Background: Opioid abuse is common in Iran. In recent years, methadone maintenance therapy (MMT) has gained popularity in this country. This study aimed at evaluation concurrent abuse of alcohol in patients under MMT. Methods: A predesigned questionnaire was developed and completed after obtaining verbal consent among 49 subjects under MMT in Kian Rehabilitation Centre during January 2014. Resu...

a new synthesis of a-hydroxycarboxylates and 2-hydroxybenzoates based on the reaction of acetonides of a-hydroxycarboxylic acids and 2-hydroxybenzoic acid with sodium alkoxides in the corresponding alcohols as solvent is described. in general, decreasing the steric hindrance of the reactants and increasing the boiling points of alcohols increased the yields and decreased the required time for t...

An approach for the preparation of noble metal nanoparticles supported on nanostructured oxides is described herein. The based sequential generation and a oxide phase inside cross-linked polymer colloid (microgel). By tuning properties employed microgel, nature amount both can be independently varied. resulting composite colloids are colloidally stable and, upon isolation by precipitation subse...

The paper present results of studies the two-stage preparation C10-C12 tricyclic vicinal amino alcohols from partially hydrogenated condensation products cyclopentadiene and cyclohexa-1,3-diene, by epoxidizing them with hydrogen peroxide in presence cobalt-containing polyoxomolybdate, followed aminolysis oxidate diethylamine, morpholine, or piperidine. structure synthesized compounds was confir...
