This paper reviews the evidence for an association between atypical subtrochanteric fractures and long-term bisphosphonate use. Clinical case reports/reviews and case-control studies report this association, but retrospective phase III trial analyses show no increased risk. Bisphosphonate use may be associated with atypical subtrochanteric fractures, but the case is yet unproven. INTRODUCTION: A Working Group of the European Society on Clinical and Economic Aspects of Osteoporosis and Osteoarthritis and the International Osteoporosis Foundation has reviewed the evidence for a causal association between subtrochanteric fractures and long-term treatment with bisphosphonates, with the aim of identifying areas for further research and providing recommendations for physicians. METHODS: A PubMed search of literature from 1994 to May 2010 was performed using key search terms, and articles pertinent to subtrochanteric fractures following bisphosphonate use were analysed. RESULTS: Several clinical case reports and case reviews report a possible association between atypical fractures at the subtrochanteric region of the femur in bisphosphonate-treated patients. Common features of these 'atypical' fractures include prodromal pain, occurrence with minimal/no trauma, a thickened diaphyseal cortex and transverse fracture pattern. Some small case-control studies report the same association, but a large register-based study and retrospective analyses of phase III trials of bisphosphonates do not show an increased risk of subtrochanteric fractures with bisphosphonate use. The number of atypical subtrochanteric fractures in association with bisphosphonates is an estimated one per 1,000 per year. It is recommended that physicians remain vigilant in assessing their patients treated with bisphosphonates for the treatment or prevention of osteoporosis and advise patients of the potential risks. CONCLUSIONS: Bisphosphonate use may be associated with atypical subtrochanteric fractures, but the case is unproven and requires further research. Were the case to be proven, the risk-benefit ratio still remains favourable for use of bisphosphonates to prevent fractures. [less ▲]

To probe the steric requirements for deacylation, we synthesized lysine-derived small molecule substrates and examined structure-reactivity relationships with various histone deacetylases. Rat liver, human HeLa, and human recombinant class I and II histone deacetylases (HDACs) as well as human recombinant NAD(+)-dependent SIRT1 (class III enzyme) were used in these studies. A benzyloxycarbonyl substituent on the alpha-amino group yielded the highest conversion rates. Replacing the epsilon-acetyl group with larger lipophilic acyl substituents led to a pronounced decrease in conversion by class I and II enzymes; the class III enzyme displayed a greater tolerance. Incubations with recombinant FLAG-tagged human HDACs 1, 3, and 6 showed a distinct subtype selectivity among small molecule substrates. The subtype selectivity of HDAC inhibitors could be predicted with these substrates and an easily obtainable mixture of HDAC subtypes. [less ▲]

We have investigated the function of subunit 8 of the cytochrome bc1 complex by generating six site-directed mutants, F46C, R51S, P62V, G64A, R91N, and W69-stop, in the cloned QCR8 gene and expressing the mutated genes in a Saccharomyces cerevisiae strain in which the chromosomal copy of QCR8 is deleted. The W69-stop mutation impairs assembly of the bc1 complex and growth of yeast on nonfermentable carbon sources as does deletion of QCR8 [Maarse, A. C., De Haan, M., Schoppink, P. J., Berden J. A., and Grivell, L. A. (1988) Eur. J. Biochem. 172, 179-184], implying that the C-terminus of subunit 8 is important for assembly and/or the stability of the bc1 complex. The F46C, R51S, P62V, G64A, and R91N mutations do not affect the growth of yeast on nonfermentable carbon sources, not do they lower the activity or alter the inhibitor sensitivity of the bc1 complex. Rather, some of the mutations increase the cytochrome C reductase activity of the bc1 complex by as much as 40%. However, succinate-ubiquinone reductase activity was consistently reduced 40-60% in mitochondrial membranes from these mutants, while NADH-ubiquinone reductase activity was not affected. In addition, the activation of succinate-ubiquinone reductase activity by succinate was diminished by the F46C, R51S, P62V, and G64A mutations. These results indicate that the cytochrome bc1 complex participates in electron transfer from succinate to ubiquinone in situ and also suggest an interaction between succinate-ubiquinone reductase and cytochrome bc1 complex which involves subunit 8 of the bc1 complex.

Mitochondrial F(1)F(0)-ATP synthase of chlorophycean algae is a dimeric complex of 1600kDa constituted by 17 different subunits with varying stoichiometries, 8 of them conserved in all eukaryotes and 9 that seem to be unique to the algal lineage (subunits ASA1-9). Two different models proposing the topological assemblage of the nine ASA subunits in the ATP synthase of the colorless alga Polytomella sp. have been put forward. Here, we readdressed the overall topology of the enzyme with different experimental approaches: detection of close vicinities between subunits based on cross-linking experiments and dissociation of the enzyme into subcomplexes, inference of subunit stoichiometry based on cysteine residue labelling, and general three-dimensional structural features of the complex as obtained from small-angle X-ray scattering and electron microscopy image reconstruction. Based on the available data, we refine the topological arrangement of the subunits that constitute the mitochondrial ATP synthase of Polytomella sp. [less ▲]

Reaction of yeast RNA polymerase I with pyridoxal 5′-phosphate and sodium borohydride under conditions which inactivate the enzyme results in the specific binding of pyridoxal 5′-phosphate to subunits of 185,000, 137,000, 48,000 and 36,000 daltons. Nucleotides, which protect the enzyme from inactivation specifically inhibit the binding of pyridoxal 5′-phosphate to subunits of 185,000 and 137,000 daltons. DNA which also protects the enzyme from inactivation by pyridoxal 5′-phosphate prevents the binding of the reagent to the four polypeptides. These results suggest that subunits of 185,000 and 137,000 are involved in interactions with both nucleotides and DNA presumably of the type leading to initiation and/or polymerization and that subunits of 48,000 and 36,000 daltons also bind to DNA but this interaction is not strictly required for polymerase activity.

Rapport de recherches final présentant les résultats du projet de recherches SAFE (2009-2012). Le projet de recherches SAFE portait sur l'évaluation énergétique des quartiers périurbains existants dans le but d'en améliorer l'efficience énergétique par le développement de nouveaux modes de conception et de planification des tissus périurbains. L'objectif concret de ce projet de recherche est d'offrir un outil informatique interactif, accessible sur le web (www.safe-energie.be), qui permette d'évaluer l'efficience énergétique des lotissements wallons existants et de comparer différentes stratégies de renouvellement périurbain. Cet outil est destiné à l'ensemble des acteurs du processus de conception, réalisation et rénovation du milieu urbain. L'outil informatique développé estl'aboutissement d'une recherche de pointe basée sur la modélisation énergétique de quartiers périurbains à l'aide de simulations du microclimat urbain (logiciel de CFD, etc), de simulations dynamiques des consommations énergétiques des bâtiments pendant leur utilisation et de simulations énergétiques des fragments urbains sur l'ensemble de leur cycle de vie (intégrant l'évaluation énergétique des bâtiments, du transport et des réseaux d'énergie).

The complement system is a crucial part of innate and adaptive immunity which exerts a significant evolutionary pressure on pathogens. It has selected for those pathogens, mainly microorganisms but also parasites, that have evolved countermeasures. The characterization of how pathogens evade complement attack is a rapidly developing field of current research. In recent years, multiple complement evasion strategies have been characterized. In this review, we focus on complement escape mechanisms expressed by hematophagous parasites, a heterogeneous group of metazoan parasites that share the property of ingesting the whole blood of their host. Complement inhibition is crucial for parasite survival within the host tissue or to facilitate blood feeding. Finally, complement inhibition by hematophagous parasites may also contribute to their success as pathogen vectors. [less ▲]

La bande dessinée est-elle un médium moderne ou postmoderne ? Les dessinateurs les plus créatifs, chevilles ouvrières des maisons d’édition indépendantes, défendent la modernité du médium. On pense notamment à la position de Jean-Christophe Menu sur le sujet. Dans le « manifeste » de l’Association (les 3 numéros de la revue « théorique » L’éprouvette), plusieurs auteurs défendent l’actualité de la notion d’Avant-Garde. Leur thèse se résume comme suit : si la peinture ou la littérature ont vu l’époque des Avant-Guardes laisser place à la postmodernité, la bande dessinée, au moins, n’a pas encore été touchée par la désillusion qui lui est propre. Immaturité revendiquée des dessinateurs qui croient encore pouvoir révolutionner totalement les codes de leur médium et proposer une version neuve de la bande dessinée, en rupture avec ses origines. Cette notion de « rupture » (ou de « crise » d’ailleurs) est tout-à-fait centrale et caractéristique de la modernité – la postmodernité, de par son système de citations (même impertinentes et détournées), ne fait que renouer avec un passé stérile qu’elle recycle infiniment (parce qu’elle est dénuée de tout enjeu révolutionnaire, de toute lutte interne). Mais par ailleurs, la bande dessinée est traversée par des éléments de la postmodernité. Du point de vue de son contenu, elle marque de plus en plus un désaccord radical avec la modernité consumériste, le culte de la marchandise et des effets de « mode », la vie citadine et l’homogénéisation des masses. Elle est l'un des lieux d’expression privilégiés de la désillusion du peuple relativement aux grandes utopies de transformation rationnelle du monde et d’émancipation de l’homme (expression privilégiée des minorités de genre ou de race – ce qui est souvent mis en exergue dans les cultural studies). Par ailleurs, à suivre Jean-François Lyotard, la postmodernité ne se caractérise pas uniquement par sa violente performativité (le culte de l’Utilité remplaçant dans les savoirs scientifiques celui de la Vérité), mais elle montre aussi une prise en compte croissante des instabilités et développe une « paralogie » que nourrirait probablement une certaine bande dessinée (et plus généralement une certaine para-littérature).

We present a new design of a phase mask coronagraph implemented with subwavelength diffractive optical elements consisting of optimized surface-relief gratings. Phase mask coronagraphy is a recent technique that seeks to accommodate both high dynamic and high angular resolution imaging of faint sources around bright astrophysical objects such as exoplanets orbiting their host stars. The original design we propose is a new, integrated, and flexible solution to the pi phase-shift chromaticity of the phase mask coronagraphs. It will allow broadband observations, i.e., shorter integration times and object characterizations, by means of spectroscopic analysis. The feasibility of the component manufacturing is also considered through a tolerance study. [less ▲]

En matière culturelle, l’Africain postcolonial est partagé entre les normes traditionnelles (ou ancestrales) et modernes (ou héritées du colon). Si la description de cette dualité abonde dans la littérature, la question du taux de connaissance de cette dualité, de son acceptation et de sa défense préoccupe très peu. Pourtant, elle devrait permettre de connaitre l’étendue de l’ambigüité qui anime les populations. Cet article répond à ce déficit et présente un état des lieux auprès de 1013 victimes du choc de normes successorales (tradition vs. modernité) en contexte postcolonial camerounais. Au préalable, les 6 points d’opposition entre les deux normes sont présentés. L’historique de la dualité juridique à l’origine de ces contrastes et le fondement psycho-anthropologique des visions du monde fondatrices de l’une et l’autre norme permettent de cerner l’irréductibilité des oppositions.

This study aims at investigating influencing factors of achievement in higher education (1st year of University). The analyses of empirical data collected in French-speaking Belgium show that on average girls outperform boys; the gender gap is not explained by students’ previous career. Besides, interaction effects between gender and parents’ level of education are observed. Gender achievement gaps are larger when parents’ level of education is higher. Moreover, when the father’s level of education is kept under control, the mother’s level of education is not related to boys’ achievement, but is related to girls’ achievement. [less ▲]

L'objet de cet ouvrage est de proposer un système d'évaluation mutli-critères des programmes d'accès à l'électricité dans les régions rurales des pays en développement. Une grille d'évaluation est établie sur base d'une large revue de littérature et d'exemples concrets d'échecs ou de succès de projets d'électrification rurale. La grille d'analyse est ensuite appliquée à un projet particulier mené à bien par STG International au Lesotho. Ce projet consiste en une solution novatrice de sytème à concentration solaire couplé à un cycle de Rankine organique pour la génération combinée d'eau chaude et d'électricité. L'application de la grille d'analyse permet in fine de formuler un certain nombre de recommendations visant à maximiser les chances de succès du projet. [less ▲]

Stress at work has become a major problematic in Europe this last decade. Several methods for diagnosis and intervention can be listed. In this context, an examination of interventions taking place in companies is necessary: what are the reasons for implementing stress prevention programmes (SPP)? Which ones are the most frequent? What are the success and failure factors for implementing SPP? In order to answer those questions, a large scale survey was implemented in Belgian companies (N=210). Results show that a) companies mainly use diagnosis to fulfil legal obligation, b) psychosocial risk assessments are less implemented in small companies (less than 50 workers), c) interventions are rarely systematically evaluated, d) most interventions target work environment, and specifically organisational (rather than ergonomic) outcomes, and e) communication/participation and methodological outcomes facilitate implementation of intervention, whereas changes and time/finances outcomes are blocking factors. To conclude, we can say that our survey emphasizes the relevance of public-awareness campaign (particularly towards small companies) about the necessity of implementing stress prevention program and of proceeding to systematic evaluation of such program. Public-awareness campaign is also needed concerning the impact of facilitating outcomes such as communication, participation and methodology, and of blocking outcomes such as organizational changes, time constraints and costs. Theoretically speaking, our study stresses first the prevalence of work-related interventions that are organisational rather than ergonomic or individual. Another point rather new regarding the existing literature is the blocking aspect of organizational changes. [less ▲]

With the improvement of survival rates following cardiac transplantation, the probability of recipients developing extracardiac disease is increased. Three cases are reported of abdominal aortic aneurysm successfully operated on in cardiac allograft recipients 1 to 4 years after transplantation. Indications for transplantation were valvular, idiopathic and ischaemic cardiomyopathy. Post-transplant hypertension and hyperlipidaemia may have played a role in the rapid growth of the aneurysms. Cardiac function and the incidence of graft atherosclerosis were assessed before surgery by coronary angiography. All three patients were discharged from hospital. Abdominal aortic aneurysm resection may be a safe procedure in cardiac transplant patients. In view of the rapid increase in the size of the aneurysms in transplanted patients, careful screening should be performed during follow-up. [less ▲]
