La problématique récurrente, c'est la manque d'activité physique chez les jeunes. Une réflexion s'impose en collaboration avec les décideurs politiques, les responsables du sport et de l'éducation pour favoriser un style de vie plus actif et ainsi démontrer que l'activité physique, dont fait partie le sport, et la santé sont intimement liés. L'exposé est divisé en deux parties: (1) Jeu de questions/réponses avec quatre témoins privilégiés ayant tous plus de ving années d'expérience et qui travaillent dans des contextes très différents (niveau d'enseignement, réseau, types de populations différentes, quartiers populaires, écoles à discrimination positive); (2) Court exposé plus théorique.

The new ruralism is both a new concept developed by researchers, especially in California, and a marketing stuff improved by the new vision of the rurality by a broad segment of the American population. The new ruralism results from the conjunction of the smart growth trend and the researches on sustainable agriculture. The paper comments the state of the art and the first projects based on new ruralism. It scrutinizes the impact on the countryside and challenges the contemporary rural geography. [less ▲]

Galectin-3, a multifunctional lectin, is involved during cancer progression. Previous observations showed that both cytosolic expression and nuclear exclusion of galectin-3 in human prostate cancer cells were associated to progression of the disease. In this study, we examined the biological roles of galectin-3 when expressed either in the nucleus or in the cytosol. LNCaP, a galectin-3-negative human prostate cancer cell line, was used to generate transfectants expressing galectin-3 either in the nucleus or in the cytosol. No changes in cell morphology, proliferation, attachment to laminin-1 or androgen dependency were observed. Cytoplasmic galectin-3 induced significantly increased Matrigel invasion, anchorage-independent growth and in vivo tumor growth and angiogenesis, and decreased inducible apoptosis. Surprisingly, nuclear galectin-3 affected these parameters in an opposite fashion with an overall antitumoral activity. Thus, our study demonstrates that galectin-3 exerts opposite biological activities according to its cellular localization: nuclear galectin-3 plays antitumor functions and cytoplasmic galectin-3 promotes tumor progression.

The catalytic activity of five ruthenium-arene complexes of the RuCl2(p-cymene)L type was investigated in controlled radical reactions and olefin metathesis. The ligands L were stable Nheterocyclic carbenes (NHCs) derived from imidazol-2-ylidene. They differed by the nature of the substituents on the nitrogen atoms (R1) and on the carbon-carbon double bond (R2) of the heterocyclic ring. Thus, R1 was either the mesityl or the cyclohexyl group, and R2 included methyl, hydrogen, or chloro substituents.The complexes were tested as initiators for the Atom Transfer Radical Addition (ATRA) of carbon tetrachloride to methyl methacrylate and styrene, for the Atom Transfer Radical Polymerization (ATRP) of methyl methacrylate and styrene, and for the Ring-Opening Metathesis Polymerization (ROMP) of cyclooctene. Some species displayed a dual activity and promoted both olefin metathesis and ATRP. [less ▲]

This paper presents the application of the dual analysis concept to plate bending. In this method, a same problem is analyzed parallely by a displacement and an equilibrium model. The energetic distance between these two models is the sum of both global errors and consequently, an upper bound of each of them. After an exposition of the two models, numerical examples are presented, which illustrate the high obtainable accuracy of the method. [less ▲]

The dual analysis concept was introduced by Fraeijs de Veubeke [1] as a consequence of upper and lower bounds of the energy. As such bounds exist only in those cases where one type of condition is homogeneous, it is commonly admitted that a dual error measure does not exist with general boundary conditions. This paper presents a re-examination of the dual error measure by a way which avoids any use of upper and lower bounds of the energy. It is found that such an error measure holds whatever the boundary conditions be. Furthermore, it is not necessary to obtain the approximate solutions by a Rayleigh-Ritz process, so that the second analysis, which seemed necessary in the original dual analysis concept, may be replaced by any admissible approximation. This implies the possibility of a dual error measure at a simple post-processor level. [less ▲]

We developed dual paclitaxel (PTX)/superparamagnetic iron oxide (SPIO)-loaded PLGA-based nanoparticles for a theranostic purpose. Nanoparticles presented a spherical morphology and a size of 240 nm. The PTX and iron loading were 1.84 ± 0.4 and 10.4 ± 1.93 mg/100 mg respectively. Relaxometry studies and phantom MRI demonstrated their efficacy as T2 contrast agent. Significant cellular uptake by CT26 cells of nanoparticles was shown by Prussian blue staining and fluorescent microscopy. While SPIO did not show any toxicity in CT-26 cells, PTX-loaded nanoparticles had a cytotoxic activity. PTX-loaded nanoparticle (5 mg/kg) with or without co-encapulated SPIO induced in vivo a regrowth delay of CT26 tumors. Together these multifunctional nanoparticles may be considered as future nanomedicine for simultaneous molecular imaging, drug delivery and real-time monitoring of therapeutic response. [less ▲]

In this paper we present an approach for the computation of coupled electromechanical problems in micro-electromechanical systems based on a vector potential formulation of the electrostatic problem. This formulation is the dual of the scalar potential approach commonly used in the literature. We present an analytic derivation of the force computed using this dual method based on the virtual work principle, and compare the primal and dual approaches on the finite element solution of simple twodimensional test-cases.

To prevent numerical instabilities associated with the mesh-dependence, checkerboards and grey regions in topology optimization, a variant perimeter-constrained version of the SIMP algorithm is proposed using a smooth and quadratic function. In order to have an efficient implementation and to make sure the strict satisfaction of such an upper-bound perimeter constraint, a diagonal quadratic approximation of the perimeter constraint is used in the construction of each explicit optimization subproblem. The latter is then solved by a dual sub-iteration scheme. Numerical results show that the incorporation of such a sub-iteration scheme leads to a convergent solution without needs of move-limits or artificial control parameters. In addition to this, it is found that successive relaxations of the perimeter constraint by increasing the upper-bound tend to regularize the topology solution and result in a checkerboard free and satisfactory design solution without grey regions.
