Many complex IT projects are still primarily focusing on today's technological challenges. The adaptation of the core technologies to potential applications often occurs in a second stage where the end-users are involved. We describe a different approach, involving the users at the very beginning of the development. The domain we address is the creative design, mainly architecture. Rooted in a multidisciplinary approach as well as a deep understanding of architecture and design, our method aims at proposing adapted mixed reality solution to support two crucial activities : sketch-based preliminary design and distant synchronous collaboration in design. This chapter provides a summary of our work on a mixed-reality device based on a drawing table (the Virtual Desktop) designed specifically to address real-life/trade-focused issues. We explain our methodology, describe the two supported activities and the related users’s needs, we detail the technological solution we have developed and we present the main results of the multiple evaluation sessions. We then conclude on the usefulness of the profession-centered methodology and on the pertinence of the mixed reality to support creative design activities. [less ▲]

Angiogenesis is a hallmark of tumours. The newly formed tumour vessels are structurally and functionally abnormal leading to tumour perfusion heterogeneities and subsequently to the development of hypoxic areas. Generally, tumour hypoxia refers to an increasing distance between vasculature and tumour cells (i.e. chronic hypoxia). Chronic hypoxia promotes tumour resistance to treatments and metastasis. The temporal aspect of hypoxia is completely neglected in chronic hypoxia. Intermittent hypoxia (HI) takes the transient and temporal aspect of hypoxia into account. HI is defined as pO2 fluctuations in tumour vessels secondary to transient arrest of tumour blood flow. IH extends the concept of tumour hypoxia to tumour vessels and vascular cells. Transient arrest of tumour blood flow promotes tumour resistance to radio- and chemotherapy treatments and favours metastasis. Moreover, IH protects tumour vessels and endothelial cells against pro-apoptotic stresses and promotes angiogenesis. A comprehensive dissection of the mechanisms leading to IH allows the development and establishment of new therapeutic approaches. [less ▲]

Background : Reccurences of herpes labialis (RHL) may be triggered by systemic factors, including stress, menses, and fever. Local stimuli, such as lip injury or sunlight exposure are also associated to RHL. Dental extraction has also been reported as triggering event. Case report : Seven otherwise healthy patients are presented with severe and extensive RHL occuring about 2-3 days after dental extraction under local anaesthesia. Immunohistochemistry on smears and immunofluorescence on cell culture identified herpes simplex virus type I (HSV-I). Five patients reported more severe prodromal signs than usual. Although all the patients suffered from RHL, non had previously experienced RHL after dental care. Two patients required hospitalisation for intravenous acyclovir therapy, whereas the others were successfully treated with oral valaciclovir or acyclovir. Conclusion : Severe and extensive RHL can occur soon after dental extraction under local anaesthesia. Patients a with previous history of RHL seem to be at higher risk. It is not clear whether RHL is linked to the procedure itself, to the anaesthetic procedure or both. As the incidence is unknown, more studies are required to recommend prophylactif antiviral treatment in RHL patients who are undergoing extractions. Dentists should be aware of this potentially servere post-extraction complication. [less ▲]

Les troubles spécifiques de développement du langage (TSDL), dont les formes sévères sont appelées dysphasies, sont caractérisés par un développement lent et anormal du langage. Par définition, les enfants ayant ce type de trouble ne doivent pas présenter d’autres déficits attestés qu’ils soient cognitifs ou neurologiques. Il existe de nombreux profils développementaux de TSDL qui peuvent évoluer au cours de leur développement, ce qui les rend difficiles à caractériser. L’origine des TSDL est actuellement inconnue et les nombres études sur le sujet sont parfois contradictoires. Nous avançons un ensemble de propositions cliniques et théoriques pour remédier à ces difficultés : • Les TSDL sont un nom générique pour trois types de troubles clairement différenciés : la dyspraxie développementale verbale, la dysphasie linguistique , et les troubles pragmatiques du langage. • Il n'existe pas une cause unique pour les TSDL. Au contraire, chaque TSDL est la conséquence de la présence chez l’enfant d’une conjonction de déficits de base. • Chaque TSDL est le résultat d'un déroulement anormal du développement du langage. Ces anomalies apparaissent lorsque plus d'une partie du système est déficiente et que les mécanismes naturels de compensation du système deviennent inefficaces. • Les phénomènes de compensation sont eux-mêmes des phénomènes langagiers et de ce fait ils interfèrent avec l'évaluation langagière proprement dite. Pour comprendre le fonctionnement cognitif et langagier dans sa complexité, il est nécessaire pour le diagnostic et la prise en charge d’utiliser une évaluation de capacités sous-jacentes non-langagières. • Les bases neurologiques plausibles du langage et de son développement doivent être prises en compte pour offrir de nouvelles hypothèses et thèmes de recherche pour le travail futur sur les TSDL.

The prescriptive component of stereotypes is defined as a set of beliefs about the characteristics group members should possess. It has mainly been studied regarding gender stereotypes. We believe that the main function of this prescriptive component is to allow dominant group members to maintain subordinate group members in an advantageous position for themselves. To illustrate our proposal, we present several theoretical and empirical papers, showing that the relative status of social groups is a determinant of which characteristics are prescribed to the members of these groups; that subordinates who fail to conform to the prescription are sanctioned; and that dominants prescribe to subordinates characteristics they see as beneficial to their own group.

Estuarine turbidity maxima (ETMs) are sites of intense mineralisation of land-derived particulate organic matter (OM), which occurs under oxic/suboxic oscillating conditions owing to repetitive sedimentation and resuspension cycles at tidal and neap-spring time scales. To investigate the biogeochemical processes involved in OM mineralisation in ETMs, an experimental set up was developed to simulate in vitro oxic/anoxic oscillations in turbid waters and to follow the short timescale changes in oxygen, carbon, nitrogen, and manganese concentration and speciation. We present here the results of a 27-day experiment (three oxic periods and two anoxic periods) with an estuarine fluid mud from the Gironde estuary. Time courses of chemical species throughout the experiment evidenced the occurrence of four distinct characteristic periods with very different properties. Steady oxic conditions were characterised by oxygen consumption rates between 10 and 40 mu mol L-1 h(-1), dissolved inorganic carbon (DIC) production of 9-12 mu mol L-1 h(-1), very low NE4+ and Mn2+ concentrations, and constant NO3 production rates (0.4 - 0.7 mu mol L-1 h(-1)) due to coupled ammonification and nitrification. The beginning of anoxic periods (24 h following oxic to anoxic switches) showed DIC production rates of 2.5-8.6 mu mol L-1 h(-1) and very fast NO consumption (5.6-6.3 mu mol L-1 h(-1)) and NH4+ production (1.4-1.5 mu mol L-1 h(-1)). The latter rates were positively correlated to NO concentration and were apparently caused by the predominance of denitrification and dissimilatory nitrate reduction to ammonia. Steady anoxic periods were characterised by constant and low NO3- concentrations and DIG and NH4+ productions of less than 1.3 and 0.1 mu mol L-1 h(-1), respectively. Mn2+ and CH4 were produced at constant rates (respectively 0.3 and 0.015 mu mol L-1 h(-1)) throughout the whole anoxic periods and in the presence of nitrate. Finally, reoxidation periods (24-36 h following anoxic to oxic switches) showed rapid NH4+ and Mn2+ decreases to zero (1.6 and 0.8-2 mu mol L-1 h(-1), respectively) and very fast NO production (3 mu mol L-1 h(-1)). This NO3- production, together with marked transient peaks of dissolved organic carbon a few hours after anoxic to oxic switches, suggested that particulate OM mineralisation was enhanced during these transient reoxidation periods. An analysis based on C and N mass balance suggested that redox oscillation on short time scales (day to week) enhanced OM mineralisation relative to both steady oxic and steady anoxic conditions, making ETMs efficient biogeochemical reactors for the mineralisation of refractory terrestrial OM at the land-sea interface.
