La République populaire de Chine (Chine) est aujourd’hui devenue un partenaire commercial incontournable, un important pourvoyeur d’investissements directs étrangers et un grand fournisseur de prêts financiers pour un nombre croissant de pays d’Amérique du Sud. Cette tendance s’observe également de plus en plus en Amérique centrale. L’accroissement de ses échanges économiques et commerciaux avec le Costa Rica, membre du Système d’intégration centraméricain (SICA) et premier pays centraméricain à avoir signé un accord de libre-échange avec Pékin, va de pair avec l’imposition des normes économiques et politiques dont sa politique commerciale internationale est porteuse. Ce constat pose dès lors la question du défi stratégique que représente cette influence normative chinoise pour les normes exportées par l’UE en Amérique centrale. Afin de répondre à cette question, cette communication se propose d’analyser la portée normative de la politique commerciale de la Chine envers l’Amérique centrale, afin de voir si elle est porteuse d’un projet politico-économique régional comparable au modèle d’intégration et de gouvernance régionale déployé par l’Europe communautaire dans le sous-continent.

Shape-memory polymers (SMPs) are remarkable materials able to switch from a temporary shape to their initial permanent shape by crossing a thermal transition, e.g. glass or melting transition. Efficient shape-memory effect is notably observed for chemically cross- linked semi-crystalline polymers. Chemical networks of semi-crystalline poly(ε-caprolactone) (PCL) are widely studied for the development of SMPs especially when biomedical applications are foreseen. As these SMPs are irreversibly cross-linked material, their (re)processing is quite limited since they cannot be molten or solubilized after cross-linking. This prevents any recycling. Thereby, using reversible cross-linking reactions allowing the formation or cleavage of the network upon a selected stimulus raise tremendous interest for the development of smart SMPs. Chemically cross-linked but remarkably (re)processable shape-memory polymers (SMP) were designed by crosslinking poly(ε-caprolactone) (PCL) stars via reversible cycloaddition reactions. The thermo-reversible Diels-Alder (DA) reaction between furan and maleimide was investigated to crosslink the PCL matrix. However, the relatively low retro DA temperature of the furan-maleimide adducts led to some inelastic deformation during shape memory tensile cycles. In order to get rid of this drawback, two alternative approaches were investigated, i.e. the substitution of the DA reaction firstly by the efficient triazolinedione click chemistry, especially the very fast and reversible Alder-ene reaction of 1,2,4-triazoline-3,5- dione (TAD) with indole compounds and secondly by a photo-reversible reaction, typically the photo-induced (2+2) cycloaddition of coumarins. With these networks, the typical shape memory properties of PCL networks (high fixity and recovery ratios) were preserved while upon an external (light or stress) stimulus, the PCL network can be (re)processed efficiently.

Androgen deprivation therapy is commonly employed for the treatment of nonmetastatic prostate cancer as primary or adjuvant treatment. The skeleton is greatly compromised in men with prostate cancer during androgen deprivation therapy because of the lack of androgens and estrogens, which are trophic factors for bone. Men receiving androgen deprivation therapy sustain variable degrees of bone loss with an increased risk of fragility fractures. Several bone antiresorptive agents have been tested in randomized controlled trials in these patients. Oral bisphosphonates, such as alendronate and risedronate, and intravenous bisphosphonates, such as pamidronate and zoledronic acid, have been shown to increase bone density and decrease the risk of fractures in men receiving androgen deprivation therapy. Denosumab, a fully monoclonal antibody that inhibits osteoclastic-mediated bone resorption, is also effective in increasing bone mineral density and reducing fracture rates in these patients. The assessment of fracture risk, T-score and/or the evaluation of prévalent fragility fractures are mandatory for the selection of patients who will benefit from antiresorptive therapy. In the future, new agents modulating bone turnover and skeletal muscle metabolism will be available for testing in these subjects. [less ▲]

Loin de présenter un visage uniforme, la critique s’exprimant dans les revues d’architecture de l’entre-deux-guerres répond à des enjeux multiples et repose sur diverses postures qui peuvent être publicitaires, doctrinaires ou corporatistes. Sur base de cette classification, cette communication propose d’analyser La Technique des travaux (1925-1940), L’Équerre (1928-1939) et Le Rez-de-chaussée (1928), trois revues dont la naissance est située à Liège, ville belge de seconde importance. En les caractérisant à la lumière d’organes similaires à portée nationale, elle entend montrer la diversité des profils de ceux qui se sont engagés dans la critique architecturale. Car tous les critiques ne sont pas architectes, loin de là. [less ▲]

La polémique apparue autour du film Django Unchained de Quentin Tarantino (2012) permet d’approcher la question de la représentation du stigmate. Mon étude portant sur cette polémique et sur les arguments y étant mobilisés a montré que c’est la représentation d’éléments issus de la culture afro-américaine, ayant participé à la construction d’une identité pour les individus porteurs d’un stigmate ethnique, qui est particulièrement mise en cause. La polémique devient dès lors le lieu d’une resignification des attributs liés au stigmate et d’une réaffirmation de la culture de résistance élaborée autour de celui-ci par ceux qui en sont porteurs. Le terme Nigger et sa présence excessive dans le film ont notamment été relevés par de nombreux internautes. C’est dans ce cadre que nous approcherons la question toujours centrale de l’interpellation stigmatisante, en tant qu’elle semble à la fois devenir le lieu d’une réaffirmation identitaire et permettre l’émergence d’une « réponse habilitante » (Butler, 2008).

Dopamine (DA) neurons of the substantia nigra pars compacta (SNc) exhibit two main firing modes, spontaneous single action potential (AP) firing and bursting. The amount of DA released by these neurons in target areas depends on the presynaptic AP firing pattern and is essential to modulate several aspects of behavior such as the control of movement. Bursting activity is mediated by excitatory afferents and specifically by the activation of NMDA receptors (NMDARs). However, the level of activation of NMDARs at these synapses during spontaneous synaptic activity is unknown. We assessed the occupancy of the glycine binding sites of the NMDAR by testing the effects of coagonists and by blocking the uptake of glycine on spontaneous excitatory postsynaptic currents (sEPSCs) in DA neurons of the SNc. Parasagittal midbrain slices (300 – 350 µm thickness) were cut from the brains 16- to 26- days old Wistar rats using a vibratome. Whole-cell recordings were made using warm (~35C°) standard artificial cerebrospinal fluid. sEPSCs were pharmacologically isolated and recorded at +40 and -70 mV. A large NMDAR-sEPSC component was present at +40 mV as revealed by the application of 50 µM D-AP5 (n=8, P < 0.001). At -70 mV, D-AP5 had no effect on the EPSC, as expected (n=7, P = 0.52). The mean amplitude of the average NMDAR sEPSC measured at +40 mV increased significantly from 8.6 ± 0.8 pA in control conditions to 10.9 ± 1.0 pA during bath application of 300 μM glycine (n=10, P < 0.001). We also investigated the effect of D-serine, the other coagonist at the NMDAR glycine site. The mean NMDAR EPSC amplitude measured at +40 mV showed a tendency toward larger values, from 6.8 ± 0.8 pA in control conditions to 8.8 ± 1.1 pA in the presence of 100 µM D-serine (n=4). Blockade of the glycine transporter-1 (GlyT1) significantly increased the mean amplitude of NMDAR sEPSCs measured at +40 mV from 7.1 ± 0.5 pA in control conditions to 10.5 ± 0.8 pA in the presence of 5 μM NFPS (n=8, P < 0.001). At -70 mV, NFPS had no effect on the AMPAR-sEPSC component, as expected (n=8, P = 0.23). In conclusion, our results indicate that the NMDAR glycine sites are not saturated by glycine and D-serine during sEPSCs in control conditions. [less ▲]
