ABSTRACT Background: Right ventricular remodeling due to pulmonary stenosis increases morbidity in children. Its pathophysiology needs to be clarified. METHODS: Six newborn lambs underwent pulmonary arterial banding, seven sham operation. mRNA encoding for cytokines, growth factors and regulators of apoptosis was sequentially measured in myocardium and blood before and up to 12 weeks postoperatively. RESULTS: Experimental animals showed hypertrophy and fibrosis of the right ventricular myocardium, myocardial over-expression of CT-1-mRNA and higher blood concentrations of mRNA encoding for VEGF, TGF-beta, Bak and BcL-xL than controls, respectively. CONCLUSION: Neonatal pulmonary stenosis leads to myocardial hypertrophy that is associated with CT-1 gene expression and with activation of growth- and apoptosis pathways in blood cells. [less ▲]

The equilibrium and metastable configurations of confined binary liquids has been a topic of research since the early work of Liu et al. in the nineties [1]. In particular, it has been proposed theoretically that liquids may coexist inside nanopores in the form of layers covering uniformly the solid surface, of plugs filling locally the pore space, or of capsules floating in the middle of the pores. In the present contribution, we report in situ synchrotron small-angle scattering (SAXS) experiments on hexane/nitrobenzene solutions confined in mesoporous carbon xerogels [2]. The SAXS shows that these systems exhibit reversible temperature-induced transitions between the layer and the plug configurations. The scattering data is analyzed using a so-called plurigaussian model, which enables us to reconstruct the configurations of the confined liquids, and quantitatively analyze the wetting transitions at the nanometer-scale in terms of changing interface areas, contact angles, and triple-line lengths.

Introduction. The health reform law crystallizes the tensions between the different health system players. Besides the specific issue of third-party payment, which will be addressed in an upcoming article, some professional organizations wish to strengthen fee for servicies while others call for more mixed forms of remuneration. Many economic analyses were conducted to study the benefits and limits of each mode of physician compensation. This article offers a synthesis of the literature about these modes: fee for service, capitation, payment performance and wage labor. Method. Collaborative literature analysis between doctors and health economist. The databases searched were MEDLINE, the Cochrane Library and CAIRN. Results. Each mode has specific benefits and limits for the financer, the physicians and the patients. Fee for services increases physician productivity but may increases health spending. Capitation and salary decrease care supply but might help to control health spending and to develop preventive activities. The effectiveness of pay for performance is now being questioned. The current trend is to promote mixed forms of remuneration, hoping to combine the advantages and limit the share of defects of each modality. The complexity of such systems makes it difficult to compare from one country to another. Discussion. The choice of a mode by the financer must take into account both the possible combinations of different payment methods and the developments or societal aspirations to meet population health needs.

Dans le cadre d’un recensement des terrils situés en Région wallonne et pouvant présenter des risques de stabilité sur le court et le long terme, l’ISSeP a chargé le Laboratoire de Géotechnologies de l’Université de Liège, représenté par Ir. F. COLLIN et S. DELVOIE, de réaliser une étude géotechnique préliminaire. Les objectifs de ce travail sont tout d’abord de recenser les informations disponibles sur le sous-sol aux environs immédiats des terrils. Les données recueillies sont ensuite exploitées par des outils informatiques SIG et seront par la suite utilisées dans l’évaluation du risque d’instabilité, réalisée par l’ISSeP. Ce travail documentaire est également complété par une inspection sur le terrain de chaque terril étudié. Les terrils faisant partie de l’étude géotechnique sont repris dans la liste ci-dessous : - L60 – Petite Bacnure - L53 – Gosson 2 - L39 – Bonne Espérance et Bonne Fortune - L46 – Xhorre - L41 – Espérance 3 - L55 – Horloz [less ▲]

Security control is becoming a major global issue in strategic locations, such as airports, official buildings, and transit stations. The agencies responsible for public security need powerful and sensitive tools to detect warfare agents and explosives. Volatile signature detection is one of the fastest and easiest ways to achieve this task. However, explosive chemicals have low volatility making their detection challenging. In this research, we developed and evaluated fast chromatographic methods to improve the characterization of volatile signatures from explosives samples. The headspace of explosives was sampled with solid phase micro-extraction fiber (SPME). Following this step, classical gas chromatography (GC) and comprehensive two-dimensional GC (GC×GC) were used for analysis. A fast GC approach allows the elution temperature of each analyte to be decreased, resulting in decreased thermal degradation of sensitive compounds (e.g., nitro explosives). Using fast GC×GC, the limit of detection is further decreased based on the cryo-focusing effect of the modulator. Sampling of explosives and chromatographic separation were optimized, and the methods then applied to commercial explosives samples. Implementation of fast GC methods will be valuable in the future for defense and security forensics applications. [less ▲]

We investigate the relationship between corporate board of directors’ attributes and conditional accounting conservatism in the French context. Using a pooled regression model over the period 2009-2012, our empirical results can be summarized as follows. First, greater board activity encourages more conservative reporting in financial statements. Second, larger board size diminishes conditional accounting conservatism. Lastly, there is a positive association between gender diversity and accounting conservatism. As a robustness test, we use alternative measures of accounting conservatism, namely time series and accrual-based measures in addition to asymmetric timeliness of earnings. Our findings suggest that boards of directors’ attributes are an important factor in determining the financial reporting quality of French firms. [less ▲]

This paper presents a research on a specific type of unstiffened extended end-plate joint used to connect I-shaped beams to concrete-filled rectangular hollow section columns. The main idea is to use long bolts throughout the column to connect the beam end-plates, so avoiding intermediate connecting elements (e.g. a reverse U channel) or special bolts (e.g. blind bolts). However, the use of long bolts for beam-to-column connections is still rare in the construction and no design procedure exists in the Eurocodes; this justifies the pre-sent research. Firstly, a test program within a RFCS European project titled HSS-SERF “High Strength Steel in Seismic Resistant Building Frames”, 2009-2013 was performed. In this project, specimens subjected to sig-nificant bending moments (and shear) or to shear only was defined. Then, analytical developments based on the component approach and aimed at predicting the joint response have been carried out; their validity is demonstrated through comparisons with the tests. Finally, design guidelines have been provided. [less ▲]

Large surveys in Western countries give pictures of adolescent well-being related to delinquency and group affiliation. The belonging to a particular country, city or neighbourhood with their social structure influences the probability to have delinquent activities in group increasing or decreasing the risk of marginalisation, the sensibility to deviant values and the well-being related to peers’ acceptance. A general process would exist by which, firstly adolescents oppose themselves to the parents’ authority and seek for acceptance among their peers. This leads to a spiral when the youth tries to resolve his cognitive dissonance between the immoral acts he is invited to commit with his friends and his personal value system learned in his family, school and other institutions. In adolescence, the influence of peers can be positive or negative; it can be “protective peer-contagion” with positive response to normative talk or “deviant peer-contagion” with positive response to deviant talk or behaviour. At the micro level, well-adjusted peers are able to resist the influence of deviant peers. The participation to non-homogenous mixed groups seems to facilitate more normative talks. This leads to the hypothesis that the progressive extension to differentiated groups when adolescence is going through will strengthen their ties with conventional norms and contribute to their well-being.
