Le retour au premier plan de la notion de santé des écosystèmes met en évidence la préoccupation de la société à mettre en oeuvre des mesures pour la protection des milieux anthropisés. Les critères d’évaluation de la santé des peuplements piscicoles mis en oeuvre sont rarement débattus au sein de la communauté scientifique. L’exercice proposé ici devait permettre d’avoir ce débat sur la truite commune (Salmo trutta), espèce phare des cours d’eau situés en tête de bassin, qui représentent la majorité du réseau hydrographique français. La démarche visait à recueillir la conception qu’avait un nombre restreint d’experts, sur le fonctionnement de ces populations et sur les critères d’évaluation de leur fonctionnement. Les paramètres clé régulant chaque stade de développement ont été identifiés et hiérarchisés. Unconsensus s’est dégagé sur le fait que, dans l’état actuel des connaissances, le diagnostic peut être établi sur la base de l’analyse des paramètres abiotiques essentiels pour la biologie et, plus difficilement, sur l’analyse des paramètres biotiques. Pour tous les stades de développement, les paramètres identifiés sont liés à l’habitat (qualité du substrat, conditions hydrauliques, température et qualité de l’eau), l’hydrologie et la connectivité. Des connaissances demandent d’être acquises pour définir des critères biologiques. Cela implique de renforcer la surveillance biologique à long terme et les actions de recherche pour caractériser la variabilité des paramètres biologiques et identifier les échelles spatio-temporelles pertinentes et les processus fonctionnels.

Background: Heroin-assisted treatment (HAT) can improve the condition of heroin addicts who are resistant to other treatments. However, in a new HAT trial in Belgium, fewer subjects than expected were included. Aim: Our research team explored the reasons given by heroin users in explaining why they did not want to participate. Methods: In 2011, during the trial recruitment, we interviewed heroin users (n=52) who never took the opportunity to meet the research team during the recruitment process preceding the trial. Results: Of those 52 heroin users, 25 were afraid of the limited length of the HAT and 11 feared becoming more dependent as a result of HAT. Conclusion: A trial that was planned to last for a limited length of time may have demotivated heroin users who could otherwise have benefited from this new programme. [less ▲]

La mémoire du génocide des Juifs est très présente dans les sociétés occidentales à travers des vecteurs de socialisation comme l’école, les médias, la famille, et plus récemment les réseaux sociaux et Internet. Quelles peuvent être les conséquences de la transmission de cette mémoire sur le développement des attitudes et des comportements politiques des jeunes ? C’est la question centrale de l’ouvrage qui présente les connaissances, les émotions et les valeurs mobilisées par les jeunes dans le cadre de groupes de discussion, et qui surtout les met en perspective avec leurs représentations et leurs perceptions des autorités politiques. Au final, plusieurs questions difficiles pour le futur émergent. En effet, à bien des égards, l’impact de la transmission de la mémoire du génocide des Juifs sur la socialisation politique des jeunes pose la question de l’éventualité de sa répétition, de son caractère exceptionnel, de sa compréhension, ou encore de l’effacement de sa mémoire dans la dynamique des générations et du temps qui passe.

In a context of increasing demand for meat and fish, the animal production sector is seen as a driver of growth for agriculture in Hai Duong Province, Vietnam. However, the growth prospects of this sector seem undermined by a limited credit supply. This study aims to explore access to credit by animal producing households, factors affecting their credit accessibility and the influence of credit and non-credit factors on animal production. The study results show that all households surveyed, both the animal-based group and the non animal-based group, need credit for both production activities and consumption. The formal sector, which for the most part provides credit for production activities, did not meet the credit needs of the animal producers. Thus, only 52% of surveyed households applied to commercial banks for credit, the remaining households felt that they had no chance of receiving loans. Looking at the household characteristics as the center for analysis, it was found that physical collateral, the area of the fish pond and social relationships positively affected the probability of credit access by animal producing households. In addition, the area of the fish pond, number of laborers, share of income from animal production and social relationships positively affected the borrowing amount that was approved by commercial banks. Among animal producing households, the poor households likely had a lower probability of credit access and lower borrowing amounts than the non-poor households. The credit needs of farmers were often more rationed by commercial banks. Furthermore, some weaknesses of the rural lending apparatus in Hai Duong Province impeded access to credit by households. The credit constrained households accounted overall for 71% of the households surveyed. On the other hand, both the animal-based group and the animal-based group also suffered from some non-credit constraints relating to production and marketing. Within each group, the non-credit constraints caused a similar negative influence on animal production income, relatively speaking. Credit accessibility was different among households. As a result, for a given production unit, credit constrained households generated less income than non-credit constrained households. Improving the credit supply and some non-credit factors is expected to increase income from animal production. The study mainly suggests that the local authorities should support small-scale animal producers to establish animal producer groups to overcome constraints to credit access, production and marketing. Besides strengthening the credit supply to individual borrowers, the formal sector should grant feed purchase credit vouchers to animal producing groups. [less ▲]

In Vietnam, the vermicelli of Canna edulis Ker Gawl. (C. indica L.) is an artisanal and traditional product, regularly consumed in the festive occasions. From Canna edulis Ker Gawl cultivation to trading of vermicelli of Canna edulis at the local level, the vermicelli commodity chain belongs to peasant economy with many actors involved. This research aims at a better understanding of how the actors of vermicelli commodity chain adapt to current socio-economic and environmental conditions of the villages which belong to two communes (Tu Dan and Yen Phu) located in Hung Yen Province. The surveys among 90 farmers and discussions with a group of producers who cultivate the canna and practice flour processing, and a group of vermicelli processors have been carried out from 2010 to 2012. According to our research results, vermicelli commodity chain has created a considerable additional quantity of jobs for local people within the villages of vermicelli processing and the neighboring ones. Thanks to these activities, the rural households income and production investment have been increased. Net income estimated per hectare of canna is about 22.2 million VND (about 822 €), and nearly 4.5 million VND (167 €) per ton of flour produced, and up to 1.7 million VND per ton of vermicelli product (about 63 €). In addition, these activities allow to diversify the sources of family incomes in the countryside. These activities also contribute to stabilize and increase the living standard of farmers (in 2010, the net family income (NFI) due to canna production accounted for 8% to 34 % of farming income; the NFI of vermicelli processing represented between 35% and 86 % of total processing family income). The value-added generated from this vermicelli commodity chain is important, up to 186 million VND (about 7,900 €) per hectare of canna, in which 38 % for flour processing; 20% for vermicelli processing and 20 % for canna cultivators. Thus, the vermicelli commodity chain contributes to meet a specific demand for traditional food in Vietnam. This chain contributes to the rural economy of traditional villages through improving the sources of familial income. However, it is necessary to increase the product quality and to improve the vertical and horizontal linkages between the actors in order to guarantee the sustainable development of this vermicelli chain.

For several years, mesenchymal stem cells (MSC) have been evaluated in vivo and in vitro for their immunomodulatory, anti-inflammatory, anti- ischemia-reperfusion injury and “tissue repair” properties. These characteristics could make them interesting in various clinical applications, and particularly in organ transplantation. Taking advantage of our centre expertise and experience concerning MSC use in graft-versus-host disease after bone marrow transplantation and using already functioning GMP-compliant laboratory able to produce clinical-grade MSC, we initiated in 2011 a first trial exploring safety and tolerability of third party MSC infusions after kidney or liver transplantation in a prospective phase I-II study. In this study, after successful transplantation, 10 liver and 10 kidney transplant recipients under standard immunosuppressive treatment (tacrolimus, mycophenolate, steroids) receive an intravenous infusion of 1.5 - 3x106/kg of third-party MSC, on post-operative day 3+/-2. These patients are prospectively compared to the same number of liver and kidney transplant recipients who meet inclusion criteria but do not receive MSC infusion. Safety is assessed by recording side effects, including opportunistic infections and cancers. Immunosuppressive potential is evaluated by rejection episode rates, graft/patient survivals, immunohistology of 3-month (kidney) and 6-month (liver) graft biopsies, and in vitro evaluation of recipient immunity profile. In a second step, reduction (kidney) and progressive weaning (liver) of immunosuppression is attempted in recipients who received MSC. Inclusion of liver patients is now complete, and to date 3 kidney patients received MSC. Primary results will be presented, and complete 6-month liver results are expected for the end of 2014. The next step will be to assert the immunosuppressive potential of MSC after organ transplantation, and the opportunity to develop larger randomised, controlled, phase III trials. [less ▲]
