In the current energy context, many efforts are devoted to the reduction of the energy footprint of buildings. To meet this challenge, the LCIS-GREENMAT laboratory developes a front edge research in the field of advanced materials associated to energy and environment, including structured materials for dye-sensitized solar cells (DSSCs) and electrochromic coatings. DSSCs have been reported by O’Regan and Grätzel in the early nineties as a very promising alternative to conventional photovoltaic silicon devices. Main benefits of these cells are their low cost as well as their mild manufacturing process. In most of the specific literature, DSSCs are made of TiO2 films prepared by doctor-blade or screen-printing of anatase nanoparticles paste. However, due to the random organization of the nanoparticles, pore accessibility by the dye and electrolyte could be incomplete. Moreover, some anatase crystallites could suffer from a lack of connectivity, leading to electron transfer issues. The strategy adopted by our group to improve photovoltaic efficiencies involves a templating-assisted process to prepare highly porous layers with well-ordered and accessible pores as well as improved crystallites connectivity. This talk especially focuses on the templating-assisted synthesis of TiO2 and ZnO semiconducting layers used as photoelectrode in DSSCs. Due to the surface area improvement as well as the perfect control of the pore organization and the pore size, the templating strategy is an effective solution to maximize the adsorption of active dye and the electrolyte infiltration inside the porous network. Besides, in the last few years, there has been increasing interest in electrochromic glazing due to its potential use as an energy-efficient component for buildings, as it could reduce considerably their CO2 emission by decreasing their energy consumption up to 30%. The crucial issues of such devices are the durability, the coloration efficiency and the reversibility upon coloration and bleaching of the electrochromic layers. In order to improve the performances of those electrochromic films, we have investigated a surfactant-assisted deposition process for WO3 layer and the insertion of lithium in the NiO layer. All films have been deposited on FTO glass substrates by ultrasonic spray pyrolysis (USP), which is a low-cost alternative to industrial vacuum processes for manufacturing high quality thin films. The presence of lithium ions in nickel oxide films has shown improved coloration efficiency compared to the undoped films. The higher active surface of surfactant-assisted tungsten oxide films has led to higher reversibility and coloration contrast. [less ▲]

HOME BLOOD PRESSURE IN KIDNEY TRANSPLANT RECIPIENTS (KTR)-Validity of different schedules of self-monitoring A. Saint-Remy, L. Weekers, C. Bonvoisin, P. Xhignesse, B.Dubois, JM. Krzesinski NEPHROLOGY - CHU LIEGE AIM: Office blood pressure (OBP), 24-h ambulatory monitoring (ABPM) and home self- monitoring (HBP) allow assessing BP control in treated HT patients. For HBP, ESH guidelines recommend 7 days of measurements but that duration is questioned. The present study analyzed the agreement between daytime ABP and different schedules for HBP in 70 treated hypertensive KTR. METHOD: BP control defined by OBP <140/90 and daytime ABP or HBP <135/85 mmHg was tested in 70 KTR (mean age 56 ± 11 y; mean graft survival 7 ± 6.6 y). OBP and HBP were measured with an Omron M6 and 24-h ABPM with a Spacelabs 90207. HBP was measured on consecutive days (2 times in morning and 2 times at evening/day), the first day was discarded for the mean calculation. Agreement between daytime and HBP was studied when HBP was measured during 7, 5 or 3 days. RESULTS: BP was uncontrolled in 50% of the KTR based on OBP, in 61 % according to daytime ABP and even in 64 % with HBP. Sensitivity (Se) testing agreement between daytime ABP and HBP decreased progressively when number of days was shortened: the highest Se was observed for a 7 days duration with 1st day discarded (86 %). Specificity (Sp) fluctuated around 70 % and was the highest for a 5 (73 %) and 3 days schedule. However the 5 days schedule had higher Se (83 %) than the 3 days. Proportions of KTR correctly classified according to daytime ABP were 79 %, 79 % and 78 % with the 7, 5 or 3 days schedule, respectively. CONCLUSIONS: HBP, easier and less restricting method than 24h ABPM, is a good alternative to daytime ABPM as nearly 80 % of treated KTR were similarly classified. HBP recording period can be shortened to 5 days according to Se and Sp. A 3 days schedule seems more risky reducing the chance to identify masked HT due to a decreased drug adherence. [less ▲]

For the 10 last years, terrestrial and satellite (GRACE) gravity measurements have reached such a precision that they can be of interest to better monitor underground water masses. First, we show that terrestrial measurements provide high-precision information about the time evolution of mass changes in the few kilometres square around the gravimeter. Then, examples of the possibilities and limitations of terrestrial measurements are given in Membach, close to Eupen, and in the Rochefort karst system. In Membach, we show that the evapotranspiration can be directly inferred from continuous gravity measurements: as water evaporates and transpires from terrestrial ecosystems, the mass distribution varies through the system, changing its gravity field at the level of, or smaller than 10-10 g per day. This corresponds to 2.0 mm of water over an area of 50 ha. The strength of this method is its ability to ensure a direct, traceable and continuous monitoring of actual ET for years at the mesoscale (~50 ha) with a precision of a few tenths of mm of water. In Rochefort, gravity measurements at the surface and in the cave allows separating the water contained in the unsaturated zone from the saturated one and therefore monitoring groundwater content changes that occur in the unsaturated zone only.

Perinatal brain injury is a major contributor to neonatal morbidity and mortality and is a common cause of disability with devastating impact on individuals and families. The mechanisms involved in the genesis of brain lesions depend of the the gestational age at which brain development is altered. In the term infant, the most common pathology implicated in brain damage is hypoxic-ischemic encephalopathy (HIE). HIE is the consequence of an excitotoxic cascade leading to cortical and/or basal ganglia lesions. Therapeutic hypothermia induced in the 6 hours following HIE reduces the risk of death or major neurodevelopmental disability in the neonate with moderate or severe encephalopathy and is the only neuroprotective treatment available in clinical practice. Research is now being focused on other promising strategies such as xenon, allopurinol, N-acetyl cystein, melatonin, anticonvulsant, erythropoietin or stem cell transplantation. In the preterm infant, diffuse white matter injury (dWMI) is the main pathological condition associated with neurological impairment. Based on experimental models, pathophysiological mechanisms of dWMI potentially include infection/inflammation, hypoxia-ischemia and oxidative stress. Experimental studies suggest a sensitizing effect of systemic inflammation that makes the perinatal brain more vulnerable to further insults. Antenatal magnesium sulfate therapy given to women at risk of preterm birth substantially reduced the risk of motor disorders in childhood but is unfortunately unable to reduce long term cognitive impairment or behavioural disorders. Antenatal steroids and caffeine therapy for apnea of prematurity are two other treatments with positive impact on neurodevelopment. Randomized controlled trials studying erythropoietin or melatonin are currently under process. Finally, research performed at the University of Liege suggests that Estetrol (E4), an estrogen synthetized exclusively by the human foetus, has neuroprotective properties in animal models of HIE as well as in inflammatory-induced dWMI.

A pseudo-Boolean function is a real-valued function of 0-1 variables. Every pseudo-Boolean function can be represented by various analytical expressions, e.g., as a polynomial in its variables, or as a polynomial in its variables and in their Boolean complements, or as a disjunctive form, or as pointwise minimum of a family of affine functions, and so forth. Motivated by the problem of minimizing pseudo-Boolean functions, we consider yet another class of representations. Namely, we say that g(x,y) is a quadratization of the pseudo-Boolean function f(x) if g(x,y) is a quadratic pseudo-Boolean function of x and of m auxiliary binary variables y such that, for all x, f(x) = min g(x,y), where the minimum is taken over all possible values of the y-variables. It can be shown that every pseudo-Boolean function has at least one, and usually, many quadratizations. In recent years, several authors have proposed to reduce the problem of minimizing an arbitrary function f(x) (say, expressed as a high-degree polynomial) to the (presumably easier) problem of minimizing one of its quadratizations. In this talk, we discuss the size of ``small'' quadratizations, that is, the number of auxiliary variables required in any quadratization. We provide lower and upper bounds on the number of auxiliary variables for the case of an arbitrary function f(x), as well as for the special case where f(x) is a symmetric function of its variables.

Une des priorités contemporaines en éducation scientifique est d’envisager une utilisation des acquis de la recherche en didactique des sciences pour la formation afin que la recherche qui parle des pratiques d’enseignants parle également aux enseignants. Les formateurs ont, dans cette perspective, un rôle de passeurs à jouer. Il serait utile de définir les conditions nécessaires pour que les apports des chercheurs deviennent un éclairage usuel du praticien. Ces conditions sont relatives au mode d’accompagnement et à la posture du formateur; au contenu de la recherche elle-même; au parcours de l’enseignant; aux attentes prescrites… C’est par l’analyse d’exemples vécus d’intégration réussie, ou non, d’apports de la recherche dans la construction de réponses à des questions d’ordre didactique par des enseignants en formation, que nous tenterons de repérer des conditions favorables à une telle intégration.

The State archives in Liège preserve some of the 16th century “fabrique“ accounts of the Saint Denis collegiate church of Liège. Among them, accounts of the year 1533 drew the attention of Jean Yernaux in his 1958 study about Lambert Lombard. Indeed he found what he thought to be the proof of the Liège Renaissance Master’s intervention in the painting of the Saint Denis Altarpiece panels, before giving up the attribution in 1970. Since then, these two mentions have been used to illustrate either the involvement of Lombard or of another painter named “Lambert” in the painting of the panels. But looking closer at the original document, it is obvious that Yernaux committed huge mistakes in the transcript of these mentions. Not only was he wrong about the sums paid to the artist but also about the work mentioned in this account. In order to understand this document fully and correctly, it is therefore essential to propose a transcription from which new interpretations can be generated. This new understanding can then lead to further contextualization of the mentions. These accounts need to be looked at in close relationship with the rest of the document. This would shed new light on the writer’s habits, especially when it comes to designate individuals. The amount of money given to the painter Lambert also needs to be assessed. Comparisons to other payments of the same period conserved in the archives of the Saint Denis church and of other churches in or around Liège are going to be unveiled and investigated. This will give interesting clues to understand better the extent of the work done by the artist as well as his social status. [less ▲]

Dans les matériaux de construction, la notion d’environnement et d’empreinte des produits devient de plus en plus importante que ce soit dans un cadre législatif ou comme objet de marketing. Dans ce contexte, des études environnementales ont été réalisées sur divers produits belges en pierre bleue (dalles, bordures, marches) ainsi qu’en grès (pavés). Ces études ont été menées en utilisant la méthodologie de l’Analyse du Cycle de Vie (ACV) et ont permis de mettre en évidence les étapes prépondérantes de leur production dans une optique d’écoconception ainsi que de les comparer à d’autres produits sur le marché tels que leurs concurrents asiatiques. Les frontières du système comprennent les étapes depuis l’extraction des matières premières, en passant par la production des produits finis ainsi que leur transport sur chantier situé en Belgique. Cette présentation reprend le pourquoi et le comment d’une Analyse du Cycle de Vie, les différentes étapes nécessaires à l’application de l’ACV aux produits en pierre belge ainsi que les principaux résultats. Cette présentation permettra la mise en évidence de l’intérêt de l’ACV et des fiches de déclaration environnementale qui y sont associées ainsi que les perspectives qui peuvent en découler dans le domaine des matériaux et plus précisément pour les matières minérales.

Les spécificités et les difficultés de la « lecture pour apprendre » au début du secondaire sont à l’origine du projet de recherche longitudinale de type quasi-expérimental dans lequel s’inscrit notre contribution. « Lirécrire pour apprendre » a pour principaux objectifs d’expérimenter, durant deux années successives (2014-2016), un programme didactique centré sur le développement de la compréhension et de la production des textes à visée informative-explicative ; de tester la valeur de cet outil sur un large échantillon d’élèves du premier degré de l’enseignement secondaire et d’évaluer les conditions d’implémentation et de mise en œuvre de l’outil les plus favorables au changement de pratiques pédagogiques et au maintien de l’innovation. Dans le cadre de cette contribution, à l’issue de la première année de l’expérimentation, nous évoquons quelques éléments de définition et de modélisation préalables (première partie), quelques-uns des constats posés en amont de la conception du programme (deuxième partie) ainsi que le design de la recherche et les caractéristiques du dispositif didactique (troisième partie). Ces éléments constituent le cadre de référence dans lequel s’inscrit l’étude développée dans la quatrième partie du texte, relative aux premiers résultats quantitatifs de l’expérimentation du dispositif. Les données recueillies auprès d’un échantillon de 1690 élèves (scores bruts), limitées aux apprentissages en lecture, sont examinées à la lumière de la question suivante : les élèves peuvent-ils, sous l’influence d’un outil structuré, progresser dans leur capacité à comprendre un texte ou un dossier de documents informatifs-explicatifs et à rendre compte de leur compréhension ? Seule l’évolution des performances des élèves est ici étudiée. Deux autres variables prépondérantes, qui influencent les résultats des élèves, à savoir l’appropriation de l’instrument didactique par les enseignants ainsi que les pratiques effectives d’enseignement, seront analysées ultérieurement, à la lumière de l’ensemble des données de la recherche.

Paraneoplastic hypercalcemia and hypercalcemia associated with neoplastic syndromes are particularly resistant to conventional hypocalcemic treatments. We present and discuss two case reports in which Cinacalcet was used to control hypercalcemia. Paraneoplastic hypercalcemia is present in the first case report, in association with a metastasic neuroendocrine pancreas. In the second case report ,cinacalcet is used to control hypecalcemia in a patient with multiple endocrine neoplasia and hyperparathyroidism not controlled by neck surgery. Cinacalcet is an oral agonist of the Calcium Sensing Receptor. The hypocalcemic effects of Cinacalcet have not been documented so far in hypercalcemia-paraneo plastic linked to cancer of the pancreas (Valdés-Socin & al. Rev Med Switzerland 2009). On the other hand, its use seems promising in the MEN1-associated hyperparathyroidism. (Giusti & al. Endocrine 2015). [less ▲]

Despite growing recognition that the technical and social dimensions of technology development are coproduced, research and policymaking in the nuclear field is still predicated on the separation between both dimensions. This paper explores how this separation is enacted, and occasionally questioned and transformed, within the Belgian context of nuclear technology. It situates the emergence of a science policy support (SPS) unit and programme (PISA) within the Belgian Nuclear Research Centre SCK•CEN as an institutional response to the need of integrating societal and ethical concerns into nuclear research. The paper elicits how since 1999, SPS/PISA draws together science and technology studies (STS) and technology assessment (TA) approaches, creating links between nuclear research innovation and society in mutually beneficial ways. To this end, it first outlines the four areas in which SPS/PISA researchers are active: 1. Ethics of nuclear technology assessment; 2. Radioactive waste management; 3. Safety governance; 4. Perception and communication of ionising radiation risks. As SPS/PISA research is situated in a trading zone that embeds scholarship, nuclear research and research policy, the paper illuminates the growing entanglement of the natural and social sciences, and the roles social scientists play in the development of contemporary technologies and technology policy. Drawing on the notion of hybrid management (Miller 2001), the paper argues that SPS/PISA researchers must develop a language that underlines the interdependency between science, policy, and politics, while acknowledging that actors (policymakers, industry representatives, natural and social scientists, citizens) recurrently draw distinctions between these domains as a means of collectively managing nuclear issues. SPS/PISA research is therefore best understood as boundary work that mediates between various interests, values, and "knowledges." The paper concludes by discussing the key challenges SPS/PISA researchers face while engaging in work of this kind: maintaining professional independence and credibility, ensuring research continuity, and generating both scientific and policy impacts.

This paper investigates the impact of corporate board of directors’ (supervisory) attributes on conditional accounting conservatim in the French, German and British contexts. Using pooled regression model over the period 2009-2012, our findings report that the relationship between corporate board attributes and accounting conservatism is country dependent. First, regarding the board composition, we find that the effect of board size is positive for German firms, negative for French firms and insignificant for British firms. We also document a positive association between board independence and accounting conservatism for British firms. However, we find no evidence of a positive association between employee seats on the supervisory board and earnings conservatism in German context. Second, female seats on board seem to increase conservative reporting in financial statement only for French firms. Lastly, board meeting frequency in French and British firms appears to increase accounting conservatism. As a robustness test, we use an alternative measure of accounting conservatism namely, time–series of earnings changes measure and confirm the previous results. Overall, our results reveal that corporate board affects the financial reporting quality. [less ▲]

This talk focuses on the computation of asymptotic standard errors (ASE) of ability estimators with dichotomous item response models. A general framework is considered, and ability estimators are defined from a very restricted set of assumptions and formulas. This approach encompasses most standard methods such as maximum likelihood, weighted likelihood, maximum a posteriori, and robust estimators. A general formula for the ASE is derived from the theory of M-estimation. Well-known results are found back as particular cases for the maximum and robust estimators, while new ASE proposals for the weighted likelihood and maximum a posteriori estimators are presented. These new formulas are compared to traditional ones by means of a simulation study under Rasch modeling. [less ▲]

Dans les conditions difficiles que doit affronter la Tunisie, soit faire face a l'augmentation de la demande en soins de santé, à l'amélioration de la qualité et à la transition démographique et épidémiologique, la Médecine de Famille représente un atout certain. L'image internationale peu flatteuse de la médecine de famille Tunisienne est présentée au travers de sa présence dans les publications scientifiques. Une série de concepts spécifiques de la Médecine de Famille sont exposés ; la complexité, l'extension de la connaissance, l'incertitude, les différents niveaux de l'action. Leur prise en compte permet d'appeler à un autre regard et à un appel à écrire le métier d'une façon différente. Pour en sortir définitivement avec l'image délétère de ce métier exigeant. [less ▲]

Soumises à une clôture particulièrement stricte – qui impressionne les ecclésiastiques les plus rigoureux –, les annonciades célestes ne peuvent évidemment vivre dans l’isolement absolu inscrit symboliquement au cœur de leur spiritualité. Il en va de leur survie dans des contextes souvent difficiles. Sans nécessairement déroger à leurs règles austères, ces femmes entretiennent des relations suivies avec le « monde » pour divers motifs et dans diverses circonstances. Tout en affichant beaucoup de méfiance à l’égard de la « fréquentation des grilles », elles reçoivent pourtant quantité de visites et nombreux sont ceux qui sollicitent l’accès à leurs parloirs. Des liens s’établissent, depuis les plus attendus jusqu’au plus étonnants. Les annonciades se retrouvent ainsi, bon gré mal gré, au cœur de réseaux sociaux qui servent ou desservent leur cause selon les cas. Loin de se cantonner dans le silence et la passivité, ces femmes deviennent des interlocutrices attentives, voire même des actrices influentes au sein de certains espaces urbains. [less ▲]

Objective Isokinetic tests regularly contribute to the assessment of muscle performance. However, to evaluate an athlete who mainly uses the lactic anaerobic metabolism to perform or in specific pathological contexts, fatigue-resistance protocol could be complementary to short maximal strength evaluation. Although the reproducibility of the protocol has been demonstrated by Bosquet et al. (2010), what about the reproductibility of the measured parameters and various "fatigue index" proposed by dynamometers and used in the clinic and in the literature? Material & method Seventeen subjects, moderately active, performed 30 reciprocal maximal concentric contractions on three occasions with one 7-10 days recovery between each session. The peak torque (PT) and the maximal work (MW) of each repetition computed and subsequently use to compile eleven measured parameters and build forty-four index. The reproducibility of each parameter and index was evaluated through their ICC (2,1), SEM and respective MD. Results The ICC values of the measured parameters for the knee extensors are almost always higher than 0.8 while those for flexor range between 0.7 and 0.8. The ICC values for built "fatigue index" are less than 0.7 and 0.5 respectively for the extensors and flexors. No significant difference was observed between the reproducibility of PT and that of MW (whether for the extensors or flexors or for the measured parameters and "fatigue index"). Discussion In view of the values obtained in our population, it appears that no "fatigue index"or calculated quotient (quotient of the last x repetitions by the first x or accumulated repetitions by the best,...) seems sufficiently reproducible for clinical or scientific use! Only the measured parameters such as the best repetition, total or partial sum have a (very) high or excellent reproducibility and can therefore be used in clinical or research domain.

Objective The aim of this study was to assess the compatibility between dynamometer Biodex System 3 Pro, Con-Trex MJ PM-2 and Cybex Humac CSMI of knee extensors and flexors. Material & method Twenty-one subjects, moderately active, performed three isokinetic evaluation sessions with six to ten days of rest between each. Each of it, performed on a dynamometer in accordance with a different randomized order, included a concentric evaluation (60°.s-1 & 240°.s-1), eccentric (30°.s-1) and fatigue-resistance protocol (30 concentric repetitions maximum 180°.s-1) for the knee extensors and flexors. The peak torque (PT) and the maximal work (MW) of each repetition were recorded, as well as concentric and mixed agonists/antagonists ratios, to measure the compatibility inter-dynamometer two by two through their respective ICC (3.1), SEM and MD. Results For the short maximal strength test, ICC values for the extensors are almost always higher than 0.85 in concentric mode although they don't exceed 0.61 in eccentric mode. The ICC values for the flexor in slow concentric and eccentric mode are above 0.7, 0.75 and 0.8 for pairs Biodex/Cybex, Biodex/Con-Trex and Cybex/Con-Trex. None of ICC value exceeds 0.75 in fast concentric mode for the flexors. The ratios have ICC values lower than 0.6 except concentric ratio at 60°.s-1 for the pair Cybex/Con-Trex (0.83) and mixed ratio for the pairs Biodex/Cybex (0.73) and Cybex/Con-Trex (0.77). The ICC values of the parameters measured during the extensors fatigue-resistance protocol are mostly above 0.8 regardless of the pair of dynamometers considered. The ICC values of these parameters for the flexors are almost all lower than 0.7. Discussion Although the reproducibility of extensors in concentric mode is high, it's important to inform users, whether in clinical or scientific domain, that different dynamometers provide regular incompatible results and we draw attention to the little reproducibility of the agonist/antagonist ratios. Our results justify the establishment of norms for each dynamometers brand in order to interpret, with relevance, the isokinetic test, either for short maximal strength evaluation or fatigue-resistance protocol.

Evolutionary change in body size is a widespread phenomenon in animals. Numerous studies have highlighted evolutionary miniaturization, referring to the evolution of small body size, in various taxa. As other traits shift, decrease in size can be viewed as a morphological novelty that enables colonization of new “adaptive zones” and subsequent diversification (i.e. a “key innovation”). Thus, evolution to small body size is hypothesized to influence lineage, morphological and ecological diversification. Until now, few studies have tested this hypothesis and current supports are mixed. Here, we present a quantitative analysis of the radiation of Pomacanthidae (angelfishes), an iconic coral reef fish family where small taxa, the so called “pygmy angelfishes” of the genus Centropyge, appear to have evolved three-times. If an evolutionary decrease in size has acted as a key innovation during the evolutionary history of Pomacanthidae, we predict that diversification rates would be the highest in clades of pygmy angelfishes. We produced a time-calibrated phylogeny including 67 species, collected ecological data and quantified the body shape of 80 species using geometric morphometrics. Then, we tested the prediction by modelling macroevolutionary dynamics of diversification using the Bayesian Analysis of Macroevolutionary Mixture (BAMM) framework. BAMM results do not support a common macroevolutionary regime for every pigmy angelfish clades. Only the clade Centropyge Xiphypops shows higher rates of lineage and morphological diversification than the other clades of angelfishes. We show that miniaturization has few effects on the rate of diversification. The shifts in the tempo of diversification observed in C. Xiphypops might instead be related to a functional innovation of the feeding apparatus. Using the Pomacanthidae, we illustrate that miniaturization may not be a main factor in triggering increased of diversification rates at the family level. [less ▲]

The bottlenose dolphin (Tursiops truncatus) is a major apex predator and the most common cetacean species found in nearshore waters of South Florida, including the Lower Florida Keys (LFK) and the Everglades National Park (ENP). The objective of this study was 1) to assess contamination levels of total mercury (T-Hg) in skin and persistent organic pollutants (PCBs, PBDEs, DDT, HCH, HCB, DLCs and PCDD/Fs) in blubber samples of bottlenose dolphins from the LFK (T-Hg : nmales = 10; POPs : nmales = 16, nfemales = 8) and the ENP (T-Hg : nmales = 13, nfemales = 9; POPs : nmales = 11, nfemales = 8). T-Hg and POPs were analysed by the mean of Direct Mercury analyser (for T-Hg), GC-ECD (POPs) and GC-MS (DLCs and PCDD/Fs). The PCBs were the main compounds found in bottlenose dolphins from the LFK and ENP. The most present congeners where the CB no. 28, 52, 101, 138, 153 and 180 (Σ 6 PCBs LFK males: 13420.5 ng.g-1 lipids, Σ 6 PCBs LFK females: 9683.4 ng.g-1 lipids, Σ 6 PCBs ENP males: 5637.9 ng.g-1 lipids, Σ 6 PCBs ENP females: 1426.9 ng.g-1 lipids), while the concentrations of DL PCBs remained low for both locations (LFK: 739 ng.g-1 lipids, ENP: 183 ng.g-1 lipids). PCBs concentrations were significantly higher in individuals from the LFK than those from the ENP. PCBs concentrations in LFK and ENP dolphins were significantly lower than those from other locations in the south-eastern US. Unlike organic pollutants, T-Hg concentrations were significantly higher in ENP male dolphins (LFK: 2936.0 ng.g-1 dw, ENP: 10048.3 ng.g-1 dw). These high concentrations were the highest recorded in the south-eastern US and are most likely due to the presence of mangrove ecosystems. This study highlights the complexity of contaminant dynamics (inorganic vs. organic), even at small spatial scales. [less ▲]

Les athlètes de lancer présentent une mobilité passive gléno-humérale de l’épaule dominante spécifique avec une majoration de la rotation externe et une limitation de la rotation interne. La limitation interne semble liée à une raideur capsulo-musculaire postérieure, favorisant les pathologies de l’épaule sportive. Matériel et méthodes Vingt hommes, sportifs d’armer / lancer (volley-ball, handball) et pratiquant au moins 6 heures d’entraînement depuis plus de 5 années ont participé à cette étude. Ils présentaient tous une raideur des structures postérieures évaluée en clinique. Lors de l’inclusion dans l’étude, 10 athlètes (22,5 ± 4 ans) étaient asymptomatiques, 10 (24,8 ± 4 ans) présentaient une épaule dominante symptomatique (≥ 3/10 sur l’EVA). Les athlètes ont étiré chaque jour leur épaule dominante (sleeper stretch et cross body arm) pendant 4 semaines (5 x 30’'). Avant et après le programme d’étirement des structures postérieures, ils ont subi un test isocinétique de force maximale des rotateurs internes et externes ainsi qu’une analyse tridimensionnelle définissant la cinématique scapulaire. Résultats Après 4 semaines d’étirement des structures postérieures, tous les athlètes ont montré un gain significatif de mobilité en rotation interne passive. Nous n’observons aucune modification de la cinétique scapulaire lors de l’analyse 3D après les étirements chez les athlètes asymptomatiques ; les athlètes symptomatiques présentent une diminution du tilt antérieur scapulaire au repos après les 4 semaines. L’évaluation isocinétique des rotateurs d’épaules après les étirements montrent uniquement une légère réduction (- 4% ; p < 0,05) de la force des rotateurs internes à 60°/s en concentrique chez les athlètes asymptomatiques. Les sportifs qui décrivaient des douleurs avant les étirements sont significativement améliorés après le programme de 4 semaines ; cette diminution de la douleur est corrélée au gain en rotation interne passive. Discussion L’étirement pendant 4 semaines des structures postérieures de l’épaule raide sportive permet une augmentation de la mobilité passive. Ce gain de mobilité est corrélé à la diminution de la douleur chez les athlètes symptomatiques. [less ▲]

Polyspecific seagrass meadows are of critical ecological importance in tropical coastal zones. These ecosystems provide a wide range of socio-economical services to local populations. Meadows however undergo multiple threats linked to human activities (increased nutrient input, overfishing, invertebrate overharvesting, etc.). It is currently difficult to assess how seagrass meadows could respond to anthropogenic impacts due to poor knowledge of their functional ecology. Here, stable isotope ratios of carbon, nitrogen and sulfur were used to unravel trophic interactions ruling the food webs associated to seagrass beds of the Toliara Great Reef (SW Madagascar). The contributions of various potential food items (sediment-associated and suspended particulate organic matter, plankton, leaves, roots and epiphytes of 7 seagrasses and thalli of 7 dominant macroalgae) to the diet of 20 invertebrate taxa (one sea urchin, 2 sea stars, 2 sea cucumbers, 5 gastropods including one sea hare, one bivalve, 2 amphipods, one leptostracan, one cumacean 2 hermit crabs and 3 shrimps) were assessed using a Bayesian stable isotope mixing model. Model outputs revealed that important trophic diversity existed among the invertebrate assemblage. In some groups (e.g. hermit crabs and amphipods), resource use by morphologically and taxonomically close taxa was markedly different. Many of the dominant taxa heavily relied on macroalgae for their nutrition. On the other hand, few species apparently consumed seagrass tissues. Moreover, when they did, seagrass generally accounted for a minor portion of the diet only. Overall, our results suggest that seagrass grazing in meadows of the Toliara Great Reef could be lower than in other tropical areas. These discrepancies could be linked with seasonal variation in resource availability or with eutrophication. Higher nutrient load is indeed known to cause ecosystem phase shifts and it may induce diet shift to algivory in some invertebrate consumers. [less ▲]

OBJECTIVE: Cardiac surgery may be complicated by acute kidney injury (AKI). Cardiotomy suction during cardiopulmonary bypass (CPB) is deleterious. A few studies have demonstrated that shed mediastinal blood (SMB) suction during cardiopulmonary bypass (CPB) can increase inflammatory response and lipids emboli. These 2 factors contribute to the development of postoperative AKI. The RemoweLL (RemoweLeucoLipids, Eurosets™, Italy) filter is a recent designed cardiotomy with a multilayer filter for activated leucocytes filtration and a syphon for lipid particles sequestration. The SMB can be collected and filtered in this supplementary cardiotomy added to CPB circuit. The aim of this monocentric prospective study was to compare the specific RemoweLL cardiotomy filtration for suction blood during CPB and a conventional 40 µm filter (Admiral, Eurosets™, Italy). The primary goal was to evaluate the AKI within 48 hours after surgery using the Acute Kidney Injury Network classification (AKIN classification) but also measuring early specific biomarkers of AKI: serum Cystatine C and urinary neutrophil gelatinase-associated lipocalin (NGAL). METHODS: Sixty patients scheduled for elective cardiac surgery (aortic or mitral valvular combined or not with coronary bypass grafting) with a glomerular filtration rate (GFR) > 45mL/min. were randomly into 2 groups for SMB filtration: - Groupe 1 (n=30) with RemoweLL cardiotomy (Leucocytes and lipids filter); - Groupe 2 (n=30) with Admiral cardiotomy (conventional 40 µm filter). All components: venous reservoir, oxygenator and surface treatment were similar in both groups. [less ▲]
