in this research, nanoporous silica (sba-15) was physically functionalized using2-(2-nitrobenzylideneamino) guanidine compound. this functionalized sba-15 was utilized as a new sorbentfor separation and preconcentration of some lanthanide ions. inductively coupled plasma optical emissionspectrometry (icp-oes) was used as a detection technique. the preconcentration factor of the method is 100and...

due to the anti-diabetic and antioxidant activity of green tea epigallocatechin-gallate (egcg), this research study was conducted to evaluate, for the first time, the efficacy of chronic treatment of egcg on alleviation of hyperalgesia in streptozotocin-diabetic (stz-diabetic) rats. male wistar rats were divided into control, diabetic, egcg-treated-control and diabetic and sodium salicylate (ss...

in order to investigate the effect of different irrigation regimes on yield and leaf proline content of a spring isfahan local variety of safflower, a field experiment was conducted as split plot in randomized complete block design with three replications at the research station of shahrekord university in 2013-2014. the main factor consisted of four different irrigation regimes (irrigation aft...

a two-dimensional nanolayered polyoxomolybdate, [4,4´-h2bipy] [mo7o22].h2o (1), where 4,4´-bipy = 4,4´-bipyridine, was prepared and characterized by ft-ir and atomic absorption spectroscopies, transmission electron microscopy (tem), x-ray single crystal and powder diffraction (xrd), and thermogravimetric analysis. the catalytic performance of 1 was assessed in the epoxidation of some olefins em...

abstract background and objective: parkinson's disease (pd) is an age-related neurodegenerative disorder with massive loss of dopaminergic neurons in the substantia nigra pars compacta. l-dihydroxyphenylalanine (l-dopa) substitution is still the gold standard therapy for pd. however, there has been little information available on neuroprotective and regenerative therapies for pd. due to the neu...

background and purpose:   methods:   results:   conclusion:

background: glioblastoma is the most common and most malignant cancer of central nervous system. targeted radiotherapy is an effective method toward its treatment. iododeoxyuridine (iudr) is a halogenated thymidine analogue known to be effective as a radiosensitizer in human cancer therapy. in this study we have evaluated the combination effects of 2-methoxyestradiol, an inhibitor of hypoxia in...

sesame is one of the most important oil crops in iran. high oil seed content makes it difficult to store for a long period of time. this study was conducted in 2012 to evaluate possible physiological and biochemical changes in seed under different storage conditions. various seed moisture content (5, 9, 13, and 17%) were evaluated under five temperatures (5, 15, 25, 35, 45) for six month. germi...

background and purpose: future generalists require in depth exposure to primary care practice and the opportunity to work with successful generalist role models.changes in hospital practice, patient availability, increased student numbers and their expectations and a redefinition of expected learning outcomes are changing the emphasis of clinical teaching away from traditional inpatient setting...
