contractile activity of endothelins and their precursors in human umbilical artery and vein: identification of distinct endothelin-converting enzyme activities.

abstract：:Interventions that inhibit neutrophil infiltration into myocardial tissue after ischaemia and reperfusion are reported to reduce the size of the infarct. We examined whether administration of trimetazidine, which is reported to reduce myocardial infarct size, affects this process. [111In]Neutrophils and [125I]albumin ...

abstract：:A hallmark of vascular disease is the inappropriate proliferative and synthetic behavior of smooth muscle cells. This phenotypically immature behavior arises as a consequence of the myocytes undergoing conversion from a contractile to proliferative/secretory cell type.
