We report on methane (CH4) dynamics in landfast sea ice, brine and under-ice seawater at Barrow in 2009. The CH4 concentrations in under-ice water ranged between 25.9 and 116.4 nmol L-1sw, indicating a supersaturation of 700 to 3100 % relative to the atmosphere. In comparison, the CH4 concentrations in sea ice, ranged between 3.4 and 17.2 nmol L-1ice, and the deduced CH4 concentrations in brine, between 13.2 and 677.7 nmol L-1brine. We investigated on the processes explaining the difference in CH4 concentrations between sea ice, brine and the under-ice water, and suggest that biological controls on the storage of CH4 in ice was minor in comparison to the physical controls. Two physical processes regulated the storage of CH4 in our landfast ice samples: bubble formation within the ice and sea ice permeability. Gas bubble formation from solubility changes had favoured the accumulation of CH4 in the ice at the beginning of ice growth. CH4 retention in sea ice was then twice as efficient as that of salt; this also explains the overall higher CH4 concentrations in brine than in the under-ice water. As sea ice thickened, gas bubble formation became less efficient, CH4 was then mainly trapped in the dissolved state. The increase of sea ice permeability during ice melt marked the end of CH4 storage. [less ▲]

: Suite aux récents bouleversements économiques et sociaux touchant les pays de l’Union Européenne, de nombreux partenariats entre services publics d’emploi et agences d’emploi privées se sont développés et complexifiés, suivant une logique de gestion mixte du marché de l’emploi. Cette communication porte sur l’étude d’un partenariat public-privé entre un service public régional belge et un organisme de formation. À partir des apports conceptuels et théoriques de la sociologie de l’action publique et de la littérature propre aux agences d’emploi privées et aux partenariats public-privé, nous analyserons la capacité d’un dispositif public à assurer la remise à l’emploi de son public-cible. Pour ce faire, nous étudierons son rôle et ses effets sur les trajectoires professionnelles des demandeurs d’emploi y recourant. [less ▲]

Au cours de ces dernières années, le souci d’allier flexibilité et sécurité au travail a conduit à l’essor considérable des métiers de l’intermédiation (Orianne et Maroy, 2008). En particulier dans le domaine de l’accompagnement et du développement de carrière, divers dispositifs privés d’aide et de suivi ont vu le jour afin de contribuer à l’amélioration des conditions de travail et d’assister les travailleurs dans leurs transitions professionnelles. Par leur action, ces nouveaux dispositifs n’hésitent pas à complexifier les temporalités sociales en créant de nouvelles opportunités d’emploi et en redéfinissant les rythmes de carrière. À l’aide d’une étude de cas dans le secteur du recrutement belge, nous analyserons la capacité d’un processus de mise en emploi à remplir de tels objectifs dans un contexte de gestion mixte du marché du travail. Approchée d’une manière qualitative (entretiens semi-directifs et observations), nous étudierons l’apport de cette agence de placement au travers d’un cadre théorique qui intègre les concepts de dispositif (Foucault, 1977 ; Peeters et Charlier, 1999 ; Raffnsoe, 2008) et de réseaux sociaux (Grossetti 2005, 2008 et 2011). Nous montrerons qu’un plus de régir l’offre et la demande de travail, ce dispositif d’intermédiation, par son système de cooptation et son accompagnement de carrière, assure la fluidification du marché et sécurise la dynamique des transitions professionnelles.

Belgian rivers are fragmented by numerous obstacles which considerably limit the free access of fish to functional habitats. Fish-passes are major tools used to increase stream continuity and improve connectivity in the upstream direction. Using two modern multispecies fish-passes, this study aims to investigate multiyear abundance of holobiotic potamodromous fish and their seasonal movement patterns in relation with environmental factors. The fish passes were monitored continuously during 5 and 7 years and are located in two Belgian streams: the (19.3m³.s-1) and the Berwinne (1.9m³.s-1). Results revealed the presence of 20 different fish species, 14 species in the Berwinne and 19 species in the occurrence, salmonids and cyprinids species were predominant. A great interspecific and intraspecific variability in capture periodicity and in terms of stimulation by combination of factor environmental was observed. This study highlights the complexity and the omnipresence of holobiotic potamodromous fish movements at different life stages, in medium size river and brings new information on fish passes efficiency and use by these poorly known species.

Background: 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) may be considered as a recent therapeutic option for chronic tendinopathies. The aim of the current study is to evaluate the clinical status and the return to sports activities in patients with chronic upper patellar tendinopathies up to 1 year after 1 infiltration of PRP. Methods: Twenty patients with chronic upper patellar tendinopathy were enrolled. Assessments were made before infiltration of PRP, and 6 weeks and 3 months and 1 year after the infiltration, using a 10-point Visual Analogic Scale and algofunctional scores (IKDC and VISA-P). Moreover, they had to answer an information questionnaire concerning their life and sports activities. 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. VAS has significantly dropped, IKDC and VISA-P significantly improved over the follow-up of 1 year. Seventy percents of patients reported a favourable evolution with decrease of pain, 15% did never report any improvement and 15% were treated surgically. Seventy percents returned to sports activities, 64,3% without any pain, and 50% of them recovered the same sport level. Younger patients seemed to be more susceptible to have an improvement of pain by the PRP infiltration. Conclusions: This study demonstrates that a local infiltration of PRP associated with a submaximal eccentric protocol can improve, at 1 year, symptoms of chronic jumper’s knee in patients non-responsive to classical conservative treatments.

BACKGROUND: Troponin measurement is the gold standard for diagnosis of Acute Myocardial Infarction (AMI). Troponin (highly sensitive (hs), T or I) is measured by immunochemistry instrument or by Point of Care (POCT). POCT can be useful in emergency lab or ward for a faster diagnosis of patients with chest pain. Our study compared analytical performance of a POCT AQT90 Flex (Radiometer Medical) (AQT) and TnThs Cobas 8000 (Roche Diagnostics) (Cobas). We also compared the clinical performance of both methods at recommended cut-off (14 ng/L for Cobas and 30 ng/ L for AQT). METHODS: We selected 104 patients (296 samples) (range: 6-13822 ng/L) admitted in the Emergency ward for which at least 1 troponin determination (Cobas 8000) had been re-quested in the past 24 hours according to rule in/out procedure applied by this ward. Samples were then measured with the AQT. Inter-assay CV was maximum 8.6% and 9.6% for Cobas and AQT respectively. The cut-off defined as the 99th percentile for Roche was 14 ng/L and the recommended decision threshold value was 30 ng/L for Radiometer. Retrospective analysis of final diagnostic was obtained for all participants: we considered as “true positive” patients for whom a final diagnostic was ST segment-Elevation Myocardial Infarction (STEMI) or non STEMI (NSTEMI). RESULTS: On the whole range of measure, the 2 methods showed a good correlation (r2=0.98). Regression equation was Cobas = 0.98 AQT + 31 ng/L (95%CI of the intercept: (26.7;37.7) and 95% CI of the slope (0.96;1)). When we stratified, for the values <54 ng/L, the equation became Cobas = 0.52 AQT +1.1 ng/L (95%CI of the intercept: (-4.8;5.5) and 95% CI of the slope (0.39;0.69)). Bland and Altman plot did not show any bias. At admission [2-7 hours], 78 (81%) of admitted patients were finally considered as AMI, sensitivity was 92 % [96%] for Cobas and 78% [91%] for AQT. Specificity was 15% for Cobas (cut-off 14ng/L) or 73% (cut-off 54 ng/L) and 76% for AQT. CONCLUSIONS: Overall, there was a good correlation between the 2 methods. However, using a cut-off of 14 ng/L for Cobas is questionable for a rule in/out procedure in an emergency ward. Using 54 ng/L for Roche and 30 ng/L for AQT would have led to the best discrimination between patients presenting AMI or not. [less ▲]

BACKGROUND: Cortisol measurement is useful in evaluation of Cushing syndrome, adrenal insufficiency, mineralocorticoid excess and congenital adrenal hyperplasia. We developed a liquid chromatography–tandem mass spectrometry (LCMS/MS) method for salivary and urinary cortisol and we determined the 95th percentile (p95) for the urinary and salivary cortisol. We compared them to the Mayo Clinic expected values. METHODS: Saliva at 8 am and 11 pm and 24h urine were obtained from 32 healthy (22 female, 34.3±9.3 yo) volunteers. We performed validation with the enoval software (Arlenda, Belgium). For the validation, we used water or urine with spiked known amounts of cortisol for the CORS and CTU respectively. For the CORS, samples were centrifuged, deuterium labelled cortisol was added as internal standard and the protein precipated by acetonitril. The supernatant was evaporated, dissolved in methanol acidified with acetic acid and analyzed by LCMS/MS. For CTU, samples were centrifuged, deuterium labelled cortisol was added as internal standard and diluted by the ammonium acetate and analyzed by LCMS/MS. At the Mayo Clinic, the expected values were 1-7.5 μg/L (7 a.m-9 a.m) and <1 μg/L (11-12 p.m) for CORS and 3.5-45 μg/24h (<18yo) for CTU. RESULTS: For the CTU, the with-in run did not exceed 3% (0.4-3%) and the between-run did not exceed 3.1% (0.4-3.1%) for 1.5-750 μg/L. The limit of quantification was 1.5 μg/L. The linearity was good between 1.5 and 750 μg/L. The recovery is 97.9±2.2% (95%CI for the mean: 92.4-101.1%). For the CORS, the with-in run and between run did not exceed 8% (1.9-8%) for 1.15-8.65 μg/L. The limit of quantification was 1.15 μg/L. The analyse presents a good linearity between 1.15 and 8.65 μg/L. The recovery is 99.9±2.9% (95%CI for the mean: 94.2-108.7%). The p95 for the CTU according to the CLSI C28-A3 was 33 μg/24h, and for the CORS was 5.42 μg/L at 8 am and 0.7 μg/L at 12 pm. CONCLUSIONS: Our developed method in liquid chromatography tandem mass spectrometry was validated for the measurement of urinary and salivary cortisol. Our findings indicate that the proposed analytical methods were suitable for routine purposes and useful in many pathological conditions.The expected values confirm these defined by the Mayo Clinic.

Il concerne plus spécifiquement l’article 138bis-4 de la loi belge, lequel règlemente les hausses tarifaires des contrats d’assurance maladie non liés à l’activité professionnelle. Dans un souci de protection du consommateur, le législateur a, en effet, choisi d’encadrer strictement les possibilités de hausses tarifaires de ce type de contrat. Interrogée à titre préjudiciel, la Cour est appelée à se prononcer sur la compatibilité de ce mécanisme avec le droit de l'Union. [less ▲]

In this work, we propose a simple yet effective solution to the problem of connectome inference in calcium imaging data. The proposed algorithm consists of two steps. First, processing the raw signals to detect neural peak activities. Second, inferring the degree of association between neurons from partial correlation statistics. This paper summarises the methodology that led us to win the Connectomics Challenge, proposes a simplified version of our method, and finally compares our results with respect to other inference methods.
