Background and Objective: Beta-lactamases are the most important factors in the resistance to beta-lactam antibiotics among gram-negative bacteria, especially Klebsiella pneumoniae. Nowadays, the prevalence of infections caused by extended-spectrum β-lactamases (ESBLs)-producing K. pneumoniae is increasing, as one of the emerging health problems throughout the world. This study aimed to investi...
the present study aims at identifying, classifying and analyzing collocation errors made by translators of the holy quran into english.findings indicated that collocationally the most acceptablt translation was done by ivring but the least appropriate one made by pickthall.
background and objectives: klebsiella pneumoniae , one of the important causes of nosocomial infections, is the most common extended spectrum β-lactamases (esbls) producing organism. esbls are defined as the enzymes capable of hydrolyzing oxyimino-cephalosporins, monobactams and carbapenems. the aims of this study were to identify esbl-producing k. pneumoniae isolates and detect their antibioti...
background: multidrug resistance and production of extended spectrum β-lactamases (esbls) by enteric gram-negative rods in hospitals and community continue to be worsened. we aimed to characterize the multidrug resistance and determine the prevalence of esbl production by clinical isolates of enterobacteriaceae in southeast iran. methods: gram-negative bacteria isolated from clinical samples ...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
Objective: The aim of this study was to investigate the trend and how to expand kitchens producing crystal stimulant in cities of Tehran province. Method: The present research was an applied study and in terms of data collection was analytical and descriptive. The statistical population of the study consisted of data related to 42 kitchens producing crystal stimulant discovered in Tehran provin...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
in order to examine the ecological conditions and characteristics of fraxinus excelsior l. in the northern forests of iran 6 main areas as well as some miscellaneous ones , have been selected in the region respectively in : lomir2, shafaroud , park - e-noor , ahlam , alandan and noor.
background: ampc and esbls as mediated-plasmid extended spectrum β-lactabases are the main factors of resistance to extended-spectrum cephalosporins in enterobacteriacea especially e. coli and will follow treatment failure, high costs of treatment in human and economic losses in the poultry industry. objectives: the purpose of this study was to screen and study the faecal e. coli isolates produ...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
