The purpose of this study was to investigate the reproducibility of findings derived from a new iso-inertial dynamometer during bench press (BP) and squat (SQ) and to provide descriptive data for recreational athletes. A position transducer and accelerometer were combined to assess velocity and power during free weight lifting exercises. Simulated movement with a pulley system revealed the excellent technical consistency of the dynamometer. Sixteen male subjects participated in the study. Iso-inertial tests consisted of lifting as fast as possible four different relative loads (35, 50, 70, 90% 1RM in BP and 45, 60, 75, 90% 1RM in SQ). The test was repeated one week later. Analysis of variance revealed no significant variation between sessions or trials. Reproducibility was better in velocity than in power, although it remained fairly good in both exercises (coefficients of variation [CV] never exceeding 10%) except for the time to peak power parameter. Descriptive data confirmed the classical force-velocity and force-power relationships for BP and SQ. In conclusion, this study demonstrated reliable measurements in BP and SQ iso-inertial exercises. Monitoring force-velocity and force-power relationships offers an original functional approach in strength training supervision. [less ▲]

In this thesis, we present our contributions to the CoRoT mission and to the search for exoplanets with the photometric transit method. We developped a spectroscopic analysis method, APASS, which allows to obtain a precise determination of atmospheric physical parameters and abundances for stars with an unnegligeable rotational speed. We present APASS and the high-precision results we obtained for main target stars of the asteroseismological part of the CoRoT mission. Our results are in agreement with those obtained by other authors using different analysis methods, while beeing more precise. Furthermore, they show that the use of a spectroscopic analysis method based on equivalent widths measurements by gaussian or Voigt profiles fitting should be avoided for stars whose rotational velocity is significantly higher then the Sun’s, and that a method using synthetic spectra fitting for which the convolution is a free parameter should be prefered. Next, we investigate the potential of extrasolar planet transit surveys. We show that CoRoT has a very high potential for the detection of close-in giant planets, better than the one of the KEPLER mission. This latter reveals to be better for the detection of terrestrial planets. Nevertheless, CoRoT could detect a few giant telluric planets of short orbital period, provided that this kind of object is frequent in our galaxy. For ground-based surveys, our results based on the use of large telescopes and wide-field cameras seem to indicate that an important potential is also available from the ground. These results are nevertheless less reliable, mainly because of the lack of knowledge about the influence of systematic effects, and additional investigations using actual data will be necessary. We present then the deconvolution method MCS and the way we adapted it to planetary transit photometry. We present the results we obtained after analysis of actual data for OGLE-TR-123 (VLT/FORS2 data) and OGLE-TR-132 (VLT/FORS2 and NTT/SUSI2 data). These results are very encouraging and demonstrate the high potential of MCS for this kind of high-precision analysis. Finally, we present the future improvements we intend to install to obtain a still higher level of precision and to increase the speed of analysis. [less ▲]

Poorly water-soluble drugs such as nifedipine (NIF) (similar to 20 mu g/mL) offer challenging problems in drug formulation as poor solubility is generally associated with poor dissolution characteristics and thus with poor oral bioavailability (BCS class H drugs). In order to enhance these characteristics, formulation of NIF as nanocrystals was carried out. NIF nanoparticles (NP) were prepared using high-pressure homogenization (HPH). Solubility and dissolution characteristics have been reported in previous work to be significantly enhanced for NIF NP. Influence of NIF particle size on NIF permeation rate across intestinal cell models (Caco-2 and HT29-5M21 cultures and co-cultures) was investigated in order to complement these promising in vitro data. Apical to basolateral transfer studies were carried out across Caco-2 and HT29-5M21 cultures and co-cultures. Caco-2/HT29-5M21 co-cultures (seeding ratio 3: 1) were evaluated to better represent in vivo intestinal conditions. The influence of chitosan in the NIF NP formulation with regard to in vitro NIF permeation rate was also evaluated. These studies showed that NIF permeation rate across the different in vitro models evaluated can be significantly enhanced (approximate to 6-fold) by formulation of NIF as nanoparticles. No significant difference was observed either in the presence of chitosan in the formulation or between the three cell models evaluated. To complement these observations, preliminary in vivo pharmacokinetic evaluations in Sprague-Dawley rats, in the fed and fasted states, were also carried out for both un-milled NIF and NIF NP.

Two-dimensional electrophoresis was used to investigate the effects of a QTL for muscle hypertrophy on sarcoplasmic protein expression in ovine muscles. In the Belgian Texel breed, the QTL for muscle hypertrophy is localized in the myostatin-encoding gene. Based on microsatellite markers flanking the myostatin gene, we compared the hypertrophied genotype with the normal genotype. The average age of the sheep was 3 mo. Among the 4 muscles studied, in the hypertrophied genotype only the vastus medialis was normal, whereas the semimembranosus, tensor fasciae latae, and LM were hypertrophied. In the hypertrophied genotype, these muscles showed upregulation of enzymes involved in glycolytic metabolism together with oxidative metabolism in LM. Certain chaperone proteins, including glutathione S-transferase-Pi, heat shock protein-27, and heat shock cognate-70, were also more highly expressed, probably due to increased use of energetic pathways. Expression of the iron transport protein transferrin was increased. Alpha-1-antitrypsin was the only protein showing a similar pattern of expression (i.e., less expressed) in all 4 muscles of the hypertrophied genotype. It is suggested that transferrin and alpha-1-antitrypsin may interact to reinforce myogenic proliferative signaling. [less ▲]

Human transmission of Salmonella enterica from new companion animals is usually suspected even though very few data according Salmonella infections in these animal species are available. The prevalence of Salmonella enterica infections in the digestive tract of 450 new companion animals ( 45 ferrets, 7 birds, 308 rodents, 82 rabbits and 8 reptiles) coming from pet shops or individual owners was determined by bacteriological examinations of anal swabs or pooled fresh faeces. Only one Salmonella Enteritidis strain was isolated from a ferret in a pet shop. The symptomatic or asymptomatic Salmonella carriage in ferrets, rodents and rabbits is thus not as frequent as what was suspected. [less ▲]

L’objectif de la présente étude a été la caractérisation des profils plasmatiques de la protéine associée à la gestation (PAG) et de la progestérone au cours de la gestation et deux semaines après le part chez la race Ouled Djellal. Vingt-cinq brebis ont été prélevées hebdomadairement après synchronisation des chaleurs et monte naturelle. Les concentrations de PAG et de progestérone ont été déterminées par dosage radio-immunologique. Deux femelles n’ont pas été fécondées tandis que 23 ont eu des gestations considérées comme normales (n=18) ou pathologiques (n=5). Chez 18 brebis (12 gestations simples et 6 multiples), les concentrations de PAG et de progestérone ont été significativement influencées par le stade de la gestation (P<0.0001) et non par le nombre de fœtus. Des profils individuels ont été décrits chez 7 brebis dont 3 femelles ayant eu des pertes embryonnaires, et 2 brebis ayant avorté (66e et 110e jours), et enfin chez 2 brebis ayant donné naissance à terme chacune à un agneau vivant et expulsé au moment de la mise-bas 1 ou 2 fœtus momifié(s). Les concentrations en PAG ont été plus faibles chez les femelles ayant de fœtus momifiés en parallèle avec des fœtus vivants. [less ▲]

Cases of chronic wasting disease (CWD) in wild cervids have yet not been reported in Europe, whereas the disease is considered enzootic in free-ranging mule deer, Rocky mountain elk and white-tailed deer in the area of Colorado, Wyoming, and Nebraska. New foci of CWD continue to be detected in other parts of the United States. However, no large-scale active epidemiosurveillance of European wild cervids is yet installed in Europe. In accordance with the opinion of the European Scientific Steering Committee, a preliminary (active) surveillance scheme was installed, in order to improve the knowledge of the CWD status of wild cervids (roe deer) in the Northern part of Belgium. Spleen samples (n=206) and brain samples (n=222) of roe deer collected in the Northern part of Belgium, were examined for CWD using the antigen-capture enzyme-linked immunoassay (EIA) of IDEXX. Afterwards, the EIA was systematically confirmed by immunohistochemistry using three antibodies, namely R524, 2G11 and 12F10. There were no indications on the occurrence of TSE in any of the samples. A Bayesian framework was used for the estimation of the true prevalence of CWD in the Northern part of Belgium that was estimated to have a median value of zero with a 95th percentile value of 0.0049 and 0.0045 for spleen and brain samples respectively.

Inverse methods offer a powerful tool for the determination of the elasto-plastic material properties. Contrary to standard tests, these methods can deal with heterogeneous stress and strain-fields which have a larger information contents and hence allow the simultaneous identification of several material parameters. Moreover, it is expected that the obtained material parameters are more accurate, since these heterogeneous deformation fields are much closer to those occurring in real (metal) forming operations. The principle of the inverse method for the identification of material parameters presented in this paper is to compare an experimentally measured strain field to that computed by a Finite Element (FE) model. The material parameters in the FE model are iteratively tuned in such a way that both strain fields match each other as close as possible. One of the building blocks in this identification procedure is the updating algorithm for the material parameters in the FE model. The key problem of this updating algorithm is the determination of the sensitivity matrix, which expresses the sensitivities of the strains with respect to the material parameters. This paper presents an analytical method for the calculation of this sensitivity matrix in case of simple tensile tests. [less ▲]

This communication reports experimental results on the superconducting properties of YBaCuO thick films prepared by electrophoretic deposition on silver substrates. The magnetic shielding properties of the coatings were characterised by various methods. First, the electrical resistance and the transport critical current density, Jc, were determined. Our coatings exhibit a superconducting transition at a temperature of 90 K. Next, shielding characterisations were carried out at 77 K for samples having either a slab or a cylindrical geometry. In both cases, the frequency of the applied magnetic field was 103 Hz; the field behind the shielding wall was measured by a pick-up coil connected to a lock-in amplifier. In the case of cylindrical samples and for an applied induction lower than 1 G, the field inside the shielding enclosure is reduced by a factor greater than 106 (i.e. 120 dB) with respect to the applied field.
