We present an original experimental study of the slow compaction dynamics for two- dimensional isotropic granular systems. Compaction dynamics is measured at three different scales : the macroscopic scale through the normalized packing fraction ˜ ρ, the mesoscopic scale through the normalized fraction ˜ φ of domains ideally ordered in the system, and the microscopic scale through the grain mobility μ. The domains ideally ordered are found to obey a growth process dominated by the displacement of domain boundaries. We present also preliminary results of three-dimensional simulations with a model of contact dynamics. These results allow to discuss the difference between the two-dimensional and the three-dimensional cases. [less ▲]

Various animal models have been developed to investigate the neurobiological and behavioral mechanisms of drug addiction. The most popular of these animal models include the locomotor sensitization paradigm, the place conditioning procedure and the self-administration technique. With these techniques, it is possible to mimic in rodents the major aspects of human drug addiction. The self-administration procedure is the most widely used and show an excellent natural and predictive validity. In the self-administration protocol, experimental animals, usually rats or mice, are allowed to press a lever in order to gain access to a small dose of an addictive drug. The drug may be given to the animal through the oral, the intravenous or the intracranial route of administration, according to the purpose of the study. In recent years, the classical self-administration procedure has been adapted to study the specific neurobiological basis of drug relapse. In this now called drug reinstatement paradigm, when drug self-administration behaviors are well established, an extinction procedure starts, during which lever pressing is no longer reinforced by drug access. After a number of such extinction sessions, lever pressing gradually declines and eventually stops. Drug-seeking behaviors are therefore said to be extinguished. It is then possible to test various stimuli in order to investigate whether they reinstate drug-seeking behaviors and use such a reinstatement as an animal model of drug relapse. Three types of stimuli have been shown to reinstate drug-seeking behaviors: a small priming dose of drug, drug-associated cues and a stressful stimuli. The effects of these three relapse-triggering stimuli are mediated by different neurobiological mechanisms, leading to the expectation that they may be targeted by different pharmacotherapeutic and behavioral interventions. Despite the high value of the current animal models of drug addiction, there show several limitations. In particular, it is difficult to differentiate between self-controlled and compulsive drug use in animals. As only uncontrolled compulsive drug consumption characterizes drug addiction in humans, such a limitation might explain the high frequency of false positive results in animal experiments. Indeed, it is common that therapeutic interventions successfully developed in animals later proved to be disappointing in humans. [less ▲]

An one year epidemiological study was carried out between February 2005 and January 2006 in Belgium to assess the Campylobacter prevalence in free-range broiler production. Three successive broiler flocks on 6 belgian farms were investigated for the presence of Campylobacter ssp. during the rearing period. Each flock was visited four times, before and after the outdoor rearing period. During each visit, samples were taken in the broiler houses (litter, cecal droppings, water-lines, feed, entrance premises) as well as from the outer rearing environment (open-air range). Conventional microbiological methods combined with biochemical tests were used for the Campylobacter detection, species identification and isolation. Campylobacter prevalence was very high in free-range broiler production during the experimental period. C. jejuni is the main species isolated from all contaminated samples, while mixed C. jejuni/C. coli infections sometimes occured. Contamination of the broiler flocks was increased in summer/autumn, with a 100% flocks contamination, whereas only 4 (66.7%) and 3 (50%) of the flocks became Campylobacter positive in spring and winter respectively, at the end of the rearing period. Moreover, about 53.8% of contaminated flocks were infected with Campylobacter before chicks have access to the open-air range. In 69.2% of the Campylobacter-positive flocks, the open-air range soil belonged partly of fully to environmental samples found to be Campylobacter-positive before flock infection. The other potential sources of infection were delivery tray, entrance premises floor and water-lines. The access to an open-air range seems to be an important way of contamination of broilers because Campylobacter prevalence in the flocks increased after going out. [less ▲]

Chronic arterial hypertension plays a certain role in the cognitive function decline and dementia, particularly Alzheimer's disease, through vascular lesions added to the degenerative injuries. When stroke occurs, it accelerates the development of dementia. By using antihypertensive drugs and correcting high blood pressure, the incidence of stroke has been dramatically reduced. Such treatment has also demonstrated protective efffect on stroke recurrence but also on cognitive dysfunction related to cerebrovascular complication. When severe cognitive dysfunction is present, the interest of antihypertensive treatment, its nature and the blood pressure target have not been clearly defined. An individual approach must be stimulated with an overall cardiovascular risk factors correction. [less ▲]

In many plants, flowering is promoted by a long exposure to cold, a process known as ‘vernalisation’. In Arabidopsis, the vernalisation pathway was shown to promote flowering via the repression of the FLOWERING LOCUS C (FLC) gene, which encodes a repressor of flowering. As far as we know, the genetical control of flowering is conserved among Brassicaceae, and we reported elsewhere cloning of flowering times genes of the photoperiodic pathway in Sinapis alba, based on sequence similarity with Arabidopsis. However, little is known about vernalisation in Sinapis. We therefore undertook a physiological and molecular study of this process. Plants of Sinapis were grown in non inductive short days and vernalised at 7°C, at the seedling stage. Vernalisation was found to accelerate flowering and an increasing effect was observed for vernalisation treatments longer than 2 weeks. We cloned an FLC-like sequence (SaFLC) by screening a cDNA library, and used it as a probe to perform expression analyses. We observed that SaFLC was almost completely repressed after 1 week of vernalisation, but repression was stable only after 2 weeks, which is consistent with the fact that 2-week is the minimal duration of vernalisation that promotes flowering. Hence the molecular mechanisms of vernalisation seem to be conserved in Sinapis and Arabidopsis. [less ▲]

The effect of high (H) or low (L) levels of food intake, during the preceding 51 weeks, on leptin and Insulin-like growth factor-I (IGF-I) plasma concentrations in sheep were investigated in groups of 20 adult Timahdite (non-lactating, non-pregnant) ewes. Ewes of the two treatments had similar liveweight at the start of study but there was a twofold difference in energy intake. All animals were maintained indoors under natural daylength conditions (33°53'N, 5°32'W). Blood samples were collected monthly and the statistical analyses were performed on leptin and IGF-I levels. The mean leptin plasma concentrations were higher in H ewes than L sheep (3.98±0.97 ng/ml vs 3.34±1.17 ng/ml, P<0.05). For IGF-I, from week 1 to 26, the mean plasma concentrations were higher in H ewes than L sheep (76±28 ng/ml vs 58±21 ng/ml, P<0.01). However, from week 31 to 51, the mean plasma concentrations were similar in both groups (57±24 ng/ml vs 59±25 ng/ml, P>0.05). It was concluded that the food intake levels affect significantly leptin and IGF-I plasma concentrations and consequently may be the link between food intake, body condition and reproductive performances in sheep.

YBa2Cu3O7-δ thick films have been deposited onto Ag substrates by the Electrophoretic Deposition (EPD) technique. Different microstructures and electrical behaviours were observed depending on the starting powder. Coatings prepared from commercial powder displayed significant porosity and the superconducting transition width was found to be magnetic-field dependent. Films produced from home-made coprecipitated powder are denser but contain some secondary phases. No dependence of the resistive transition as a function of magnetic field (H ≤ 20 Oe) was observed in that case. [less ▲]

After an initial positive response to anti-androgen treatment, prostate cancer (PCa) cells usually become hormone-refractory in spite of their persistent expression of the androgen receptor (AR). Overexpression of tyrosine kinase receptors in androgen-deprived PCa cells, such as those of the EGF receptor (EGFR) family, may be responsible for AR activation and growth of androgen-deprived tumours. Our goal is to understand the control of the expression of the EGFR family members by androgens in PCa. Hormone response was compared in hormone-sensitive LNCaP and hormone-insensitive DU145 PCa cell lines. These cells do not express ErbB4. EGFR, erbB2 and erbB3 protein half-life is much longer in DU145 than in LNCaP cells grown in complete medium. Dihydrotestosterone (DHT) modulates EGFR and erbB2 transcript and protein levels only in LNCaP cells. ErbB3 is not an androgen-responsive gene. EGFR mRNA and protein levels are increased while erbB2 mRNA and protein levels are decreased after DHT treatment of cells cultured in steroid-deprived medium. ErbB2 mRNA and protein levels are increased in LNCaP cells following DHT withdrawal. In order to understand the mechanisms by which androgens control the expression of EGFR and ERBB2 genes, half lifes of the corresponding mRNAs and proteins were compared in cells grown in presence or absence of DHT. The effect of DHT on EGFR gene expression is complex. Indeed, DHT stabilizes the protein. Moreover, a superinduction of EGFR mRNA was observed in cells treated with cycloheximide (CHX) before addition of the hormone, suggesting an effect on transcript stability. In contrast, erbB2 mRNA and protein stability was not affected by DHT. CHX treatment for 2h before addition of DHT suppresses the androgen-induced down-regulation of erbB2 mRNA levels. In summary, androgen-mediated regulation of EGFR and ERBB2 genes expression is complex. DHT influences EGFR gene transcription, mRNA and protein stability. DHT does not affect erbB2 mRNA and protein stability but acts indirectly on transcription. Current experiments are undertaken to verify these observations by Chromatin-IP experiments on both genes promoters. [less ▲]

Introduction : Le seuil de sensibilité à la douleur (SSD) peut être apprécié à partir de la pression minimale induisant une perception nociceptive. Ce seuil s’objective aisément en pratique clinique par une mesure dolorimétrique. Le but de ce travail consiste à comparer, à partir d’une mesure dolorimétrique, le SSD de sujets contrôles et fibromyalgiques et, d’autre part, d’établir des valeurs normatives. Patients et méthodes : Cent sujets contrôles (50 féminins et 50 masculins) et 20 patientes fibromyalgiques sont inclus dans l’étude. Le SSD des 18 points sensibles définis par le Collège Américain de Rhumatologie dans le cadre des critères de classification de la fibromyalgie est mesuré à partir d’un dolorimètre électronique. La pression transmise est augmentée graduellement au rythme de 1 kg/cm² chaque seconde et ce, jusqu’à l’apparition d’une véritable douleur, et non plus d’une simple sensibilité. Le SSD (en kg/cm²) des 9 points spécifiques bilatéraux est déterminé et un score myalgique s’établit par l’addition de ceux-ci. Un test-retest réalisé à 3 jours d’intervalle apprécie la reproductibilité intra-examinateur des SSD. Résultats : Les coefficients de variation correspondent respectivement à 17 % et 13 % chez les sujets contrôles féminins et masculins, et 24 % chez les fibromyalgiques. La reproductibilité apparaît la plus favorable pour les points « fessier » et « genou ». Les SSD s’avèrent significativement inférieurs chez les sujets contrôles féminins en comparaison des volontaires masculins (p < 0,01) et aucun effet de latéralité n’est constaté. Les SSD mesurés chez les fibromyalgiques demeurent systématiquement inférieurs (réduction de 60 %) à ceux de la population contrôle (p < 0,0001). Les SSD les plus faibles sont mesurés aux points « trapèze », « occiput », « cervical antérieur » et « 2ème côte » tant chez les sujets contrôles que fibromyalgiques. Le score myalgique atteint 20 + 7,4 kg/cm² et 49,9 kg/cm² respectivement chez les patients fibromyalgiques et chez les sujets contrôles féminins. Discussion : Une mesure dolorimétrique permet d’objectiver le SSD avec une reproductibilité satisfaisante. Ce travail démontre des valeurs de SSD particulièrement faibles chez les fibromyalgiques. De façon originale, nous objectivons, chez les sujets contrôles, particulièrement de sexe féminin, des SSD souvent inférieurs au seuil décrit par l’ACR (4 kg/cm²). Conclusion : L’établissement d’un score myalgique permet d’apprécier, à partir d’une mesure dolorimétrique, la sensibilité nociceptive et offre la possibilité d’un suivi longitudinal du patient en terme de douleur.

Thermal infrared (IR) lenses require efficient anti-reflection coating. Moth-eye (or egg-box) 2D subwavelength gratings have demonstrated their ability to reach a very high transmission for a wide wavelength and angular range. The use in thermal IR is simplified by the lower resolution for lithographic technology, compared to visible waveband. However, deeper structures must be engraved and lithography must be adapted to IR materials. In order to be cost-effective, the patterning must be produced by replication techniques, such as embossing. Our laboratory is now experimenting hot embossing of moth-eye patterns in chalcogenide substrates. In this paper, theoretical analysis, micro-lithographic technology and manufacturing processes are detailed. [less ▲]

Introduction : La fibromyalgie et la lombalgie constituent deux affections musculo-squelettiques chroniques présentant de nombreuses similitudes, comme la douleur, la régression des activités physiques quotidiennes ou encore la désinsertion sociale. L’objectif de ce travail était de comparer des patients fibromyalgiques et des patients souffrant de lombalgies chroniques en termes de qualités musculaires à partir de mesures de force et de fatigabilité musculaires. Patients et méthodes : Vingt sujets contrôles de sexe féminin, vingt patientes fibromyalgiques et vingt patientes souffrant de lombalgies chroniques sont inclus dans l’étude. Le protocole comporte une évaluation de la force maximale isocinétique des muscles fléchisseurs et extenseurs de genou. La résistance musculaire à la fatigue s’apprécie par l’enchaînement de 30 mouvements consécutifs de flexion-extension de genou à intensité maximale. Les perceptions douloureuses et de pénibilité de l’effort sont respectivement mesurées à partir des échelles visuelle analogique (EVA) et de Borg. En outre, l’anxiété et la dépression sont déterminées à partir de l’ « Hospital Anxiety and Depression Scale » (HAD). Résultats : L’ensemble des performances de force et de fatigabilité apparaissent inférieures chez les fibromyalgiques, en comparaison non seulement des sujets contrôles mais aussi des patientes lombalgiques. Ces dernières développent des performances identiques à celles de la population contrôle. Les scores douloureux (EVA) et de pénibilité de l’effort apparaissent pourtant significativement augmentés au sein de ces deux populations pathologiques. Les questionnaires d’anxiété et de dépression (HAD) révèlent des scores significativement supérieurs chez les fibromyalgiques. Discussion : Ces résultats illustrent un profil musculaire différent entre populations fibromyalgique et lombalgique. La réduction majeure des performances développées par les patientes fibromyalgiques peut être mise en relation avec l’état de déconditionnement, les scores d’anxiété et de dépression, la douleur diffuse et d’éventuels mécanismes d’inhibition musculaire. Contrairement à certaines données de la littérature, nous observons des performances musculaires des membres inférieurs relativement préservées chez les patientes lombalgiques. Conclusion : Au terme de cette étude comparative entre populations souffrant de douleurs chroniques, nous démontrons de faibles performances musculaires développées par les membres inférieurs chez les sujets fibromyalgiques. Une mesure des qualités musculaires rachidiennes peut s’avérer plus spécifique dans l’établissement du profil musculaire du lombalgique. [less ▲]

Objectif : Ce travail a pour objectif d’apprécier l’intérêt d’un programme de reconditionnement physique aérobie dans le traitement de la fibromyalgie. Patients et méthodes : Dix patientes fibromyalgiques, diagnostiquées selon les critères du Collège Américain de Rhumatologie (1990), réalisent trois séances hebdomadaires d’une durée d’une heure trente sur une période de 3 mois. Le programme de revalidation comporte principalement des activités musculaires aérobies (bicyclette ergométrique, tapis de marche, rameur et step), complétées par des étirements et de la relaxation. Les bénéfices éventuels sont objectivés à partir d’épreuves physiques maximales (isocinétisme) et sous-maximales (test de marche, bicyclette ergométrique, endurance musculaire statique), d’une évaluation du seuil de sensibilité douloureuse à l’aide d’un dolorimètre et de questionnaires de qualité de vie, de quantification de la fatigue et de satisfaction. En outre, les perceptions douloureuses et de pénibilité de l’effort sont respectivement quantifiées à partir des échelles visuelle analogique (EVA) et de Borg. Résultats : Au terme de cette revalidation, une amélioration significative de tous les paramètres physiques est objectivée. Les performances s’améliorent de 26 % lors de l’épreuve de force isocinétique maximale réalisée au niveau des muscles fléchisseurs et extenseurs de genou, de 43 % lors des épreuves isométriques sous-maximales prolongées, de 42 % lors de l’épreuve ergométrique et de 17 % lors de l’épreuve de marche. Ces bénéfices s’accompagnent d’une réduction systématique des perceptions douloureuses et de la difficulté de l’effort mais aussi d’un accroissement du seuil de sensibilité douloureuse. Les questionnaires de qualité de vie et de quantification de la fatigue confirment l’amélioration fonctionnelle. Le programme répond effectivement aux attentes des fibromyalgiques, comme le démontrent les scores du questionnaire de satisfaction. Discussion : Cette option thérapeutique de revalidation se justifie d’autant plus que la faiblesse des qualités musculaires du fibromyalgique a déjà été soulignée. Cette rééducation devrait idéalement se compléter par diverses interventions comme le soutien psychologique et les stratégies cognitivo-comportementales. Conclusion : Cette étude confirme l’intérêt d’un programme de revalidation musculaire progressive dans le cadre de la prise en charge rééducative de la fibromyalgie. Un tel programme réduit les répercussions physiques et psychologiques défavorables de l’affection. [less ▲]

When bulk RE-BCO superconductors are used as permanent magnets in engineering applications, they are likely to experience transient variations of the applied magnetic field. The resulting vortex motion may cause a significant temperature increase. As a consequence the initial trapped flux is reduced. In the present work, we first focus on the cause of a temperature increase. The temperature distribution within a superconducting finite cylinder subjected to an alternating magnetic field is theoretically predicted. Results are compared to experimental data obtained by two temperature sensors attached to a bulk YBCO pellet. Second, we consider curative methods for reducing the effect of heat flux on the temperature increase. Hall-probe mappings on YBCO samples maintained out of the thermal equilibrium are performed for two different morphologies : a plain single domain and a single domain with a regularly spaced hole array. The drilled single-domain displays a trapped induction which is weakly affected by the local heating while displaying a high trapped field. [less ▲]

The behaviour of the semi-solid material is complex to simulate and many approaches are proposed in the literature to represent it. In this work, different constitutive equations are studied: the classical Northon-Hoff law, Joly and Merhabian's one [1] and an innovative micromechanical model using homogenisation technique [2]. These constitutive equations have been implemented in the FE code Forge2 (R) to simulate simple forming tests, such as compression and direct extrusion. The load-displacement curves using the three constitutive equations are compared in order to estimate their capabilities. [less ▲]

Solar absorption measurements using Fourier transform infrared (FTIR) spectrometry carry information about the atmospheric abundances of many constituents, including information about their vertical distributions in the troposphere and the stratosphere. Such observations have regularly been made since many years as a contribution to the NDSC (Network for the Detection of Stratospheric Change). They are the only ground-based remote sensing observations available nowadays that carry information about key atmospheric trace species in the free troposphere, among which the most important greenhouse gases. The European UFTIR project (Time series of Upper Free Troposphere observations from a European ground-based FTIR network, http://www.nilu.no/uftir) has focused on maximizing the information content of FTIR long-term monitoring data of some direct and indirect greenhouse gases (CH4, N2O, O3,HCFC-22, and CO and C2H6, respectively). The UFTIR network includes six NDSC stations in Western Europe, covering the polar to subtropical regions. At several stations of the network, the observations span more than a decade. Existing spectral time series have been reanalyzed according to a common optimized retrieval strategy, in order to derive distinct tropospheric and stratospheric abundances of the abovementioned target gases. A bootstrap resampling method has been implemented to evaluate trends of the tropospheric and total burdens of the target gases, including their uncertainties. In parallel, simulations of the target time series have been made with the Oslo CTM2 model: comparisons between the model results and the observations provide valuable information to improve the model, and in particular, to optimize emission estimates that are used as inputs to the model simulations, and to explain the observed trends. The final results of the project will be presented, and ways to proceed will be discussed. [less ▲]

A high temperature superconducting magnetic energy storage device (SMES) has been realised using a 350 m-long BSCCO tape wound as a ''pancake'' coil. The coil is mounted on a cryocooler allowing temperatures down to 17.2 K to be achieved. The temperature dependence of coil electrical resistance R(T) shows a superconducting transition at T = 102.5 K. Measurements of the V(I) characteristics were performed at several temperatures between 17.2 K and 101.5 K to obtain the temperature dependence of the critical current (using a 1 uV/cm criterion). Critical currents were found to exceed 100 A for T < 30 K. An electronic DC-DC converter was built in order to control the energy flow in and out of the superconducting coil. The converter consists of a MOS transistor bridge switching at a 80 kHz frequency and controlled with standard Pulse Width Modulation (PWM) techniques. The system was tested using a 30 V squared wave power supply as bridge input voltage. The coil current, the bridge input and output voltages were recorded simultaneously. Using a 10 A setpoint current in the superconducting coil, the whole system (coil + DC-DC converter) can provide a stable output voltage showing uninterruptible power supply (UPS) capabilities over 1 s.

This paper addresses the problem of computing symbolically the set of reachable configurations of a linear hybrid automaton. A solution proposed in earlier work consists in exploring the reachable configurations using an acceleration operator for computing the iterated effect of selected control cycles. Unfortunately, this method imposes a periodicity requirement on the data transformations labeling these cycles, that is not always satisfied in practice. This happens in particular with the important subclass of timed automata, even though it is known that the paths of such automata have a periodic behavior. The goal of this paper is to broaden substantially the applicability of hybrid acceleration. This is done by introducing powerful reduction rules, aimed at translating hybrid data transformations into equivalent ones that satisfy the periodicity criterion. In particular, we show that these rules always succeed in the case of timed automata. This makes it possible to compute an exact symbolic representation of the set of reachable configurations of a linear hybrid automaton, with a guarantee of termination over the subclass of timed automata. Compared to other known solutions to this problem, our method is simpler, and applicable to a much larger class of systems. [less ▲]

Uncoupling proteins (UCPs) are mitochondrial inner membrane proteins sustaining an inducible proton conductance. They weaken the proton electrochemical gradient built up by the mitochondrial respiratory chain. Brown fat UCP1 sustains a free fatty acid (FA)-induced purine nucleotide (PN)-inhibited proton conductance. Inhibition of the proton conductance by PN has been considered as a diagnostic of UCP activity. However, conflicting results have been obtained in isolated mitochondria for UCP homologues (i.e., UCP2, UCP3, plant UCP, and protist UCP) where the FFA-activated proton conductance is poorly sensitive to PN under resting respiration conditions. Our recent work clearly indicates that the membranous coenzyme Q, through its redox state, represents a regulator of the inhibition by PN of FFA-activated UCP1 homologues under phosphorylating respiration conditions. Several physiological roles of UCPs have been suggested, including a control of the cellular energy balance as well as the preventive action against oxidative stress. In this paper, we discuss new information emerging from comparative proteomics about the impact of UCPs on mitochondrial physiology, when recombinant UCP1 is expressed in yeast and when UCP2 is over-expressed in hepatic mitochondria during steatosis [less ▲]

We address the topic of real-time analysis and recognition of silhouettes. The method that we propose first produces object features obtained by a new type of morphological operators, which can be seen as an extension of existing granulometric filters, and then insert them into a tailored classification scheme. Intuitively, given a binary segmented image, our operator produces the set of all the largest rectangles that can be wedged inside any connected component of the image. The latter are obtained by a standard background subtraction technique and morphological filtering. To classify connected components into one of the known object categories, the rectangles of a connected component are submitted to a machine learning algorithm called EXtremely RAndomized trees (Extra-trees). The machine learning algorithm is fed with a static database of silhouettes that contains both positive and negative instances. The whole process, including image processing and rectangle classification, is carried out in real-time. Finally we evaluate our approach on one of today's hot topics: the detection of human silhouettes. We discuss experimental results and show that our method is stable and computationally effective. Therefore, we assess that algorithms like ours introduce new ways for the detection of humans in video sequences. [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.
