Follicular dendritic cells (FDC) are only located within follicles of secondary lymphoid tissues. The origin of this peculiar cell type is not clearly defined. To contribute to this study, we applied two monoclonal antibodies (MAS516 and 5B5) considered as specific for fibroblasts to tonsil cryosections and to isolated follicular dendritic cells. On the basis of an enzyme cocktail digestion of human tonsils and a fractionation procedure on albumin gradients, FDC can be prepared in the form of cell aggregates with associated lymphoid cells. MAS516 reacts with surface membrane molecules expressed by human fibroblasts, tissue macrophages and peripheral blood monocytes. With immunoperoxidase assays on tonsil cryosections connective tissue cells and macrophages are stained. Inside germinal centres, heavy labelling of the light zone was found. The MAS516 staining pattern is very similar to that of specific FDC markers DRC-1 or BU10. All isolated FDC reacted with MAS516 antibody. 5B5, considered as a typical fibroblast marker, reacts with human prolyl-4-hydroxylase which is an intracellular enzyme related to collagen biosynthesis. In cryosections, interfollicular and capsular areas showed 5B5 positive connective tissue fibroblasts. In germinal centres, some cells presenting features of FDC were 5B5 positive. After cell separation, 25%-50% of the isolated FDC were labelled with this antibody. This positivity of some FDC for 5B5 antibody may support the idea of their fibroblastic origin. The combination of observations realized in situ and after cell purification ensured an unequivocal recognition and identification of FDC.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

Abstract We present the development of a speckle interferometer based on CO2 laser and using a thermal infrared camera based on uncooled microbolometer array. It is intended to be used for monitoring deformations as well as flaw detection in aeronautical composites, with a smaller sensitivity to displacement compared to equivalent system using visible lasers. Moreover the long wavelength allows working with such interferometer under out-of-laboratory conditions. A mobile system has been developed on the basis of previous laboratory developments. Then it is validated in a variety of industrial nondestructive testing applications under field working conditions. [less ▲]

Les récits ethnographiques et les réflexions que je vais présenter dans cet article sont issus d’une recherche menée dans les villes marocaines de Khouribga et de Rabat entre 2007 et 2008. L’étude concerne la mobilité d’un groupe de jeunes « khouribgii » inscrits dans des projets migratoires vers l’Italie ainsi que les actions et les discours de certains organismes humanitaires (internationaux et locaux) s’occupant de thématiques liées à la migration. L’utilisation d’une distinction terminologique adoptée ici entre mobilité d’une part et migration d’autre part, a été choisi pour représenter une différenciation opérée entre l’expérience faite de la mobilité par ces jeunes à travers leur préparation à la migration, et le blâme et l’entrave à l’action de migrer opérée dans les discours et par les actions des ONG. D’un côté nous avons donc une mobilité qui s’exerce dans l’imaginaire de ces jeunes, tout comme dans des pratiques concrètes mises en place pour réaliser le projet migratoire (qui comportent l’apprentissage d’instruments utiles à l’affronter, tels que la langue italienne ou la capacité de mouvement à travers l’appareil législatif international et national qui régisse la migration) ; une mobilité qui s’exerce également dans la participation aux réseaux migratoires familiaux ; et de l’autre côté, une migration dissuadée par les programmes humanitaires ou sociaux. Ces derniers consentent une mobilité qui puisse s’accomplir dans un rapprochement « virtuel » au pays de destination, à travers notamment des cours de « culture italienne », mais en détournant la définition des parcours migratoires personnels et en les insérant dans la rhétorique de la « migration intelligente », c’est-à-dire en demandant que, s’ils arrivent à être réalisés, ils soient utiles au « développement » de la communauté locale d’origine. A travers l’analyse de ces aspects, cet article vise donc à démontrer la réalité des déplacements des jeunes interviewés, malgré leur permanence sur le territoire marocain, la concrétisation de leur aspiration de migration dans l’expérience de la mobilité, en remettant donc en cause la frontière entre les deux concepts définis ci-dessus.

Northern elephant seals (NES) (Mirounga angustirostris) from the Año Nuevo State Reserve (CA, USA) were longitudinally sampled during the post-weaning fast in order to study the mobilisation and redistribution of various classes of persistent organic pollutants (POPs), such as polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), dichlorodiphenyldichloroethylene (p,p′-DDE) and hexachlorobenzene (HCB) between blubber and blood. Inner and outer blubber layers were analysed separately. Organohalogenated compounds were detected in all blubber samples in the decreasing order of their concentrations: p,p′-DDE>PCBs⪢HCB>PBDEs. The concentrations of all studied compounds were homogeneously distributed in the blubber layer at early fast, since the concentrations of POPs were statistically not different in the inner and outer layers. With the progression of the fast, the concentrations of PBDEs, PCBs and p,p′-DDE increased more sharply in inner blubber than in outer blubber. As a result, their levels became significantly higher in inner blubber as compared to outer blubber at late fast. The rise of pollutant concentrations in blubber might result from a less efficient mobilisation than triglycerides and/or a reuptake by adipocytes of some of the pollutants released into the circulation. The mobilisation of pollutants from blubber was higher at late fast. An increase of pollutant concentrations was observed in serum between early and late fast. Lower halogenated congeners (i.e. tetra-CBs) were present in higher proportions in serum, whereas the higher halogenated congeners (i.e. hepta-CBs) were mainly found in the inner and outer blubber layers. The transfer ratios of both PBDEs and PCBs from inner blubber to serum decreased with the number of chlorine and bromine atoms. In addition, the distribution of both types of compounds between serum and blubber was strongly influenced by their lipophilic character (log Kow values), with more lipophilic compounds being less efficiently released from blubber to serum.
