poly-drug use refers to the use of two or more substances at the one time or repeatedly. it is common among both recreational and regular drug users across the world. poly-drug use is a great contributor to the global number of deaths related to drug overdose. in this case, the likelihood of drug overdose and its pertaining complications in an individual is higher especially when benzodiazepine...
two new samples of poly(amide-imide)/nanocomposites containing bicyclo segment and dibenzalaceton moiety in the main chain were synthesized by a solution intercalation technique. poly(amide-imide) (pai) 8 as a source of polymer matrix was synthesized by the direct polycondensation reaction of n,n´-bis(4-carboxyphenyl)bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic diimide 3 with 2,6-bis(4-amino...
background: the antioxidant components have been identified in some pine species. antioxidant properties of proantocyanidins reduce free radicals induced by dna fragmentation and lipid proxidation and also proanthocyanidines could curb lipid peroxidation. objective: in this study, we analyzed different parts of pinus eldarica (bark, seed and needle) and assessed their antioxidant contents. meth...
the poly(ethyleneimine)-functionalized silica has been developed successfully as an effective adsorbent for the adsorption removal of cu(ii) ions from electroplating wastewater. the influences of ph, contact time and initial concentration of cu(ii) ions on the adsorption capacity and the effect of adsorbent dosage on the removal efficiency of cu(ii) ions from electroplating wastewater were inve...
nanofber mats of poly(ε-caprolactone)/nanoclay nanocomposites were fabricated by electrospinning. the effects of the solution concentration and the nanoclay content of nanocomposite materials on the fnal nanofber structure were investigated. morphology and diameter of the nanofbers were studied using optical and scanning electron microscope. it was observed that the poly(ε...
Background and Objective: Poly D,L-lactic-co-glycolic acid (PLGA) is known as biodegradable and biocompatible polymer. These polymers have recently received much attention in tissue engineering. The aim of this study was to investigate the biological behavior of the bone marrow stromal cells (BMSCs) in culturing with PLGA nanofibers coated with poly-L-lysine or gelatin. Materials and Methods: I...
