For the hydrological modeling of forested watersheds, the understanding of the forest hydrodynamic is essential. This study focusses on the hydrology of a Belgian forested plot with high stoniness and steep slope. The soil water content is monitored at several positions on the toposequence and at different depth. During rain events, peak in soil water content are observed in different depth depending on the position along the toposequence. [less ▲]

Solar-like oscillations have now been characterized for a large number of stars, thanks to asteroseismic data obtained recently by space missions. This has led to the determination of the global and internal properties of these stars. In particular, core rotation rates have been obtained for red-giant stars, which is of prime importance to progress in the modelling of the dynamical processes at work in stellar interiors. In this presentation, we discuss which constraints can be brought by these asteroseismic measurements on stellar models that include rotational effects. Similarly to the solar case, we show that an efficient mechanism is required for the transport of angular momentum in the radiative zones of red giants. The efficiency of this transport process can be determined by asteroseismic observations of red-giant stars. [less ▲]

Science and technology require an intervention by the law, and law is called upon to intervene in front of their evolution, and to look for proper solutions of governance and rational responses to their risks. One of the main issues to be investigated from the legal viewpoint is represented by the ‘dual-use dilemma’ that arises both in ‘traditional’ and new areas of techno-sciences. Indeed, any kind of research has the potential to be used both for bad as well as for good purposes. Therefore, it is important to reflect upon the ways to control possibly dangerous research without preventing the progress from going further. Such ‘dual-use dilemma’, then, entails the study of one of the fundamental freedoms in the biolaw area: the freedom of scientific research, its limits, and relationship with other rights/needs/freedoms (such the need of security). This work focuses on two areas of the techno-scientific world. One is more ‘traditional’, i.e. nuclear science, in whose context the reflections on ‘dual-use’ were born and developed, and the other one is a new emerging technology, which is synthetic biology. The aim is to understand how the freedom of scientific research could be shaped in relationship with other rights/needs/interests for dealing with ‘dual-use’ issues in the aforementioned areas of science and technology.

This paper reports on a preliminary investigation into the elaboration, by the additive process known as laser cladding, of composite coatings with a matrix of stainless steel 316L reinforced with varying contents of tungsten (WC) or silicon carbides (SiC) particles. Laser cladding is characterised by ultra-fast solidification and cooling rates, thus giving rise to ultra-fine out-of-equilibrium microstructures and potentially enhanced mechanical properties. Both types of composite coatings – i.e. with SiC or WC ‒ are compared in terms of their microstructures and hardness. Special attention is given to the dissolution of the carbides particles and to interfacial reactions taking place between the particles and the metallic matrix. [less ▲]

Dans le premier cas, une démarche de recherche est entreprise en amont de la conception d’une formation. La deuxième configuration illustre une recherche scientifique appliquée à un dispositif d’intervention existant et qui vient en retour en modifier la logique. Pour la troisième, il s’agit d’une articulation continue entre recherche et formation s’alimentant mutuellement dans une logique de recherche-action.

Insults, gossip, and slander are the origin of many conflicts during the Ancien Régime. They are used to hurt someone’s honour or reputation, which are essential values to keeping good relationships in society. People need to defend their honour when they are injured. They can seek reparations by taking legal action or opting for infrajudicial practices, such as contacting a notary. This possibility has attracted too little attention from historians whereas notarial records are a massive source of information related to conflicts affecting people's daily lives. Indeed, during the eighteenth century, inhabitants of Liège contacted a notary in order to find an agreement, clear their name of an insult, or to write their version of an aggression. [less ▲]

L’aménagement transsexuel comme solution à l’adolescence La transsexualité est souvent banalisée par les médias, séduits par l’idée facile à vendre d’une âme sexuée, donc du drame de la possible inadéquation entre le sexe psychique et le sexe corporel. L’observation clinique rigoureuse de son élaboration plaide cependant pour une architecture complexe, résultant d’une dynamique subtile entre le psychisme, l’histoire et l’environnement. En effet, dans l’analyse d’un cas clinique, nous constatons que, face au risque de l’effondrement identitaire d’une structure fragile le Moi tente de se renforcer par l’organisation de mécanismes de défense qui élabore une nouvelle identité étayée sur un physique transité vers l’autre sexe. Si l’on analyse les interactions précoces sous l’angle de la formation de l’identité sexuelle, le noyau « genré » du Moi peut subir une double attaque, par manque d’identification au même et par attaque mortifère du différent. Le Moi se trouve ainsi délié et persécuté par des objets partiels ou peu introjectés. A l’adolescence, moment potentiellement traumatique de la sexuation, le jeune se trouve confronté à l’interrogation sur son identité sexuelle, et lorsque le noyau « genré » s’est précisément trouvé fragilisé, l’angoisse surgit, avec le risque d’une bascule psychotique. Dans ces cas extrêmes, la recherche d’une nouvelle enveloppe, remodelage de la peau, permet de contenir l’éclosion du courant psychotique grâce à la disponibilité permanente de l’incorporation du différent, identification certes coûteuse en ressources mais peut-être, à même d’éviter l’effondrement narcissique complet.

Introduction : Platelet-rich plasma injections are a recent treatment for chronic tendinopathies. However, this theraeutic remains controversed in litterature. Up to now, there is no prognosis factors identified to predict a good evolution after injection of PRP. Purpose: The aims of this study were to evaluate the effect of PRP injection followed by a standardized reeducation protocol among patients suffering from different tendinopathies and to determine the good prognosis factors, if any. Methods : 51 patients suffering from different tendinopathies and refractory to conventional physiotherapy were treated with a PRP injection. Prior to the injection, a blood sample was drawn and some biological parameters (glycemia, cholesterol level, …). A pain assessment was then made using a visual analog scale (VAS) and a pressure algometer. The same assessment was carried out after 6 weeks and 12 weeks when possible. Results : There is an overall significant improvement VAS score at the end of the 12 weeks follow- up. However, no correlation was found between the evolution of the clinical scores and the biological parameters measured. Discussion and Conclusions : A PRP injection followed by a program of eccentric rehabilitation positively affects the algo-functional scores of patients with tendinopathie who were refractory to conventional physiotherapy, whatever their initial biological parameters.

INTRODUCTION: Very strenuous exercises can be performed on an isokinetic dynamometer in order to evaluate the resistance to fatigue of different muscular groups. Good cardiac function is necessary in order to perform these very intensive exercises; otherwise an acute myocardial dysfunction could theoretically appear in predisposed patients. PURPOSE: Our study aimed to observe the cardiovascular impact (by biological point of view) of maximal intense isokinetic eccentric and concentric protocols performed by a population of sedentary young men. METHOD: Resting (T0) and post-exercise (just after (T1), 3 hours (T2) and 24 hours after the exercise (T3)) blood samples were taken in 2 populations of young sedentary men: 12 subjects (22.5±1.15 yo) for the eccentric protocol and 18 subjects (22.4±2.6 yo) for the concentric protocol. These subjects performed an intense maximal isokinetic exercise of the quadriceps muscles involving 30 knee flexions–extensions for each leg. We evaluated markers of cardiovascular risk (highly sensitive troponin T (hs-TnT), N-Terminal Brain natriuretic peptide (NT-proBNP), myoglobin (MYO)), of inflammation (highly sensitive C-reactive protein (hsCRP)), muscle damage (creatine kinase (CK)) and of oxidative stress (myeloperoxidase (MPO), lipidic peroxides (POXL), reduced (GSH) and oxidised glutathione (GSSG)). Haemodynamic parameters were measured continuously using a Portapres, and respiratory parameters were measured using a Sensormedics Vmax 29C. RESULTS: All the physiological parameters measured presented statistically significant changes. For the eccentric exercise, no significant modification in cardiac (NT-proBNP, hs-TNT) and inflammation (hsCRP) biomarkers was observed. However, a significant increase for CK (T3), MYO (T2), MPO (T1), POXL (T1), GSSG (T3) and ratio GSH/GSSG (T2-T3) was shown. For the concentric exercise, the results showed significant increases for the CK (T1-T2-T3), MYO (T1-T2), GSH/GSSG (T1). Evolutionary trends were also observed for the following biomarkers: NT-proBNP (T1-T2-T3), MPO (T2), and GSSG (T4). DISCUSSION and CONCLUSIONS: No modification in cardiac biomarkers was observed after the maximal eccentric isokinetic exercise but some variations can be observed for these biomarkers after the concentric exercise. However, these changes do not exceed the reference values in healthy subjects. We were thus able to prove that the exercise could be performed without any risk to cardiac function in young sedentary subjects. Nevertheless, a significant level of oxidative stress was induced by both exercises. [less ▲]

Introduction: Literature is scarce concerning the effectiveness of high dose radial extracorporeal shock wave therapy (ESWT). Therefore, the aim of this study was to investigate its effectiveness on pain, function and pressure pain threshold in patients with chronicplantar fasciitis (PF). Materials and Methods: Patients with a diagnosis of chronic (pain lasting for more than 3 months) uni- or bilateral PF with a history of failed conservative treatment were included. After a 6-week control period during which no treatment occurred, a 2-week treatment period followed by a three weeks of rest (cicatrization phase) was provided. The treatment period consisted of three radial ESWT sessions (2000 impulses of 10 Hz frequency per session with an energy flux density of 0,275mJ/mm2) separated by a one-weekinterval. Patient assessments (pain intensity, foot function and pressure pain threshold (PPT) at the site of maximum local tenderness disability) were conducted at baseline, after the 6-week control phase (pre-treatment) and at the end of the cicatrization phase (post-treatment). Results: Thirty patients (19 women (63.3%)) with chronic PF and a mean age of 51.9±11 years were included in the present study. No drop-out occurred throughout the study period. No changes were observed at the pre-treatment assessment session except for pain intensity which decreased slightly but significantly (P<0.05). At the post-treatment session, highly significant (P<0.001) and clinically meaningful changes occurred for pain intensity (-34%), foot function score (-60%) and PPT (+68%). Conclusions: The present study suggests that high dose radial ESWT is a feasible and effective way to quickly and significantly decrease pain and disability in most patients with chronic PF.

Intorduction: Some clinical series have evaluated the effect of platelet-rich plasma (PRP) in the treatment of jumper’s knee. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of 2 or 3 successive infiltrations. Purpose: The aim of this study was to evaluate whether 2 infiltrations of PRP proves more effective than a single treatment. Methods: Twenty patients suffering from chronic jumper’s knee were enrolled into the study and split into two randomized groups (1 or 2 infiltrations of PRP, respectively). The 3-month follow-up evaluation consisted of VAS, IKDC and VISA-P scores, along with algometer, isokinetic and ultrasounds evaluations. After 1 year, subjects were contacted to define their functional evolution. Results: The concentration of the PRP used for each infiltration was similar in both groups, and contained no red or white cells. Results revealed no difference in treatment efficacy between the groups. Discussion and Conclusion: The comparison between 1 or 2 infiltrations of PRP did not reveal any difference between the 2 groups at short to mid term. A second closely-timed infiltration of PRP to treat jumper’s knees is not necessary to improve the efficacy of this treatment in the short term. A second infiltration should perhaps be envisaged later, but this remains to be demonstrated. [less ▲]

Various methods are presently used to measure methane (CH4) emissions of ruminants on pasture. Those measurements are essential to evaluate nutritional strategies to mitigate enteric CH4 emissions as well as addressing the selection of low producing individuals. On pasture and in the barn, variations in CH4 emissions are observed depending on the time of the day. However, no studies have been made to link these diurnal fluctuations to behavioural phases, especially on pasture. The aim of this study was to understand the individual dynamics of CH4 production and their links to the grazing behaviour. For this purpose, a new tool was specifically developed. Five red-pied dry cows were equipped with infrared CH4 and carbon dioxide (CO2) sensors measuring concentrations in the exhaled air at 4 Hz. The animals were equipped with a heart rate belt (HR) and motion sensors to detect their feeding behaviours (grazing vs. rumination) for periods of 8 h/d. Wind speed (WS) was also monitor to verify interference with sampled gas concentrations. Results showed that using the CH4:CO2 ratio reduced the interference with WS that was observed on raw CH4 and CO2 concentration signals. CH4:CO2 ratio average over 5 min periods indicated that CH4 emissions were lower during grazing than rumination (P<0.01). The eructation frequency during grazing (0.48 eructation/min, P<0.01) was also lower than during rumination (0.65 eructation/min). HR was higher during grazing that rumination. Because HR is usually linked to metabolic CO2 production intensity, hence influencing the denominator of the CH4:CO2 ratio, further investigation should focus on the quantification of changes in fermentative and metabolic CO2 emissions along the day to estimate total CH4 production more accurately and the relationship between CH4 emissions patterns and post-feeding times.

TiO2 films with MWCNTs are produced for anticorrosive applications to increase the lifetime of steel materials. TiO2 has two additional properties, photoactivity and superhydrophilicity. Two TiO2 samples, synthesized in aqueous or alcoholic media, have been doped with MWCNTs. The material which best combines anticorrosive, superhydrophilic and photocatalytic properties, is the one produced in aqueous medium (Aq-TiO2-CNT). Doping with MWCNTs increases the photodegradation of p-nitrophenol from 18% to 50%. MWCNTs allow to reduce the corrosion current and the corrosion potential. The good superhydrophilicity of TiO2 is kept on stainless steel with a contact angle after illumination around 5°. [less ▲]

One of the major ecological research questions is understanding how biodiversity influences ecosystem functioning. Unravelling interspecific feeding preferences of organisms with overlapping trophic niches will give part of the answer. Subsequently, the present study displays the trophic diversity of a benthic copepod community in a North-Western Corsican Posidonia oceanica seagrass ecosystem. These seagrass meadows are often interrupted by bare sand patches serving as deposition area for loose detritus. The accumulated macrophytodetritus, mainly derived from senescent macrophytes, harbour a diverse community of Harpacticoida (Crustacea, Copepoda). The most abundant copepods (i.e. three harpacticoids and one calanoid, belonging to different eco-morphological types) and their potential food sources (i.e. macrophytodetritus, epiphytic biofilm and suspended organic matter) were analysed for stable isotope ratios (δ13C, δ15N) and total lipids content. The results revealed a harpacticoid copepod feeding preference towards the epiphytic biofilm, while calanoid copepods preferred suspended organic matter. Additionally, a species-specific composition variation revealed finer partitioning of food resources (e.g. different micro-organisms present in the biofilm like bacteria, diatoms, fungi) over time.In conclusion, results showed species-specific food preferences, resulting in trophic niche and resource partitioning. Every eco-morphological type seems to cope in different ways with temporal fluctuations of food sources to comply with their nutritional needs. This illustrates the high resilience of the copepod community present in macrophytodetritus accumulations. Moreover, our results underlined the importance of multiple biomarker species-specific analysis in trophic ecology studies, especially in complex and dynamic environments offering numerous food items to consumers.

Objective: People with accurate representations of their own cognitive functioning (i.e., cognitive self-awareness) tend to use appropriate strategies to regulate their behavior. Due to the lack of appropriate instruments, few studies have examined the development of this ability among children. Method: This study tested the measurement properties of the self-rating and other-rating forms of the Questionnaire of Executive Self-Awareness (QESA), designed to tap children’s knowledge of their executive functioning. Participants were 317 children aged 7 to 14 years old. Results: Confirmatory factor analyses carried out on the QESA confirmed the eight-factor structure of both versions. There were significant correlations between the QESA and the parent versions of the BRIEF, DEX-C, and CHEXI. Both forms of the QESA were able to distinguish between children who had sustained a traumatic brain injury (TBI) and control participants. A self-other discrepancy score was computed to assess children’s executive self-awareness. A statistical difference was observed between the TBI and control groups on this score, suggesting that TBI may trigger self-awareness impairments in children. Conclusion: The good psychometric properties of the two forms of the QESA were established. Furthermore, results of the analyses carried on the different discrepancy scores seem to indicate that the QESA could help clinicians to detect patients with self-awareness deficits. [less ▲]

At the end of 2013, a new Common Agricultural Policy was defined at the European level, including the implementation of the so-called “green payment”, which obliges farmers to respect three new conditions in order to get financial support through direct payments. The year 2015 being the first implementation year, the consequences on Walloon agriculture are examined. It appears that 50% of Walloon farmers are not obliged to practice crop diversification, while 16% are obliged to have at least two crops on their arable land and 33% are obliged to have at least three crops on their arable land. Less than 1% does not respect the new diversification rules. Concerning the obligation to have at least 5% of ecological focus area on the arable land, it appears that 54% of Walloon farmers are in conditions not to be obliged to respect the measure. When they implement the measure, the percentage of ecological focus areas in arable land reaches 6.9% as a mean and 2.4% do not reach the requested 5%. Finally, it can be said that the green payment does not represent a big constraint for Walloon farmers, though eventual economic consequences are still to be precised, while environmental benefits are strengthened.

Recent researches have stated the fast deployment of IPv6. It has been demonstrated that IPv6 grows much faster, being so more and more adopted by both Internet service providers but also by servers and end-hosts. In parallel, researches have been conducted to discover and assess the usage of MPLS tunnels. Indeed, recent developments in the ICMP protocol make certain categories of MPLS tunnels transparent to traceroute probing. However, these studies focus only on IPv4, where MPLS is strongly deployed. In this paper, we provide a first look at how MPLS is used under IPv6 networks using traceroute data collected by CAIDA. At first glance, we observe that the MPLS deployment and usage seem to greatly differ between IPv4 and IPv6, in particular in the way MPLS label stacks are used. While label stacks with at least two labels are marginal in IPv4 (and mostly correspond to a VPN usage), they are prevalent in IPv6. After a deeper analysis of the label stack typical content in IPv6, we show that such tunnels result from the use of 6PE. This is not really surprising since this mechanism was specifically designed to forward IPv6 traffic using MPLS tunnels through networks that are not fully IPv6 compliant. However, we show that it does not result from non dual-stack routers but rather from the absence of native IPv6 MPLS signaling protocols. Finally, we investigate a large Tier-1 network, Cogent, that stands out with an original set-up. [less ▲]

Bulk (RE)BCO superconductors are able to trap record magnetic fields and can be used as powerful permanent magnets in various engineering applications such as rotating machines and magnetic bearings. When such superconducting (SC) “trapped field magnets” are combined to a ferromagnetic (FM) disc, the total magnetic moment is increased with respect to that of the superconductor alone. In the present work, we study experimentally the magnetic behaviour of such hybrid FM/SC structures when they are subjected to cycles of applied field that are orthogonal to their permanent magnetization, i.e. a “crossed-field” configuration. Experimental results show that the usual “crossed-field demagnetization” caused by the cycles of transverse field is strongly reduced in the presence of the ferromagnet. [less ▲]

In view of its large gap, previously reported asymmetries and near-infrared (NIR) spiral arms, the transition disk of the Herbig Fe star HD 142527 constitutes a remarkable case study. Based on our ALMA observations of the disk and previous NIR images, we try to infer the origin of the observed spirals. Different scenarios, including the effect of the binary companion, unseen planets, disk self-gravity and tidal interaction by a stellar encounter, are discussed in order to constrain the origin of the spirals. We conclude that at least a combination of two of the considered scenarios are required to account for the large annular gap, the NIR spirals and all three CO spirals. [less ▲]

Different tools and methods have been proposed in the literature to assess the required flexibility resources and needs in a particular grid or geographical area. However, few of them are readily usable in long term energy planning models because they require small time steps and detailed data. In this paper, two candidate methods to address the flexibility issues in such models are evaluated. A unit commitment model developed at the JRC, DispaSET 2.0, is used as a test case for the different simplified flexibility assessment tools. The modelled geographical area is Belgium, using historical data for the demand and VRE curves and their day-ahead forecast. Different VRE penetration scenarios are simulated to evaluate the flexibility of the power system. The simplified assessment tools are then run with the same inputs. Results indicate significant discrepancies between the detailed Unit Commitment model and the simplified tools. The underlying reasons are described and suggestions are formulated to improve their accuracy. [less ▲]

Activity recommendation systems aims at providing relevant information depending on targeted users' groups. For instance in a city, it makes sense to differentiate local residents from tourists. This research investigates to what extent the anonymized data collected from social networks can be used as a basis for making activity recommendations associated with local residents versus tourists when visiting a public place, such as a museum or gallery. Using rules based on the spatial, temporal and semantics of visited places, we are able to infer if a user is likely to be local or a tourist, based on anonymous sample Foursquare data and place-based semantics retrieved using Google Places API. Using semantics of visited places, it becomes possible to infer additional information about a user based on their movements over space and time. Depending on the kind and frequency of visited places, inferences about the aim of a visit to a location are possible. This analysis could provide information to users in the form of recommendations based on their movements while travelling around an area. This study has been performed using Foursquare check-ins for visitors to the Art Institute of Chicago between March 2010 and January 2011. [less ▲]

We present results from two Pluto stellar occultations observed on 18 July 2012 and 04 May 2013, and monitored respectively from five and six sites in South America. Both campaigns involved large telescopes (including the 8.2-m VLT at ESO/Paranal). The high SNR ratios and multi-chord coverage provide amoung the best Pluto atmospheric profiles ever obtained from the ground.We show that a spherically symmetric, clear (no-haze) and pure N2 atmosphere with a unique temperature profile satisfactorily fits the twelve lightcurves provided by the two events. We find, however, a small but significant increase of pressure of 6% (6-sigma level) between the two dates, with values of 2.16 ± 0.2 and 2.30 ± 0.01 μbar at the reference radius 1275 km, respectively.We provide atmospheric constrains between 1190 km and 1450 km from Pluto's center, and we determine the temperature profile with accuracy of a few km in vertical scale. Our model shows a stratosphere with strong positive gradient between 1190 km (at 36 K, 11 μbar) and r =1215 km (6.0 μbar), where a temperature maximum of 110 K is reached. Above it is a mesosphere with negative thermal gradient of -0.2 K/km up to 1,390 km (0.25 μbar), at which point, the mesosphere connects itself to a more isothermal upper branch at 81 K. This profile provides (assuming no troposphere) a Pluto surface radius of 1190 ± 5 km, consistent with preliminary values obtained by New Horizons. Currently measured CO abundances are too low to explain the negative mesospheric thermal gradient. We explore the possibility of an HCN (recently detected by ALMA) cooling. This model, however, requires largely supersaturated HCN. Zonal winds and vertical compositional variations of the atmosphere are also unable to explain the observed mesospheric trend.These events are the last useful ground-based occultations recorded before the 29 June 2015 occultation observed from Australia and New Zealand, and before the NASA's New Horizons flyby of July 2015. This work can serve as a benchmark in the New Horizons context, enabling comparisons between ground-based and space results concerning Pluto's atmospheric structure and temporal evolution. [less ▲]

TRAPPIST is a 60-cm robotic telescope in La Silla Observatory [1] mainly dedicated to the study of exoplanets and comets. The telescope is equipped with a set of narrow band cometary filters designed by the NASA for the Hale-Bopp observing campaign [2]. Since its installation in 2010, we gathered a high quality and homogeneous data set of more than 30 bright comets observed with narrow band filters. Some comets were only observed for a few days but others have been observed weekly during several months on both sides of perihelion. From the images, we derived OH, NH, CN, C[SUB]2[/SUB], and C[SUB]3[/SUB] production rates using a Haser [3] model in addition to the Afρ parameter as a proxy for the dust production. We computed production rates ratios and the dust color for each comet to study their composition and followed the evolution of these ratios and colors with the heliocentric distance.The TRAPPIST data set, rich of more than 10000 images obtained and reduced in an homogeneous way, allows us to address several fundamental questions such as the pristine or evolutionary origin of composition differences among comets. The evolution of comet activity with the heliocentric distance, the differences between species, and from comet to comet, will be discussed. Finally, the first results about the one year campaign on comet C/2013 US10 (Catalina) and our recent work on the re-determination of Haser scalelengths will be presented.[1] Jehin et al., The Messenger, 145, 2-6, 2011[2] Farnham et al., Icarus, 147, 180-204, 2000[3] Haser, Bulletin de l’Académie Royal des Sciences de Belgique,63, 739, 1957 [less ▲]

Rosetta gets closer to the nucleus than any previous mission, and returns wonderfully detailed measurements from the heart of the comet, but at the cost of not seeing the large scale coma and tails. The ground-based campaign fills in the missing part of the picture, studying the comet at about 1000 km resolution, and following how the overall activity of the comet varies. These data provide context information for Rosetta, so changes in the inner coma seen by the spacecraft can be correlated with the phenomena observable in comets. This will not only help to complete our understanding of the activity of 67P, but also to allow us to compare it with other comets that are only observed from the ground.The ground-based campaign includes observations with nearly all major facilities world-wide. In 2014 the majority of data came from the ESO VLT, as the comet was still relatively faint and in Southern skies, but as it returns to visibility from Earth in 2015 it is considerably brighter, approaching its perihelion in August, and at Northern declinations. I will present results from the 2014 campaign, including visible wavelength photometry and spectroscopy, and the latest results from 2015 observations. [less ▲]

Volatile production rates, relative abundances, rotational temperatures, and spatial distributions in the coma were measured in C/2012 S1 (ISON) using long-slit high-dispersion (λ/Δλ ~ 25,000) infrared spectroscopy as part of a worldwide observing campaign. Spectra were obtained on UT 2013 October 26 and 28 with NIRSPEC at the W. M. Keck Observatory, and UT 2013 November 19 and 20 with CSHELL at the NASA IRTF. H[SUB]2[/SUB]O was detected on all dates, with production rates increasing by about a factor of 40 between October 26 (R[SUB]h[/SUB] = 1.12 AU) and November 20 (R[SUB]h[/SUB] = 0.43 AU). Short-term variability of H[SUB]2[/SUB]O was also seen as the production rate increased by nearly a factor of two during observations obtained over a period of about six hours on November 19. C[SUB]2[/SUB]H[SUB]6[/SUB], CH[SUB]3[/SUB]OH and CH[SUB]4[/SUB] abundances were slightly depleted relative to H[SUB]2[/SUB]O in ISON compared to mean values for comets measured at infrared wavelengths.

Usually temperatures at the molecular formation control the fractionation of the heavier element in molecular species, e.g., D-fractionation in water.In cometary volatiles, the [SUP]14[/SUP]N/[SUP]15[/SUP]N ratios in CN have been well observed (Manfroid et al. 2009, A&A, 503, 613, and reference therein) and is consistent with the ratio in HCN (a most probable parent of CN) measured in few comets (Bockelée-Morvan et al. 2008, ApJ, 679, L49). Those ratios are enriched compared to the proto-solar value by a factor of ~3. In contrast to those Nitriles, there are only few reports on [SUP]14[/SUP]N/[SUP]15[/SUP]N ratios in Ammonia (as Amine) (Rousselot et al. 2014, ApJ, 780, L17; Shinnaka et al. 2014, ApJ, 782, L16). Ammonia (NH[SUB]3[/SUB]) is usually the most abundant and HCN is the second most abundant N-bearing volatiles in cometary ice. Especially, recent observations of [SUP]15[/SUP]NH[SUB]2[/SUB] revealed the [SUP]14[/SUP]N/[SUP]15[/SUP]N ratios in NH[SUB]3[/SUB] are comparable to those of CN. However, from the viewpoint of theoretical work, the enrichment of [SUP]15[/SUP]N in cometary NH[SUB]3[/SUB] cannot be reproduced by current chemical network models. Information about the diversity of the [SUP]14[/SUP]N/[SUP]15[/SUP]N ratios in NH[SUB]3[/SUB] of individual comets is needed to understand the formation mechanisms/environments of NH[SUB]3[/SUB] in the early solar system.To clarify the diversity of the [SUP]14[/SUP]N/[SUP]15[/SUP]N ratios in cometary NH[SUB]3[/SUB], we determine the [SUP]14[/SUP]N/[SUP]15[/SUP]N ratios in NH[SUB]3[/SUB] for more than ten comets individually which include not only Oort cloud comets but also short period comets by using the high-resolution optical spectra of NH[SUB]2[/SUB]. These spectra were obtained with both the UVES mounted on the VLT in Chile and the HDS on the Subaru Telescope in Hawaii.The derived [SUP]14[/SUP]N/[SUP]15[/SUP]N ratios in NH[SUB]3[/SUB] for more than ten comets show high [SUP]15[/SUP]N-enrichment compared with the elemental abundances of nitrogen in the Sun by about factor of ~3 and has no large diversity depending on these dynamical properties. We discuss about the origin of the formation conditions of cometary NH[SUB]3[/SUB] and its physico-chemical evolution in the solar nebula based on our and other results.This work was supported by JSPS, 15J10864 (Y.

Chariklo is the largest Centaur object known to date, and it is surrounded by dense and narrow rings (Braga-Ribas et al. Nature 508, 72, 2014). The size, shape and orientation of the central body are important parameters to better understand the dynamics of the rings.In that context, we have analyzed three stellar occultations by Chariklo and its main ring observed on June 3, 2013, April 29, 2014 and June 28, 2014. Elliptical limb fitting to Chariklo’s main body occultation chords has been performed, where we denote a (resp. b) the semi-major (resp. semi-minor) axis of the limb. Preliminary results indicate that Chariklo’s limb is elliptical with axes ratio b/a~0.89. We obtain a~133 km and b~119 km, providing an equivalent radius of R[SUB]equiv[/SUB]=√(ab)~126 km. The rms dispersion of the fit, about 4 km, is compatible with local topographic features on a small icy body. For comparison, an equivalent radius of R[SUB]equiv[/SUB]= 119±5 km, based on thermal data, is given by Fornasier et al, AA 518, L11, 2014, while Duffard et al. AA 568, A79, 2014 estimate a= 122 km and b= 117 km.Our results are obtained under the simplifying assumption that the main ring is circular and that its center coincides with that of Chariklo. Caveats and error bars will be discussed, and dynamical implications will be presented. In particular, rough estimations of the ring apsidal precession rates will be given, as well as constraints on Chariklo's density. [less ▲]

Background: Mesenchymal stromal cell (MSC) have immunomodulating properties and could be used as immunosuppressive agents. We report the 6- month safety results for the 5 first patients treated with MSC after kidney transplantation (KTx). Here, we address 3 specific safety issues: immunization against MSC and engraftment syndrome defined as acute graft dysfunction not related to rejection and over-immunosuppression. Patients and method: MSC production was carried out locally. MSC were not matched with kidney recipients’ HLA. Included patients were non-immunized, first transplant recipients from deceased donors. MSC (1.5–3.0 9 106/kg) infusion was planned 3 to 5 days post KTx. Patients with cardiovascular instability post KTx were excluded. All patients were treated with Basiliximab induction, Tacrolimus, Mycophenolate Mofetil and Steroid. We prospectively screened for anti-HLA antibodies at month 1, 3 and 6. Informed consent was obtained from all participants. The local ethical committee approved the protocol. Results: Collectively there were 23/50 and 29/50 HLA mismatches (MM) with kidney and MSC donor respectively, out of which 5 were shared MM. One patient developed de novo DSA, 2 patients anti-HLA antibodies against shared kidney/MSC MM and 1 patient developed 2 specific antibodies against MSC (MSCSA) at month 6. All antibodies were anti HLA class I except for 1. We did not observe any “engraftment” syndrome. Three patients experienced non- severe opportunistic infections: 1 CMV reactivation and 2 polyoma-BK virus viremia.Conclusion: We did not observe any strong safety signal. We did however observe some degree of immunization in 3 patients: 2 developed antibodies against shared kidney/MSC donor HLA MM and 1 MSCSA. [less ▲]

Introduction: This study aimed to determine the most recent results of kidney transplantation (KT) from donation after brain death (DBD) and circulatory death (DCD). Primary endpoints were graft and patient survival, and graft function. Acute rejection and post-operative complications were assessed as secondary endpoints. Patient and Methods: This retrospective mono-center review consisted of 226 DBD- and 104 DCD-KT between 2008 and 2014. Results: Graft survival was comparable between two groups (95.1 vs. 91.1% at 1 year, 92.8 vs. 91.1% at 3 years and 89.2 vs. 91.1% at 5 years). 46% and 40% of graft loss were attributed to patient death with a functioning graft and rejection. Patient survival was comparable between 2 groups (97.8 vs. 95.1% at 1 year, 94.1 vs. 91.2% at 3 years, and 89.6 vs. 82.3% at five years). Etiology of patient death included cardiac arrest (16.7%), infection (16.7%), cancer (13.3%), and unknown cause (46.7%). Delayed graft function occurred in 14.6% of DBD- and 30.8% of DCD-KT (p = 0.001). Primary non function was encountered in 2.6% DBD- and 4.8% DCD-KT (p = ns). Graft function was worse in DCD than DBD up to 3 months post-transplant (p = 0.034), however, no difference existed afterwards. Biopsy-proven acute rejection was found in 12.8% and 13.5% of DBD- and DCD-KT during an average 3 months post- transplant (p = ns). This rate was 7.1% vs. 8.9% on surveillance biopsy performed between 3 and 6 months post-transplant (p = ns). Post-operativecomplication rate was comparable between 2 groups, concerning patient death, reoperation, transfusion, perirenal hematoma, macroscopic hematuria, urinary obstruction, wound problem, and infection. Nevertheless, contamination of preservation solution occurred more commonly in DCD than DBD (0.4% vs. 3.8%, p = 0.036). Conclusions: Despite worse early graft function, DCD-KT was not inferior to that originating from DBD up to 5 years post-transplant, therefore deserves to be used. [less ▲]

Background: Mesenchymal stromal cells (MSC) are multipotent bone mar- row progenitors that have demonstrated significant immunosuppressive effects in various in vivo and in vitro studies. This study aimed to be the first evaluation of the safety and tolerability of MSC infusion after liver transplantation in a prospective, controlled phase-1 study. Methods: 10 liver transplant recipients under standard immunosuppression (TAC-MMF-low dose steroids until day 30) received 1.5–3 9 106/kg third party MSC on post-operative day 3 ` 2. These patients were prospectively compared to a group of 10 control liver recipients. Primary endpoints were MSC infusion toxicity, and incidence of cancer and opportunistic infections at month 6. Secondary endpoints were patient and graft survivals and rejection at month 6, as well as the effects of MSC on recipients’ immune function and on immunohistology of at month 6 graft biopsies. Results: No MSC infusional toxicity was observed. Both groups were comparable in terms of donor and recipient characteristics. There was no difference in primary end-points between control and MSC groups. No patient developed de novo cancer. There was no statistical difference in patient and graft survivals or in rejection rates. There was no graft rejection in the MSC group. Month-6 graft biopsies were not different according to Banff and fibrosis scores. Discussion: This phase 1 study showed excellent tolerability and safety of a single infusion of third-party MSC after liver transplantation. There were no graft safety issues and no excess of immunosuppression after MSC injection. Further analyses of consequences of MSC injection on the immune profile are needed. The possibility of avoiding calcineurin-inhibitors with repeated MSC injections as main immunosuppressive therapy and/of tolerance induction by MSC infusion should be investigated by further studies. This study is in part supported by an ESOT Senior Clinical Research Grant and by the University of Liege. [less ▲]

Introduction: Comparable transplant outcomes between controlled donation after circulatory death (cDCD) and donation after brain death (DBD) kidney transplantation (KT) have been confirmed. However, few data describes the histology of cDCD-KT which is subjected to prolonged procurement warm ischemia. This study aimed to evaluate the rate of interstitial fibrosis (IF) and tubular atrophy (TA) on the surveillance biopsy performed in our unit between the 2 and 6 months post KT. Acute rejection was considered as secondary endpoint. Patients and Methods: 330 KT (226 DBD and 104 DCD) have been performed between 2008 and 2014. Surveillance or per-cause biopsy was performed in 272 recipients. Among them, the rate of adequate (≥8 glomeruli and ≥1 large-sized artery) was 76.8%. Results: IFTA was found in 11.5% and 25.7% of DBD and cDCD-KT, respectively (p = 0.004). Considering IF and TA separately, the corresponding rates were 20.4% vs 32% (p = 0.04) and 23% vs 36% (p = 0.03), respectively. If acute rejection before routine biopsy was excluded, either IF or TA rate was significantly higher in cDCD- than DBD-KT (12.6% vs 27.1%, p = 0.006; 17.6% vs 31.4%, p = 0.016; and 20.9% vs 35.7%, p = 0.015 in case of IF-TA, IF, and TA, respectively). A cDCD-KT compared to a DBD-KT was 3.11 (95%CI 1.51– 6.43, p = 0.002), 2.34 (95%CI 1.21–4.53, p = 0.011) and 2.29 (95%CI 1.23– 4.27, p = 0.009) times more likely to have IFTA, IF, and TA, respectively. Extended criteria donor (ECD) vs standard criteria donor (SCD) was also an independent risk factor for IFTA (OR = 3.11, 95%CI 1.51–6.43, p = 0.002), IF (OR = 4.86, 95%CI 1.96–12.05, p = 0.001), and TA (OR = 4.09, 95%CI 1.68– 9.93, p = 0.002). The rate of acute rejection diagnosed by SB was 7.1% and 8.9% in DBD and cDCD kidney grafts (p = ns), respectively.Conclusion: KT from cDCD increased the risk of IF-TA between 3 and 6 months post-transplant. Further studies are warranted to investigate the evolution of this phenomenon over time and its effect on graft function. [less ▲]

Euthanasia is since 2002 legalized in Belgium for adults under strict conditions. The patient must be in a medically futile condition, of constant and unbearable physical or mental suffering that cannot be alleviated, resulting from a serious and incurable disorder caused by illness. This implies that also non-terminal not-cancer patients can request for euthanasia for instance in case of debilitating neurological disorder. From 2005 till 2015 more than 25 patients, suffering from diverse neuropsychiatric diseases, got their request for euthanasia granted, and subsequently asked spontaneously for the possibility of organ donation. The involved physicians, the transplant teams and the Institutional Ethics Commit- tees, had the well-discussed opinion that this strong request for organ donation after euthanasia could not be denied. A clear separation between the euthanasia request, the euthanasia procedure and the organ procurement procedure was judged necessary. After extensive preparation, finally, in Belgium, 17 patients got their wish for organ donation after euthanasia fulfilled, in several academic or non-academic hospitals and in different regions. Several requests and preparations were started for other patients but ultimately did not lead to organ donation due to patients’ personal choices or logistically reasons. The euthanasia procedure was carried out by three physicians involved in the euthanasia granting. After clinical diagnosis of cardiac death, the procurement team came in and performed the organ procurement similar as in a DCD type III procedure. Almost always, liver, two kidneys and sometimes lungs and pancreatic islets were successfully recovered and transplanted, after allocation by Eurotransplant. The possibility of organ donation after their euthanasia provides a very much improved self-image of these patients, and adds something really positive to the unfortunate end-of-life of these patients.

Experimental models of renal ischemia/reperfusion (I/R) have suggested protective effects of mesenchymal stromal cells (MSC) therapy. Still, param- eters of MSC injection, including volume, route and timing of cell administration, remain largely debated. Particularly, MSC infusion in mouse has been shown to be beneficial “a priori” but deleterious “a posteriori” of renal I/R injury. In order to further investigate the influence of the timing of MSC administration, we used 10-week-old Lewis rats categorized in 4 groups. Groups 1 (MSC D-7, n = 10) and 2 (MSC D + 1, n = 7) received caudal i.v. injection of MSC (1.5 9 106 in 1 ml of saline) 7 days before or 1 day after renal I/R, respectively. Control groups 3 (saline D-7, n = 6) and 4 (saline D + 1, n = 6) received equal volume of saline at similar time points. Left renal ischemia (by clamping of the renal pedicle) lasted 45 min. Right nephrectomy was simultaneously performed. Blood sample was collected from inferior vena cava at 48 h post reperfusion. MSC phenotype was confirmed by FACS analysis. In groups 1 and 3, serum creatinine (SCr) reached 1.4 ` 0.7 versus 2.4 ` 0.8 mg/dl, respectively (p < 0.05). In groups 2 and 4, SCr was 4.9 ` 0.7 versus 3.3 ` 0.9 mg/dl, respectively (p < 0.001). Furthermore, SCr levels were statistically worse when MSC were administered after renal I/R in comparison to a priori infusion (p < 0.0001). In conclusion, MSC administration 7 days prior to renal I/R attenuates kidney injury in comparison to (i) saline infusion or (ii) MSC infusion 1 day after renal I/R. Conversely, on the basis of SCr levels, MSC therapy performed after renal I/R worsens kidney injury in rats. [less ▲]

Introduction: Liver transplantation (LT) can result in significant bleeding requiring transfusion of allogenic blood products, which potentially leads to postoperative morbidity and mortality (1). This study aimed to determine transfusion needs during LT in our institution and its preoperative predictive factors. Material and Methods: Two hundred LT performed at the CHU Liege between 2006 and 2012 were respectively reviewed (age = 55 ` 11 yo, BMI = 25.5 ` 4.4 kg/m2, F/M = 45/155, MELD score = 19 ` 10). Transfu- sion needs of the different blood products during POD 0, and POD 0–7 were recorded. Parameters associated with the transfusion of more than 2 units of RBC (p ≤ 0.1) were identified using the Kruskal Wallis and chi square tests (table 1). These parameters were then placed into a backward stepwise logistic regression model for the transfusion of more than two units of RBC at POD 0. A p value threshold ≥0.1 was used for leaving the model. Results: Transfusion needs were: RBC = 2[0–4], FFP = 4[2–7], PLT = 1[0– 1] during POD 0; and RBC = 3[0–6], FFP = 6[3–10], PLT = 1[0–2] during POD 0–7. Preoperative factors independently associated with the transfusion of more than two units of RBC were preop Hb (0.6 [0.46–0.79], p < 0.001) and MELD score (1.13 [1.06–1.20], p < 0.001). Discussion: These results suggest that preop Hb and MELD score are associated with blood requirements during LT. [less ▲]
