alpha-, beta 1- and beta 2-adrenergic receptors in the kidney mediate vasoconstriction, renin secretion and vasodilatation, respectively. Blockade of beta-receptors may therefore be expected to influence renal blood flow and possibly glomerular filtration rate by intrarenal effects as well as by reducing cardiac output and blood pressure.
Vampires proper originate in folklore widely reported from Eastern Europe in the late 17th and 18th centuries. These tales formed the basis of the vampire legend that later entered Germany and England, where they were subsequently embellished and popularized.ccording to the paper, if the first vampire had appeared on 1 January 1600, and it fed once a month (which is less often than what is depicted in films and folklore), and every victim turned into a vampire, then within two and a half years the entire human population of the time would have become vampires.
Dracula is often referred to as the definitive vampire novel, but it is possible that Stoker was influenced by Joseph Sheridan LeFanu's (1814-1873) Gothic vampire novella Carmilla (1872). While Stoker wrote numerous novels and short stories, he is chiefly remembered today as the author of this best-selling novel.
