background: acute infectious diarrhea is one of the most important causes of morbidity and mortality worldwide. objectives: the objective of this study was to characterize antimicrobial resistant diarrheagenic escherichia coli strains isolated from diarrheic children in tehran, ir iran. patients and methods: in total, 550 stool samples from diarrheic pediatric patients, aged less than 60 months...
The objective of this study was to investigate intestinal nutrient transporter and enzyme mRNA in broilers selected on corn- and soybean-based (line A) or wheat-based (line B) diets. We investigated the peptide transporter PepT1, 10 amino acid transporters (rBAT, b(o,+)AT, ATB(o,+), CAT1, CAT2, LAT1, y(+)LAT1, y(+)LAT2, B(o)AT, and EAAT3), 4 sugar transporters (SGLT1, SGLT5, GLUT5, and GLUT2), ...
The yolk sac membrane plays a major role in the transport of nutrients from the yolk contents to the chick embryo. We examined whether the yolk sac membrane expresses genes for nutrient digestion, enzymes, and nutrient transporters. We evaluated relative mRNA abundance of the digestive enzymes aminopeptidase N (APN) and sucrase-isomaltase (SI); the nutrient transporters oligopeptide transporter...
L-arginine transport is crucial for macrophage activation because it supplies substrate for the key enzymes nitric oxide synthase 2 and arginase I. These enzymes participate in classic and alternative activation of macrophages, respectively. Classic activation of macrophages is induced by type I cytokines, and alternative activation is induced by type II cytokines. The granulocyte macrophage co...

سابقه و هدف: کلبسیلا پنومونیه از شایعترین باکتریهای گرممنفی در ایجاد عفونتهای بیمارستانی به ویژه عفونتهای دستگاه ادراری است که در چند سال اخیر به دلیل مصرف بیرویه آنتیبیوتیکها در درمان بیماریهای انسانی و دامی نسبت به اکثر آنتیبیوتیکها مقاوم شدهاست. هدف از این مطالعه، تعیین الگوی مقاومت آنتیبیوتیکی در شایعترین تیپهای کپسولی این باکتری در شهرستان زرینشهر اصفهان بود. مواد و روش کار...
Karrikins are active components of smoke that can promote seed germination and regulate seedling morphogenesis. However, the role karrikins as alleviators abiotic stress remains largely elusive. In this study, we examined whether exogenous application karrikin1 (KAR1) might improve drought tolerance in creeping bentgrass (Agrostis stolonifera cv. PennA4), investigated underlying mechanism. We f...
