Lactic acid has been shown to have the most promising application in biomaterials as poly(lactic acid). L. rhamnosus ATCC 10863 that produces L-lactic acid was used to perform the fermentation and molasses was used as substrate. A solution containing 27.6 g/L of sucrose (main composition of molasses) and 3.0 g/L of yeast extract was prepared, considering the final volume of 3,571 mL (14.0% (v/v...
Purpose: The purpose of this study is to compare the time-course changes in condylar long axis and skeletal stability after sagittal split ramus osteotomy (SSRO) with unsintered hydroxyapatite (u-HA) / poly-L-lactic acid (PLLA) plate, PLLA plate versus titanium plate. Patients and Methods: Of 60 Japanese patients diagnosed of mandibular prognathism, 20 underwent SSRO with u-HA/PLLA plate system...
Background and Objective: Poly D,L-lactic-co-glycolic acid (PLGA) is known as biodegradable and biocompatible polymer. These polymers have recently received much attention in tissue engineering. The aim of this study was to investigate the biological behavior of the bone marrow stromal cells (BMSCs) in culturing with PLGA nanofibers coated with poly-L-lysine or gelatin. Materials and Methods: I...
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...
