Mener un projet international
Internet, construction européenne, mondialisation… : notre horizon ne s'arrête plus à nos frontières. Du jumelage à la coopération décentralisée, les municipalités demandent à leurs services de participer à des projets à dimension internationale. Processus de Bologne, formation tout au long de la vie, internationalisation des études, les universités font elles aussi appel à leurs services pour les accompagner dans ces évolutions. C'est dans ce contexte que s'inscrit ce volume, avec l'ambition de fournir à tous les professionnels des bibliothèques des clés de compréhension de ces nouveaux enjeux ainsi que des exemples concrets d'actions de coopération soutenus par des apports méthodologiques. Comment travailler et partager avec des partenaires étrangers ? Quelles sont les étapes fondamentales d'une coopération : de la convention à l'évaluation ? Qui sont nos relais en France et à l'étranger pour de tels projets ? C'est à travers ces questions que s'organise l'ouvrage, en proposant des éléments de préparation pratiques pour mener ces actions internationales et les pérenniser. Coordonné par Raphaëlle Bats, conservateur chargée des relations internationales à l'enssib, et écrit par différents acteurs du terrain, l'ouvrage traite également de la mobilité des professionnels et des voyages d'étude, du bibliothécaire-formateur ou expert, d'action culturelle et de politique documentaire (du don des documents à l'avenir du patrimoine en Europe en passant par la lecture pour les enfants)

Combined effect of gamma irradiation, ascorbic acid and edible coating to improve microbial and biochemical characteristics of ground beef
This study was conducted to evaluate the combined effect of gamma irradiation and the incorporation of natural antimicrobial compounds in cross-linked films on the microbiological and biochemical characteristics of ground beef. Medium-fat (23% fat) ground beef patties were divided into three separate treatment groups: (i) control samples without additives, (ii) ground beef samples containing 0.5% (wt/wt) ascorbic acid, and (iii) ground beef samples containing 0.5% ascorbic acid and coated with a protein-based cross-linked film containing immobilized spice powders. Meat samples were irradiated at doses of 0, 1, 2, and 3 kGy and stored at 4 +/- 2 degrees C. Microbial growth (based on total aerobic plate counts [APCs] and total coliforms) was evaluated, as were the content of thiobarbituric acid-reactive substances (TBARS) and that of free sulfydryl groups. At the end of the storage period, Enterobacteriaceae, presumptive Staphylococcus aureus, presumptive Pseudomonas spp., Brochothrix thermosphacta, and lactic acid bacteria were enumerated. Regardless of the treatment group, irradiation significantly (P < or = 0.05) reduced the APCs. Irradiation doses of 1, 2, and 3 kGy produced immediate APC reductions of 2, 3, and 4 log units, respectively. An APC level of 6 log CFU/g was reached after 4, 7, and 10 days for samples irradiated at 1, 2, and 3 kGy, respectively. Lactic acid bacteria and B. thermosphacta were more resistant to irradiation than were Enterobacteriaceae and Pseudomonas. The TBARS and free sulfydryl contents were stabilized during postirradiation storage for samples containing ascorbic acid and coated with the protein-based cross-linked film containing immobilized spice powders

Valproate, divalproex, valpromide: Are the differences in indications justified?
International audienceIn many countries, valproate is indicated for epilepsy only, whereas its derivative divalproex (DVP) and valpromide (VPM) are indicated for bipolar disorders only. DVP is composed of sodium valproate and valproic acid (VA) in a 1:1 molar ratio and VPM is a prodrug completely hydrolyzed in the gastric tract to VA. Whatever the drug, the absorbed and active substance is the valproate ion. In this article, we reviewed the potential reasons that might justify these different indications. We performed a literature review of comparative studies of efficacy, pharmacokinetic parameters, side effects and costs for VPA, DVP, and VPM. We found only studies comparing VA with DVP. None of the eight efficacy studies found differences in epilepsy or mood disorders. The ten studies of side effects reported a difference in terms of gastrointestinal effects, but inconsistently. The United States (US) summary of product characteristics and kinetic comparison studies reported bioequivalence between DVP and VA, but a longer Tmax for DVP, likely due to its gastro-resistant galenic form. VPM summary of product characteristics and pharmacokinetic studies revealed a lower bioavailability (80% vs. 100% for VA) and a delayed Tmax. There is an additional cost for using DVP or VPM as compared to VA (respectively +177% and +77% in France). The differences in indications between valproate derivatives do not seem justified. Interchangeability between VA and DVP in bipolar disorders seems possible, at identical dosage. VPM would require a closer dosing schedule and a 20% reduction in dosage when switching to valproate

Donor KIR3DL1/3DS1 Gene and Recipient Bw4 KIR Ligand as Prognostic Markers for Outcome in Unrelated Hematopoietic Stem Cell Transplantation
International audienceGiven their antileukemic activity, natural killer (NK) cells can alter the outcome of hematopoietic stem cell transplantation (HSCT). The physiologic functions of NK cells are regulated by the interaction of killer immunoglobulin-like receptors (KIR) with specific HLA class I ligands. In the literature, different models based on HLA class I and/or KIR donor (D)/recipient (R) gene disparities are considered as predictors of NK cell alloreactivity. In this retrospective and multicentric French study, we analyzed the clinical impact of the different NK-alloreactivity models in 264 patients who underwent T repleted unrelated HSCT. First, we did not observe that the ''KIR ligand-ligand'' model had a significant clinical impact on unrelated HSCT outcome, whereas the ''missing KIR ligand'' model had a significant but limited effect on unrelated HSCT, because only the absence of C1 ligand in patients with myelogenous diseases was associated with a decreased overall survival (OS) (hazard ratio 5 2.17, P 5.005). The ''KIR receptor-receptor'' and the ''KIR receptorligand'' models seemed the most capable of predicting NK alloreactivity because they had a significant impact on acute graft-versus-host disease (aGVHD) occurrence, OS, and relapse incidence in D/R unrelated pairs. In particular, KIR3DL1 gene mismatches in the GVH direction (D 1 R 2) and the D KIR3DL1 1 /3DS1 1 and R Bw4 2 combination were respectively correlated with the lowest OS in HLA identical pairs (HR 5 1.99, P 5.02) and the highest incidence of relapse in HLA nonidentical D/R unrelated pairs (HR 5 4.72, P 5.03). Overall, our results suggest a detrimental effect of KIR3DL1 1 /3DS1 1 donor NK cells transplanted into HLA-Bw4 2 patients in the absence of an educational process via KIR3DL1/HLA-Bw4 interactions
