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...

BACKGROUND AND PURPOSE We have previously demonstrated that the local delivery of monocyte chemotactic protein-1 (MCP-1) via an MCP-1-releasing poly(lactic-co-glycolic acid)-coated coil promotes intra-aneurysmal tissue healing. In this study, we demonstrate that interleukin-6 (IL-6) and osteopontin are downstream mediators in the MCP-1-mediated aneurysm-healing pathway. METHODS Murine carotid...

Biodegradable thermogelling copolymer hydrogels have great applicative potential in areas such as sustained drug release, gene delivery and tissue engineering. These injectable materials can be implanted in the human body with minimal surgical intervention. The thermosensitive copolymers have been incorporated with a variety of biocompatible and biodegradable components such as poly(D,L-lactic ...

In this study, we sought to develop strategies for improved endothelialization of a new polymer coating for vascular stents. Surface enhancement of the new poly-1,8-octanediol-co-citric acid (POC) polymer was achieved through conjugation of anti-CD34 antibody and incorporation of vascular endothelial growth factor and basic fibroblast growth factor-containing poly-lactic-co-glycolic acid microp...

The present research was aimed to develop and characterize a sustained release dry powder inhalable formulation of salbutamol sulphate. The salbutamol sulphate microparticles were prepared by solvent evaporation method using biodegradable polymer poly (D,L-lactic-co-glycolic acid) to produce salbutamol sulphate microparticle mixed with carrier respirable grade lactose for oral inhalation of dry...
