Aspects relating to the environment, and more particularly climate change, are increasingly holding the stage when it comes to the way the media processes information. Of course, the link between climate change and winters without snow, so-called exceptional flooding, devastating hurricanes or summer heatwaves is perfect material for the headlines of dailies and weeklies. But, what’s more, the concept of global warming is systematically in the headlines because it has become a major stake for society, the environment and the economy. Thus, the written press is calling upon its readers to be conscious of this problem but also to play an active role in this domain. Subsequently, the press tends to call upon us – to its credit – in relation to “good practices” to stop us from wasting energy, and proposes alternatives, which, in general, are not very restrictive. Often, the choice of a “clean” car appears to be an alternative. But compared with the car industry, is the written press coherent with what it puts on paper and the actions it promotes through the adverts it authorises for publication? Therefore, the objective of this paper is to provide an answer to the following three questions: 1] What is the position of car advertising in the written press? 2] What level of emissions are promoted in this advertising in relation to the objectives to be achieved? 3] What could be the solutions to this problem? A detailed analysis of car advertising was carried out in 2006 in four bodies of the Belgian French-speaking written press. The results of this study show that advertising boasts of cars which, in terms of CO2 emissions per kilometre, are from another age, and clearly contradict the values recommended in the in-depth articles written by the journalists of this type of media.

The "red crinoïdal marble" of Baelen represents a local member of the Souverain-Pré Formation (Middle Famennian). At this stratigraphial level, this carbonate mud-mound complex is rather unique worldwide and its occurrence has been related to block-faulting sedimentary conditions. In comparison with similar Frasnian reefs, stromatoporoids, colonial rugose corals and tabulate are absent. [less ▲]

De nombreux auteurs [l , 2, 3, 4] ont montré l'existence d'une activité inhibitrice plasmatique de la Na-K ATPase de type digoxine chez les patients urémiques ou hypertendus essentiels, principalement à activité rénine basse. Cette activité tend à disparaître lors de la déplétion sodée, suggérant que la variation de la balance hydrosodée est un des mécanismes de régulation de la sécrétion de ce ou ces facteur(s) plasmatique(s). Notre étude a été conçue dans le but de vérifier l'existence de cette activité chez des normotendus sains et de rechercher son rôle exact dans la régulation de la balance sodée et son influence sur la paroi vasculaire.

Enteropathogenic and enterohaemorrhagic Escherichia coli (EPEC and EHEC) infections are characterised by the formation of attaching and effacing lesions on intestinal epithelial cells. The first step of EPEC and EHEC pathogenesis involves the initial adherence of the bacterium to the intestinal epithelium. A collection of bovine EPEC and EHEC strains belonging to different serogroups was tested by colony blot hybridization with gene probes for putative adhesins (BFPA, LPFA, IHA, LIFA) of human EPEC and EHEC, and also for fimbrial and afimbrial adhesins (AFA8, F17, Cs31A) of bovine necrotoxigenic E. coli (NTEC). In the bovine EPEC and EHEC strains tested, sequences homologous to lifA, ihA, and lpfA genes were detected, sometimes in association with particular serogroups. Bovine O26 EPEC also possessed a sequence homologous to a gene of the clp operon, coding for the CS31A adhesin, associated with bovine NTEC. Overall results showed that different genes encoding for putative adhesins of human EHEC strains are present in bovine EPEC and EHEC strains, but not one of them is present in all strains. [less ▲]

Using serial sections of frozen and AFA-fixed tissues from 34 breast cancers, we studied the presence of basement membrane material in the areas of elastosis. Various amounts of type IV collagen but not of laminin were demonstrated in areas of periductal elastosis. In some tumors, type IV collagen accumulated beneath the basement membrane. Periductal elastosis in areas of extensive fibrosis showed focal type IV collagen immunoreactivity, indicating remnants of ducts. Interstitial elastosis corresponded with weak type IV collagen reactivity. Each tumor showed type IV collagen immunostaining of the elastotic areas, with various degrees of intensity. Negative crossreactivity of the type IV collagen antibody with elastin was verified in skin biopsies with solar elastosis. Pre-incubation of the antibody with large amounts of elastin demonstrated an identical immunoreactivity. The specificity of the antibody was confirmed by ELISA and by Western blot analysis. To explain the periductal elastosis, we propose the following hypothesis. Excessive production of basement membrane material by the epithelial cells of the ducts leads to formation of a type IV collagen skeleton. This skeleton can act as the matrix for a secondary deposition of elastic material. [less ▲]

Sex differences in song behavior and in the neural system controlling song in songbirds are well documented but relatively little is known about sex differences in hearing. We recently demonstrated the existence of sex differences in auditory brainstem responses in a songbird species, the zebra finch (Taeniopygia guttata). Many sex differences are regulated by sex steroid hormone action either during ontogeny or in adulthood. As a first step to test the possible implication of sex steroids in the control of sex differences in the zebra finch auditory system, we evaluated via immunocytochemistry whether estrogens are produced and act in the zebra finch inner ear. Specifically we examined the distribution of aromatase, the enzyme converting testosterone into an estrogen, and of estrogen receptors of the alpha subtype (ERalpha) in adult zebra finch inner ears. The anatomy of the basilar papillae was visualized by fluorescein-phalloidin, which delineated the actin structure of hair cells and supporting cells at their apical surface. Whole mount preparations of basilar papillae stained by immunocytochemistry revealed in both males and females an abundant aromatase distribution in the cytoplasm of hair cells, while ERalpha was identified in the nuclei of hair cells and of underlying supporting cells. Double labeled preparations confirmed the extensive co-localization of aromatase and ERalpha in the vast majority of the hair cells. These results are consistent with studies on non-avian species, suggesting a role for estrogens in auditory function. These findings are also consistent with the notion that estrogens may contribute to a sex difference in hearing. To our knowledge, this is the first demonstration of the presence of aromatase and of the co-localization of aromatase and ERalpha in the sensory epithelium of the inner ear in any animal model.

After a short winter break, bluetongue virus serotype 8 was responsible in 2007 for a large-scale epidemic among ruminant populations in Western Europe. Little is known about the mechanisms allowing the virus to survive winter conditions. A yearly mass vaccination of cattle and sheep started in spring 2008, which was recognized as successful in terms of clinical protection, but occult circulation of the bluetongue virus has not been adequately addressed. We studied the carriage of bluetongue RNA in the spleen of cattle in the vector-free period and the circulation of bluetongue virus in cattle populations in Belgium since the introduction of vaccination programmes. Overall, the results presented here show evidence for the long-term carriage of bluetongue virus RNA in the spleen of cattle and demonstrated a low but significant circulation and transplacental transmission of bluetongue virus in Belgian cattle in 2009, with apparent disappearance in 2010.

The objective of this study was to evaluate the presence of Clostridium difficile in intestinal and carcass samples collected from pigs and cattle at a single slaughterhouse. C. difficile was isolated in 1% and 9.9% of the pig and cattle intestinal contents and in 7.9% and 7% of cattle and pig carcass samples respectively. A total of 19 different PCR-ribotypes were identified, among them types 078 and 014. Seven of 19 ribotypes correlated with the PCR-ribotypes involved in human C. difficile infections in Belgium. This study confirms that animals are carriers of C. difficile at slaughter and ribotypes are identical than those in humans, and that carcass contamination occurs inside the slaughterhouse. [less ▲]

To characterize ab and gd TcR expression in cultured TILs from a metastatic osteogenic sar- coma.Patient and methods: TILs were isolated from a lung metastasis of an osteogenic sarcoma in a 16- year-old female patient. Culture conditions were IL- 2 and anti-CD3 MoAb+IL-2. TcR expression and surface phenotype were studied by flow cytometry. 4h-chromium release assays were used to assess cytotoxicity. Results:IL-2-expanded tumor infiltrating T-lym- phocytes contained 50% gd TcR+ cells whereas gd TcR+ cells represented 20% of T-cells in cultures expanded with anti-CD3 MoAb+IL-2. The phenotype of gd TcR+ cells was CD3+, CD16-, CD4-, CD8-, and CD29+. AnH-CD3 MoAb + IL-2-expanded TILs mediated a significant lysis of thé autologous tumor and of an allogeneic lymphoma and displayed a higher activity against thé NK-sensitive target K562. In cold target experiments, unlabeled autol- ogous tumor cells blocked thé lysis of K562, indicating that MHC-unrestricted effectors were involved in thé lysis of both targets. Conclusions: This report demonstrates thé ex- pansion of large numbers of gd TcR+ T-cells after short-term culture of TILs from a metastatic os- teosarcoma. Further studies are needed to déter- mine thé role of gd TcR+ cells in host immune responses directed against this tumor. [less ▲]
