global cerebral ischemia (gci) and reperfusion induced apoptosis that lead to cell injury and death. the bax and bcl-2 are pro-apoptotic and anti-apoptotic genes, respectively. these genes belong to the b-cell lymphoma-2 (bcl-2) family.in this study; we assessed the effect of pentoxifylline drug on bax/bcl2 gene dosage expression changes following   ischemic reperfusion injury in kidney. in thi...

ischemia reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. ischemia reperfusion induces cell death and endemic reaction that is one of the most important clinical problems with acute renal failure and renal transplantation. in this study, the effect of pentoxifylline on rat kidney function and cell injury followi...

conclusions the quite sensitive in-house taqman real time rt-pcr assay was able to detect and quantify all four main hcv genotypes prevailing around all geographical regions of iran. results the lower limit detection of this in-house hcv real-time rt-pcr was determined as 100 rna copies/ml. inter- and intra-assay coefficient of variation (cv) of this in-house hcv real-time rt-pcr ranged from 0....

background: parasitic nematodes cause animal and human diseases of major socio-economic importance worldwide. the suppression of parasite development at particular developmental stages could provide an alternative approach for nema-tode control. in this study, ascaris suum was used as a model system in the study of the differentially expressed genes in the infective l3 stage. methods: the gene ...

background and objective: diarrheal disease is still a major health problem, especially in developing countries, where it is considered as one of the leading causes of morbidity and mortality especially in children. studies showed that diarrheagenic e. coli (dec) such as stes and epec strains are among the most prevalent causative agents in acute diarrhea, particularly in children. aim of the p...

background and objectives: pneumonia with acinetobacter baumannii has a major therapeutic problem in health care settings. decision to initiate correct antibiotic therapy requires rapid identification and quantification of organism. the aim of this study was to develop a rapid and sensitive method for direct detection of a. baumannii from respiratory specimens. materials and methods : a taqman ...

background and objectives : streptococcus pneumoniae is the main causative agent of acute bacterial meningitis in the world. this study aimed to detect pneumoniae infection in cerebrospinal fluid (csf) samples of patients with suspected meningitis. materials and methods : in this study, 200 csf samples in patients with suspected meningitis and with negative bacterial cultures were tested. demog...

background: the effect of curcumin as a natural safe compound with different biological activities was examined on fungal growth and aflatoxin production in aspergillus parasiticus nrrl 2999. methods: the fungus was cultured in presence of serial two-fold concentrations of curcumin (125-2000 µg/ml) in yeast extract sucrose broth for 3 days at 28°c. mycelia dry weight was determined as an index ...
