Improved co-oxidation of β-carotene to β-ionone using xanthine oxidase-generated reactive oxygen species in a multiphasic system

2007

beta-Ionone, an aroma compound exhibiting flower notes, can be obtained from beta-carotene in a cooxidation system utilizing xanthine oxidase-generated reactive oxygen species (ROS). ROS have to be controlled as, although they can give rise to beta-ionone, they may also degrade it. In this work, the biotransformation of beta-carotene into beta-ionone was investigated in systems containing variable proportions of decane to extract beta-ionone before degradation. The use of 50% or 90% decane resulted in increased production yields. Tween 80, which was added to further improve the production, slightly decreased the reactivity of the medium and the extraction of beta-carotene, but increased the…

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…

Dual mode of action of grape cane extracts against Botrytis cinerea

2019

International audience; Crude extracts of Vitis vinifera canes represent a natural source of stilbene compounds with well characterized antifungals properties. In our trials, exogenous application of a stilbene extract (SE) obtained from grape canes on grapevine leaves reduces the necrotic lesions caused by Botrytis cinerea. The SE showed to possess a direct antifungal activity by inhibiting the mycelium growth. The activation of some grapevine defense mechanism was also investigated. H2O2 production and activation of mitogen-activated protein kinase (MAPK) phosphorylation cascades as well as accumulation of stilbenoid phytoalexins were explored on grapevine cell suspension. Moreover, the t…

Tungsten oxide thin films sputter deposited by the reactive gas pulsing process for the dodecane detection

2015

International audience; The DC reactive magnetron sputtering of a metallic tungsten target was performed in an argon + oxygen atmosphere for depositing tungsten oxide thin films. In order to control the oxygen concentration in the films, the reactive gas pulsing process, namely RGPP, was implemented. Rectangular pulses were used with a constant pulsing period T = 16 s whereas the duty cycle α (time of oxygen injection to pulsing period T ratio) was systematically changed from 0 to 100% of T. This pulsing injection of the reactive gas allowed a gradual evolution of the films composition from pure metallic to over-stoichiometric WO3+ɛ’ compounds. These WOx films were sputter deposited on comm…

Àngels domèstics, ciutadanes republicanes, mestresses consumidores: evolució de l'ideal de la feminitat als llibres escolars (1901-1978)

2005

Els ideals de conducta que la societat desitja en cada moment històric es reflecteixen en els llibres escolars. El seu anàlisi diacrònic es permet observar la seva evolució o involució d’acord amb les necessitats polítiques i socials. Aquest és el cas del mite de la feminitat, el qual, al primer terç del segle XX, es concreta en dos: el tradicional, de l’àngel domèstic, la dona burgesa, mare i mestressa, amb una educació d’adornament, i el de la regeneracionista, que es prepara intel·lectualment i professionalment per a bastar-se a si mateixa i servir als altres. L’arribada del règim republicà farà que aquest model evolucione al de ciutadanes republicanes, que gaudeixen d’igualtat de drets …
