Taking into account structure-activity relationships obtained with our previous series, new diversely substituted 1,2,4-pyridothiadiazine 1,1-dioxides were designed to obtain novel AMPA potentiators. The aim of this work was focused on the improvement of lipophilicity, which is well known as a critical parameter to obtain in vivo active central nervous system agents. For this purpose, two positions on the pyridine ring were privileged to insert selected groups. Among the synthesized compounds emerged 7-chloro-4-ethyl-3,4-dihydro-2H-pyrido[2,3-e]-[1,2,4]-thiadiazine 1,1-dioxide (12d), which was evaluated in two memory tests in Wistar rats and showed cognition enhancing effects after intraperitoneal injection at doses as low as 0.3mg/kg.

The Chilean Lake District (38-42 degrees S) is strongly influenced by Southern westerlies-driven precipitations. At 40 degrees S Lago Puyehue provides high resolution sedimentation rates (similar to 1-2 mm/yr) suitable for annual climate reconstruction. Several short and long sediment cores were collected in this lake. Their analysis aim at a better understanding of climate mechanisms related to ENSO in this part of the world. The recognition of ENSO related periodicities and their stability is studied through the analysis of two short varved cores collected from underflow and interflow key sites. According to varve chronology controlled by Cs-137 and Pb-210 profiles and chronostratigraphical markers, the short core from underflow site (PU-I) spans 294 +/- 18 years and the core in the interflow site (PU-II) covers 592 +/- 9 years. Several methods of spectral analysis were applied on the total varve thickness to identify potential periodicities in the signal. Blackman-Tuckey, Maximum Entropy, Multi-Taper Methods (MTM) and singular spectrum analysis were applied on the whole record. In addition, evolutive MTM and wavelet analyses allow to identify temporal influence of some periodicities. In the PU-I studied interval (AD 1700-2000), a period at similar to 3.0 years appears in a large part of the interval, mostly in the recent part. Periods at similar to 5.2 and similar to 23 years also show up. PU-II record (AD 1400-2000) displays the most robust periodicities at around 15, 9, 4.4, 3.2 and 2.4 years. These periodicities are in good agreement with the sub-decadal periods identified by Dean and Kemp (2004) and linked to the El Nino Southern Oscillation and the Pacific Decadal Oscillation. Differences in the recorded periodicities between PU-I and PU-II sites are consistent with different sedimentation processes in the lake. According to climate instrumental data for the last 20 years, varves in PU-I site are mostly related to fluvial dynamics and regional climate factors, i.e., precipitation, temperature and wind. In PU-II site, varves increment is related to both regional and global climate forcing factors, i.e., El Nino Southern Oscillation. The evolutive MTM analysis and the wavelet analysis suggest a striking break in the periodicities at around AD 1820. Finally relationships between El Nino and longer term climate phase like the Little Ice Age (LIA) are also assessed. [less ▲]

This paper examined the structural model of subjective stress considering the job control dimensions of the WOrking Conditions and Control Questionnaire (WOCCQ), a psychosocial risk diagnosis widely used in French-speaking countries. Two research questions were investigated: (1) Do all the control facets influence subjective stress in the same way?, and (2) Are certain control scales more important than others in the prediction of stress? The sample used includes 816 workers of a public employment agency. First, not all of the facets of job control influence stress in the same way. The control of resources dimension is important in indirectly influencing the stress process. Planning control is a partial mediator between control of resources and other dimensions of control. The model suggests considering future control as an exogenous variable. Finally, the direct effect of the four job control subscales on stress is identical in terms of R-square. These results are discussed not only in the theoretical perspective of stress at work but also in the stress intervention perspective. [less ▲]

Le chapitre s’efforce de situer les enjeux épistémologiques de la « sociologie de la traduction » associée aux travaux de Michel Callon et de Bruno Latour. Tout en s’inscrivant dans le prolongement du « programme fort » en sociologie des sciences, dont elle reprend certains principes de méthode (impératif d’enquête sur le terrain, recherche d’une « symétrie » dans l’explication du vrai et du faux, étude du « noyau dur » des pratiques scientifiques plutôt que des institutions et des trajectoires de savants), la sociologie de la traduction s’en émancipe cependant par le souci de prendre en compte les objets dans la description, en les dotant d’une véritable capacité « actantielle ». L’argument soutenu par les auteurs est qu’en « généralisant » de la sorte le principe de symétrie et en dotant leur sociologie d’un ancrage narratologique, Callon et Latour sont passés d’un modèle strictement causal d’explication à un principe descriptif fondé sur la seule cohérence narrative. Construite pour rendre compte de processus complexes (la science « en train de se faire ») où sont redéfinies la réalité et l’identité mêmes des entités qui y sont engagés, la notion de « traduction » devient ainsi le mécanisme de base d’un « répertoire » ou métalangage de description, dont le chapitre articule les principales notions (actants humains et non-humains, acteur-réseau, porte-parole, épreuve…). L’exemple commenté d’une recherche de Latour sur le sol amazonien montre toute l’importance des activités pratiques de prélèvement, de classement et de marquage dans le passage des choses aux signes et des signes aux textes que permet le laboratoire, dès lors saisi comme dispositif d’inscription littéraire. Les auteurs concluent ce portrait contrasté d’un courant toujours controversé en insistant sur les vertus méthodologiques de la notion de répertoire ; ils tempèrent ainsi quelque peu l’accusation de relativisme qui continue de peser sur cette sociologie, sans manquer d’en relever les ambiguïtés, notamment quant au renouvellement de l’ontologie proposé par Latour.

European nitrate directive (CEE/91/676) imposes wide monitoring of Nitrogen in farmlands. The Walloon Region (South of Belgium – 750 000 ha of arable land) develops an original combination of methods to reach European objectives in this topic. On the one hand, water and nitrogen flows and balances are modelled, on the other hand, an Agricultural Surface Survey is put into practice to monitor nitrate nitrogen in the soil at the beginning of the leaching period. The Agricultural Surface Survey is constituted by a 30 reference farms network within more than 200 plots are monitored each in order to fix annual standards for nitrate profiles. Each year, about 1% of the Walloon farms are assessed about their good nitrogen management. Thanks to the existence of a useful database of nitrate profiles measured through six years in the whole Walloon Region, validation of the simulations in the vadose zone can be realised. The comparison of the measured data and the simulation shows a good accuracy of the EPICgrid model. [less ▲]

Primary gastric lymphoma is a rare event in childhood. We describe a 13-year-old boy with gastric Burkitt-like lymphoma localized in the fundus. Symptoms mimicking gastritis-epigastric pain, hypochromic anemia, anorexia, and weight loss had been present for a few months before diagnosis. No Helicobacter pylori infection was shown at diagnosis. Biopsies obtained by ultrasound gastroscopy proved the diagnosis; F-fluorodeoxyglucose-positron emission tomography detected an isolated large gastric hypermetabolic mass. According to the international FAB/LMB 96 trial, the patient was treated with chemotherapy alone and is in first complete remission 2(1/2) years after diagnosis. [less ▲]
