Influenza virus infection is a leading cause of death and disability throughout the world. Influenza-infected hosts are vulnerable to secondary bacterial infection, however, and an ensuing bacterial pneumonia is actually the predominant cause of influenza-attributed deaths during pandemics. A number of mechanisms have been proposed by which influenza may predispose to superinfection with an unr...
neuroleptic malignant syndrome (nms) is a rare fatal medical complication that occurs as a result of dopaminergic receptor blockage in the caudate at the termination of the nigrostriatal pathways (1), and may occur at any time following consumption of dopamine antagonists. this disorder also occurs in cases of sudden discontinuation of dopamine agonists and antagonists (2,3). some studies have ...
A QUANTUM CHEMICAL STUDY OF STRUCTURE -ACTIVITY RELATIONSHIPS OF DIHYDROPYRIDINE CALCIUM ANTAGONISTS
Quantum chemical (MNDo)caleulations have beenused toelucidate the molecular properties and structure - activity relationships of dihydropyridine (DHP) type calcium antagonists. There is a good corielation between the net atomic charges on various atoms of the 4 - phenyl ring of dihydropyridines and pharmacological activity. .Also, activity decreases with increasing free rotation of the phen...
Antimicrobial or host defense peptides are innate immune regulators found in all multicellular organisms. Many of them fold into membrane-bound α-helices and function by causing cell wall disruption in microorganisms. Herein we probe the possibility and functional implications of antimicrobial antagonism mediated by complementary coiled-coil interactions between antimicrobial peptides and de no...
Many common bacterial pathogens utilize quorum sensing to coordinate group behaviors and initiate virulence at high cell densities. The use of small molecules to block quorum sensing provides a means of abrogating pathogenic phenotypes, but many known quorum sensing modulators have limitations, including hydrolytic instability and displaying non-monotonic dose curves (indicative of additional t...
although current guidelines place single leukotriene receptor antagonists use as a therapeutic option in mild persistent asthma, there is still uncertainty about its place. in this study efficiency of montelukast monotherapy in children with moderate persistent asthma was evaluated. children (age 6 to 16) with persistent moderate asthma were treated prospectively with budesonide combined with m...
abstract oculocardiac reflex (ocr) sometimes occurs as a result of pressure on the eye or traction of the intraorbital surrounding structures during ophthalmic surgery. this can result in bradycardiac arrhythmia and cardiac arrest. a 45-year-old female was undergoing an elective squint correction surgery of one eye under local anaesthesia in a private hospital in december 2013. the patient was ...
a case of acute extrapyramidal manifestations consisting of dystonia and akathisia following abrupt discontinuation of propranolol is reported. she responded well to oral propranolol and intramuscular diazepam. extrapyramidal symptoms have commonly been associated with acute or chronic administration of neuroleptic drugs. there have been reports of a substantial number of cases with similar cli...
One hundred and two microorganisms were isolated from 85 paddy soil samples of different locations in Guilan Province. Antagonistic effects of the microorganisms were tested against Gibberella fujikuroi on PDA medium. Twenty one microorganism isolates were selected for seed treatment in blotter test. Seven isolates that were satisfactorily effective in reducing pathogen colonies formed on seeds...
background: gp41 of hiv (human immunodeficiency virus) is a protein that mediates fusion between viral and cellular membranes. the agent, t-20, which has been approved for hiv inhibition, can restrain gp41 function in the fusion process; nevertheless, it has disadvantages like instability, high cost of production and injection form to be delivered twice a day. methods: several molecules like nb...
