Dans les années qui suivent leur établissement en milieu urbain, les religieuses sont amenées à aménager puis à ériger des bâtiments conventuels conformes à leurs besoins et à leur mode de vie. Malgré la stricte clôture que leur impose le concile de Trente, les religieuses se doivent de faire appel à des professionnels du bâti et de passer des contrats avec une main d’œuvre généralement masculine, qu’il s’agisse d’architectes, d’entrepreneurs ou d’artisans. Cette communication propose d’analyser la manière dont différentes congrégations religieuses implantées sur la « dorsale catholique » (annonciades célestes, bénédictines de la Paix Notre-Dame, ...) sont parvenues à recruter ces hommes de terrain, à guider la conception du plan, à surveiller le déroulement du chantier et le cas échéant, à affirmer leurs compétences. Dans un premier temps, sera analysé le discours normatif des règles et constitutions qui encadrent ces rapports avant de les confronter, dans un second temps, aux témoignages et au vécu de ces femmes livrés par leurs écrits (chroniques, annales, biographies de religieuses) aux XVIIe et XVIIIe siècles, inédits pour la plupart.

Temperate forests, as other ecosystems and oceans, mitigate the accumulation in the atmosphere of CO2, the main responsible for the current climate change. It is, therefore, a necessity to understand how these forests react and will react in a changing environment. That requires long-term simultaneous monitoring of the forest productivity and phenology as well as of climatic variables. Using the 20 years dataset from the Vielsalm Terrestrial Observatory (VTO), an eddy covariance site located in a mixed forest in east Belgium and dominated by beeches, the relations between phenological and productivity indicators were analyzed. Phenological indicators (leaf out beginning, duration and ending as well as leaf fall date) were derived from the relative light transmissivity through the canopy and from the temporal dynamic of the Net Ecosystem Productivity (NEP). No trend was observed for these indicators during the last two decades, but significant relations were found between them and between them and climatic variables. Productivity indicators were derived from eddy covariance measurements (NEP), tree ring widths (growth index) and masting intensity. Growth index was significantly related to the NEP and a reverse proportionality to the masting intensity was found. The analysis of the relation between the beech stand NEP and the phenology gives us evidences that annual NEP is significantly related to the length of the carbon uptake period. A model combining the length of the carbon uptake period and the photosynthetic capacity of the ecosystem was able to predict more than two third of the interannual variability at the VTO. This work underlines the multiplicity of the relation between phenological and productivity indicators. [less ▲]

Despite the growing interest for oxygenated volatile organic compounds (OVOC) over the last 15 years due to their role in the atmospheric chemistry, current knowledge about OVOC exchanges by grassland and the environmental factors driving them remains lacunar. However, those ecosystems represent an important part of the total earth surface (13.37%). This study conducted on a grazed grassland therefore aims to quantify OVOC exchanges over full grazing seasons in order to understand the mechanisms behind these exchanges. It took place within the activities of the CROSTVOC project (CROp Stress VOC) and therefore gives an important attention to the stress induced fluxes. BVOC flux measurements were performed with a PTR-MS for the measurements of OVOC mixing ratios on two different scales: the eddy Covariance method was used during two whole grazing seasons (2014 and 2015) and in the 2016 summer, measurements were also performed on a smaller scale by using all-teflon automated dynamic chambers. The chambers allowed measuring accurately the impact of grazing by following simultaneously undisturbed and grazed grassland patches. This study pointed out that several OVOC were exchanged in variable quantities, with methanol being by far the most important. Methanol fluxes exhibited a clear diurnal cycle with close-to-zero fluxes at night and maximum fluxes at midday. The flux was also much larger in the summer than during autumn or spring. For the eddy Covariance data, the average methanol flux in the summer (0.033 μg.m-2s-1) was in the same range of other studies, being lower than the average found by Bamberger et al. in 2010 (0.080 μg.m-2s-1) and by Ammann (0.077 μg.m-2s-1). Fluxes from the chambers were slightly lower with an average value of 0.27 μg.m-2s-1 but they were measured in the late summer. Driver analysis is still ongoing but first results showed that the flux was strongly correlated at short time scale (half hourly for the EC method and one and a half hourly for the chambers) to the photosynthetic photon flux density and the latent heat flux. We believe that their influence comes mainly from the control practiced by stomatal conductance in non-steady state conditions and expansion of cell walls in steady state conditions. The cuvette data showed that grazing resulted in significantly enhanced emissions of methanol that lasted for several days. On the contrary, the eddy Covariance method cannot distinguish between grazed and non-grazed grass and only a small fraction of the method footprint had been grazed the previous days on average. Our eddy-covariance data suggested that an increase in the stocking density did not contribute to a significant rise of methanol emission. The limited variability in stocking density during the two growing seasons and the more powerful effect of other drivers likely induced that the flux variability due to the SD was too low to be measured by the eddy Covariance method. In depth comparisons between the eddy-covariance data and the dynamic chambers data will be carried out. [less ▲]

Nous décrivons ici le cas d’un patient de 21 ans atteint d’hyperoxalurie primaire de type I suivi depuis 2015 au CHU de Liège. Le diagnostic a été confirmé chez le patient dès ses 3ans par test génétique. Les mutations en cause sont c.969-3C>G et c.725C>A, laissant une activité résiduelle de l’alanine glyoxylate aminotransférase estimée à 3%. L’oxalurie de 24h était comprise entre 100 et 170mg/g de créatinine lors des dernières biologies. Le traitement médicamenteux inclus de la pyridoxine (2x250mg/j) et du citrate de potassium (+/-10g/j). Une sonde de gastrotomie a également été instaurée pour gavage hydrique nocturne. Le patient a subi plus de 12 interventions urologiques au cours des 3 années précédentes. Aussi, la fonction rénale a progressivement décliné en passant de >60 à 40mL/min/1.73m² notamment à cause de la compliance difficile au traitement. Aucune manifestation extrarénale de l’oxalose n’est encore survenue. L’analyse infrarouge des calculs de 2015 et 2016 renseignaient une composition exclusive de Whewellite. L’analyse morphologique identifiait initialement des calculs de type Ia, mais plus récemment, ceux-ci ont commencé à prendre une structure inhabituelle moins organisée. Les derniers calculs expulsés en 2017 présentaient quant à eux un faciès bien particulier avec de grands cristaux anguleux aux angles non quadratiques. L’analyse infrarouge a permit de détecter la présence de Caoxite (oxalate de calcium trihydraté) au sein de deux séries de calculs. En guise de confirmation, une étude de la cristallurie a mis en évidence des cristaux au faciès typique de la caoxite. La formation de ces calculs particuliers pourrait être associée à plusieurs éléments, comme la prise de bicarbonate de calcium accompagnée d’une hypercalcémie (malgré une calciurie basse inférieure à 3mg/24h). Aussi, la baisse de la fonction rénale et une augmentation de la citraturie de 24h étaient concomitants. Par contre, aucune augmentation significative de l’oxalurie n’a pu être observée. Les mécanismes précis ayant menés à la précipitation de caoxite restent flous, sachant que ce composé n’a à notre connaissance, été décrit que lors de la prise de glyoxylate. [less ▲]

Objective: Poor quality medicines regrouping counterfeit/falsified, sub-standards and degraded are a scourge for developing countries (1). Their public health consequences are often observed for cases of low dosage of active ingredients and sometimes for the absence of these. On the basis of the observed facts as well as suspected reported cases, we were interested in deepening the information through laboratory tests. Methods: Liquid chromatography (LC), thin layer chromatography (TLC), nuclear magnetic resonance (NMR), mass spectrometry (MS), Raman imagery (Rim) and near infrared spectroscopy (NIR) were used as targeted analytical techniques in this study, associated with the principal component analysis (PCA), while the suspect samples were obtained via the public health authorities of the DR Congo, Benin and Rwanda after their seizure. Results: The observed cases are presented by therapeutic class, namely: - analgesics: (1) cases of tablets supposed to contain paracetamol and which have caused abnormal adverse effects in patients who have consumed it, namely sedative effects, polyuria and hypotension. Using LC and complementary surveys by people interview, we were able to demonstrate the presence of a benzodiazepine and at very high doses. (2) Cases of paracetamol syrup whose excipient (glycerol) was substituted by diethylene glycol and which had caused the death of a hundred babies. Using the NIR and the PCA, we were able to elucidate this substitution. - antimalarials: (case 1) cases of arthemether-lumefantrine tablets which had no therapeutic effect. By means of TLC and LC, the absence of these two active ingredients was clearly demonstrated, but the presence of starch was revealed by Rim. (Case 2) case of quinine tablets that had no expected pharmacological effect. The use of several combined techniques (TLC, LC-MS, NMR and Rim) made it possible to demonstrate the presence of a substance with an imidazole structure (antamoeba). - antibiotics: (1) amoxicillin powder which after reconstitution in hospital caused poisoning of the babies until death for some. The reconstitution of the suspension had revealed the misuse of hydrogen peroxide instead of distilled water. (2) Finally a large-scale study (80 samples of amoxicillin powder) showed that 8% of the samples were above the claimed dosage. Conclusion: The cases presented indicate that there are effectively poor quality medicines and that they are responsible of public health problems and in particular of toxicity. Appropriate measures should be taken to protect users. [less ▲]

Au cinéma, le conte s’est exemplairement exprimé sous la forme de l’animation, et plus précisément du dessin animé. Les contes européens fournissent en effet un réservoir considérable de scénarios et de personnages aux réalisateurs de dessins animés, et ceci depuis les débuts du cinéma d’animation (S. Denis, 2015). Cette utilisation du conte se révèle particulièrement intensive dans les dessins animés américains (cartoons) des années 1940 et 1950. Ces cartoons sont alors produits à la chaîne par les studios et diffusés dans les salles de cinémas à côté des films et des actualités. Les studios Disney, ainsi que ceux de la Warner et de la MGM (où officie Tex Avery) emploient ainsi massivement le conte, mais non sans en actualiser les modalités de manières fort différentes. Or, ces utilisations diverses du conte ne sont pas sans conséquences esthétiques plus larges. Ainsi, si les studios Disney voient généralement dans le conte l’occasion de développer un univers merveilleux à la morale traditionnelle, Tex Avery (et, dans une moindre mesure, les réalisateurs de la Warner) limite généralement son utilisation à quelques clins d’œil à la culture populaire ou à une structure narrative connue. Cependant, cette actualisation apparemment superficielle du conte par les concurrents de Disney répond également à une logique d’opposition esthétique : le conte ne peut être pris au sérieux car il est l’instrument de l’ennemi. Les torsions subies par les différents éléments du conte dans les dessins animés de Tex Avery ou de plusieurs réalisateurs de la Warner visent en effet à critiquer directement une certaine manière de faire du cartoon. Les productions des studios Disney étant jugées par leurs concurrents comme mièvres et idiotes. L’univers esthétique et narratif du medium tout entier est ainsi en jeu dans l’utilisation qui est faite du conte, c’est du moins ce que nous essayerons de montrer. [less ▲]

Microbial translocation is now viewed as a central event in the pathogenesis of chronic inflammation during HIV infection. Thymic function failure is another crucial factor involved in HIV disease progression. The goal of this study was to explore the hypothesis of potential links between microbial translocation and thymic function in HIV-1 patients living in Belgium. The extent of microbial translocation was assessed through the measurement of soluble CD14 (sCD14). T-cell receptor excision circles (sjTRECs and dβTRECs) were used as a measure of thymic function. Data were collected from 75 HIV-infected patients. Simple and complex linear regressions were done to analyze the link between these two processes. We found a statistically relevant negative correlation between thymopoiesis (sjTREC) and sCD14 level (p = 0.004). These results suggest a link between thymic function failure, microbial translocation and innate immune activation. [less ▲]

PCR, performed on LIM enrichment broth compared wit the reference method, that is subculture on selective differential agar performed from the same incubated Lim broth inoculated with a vagino-rectal swab collected at 35-37 weeks’ gestation. Material/methods: During an 8-months period in 2015-2016, series of consecutive vagino/rectal swabs collected for antenatal GBS screening (at the university hospital of Liege, Belgium) were plated first on Granada agar and then inoculated in selective enrichment LIM broth. The incubated broth was further sub-cultured on Granada and Biorad StrepBselect agars. Moreover, a sterile swab immersed in the same incubated broth was further analyzed by a real-time PCR targeting GBS using the Xpert®GBS LB test on the GeneXpert® system (Cepheid). Results: Among the 288 antenatal screenings included in the study, 48 (16.7%) were positive for GBS using the culture reference method and 51 Xpert®GBS LB test were positive (17.7%), includin the 48 samples positive in culture and 3 additional specimens for witch culture remained negative. Considering the enriched culture as the gold standard, the sensitivity and specificity of the Xpert®GBS LB test were 100% and 98.8% respectively. Conclusions: The Xpert®GBS LB test performed on incubated LIM broth is at least as efficient as selective enriched culture for antenatal screening of GBS. The turnaround-time and hands-on-ti are much shorter for the Xpert® GBS LB but it is more expensive than culture method, which may limit its use. [less ▲]

The diametral dimension is a topological invariant which characterizes Schwartz and nuclear spaces. However, there exists another diametral dimension which was conjectured by Bessaga, Mityagin, Pełczynski, and Rolewicz to be equal to the first one in Fréchet spaces. In this talk, we describe some conditions which assure the equality of the two diametral dimensions in metrizable locally convex spaces. Besides, we explain why such an equality is generally impossible in non-metrizable spaces. [less ▲]
