vitiligo is a pigmentation disorder in which inflammatory mediators such as cytokines have a pivotal role in disease's pathogenesis. interleukin 17 (il-17a) is a proinflammatory cytokine which is involved in the induction of several proinflamatory mediators such as cyclooxygenase 2 (cox2). the aim of this study was to investigate the gene expression of il-17 and cox2 in peripheral blood leukocy...

β-cyclodextrin sulfuric acid as a green lewis acid catalyst has been applied for the preparation of bis(indolyl)methanes, tris(indolyl)methanes and 3,3'-diindolyloxindole derivatives by the condensation of indoles with various carbonyl compounds in aqueous media with high to excellent yields.

utilization of the new compatibilizers to improve matrix/filler interface adhesion and also, nanoparticles to improve the properties of wpc products have always been of interest to researchers. in this study, the effect of oxidized polypropylene in solution phase as a comptibilizer and nanoclay particles on the physical and mechanical properties of wood fiber reinforced polypropylene composite ...

the essential oils isolated by hydrodistillation from the leaves of two eucalyptus gillii maiden and e. microcarpa subsp. macrocarpa hook were analysed by gc and gc/ms. the main components identified in e. gillii oil were 1, 8-cineole (79.5%), trans-pinocarveol (8%) and ?-pinene (2.7%), and in e. microcarpa were 1, 8-cineole (77.3%), ?-pinene (5.6%) and terpin-1-ol (5.1%). oils with high conten...

conclusions since the severity of the behavioral symptoms in the 6-ohda-induced model of parkinson disease reflects the degree of the lesion in substantia nigra (sn) dopaminergic neurons, it is suggested that using the combination had neuroprotective effects. the obtained data suggest a synergistic neuroprotective and antiparkinsonian effect for flu, glib and b com. at least, a part of this eff...

to inspect the effect of methyl salicylate (mesa) vapor on fruit shelf life quality in kiwifruit (actinidia chinensis cv. hayward) an experiment was carried out in citrus research institute, ramsar, iran in 2006-2007. the experiment was based on a completely random design of three replications. the treatments consisted of mesa at five rates (0, 8, 16, 24 and 32 µl/l) and storage time of five le...

it   was   recently   demonstrated   that   5-(5-nitrofuran-2-yl)-1,   3,   4-thiadiazoles   with piperazinyl-linked benzamidine substituents are effective in vitro against leishmania major. following on this evidence, we used colorimetric assay of acid phosphatase activity in the promastigotes  as  an  indicator  for  cell  viability.  also  we  studied  the  effect  of  these compounds on ind...

the catalytic air oxidation-trimerization of alcohols was carried out with hetropolyacids. in the presence of hetropolyacid formation of cyclotrimers of alcohols and aldol condensation products was observed. the 1,3,5-trioxanes were major and aldol condensation compounds were minor products.
