Students' school‐level symptoms mediate the relationship between a school's observed moisture problems and students’ subjective perceptions of indoor…
2020
Moisture damage can influence the subjective assessment of indoor air quality (subjective IAQ) in various ways. We studied whether the frequency of symptoms reported across students at school level mediates the relationship between observed mold and dampness in a school building and students' subjective IAQ. To answer this research question, we tested a multilevel path model. The analyzed data were created by merging two nationwide data sets: (a) survey data from students, including information on subjective IAQ (N = 24,786 students); (b) data from schools, including information on mold and dampness in a school building (N = 222). After the background variables were adjusted, schools' obser…
Computational Techniques for the Analysis of Small Signals in High-Statistics Neutrino Oscillation Experiments
2020
The current and upcoming generation of Very Large Volume Neutrino Telescopes – collecting unprecedented quantities of neutrino events – can be used to explore subtle effects in oscillation physics, such as (but not restricted to) the neutrino mass ordering. The sensitivity of an experiment to these effects can be estimated from Monte Carlo simulations. With the high number of events that will be collected, there is a trade-off between the computational expense of running such simulations and the inherent statistical uncertainty in the determined values. In such a scenario, it becomes impractical to produce and use adequately-sized sets of simulated events with traditional methods, such as M…
URBANISATION ET RESSOURCE EN EAU : VERS UNE GESTION « DURABLE » ?
2004
International audience; A l'échelle internationale comme sur un plan local, les rapports entre la ville et l'eau se placent dans un nouveau contexte : la prise de conscience de la fragilité de cette ressource, bien collectif et élément indispensable à la vie des sociétés. Or, la croissance urbaine et l'instauration de normes sanitaires plus rigoureuses ont entraîné une multiplication des équipements de circulation, de collecte et de traitement de l'eau dont l'efficacité est mise à mal lors des phénomènes climatiques extrêmes, en dépit de leur coût de plus en plus élevé. Dès lors, des expériences nouvelles en matière de politiques urbaines orientent désormais la gestion de l'eau dans le sens…
Topical anti-inflammatory potential of quercetin in lipid-based nanosystems: In vivo and in vitro evaluation
2013
Purpose: To develop quercetin-loaded phospholipid vesicles, namely liposomes and PEVs (Penetration Enhancer-containing Vesicles), and to investigate their efficacy on TPA-induced skin inflammation. Methods: Vesicles were made from a mixture of phospholipids, quercetin and polyethylene glycol 400 (PEG), specifically added to increase drug solubility and penetration through the skin. Vesicle morphology and self-assembly were probed by Cryo-Transmission Electron Microscopy and Small/Wide Angle X-ray Scattering, as well as the main physico-chemical features by Light Scattering. The anti-inflammatory efficacy of quercetin nanovesicles was assessed in vivo on TPA-treated mice dorsal skin by the d…

Crystal growth and characterization of Zn1-xMgxO advanced micro- and nanostructures
2018
Dentro de la creciente área de investigación de la física de semiconductores, los pertenecientes a la familia II-VI se han convertido en un campo fundamental de la física de materiales debido a que sus propiedades fotofísicas son únicas para crear una nueva generación de dispositivos en el campo de la fotónica y la microelectrónica. Entre ellos, los semiconductores basados en ZnO han ganado un considerable interés en la comunidad científica en parte debido a su alta energía de enlace del excitón (60 meV) la cual es 2.4 veces más alta que la energía térmica a temperatura ambiente. Este hecho puede dar lugar a emisión laser excitónica a temperaturas incluso mayores que la ambiente. Además, gr…
Ravinnetason ja ojituksen vaikutus suokasvillisuuden monimuotoisuuteen ja lajikoostumukseen
2013
Lajistollisessa monimuotoisuudessa on havaittavissa ajallista ja paikallista vaihtelua, joka on jo vuosisatojen ajan innoittanut ekologeja selvittämään lajirikkauden määrittäviä tekijöitä. Muun muassa pinta-alan, elinympäristön heterogeenisyyden, energian ja resurssien saatavuuden sekä erilaisten häiriöiden on havaittu vaikuttavan lajistolliseen monimuotoisuuteen. Osa monimuotoisuuteen vaikuttavista prosesseista on yhä huonosti tunnettuja, ja yksittäisen tekijän vaikutusta voi olla vaikea tulkita, sillä eri tekijät ovat keskenään vuorovaikutuksessa. Tämän tutkimuksen tavoitteena oli selvittää suokasvillisuusyhteisöjen avulla, vaikuttavatko resurssit tai häiriö (1) yhteisön lajimäärään (alfa…
Leishmania tarentolae and Leishmania infantum in humans, dogs and cats in the Pelagie archipelago, southern Italy.
2021
Visceral leishmaniasis (VL) caused by Leishmania infantum is endemic in the Mediterranean basin with most of the infected human patients remaining asymptomatic. Recently, the saurian-associated Leishmania tarentolae was detected in human blood donors and in sheltered dogs. The circulation of L. infantum and L. tarentolae was investigated in humans, dogs and cats living in the Pelagie islands (Sicily, Italy) by multiple serological and molecular testing. Human serum samples (n = 346) were tested to assess the exposure to L. infantum by immunofluorescence antibody test (IFAT), enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) and to L. tarentolae by IFAT. Meanwhile, sera from do…
