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...

Poly(vinyl alcohol) and poly(vinyl pyrrolidone) were blended and films were obtained by casting method. Glutaraldehyde, hydrochloric acid and lactic acid were added to investigate their effect on mechanical properties, swelling and solubility of the blends with the aim to find a possible material candidate for medium or long term implants. Combination of all three additives (lactic acid, glutar...

Poly(dG-dC) . poly(dG-dC) was modified by reaction with N-acetoxy-N-acetyl-2-aminofluorene (N-AcO-AAF). Two samples with 6.6% and 8.5% modified bases were prepared. The modified bases are randomly distributed along the polymer chain, as deduced from competition experiments between antibodies against N-2-(guanosin-8-yl)-acetylaminofluorene, modified poly(dG-dC) . poly(dG-dC), and modified DNAs. ...

it is possible to develop new biodegradable active packaging by coating biopolymers on paper-based packaging material and also incorporating proper antimicrobial agents into coating structure. in this study bacterial contamination of two commercial cardboard were evaluated.in order to manufacture an appropriate antibacterial packaging material, coating of chitosan-poly vinyl alcohol blends with...

Polyaniline (PANI) nanocomposite has been successfully prepared in aqueousmedia by the chemical polymerization of aniline with ammonium peroxydisulphateas an initiator in the presence of a steric stabilizer such as sodium dodecylbenzenesulfonate(DBSNa), Poly(vinyl pyrrolidone) (PVP), poly(vinyl alcohol)(PVA), poly(ethylene glycol) (PEG) and hydroxypropylcellulose (HPC). Thechemical structure, m...

the purpose of this study was to investigate the effect of additives, poly(ethylene glycol) (peg) 1450, poloxamer 407, polyvinyl alcohol (pva) and sodium chloride in order to improve physico-chemical characteristics, encapsulation efficiency and in vitro release of bovine serum albumin, form poly(d,l-lactic-co-glycolic acid) (plga) microparticles prepared by the w/o/w solvent evaporation method...

in this study, poly(ethylene-co-vinyl alcohol) (evoh) as a novel biocompatible polymeric scaffold was surface modified by succinylation to get evohs and further pegylated to improve structural properties using methoxypolyethylene glycol (5000 da) succinate (pegs) along with targeting with retinoic acid (ra) to get final modified active and passive targeted conjugate (pegs-evohs-ra) to evaluate ...

proton exchange membrane fuel cells (pemfcs) are electrochemical devices that show the highest power densities compared to the other type of fuel cell. in this work, nanocomposite membranes used for proton exchange membrane fuel cells as poly(vinyl alcohol)/la2ce2o7 (pva-lc) with the aim of increasing the water uptake and proton conductivity. glutaraldehyde (ga) was used as cross linking agent ...
