Drugs used for the prevention and the treatment of osteoporosis exert various favourable and unfavourable extra-skeletal effects whose importance is increasingly recognized notably for treatment selection. INTRODUCTION: The therapeutic armamentarium for the prevention and the treatment of osteoporosis is increasingly large, and possible extra-skeletal effects of available drugs could influence the choice of a particular compound. METHODS: The present document is the result of a national consensus, based on a systematic and critical review of the literature. RESULTS: Observational research has suggested an inverse relationship between calcium intake and cardiovascular diseases, notably through an effect on blood pressure, but recent data suggest a possible deleterious effect of calcium supplements on cardiovascular risk. Many diverse studies have implicated vitamin D in the pathogenesis of clinically important non-skeletal functions or diseases, especially muscle function, cardiovascular disease, autoimmune diseases and common cancers. The possible effects of oral or intravenous bisphosphonates are well-known. They have been associated with an increased risk of oesophageal cancer or atrial fibrillation, but large-scale studies have not found any association with bisphosphonate use. Selective oestrogen receptor modulators have demonstrated favourable or unfavourable extra-skeletal effects that vary between compounds. Strontium ranelate has a limited number of non-skeletal effects. A reported increase in the risk of venous thromboembolism is not found in observational studies, and very rare cases of cutaneous hypersensitivity reactions have been reported. Denosumab has been introduced recently, and its extra-skeletal effects still have to be assessed. CONCLUSION: Several non-skeletal effects of bone drugs are well demonstrated and influence treatment choices. [less ▲]

OBJECTIVE: The systemic inflammatory response to cardiopulmonary bypass (CPB) possibly increases microvascular permeability to plasma proteins, leading to capillary leak syndrome. The study was conducted to elucidate any protein leakage in newborns using Evans blue dye as tracer. DESIGN: Prospective controlled study. SETTING: University-affiliated heart center. PARTICIPANTS: Eleven neonates with transposition of the great arteries. INTERVENTIONS: Plasma interleukin-6 (IL-6), IL-10, fractional escape rate (FER) of an intravenous bolus of Evans blue, and colloid osmotic pressure (COP) were assessed before and after surgery (statistics: median and 25th-75th percentile, Friedman's 2-way analysis of variance, and Wilcoxon matched-pairs signed-rank test [before and after surgery]). MEASUREMENTS AND MAIN RESULTS: All patients had an uneventful intraoperative course. The demographic and operative data were age 11 (10-13) days, body weight 3.2 (3.0-3.3) kg, CPB time 132 (123-144) minutes, and aortic cross-clamp time 66 (64-78) minutes. The proinflammatory IL-6 increased 60-fold and the anti-inflammatory IL-10 only 3-fold after CPB. FER, however, was not changed, whereas COP was significantly reduced after CPB. CONCLUSIONS: In contrast to the expectation, the escape rate of Evans blue, reflecting the extravasation of albumin, was not increased after CPB. However, reduced COP, hypothermia, and also a reduced lymphatic drainage may contribute to edema formation. The present data do not support the hypothesis of a capillary leak after CPB in newborns.

Cold-loving or psychrophilic organisms are widely distributed in nature as a large part of the earth's surface is at temperatures around 0 degrees C. To maintain metabolic rates and to prosper in cold environments, these extremophilic organisms have developed a vast array of adaptations. One main adaptive strategy developed in order to cope with the reduction of chemical reaction rates induced by low temperatures is the synthesis of cold-adapted or psychrophilic enzymes. These enzymes are characterized by a high catalytic activity at low temperatures associated with a low thermal stability. A study of protein adaptation strategies suggests that the high activity of psychrophilic enzymes could be achieved by the destabilization of the active site, allowing the catalytic center to be more flexible at low temperatures, whereas other protein regions may be destabilized or as rigid as their mesophilic counterparts. Due to these particular properties, psychrophilic enzymes offer a high potential not only for fundamental research but also for biotechnological applications. [less ▲]

We present a solution to improve the performances of coronagraphs in general for the detection of exo-planets. We simulate several kinds of coronagraphic systems using an IDL software, with the aim of evaluating the gain obtained using an adaptive hologram. The detection limit in flux ratio between a star and a planet observed with an apodized Lyot coronagraph characterized by wavefront bumpiness imperfections of lambda/20 (resp. lambda /100) turns out to be increased by a factor 1`000 (resp. 1`000`000) when equipped with an hologram. This technique could provide a direct imaging of an exo-earth at a distance of 11 parsec with a space telescope with a mirror quality analog to the HST, and with a diameter analog to the JWST.

Aims. We present a solution to improve the performance of coronagraphs for the detection of exo-planets. Methods. We simulate numerically several kinds of coronagraphic systems, with the aim of evaluating the gain obtained with an adaptive hologram. Results. The detection limit in flux ratio between a star and a planet (Fs /Fp ) observed with an apodized Lyot coronagraph characterized by wavefront bumpiness imperfections of λ/20 (resp. λ/100) turns out to be increased by a factor of 10^3.4 (resp. 10^5.1 ) when equipped with a hologram. Conclusions. This technique could provide direct imaging of an exo-Earth at a distance of 11 parsec with a 6.5 m space telescope such as the JWST with the optical quality of the HST. [less ▲]

L'article esquisse le nouveau visage de l'extrême droite en Europe : elle est diverse (par exemple elle peut être régionaliste ou nationaliste, plutôt libérale ou anti-libérale) même si elle conserve sa logique centrale du bouc émissaire, essentiellement l'immigré et plus encore l'immigré musulman. Elle ne pourra plus être combattue essentiellement à travers la dénonciation des horreurs du nazisme, vu qu'une partie croissante de l'extrême droite ne se réfère plus au fascisme historique et même, de plus en plus souvent, le condamne.

We began making CO2 measurements in Belgian caves in 1966. Analyses were conducted in cave halls, galleries, fissures and shafts, in various seasons and at different levels above the floors of the conduits, and in the absence or presence of other human beings. Our first results were published in 1968. From that time on, we have carried out studies in Poland, Quebec, China and other countries but we have focused most of our work in Belgium. We have discovered over these forty years of study, a strong increase in the observed values of CO2 in Belgian caves. For example, a few of our observations follow. “Trou Joney” (Comblain-au-Pont, province of Liege) is a small and shallow cave. We measured at the central point of the main gallery, 1870 ppm CO2 in July 1966, and 13800 ppm at the same location in July 2007. At the bottom of the shaft of the “Comblain-au Pont” cave, we measured 600 ppm in July 1966 and found 1500 ppm in July 2008. In “La Merveilleuse” cave (Dinant, province of Namur), we measured 800 ppm at the central point of the Big Hall in August 1990, rising to 1700 ppm in August 2008. In the main gallery of the “Fontaine de Rivire” cave (Hamoir, province of Liege), we found 5000 ppm in August 1972, increasing to 9400 ppm in 2008. We conclude that the CO2 content of the atmospheres of many caves in Belgium at least, is very sharply getting higher. The increase is very variable, but omnipresent. Are our measurements significant? We believe that we have validated our instruments and our methods. The increase is probably not a result of local industrial activities. The CO2 curves of Mauna Loa Observatory (Hawaii) and “Mace Head” (Ireland) both show an increase of atmospheric carbon dioxide during the last half century. However, the upsurge of CO2 observed in the caves is much greater than the increase in those well-known surface measurements. There is a very complex interrelationship between temperature, vegetation and biomass activity, and CO2 in the soil and underground. The increase of any one of these three parameters can induce changes in the two others, and hence in the partial pressure of CO2 in cave air. [less ▲]

In recent years the revival of the far right and anti-Semitic, racist and fascist organizations has posed a significant threat throughout Europe. Mapping the Extreme Right in Contemporary Europe provides a broad geographical overview of the dominant strands within the contemporary radical right in both Western and Eastern Europe. After providing some local and regional perspectives, the book has a series of national case studies of particular countries and regions including: Austria, Belgium, Bosnia-Herzegovina, Croatia, Eastern Europe, France, Germany, Greece, Italy, Malta, Portugal, Romania, Scandinavia, Serbia, Spain, Switzerland, Turkey, Ukraine and the United Kingdom. A series of thematic chapters examine transnational phenomena such as the use of the Internet, the racist music scene, cultural transfers and interaction between different groups. Drawing together a wide range of contributors, this is essential reading for all those with an interest in contemporary extremism, fascism and comparative party politics. [less ▲]
