objectives: to investigate fasting glucose, glucose tolerance, insulin resistance and insulin–like growth factor 1 in patients with or without colorectal polyps. materials and methods: in this cross-sectional study, we evaluated fasting glucose, insulin, insulin–like growth factor 1 (igf-1), lipid profile and glucose tolerance test in 103 patients undergoing colonoscopy (52 normal and 53 with a...
there is a growing concern about the application of molecular methods in epidemiological studies of infectious diseases. the objective of this study was to determine the genetic stability of methicillin resistance genes in staphylococcus aureus for the evaluation of resistance strain distribution. one hundred and fifteen s. aureus isolates from patients with staphylococcal infection were collec...
results a total of 18 amoxicillin-clavulanate resistant isolates were obtained from seven different types of retail sausages. only half of them were identified as enterobacteriaceae, but none were esbl-producers. all the 18 isolated strains demonstrated resistance towards amoxicillin-clavulanate, penicillin and oxacillin (100%), cefotaxime (71.4%), cefpodoxime (66.7%), and ampicillin (83.3%). b...
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 Background and Objective: Resistance to antiretroviral agents is a significant concern in clinical management of HIV-infected individuals. Resistance is the result of mutations that develops in the viral protein targeted by antiretroviral agents. Material and Methods: In this cross-sectional study, the blood samples of 40 HIV-positive patients were collected. Twenty of them were d...
Abstract Bachground and Objective: most of environmental microorganisms have the genes resistance to antibiotics and metals. The aim of the current study was to survey resistance pattern to some antibiotics and heavy metals in three pseudomonas aeruginosa isolated from different ecological areas. Material and Methods: first, the isolates were identified by biochemical methods and phylogenetic a...
Introduction:Obesity is one of the most important risk factors for non-communicable diseases. One treatment in this context is the use of resistance exercise and green tea. The aim of this study was to investigate the effects of resistance training and green tea supplementation on lipid profile and insulin resistance in obese and overweight men. Methods: In this clinical trial, 60 men with a...
Background and Objectives: Osteocalcin plays an important role in stimulating of insulin secretion from pancreatic β-cells. Therefore, the present study aimed to determine the effect of aerobic and resistance exercises on serum osteocalcin, insullin resistance and beta cells function in overweight men. Materials and Methods: In this clinical trial study conducted in Ahar in summer 2018, 40 ove...
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 ...
