Mitochondrial F1FO-ATP synthase of chlorophycean algae is a stable dimeric complex of 1,600 kDa. It lacks the classic subunits that constitute the peripheral stator-stalk and the orthodox polypeptides involved in the dimerization of the complex. Instead, it contains nine polypeptides of unknown evolutionary origin named ASA1 to ASA9. The isolated enzyme exhibited a very low ATPase activity (0.03 Units/mg), that increased upon heat treatment, due to the release of the F-1 sector. Oligomycin was found to stabilize the dimeric structure of the enzyme, providing partial resistance to heat dissociation. Incubation in the presence of low concentrations of several non-ionic detergents increased the oligomycin-sensitive ATPase activity up to 7.0-9.0 Units/mg. Incubation with 3% (w/v) taurodeoxycholate monomerized the enzyme. The monomeric form of the enzyme exhibited diminished activity in the presence of detergents and diminished oligomycin sensitivity. Cross-linking experiments carried out with the dimeric and monomeric forms of the ATP synthase suggested the participation of the ASA6 subunit in the dimerization of the enzyme. The dimeric enzyme was more resistant to heat treatment, high hydrostatic pressures, and protease digestion than the monomeric enzyme, which was readily disrupted by these treatments. We conclude that the fully-active algal mitochondrial ATP synthase is a stable catalytically active dimer; the monomeric form is less active and less stable. Monomer-monomer interactions could be mediated by the membrane-bound subunits ASA6 and ASA9, and may be further stabilized by other polypeptides such as ASA1 and ASA5. [less ▲]

Although acute hepatitis may be a side effect of many medications, most cases are reversible after treatment interruption, and fulminant hepatic failure (FHF) is rare. Venlafaxine and trazodone are 2 popular antidepressant agents. Alteration of liver enzyme levels has been reported as a side effect of these drugs at normal doses. Herein we have reported the case of a 48-year-old woman without any previous history of liver disease, who developed fulminant liver failure after 4 months of venlafaxine and trazodone therapy. She required liver transplantation, a procedure that was successful with full patient recovery. The first 5 years of follow-up were uneventful. This case documented that venlafaxine and trazodone at normal doses can produce severe liver toxicity. Liver tests should be monitored regularly in patients who receive this therapy. [less ▲]

La superficie occupée par la culture de maïs en Lorraine belge n'a cessé d'augmenter depuis le début des années 70. Comme toutes les têtes de rotation, le maïs reçoit d'importantes quantités de fumier et de lisier. Ces concentrations élevées en matières organiques associées aux engrais minéraux sont très souvent à l'origine d'un bilan azoté déséquilibré. Dans ces conditions, les reliquats en azote généralement observés dans le sol au moment de la récolte constituent un danger réel pour la qualité des nappes phréatiques. Dans cet article, nous étudions un sous-semis de ray-grass (Lolium perenne L.). Le suivi concerne d'abord la compétition entre la culture de maïs et le sous-semis. Pour les conditions pédoclimatiques de l'essai, le sous-semis n'a pas concurrencé le maïs. L'étude porte ensuite sur l'efficacité de la technique comme moyen de lutte antipollution. Les différents profils de sol prélevés ont clairement montré l'effet d'un sous-semis, effet beaucoup plus marqué sur un limon sableux que sur un sable limoneux. [less ▲]

Cette contribution à l’analyse sociologique du travail des directeurs de prison éclaire tout d’abord le fondement de ce métier : la gestion de la détention. Présentée comme "individualisée/individualisante" dans les discours politique, la gestion de la détention s'exerce toutefois dans des contextes de travail bureaucratisés (que l'on pense à la gestion du personnel, à la gestion logistique, à la gestion comptable ou à la gestion stratégique), composés de diverses scènes d’interaction (organisationnelle, politique, associative, administrative, judiciaire, interministérielle) et marqués par les « référentiels » (Muller, 2000) de judiciarisation et de managérialisation du secteur public. L’étude du travail des directeurs de prison met ensuite en lumière trois mécanismes de régulation des établissements pénitentiaires : le pouvoir des [chefs] surveillants au centre d’une « régulation autonome » (Reynaud, 1988) ; la multi-dépendance inter-organisationnelle des prisons éprouvée quotidiennement par les directeurs au centre d’une « régulation croisée » (Crozier et Thoenig, 1975) ; l’articulation ponctuelle et « prudente » (Champy, 2012), par les directeurs, des contraintes et des opportunités inhérentes aux différentes scènes sur lesquelles ils interagissent. L'analyse de certaines situations concrètes révèle enfin que le travail des directeurs n’est pas seulement technique (sur les plans juridiques et administratifs) mais aussi politique: il requiert une hiérarchisation des valeurs ou des finalités poursuivies dans leur activité.

La Lozana andaluza describes the story of a gifted prostitute which adventures occur in Rome before the Sack of 1527. However, the writer, an Andalusian priest, fills his text with biblical references. As the purpose of his Portrait gives rise to debate and is valued according to its (un)appropriateness to the Christian doctrine, we study the role of the biblical intertextuality in the determination of this purpose. Indeed, in La Lozana, the biblical hypotext presents its traditional function as an auctoritas but it also constitutes a favored tool of linguistic games, a source of comic effects, and supplies the framework of the Portrait. In this work we examine the mixed intertextuality used by an autor which anticlericalism was sometimes interpreted as an erasmist feature. Consequently, we highlight, always making links with the biblical marks of La Lozana, first some evidences that make an orthodox interpretation possible, and later some dissident tendencies that cross the story. The biblical intertextuality produces a duplicity of the discourse that prevents an univocal interpretation. In fact, this posture is understandable during a time which is disturbed by religious tensions. [less ▲]
