[...] Pour les raisons énoncées précédemment, il nous a semblé important d'étudier quelles étaient les réactions du champignon lorsqu'il venait en contact avec les substances naturellement présentes à la surface des feuilles, quelle était lat nature de ces substances et leur rôle dans l'établissement de la maladie et aussi comment une fois la maladie établie, le champignon pouvait affecter la nature et la quantité de ces substances qui sont perdues par les feuilles sous l'action de la pluie.

Obesity is considered an underlying risk factor for metabolic disease including cardiovascular disease (CVD) and diabetes. The fractions containing flavonols from apple peel were evaluated for their antioxidant, anti-inflammatory, and hypolipidemic properties using in vitro and in vivo experimental model systems. The fractionated polyphenolics from apple peels showed a strong antioxidant property protecting against heat-induced oxidation of polyunsaturated fatty acids present in fish oil. Apple flavonols (AF), eicosapentaenoic acid (EPA) and the isoquercitrin-EPA ester (QE) significantly reduced serum triacylglycerols and elevated the high density lipoprotein (HDL)-cholesterol compared to the high fat control group. C-reactive protein and interleukin-6 were also reduced compared to the high fat control group and inflammation induced by lipopolysaccharides. Serum adiponectin and interferon-? concentrations were significantly altered by QE treatment. Overall, AF and QE exhibited anti-inflammatory and hypolipidemic effects under in vivo conditions. These beneficial physiological properties and mode of action of AF and QE need to be further investigated.

Cette recherche questionne les usages des interfaces graphiques et tactiles d’un hub Apple conduisant à l’interférence de deux espaces de communication: le premier part d’un dispositif WIMP (d’un Mac, de son système d’exploitation Mac OS X et d’une application tierce) et le second d’un dispositif post-WIMP (d’un iPad, de son système iOS et d’une application intégrée au support). La question porte sur les effets de cette interférence sur les pratiques d’usage. La recherche s’appuie en parallèle et de manière complémentaire sur l’analyse écranique et tactile de ce qui est modélisé et prescrit par les médiatisateurs, et sur l’étude de la manière dont des usagers instrumentent ou non ce qui leur est proposé, en usant d’une certaine marge de liberté et créativité. L’articulation de ces deux niveaux conduit à reconsidérer la question de la médiatisation de schèmes organisateurs d’actions, et de leur régulation en termes de normes d’actions communicationnelles aux niveaux industriels, culturels, comme au niveau plus fondamental de la cognition qui en est à l’origine. La dimension communicationnelle de la recherche tient aux enseignements qu’elle tire de la manière dont, au croisement des approches ergonomiques, psychologiques et cognitives, se déploie la dimension relationnelle des échanges et interactions entre différents acteurs. / AThis research calls into question the use of the graphical and the tactile interfaces of an Apple hub, in the sense that this hub leads to interference between two areas of communication. The first starts from a WIMP device (a Mac, its exploitation system Mac OS X, and a third party application). The second starts from a post-WIMP device (an iPad, its iOS system, and a built-in application). The question at issue bears on the effects of this interference on user practices. In parallel and complementary fashion, the research is based on the analysis of the model, both screen and tactile, envisioned and prescribed by the designers of the devices, as well as on an analysis of the manner in which users actually employ in instrumental fashion (or not) what is offered to them, while using a certain margin of freedom and creativity. The articulation of these two levels leads to a reconsideration of the question of how the designers initially conceived organizing patterns (specific schemas) and its regulation in terms of action norms for communication, on the industrial and cultural level, as well as on the more fundamental level of cognition from which they originate.The communicational dimension of the research is concerned with the insights which can be drawn from the manner in which, at the crossroads of ergonomic, psychological and cognitive approaches, a relational dimension develops in the exchanges and interactions of the various actors.
