Influence of training on myocardial responses of rats subjected to conditions of ischaemia and hypoxia.

abstract：:The second messenger cyclic guanosine 3'5' monophosphate (cGMP) and its downstream effector protein kinase G (PKG) have been discovered more than 40 years ago. In vessels, PKG1 induces smooth muscle relaxation in response to nitric oxide signalling and thus lowers systemic and pulmonary blood pressure. In platelets, P...

abstract：OBJECTIVE:Progressive loss of cardiomyocytes is one of the most important pathogenic characteristics of heart failure. Apoptosis may be an important mode of cell death in heart failure but it must be demonstrated by multiple criteria and not just TUNEL staining alone.
