the polymer being selected from polylactic acid, polyglycolic acid and lactic acid-glycolic acid copolymer, according to the present invention, provides a drug carrier which encapsulates a low molecular drug efficiently, which can control a sustained release period for a long term, which can control...
Utilizing a nanoprecipitation method enables the production of NPs using biodegradable and biocompatible polyester homopolymers like polylactic acid (PLA), polylactic-co-glycolic acid (PLGA), and polycaprolactone (PCL). These polymers have the capability to encapsulate or adsorb drug compounds. With suita...
Although chitosan (CS) and hyaluronic acid (HA) are polymers derived from natural sources, we allotted a separate section (3.5 section) to discuss their role in the synthesis and modification of nanoparticles in autophagy regulation. In cases where autophagy possesses a tumor-suppressor role, the ...
If anything, my skin has felt softer and smoother since using this, maybe due to the fruit enzymes that provide some minor exfoliation effect, which I prefer over stronger acids. It also has glycolic and lactic acid, but the pH isn’t low enough for them to really have much impact....
(d,l-lactic-co-glycolic acid), polyethylene glycol, poly-methyl-methacrylate) to natural (e.g., collagen, agarose, alginate, gelatin, chitosan, fibrinogen, hyaluronic acid) origins. The gels are crosslinked by UV light, temperature or chemicals. Hydrogels have the advantage that they can be ...
ECM provides mainly the structural support and regulatory milieu for cellular growth and communications with other cells. Synthetic polyesters such as Poly Lactic-co-Glycolic Acid (PLGA) are biodegradable, biocompatible and have been approved by the Food and Drug Administration. However synthetic ...
A variety of synthetic polymers including polylactic acid (PLA), poly(lactic-co-glycolic) acid (PLGA), polyethylene glycol (PEG), and polyethyleneimine (PEI) have been utilized in nanoformulations that arrange them into polymer micelles, polymerosomes, polymer conjugates, or polymeric nanoparticles....
long periods, a stable additional acid is advantageously combined with the ascorbic acid. This acid may be any acid which makes it possible to obtain the desired acidic buffering effect. This additional acid is preferably an α-hydroxy acid chosen from lactic acid, glycolic acid and citric acid...
copolymers of ethylene glycol and propylene glycol, polyoxyethylated polyols, polyvinyl alcohol, polysaccharides, dextran, polyvinyl ethyl ether, biodegradable polymers such as PLA (poly(lactic acid) and PLGA (polylactic-glycolic acid), lipid polymers, chitins, hyaluronic acid, and combinations thereof...
(glycolic acid), poly(glycolic acid-cotrimethylene carbonate), polyphosphoesters, polyphosphoester urethane, poly (amino acids), cyanoacrylates, poly(trimethylene carbonate), poly(iminocarbonate), copoly(ether-esters), polyalkylene oxalates, polyphosphazenes, polyiminocarbonates, and aliphatic ...
