Genetically modified mice: tools to decode the functions of connexins in the heart-new models for cardiovascular research.

abstract：:The response of a simple systolic time interval, the interval between the Q wave and the onset of the aortic blood pressure pulse (the QA interval), to changes in cardiac contractility, cardiac loading, and heart rate was evaluated in anaesthetised open chest dogs. The QA interval was found to be sensitive to increase...

abstract：OBJECTIVE:Numerous studies support the concept of impaired postischemic sympathetic neurotransmission in the heart. We hypothesized that postischemic neuronal dysfunction (neuronal stunning) is caused by a transient suppression of exocytotic norepinephrine (NE) release from sympathetic nerve terminals. Furthermore, we ...
