This paper is presenting the results of the interviews of PE teachers and principals involved in an experiment consisting in doubling the number of weekly PE lessons in 10 Wallonian primary schools. Authors used an original approach to “reconstruct” an imaginary interview combining the answers of all subjects. The paper emphasized that practitioners’ views should be heeded when implementing a new programme. The practitioners pointed out that they need mainly to be encouraged when they have good ideas. If specific human resources and facilities’ availability were identified as determining factors, it seems that the main condition of success lies on the real wish of a teaching staff to put the physical activity in the centre of the educational mission of its school. It implies the leadership of the principal, the involvement of the PE teachers and the collaboration of each classroom teacher. A national programme imposed will not have a greater effectiveness than shared positive experiences intelligently highlighted by a marketing action if results of action research would bring objective support helping to convince those who prefer the security of the tradition to any calling into question and additional work.

Background Mercury is known to bioaccumulate and to magnify in marine mammals, which is a cause of great concern in terms of their general health. In particular, the immune system is known to be susceptible to long-term mercury exposure. The aims of the present study were (1) to determine the mercury level in the blood of free-ranging harbour seals from the North Sea and (2) to examine the link between methylmercury in vitro exposure and immune functions using seal and human mitogen-stimulated peripheral blood mononuclear cells (T-lymphocytes). Methods Total mercury was analysed in the blood of 22 harbour seals. Peripheral blood mononuclear cells were isolated from seals (n = 11) and from humans (n = 9). Stimulated lymphocytes of both species were exposed to functional tests (proliferation, metabolic activity, radioactive precursor incorporation) under increasing doses of methylmercury (0.1 to 10 µM). The expression of cytokines (IL-2; IL-4 and TGF-beta was investigated in seal lymphocytes by RT-PCR and by real time quantitative PCR (n = 5) at methylmercury concentrations of 0.2 and 1 µM. Finally, proteomics analysis was attempted on human lymphocytes (cytoplasmic fraction) in order to identify biochemical pathways of toxicity at concentration of 1 µM (n = 3). Results The results showed that the number of seal lymphocytes, viability, metabolic activity, DNA and RNA synthesis were reduced in vitro, suggesting deleterious effects of methylmercury concentrations naturally encountered in free-ranging seals. Similar results were found for human lymphocytes. Functional tests showed that a 1 µM concentration was the critical concentration above which lymphocyte activity, proliferation and survival were compromised. The expression of IL-2 and TGF-beta mRNA was weaker in exposed seal lymphocytes compared to control cells (0.2 and 1 µM). Proteomics showed some variation in the protein expression profile (e.g. vimentin). [less ▲]

RhoA plays a significant role in actin stress fibers formation. However, silencing RhoA alone or RhoA and RhoC did not completely suppress the stress fibers suggesting a residual "Rho-like" activity. RhoB, the third member of the Rho subclass, is a shortlived protein barely detectable in basal conditions. In various cell types, the silencing of RhoA induced a strong up-regulation of both total and active RhoB protein levels that were rescued by re-expressing RhoA and related to an enhanced half-life of the protein. The RhoA-dependent regulation of RhoB does not depend on the activity of RhoA but is mediated by its GDP-bound form. The stabilization of RhoB was not dependent on isoprenoid biosynthesis, Rho kinase, extracellular signal-regulated kinase, p38 mitogen-activated kinase, or phosphatidylinositol 3'-OH kinase pathways but required RhoGDIalpha. The forced expression of RhoGDIalpha increased RhoB half-life, whereas its knock-down antagonized the induction of RhoB following RhoA silencing. Moreover, a RhoA mutant (RhoAR68E) unable to bind RhoGDIalpha was significantly less efficient as compared with wild-type RhoA in reversing RhoB up-regulation upon RhoA silencing. These results suggest that, in basal conditions, RhoGDIalpha is rate-limiting and the suppression of RhoA makes it available to stabilize RhoB. Our results highlight RhoGDIalpha-dependent cross-talks that regulate the stability of RhoGTPases. [less ▲]

The current treatment of chronic obstructive pulmonary disease (COPD) patients must comprise, in addition to an optimal pharmacological treatment, a pulmonary rehabilitation, if possible multidisciplinary, and a program of post-rehabilitation in order to maintain the outcomes. Today pulmonary rehabilitation has proved to be effective in improving dyspnoea, exercise capacity and quality of life in COPD patients, and reducing the use of health services and thus the cost. In this article we want to present pulmonary rehabilitation, its indications and results, and the way by which it is held in the CHU of Liege. [less ▲]

Mesothelioma is a rare tumour, particularly aggressive, whose incidence increases because of the massive use of asbestos during the last century. Asbestos remains indeed the principal etiologic agent of this cancer. In the event of mesothelioma it is advisable to seek an exposure, even of short duration, often which dates back to several decades. In certain circumstances compensation can be obtained at the Occupational Diseases Found. The renewed interest with regard to this tumour is supported by the improvement of mesothelioma management, the new imaging techniques, the new treatments and the broad diffusion of information related to the risk of developing this tumour following asbestos inhalation.

We have studied the influence of the stoichiometry on the structural, magnetic, and magneto-optical properties of bismuth iron garnet (Bi3Fe5O12) thin films grown by pulsed laser deposition. Films with different stoichiometries have been obtained by varying the Bi/Fe ratio of the target and the oxygen pressure during deposition. Stoichiometry variations influence the Curie temperature T-C by tuning the (Fe)-O-[Fe] geometry: TC increases when the lattice parameter decreases, contrary to what happens in the case of stoichiometric rare-earth iron garnets. The thermal variation of the magnetization, the Faraday rotation, and the Faraday ellipticity have been analyzed in the frame of the Neel two-sublattice magnetization model giving energies of -48 K (4.1 meV), -29 K (2.5 meV), and 84 K (7.3 meV) for the three magnetic exchange integrals j(aa), j(dd), and j(ad), respectively. Magneto-optical spectroscopy linked to compositional analysis by Rutherford backscattering spectroscopy shows that Bi and/or Fe deficiencies also affect the spectral variation (between 1.77 and 3.1 eV). Our results suggest that bismuth deficiency has an effect on the magneto-optical response of the tetrahedral Fe sublattice, whereas small iron deficiencies affect predominantly the magneto-optical response of the octahedral sublattice.

Sintered, textured and single crystal products of the layered misfit [Bi0.81CaO2](2)[CoO2](1.69) cobaltite have been successfully synthesized and characterized. Based on structure and texture models, the orientation distribution of the hot-forged sample was successfully analysed by neutron diffraction. The results gave a clear description of the fiber texture with c-axes of the plate-like grains aligned parallel to the hot-forging direction. In terms of transport properties, the decrease of the electrical resistivity according to the degree of alignment and crystallinity of the materials evidenced the important role of the texturation and the strong anisotropy existing in these misfit layered cobaltites.
