The thyrogastric autoimmune syndrome (TAS) was described in patients in whom the serum cross-reacted both with gastric parietal cells antigens and thyroid antigens. We describe several cases illustrating the spectrum of pathogical features of TAS. Autoimmune thyroiditis include Hahimoto’s Thyroiditis and Graves Disease. Autoimmune gastritis may present at first only micronutrients deficiency (B12, iron) whereas Biermer anemia with gastric atrophy and gastrin cell hyperplasia is the consequence of long standing disease. One possible presentation of gastric autoimmunity is the association with Helicobacter pylori infection. Gastric autoimmunity is potentially reversible if Helicobacter is erradicated. When gastric autoimmunity is irreversible, this condition leads to gastric severe atrophy, hypochlorhydria and hypergastrinemia. Hypergastrinemia stimulates enterochromaffin cell hyperplasia, progressing eventually to neuroendocrine tumors. The thyrogastric syndrome should be considered a risk factor to develop a neuuroendocrine tumor. We propose a diagnostic approach to improve the characterization of TAS. We review the literature on the subject and discuss some interesting animal models of infectious gastric autoimmunity [less ▲]

Models are the only tools capable of predicting the evolution of groundwater systems at a regional scale in taking into account a large amount of information. This study presents the association of a water balance model (WetSpass) with a groundwater flow and solute transport model (SUFT3D, « Saturated and Unsaturated Flow and Transport in 3D ») in order to simulate the present and future groundwater quality in terms of nitrate in the Upper Dyle basin (439 km², Belgium). The HFEMC (« Hybrid Finite Element Mixing Cell ») method implemented in the SUFT3D code is used to model groundwater flow and nitrate transport. A spatially-distributed recharge modelled with WetSpass is considered for prescribing the recharge to the groundwater flow model. The feasibility of linking WetSpass model with the finite-elements SUFT3D code is demonstrated. Time evolution and distribution of nitrate concentration are then simulated using the calibrated model. Nitrate inputs are spatially-distributed according to land use. The spatial simulations and temporal trends are compared with previously published data on this aquifer and show good results.

The guidance of human sperm cells under con finement in quasi 2D microchambers is investigated using a purely physical method to control their distribution. Transport property measurements and simulations are performed with diluted sperm populations, for which eff ects of geometrical guidance and concentration are studied in detail. In particular, a trapping transition at convex angular wall features is identi ed and analyzed. We also show that highly efficient microratchets can be fabricated by using curved asymmetric obstacles to take advantage of the spermatozoa specifi c swimming strategy. [less ▲]

If we easily categorize sung performances as “in tune” or “out of tune”, it is not so evident to explicitly describe on which criteria our evaluation is based. This presentation reports recent work on pitch accuracy perception in a melodic context. The results allow to refine the notion of pitch accuracy and therefore to design objective tools for the evaluation of singer quality. [less ▲]

Aim Transcatheter aortic valve implantation has become an alternative to surgery in higher risk patients with symptomatic aortic stenosis. The aim of the ADVANCE study was to evaluate outcomes following implantation of a self-expanding transcatheter aortic valve system in a fully monitored, multi-centre ‘real-world’ patient population in highly experienced centres. Methods and results Patients with severe aortic stenosis at a higher surgical risk inwhomimplantation of theCoreValve Systemwas decided by the Heart Teamwere included. Endpointswere a composite of major adverse cardiovascular and cerebrovascular events (MACCE; all-cause mortality, myocardial infarction, stroke, or reintervention) and mortality at 30 days and 1 year. Endpoint- related eventswere independently adjudicated based on Valve AcademicResearch Consortiumdefinitions.Atotal of 1015 patients [mean logistic EuroSCORE 19.4+12.3% [median (Q1,Q3), 16.0% (10.3, 25.3%)], age 81+6 years] were enrolled. Implantation of the CoreValve System led to a significant improvement in haemodynamics and an increase in the effective aortic valve orifice area. At 30 days, theMACCErate was 8.0% (95% CI: 6.3–9.7%), all-cause mortalitywas 4.5% (3.2–5.8%), cardiovascular mortality was 3.4% (2.3–4.6%), and the rate of stroke was 3.0% (2.0–4.1%). The lifethreatening or disabling bleeding rate was 4.0% (2.8–6.3%). The 12-month rates of MACCE, all-cause mortality, cardiovascular mortality, and stroke were 21.2% (18.4–24.1%), 17.9% (15.2–20.5%), 11.7% (9.4–14.1%), and 4.5% (2.9–6.1%), respectively. The 12-month rates of all-cause mortality were 11.1, 16.5, and 23.6% among patients with a logistic Euro- SCORE ≤10%, EuroSCORE 10–20%, and EuroSCORE .20% (P , 0.05), respectively. Conclusion The ADVANCE study demonstrates the safety and effectiveness of the CoreValve System with low mortality and stroke rates in higher risk real-world patients with severe aortic stenosis.

In België bestaat er een nauwe band tussen talen (Nederlands-Frans) en regionale identiteiten (Vlaming-Waal). Echter, de aanwezigheid van Franstaligen in Vlaanderen en van Nederlandstaligen in Wallonië laat zien dat deze band niet automatisch is. Deze twee (onder)bevolkingsgroepen lijken dus een ideaal studiemateriaal om de ingewikkelde relatie tussen taal (talen) en identiteit(en) te bestuderen. Ondanks de belangstelling van verschillende disciplines (onder meer politieke wetenschappen, geschiedenis, sociologie en taalkunde) voor dit onderwerp, valt het toch op dat deze bevolkingsgroepen nog nooit onderzocht werden. In dit onderzoeksproject willen we daarom aan de hand van biografische gesprekken nagaan (i) hoe deze minoriteitsgroepen in een anderstalige context hun identiteit opbouwen, en (ii) in hoeverre ze identiteitsstrategieën gebruiken naargelang van de communicatiecontext waarin ze zich bevinden. Om deze vragen te beantwoorden, zullen biografische gesprekken verzameld worden die die vanuit het interdisciplinaire perspectief van de sociologie, de sociale psychologie, de sociolinguïstiek en de taalkunde geanalyseerd zullen worden. In deze bijdrage zullen we specifieker ingaan op de methodologie die wij zullen gebruiken om deze biografische gesprekken te analyseren. We zullen meer bepaald uitgaan van een tweeledige analyse van identiteitsmarkeerders. Ten eerste zullen we een semantische studie van de identiteitscategorieën verrichten, door de lexicale eenheden te bestuderen die door de informanten gebruikt worden om hun identiteit te omschrijven. Het is hiermee de bedoeling om de sociale categorieën die de respondenten gebruiken verder in kaart te brengen. Ten tweede zullen wij een psychosociale studie van de identiteitsstrategieën van de informanten verrichten. Vanuit dit perspectief kan een identiteit beschouwd worden als het resultaat van de interactie tussen een “identiteit voor zichzelf” en een “identiteit voor de anderen”. In dit onderdeel van onze studie willen we de persoonlijke identiteitsstrategieën van de informanten aan het licht brengen onder meer door hun identiteitskeuzes, zoals bijvoorbeeld de keuze voor een taalvariëteit in een bepaalde communicatiecontext, nauwkeurig te bestuderen. Deze tweedelige methode zal het mogelijk maken om de relatie tussen taal en identiteit in België beter te begrijpen en nauwkeuriger te kunnen omschrijven. [less ▲]

The Ground Penetrating Radar (GPR) is a non-destructive method used for roads and buildings inspection: it is well adapted to detect the different layers constituting the structures. The objective of this thesis is to develop a method for a fast determination of the properties of a buried layer on the basis of surface GPR measurements. The observation of the GPR waves propagation in numerical simulations led to develop an analytical model, which could be applied to the experimental determination of laboratory layered structures.
