Due to the genetic mutation (fa) in gene encoding for leptin receptor, homozygous Zucker rats (fa−/−) develop excessive adiposity and become an experimental animal model obesity metabolic-related diseases research. Based on tetra-primer amplification refractory system-polymerase chain reaction (ARMS-PCR), we developed a method quickly genotype with mutated fa allele from their wildtype litterma...

Objectives. Chemotherapy is considered to be essential in the treatment of patients with colorectal cancer (CRC), but drug resistance reduces its efficacy. Many advanced CRC eventually show 5-fluorouracil (5-FU) therapy. Synergistic and potentiating effects combination therapy, using herbal chemical drugs, can improve patients’ response. Zerumbone (ZER), which derived from ginger, has been stud...

Insulin-like growth factor 1 (IGF-1) is a polypeptide hormone produced mainly by the liver in response to the endocrine growth hormone (GH) stimulus. This protein is involved in a wide range of cellular functions, including cellular differentiation, transformation, apoptosis suppression, migration and cell-cycle progression and other metabolic processes. In the current study, human heart cDNA w...

The identification of a new murine pathogen, Helicobacter hepaticus, and its association with chronic active hepatitis and liver tumors prompted an evaluation of the prevalence of H. hepaticus in commercially available mice. Of the 28 different strains or stocks, totaling 160 mice from four major commercial vendors, cultured for H. hepaticus, 100% of mice from two outbred strains from one vendo...

abstract: in order to determine genetic variability among 33 isolates of fusarium semitectum, morpho- logical and molecular studies were carried out. isolates from different paddy fields in the north of iran were separated from each other in four morphotype groups. the isolates showed a high level of variation in aerial mycelium, color of colony, number of septa and growth rate on potato dextro...

Abstract Background Recent studies have established the roles of microRNAs (miRNAs) in cancer progression. The aberrant expression miR-335-5p has been reported many cancers, including gastric (GC). In this study, precise GC as well molecular mechanisms underlying its effects, role target MAPK10, were evaluated. Methods Quantitative real-time PCR was used to evaluate levels cell lines and tissue...

To evaluate different methods for their abilities to detect methicillin resistance in small-colony variants (SCVs) of Staphylococcus aureus, 11 different methicillin-resistant S. aureus (MRSA) clones with the SCV phenotype were used in this study. The slow growth of SCVs often makes testing by disk diffusion or by automated methods invalid. Only detection of the mecA gene by PCR and the MRSA-Sc...

We describe here the PCR amplification of a DNA fragment (mtp1) from Mycobacterium smegmatis using primers derived from consensus sequences of the ABC family of transporters. The fragment encodes amino acid sequences that exhibited significant homology with different ABC transporters. Amino acid sequence alignment of the full length gene with other transporters identified the ABC protein as the...

Fifty-five isolates of Escherichia coli from septicaemic neonatal foals were used to validate five real-time pcr assays targeting different known virulence factor genes: curli fibre (csgD), ferric hydroxamate uptake (fhuA), type 1A pilin (fimA), aerobactin (lutA) and yersiniabactin (fyuA). A pcr assay targeting a universal sequence of the bacterial 16S rrna gene served as quality control. The p...
