sulfur mustard (sm) has been identified as an important chemical weapon. during the iran-iraq war of 1980-88, the extensive usage of sm against iranian civilians and military forces was proven. this agent has been shown to cause severe damage mainly in the skin, eyes, lungs,  and  respiratory  tract  in  iranian  veterans.  the  most  common  disease  is bronchiolitis obliterans (bo)). sm incre...

background: the aim of this study was to evaluate over expression of epidermal growth factor receptor (egfr) gene in localized prostate cancers and determine its relation with clinical and pathological factors affecting the progression of the disease. methods: in the tissue samples of the patients with prostate cancer undergoing radical prostatectomy, egfr expression was evaluated by immunohist...

objective(s):previous studies demonstrate that changes in pre-mrna splicing play a significant role in human disease development. furthermore, many cancer-associated genes are regulated by alternative splicing. there are mounting evidences that splice variants which express predominantly in tumors, have clear diagnostic value and may provide potential drug targets. located on the x chromosome, ...

objective(s): we aimed to examine association of gene expression of mor1 and glun1 at mrna level in the lumbosacral cord and midbrain with morphine tolerance in male wistar rats. materials and methods: analgesic effects of morphine administrated intraperitoneally at doses of 0.1, 1, 5 and 10 mg/kg were examined using a hot plate test in rats with and without a history of 15 days morphine (10 mg...

introduction: in order to study the alterations of beta 1 and 2 integrins mrna level in rat lumbar spinal cord following the induction of chronic pain and its effect on the development of tolerance to morphine analgesia, we examined the level of expression of these genes in the presence of chronic pain, which is an inhibitor of morphine tolerance. we used induction of chronic pain alone and in ...

mono-targeting by imatinib as a main antitumor agent does not always accomplish complete cancer suppression. 2,5-dimethyl-celecoxib (dmc) is a close structural analog of the selective cyclooxygenase-2 (cox-2) inhibitor, celecoxib, that lacks cox-2 inhibitory function. in this study, we aimed to show the apoptotic effects of imatinib in combination with dmc in human ht-29 colorectal cancer (crc)...

conclusions expression levels of 1,426 genes were significantly up-regulated in the mutant compared to wt. furthermore, 301 genes were down-regulated with false discovery rates (fdr) of < 0.001 and absolute value of log2 ratio of ≥ 1. results a total of 4,182,944 and 4,182,021 clean tags were obtained from the wt and a nonpathogenic mutant stain (bct89), respectively, and 10,410 differentially ...

conclusions in this experimental study, for the first time in iran the expression and purification of this recombinant protein was done successfully. this recombinant protein could be used as a vaccine candidate and diagnostic purpose in subsequent investigations. results the highest expression of the cytochrome p450 cyp141 protein was obtained by the addition of 1 mm of isopropyl β-d-1-thiogal...

nf-κb pathway is a link between inflammation and cancer and is involved in cellular responses to different stimuli. gastrointestinal lumen is exposed to many inflammatory agents such as foods, free radicals and bacterial or viral antigens. the aim of the present study was to evaluate the possible role of nf-κb1in gastric adenocarcinoma. to detect the relative level of nf-κb1transcript, total rn...

the siberian sturgeon (acipenser baerii) is an economically important species. sturgeon stockassessment during fingerling production is considered to be one of the most difficult phases ofhatchery rearing. the present study investigated the expression of growth hormone (gh)mrna in unfertilized eggs, fertilized eggs, eyed eggs (2 day before hatching), non-viable eggsand newly-hatched siberian st...
