among the 30 strains of moderately halophilic bacteria isolated from the salty effluents of textile industries around qom city in central iran, a gram-negative rod shape bacterium designated as strain ip8 showed a remarkable ability in decolorizing of azo dyes over wide ranges of ph (7-11) and temperature (25-45 ºc), in presence of nacl and na2so4 (0.5-1.5 m) under anaerobic and aerobic conditi...

objective : the aim of study was to develop a rapid assay, dye labelled monoclonal antibody assay (dlmaa), using non-radioactive organic synthetic dyes for identification of toxic shock syndrome toxin-1 (tsst-1) producing strains of staphylococcus aureus. materials and methods: the assay protocol required only two simple steps; addition of tsst-1 antigen to a nitrocellulose membrane and then ad...

background and objectives: secreted aspartyl proteinase (sap) is one of the main virulence factors in the pathogenesis of candida. this enzyme is encoded by a family of at least ten genes. among these genes, the role of sap1-3 in mucosal infections is evident. this study aimed to investigate the expression of sap1-3 genes of candida albicans isolates after treatmentwith echinophora platyloba ex...

the abscission of alstroemeria petals is the serious problem at the industry of cut flowers of this plant. in this study, cut alstroemeria cv. bridal flowers were pulsed with solutions containing natural essential oil carvacrol, gibberellic acid and benzyladenine (50 and 100 mg l-1), -5-sulfosalicylic acid (1 and 1.5 mm) and sucrose (5 and 10%) for 24 hours. the distilled water was used as cont...

objective(s): although low-dose radiotherapy (rt) that involves low collateral damage is more suitable for hepatocellular carcinoma (hcc) than traditional high-dose rt, but to achieve satisfactory therapeutic effect with low-dose rt, it is necessary to sensitize hcc cells to irradiation. this study was aimed to determine whether radiosensitivity of hcc cells can be enhanced using mir-26b by tar...

background: human cripto-1, a member of the egf-cfc family, is involved in embryonic development, embryonic stem cell maintenance, and tumor progression. it also participates in multiple cell signaling pathways including wnt, notch, and tgf-β. remarkably, it is expressed in cancer stem cell (csc) compartments, boosting tumor cell migration, invasion, and angiogenesis. although cripto-1 is overe...

endothelial dysfunction is thought to be a central pathogenic feature in preeclampsia on the basis of elevated adhesion molecules. soluble forms of these molecules can be detected in plasma, and their concentrations are thought to reflect the degree of activation of a particular cell type. the aim of the present study was to compare the levels of soluble vascular cell adhesion molecule-1 (svcam...

the activity of one of the metabolizing enzymes of - aminobutyric acid, (gaba), was determined in mouse hypothalamus after peripheral injections of cholecystokinin-8 (cck-8) and caerulein (cln). the activity of this rate-limiting enzyme, l-glutamic acid decarboxylase, (gad), did not change thirty minutes after peripheral injections of either cck-8 or cln in doses of 50g/kg body weight. howeve...
