Poly(ethylene glycol) (PEG) and polylactic acid (PLA)-based copolymeric nanoparticles were synthesized and investigated as a carrier for prolonged delivery of insulin via the parenteral route. Insulin loading was simultaneously achieved with particle synthesis using a double emulsion solvent evaporation technique, and the effect of varied PEG chain lengths on particle size and insulin loading e...
fatty acid modified cellulose nanofibers (mcnfs) and tbhq antioxidant were added to poly(lactic acid) (pla) film. the combined effects of the mcnfs and tbhq on the morphological, thermal, mechanical and barrier properties of pla film were analyzed. the morphology of fracture surfaces evaluated by field emission scanning electron microscopy (fe-sem). xrd results showed that the crystallinity of ...
BACKGROUND Rapid local drug clearance of antimicrobials is a major drawback for the treatment of chronic periodontitis. In the study reported here, minocycline-loaded poly(ethylene glycol)-poly(lactic acid) nanoparticles were prepared and administered locally for long drug retention and enhanced treatment of periodontitis in dogs. METHODS Biodegradable poly(ethylene glycol)-poly(lactic acid) ...
Beta-lapachone (beta-lap) is a novel anticancer agent that is bioactivated by NADP(H): quinone oxidoreductase 1 (NQO1), an enzyme overexpressed in a variety of tumors. Despite its therapeutic promise, the poor aqueous solubility of beta-lap hinders its preclinical evaluation and clinical translation. Our objective was to develop beta-lap-containing poly(ethylene glycol)-block-poly(D,L-lactide) ...
