Successful embryo development requires an extensive endometrial angiogenesis in proximity of implantation site. The glycoprotein hCG is produced even before implantation by trophoblast in normal pregnancy. In this manuscript, we demonstrate an angiogenic effect of hCG in several in vivo (chick chorioallantoic membrane, matrigel plug assay, aortic ring assay) and in vitro experimental models. In contrast, human placental lactogen (hPL) did not display angiogenic properties. LH/hCG receptor was detected in endothelial cells by reverse-transcriptase polymerase chain reaction (RT-PCR) and by Western blotting. In mice aortic ring assay, angiostimulation by hCG was abrogated by deletion of LH/hCG receptor (LuRKO mice). Use of recombinant hCG and anti-hCG antibody (Ab) further confirmed the specificity of this angiogenic activity. By using dibutyryl cAMP, adenylate cyclase, or protein kinase A inhibitors, we demonstrate that hCG-mediated angiogenesis involves adenylyl-cyclase-protein kinase A activation. Addition of hCG to endometrial epithelial epithelial cells, but not to cultured endothelial cells, stimulated vascular endothelial growth factor (VEGF). VEGF and hCG also displayed additive activities. Altogether, these data demonstrate that peritrophoblastic angiostimulation may result from a paracrine dialogue between trophoblast, epithelial, and endothelial cells through hCG and VEGF. [less ▲]

This deliverable summarises all the hydrogeological experiments performed in the scope of the AquaTerra project by HGULg in the Flémalle test site. These experiments consisted in various hydraulic tests and tracer tests performed to quantify hydrodynamic and hydrodispersive properties of the alluvial gravel aquifer and to evaluate groundwater fluxes in the aquifer and at the aquifer-river interface. First steps in groundwater modelling are also presented. [less ▲]

An empirical model called NeQuick has been selected for the modelling and correction of the ionospheric delay contribution in GALILEO single frequency receivers. The current baseline version of NeQuick for GALILEO is the one available in the International Telecommunication Union – Radiocommunication Sector (ITU-R) since 2001. From that time, several improvements have been proposed leading to the need of a better understanding and comparison of these different versions and an analysis of the weaknesses. Better results have been obtained by means of simpler ionosonde and profile parameters calculations, different topside formulation and new data files. The interest of a newer version of NeQuick including the above-mentioned modifications is highlighted as its error behaviour towards latitude shows a better agreement with reality. Those modifications should be coupled to a less simplistic topside formulation involving several layers with appropriate transitions such as the proposal introduced in this paper. The need of a different treatment regarding the daily effective use of the model for GALILEO single frequency algorithm compared to a physical use (that uses monthly median underlying data) is addressed. For the analysis and comparison of the different variants of the model, a software tool with a Graphical User Interface was developed. Preliminary comparisons for the physical use between different versions and also between modelled and measured data are presented. Such comparisons should be extended in the future for the effective use of the model. Finally, the structure and analysis of the mentioned issues and the results of the different comparisons are shown. Also solutions or potential paths to investigate solutions are proposed. [less ▲]

We study the the design of a tracking controller for the popular bouncing ball model: the continuous-time actuation of a table is used to control the impacts of the table with a bouncing ball. The proposed control law uses the impact times as the sole feedback information. We show that the acceleration of the table at impact plays no role in the stability analysis but is an important parameter for the robustness of the feedback system to model uncertainty, in particular to the uncertainty on the coefficient of restitution.

Astrocytic tumours are associated with dismal prognoses due to their pronounced ability to diffusely invade the brain parenchyma. Various neuropeptides, including gastrin, are able to modulate tumour astrocyte migration. While neurotensin has been shown to influence the proliferation of glioma cells and the migratory ability of a large set of other cell types, its role in glioma cell migration has never been investigated. Neurotensin-induced modifications to the motility features of human U373 glioblastoma cells therefore constitute the topic of the present study. We evidenced that three subtypes of neurotensin receptors (NTR1, NTR2 and NTR3) are expressed in U373 glioblastoma cells, at least as far as their mRNAs are concerned. Treating U373 tumour cells with 10 nM neurotensin markedly modified the morphological patterns of these cells and also profoundly altered the organization of their actin cytoskeletons. Pull-down assays revealed that neurotensin induced the activation in U373 cells of both Rac1 and Cdc42 but not RhoA. Scratch wound assays evidenced that neurotensin (0.1 and 10 nM) very significantly inhibited wound colonization by U373 cells cultured in the absence of serum. In addition, quantitative phase-contrast videomicroscopy analyses showed that neurotensin decreases the motility levels of U373 glioblastoma cells when these cells are cultured on plastic. In sharp contrast, neurotensin stimulates the motility of U373 cells when they are cultured on laminin, which is a pro-adhesive extracellular matrix component ubiquitously secreted by glioma cells. Our data thus strongly suggest that, in addition to gastrin, neurotensin is a neuropeptide capable of modulating tumour astrocyte migration into the brain parenchyma. [less ▲]

Described in 1960 by Jean Delay in relation to the use of haloperidol, neuroleptic malignant syndrome remains relatively rare, and poorly known by the medical profession. The emergence of the atypical antipsychotic agents and preventive measures which have become general in recent years in hospital departments using dopamine receptor antagonists has not altered the prognosis, which remains potentially fatal in approximately a quarter of cases. This article proposes a descriptive summary of this syndrome in terms of clinical and biological diagnostics as well as of evolution, epidemiology, differential diagnosis and treatment. It describes the case of a patient affected by general paralysis having developed a neuroleptic malignant syndrome, thus the hypothesis what the neuroleptic malignant syndrome preferentially arises in subjects having underlying organic or metabolic problems and provides food for thought regarding the main medical and psychiatric overlaps, the use of dopaminergic agents and the behaviour to be adopted when dealing with a patient presenting with inaugural psychiatric symptomatology.
