Vocal cord paralysis (VCP) is considered as a closure of glottal cavity during phonation. Vibration impairment in the vocal mucosa to loss voice result glottic space not closing. Many implant biomaterials are used for VCP. These implants, which can be applied restore function paralyzed and improve sound quality, Medialization thyroplasty (MT) type 1 surgeon. The aim this study produce customiza...

Abstract A combination of roll-to-roll coating and nanoimprinting technique is proposed for large-scale fabrication porous nanosheets. Poly ( d , l -lactic acid) (PLA) in 2-methoxy-1-methylethyl-acetate coated on polypropylene substrate to obtain nanosheets with thickness above ca. 95 nm. Roller a nickel mold applied fabricate pores diameter 1.2 μm. The imprinted PLA 129 nm can be directly peel...

BACKGROUND The objective of this study was to investigate the in vivo effect of bioactive composites with poly(lactic acid) (PLA) or polycaprolactone (PCL) as the matrix, reinforced with bioplastic flax fibers, on the surrounding muscle tissue. METHODS Materials of pure PLA and PCL and their composites with flax fibers from genetically modified plants producing poly-3-hydroxybutyrate (PLA-tra...

Alkali-treated bagasse fiber was used as a process variable for optimization of the properties polybutylene succinate/poly(lactic acid)-based biocomposites using Box-Behnken design (BBD) and response surface methodology (RSM). The optimum conditions three factors, i.e., NaOH-treated (0.55 to 1.65 g), succinate (1.1 2.3 poly(lactic acid) (2.2 3.4 g) on bending strength biocomposite were investig...

Lactic acid is the monomer unit of the bioplastic poly-lactic acid (PLA). One candidate organism for lactic acid production is Pichia pastoris, a yeast widely used for heterologous protein production. Nevertheless, this yeast has a poor fermentative capability that can be modulated by controlling oxygen levels. In a previous study, lactate dehydrogenase (LDH) activity was introduced into P. pas...

Enantiomeric stereo random copolymers (SRCs), l-lactic acid-rich poly (lactic acid)s (L -PLAs) and d-lactic (D-PLAs) with major monomer unit fraction down to 85% were synthesized from mixtures of l- acids their stereocomplex (SC)- homo-crystallization the melt investigated. The obtained results compared those previously reported for enantiomeric SRCs, l-lactide-rich (l-lactide-co-d-lactide)s d-...

Recent developments in the synthetic degradable polymers have been the subject of significant interest for macromolecular science to both of an environmental and biomedical perspective with dedication towards applications in tissue engineering and drug delivery. The best candidate for degradable polymer is poly (lactic acid) (PLA), which is described as aliphatic polyester [1]. It is produced f...
