Abstract A l'extrême fin du 19e siècle, l'Art nouveau s’épanouit sous des formes diversifiées, parfois contradictoires, mais partageant généralement la même volonté de rompre avec l'académisme et l'historicisme du siècle finissant. Parmi les acteurs de cet Art nouveau, certains ne retiennent que le côté décoratif d’une nouvelle esthétique. Très tôt cependant, au cœur même de ce mouvement d’avant-garde, apparaissent les prémices du renouvellement qui le condamnera et conduira au Modernisme. Quelques travaux de Gustave Serrurier – mobilier ou architecture – méritent d’être observés sous cet angle. [less ▲]

« Il ne faut pas travailler pour un monde qui disparaît mais pour un monde nouveau dont on peut prévoir l’avènement ». Architecte par vocation et formation, puis commerçant, ensuite créateur et industriel, le Liégeois Gustave Serrurier (1858-1910) est rapidement convaincu de la nécessité de lier l’architecture aux arts décoratifs. Il le fait avec la conviction politique et esthétique qu’une production industrialisée permettra de donner au plus grand nombre l’environnement artistique auquel tout être peut prétendre. Il pressent que le temps de l’artisanat est en passe d’être révolu et équipe progressivement ses ateliers de machines modernes. Si ses premières créations restent empreintes de l’esprit constructif des artisans néogothiques, s’il emploie ensuite des jeux de lignes courbes, tendues et maîtrisées, le début du XXe siècle le voit évoluer vers toujours plus de simplicité constructive et plus de rigueur géométrique. Grâce au mobilier, aux objets et aux aménagements d’intérieurs qu’il crée et fait réaliser par la centaine d’ouvriers de ses ateliers liégeois, sa firme prend rapidement une ampleur internationale et se fait remarquer dans les expositions universelles comme celle de Saint-Louis (U.S.A.) en 1904. Anticipant sur ce que seront les motivations d’un Bauhaus, ses préoccupations sociales et esthétiques conduisent Serrurier à imaginer un mobilier de plus en plus économique, rationnellement construit, adapté à l’usage et au lieu de destination, par exemple pour une habitation ouvrière à l’Exposition universelle de Liège en 1905. Là, un mobilier en orme équipe la salle commune égayée d’une frise au pochoir et de rideaux de lin garnis de carrés colorés. On y remarque un meuble à usage multiple, tout à la fois armoire, secrétaire et bibliothèque, sans autre décor que sa composition équilibrée ; banc, table et chaises sont faits d’éléments assemblés par des vis apparentes. C’est à cette même époque que Serrurier développe la ligne “Silex”, particulièrement représentative ; conçue de façon tout à fait originale et pragmatique, exécutée en bois blanc et décorée au pochoir, la plupart des assemblages de menuiserie sont remplacés par des vis apparentes. La découpe des planches se montre économe en matière. Une chaise, objet d’utilité commune, se doit d’être robuste, ergonomique et peu coûteuse à produire : ici, la production en série est aisée et pourra être assurée dans ses ateliers équipés de scies mécaniques et autres machines-outils. A l’examen, une chaise de cette série exprime bien les qualités de designer industriel de son concepteur et le place à l’avant-garde de son temps ; elle illustre aussi ses ambitions, tant sociales qu’esthétiques, et sa volonté d’un « art pour tous ».

BACKGROUND: Addition of glutamine to enteral nutrition formulas is consistently associated with a significant decrease in septic morbidity in critically ill patients, possibly related to the attenuation of gut dysfunction. This pilot study was undertaken to compare the effects of enteral administration of two glutamine-enriched formulas containing either additional free glutamine or glutamine-rich proteins, with a standard solution on plasma and mucosal concentrations of glutamine in patients admitted in the Department of Intensive Care. METHODS: Following randomization, glutamine concentration was determined in endoscopically sampled duodenal biopsies and plasma, before and after a 7-day period of continuous administration of the designated solution. RESULTS: The mucosal concentration of glutamine increased in the duodenal biopsies sampled from patients randomized to the solution containing the glutamine-rich proteins (from 3.6 +/- 2.2 to 6.7 +/- 5.2 micro-mol/g protein), but not from the others. There were no differences between the 3 groups in the plasma concentrations of glutamine, which remained stable over time. CONCLUSION: The source of supplemental glutamine can influence gut mucosal glutamine concentrations, suggesting differences in its availability or utilization. [less ▲]

It was demonstrated in 1981 that chronic GVHD was associated with a strong decrease of the relapse risk after conventional allogeneic hematopoietic cell transplantation (graf-versus-tumor effects). Recent studies suggest that chronic GVHD might also been associated with improved progression-gree survival after allogeneic hematopoietic cell transplantation with reduced-intensity conditioning (RIC-allo), a transplant strategy based mainly on graft-versus-tumor effects for tumor eradication. Further, it has been demonstrated that elimination of leukemic cells after RIC-allo is due to donor T-cell cloones directed against multiple minor histocompatibility antigens (specific for the recipient) that are largely expressed not only by tumor cells but also by non-hematopoietic tissues, explaining the strong association between GVHD and graft-versus-tumor effects seen after RIC-allo.

Background: The Ehlers-Danlos syndrome (EDS) represents a heterogenous group of heritable connective tissue disorders chiefly characterized by joint laxity, increased skin distensibility and connective tissue fragility. Each EDS type corresponds to a multisystemic disorder with widespread implications. Physicians evoke the EDS diagnosis in presence of some typical cutaneous signs, such as atrophic scars and frequent hematomas. Methods: To revisit the transmission electron microscopy support from skin biopsies when screening EDS in gynecology-obstetrics. Results: EDS women commonly suffer from a series of gynecologic and obstetric disorders. Dermal ultrastructural changes are keynote features suggesting some EDS types. Conclusion: Gene mutations are mostly identified in the classic and vascular EDS types, but only in sporadic cases of the hypermobile EDS type which apparently represents the most frequent type. Dermal ultrastructural changes represent relevant diagnostic clues for the practitioner. Preconception counseling about possible complications is welcome. Management requires precise diagnosis of the EDS type. [less ▲]

In the present study, we used meiotic gynogenesis, widely used in studies on sex determination, to confirm female homogamety in Eurasian perch, Perca fluviatilis. Sperm irradiated with UV for 400 s was used to artificially fertilized eggs. The diploid of the resulting embryos was restored by a heat shock (30 degreesC) applied to the eggs 5 min postfertilization, for 25 min. Fertilization (ranging between 45% and 75%) and survival rates at hatching (ranging between 3.4% and 46.6%) were not significantly different (P>0.05) between the diploid control and gynogenetics. The diploid controls and two batches of gynogenetics contained 100% diploid larvae, whereas two other batches of gynogenetics contained 6.7% and 10.0% triploid larvae. The sex ratios of the diploid controls were not significantly different from 1:1, whereas all gynogenetic families were 100% female. These results confirm female homogamety in Eurasian perch, demonstrated by the use of hormonally mascilinized breeders in a previous study. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]

The histaminergic system has been speculated to be involved in the inhibitory control of drug reward, H-1 and H-2 antagonists having been found to potentiate conditioned place preference induced by morphine or cocaine. In contrast, the role of H-3 receptors in cocaine-induced place preference is still unknown. The present study tested the effects of thioperamide (0, 10 and 20 mg/kg, i.p.), an H-3 autoreceptor antagonist, on the development of a conditioned place preference induced by cocaine (0, 2 and 8 mg/kg, i.p.) in C57BL/6J mice. Thioperamide was injected 10 min before each cocaine-pairing session. The activity scores recorded on the first cocaine-pairing session were also used to test the effects of thioperamide on cocaine-induced locomotor activity. Thioperamide alone had no reinforcing effects and did not affect the conditioned place preference induced by 8 mg/kg cocaine. However, thioperamide dose-dependently revealed a conditioned place preference induced by 2 mg/kg cocaine, a dose that was inactive per se. Finally, thioperamide dose-dependently potentiated the stimulant effects of cocaine, in spite of its slight hypolocomotor effect when given alone. Our results strongly suggest that H3 antagonists potentiate the stimulant and reinforcing effects of cocaine in mice. © 2004 Elsevier B.V. All rights reserved. [less ▲]

Thin conductive magnetic shells are accounted for by means of two different time-domain magnetodynamic finite-element formulations, namely the magnetic field formulation and the magnetic vector potential formulation. Both approaches are an extension of the classical linear frequency-domain thin-shell approximation. The interface conditions for the magnetic field formulation and the vector potential formulation are expressed in terms of the average current density and the average flux density, respectively, together with a number of higher-order components of these quantities. The proposed time-domain thin-shell approaches are validated by means of a 3D magnetodynamic problem. The results are shown to agree well with those obtained with a fine model, whereas the computation time is significantly reduced. [less ▲]

Purpose - The aim of the present paper is to compare the performances of a finite-element perturbation technique applied either to the h- conform magnetodynamic formulation or to its b-conform counterpart in the frame of nondestructive eddy-current testing problems. Design/methodology/approach - In both complementary perturbation techniques, the computation is split into a computation without defect (unperturbed problem) and a computation of the field distorsion due to its presence (perturbation problem). The unperturbed problem is conventionally solved in the complete domain. The source of the perturbation problem is then determined by the projection of the unperturbed solution in a relatively small region surrounding the defect. The discretisation of this reduced domain is chosen independently of the dimensions of the excitation probe and the specimen under study and is thus well adapted to the size of the defect. Findings - The accuracy of the perturbation model is evidenced by comparing the results of the two counterpart formulations to those achieved in the conventional way for different dimensions of the reduced domain. The size of the reduced domain increases with the size of the defect at hand. This proposed sub-domain approach eases considerably the meshing process and speeds-up the computation for different probe positions. Originality/value - At a discrete level, the impedance change due to the defect is efficiently and accurately computed by integrating only over the defect itself and a layer of elements in the reduced domain that touches its boundary. Therefore, no integration of any flux variation in the coils is required. [less ▲]
