1. Ethanol affects the absorption and tissue distribution of orally administered antigens in mice
The aim of this work was to evaluate the effects of ethanol on the adsorption and tissue distribution of orally administered antigens in mice. Results showed that ethanol reduced the level of anti-ovalbumin IgA antibodies in intestinal fluid for the mice treated orally with a palmitoyl-ovalbumin conjugate. Ethanol was administered intragastrically to mice at

2. Pentaclethra macroloba tannins fractions active against methicillin-resistant staphylococcal and Gram-negative strains showing selective toxicity
The ethanol extract of the vegetal species Pentaclethra macroloba (Willd.) Kuntze, Fabaceae, was fractioned and the antibacterial activity was determined. The active ethyl acetate (ea) fraction showed activity against Gram-positive (Staphylococcus spp. and Enterococcus spp.) and Gram-negative (Pseudomonas aeruginosa, Acinetobacter spp. and Klebsiella pneumon

3. Efeitos de terpenos nas membranas de estrato córneo estudados por ressonância paramagnética eletrônica / Effects of terpenes on the stratum corneum membranes studied by electron paramagnetic resonance
The interaction of the skin penetration enhancers DL-menthol, -terpineol, 1,8-cineole and (+)-limonene with membranes of the uppermost skin layer, the stratum corneum (SC) and with multilamellar vesicles from 1,2-dipalmitoyl-sn-glycero-3-phosphaticylcholine (DPPC)is investigated by electron paramagnetic resonance (EPR) spectroscopy using spin-labeled

4. ELETROOXIDAÇÕES DE ACETALDEÍDO COMUM E ETANOL ISOTOPICAMENTE MARCADO (H3 13C12CH2OH) EM SUPERFÍCIE DE PLATINA ACOMPANHADAS POR FTIRS in situ / Electrooxidation of acetaldehyde common and ethanol Isotope-labeled compounds (H3 13C_12CH2OH) in surface accompanied by platinum FTIRS in situ.
Este trabalho trata das reações de eletrooxidações de acetaldeído comum e etanol isotopicamente marcado, ambas reações em superfície de platina policristalina em meio de ácido perclórico, HClO4, 0,1 Mol L-1, com a utilização de técnicas eletroquímicas convencionais e espectroscopia (FTIRS in situ). Para o acetaldeído, essa reação foi estuda

6. Ethanol Extraction Requirement for Purification of Protein Labeled with [3H]Leucine in Aquatic Bacterial Production Studies †
The trichloroacetic acid (TCA)-insoluble fraction of water column bacteria labeled with [3H]leucine contained an ethanol-soluble fraction accounting for up to 44% of the label. A component of the ethanol-soluble fraction is [3H]leucine. Labeled-protein purification requires an ethanol wash step. Cold TCA can replace hot TCA for precipitation of labeled prote

7. Effects of ethanol on alanine metabolism in perfused mouse liver studied by 13C NMR.
Time courses of 13C labeling from alanine and ethanol in perfused mouse livers have been followed by NMR. The enrichment at specific carbons of glucose, glutamate, glutamine, aspartate, acetate, acetoacetate, beta-hydroxybutyrate, and lactate has been measured. The specific labeling of glutamate in the presence of labeled alanine and labeled or unlabeled eth

8. Ethanol disordering of spin-labeled mouse brain membranes: correlation with genetically determined ethanol sensitivity of mice.
Disordering of brain and erythrocyte membranes by ethanol in vitro was measured by ESR using 5-doxylstearic acid as spin label. Synaptosomal plasma membranes and erythrocyte membranes were isolated from two lines of mice developed, by selective breeding, for differential sensitivity to hypnotic effects of ethanol. Membranes taken from alcohol-sensitive "long

9. Ethanol regulates calcium channels in clonal neural cells.
The acute and long-term effects of ethanol on voltage-dependent Ca channel function were studied in PC12, a clonal cell line of neural crest origin. Acute exposure to ethanol produced a concentration-dependent decrease in depolarization-evoked 45Ca2+ uptake, while prolonged (2-10 days) exposure led to a reciprocal increase in 45Ca2+ uptake and in the number

10. Metabolism of Transpired Ethanol by Eastern Cottonwood (Populus deltoides Bartr.).
Ethanol has previously been shown to be present in the xylem sap of flooded and nonflooded trees. Because of the constitutive presence of alcohol dehydrogenase in the mature leaves of woody plants, we hypothesized that the leaves and shoots of trees had the ability to metabolize ethanol supplied by the transpiration stream. 1-[14C]Ethanol was supplied to exc

11. Ethanol-induced activation of adenine nucleotide turnover. Evidence for a role of acetate.
Consumption of alcohol causes hyperuricemia by decreasing urate excretion and increasing its production. Our previous studies indicate that ethanol administration increases uric acid production by increasing ATP degradation to uric acid precursors. To test the hypothesis that ethanol-induced increased urate production results from acetate metabolism and enha

12. Membrane Fluidity Adjustments in Ethanol-Stressed Oenococcus oeni Cells
The effect of ethanol on the cytoplasmic membrane of Oenococcus oeni cells and the role of membrane changes in the acquired tolerance to ethanol were investigated. Membrane tolerance to ethanol was defined as the resistance to ethanol-induced leakage of preloaded carboxyfluorescein (cF) from cells. To probe the fluidity of the cytoplasmic membrane, intact ce
