In this study, silver nanoparticles effects on the sterilization of different sources explants (young leaves, young flower stalks and buds) Gerbera as well in vitro morphogenesis their growth were investigated. The sterilized cut transversally (1 mm) with stalk, square (0.5 × 0.5 cm) for leaf sample, longitudinally flowers (removed petals) cultured MS medium; then, (contamination-free or no bro...
The glucagon-like peptide 1 (GLP-1) analogue Exendin-4 (Ex-4) could perform anti-oxidative effects against oxidative damage both in vitro and in vivo. However, little was known about the direct protection of Exendin-4 on RPE cells against oxidative stress and its underlying mechanism. The present study examined the protective effects of Exendin-4 on RPE cells against H2O2 treatment in vitro and...
هدف: بررسی اثر آنتی بیوتیک سیپروفلوکساسین بر نوتروفیلها ومنوسیتهای بیماران مبتلا به عفونت دستگاه ادراری ناشی از اشرشیا کولی پیش و پس از مصرف آنتی بیوتیک در تولید نیتریک اکساید (no) و پراکسید هیدروژن (2o2h) از این سلولها در محیط کشت. مواد و روشها: تعداد 45 بیمار خانم مبتلا به عفونت ادراری ناشی از اشرشیا کولی بین سنین 18 تا 50 سال انتخاب و سلولهای منوسیت و نوتروفیل این بیماران در دو مرحله، یکبار ...
Background: Exposure to ionizing radiation results in genotoxicity and the unrepaired lesions in cellular DNA results in cell cycle arrest, reproductive death, interphase death, division delay, chromosome aberrations, mutations, etc. leading to the intensive destruction of cells and violation of their proliferative capacity there by adversely affecting the mammalian system. Since ionizing radia...
promethazine hydrochloride, a 5-ht3 antagonist is a powerful antiemetic drug with an oral bioavailability of 25% due to extensive hepatic first pass metabolism and is extremely bitter in taste. to overcome the above draw backs, the present study was carried out to formulate and evaluate fast dissolving taste masked wafers of promethazine hydrochloride for sublingual administration. taste maskin...
Diabetes mellitus is a frequent cause for chronic, difficult-to-treat wounds. New therapies for diabetic wounds are urgently needed and in-vitro or ex-vivo test systems are essential for the initial identification of new active molecules. The aim of this study is to compare in-vitro and ex-vivo test systems for their usability for early drug screening and to investigate the efficacy of a birch ...
