The di erential e ects of basic visual or auditory stimuli on electroencephalograms (EEG), named event related potentials (ERPs), are often used to evaluate the impact of treatments on brain performances. In the present paper, we propose a P-splines based model that can be used to evaluate treatment e ect on the timing and the amplitude of some peaks of the ERPs curves. Functional ANOVA is an adaptation of linear model or analysis of variance to analyse functional observations. The changes in the functional of interest e ects are generally described using smoothing splines. Eilers and Marx proposed to work with P-splines, a combination of B-splines and di erence penalties on coe cients. We de ne a Psplines model for ERPs curves combined with random e ects. In particular, we show that it is a useful alternative to classical strategies requiring the visual and usually imprecise localization of speci c ERP peaks from curves with a low signal-to-noise ratio.

In May 2006 comet 73P/SW3 passed at less than 0.1 AU from Earth providing us an unique opportunity for high spatial resolution study of its coma. This event was expected to be particularly interesting because the comet had broken apart in 3-4 fragments in 1996. The 2006 apparition has been even more interesting because the fragments produced in 1996, when approaching the Sun, were continuously breaking apart. This process resulted in many small sub-fragments and in the injection in the coma of fresh material, coming from the interior of the nuclei, giving the possibility to study this uncontaminated material. The breaking fragments have been observed at ESO in the visible and near-IR with the aim of analyzing this fresh solid component of the coma in search of possible presence of organic solids. In the presentation we will report preliminary results of this campaign. [less ▲]

Adaptation to pregnancy involves major maternal anatomical, physiological and metabolic modifications to support the mother's metabolic needs and those of the growing foetus. Invasion of embryonic territories and implantation in humans and other mammals is the result of an active biochemical process. The invasive faculty of cytotrophoblastic cells depends on their capacity to secrete proteolytic enzymes such as matrix metalloproteinases (MMPs). Many studies have addressed the variations in MMPs in placental tissues, but few have reported on their measurements in plasma. Furthermore, the Pregnancy-Associated Glycoproteins (PAGs), which are synthesized in the syncytiotrophoblast and used as early markers of pregnancy in domestic and wild animals, have not yet been studied in rabbits. In this study, we attempt to purify PAGs from rabbit placenta using a previously described methodology and to measure their concentrations as well as those of MMP-2 and MMP-9 in the plasma throughout pregnancy. In the course of the work, we noted certain modifications of the biochemical parameters in plasma during gestation, essentially in glycemia and lipemia. We detected proteins immunologically-related to PAGs in placental extracts between D-14 to D-21. Until now, it has been impossible to develop a homologous RIA in order to measure PAGs in rabbit plasma, as the recovery of PAGs during the purification procedure was very low and PAGs were undetectable in rabbit plasma using heterologous RIAs. Finally, we demonstrated a rise in MMP-2 and -9 at the middle and the end of the gestation. However, the small variations presented by these matrix metalloproteinases preclude the use of plasma levels of these enzymes as early markers of pregnancy progress in the rabbit. [less ▲]

Objectif Le présent travail vise à argumenter la pertinence des systèmes de santé de district pour la mise en place de services de santé locaux permettant la prise en charge des principaux problèmes de santé dans un contexte de crise. Matériel et méthodes En Afrique centrale, plusieurs faisceaux d'arguments convergents ont été développés à travers des études sur la performance de districts sanitaires dans trois contextes différents : (1) le suivi sur 17 ans des performances d'un district sanitaire de l'Est de la République démocratique du Congo (1985-2001), (2) l'analyse des performances dans 46 districts de santé dans la partie ouest de la République démocratique du Congo (2003-2004) et (3) l'analyse des performances des districts sanitaires comme pierre angulaire de la réforme sanitaire au Rwanda après la guerre et le génocide (1995-2001). Résultats Dans ces trois contextes, il est apparu que les districts de santé lorsqu'ils disposent d'un minimum de ressources en termes humains et financiers, sont capables de développer assez rapidement des niveaux de performances pour les activités de base et de référence (curatives, préventives, générales ou spécialisées) . Ces derniers sont comparables à ceux que l'on trouve dans la littérature internationale pour des pays de niveau analogue. En outre, les principes d'organisation des districts, notamment à travers les organes de participation, permettent d'envisager le rôle potentiel que les professionnels de santé peuvent jouer dans l'élaboration des processus de paix. Discussion Les différentes causes et facteurs expliquant ces observations positives sont analysés. Parmi ceux-ci, la volonté politique et la capacité humaine apparaissent comme essentielles. En conclusion, nous avons pu étayer l'hypothèse de départ et confirmer le rôle potentiel majeur que peuvent jouer les districts de santé dans le paysage actuel de la santé publique internationale, y compris en situation critique.

The rabbit is an essential model in scientific research, particularly in the study of cardiovascular diseases such as hypertension and atherosclerosis and for the investigation of the osteoarticular system. Due to the fact that various factors (environmental, microbial, stress, pain.) can influence data obtained from experiments, special care must be given to housing conditions. Sensory enrichment (olfactive, auditive, visual or tactile stimuli) and physical enrichment (nutritional and social stimuli) allow rabbits to express specific behaviours and reduce stereotypies. This synthesis reminds of the importance of these factors and gives to the researcher some ways to control them. [less ▲]
