[ 1 ] - HPLC Measurement of MDMA Content in Ecstasy Tablets Available in the Black Market of West Azerbaijan Province, Northwestern Iran
Background:Ecstasy, mainly composed of 3,4-methylenedioxymethamphetamine (MDMA), is one of the most popular addictive synthetic drugs. This study was aimed to investigate the amount of MDMA in the ecstasy tablets seized in West Azerbaijan province, northwest Iran and also to assess the relationship between the physicochemical and morphological characteristics of the tablets. Methods: MDMA conte...
[ 2 ] - Separation of STIGMA STEROL using magnetic molecularly imprinted nanopolymer fabricated by sol-gel method
Background & Aims: Magnetically molecularly imprinted polymers (MMIPs) are assumed as kind of sorbent polymers ‎which can separate or determine bioactive compounds from environment fast and specifically. ‎Magnetic properties, stability at various conditions (temperature , ionic strength and pH) and selective ‎function are among the advantages of these polymers in determin...
[ 3 ] - SYNTHESIS OF MOLECULARLY IMPRINTED POLYMER FOR DETERMINATION OF DILTIAZEM BY EXPERIMENTAL METHOD
Background & Aims: In this study, a magnetic molecular imprinted polymer was used to measure the diltiazem drug. Based on the structure and pharmaceutical agent group, methacrylic acid was selected as a monomer for Diltiazem. Ethylene glycol de-methacrylate and azobisisobutyronitrile were used as cross-linkers and polymerisation initiators, respectively. Also, chloroform was used as a porogenic...
[ 4 ] - EVALUATION OF ACRYLAMIDE IN SOME FRIED PRODUCTS MARKETED IN URMIA CITY BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHIA WITH EXPERIMENTAL METHOD
Background & Aims: Acrylamide is an organic chemical with C3H5NO, which has been known to have carcinogens and fertility defects in male animals, humans and human nerves. This carcinogenic compound can be produced by heating the carbohydrates and high temperature cooked foods. Acrylamide can also be found in the main foods such as bread and potatoes, as well as in certain products such as chips...
[ 5 ] - EVALUATION OF PEG 4000 SOLUTION STABILITY IN DIFFERENT TEMPERATURES AND ENVIRONMENTAL CONDITIONS OVER THE TWELVE MONTHS
Background & Aims: Polyethylene glycol (PEG) solution is used as a laxative for the treatment of constipation in children. Due to the preparation of this solution as a compounding ingredient and solution instability as well as unavailability of the exact expiration date of compounding ingredients, it is necessary and important to investigate the stability of PEG solution. Materials & Methods: ...
