zoanthamine-type alkaloids display a wide spectrum of biological effects. this study aimed to examine the inhibitory effects of norzoanthamine and its ten homologues of zoanthamine class on human fibroblast collagenase by modeling a three-dimensional structure of the ligands at collagenase using energy minimization, docking, molecular dynamics simulation and mm-pb/gbsa binding free energy calcu...
background: in order to obtain an anti-cd20 conjugate to be used in future therapeutic studies with therapeutic radioisotopes, 67ga-labeled antibody was prepared as a model of metal chelated immunoconjugate for preliminary dosimetric and biodistribution studies. materials and methods: rituximab was labeled with [67ga]-gallium chloride after residulation with freshly prepared cyclic dtpadianhydr...
carbapenemase producing bacteria frequently possess resistance mechanisms to a wide-range of antibacterial agents, and are associated with high mortality and morbidity rates. some enzymes like extended-spectrum β-lactamase (esbl), new delhi metallo-beta-lactamase-1 (ndm-1), klebsiella pneumoniae carbapenemase (kpc), and oxa-producing enterobacteriaceae are very important in frequently isolated ...
results ll-37 and its truncated analogs were effective in inhibiting the growth of pdrab and had a rapid killing ability. after exposure to the peptides, the development of the pdrab biofilm was inhibited. strong inhibitory and dispersion effects of ff/cap18 on the biofilm were confirmed by fluorescence microscopy and field emission scanning electron microscopy. conclusions this results show th...
فرض کنید a و b ، -c^*جبر باشند و x یک باناخ a-دومدول اساسی باشد و همچنین t:a→b و s:a→x نگاشت های خطی پیوسته باشند که t پوشا است. اگر برای هر a,b∈a a که ab=ba=0 داشته باشیم t(a)t(b)+t(b)t(a)=0, s(a)b+bs(a)+as(b)+s(b)a=0 مطالعه می کنیم که t=ωφ و s=d+? هستند که w در مرکز جبر ضربگر b قرار دارد و ∅:a→b بروریختی جردن می باشد و d:a→x مشتق ...
background: this study aimed to evaluate the role of efflux pump regulator and oxa-23 genes in imipenem resistance acinetobacter baumannii strains isolated from hospitalized patients in tehran, iran. methods: this study was conducted on 60 a. baumannii isolates collected from patients admitted to the shahid motahari and taleghani hospitals in tehran during 2013-14. antibiotic susceptibility tes...
background :adenosine is an endogenous purine nucleoside that has a neuromodulatory role in the central nervous system. the amphetamine derivative (±)-3,4-methylenedioxymethamphetamine (mdma or ecstasy) is a synthetic amphetamine analogue used recreationally to obtain an enhanced affiliated emotional response. mdma is a potent monoaminergic neurotoxin with the potential of damage to brain neuro...
conclusions more than behalf of the wound isolates were esbl positive, and the presence of blaveb-1 was determined in less than half of these isolates. fortunately, resistance to imipenem and meropenem was low. results the majority of the wound isolates were resistant to augmentin (90%, n = 80) and cefpodoxime (87.6%, n = 78). however, the majority was susceptible to imipenem and meropenem. fif...
a new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. the synthesised compounds have been screened in vitro for their antimicrobial acti...
normal 0 false false false en-us x-none ar-sa approximately 1% of all pregnancies are in woman with epilepsy. although, the majority of children born to women with epilepsy are normal, they are at increased risk for malformations. notably, the teratogenicity of antiepileptic drugs is a well-defined subject. the incidence of major malformations in offspring of mothers with epilepsy who were trea...
