Les formes d’investissement de l’espace social et territorial de la Belgique par les Congolais, au lendemain de la colonisation, ne correspondent en rien aux catégorisations actuelles de l’immigration. C’est seulement à la fin des années ’80, que l’on pourra parler d’une immigration économique. Or, dès les années ’60, les Congolais commencent à venir en Belgique dans un cadre estudiantin, diplomatique, “touristique” ou commerçant. De façon progressive, un territoire dans la Ville de Bruxelles va être investi par les Congolais, résidents ou en transit, autour de quelques points de concentration. [less ▲]

Si d’aucuns ont relevé, chez Murray Bail, une propension à la géométrisation des espaces textuels, nul n’a souligné la fonction politico-parodique de la ligne droite dans l’oeuvre de cet écrivain australien contemporain. En feignant de souscrire à la culture de la linéarité, ce dernier vise pourtant à la dénoncer et, avec elle, un certain héritage occidental. Cette réflexion prend, à l’occasion, un tour métafictionnel : bien que ses intentions parodiques aient pu le contraindre à emprunter au réalisme traditionnel certains de ses codes narratifs, Bail a longtemps cherché à discréditer ce genre littéraire trop linéaire. Avec Eucalyptus (1998), l’auteur parvient toutefois à transcender la linéarité structurelle apparente de ses premiers romans. Cet article explore les manières dont Bail s’est approprié le réalisme et/ou l’a transgressé pour, en définitive, mieux l’intégrer à la littérature australienne. [less ▲]

It is often described that it is difficult to really discriminate the cause of intrinsic skin aging. The aim of this study was to compare the profiles of expression of senescence-associated genes in biopsies of dermis from young and old human donors. TGF-beta1 was up-regulated in the dermis of old donors as well as the TGF-beta1-regulated genes. The anti-oxidant enzymes Selenium-dependent Glutathione peroxidase and Glutatione S-Transferase Theta 1 were also up-regulated in old dermis as well as Tumor Necrosis Factor Receptor Superfamily 1A. None of these genes had altered expression level in skin fibroblasts embedded in a collagen matrix and exposed to sublethal doses of UVB, suggesting their involvement in intrinsic aging. This study represents a proof-of-concept of larger whole transcriptome studies where all avenues should be used to subtract changes in gene expression due to extrinsic aging from changes potentially due to intrinsic aging.

The regulated expression of ADAMTS2 (a disintegrin and metalloproteinase with thrombospondin motifs), a secreted metalloproteinase involved in the processing of procollagen to collagen, was studied in peripheral blood mononuclear cells (PBMC). Stimulation with glucocorticoids (GC) resulted in a pronounced dose- and time-dependent increase of ADAMTS2 mRNA levels in PBMC. The increase of ADAMTS2 expression was specific for CD14++ monocytes (440-fold) and alveolar macrophages (200-fold), whereas CD3+ (T lymphocytes), phytohemagglutinin-activated CD3+ (T lymphocytes), and CD19+ (B lymphocytes) showed no significant changes in ADAMTS2 mRNA after GC treatment. Treatment of monocyte-derived macrophages (MDM) with GC also resulted in an increase of ADAMTS2 protein in the culture tissue media. Using the GC analog RU486, GC-mediated induction of ADAMTS2 mRNA was blocked, implicating that GC acts specifically via the GC-receptor. In agreement with findings in blood monocytes, cell lines of the monocytic lineage (MM6, THP-1) showed significant GC-induced significant increases in ADAMTS2 mRNA, while in epithelial cells (A549, Calu-3, Colo320, BT-20) and fibroblast (MRC-5, WI-38, and two NHDF-c cell types from adult cheek and upper arm), they showed no or little responsiveness to GC. As macrophages have important functions in immune defense and tissue homeostasis, these findings suggest that GC-mediated specific induction of ADAMTS2 in these cells may play a crucial role in the resolution of inflammation and wound repair.

The competition between two regimes of the nucleation of superconductivity is investigated experimentally and theoretically in a mesoscopic disk-shaped superconductor/ferromagnet hybrid. By changing the magnetic state of a multilayered Co/Pt disk one can reversibly affect the magnetic-field dependence of the critical temperature T(c)(H) of an Al layer. We demonstrate that an enhancement of the magnetic field near the edge of the out-of-plane magnetized disk either stimulates the nucleation of superconductivity at the disk perimeter due to the field compensation effect or prevents it due to edge magnetic barrier (for relatively low parallel to H parallel to values). As a consequence, the presence of such magnetic-field pattern makes it possible to eliminate boundary effects for mesoscopic superconducting samples. Switching from one nucleation regime to another while sweeping H leads to an abrupt change of the slope of the T(c)(H) envelope. [less ▲]

Schizophrenia is accompanied by deficit in autobiographical memories (AM). These impairments are correlated to difficulties in imagining specific events that might happen to them in the future (D’Argembeau, Raffard et Van-der-Linden, 2008). Previous study suggested that the specific autobiographical memory (past and future) may be improved by an AM remediation therapy (Blairy et al., accepted). The aim of the present study was to compare performances from individuals involved in an AM remediation intervention to individuals involved in the cognitive remediation therapy program from Brenner (IPT) (Pomini, Neis, Brenner, Hodel et Roder, 1998). The results showed that the participants tend to recall more specific events after therapies, confounded pass and future events (t(7) = 3.28 ; p = .013). These results would be promising for future research. [less ▲]

La eleccion de la semilla constituye una de las primeras decisiones que ha de adoptar et agricultor cada ano, a la hora de decidir qué variedad debe sembrar y la calidad de semilla a utilizar. En los ultimos cincuenta anos se han producido importantes avances en el mundo de las semillas que han contribuido a la evolucion hacia una agricultura cada vez mas tecnificada, con una reduccion sustancial de la mano de obra, unida a un empleo cada vez mas importante de maquinaria, abonos, fitosanitarios y nuevas variedades.

Dispersion capacity of alien invasive plants is a key feature for understanding invasion processes and risks. Here, we present an experimental study focussing on the seed rain pattern of Senecio inaequidens, an African plant widespread throughout Europe, under common favourable dispersal conditions. One hundred achenes from two Belgian populations underwent a drop time in still air experiment in order to assess linear correlation between several morphological traits and terminal velocity. Variation in morphological traits was measured for 250 additional achenes per population. The trait best correlated to terminal velocity was the square root of the plume loading. We then used this trait to model terminal velocity using a linear regression (r(2) of 79.7%). With this regression and imposing ecological parameters such as wind speed, turbulences and height of release to be representative of favourable dispersal conditions, we established a Gaussian tilted plume model to predict the seed rain pattern of the species. A wind tunnel experiment consequently permitted to validate the model. Under a wind speed of 5 m s(-1) with 2% turbulences along the vertical axis, and height of release of 0.40 m, 99.8% of achenes were dispersed within 100 meters, with a maximum deposition rate at 5.2 m from the parent plant. Uplifted achenes, not forecasted by the model, represent 6.25% of all achenes. [less ▲]

The role of TGF-beta1 in hydrogen peroxide-induced senescence-like morphogenesis has been described. The aim of this work was to investigate whether TGF-beta1-independent changes in protein synthesis are involved in this morphogenesis and to study possible mechanisms occurring earlier than TGF-beta1 overexpression. Among the multiple TGF-beta1-independent changes in protein neosynthesis, followed or not by posttranslational modifications, identified by proteomic analysis herein, those of ezrin, L-caldesmon, and HSP27 were particularly studied. Rho-GTPase cdc42 was shown to be responsible for p38(MAPK) activation, in turn triggering phosphorylation of L-caldesmon and HSP27. Cdc42 was also shown to be mainly responsible for the increase in TGF-beta1 mRNA level observed at 24 h after treatment with H(2)O(2) and onward. This study further clarified the mechanisms of senescence-like morphogenesis in addition to the previously demonstrated role of TGF-beta1 signaling pathways. [less ▲]
