Objective: The Rifampicin resistance and susceptibility of Mycobacterium tuberculosis are caused by mutations in the 81-base pair region of the rpoB gene encoding the b-subunit of RNA polymerase. Methods: Isoniazid resistance of M. tuberculosis is related to mutations in inha , oxyR and ahpC genes which 30 to 90 percent of Isoniazid resistance is occurred in 3015 codons of kat...
Potato virus Y (PVY) is one of the most damaging viruses of potato plants which infecting most cultivars and causing significant yield and economical losses. The application of the concept of pathogen derived resistance opened new horizons for the development of virus-resistant plants. This research was carried out to study RNA silencing to engineered potato plants that are resistant to potato ...
Background and purpose: MicroRNA-122 (miR-122) is the most abundant liver–specific miRNA. It has been reported that miR-122 plays several biological roles such as iron homeostasis, tumor suppressor, hepatic fatty acid regulation, and in hepatocyte differentiation. The Purpose of this study was to investigate changes in liver miR-122 gene expression and serum levels of alanine aminotransferase (...
background and objective: methicillin resistance in staphylococcus aureus is an increasingly important clinical problem. a chromosomal gene, meca, mediates resistance to penicillinase-resistant penicillins such as methicillin and oxacillin in staphylococcus aureus. we evaluated the validity of disk diffusion test by using oxacillin, methicillin and cefoxitin disks with consideration of the pres...
the aim of this study was to determine antibiotic resistance genes, phylogenetic groups and anti-microbial resistance patterns of escherichia coli isolates from fecal samples of healthy pet cats in kerman city. ninety e. coli isolates were recovered from obtained rectal swabs. antibiotic resistance pattern of the isolates against seven selected antibiotic was determined using disc diffusion met...
and people with permanent prostheses. its increased resistance to antibiotics has created a serious challenge for healthcare system. this study was conducted to determine the pattern of antibiotic-resistance of s. epidermidis isolates from clinical samples. methods : during nine months, 251 clinical samples isolated from strains of s. epidermidis were examined. following identification of i...
Background. Omentin-1, a novel adipokine expressed in visceral adipose tissue, is negatively correlated with insulin-resistance and obesity. Objective(s). The aim of this study was to investigate the effect of eight weeks of high-intensity interval training on omentin-1 gene expression in visceral adipose tissue and insulin-resistance in male wistar rats. Methods. A total of 26 male Wis...
Background: Diabetes mellitus is a metabolic abnormality associated with neuropathy, kidney complications, coronary artery disease and peripheral arteries, arteriosclerosis, hypertension and systemic inflammation. The use of high intensity interval training and progressive resistance training to treat metabolic disorders such as diabetes which blood glucose and insulin tolerance has an impor...
Rice bacterial blight caused by Xanthamonos oryzae pv. oryzae is one of the most destructive bacterial diseases of rice in some areas of rice cultivation in the world, especially in the tropics of Asia. The low efficiency of disease management methods, especially chemical methods, has led to more research on recognizing resistant cultivars and understanding resistance mechanisms through the stu...
The aim of this study was to determine antibiotic resistance genes, phylogenetic groups and anti-microbial resistance patterns of Escherichia coli isolates from fecal samples of healthy pet cats in Kerman city. Ninety E. coli isolates were recovered from obtained rectal swabs. Antibiotic resistance pattern of the isolates against seven selected antibiotic was determined using ...
