De la performance musicale dans la Guyane traditionnelle : expression cognitive singulière d?une musique-verbe
2021
Guianese culture and traditional music, here evoked, are various. It is more a transcultural process that, along centuries, gave an original result born in the Americas, in Guiana in this case. It is a form of refoundation, of recreation of cultures and new human beings generally called Creoles. The musical performance, that I study here, is the echo of social and cultural space of this reformulation of thought, life, and conception of the world. It is, as well, a mean of transposition and transformation of the values issued of diverse sources and categories. It is in no way a second-rate cultural practice, as it is the place where were born philosophies and actions for common life as well …
A multiphase multiobjective dynamic genome-scale model shows different redox balancing among yeast species of the saccharomyces genus in fermentation
2021
Yeasts constitute over 1,500 species with great potential for biotechnology. Still, the yeast Saccharomyces cerevisiae dominates industrial applications, and many alternative physiological capabilities of lesser-known yeasts are not being fully exploited. While comparative genomics receives substantial attention, little is known about yeasts’ metabolic specificity in batch cultures. Here, we propose a multiphase multiobjective dynamic genome-scale model of yeast batch cultures that describes the uptake of carbon and nitrogen sources and the production of primary and secondary metabolites. The model integrates a specific metabolic reconstruction, based on the consensus Yeast8, and a kinetic …
Introduction du séminaire. SEBIOPAG-PHYTO déterminants agricoles parcellaires et paysagers des variations de niveaux de régulation biologique
2017
Prod 2017-344b SPE équipe EA GESTAD INRA; National audience; Le niveau de compréhension des processus écologiques et de leurs interactions avec les activités agricoles est insuffisant pour que les agriculteurs mobilisent ou intègrent la biodiversité et ses services dans leurs décisions de gestion. En effet, la plupart des études portent sur la biodiversité taxonomique et peu sur la régulation biologique. Elles considèrent les activités agricoles à un grain grossier et à l’échelle annuelle, d’où une impossibilité d’identifier des modalités de conduite technique des exploitations agricoles utiles pour renforcer les régulations biologiques. En parallèle, l’intégration de résultats scientifique…
Streptomyces coelicolor secretoma protects astrocytes from oxidative stress
2016
Streptomycetes are gram-positive bacteria that produce about 2/3 of pharmaceutically active secondary metabolites, such as antibiotics, and anti-tumor, immunosuppressive, antifungal and antiparasitic agents. In this study, we investigated the possible effects of Streptomyces coelicolor extracts and putative vesicular fraction on primary cultures of rat astrocytes, in both physiological and stressed conditions, induced by treatment with hydrogen peroxide. Briefly, crude extracts and putative vesicular fractions were prepared from two S.coelicolor strains (M145 wild-type strain and bold F166 strain), and used to treat primary astrocytes, which were then also treated with hydrogen peroxide. Da…
Diversité et déterminisme génétique de l’aptitude du pois protéagineux (Pisum sativum) à la culture associée avec le blé (Triticum aestivum).
2018
National audience; Les cultures en association avec des légumineuses sont aujourd’hui une des voies privilégiées pour développer une agriculture plus respectueuse de l’environnement. En effet, stabilisation de la qualité et de la productivité de la parcelle, diminution des apports azotés, meilleure gestion des adventices et pathogènes, meilleure nutrition des deux partenaires et augmentation de la diversité microbienne du sol sont autant de services éco-systémiques attendus vis-à-vis de ce type de culture. Cependant, peu de travaux ont porté sur l’aptitude génétique à l’association du pois avec d’autres espèces et notamment le blé, alors que nous disposons désormais d’outils de phénotypage …
Are virtues national, supranational, or universal?
2014
Many studies investigated cultural differences in values, most notably by Hofstede and Schwarz. Relatively few have focused on virtues, a related and important concept in contemporary social science. The present paper examines the similarities and differences between nations, or blocks of - culturally related - nations on the perceived importance of virtues. Adults (N = 2.809 students) from 14 countries were asked to freely mention which virtues they found important to practice in daily life, and next to rate a list of 15 virtues, which reflect the most frequently mentioned categories in The Netherlands, as found in a previous study. The 14 nations included the United States, Mexico, nine E…
A 3D‑scaffold of PLLA induces the morphological differentiation and migration of primary astrocytes and promotes the production of extracellular vesi…
2019
The present study analyzed the ability of primary rat astrocytes to colonize a porous scaffold, mimicking the reticular structure of the brain parenchyma extracellular matrix, as well as their ability to grow, survive and differentiate on the scaffold. Scaffolds were prepared using poly-L-lactic acid (PLLA) via thermally-induced phase separation. Firstly, the present study studied the effects of scaffold morphology on the growth of astrocytes, evaluating their capability to colonize. Specifically, two different morphologies were tested, which were obtained by changing the polymer concentration in the starting solution. The structures were characterized by scanning electron microscopy, and a…
Il Paradigma della Città Fluida
2013
Nella recente crisi globale i poderosi flussi di capitali finanziari, sociali e relazionali che hanno alimentato la riqualificazione urbana nel corso degli ultimi quindici anni non sono più disponibili ad essere intercettati in maniera indiscriminata così come è stato possibile fino a qualche anno fa. Nell'era della crisi strutturale le città più dinamiche non sono più quelle in grado di attrarre progetti urbani iconici ed investitori spinti dal mercato immobiliare o dalla redditività delle attività ricreative, ma quelle città che, a partire dalle loro profonde e diversificate risorse culturali, saranno capaci di attuare una vera e propria “metamorfosi” per usarle come base per la creazione…
Résistance aux inhibiteurs de l’ALS chez le séneçon commun (Senecio vulgaris) : la situation en vigne et en grandes cultures
2016
Resistance to ALS-inhibiting herbicides in common groundsel (Senecio vulgaris) : situation in franch vineyards and major field crops. Common groundsel (Senecio vulgaris) is a ubiquitous weed that is highly mobile and which seeds can germinate almost all year long. It also is the only weed species today in France that is officially acknowledged to have evolved a resistance to one same herbicide mode of action both in vineyards and major field crops. The purpose of this paper is to provide a picture of a few major aspects of this resistance: underlying mechanisms, detection, seed viability, spread and geographical extent of the resistance.
