Study of the nonselective serotonergic agonists fenfluramine and dexfenfluramine, which enhance presynaptic serotonin launch and block its reuptake, validated serotonin receptors as pharmacologic targets for weight loss.4 Unfortunately, usage of these agents escalates the threat of serotonin-associated valvulopathy,5-8 that is thought to happen through agonism of 5-HT2B receptors expressed on cardiac valvular interstitial cells.9-11 Lorcaserin was made to activate central 5-HT2C receptors selectively, with a functional selectivity of approximately 15 times that for 5-HT2A receptors and 100 times that for 5-HT2B receptors.12,13 In a 12-week clinical trial involving obese patients, the usage of lorcaserin was connected with dose-dependent weight loss without apparent results on heart valves.14 Today’s report describes the Behavioral Modification and Lorcaserin for Overweight and Obesity Management trial, a 2-year, randomized, placebo-controlled, double-blind clinical trial made to evaluate the efficacy and safety, including safety relating to cardiac valves, of lorcaserin used for weight management.Al-Ibrahim, M.B., Ch.B., Wilbur H.

Mendelman, M.D.: Norovirus Vaccine against Experimental Human being Norwalk Virus Illness Noroviruses are a leading cause of epidemic acute gastroenteritis and so are also an important reason behind sporadic instances of acute gastroenteritis.1 Because individual noroviruses have not been grown in cell culture and there are no convenient animal models in which to evaluate immunity and illness, much of our knowledge about these viruses comes from the study of outbreaks and experimental human being infection. Norwalk virus , the prototype individual norovirus, caused a school-based outbreak of epidemic gastroenteritis in 1968,2 in fact it is the most studied individual norovirus extensively.3-5 Susceptibility to Norwalk virus infection would depend on expression of an operating fucosyltransferase 2 gene; persons who’ve a nonfunctional FUT2 gene are resistant to Norwalk virus infection genetically.6,7 The FUT2 gene is involved in expression of the histo-blood group antigen H type 1 on the surface of epithelium.
