Introduction: Exertional myopathies are a common cause of exercise intolerance in the equine athlete, and Polysaccharide Storage Myopathy (PSSM) is a widely described muscular disease. It is characterized by an accumulation of abnormal glycogen in myofibers due to a genetic defect in the skeletal muscle glycogen synthase (GYS1) enzyme. We hypothesized that energy production through oxidative phosphorylation (OXPHOS) in muscular mitochondria might be impaired in type-1 PSSM-affected horses. Methods: Eight horses with a history of exertional rhabdomyolysis were tested for the GYS1 mutation. Muscle biopsies were collected and used for histological analysis and high resolution respirometry (HRR). HRR values from 3 groups of horses (5 PSSM-positive horses, 3 horses with a history of myopathy but PSSM-negative and 16 healthy controls) were compared using a linear mixed model to take into account repeated (2–3 times) measurements made for each horse. Results: In 5/8 horses histology revealed an accumulation of abnormal glycogen in myofibers. These 5 horses also tested positive for the GYS1 mutation. A severe depression of maximal OXPHOS capacitywas observed by HRR in 7/8 horses with exertional rhabdomyolysis, with lower values in PSSM-positive cases (4/5). Conclusions: Our study shows a severely decreased OXPHOS capacity in PSSM-affected horses. PSSM is considered primarily a defect in glycogen synthesis but altered OXPHOS might play a central role in its pathogenesis. [less ▲]

Understanding the formation of sdB stars is one of the remaining challenges of stellar evolution theory. Competing scenarios have been proposed to account for the existence of such evolved objects. They give quite different mass distributions for resulting sdB stars. Detailed asteroseismic analyses, including mass estimates, of 15 pulsating hot B subdwarfs have been published in the past decade. Masses have also been reliably determined by light curve modeling and spectroscopy for 7 sdB components of eclipsing or reflection binaries. We present here the empirical mass distribution of sdB stars on the basis of these samples. Implications are also briefly discussed. [less ▲]

Depuis une décennie, les découvertes de matériaux colorants se multiplient parmi les sites dont les occupations remontent au Paléolithique moyen et au Paléolithique supérieur ancien. L’intérêt qu’elles suscitent tient à ce qu’elles sont susceptibles de révéler des pratiques techniques diverses et complexes, mais il tient aussi à leur forte potentialité à traduire des pratiques symboliques du fait de leur pouvoir colorant intense et des couleurs exploitées : le rouge et le noir. C’est sur le gisement châtelperronien de la grotte du Renne à Arcy-sur-Cure (Yonne), fouillé de 1949 à 1963 par André Leroi-Gourhan, qu'environ 2000 matières colorantes découvertes ont conduit à échafauder des théories concernant leurs transformations et leurs utilisations qui méritaient d’être éprouvées. Il est supposé, depuis leur découverte, qu’elles ont fait l’objet d’un chauffage contrôlé qui visait à en modifier la couleur, le chauffage permettant de transformer les matières colorantes jaunes (hydroxydes de fer) en orangé, en rouge et en violacé (oxydes de fer). De cette hypothèse découle la théorie selon laquelle les Néandertaliens ont exploité les matières colorantes en tant que pigment pour des réalisations symboliques, voire d’ordre esthétique, ce qui n’a pas encore pu être prouvé. La présente étude, fondée sur le croisement des données issues des analyses de la nature physico-chimique et pétrographique des assemblages de matières colorantes, mais aussi sur leur intégration dans le gisement, en association avec des structures d’habitat dont la conservation est exceptionnelle, et sur une série d’expérimentations visant à caractériser les poudres obtenues par différents moyens a permis de définir les choix techniques qui ont présidé à l’approvisionnement en matières colorantes dans tous les niveaux d’occupation châtelperroniens de la grotte du Renne. Il a ainsi été possible de démontrer qu’aucune des matières colorantes, rouges ou noires, n’a fait l’objet d’un chauffage préalablement à son utilisation, bien au contraire de ce qui avait été supposé jusqu’ici. Ces matières colorantes ont fait l’objet d’un approvisionnement raisonné auprès de formations géologiques affleurant ponctuellement. L’exploitation de ces gîtes de matières premières colorantes a été la même durant toute la séquence châtelperronienne et s’est orientée préférentiellement vers des matériaux que l’on peut aisément réduire en poudre. L’assemblage des matières colorantes de la grotte du Renne révèle à la fois une permanence des pratiques techniques et culturelles qui ont trait à l’emploi de matières colorantes et un profond ancrage des connaissances et de la compréhension des multiples propriétés et qualités de ces matériaux intensément mises à profit dans des activités diverses, domestiques, artisanales et manifestement aussi d’ordre symbolique, de telle sorte que le gisement châtelperronien était tout de rouge et noir.

In this study, samples of stainless steel AISI 316L have been processed by selective laser melting, a layer-by-layer near-net-shape process allowing for an economic production of complex parts. The resulting microstructures have been characterised in details in order to reach a better understanding of the solidification and consolidation processes. The influence of the processing parameters on the mechanical properties was investigated by means of uniaxial tensile testing performed on samples produced with different main orientations with respect to the building direction. A strong anisotropy of the mechanical behaviour was thus interpreted in relation with the microstructures and the processing conditions. [less ▲]

Objectifs Les médecins généralistes (MG) jouent un rôle majeur dans la détection et la gestion des abus de substances. L’étude présentée ici investiguait les facteurs qui influencent leur implication concernant la gestion des abus d’alcool, des drogues illégales, des hypnotiques et des anxiolytiques dans la population belge des 18-65 ans. Méthodes 20 MG ont été interrogés par entretiens semi-directifs dans les régions de Liège et d’Anvers. Le I-Change Model de de Vries a été utilisé pour construire le guide d’entretien et analyser les données récoltées. Résultats Parmi les principaux résultats de l’étude, il ressortait que les MG étaient fortement influencés dans leur approche par leurs propres représentations de l’abus, qui oscillait leurs responsabilités professionnelles envers ces patients et la responsabilité de ces derniers quant à la gestion de leur santé, avec l’idée de faute morale en substrat. En ce sens, l’abus de substance était perçu sur un continuum entre l’abus comme forme de maladie chronique d’une part, et la faute morale d’autre part. L’alcool et le cannabis étaient néanmoins mieux acceptés socialement que les autres substances. Les propres expériences personnelles des MG concernant les abus avaient aussi une incidence sur leur volonté de s’investir avec ces patients. Pour autant, les pratiques multidisciplinaires (notamment au forfait) et l’expérience étaient évoqués comme des facteurs importants quant à l’engagement dans la gestion. Les contraintes temporelles et l’investissement demandé étaient, en revanche, considérés comme des barrières. Conclusion Les facteurs motivationnels apparaissaient centraux dans la décision de s’investir dans la gestion des abus de substances, bien davantage que les connaissances théoriques et les formations qui semblaient plus secondaires. La peur du burn-out s’exprimait donc en substrat. La formation des MG devrait tenir compte de ce souhait de se protéger, afin de favoriser simultanément une approche centrée sur le patient. [less ▲]

This work applies a “product-oriented engineering” approach to the development of porous scaffolds for tissue engineering. Polylactic acid scaffolds were obtained by a freeze-drying process. Their 2D/3D microstructure was characterized by X-ray microtomography and related to the operating conditions used. Two types of scaffold end-use properties were characterized in relation to their microstructure: the mechanical and the transport properties. Scaffold young's modulus was computed from data measured on tension-compression devices. To evaluate the permeability, Darcy’s experiments were carried out. The obtained results allowed highlighting the quantitative relationships existing between elaboration conditions, microstructure and end-use properties of the fabricated PLA scaffolds. © 2014 International Society for Industrial Process Tomography.

Nuclear forward scattering by 125Te is a viable alternative to conventional 125Te Mössbauer spectroscopy avoiding all source related issues. Using reference compounds with known hyperfine parameters and Te oxides exhibiting stereochemically active lone pairs, we show that nuclear forward scattering by 125Te can be reliably used to extract quadrupole splitting energy and relative isomer shift. The rough correlation between Te-Ocoordination and quadrupole splitting energy as put forward by Takeda and Greenwood (J. Chem. Soc. Dalton, 2207, 1975), is corroborated by the presented results. © 2014 Springer Science+Business Media Dordrecht. [less ▲]

We present the preliminary seismic modeling of one of the hottest and most compact subdwarf pulsators, PB 8783 (EO Ceti). This is a well observed hot subdwarf star, including a 78 d campaign in white light photometry that we carried out at Mount Bigelow, Arizona, during the fall 2007. PB 8783 has also been observed at length in spectroscopy, revealing a spectrum highly contaminated by a main sequence companion. It is extremely difficult to disentangle the contribution of the two components and, as a consequence of this, the exact nature of the hot subdwarf (sdB or sdO star) is undetermined. We propose here to test the two hypotheses by asteroseismology. Although the sdB possibility cannot be excluded, the pulsation modes observed in PB 8783 are much better accommodated in the case of an sdO star. [less ▲]

The NECLIME database gathers data of the fossil flora recorded at many localities around the world at different times of the Miocene. François et al. (Palaeogeography, Palaeoclimatology, Palaeoecology, 304, 359–378, 2011) have presented a new method for evaluating palaeoclimate model simulations from such fossil floras. In this method, palaeovegetation is simulated from climate model outputs, using a dynamic vegetation model. Model vegetation reconstruction is then compared to the vegetation cover indicated by the fossil flora record at the various localities, using a common classification of plant functional types (PFTs) in the data and the model. Here, we apply this method to test several published Middle Miocene climate simulations conducted with General Circulation Models of different complexity: (a) Planet Simulator, (b) FOAM-LMDZ4, (c) MPI-ESM, (d) CCSM3.0 and (4) CESM1.0. Corresponding palaeovegetation distributions are simulated with the CARAIB dynamic vegetation model, in which an upgraded vegetation classification involving 26 PFTs has been imple- mented. The NECLIME palaeoflora data from 154 localities distributed worldwide have been translated in terms of the presence/absence of these PFTs. A comparison of models and data is then undertaken globally and in selected regions of the world, using all available localities. The level of agreement varies among models, among PFTs and among regions. For instance, some models are able to produce tropical and subtropical PFTs in Europe consistently with the data, but the agreement for these PFTs may be much poorer in other parts of the world, such as in northeastern Eurasia.

The toxicity of Fyto11, a plant resistance elicitor commercial formulation used to increase the natural resistance of Cucurbitaceae (cucumber, zucchini and melon) and Solanaceae (tomato and sweet pepper) against powdery mildew under greenhouse conditions, has been assessed on several beneficial arthropods: the honeybee Apis mellifera, the predatory miteTyphlodromus pyri, the aphid parasitic wasp Aphidius rhopalosiphi and the aphid predator Episyrphus balteatus. Tested at 0.5% and 1.0% spray dilution on plants, Fyto11 did not lead to significant corrected mortalities for E. balteatus larvae and adult wasps of A. rhopalosiphi, with a maximum of 5.4% mortality. No effects on reproduction capacity of the parasitic wasps were observed. The exposure of T. pyri protonymphs to Fyto11 on glass plates lead to corrected mortalities of 1.1% and 32.6% at 0.5% and 1.0% and to a reduction of female fertility of 9.0% and 25.4%, compared to the control performance. When assessed on the honeybee by contact and oral exposure, Fyto11 did not lead to significant effects, with LD50 estimated as > 10 μg a.i./bee (oral) and 12.5 μg a.i./bee (contact), leading to HQ ratio < 50 and classifying the product at no or low risk for honeybees. These results showed that the product was harmless for all beneficials at the proposed commercial rate, except for T. pyri at 1.0% on glass plates, where the product was rated as slightly harmful. Even if all the beneficial species’ diversity has not been assessed with this product, negative effects on non-target organisms are not expected in field conditions and Fyto11 can be considered as compatible with IPM programs.

Les nouvelles "Holunderblüte" (1863) de Wilhelm Raabe et "Ein Bekenntnis" (1887) de Theodor Storm allient psychologie, maladie et narration. Les deux textes racontent l’histoire de médecins qui à la fin de leur vie se questionnent sur leur propre responsabité dans un épisode du passé qui changea définitivement le cours de leur existence: la maladie et la mort de l’être qui leur était le plus cher (une jeune fille chez Raabe, l’épouse chez Storm). Par rapport aux études psychanalytiques très nombreuses dans la recherche sur Storm, cette étude souhaite montrer que la profondeur psychologique des textes doit être décrite par une analyse tenant compte du rôle anthropologique de la narration. Au niveau des narrateurs, la narration a ainsi une valeur curative pour ces deux médecins souffrant de sentiments de culpabilité et souhaitant retracer leur vie comme un sentier linéaire, cohérent et imbibé de sens. Les fonctions anthropologiques de la narration (production de sens, réduction de la contingence et de l’angoisse) auxquelles font appel ces individus sont toutefois relativisées par les textes eux-mêmes qui par leur forme et par le motif du labyrinthe évoquent l’aléatoire, la contingence et l’absence de sens.

The growing demand for air conditioning has caused a significant increase in demand for energy resources. The traditional commercial, non natural working fluids, like CFC, HCFC and HFC result in both ozone depletion and global warming emission of CO2. The use of hygroscopic salts in direct contact with moist air provides an attractive alternative to conventional cooling systems. The liquid desiccant can substitute the dangerous fluids. The main operations in Liquid Desiccant Cooling System (LDCS) are dehumidification and regeneration. This paper presents an experimental study of dehumidification/regeneration processes using LiBr as liquid desiccant in direct contact with the air at different operating conditions. An analysis of the mass transfer is made in order to prove is this material is the best liquid desiccant for LDCS. Experimental results showed the effect of air conditions on mass transfer. It can be seen that LiBr is able to absorb moisture and can be regenerated at low temperature. © 2014 Published by Elsevier B.V. [less ▲]

The work presents a sol-gel approach with two types of solvents for ZnO films deposition in view of varying the films' structural and optical properties. The ZnO films were characterized by X-Ray diffraction (XRD) and found to have a polycrystalline wurtzite phase structure. The grain sizes and the lattice parameters were determined; it was established that the ZnO crystallites' size increases with the annealing temperatures from 25 nm to 36 nm. The ZnO films possess high transmittance in the visible spectral range. Further, the optical band gap values were estimated. The material's vibration properties were analyzed by Fourier Transform Infrared (FTIR) spectroscopy. The two technological sol-gel approaches for deposition of ZnO films, using two different solvents, proved to be successful in producing structures with different structural and optical properties. The thin films fabricated were very smooth and uniform and exhibited a high transparency in the visible spectral range. [less ▲]

Accurate determination of optimal Nitrogen (N) recommendations which ensure maximization of farmer's revenue while minimizing the environmental constraint is maybe among the major challenges in agriculture. Crop models have the potential to deal with such aspects and could thus be used to develop decision support systems. However unknown future weather conditions remains the key point of accurate yield forecast. This paper presents the results of a preliminary study that aims to supply the unknown future with stochastically generated climatic conditions. Coupling the methodology with appropriate decision rules led to a generic decision support system able to guide the N management practices. [less ▲]

CoRoT and Kepler observations of red giants reveal rich spectra of non-radial solar-like oscillations allowing to probe their internal structure. An important question comes from the observation of mixed modes : When during the star’s ascension on the RGB are mixed-modes more likely to be detectable ? We follow the evolution of a star on the RGB and investigate the effect of its ascension on theoretical power spectrum. Equilibrium models (computed with the code ATON) represent four different stages of a star on the RGB. The mass of the star (1.5M") is in the typical mass range of stars observed by CoRoT and Kepler. We used a non-radial non-adiabatic code to compute the theoretical solar-like oscillations of these models. An important output of these calculations is the theoretical lifetimes of the modes. Then we computed the oscillation amplitudes through a stochastic excitation model. These computations allow us to draw theoretical power spectrum and discuss the possibility to observe mixed-modes at different evolutionary stages on the RGB. We found that structure modifications in a star ascending the RGB have an important impact on theoretical power spectrum of solar-like oscillations. Efficiencies of trapping and lifetimes of mixed modes are indeed strongly affected by this evolution. [less ▲]

Observations from space with CoRoT and Kepler have revealed the rich pulsation spectra that characterize the long period hot B subdwarf (sdB) pulsators of the V1093 Her type. These evolved and compact helium core burning stars can develop low amplitude oscillations with periods in the range ∼ 1 − 4 hours that correspond to low degree, mid to high order g-modes. These modes have the property to penetrate deep inside the star, down to the boundary of the central convective core. They are consequently particularly interesting as asteroseismic probes. Here we briefly review how the g-modes behave in sdB stars, focusing in particular on the seismic signatures coming from the core itself. We also briefly summarize the first seismic results obtained from space data in pioneering efforts to exploit the potential of long period sdB pulsators as deep probes of the core structure.

Introduction: Donation after circulatory death (DCD) donors have been proposed to partially overcome the organ donor shortage. DCD-LT remains controversial, with reported increased risk of ischemic cholangiopathy leading to graft loss. The authors retrospectively reviewed a single centre experience with DCD-LT in a 9-year period. Patients and Methods: 70 DCD-LT were performed from 2003 to November 2012. All DCD procedures were performed in operative rooms. Median donor age was 59 years. Most grafts were flushed with HTK solution. Allocation was centre-based. Median total DCD warm ischemia was 19.5 min. Mean follow-up was 36 months. No patient was lost to follow-up. Results: Median MELD score at LT was 15. Median cold ischemia was 235 min. Median peak AST was 1,162 U/L. Median peak bilirubin was 31.2 mg/dL. Patient and graft survivals were 92.8% and 91.3% at one year and 79% and 77.7% at 3 years, respectively. One graft was lost due to hepatic artery thrombosis. No PNF or graft loss due to ischemic cholangiopathy was observed in this series. Causes of death were malignancies in 8 cases. Discussion: In this series, DCD LT appears to provide results equal to classical LT. Short cold ischemia and recipient selection with low MELD score may be the keys to good results in DCD LT, in terms of graft survival and avoidance of ischemic cholangiopathy. [less ▲]

The global description of a nonlinear system through the linear Koopman operator leads to an efficient approach to global stability analysis. In the context of stability analysis, not much attention has been paid to the use of spectral properties of the operator. This paper provides new results on the relationship between the global stability properties of the system and the spectral properties of the Koopman operator. In particular, the results show that specific eigenfunctions capture the system stability and can be used to recover known notions of classical stability theory (e.g. Lyapunov functions, contracting metrics). Finally, a numerical method is proposed for the global stability analysis of a fixed point and is illustrated with several examples. [less ▲]

Background: Donation after circulatory death (DCD) donors > 55 years are usually not considered suitable for liver transplantation (LT). At our institute, age is not an absolute exclusion criterion to refuse DCD liver grafts. We retrospectively compared the transplant outcome of patients receiving older DCD liver grafts to the younger ones. Methods: 70 DCD liver transplants have been performed from 2003 to 2012, which includes 32 liver grafts from younger donors <55y (group A), 20 between 56 and 69 years (group B), and 18 from older donors ≥70 years (group C). The three groups were compared in terms of donor and recipient demographics, procurement and transplantation conditions, peak laboratory values during the first post-transplant week and results at one and three years. Results are expressed as median IQR. Results: No difference other than age in donor and recipient characteristics as well as procurement conditions was noted between both groups. Median donor age of the group A was 44 (38-45) years, in group B 62 (60-64) years and 73 (71-75) in group C. Median primary warm ischemia time (WIT) were 20 (17-22), 21 (19-25) and 19 (16-23) min, respectively (NS). Median cold ischemia time (CIT) was 236 (229-294), 245 (227-290) and 210 (195-277) min, respectively (NS). Peak AST (UI/ml) was 1162 (1072-3971), 1416 (1006-2752), and 1067 (902-4037), respectively (NS). There was no primary nonfunction and one patient needed retransplantation for artery thrombosis. Biliary complications occurred similarly in both groups, without graft loss secondary to ischemic cholangiopathy. Graft and patient survivals were not different at one and three years. Conclusion: This study shows comparable results between DCD liver transplants from younger and older donors. Therefore donor age >55 years should not be a contraindication to DCD liver transplantation if other donor risk factors (such as WIT, CIT) are minimized. [less ▲]

Une des missions fondamentales d’une formation universitaire est de permettre aux futurs professionnels d’identifier et de traiter efficacement les informations nécessaires aux prises de décisions parmi un nombre toujours croissant de documents disponibles. Pour atteindre cet objectif, le recours à l’Evidence-Based Practice (EBP) s’avère une approche méthodologique permettant d’acquérir les savoirs et savoir-faire requis pour, notamment, la recherche d’informations probantes. L’EBP doit donc logiquement faire partie de la formation initiale des futurs orthophonistes en restant en adéquation avec les besoins et pratiques des professionnels. À cette fin, il est important d’identifier les questions que se posent les cliniciens dans leur pratique quotidienne, la manière dont ils trouvent des réponses et s’ils ont recours ou non aux données issues de la recherche scientifique. Une enquête a été lancée en mai 2012 auprès d’orthophonistes travaillant en Communauté française de Belgique.

The determination of the location of the theoretical ZZ Ceti instability strip in the log g − Teff diagram has remained a challenge over the years, due to the lack of a suitable treatment for convection in these stars. We report here a detailed stability survey over the whole ZZ Ceti regime, including the very low masses where three pulsators have recently been found. We computed to this aim 29 evolutionary sequences of DA models with various masses and chemical layering. These models are characterized by the so-called ML2/α=1.0 convective efficiency and take into account the important feedback effect of convection on the atmospheric structure. We pulsated these models with the Liege nonadiabatic pulsation code MAD, which is the only one to conveniently incorporate a full time-dependent convection treatment and, thus, provides the best available description of the blue edge of the instability strip. On the other hand, given the failure of all nonadiabatic codes to account properly for the red edge of the strip, including MAD, we tested the idea that the red edge is due to energy leakage through the atmosphere. Using this approach, we found that our theoretical ZZ Ceti instability strip accounts remarkably well for the boundaries of the empirical strip. [less ▲]

We present a brief summary of what is currently known about white dwarf stars, with an emphasis on their evolutionary and internal properties. As is well known, white dwarfs represent the end products of stellar evolution for the vast majority of stars and, as such, bear the signatures of past events (such as mass-loss, mixing phases, loss and redistribution of angular momentum, and thermonuclear burning) that are of essential importance in the evolution of stars in general. In addition, white dwarf stars represent ideal testbeds for our understanding of matter under extreme conditions, and work on their constitutive physics (neutrino production rates, conductive and radiative opacities, interior liquid and solid equations of state, partially ionized and partially degenerate envelope equations of state, diffusion coefficients, line broadening mechanisms) is still being actively pursued. Given a set of constitutive physics, cooling white dwarfs can be used advantageously as cosmochronometers. Moreover, the field has been blessed by the existence of four distinct families of pulsating white dwarfs, each mapping a different evolutionary phase, and this allows the application of the asteroseismological method to probe and test their internal structure and evolutionary state.

Background: There is a controversy on the possibility to increase the organ donor pool by donation-after-circulatory-death (DCD) and the possible decrease in donation-after-brain-death (DBD) by DCD programs. Our aim is to report the DCD experience at the University Hospital of Liege, Belgium, from 2002 through 2012, in a donor region of about 1 million inhabitants. Methods: The prospective organ donor and recipient databases were retrospectively reviewed. Results: 94 and 331 procurements were performed from controlled DCD and DBD donors in the time period, respectively. DCD donors contributed to 22.1% of the deceased donor (DD) organ procurement activity from Jan 2002 to Dec 2012, and up to one-third annually since 2009. DCD liver and kidneys contributed 23.7% and 24.2% of the DD liver and kidney transplantation activity, respectively. There was no decrease of the DBD procurement in the study period. In 2012, overall 54 DD were procured in the Liege region, reaching a high procurement activity.Conclusions: Controlled DCD donors are a valuable source of transplantable liver and kidney grafts, and in our experience do not adversely affect DBD organ procurement activity.

The mixed symmetric positive and negative parity baryons are described in a similar way in the $1/N_c$ expansion method of QCD by using a procedure where the permutation symmetry is incorporated exactly.

Objectives: To investigate the epidemiological determinants responsible for the high number of anthropophilic dermatophytes received by the National Reference Center for Mycosis of Liege (NRCL) during the year 2012. To perform a genotypic characterization by the Diversilab® system focusing on the two main isolated species, Microsporum audouinii and Trichophyton violaceum. To present a preliminary study preceding the national survey launched in 2013. Methods: A total of 51 strains of M. audouinii (50 clinical + 1 reference (ref.) strains) and 15 strains of T. violaceum (14 clinical + 1 ref. strain) originating from different locations through Belgium were included in the study. The fungal strains were first cultivated on Malt agar, then sub-cultured in Sabouraud liquid medium (Fluka). The grown mycelium was processed for DNA extraction following recommendations of the manufacturer (Ultra Clean® DNA Microbial isolation kit, MoBio laboratories). Genotypic analysis was performed using the DiversiLab® system (BioMérieux) for DNA fingerprinting and analysis. Results: Regarding M. audouinii, four different genotypic groups of strains were separated. Group 1 includes 11 strains and is only found in the Liège surroundings. Group 2 includes only one strain with little differences compared to group 1 and collected from the Liège area. These two groups may be related to each other. Group 3 contains 36 strains and the reference strain. This genotype is distributed in different Belgium locations. The last group, group 4, contains only 3 isolates sharing low similarities in comparison with the 3 other groups. Concerning T. violaceum, 6 different genotypic groups with a mixed geographical distribution were determined. Group 1 includes 8 clinical isolates and the ref. strain. The other five isolates are all different and seem not to be related to each other. Conclusion: The automated typing DiversiLab® system proved to be an easy and efficient method to investigate the molecular epidemiology of dermatophytes infections. Preliminary results of the study show that, through Belgium, several groups of isolates co-exist for M. audouinii and T. violaceum providing evidence of genetic heterogeneity. This variation can be related to acquired mutations due to environmental adaptation. Further investigations are necessary to better understand the impact of this genotypic variation. [less ▲]

The determination of nitrogen isotopic ratios in solar system objects is important for a good understanding of their origin. The measurements of [SUB]14[/SUB]N/[SUB]15[/SUB]N isotopic ratio done so far in various solar system objects and molecules have revealed a great diversity (from 50 to 441), all of them, except Jupiter, being enriched in [SUB]15[/SUB]N compared to the protosolar nebula. Different explanations have been proposed to explain this enrichement. One of them suggests that these differences reflect the different interstellar N reservoirs from which N-bearing molecules are originating (Hily-Blant et al., 2013). These authors, from observations of H[SUB]13[/SUB]CN and HC[SUB]15[/SUB]N in two prestellar cores, suggest that the molecules carrying the nitrile- (-CN) functional group would be more enriched in [SUB]15[/SUB]N than the molecules carrying the amine (-NH) functional group. Comets are interesting targets to test this theory because they contain both HCN and NH[SUP]3[/SUP] molecules. So far the [SUB]14[/SUB]N/[SUB]15[/SUB]N ratio has only been measured in CN (Arpigny et al., 2003; Manfroid et al., 2009) and HCN (Bockelée-Morvan et al., 2005, 2008) in comets, leading for both species to [SUB]14[/SUB]N/[SUB]15[/SUB]N ≈ 150. Our work aimed at measuring the [SUB]14[/SUB]N/[SUB]15[/SUB]N isotopic ratio in NH[SUP]2[/SUP], which comes from NH[SUP]3[/SUP]. We have determined accurately the wavelengths of [SUB]15[/SUB]NH[SUP]2[/SUP] emission lines with the AILES beamline spectrometer at synchrotron SOLEIL by Fourier transform spectroscopy. The analysis of this spectrum has permitted to extract the [SUB]15[/SUB]NH[SUP]2[/SUP] emission lines wavelengths and to search for [SUB]15[/SUB]NH[SUP]2[/SUP] cometary emission lines. Thanks to a collection of spectra of 12 different comets obtained from 2002 to 2011 with the UVES spectrometer at the VLT ESO 8-m telescope (Manfroid et al., 2009), it has been possible to search for [SUB]15[/SUB]NH[SUP]2[/SUP] emission lines with a high sensitivity.

Oxygen is an important element in the chemistry of the solar system objects given its abundance and its presence in many molecules including H2O 80% of cometary ices). The analysis of oxygen atoms in comets can provide information not only on the comets themselves but also on the solar system. These atoms have been analyzed using the 3 forbidden oxygen lines [OI] observed in emission in the optical region at 5577.339 Å (the green line), 6300.304 Å and 6363.776 Å (the red lines) (Swings, 1962). Our analysis is based on a sample of 12 comets of various origins. The observing material is made of 53 high signal-to-noise spectra obtained with the high-resolution UVES spectrograph at the ESO VLT from 2002 to 2012 (Manfroid et al, 2009). After noticing that the green line is blended with one C2 line, we built synthetic spectra of C2 for each observing circumstances and we subtracted its contribution to the cometary spectra in order to ensure the decontamination of the 5577 Å line. Then, we measured the intensity of the 3 [OI] lines at different heliocentric distances. By comparing the green to red lines ratio (G/R) with the Bhardwaj & Raghuram (2012) effective excitation rates, we found that H2O is the main parent molecule when the comet is observed at 1 au. When the comet is located beyond 2.5 au from the Sun, CO2 also contributes to the production of oxygen. Studying forbidden oxygen lines could be a new way to estimate the abundances of CO2 in comets, a very difficult task from the ground (Decock et al. 2013). In order to estimate the effect of the quenching on our results, we analyzed the evolution of the G/R ratio at different nucleocentric distances. For nearby comets, we divided the extended 2D spectrum into several zones in order to analyze the oxygen lines as close as possible to the nucleus (down to ~10 km for the closest comets). Their analysis will allow us to study the link of the oxygen lines with the nucleocentric distance. We found a clear variation of the G/R ratio close to the comet nucleus that is in agreement with a contribution from CO2 as predicted by Raghuram & Bhardwaj (2013). [less ▲]

On May 4 2013, Pluto passed in front of a 14 star and the shadow was well observed from multiple occultation groups. This paper presents results from the three light curves observed at Las Cumbres Observatory Global Telescope Network (LCOGT) from their Cerro Tololo site. The three LCOGT telescopes have 1.0 m apertures and used identical frame-transfer cameras. The cameras currently have a 2 second readout time therefore autonomous observations were scheduled with different exposure times to give good time resolution of the event. We will present results of this occultation and compare occultation results from 1988 to 2013 with volatile transport models. [less ▲]

We performed high-dispersion near-infrared spectroscopic observations of comet C/2010 G2 (Hill) at 2.5 AU from the Sun using NIRSPEC (R ~ 2.5x10^4) at the Keck II telescope on UT 2012 Jan 9 and 10. The comet had been in outburst. Over the two nights of our observations, prominent emission lines of CH4 and C2H6 along with weaker emission lines of H2O, HCN, CH3OH and CO were detected. The gas production rate of CO was comparable to that of H2O. The mixing ratios of CO, HCN, CH4, C2H6, and CH3OH with respect to H2O are higher than those for normal comets by a factor of five or more. Hyper-volatile species such as CO and CH4 were enriched in the coma of comet Hill suggesting that the sublimation of these hyper-volatiles could sustain the outburst of the comet. Based on a comparison with optical observations, some fraction of water in the inner coma existed as icy grains. Those icy ice grains were likely ejected from nucleus by the sublimation of hyper-volatiles. [less ▲]

Objective: Jumper’s knee is a frequent chronic overuse syndrome of the upper part of the patellar tendon. Platelets contain lots of growth factors which could enhance the healing process of tendons. Infiltration of platelet-rich plasma (PRP) could be a new therapy for such chronic tendinopathies. Materiel and methods: Twenty patients with chronic upper patellar tendinopathy were enrolled. Assessments were made before infiltration of PRP, and 6 weeks and 3 months after the infiltration, using a 10-point Visual Analogic Scale, clinical examinations with a pressure algometer, algofunctional scores (IKDC and VISA-P), functional assessments (isokinetic and optojump evaluations) and imagery (ultrasounds and MRI). The PRP was obtained with an apheresis system (COM.TEC, Fresenius). Six millilitres of PRP were injected without local anaesthetic. One week after infiltration, patients started a standardised sub-maximal eccentric reeducation. Results: Pain during daily activities significantly decreased with time (especially after 6 weeks and continued to a lesser extend up to 3 months). During functional evaluation, it decreased as well, but without significant functional improvement. No improvements in the imagery measurements were observed. Younger patients seemed to be more susceptible to have an improvement of pain by the PRP infiltration. Discussion: This study demonstrates that a local infiltration of PRP associated with a submaximal eccentric protocol is efficient to improve symptoms of chronic jumper’s knee in patients non-responsive to classical conservative treatments.

Objectives.– To assess the feasibility and the effects of a strengthening program for people with Parkinson's disease (PD). Methods.– Fourteen patients with Hoehn and Yahr stage [1] < III of PD were allocated to either 24 sessions of strength training (ST group; n = 8) or to a control group (C group; n = 6) for 3 months. Concentric knee muscle strength and a maximal cycling incremental test were performed at baseline and after training. Training consisted of progressive resistive exercises on leg press, leg extension, leg curl, between 50 and 80% of 1RM and was completed by non-instrumented exercises for trunk and upper limbs muscles. Anxiety, depression and quality of life were assessed using questionnaires. An Anova for repeated measures was used for statistical analysis. Results.– Six patients of the ST group (75%) fully completed the program. There were significant “group by time” effects for all knee muscles strength measures of less involved side (P < 0.05). A significant “group by time” effect was also found for knee flexors of the most involved side, but only at angular speed of 180°/s (P = 0.03). Patients of ST group also increased maximal aerobic power (+13%) whereas patients of C group decreased their performances (–9%; “group by time” effect, P = 0.04). No changes in anxiety, depression or quality of life could be highlighted. Conclusions.– The increase of some strength measures in ST group showed that progressive strength training counteracts strength decrease among people with Parkinson's disease. Strengthening also had a positive effect on maximal aerobic power. [less ▲]

Introduction : Infiltrations of plasma rich platelets (PRP) represent a new treatment of tendinopathies. Currently, no side effects were reported in this indication. Case report: We report the case of a 35-year-old type 1 diabetic patient with right upper patellar tendinopathy that had persisted for more than 6 months. The patient benefited from an intratendinous infiltration of 6 mL of PRP (8.105 platelets/mm3, almost no red or white blood cells) after a carefully disinfection but without local anesthesia. Typically, a standardized program of sub-maximal eccentric rehabilitation should be started 1 week after infiltration. However, the patient experienced local swelling with erythema, increased heating and pain, which appeared just underneath the patella, without biological inflammatory syndrome. In absence of septic general symptoms, no blood or wound culture were made. At 2 weeks post-infiltration, a greatly increased Doppler signal in a thicker tendon was observed by ultrasounds compared to that before infiltration, but there was no sign of infection demonstrated by either MRI or CT. However, the local inflammation did not decrease after a 3-week treatment of local cryotherapy, local and oral NSAID, and adjunct use of colchicine 1 mg. Thus, an insidious infection was suspected, even though there was no evidence of biological inflammatory syndrome or sign of infectious lesion on imagery examination. Antibiotic therapy (rifampicine 600 mg + minocycline 100 mg), was initiated for three months. Due to a lack of improvement via imaging and clinical examination, a 3-phase bone scintigraphy was performed. The results suggested the presence of a complex regional pain syndrome type 1. The patient benefited from classical physical therapy and concomitant pain killers. The evolution was favorable after 6 months of treatment. Discussion : Even though PRP infiltration represents a new and promising treatment for tendinopathy, more studies are needed both to verify its clinical efficacy. Moreover, implementing this innovative treatment requires caution because of potential adverse events. Thus, the balance between benefits and risks must be carefully evaluated before using this treatment, especially in patients with type 1 diabetes. [less ▲]

“Conventional” treatments of tendinopathies are generally employed empirically to fight pain and inflammation but they do not modify the histological structure of the tendon. However, these treatments are not completely satisfactory and the recurrence of symptoms is common. In contrast to the passive pattern of many therapies dedicated to tendon disorders, some authors have promoted an eccentric training mode. Such active eccentric training programs are aimed at thwarting an aetiopathogenic theory proposing insufficient tensile strength of the tendon exposed to external loads which could progressively damage it. Though the literature remains incomplete on tendon architecture remodelling and real histological adaptations following an adapted eccentric training, clinical results following such therapy appear promising. Due to its noninvasiveness, low complication rate and high applicability combined with good results, extracorporeal shock wave therapy has become a well known option within the therapeutic spectrum for many tendinopathies. More specifically, it has been successfully applied in chronic tendinopathy resistant to a conservative training program including eccentric exercises. Platelets release different cytokines and growth factors that could promote angiogenesis, tissue remodelling (bone, skin etc.), and wound healing. Platelet-rich plasma (PRP) is obtained by centrifuging autologous blood to have a high concentration of platelets depending on the isolation method. For this reason, different PRP preparation techniques cannot provide a consistently identical final product, but there is currently no international consensus on this issue. Despite the proven efficacy of PRP tissue regeneration in labs, there is currently little tangible clinical evidence for chronic tendon disorders. The few studies that have been performed appear unlikely to be comparable. Up to now, randomised controlled studies with appropriate placebo groups are needed to determine the real effectiveness of PRP for treating chronic tendon conditions. However, this therapeutic option remains very popular in sports, and many top athletes are using it in case of musculoskeletal conditions. What is more, it has been removed from the doping lost of the World AntiDoping Agency. Other new therapeutic options (infiltrations of polidocanol, hyaluronic acid, botulinum toxin, patches of derivatives Nitro...) for treating tendinopathies are also discussed in this review.

En Belgique, l’implémentation des procédures préventives reste insuffisante dans plusieurs domaines, avec un gradient socio-économique défavorable aux moins nantis. Une implication accrue des médecins généralistes pourrait améliorer ces deux aspects, grâce à leur proximité avec les bénéficiaires potentiels. L’opinion des généralistes belges sur un investissement accru en prévention a été évaluée au moyen d’une échelle d’attitude construite au départ de verbatims provenant d’une enquête qualitative préalable. L’échelle a exploré 5 axes : vision globale de la santé, gestion collective des patients, évaluation de processus, collaboration et santé publique. Un questionnaire postal a été envoyé à 2.500 généralistes, dont 457 ont répondu valablement. L’axe gestion collective a obtenu la moyenne des scores d’attitude favorable à la prévention la plus élevée (77%), devant les axes santé globale (76%), évaluation (72%), collaboration (69%) et santé publique (63%). L’analyse factorielle a révélé deux facteurs principaux, l’organisation de la pratique (62% de la variance) et la formalisation (14% de la variance). L’organisation de la pratique (gestion des échéances, des données, pro-activité, sentiment de responsabilité envers la patientèle) était le facteur principal et était lié surtout aux associations et groupes pluridisciplinaires. La formalisation (codification précise de la pratique, assortie ou non d’une évaluation) venait ensuite et expliquait les plus fortes différences entre praticiens et entre communautés linguistiques. Les meilleurs scores étaient liés à une moindre ancienneté (<20 ans de pratique), aux associations et à la pratique urbaine. Le sexe du médecin ou le fait de travailler dans une structure préventive comme la protection maternelle et infantile étaient sans effet significatif. L’organisation de la prévention dépend des gouvernements de Flandre et de Wallonie-Bruxelles, mais des facteurs personnels et organisationnels propres aux généralistes doivent être considérés pour expliquer les résultats actuels. Une diffusion plus large et équitable des actes préventifs passe par la prise en compte de ces facteurs. [less ▲]
