A variety of ocular drug delivery systems, including a controlled release of the drug, drug targeting, and penetration enhancement of the drug, have been investigated. Biodegradable polymers have been widely used as the drug carrier for controlled-release systems. Biodegradable polymers release the drug as they themselves degrade and are finally absorbed within the body. Several ocular drug del...

Lactic acid is widely used in the food, cosmetic, pharmaceutical, and chemical industries and has received increased attention for use as a monomer for the production of biodegradable poly(lactic acid). It can be produced by either biotechnological fermentation or chemical synthesis, but the former route has received considerable interest recently, due to environmental concerns and the limited ...

BACKGROUND A thermal tolerant stereo-complex poly-lactic acid (SC-PLA) can be made by mixing Poly-D-lactic acid (PDLA) and poly-L-lactic acid (PLLA) at a defined ratio. This environmentally friendly biodegradable polymer could replace traditional recalcitrant petroleum-based plastics. To achieve this goal, however, it is imperative to produce optically pure lactic acid isomers using a cost-effe...

The synthesis and characterization of two homoleptic Zn(II)- Mg(II)-complexes based on a simple tridentate {NNO} ligand are reported. production biocompatible atactic poly(lactic acid) (...

Electrospun scaffolds can find numerous applications, including biomedical; for example, tissue engineering. Poly-L-lactic acid is considered suitable these but its low-thermal stability and poor mechanical properties limit this polymer use. The aim of work to obtain a modulation the final characteristics such as fibers dimension, wettability, elasticity, resistance rupture through choice polym...

Starch- graft -poly(lactic acid) is put forward as an efficient compatibilizer of thermoplastic starch – PLA binary blend for a sustainable and high barrier film structures.

Purpose The purpose of this study is to develop an aesthetic treatment protocol for the glutes through combination poly-L-lactic acid (PLLA) and body hyaluronic (HA). Patients methods Six female patients who aimed glutaeal harmonisation were evaluated. treated with combined Rennova Elleva® (poly-L-lactic acid) Body Shape® results evaluated quantitative ultrasonographic analyses. Results showed ...

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...

In this study, Poly (L-lactic acid)/Captopril composite nanofiber membranes were electrospun for drug delivery. Different mass fractions of Poly (L-lactic acid), different ratios of Captopril and the influences of PEG4000 added in the spinning solution are discussed. The morphology, chemical components, the surface areas and pore sizes, wettability of the composite nanofiber membranes were inve...
