Le projet DÉRom est certainement l'entreprise la plus innovante pour l'étude historique du lexique roman depuis le Romanisches Etymologisches Wörterbuch de Wilhelm Meyer-Lübke. Lors de cette communication, nous avons tenté de mettre en lumière quelques-uns des apports théoriques et méthodologiques du projet, lancé en janvier 2008 par Éva Buchi (aujourd'hui directrice du laboratoire ATILF, Nancy) et Wolfgang Schweickard (professeur de philologie romane à l'Université de la Sarre, Sarrebruck). L'axiome principal, qui semble tout à fait évident mais dont les implications ont rarement été mesurées en linguistique romane, est qu'une langue écrite ne peut être l'ancêtre d'une langue orale. Dès lors, la reconstruction de la proto-langue ne peut s'appuyer que sur la comparaison des cognats romans, sans tenir compte, dans un premier temps, du témoignage des textes latins. [less ▲]

The Advanced Telescope for High-energy Astrophysics (Athena+) is being proposed to ESA as the L2 mission (for a launch in 2028) and is specifically designed to answer two of the most pressing questions for astrophysics in the forthcoming decade: How did ordinary matter assemble into the large scale structures we see today? and how do black holes grow and shape the Universe? For addressing these two issues, Athena+ will provide transformational capabilities in terms of angular resolution, effective area, spectral resolution, grasp, that will make it the most powerful X-ray observatory ever flown. Such an observatory, when opened to the astronomical community, will be used for virtually all classes of astrophysical objects, from high-z gamma-ray bursts to the closest planets in our solar neighborhood. In this paper, we briefly review the core science objectives of Athena+, present the science requirements and the foreseen implementation of the mission, and illustrate its transformational capabilities compared to existing facilities.

Biosurfactants which are surface active molecules produced by micro-organisms present a wide structural diversity (glycolipids, lipoaminoacids, lipopeptides, polymers,...) and numerous advantages compared to their chemically synthesized counterparts. Among glycolipids, rhamnolipids which are secondary metabolites produced mainly by strains of Pseudomonas aeruginosa, have drawn particular attention as they have several interesting biological properties such as antimicrobial, antiphytoviral, zoosporicidal and plant defense elicitor activities [1-3]. It is generally recognized that these activities must be linked to the interaction of these molecules with constituents of biological membranes [4] but the detailed mechanism is far from being fully understood. In our laboratory, new rhamnolipids with various chain lengths and with or without a terminal carboxylic acid function were obtained via the development of a synthesis procedure consisting of two biocatalyzed steps involving naringinase and lipase [5]. The objective of this work was to investigate their interaction with model membranes in relation with their structure in order to give insight about the mechanism of their biological action. A range of complementary experimental and modelling methods was used to analyze their interaction with membrane models. Results reveal differential interaction with lipids according to the structure of the rhamnolipid. The nature of the lipid is also a key parameter for the ınteractions. [less ▲]

The mixed symmetric positive and negative parity baryons are described in a similar way in the $1/N_c$ expansion method of QCD by using a procedure where the permutation symmetry is incorporated exactly. This allows to express the mass formula in terms of a small number of linearly independent operators. We show that the leading term follows a different Regge trajectory from that found for symmetric states, when plotted as a function of the band number $N$. [less ▲]

Glycolipid surfactants constitute a class of natural compound having interest in biological field such as antifungal, antiviral and plant-elicitor and for pharmaceutical formulation as well as for food and cosmetic field. Their action may be modulated through their interactions with plasma membranes of target cells and more particularly by their interactions with membrane lipid molecules. Among glycolipid surfactants, bolaforms constitute an important class; they are composed of two hydrophilic heads connected by a hydrophobic carbon segment.Their interest lies mainly in the development of the efficient and low cost lipid-based drug delivery systems. In this context, our work was focused on two sugar-based bolaforms. They are composed by two identical hydrophilic head constituted by xylose ( BolaX) or rhamnose ( BolaR), connected by an ether link to a hydrocarbon segment with an insaturation. The interactions of  BolaX and BolaR with model phopsholipid and phospholipid/sterol model membranes (Langmuir monolayers at the air-water interface and multilamellar vesicles) were investigated with biophysical and in silico approaches. Our results indicate that both bolaforms interact with model membranes at the level of hydrocarbon chain and, at the phosphate and the carbonyl group of phospholipids. The presence of sterol in the system has an influence on insertion of bolaforms and change slightly the nature of the interactions. The insertion of BolaR within a phospholipid bilayer was deeper than that of  BolaX and its interactions with phospholipids were energetically more favorable, suggesting an important role of the nature of sugar residue.

In agriculture, the concept of sustainable development emergence and its omnipresence in political discourses suggests that farming systems move toward systems considered as more environment-friendly and human health-friendly. In Benin, cotton is one of the most sectors concerned by this transformation. Indeed, in spite of the importance of cotton in the economy of Benin, its sustainable production is nowadays threatened by conventional production approach. Various alternatives of production are developed and considered as more environment-friendly than the conventional production approach. This article analyses the sustainability of the organic and cotton made in Africa (CmiA) farming alternatives from the sustainable agricultural intensification theoretical perspective. Structured and non-structured interviews with individuals and focus groups were used to collect data from 90 organic cotton farmers of the municipality of Kandi, and 100 CmiA farmers of the municipality of Pehunco, one of the largest areas of cotton production in the North of Benin. Data were analyzed with methods of normative and relativist comparison, descriptive statistics and analysis of variance. Kolmogorov-Smirnov (K-S) test was used to verify the normality conditions and in some cases, logarithmic transformation was done to test the variance homogeneity. The comparison of means was done with the test of Least Significant Difference. It appears from the results that in the current condition of implementation, the alternatives system to conventional cotton production approach are not intensively sustainable. Soils fertility and pests’ management face enormous constraints and do not allow improvement of yields, economic performances, and environment protection. So, the sustainability of the alternative systems of cotton production is not guaranteed and can hardly become a reality if additional relevant conditions are not created. [less ▲]

Face à la libéralisation du marché, à l’externalisation des échanges et aux progrès technologiques, les entreprises doivent, à présent, jongler entre des dispositifs et des mesures destinés à assouplir le marché du travail, tout en procurant une certaine sécurité et stabilité à leur main-d’œuvre. C’est dans ce cadre que cette communication vise à comprendre et à saisir la manière dont les très petites entreprises (TPE) et les petites et moyennes entreprises (PME) belges francophones tentent de concilier flexibilité et sécurité dans ce contexte de mondialisation et de concurrence exacerbée (Auer, 2008). En d’autres termes, nous verrons d’une part, quels dispositifs de flexibilité et de sécurité ces deux types d’entreprise mobilisent dans leur gestion de l’emploi et d’autre part, dans quelle mesure ces dispositifs sont propres à leurs structures configurationnelles et pratiques de gestion des ressources humaines (GRH), à l’aune de la théorie de la contingence structurelle (Mintzberg, 1982 ; Pichault et Nizet, 2000). À l’aide de 67 entretiens semi-directifs réalisés au sein de 54 TPE/PME belges, nous déterminerons tout d’abord, les pratiques de GRH véhiculées sur base d’indicateurs de flexibilité et de sécurité préalablement définis et ensuite, le type de configuration prédominant en proposant un modèle explicatif des facteurs et enjeux influençant ces pratiques.

S’agissant d’une référence qui demeure incontournable en psychologie clinique et en psychopathologie, nous proposons de partir du cadre psychanalytique. Nous ferons le constat de difficultés tant théoriques que techniques concernant les notions d’espace, de temps et, plus fondamentalement, concernant le corps qui est cantonné à sa disposition hystérique. Par ailleurs, nous verrons que la phénoménologie permet de penser ce corps en tant que fondement de notre identité et de notre relation à l’autre. Il s’agit d’une donnée implicite qui n’est pas interrogée, une « sentinelle silencieuse » pour reprendre les propos de Merleau-Ponty. À partir de là, nous pourrons exposer en quoi la problématique schizophrénique se situe au niveau d’une rupture anthropologique quant à la manière de vivre son corps. Nous développerons également la différence qu’il y a entre le corps-pour-soi et le corps-pour-autrui et celle entre le corps paranoïde et le corps paranoïaque. Enfin, en guise de mise en perspective, nous développerons les concepts deleuzien de territorialisation et de ritournelle et montrerons en quoi le clinicien, s’il a à prendre en compte le corps de son patient dans sa réflexion, doit avant tout accepter de mobiliser son propre corps, de toucher son patient, de l’observer et de se laisser toucher par lui.

Objet. Etude comparative des performances analytiques de tests immunochromatographiques pour la détection du streptocoque A dans les frottis de gorge : Quickvue (Quidel), bioNexia (bioMérieux), Clearview (Inverness medical), Dipromed et All-Diag. Méthodes. Les prélèvements utilisés ont été réalisés avec les E-Swab de chez Copan. Un total de 106 échantillons a été testé, dont 58 positifs et 48 négatifs. Environ la moitié des échantillons a été testée avec le format cassette et l’autre moitié avec le format dipstick pour les kits bioNexia et Clearview. Par ailleurs, les kits Dipromed et All-Diag (tous deux au format dipstick) ont été groupés dans cette étude car ils sont identiques (information confirmée par les fournisseurs). Les résultats des tests rapides ont été comparés à ceux de la culture prolongée. Les échantillons ont été ensemencés sur milieu CNA, avec disque de bacitracine pour l’identification présomptive du streptocoque A. Un groupage à l’aide de tests d’agglutination (Oxoid) et/ou une identification de la souche sur l’automate Vitek 2 (bioMérieux) ont été réalisés pour identification formelle. Sur base des résultats de l’étude, nous avons calculé la sensibilité et la spécificité de chaque kit. Ces valeurs ont ensuite été appliquées à la prévalence de cultures positives pour le streptocoque A observée au CHR Citadelle, en 2012. Nous avons ainsi pu calculer les valeurs prédictives positives (VPP) et négatives (VPN) sur notre population réelle. Résultats. La sensibilité est excellente pour tous les kits, comprise entre 93,1% (Clearview) et 96,6% (Quickvue). La spécificité est de 95,8% pour le Quickvue, tandis qu’elle est de 97,9% pour tous les autres kits. Sur la population du CHR Citadelle (2012), les VPP sont de 77,6% pour le Quickvue, et se situent aux alentours de 87% pour les autres kits. Les VPN sont excellentes et vont de 99 à 99,5%. Conclusion. Les valeurs de sensibilité et spécificité obtenues dans cette étude sont conformes à celles attendues pour ce genre de kit selon la littérature, c’est-à-dire respectivement supérieures à 90% et 95%. Les VPP observées avec le test Quickvue sont péjorées par l’existence d’un faux positif de plus. Les autres kits présentent une quasi-équivalence analytique dans notre série. [less ▲]

La sylviculture du douglas (Pseudotsuga menziesii) en Wallonie est récente et présente des modalités opératoires très contrastées. Aussi, pour guider l’action des sylviculteurs, une étude technologique visant à évaluer l’impact du dynamisme de la sylviculture sur les propriétés du bois de douglas a été initiée. Il est accepté aujourd’hui que l’angle des microfibrilles de cellulose (AMF) de la paroi des trachéides, ainsi que la longueur des trachéides, peuvent expliquer largement le comportement du bois sans défaut. Dans un premier temps, l’étude a porté sur les variations de l’AMF et de la longueur des trachéides au sein des arbres en fonction de paramètres tels que leur vitesse de croissance, l’âge du cerne, la position radiale ou la hauteur dans l’arbre. Ultérieurement, ces résultats seront utilisés pour tenter d’expliquer les propriétés mécaniques du bois sur la base de ses caractéristiques anatomiques. Il sera alors possible de relier les caractéristiques de croissance avec les propriétés du bois produit afin de proposer les pratiques sylvicoles les plus pertinentes. [less ▲]

Vingt pourcents des forêts du Bassin du Congo sont actuellement principalement affectées à la production de produits ligneux et non-ligneux [FAO-OIBT, 2011]. L'exploitation est un agent de perturbation de ces forêts [WILKIE ET AL., 2000]. Au vu de l’importance économique des industries d’extraction pour les pays de cette région, l’étendue des forêts exploitées pour leur bois ne devrait pas diminuer dans les années à venir, au contraire. La survie de nombreuses espèces animales de forêt dense humide dépend donc de leur capacité à survivre en milieu exploité [JOHNS, 1985]. A ce jour, les concessions forestières jouent potentiellement un rôle crucial pour la protection des différentes espèces de grands singes. En effet, plus de 50% de l'aire de distribution des grands singes d’Afrique de l'Ouest est localisée dans les concessions forestières [MORGAN & SANZ, 2007]. Or, la faune sauvage joue un rôle essentiel pour la durabilité de l'exploitation forestière car elle assure la dissémination des graines [WRIGHT, 2003], dont celles des espèces commerciales. En particulier, le gorille des plaines de l'Ouest (Gorilla gorilla gorilla Savage & Wyman, 1847), espèce en danger critique d'extinction (IUCN), semble jouer un rôle fondamental dans la dispersion des diaspores des espèces ligneuses [ROGERS ET AL., 1998 ; VOYSEY ET AL., 1999]. Cette étude vise à déterminer les interactions entre les gorilles des plaines de l'Ouest et l'exploitation forestière, afin d'évaluer dans quelle mesure ces deux acteurs peuvent être bénéfiques l'un envers l'autre. Plus particulièrement, la densité en gorilles a été estimée dans une zone exploitée 25 ans plus tôt. Le comportement nidificateur des gorilles dans cette zone a été décrit. D'autre part, le rôle potentiel joué par les gorilles dans la dynamique de régénération des forêts exploitées est abordé au travers de l'étude de la dispersion des graines (identification des graines dispersées, contrôle du pouvoir germinatif et détermination de l'impact du passage dans le tractus digestif sur la germination). La densité en gorilles observée au sein du site d'étude est relativement élevée (1,5 gorille/km²). Les gorilles établissent leurs sites de nidification préférentiellement au sein de forêts de terre ferme à canopée ouverte. Ils utilisent fréquemment les anciennes routes d'exploitation, densément couverte de végétation herbacée, pour l'alimentation et la nidification. Au bout de 10 mois de suivi, 45 espèces végétales ont été identifiées comme étant dispersées par les gorilles. Le potentiel germinatif a été évalué pour 36 taxons. Les taux de germination observés dépendent de l'espèce considérée, et varient de 0 à 100%. L'impact du tractus digestif sur la germination a actuellement été testé pour deux espèces, Santiria trimera (Burseraceae) et Chrysophyllum lacourtianum (Sapotaceae). Pour ces deux espèces, les graines passées dans le tractus digestif des gorilles présentent des taux de germination significativement plus élevé que les graines extraites de fruits frais (entourées de pulpe ou non). Les résultats préliminaires de cette étude suggèrent que les forêts exploitées peuvent supporter des densités en gorilles comparables à celles des aires protégées. En outre, via son rôle en tant que disperseur, le gorille pourrait avoir un rôle crucial dans la régénération des forêts post-exploitation. L'exploitation forestière et la conservation des gorilles des plaines de l'Ouest paraissent donc compatibles. [less ▲]

The awareness of environment and the development of environmental product declarations (EPDs) are increasing through years. EPD becomes a need for producers in both B to B and B to C relations. EPD elaboration process is not without difficulties. Such a declaration requires a considerable amount of time and information, a full comprehension of the applied methodology but it also causes confidentiality problems. All these difficulties can lead to the use of simpler tools, as Carbon Footprint, which only focuses on a single impact and misses a part of the message. This case study is based on the production of phosphoric acid in Belgium using PCR for inorganic chemicals. It takes into account the use of raw materials as phosphate rocks or chemicals, their transportation to site and the manufacturing of defluorinated and purified phosphoric acid. This process also requires steam, electricity, demineralised water and sulphuric acid. These inputs are produced on site and their modelling is taken into account in this study. The first step of this process is the production of weak phosphoric acid with transformation of phosphate rocks into 30% phosphoric acid using sulphuric acid attack. The particularity of this process is the production, in this company, of a recoverable coproduct, called gypsum. The amount of this product is about 1.6 t per t of weak acid. A stoichiometric relation connects both products and is used as allocation factor, as recommended by the PCR. Through next concentration steps, fluosilicic acid is produced, also linked to the production of phosphoric acid by a stoichiometric relation. For facilities production plant, repartition of impact between coproducts is not so easy. As mentioned before, the production of steam, electricity, demineralised water and sulphuric acid are performed on site. Sulphuric acid is produced by the combustion of liquid sulphur provided by oil refineries. Two different units produce both sulphuric acid and steam through the combustion of liquid sulphur but only one of them transforms a part of steam into electricity. Repartition of impact between sulphuric acid and steam can be achieved using a physical relation based on thermodynamic values which can be transformed into mass relation. For repartition between electricity, steam and sulphuric acid, the main difficulty is that electricity does not have a weight and a transformation into steam shall be achieved to use the same relationship that previously. This way of allocating is not very obvious for producers, even if it is the one recommended by the PCR. As electricity and steam are coproduced, an energetic allocation is also relevant and gives completely opposite results for repartition of impact of each product. In that case, sulphuric acid impact achieves a non-negligible part of the impact which modifies greatly results of phosphoric acid production. This is a problem when you know that environmental product declarations are used to compare products on environmental criteria, using mainly values of climate change or energy impacts. Producers are then reticent to publish such a value which can lead to a loss of customer confidence, even more when they occupy a leading position on the market and taking into account that a comparison with other producers is quite impossible. More specific guidelines should be set to indicate the best way to perform an environmental product declaration in specific fields using a specific way of allocation. [less ▲]

Nous montrons que cette innovation consiste en un déplacement de l’objet même de la prise en charge, passant désormais de la relation d’emploi à la transition professionnelle, probablement annonciatrice de mutations plus profondes sur le marché du travail.

L’évolution de la perception sociétale du bien-être animal et de l'élevage engage la production à chercher des alternatives aux cages conventionnelles. Dans cette expérimentation en engraissement en conditions de production, durant un an, les performances (techniques et statut sanitaire) ont été suivies dans un logement en parcs hors sol (bâtiment 1), sur plancher en caillebotis en plastique normalement conçu pour porcelets, enrichis avec une plate-forme surélevée, matériau à ronger et cachette. Sans effectuer une comparaison scientifique de deux systèmes (parc hors sol et cage), les auteurs situent les performances enregistrées en parcs durant 7 bandes (960 lapins par bande) vis-à-vis de celles obtenues simultanément dans le même élevage, dans un logement en cages conventionnelles et enrichies (bâtiment 2), en tout plein tout vide (7 bandes et 4200 lapins par bande). Les parcs hors sol, a priori profitables au bien-être animal, non bivalents (donc changement au sevrage) ont été défavorables à la santé des lapins et à la viabilité de la production. La coccidiose intestinale a contribué à une hausse sévère de la mortalité (13,8% contre 4,8% en cages) ; de fortes baisses de performances techniques et économiques ont été constatées et la situation a contraint à un traitement anticoccidien.

The abundance and interest of the epigraphic evidence from the is- land of Cos after the synoecism of 366 BC makes it a very valuable case-study for understanding how the religious life of a polis was organized in the Hellenistic period. The topic of civic priesthoods is particularly well documented by various types of inscriptions, such as priesthood regulations, sacrificial calendars and contracts of sales. Based on a close study of this evidence, this paper will exa- mine the roles played by priests in the cults of the gods of the civic pantheon, as well as the relationship between these officials and the polis which appointed them. It will address as its main question how the priest’s position as mediator between the polis community and the divine sphere was manifested. [less ▲]

The craze for biofuels has increased in recent years mainly to reduce greenhouse gas emissions and fossil fuel consumptions. The European Renewable Energy Directive (RED), published in 2009, defined guidelines to assess carbon footprint of a biofuel depending on biomass source. It also provided generic values of GHG emissions relative to each step of the life cycle taking into account all steps from the cultivation to the end-of-life. These values are used to evaluate the sustainability of European biofuels depending on the used crops and the used transformation technology. This study, based on local crops cultivated in Belgium (sugar beet and wheat), compares specific Belgian values with European generic ones. Belgium yields for both crops are among the best of the continent. Specific Belgian values for fertilizers and pesticides are used. The transformation of wheat into bioethanol is modelled using industrial data. As recommended by the RED, no land use change is taken into account for Belgium. Greenhouse gas emissions induce by the life cycle of Belgium sugar beet bioethanol are similar to the ones mentioned in the European directive but impact repartition is different. In our case, the transformation step achieves a higher part of the impact. That can be explained by the higher cultivation yield. Belgian wheat bioethanol obtains better results than those mentioned by the European directive with a 9% higher reduction. Cultivation step is the major step for this impact. Importance of fertilizers consumptions and associated emissions are highlighted. The comparison of both bioethanols impacts for climate change category, using an energy basis, shows that wheat allows a higher reduction of GHG emissions than sugar beet. If the comparison is performed on a cultivated area basis, results are reversed and sugar beet achieves a twofold reduction compared with wheat. Sensitivity analyses are performed on the importance of N fertilizers and associated emissions and on energy consumptions relative to the transformation step. These analyses reveal non-negligible impact variations. A range of GHG reduction that can be reached using Belgian sugar beet and wheat bioethanol are then calculated. In any case, sugar beet does not achieve the amount of reduction given by the RED, while the opposite effect is shown for wheat with a reduction at least as high as the RED default value. These results indicate the importance of make use of specific values to assess the sustainability of bioethanol for a specific country using a specific crop and a specific technology. Further measurements and research about emission factors due to fertilizers application could improve the accuracy of our results. [less ▲]

In [8,7], the properties of generalized uniform Hölder spaces have been investigated. The idea underlying the definition is to replace the exponent α of the usual spaces Λ^α(R^d) (see e.g. [6]) with a sequence σ satisfying some conditions. The so-obtained spaces Λ^σ(R^d) generalize the spaces Λ^α(R^d); the spaces Λ^σ(R^d) are actually the spaces B^{1/σ_{∞,∞}(R^d), but they present specific properties (induced by L^∞-norms) when compared to the more general spaces B^{1/σ}_{p,q}(R^d) studied in [2,4,1,5,9,10] for example. Indeed it is shown in [8,7] that most of the usual properties holding for the spaces Λ^α(R^d) can be transposed to the spaces Λ^σ(R^d). Here, we introduce the pointwise version of these spaces: the spaces Λ^{σ,M}(x_0), with x_0∈R^d. Let us recall that a function f∈L^∞_loc(R^d) belongs to the usual pointwise Hölder space Λ^α(x_0) (α>0) if and only if there exist C,J>0 and a polynomial P of degree at most α such that sup_{|h|≤2^{−j}} |f(x_0+h)−P(h)|≤C2^{−jα}. As in [8,7], the idea is again to replace the sequence (2^{−jα})_j appearing in this inequality with a positive sequence (σ_j)j such that σ_{j+1}/σ_j is bounded (for any j); the number M stands for the maximal degree of the polynomial (this degree can not be induced by a sequence σ). By doing so, one tries to get a better characterization of the regularity of the studied function f. Generalizations of the pointwise Hölder spaces have already been proposed (see e.g. [3]), but, to our knowledge, the definition we give here is the most general version and leads to the sharpest results.

Computing the spectrum of singularities of a real-life signal by using the definition is impossible. One rather uses an indirect way to compute it: the multifractal formalism. The first multifractal formalism was introduced by Frisch and Parisi in the context of fully developped turbulence (1985). Its main default is that it always leads to a concave spectrum. For this reason, Stéphane Jaffard has introduced the Snu spaces (2004). They lead to a new multifractal formalism which can detect non concave spectra. In practice, one has to avoid the concept of limit and to deal with finite size effects. I present a method to determine the spectrum based on the Snu spaces and I illustrate it numerically on theoretical functions. [less ▲]

The Multicoloured Asian Ladybird, Harmonia axyridis Pallas (Coleoptera: Coccinellidae) is known to thrive principally in shrubby and arboreal habitats. Its occurrence in agroecosystems remains poorly documented. This study focuses on the occurrence of this exotic species and its seasonal abundance in various field crops. The abundance of adults and larvae of H. axyridis was evaluated over a four-year period, from 2009 to 2012, in four important agronomical crops (wheat, corn, broad bean and potato) in Belgium. A total of 28 aphid predator species were observed including 14 coccinellid species, 13 hoverfly species and one lacewing species. H. axyridis is present and reproduces in all of the four crops studied, with the largest numbers recorded in corn and broad bean crops. In corn, H. axyridis numbers were found to increase over the four inventoried year, reaching 86% of the aphid predators in 2012, while it represented only 15% in 2009. H. axyridis was not always recorded where aphids were abundant, e.g. aphids were abundant on wheat where no H. axyridis were recorded. H. axyridis starts reproducing after the peak in aphid population, suggesting that H. axyridis is able to complete its development by feeding on alternative prey such as larvae and pupae of the same and other species of ladybird and other aphidophagous species. H. axyridis is often considered to be bivoltine but it only completes one generation per year in field crops. The second generation generally develops late in the season in other habitats. Harmonia axyridis is an invasive and an intraguild predator present in high quantities in some specific crops. In these crops, H. axyridis could negatively impact on population of native species due to IGP observed in several other studies. [less ▲]

Since the early years 1990 when the first cord blood (CB) banks were created, the worldwide inventory has grown considerably to a current 590 thousand units that complement the 22 M donors to provide hematopoietic progenitor cells (HPC) to patients in need of an allogeneic transplantation. The existing inventory shows a high degree of heterogeneity with a significant number of units below the current transplantation standards for adult patients. In the mean time, the use of CB as a HPC source has remained steady over the last years, leading to a relative decrease in the release activity in each individual bank. New challenges and innovations have emerged, such as: • More stringent regulations in the USA and in the EU • Upgrades in professional standards • Competing transplantation approaches such as easier access to adult unrelated donors (UD), use of haplo identical donors, single or multiple CB transplantation • CB collection safety becoming a concern since issues have been raised about the outcome of newborns linked to their iron status • The definition of clear criteria for transplant selection (HLA typing level, cell contents) • Potential role of CB banks in non hematological CB use (use of CB byproducts, generation of iPS from selected universal donors, immunotherapy, HIV therapy) • Financial restrictions The elements mentioned above have lead banking strategies, including recruitment, donor selection, CB collection, processing, storage and release to evolve considerably and to incorporate • Active volunteer accreditation processes for international recognition • Donor recruitment: more detailed and selective donor evaluation • Systematic nucleic acid (NAT) testing for infectious disease markers (IDM) • Extensive use of molecular HLA typing and widening range of loci to be taken into account • Evolving definition of acceptance criteria for incoming CB units, (i.e. stricter TNC requirements) • Well standardized processing and storage methods • Evaluation and adaptation of supply vs. needs in strategic approaches • Need to increase and optimize CB visibility through up to date electronic solutions • Methods to have a permanent and up to date overview of post transplantation outcomes, including elements relevant to the banking and clinical side Professional organizations (NetCord, WMDA, FACT, WBMT) are in the process of tightening their links in order to increase interactions and respond in time to upcoming challenges and evolutions of the field.

LGBT (Lesbian, Gay, Bisexual and Transgender) couples and parented families were often neglected by family and couple systems theory and practice. This inattention is mostly rooted in homophobia,heterocentrism and heteronormativity that influenced dominant definitions of "healthy" and "functional" relationships. Whether we are researchers or clinicians, it is interesting to consider the impact of these stressors. Especially in the clinical contexts, it seems important to assess the degree of minority stress, relational ambiguity and social support in order to address the LGBT unique challenges. In this presentation, we will discuss these challenges and through clinical vignettes we will underline the importance of an eco-systemic approach and the creation of new possibilities to be and to do a couple and a family.

Abstract Background: The prevalence of chronic pathologies such as cardio-vascular diseases is increasing, in part due to dietary habits. Some dietary patterns may influence health more than individual foods, nutrients or food groups. The objective of this research was to identify dietary patterns associated with common cardiovascular risk factors (CVRF) in a sample of adult individuals living in the Greater Region. Methods: Data were taken from the cross-sectional NESCAV (Nutrition, Environment and Cardiovascular Health) study, aiming to describe the cardiovascular health of the Greater Region’s population (1). Dietary intake was assessed using a 132-item food frequency questionnaire (FFQ), from which 44 food groups were formed. Food group consumptions were adjusted for energy intake using the residuals method of Willet and Stampfer (2). Participants under a special diet to manage their CVRF were excluded. Likewise, those who had a history of cardiovascular disease or with confirmed diabetes, hypertension, and/or dyslipidemia were also discarded as they may have changed their diet. Thus, a total of 1691 individuals were included in the study (865 from Luxembourg, 527 from Wallonia and 299 from Lorraine). We applied the reduced rank regression method to identify specific dietary patterns strongly associated with common CVRF (3). The CVRF-specific dietary patterns were constructed by choosing intake data as predictors and CVRF as outcomes. Nine CVRF (BMI, waist to hip ratio, total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, blood glucose, diastolic and systolic blood pressure) were used in the statistical analysis. Associations between dietary patterns and CVRF were adjusted according to gender, age, smoking status and level of physical activity. Results: Two main dietary patterns were identified. A pattern characterized by high intakes of alcohol, potatoes and high-fat food such as pastries, fried foods, offal, processed and smoked meat, margarine, but low intakes of cereals, soups, soft drink and olive oil, was significantly associated with an increase of all CVRF. On the other hand, a healthy pattern characterized by high consumption of brown bread, nuts, soups, vegetables, smoked and canned fish, olive oil and oil rich in omega 6 and 3, high-fat dairy products, butter and margarine, but a low consumption of fried foods, rice/pasta, meat, ready meal, soft drink and beer, was associated with a decrease of all CVRF except LDL. Conclusions: Our results suggest that dietary patterns of the Greater Region population are related to CVRF. Diet rich in alcohol and high-fat food is associated with a higher cardiovascular risk whereas a healthy diet is associated with a lower cardiovascular risk. These results emphasize the need for cross-border preventive nutritional strategies. [less ▲]

L'environnement et les changements climatiques, ainsi que la mondialisation des échanges commerciaux internationaux peuvent affecter la distribution des pathogènes et/ou des arthropodes vecteurs. Actuellement, l’espèce Aedes albopictus Skuse est considérée comme le moustique le plus invasif dans le monde entier et l’un des plus importants vecteurs d’arbovirus (notamment chikungunya et dengue). En Belgique, Ae. albopictus a été introduit pour la première fois en 2000 à Vrasene (Province de Flandre-Orientale), dans une entreprise de recyclage des pneus usagés en provenance des États-Unis et du Japon. Plusieurs autres inspections ont été effectuées (2001-2012) après ce premier rapport, mais aucun autre spécimen n’a été trouvé. L’espèce était considérée comme éliminée naturellement et aucune nouvelle introduction n’avait été signalée. Dans le cadre d'une étude de surveillance de moustiques réalisée dans plusieurs endroits à travers la Belgique en 2013, un adulte mâle d’Ae. albopictus a été capturé à l'aide d’un piège à CO2 à Vrasene dans la même entreprise de recyclage de pneus (51°12'49" N, 4°11'37" E; juillet 2013). L’espèce a été confirmée par identification morphologique et moléculaire. Cette redécouverte d’Ae. albopictus ainsi que son absence durant les treize dernières années, démontrent sa réintroduction en Belgique via le commerce de pneus usagés. Une étude sur la survie et la dispersion de ce moustique en Belgique, ainsi que de son écologie dans les pays voisins pourrait fournir des indications importantes pour élucider davantage son caractère invasif et identifier les zones à haut risque. Contexte Aedes albopictus (Skuse, 1894) (Diptera: Culicidae), communément appelé « le moustique tigre », est une espèce invasive originaire d’Asie du Sud-Est. Une nouvelle réintroduction de ce vecteur d’arbovirus a été enregistré en été 2013 en Belgique. Cette présentation abordera successivement : (a) L’invasion d’Ae. albopictus et importance médicale, (b) (Ré)-Introduction d’Ae. albopictus en Belgique, (c) Risque lié à l’introduction et à l’adaptation d’Ae. albopictus en Belgique, (d) Gestion de risque et contrôle. a. Invasion d’Ae. albopictus et importance médicale Depuis la fin des années 70s, Ae. albopictus connait une propagation explosive dans le monde entier où il est considéré actuellement comme le moustique le plus invasif dans le monde (1). La mondialisation des échanges commerciaux, notamment les pneus usagés (2) et le Lucky Bambou (3), est un facteur clé de cette invasion. En Europe, il a été signalé dans 20 pays et est aujourd'hui bien installé dans la région méditerranéenne (1). Ae. albopictus fait partie des plus importants vecteurs d’arbovirus, en particulier pour les virus de la dengue et du chikungunya (1), et des filarioses animales notamment Dirofilaria spp. (4). Le risque d'apparition et la propagation de ces arbovirus aux régions non épidémiques ont surtout augmenté dans les régions où Ae. albopictus est établi. Cette hypothèse est démontrée à plusieurs reprises, notamment les récentes transmissions autochtones du chikungunya et de la dengue en Italie, en Croatie et en France (1). b. (Ré)-Introduction d’Ae. albopictus en Belgique En Belgique, Ae. albopictus a été introduit pour la première fois en 2000 à Vrasene (Province de Flandre-Orientale), dans une entreprise de recyclage des pneus usagés en provenance des États-Unis et du Japon (5). Plusieurs autres inspections ont été effectuées (2001-2012) après ce premier rapport, mais aucun autre spécimen n’a été trouvé (6, Schaffner données non publiées). L’espèce était considérée comme éliminée naturellement et aucune nouvelle introduction n’avait été signalée (6). Cependant, une étude sur la surveillance de moustiques réalisée dans plusieurs endroits à travers la Belgique en 2013 a de nouveau signalé la capture d’Ae. albopictus à Vrasene, dans la même entreprise de recyclage de pneus. Cette redécouverte d’Ae. albopictus, ainsi que l'absence de toute constatation au cours des années précédentes (2001-2012), démontre sa réintroduction en Belgique via le commerce des pneus usagés (7). c. Risque lié à l’introduction et à l’adaptation d’Ae. albopictus en Belgique Aedes albopictus est un vecteur efficace confirmé des virus de la dengue et du chikungunya (1), ainsi que des filarioses animales notamment Dirofilaria spp. (4) ; la Belgique enregistre de plus régulièrement des cas de chikungunya importés (8). Ainsi, s'il s'établit dans le pays, Ae. albopictus peut devenir une menace importante et réelle pour la santé humaine et animale tant par son rôle de vecteur d'agents pathogènes que par sa nuisance. d. Gestion de risque et contrôle Une étude sur la survie et la dispersion d’Ae. albopictus en Belgique, ainsi que sur sa bio-écologie dans les pays voisins pourrait fournir des indications importantes pour élucider davantage son caractère invasif, et identifier les zones à haut risque. Une réponse proactive rapide est essentielle pour la lutte anti-vectorielle afin d’éviter son installation en Belgique. Cela inclut la mise en œuvre rapide de mesures de contrôle, avant que l’élimination ne devienne impossible (9). Les programmes de surveillance et de contrôle doivent cibler davantage toutes les zones possibles d’introduction de ce vecteur, en particulier les entreprises du commerce international des pneumatiques et des plantes ornementales telle que le Lucky Bambou. Ces programmes doivent également être appliqués durant toute la saison d’activité d’Ae. albopictus, sous une logique de lutte anti-vectorielle intégrée (10). A cet effet, l’appel aux moyens de lutte mécanique et les traitements larvicides sont fortement recommandés. Le recours aux traitements adulticides cependant, sera justifié uniquement en cas d’abondance de l’espèce due à de nouvelles réintroductions. Conclusion Les réintroductions d’Ae. albopictus en Belgique via l’importation de pneus usagés, l’environnement favorable à son installation et la confirmation régulière de cas importés du chikungunyia rendent la Belgique vulnérable aux risques d’une transmission autochtone de cette maladie infectieuse. Vu que plusieurs pays d'Europe de l'Ouest connaissent actuellement des introductions répétées d'Ae. albopictus sur leurs territoires, la mobilisation et la coordination des surveillances entomologiques entre ces pays - y compris la Belgique - sont devenues plus que nécessaires afin de traquer toutes les voies potentielles de réintroductions.

This speech aims to address two theoretical challenges to which every scholar interested in the performance of social enterprises is confronted: the problem of defining what performance exactly is and the integration of the complexity inherent to social enterprises in the definition of performance (Speckbacher, 2003; Meadows and Pike, 2010; Samples and Austin, 2009; Polonsky and Grau, 2008). Our point is that the performance literature does not currently provide satisfying answers to these challenges. The first challenge identified is the confusion in the literature surrounding the definition of organizational performance (Quinn & Rohrbaugh, 1983). Performance scholars contributed to this confusion by each using an own definition of performance unrelated to any wider theoretical framework or by even bypassing the definition issue (Campbell, 1977). As they rarely share common definitions of performance, the accumulation of a body of common knowledge remains illusionary. In any case, performance scholars stick to isolated definitions and hardly recognize that multiple contingent definitions of performance can coexist in a consistent framework. The second challenge is closely related to the first one as it also concerns the definition of performance. For social enterprises, the performance definition step is an essential issue because, unlike for-profit corporations often do, relying only on straightforward performance indicators such as financial ratios would not be sufficient. Therefore they have to work on with a more complex definition of performance, which forces them to deepen the definition issue even more carefully. These challenges are addressed in the two sections of this paper. The first challenge is tackled in the first section of the paper, in which we compare the relative advantages of two bodies of literature likely to serve as basis for the definition of performance for social enterprises. This first section concludes with the relevance of rejuvenating an old body of literature, namely “organizational effectiveness” , which is likely to provide answers to the confusion plaguing the definition issue in the performance literature. Based on that theoretical finding, we develop a second section in which we review the OE literature to deal with the second challenge. This body of literature can potentially offer strong theoretical bases to integrate the complexity of social enterprises, except that the interrelationships between the existing OE approaches have never been explicitly stressed up to now. Therefore we address this research gap by setting up a framework articulating the existing OE approaches, which can open the way to integrate the complexity of social enterprises. [less ▲]

The peptide studied here was designed to form beta amphiphilic films with the aim to stabilize purified membrane proteins. This interaction has notably been followed by FRET. Hydrophobic and hydrophilic residues are alternate and positively and negatively charged residues place respectively at the start end the end of the peptide. The peptide has been studied by atomistic and coarse grained molecular dynamics in water, chloroform and mixed solutions. The peptide was observed to spontaniously form beta films at the chloroform water interface. Moreover, when we simulate the interaction of this peptide with a membrane protein and with a membrane protein in a micelle of dodecylphosphocholine. The peptide was observed to form beta films at the membrane protein surface and even remove surfactants from the membrane protein surface. The simulations confirms the behaviour of this peptide observed in vitro and shows that it could be used instead of detergents. [less ▲]

Genome-wide gene-environment (GxE) and gene-gene (GxG) interaction studies share a lot of challenges via the common genetic component they involve. GWEI studies may therefore benefit from the abundance of methodologies that are available in the context of genome-wide epistasis detection methods. One of these is Model-Based Multifactor Dimensionality Reduction (MB-MDR), which does not make any assumption about the genetic inheritance model. MB-MDR involves reducing a high-dimensional GxE space to GxE factor levels that either exhibit high or low or no evidence for their association to disease outcome. In contrast to logistic regression and random forests, MB-MDR can be used to detect GxE interactions in the absence of any main effects or when sample sizes are too small to be able to model all main and GxE interaction effects. In this ongoing study, we demonstrate the opportunities and challenges of MB-MDR for genome-wide GxE interaction analysis and analyzed the difference in prebronchodilator FEV1 following 8 weeks of inhaled corticosteroid therapy, for 565 pediatric Caucasian CAMP (ages 5-12) from the SHARE project.

Intravenous artesunate is the treatment of choice for severe and complicated malaria according to the WHO 2010 guidelines. Seventeencases of delayed hemolysis after parenteral treatment with artesunate have been recently reported in European travellers with imported Plasmodium falciparummalaria1. We report the case of a 40-years-old Belgian man who contracted severe falciparum malaria after a four-weeks stay in Central and Eastern Africa without taking any antimalarial chemoprophylaxis. He presented on admission with fever, headache, jaundice andabdominal syndrome.Thereafter hisbiological and clinical conditionrapidly worsened withconsciousness disorders, severe thrombocytopenia,acute hepatitis and pancreatitis, and renal failure. Parasitemia reached a peak of 37 % on the second day of admission. Since this patient fulfilled WHO 2010 criteria for severe malaria,intravenous artesunatetreatment dosed at 2,4 mg/kg was started. Parasite clearancewas obtained after 48 hours and the patient’s clinical status improved significantly.Five doses of intravenous artesunate were administered, followed by oral artemeter/lumefantrine treatment during 60 hours. Tendays after the first dose of artesunate the patient developed a severe hemolyticanemia(hemoglobin4,9 g/dL) associated with impaired renal function. Thick blood film was negative. Blood transfusion and high doses of corticosteroids were successfully administrated and hemodialysis was not necessary. Until now, no clear explanation has been given to this complication. This case highlights the usefulness of extended follow-up including haematological parametersforpatients treated with artesunate, at least one monthafter the malaria episode. 1Published reports of delayed hemolyticanemia after treatment with artesunate for severe malaria--worldwide, 2010-2012.

J’ai voulu identifier les implications possibles de la phénoménologie de la vie perceptive développée par R.G. / dans le champ de la philosophie pratique – et en particulier dans le champ de la théorie de l’art (puisque comme le laissent entrevoir les exemples très stimulants choisis par R.G., ces implications sont à mon avis très importantes – aussi importantes que celles qui ressortent de l’anthropologie philosophique ou la philosophie sociale). Thèse : chaque acte perceptif contient en lui la possibilité pour le sujet d’éprouver une intrigue subjective radicale, celle de l’expérience perceptive elle-même vécue comme conflit (débat affectif). Certains objets / certaines formes (artistiques, par ex. – on pense à la montagne Sainte-Victoire peinte par Cézanne, ou à L’homme qui marche de Giacometti) révèlent le conflit interne à la perception, quand d’autres le neutralisent. Certaines expériences augmentent chez le sujet le désir d’être affecté, d’autres affaiblissent cette « affectibilité » du sujet. Ou encore : selon que l’on en fasse tel ou tel usage, la perception peut soit accroitre le désir de vivre, soit l’affaiblir. Etc. Les formules qui jouent sur ces degrés d’intensité sont multiples. Cette thèse posée, la première question qui me vient est très simple (mais elle m’a accompagné pendant toute la lecture) : qui porte la responsabilité de cet accroissement ou de cet affaiblissement ? Doit-on considérer que le sujet qui perçoit porte la responsabilité de l’intensité et de la densité des expériences de perception qui l’animent ? Ou bien : doit-on considérer que certaines situations (ou certaines expériences) extérieures – éventuellement favorisées par l’action humaine – sont plus avantageuses que d’autres quant à l’énigme qu’elles révèlent ? Dans le champ de la réflexion sur l’art, on se demande alors si on pourrait établir à partir de ces propositions phénoménologiques une normativité qui définirait les conditions artistiques d’une expérience esthétique forte. La question deviendrait alors : une telle expérience dépend-elle d’un usage particulier que ferait le sujet de son pouvoir perceptif (sujet qui aiguiserait sa vigilance, qui serait aux aguets, qui pratiquerait des exercices, qui travaillerait à réveiller en lui ce pouvoir) ou du soin accordé par l’artiste (par le producteur) à activer l’imaginaire du spectateur pour densifier (de l’extérieur cette fois) l’acte perceptif ? L’ouvrage n’apporte (évidemment) pas de réponse définitive à cette question (il ne s’engage pas dans une voie unique). Il me semble qu’il y a au moins deux voies possibles (non exclusives l’une de l’autre) proposées par R.G. Comme elles ne sont pas toujours explicitées (elles semblent parfois rivales et parfois complémentaires), je voudrais lui soumettre pour voir s’il s’y reconnaît. (1) Voie éthique : La première manière de développer une normativité qui serait adossée aux conclusions de tes recherches consisterait à établir une sorte d’« éthique » du sujet percevant (et par extension : une éthique du spectateur) – éthique au sens de Spinoza : le critère qui permet de sélectionner/favoriser telle ou telle attitude est celui de l’accroissement ou de la diminution du sentiment de la vie. Le sujet idéal serait dans cette perspective celui qui prend des risques dans son rapport aux œuvres (auditives ou visuelles), qui ne cherche pas à atténuer à tout prix le conflit perceptif. Il laisse l’œuvre mettre son corps en conflit. Plusieurs passages très stimulants décrivent en ce sens l’engagement (physique) du sujet qui cherche une attitude motrice, une posture ou un geste qui lui permette de tenir et de donner forme au conflit interne fondamental qui l’affecte dans l’épreuve perceptive. Ceci – dis-tu quelque part – par un travail technique et affectif. C’est l’exemple du pianiste (personnage qui est né – pour nous en tout cas – à Liège) qui redresse le dos (le spectateur des sculptures de Giacometti aussi redresse son dos). Trouver les usages qui intensifient la rencontre. (2) Voie critique : mais on pourrait aussi développer à partir de là – d’autres passages le suggèrent : on sent que R.G. est tenté aussi par cette deuxième voie – une critique de la culture contemporaine (au sens fort de la Kulturkritik). C’est-à-dire – pour reprendre le vocabulaire de la Théorie critique, qui n’est pas tout-à-fait celui de R.G. mais qu’il pourrait rejoindre à mon avis - une critique de la culture industrielle qui chercherait à adapter ses productions aux attentes du récepteur et qui fabriquerait donc des produits sans négativité, suscitant immédiatement des réponses adaptées et évitant la crise. De tels produits – des objets « dont l’énigme est minimale » – sont par là-même susceptibles d’appauvrir l’expérience perceptive, notamment parce qu’ils renvoient le spectateur à son assurance plutôt qu’à sa vulnérabilité (et donc à sa liberté). Cette critique de la culture me semble exister par endroit chez R.G. qui regrette/dénonce par exemple un « usage fonctionnel de la perception » favorisé par « nos sociétés ». Ou : la production d’objets que l’on « digère »/consomme trop facilement parce qu’ils sont dépouillés de toute densité. Ou : un mauvais usage de l’imaginaire qui désincarne les sujets, c’est-à-dire qui n’entretient pas ce lien qui fait qu’on se sent concerné par les choses, engagé/regardé par elles (un usage donc qui distrait les sujets ?). Je me demande même si on ne pourrait pas revisiter à partir des recherches de R.G. le thème de la distraction (générée par la culture industrielle). Cf. notamment autour de la page 410 – sur « le culte contemporain d’une liberté qui ne se laisse pas entraver par ce qui lui fait obstacle, qui est capable de ne pas rester attachée à ce qui lui résiste de trop, qui est capable de ‘ne pas se faire trop de soucis’ ».

Root uptake and its relation to environmental factors, and primarily soil water content, are perhaps the least understood component in terrestrial water balance and is of high importance for water resources management, ecology and agriculture. In this research we explore the spatial and temporal distribution of soil water in high resolution using electrical resistivity tomography (ERT). Bell peppers were planted in a chamber and irrigated in two different schemes, differing only in irrigation frequency (daily and eight-daily irrigation, where the daily dose is equal for both treatments). This irrigation difference results in very different spatio-temporal distribution of the soil water in the root zone, which in turn derives spatio-temporal differences in root uptake. Experiment was conducted under a screen-house in Mediterranean summer conditions, i.e. very high evapotranspiration. Resistivity surveys, using 96 electrodes placed around the growth chamber and at soil surface (Figure 1) were taken over 10 times daily. Plants subjected to high frequency irrigation generally were faster in growth and matured about a week earlier. This is primarily attributed to the higher water content that exists in the root zone, and primarily during the climatically stressing noon hours. Inverted images (e.g. Figure 2) provide an interesting insight into the spatio-temporal distribution of the root uptake. This in turn can now be correlated to the spatial location of the roots, and to the soil induced water content dynamics. [less ▲]

Epistasis is likely to underlie most complex traits, including gene expression, yet it is very difficult to detect using standard approaches. SNPs located inside a gene coding region or in its vicinity (i.e. ≤2 Mb from each 5’ and 3’ side) can influence the corresponding gene expression levels. These expression quantitative trait loci (eQTLs) are referred to as cisSNPs. In contrast, eQTLs that are outside the aforementioned gene range can also influence the gene’s expression, in which case, they are called transSNPS to that gene. In this study we considered significant cisSNPs previously identified via generalized least squares (GLS) regression modeling. We then identified those genes transcripts whose expression is regulated by cis/transSNP interaction. In this work we aimed at identifying transcripts whose expression is regulated by a cis/transSNP interactions using Model-Based Multifactor Dimensionality Reduction (MB-MDR) [2]. This model-free approach to detect trans-epistasis involves reducing a high-dimensional GxG space to GxG factor levels that either exhibit high evidence, low evidence or no evidence at all for their association to gene expression levels of interest. Our protocol was applied on real-life data from the childhood asthma management program (CAMP) [1]. It involved coupling a traditional a priori eQTL search to an a posteriori trans-epistasis analysis to identify genetic modifiers to statistically significant cisSNPs. Such an approach allows to reveal previously unreported inter-dependencies that may be important in understanding of biological mechanisms underlying human complex diseases such as asthma. The proposed protocol identified a large number trans-epistasis gene-gene effects of eQTLs. [less ▲]

The femoral-facial syndrome is usually sporadic and its aetiology remains unknown. Non-genetic factors as maternal diabetes mellitus have been associated. Reports of familial cases have otherwise suggested autosomal dominant inheritance. We report the 20 years clinical follow-up of a girl with femoral-facial syndrome diagnosed at birth. Recently, array CGH investigation identified a 1400 kb duplication at 9q31.1, including the gene SMC2, and a 343 kb deletion at 12q24.33 including the genes CHFR, ZNF26, ZNF140, ZNF10 and ZNF268. Moreover, the patient presents a Mayer-Rokitansky-Kuster-Hauser syndrome diagnosed at puberty. Femoral-facial syndrome and Mullerian agenesis may reflect different defects in the primary axial mesodermal development, being the consequences of same environmental or/and genetic factors during blastogenesis. Among these genetic factors, we suggest the possible involvement of the two copy number variants reported here [less ▲]

Increasing age, several co-morbidities, environmental contamination, antibiotic exposure and other intestinal perturbations appear to be the greatest risk factors for C. difficile infection (CDI). Therefore, elderly care home residents are considered particularly vulnerable to CDI. The main objective of this study was to evaluate and follow the prevalence of C. difficile in a Belgian nursing home. During a 4-month period, stool samples from a group of 23 elderly care home residents were collected weekly. A C. difficile microbiological detection scheme was performed along with an overall microbial biodiversity study of the faeces content by Targeted Metagenomic analysis. Surfaces and diary meals were also sampled in order to determinate the possible role of environmental and food contamination in the acquisition of CDI. Culture of samples was performed in a selective medium cycloserine cefoxitin fructose cholate. An identification of the isolated colonies was done by PCR detection of tpi, tcdA, tcdB and cdtA genes. Toxic activity was confirmed by a cytotoxic immunoassay. Further characterization was performed by PCR ribotyping. The Metagenomic analysis was targeted on the v1-v3 hyper-variable region of 16S rDNA. The taxonomical assignment of the populations was performed with MOTHUR and Blast algorithms. C. difficile was not detected in any of the tested meals or surfaces samples. For the stools samples, 6 of the 23 controlled residents were identified as C. difficile carriers. The isolates belonged to 4 different PCR ribotypes, including types 020 and 027. This unique association of classical microbiology protocol with pyrosequencing allowed to follow C. difficile in patients and to identify several other bacterial populations whose abundance is correlated with C. difficile.
