On confond trop souvent le mode de confection des gastrostomies avec le nom de l'équipement du conduit. Ainsi combien de fois avons-nous été appelés pour avis sur une « PEG » qui en fait était une gastrostomie équipée d'un bouton. Le but de ce travail est de clarifier les problèmes de techniques de gastrostomies chez l'enfant, les équipements à disposition et d'évoquer les problèmes qui s'y rapportent.

With the beginning of the European Monetary Union (EMU), euro-area sovereign securities¿ adjusted spreads over Germany (corrected from the foreign exchange risk) experienced an increase that caused a lower than expected decline in borrowing costs. The objective of this paper is to study what explains that rising. In particular, if it took place a change in the price assigned by markets to domestic (credit risk and/or market liquidity) or to international risk factors. The empirical evidence supports the idea that a change in the market value of liquidity occurred with the EMU. International and default risk play a smaller role

Plusieurs infirmières pratiquant dans les centres d'hébergement se questionnent sur la pertinence d'utiliser systématiquement certaines échelles de mesure. Elles sont d'avis que l'utilisation ou les modalités entourant l'usage de ces échelles augmentent surtout leur charge de travail et ne contribuent pas toujours à l'amélioration de la qualité des soins. Face à cette préoccupation, la communauté de pratique de la Faculté des sciences infirmières de l'Université Laval sur les soins à l'aîné en centre d'hébergement (CP-FSI) a voulu explorer les fondements à la base des recommandations de ces différents instruments de mesure en l'occurrence l'échelle du risque de plaie de pression de Braden et les échelles d'évaluation des risques de chute. Un examen de la littérature scientifique et l'analyse de données empiriques amènent à la conclusion que l'utilisation systématique de ces échelles alourdit en effet la tâche des infirmières. Qui plus est, le jugement clinique infirmier est équivalent ou supérieur à l'utilisation de ces échelles. La CP-FSI conclut à l'importance de modifier les recommandations sur l'usage systématique de ces échelles et de plutôt valoriser le jugement clinique des infirmières.

The corpus callosum (CC) is the major commissure that bridges the cerebral hemispheres. Agenesis of the CC is associated with human ciliopathies, but the origin of this default is unclear. Regulatory Factor X3 (RFX3) is a transcription factor involved in the control of ciliogenesis, and Rfx3-deficient mice show several hallmarks of ciliopathies including left-right asymmetry defects and hydrocephalus. Here we show that Rfx3-deficient mice suffer from CC agenesis associated with a marked disorganisation of guidepost neurons required for axon pathfinding across the midline. Using transplantation assays, we demonstrate that abnormalities of the mutant midline region are primarily responsible for the CC malformation. Conditional genetic inactivation shows that RFX3 is not required in guidepost cells for proper CC formation, but is required before E12.5 for proper patterning of the cortical septal boundary and hence accurate distribution of guidepost neurons at later stages. We observe focused but consistent ectopic expression of Fibroblast growth factor 8 (Fgf8) at the rostro commissural plate associated with a reduced ratio of GLIoma-associated oncogene family zinc finger 3 (GLI3) repressor to activator forms. We demonstrate on brain explant cultures that ectopic FGF8 reproduces the guidepost neuronal defects observed in Rfx3 mutants. This study unravels a crucial role of RFX3 during early brain development by indirectly regulating GLI3 activity, which leads to FGF8 upregulation and ultimately to disturbed distribution of guidepost neurons required for CC morphogenesis. Hence, the RFX3 mutant mouse model brings novel understandings of the mechanisms that underlie CC agenesis in ciliopathies.

S100A1 is a Ca(2+)-binding protein and predominantly expressed in the heart. We have generated a mouse line of S100A1 deficiency by gene trap mutagenesis to investigate the impact of S100A1 ablation on heart function. Electrocardiogram recordings revealed that after beta-adrenergic stimulation S100A1-deficient mice had prolonged QT, QTc and ST intervals and intraventricular conduction disturbances reminiscent of 2 : 1 bundle branch block. In order to identify genes affected by the loss of S100A1, we profiled the mutant and wild type cardiac transcriptomes by gene array analysis. The expression of several genes functioning to the electrical activity of the heart were found to be significantly altered. Although the default prediction would be that mRNA and protein levels are highly correlated, comprehensive immunoblot analyses of salient up- or down-regulated candidate genes of any cellular network revealed no significant changes on protein level. Taken together, we found that S100A1 deficiency results in cardiac repolarization delay and alternating ventricular conduction defects in response to sympathetic activation accompanied by a significantly different transcriptional regulation.

Taking as its point of departure recent insights about the performative¦nature of genre, The Poetics and Politics of the American Gothic¦challenges the critical tendency to accept at face value that gothic¦literature is mainly about fear. Instead, Agnieszka Soltysik Monnet¦argues that the American Gothic, and gothic literature in general,¦is also about judgment: how to judge and what happens when¦judgment is confronted with situations that defy its limits.¦Poe, Hawthorne, Melville, Gilman, and James all shared a concern¦with the political and ideological debates of their time, but tended¦to approach these debates indirectly. Thus, Monnet suggests, while¦slavery and race are not the explicit subject matter of antebellum¦works by Poe and Hawthorne, they nevertheless permeate it through¦suggestive analogies and tacit references. Similarly, Melville, Gilman,¦and James use the gothic to explore the categories of gender and¦sexuality that were being renegotiated during the latter half of the¦century. Focusing on The Fall of the House of Usher, The Marble¦Faun, Pierre, The Turn of the Screw, and The Yellow Wallpaper,¦Monnet brings to bear minor texts by the same authors that further¦enrich her innovative readings of these canonical works. At the same¦time, her study persuasively argues that the Gothic's endurance¦and ubiquity are in large part related to its being uniquely adapted¦to rehearse questions about judgment and justice that continue to¦fascinate and disturb.

This paper highlights the role of non-functional information when reusing from a component library. We describe a method for selecting appropriate implementations of Ada packages taking non-functional constraints into account; these constraints model the context of reuse. Constraints take the form of queries using an interface description language called NoFun, which is also used to state non-functional information in Ada packages; query results are trees of implementations, following the import relationships between components. We define two different situations when reusing components, depending whether we take the library being searched as closed or extendible. The resulting tree of implementations can be manipulated by the user to solve ambiguities, to state default behaviours, and by the like. As part of the proposal, we face the problem of computing from code the non-functional information that determines the selection process.

In this paper I show that employees tend to procrastinate when they are expected to decide whether or not they would like to save using the defined contribution pension scheme offered by their employer. By auto-enrolling the employees or asking them to decide before a given deadline, employers can mitigate some of the problems caused by employee procrastination. However both of these mechanisms present their own problems, caused by default stickiness and other issues, so I discuss how employers can decide which is the right mechanism to use depending on the characteristics of their employees, and how to minimize the problems these mechanisms can cause.

We find that the vast majority of students taking an advanced undergraduate finance course show a preference for luck in a classroom experiment. In Phase I of the experiment part of the students, group A, were asked to guess a coin toss five times in a row. In Phase II the rest of the students, group B, were given 10 EUR to bet on some of the Group A students taking a second go at guessing a sequence of five coin tosses (Phase III). Group B students’ bets were by default allocated to the worse performing student in Phase I. Switching to better performing Group A students was costly. A total of 23 out of 28 students were willing to pay for switching and thus showed a preference for luck.

We provide evidence that Formica paralugubris Seifert, 1996, a species of wood and recently described from Switzerland, is present in the Italian Alps. Until 1996, this species was confounded with F.lugubris Zetterstedt, 1838. We examine the wood and collection deposited at the University of Pavia (Italy) and collect new samples within the Italian Alps. Formica paralugubris seems to be more abundant than F.lugubris. Moreover, both species are found in sympatry in some localities

The objective of this work was to determine the combining ability and heterosis, for productivity and yield components, in diallel hybrids derived from crossings between BRSMG-Talismã, IPR Uirapuru, FT Soberano, BRS Campeiro, IAC Tybatã, and IPR Juriti parent cultivars. Fifteen hybrids were generated from diallel crosses, excluding reciprocals. The general and specific combining abilities were significant for plant height, number of pods per plant, number of seeds per plant, number of seeds per pod, 50-seed weight, and grain yield, indicating the occurrence of both additive and nonadditive genetic effects. The best strategy to be adopted is the use of BRS Campeiro, FT Soberano and BRSMG-Talismã cultivars in common bean breeding programs involving selection. The most promising combinations were 'IPR Uirapuru' x 'IAC Tybatã', 'IPR Uirapuru' x 'FT Soberano', 'BRS Campeiro' x 'IPR Juriti', and 'BRS Campeiro' x 'IAC Tybatã'. The parents of these hybrids presented high estimates of specific combining abilities. Hybridization of cultivars belonging to distinguished commercial groups propitiates higher heterosis values in the segregant population.

We have recently reported that Notch 1, a member of the Notch multigene family, is essential for the development of murine T cells. Using a mouse model in which Notch 1 is inactivated in bone marrow (BM) precursors we have shown that B cells instead of T cells are found in the thymus of BM chimeras. However, it is not clear whether these B cells develop by default from a common lymphoid precursor due to the absence of Notch 1 signaling, or whether they arise as a result of perturbed migration of BM-derived B cells and/or altered homeostasis of normal resident thymic B cells. In this report we show that Notch 1-deficient thymic B cells resemble BM B cells in phenotype and turnover kinetics and are located predominantly in the medulla and corticomedullary junction. Peripheral blood lymphocyte analysis shows no evidence of recirculating Notch1(-/)- BM B cells. Furthermore, lack of T cell development is not due to a failure of Notch1(-/)- precursors to home to the thymus, as even after intrathymic reconstitution with BM cells, B cells instead of T cells develop from Notch 1-deficient precursors. Taken together, these results provide evidence for de novo ectopic B cell development in the thymus, and support the hypothesis that in the absence of Notch 1 common lymphoid precursors adopt the default cell fate and develop into B cells instead.
