this study examined the effects of a protein rich diet on coping neurotransmitter levels in orally administered ampicillin–induced neurotoxic rats compared with propionic acid (pa) models of autism. 40 young male western albino rats were divided into four groups. the first group served as control and received phosphate buffered saline orally; the second group serving as autistic model was treat...

we have reported the fabrication of boric acid incorporated into surface of magnetite nanoparticles. the catalyst was characterized using spectroscopic, magnetic and thermal techniques (ft-ir, sem, xrd, icp, vsm and tga). it catalyzed mukaiyama aldol reaction of a ketene silyl acetal type nucleophile ((1-methoxy-2-methylprop-1-enyloxy) trimethylsilane), and various aldehydes (aromatic, aliphati...

oxidative stress is one of the important mechanisms involved in dexamethasone (dex)-induced hypertension. protocatechuic acid (pca) is a natural compound with high antioxidant capacity. in this investigation, the effect of pretreatment with pca was studied in dex-induced hypertensive male wistar rats. for induction of hypertension, dex was injected subcutaneously for 14 days. pca (50, 100 and 2...

many organisms produce lactic acid by fermentation, but most industrially important strains are from the genus lactobacillus and rhizopus oryzae. l(+)-lactic acid is the only optical isomer for use in pharmaceutical and food industries because human body is only adapted to assimilate this form. in this research, six strains of lactobacillus and four strains of r. oryzae (known as high producer)...

the aim of this study was to compare three routine precipitation methods, including: acetone, tca/acetone wash and tca/acetone. 30 plasma samples were precipitated using above mentioned three methods. pellets were dissolved in rehydration solution and protein quantification was done for this solution. according to statistical analysis using spss ver 16.0 software and one-way anova test, the pro...

introduction: toluene is an organic solvent that it is one of the byproducts in the coke industry. exposure to toluene causes central nervous system dysfunction and others disorders. many workers are exposed to toluene due to leakage from tracks. therefore the aim of this study was to determine the levels of exposure through environmental and biological monitoring of toluene methods: air toluen...

background kelussia odoratissima mozaff. is one of the newest genera of umbelliferae which is represented by only one species. this sweet-smelling, self-growing monotypic medicinal plant is endemic to a restricted area in west of iran and is locally called karafse-koohi. the aerial parts of the plant are commonly used as a popular garnish and a sedative medicinal plant. there are several report...

background: rise in serum homocysteine level may be associated with higher prevalence of cardiovascular diseases in hypothyroidism. levothyroxine can partly diminish serum homocysteine level. folic acid participates in homocysteine metabolic cycle in the human body. the effect of concomitant administration of folic acid and levothyroxine on serum homocysteine level was evaluated in the present ...
