Optimization study of the diesters biolubricant oleyl 9(12)-hydroxy-10(13)-oleioxy-12(9)-octadecanoate (OLHYOOT) was synthesized in the presence of sulfuric acid (SA) as catalyst has been done. Optimum conditions of the experiment to obtain high yield% of OLHYOOT were predicted at ratio of OL/HYOOA of 1:1 g/g, ratio of SA/HYOOA of 0.20:1 g/g, reaction temperature 110 °C and 4.5 h of reaction ti...

an efficient method is described for the mild and rapid tetrahydropyranylation of alcohols and phenols using a catalytic amount of n-chlorosaccharin (1 mol %) and 3, 4-dihydro-2h-pyran under solvent-free condition at room temperature. benzylic alcohols and phenols containing electron withdrawing or donating groups in various positions of phenyl ring, cinamyl alcohol, primary, secondary, tertiar...

background: high prevalence of risky behaviors in alcohol dependents have been shown in several studies, but correlation between alcohol abuse and risky behaviors and relapse in patients with opiate dependence has been less investigated. this study aimed to determine the effect of alcohol abuse in rate of risk-taking behaviors in opiate dependents patients treated on maintenance program in nort...

topical drug dosage forms such as ointments and creams can be easily removed through wetting, movement and contact. the new bioadhesive formulations with enhanced local anesthetic effects are needed for topical administration. the adhesive capacity of hydroxypropyl methylcellulose (hpmc) was determined by measuring the maximum detachment force and the adhesion work with an auto peeling tester. ...

the harmful use of alcohol causes an estimated 2.5 million deaths every year, of which a significant proportion occur in the young. alcohol use is the third leading risk factor for poor health globally. in response to harmful use of alcohol, world health organization developed a global strategy to reduce the harmful use of alcohol endorsed by the sixty-third world health assembly in 2010. paral...

Background: Alcohol use could be a risk factor for high risk sexual behaviors and injection especially among injecting drug users (IDUs). Data presented in this abstract extracted from the “Study on situation of HIV, Latent Tuberculosis (TB) and Active TB Infection among IDUs Receiving Harm Reduction Services in Tehran and 5 large cities in Iran” which had been conducted from June to December 2...
