Objective: To investigatethe effects on histocompatibility and biodegradability of bioabsorbablepolylacticacid (PLA) gelin rats. Methods: Longitudinal incision of 30 mm was made along the spine, and subcutaneous tissues were separated bluntly to make four subcutaneous pouches, and PLA gel of different molecular weight (5, 10 and 20 kD) was implanted into the pouches. 4, 7, 11 and 14 weeks after...
An exclusive-OR transform of input variables significantly reduces the size of the PLA implementation for adder and comparator circuits. For n bit adder circuits, the size of PLA for transformed functions is O(n2). In comparison, when the complete truth-table of an adder is minimized, the PLA size will be O(2n+2). Similarly, for an n bit comparator, the size of the PLA is reduced from O(2n+1) t...
Background: Innovative bioactive films incorporated with antimicrobial agents have been recently developed for food preservation. The aim of this study was to evaluate antibacterial activity of Polylactic Acid (PLA) films incorporated with Ziziphora clinopodioides Essential Oil (ZEO) and Ethanolic Propolis Extract (EPE) against some common food-borne pathogens. Methods: The volatile chemical...
هدف از این پژوهش، تقویت خواص بیوپلیمر پلی لاکتیک اسید (PLA) با استفاده از نانوفیبر سلولز (CNF) و افزایش کارایی آن در بستهبندی مواد غذایی میباشد. به منظور بهبود سازگاری و قابلیت اختلاط با پلیمر، CNF با اسید اولئیک وارد واکنش شده و اصلاح گردید. در ادامه، نانوفیبر سلولز اصلاح شده (MCNF)، با استفاده از روش قالبریزی (در سه غلظت 4، 8 و 12 درصد وزن بیوپلیمر) به ترکیب فیلم PLA اضافه شده و تأثیر آن ب...
OBJECTIVE To evaluate short and long term effects of giving nebulised budesonide early in respiratory syncytial viral (RSV) bronchiolitis. DESIGN A multicentre randomised double blind placebo controlled trial. SUBJECTS Infants admitted to hospital with their first episode of RSV positive bronchiolitis. INTERVENTION Randomisation to receive either 1 mg of nebulised budesonide (Bud) or plac...
Introduction: The venom of Jellyfish venom contains a variety of bioactive proteins that can be studied for vaccine application. Poly-Lactic Acid is a biodegradable polymer that is used in vaccine systems. The aim of this study was to encapsulate the C-CfTX1-STxB protein into PLA-PEG-PLA three-block copolymer and its immunogenicity study in mice. Materials and Methods: After purification, the p...
This paper focuses on the crystalline structure of injection moulding grade poly(lactic acid) (PLA) and the effect of crystalline structure on the processing. The research is induced by the significant differences in crystallinity of the pure PLA resin, and the injection moulded product, and thus the reprocessing of PLA products. 2 mm thick PLA sheets were injection moulded and re-crystallized ...
BACKGROUND There are many combinations of treatments for pyogenic liver abscess (PLA). Different treatments are indicated for different clinical courses of PLA. AIMS To realize the current prevalence, clinical course, trend of treatment, and prognosis of pyogenic liver abscess (PLA) in Taiwan. METHODS We retrospectively reviewed the medical records of 126 patients with PLA. We divided them ...
BACKGROUND AND PURPOSE Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors modulating metabolic and inflammatory responses of phagocytes to stimuli such as fatty acids and their metabolites. We studied the role of PPARs in macrophages exposed to low-density lipoprotein (LDL) modified by secretory phospholipase A(2) (PLA). METHODS AND RESULTS By analy...
BACKGROUND The neural mechanism of posterior left atrium (PLA) for genesis of atrial fibrillation has not been completely elucidated. We sought to assess the contribution of PLA denervation on atrial fibrillation (AF) inducibility and atrial remodeling. METHODS AND RESULTS After left thoracotomy in anesthetized dogs (n = 32), electrode catheters were attached to the PLA, left atrial roof, lef...
