The Misten peat bog provides a record of atmospheric deposition in the Hautes Fagnes Plateau (East Belgium). A composite 185cm core (W01/01b) was studied for its trace metal content (TM) and its lead isotopic signature. The peat bog accumulation allows following the history of atmospheric TM deposition during the last 2500 years. TM enrichment factors coupled with a continuous decrease in 206Pb/204Pb, 207Pb/204Pb,208Pb/204Pb isotopic ratios from 494-732AD to1969-1977 AD evidence the increasing importance of TM released by anthropogenic activities. The highest concentrations of TM are found near the surface of the bog; at depths from 30 to 19 cm. Historical records of Cu, Zn, As, Sb, and Pb atmospheric flux during the Industrial Revolution and pre-industrial periods were derived. Maximum fluxes (up to 7.3, 89, 2.4, 1.5, and 116 mg.m-2.y-1, respectively) occurred in peat layers dated from 1619-1877AD to 1992-2000AD, reflecting anthropogenic emissions from diverse sources such as mining, coal combustion, and emissions from the use of leaded gasoline. The TM enrichment factors also increased significantly during the Industrial Revolution until a reduction at the end of the 70’S due to the progressive abolition of the leaded gasoline. [less ▲]

Le chapitre parcourt la mesure des sentiments d'identité des wallons depuis 25 ans: les vagues d'enquête de 1988 à 2013 montrent les fluctuations des sentiments d'appartenance wallon, belge et européen en fonction sur le long terme, où apparaît clairement une déception par rapport à l'Europe après une euphorie initiale chez les jeunes, et qui ne se comble pas avec le temps. La donnée structurelle la plus stable est que les identités wallonne et belge sont complémentaires et non concurrentielles: à chaque enquête, cette corrélation est massive. Par contre, le sentiment d'être différent des Flamands a considérablement augmenté entre 2007 et 2013, ainsi que, sur la dernière période, le sentiment d'être différent de tous les "outgroups" qui augmente.

For many years, our laboratory has been interested in thiamine triphosphate (ThTP), a vitamin B1 derivative whose metabolism and physiological role remain unclear. Regarding its production, we have shown that in E. coli and in rat brain mitochondria, ThTP is synthesized from thiamine diphosphate and inorganic phosphate through a chemiosmotic mechanism involving the FoF1- ATP synthase [1, 2]. In mammalian cells, its concentration is maintained at a low level through hydrolysis by a very specific cytosolic 25-kDa thiamine triphosphatase (ThTPase) [3]. In order to gain insight in the role of ThTP and ThTPase in mammalian tissues, we decided to generate a mouse strain invalidated in 25kDa-ThTPase with the hope that these mice will accumulate ThTP in their tissues. We obtained genetically modified embryonic stem (ES) cells from the Knockout Mouse Project (KOMP) repository. In those cells, one of the 25kDa-ThTPase alleles was replaced by a construction containing the lacZ and the neomycin resistance genes. Those ES cells were microinjected in blastocysts and the chimeric blastocysts were injected in a mouse uterus to generate chimerae. However, when we bred those mice with wild type mice, the construction was never transmitted to the pups. To explain this result, we selected those chimerae that presented a sex-reversal. In those mice, all the spermatozoids derive from the injected embryonic stem cells, so that half of the spermatozoids are expected to harbor the construction. However, after qPCR analysis, we observed that the spermatozoids with the construction were outnumbered by a factor of thousand. These results strongly suggest that the 25kDa-ThTPase is required for spermatozoid development. 1. Gangolf, M., Wins, P., Thiry, M., El Moualij, B. & Bettendorff, L. (2010) J. Biol.

The RC2 antibody is frequently used to label mouse radial glial cells in all parts of the nervous system where neuronal migration occurs during embryonic and early postnatal life. The antigen recognized by this antibody still needs to be identified. We have characterized further its localization in vivo, its expression and subcellular localization in vitro, as well as its molecular nature. Histologic investigations of whole mouse embryos reveal an equally intense expression of RC2 immunostaining in radial glial cells in brain and spinal cord and in skeletal muscle. In glial cells cultures, the RC2 antibody recognizes an epitope located on the glial cytoskeleton and identified as an intermediate filament associated protein (IFAP) at the ultrastructural level. RC2 immunostaining in those cells is strongly dependent on the presence of a serum-derived activity. Serum-removal causes a decrease of the staining while adding serum back to the cells induces reexpression of RC2 immunoreactivity. By Western blotting, we find that in intermediate filament (IF) preparations obtained from cultured cerebellar glia, the RC2 antibody recognizes a 295-kDa protein whose expression is also dependent on the presence of serum in culture medium. In developing muscle cells, RC2 immunostaining is observed from the myoblast stage and disappears after complete myotube fusion. Both in vivo and in vitro, staining is first seen as a loose capping around myoblasts nuclei and progressively concentrates into Z-disks in association with the muscle IF protein desmin. The RC2 antibody also recognizes a 295-kDa protein band in muscle tissue protein extracts. Thus, the RC2 antibody recognizes a developmentally regulated cytoskeletal protein that is expressed, like other previously identified IFAPs, by cells of the glial and myogenic lineages and whose expression in vitro seems to be controlled by a signaling mechanism known to modulate astroglial morphology.

A role for the subtypes of CD2 Ig superfamily receptors has been recently demonstrated in eosinophilic inflammation in experimental asthma and atopic asthmatics. We investigated the functions of 2B4 (CD244) molecules in eosinophil adhesion and chemotaxis, and correlated the results to the pathophysiology of allergic rhinitis (AR). Herein, we show that agonistic stimulation of 2B4 by C1.7, the anti-human 2B4 functional grade purified antibody, resulted in significant increase of eosinophils and eosinophil cell line (Eol-1 cells) adhesion to collagen type IV, and random migration. These functions were associated with tyrosine kinase phosphorylation of several protein residues of low molecular weight. Flow cytometry (FACS) experiments demonstrated that Eol-1 cells, normal peripheral blood eosinophils and eosinophils from AR patients, express surface 2B4 molecules. In vitro AR model demonstrated that the CC-chemokine receptor CCR3 stimulation by eotaxin induced significant increase in the expression of surface 2B4 in eosinophils and Eol-1 cells. Immunofluorescence confocal microscopy images showed that eotaxin induces also redistribution of 2B4 molecules towards the pseudopods in eosinophils and Eol-1 cells, changing their shape. Blocking of 2B4 molecules by the corresponding neutralizing antibody inhibited eotaxin induced Eol-1-adhesion, chemotaxis and the cytoskeleton changes. Pretreatment of Eol-1 cells with 1 microM genistein blocked eotaxin-induced Eol-1 adhesion, chemotaxis and 2B4 up-regulated expression. In vivo correlation demonstrated the expression of 2B4 molecules in eosinophils from AR patients to be significantly increased, after nasal provocation challenge. These results identify a novel role for 2B4 molecules in eosinophil functional migratory response and may point to a novel tyrosine kinase-mediated ligation between CCR3 receptor and 2B4 co-receptor in eosinophil chemotaxis. If so, then 2B4 molecules would be a novel target for therapeutic modalities in diseases characterized by eosinophilia such as AR. [less ▲]

Pores are of crucial engineering significance because they allow water and other harmful substances to enter the material. This paper reviews various methods for porosimetry that are applicable to cementitious materials. Methods generally provide information on porosity and pore size distribution, yet pore continuity is required for transport, so should be investigated as well. Modern ways to approach such problems make use of computer facilities. Hence, the cementitious materials are produced in our case by a concurrent algorithm-based dynamic DEM system. Two novel methods that additionally render possible investigation of pore continuity are described in a separate paper on this conference [1] [less ▲]
