conclusion serum cyfra21-1 is useful as a measure in differentiating malignant from benign pleural effusion. results there was statistically significant difference between mean of serum cyfra21-1 levels of benign (3.9±7.6) and malignant(19.5± 30) pleural effusion (p=0.01). in addition the sensitivity, specificity, positive predictive value and negative predictive value of serum cyfra21-1 at the...

objective(s):acute kidney injury (aki), a syndrome characterized by decreased glomerular filtration, occurs in every 1 of 5 hospitalized patients.  renal ischemia-reperfusion, one of the main causes of aki, is of particular importance in the setting of kidney transplantation. materials and methods: sixty male rats were divided into four groups including control, nephrectomy, sham surgery and re...

the purpose of the current study was to evaluate the anti-inflammatory activity of tetramethlpyrazine on oxazolone-induced colitis mice. spleen mononuclear cells (smc), lamina propria mononuclear cells (lpmc) and peripheral blood mononuclear cells (pbmc) were isolated from oxazolone-induced colitis and normal mice. the colitis cells treated by oxazolone were randomly divided into model, low dos...

in order to investigate the effects of piriformospora indica and trichoderma tomentosum fungi on basil (ocimum basilicum l.) growth under copper nitrate levels, a pot experiment in factorial arrangement with three replicates was done during 2012. treatments were four levels of copper nitrate (0, 100, 200 and 300 mg kg-1 of soil) and four levels of fungal coexistence (non-inoculation control, in...

the main objective of this study is to investigate the production factors productivity in large manufacturing sub-sectors. for this purpose, using statistical data for period 1972-2004, we have tried to study and analyze the trend and level of production factors productivity (partial and total productivity) in each sub-sectors classified according to isic two digits code. the average and margin...

improvements in the two-step synthesis of 1,1,1,3,3,3-hexafluoro-2- (fluoromehoxy)propane (sevoflurane) that result in the product cost reduction, safety level enhancement and positive environmental impacts are described. this process consists of chloromethylation reaction of 1,1,1,3,3,3-hexafluoro-2-propanol (hfip) followed by a halogen-exchange fluorination. this is the first synthesis of sev...

in order to evaluate efficiency of nitrogen fertilizers consumption in a sugar beet monogerm hybrid variety of zarghan, a field experiment was conducted in a loamy soil during 2007 in the research farm of sugar beet seed institute located in karaj. five levels of nitrogen fertilizers including 0 (check), 120, 160, 200 and 240 kg/ha of net nitrogen from urea fertilizer (46 percent of pure nitrog...

soil reduces the hazardous effects of compounds on the components of ecosystem because of self –purification property and the ability for their fixation. playing such a role in soils under redox conditions is performed by pedogenic fe-mn concentrations. in order to investigate cobalt, copper and lead accumulation in iron and manganese concentrations, at first the concentrations were precisely s...
