فرضیه: در بین نانوساختارها، نانوالیاف و نانوذرات به دلیل داشتن سطح ویژه زیاد و زیستسازگاری عالی کارایی چشمگیری در مهندسی بافت و رهایش کنترلشده دارو دارند.روشها: در این پژوهش، تولید داربستهای نانولیفی از پلیلاکتیک اسید (PLA)، ژلاتین (Gel) و گرافن (G) بهمنظور ارزیابی کاربرد آنها در مهندسی بافت استخوان بررسی شده است. بهکارگیری ترکیب پلیمر طبیعی ژلاتین به همراه پلیمر سنتزی PLA به استفاده هم...
This study was conducted to determine the effects of dietary supplementation with phenyllactic acid (PLA) on growth performance, intestinal microbiota, relative organ weight, blood characteristics, and meat quality in broilers. A total of 500 male broilers (BW = 46.3 g) were randomly allotted into 1 of the following 5 dietary treatments: 1) basal diet (CON), 2) basal diet + 44 mg/kg of avilamyc...
Enteropathogenic yersiniae (Yersinia pseudotuberculosis and Yersinia enterocolitica) typically cause chronic disease as opposed to the closely related Yersinia pestis, the causative agent of bubonic plague. It is established that this difference reflects, in part, carriage by Y. pestis of a unique 9.6-kb pesticin or Pst plasmid (pPCP) encoding plasminogen activator (Pla) rather than distinction...
Purpose. Somatosensory (SSA) and pharyngolaryngeal auras (PLA) may suggest an extratemporal onset (e.g., insula, second somatosensory area). We sought to determine the prognostic significance of SSA and PLA in temporal lobe epilepsy (TLE) patients undergoing epilepsy surgery. Methods. Retrospective review of all patients operated for refractory TLE at our institution between January 1980 and Ju...
The goal of this study is to explore a new strategy to improve the mechanical and hydrophobic properties of bacterial cellulose (BC) mats. The present work is the first to report the preparation of in situ self-assembled BC nanocomposites using electrospun hydrophobic poly(lactic acid) (PLA) or PLA/lipids (PLA/Lip) nanofiber mats as foundation for BC nanofiber growth. Adding electrospun PLA mat...
Scaffolds encourage the new tissue formation through biological substitution of damaged or lost tissues. Therefore, scaffold characteristics become more important and should be precisely controlled. Production scaffolds using a three dimensional (3d) printer appears as promising method in terms enabling homogeneous pore distribution uniform size arrangement. In this study, polylactic acid (PLA)...
Polylactic acid (PLA) has found widespread use in plastics and in biomedical applications due to its biodegradability into natural benign products. However, PLA-based materials remain limited in usefulness due to difficulty of incorporating functional groups into the polymer backbone. In this paper, we report a strategy for PLA functionalization that establishes the preparation of highly deriva...
این مقاله چندسازه پلی لاکتیک اسید (PLA)/ الیاف کاه گندم ساخته شده بوسیله اکسترودر دو مارپیچ و قالبگیری تحت فشار مورد بررسی قرار گرفت. برای سازگاری بهتر بین دو فاز الیاف کاه گندم بوسیله تری اتوکسی متیل سیلان مورد تیمار قرار گرفتند. ویژگیهای فیزیکی، ویژگیهای کششی چندسازهها مورد تجزیه و تحلیل قرار گرفت. همچنین اثر الیاف کاه گندم بر روی ویژگی-های گرمایی PLA در آزمون گرماسنج پوبشی تفاضلی مورد بر...
A polarization-selective uncooled infrared (IR) sensor was developed based on an asymmetric twodimensional plasmonic absorber (2-D PLA). The 2-D PLA has an Au-based 2-D periodic dimple structure, where photons can be manipulated by spoof surface plasmon polaritons. Asymmetry was introduced into the 2-D PLA to realize a polarization selective function. Numerical investigations demonstrate that a...
The purpose was to determine the effect of carbohydrate (CHO) mouth rinse on maximal voluntary contraction (MVC) and neuromuscular output in a fatigued state. It was hypothesized that CHO mouth rinse would potentiate torque output in a fatigued state. In a double-blind, cross-over design, 12 competitive male athletes (9 rowers, 1 cyclist, 1 runner and 1 volleyball player) initially performed 3 ...
