    editorial reviewedPulmonary hypertension (PH) is a common clinical condition linked to chronic cardiopulmonary illnesses. It must be distinguished from pulmonary arterial hypertension (PAH), a rare disease characterized by a specific involvement of the pulmonary arterial bed. An early diagnosis and accurate classification by a multidisciplinary team are necessary for a multimodal and individualized therapy approach. This article aims to provide a summary of the most recent ESC/ERS recommendations published in 2022.L’hypertension pulmonaire (HTP) est une entité clinique fréquemment retrouvée chez les patients atteints d’affections cardio-pulmonaires chroniques. Elle est à différentier de l’hypertension artérielle pulmonaire (HTAP) qui est, quant à elle, une maladie rare caractérisée par une atteinte spécifique du lit artériel pulmonaire. Une identification précoce et une classification correcte, en équipe pluridisciplinaire, sont primordiales pour une prise en charge thérapeutique multimodale et personnalisée. Cet article a pour but de résumer, de façon pratique, les dernières recommandations des sociétés européennes de cardiologie (ESC) et de pneumologie (ERS) publiées en 2022

    Molecular and physiological basis of Saccharomyces cerevisiae tolerance to adverse lignocellulose-based process conditions

    Lignocellulose-based biorefineries have been gaining increasing attention to substitute current petroleum-based refineries. Biomass processing requires a pretreatment step to break lignocellulosic biomass recalcitrant structure, which results in the release of a broad range of microbial inhibitors, mainly weak acids, furans, and phenolic compounds. Saccharomyces cerevisiae is the most commonly used organism for ethanol production; however, it can be severely distressed by these lignocellulose-derived inhibitors, in addition to other challenging conditions, such as pentose sugar utilization and the high temperatures required for an efficient simultaneous saccharification and fermentation step. Therefore, a better understanding of the yeast response and adaptation towards the presence of these multiple stresses is of crucial importance to design strategies to improve yeast robustness and bioconversion capacity from lignocellulosic biomass. This review includes an overview of the main inhibitors derived from diverse raw material resultants from different biomass pretreatments, and describes the main mechanisms of yeast response to their presence, as well as to the presence of stresses imposed by xylose utilization and high-temperature conditions, with a special emphasis on the synergistic effect of multiple inhibitors/stressors. Furthermore, successful cases of tolerance improvement of S. cerevisiae are highlighted, in particular those associated with other process-related physiologically relevant conditions. Decoding the overall yeast response mechanisms will pave the way for the integrated development of sustainable yeast cell--based biorefineries.This study was supported by the Portuguese Foundation for Science and Technology (FCT) by the strategic funding of UID/BIO/04469/2013 unit, MIT Portugal Program (Ph.D. grant PD/BD/128247/ 2016 to Joana T.

    La « fabrique » des expositions sur les migrations: Un nouvel objet d’étude

    No full text
    International audiencePorté par des initiatives pionnières dès les années 1980, le traitement muséographique des questions migratoires révèle une dimension collaborative croissante dans la conception des expositions. Ces projets d’expositions ont ainsi élaboré leur propre méthodologie permettant de réunir des chercheurs, des institutions patrimoniales et des associations. En recueillant les témoignages et les traces des parcours migratoires, il s’agit à la fois de faire connaître et reconnaître des histoires de vie à l’échelle locale et de verser ces mémoires au patrimoine commun. Une double tâche sur laquelle repose une véritable démocratie patrimoniale
