In the wider framework of the search for the alternatives for the preventive use of antobiotics, the present experiments have shown that inulin could interfere in vitro with the adhesion of a pathogenic coliform to the intestinal porcine mucosa. Moreover, a first immunization experiment pointed towards a systemic specific immunomodulation (increase in IgA and IgM titres) by inulin after a boost with intramuscularly injected bovine thyroglobulin (BT).

Cette contribution se penche sur le mode de gouvernance régionale mis en place au travers du Marché commun du sud (Mercosur). En vingt ans d’existence, ce dernier est parvenu à se doter d’une série de stratégies et d’institutions communes. Il se démarque par sa nature multidimensionnelle et partant se veut une forme de laboratoire des modes de coopération dans des domaines aussi variés que l’économie, le commerce, l’enseignement ou le politique. Toutefois, l’intégration régionale est définie et contrôlée principalement par les États qui la composent et la défense des intérêts nationaux se fait souvent au détriment des engagements communautaires occasionnant d’âpres conflits intrarégionaux. Cette situation révèle les grandes difficultés des instances régionales à résoudre sereinement les différends entre États. Enfin, contrairement aux prédictions, le nationalisme économique et radicalisme politique de cette dernière décennie ne favorisent pas la consolidation de l’intégration et la cohésion régionale.

The spaces of tensor densities over a manifold M are modules over the Lie algebra Vect (M) of vector fields over the manifold. When M is a contact manifold, one can consider the algebra C(M) of vector fields which preserves the contact structure. If the manifold is endowed with a contact projective structure, there is an embedding of the linear symplectic algebra sp (2n+2,R) in C(M). In this Letter, we determine the C(M)- and the sp(2n+2,R)-invariant bidifferential operators on tensor densities. [less ▲]

We present a family of invariant games which are variations of Wythoff's game.

Metastases formation is a complex process involving genetic and epigenetic modifications leading to several molecular pathway dysfunctions and alterations in the production and fonction of a panel of molecular mediators. Recent studies have shed light on the importance of multiple interactions occuring between tumor cells and host cells involved in the elaboration of a microenvironment permissive for tumor cell survival and growth. These tumor-host interactions are decisive, not only in the primary tumor, but also in secondary sites colonized by tumor cells. Cancer appears more and more as a sytemic disease in which tumor cell is one of the pawn in the game. System of defense are rapidly overwhelmed and tumor cells hijack host cells to promote their dissemination that likely occurs at earlier stages than initially anticipated. In the present review, we describe the novel concepts of metastases formation based on recent transcriptomic analyses and new insights acquired on the tumor microenvironment in the primary tumor and in secondary foci.

Desmoid tumours are locally invasive soft tissue tumours in which beta-catenin mediated TCF-dependent transcription is activated. The role of soluble factors secreted by the myofibroblastic desmoid tumour, which could stimulate tumour invasiveness, was investigated. Using collagen gel invasion assays, the presence of factors stimulating invasion in desmoid conditioned media (CM) could be established. Since matrix metalloproteinases (MMPs) have been implicated in the process of tumoral invasion, the expression levels of the MMP family members were evaluated. Quantitative reverse transcription-PCR was used to determine the expression levels of MMP1, MMP2, MMP3, MMP7, MMP11, MMP12, MMP13, MMP14 and the inhibitors TIMP1, TIMP2 and TIMP3. Besides overexpression of MMP7, a known TCF-dependent target gene, a striking upregulation of the expression levels of MMP1, MMP3, MMP11, MMP12 and MMP13 in desmoid tumours, compared to unaffected fibroblasts from the same patients, was found. Treating the CM of desmoids with a synthetic and a physiologic MMP inhibitor reduced the invasion-stimulating capacity of the desmoid CM by approximately 50%. These results suggest the involvement of soluble factors, released by the desmoid cells, in stimulating invasion and implicate the MMPs as facilitators of invasion. [less ▲]

Fallopia japonica is one of the most troublesome alien invasive plants across temperate regions, with large negative impacts on plant species diversity. We examined its impacts on topsoil chemistry and nutrient stocks in standing biomass at 6 sites with contrasting resident plant communities in Belgium. Topsoil and biomass were sampled in invaded and closely adjacent uninvaded plots. Standing biomass and mineral nutrient concentrations in soil (ammonium acetate exchangeable cations and P, total C, and N) and plants were determined. Soil under F. japonica generally had higher exchangeable nutrient concentrations (Cu: +45%, K: +34%, Mg: +49%, Mn: +61%, P: +44%, Zn: +75%). Standing biomass was 3- to 13-fold higher depending on site. Despite lower nutrient concentrations in aboveground biomass, invaded stands had 3.2- to 5.4-fold larger nutrient stocks in aboveground biomass compared to the resident vegetation. We conclude that F. japonica enhances nutrient cycling rates and topsoil fertility, probably due to nutrient uplift. The impacts were greatest in sites with low nutrient concentrations in uninvaded plots, suggesting that F. japonica may contribute to soil homogenization in invaded landscapes. [less ▲]

Tumor progression is influenced by extracellular matrices and by soluble factors or cytokines locally produced by host tissue cells (fibroblasts, immune cells ...). Such factors may also accumulate in close association with some extracellular matrix molecules in the tumor. They may also be unmasked during breaking down of extracellular matrices. The most insidious aspect of tumors is their propensity to locally invade normal tissues of the host and to form secondary foci in organs at distant sites from the primary tumor called metastases. During this process, invasive cells come into contact with host tissue cells such as fibroblasts, endothelial cells, macrophages, lymphocytes. These cells are not the passive witnesses of the metastatic cascade but actively participate to the malignant invasion. Through soluble messages (cytokines) and through insoluble molecules of the extracellular matrix, neoplastic and normal cells mutually modulate their activities. Cancer cells regulate the biosynthetic activities of fibroblasts and alter in this way the scaffold of the tumor. Reciprocally, host cells secrete extracellular matrix proteins and cytokines which influence the growth and activities of tumor cells. They also produce at the periphery of tumor cells proteolytic enzymes which promote host tissue destruction and cancerous cells migration. Among these enzymes, matrix metalloproteinases appear to play a key role during invasion and metastasis. Tumors represent thus a complex ecosystem. Tumor cells interact with several components of the extracellular matrix and with host cells (immune cells, fibroblasts, endothelial cells). Such multiple cell-cell and cell-matrix interactions condition angiogenesis, tumor growth, destruction of host tissues, local migration of cancer cells and their metastatic dissemination. It is probable that a precise knowledge of the genes which are selectively activated in tumors under the influence of the host cells or of the tumor cells will allow to define new therapeutic strategies. These treatments will aim not at destroying the metastatic neoplastic cells but at preventing their growth by interfering with their microenvironment. [less ▲]
