Dynamics of fungal colonization in a new medical mycology laboratory
2012
International audience; Objective of the study. - Study of the spatio-temporal fungal colonization in a new medical mycology laboratory. Methods. - A 17-month survey of airborne fungal contamination was conducted in a new medical mycology laboratory at a tertiary care university hospital. This survey was implemented at three different periods: before the new premises were occupied (period A), during the move into the new laboratory (period B) and after resumption of the mycological activities in these new premises (period C). Results. - During period A, the airborne fungal load ranged from 2.3 to 6 cfu/m(3). The most frequently recovered airborne fungi were Penicillium spp. (75 to 100%). Du…
Antifungal effect of engineered silver nanoparticles on phytopathogenic and toxigenic Fusarium spp. and their impact on mycotoxin accumulation.
2019
Abstract Cereal grains are essential ingredient in food, feed and industrial processing. One of the major causes of cereal spoilage and mycotoxin contamination is the presence of toxigenic Fusarium spp. Nanoparticles have immense applications in agriculture, nutrition, medicine or health but their possible impact on the management of toxigenic fungi and mycotoxins have been very little explored. In this report, the potential of silver nanoparticles (AgNPs) (size 14–100 nm) against the major toxigenic Fusarium spp. affecting crops and their effect on mycotoxin accumulation is evaluated for the first time. The studied Fusarium spp. (and associated mycotoxins) were F. graminearum and F. culmor…
Coronal properties of G-type stars in different evolutionary phases
2005
We report on the analysis of XMM-Newton observations of three G-type stars in very different evolutionary phases: the weak-lined T Tauri star HD 283572, the Zero Age Main Sequence star EK Dra and the Hertzsprung-gap giant star 31 Com. They all have high X-ray luminosity (10^31 erg/s for HD 283572 and 31 Com and 10^30 erg/s for EK Dra). We compare the Emission Measure Distributions (EMDs) of these active coronal sources, derived from high-resolution XMM-Newton grating spectra, as well as the pattern of elemental abundances vs. First Ionization Potential (FIP). We also perform time-resolved spectroscopy of a flare detected by XMM from EK Dra. We interpret the observed $EMD$s as the result of …
Il paesaggio agrario nella Sicilia ellenistico-romana: Alesa e il suo territorio
2008
La ricostruzione del sistema del popolamento rurale e dei modi di sfruttamento delle risorse, all’interno di un comprensorio geograficamente e storicamente determinato, costituisce l’oggetto della ricerca storico-topografica condotta sul territorio di Alesa. L’area di studio è centrata intorno alla città di Alesa, che ne rappresenta il fulcro, storico e geografico insieme, con l’obiettivo di tracciare il rapporto tra centro urbano e territorio circostante, fonte primaria dei mezzi di sussistenza. L’orizzonte cronologico è però più ampio, spaziando da età preistorica al tardo-antico, con la consapevolezza che alcune forme dell’insediamento, insieme ad aspetti riguardanti sia la disponibilità…

Vanadium‐Doped Zircon and Zirconia Materials Prepared from Gel Precursors as Site‐Selective Electrochemical Sensors
2003
Abstract Polymer film electrodes incorporating vanadium‐doped zircon (V x ZrSiO4, 0.00 < x < 0.10) and vanadium‐doped monoclinic and tetragonal zirconias (V x ZrO2, 0.00 < x < 0.15), prepared by heat treatment of gel precursors, exhibit a significant site‐selective electrocatalytic activity towards the oxidation of amino acids, polyalcohols, and polyhydroxycarboxylic acids in alkaline media. Catalysis of the oxidation of carboxylate and alcohol groups involves a relatively slow chemical reaction between the substrate and vanadium centers, while the oxidation of thiolate in cysteine can be attributed to the oxidation of an adduct formed by vanadium centers and the substrate.

Calcium binding and ionic conduction in single conical nanopores with polyacid chains: model and experiments.
2012
Calcium binding to fixed charge groups confined over nanoscale regions is relevant to ion equilibrium and transport in the ionic channels of the cell membranes and artificial nanopores. We present an experimental and theoretical description of the dissociation equilibrium and transport in a single conical nanopore functionalized with pH-sensitive carboxylic acid groups and phosphonic acid chains. Different phenomena are simultaneously present in this basic problem of physical and biophysical chemistry: (i) the divalent nature of the phosphonic acid groups fixed to the pore walls and the influence of the pH and calcium on the reversible dissociation equilibrium of these groups; (ii) the asym…
Formazione alla generatività, nella vita coniugale e nella relazione genitoriale. Riflessioni pedagogiche e orientamenti educativi
2014
L’autore tiene presente l’ultimo Rapporto CISF 2001 sulla famiglia in Italia, dedicato alle relazioni di coppia. L’attenzione, in particolare, è rivolta ad un fenomeno emergente, quello delle coppie che scelgono di restare childfree. Viene condotta una riflessione di antropologia pedagogica secondo lo stile fenomenologico, intesa a evidenziare le intenzionalità strutturali della dinamica di una coppia, quella amorosa, quella oblativa e quella sponsale. Qualsiasi scelta fatta dai partner, la convivenza, il matrimonio con rito civile o lo sposalizio con rito religioso, è segnata da queste intenzionalità originarie e dalla loro tensione intimamente generativa. Su questa base, l’autore definisc…
