    Intervention aux 5èmes Rencontres FORMIST (Lyon, 9 juin 2005). La collaboration entre enseignants et bibliothécaires aborde une nouvelle étape avec la mise en place de la réforme LMD. Ce travail collectif est fortement lié, dans le même temps, à l\u27évolution des outils documentaires. La présentation de la coopération entre les enseignants de l\u27UFR Sciences de la vie de l\u27université Louis-Pasteur (ULP – Strasbourg-I) et le SCD montre comment ces deux paramètres peuvent se compléter pour proposer une forme de collaboration inédite

    Dans le cadre de ces 2es rencontres FORMIST (Formation à l\u27information scientifique et technique), deux tables rondes ont été organisées, le matin sur le thème de la stratégie et des partenariats entre universitaires et professionnels de l\u27information, et l\u27après-midi sur les méthodes pédagogiques et le contenu des formations. Les présentations des diverses expériences ont été suivies de débats dont les auteurs, conservateurs stagiaires à l\u27enssib, retranscrivent ici les grandes lignes et les principales observation

    Pharmaceutical proteins in plants. A strategic genetic engineering approach for the production of tuberculosis antigens.

    International audienceTuberculosis (TB) is a re-emerging disease that is considered a major human health priority as well as an important disease of livestock. TB is also a zoonosis, and Mycobacterium tuberculosis and M. bovis, the human and bovine causative agents, respectively, are very closely related. Protection against TB is essentially achieved through vaccination with the Bacille Calmetle-Guerin (BCG) strain of M. bovis. Protection is, however, incomplete, and novel improved vaccines are currently under investigation. Production of protective antigens in transgenic plants, or "pharming," is a promising emerging approach, and a zoonosis-like TB is a good model for investigating the potential of this approach. Pharma-Planta, a European Commission-funded project and consortium, was set up to address this topic, within which a component is aimed at assessing the production efficacy and stability of the TB antigens in different compartments of the plant cell. This article is meant to introduce this promising approach for veterinary medicine by describing the ongoing project and its specific genetic engineering strategy

    Protein Crystallography under Xenon and Nitrous Oxide Pressure: Comparison with In Vivo Pharmacology Studies and Implications for the Mechanism of Inhaled Anesthetic Action

    In contrast with most inhalational anesthetics, the anesthetic gases xenon (Xe) and nitrous oxide (N(2)O) act by blocking the N-methyl-d-aspartate (NMDA) receptor. Using x-ray crystallography, we examined the binding characteristics of these two gases on two soluble proteins as structural models: urate oxidase, which is a prototype of a variety of intracellular globular proteins, and annexin V, which has structural and functional characteristics that allow it to be considered as a prototype for the NMDA receptor. The structure of these proteins complexed with Xe and N(2)O were determined. One N(2)O molecule or one Xe atom binds to the same main site in both proteins. A second subsite is observed for N(2)O in each case. The gas-binding sites are always hydrophobic flexible cavities buried within the monomer. Comparison of the effects of Xe and N(2)O on urate oxidase and annexin V reveals an interesting relationship with the in vivo pharmacological effects of these gases, the ratio of the gas-binding sites' volume expansion and the ratio of the narcotic potency being similar. Given these data, we propose that alterations of cytosolic globular protein functions by general anesthetics would be responsible for the early stages of anesthesia such as amnesia and hypnosis and that additional alterations of ion-channel membrane receptor functions are required for deeper effects that progress to “surgical” anesthesia
