Many studies already investigated the impact of climate change and climate variability on vegetation at global and continental scales. Using time series of remote sensing and climate data, Nemani et al. (2003) analyzed trends in Net Primary Production in relation with changes in climate and showed that, between 1982 and 1999, primary productivity increased by 6% globally in response to climate change. This study also stressed the need to take into account the spatial variability of climatic constraints to plant growth when analyzing the climate change impact on vegetation. Others authors described different phenomenon linked with climate change such as increases of seasonal NDVI amplitude and growing season duration in the Northern high latitude or changes in circumpolar photosynthetic activities. Understanding the interactions between climate and vegetation is also a key issue in our PhD research. Our objective is to identify the meteorological factors which limit the development of croplands and grasslands in relation with their geographical localization. For that purpose, we acquired 10-daily time series of the Normalized Difference Vegetation Index, NDVI, derived from SPOT-VEGETATION and 7 meteorological parameters (Tmean, Tmin, Tmax, Rain, Rad, ETP, Rain-ETP) derived from ERA40 re-analyses and the operational ECMWF (European Centre for Medium-Range Weather Forecast) atmospheric model. Cross-correlations between NDVI and each one of the meteorological parameters were analysed for a set of 25 regions over Europe and Africa: 15 agricultural regions and 10 regions covered by grassland or savannas. Unlike others studies, we did not consider the vegetation globally but we focussed on two types of vegetation: croplands and grasslands. This is quite important considering the role of phenology on the vegetation cycle and its relation with climate. Moreover the analysis was not realised using yearly estimates but using 10-daily products. In order to avoid stationarity related issue, a specific methodology was developed taking into account the phenological cycle of the vegetation under consideration. Preliminary results showed that the relation between a meteorological limiting factor, e.g. precipitation, and NDVI can not be considered as linear during the year or even during the growing season. Interactions must to be studied at a smaller time scale than the growing season in order to identify properly the limiting factors to plant growth taking into account its phenology. Moreover the main limiting factors are variable from a region to another. In our analysis we also considered the possibility of a delayed response of the vegetation or a cumulated effect of meteorological events (up to 3 months). Our methodology will be presented during the conference and results will be discussed and illustrated by some test cases. [less ▲]

Nous présentons ici 5 tours de magie ne nécessitant aucune habileté particulière de la part de l'apprenti magicien : des tours de cartes, des tours de divination et le célèbre tour du ``barman aveugle avec des gants de boxe''. Contrairement au magicien qui ne dévoile jamais ses secrets, ici, nous expliquons que ces tours reposent sur diverses propriétés et constructions mathématiques. Ces dernières débouchent sur de véritables questions de recherche actuelle en théorie des graphes ou en combinatoire des mots et même sur de possibles applications en robotique et automatisation ! Il y en aura donc pour tous les goûts... et tous les niveaux (suivant l'auditoire, l'exposé sera adapté au niveau des élèves de la 4ième à la 6ième secondaire, voire même aux étudiants universitaires). Ce texte présente donc un matériel qui dépassera souvent (et de loin) le ``spectacle''. [less ▲]

OBJECTIVES: To examine how geriatric evaluation and management units (GEMUs) are organized and to examine the effectiveness of admission on a GEMU. DESIGN: Systematic review and meta-analysis based on literature search of multiple databases and the references lists of all identified articles and by contacting authors. SETTING: GEMUs. PARTICIPANTS: Elderly people admitted to a GEMU. MEASUREMENTS: Quality of the studies was assessed on 10 criteria. The outcome parameters were mortality, institutionalization, functional decline, readmission, and length of stay at different follow-up points. A random-effects meta-analysis was performed using Hedges' gu and variance of relative risk (RR). RESULTS: GEMUs are organized in a heterogeneous way and the included studies gave no thorough description of comprehensive geriatric assessment (CGA). Involvement of a multidisciplinary team was a key element in all GEMUs. The individual trials showed that admission to a GEMU has one or more favorable effects on the outcomes of interest, with two significant effects in the meta-analysis: less functional decline at discharge from the GEMU (RR=0.87, 95% confidence interval (CI)=0.77-0.99; P=.04) and a lower rate of institutionalization 1 year after discharge (RR=0.78, CI=0.66-0.92; P=.003). For the other outcomes in the meta-analysis, a GEMU did not induce significantly different outcomes than usual care. CONCLUSION: This meta-analysis shows a significant effect in favor of the GEMU group on functional decline at discharge and on institutionalization after 1 year. There is heterogeneity between the studies, poor quality of some randomized controlled trials, and shortage of information about CGA. Multidisciplinary CGA offered in a GEMU may add value to the care for frail older persons admitted to the hospital, but the limitations confirm the need for well-designed studies using explicit CGA and more-structured and -coherent assessment instruments such as the Minimum Data Set Resident Assessment Instrument.

Lactivicin (LTV) is a natural non-beta-lactam antibiotic that inhibits penicillin-binding proteins and serine beta-lactamases. A crystal structure of a BS3-LTV complex reveals that, as for its reaction with PBPs, LTV reacts with the nucleophilic serine and that cycloserine and lactone rings of LTV are opened. This structure, together with reported structures of PBP1b with lactivicins, provides a basis for developing improved lactivicin-based gamma-lactam antibiotics. [less ▲]

Objectives: To evaluate electromyogram (EMG) profiles in patients with three related conditions: fibromyalgia, chronic fatigue syndrome, and depression. Methods: We studied 44 healthy volunteers, 22 patients with fibromyalgia, 11 patients with chronic fatigue syndrome, and 10 patients admitted for depression. The trapezius electromyogram was recorded during maximally sustained, bilateral, 90◦ abduction of the shoulders. EMG signal frequency and amplitude were measured throughout the test. Results: In the fibromyalgia group, isometric contraction duration was significantly shorter than in the other two patient groups (P < 0.001) and the EMG frequency and amplitude pattern indicated premature discontinuation of the muscle contraction. Findings in the chronic fatigue patients were similar to those in the healthy controls. The patients with depression had a distinctive EMG profile characterized by excessive initial motor-unit recruitment with a shift in the frequency spectrum. Conclusions: Fibromyalgia was associated with a specific EMG pattern indicating premature discontinuation of the muscle contraction. Therefore, maximal voluntary muscle contraction tests may be of limited value for assessing function in fibromyalgia patients. Chronic fatigue syndrome patients had similar EMG findings to those in the healthy controls. The EMG alterations in the patients with depression were consistent with manifestations of psychomotor retardation. [less ▲]

La compatibilité – ou appétence - entre un système de réparation et le béton support est définie à partir des propriétés du support et de la couche d’apport – essentiellement dans sa phase non liée – ainsi que de l’environnement dans lequel le contact est créé. Elle s’exprime habituellement en termes de variations dimensionnelles, de perméabilité et de propriétés chimiques et électrochimiques. Ces propriétés sont évoquées ou développées pour chacun des matériaux mis en présence : rugosité, porosité, cohésion superficielle et eau interstitielle pour le béton ; retrait, fluage, rigidité, absorption capillaire pour les produits de réparation. Trois conditions fondamentales nécessaires et suffisantes au développement de l’adhérence en tant que signe de la compatibilité entre matériaux sont évoquées et illustrées pour le cas particulier de la préparation de surface : sablage, burinage, hydro démolition, marteau-piqueur, … ont un effet spécifique non seulement sur la rugosité, et donc l’accrochage mécanique du système de réparation, mais aussi sur la cohésion de la couche superficielle du béton [less ▲]

The impact of concomitant rhinitis on asthma-related quality of life and asthma control. Allergy 2010; DOI: 10.1111/j.1398-9995.2010.02365.x. Abstract Background: Characterizing the interactions between the upper and lower airways is important for the management of asthma. This study aimed at assessing the specific impact of concomitant rhinitis on asthma-related quality of life (QOL) and asthma control. Methods: A cross-sectional, observational survey was conducted among 1173 patients with asthma (aged 12-45) recruited by general practitioners and chest physicians. AR was defined by self-reported rhinitis symptoms and previously documented sensitization to inhalant allergens. The primary outcomes were (1) asthma control assessed by the Asthma Control Questionnaire (ACQ) and (2) asthma-specific QOL evaluated through the Mini Asthma Quality of Life Questionnaire (mAQLQ). Results: AR was present in 73.9% of the population with asthma and nonallergic rhinitis (NAR) in 13.6%. AR and NAR were associated with an increased risk of uncontrolled asthma (i.e. ACQ score > 1.5) with adjusted odds ratios (OR) of 2.00 (95% confidence interval [CI]: 1.35-2.97) and 1.77 (95%CI: 1.09-2.89), respectively. Multivariate linear regression analysis showed that AR and NAR had a modest, although significant, negative impact on the global mAQLQ score (beta coefficient: -0.293, standard error [SE]: 0.063 and beta coefficient: -0.221, SE: 0.080, P < 0.001, respectively), even after adjustment for the level of asthma control and demographic characteristics. Conclusion: This survey provides direct evidence that AR and NAR are associated with an incremental adverse impact on the disease-specific QOL of patients with asthma and the level of asthma control. Further investigations are required to determine whether appropriate treatment of rhinitis would efficiently reduce asthma morbidity. [less ▲]
