Styrene has been polymerized by a Quinone Transfer Radical Polymerization (QTRP) based on the redox reaction of an ortho-quinone and a metal catalyst. Several metal acetylacetonates have been tested in this work. The radical polymerization of styrene is largely controlled when phenanthrenequinone (PhQ) is used with catalytic amounts of Co(acac)(2), Ni(acac)(2), Mn(acac)2 or 3, and Al(acac)(3). As a rule, in the presence of all these metallic complexes, the polystyrene molar mass increases with the monomer conversion, and polydispersity (M-w/M-n) is in the 1.3-1.6 range (at least until 40% monomer conversion). Styrene polymerization has also been resumed by polystyrene chains prepared by QTRP. In the specific case of manganese acetylacetonates, an amine or phosphine ligand has to be added for the control to be effective. Finally, two mechanistic hypotheses have been proposed, depending on whether the oxidation state of the metal can be easily changed or not. [less ▲]

Several o-quinones have been tested as control agents for the quinone transfer radical polymerization (QTRP) of styrene in the presence of cobalt(II) acetylacetonate. In contrast to the commercially available 3,5-di-tert-butyl-o-benzoquinone (3,5-DtBBQ) and tetrachloro-1,2-benzoquinone (tetrachloro-1,2-BQ), 3,6-dimethoxy-9,10-phenanthrenequinone (3,6-DMPhQ) imparts a better control to the radical polymerization of styrene compared to 9,10-phenanthrenequinone (PhQ) used as a reference. Indeed, whenever 3,6-DMPhQ is added with a catalytic amount of metal complexes (Co(acac)(2) or Al(acac)(3)), the evolution of the molar mass with the monomer conversion is linear, and low polydispersity (M-w/M-n similar to 1.1-1.2) is observed until very high monomer conversion (similar to 90%). Finally, the methoxy protons of 3,6-DMPhQ have been detected by H-1 NMR analysis of the polystyrene end groups, which is important mechanistic information. [less ▲]

ortho-Quinones, such as phenanthrenequinone and 3,6-dimethoxyphenanthrenequinone, added with a catalytic amount of metal complexes, impart control to styrene polymerization via the previously reported quinone transfer radical polymerization (QTRP) process. In this study, compounds that mimic the dormant species proposed in the QTRP mechanism have been synthesized and tested as initiators in the presence of cobalt(II) acetylacetonate. These compounds, and particularly 3,6-dimethoxy-10-hydroxy-10-(l-phenyl-ethyl)-phenanthren-9-one, are effective control agents for the radical polymerization of styrene, in agreement with the recently proposed mechanism. Moreover, the induction period, which has been systematically reported in the presence of ortho-quinones, is no longer observed. The end capping of the polystyrene chains by the control agent has been confirmed by H-1 NMR analysis. [less ▲]

After fifteen years of use, the anti-TNF antibodies have become the corner stone of the treatment of moderate and severe Crohn's disease. The skill acquired over the years through experimental trials and clinical experience leads to increased therapeutic efficacy and minimized risks. These antibodies are introduced increasingly earlier in Crohn's disease as well as in a broader range of patients, aiming at changing the natural history of the diseases by avoiding the development of intestinal tissue damage and complications.

Dans un article de 2002, Jean and John Comarrof se penchent sur les « contradictions expérientielles » de ce qu’ils appellent un « capitalisme millénariste », c’est-à-dire « un capitalisme investi d’une force salvatrice » devant permettre la transformation des marginalisés et des subalternes » (Jean Comaroff and John Comaroff, « Alien-Nation : Zombies, Immigrants, and Millenial Capitalism », The South Atlantic Quarterly, n° 101, 4, Fall 2002). L’étude du fonctionnement du capitalisme flexible en Chine, avec son processus d’accumulation résultant de la combinaison de mécanismes institutionnels hérités du maoïsme et de mécanismes de marché, permet de se pencher sur les ruses du capitalisme, sur les redéploiements de modes complexes de gouvernement et de domination et sur les modes d’accommodement et de résistances des individus et groupes sociaux. Dans cette communication, j’explore des modes de domination qui, en parallèle avec la répression routinière et les régimes de production disciplinaires, agissent de façon complexe parce qu’ils sont basés sur des catégories d’émancipation et qu’ils travaillent au niveau des espoirs individuels de changement de condition, agissant au niveau des catégories de sens commun ou pratiques dans un contexte où le développement des forces productives et du marché constitue un champ idéologique intensément investi par les élites urbaines et l’Etat-parti. En me penchant sur les modalités de mise en récit et de luttes autour de la migration et du travail en ville─ mobilisations stratégiques, accommodements, renversements et chevauchements hégémoniques ─, j’entends montrer comment les expériences et récits des travailleurs migrants chinois s’articulent au sein d’un projet hégémonique de légitimation de l’ordre social et d’extraction de la plus value. Pour appréhender ce processus, je mobiliserai la notion de « cadre hégémonique » (Roseberry) entendu comme projet politique visant à établir un cadre matériel et discursif commun afin de cadrer et d’organiser la colère, la frustration mais aussi les espoirs, les aspirations et les désirs.

Since the 1980s, parliamentary technology assessment (PTA) institutes have emerged across Europe, typically with the aim of advising parliaments about the potential social, economic, and environmental implications of sciences and technologies. While until recently, these institutes appeared to have established themselves as dependable partners for policymakers, PTA is increasingly under threat from funders, as illustrated by the Danish Government’s call to disband the Danish Board of Technology and the Flemish Government’s decision to restructure the Flemish Institute Society and Technology (IST). It is hence uncertain whether these institutes will continue to fulfill their present functions as independent policy advisors and think tanks, and as catalysts for public debate. In this paper, we describe the difficulties Flemish PTA, and the IST in particular, faces today. Drawing on arguments and counterarguments to close down and/or reform the IST, we lay out envisioned futures for PTA in Flanders. From a concern with making PTA more visible and potent as a policymaking instrument, we distinguish four grand challenges PTA practitioners and advocates face: (1) increasing the public visibility of PTA; (2) ensuring the uptake of PTA ideas in science and technology discourses; (3) forging closer ties between PTA, academia, and industry; (4) inciting continuous reflection among PTA advocates about PTA aims, methods, and programs. Addressing these challenges will strengthen the PTA knowledge base and effectively align PTA with existing science governance discourses, such as responsible research and innovation, participatory science communication, and public dialogue.

Complex regional pain syndrome (CRPS) remains difficult to understand and to treat. The definition criteria of the IASP (International Association for the Study of Pain) in 1994 showed an overestimation of diagnosis. A revision of these criteria conducted in Budapest in 2003 permits to ameliorate the specificity of these criteria in clinical and research settings. Pathophysiology is poorly understood, only one mechanism can’t explain the observed manifestations in the CRPS: facilitated neurogenic inflammation, peripheral and central abnormalities of the central nervous system … Finally, the different laboratory tests are reviewed. Unfortunately, no laboratory test is the signature of CRPS. The diagnosis relies on history and rigorous clinical examination. Imagery method, neurophysiologic test and evaluation of inflammatory parameters help to the differential diagnosis. [less ▲]
