Clinical use of gentamicin over prolonged periods is limited because of dose- and time-dependent nephrotoxicity. Primarily, lysosomal phospholipidosis, intracellular oxidative stress and heightened inflammation have been implicated. Hydrogen sulphide is an endogenously produced signal transduction molecule with strong anti-inflammatory, anti-apoptotic and cytoprotective properties. In several models of inflammatory disease however, tissue damage has been associated with increased activity of cystathionine gamma-lyase, biosynthesis of hydrogen sulphide and activation of leukocytes. The aim of this study was to determine effects of inhibiting hydrogen sulphide biosynthesis by DL-propargyl glycine (an irreversible inhibitor of cystathionine gamma-lyase) on inflammation, necrosis and renal function, following treatment with gentamicin in rats. Adult female Sprague–Dawley rats were divided into six groups and treated with; physiological saline, sodium hydrosulphide, DL-propargyl glycine, gentamicin, a combination of gentamicin and sodium hydrosulphide, or gentamicin and DL-propargyl glycine respectively. Gentamicin-induced histopathological changes including inflammatory cell infiltration and tubular necrosis were attenuated by co-administering gentamicin with DL-propargyl glycine (Pb0.05 compared to saline controls and Pb0.05 compared to gentamicin only). Similarly, DL-propargyl glycine caused a significant reduction (Pb0.05) in lipid peroxidation, production of superoxide and the activation of tumour necrosis factor-alpha in gentamicin-treated animals. These data show that protective effects of DL-propargyl glycine might be related at least in part, to the reduced inflammatory responses observed in animals treated with both gentamicin and DL-propargyl glycine. Thus, enzyme systems involved in hydrogen sulphide biosynthesis may offer a viable therapeutic target in alleviating the nephrotoxic effects of gentamicin. [less ▲]

Hatcheries, input dealers, farmers, collectors and processors are the primary actors of shrimp value chain in the Mekong River Delta (MRD) Vietnam, a sector that has many problems of disease, shrimp seed, environmental pollution, and management skills. Holding the strongest power in the shrimp value chain, the processors determine shrimp prices and set up requirements of shrimp quality and size in the market though quality control has not been completely implemented due to the limitations of financial capital, knowledge, awareness, as well as the quality of raw material supplied by collectors and farmers. Farmers stayed in the weakest position in the chain due to their small individual scale, and low skills. The results of the study show that most of the shrimp farmers stay out of vertical integration under farming contracts while the rest joined in the game without success. Contract farming seems not for small scale farmers who account for a large part in the MRD, and not interesting for producers who get success with their cultivation. Farmers prefer a non-contract option due to non-transparency of interest share as well as cost account. Food safety standards, decision No. 80/2002/QĐ-TTg, culture, trust, government structure, credit support and corruption are the main factors affecting farmers’ integration chances. Floor price mechanism, risk sharing, small scale of the model of vertical integration and excess suppliers in the market, administrative misconception and inefficient public management are the main reasons of failures of contract farming of two case studies in the MRD. Planning and projection of shrimp production zones are therefore the priority matters to address. Furthermore, re-organizing shrimp farmers into legal teams or groups or cooperatives is also necessary to increase the size of the existing shrimp cultivation units in Vietnam in order to improve the sector.

According to the Water Framework Directive (WFD 2000/60), our rivers and water bodies are required to achieve the “good ecological status” by 2015. This requirement is related to the physico-chemical, biological water quality as well as the hydromorphological quality. In this context, a LIFE Environment project, co-founded by the European Union and the Service Publique de Wallonie, was launched in 2009 for a period of five years. It aims to realize the experimental and demonstrative river restoration works on three “at risk” water bodies, based on two axes: longitudinal continuity and transversal continuity. The first two selected water bodies (Bocq, eastern tributary of the Meuse) are suitable for the restoration works which concern the longitudinal continuity due to the presence of dams and other obstacles between 1 and 3 m high. These works consist in dam management (weir removal or fish ladders) taking into account hydromorphological (bedload transport) and biological (invertebrate or fish species free movement) impacts. The third water body (Eau Blanche, western tributary of the Meuse) presents straightened rivers with artificial banks which consequently lead to poor connections between the stream and its floodplain. This water body is therefore appropriated for the works based on the transversal continuity recovery. These works consist in enhancing straightened river channel and restoring meanders or banks. Until now, these works have been realized on more than 5 km. These works are being monitored on the basis of geomorphological and ecological analysis. The geomorphological monitoring is based on surveys conducted before and after the works. It concerns the bedload transport, the clogging of the gravel layer and the morphological changes of the river following the works. The ecological monitoring is based on two indicators: macroinvertebrates and fishes. Standardized and repeatable methods were developed to compare the situation before and after the works, especially through the analysis of microhabitats. In addition, we use another two complementary indexes of physical quality for this monitoring. Developed by the consulting office Teleos, these indexes have a fish orientation and have been implemented in many of our stations. [less ▲]

Today, consumer behavior has become a key concept in scientific publications and in international public health strategies. Both 'behavior' and the 'consumer' are in the title of the 3rd annual conference of the Belgian Nutrition Society. This paper proposes a reflection on these concepts, and invites for further discussion. Firstly, the 'consumer' and his attributes will be briefly explored through an analysis of the Health Claims Regulation EC No 1924/2006. This document, intended to protect consumers from misleading information, uses a model of the consumer rooted in rational choice theory. Secondly, as medical sociologist David Armstrong (2009) has shown, the term 'behavior' has been brought in relation to health outcomes only relatively recently in medicine and public health. As such, it has come to be defined as a modifiable risk factor. I argue that European public health strategies have integrated this definition of behavior and the related idea of 'lifestyle' into rational choice theory. As such, 'behavior' and 'lifestyle' frame problems of health and disease in a specific way. The third section of this paper will confront this model of problem-framing with different understandings of 'behavior' coming from historical and contemporary sociological research. [less ▲]

This thesis investigates fractured zones leading to preferential groundwater flow paths. In this context, we used the electrical resistivity tomography (ERT) and the self-potential (SP) methods to identify, characterize, monitor, and finally model preferential flow in hydraulically-active fractured zones at a scale representative of real world applications. From an experimental point of view, we first identified the magnitude of self-potential signature, a -15 mV anomaly that could be associated with preferential groundwater flow in a shallow quartzite aquitard whereas the streaming potential theory was originally developed for porous media. This signature was confirmed experimentally in limestone aquifers at greater depths. The joint use of surface ERT and SP allowed the identification of water-bearing fractured areas which were electrically more conductive, presenting contrasts from 1 to 10 and which were hydraulically-active presenting negative SP anomalies ranging from -10 to -30 mV. We were also able to correlate hydraulic heads and SP gradients during a low and a high groundwater level period leading to interesting perspectives in understanding the dynamics of complex groundwater flow systems. Finally, a preferential flow and rapid transport path, over 10 m/h, was highlighted in a 20 m deep fractured and karstified limestone valley by monitoring a salt tracer test with only surface ERT. This methodology was being mostly used for relatively shallow and homogeneous aquifers up to now. Such information is crucial to set up new monitoring wells or to define the sampling rates of classic tracer test. From a methodological point of view, we quantitatively assessed the efficiency of blocky and minimum-gradient-support regularizations in electrical imaging to recover sharp interfaces on numerical benchmarks and with field data. The usefulness of resolution indicators such as the cumulative sensitivity matrix and the resolution matrix were also assessed in this context. We demonstrated that noise characterization is crucial in time-lapse inversion and may supplant the choice of the time-lapse inversion scheme, calling for a systematic analysis of reciprocal measurements (or a subset of them). We also showed that, when using data differences in an inversion scheme, the data error, as estimated by time-lapse reciprocal measurements, depends on the mean measured resistance. These error characterization studies should always be performed if one wants to avoid wrong interpretations about the hydrodynamics. We further showed that focused inversion techniques (blocky inversion, minimum-gradient-support) may offer great perspectives when recovering model changes in time-lapse inversion. Finally, ERT and SP were jointly used to conceptualize a physically-based and spatially distributed hydrogeological model, in particular to characterize the preferential flow paths. Predicted hydraulic heads and SP-derived hydraulic heads using the water table model showed a clear correlation, leading to perspectives in terms of hydrogeological model calibration. Further experiments are however needed to fully estimate the streaming potential apparent coupling coefficient, but the use of the full SP signals for hydrogeological model calibration is a clear perspective to this work.

On peut distinguer dans la correspondance de Guichardin trois moments historiques au cours desquels la liberté est mise en danger par les armes. Premièrement, l’ambassade espagnole de 1512, lorsque le jeune Guichardin est envoyé en mission auprès du roi d’Espagne pour sonder ses intentions. Ensuite, l’année 1525, moment de constitution de la ligue de Cognac, durant laquelle Guichardin consacre une partie de son temps à la rédaction de discours contradictoires sur le meilleur comportement politico-militaire à adopter pour « libérer l’Italie ». Enfin, l’année 1527 qui voit le terrible sac de Rome. Si la notion de liberté est généralement associée au bien-être, à la paix et à la santé, de Florence dans la première période, de la péninsule dans le deuxième moment, de Florence et de la Péninsule dans le troisième et justifie – paradoxalement – le passage aux armes pour la défendre, la conserver ou, pire, la restituer, selon les moments, le mot « liberté » ne recouvre toutefois pas le même sens. Lorsqu’il s’agit de protéger Florence, Guichardin entend défendre l’autogestion de la ville pourtant sous gouvernement médicéen ; la « liberté commune » ou « liberté d’Italie » renvoient à la seule absence d’étrangers dans la péninsule, alors qu’en 1527, lors du retour à un gouvernement populaire à Florence, la « libertà della città » n’est autre que l’appellation pour désigner ce même gouvernement populaire républicain. Tandis que, sur le terrain, les soldats s’affrontent pour « libérer » tel morceau de l’Italie – au sens renaissant d’ensemble de cités-état vivant en équilibre – voire la péninsule entière de tout occupant étranger, dans ses lettres Guichardin mène le même combat, tentant par la force de la plume de faire fléchir les uns et de convaincre les autres, n’hésitant pas à exploiter les multiples sens recouverts par le mot « liberté ».
