Glick and Fiske's (1996) Ambivalent Sexism Inventory is a measure of hostile sexism (sexist antipathy) and benevolent sexism (a subjectively positive attitude toward women). This paper proposes a French version of this scale, the Echelle de Sexisme Ambivalent (ESA). Three studies on more than 1000 participants established the validity of this new scale. The first one is the application of Rasch's extended model that confirmed the psychometrical qualities of the ESA, for both male and female participants. The second study established the structural and predictive validity in a covariance analysis. This study again showed that both male and female participants displayed the same structural pattern. Next, both discriminant and convergent validity were assessed, by comparison to the Neosexism Scale (Tougas, Brown, Beaton and Joly, 1995) and the Social Dominance Scale (Sidanius and Pratto, 1999). Finally, practical and theoretical implications are discussed. [less ▲]

Context: High angular resolution imaging of nearby pre-main sequence stars with ages between 1 and 30 Myr can give valuable information on planet formation mechanisms. This range of ages is thought to correspond to the dissipation of the optically thick dust disks surrounding young stars and to the end of the planet formation. Aims: This paper presents new observations of three weak-line T Tauri Stars (WTTS) of intermediate ages ranging from 7 to 16 Myr. It aims at increasing the knowledge and sample of circumstellar disks around "old" WTTS. Methods: We observed three stars with the VLT's NAOS-CONICA adaptive optics system in coronagraphic mode. The four-quadrant phase mask coronagraph was used to improve the dynamic range (by a factor of 100) while preserving the high angular resolution (inner working angle of 0farcs 15). Results: One object of our sample (PDS 70), a K5 star, exhibits a brown dwarf companion and a disk in scattered light with a surface brightness power law of r[SUP]-2.8[/SUP], extending from a distance of 14 to 140 AU (assuming a stellar distance of 140 pc) and an integrated luminosity of 16.7 mJy in the K_s-band. The mass of the companion can be estimated to be within a range between 27 and 50 Jupiter masses with an effective temperature of 2750 ± 100 K. This object also shows a resolved outflow stretching up to 550 AU. Conclusions: This newly detected circumstellar disk shows strong similarities with the disk around TW Hya, and adds to the observed population of "old" TTS surrounded by circumstellar material. Moreover, three clues of planetary formation are brought to light by this study. [less ▲]

Recent publications about carotid-stenting are submitted to a critical analysis. The fact that an interventional approach in asymptomatic carotid lesions generates only marginal benefit being universally admitted, it is disturbing to see that modern series devoted to carotid artery stenting include a lot of asymptomatic patients and many symptomatic patients with a degree of stenosis well below the optimal range defined in NASCET (70 to 99%). Moreover, the degree of stenosis is often calculated from an inappropriate method that overestimates the degree of stenosis. Two objections have been made about an "hyper-selection" of the patients enrolled in the NASCET study and the production of ideal not realistic results, not attainable in community hospitals; both objections have been overruled. The rate of acute perioperative myocardial infarction is mentioned, both in NASCET and ECST, it is around 0.9% vs 7.5% in SAPPHIRE study. Moreover, carotid artery stenting with an embolic protection device has resulted in the production of infra-clinical cerebral micro-infarcts in 40% of the patients. Significantly, the independent study EVA-3S, devoted to symptomatic patients had to be stopped because of the high cerebral morbidity in the dilatation-stenting group. Carotid artery stenting of asymptomatic lesions is futile (and potentially harmful because of microinfarcts) while carotid artery stenting of symptomatic lesions generate emboli. [less ▲]

Primary aorto-oesophageal fistula, secondary to an aneurysm of the thoracic aorta, are almost fatal. In the literature, only twenty six successfully operated cases have been reported. We report the case of a 78-year-old man with a thoracic aortic aneurysm eroded into the mid oesophagus. Prompt diagnosis of an aorto-oesophageal fistula resulted from clinical history, CT-imaging and oesophagoscopy. The patient was successfully operated by exclusion of the thoracic aneurysm (insertion of a straight cryopreserved arterial allograft), oesophagectomy and cervical oesophagostomy and jejunostomy. The continuity of the digestive tube was later restored after preliminary aortic valve remplacement (stenosis of 0.8 cm2). This case report is the second in which a cryopreserved allograft was successfully implanted in the management of a primary aorto-oesophageal fistula. [less ▲]

We present a complete analysis of the laser control of a model molecular system using both optimal control theory and adiabatic techniques. This molecule has a particular potential energy surface with a bifurcating region connecting three potential wells which allows a variety of processes such as isomerization, tunneling, or implementation of quantum gates on one or two qubits. The parameters of the model have been chosen so as to reproduce the main features of H3CO which is a molecule benchmark for such dynamics. We show the feasibility of different processes and we investigate their robustness against variations of laser field. We discuss the conditions under which each method of control gives the best results. We also point out the relation between optimal control theory and local control. [less ▲]

La maîtrise du risque lié à Listeria monocytogenes commence par la mise en place d’un système d’autocontrôle adapté à la transformation fermière. La recherche de mesures plus spécifiques à Listeria monocytogenes ne s’applique que si l’aliment et/ou les conditions de travail présentent un risque réel de contamination et/ou de multiplication du germe étudié. Cette étude doit être adaptée à chaque exploitation. Pour les produits au lait cru, la prévention commence au niveau de l’élevage (qualité de l’ensilage) et de la production de lait (hygiène à la traite). Pour la transformation, la maîtrise du froid et de l’acidification permet de limiter, voir de stopper le développement des Listeria monocytogenes éventuellement présentes. [less ▲]

Malgré toute la modernité qui caractérise nos sociétés, nombre de phénomènes paraissent encore et toujours en attente de politiques et d’actions adéquates et concertées. La santé n’échappe évidemment pas à cette situation, et ce malgré, les préoccupations croissantes en la matière. La difficulté est d’autant plus insurmontable que la santé représente un domaine d’investigation gigantesque où se croisent, si l’on adopte la définition de l’OMS1, une myriade d’acteurs de terrain en prise avec une quantité potentiellement illimitée de dimensions influençant la santé. Si les conditions de vie semblent s’améliorer dans un certain nombre de pays, on peut regretter que ce constat ne puisse être étendu à l’ensemble de la planète. L’objectif poursuivi par les pays fondateurs de l’OMS en 1946 d’atteindre le plus haut niveau de santé pour l’ensemble des individus, reste donc encore et toujours devant nous.Si tout le monde sait que la santé ne se décrète pas, personne ne niera que la santé est le fruit de la rencontre de « circonstances » qui sont par contre produites par nos sociétés. Les pouvoirs publics ont, dans ce contexte, une part de responsabilité indéniable. Plus précisément, les mandataires publics ont pour mission, à tout le moins dans les systèmes politiques démocratiques, d’assurer à l’ensemble de la population, des conditions de vie acceptables. Si l’on concentre son attention sur les pays les plus favorisés, on se rend compte de l’existence d’un certain nombre de difficultés pour une gestion cohérente et efficace de la santé. [less ▲]

Objective: To confirm in vivo the hypothesis that hemofiltration with a large pore membrane can achieve significant cytokine clearance. Method: We used a well-known animal model of endotoxinic shock (0.5 mg/kg of lipopolysaccharide from Escherichia Coli over a period of 30 mins). Six pigs were hemofiltrated for 3 hours with a large pore membrane (78 angstrom pore, 80 kDa cut off) (Sureflux FH 70, Nipro, Osaka, Japan). The ultrafiltration rate was 45 ml/kg/min. Samples were taken from arterial, venous line and in the ultrafiltrate at T120 and T240. We measured concentrations of interleukin 6, interleukin 10 and albumin. Results: At T120 and T240, the IL-6 clearances were 22 +/- 7 and 15 +/- 3 ml/min, respectively. The IL-6 sieving coefficients were 0.97 and 0.7 at T120 and T240, respectively. At T120 and T240, the IL-10 clearances were 14 +/- 4 and 10 +/- 7 ml/min, respectively. The sieving coefficients were 0.63 and 0.45 at T120 and T240, respectively. The concentrations of IL-6 and IL-10 were the same at T0 and T240. At T60 and T240, the plasmatic albumin concentrations were 24 +/- 4 g/L and 23 +/- 4 g/L, respectively ( p = 0.13). Conclusions: In this animal model of endotoxinic shock, we confirm the high cytokine clearance observed when hemofiltration is applied to a large pore membrane. The loss of albumin seems negligible. The impact of such clearances on hemodynamic stability and survival remains to be proved. [less ▲]

Exacerbations of chronic obstructive pulmonary disease (COPD) play a very important role. Unfortunately they were neglected a long time in the therapeutic tests. However exacerbations influence the decline of the respiratory function over time, cause important deterioration of the quality of life of the patients, increase morbidity and mortality of COPD, and finally represent a burden for health care. Reducing the number of exacerbations could potentially slow down the progression of the disease. Thus the prevention of exacerbations should be the "corner stone" of the maintenance treatment of the COPD. In this review we propose to recall the importance of exacerbations in COPD and to present the treatment which have been shown to reduce exacerbation rate in COPD. [less ▲]
