Study on source rock features and resources evaluation of Yishu graben;

Lying in the east of Heilongjiang province, Yishu graben is a Cenozoic fault basin comprising two large second-class structural units, i.

Objective To investigate the effects of perfusion pressure with a cardioplegic solution on endothelium-dependent relaxation and smooth muscle function of porcine coronary artery.

Methods Endothelium-dependent relaxation responses to acetylcholine (ACh) of thoracic aortic rings were measured by isometric tension recording before and after aortic rings exposed to Hcy in the absence or presence of pravastatin (PT) to estimate the injury effect of Hcy and the protective effect of pravatatin on rabbit aortic endothelium, respectively.

Carotid intima-media thickness, integrated backscatter and brachial artery endothelial dependent vasodilation in diagnosis of coronary artery diseases;
