Although there is strong evidence supporting the short-term efficacy and safety of anti-tumour necrosis factor-alpha agents, few studies have examined the long-term effects. We evaluated 511 patients with long-standing refractory rheumatoid arthritis treated with intravenous infusions of infliximab 3 mg/kg at weeks 0, 2, 6, and 14 and every 8 weeks thereafter for 4 years. Among the initial 511 patients included in the study, 479 could be evaluated; of these, 295 (61.6%) were still receiving infliximab treatment at year 4 of follow-up. The most common reasons for treatment discontinuation were lack of efficacy (65 patients, 13.6%), safety (81 patients, 16.9%), and elective change (38 patients, 7.9%). Analysis of disease activity scores (DAS28 [ disease activity score based on the 28-joint count]) over time showed that, after the initial rapid improvement during the first 6 to 22 weeks of therapy, a further decrease in disease activity of 0.2 units in the DAS28 score per year was observed. DAS28 scores, measured at week 14 or 22, were found to predict subsequent discontinuation due to lack of efficacy. In conclusion, long-term maintenance therapy with infliximab 3 mg/kg is effective in producing further reductions in disease activity. Disease activity measured by the DAS28 at week 14 or 22 of infliximab therapy was the best predictor of long-term attrition. [less ▲]

The Multicoloured Asian Ladybird, Harmonia axyridis Pallas (Coleoptera: Coccinellidae) is known to thrive principally in shrubby and arboreal habitats. Its occurrence in agroecosystems remains poorly documented. This study focuses on the occurrence of this exotic species and its seasonal abundance in various field crops. The abundance of adults and larvae of H. axyridis was evaluated over a four-year period, from 2009 to 2012, in four important agronomical crops (wheat, corn, broad bean and potato) in Belgium. A total of 28 aphid predator species were observed including 14 coccinellid species, 13 hoverfly species and one lacewing species. H. axyridis is present and reproduces in all of the four crops studied, with the largest numbers recorded in corn and broad bean crops. In corn, H. axyridis numbers were found to increase over the four inventoried year, reaching 86% of the aphid predators in 2012, while it represented only 15% in 2009. H. axyridis was not always recorded where aphids were abundant, e.g. aphids were abundant on wheat where no H. axyridis were recorded. H. axyridis starts reproducing after the peak in aphid population, suggesting that H. axyridis is able to complete its development by feeding on alternative prey such as larvae and pupae of the same and other species of ladybird and other aphidophagous species. H. axyridis is often considered to be bivoltine but it only completes one generation per year in field crops. The second generation generally develops late in the season in other habitats. Harmonia axyridis is an invasive and an intraguild predator present in high quantities in some specific crops. In these crops, H. axyridis could negatively impact on population of native species due to IGP observed in several other studies. [less ▲]

Fourcroy (1755-1809) first dealt with the question of « Cancer », as the word was understood during the XVIIIth century, in the article “Anti-cancéreux” of the l’Encyclopédie méthodique. Médecine, t. III, 1790. He divides the remedies between « external » and « internal ». He distinguishes among the firsts the « actual cauteries » (sometimes called « actual caustics” in another article by Fourcroy) which use fire and the instruments carrying the latter or a strong heat upon the “glands and the parts affected by cancer”. We particularly focus on the Chinese moxa and on the technic of concentration of sun’s rays established by some “Lecomte, surgeon in Arcueil ». We discuss the notion of cancerous “virus” in the prospect of an awakening of the principle of metastasis, notably in Le Dran and from the point if view of a possible crossing from the traditional humoral theory to a sort of “localizer-solidism”. The “external” remedies also consist of “chemical caustics” (nitrate of mercury, muriate of antominy, caustic potassium, nitrate of silver, etc.). Fourcroy mentions three types of “painkillers” or “ narcotic” whose “external applying has been recommended”, but “which are only likely to soothe the pains”: the “swam-skin” (?) , the virous lettuce and the carrot. He deals elsewhere with opium. We distinguish, among the remedies applied externally and internally the hemlock, to which Fourcroy will devote another article in the Méthodique. We point the relationship linking this article to Johan Andreas Murray’s Apparatus medicaminum (1776) and to Christoph Jakob Mellin’s Praktische materia medica (1778). Other internal remedies are quoted, especially from the famous Anton Störck: the aconite, the datura stramonium, the arsenic, the mercury, etc. But all those enemies of the disease have failed, Fourcroy concludes: “How could we admit, after those facts, that exist some anti-cancerous remedies; it is just a word that can give to the ill persons some hope; man needs illusions, even in the greatest misfortune”.

Studies of single crystal YNi2B2C have revealed a fourfold anisotropy of the equilibrium maenetization in the square crystallographic basal plane. This pi/2 periodicity occurs deep in the superconductive mixed state. In this crystal symmetry, an ordinary superconductive mass anisotropy (as in usual London theory) allows only a constant, isotropic response. In contrast, the experimental results are well described by generalized London theory incorporating nonlocal electrodynamics, as needed for this clean, intermediate-kappa superconductor. [less ▲]

The crude venom of Conus virgo was analyzed by Fourier transform mass spectrometry (FTMS) using both nano-electrospray ionization and MALDI. The analyses were performed directly on the crude venom, without chromatographic separation. The mass fingerprinting of the venom yielded 64 distinct molecular masses in the range 500-4500 Da with two major components at 1328.5142 and 1358.5592 Da. To facilitate the de novo sequencing of these compounds, the disulfide bonds of all components were reduced for the whole venom. The mass accuracy, resolution and sensitivity provided by FTMS were necessary to complete the sequencing of the two new peptides named ViVA and ViVB, that turned out to be conotoxins belonging to the T-superfamily, with the disulfide framework V. The peptides shared 80% similarity and as often observed for this class of compound, they were highly post-translationally modified: amidated C-terminus, pyroglutamic acid residue at the N-terminus and two disulfide bonds. Complementary online nano-LC-nano-ESI-FTMS experiments were undertaken. Among the 130 molecular masses found in the coupling experiments, only 45 were common with those obtained in the direct approach, which means that 21 compounds observed by nano-ESI-FTMS were not detected. This clearly shows that some discriminations against some classes of compounds occur when a chromatographic step is used before mass spectrometry. [less ▲]

We report results of a recent engineering study of an enhanced version of the Fourier-Kelvin Stellar Interferometer (FKSI) that includes 1-m diameter primary mirrors, a 20-m baseline, a sun shield with a ±45° Field-of-Regard (FoR), and 40K operating temperature. The enhanced FKSI is a two-element nulling interferometer operating in the mid-infrared (e.g. ˜ 5-15 μm) designed to measure exozodiacal debris disks around nearby stars with a sensitivity better than one solar system zodi (SSZ) and to characterize the atmospheres of a large sample of known exoplanets. The modifications to the original FKSI design also allows observations of the atmospheres of many super-Earths and a few Earth twins using a combination of spatial modulation and spectral analysis.

En Communauté française de Belgique, une vingtaine de bénévoles sont nécessaires pour un club de football. Alors que depuis trente ou quarante ans, la société évolue vers toujours plus d'individualisme et que l'argent tient une place déterminante, même dans le sport, ces bénévoles représentent un contre-pouvoir, défendant un autre système de valeur, où l'altruisme occupe une place importante. Motivés par la passion du sport, ils trouvent plaisir, épanouissement et reconnaissance sociale en donnant de leur temps, pour remplir diverses fonctions, plus ou moins importantes selon le statut amateur ou professionnel du club. Coup de chapeau à ces hommes et femmes de l'ombre à qui toutes les stars du football doivent une part de leur réussite et de leur gloire. [less ▲]
