هدف از مطالعه پیش رو ارزیابی سمیت سلولی ترکیب دارویی جدید آریا اورال به روشnormal human keratinocyte neutral red uptake (nhk nru assay) می باشد. در این تحقیق از سه ماده تشکیل دهنده این ترکیب یعنی اوژینول، ریوند به همراه اسید سالیسیلیک و سرکه سیب و ترکیب آریا اورال رقت سریال تهیه شد. رقت های مورد استفاده برای ریوند از 004/0 تا 5/8 میلی گرم در میلی لیتر، اوژینول از 003/0 تا 4/6 میلی گرم در میلی ل...
The use of in vitro (fish cell lines) is a cost-effective, very rapid, and informative tool for toxicological assessments. Using the neutral red (NR) assay, we compared acute toxicity (20hEC50) twenty-six chemical substances on rainbow trout gonad line (RTG-2) with their vivo to Barbados Millions Poecilia reticulata (48hLC50, OECD 203) crustacean Daphnia magna (48hEC50, 202). 20hEC50 values obt...
ATP-dependent proton pumps were found in the vesicles of microsomal membrane fractions of maize coleoptiles. Two membrane fractions isolated by density gradient centrifugation were identified by the aid of marker enzymes and electron microscopic analysis. Membrane fraction A largely consisted of vesicles of smooth ER and of the Golgi complex, fraction B predominantly of vesicles of plasmalemma ...

Neutral red (NR) was utilized as an electron mediator in microbial fuel cells consuming glucose to study both its efficiency during electricity generation and its role in altering anaerobic growth and metabolism of Escherichia coli and Actinobacillus succinogenes. A study of chemical fuel cells in which NADH, NR, and ferricyanide were the electron donor, the electronophore, and the electron acc...
Abstract Background The global production of glycerol is increasing year by since the demands biodiesel rising. It benefit for high-yield succinate synthesis due to its high reducing property. A. succinogenes , a succinate-producing candidate, cannot grow on anaerobically, as it needs terminal electron acceptor maintain balance intracellular NADH and NAD + . Microbial fuel cell (MFC) has been w...
in this research we have developed a treatment method for textile wastewater by tio2/sio2-based magnetic nanocomposite. textile wastewater includes a large variety of dyes and chemicals and needs treatments. this manuscript presents a facile method for removing dyes from the textile wastewater by using tio2/sio2-based nanocomposite (fe3o4@sio2/tio2) under uv irradiation. this magnetic nanocompo...
Silver nanoparticles (AgNPs) are among the most widely commercialised engineered nanomaterials, because of their antimicrobial properties. They are already commonly used in medical devices, household products and industry. Concerns have been raised about potential adverse health effects due to increasing dispersion of AgNPs in the environment. The present study examined the cytotoxic effects of...
In this research, metabolic fixation of CO2 by growing cells of C. acetobutylicum cultivated with electrochemical reducing power was tested on the basis of the metabolites production and genes expression. In cyclic voltammetry, electrochemical oxidation and reduction reaction of neutral red (NR) immobilized in intact cells of C. acetobutylicum was stationarily repeated like the soluble one in t...
The unicellular red alga Cyanidioschyzon merolae is a model organism for studying the basic biology of photosynthetic organisms. The C. merolae cell is composed of an extremely simple set of organelles. The genome is completely sequenced. Gene targeting and a heat-shock inducible gene expression system has been recently established. However, a conditional gene knockdown system has not been esta...
