a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
background: salmonella enterica serovar typhi, as causative agent of typhoid fever, is one of the most important endemic pathogens. non-typhoidal salmonella serovars, including typhimurium , infantis , and enteritidis are amongst the most prevalent serotypes worldwide and in developing areas such as iran. the aim of this study was to apply a uniplex pcr for rapid detection of salmonella spp., a...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
background and objectives: tuberculosis (tb) is the oldest known bacterial disease in humans. due to the rise of morbidity in recent years, early diagnosis of the disease is necessary. materials and methods: in this study we used fluorescent amplification–based specific hybridization (flash) pcr to target is6110 for rapid detection of m. tuberculosis (mtb). to investigate the important factors ...
a multiplex pcr-based assay was developed for detection of salmonella typhi and identification of other salmonella serotypes. three primer-sets were selected from different genomic sequences, malo2-f/malo2-ra primers from invasion gene, parat-s/parat-as as well as tyv-s/tyv-as primers from o-antigen gene cluster of the genus salmonella. this method differentiated salmonella spp., based on size ...
background: neisseria meninigitidis is one of the most frequently encountered microorganisms associated with central nervous system infections. the aim of this study was to evaluate a pcr-based assay for specific and rapid detection of n. meninigitidis in csf specimens. methods : since april 2002 to july 2006, 130 csf specimens were collected from patients suspected of having bacterial mening...
objectives: salmonella typhimurium is important food-borne pathogen responsible for gastroenteritis. in this work a polymerase chain reaction based enzyme linked immunosorbent assay (pcr-elisa) was developed to identify salmonella typhimurium. materials and methods: the rfb gene which is responsible for biosynthesis of the salmonella o-antigenic lipopolysaccharide was selected as the target s...
Abstract Background and Objectives: Chromogenic media are the newest methods applied for rapid detection of pathogenic microorganisms in drinking water and food from 1998-2008. These Specific media contained the compounds acting as a substrate for microbial enzymes and, according to the type of enzyme, produce specific color. The aim of this study was to introduce the chromogenic media as a pow...
background:accumulative research is in progress to clarify clinical aspects of gbv-c. the possibility of interaction between hcv and gbv-c as well as its consequence on development of liver diseases is the most important clinical aspect which encourages researchers to develop a rapid and cost effective technique for simultaneous detection of both viruses.methods: in this study, a sybr green rea...
abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
