We recently mapped a quantitative trait locus (QTL) with a major effect on milk composition-particularly fat content-to the centromeric end of bovine chromosome 14. We subsequently exploited linkage disequilibrium to refine the map position of this QTL to a 3-cM chromosome interval bounded by microsatellite markers BULGE13 and BULGE09. We herein report the positional candidate cloning of this QTL, involving (I) the construction of a BAC contig spanning the corresponding marker interval, (2) the demonstration that a very strong candidate gene, acylCoA:diacylglycerol acyltransferase (DGATf), maps to that contig, and (3) the identification of a nonconservative K232A substitution in the DGAT1 gene with a major effect on milk fat content and other milk characteristics.

Double-muscling in cattle is a generalised hypertrophy of skeletal muscle resulting from a hyperplasia of the myofibers. Using a positional cloning strategy, we have identified the gene underlying double-muscling, namely myostatin, and causal loss-of-function mutations therein. Myostatin is a novel member of the TGF-beta superfamily of growth and differentiation factors. Using conditional gene targeting in a murine model, we have demonstrated that post-natal muscle specific inactivation of the myostatin gene causes full-blown double muscling. This demonstrates the potential value of myostatin antagonist whether to promote muscle regeneration in patients suffering from muscle wasting disease, or to enhance meat production in livestock species. Finally, by targeting a myostatin transinhibitor on the Y chromosome, we have demonstrated in the mouse the feasibility of a more efficient cattle production system combining superior beef production abilities for bulls and dairy abilities for cows.

Parallèlement à la croissance exponentielle de ses ventes et de sa notoriété, le mouvement du commerce équitable (CE) connaît une diversification croissante de son paysage organisationnel (Nicholls & Opal, 2005; Wilkinson, 2007). Alors qu’à ses débuts, le mouvement était porté par des organisations militantes relativement homogènes, celles-ci se sont progressivement diversifiées, tandis que de nouveaux acteurs sont apparus avec une dynamique commerciale plus marquée (Gendron, 2004; Moore, 2004; Renard, 2003). Si toutes les organisations de commerce équitable (OCE) ont en commun de chercher à soutenir des organisations de producteurs au Sud à travers une activité commerciale « équitable » dans le cadre d'un développement durable Nord-Sud, les stratégies adoptées peuvent fortement différer (Wilkinson, 2007). Ainsi, en caricaturant quelque peu, certaines OCE misent principalement sur le partenariat commercial, encadré par un processus de labellisation, et prônent un développement essentiellement quantitatif de la filière, notamment à travers la distribution des produits en grandes surfaces. D'autres, par contre, insistent plus sur la qualité des partenariats avec les producteurs marginalisés et misent sur les activités de sensibilisation des citoyens et de lobbying auprès des pouvoirs publics dans le but de modifier en profondeur les règles du commerce international. Quelle que soit leur stratégie, les OCE sont inévitablement confrontées aux tensions traversant l’ensemble du mouvement équitable. Ces tensions semblent pouvoir se résumer, globalement et malgré certaines nuances dans les appellations, à deux grands pôles : le pôle économique, de « marché » d’une part, et le pôle socio-politique, de « solidarité » d’autre part. Ce qui différencie les OCE, c’est donc la manière de gérer cette tension et de se positionner par rapport à ces différentes logiques. L’objectif de cette contribution est précisément d’éclairer ces différents positionnements organisationnels sur le « continuum » entre l’économique et le socio-politique. Nous commençons par présenter ce continuum du CE sur lequel les acteurs se positionnent. Nous proposons ensuite différents indicateurs organisationnels susceptibles d'appréhender ces positionnements. A partir de la théorie des organisations appliquée à différentes formes organisationnelles, nous nous penchons sur les objectifs organisationnels, les ressources, le statut juridique et la composition des éventuelles instances de gouvernance (principalement l'assemblée générale et le conseil d'administration). Nous rappelons dans quelle mesure, selon la littérature, ces indicateurs peuvent être révélateurs du positionnement stratégique de l'organisation. Ensuite, nous proposons quatre profils organisationnels possibles pour gérer les tensions entre les différents pôles du CE. Chacun de ces profils est caractérisé par rapport aux indicateurs organisationnels proposés : objectifs déclarés, types de ressources mobilisées (ventes, dons, subventions, bénévolat), statut juridique (association, coopérative, entreprise individuelle, société anonyme,...) et composition des instances de gouvernance (types de parties prenantes impliquées). Chaque profil est ensuite illustré par des exemples d'organisations provenant de trois études de terrain réalisées auprès d’OCE en Belgique, en France (dans la région Rhône-Alpes) et au Royaume-Uni. Enfin, après une synthèse de ces quatre profils, nous nous penchons sur leurs implications sur l’avenir du mouvement équitable. Nous cherchons à percevoir l'évolution des stratégies de positionnement des OCE de manière à distinguer les perspectives futures de la filière. La question posée est de savoir si les différents profils de positionnement peuvent continuer à coexister de manière complémentaire ou si, au contraire, ils mènent à l'apparition de différentes formes de CE n'ayant plus en commun que leur appellation.

The results are presented of photographic observations of asteroid positions made in August 1976 at La Silla, Chile. The quality of the sky characteristics made it possible to record objects with the magnitude 17. Measurements of all plates were conducted with the aid of the Ascorecord measuring machine of the Royal Belgian Observatory. The reduction method employed is based on the use of five reference stars. The equatorial planet coordinates can be easily obtained from the employed parameters with the aid of the formulas considered by Smart (1944). In the evaluation procedures use was made of the SAO catalog which had been recorded on magnetic tape by the Strasbourg Observatory. Three new asteroids were discovered. The obtained data are presented in two tables. [less ▲]

Dissociation processes leading to positive and negative ions in ketene are discussed on the basis of appearance potential measurements. All important positive and negative ions are examined. For the negative ions, only resonance dissociative attachment processes are considered. Excited electronic states of negative ions, in particular for O-, may explain the structure observed in the dissociative attachment efficiency curves. [less ▲]

We report systematic investigation of duplex DNA complexes with minor groove binders (Hoechsts 33258 and 33342, netropsin and DAPI) and intercalators (daunomycin, doxorubicin, actinomycin D, ethidium, cryptolepine, neocryptolepine, m-Amsacrine, proflavine, ellipticine and mitoxantrone) by ESI-MS and ESI-MS/MS in the negative ion mode and in the positive ion mode. The apparent solution phase equilibrium binding constants can be determined by measuring relative intensities in the ESI-MS spectrum. While negative ion mode gives reliable results, positive ion mode gives a systematic underestimation of the binding constants and even a complete suppression of the complexes for intercalators lacking functional groups capable of interacting in the grooves. In the second part of the paper we systematically compare MS/MS fragmentation channels and breakdown curves in the positive and the negative modes, and discuss the possible uses and caveats of MS/MS in drug-DNA complexes. In the negative mode, the drugs can be separated in three groups: (1) those that leave the complex with no net charge; (2) those that leave the complex with a negative charge; and (3) those that remain attached on the strands upon dissociation of the duplex due to their positive charge. In the positive ion mode, all complexes fragment via the loss of protonated drug. Information on the stabilization of the complex by drug-DNA noncovalent interactions can be obtained straightforwardly only in the case of neutral drug loss. In all other cases, proton affinity (in the positive ion mode), gas-phase basicity (in the negative ion mode) and coulombic repulsion are the major factors influencing the fragmentation channel and the dissociation kinetics.
