Cet article propose une lecture du « Pseudo-sonnet que les amateurs de plaisanterie facile proclameront le plus beau du recueil » extrait de La Négresse blonde (1909) de Georges Fourest. La démarche de Fourest est mise en relation à la fois avec celle des peintures «monochroïdales » d’Alphonse Allais et avec celle du « sonnet en yx » de Stéphane Mallarmé. Elle est finalement perçue dans toute son ambiguïté, entre la mise en cause radicale de la poésie et la facétie fin de siècle. [less ▲]

In mammals, thyrotropin, or thyroid-stimulating hormone (TSH), assay is used for the diagnosis of primary hypothyroidism. Hypothyroidism is the most common type of thyroid disorder in cattle. The aim of this study was to develop and validate, under physiologic and pathologic conditions, a radioimmunoassay (RIA) for bovine TSH (bTSH). Double RIA was performed with purified bTSH and specific bovine antiserum. Laboratory validation included research of minimal detection limit, accuracy, and reproducibility. The physiologic validation included a thyrotropin-releasing hormone (TRH) challenge performed on euthyroid cows and a follow-up of bTSH concentration over a 24-hour period. Furthermore, bTSH concentration was assayed in a large population of healthy dairy and beef cows to define reference interval. The pathologic validation was made by assaying bTSH and thyroid hormones on healthy and goitrous newborn calves. The minimum detection limit (MDL) for bTSH assay was 1.3 microU/ml. The recovery was 101% to 106%. The intra- and interassay coefficients of variation (CVs) ranged from 5% to 11% and 11% to 15%, respectively. The RIA covered the whole range of physiologic bTSH values, as shown by bTSH values induced by TRH-challenge. A pulsatile secretion of bTSH was observed, accompanied by a diurnal variation with lower night values than day values. Reference intervals of bTSH ranged from 1.3 to 13.0 microU/ml for beef and dairy breeds. Finally, bTSH easily discriminated goitrous newborn calves from healthy ones, leading to the definition of a cutoff value of 35 microU/ml. The bTSH assay positively reacted to physiologic and pathologic conditions. The accuracy and precision of the RIA were satisfying. [less ▲]

When a droplet is gently laid onto the surface of the same liquid, it stays at rest for a moment before coalescence. The coalescence can be delayed and sometimes inhibited by injecting fresh air under the droplet. This can happen when the surface of the bath oscillates vertically. In this case the droplet basically bounces on the interface. The lifetime of the droplet has been studied with respect to the amplitude and the frequency of the excitation. The lifetime decreases when the acceleration increases. The thickness of the air film between the droplet and the bath has been investigated using interference fringes obtained when the system is illuminated by low-pressure sodium lamps. Moreover, both the shape evolution and the motion of the droplet center of mass have been recorded in order to evidence the phase offset between the deformation and the trajectory. A short lifetime is correlated to a small air-film thickness and to a large phase offset between the maximum of deformation and the minimum of the vertical position of the center of mass. [less ▲]

Vu l’intérêt croissant porté par les entreprises aux aspects sociaux et environnementaux, la présente communication propose une revue des principales contributions montrant l’importance et les enjeux de la prise en compte des dimensions sociales et environnementales (de la RSE) dans les systèmes de contrôle de gestion des entreprises. Plus spécifiquement, face aux limites de nombreux outils pour piloter et mesurer adéquatement l’empreinte sociétale des entreprises, ce papier met en évidence les avantages présentés par la Balanced ScoreCard (BSC), un outil de contrôle de gestion développé par Kaplan et Norton (1992) et mondialement connu, pour prendre en compte ces nouvelles dimensions. Cette communication expose ensuite comment cet outil peut éventuellement être adapté afin de prendre en compte ces nouveaux impératifs (sociaux et environnementaux) dans le système de contrôle de gestion traditionnel de l’entreprise. Deux possibilités sont particulièrement envisagées : le découplage ou l’intégration des aspects sociétaux aux aspects traditionnels. Une analyse critique des principaux enseignements des recherches précédentes ainsi que des différentes possibilités d’adaptation de la BSC clôture finalement ce papier. [less ▲]

Over the last decade, polymer micelles and nanoparticles have attracted an increasing interest as efficient drug delivery systems. Polymer micelles from amphiphilic block copolymers are supramolecular core-shell type assemblies of some tens of nanometers in diameter. They are highly stable in aqueous solution because of their low intrinsic critical micelle concentration, which prevents their dissociation upon dilution in the blood stream after intravenous injection. The combination of poly(ethylene oxide) (PEO) with hydrophobic aliphatic polyesters, such as poly(ε-caprolactone) (PCL) or polylactide (PLA), allows to prepare stealthy drug nanocarriers (thanks to PEO), which are biodegradable and biocompatible and capable of encapsulating a hydrophobic drug (due to the aliphatic polyester). In this field, the inclusion of an additional pH-responsive block in the supramolecular assembly is a promising strategy to improve the targeting of tumor tissues by taking advantage of the lower pH at the vicinity of tumor cells. A variety of novel amphiphilic and pH-sensitive copolymers have been synthesized and tested as building blocks for the design of smart nanocarriers able to expose selectively the targeting unit at the vicinity of tumor. Various macromolecular architectures combining PEO, PCL and P2VP have been accordingly synthesized such as linear and star shape di- and triblock copolymers. Their (co)-micellization has been studied in terms of size, particle shape (DLS, TEM) and stealth behavior. Besides, thermo-responsive copolymers combining PEO, polyacrylic acid and poly-N-isopropyl-acrylamide have been synthesized and found efficient in stabilizing stealthy magnetic nanoparticles promising for thermally triggered release of drugs during hyperthermia.

Type I interferon gene induction relies on IKK-related kinase TBK1 and IKK epsilon-mediated phosphorylations of IRF3/7 through the Toll-like receptor-dependent signaling pathways. The scaffold proteins that assemble these kinase complexes are poorly characterized. We show here that TANK/ITRAF is required for the TBK1- and IKK epsilon-mediated IRF3/7 phosphorylations through some Toll-like receptor-dependent pathways and is part of a TRAF3-containing complex. Moreover, TANK is dispensable for the early phase of double-stranded RNA-mediated IRF3 phosphorylation. Interestingly, TANK is heavily phosphorylated by TBK1-IKK epsilon upon lipopolysaccharide stimulation and is also subject to lipopolysaccharide- and TBK1-IKK epsilon-mediated Lys(63)-linked polyubiquitination, a mechanism that does not require TBK1-IKK epsilon kinase activity. Thus, we have identified TANK as a scaffold protein that assembles some but not all IRF3/7-phosphorylating TBK1-IKK epsilon complexes and demonstrated that these kinases possess two functions, namely the phosphorylation of both IRF3/7 and TANK as well as the recruitment of an E3 ligase for Lys63-linked polyubiquitination of their scaffold protein, TANK.

Previous research has shown that the ability to organize information for remembering in an intentional and strategic way is impaired in schizophrenia patients (Rizzo et al., 1996) and that the remembering is accompanied by a low level of autonoetic awareness (Danion et al., 1999). Chronic and heavy uses of cannabis induce cognitive impairments. These impairments persist while the user remains intoxicated, and may or may not be reversible after prolonged abstinence from cannabis (Lundqvist, 2005). The aim of the present study was to investigate whether past cannabis use may reduce more subtle deficits in neurocognitive functioning such as deficit of the specificity of autobiographical memories and the associated level of autonoetic awareness in a population of schizophrenia patients. The TEMPau (Piolino, 2000) was used to evaluate the autobiographic memory and the level of autonoetic consciousness. Participants were asked to generate 3 specific memories for four life periods (0-9 years old, 10-19 years old, after 20 years old and the last 12 months). Performances from 6 past cannabis use schizophrenia patients were compared to performances of 8 schizophrenia patients no users. Patients were not treated with benzodiazepines. The analysis revealed a significant group difference for the 10-19 years old period for the specificity of autobiographical memories ( t2,11 = 2.3 ; p = 0.041). Past cannabis users reported less specific events (m = 6.83 (1.94)) compared to the no users patients (m = 9.14 (1.67)). The implications of this result will be discussed. [less ▲]

A previous study conducted in Belgium revealed that genetic material of Fasciola sp. was present in snail species belonging to the genus Radix. Here, these snails were collected and identified by DNA-based techniques as Radix labiata and Radix balthica. These two species and Galba truncatula (the major intermediate host in Europe) were experimentally infected with Fasciola hepatica. The resulting metacercariae were fed to rats and the infection was monitored using several techniques. Microscopy revealed the presence of larval stages in 78.3, 45, and 6.25% of G. truncatula, R. labiata, and R. balthica snails, respectively. These results were confirmed by a PCR that amplifies a Fasciola sp. specific sequence. Furthermore, this PCR was found to be more sensitive than microscopic examination. R. labiata shed fewer metacercariae than G. truncatula but these were as infective to rats as those shed by G. truncatula. This study demonstrates that R. labiata may act as an incidental intermediate host for F hepatica in Belgium. (C) 2007 Elsevier B.V. All rights reserved. [less ▲]

502 --- Attempt to classify main descriptors of GP/FM job. Proposal for a metaclinical classification Marc Jamoulle. marc@jamoulle.com metaclinical provisional web site Context: ICPC use is growing in any domain of GP/FM. Widely accepted as clinical tool; it is also used in various ways in practice management such as immunization targeting, documentation indexing or clinical messaging. Its components, RFE/Process/Appreciation allow a quite interesting conceptual representation of GP/FM clinical activities. Nevertheless, family doctor work area and work load need specific descriptors in order to fulfil the following objectives Objectives: Global description of activity, skills and knowledge (except health problems, procedure and diseases) Classification complementary to ICPC (expanded from Q codes Lamberts et all, circa 1987). Descriptors needed for indexation. Main axes of training for undergraduate and vocational All those items aim to describe the content of GP/FM in its non clinical approach. They constitute meta-information on the way the clinics and the patient doctor relationships are driven. That’s why I have chosen to use the name metaclinical classification for describing this tool. Methods: The Q codes, developed by Lamberts at all circa 1987 for use in bibliographic retrieval in Amsterdam University (UVA) department of GP/FM form the first building blocks of the classification. The Q letter has been chosen because it is not used in ICPC. This first approach has been filled up with my personal experience along 30 years of practice, research and teaching. From this as an empirical document, one try to change, fill the gaps and modify the content of the classification using publication on GP/FM, pair experience and critics and application to real work. UMLS corresponding descriptors searching and indexation exercises on published document could be also a good way to verify the applicability of the classification.
