In this meta-analysis of diving bradycardia in humans, we sought to quantify any heart rate (HR) reduction using a relatively simple mathematical function. Using the terms "diving reflex,""diving bradycardia,""diving response,""diving plus heart rate," databases were searched. Data from the studies were fitted using HR=c+aexp(-(t-t(0))/τ), where c is the(More)
A series of novel arylpiperazines bearing a pyrrolidin-2-one fragment were synthesized and evaluated for their binding affinity for a 1-and a 2-adrenoceptors (ARs) as well as their antiarrhythmic and antihypertensive activities. The highest affinity for the a 1-AR was displayed by
A series of novel arylpiperazines bearing a pyrrolidin-2-one fragment were synthesized and evaluated for their binding affinity for alpha1- and alpha2-adrenoceptors (ARs) as well as their antiarrhythmic and antihypertensive activities. The highest affinity for the alpha1-AR was displayed by 1-{3-[4-(2-chloro-phenyl)-piperazin-1-yl]-propyl}-pyrrolidin-2-one(More)
Integrating epitaxial and ferromagnetic Europium Oxide (EuO) directly on silicon is a perfect route to enrich silicon nanotechnology with spin filter functionality. To date, the inherent chemical reactivity between EuO and Si has prevented a heteroepitaxial integration without significant contaminations of the interface with Eu silicides and Si oxides. We(More)
