introduction: this study was conducted to determine the possible beneficial results of l-arginine on prefrontal cortex of rats which impressed by immobilization stress to define the synchronous impression of stress and nitric oxide (no) on evolution of prefrontal cortex of rats after birth. methods: forty-eight one month, male wistar rats were divided into two groups: stressed and non-stressed....

gavane-gaz-angubin (persian manna) belongs to astragalus genus (leguminosae). this plant is one of the most important species in iran for its medicinal value. considering the low propagation rate of this plant from seed and cutting, the feasibility of in-vitro propagation of this plant was investigated. effect of different types and concentrations of cytokinins such as bap, kin, and ze (0.5, 1,...

background: the cuprizone multiple sclerosis (ms) animal model is characteristic for toxic demyelination and represents a reversible demyelination and remyelination system. it has been shown that green tea epigallocatechin-3-gallate (egcg) might be effective in improving the symptoms and pathological conditions associated with autoimmune inflammatory diseases in several animal models. objective...

copolymerization of aniline and 2-anilinoethanol was carried out by electrochemical and chemical polymerization. homo and copolymer thin films were synthesized electrochemically, under cyclic voltammetric conditions in aqueous solutions of sulfuric acid as electrolyte at room temperature. the films were deposited on the surface of working electrode [glassy carbon ()gc)(] versus ag/agcl electrod...

normal 0 false false false en-us x-none ar-sa gossypibomas or retained surgical foreign bodies, although uncommon causes of abdominal lumps, still remain a major cause of concern for surgeons worldwide. their early identification and treatment are mandatory to prevent morbidity as well as mortality. the major diagnostic dilemma still remains in the vagueness of presentation of this callous enti...

nitrogen forms exert significant effects on physiological and morphological characteristics of plant. in this study, the effects of ammonium, nitrate, and ammonium-nitrate on pepper plants were investigated in soil culture, as well as in solution culture. in the soil culture, 3, 4-dimethylpyrazole phosphate (dmpp) was used as a standard nitrification inhibitor to guarantee the presence of ammon...

background: meict is the first chlorotoxin-like peptide isolated from the iranian scorpion mesobuthus eupeus. chlorotoxin (ctx) is a neurotoxin that specially binds to (mmp-2) on ma-lignant cells and now is used in treatment of glioma. in the present study, we have used homology modeling to propose the 3d structure of meictand analyze its interaction with mmp-2 and its snp types. methods:the st...

new derivatives of 2-[2-(2-chlorophenoxy)phenyl]-1,3,4-oxadiazole as candidates for agonistic effect on benzodiazepine receptors were synthesized. conformational analysis and superimposition of energy minima conformers of the novel compounds on estazolam, a known benzodiazepine agonist, revealed that the main proposed benzodiazepine pharmacophores were well matched. in pharmacological evaluatio...
