Economic evaluations of animal health surveillance systems are critical components of the assessment of their long-term sustainability and the improvement of their cost- effectiveness. Social costs and benefits of health information release through the surveillance systems are fundamental determinants of the acceptability and efficacy of surveillance and are often neglected in the evaluation process. This study presents the evaluation of social costs and benefits of Highly Pathogenic Avian Influenza (HPAI) surveillance in Vietnam. Three field studies were conducted in the South and North of the country. Data on animal health information flow networks and social costs and benefits were collected using participatory approaches. Non-monetary costs and benefits were quantified using a newly developed tool based on stated choice method and participatory techniques. The study showed that private actors incur many transaction costs in reporting the information. However social costs mainly arise from price drops due to information release on market which has strong influences on the decision to disclose sanitary information. This applies at all levels including farmers and veterinary authorities. Private actors of the poultry sector valued information on occurring disease outbreaks, which is perceived as a social benefit. However avian influenza information is scarcely disclosed in private networks as stakeholders fear its potential impact on markets. [less ▲]

Background: SV2A is the most studied isoform of the Synaptic Vesicle 2 proteins, which are involved in the synaptic vesicle trafficking, being important in normal and pathological process, like the epilepsy (1, 2). [18F]UCB-H was developed like a tool to study the role of this isoform with neuroimaging techniques (3, 4). The objective of this study was to evaluate its specificity to this isoform comparing with the others, through a competition assay in rats with ex-vivo autoradiography and mPET imaging. Methods: Forty male Sprague-Dawley were used in ex-vivo autoradiography experiments (N=20) and in microPET imaging (N=20). Animals were pre-treated 30 minutes before the injection of [18F]UCB-H with a dose IP either of vehicle, Keppra (SV2A ligand), UCB068 (SV2B ligand) or UCB054 (SV2C ligand). Ex-vivo autoradiography was carried out 5 minutes after radiotracer injection while mPET images were acquiring with a dynamic scanner of 1 hour. Data were expressed in Standard Uptake Value and then, the area under the curve was calculated for the total process. Results: In ex-vivo autoradiography, ANOVA of two-ways showed statistical significant differences in brain uptake of [18F]UCB-H among the groups pretreated with Keppra or the ligand for SV2B and the control group. Regarding mPET data, statistical significant differences were found between the group injected with keppra and the rest of groups. Conclusion: Even if a considerable affinity between the ligands UCB068 and UCB054, and the receptor for the isoform SV2A exists, it is only detected during the first 5 minutes (ex-vivo technique), being certainly due to a nonspecific binding. This binding is not strong enough to show a direct competition with the radiotracer during a mPET acquisition. These results allow us to conclude that [18F]UCB-H is a suitable radiotracer for the imaging of the isoform SV2A in vivo, allowing us the clinical study about the molecular base of a disease with a high population impact, like the epilepsy.

Volatile organic compounds (VOCs) are considered to be priming agents in plant responsive defense to protect themselves against abiotic or/and biotic stresses. Such stresses often influence on plant photosynthesis and defense responses, resulting in a variety of volatile profiles. We investigated how different temperature regimes affect the VOCs emission capacity of Arabidopsis thaliana Col-0 (A.t Col-0) in the presence and absence of a sucking insect – Myzus persicae (green peach aphid). VOCs analyses were made with solid-phase micro-extraction coupled with gas chromatography - mass spectrometry (SPME- GC/MS) under controlled and various stress treatments. In response to temperature stresses, alcohols, ketones, aldehydes and terpenes were the most emitted VOCs. Moreover, the compared results showed that the percent emission of several compounds changed significantly. The interaction between temperature stresses and aphids released some new volatile components; like isothiocynates, esters, sulfur compound and nitrile. Besides, the qualitative and overall proportion of volatile blends differed significantly from plants subjected to the stress treatments within different time intervals (0-24h; 24-48h and 48-72h). Overall, both stress treatments correlated with increased or decreased levels of VOCs classes from Arabidopsis shoot organs. Knowledge of how the temperature – aphids interaction influences on VOCs emission in this study also provides interesting information for evaluating the responsive resistance in plants under natural environments.

Le cours de Médecine Palliative est dispensé aux étudiants en avant-dernière année des études médicales de 2e cycle par deux enseignants, Médecin Généraliste et Médecin Hospitalier. Ce cours est dispensé depuis 10 ans selon un format traditionnel ex cathedra. De nouveaux objectifs et de nouvelles modalités pédagogiques ont été introduits en 2010-2011. L’objectif principal est l’apprentissage réflexif des étudiants. Les outils pédagogiques sont le portfolio électronique, une vignette clinique évolutive, l’accompagnement à distance de chaque étudiant par un tuteur, des cours en présentiel. La pratique réflexive de chaque étudiant est évaluée au terme du dispositif selon des critères et des indicateurs préalablement communiqués. Des perspectives ont émergé sur base des analyses des forces et faiblesses. [less ▲]

Neurophysiological testing has become a valuable tool for investigating brain excitability and nociceptive systems in headache disorders. Previous reviews have suggested that most neurophysiological tests have limited value for headache diagnosis, but a vast potential for exploring the pathophysiology of headaches, the central effects of certain pharmacological treatments and phenotype-genotype correlations. Many protocols, however, lack standardization. This meta-analytical review of neurophysiological methods in migraine was initiated by a task force within the EUROHEAD project (EU Strep LSHM-CT-2004-5044837-Workpackage 9). Most of the neurophysiological approaches that have been used in headache patients are reviewed, i.e. evoked potentials, nociception-specific blink reflex, single-fibre electromyography, neuroimaging methods (functional MRI, PET, and voxel-based morphometry) and the nitroglycerin attack-provoking test. For each of them, we summarize the results, analyse the methodological limitations and propose recommendations for improved methodology and standardization of research protocols. The first part is devoted to electrophysiological methods, the second to neuroimaging techniques and the NTG test. [less ▲]
