physical, mechanical and structural properties of poly(lactic acid) (pla)-basedfilms containing different amounts of nanoclay and cellulose prepared bysolvent casting method were examined. physical properties including thickness,transparency and color did not change significantly with addition of nanoparticles to the polymer matrix. x-ray diffraction (xrd) patterns showed that pure pla has a se...

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...

Implant-based breast reconstruction after mastectomy offers excellent cosmetic results in select individuals. However, this technique may result in a step-off between the implant and the soft tissue of the chest wall, which can be problematic in the extremely thin patient. Also, the removal of soft tissue can result in prominent ribs and visible intercostal spaces. A number of surgical options ...

BACKGROUND Hill and valley scarring is 1 of 3 atrophic scar types that occur as a result of acne, becoming more apparent with facial skin aging. Treatment includes resurfacing techniques and the use of injectable fillers. Poly-L-lactic acid is an injectable collagen builder that has been used for the treatment of HIV-associated lipodystrophy and cosmetic enhancement. OBJECTIVE To determine th...

Bones constructed by tissue engineering are being considered as valuable materials to be used for regeneration of large defects in natural bone. In an attempt to prepare a new bone construct, in this study, proliferation and bone differentiation of marrow-derived mesenchymal stem cells (MSCs) on our recently developed composite scaffolds of nano-, micro-hydroxyapatite/ poly(l-lactic acid) were ...

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 ...
