Aging is the main risk factor for coronary artery disease. One characteristic of aging coronary arteries is their enhanced contractile responses to endothelial vasoconstricting factors, which increase the risk of coronary vasospasm in older people. Because large-conductance voltageand Ca-activated K channels (MaxiK) are key regulators of vascular tone, we explored the possibility that this clas...

Accurate and meaningful measurements of blood pressure (BP) are often critical to the interpretation of studies of vascular biology, atherosclerosis, and other forms of cardiovascular disease. Although many research scientists have embraced advanced molecular technologies for studying cardiovascular function and disease pathogenesis, a surprising number of the same investigators continue to use...
There is one disturbing similarity between the two very dissimilar hospitals. In both cases industrial relations have been complicated and embittered by a degree of interunion competition that seems to have left management virtually powerless to effect improvements in the departments and sections concerned. _011|Rainhill is a 1550-bedded psychiatric hospital in the St Helens and Knowsley AHA, m...
This study proposes an artificial hummingbird algorithm (AHA) for energy management (EM) optimal operation of a microgrid (MG), including conventional sources and renewable (RES), with incentive-based demand response (DR). Due to the stochastic nature solar wind output power uncertainty prices load, probabilistic EM hybrid AHA point estimation method (PEM) is proposed model this by utilizing no...
BACKGROUND The American Heart Association (AHA) guidelines for cardiopulmonary resuscitation (CPR) are nowadays recognized as the world's most authoritative resuscitation guidelines. Adherence to these guidelines optimizes the management of critically ill patients and increases their chances of survival after cardiac arrest. Despite their availability, suboptimal quality of CPR is still common....
As noted in my Presidential Address at the 70th Scientific Sessions of the American Heart Association, cardiovascular disease and stroke remain the No. 1 and No. 3 causes of death, respectively, of all Americans. This is due in part to a gap that exists between effective interventions in clinical trials to improve patient care and outcomes and daily practice of healthcare professionals as well ...
