Handbook of fruit and vegetable flavors
2010
Acting as chemical messengers for olfactory cells, food flavor materials are organic compounds that give off a strong, typically pleasant smells. Handbook of Fruit and Vegetable Flavors explores the flavor science and technology of fruits and vegetables, spices, and oils by first introducing specific flavors and their commercialization, then detailing the technical aspects, including biology, biotechnology, chemistry, physiochemistry, processing, analysis, extraction, commodities, and requirements for application as food additives. With chapter authors representing more than ten different countries, this handy reference provides a comprehensive view of this evolving science.
Structure-function analysis of peroxisomal ATP-binding cassette transporters using chimeric dimers
2014
Background: Peroxisomal ABC transporters are predicted to function as homodimers in mammals. [br/] Results: ABCD1 interacts with ABCD2. Chimeric proteins mimicking full-length dimers represent novel tools for functional study. Artificial homodimers and heterodimers are functional. [br/] Conclusion: Interchangeability between ABCD1 and ABCD2 is confirmed, but PUFA transport depends on ABCD2. [br/] Significance: For the first time, heterodimers in mammals are proven to be functional.[br/] ABCD1 and ABCD2 are two closely related ATP-binding cassette half-transporters predicted to homodimerize and form peroxisomal importers for fatty acyl-CoAs. Available evidence has shown that ABCD1 and ABCD2 …
Typology of exogenous organic matters based on chemical and biochemical composition to predict potential nitrogen mineralization
2010
Our aim was to develop a typology predicting potential N availability of exogenous organic matters (EOMs) in soil based on their chemical characteristics. A database of 273 EOMs was constructed including analytical data of biochemical fractionation, organic C and N, and results of N mineralization during incubation of soil–EOM mixtures in controlled conditions. Multiple factor analysis and hierarchical classification were performed to gather EOMs with similar composition and N mineralization behavior. A typology was then defined using composition criteria to predict potential N mineralization. Six classes of EOM potential N mineralization in soil were defined, from high potential N minerali…
Marquage de molécules biologiques par des complexes de radiométaux à base de polyamines macrocycliques
2012
This work conducted at the “Institut de Chimie Moléculaire de l’Université de Bourgogne” carries at first on the synthesis of bifunctional chelating agents suitable for the chelation of trivalent radiometals, including indium-111. The greater part of this work was then dedicated to the grafting of a DOTA derivative bifunctional chelating agent on different antibodies or fragments of monoclonal antibodies: trastuzumab (anti-HER2 treatment of breast cancer), cetuximab (anti EGFR, treatment of many cancers, including colorectal cancer) and abciximab (antiplatelet). Particular attention was paid to the characterization of various immunoconjugates. The critical step of this thesis consisted in t…
Chemistry for wine and wine for health: a propaganda film in benefit of french wines at the beginning of the XXth century
2022
La Cinématographie est une merveilleuse méthode d'éducation générale et de formation technique » 1. Pour compléter cette sentence avancée par le Ministère de l'Agriculture en 1928 en introduction d'un ouvrage sur le cinéma agricole, ajoutons qu'en ce début de XX e siècle, le cinéma s'impose aussi comme un nouvel et formidable outil de propagande pour les productions, les méthodes et les institutions agricoles françaises. En effet, dès le début des années 1920, le Ministère de l'Agriculture, en lien avec des scientifiques ou des sociétés privées, se lance dans l'édition cinématographique afin de montrer, sous la forme de documentaires principalement, les multiples facettes qui forment l'agri…
