background and objective: the d-test is performed by placing clindamycin and erythromycin impregnated disks at a standard distance on the agar plate then looking for the flattening of inhibition zone around the clindamycin disk. a positive d-test indicates clindamycin inducible resistance and also predicts treatment failure possibility of this antibiotic in clinic. prevalence of staphylococcal ...

Abstract : The variation of the electrical resistivity of a material in the externalmagnetic field is known as magneto resistance. This phenomenon has been attractedboth theoretical and experimental researchers in miniaturization of magneto meters inthe recent years. In this paper, the magneto resistance of an inhomogeneous twodimensional conductor with ladder geometry i...

two barley (hordeun vulgare l.) genotypes, radical and cwb, with good to moderate levels of resistance to powdery mildew were crossed with a highly susceptible cultivar (afzal) to determine the genetics of resistance. the parents, fl, f2 and f3 generations of each of the two crosses, were evaluated for powdery mildew resistance in the glasshouse and field at the college of agriculture in karaj ...

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 ...

the purpose of this study was to evaluate the effect of short time circuit-resistance exercise with difference intensities on ghi/igf-i growth axis in healthy male students. for this purpose, 27 male students with mean and standard deviation of age 21.40±1.78 yr, height 172±0.45 cm, weight 68.85±5.39 kg were selected and randomly divided into three resistance exercise groups (each group, 9 subj...

the house fly, musca domestica l., is known as one of the most important hygiene problems worldwide. it has shown a high potential to develop resistance to chemical insecticides. this study was undertaken to determine the susceptibility or resistance of the house fly, which were collected from 3 livestock farms near the city of ahvaz, to prevalent pyrethroid insecticides (delthamethrin, lambda-...
