background: high and intermediate energy protons are not able to form a track in a solid state nuclear track detector (ssntd) directly. however, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a ssntd. materials and methods: the protons with primary energies of 9.6 and 30 mev available at the cyclotron accelerator with corresponding lo...

objective(s):blactx-mand blaper are two genes that encode class a extended-spectrum β-lactamases (esbls) and can be responsible for therapeutic problems. this study was carried out to evaluate the molecular properties of these genes in clinical isolates of enterobacteriaceae by polymerase chain reaction (pcr), restriction digestion and sequencing. materials and methods: during six months, start...

background and aims:in neurodegenerative disorders,oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages which can lead to apoptosis. pro-apoptotic and anti-apoptotic gene expressions are changed during the cell differentiation that affect cell viability and differentiation. therefore, this study was conducted to determine the effects of hyd...

larger tumor burden leads to higher serum ca-125 levels and the ability to perform optimal tumor cytoreduction of advanced ovarian cancer is also a function of tumor bulk. the purpose of this study was to identify the ability of preoperative serum ca-125 to predict possibility of optimal primary tumor cytoreduction in epithelial ovarian carcinoma (eoc). a total of 90 patients with eoc were eval...

conclusions in this study, the l-lps immune response of bovine cells was significant, indicating that tlr2 is the predominant receptor for l-lps. due to l-lps endotoxin-like activity, we found a strategy through using bmap-28 to prevent l-lps-induced tlr2-dependent immune activation in bovine cells. materials and methods in this study, l-lps-induced proinflammatory cytokine production in bovine...

conclusions according to the high functionality of the produced recombinant vector, it seems a good applicable tool for making an indicator cell line in subsequent basic and drug studies. results recombinant vector, pgl4ltr-luc, has expression levels of more than 50 folds compared to the control when co-transfected with the tax expressing vector into hek 293t cells. moreover, cells display more...

in order to investigate the effects of municipal waste compost and benefit fungi of trichoderma species on seedling emergence parameters, growth and some micronutrients uptake of garden cress a pot experiment was carried out in factorial arrangement based on randomized complete block design with 3 replications. treatments consisted of three levels of municipal waste compost (15, 30, 45 mg ha-1 ...

background: prostate specific antigen (psa) has been used as a screening test for the early detection of prostate cancer (pc) for many years. although the introduction of psa test led to a considerable increase in reported prostate cancer cases, there is still some controversy over the sensitivity and specificity of this marker in distinguishing pc patients from those with benign prostate hyper...

background poly 3-hydroxybutyrate (phb), a class of poly hydroxyalkanoates (phas), is a group of bacterial storage polymers, produced by various microorganisms in response to nutrient limitation. phas are biodegradable polymers which could be a good substitute for current petrochemical plastics. phb has been synthesized during three enzymatic steps including three genes. objectives our aim was ...
