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.
Stoker likely drew inspiration from Irish myths of blood-sucking creatures. He was also influenced by Le Fanu's Carmilla. Le Fanu was Stoker's editor when Stoker was a theatre critic in Dublin, Ireland. Like Le Fanu, Stoker created compelling female vampire characters such as Lucy Westenra and the Brides of Dracula.
