Degradation of phosphatidylethanol counteracts the apparent phospholipase D-mediated formation in heart and other organs.
2003
Phosphatidylalcohols, such as phosphatidylethanol (PEth), are formed from phosphatidylcholine in the presence of a primary alcohol (e.g., ethanol). This 'transphosphatidylation' reaction is used as specific phospholipase D (PLD) assay. Accumulation of PEth in tissues is recognized as a reliable measure of PLD activity, as PEth is allegedly metabolically stable. The general validity of this assumption was reinvestigated in isolated rat heart, small intestine and brain slices. The half-times of 3H-PEth degradation (labelled with 3H-myristic acid and preformed by ethanol exposure for 30 min) were about 1 h in heart and small intestine, but 17 h in brain. As the formation of PEth is superimpose…
Responses to eccentric rotation in two space-bound subjects
1993
Two subjects were rotated eccentrically in the manner described previously. In contrast to a normal control group, settings of a luminous line to the subjective vertical were almost unrelated to the gravitoinertial vector before, and totally so shortly after, space flight. Only 3 days postflight did a clear relation to the gravitoinertial vector re-establish itself in the one subject who actually flew. The correspondence became normal 5 days after the flight. Since there were no clinical abnormalities evident in the subjects, it is suggested that both subjects suppressed their vestibular information, presumably as an effect of vestibular deconditioning training before the flight. In additio…

Innovative Compact Solar Air Conditioner based on Fixed and Cooled Adsorption Beds and Wet Heat Exchangers
2014
Abstract In this work, a new all-in-one compact solar air conditioner concept is presented. The system is mainly based on a new DEC process which utilises fixed and cooled adsorption beds operating in a batch process and two wet heat exchangers. The proposed innovative adsorption bed is a fin and tube heat exchanger commonly used in the air conditioning sector, wherein the spaces between the fins are filled with silica gel grains. The main feature of this component is to allow simultaneous dehumidification and cooling of air. Furthermore, since the component hosts a considerable amount of adsorption material, solar energy can be efficiently stored in the desiccant media in terms of accumula…

Hierarchizing Energy Saving Strategies in Wine Industry by Advanced Modelling of Chilling Units Operation
2019
Wineries are energy intensive industries and in order to make the production process more sustainable, solutions for an efficient use of energy should be implemented. Large surveys conducted in the wineries sector have highlighted the importance of performing accurate energy audits and have identified in the installation of efficient cooling/refrigeration systems the most promising solutions in a variety of cases. Unfortunately, the savings achieved by such energy efficient solutions is often calculated by highly simplified approaches, which do not take into consideration the actual operating conditions of the equipment (highly variable on a seasonal and daily basis). In this paper a system…
Isotope removal experiment in JET-ILW in view of T-removal after the 2nd DT campaign at JET
2022
Abstract A sequence of fuel recovery methods was tested in JET, equipped with the ITER-like beryllium main chamber wall and tungsten divertor, to reduce the plasma deuterium concentration to less than 1% in preparation for operation with tritium. This was also a key activity with regard to refining the clean-up strategy to be implemented at the end of the 2nd DT campaign in JET (DTE2) and to assess the tools that are envisaged to mitigate the tritium inventory build-up in ITER. The sequence began with 4 days of main chamber baking at 320 °C, followed by a further 4 days in which Ion Cyclotron Wall Conditioning (ICWC) and Glow Discharge Conditioning (GDC) were applied with hydrogen fuelling,…
Favoriser l'acceptation de légumes chez l'enfant. Comparaison des stratégies d'exposition répétée, d'association flaveur-flaveur et d'association fla…
2012
La consommation de légumes étant inférieure aux recommandations nutritionnelles, et particulièrement chez les enfants, mieux comprendre les facteurs qui favorisent leur acceptation est essentiel. Différentes stratégies visant à favoriser l’acceptation d’aliments sont décrites. Il s’agit de l’exposition répétée (RE), de l’association flaveur-flaveur (AFF) et de l’association flaveur-nutriment (AFN). La présente étude a pour objectifs de comparer l’efficacité de ces trois stratégies, de mesurer la stabilité de leurs effets, et d’expliquer par l’histoire alimentaire de chacun les différences individuelles d’acceptation de légumes. Une purée d’artichaut (légume cible, généralement peu apprécié)…
Effects of energy density on the liking for sweet drinks and on caloric adjustment conditioning after exposure in children
2014
The contribution of energy density from sweet drinks to energy intake in children needs clarification. The objective was to study the influence of energy conditioning on liking and on caloric adjustment after sweet drinks exposure. Children aged 8 to 11 (n=44) were exposed to distinctly flavored sweetened drinks: a high-energy (HE: 150kcal) and a no-energy version (NE: 0kcal). They received either 2 or 7 exposures to each drink during a 4-wk conditioning period; no exposure during a 3-wk stability period; 3 exposures to both drinks, for which the association between the flavor and the energy density was switched, during a 4-wk extinction period. Flavor liking and food intake during the meal…
Ventilatory conditioning by self-stimulation in rats: A pilot study
1994
International audience; This article describes an experimental attempt to condition breathing pattern in rats. In this experiment, a freely moving rat was first rewarded by an electrical stimulation of the medial forebrain bundle whenever inspiratory duration (TI) exceeded 300 ms. A bidirectional control was then used: TIs longer than 400 ms were rewarded, and then TIs shorter than 300 ms were rewarded. The frequency of TIs longer than 300 ms increased when this event was rewarded, further increased when TIs above 400 ms were rewarded, and decreased during reversal conditioning (TI < 300 ms). At the beginning of the experiment, stimulation caused increased arousal and motor activity, but af…
