Texto completo da fonteThe use of yeasts in industry is inseparable from their ability to be produced and dehydrated. This dehydration process causes various dysfunctions in yeast cells that affect their functionality and viability. In order to protect yeasts from dehydration, food additives are often used as emulsifiers and antioxidants. However, yeasts are able to produce naturally protective substances, such as glutathione (GSH) and trehalose (TRE). In this context, three non-Saccharomyces (NS) strains, belonging to the different genera and species Torulaspora delbrueckii, Metschnikowia pulcherrima and Lachancea thermotolerans, were studied in this thesis. Despite the great interest aroused by their multiple agro-food applications, their dehydration resistance mechanisms associated with the synthesis of GSH and TRE, are currently unknown. This study is ultimately aimed at the formulation of new NS yeast dried strains without any food additives. In a first chapter, the impact of the “reference yeast” Saccharomyces cerevisiae dehydration in a pre-pilot fluidized bed has been correlated with the synthesis of GSH and TRE. It was possible to modulate the culture medium composition in order to optimize cell preservation before, during and after dehydration. In a second chapter, the previously defined conditions were applied to NS yeasts strains in order to understand the effects of dehydration on their microbial functionality. This study demonstrated that GSH plays an important role in NS yeasts protection, depending on the culture and dehydration conditions. In a third chapter, some oxidation resistance phenomena of the three NS strains were studied. It was clearly demonstrated that the susceptibility of cells to oxidative attack was dependent on culture-dehydration conditions and was yeast strain-dependent. Finally, in a fourth chapter, an in-depth biochemical study of the most dehydration-sensitive yeast strain, L. thermotolerans, was performed by synchrotron FTIR micro-spectroscopy. Cells grown in GSM (medium favoring the production of GSH), besides showing a better viability, showed a greater intensity in the spectral bands of lipids CH2 and CH3, associated with the plasma membrane fluidity. In addition, TSM grown cells (TSM is a medium favoring the production of TRE) exhibited a higher protein denaturation, suggested by the intensity of β-sheet peaks, and C=O (lipid oxides) bands correlated with lipid peroxidation. These data can explain the decreased of viability of this strain during production-dehydration process. The fundamental knowledge acquired in this study will be useful to obtain new dehydrated yeast strains without additives and with high performance. It will be useful also to improve the formulation and dehydration methods currently used in industry

Texto completo da fonteThe stake of heritage is its transmission (inheritance from one generation to another). Conservation is a mere tool for transmission. But it may happen that conservation and transmission are in conflict, especially for the so-called living heritage – not only in the biological sense of the word, but all that is defined within time : landscape, city, intangible heritage, and, more or less, any property of heritage value. Living material is changing and even mortal. One can try and conserve a property by making it as strong as possible, without needing anybody to manage it : it is conserved, but not transmitted to new managers. Conversely, transmission often implies a transformation. From examples of heritage landscapes (vineyards, large river, roads, urban river), this research examines which transformations conserve what is intended to be transmitted of a living heritage

Texto completo da fonteSince its creation in 1846 the Smithsonian has followed the evolution of the relations between industrialized and traditional societies, relations that have evolved from domination to respect. By turns showcases, encyclopedias, scientific research centers and places to validate the national ideology, museums had lost the contact with the essence of the object, mostly concerned with its physical appearance, that was often magnified by the techniques of conservation. In the sixties. Cartesian thinking and the elitist education were questioned and, in their practices, curators had to take into account the preservation, as well as the educational role and the ethical dimension of the exhibits. Since then the museal object has no longer been a mere treasure but has enabled visitors to have access to the knowledge of communities in their diversity, it has become a link between rational thinking, beliefs and personal or collective feelings. The 21st century museum should be the memory of the group as well as that of the individual, a dynamic memory stretching between the past, the present and the future. The 140 million objects of the Smithsonian collections can be combined ad infinitum to present the world in different ways. Museography and museology join their competencies so that the multicultural exhibitions may not be a mere juxtaposition of differences but offer an opportunity to share experiences and knowledge
Giraud, Sébastien. "Stratégies de préservation et d'immunoprotection du greffon dans un modèle de transplantation d'îlots pancréatiques". Thesis, Poitiers, 2013. http://www.theses.fr/2013POIT1405/document.
Texto completo da fonteOrgan and tissue transplantation is affected by a shortage of grafts, leading to enlargement of donor criteria. Consequently, these new marginal organs are more susceptible to ischemia-reperfusion injury (IRI). IRI increases primary graft dysfunctions and contributes to increase graft immunogenicity and consequently the occurence of acute and chronic rejection. Our objectives were : firstly, the necessity to limit I/R damages and preserve graft integrity, secondly, the importance to reduce graft immunogenicity and control the graft rejection while maintaining an immunocompetent recipient. To limit IRI we evaluated the new SCOT preservation extracellular type solution containing PEG 20kDa 30g/L in a murine model of pancreatic islets isolation and transplantation. The improvement of conservation with SCOT permitted to maintain the islets integrity and to reduce graft immunogenicity, due to the immunoprotective properties of PEG 20kDa (effects obtained with PEG 20kDa at 10 to 30g /L). In this same model our second objective was to establish a peripheral immunological tolerance of the graft by transient depletion of alloreactive T cells. This depletion of T cells in division was induced at the time of islet allotransplantation by an administration of an inducible nucleosidic analogue during 14 days. Transient alloreactive T cells depletion induced a dominant immunotolerance marked by the emergence of a persistent regulatory T cells CD4+CD25+FoxP3+ population. Thus, regulation of homeostatic balance between effector and regulatory T cells could open an interesting way to control the immune reaction against allograft

Texto completo da fonteThe syrian archaeology is developped during the 20th century, from the oldest periods to the medieval and modern ages. This book is at the same time an historiography of this research and a description of its contribution to the preservation and to the presentation as well as to the cultural policy of Syria and its partners. Firstly, this book realizes an analysis of the choice of the sites and their geographical distribution in the various regions of the country. Some of them were privileged, from the lime-stone northern syria to the basaltic country of Hauran in the south. The middle-Euphrates led to many missions for all the periods: Mari in the east, Ebla in central Syria. Palmyra and its steppes also led to many ancient and islamic researches. But, why other regions are neglected? For each case, starting from the map of the studied sites, this study analyse which period an which type of monuments each decade has studied but also which place was researched to a diachronic prospect from early pagan antiquity to Islam. In parallel, the used mode of search and strategies appears, from the excavation of an urban or rural complex, to regional prospections and the archaeology of planning and landscapes? How did we pass from collecting antiques to a true history of the "modes" of archaeology. The second part of the thesis studies the valorization of the heritage. Which policy of conservation and presentation did the study of the sites product? But also, which museographic policy did it contribute to this valorization of researchs and its results: from the Museum of Damascus to that of Palmyra, for exemple, an obvious evolution appears: its principles are analyzed. This book tries to give a clear idea of the evolution of research and of the patrimonial and museologic policy
