The fungal pathogen Candida glabrata has emerged as a major health threat since it readily acquires resistance to multiple drug classes, including triazoles and/or echinocandins. Thus far, cellular mechanisms promoting the emergence of resistance to multiple drug classes have not been described in this organism. Here we demonstrate that a mutator phenotype caused by a mismatch repair defect is ...
introduction: cell culture is a process in which the cells ware isolated from original tissue, dispersed in liquid media and then placed in culture plate where the cells adhere together and propagate. today, this method is used for assessment of cell toxicity, its mechanisms and effect of different compounds on intracellular components. methods: clonogenic assay was used for assessment of cell ...
the toxicity of chlorpyrifos to three iranian populations of two-spotted spider mite, collected from isfahan (isr), yazd (yz) and guilan (gus2) provinces were surveyed using the residual contact vial bioassay. the bioassay results showed that resistance ratios of isr and yz populations were 176.90 and 9.78 fold compared to the gus2 population, respectively. determination of esterase and glutath...
conclusions the results showed that e. coli isolated from patients with uti had eight virulence factors with high frequencies. moreover, these results alleged a direct connection between virulence factors and antimicrobial resistance in e. coli. results the frequency of virulence factors papc, afa, sfa/foc, fimh, hly, neuc, ibea, and iucc were 53.3%, 51.7%, 53.3%, 56.7%, 23.3%, 31.7%, 20%, and ...
در تحقیق حاضر، مطالعه کاملی از آبکاری پالسی آلیاژ طلا ـ کبالت بر روی سوبسترای پوشیده شده با نیکل انجام شد. پارامترهای معین شده در این آبکاری پالسی گالوانو استاتیک شامل ؛ ارتفاع پالس (چگالی جریان)، زمان خاموشی پالس، زمان روشن بودن پالس و دمای حمام بودند که به منظور بدست آوردن یک لایه نانو ساختار مناسب با روش «یک عامل در زمان» بهینه سازی شدند. تاثیر متغیرهای پالسی برروی مورفولوژی، ریزساختار، ترکی...
Contact resistances of bonded copper interconnects in threedimensional integration technology under different bonding conditions are investigated by using a novel test structure. A reduction in specific contact resistance is obtained by longer anneal time. The specific contact resistance of bonded interconnects with longer anneal time does not change with the interconnect sizes. Underlying phys...
The current study evaluated effects of dietary administration doses of Entrococcus faecium on the hematological factors, and disease resistance of Sander lucioperca against Aeromonas hydrophila infection. Fish were fed with dietary administration containing E. faecium doses including of (1010, 108CFU/ g) for diet A1 and A2, respectively in a commercial diet as basal diet were used for 6 weeks. ...
