The fatty acid desaturation-elongation ability of human T-lymphocytes during blastic transformation was determined both by gas-liquid chromatography and incubation with radiolabeled precursors. Human peripheral blood mononuclear cells (PBMC) were activated with phytohemagglutinin (PHA) and cultured in media supplemented with different fatty acids (18:0,(More)
The time-course changes in fatty acid composition of human T-lymphocytes during blastic transformation were analysed, as well as the variations in membrane fluidity determined by fluorescence polarization of 1,6-diphenyl-1,3,5-hexatriene (DPH), using a fluorescence-activated cell sorter. The more important changes observed, in activated relative to(More)
Epidemiological and experimental data suggest that fatty acids may modulate the growth of tumor cells. We have analyzed the effect of different types of fatty acids, bound to serum proteins in physiological conditions, on the lipid composition and growth of human neoplastic B and T-cell lines and compared their effect on normal lymphocyte proliferation.(More)
The objective of this study was to investigate, using a pulse-chase technique, the different incorporation of (1-(14)C) n -9, n -6 and n 3 fatty acids into hepatoma lipids and their secretion to the culture medium. Docosahexaenoic acid (DHA) accumulated preferentially into the triacylglycerol while arachidonic acid (AA) did into the phospholipid fraction.(More)
7-Chloro-3-[1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)ethoxy-methyl] benzo[b]thiophene (sertaconazole, FI-7045, CAS 99592-32-2) is a new antimycotic which, in experimental infection studies, proved to possess potent antifungal activity. In a randomized, parallel, double-blind trial, the activity of sertaconazole cream was studied in 20 patients suffering(More)
Time Series Forecasting (TSF) is a key tool to support decision making, for instance by producing better estimates to be used when planning production resources. Artificial Neural Networks (ANN) are innate candidates for TSF due to advantages such as nonlinear learning and noise tolerance. The search for the best ANN is a complex task that strongly affects(More)
The uptake of polyunsaturated fatty acids by rat hepatoma cells and fetal hepatocytes has been studied using albumin and alpha-fetoprotein (AFP) as carrier proteins. Both types of cells took up linoleic (18:2(n-6)) and linolenic (18:3(n-3)) fatty acids at the same rate when they were added complexed either to albumin or AFP at a 1:1 molar ratio. At 37(More)
Freshly isolated fetal hepatocytes transformed 4.3, 8.5 and 19.2 pmol/min/10(6) cells of stearic, linoleic and alpha-linolenic acids, respectively, complexed to albumin or alpha-fetoprotein (AFP), to more unsaturated derivatives. Thus, fetal hepatocytes displayed high elongase and delta9, delta6, delta5-desaturase activities, as well as an ability to(More)
BACKGROUND Prognostic biomarkers are needed to improve the management of the heart failure (HF) epidemic, being the brain natriuretic peptides the most valuable. Here we evaluate 3 biomarkers, high sensitivity troponin T (hs-TnT), galectin-3 (Gal-3) and C-terminal propeptide of type I procollagen (CICP), compare them with a recently described new candidate(More)
Morris 7777 rat hepatoma cells in culture possess high delta 6 and delta 5 desaturase activities over linolenic acid added to the medium as albumin or alpha-fetoprotein complexes. After 2 hours incubation with [1-14C] linolenic acid (7 microM), around 40% of the radioactivity was recovered in other polyene fatty acids, mainly pentaenes. After 24 hours(More)
