En ces temps d’actualité terroriste, politiques, journalistes et citoyens partagent un même constat : « nous avons été attaqués dans nos libertés fondamentales. » À en croire les expressions qu’elles adoptent sur les réseaux sociaux, ces libertés fondamentales sont surtout des droits. Droit de vivre ses passions, ses désirs, ses amours, droit d’aller en terrasse, droit de boire encore des bières, de manger des frites et des moules. La circulation virale de multiples pieds-de-nez épicuriens après les attentats de ce 22 mars 2016 rappelle une fois de plus que, conformément aux clichés, le belge aime rire, bien manger et se moquer de tout qui s’attaquerait à sa belgitude. Faut-il pour autant y trouver la consolidation de ce que les terroristes risqueraient de nous dérober ? [less ▲]

Age-related macular degeneration (AMD) is a leading cause of blindness in the elderly population of industrialized countries. This blindness results from the deterioration of the macula, a small part of the retina specialized for the high-acuity vision. Exudative AMD, called “wet”, is characterized by the formation of new blood vessels growing under the retina according to a process named choroidal neovascularization (CNV). Currently, the aetiology and pathogenesis of AMD remain unclear. Nevertheless, a recent metabolomics study performed on the serum of “wet” AMD patients and on a CNV murine model, that mimics the effect of “wet” AMD, have demonstrated that lactate level is clearly involved in the severity of the pathology as well as the relationship between lactate, CNV and AMD. According to this result, we suggest a new therapeutic approach of AMD based on the normalization of blood lactate level. The modulation of the lactate plasma concentration by treatment of the animals with synthetic compounds and more specifically Pyruvate Dehydrogenase Kinase (PDK) inhibitors significantly decrease the CNV. PDK and its four isoforms (PDK1-4) regulate the activity of the pyruvate dehydrogenase complex (PDH), a mitochondrial enzyme that plays a major role in the metabolic pathway of glucose, by reversible phosphorylation. Starting from these results, development of new PDK inhibitors could open the way to innovative treatment opportunities in AMD disease. Different analogues of (R)-3,3,3-trifluoro-2-hydroxy-2-methylpropanamide (fig.1) have been already synthetized and pharmacological evaluation is currently in progress. According to the results obtained, various pharmacomodulations will be investigated [less ▲]

This paper reviews the current theoretical scholarship on maladaptation and provides some speci!c case studies—in the Maldives, Ethiopia, South Africa, and Bangladesh—to advance the !eld by offering an improved conceptual understanding and more practice-oriented insights. It notably highlights four main dimensions to assess the risk of maladaptation, that is, process, multiple drivers, temporal scales, and spatial scales. It also describes three examples of frameworks— the Pathways, the Precautionary, and the Assessment frameworks—that can help capture the risk of maladaptation on the ground. Both these conceptual and practical developments support the need for putting the risk of maladaptation at the top of the planning agenda. The paper argues that starting with the intention to avoid mistakes and not lock-in detrimental effects of adaptation-labeled initiatives is a !rst, key step to the wider process of adapting to climate variability and change. It thus advocates for the anticipation of the risk of maladaptation to become a priority for decision makers and stakeholders at large, from the international to the local levels. Such an ex ante approach, however, supposes to get a clearer understanding of what maladaptation is. Ultimately, the paper af!rms that a challenge for future research consists in developing context-speci!c guidelines that will allow funding bodies to make the best decisions to support adaptation (i.e., by better capturing the risk of maladaptation) and practitioners to design adaptation initiatives with a low risk of maladaptation.

Age-related macular degeneration (AMD) is the leading cause of vision loss in the western world among people aged 50 or older. 90% of all vision loss due to AMD result from the exudative form, which is characterized by choroidal neovascularization (CNV). Age-related changes that induce pathologic CNV are incompletely understood and critical issues remain to be addressed. Metabolomics is defined as the comprehensive study of endogenous metabolites changes in various biological systems. This newly emerging “omic” science provides a unique opportunity to correlate variation of the metabolome with pathological occurrence or progression and/or to identify metabolites that are implicated in the disease. We apply a 1H NMR metabolomics approach on sera collected from AMD patient and healthy volunteers and form a mice model of laser-induced CNV which mimics the effect of exudative AMD. After post-processing treatments, the different spectra were analyzed by statistical discriminant methodologies (PCA, ICA, PLS-DA, O-PLS-DA). These approaches allow the differentiation between control and AMD patients and between laser-induced mice and the control mice group. Moreover, the same discriminating spectral zones have been identified in human and mice model, leading to the emergence of different putative biomarkers. Among these markers, lactate emerges as a key metabolite in both settings. Mechanistically, lactate produced locally and by inflammatory cells, plays a critical role in the onset of the inflammatory and angiogenic phases. In mice model of laser-induced CNV, normalization of circulating lactate by dichloroacetate a pyruvate dehydrogenase kinase (PDK) inhibitor, decreases CNV development. Our data support the innovative concept of lactate as a parainflammation- and angio-metabolite associated to AMD and CNV progression. Moreover, control of blood lactate level via inhibition of PDK provides new options for the treatment of exudative AMD. This study demonstrates the ability of metabolomics for drug target discovery and opens new perspectives for AMD treatment and patient follow-up. [less ▲]

“Urban biorefining” is an original concept aiming at using urban wastes (household wastes, municipal wastes, industrial liquid and/or solid residues and side-products, etc.), mainly of vegetal origin, for the production of an array of biofuels and bioproducts. This “urban biorefining” concept fits particularly with the economic, geographic and politic contexts and constraints of the Walloon Region (south part of Belgium). Indeed, Walloon Region is a very small territory (area of about 6,504 sq mi) with a temperate climate. Supply feedstock, mainly arising form forestry and agriculture, are thus rather restricted, submitted to importation, and subjected to non-standardized quality. Several examples of our regional strategy, still available on an industrial scale, are herein proposed and detailed. [less ▲]

Dans la littérature concernant la délinquance, les auteurs se sont, au départ, principalement intéressés aux raisons qui poussent les individus à commettre des délits mais peu ont tenté de comprendre pourquoi et comment certains individus, qui ont commis des actes délictueux, sortent de la délinquance. En effet, la désistance, c’est-à-dire le processus de sortie de la délinquance, a longtemps été négligée par les chercheurs. À partir des années '50, un intérêt croissant pour ce domaine de recherche apparaît. La désistance devient alors un sujet d’étude indépendant et non plus un appendice de la recherche sur les carrières délinquantes (Mohammed, 2012). Malgré l’intérêt croissant pour ce champ de recherche, de nombreuses zones d’ombre persistent. Sur base d’une recherche longitudinale réalisée sur une population d’adultes en émergence délinquants (17-25ans), nous tentons d’avoir une approche holistique de la désistance. Celle-ci est définie ici comme un processus impliquant des changements individuels et sociaux, qui s’inscrit dans le temps et qui peut être marqué par des réitérations d’actes délinquants. Dans notre étude, la désistance sera étudiée à travers une approche mixte combinant un récit de vie et des questionnaires. L’approche narrative est essentielle dans notre recherche, elle permettra d’appréhender les transformations identitaires, les schémas de changement et de stabilité dans le parcours de vie et dans la trajectoire délinquante. Elle permettra également de mettre en avant les facteurs internes et externes identifiés comme des facteurs de désistance. Par ailleurs, comme Maruna (2001), nous posons l’hypothèse que les persistants et les désistants sont des individus similaires qui se trouvent à des stades différents du processus de changement. C’est pourquoi, en toile de fond, la désistance sera envisagée à travers le modèle transthéorique de Proshaska et DiClemente (1982) où différentes étapes se succèdent avant l’arrêt du comportement problématique.

In this paper we formulate answers to three important questions related to Givetian carbonate records and their use for reconstructing million-year past palaeoenvironmental changes. First, we provide detailed illustrations of the fascinating diversity that shaped a significant shallow reefal platform during the early- to late-Givetian in the Rhenohercynian Ocean; secondly we improve the sedimentological model of the extensive Givetian carbonate platform in the Dinant Basin and thirdly we evaluate the application of magnetic susceptibility (MS) as a tool for long-term trend correlations and palaeoenvironmental reconstructions. These goals are reached by making sedimentological, geophysical and geochemical study of the La Thure section. Through the early-late Givetian interval we discerned eighteen microfacies ranging from a homoclinal ramp to a discontinuously rimmed shelf and then a drowning shelf. The comparison of these sedimentological results with those published in the south of the Dinant Syncline allowed us to provide an up to date model of the vertical and lateral environmental development for one of the largest Givetian carbonate platforms in Europe. This comparison also increased the knowledge on the facies belts distribution into the Dinant Basin and allowed us to highlight the Taghanic Event. Palaeo-redox proxies reveal a substantial change in the oxygenation level, from oxygen-depleted to more oxic condition, between middle and late Givetian. We demonstrated the relationship between variation in MS values and proxies for siliciclastic input (such as Si, Al). The La Thure is considered as a key section for the understanding of internal shelf settings bordering Laurussia’s south-eastern margin. [less ▲]

Chaque année, 1% des foyers européens vit la fugue d’un de ses membres de moins de 18 ans. Au 2 janvier 2014, plus de onze mille jeunes français étaient recherchés comme fugueurs ; avec près de 50.000 fugues de mineurs français par an. En Belgique, sur les années 2013-2014, l’organisme Child Focus s’est vu confier près de 1700 dossiers de fugues de mineurs. Child Focus - Fondation pour Enfants Disparus et Sexuellement Exploités – a été créée à la suite de l’affaire Dutroux, et traite des dossiers de disparitions de mineurs (enlèvements par un tiers, enlèvements parentaux, fugues) et d’exploitation sexuelle de mineurs. Généralement contacté par la famille du jeune ou par la police, Child Focus ne peut ouvrir un dossier de fugue qu’à la suite d’un procès-verbal. Les dossiers de fugues de mineurs ouverts auprès de Child Focus constitueraient un cinquième des fugues enregistrées par la police belge. Ces dossiers, de par leur contenu, permettent d’envisager trois axes de recherche. Le premier axe porte sur le profil des jeunes signalés en fugue (âge, sexe, contexte familial, scolarité,…). Le second axe porte sur le profil du signalant (père, mère, famille élargie, police,…). Le troisième axe porte sur les indicateurs de risque et de protection que les signalants expriment auprès de Child Focus lorsqu’ils évoquent le jeune en fugue (consommation de drogue, délinquance, santé mentale,…). Ces trois axes sont étudiés à partir de deux recherches empiriques, la première portant sur les 1700 dossiers des années 2013-2014, et la seconde portant sur 200 de ces dossiers, dont nous donnerons les résultats préliminaires. Enfin, par ces recherches, nous proposons d’évaluer la portée des filtres et de la black box permettant de comprendre comment et pourquoi certains cas de fugue sont davantage susceptibles d’être confiés à Child Focus que d’autres.

In 2014, 311 million tonnes of plastics were produced worldwide while it is estimated that 10% ended up in the oceans. Plastics adsorb many pollutants, cause entanglements in many vertebrates and provoke blockage of the digestive tract of marine mammals, birds and turtles. Plastics also fragment in smaller parts, forming microplastics (<5 mm). These microplastics have the same size than planktonic organisms and can thus be ingested by filter-feeders and planktivorous organisms including fish. Although planktivorous Clupeiforme species are the most fished species in the world (17 million tonnes in 2013), the possible impact of microplastic ingestion on this group has received little attention. The aim of this study was to quantify and to characterize the ingested anthropogenic particles (AP) in herrings (Clupea harengus), sardines (Sardina pilchardus) and anchovies (Engraulis encrasicolus). Twenty individuals of each species were sampled. Herrings and sardines were caught in the Channel and in the North Sea in January 2013 and in January 2014. Anchovies were sampled in July 2013. The stomach contents were digested by sodium hypochlorite to isolate AP and then they were analysed by Raman spectroscopy and measured. AP were constituted of microplastics (MP) and cellulose fibres, sometimes associated with dyes. We found several plastic families: polyethylene (PE), polypropylene (PP), polystyrene, polyacrylonitrile, polyethylene terephthalate, polyamide and poly(butyl methacrylate). MP occurred in 35%, 50% and 40% of stomach contents of anchovies, sardines and herrings, respectively. Anchovies ingested bigger AP (2 mm) than the two other species. MP was in majority PE followed by PP. Our study shows that highly commercial species are exposed to MP. Further research is needed as MP are transport medium for organic pollutants and their fate once in the organism is unknown. [less ▲]
