Concept of dynamic DNA network dedicated to DNA-Protein interactions studies
2007
The approach lies on the development of an original DNA biosensor. This self-assembled DNA biochip is constituted of a tethered lipid membrane presenting « protein/DNA » complexes. This unique assembly, using a highly flexible bifunctional molecular spacer and a fluidic matrix, allows the control of oligonucleotides surface density and their mobility thus favouring hybridization of the DNA probes in liquid environment and under weak constraints. Recent Surface Plasmon Resonance experiments lead to building of protein/DNA dimers presenting two special DNA sequences recognized by regulation proteins. We demonstrated the capacity and relevance of this biosensor in the case of an estrogen recep…
Import of norovirus infections in the Netherlands and Ireland following pilgrimages to Lourdes, 2008--preliminary report.
2008
International audience; Between mid-September and 19 October 2008, nine clusters of norovirus infection involving around 90 primary cases and over a hundred secondary cases were identified in patients from the Netherlands, Ireland, Italy and France, linked to pilgrimage to Lourdes, France.
" LIVING TOGETHER " PREVENTION WORKSHOPS ON RADICALIZATION IN PRISON SETTING
2016
International audience; We aim to introduce a field action set up in the prison field following the Paris attacks (07/01/2015) in order to create a talking and thinking space for new arrivals in jail. This action, based on prevention workshops (N=7), has been hosted each time by a probation officer and a psychologist, allowing about forty incarcerated men to think about each one's place as a citizen. We used intergroup relations framework, specifically of social categorization metatheory (Abrams & Hogg, 2004; Tajfel & Turner, 1979, 1986; Turner et al., 1987), supplemented by theory of social partitions (Castel & Lacassagne, 2011, 2015). The methodology is based on empathy in relationship, i…
Alternaria Mycotoxins in Food and Feed: An Overview
2017
Alternariais one of the major mycotoxigenic fungal genera with more than 70 reported metabolites.Alternariamycotoxins showed notably toxicity, such as mutagenicity, carcinogenicity, induction of DNA strand break, sphingolipid metabolism disruption, or inhibition of enzymes activity and photophosphorylation. This review reports on the toxicity, stability, metabolism, current analytical methods, and prevalence ofAlternariamycotoxins in food and feed through the most recent published research. Half of the publications were focused on fruits, vegetables, and derived products—mainly tomato and apples—while cereals and cereal by-products represented 38%. The most studied compounds were alternario…
Secondary metabolites of the lichen-associated fungus Apiospora montagnei
2017
Abstract The endolichenic fungus Apiospora montagnei isolated from the lichen Cladonia sp. was cultured on solid rice medium, yielding the new diterpenoid libertellenone L (1), the new pyridine alkaloid, 23-O-acetyl-N-hydroxyapiosporamide (2) and the new xanthone derivative 8-hydroxy-3-hydroxymethyl-9-oxo-9H-xanthene-1-carboxylic acid methyl ether (3) together with 19 known compounds (4–22). The structures of the new compounds were elucidated by 1D and 2D NMR spectra as well as by HRESIMS data. The absolute configuration of the new 6,7-seco-libertellenone derivative 1 was determined by single-crystal X-ray diffraction. Four additional known compounds 23–26 were isolated when NaCl or NH4Cl w…
New umbelliferone sesquiterpene ethers from roots ofLigularia persica
1991
An extract of roots of Ligularia persica yielded thirteen umbelliferone sesquiterpene ethers, among them the new ones ligupersin A (11) and ligupersin B (13).
Semisynthetic roxburghin tetramethyl ether
2008
The title molecule, (E)-2,3′,4,5-tetramethoxystilbene, C18H20O4, is virtually planar. The angle between the two benzene rings is 4.06 (6)°. The intermolecular interactions present in the structure are weak. There are C—H...O hydrogen bonds and C—H...π-electron ring interactions. The molecules are ordered into planes that are parallel to (overline{1}01). The distance between adjacent planes is about 3.3 Å and therefore π–π electron interactions between the aromatic planes are also plausible.
