background increasing evidence indicates that opiate users and methadone maintenance patients (mmps) are impaired in executive control tasks and response inhibition behavior compared to healthy individuals; however, the cognitive functional difference between opiate addicts and mmps has not been clarified. objectives this study employed go/no-go tasks to evaluate the response inhibition behavio...

onion (allium cepa) contains high levels of flavonoids. although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. fresh filtered juice of onion was prepared and its inhibitory effect on guinea ...

glutathione s-transferases (gsts) are widespread in fasciola. hepatica parasite and sheep liver tissue. study of gsts inhibition assays in f. hepatica and sheep liver tissue are a priority of chemotherapeutic targets in parasitic liver diseases including human fascioliasis in iran. in this research, the whole extract of f. hepatica and sheep liver tissues were purified and eluted for sodium dod...

Corrosion of Aluminum metal at pH 10 has been controlled by dicarboxylic acids such as oxalic acid (OA) and adipic (AA).The Inhibition efficiency (IE) determined the classical weight loss method. The maximum inhibition offered (AA) 250 ppm Zn2+ 50 system are 88 96%. To determine values Linear Polarization Resistance (LPR) corrosion Current (Icorr), potentiodynamic polarization study used.

Chrysoidine dye was examined as an inhibitor for mild steel in 1N HCl using weight loss, gasometric and thermometric methods. Parameters such as inhibition efficiency and corrosion rates were evaluated. The inhibition efficiency was found to increase with increase in the inhibitor concentration. To study the adsorption of the inhibitor on the mild steel surface, adsorption isotherm was plotted.

The inhibition of corrosion on mild steel in 1M H2SO4 by a heterocyclic compound namely cefuroxime axetil has been studied by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy methods. The adsorption characters of the inhibitor on mild steel, free energy change and energy of activation of the inhibition process have been calculated from the results. The inhibi...
