Synthesis and characterization of a new layered organic-inorganic hybrid nickel(II) 1,4 : 5,8-naphthalenediimide bis-phosphonate, exhibiting canted a…
2008
A new Ni(II) layered hybrid organic-inorganic compound of formula Ni{sub 2}[(NDI-BP)(H{sub 2}O){sub 2}].2H{sub 2}O has been prepared in very mild conditions from N,N'-bis(2-phosphonoethyl)napthalene-1,4:5,8-tetracarboximide (NDI-BP ligand) and NiCl{sub 2}. The X-ray powder structure characterization of the title compound suggests a pillared layered organic-inorganic hybrid structure. The distance between the organic and inorganic layers has been found to be 17.8 A. The inorganic layers consist of corner sharing [NiO{sub 5}(H{sub 2}O)] octahedra and they are pillared by the diphosphonate groups. DC and AC magnetic measurements as a function of temperature and field indicate the presence of 2…
"Nel più fulgido scenario di colori” Goethe e la scoperta del paradiso a Napoli
2017
Dopo avere visitato Roma, nel febbraio del 1787, J.W. Goethe giungeva a Napoli dove: «l’atmosfera si faceva sempre più pura, ormai ci trovavamo in un’altra terra». Nella seconda metà del Settecento, in Europa il poeta di Francoforte rappresentava certamente il massimo fra i divulgatori del mito del paradiso a Napoli e in Campania, ma anche in Sicilia, e dunque nel Meridione d’Italia, sia per la loro rigogliosa e sempre verde natura sia per l’abbondanza delle loro antichità classiche. A Roma Goethe aveva pregustato i frutti di questo paradiso, ma è solo visitando Napoli e il suo territorio che realizza di essere in un altro mondo, totalmente diverso dai paesi del Nord. Il presente saggio ha …
Considerazioni conclusive
2021
Il saggio presenta alcune considerazioni conclusive sulla sezione monografica dedicata a Istituzioni, relazioni e culture politiche nelle città tra stato della Chiesa e regno di Napoli (1350-1500 ca.). I tre autori, adottando un approccio comparativo, riflettono sulla definizione degli spazi nelle due aree confinanti, sulla condizione delle città pontificie e sulle culture politiche e le specificità dei centri urbani considerati nella raccolta.

Loss of life expectancy from air pollution compared to other risk factors: a worldwide perspective
2020
Abstract Aims Long-term exposure of humans to air pollution enhances the risk of cardiovascular and respiratory diseases. A novel Global Exposure Mortality Model (GEMM) has been derived from many cohort studies, providing much-improved coverage of the exposure to fine particulate matter (PM2.5). We applied the GEMM to assess excess mortality attributable to ambient air pollution on a global scale and compare to other risk factors. Methods and results We used a data-informed atmospheric model to calculate worldwide exposure to PM2.5 and ozone pollution, which was combined with the GEMM to estimate disease-specific excess mortality and loss of life expectancy (LLE) in 2015. Using this model, …
Cell of origin markers identify different prognostic subgroups of lung adenocarcinoma
2018
Strong prognostic markers able to stratify lung adenocarcinoma (ADC) patients are lacking. We evaluated whether a six-immunohistochemical markers panel (TTF1, SP-A, Napsin A, MUC5AC, CDX2 and CK5), defining the putative neoplastic “cell of origin,” allows to identify prognostic subgroups among lung ADC. We screened a large cohort of ADC specimens (2003–2013) from Torino Institutional Repository identifying: (i) marker positivity by immunohistochemistry, (ii) main morphological appearance by light microscopy, (iii) presence of “hotspot” mutations of candidate genes by Sequenom technology. To evaluate possible predictors of survival and time to recurrence, uni- and multivariable-adjusted comp…
Effect of oxidative stress on UDP-glucuronosyltransferases in rat astrocytes.
2012
WOS:000309170300003; International audience; The present work reports data regarding effects of an induced oxidative stress on the mainly expressed isoforms of UDP-glucuronosyltransferases (UGTs) in the brain. UGT1A6 and UGT1A7 expression and enzymatic activities toward the 1-naphthol were analyzed in rat cultured astrocytes following the exposure for 48 h to redox-cycling xenobiotic compounds such as quinones and bipyridinium ions. The expression of NADPH:cytochrome P450 reductase and NAD(P)H:quinone oxidoreductase 1 (NQO1) was also investigated. Oxidative stress induced significant deleterious changes in astrocyte morphology, decreased cell viability and inhibited catalytic function of UG…
La "farfalla" e la "regina". Profili di donne tra "la vita reale e il foglio di carta"
2021
This essay explores the crucible that was the 1970s, focusing on some female figures who – between «real life» and «printed word», history and fantasy – played a key role in uncovering customs and societal dynamics. From Eufrosina, via Donna Felice and her rebellious portrait, we reach Maria Sofia Queen of Naples who – as the eccentric main character of an impossible interview – helps outline Sciascia’s ethical tension through this ‘game’ of fictional conversation in the same year Todo modo was published
Naphthalimide imidazolium-based supramolecular hydrogels as bioimaging and theranostic soft materials
2020
1,8-Naphthalimide-based imidazolium salts differing for the alkyl chain length and the nature of the anion were synthesized and characterized to obtain fluorescent probes for bioimaging applications. First, their self-assembly behavior and gelling ability were investigated in water and water/dimethyl sulfoxide binary mixtures. Only salts having longer alkyl chains were able to give supramolecular hydrogels, whose properties were investigated by using a combined approach of fluorescence, resonance light scattering, and rheology measurements. Morphological information was obtained by scanning electron microscopy. In addition, conductive properties of organic salts in solution and gel state we…
Robustness and electrical reliability of AZO/Ag/AZO thin film after bending stress
2017
Abstract The increasing interest in thin flexible and bendable devices has led to a strong demand for mechanically robust and electrically reliable transparent electrodes. Indium doped Tin Oxide (ITO) and Aluminium doped Zinc Oxide (AZO) are among the most employed transparent conductive oxides (TCO) and their reliability on flexible substrates have thus received a great attention. However, a high flexibility is usually achieved at very low thickness, which, unfortunately, compromises the electrical conductivity. Here we report the effects of mechanical bending cycles on the electrical and optical properties of ultra thin AZO/Ag/AZO multilayers (45 nm/10 nm/45 nm) and, for comparison, of AZ…
