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 ...

Nanocomposite composed of organoclay(Cloisite 20A-C20A) and Poly lactic acid (PLA) was prepared by solvent casting method. Physical, mechanical, thermal, barrier and microstructure properties of the composite were studied. X-Ray diffraction (XRD) patterns and scannin...

Degradable aliphatic polyesters such as poly(lactic acid) are widely used in biomedical applications, however, they lack functional moieties along the polymer backbone that are amenable for functionalization reactions or could be the basis for interactions with biological systems. Here we present a straightforward route for the synthesis of functional α-ω epoxyesters as comonomers for lactide p...

The enantiomers poly(D-lactic acid) (PDLA) and poly(L-lactic acid) (PLLA) were alternately adsorbed directly on calcium carbonate (CaCO3) templates and on poly(styrene sulfonate) (PSS) and poly(allylamine hydrochloride) (PAH) multilayer precursors in order to fabricate a novel layer-by-layer (LBL) assembly. A single layer of poly(L-lysine) (PLL) was used as a linker between the (PDLA/PLLA) n st...

nanocomposite composed of organoclay(cloisite 20a-c20a) and poly lactic acid (pla) was prepared by solvent casting method. physical, mechanical, thermal, barrier and microstructure properties of the composite were studied. x-ray diffraction (xrd) patterns and scanning electron microscopy (sem) images revealed that the diffraction peak of nanoclay shifted to lower angles and the d-spacing betwee...

To achieve sustained release of 3-ethyl-4-(4-methylisoxazol-5-yl)-5-(methylthio) thiophene-2-carboxamide (BFB0261), a new potent osteogenic compound for treating bone disorders, we prepared film formulations containing BFB0261 and the following newly synthesized biodegradable polymers by a solvent casting technique: poly(D,L-lactic acid) (PLA), poly(D,L-lactic acid-co-glycolic acid) (PLGA), pol...

Despite being a simple dehydration reaction, the industrially relevant conversion of lactic acid to acrylic acid is particularly challenging. For the first time, the catalytic cracking of lactide and poly(lactic acid) to acrylic acid under mild conditions is reported with up to 58 % yield. This transformation is catalyzed by strong acids in the presence of bromide or chloride salts and proceeds...
