Alcelaphine herpesvirus 1 (AlHV-1), carried asymptomatically by wildebeest, causes malignant catarrhal fever (MCF) following cross-species transmission to a variety of susceptible species of the order Artiodactyla. The study of MCF pathogenesis has been impeded by an inability to produce recombinant virus, mainly due to the fact that AlHV-1 becomes attenuated during passage in culture. In this study, these difficulties were overcome by cloning the entire AlHV-1 genome as a stable, infectious and pathogenic bacterial artificial chromosome (BAC). A modified loxP-flanked BAC cassette was inserted in one of the two large non-coding regions of the AlHV-1 genome. This insertion allowed the production of an AlHV-1 BAC clone stably maintained in bacteria and able to regenerate virions when transfected into permissive cells. The loxP-flanked BAC cassette was excised from the genome of reconstituted virions by growing them in permissive cells stably expressing Cre recombinase. Importantly, BAC-derived AlHV-1 virions replicated comparably to the virulent (low-passage) AlHV-1 parental strain and induced MCF in rabbits that was indistinguishable from that of the virulent parental strain. The availability of the AlHV-1 BAC is an important advance for the study of MCF that will allow the identification of viral genes involved in MCF pathogenesis, as well as the production of attenuated recombinant candidate vaccines.

It has been shown previously that some categories of stimuli are more likely to capture attention under condition of inattention compared to others. This is the case of faces and auto-referential material (e.g., the subject’s own name) in the inattentional blindness paradigm (Mack & Rock, 1998). However, stimuli combining these two properties have never been assessed. Yet it could be that the own face, because it is both a face and a self-referential stimulus, is more prone to attract attention compared to other faces. On the contrary, it could be that the identity and the familiarity of faces are not relevant factors because any face attracts attention by itself and all faces are equally distractive. Moreover, most of previous studies have used schematic unrealistic stimuli. Here, we tested these two opposite hypotheses in a first experiment using photographic stimuli and results showed that the own face does not attract attention compared to another highly familiar face or to an unknown face. Nevertheless, it appears that the own face was still better recognized compared to the others. A second experiment was aimed at verifying whether faces attract attention more than other objects with the same realistic photographic stimuli than used in experiment 1. Results confirmed previous findings that faces are more resistant to inattentional blindness than other objects. Our study suggests that a face by itself attracts attention compared to other objects whatever its familiarity or its identity. These results challenge the view that auto-referential material benefits from specific attentional processes. [less ▲]

Among natural factors driving the soil content in metallic trace elements (MTE), the geochemical background is often deemed as a sound base for the detection of contaminations. Numerous studies have shown the difficulties to take into account the multi-dimensionnality of the spatial variability of most soil properties. As far as a detailed soil map is available for Belgium, the relevance of its information was investigated at various spatial scales in the Walloon Region (Southern Belgium), from the plot to the entire region, to evaluate the feasibility of a multi-scale mapping of geochemical background. A database of soil profiles (gathering both agricultural and forest soils) was used to analyse the relationships between the MTE total content (measured after HF-HClO4-HCl dissolution) and other general characteristics such as pH, Total Organic Carbon content (TOC), Particle Size Distribution (PSD), and cationic exchange capacity (CEC). The factors of MTE spatial distribution inside and between solums were investigated through multivariate statistical analysis. The spatial dependence of these factors was then studied over plot, field, farm, county and region scales, and compared to the spatial structures of the soil map parameters. At the solum level, strong relationships between most of the studied MTE were found, as well as between stone charge and fine earth contents. The PSD is the main driving factor of MTE content in non-carbonated soils, whatever the land use. When considering soil associations, such as catenas, the slope redistribution processes must be taken into account. However, the PSD remains the main driving factors and, as the soil map contains information about that property (mainly the textural class and the profile development), a cartography of the geochemical background based on the use of the soil map and pedotransfer functions or regression models appears relevant. At the regional scale, some long-range spatial structures could be identified. These result mainly from the geological structure of the Walloon region, where the lithological zonation is rather clearly marked. The soil map (texture and nature of stone charge) appears relevant at that scale too but does need a generalization process and fails however to differenciate the intra-type soil spatial variability. Some basic processes of integration of point measurements and qualitative information have been explored. They should be further investigated in the future. [less ▲]

L'abondance de matières colorantes sur certains sites d’habitat sans art pariétal indique qu’il existait probablement des utilisations artisanales et domestiques des ces minéraux. L’utilisation de ces matériaux nécessitait l’élaboration de chaînes opératoires de production qu’il a été possible de reconstituer à travers l’étude des matières colorantes provenant des sites solutréens de Combe Saunière (Dordogne), Fressignes (Indre) et Les Maîtreaux (Indre-et-Loire). L'hématite, produisant une poudre rouge, et les oxydes de manganèse, produisant une poudre noire, sont les matières colorantes préférentiellement recherchées par les Solutréens. Il a été possible de mettre en évidence le chauffage des matières colorantes jaune, qui a pour but la production d'hématite. A Combe Saunière et à Fressignes, le contexte ne permet pas de trancher en faveur d’un chauffage volontaire. En revanche, sur le site des Maîtreaux, une aire de 20 m2 environ concentre des matières colorantes qui ont été triées, stockées et transformées par chauffage. Un certain nombre de matières colorantes rouges résultent du chauffage intentionnel et contrôlé des matières colorantes jaunes. De plus, des indices indéniables de réduction en poudre des matières colorantes rouges jonchent cet espace. L’aire de 20 m² définit un véritable atelier de préparation des matières colorantes, inédit à ce jour. Par ailleurs, le statut économique du site et la richesse des ressources de matières colorantes dans l'environnement immédiat du campement sont intimement liés à la nature des restes abandonnés sur les sites. Ainsi, sur le site d’habitat saisonnier de Combe Saunière, les matières colorantes, dont l'environnement immédiat est riche et varié, ont été clairement réduites en poudre et utilisées directement sans trop de transformations. Sur la halte de chasse de Fressignes, les matières colorantes, inexistantes autour du site sont extrêmement rares et ont été exploitées au maximum de leur capacité par réduction en poudre. Sur le site d’atelier de taille du silex des Maîtreaux, les matières colorantes ont été préparées, transformées, triées et stockées. Leur utilisation devait avoir lieu sur un autre gisement.

The role of corticosterone on the hippocampal structure and function is well documented in male rats. More recently research has shown that chronically stressed female rats with elevated corticosterone levels, exhibit significant dendritic alterations in the hippocampus and, paradoxically, enhanced learning and memory performance. Similar changes have been shown with first reproductive experience (primiparity) compared to further reproductive experience (multiparity). We have shown that at the time of weaning, primiparous rats exhibit altered hippocampal morphology (Pawluski and Galea, 2006), decreased hippocampal cell survival (Pawluski and Galea 2006), and improved reference memory performance (Pawluski et al, 2006) compared to multiparous and virgin female rats. Therefore, given the similarities to what has been shown in the chronically stressed virgin female rat, it seems plausible that corticosterone may play an active role in mediating the alterations seen in primiparous rats. The present study aimed to investigate whether there are differences in the level of free circulating corticosterone during late pregnancy and the postpartum period with reproductive experience. Total corticosterone and corticosteroid-binding capacity were assayed from serum in five groups of rats; multiparous, primiparous, pregnant-only, pup-exposed virgins, and nulliparous rats on 6 days (2 days during gestation: days 14 and 19, and 4 days during lactation; days 1, 5, 14, and 21, where applicable). Results show that total corticosterone level on postpartum day 1 was significantly elevated compared to all other days. In addition, primiparous and multiparous rats have significantly lower corticosteroid-binding capacity throughout lactation. This suggests that primiparous and multiparous rats have more free-circulating corticosterone during lactation. Further research is needed to determine the mechanism underlying the changes in hippocampal structure and function with primiparity. [less ▲]

Isomaltooligosaccharides (IMOs) are non-digestible oligosaccharides, considered as prebiotics and therefore aim to selectively feed probiotics indigenous to the human colon. Recent data obtained in human subjects, support the involvement of dietary oligosaccharides in physiological processes in the different intestinal cell type and also outside the gastrointestinal tract (e.g. hormone production, lipid and carbohydrate metabolism). IMOs consists of glucose monomers linked by at least one α-1-6, or in a lower proportion α -1-3 (nigerose family) or α -1-2 (kojibiose family) glucosidic linkages. In our case they are produced enzymatically from corn starch. It results in a very complex mixture with molecules characterized at the same time by their DP value (from 2 to ~20), linkages types (α-1-2, 3 or 6) and the proportion and position of each type of linkage (only α -1-6 or combined types). The challenge of this study was to find a qualitative and quantitative method to characterize the syrups. In a subsequent study, every unidentified peak could be determined by NMR or Mass spectrometry. Three different chromatographic methods have been tested and compared over their selectivity, sensibility, robustness, applicability and their quantitative power. The HPLC-RID (Refractive Index Detector) used with a Prevail Carbohydrate column (Alltech), adapted for carbohydrates with a certain value of DP, appear to be poorly selective due to the obligation of working in isocratic conditions. The HPLC-ELSD (Evaporating Light Scattering Detector) used with the same column gave a very good separation upon the DP as the Prevail accepts a wide range of solvant changing and even a separation of the different DP 2 molecules. The sensibility was also improved due to the stability of the baseline. The quantitative analysis is a bit more awkward due to the relatively limited linear portion of the calibration curve. High-performance Anion Exchange Chromatography coupled with Pulsed Amperometric Detection (HPAEC-PAD) appeared to deserve a special mention, since it provides selective separation and sensitive detection. In fact, this technique is the only chromatographic one to separate with effectiveness homologue molecules having a difference only in their DP (up to high DPs) or linkage types. This is due to the separation mode based on the difference in ionic force of the sugars in alkaline conditions (mainly due to the DP and the structure of the molecule). However, during the detection, the electrochemical behavior of carbohydrates can be affected by molecular weight as well as by structural differences giving rise to different response factors; as a consequence, HPAEC-PAD is not generally considered as suitable for quantitative studies of complex mixtures of oligosaccharides. In this work a methodological approach is presented in order to get a quantitative response through a rigorous methodology for our IMOs. It also opens the way to the theoretical determination of the response factor for the homologue molecules in relation with their structure and DP. [less ▲]

Testosterone (T) influences the volume and cellular characteristics of a variety of steroid-dependent brain nuclei in many vertebrates. In castrated quail, the volume of the sexually dimorphic (males > females) medial preoptic nucleus (POM), a key area in the control of male sexual behavior, is markedly increased by T but previous studies always assessed this effect after a period of 8-14 days and its specific time-course was unknown. We recently found that following treatment with T, the POM volume increases in a time-dependent fashion: a significant increase was already detected after only one day and the response reached it maximum (volume doubling) after 14 days of treatment. This however raised the question of the cellular mechanism underlying such a rapid brain plasticity (increase in cell size, neuropil volume, dendritic branching, extracellular space?). To research whether a change in extra- vs. intra-cellular space could be responsible for the rapid T-induced increase in POM volume, we repeatedly analyzed by in vivo diffusion-weighted magnetic resonance imaging (DW-MRI) the brain of castrated male quail before as well as after 1, 2, 7 and 14 days of T implantation. MRI was performed on a 7T-system (Bruker) using a multislice diffusion weighted-spin echo sequence. Coronal slices with an image resolution of 100*100*500µm³ were obtained covering the whole telencephalon. Images were accurately coregistered allowing voxel-wise paired comparisons of the ADC data between the different time periods. The ADC significantly increased after one day of T treatment (696±16 vs 758±30 µm²/s, p=0.011, N=5) in POM and this effect apparently persisted during the whole experiment. By contrast, T insensitive regions like the nucleus rotundus (586±170 vs 511±26 µm²/s, p-value=0.24) and nucleus mesencephalicus lateralis, pars dorsalis (934±107 vs 911±64 µm²/s, p=0.68) were not affected after the first day nor later in the experiment. These data indicate that T increases the extracellular water volume in POM specifically, either as a result of cell shrinkage or of an increase in the space between cells, and that changes in the ratio of extra- to intra-cellular water mediate, at least in part, the fast plasticity of the POM volume observed after exposure to T.

Approximated genetic correlations between direct longevity and type traits were computed for a sire Holstein population. Data were based on results for type traits (77,965 records) and for direct longevity (74,289 records) from the INTERBULL routine run of November 2005. Most of type traits presented a high relationship with direct longevity (from 0.06 up to 0.29). The strongest positive correlation with longevity was for udder depth (0.29) and the strongest negative correlation was for chest depth (-0.21). According the different results, an animal with a good direct longevity seemed to be smaller and less heavy than an animal with a shorter longevity. [less ▲]

En neuropsychologie de l’enfant, les troubles attentionnels et exécutifs sont rapportés dans un grand nombre de pathologies développementales (autisme, trouble de l’attention avec hyperactivité… ; voir Pennington & Ozonoff, 1996) et de pathologies acquises (par exemple, le traumatisme crânien [TC]). Et pourtant, le neuropsychologue se trouve encore souvent démuni pour l’évaluation clinique et psychométrique des fonctions attentionnelles et exécutives chez l’enfant. Les quelques épreuves disponibles sont pour la plupart issues de la neuropsychologie de l’adulte et sont de ce fait peu adaptées à l’enfant. Outre le manque d’attractivité qui les caractérise, ces épreuves sont souvent peu pertinentes dans une perspective développementale, en particulier parce qu’elles ne peuvent être administrées que si l’enfant a déjà acquis, au préalable, certaines habiletés cognitives (par exemple, la lecture pour l’épreuve du Stroop ou la connaissance de la chaîne alphabétique pour le Trail Making Test). L’objectif du présent travail consiste à développer une batterie d’évaluation du fonctionnement attentionnel et exécutif (BREFA) adaptée à l’enfant et qui prend en considération les écueils théoriques et cliniques évoqués ci-dessus. Basée sur le modèle de Posner et Petersen (1990), cette batterie a été administrée à 109 enfants âgés de 5 à 11 ans sans antécédents neurologiques. Les épreuves incluses dans la batterie se veulent attractives pour l’enfant (stimuli colorés et familiers) et permettent d’évaluer les capacités d’attention sélective, d’attention soutenue, de flexibilité et d’inhibition cognitive. Des analyses de variance ont été réalisées pour chaque épreuve, avec le groupe d’âge (5 ans - 6 ans - 7 ans - 8 ans - 9 ans - 10 ans - 11 ans) comme variable indépendante. Outre un effet développemental pour l’ensemble des épreuves administrées (p < .001), les analyses post-hoc montrent une amélioration des performances particulièrement marquée pour la tranche 5-8 ans aux épreuves d’inhibition et de flexibilité (p < .05), résultat compatible avec les données issues la littérature (Klenberg, Korkman, & Lahti-Nuutila, 2001). Par ailleurs, des données préliminaires obtenues auprès d’un groupe de 10 enfants atteints d’un TC léger suggèrent que les épreuves de flexibilité et d’inhibition proposées dans la BREFA sont sensibles aux difficultés attentionnelles et exécutives que peuvent présenter ces enfants.

Nous proposons une méthode permettant d’étudier le mouvement des structures osseuses du complexe de l'épaule (humérus, omoplate, clavicule). Cette méthode est basée sur le suivi de nappes de marqueurs plutôt qu'un ensemble de marqueurs individuels à l'aide d'un système de caméras VICON. Le suivi du mouvement des nappes par un algorithme de recalage robuste doit permettre de s'affranchir du mouvement de la peau et avoir accès aux mouvements des structures osseuses sous-jacentes. Cette méthode est comparée à une méthode standard de la littérature. Les résultats montrent que le mouvement de l’omoplate est sous estimé ou sur estimé suivant les axes de rotation. [less ▲]
