Transition vers des systèmes agricole et agroalimentaire durables : quelle place et qualification pour les légumineuses à graines ?
2017
Cet article propose une analyse historique du processus de verrouillage du système agroalimentaire en défaveur des légumineuses à graines, à l’aune des théories évolutionnistes. Plusieurs mécanismes d’autorenforcement permettent de comprendre pourquoi ces espèces sont de moins en moins cultivées en France face à un système agro-industriel qui s’est spécialisé en faveur des céréales, favorisant à l’amont l’usage d’engrais azotés de synthèse et limitant à l’aval les investissements pour les légumineuses en alimentation humaine. Cet article s’interroge alors sur les perspectives de déverrouillage.
Whey proteins are more efficient than casein in the recovery of muscle functional properties following a casting induced muscle atrophy.
2013
International audience; The purpose of this study was to investigate the effect of whey supplementation, as compared to the standard casein diet, on the recovery of muscle functional properties after a casting-induced immobilization period. After an initial (I0) evaluation of the contractile properties of the plantarflexors (isometric torque-frequency relationship, concentric power-velocity relationship and a fatigability test), the ankle of 20 male adult rats was immobilized by casting for 8 days. During this period, rats were fed a standard diet with 13% of casein (CAS). After cast removal, rats received either the same diet or a diet with 13% of whey proteins (WHEY). A control group (n =…
Resveratrol-induced xenophagy promotes intracellular bacteria clearance in intestinal epithelial cells and macrophages
2019
International audience; Autophagy is a lysosomal degradation process that contributes to host immunity by eliminating invasive pathogens and the modulating inflammatory response. Several infectious and immune disorders are associated with autophagy defects, suggesting that stimulation of autophagy in these diseases should be bene ficial. Here, we show that resveratrol is able to boost xenophagy, a selective form of autophagy that target invasive bacteria. We demonstrated that resveratrol promotes in vitro autophagy-dependent clearance of intracellular bacteria in intestinal epithelial cells and macrophages. These results were validated in vivo using infection in a transgenic GFP-LC3 zebra f…
Dimagrire in regime mediatico
2012
publication en italien : BOUTAUD Jean-Jacques, « Dimagrire in regime mediatico », Dietetica e semiotica. Regimi di Senso, a cura di Dario Mangano e Gianfranco Marrone, Mimesis Edizioni, Milano, 2013, p. 19-38; Il titolo può leggersi in molti modi. Per esempio: dietetica e semiotica sono due regimi di senso, uno alimentare e l'altro comunicativo, con pari dignità, dunque da paragonare fra loro. Oppure: grazie alla semiotica la dietetica appare, non più come un regime alimentare, ma come un regime di senso. O anche: regimi alimentari e regimi di senso sono due facce della medesima medaglia, e si rafforzano a vicenda. Se stare a dieta, come insegnavano gli antichi, non è soltanto star attenti …
