Variceal bleeding is frequently the initial presentation of a previously unknown cirrhosis. Portal hypertension and its complications without liver cirrhosis should raise the possibility of presinusoidal portal hypertension, and the diagnosis of hepatoportal sclerosis. These patients need to be investigated for coagulation disorders. A hypercoagulable state is often associated. Risks and benefits of anticoagulation should be further investigated in these patients.

The Auteur research geoindicators indicating the presence of a Roman road. A geo-indicator is a localised item that accompanies other item less apprehensible. Eight indicators are discussed (straightness, elevated road, position on the ridge, administrative border, chapel, parcelling, other roman traces, toponym). These geoindicators permit searching Roman road but also determine the more characteristic sectors. [less ▲]

The knowledge of distribution and ecological determinants of species is a prerequisite to their conservation at a time where declines are generalized at a world scale. The aim of this study is to characterize these topics to discuss the status of amphibian species in Pays de Herve, an area which is representative of hedged farmland regions and their evolution toward a landscape homogenization. On more than four hundreds ponds surveyed, 72% contained amphibians. All Walloon amphibian species (except those recently disappeared), were present but some were rare. The natterjack toad and the crested newt are the two most threatened species in a close future, but almost all species are threatened with large population decreases. The destruction and abandon of cattle ponds is the primary factor of decline of amphibians in Pays de Herve, but other factors such as fish introduction and water pollution have also a negative impact in decreasing biodiversity in favour of less specialized species. Management and conservation measures should be taken as soon as possible to stop or at least slow down the current process. [less ▲]

Le cancer du sein représente chez la personne âgée une pathologie fréquente. Le choix du traitement dépend de l'âge physiologique, des pathologies et comorbidités associées ainsi que du niveau de vie et d'autonomie. De plus, selon les facteurs histopronostiques (récepteurs aux oestrogènes et à la progestérone, la surexpression du cerb-B2) on décidera éventuellement du schéma thérapeutique le plus approprié. Chez la personne âgée, la chirurgie (mastectomie ou tumorectomie), la radiothérapie et l'hormonothérapie trouvent leur place. Au-delà de 70 ans, la place de la chimiothérapie est incertaine. En effet, les patientes de plus de 70 ans sont sous-représentées dans les études randomisées. [less ▲]

Cet article tente de démontrer l’émergence de nouvelles politiques sociales concernant les personnes handicapées en Belgique. Nous nous attarderons sur des pratiques spécifiques appelées « accompagnement de personnes handicapées ». Il vise principalement à démontrer la présence de trois modèles de politiques du handicap. Ces trois modèles sont : le « modèle aliéniste », le « modèle protectionnel » et le « modèle de l’activation ». Nous expliquerons pourquoi le modèle de l’activation est important pour comprendre la redéfinition des politiques sociales de nos jours. [less ▲]

In the crystal structure of the reduced form of the wild-type human peroxiredoxin 5, the presence of a benzoate ion in direct interaction with the peroxidatic cysteine (Cys 47) appeared as a rather intriguing feature since it is known that the benzoate ion can play the role of a specific hydroxyl radical scavenger. The crystal structure of the C47S mutant of the same enzyme has been crystallized in the tetragonal system, space group P41212, with a = 65.65 Å, c = 122.04 Å. It confirms the presence of this benzoate ion in spite of the mutation into a serine of the Cys 47 residue to which the benzoate ion was directly linked in the wild-type structure. The benzoate ion seems to be stabilized by hydrophobic contacts on both sides of the aromatic ring. In this matter, the α5 helix, which is specific to peroxiredoxin 5 among mammalian peroxiredoxins, plays an important role. These hydrophobic contacts also allow to suggest why the benzoate ion disappears when the molecule is oxidized. [less ▲]

Peroxiredoxin 5 is the last discovered mammalian member of an ubiquitous family of peroxidases widely distributed among prokaryotes and eukaryotes. Mammalian peroxiredoxin 5 has been recently classified as an atypical 2-Cys peroxiredoxin due to the presence of a conserved peroxidatic N-terminal cysteine (Cys47) and an unconserved resolving C-terminal cysteine residue (Cys151) forming an intramolecular disulfide intermediate in the oxidized enzyme. We have recently reported the crystal structure of human peroxiredoxin 5 in its reduced form. Here, a new crystal form of human peroxiredoxin 5 is described at 2.0 Ǻ resolution. The asymmetric unit contains three polypeptide chains. Surprisingly, beside two reduced chains, the third one is oxidized although the enzyme was crystallized under initial reducing conditions in presence of 1 mM 1,4-dithio-DL-threitol. The oxidized polypeptide chain forms an homodimer with a symmetry related one through intermolecular disulfide bonds between Cys47 and Cys151. The formation of these disulfide bonds is accompanied by the partial unwinding of the N-terminal parts of the a2 helix, which in the reduced form, contains the peroxidatic Cys47 and the α6 helix, which is sequentially close to the resolving residue Cys151. In each monomer of the oxidized chain, the C-terminal part including the α6 helix is completely reorganized and is isolated from the rest of the protein on an extended arm. In the oxidized dimer, the arm belonging to the first monomer now appears at the surface of the second subunit and vice versa. [less ▲]

Near a small city of the Belgian ‘Ardennes’ (East of Belgium), modification of a natural slope for extension of industrial activities has required an extensive drainage in a weathered zone composed of colluvium and weathered claystones and quartzites. After a few days, the drain at the foot of the artificial slope was producing about 1000 m3/day while a natural spring located at a 200 m distance on the hillside was completely dried up. This spring was used for drinking water by the local community. A shallow geophysical prospection by refraction seismics and 2D geoelectrical tomography, associated to geological, morphostructural and hydrogeological observations have lead to a clear understanding of (1) the spring occurrence; (2) the feeding conditions of the spring and consequently (3) the ‘lateral’ hydraulic impact of the drain. In the hill, the bedrock is changing from quartzites (uphill) to claystones (downhill) inducing changes in hydraulic conductivity and thickness of the overlying weathered zone. On the basis of these hydrogeological conditions, associated to the specific topographic conditions, different possible remediation schemas have been proposed to the decision makers. Unfortunately, the full restoration of the natural spring appears to be one of the most technically and financially difficult option …while it is surely the most suitable in the name of a sustainable development.

The effect of repeated exposure to specific chemicals on the initiation or progression of mycosis fungoides (MF) remains unsettled. A patient with low-grade patch stage MF progressively developed MF plaques restricted to his arms, and a tumour on his right thigh. These areas were subject to repeated exposure to solvents. His thigh was indeed in close contact with his trousers pocket where he used to store a wiping rag drenched into white spirit and cellulosic thinner. Immunophenotyping these lesions revealed a dense LCA+, CD2+, CD3+, CD4+, CD5+, CD7+, CD45+, CD45RO+ T-cell infiltrate admixed with many factor XIIIa+ dendrocytes. T-cell receptor rearrangement analysis identified a monoclonal T-cell infiltrate. An internal work-up remained negative. Stopping further solvent exposure failed to improve his condition. Oral corticotherapy combined with low-dose interferon-alpha2a halted disease progression. This observation suggests that long-term solvent exposure may trigger MF and hasten its progression from the patch stage to the plaque and tumour stages. Copyright (C) 2004 S. Karger AG, Basel.
