BACKGROUND Human colonic contents and many colonic microbes produce considerable amounts of acetaldehyde from ethanol in vitro. AIMS To examine in piglets if acetaldehyde is produced in the colon also in vivo, and if so, what is the fate of intracolonically formed acetaldehyde. ANIMALS Seventeen native, non-fasted female piglets (20-25 kg) were used. METHODS Six piglets received either 1....

Polystyrene (PS) opal and titania (TiO2) inverse opal films were fabricated by the self-assembly colloidal crystal template technique. Based on Bragg’s law, these sensors were used to detect the different concentrations of ethanol solution. The results indicated that TiO2 inverse opal films were advantageous over PS opal film for detecting the ethanol concentration. TiO2 inverse opal films sint...

The solubilities of four surfactants, sodium bis-2-ethylhexyl sulfosuccinate (AOT), cetyltrimethylammonium chloride, didodecyldimethylammonium bromide, and n-dodecyltrimethylammonium chloride in liquid refrigerant 1,1,1,2-tetrafluoroethane (R134a) modified with methanol, ethanol, and 2-propanol were measured. The measurements were performed under 25 and 50 bar at 25 C. The solubility of AOT was...

The electrochemical oxidation on platinum and platinum rhodium bimetallic electrodes was studied by Differential Electrochemical Mass Spectrometry for several ethanol concentrations in solution. It is found that increasing the ethanol concentration the production of the partially oxidized products (acetaldehyde) increases as the concentration increases. On the other hand, addition of 25% at. of...

The fluorescence spectra of the title compound have been measured in ethanol and in aqueous solutions of different p H . In ethanol the neutral molecule's fluorescence (at 360 nm) is observed, whereas in aqueous solutions emission occurs from the anion (at 428 nm) and from a " tautomer ic " species (at 460 nm), but not from the neutral molecule. An aqueous solution at p H 3, which contains abou...

Compound A which is the starting compound was prepared by the reaction between 4Chlorobenzaldehyde and 4-Bromoacetophenone in the presence of Ethanol. Compound A was Preparedby4Chlorobenzaldehyde that dissolved in ethanol in presence of Sodium hydroxide with 4-Bromoacetophenone. B was prepared through addition of 4-Bromoacetophenone that dissolved in Ethanolwith4-(Dimethyl amino) Benzaldehyde b...

AIMS The principal aim of this study was to investigate the oxidative effects of chronic ethanol consumption on the functions of the heart and the kidney and the possible modification of this effect by folic acid supplementation. Moreover, in order to find whether this oxidative profile affects cardiovascular function, parameters such as heart rate and glomerular filtration rate were also asses...

Ethanol can initiate Pt nanoparticles to catalyze the chemiluminescent reaction of alkaline lucigenin solution, leading to a visible light emission with autocatalytic property.

The aim of the present study was to evaluate the chronic toxicity of ethanol low blood levels in malnourished rats. Female Wistar rats (220 g) were subjected to either an ad libitum diet (W, well-nourished, n=10) or food restriction (M, malnourished, n=10). Water (WW and MW) or ethanol solution (W5% and M5%) was offered to half of each nutritional group (n=5) as the only fluid source. The treat...

HIROSE, T., HIGASHI, R., IKEDA, H., TAMIIRA, K. and Suzuxi, T. Effect of Ethanol on Adrenaline anal Noradrenaline Secretion of the Adrenal Glandin the Dog. Tohoku J. exp. Med., 1973, 109 (1), 85-88 Conscious dogs were infused intravenously with ethanol solution in a dose of 0.7-1.0 g/kg. Before and after the ethanol infusion, the adrenal venous blood samples were collected and analyzed for adre...
