Background: Inflammatory airway disease (IAD) affects performance and well-being in horses. Diagnosis is primarily reached by bronchoalveolar lavage (BAL) cytology but this is invasive and requires sedation. Objectives: The purpose of this study was to identify candidate blood biomarkers of IAD using species-specific expression microarrays. Methods: Horse Gene Expression Microarrays were used to investigate global mRNA expression in circulating leukocytes from healthy and IAD-affected standardbreds and endurance horses. Results: Nine genes were significantly differentially regulated in standardbreds and 61 in endurance horses (P < 0.001). These genes were mainly related to inflammation (eg. ALOX15B, PLA2G12B and PENK), oxidant/antioxidant balance (eg. DUOXA2 and GSTO1-1) and stress (eg. V1aR, GRLF1, Homer-2 and MAOB). DUOXA2, ALOX15B, PLA2G12B, MAOB and GRLF1 variations of expression were further validated by RT-qPCR. The deregulation of the oxidant/antioxidant balance was demonstrated at the protein level by an increase of glutathione peroxidase (GPx) activity in heparinised whole blood of IAD-affected standardbreds (P = 0.0025) and endurance horses (P = 0.0028). There was good correlation (r = 0.7354) between BAL neutrophil percentage and whole blood GPx activity in all horses. Conclusions: There is accumulating evidence that, even when systemic clinical signs are not evident, circulating leukocyte gene expression can reflect responses of other tissues, leading to potential diagnostic applications in the future. Although not specific for IAD, whole blood GPx activity appears to reflect BAL neutrophil percentage. This finding should be further assessed by testing a larger number of horses. [less ▲]

With a few exceptions, the emerging field of production studies has dealt mainly with the analysis of Western film industries. This chapter addresses this gap by looking at the growing African digital film production industries in Southern Nigeria and Ethiopia, and by pointing out the specificities of the production cultures that have emerged within this context. By applying an ethnographic approach to the study of film production, this chapter highlights the ambiguous position that digital film production occupies in these two countries between, on the one hand, the creation of new avenues of economic and social mobility, and on the other the emergence of strategies of exclusion and control.

This paper looks at migration and the politics of representation in contemporary Italian cinema by comparing one of the Nigerian videos recently produced in Italy, Akpegi Boys (2009), directed by Vincent Omoigui and Simone Sandretti, with two recent Italian films which portray the experience of Nigerian migrants in Italy, Marco and Antonio Manetti’s Torino Boys (1997), and Enrico Verra’s Sotto il Sole Nero (2004). Interestingly enough both films take, implicitly and explicitly, Nigerian videos as a narrative and aesthetic reference in order to build an innovative representation of Nigerian migrants in Italy, thus positioning themselves in an original position vis-à-vis the growing corpus of Italian films about migration emerged over the past two decades. As this paper argues, these three films allow us to identify the emergence of what could be defined as an “anti-humanitarian” representation of migration. By defining their attitude as anti-humanitarian, I do not intend to mean that these films assume a negative or derogatory perspective on migration. On the contrary, what I intend to highlight is that these are films that, by using a number of specific narrative and aesthetic strategies such as, among others, the reference to Nollywood commercial and exploitation filmmaking style, make an attempt to go beyond the binary representation that much debate on migration in Italy implicitly embraces, a representation according to which the migrant is either seen as an invader or as a victim. By playing with cultural references that belong to the contemporary cultural universe of Nigerian migrants themselves, these films suggest the possibility of building a bridge between the diverging ways in which Italians and (in this case Nigerian) migrants look at migration. This encounter has the potential of helping Italian directors and intellectuals in deconstructing their hegemonic gaze on migrants and migration phenomena, and has the possibility to inaugurate an healthy as much as needed process of decentralization and provincialization of singularly “Italian” perspectives on migration in Italy.

BACKGROUND: Single cell biology has attracted a lot of attention these past few years and has led to numerous fundamental results pointing out the heterogeneity of clonal cell populations. In this context, microbial phenotypic heterogeneity under bioprocessing conditions needs to be further investigated. In this study, yeast based processes have been investigated by using on-line flow cytometry in combination with a fluorescent transcriptional reporter (GFP) and viability fluorescence tags (propidium iodide, PI). Methods aiming at expressing the dispersion of these fluorescence tags among the yeast populations have been investigated for different bioreactor operating conditions. RESULTS: Yeast viability was determined on the basis of PI uptake. Segregation between PI negative and positive subpopulations could be efficiently quantified on the basis of the mean-to-median ratio or the amplitude of the interquartile range. On the other hand, the same quantification could not be made for the segregation occurring at the level of GFP synthesis. Indeed, when cells were exposed to sub-lethal or mild stresses (such as in scale-down reactors) two GFP subpopulations could be visualized by real-time FC, but quantification by one of the above-mentioned methods was not possible. CONCLUSIONS: Yeast population heterogeneity was observed in representative bioreactor operating conditions. Difficulties for the determination of segregation at the level of GFP synthesis point out the fact that one needs to understand the segregation mechanisms for the applied fluorescent reporters, to judge whether simple mathematical tools may be applied or if more sophisticated computational tools are needed for the quantification of the microbial population segregation.

Light pollution is defined as the abnormal and disturbing presence of light and its adverse consequences on flora, faunae, ecosystems and its suspected or proven effects on human health. Light pollution is a quite recent and increasing phenomenon within our society and it leads to a major environmental damage, obviously near wildlife, but also on human health (cancers, obesity, fatigue, depression...). The solutions to this problem are however simple, efficient and de facto inexpensive and involving a substantial energy saving. [less ▲]

The 45th International Liege Colloquium on Ocean Dynamics (http://modb.oce.ulg.ac.be/colloquium/) gathered two hundreds scientists from around the world to discuss new insights related to the evaluation of primary production at various spatial and temporal scales and in different regions of the world ocean (e.g. the polar and sea-ice region, the coastal and the deep ocean). Over the past two decades, substantial efforts were deployed to evaluate oceanic primary production. These efforts include in situ measurements of uptake rates using isotopic techniques, remote sensing, autonomous instrumentation for bio-optics, carbon or oxygen measurements, and the development of semi-empirical to complex biogeochemical models. The colloquium presented the opportunity to review the current knowledge in the estimation of primary production, and to assess the impact of physical processes on ocean productivity. Particular attention focused on the importance of physical processes at different spatial and temporal scales for controlling the level and variability of primary production and on the development of adequate methodologies to tackle this variability in order to derive large-scale, climate-driven budgets. Refined biogeochemical models considering for instance phytoplankton physiology, the representation of variable elemental stoichiometric ratios, the role of mixotrophy as well as satellite algorithms that are now able to simulate the plankton functional types are good candidates for scaling up. Contributions dealing with the difficult issue of interoperability of in-situ, satellite and modelling estimates of primary production were presented. Details on the terms of reference as well as the thematic session that were organized can be found at http://modb.oce.ulg.ac.be/?page=colloquium&year=2013. [less ▲]

Since its creation in 1830, Belgium has experienced tensions between language and politics. The question of the linguistic or community-related nature of these tensions should be raised since they have regularly been referred to as linguistic by some researchers and as community-related by others. But the choice of these adjectives is not unimportant considering they frame the representations of the political issues at hand. The aim of this article is to tackle this question from the combined perspective of linguistics and political science. In the first, the article explores the genealogy of the adjectives ‘linguistic’ and ‘community-related’ as well as the multiplicity of their uses in the scientific literature. In the second part, it focuses on the ways citizens see and talk about Belgian federalism through the respective analyses of their mental representations and their conceptual metaphors. Such interdisciplinary endeavour, bringing together theoretical and empirical insights, seeks to yield a renewed understanding of the political relations in Belgium and to contribute to the debate about plurilingual societies.

La fertilité d’un sol conditionne la productivité des plantes, c’est pourquoi il est intéressant de connaitre la distribution des caractéristiques chimiques et morphologiques du sol afin de permettre une exploitation et une gestion optimales de celui-ci. Un versant forestier, en pente forte (140m de long, 40m de dénivelée), sur matériaux schisto-gréseux et sous une plantation de résineux fait l’objet d’un suivi du fonctionnement hydrodynamique et pédochimique en relation avec le développement des arbres. Au vu du contexte de forte pente, nous suspectons la présence d’apports par solifluction. La position dans le versant est souvent un facteur de différenciation des sols et, en préalable à l’étude de l’évolution temporelle des propriétés des sols et de la végétation et de l’évolution spatiale des flux d’eau, nous nous sommes attachés à la caractérisation de la distribution des propriétés morphologiques et chimiques le long du versant. Huit fosses ont été creusées et échantillonnées selon les horizons. Outre les descriptions selon un protocole standardisé, nous avons effectué des comptages racinaires, des mesures de densité apparente et de charge caillouteuse. Les analyses en laboratoire visent la caractérisation du statut nutritif : pH, teneurs échangeables (NH4Cl) en K, Mg, Na et Ca, et P assimilable (Dyer). Les résultats confirment l’importance de la différenciation verticale au sein des profils. On notera également une légère tendance à la hausse du pH et des teneurs en éléments nutritifs entre le haut et le bas du versant, à l’exception du dernier profil de la séquence. [less ▲]

Cette communication vise à étudier la participation des femmes migrantes marocaines à la vie sociale du « pays d’accueil » ; participation qui se réalise grâce aux activités de la vie quotidienne. En particulier, la performance publique des pratiques culinaires, observée dans une ville de la province de Milan, permet aux femmes considérées d’exercer une agency à l’intérieur des espaces institutionnellement concédés à l’expression des migrants. D’un côté, la consommation des « recettes de l’Autre » de la part de la population majoritaire détermine une incorporation de la diversité afin de la contrôler. De l’autre côté, la préparation de ces recettes consent aux migrantes d’exprimer leur subjectivité (individuelle et collective) de façon active et en présentant des aspects qui vont au-delà de la culture alimentaire. Une participation sociale fondée sur le partage de nourriture donne la possibilité aux femmes d’assumer un rôle actif dans la communauté locale, tout en affirmant ses propres spécificités. Des sujets tels que la liberté religieuse sont abordés, et certains droits peuvent être réclamés par des individus qui ont ainsi acquis une position politiquement importante au sein de la société locale.
