Cette contribution porte sur les enjeux que soulève la réforme des soins de santé mentale en Belgique, au carrefour de l’évolution socio-historique du secteur, et d’un modèle des soins inscrit au sein de tendances internationales. Précisément, l’objectif est de mettre en tension l’indétermination du modèle, au sens où il renvoie à un ensemble d’expériences étrangères plus qu’un un corpus de savoirs; et la configuration d’une offre de soins encore déterminée par ses frontières institutionnelles.

The effect of heat treatments (drying and hydrothermal treatment) on the extractability of salt-soluble protein (SSP) was assessed using Promatest methodology for corn kernels heated between 60 C and 120 C. During drying, the evolution of the grain moisture content is fitted using the analytical solution of Fick equation developed by Crank (1979) for spherical material. The decrease of extractible salt-soluble protein during heating is forecasted using a first and a second order ordinary differential equation. It was found that temperature; moisture content and time of processing greatly influence the kinetic denaturation of SSP of corn kernels. The evolution of extractible SSP content of corn kernels during drying at high temperature is more correctly described with second order kinetic than with the first order kinetic reaction. The Hunterlab color parameters of corn also vary during drying. Lightness and color intensity decrease while yellowness, redness, chroma and hue angle increase through drying time. Most of these Hunterlab color parameters are highly correlated with the salt-soluble proteins content and therefore could be used as indicators of excessive heat treatment and denaturation of salt-soluble proteins in corn kernels [less ▲]

Ultraviolet (UV) spectra of the delta (190-240 nm) and gamma (225-270 nm) bands of the nitric oxide (NO) molecule have been measured in the atmosphere of the Venus night side with the Spectroscopy for Investigation of Characteristics of the Atmosphere of Venus (SPICAV) instrument on board Venus Express (VEX). Excited NO molecules on the night side of the planet find their source in the radiative recombinaison of O(3P) and N(4S) atoms produced on the dayside by Extreme Ultraviolet (EUV) solar photons that cause photodissociation of CO2 and N2 molecules. We analyse with an improved statistics the behaviour of the vertical emission profile of the NO nightglow. We also present a method used to retrieve and analyse the volume emission rate. We describe the dependence of the vertical distribution with latitude and local time and its variability. New features in the vertical distribution of the NO emission such as double peaks are also exhibited. Furthermore, we use a one-dimensional chemical-diffusive model to compare the major features of the calculated O2 1.27 microm and NO UV emissions profiles with those observed with SPICAV. [less ▲]

Introduction: Tendinopathies, especially jumper’s knee, often remain rebel to conservative treatments. Several experimental studies have shown the healing properties of platelet and their growth factors. Researches have specifically demonstrated the platelets action as mediator and/or enhancer of tissue healing. The aim of our study was to investigate the effect of 1 injection of PRP in patients suffering from chronic jumper’s knee. Our protocol was approved by Ethic Committee of University and University Hospital of Liège. Methods: Patients performed imaging (US and MRI) and functional assessments, and a clinical examination using an algometer, before treatment and 6 weeks after PRP treatment. They were also invited to answer to questionnaire relative to pain and functional status. PRP was obtained from autologous blood using an apheresis system (COM.TEC, Fresenius). The injection of 6mL of PRP was realised without local anaesthesia into the proximal insertion of the patellar tendon. A 48h rest-time was recommended after infiltration. Afterwards, a submaximal eccentric reeducation was initiated 1 week after infiltration 3 times a week during 5 weeks. In case of pain, anti-inflammatory drugs were prohibited and patient were encouraged to take class I or II painbrakers. Results: At this time, 10 patients with jumper’s knee were included in our study. Pre-injection tests revealed pain of the upper part of the patellar tendon just below the patella, associated with loss of function. Imaging exams confirmed diagnosis. Six weeks post-injection, the clinical status was improved in all patients, with a significant decrease of algo-functional scores. The pain reported during functional assessments was decreased (in particular for the eccentric actions), yet no significant improvement of physical performances was observed. We found no significant differences between imaging exams before and 6 weeks after PRP injection. Conclusion: One in situ injection of PRP clinically improved patients with jumper’s knee 6 weeks after treatment. All the 10 patients reported a decrease of pain during day-life and through physical activities. However nor functional performances neither imaging were improved. [less ▲]

Lymphoid tyrosine phosphatase (LYP) and C-terminal Src kinase (CSK) are negative regulators of signaling mediated through the T cell antigen receptor (TCR) and are thought to act in a cooperative manner when forming a complex. Here, we show that dissociation of the LYP/CSK complex is necessary for recruitment of LYP to lipid rafts, where it down-modulates TCR-mediated signaling. Our findings may also explain the reduced TCR signaling associated with a single nucleotide polymorphism, which confers increased risk for autoimmunity and results in the expression of a LYP allele that can no longer bind CSK. Development of a potent and selective chemical probe of LYP allowed us to confirm that the observed down-modulation of TCR-induced signaling was due to the LYP catalytic activity. Our compound also represents a starting point for the development of a LYP-based treatment of autoimmunity. [less ▲]

On the ground of a three years-long multi-sited, ethnographic research conducted in Southern Nigeria, Italy and the United Kingdom, my PhD dissertation analyzes the processes of transnationalization that have affected the southern Nigerian video film industry (Nollywood) during the first decade of the 2000s, and interpret their significance in relation to the industry’s history and recent developments. Transnationalization processes have affected the industry at different levels, which include its economic and social organization, its international representation, and the narrative and aesthetic features of the films it produces. The dissertation analyzes these different levels through three separated, but interrelated, sections: 1) The Nigerian video industry has experienced a transnational success since its early stages. Thanks to the informality of Nollywood’s network of distribution, pirated copies of Nigerian videos have circulated throughout the world since the mid 90s. Informal and pirated networks of circulation made videos travel long distances and create for the industry a wide transnational audience. However, as this section argues, informal production and distribution strategies and their vulnerability to piracy progressively eroded the industry’s economy. This section then argues that, once the internal Nigerian video market has started to implode because of the excess of informality and the lack of a proper distribution framework, an important section of the industry has explicitly decided to target the transnational audience generated by the global informal circulation of Nigerian video films. New modes of production and circulation emerged, which mainly target local elites and diasporic audiences. A new wave of high budget productions saw the light. The videos’ patterns of mobility transformed and, this impacted on video films’ economic accessibility for local popular audiences. 2) The second section analyzes the way videos’ discursive circulation (that is, the way in which videos, and the video phenomenon in general, have been portrayed, discussed and analyzed both in Nigeria and elsewhere) impacted on the video industry’s transformation. As with the material and economic circulation analyzed in the first section, videos’ discursive circulation interacted with the video phenomenon in at least two ways. On the one hand it made videos travel. It made them cross boundaries and reach audiences they did not even envisaged to reach. On the other hand, it opened for the video industry a field of dynamic confrontation. Nollywood has been compared to other global film industries (such as Bollywood and Hollywood), and it has been criticized for its low production quality standards. The video phenomenon has been celebrated for some of its achievement, and mocked for some of its weaknesses. This complex interaction with the global cinema arena has produced numerous effects on the video industry. Videos entrepreneurs reacted to criticism and engaged into active processes of transformation aimed at making the video industry reach international production quality standards, and escape the marginal position within which much of the mentioned discursive constructions positioned it. 3) The third section looks at videos’ aesthetics and narrative structures. The transnational mobility of the videos impacted on them in multiple ways. On the one hand, as a result of the encounter of both transnational and local aesthetic and narrative aspects, videos developed a particular aesthetic and narrative openness which made them able to address dispersed audiences and reconstitute them into a pan-African public. Through their specific film language, contents, and forms of address videos activated a debate on what it means to be African today, and shaped it around the social, cultural and historic specificities of the post-colonial, post-Structural-Adjustment era in Nigeria and, more generally, in sub-Saharan Africa. On the other hand, mobility intervened in the reformulation of videos’ narrative and aesthetic patterns. The video phenomenon has been adopted and reinterpreted by Nigerian diaporic groups in Europe and elsewhere. The specific social and economic conditions associated with the experience of living in the diaspora interacted with the videos’ production strategies and defined particular narrative and aesthetic solutions. When the Nigerian video industry entered the production crisis diasporic production companies found themselves in the position of an avant-garde in what concerns the industry’s transnational expansion: they had already experimented with economic and aesthetic solutions that could open Nigerian productions to global audiences. As a result, they became the bridge able to connect the Nigerian video film industry to transnational, non-African audiences. [less ▲]

We make an epistemological analysis of the theorem that inspired us the set up of a situation composed of four mathematics statements and for which we need rectilinear movements with or without variable speeds, speeding and moving laws, areas, volumes and flows. The suggested strategies for these statements and the reactions will be analysed later. [less ▲]

Ce chapitre vise à présenter les règles juridiques qui déterminent le rythme électoral. Il commence par une courte discussion sur la question de savoir quel laps de temps peut être considéré comme une durée raisonnable pour une législature. Il se poursuit par le passage en revue les normes qui établissent, pour chacune des assemblées élues du pays, la durée qui sépare en principe deux élections , et par l'examen des cas où la législature est écourtée par l’organisation d’élections anticipées. Enfin, le chapitre s'achève par une brève réflexion sur l’opportunité d’une synchronisation des différentes échéances électorales. [less ▲]
