a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
هدف از انجام این تحقیق بررسی نقش احتمالی داروهای نیتریک ارژیک در اثرات پاداشی نیکوتین در موش بزرگ آزمایشگاهی نر بود. از یک روش ترجیح مکان شرطی شده یا cpp (conditioned place preference) برای اندازه گیری اثرات پاداشی نیکوتین استفاده شد و در روز تست علاوه بر نمره شرطی شدن تعداد رفتارهای وابسته به دوپامین نیز شمارش شد. نتایج نشان داد که تجویز داخل صفاقی نیکوتین باعث القای cpp معنی دار شد در حالی که...
this paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. among common magnetic nanoparticles, magnetite (fe3o4) and maghemite (g-fe203) are popular candidates because of their biocompatibility. natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...
L-Arginine (Arg or R) is a non-toxigenic, metabolically versatile and conditionally essential amino acid. Single-pot synthesis of Arg modified magnetic nanoparticles (RMNPs) was achieved using magnetite nanoparticles (MNPs) and binary function of Arg as a functional group and an alkali precipitator. This modification is supposed to offer several advantages to the MNPs from a bio-application vie...
background: heavy metals, even at low concentrations, are harmful to human health and environment. cadmium as a heavy metal is highly toxic and can cause serious threat to living organisms. this research was designed to evaluate the adsorption potential of modified magnetic iron nanoparticles by 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol ligand for the removal of cadmium ions from water solu...
The magnetic adsorbent nanoparticle was modified using cationic surface active agent. Zinc ferrite nanoparticle and cetyl trimethylammonium bromide were used as an adsorbent and a surface active agent, respectively. Dye removal ability of the surface modified nanoparticle as an adsorbent was investigated. Direct Green 6 (DG6), Direct Red 31 (DR31) and Direct Red 23 (DR23) were used. The charact...
Changes in extra and intracellular neurotransmitter amino acids concentration in the early stage of acute cerebral ischemia have been reported. In this the study, serum level of gamma aminobutyric acid (GABA) and L-Arginine in acute ischemic stroke patients was assessed. 60 patients with acute ischemic stroke and sixthy healthy volunteers as a control group were assessed. Serum GABA was measure...

Background and Aim: Agricultural poisons are one of the most important groups of pollutants in agricultural industries that cause environmental pollution. The main objective of this research was to remove imidacloprid from contaminated water by using modified magnetic-silica core-shell nanoparticles. Materials and Methods: This study was conducted at the laboratory scale and batch system. The ...
