background and objective: vascular endothelial growth factor (vegf) and its receptors (vegf-r1 and r2) are major regulators of angiogenesis. this study was designed to assess serum levels of vegf and vegf-r1 and their prognostic significance in newly diagnosed childhood acute leukemia. materials and methods: for this purpose, vegf and vegf-r1 were determined using enzyme linked immuno-sorbant a...

brassica chinensis l. is a popular vegetable, especially in asian dishes. for plant growing withinorganic fertilizer, cadmium (cd) has been one of the highest metal and health-risk factors included. thisresearch aimed to assess the bioaccumulation of cd by the plant and its genetic changes. the plant was grownin the soil supplemented by cd at 0, 15, 30, 60 and 120 mg/kg. the accumulations in th...

background: factor xiii (fxiii) is a heterotetramer composing two subunits including fxiii-a and fxiii-b. several common gene variations were observed in fxiii-a gene with obvious ethnic difference. this study assessed pattern of tyr204phe as a common fxiii-a gene variation among iranian population. materials and methods: this study was conducted on eighty iranian unrelated individuals. genotyp...

patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). in this survey we detected factor v and viii inhibitor in ten patients with combined deficiency of factors v and viii from north east of iran (khorassan province). it was revealed in our survey that eight patients had both factor v and factor viii inhib...

the present study aimed at investigating the beneficial effects of co-administering granulocyte colony–stimulating factor (g-csf) and stem cell factor (scf) in a model of chronic liver injury induced by thioacetamide (taa). biochemical and histopathology- cal examinations were performed on serum and liver specimens. at the end of the treatment period, the rats were anesthetized with ether, seru...

response modification factor (r factor) is one of the seismic design parameters to be considered in evaluating the performance of buildings during strong motions. this paper has tried to evaluate the response modification factor of concrete coupled shear wall structures with various length/depth ratios of spandrel beams. the effect of diagonal reinforcement of spandrel beam was also evaluated o...
