Mixed monolayers of the surface-active lipopeptide surfactin-C-15 and various lipids differing by their chain length (DMPC, DPPC, DSPC) and polar headgroup (DPPC, DPPE, DPPS) were investigated by atomic force microscopy (AFM) in combination with molecular modeling (Hypermatrix procedure) and surface pressure-area isotherms. In the presence of surfactin, AFM topographic images showed phase separation for each surfactin-phospholipid system except for surfactin-DMPC, which was in good agreement with compression isotherms. On the basis of domain shape and line tension theory, we conclude that the miscibility between surfactin and phospholipids is higher for shorter chain lengths (DMPC > DPPC > DSPC) and that the polar headgroup of phospholipids influences the miscibility of surfactin in the order DPPC > DPPE > DPPS. Molecular modeling data show that mixing surfactin and DPPC has a destabilizing effect on DPPC monolayer while it has a stabilizing effect towards DPPE and DPPS molecular interactions. Our results provide valuable information on the activity mechanism of surfactin and may be useful for the design of surfactin delivery systems. (c) 2007 Elsevier B.V. All rights reserved. [less ▲]

The invasive alien knotweeds, Fallopia spp. (Polygonaceae), are some of the most troublesome invasive species in Europe and North America. Invasive success in Fallopia may be enhanced by multiple hybridization events. We examined the pattern of hybridization and its evolutionary consequences in Belgium with a concerted analysis of ploidy levels (chromosome counts and flow cytometry), morphological variation, and genetic variation (RAPDs). At least four taxa with different ploidy levels were part of the pattern of invasion in Belgium. Hybrid F.3bohemica with various chromosome numbers restored the genotypic diversity that was lacking in the parental species. Hybrid genotypes were mainly assigned to a specific genetic pool and not to a mixture between the genetic pools of the putative parental species as would be expected for hybrids. Parental species and hexaploid hybrids differed significantly for a set of well-defined morphological characters, enabling future researchers to distinguish these taxa. On the basis of our results, the importance of hybridization has probably been underestimated in large parts of the adventive range of alien Fallopia species, pointing to the need for concerted molecular and morphological analyses in the study of the evolutionary consequences of hybridization.

This paper presents the experimental and numerical tests made on the Titanium based alloy Ti6A14V to identify its yield locus and the hardening behaviour. A bi-axial experimental equipment has been used to perform cyclic shear tests, simple shear tests and successive simple shear tests and plane-strain tests. Coupled with classical tensile tests, these tests enable to identify the yield locus and the hardening model. Teodosiu and Hu’s hardening law and isotropic Swift type hardening and kinematic Armstrong Frederick hardening models have been investigated. [less ▲]

The objective of this study is to describe the eating representations and practices among 60 Roman high-school boys and girls through a complex methodology scheme that associates different techniques (word-association network, semi-directive interviews, test on the drawing of eating contexts, eating attitudes scale). As a result, it emerges that there are two differentiated models of relationship – depending on the sex and the socio-professional category the high-school pupils belong to – to eating and body. A protective model, typical among boys, shows an essentially pleasure-based relationship to eating and body. Eating contexts are lived in a conflicting (family) and play (friends) manner. This model seems to be a factor of preservation against eating pathology risks. On the contrary, a model that presents risks of eating disorders, typical among girls, shows a more complex relationship to eating and to body, characterized by normative aspects that girls shall conform to and/or transgress, according to the eating context. In this kind of relationship, the test on the drawing of the family eating context shows, among other things, the absence of any contact with food. [less ▲]

The pathophysiology and the treatment of diseases with clinical presentation so different as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and psoriasis vulgaris have been revolutionized by the discovery of common pro-inflammatory effector mechanisms involving TNF-alpha and by the use of targeted therapies, the anti-TNF-alpha antibodies. In the past 10 years, our experience has helped several hundreds of patients who were treated with novel drugs, years before they became routinely available. In parallel tools of metrology were developped that can now be applied to the routine patient. Lastly, clinical research on these new drugs has also generated derived research works allowing the university hospital to satisfactorilly fullfil its specific missions. [less ▲]

Matrix metalloproteinases (MMPs) have been implicated in numerous tissue-remodeling processes. The finding that mice deficient in collagenase-2 (MMP-8) are more susceptible to develop skin cancer, prompted us to investigate the role of this protease in cutaneous wound healing. We have observed a significant delay in wound closure in MMP8-/- mice and an altered inflammatory response in their wounds, with a delay of neutrophil infiltration during the first days and a persistent inflammation at later time points. These changes were accompanied by alterations in the TGF-beta1 signaling pathway and by an apoptosis defect in MMP8-/- mice. The delay in wound healing observed in MMP8-/- mice was rescued by bone marrow transplantation from wild-type mice. Analysis of other MMPs showed that MMP8-/- mice had a significant increase in the expression of MMP-9, suggesting that both proteases might act coordinately in this process. This possibility was further supported by the novel finding that MMP-8 and MMP-9 form specific complexes in vivo. Taken together, these data indicate that MMP-8 participates in wound repair by contributing to the resolution of inflammation and open the possibility to develop new strategies for treating wound healing defects.
