Au terme du cours consacré à la recherche d’informations scientifiques - au programme des bacheliers de la Faculté de Médecine vétérinaire et de la Faculté de Psychologie, Logopédie et des Sciences de l’Éducation (Université de Liège) - les étudiants doivent avoir une vue d’ensemble de la publication scientifique et être capables de (i) mener de manière autonome une recherche d’informations et (ii) de citer correctement leurs sources en respectant des normes bien précises lors de la rédaction de documents. L’évaluation de ce cours est contraignante car il s’agit de cohortes d’étudiants de plus en plus grandes (> 300 étudiants par cursus). Comment évaluer les connaissances ainsi que les savoir-faire de grands groupes d’étudiants ? Jusqu’alors l’examen se composait de questions ouvertes et nécessitait que chaque étudiant ait à sa disposition un ordinateur connecté à Internet. Cette méthode requérait une logistique importante avant et pendant l’examen ainsi que des semaines de correction. Plusieurs alternatives à cette évaluation ont alors été envisagées : travail individuel, travail de groupe, questionnaire à choix multiple… mais elles ne répondaient pas aux exigences fixées par les compétences à évaluer. La piste retenue pour cette nouvelle année académique reste contraignante du point de vue organisationnel (ordinateur pour chaque étudiant) mais permet une correction standardisée, automatisée, fiable et rapide. En effet, le questionnaire combine désormais des questions à choix multiple (QCM ; jusqu’à 9 propositions de réponses) et des questions à choix large (QCL ; jusqu’à 999 propositions). Le QCL présente l’avantage d’être proche de l’évaluation à l’aide de questions ouvertes sans les désavantages de la correction. Nous proposons de présenter ce dispositif évaluatif ainsi que ses avantages et inconvénients par rapport à d’autres méthodes d’évaluation. [less ▲]

Aims The aim of this study was to evaluate the impact of “VeinoPlus Sport” on amateur soccer players’ recovery after an intense physical activity (2 drills). Method We proceeded to a comparative study between two devices: “VeinoPlus Sport” and “TENS” (used as a control system) on a population of 20 players (average age 17,1±0,8). Under identical conditions each player used the two devices during two separate sessions (called group “VeinoPlus Sport” and group “TENS”). The players performed an intense effort following the YoYo test concept. Four blood samples were taken from each participant and a Myotest evaluation was performed: one before the test, one just after the first intense effort, another after a short recovery time following the first effort, and the last one right after the second intense effort. For statistical analysis, we used the Anova algorithm of the “StatPlus” system and a Scheffé test. Results With both devices, we observed a significant elevation of lactate, HCO3− ions, and myoglobin as time progressed. The analysis of other blood parameters did not show any significant evolution in the course of the testing. The “VeinoPlus Sport” group, after the session, expressed feeling lighter and more fit than usual following an intense physical activity. They did not suffer any pain, tiredness, nor diminishment of strength. The same observation was made with the “TENS” group with the exception that some players felt a bit of soreness in their thigh and calf areas. In general, all participants admitted preferring the use of recovery machines instead of natural recovery. At the same time, none expressed any preferences between either of the devices. Conclusion The main asset of this study resided in the highlighting of minor differences as no way significant between the two machines tested on the chosen population. The “TENS” shows similar results as the “VeinoPlus Sport” even if a slight preference for the latter was expressed. Both devices permitted an equal or even better performance in the second drill in comparison to the first drill. [less ▲]

Owing to the reduction of population density and/or the environmental changes it induces, selective logging could affect the demography, reproductive biology and evolutionary potential of forest trees. This is particularly relevant in tropical forests where natural population densities can be low and isolated trees may be subject to outcross pollen limitation and/or produce low-quality selfed seeds that exhibit inbreeding depression. Comparing reproductive biology processes and genetic diversity of populations at different densities can provide indirect evidence of the potential impacts of logging. Here, we analysed patterns of genetic diversity, mating system and gene flow in three Central African populations of the self-compatible legume timber species Erythrophleum suaveolens with contrasting densities (0.11, 0.68 and 1.72 adults per ha). The comparison of inbreeding levels among cohorts suggests that selfing is detrimental as inbred individuals are eliminated between seedling and adult stages. Levels of genetic diversity, selfing rates (∼16%) and patterns of spatial genetic structure (Sp ∼ 0.006) were similar in all three populations. However, the extent of gene dispersal differed markedly among populations: the average distance of pollen dispersal increased with decreasing density (from 200m in the high-density population to 1000m in the low-density one). Overall, our results suggest that the reproductive biology and genetic diversity of the species are not affected by current logging practices. However, further investigations need to be conducted in low-density populations to evaluate (1) whether pollen limitation may reduce seed production and (2) the regeneration potential of the species.

Machine learning models have been successfully applied to neuroimaging data to make predictions about behavioral and cognitive states of interest. While these multivariate methods have greatly advanced the field of neuroimaging, their application to electrophysiological data has been less common especially in the analysis of human intracranial electroencephalography (iEEG, also known as electrocorticography or ECoG) data, which contains a rich spectrum of signals recorded from a relatively high number of recording sites. In the present work, we introduce a novel approach to determine the contribution of different bandwidths of EEG signal in different recording sites across different experimental conditions using the Multiple Kernel Learning (MKL) method. To validate and compare the usefulness of our approach, we applied this method to an ECoG dataset that was previously analysed and published with univariate methods. Our findings proved the usefulness of the MKL method in detecting changes in the power of various frequency bands during a given task and selecting automatically the most contributory signal in the most contributory site(s) of recording. With a single computation, the contribution of each frequency band in each recording site in the estimated multivariate model can be highlighted, which then allows formulation of hypotheses that can be tested a posteriori with univariate methods if needed.

Formic acid (HCOOH) is one of the most abundant volatile organic compounds in the atmosphere. It is a major contributor to rain acidity in remote areas. There are however large uncertainties on its sources and sinks, and HCOOH is misrepresented by global chemistry-transport models. This work presents global distributions from 2008 to 2014 as derived from the measurements of the Infrared Atmospheric Sounding Interferometer (IASI), based on conversion factors between brightness temperature differences and representative retrieved total columns over seven regions: Africa N, Africa S, Amazonia, Atlantic, Australia, Pacific and Russia. The dependence of the thermal contrast is taking account in the conversion method. This conversion presents errors lower than 20 % for total columns ranging between 0.5 and 1 × 1016 molec/cm2 but reaches higher values, up to 78 %, for columns lower than 0.3 × 1016 molec/cm2. Signatures from biomass burning events are highlighted, such as in the Southern Hemisphere and in Russia, as well as biogenic emission sources, e.g. over Eastern US. A comparison between 2008 and 2014 with ground-based FTIR measurements obtained at 4 locations (Maido and Saint-Denis at La Réunion, Jungfraujoch and Wollongong) is shown. Although IASI columns are found to correlate well with FTIR data, a large bias (> 100 %) is found over the two sites at La Réunion. A better agreement is found at Wollongong with a negligible bias. The comparison also highlights the difficulty for IASI to retrieve the total columns over mountainous regions such as Jungfraujoch. A comparison of the retrieved columns with the global chemistry-transport model IMAGESv2 is also presented, showing the good representation of the seasonal and inter-annual cycles over America, Australia, Asia and Siberia. A global model underestimation of the distribution and a misrepresentation of the seasonal cycle over India are also noted. A small positive trend in the IASI columns is also observed over Australia, Amazonia and India over 2008–2014 (from 0.7 to 1.5 %/year), while a decrease of ~ 0.8 %/year is measured over Siberia.

Aims. The main-sequence B-type star zeta Cassiopeiae is known as a N-rich star with a magnetic field discovered with the Musicos spectropolarimeter. We model the magnetic field of the star by means of 82 new spectropolarimetric observations of higher precision to investigate the field strength, topology, and effect. Methods. We gathered data with the Narval spectropolarimeter installed at Télescope Bernard Lyot (TBL; Pic du Midi, France) and applied the least-squares deconvolution technique to measure the circular polarisation of the light emitted from zeta Cas. We used a dipole oblique rotator model to determine the field configuration by fitting the longitudinal field measurements and by synthesizing the measured Stokes V profiles. We also made use of the Zeeman-Doppler imaging technique to map the stellar surface and to deduce the difference in rotation rate between the pole and equator. Results. zeta Cas exhibits a polar field strength B_pol of 100-150 G, which is the weakest polar field observed so far in a massive main-sequence star. Surface differential rotation is ruled out by our observations and the field of zeta Cas is strong enough to enforce rigid internal rotation in the radiative zone according to theory. Thus, the star rotates as a solid body in the envelope. Conclusions. We therefore exclude rotationally-induced mixing as the cause of the surface N-enrichment. We discuss that the transport of chemicals from the core to the surface by internal gravity waves is the most plausible explanation for the nitrogen overabundance at the surface of zeta Cas.

Context: Hypoxic-Ischemic encephalopathy (HIE) remains a major cause of perinatal brain injury. The brain rapidly increases in size, shape and complexity during the second and third trimesters. A sentinel event in late pregnancy or the intrapartum period may have an acute profound effect on a previously neurologically intact fetus, leading to the development of (HIE). The nature of the deficits is dependent on the gestational age and severity of the insult, though it is seldom reported in preterm infants. Studies in animal models of HIE may provide important information for the development of treatment for this pathological condition. Estetrol (E4) is a recently described estrogen with four hydroxyl-groups that is synthesized exclusively during pregnancy by the human fetal liver. Objective: In this study, we evaluated E4’s neuroprotective and therapeutic potency in neonatal (in vivo) HIE model of the immature 7-day-old newborn rat. Methods: Rat pups body temperatures were examined along with their body and brain weights. Brains were studied at the level of the hippocampus and cortex. Intact cell counting and expressions of markers for neuronal early grey matter damage (microtubule-associated protein-2 (MAP-2)), neurogenesis (doublecortin (DCX)) and angiogenesis (vascular-endothelial growth factor (VEGF)) were evaluated by histo- and immunohistochemistry. The serum levels of two markers of brain damage (S100B and glial fibrillary acidic protein (GFAP)) were measured by ELISA. Results: Our results demonstrate that E4 has a significant neuroprotective and therapeutic effects. Estetrol decreases the early gray matter loss, and promotes neuro- and angiogenesis in vivo. Estetrol treatment has no effects on body weight, brain weight or body temperature. Conclusion: Taken together, E4 might become an important safe and physiological substance to treat neonatal HIE.
