Copper binding capacity of root exudates of cultivated plants and associated weeds
2001
International audience; Cu binding to root exudates of two cultivated plants, wheat (Triticum aestivum) and rape (Brassica napus), and two weeds associated with wheat, dog daisy (Matricaria inodora) and cornflower (Centaurea cyanus), was studied in vitro under hydroponic and sterile conditions. Nutrient solutions were prepared with or without P. A MetPLATE microbiological test was used to assess the metal complexing capacity of root exudates. In the P-deficient solutions, no exudation was observed for any of the four plants; consequently, no Cu binding occurred. When P was present in the nutrient solutions, the plant exudates displayed differing abilities to complex Cu. No difference was de…
Inquiétants dépaysements. Les voyages mélancoliques de Germaine de Staël (1803-1814)
2016
The Coppet group, a circle of thinkers around 1800, put displacement and the crossing of borders at the heart of its productions. Born out of a sense of national disaffiliation, the group plays a founding experimental role for the consciousness of the subject in travel narratives. Soliciting travel as much in the exploration of a country as in philosophy and knowledge, Germaine de Staël's De l'Allemagne is both a travel narrative and a metaphysical breviary. In a tone close to autobiography, the author observes an inner region rather than a foreign country.
Crémations et monument funéraire campaniformes à Genlis « le Nicolot » (Côte-d'Or, France)
2021
The building of the high-speed rail track linking the Rhine to the Rhone led to the discovery of two Bell Beaker burials in an Iron Age cemetery located in the plain to the east of Dijon. The Tilles plain is an alluvial environment, shaped by the valleys of the Tille and the Ouche and populated since Late Prehistory, particularly during the Bell Beaker and Early Bronze periods, which have yielded settlements located on the rivers. These burials are the first funerary features discovered in the area.The two Bell Beaker cremation burials excavated at Genlis "le Nicolot" are remarkable, as still too little is known of the funerary practices of the period in the east of France and in particular…

Electrochemistry of Bis(pyridine)cobalt (Nitrophenyl)corroles in Nonaqueous Media
2018
International audience; A series of bis(pyridine)cobalt corroles with one or three nitrophenyl groups on the meso positions of the corrole macrocycle were synthesized and characterized as to their electrochemical and spectroscopic properties in dichloromethane, benzonitrile, and pyridine. The potentials for each electrode reaction were measured by cyclic voltammetry and the electron-transfer mechanisms evaluated by analysis of the electrochemical data combined with UV-visible spectra of the neutral, electroreduced, and electroxidized forms of the corroles. The proposed electronic configurations of the initial compounds and the prevailing redox reactions involving the electroactive central c…

Cosa sei per me: identità e relazione di coppia in adolescenza
2022
La configurazione relazionale di coppia, soprattutto in adolescenza, sembra declinarsi attraverso un processo di tipo proiettivo; i concetti di identificazione attributiva e acquisitiva possono risultare particolarmente utili nella definizione dei legami amorosi. Al centro della riflessione sul legame di coppia in adolescenza si pone la questione dell’intreccio tra individuazione e relazionalità, ossia della ricerca di una soluzione adattiva tra espressione di sé e accoglienza del partner; la fratria e il gruppo dei pari si situano, in tal senso, in uno spazio intermedio che consente di sperimentare la distanza relazionale, i percorsi di identificazione e i processi proiettivi, agevolando l…
Detoxification of Copper and Chromium via Dark Hydrogen Fermentation of Potato Waste by Clostridium butyricum Strain 92
2022
The accumulation of various types of waste containing both organic and inorganic metal-containing compounds is extremely hazardous for living organisms. The possibility of polymer degradation, biohydrogen synthesis, and metal detoxification via the dark fermentation of model potato waste was investigated. For this purpose, the strict anaerobic strain was isolated and identified as Clostridium butyricum. The high efficiency of dark hydrogen fermentation of potatoes with yield of hydrogen in 85.8 ± 15.3 L kg−1 VSpotato was observed. The copperand chromium salts solutions were added to the culture fluid to obtain the concentrations of 50, 100, and 200 mg L−1 Cu(II) and Cr(VI) in the active pha…
Dipeptides of S-Substituted Dehydrocysteine as Artzyme Building Blocks: Synthesis, Complexing Abilities and Antiproliferative Properties †
2021
Background: Dehydropeptides are analogs of peptides containing at least one conjugate double bond between α,β-carbon atoms. Its presence provides unique structural properties and reaction centre for chemical modification. In this study, the series of new class of dipeptides containing S-substituted dehydrocysteine with variety of heterocyclic moieties was prepared. The compounds were designed as the building blocks for the construction of artificial metalloenzymes (artzymes). Therefore, the complexing properties of representative compounds were also evaluated. Furthermore, the acknowledged biological activity of natural dehydropeptides was the reason to extend the study for antiproliferativ…
