Cystic lymphangioma of the mesentery is a benign condition, probably of malformative origin, and frequently appearing in infancy. Its symptomatology can be very polymorphic. Its diagnosis is suspected by ultrasonography and computed tomography, and definitely confirmed by pathology. About a recent case of cystic lymphangioma of the mesentery diagnosed and operated on at the university hospital of Liege in an adult patient, the authors review its classification and its therapeutic strategy. Surgical resection is indicated in symptomatic cystic lymphangioma. [less ▲]

Induced by climate change, intensity and frequency of droughts should be more important for the next century. How does water availability affect the physiology of woody plants at the species and stand scale? Carbon and water vapour fluxes measurements of a mixed forest (deciduous and coniferous) were performed for over ten years by the eddy covariance method in Belgian Ardennes (Aubinet et al, 2001) as a part of the CarboEurope project. Whereas carbon fluxes have been analyzed in detailed and good estimations of the Net Ecosystem Exchange (NEE) and Gross Primary Production (GPP) were obtained, a thorough analysis of water vapour fluxes remains to be done. Improving analysis of water vapour fluxes and monitoring species transpiration will contribute to the estimation of the water use efficiency, WUE, at both the species and stand scale. The WUE well characterizes the vegetation productivity and ecosystem response to environmental factors. It also allows evaluating the sensitivity of temperate woody species to drought. The species concerned are beech (Fagus sylvatica L.), Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) and silver fir (Abies alba Mill.). Since summer 2009 we monitor and analyze each species water use by measuring sap flow with the thermal dissipation method (Granier, 1987). Results at the species level will then be upscaled and compared to stand water vapour fluxes measurements obtained by the eddy covariance methodology. Transpiration of each species will be analyzed in relation with their own phenological and ecophysiological attributes, ecosystem soil and atmospheric conditions, to clarify among others their behaviour in case of water deficit. Data are actually analysed, the presented results will concern the 2009, and a part of 2010 growing season. [less ▲]

This study is interested in the theoretical and actual functioning of the emissions trading systems resulting from the coming into force of the Kyoto protocol in 2005 and the implementation of the European Union Emissions Trading Scheme (EU ETS) in 2002. The first part of the work is devoted to a literature-based analysis of the Kyoto flexible mechanisms: Emissions Trading (ET), Clean Development Mechanism (CDM) and Joint Implementation (JI). These mechanisms allow the protocol's parties to achieve their objectives at the lowest cost, using a "cap and trade" strategy. Concerning ET, the issues of the surplus of emissions rights (called "hot air") and the effects of the economic crisis are tackled. An analysis of the spatial and sectoral distribution of CDM and JI is also conducted. The second part concerns the EU ETS, the coordinated emissions trading system of the European Union. With this system, companies with a high level of emissions established in at least one of the member countries directly support a part of the global constraint resulting from the involvement of the EU in the Kyoto protocol. The system also use a "cap and trade" strategy and has been progressively spatially and sectorally extended. As for Kyoto flexible mechanisms, an analysis of the structure and the functioning of this market is done on the basis of the literature. In addition, the implementation of this system within the firms is described through actual business cases and is compared with theoretical observations. In particular, we focus on emissions monitoring and portfolio optimization. In the third part of the work, we conduct and in-depth qualitative analysis of the impact of EU ETS on the competititveness of firms subject to the constraint in Belgium. Interviews has been done with heads of four companies selected for their differences in terms of size, emissions level, sector and environmental policy. The answers collected are systematically compared with the multinational survey of the independent specialized consultant PointCarbon (2010). Results show that opinions about the impact on the competitiveness are strongly influenced by sector and size of the firms. [less ▲]

Ischaemic mitral regurgitation is a frequent complication of left ventricular global or regional pathological remodelling due to chronic coronary artery disease. It is not a valve disease but represents the valvular consequences of increased tethering forces (papillary muscles displacement leading to a more apical position of the leaflets and their coaptation point) and reduced closing forces (reduced contractility, dyssynchrony of the papillary muscles, intra-left ventricular dyssynchrony). Although mitral regurgitation has an unloading effect and reduces impedance, the volume overload begets further left ventricular dilatation, increases ventricular wall stress leading to worsened performance. Ischaemic mitral regurgitation is characteristically dynamic: its severity may vary with haemodynamic conditions. Both the severity of ischaemic mitral regurgitation and its dynamic component worsen prognosis. There are numerous possible treatment modalities, but the management of the individual patient remains difficult. Medical therapy is mandatory; revascularization procedures are frequently not sufficient to reduce mitral regurgitation; the role of combined surgical therapy by mitral valve repair is not yet defined in the absence of large randomized trial. Some patients are good candidates for cardiac resynchronization therapy that may reduce the amount of regurgitation. New therapeutic targets are under investigation. [less ▲]

Due to growing interests in environmental and building energy performance concerns, building physics simulations - and especially Computational Fluid Dynamics (CFD) – are more and more used. Unfortunately, until now, there is no clearly defined method to validate the use of these models by building engineers. This paper describes a validation process of CFD tools dealing with physical phenomena occurring in building physics. The comparison between experimental data and numerical results proves the validity of CFD use and its specific contribution to building physics modelling in comparison with thermal multizonal models. Thanks to this validation process, building engineers can improve their CFD simulations performance and their comprehension of building physics. [less ▲]

This article replaces the restoration of a Madonna and Child by Joseph Van der Vecken within the context of a period.Documented by the patron, the intervention did not meet his expectations and resulted in a de-restoration. This fact, far from being anecdotic, is proof of the change in mentalities and sensitivities in the first half of the twentieth century and of the emergence of a new concept of restoration [less ▲]

ABSTRACT: BACKGROUND: Doublecortin (Dcx), a MAP (Microtubule-Associated Protein), is transiently expressed in migrating and differentiating neurons and thereby characterizes neuronal precursors and neurogenesis in developing and adult neurogenesis. In addition, reduced Dcx expression during development has been related to appearance of brain pathologies. Here, we attempt to unveil the molecular mechanisms controlling Dcx gene expression by studying its transcriptional regulation during neuronal differentiation. RESULTS: To determine and analyze important regulatory sequences of the Dcx promoter, we studied a putative regulatory region upstream from the mouse Dcx coding region (pdcx2kb) and several deletions thereof. These different fragments were used in vitro and in vivo to drive reporter gene expression. We demonstrated, using transient expression experiments, that pdcx2kb is sufficient to control specific reporter gene expression in cerebellar cells and in the developing (E14.5) brain. We determined the temporal profile of Dcx promoter activity during neuronal differentiation of mouse embryonic stem cells (mESC) and found that transcriptional activation of the Dcx gene varies along with neuronal differentiation of mESC. Deletion experiments and sequence comparison of Dcx promoters across rodents, human and chicken revealed the importance of a highly conserved sequence in the proximal region of the promoter required for specific and strong expression in neuronal precursors and young neuronal cells. Further analyses revealed the presence in this short sequence of several conserved, putative transcription factor binding sites: LEF/TCF (Lymphoid Enhancer Factor/T-Cell Factor) which are effectors of the canonical Wnt pathway; HNF6/OC2 (Hepatocyte Nuclear Factor-6/Oncecut-2) members of the ONECUT family; and NF-Y/CAAT (Nuclear Factor-Y). CONCLUSIONS: Studies of Dcx gene regulatory sequences using native, deleted and mutated constructs suggest that fragments located upstream of the Dcx coding sequence are sufficient to induce specific Dcx expression in vitro: in heterogeneous differentiated neurons from mESC, in primary mouse cerebellar neurons (PND3) and in organotypic slices cultures. Furthermore, a region in the 3'-end region of the Dcx promoter is highly conserved across several species and exerts positive control on Dcx transcriptional activation. Together, these results indicate that the proximal 3'-end region of the mouse Dcx regulatory sequence is essential for Dcx gene expression during differentiation of neuronal precursors. [less ▲]
