An examination of the ability of inositol 1,4,5-trisphosphate to induce calcium release and tension development in skinned skeletal muscle fibres of frog and crustacea.

abstract：:Endothelial cells play a pivotal role in the development of atherosclerosis. An 'activated' phenotype of these cells is manifested by signal transduction-dependent expression of genes encoding cytokines, pro- and anticoagulant factors, and cell adhesion molecules. In the current study we examined the effect of ouabain...
