Robust homoleptic zinc catalysts offer new opportunities for recycling polyesters such as poly(lactic acid) and poly(ethylene terephthalate) to obtain platform molecules in a plastics circular economy approach.

We examine different approaches for the controlled release of L-lactate, which is a signaling molecule that participates in tissue remodeling and regeneration, such as cardiac muscle tissue. Robust, flexible, self-supported 3-layers films made two spin-coated poly(lactic acid) (PLA) layers separated by an electropolymerized poly(3,4-ethylenedioxythiophene) (PEDOT) layer, are used loading delive...

Background: Platelet-rich plasma (PRP) is blood containing an above baseline level of platelets and growth factors. Recently, has come to the attention aesthetic surgeons, with burgeoning new applications ranging from hair restoration soft tissue augmentation. Injectable Poly-D,L-Lactic Acid (PDLLA) a biostimulator rather than traditional filler, which provides immediate volumetric improvement....

Poly(lactic acid) is biodegradable polymer derived from renewable resources and non-toxic, which has become most interested polymer to substitute petroleum-based polymer. However, it has low glass transition temperature and poor gas barrier properties to restrict the application on hot contents packaging and long-term food packaging. The objectives of this research are: (a) to reduce coagulatio...

The use of selective barriers as resorbable membranes has become a routine clinical procedure for guided bone regeneration. Therefore, the production with low inflammatory potential during their resorption process goal considerable number researches. Aim: purpose present study was to evaluate biocompatibility poly (L- lactic acid) (PLLA) and biocelulose (BC) inserted in subcutaneous tissue on d...

Atmospheric pressure non equilibrium plasma treatments have been implemented to produce solvent-free Poly-L-lactic acid (PLLA) scaffolds, to improve biocompatibility of PLLA mats and to increase electrolyte uptake of Poly(vinylidene fluoride) (PVDF) separators for lithium batteries. It has been observed that plasma treatments are a suitable way to improve polymeric solution electrospinnability,...

Absorbable plates are used widely for fixation of facial bone fractures. Compared to conventional titanium plating systems, absorbable plates have many favorable traits. They are not palpable after plate absorption, which obviates the need for plate removal. Absorbable plate-related infections are relatively uncommon at less than 5% of patients undergoing fixation of facial bone fractures. The ...

BACKGROUND Facial rejuvenation techniques have evolved in recent decades driven by a paradigm shift to restoration of lost volume, and an increase in the number of available products. As clinical experience has increased, practitioners have further refined the use of these products. OBJECTIVES To share observations and practical recommendations based on clinical experience with the aesthetic ...

The purpose of this article is to discuss current techniques used with poly-l-lactic acid to safely and effectively address changes observed in the aging face. Several important points deserve mention. First, this unique agent is not a filler but a stimulator of the host's own collagen, which then acts to volumize tissue in a gradual, progressive, and predictable manner. The technical differenc...
