The adsorption and desorption efficiencies on flavonoids and polyphenols from Eucommia ulmoides leaves by different resins were investigated, and the most suitable resin for preparation of Eucommia ulmoides leaves antioxidant was chosen. Then the crude extract of Eucommia ulmoides leaves was adsorbed by resin, and the resin was eluted by 20%, 40%, 60% and 80% (in volume) ethanol elution solutio...

BACKGROUND Postweaning social isolation in rats produces profound and long-lasting cognitive and behavioral deficits in adult animals. Importantly, this housing manipulation alters sensitivity to a number of drugs of abuse including ethanol. However, most studies with ethanol have utilized continuous or limited home-cage access to examine interactions between juvenile social experience and drin...

Denatured fuel ethanol is the feedstock used to make different types of high ethanol content motor fuels. Before it can be used, the amount of ethanol and methanol must be measured to assure product quality. ASTM method D5501-09 uses high resolution gas chromatography to perform this analysis. In this paper, the Agilent 7890A GC system was configured to run D5501-09. Excellent system performanc...

AIM The examination of the possibility of ethanol oxidation in the brain in vivo and the evaluation of the enzyme catalase in this process. METHODS We anesthetized rats and perfused the brain with ethanol solutions through the lateral ventricle and collected the perfusate from the Cisterna magna. We determined ethanol and acetaldehyde in the perfusate by gas chromatography. RESULTS It was f...

The present study was designed to evaluate ethanol drinking behaviour in Sardinian alcohol-preferring (sP) and Sardinian alcohol-non-preferring (sNP) rats in the presence of different ethanol concentrations. Ethanol intake was tested under the two-bottle, free-choice regimen and continuous access schedule. Ethanol-naive sP and sNP rats were initially given ethanol solution at the standard, cons...

An extraordinary high-speed synthesis of gold nanoparticles (AuNPs) was discovered by synthesizing the AuNPs in ethanol-water mixtures using a solution plasma process (SPP). The influence of the ethanol mole fraction (χethanol) in the ethanol-water mixtures on the reduction rate of gold chloride ions to AuNPs under the SPP system was studied. The results indicated that the reaction rate of the ...

the aim of this work was to develop and evaluate a minoxidil foamable emu oil emulsion with the purpose of improving minoxidil permeation into the skin, increasing hair growth , reducing skin irritation, and increasing consumer compliance. minoxidil was dissolved in a solvent system comprising ethanol: glycerin: lactic acid: water (10:20:5:65). the foamable emulsion was prepared by mixing the o...
