A new composite poly(caprolactone) (PCL) and poly(acrylic acid) (PAA) (PCL:PAA 1:5) scaffold was synthesized via dispersion of PCL particles into a PAA network. Silica microspheres (Si) (2–12 μm) were then prepared by a lyophilized micro-emulsion/sol-gel (Emugel) system using varying weight ratios. The model drug ciprofloxacin (CFX) was used for in situ incorporation into the scaffold. The phys...
بهره وری از سرریز های پلکانی، به علت هزینهی ساخت پایین و بازدهی بالای آنها بطور فزاینده ای رو به افزایش است. از این رو، تحقیقات نیز در این زمینه با رشد و توجه زیادی از سوی مهندسین سد همراه بوده، ولی اغلب این مطالعات در زمینهی سرریز های پلکانی با ارتفاع پلهی یکنواخت می باشد، در حالی که ارتفاع پلهی غیر یکنواخت نیز می تواند در بعضی حالات به عنوان یک گزینه مطرح گردد. در این تحقیق از یک نمونهی ...
In this work, biopolymer-based nanocomposites with antimicrobial properties were prepared via melt-compounding. In particular, graphene nanoplatelets (GnPs) as fillers and an antibiotic, i.e., ciprofloxacin (CFX), as biocide were incorporated in a commercial biodegradable polymer blend of poly(lactic acid) (PLA) and a copolyester (BioFlex®). The prepared materials were characterized by scanning...
objective(s):cefixime (cfx), is a semi-synthetic third-generation oral cephalosporin antibiotic that is prescribed for the treatment of susceptible infections. there are some procedures for the determination of cfx in pharmaceutical formulations and biological samples. herein a spectrofluorimetric method was proposed for cfx determination based on the fluorescence quenching of terbium-danofloxa...
Ciprofloxacin (CFX) is an effective and relatively safe antimicrobial used in a variety of human infections. However, adverse drug reactions and positive results in genotoxic tests are reported. In order to understand the possible pathophysiological mechanisms of the toxic effects informed for CFX, lipid hydroperoxides (LOOH) -oxidative mediators of peroxidation- were quantified in liver and ki...
Di- and tripeptides, as well as peptidomimetic drugs such as cephalexin (CFX), are absorbed by enterocytes via the oligopeptide transporter PepT1. We recently showed that the alpha(2)-adrenergic agonist clonidine increases CFX absorption in anaesthetized rats. Herein, we investigated whether alpha(2)-adrenergic receptors can directly affect PepT1 activity in a clone of the differentiated human ...
بخش اصلی بدنه فشار زیردریایی متشکل از بخش استوانه‌ای تقویت شده است که عموما توسط دیواره عرضی (بالکهد) به چند بخش تقسیم شده است. در این مقاله با در نظر گرفتن بدنه فشار زیردریایی به صورت پوسته استوانه‌ای تقویت شده به بررسی اثر وجود بالکهد در ارتعاش آزاد آن پرداخته شده است. برای این منظور ارتعاش آزاد یک پوسته استوانه‌ای تقویت شده توسط نرم افزارAnsys تحلیل شده و نتایج آن با نتایج تجربی و تحلیلی...
The synthesis of a novel functional biomaterial for wound healing treatment was carried out by adopting a free-radical grafting procedure in aqueous media. With this aim, ciprofloxacin (CFX) was covalently incorporated into collagen (T1C) chains employing an ascorbic acid/hydrogen peroxide redox pair as biocompatible initiator system. The covalent insertion of CFX in the polymeric chains was co...
Dietary proteins are mostly absorbed as di- and tripeptides by the intestinal proton-dependent transporter PepT1. We have examined the effects of leptin on PepT1 function in rat jejunum and in monolayers of the human enterocyte-like 2 cell Caco-2. Leptin is produced by the stomach and secreted in the gut lumen. We show here that PepT1 and leptin receptors are expressed in Caco-2 and rat intesti...
