Microwave irradiation was used to synthesize PEG-PCL and PEG-PLA copolymers that are composed of biodegradable polymers including PEG, PLA, and PCL. These copolymers were used for loading docetaxel in nanoparticles. Single emulsion-solvent evaporation technique was applied for preparing the PEG-PLA and PEG-PCL mixed nanoparticles (micelles and polymersomes) with different proportions, including...
Blends of soy protein (SP) and a semicrystalline polylactide (PLA) were prepared using a twin-screw extruder. The melt rheology, phase morphology, mechanical properties, water resistance, and thermal and dynamic mechanical properties were investigated on specimens prepared by injection molding of these blends. The melt flowability of soy-based plastics was improved through blending with PLA. Sc...
شکل گیری اندودرم قطعی (definitive endoderm) یکی از مراحل مهم در تکوین اندام های مشتق از اندودرم مانند پانکراس و کبد در مهره داران می باشد. به همین دلیل، تولید اندودرم به عنوان منبعی برای تولید انواع سلول های کارآمد در درمان بیماری های مرتبط با این اندام ها از جمله دیابت و بیماری های کبدی از اهمیت بالایی برخوردار است. بنابراین، با توجه به بحث سلول درمانی، معرفی روش هایی تعریف شده تر، کاراتر و کم...
یکی از مشکلات اصلی استفاده از پلیمرهای زیست‌تخریب‌ناپذیر باقی‌ماندن آن در چرخه زیستی پس از مصرف است. توسعه پلاستیک‌های زیست‌تخریب‌پذیر راه حل خوبی برای حل این مشکل است. اختلاط پلیمر پلی‌لاکتیک اسید با پلیمرهای یست‌تخریب‌ناپذیر می‌تواند روشی کاربردی و اقتصادی برای اصلاح خواص زیست‌تخریب‌پذیری پلیمرهای تجزیه‌ناپذیر باشد. در این پژوهش، زیست تخریب‌پذیری فیلم‌های آمیخته از پلی‌اتیلن پ...
Present study shows that non-covalent interaction of kaouthiotoxin (KTX) with their respective pohospholipase A(2) (PLA(2)) from the venom of N. kaouthia displayed marked synergism to exert cytotoxicity without altering the biochemical properties of PLA(2). For example, although NK-PLA(2) or KTX alone did not induce appreciable hemolysis of washed human erythrocytes; however, the hemolytic pote...
OBJECTIVE The purpose of this study was to develop an active targeting strategy to improve the therapeutic antitumor efficacy of oridonin (ORI), the main active ingredient in the medicinal herb Rabdosia rubescens. METHODS A modified spontaneous emulsification solvent diffusion method was used to prepare the ORI-loaded atactic poly(D,L-lactic acid) nanoparticles (ORI-PLA-NPs). Surface cross-li...
Phospholipase A(2) (PLA(2)) catalyses the hydrolysis of phospholipids into lysophospholipids and free fatty acids. Physiological studies have indicated that PLA(2) is involved in stomatal movement. However, genetic evidence of a role of PLA(2) in guard cell signalling has not yet been reported. To identify PLA(2) gene(s) that is (are) involved in light-induced stomatal opening, stomatal movemen...
Ninety weanling pigs in Exp. 1 (6.27 +/- 0.73 kg; 21 d of age) and 96 growing pigs in Exp. 2 (21.73 kg +/- 1.29 kg; 56 d of age) were used in two 42-d experiments to evaluate the effect of phenyllactic acid (PLA) on growth performance, apparent total tract digestibility (ATTD) of DM and N, fecal pH value, microbial shedding, and blood profiles. In Exp. 1, the 3 dietary treatments were 1) negati...
Subject codes: [108] Other myocardial biology [145] Genetically altered mice, [151] Ischemic biology-basic studies In November 2013, the average time from submission to first decision for all original research papers submitted to Circulation Research was 14.6 days. ABSTRACT Rationale: Recent evidence indicates that the biological effects of secretory phospholipase A 2 s (sPLA 2) cannot be fully...
background: autoxidation is considered to be the main route of edible oil deterioration, which produces undesirable odors and flavors (attributed to primary and secondary products of unsaturated fatty acids) during storage and heating. objective: antioxidant activities of zataria multiflora (zmeo) and bunium persicum (bpeo) essential oils (eos) in linseed oil (containing higher ω-3 in vegetable...
