Plant extracts are extensively researched as a source of green corrosion inhibitors. Herein, we report on a highly efficient and thermally stable corrosion inhibitor from the stem extract of high-altitude shrub Berberis aristata. The corrosion inhibition efficiency (IE) of the extract was tested in 1.0 M H2SO4 for the corrosion protection of mild steel (MS) by using gravimetric and electrochemi...

this article elaborates on the experience of higher medical education evaluation in iran. although institutional evaluation in iran started in about a decade ago, recent policies of the government to increase quality of higher medical education have contributed to a special effort in designing and implementing evaluation mechanisms in university systems in iran. among these a process of interna...

in the islamic era, mausoleums were considered as the most important after mosques. constructing these buildings dates from the fourth century after hijrah, coinciding with the establishment of the earlier post -islamic dynasties in east and north east of iran. this tradition continued in later islamic periods in two basic rectangular and tomb tower types. the significant point about these buil...

objective(s):emap-like protein 5 (eml5) is a new echinoderm microtubule-associated protein that is expressed in the central nervous system. the aim of this study was to investigate the expression profile of eml5 in the anterior temporal neocortex of patients presenting with intractable epilepsy (ie). materials and methods:western blot assays were performed to determine eml5 expression in 36 sur...

background: molecules expressed on the surface of infected erythrocytes (ie) with plasmodium falci-parum play important roles in malaria pathogenesis and immune evasion. some of these molecules are specific adhesive ligands mediating adhesion of ie to the vascular endothelium. in the current study, the antigens exposed on the surface of ie with different isolates and various binding subpopulati...
