ABSTRACT The identification of additional chemotherapy agents for anthracycline- and taxane-pretreated advanced breast cancer (ABC) is an urgent medical need. Single agent chemotherapy is most times administered because combined therapy is only associated with modest, if any, improvement in median progression-free survival. Randomized trials failed to show overall survival benefit compared with single agent chemotherapy. We hope to modify the natural history of ABC by the consecutive use of treatments with documented activity in heavily pretreated patients. Quality of life remains an important end point as cure is in general not possible. We first review the activity of the approved and the most frequently used agents in heavily pretreated ABC. Thereafter, the potential role and safety profile of etirinotecan pegol is discussed given the results recently released of a Phase III trial comparing this agent to Treatment of Physician's Choice.

Viral diseases of the respiratory tract, which include influenza pandemic, children acute bronchiolitis, and viral pneumonia of the elderly, represent major health problems. Plasmacytoid dendritic cells play an important role in anti-viral immunity, and these cells were recently shown to express ChemR23, the receptor for the chemoattractant protein chemerin, which is expressed by epithelial cells in the lung. Our aim was to determine the role played by the chemerin/ChemR23 system in the physiopathology of viral pneumonia, using the pneumonia virus of mice (PVM) as a model. Wild-type and ChemR23 knock-out mice were infected by PVM and followed for functional and inflammatory parameters. ChemR23(-/-) mice displayed higher mortality/morbidity, alteration of lung function, delayed viral clearance and increased neutrophilic infiltration. We demonstrated in these mice a lower recruitment of plasmacytoid dendritic cells and a reduction in type I interferon production. The role of plasmacytoid dendritic cells was further addressed by performing depletion and adoptive transfer experiments as well as by the generation of chimeric mice, demonstrating two opposite effects of the chemerin/ChemR23 system. First, the ChemR23-dependent recruitment of plasmacytoid dendritic cells contributes to adaptive immune responses and viral clearance, but also enhances the inflammatory response. Second, increased morbidity/mortality in ChemR23(-/-) mice is not due to defective plasmacytoid dendritic cells recruitment, but rather to the loss of an anti-inflammatory pathway involving ChemR23 expressed by non-leukocytic cells. The chemerin/ChemR23 system plays important roles in the physiopathology of viral pneumonia, and might therefore be considered as a therapeutic target for anti-viral and anti-inflammatory therapies.

Le chêne n’est pas une essence facile à conduire vers la production de bois de qualité. Pour beaucoup d’entre eux, leur forme a été conditionnée il y a plus d’un siècle au sein de peuplements bien différents de ce qu’ils sont devenus car originellement adaptés aux conditions socio-économiques qui prévalaient aux XIXe et au début du XXe siècle. Mais dans bien des cas, la sylviculture que l’on mène maintenant est encore sous la contrainte de ce passé. Cet article envisage les contextes « historico-sylvicoles » des chênaies de Wallonie à la lumière de leur état actuel. [less ▲]

Dans la forêt ardennaise, les chênes sont en nette diminution. Plusieurs facteurs sont responsables de cette diminution, voici quelques exemples : régénération plus difficile que le hêtre, abroutissement par le gibier, mauvaise réputation de la qualité du chêne ardennais dû aux anciens traitements, conditions de marché du bois défavorable aux essences à grandes révolution. Pourtant, ces dernières années, on prend conscience de leur importance. Les apports du chêne dans la hêtraie ardennaise sont nombreux, notamment dans le contexte du changement climatique : le chêne favorise le développement d’un cortège d’organismes diversifiés, favorise la décomposition de la litière et la fertilité des sols, permet l’exploitation des stations impropres au hêtre, favorise la stabilité des peuplements et permet la production de bois de qualité. Favoriser la régénération du chêne requiert une sylviculture interventionniste, les éléments principaux sont l’apport de lumière et la protection contre le gibier. Même s’il est possible de donner des pistes pour favoriser le chêne, de nombreuses questions se posent encore. Dans le contexte de l’Accord-cadre de recherche et vulgarisation forestières, l’ULg (GxABT) et l’UCL ont mis en place des dispositifs qui devraient bientôt permettre de mettre au point des scénarios sylvicoles.

Ground based radial velocity (RV) searches continue to discover exoplanets below Neptune mass down to Earth mass. Furthermore, ground based transit searches now reach milli-mag photometric precision and can discover Neptune size planets around bright stars. These searches will find exoplanets around bright stars anywhere on the sky, their discoveries representing prime science targets for further study due to the proximity and brightness of their host stars. A mission for transit follow-up measurements of these prime targets is currently lacking. The first ESA S-class mission CHEOPS (CHaracterizing ExoPlanet Satellite) will fill this gap. It will perform ultra-high precision photometric monitoring of selected bright target stars almost anywhere on the sky with sufficient precision to detect Earth sized transits. It will be able to detect transits of RV-planets by photometric monitoring if the geometric configuration results in a transit. For Hot Neptunes discovered from the ground, CHEOPS will be able to improve the transit light curve so that the radius can be determined precisely. Because of the host stars' brightness, high precision RV measurements will be possible for all targets. All planets observed in transit by CHEOPS will be validated and their masses will be known. This will provide valuable data for constraining the mass-radius relation of exoplanets, especially in the Neptune-mass regime. During the planned 3.5 year mission, about 500 targets will be observed. There will be 20% of open time available for the community to develop new science programmes. [less ▲]

Our study about the institutionalization process of social regulation practices emerging at the inter-organizational level led us to develop an action-research methodology of entrepreneurial nature. This methodological choice gave rise to original and rich data, but simultaneously challenged our ability to analyze these data as well as our entrepreneurial role in a reflexive way. The central question of this paper is then twofold: on the one hand, can the researcher be an “entrepreneur”, and go beyond the simple production of knowledge? On the other hand, can the researcher with an entrepreneurial position produce scientific knowledge? We will answer these two questions thanks to two case studies, which will allow us to highlight various facets of acting as a “researcher-entrepreneur”. [less ▲]

Availability of an article on the Internet without any barrier increases by a 20-fold factor its downloading songs as compared to those in restricted access requiring a reprint request. An article is being cited twice as much if immediately accessible. It is a fact. Hence it is crucial, if one wants to be read (why else would one one publish ?) to deposit one's manuscripts immediately after acceptance (i.e. before publication) and to make them freely accessible as soon as permitted. | L'accessibilité d'un article sur l'Internet sans aucune entrave technique augmente d'environ 20 fois ses téléchargements par rapport à l'accès restreint nécessitant une demande de tiré-à-part. Un article est cité environ 2 fois plus s'il est directement accessible. C'est une réalité. Il est donc crucial, si l'on veut être lu (sinon, pourquoi publie-t'on?) de déposer ses manuscrits immédiatement après acceptation (donc avant la publication) et de les rendre librement accessibles dès le moment où on y est autorisé.

To determine the relative contribution of rib cage and abdominal muscles to expiratory muscle activity during quiet breathing, we used lumbar epidural anesthesia in six pentobarbital sodium-anesthetized dogs lying supine to paralyze the abdominal muscles while leaving rib cage muscle motor function substantially intact. A high-speed X-ray scanner (Dynamic Spatial Reconstructor) provided three-dimensional images of the thorax. The contribution of expiratory muscle activity to tidal breathing was assessed by a comparison of chest wall configuration during relaxed apnea with that at end expiration. We found that expiratory muscle activity was responsible for approximately half of the changes in thoracic volume during inspiration. Paralysis of the abdominal muscles had little effect on the pattern of breathing, including the contribution of expiratory muscle activity to tidal breathing, in most dogs. We conclude that, although there is consistent phasic expiratory electrical activity in both the rib cage and the abdominal muscles of pentobarbital-anesthetized dogs lying supine, the muscles of the rib cage are mechanically the most important expiratory muscles during quiet breathing.

The Ardennais draught horse (DH) is more and more used for harnessing competitions. The aim of this study was to improve our knowledge of its cardiorespiratory peculiarities, both at rest and during exercise. At rest, arterial blood gas analysis, venous blood analysis, a test of mechanics of breathing and an endoscopy of the upper airways were performed. Experiments during exercise were performed on a treadmill. The intensity of the standardised test was sufficient to overshoot the OBLA threshold. The test was of increasing intensity and lasted 22 min. The cardiorespiratory parameters were measured during the last 5 min. Expired volume minute (VE), VT and f were measured. Respiratory O2 and CO2 fraction were measured with a mass spectrometer. Oxygen uptake (VOA, CO2 output (VCO2) and VE/VO2 were calculated. Heart rate (HR) was continuously measured.The results were compared to data recorded in standarbred horses (SH) during a treadmill exercise test leading to a similar lactaci¬demia (LA) and peak HR.The DH have a significantly lower V02 than the SH while running at an exercise intensity inducing the same HR and LA modifications. The lower aerobic capacity of DH was at least partly correlated with their higher cost of breathing and lower blood gas transport capacity.Moreover, other measurements have been performed infield conditions, during 4 draft competitions, i.e. speed, maniability, power and endurance. Venous blood analyses before and after the competition, heart rate and body temperature measurements were performed. The results of this second set of measurements confirm the results obtained in the laboratory and allow assessing that these kinds of competition do not induce dramatic physiological modifications and therefore respect the welfare and limits of these horses.

Le traitement réservé par la logique frégéo-russellienne aux énoncés de fiction est notoirement insatisfaisant; il impose notamment de considérer que "Tous les chevaux ailés ont des ailes" est vrai, mais que "Pégase a des ailes" est faux. Parmi les modèles d'analyse alternatifs qui ont été proposés au XXème siècle, le cadre des logiques meinongiennes semble, dans un premier temps, plus prometteur. Il pêche cependant par un parti-pris descriptiviste qui le rend, pour sa part, moins apte à traiter des énoncés portant sur les objets réels. Nous tâcherons de présenter les options théoriques générales sous-jacentes aux deux types de logiques (dont nous montrerons aussi plusieurs variations) ainsi que les caractérisations des notions d'objet et de vérité qui en résultent [less ▲]
