The present study explores the shape changes of cranial structures directly involved in food capturing during growth after reef settlement in two species of Pomacentridae (Dascyllus aruanus and Pomacentrus pavo). Landmark-based geometric morphometrics were used to study allometric patterns and related shape changes in four skeletal units: neurocranium, suspensorium and opercle, mandible and premaxilla. At settlement, the larvae of both species have a relatively similar morphology, especially with respect to the mandible. Their shapes suggest a feeding mode defined as ram/suction-feeding. Ontogenetic shape changes show a shift to a suction feeding mode of prey capture. The main transformations involved are an increase in height of the suspensorium and the opercle, an elevation of the supraoccipital crest, a relative shortening of the mandible, and a lengthening of the ascending process of the premaxilla. Shape changes of the mandible in the two studied species also reflect an increase of biting capacities. The high disparity between adult shape results from differences in the rate and in the length of ontogenetic trajectories, from divergence of the ontogenetic trajectories (neurocranium, mandible, and premaxilla) and parallel shifts of the trajectories in the size-shape space (suspensorium and opercle). In an evolutionary context, allometric heterochronies during ontogeny of different skeletal unit of the head may be considered as a basis for the explanation of the diversity of damselfishes.

A fully differentiated reconstructed interfollicular feline epidermis (RFE) was recently developed in vitro. It was shown to be relevant for the study of Microsporum canis-epidermal interactions. In this study, RFE was evaluated as a potential model for the in vitro screening of drugs against M. canis. As a preliminary step, the minimum inhibitory concentration of miconazole nitrate against M. canis IHEM 21239 grown on Sabouraud's dextrose agar was determined to be 0.3 microg mL(-1). RFE grown at the air-liquid interface was cultured for 24 h in RFE culture medium, supplemented with either miconazole (range 0.1-1 microg mL(-1)) or its solvent (dimethylsulfoxide). Then, RFE was inoculated in triplicate with 1 x 10(5 )M. canis arthroconidia and incubated for five additional days. To evaluate fungal growth, RFE was processed for routine histopathology, three serial sections being performed across the block at 100 microm intervals. No fungal growth was detected invading or on the surface of infected RFE in the presence of miconazole concentrations equal to or higher than 0.3 microg mL (final concentration in the culture medium). This study demonstrates that RFE is an adequate model for the in vitro screening of drugs against M. canis and potentially against other skin pathogens. [less ▲]

Actuellement, le contrôle des pucerons repose en grande partie sur l'utilisation d'insecticides de synthèse. Toutefois, l'effet néfaste de ceux-ci sur l'environnement, ainsi que le développement croissant de populations résistantes conduit à rechercher de nouvelles méthodes de lutte. Parmi celles-ci, une des voies actuellement envisagée est la formulation de nouveaux bio-insecticides ciblant et perturbant les fonctions biochimiques de l'insecte. En raison de la haute spécificité des agents utilisés, ces méthodes de contrôle des ravageurs ne présentent généralement que peu de risque pour l'environnement, les espèces non ciblées et la santé humaine. Dans le contexte de la lutte contre les pucerons, la voie de biosynthèse des isoprénoïdes, et plus particulièrement les enzymes de la famille des " short-chain " isoprényle diphosphate synthases, s'avère être une cible intéressante pour le développement de ces nouveaux agents de contrôle. En effet, chez les pucerons, cette voie de biosynthèse est associée à la production des mono- et sesquiterpènes, deux classes d'isoprénoïdes jouant des rôles importants au niveau de la physiologie des pucerons [less ▲]

In cable-stayed bridge applications, the vertical vibrations of a bridge deck induce vertical motions of the cable anchors that may cause large amplitudes oscillations of the cables. This vertical motion is not collinear with the cable chord and can be split into a transverse and an axial component. The latter one is responsible for a parametric excitation. Since this phenomenon leads to serious dynamic instability, whereas the transverse component provides simple resonances only, the transverse anchor motion is often disregarded or considered in a separate analysis. However, because of the cable’s non linear behaviour, the response of the cable under both components cannot simply be added. It is thus important to consider at once this actual “cable excitation”, rather than approaching it by an axial excitation, as often reported in the study of parametric excitations. In this paper, the difference between the two modes of excitation is illustrated with a finite element model. The simplicity of the model allows an efficient parametric study of the vibrations of a cable under both excitations, for various cable inclinations and anchor frequencies. [less ▲]

Aortic pseudo-aneurysm is a well-known late complication after surgical repair of aortic coarctation. We report two cases of pseudo-aneurysm of the aortic isthmus evidenced after previous surgical repair of congenital aortic coarctation. These clinical observations give us the opportunity to underline the importance of a specific lifelong medical follow-up for patients who have undergone such surgery. [less ▲]

Soil organic matter (SOM) status was evaluated using the relationships between two independent soil variables, i.e., C respiration and the weight of particulate organic matter POM (4000-50 mu m) under different vegetation covers and ecosystems of central Belgium. A positive relationship was found between the weight of the finest POM fraction, i.e., fine POM fraction (250-50 mu m) and C respiration after 1 week (R-2 = 0.34, n = 120, p < 0.0001) and 2 weeks (R-2 = 0.28, n = 120, p < 0.0001) of incubation. Therefore, we assumed that the C respiration and the weight of fine POM might be used to evaluate the SOM status under different vegetation covers and ecosystems. (C) 2007 Elsevier Masson SAS.

This contribution summarizes considerations developed to allow a reasonable and consistent definition of the national parameters to be introduced in the Belgian national annex to chapter 9 of Eurocode 8 dealing with seismic design of masonry structures. The different aspects considered are material properties (resistance and ductility), detailing of wall-wall and wall-floor connections and rules for simple masonry buildings. The result is a set of rules consistent with the national practice and defining (i) what is allowed in Belgium for the different seismic zones, (ii) minimal requirements for simple non-engineered buildings and (iii) a procedure that can be followed to improve these rules for materials and structural systems exhibiting better properties than the minimal requirements of Eurocode 8.

French artificial insemination companies have been running a marker-assisted selection program since 2001 to determine which young bulls should be progeny tested. A first batch of 899 Holstein sires receiving their first proofs based on progeny daughters has been studied. Estimated breeding values with or without marker information were computed based on information available in April 2004, and correlated to daughter yield deviations available in 2007 for production traits. Marker-assisted estimated breeding values presented greater correlations with daughter yield deviations than those calculated using only pedigree index. The average improvement in correlation was 0.043 and ranged from +0.001 for protein yield to +0.103 for fat percentage. This gain was based on the initial and suboptimal conditions of the program and is expected to increase in the coming years because of several improvements implemented since the start of the marker-assisted selection program.

SUMMARY : High levels of high-sensitivity C-reactive protein (hs-CRP) are an independent cardiovascular marker, which may be reduced by statin therapy. JUPITER is a randomised clinical trial that compares the effects of rosuvastatin 20 mg (n = 8901) and placebo (n = 8901) in apparently healthy individuals, <br />without hyperlipidaemia (LDL < 130 mg/dl ; median 108 mg/dl), but with moderately elevated hs-CRP levels (> 2 mg/l ; median 4.25 mg/l). Rosuvastatin reduced LDL cholesterol by 50 % (to a median of 55 mg/dl) and hs-CRP by 37 %. The trial, which should last 5 years, was stopped after a median follow-up of 1.9 years because of an imbalance in favour of the rosuvastatin group. Indeed, when compared to placebo, rosuvastatin <br />was associated with a relative risk reduction in the composite primary end point of 44 %, in myocardial infarction of 54 %, in stroke of 48 %, in revascularization procedures or hospitalisations for unstable angina of 47 %, in major cardiovascular <br />events (myocardial infarction, stroke and death) of 47 % and in deaths from any cause of 20 %. Consistent effects were observed in all subgroups evaluated. The only adverse event was a higher incidence of physician-reported diabetes in the rosuvastatin group compared to the placebo group. This study demonstrates that rosuvastatin 20 mg reduces the incidence <br />of cardiovascular events, including total mortality, in apparently healthy persons without hyperlipidaemia, but with elevated hs-CRP. However, the design of the trial does not allow discriminating which part of the favourable effect results from the drastic reduction in LDL cholesterol and which part results from the reduction in hs-CRP stricto sensu.
