Il complesso monastico di Santa Maria Maddalena di Corleone
2019
Le inedite fonti archivistiche indagate del monastero di Santa Maria Maddalena di Corleone hanno permesso di conoscere le committenze delle nobili e facoltose badesse per l’antico complesso benedettino, che miravano a rinnovare, arricchire e ornare gli spazi sacri rivolgendosi ad artisti di chiara fama. Da Tommaso de Vigilia ad Antonello Gagini, ad Antonio Vasquez e ancora a noti marmorarii, stuccatori, intagliatori e argentieri riservando la realizzazione delle opere a ricamo alle abili consorelle della stessa fondazione monastica. Del prezioso patrimonio ricordato dalle carte d’archivio si rintracciano alcune importanti opere, come i preziosi paliotti ricamati arricchiti ora con perline s…

The crystal structure of a 250-kDa heterotetrameric particle explains inhibition of sheddase meprin β by endogenous fetuin-B
2021
Meprin β (Mβ) is a multidomain type-I membrane metallopeptidase that sheds membrane-anchored substrates, releasing their soluble forms. Fetuin-B (FB) is its only known endogenous protein inhibitor. Herein, we analyzed the interaction between the ectodomain of Mβ (MβΔC) and FB, which stabilizes the enzyme and inhibits it with subnanomolar affinity. The MβΔC:FB crystal structure reveals a ∼250-kDa, ∼160-Å polyglycosylated heterotetrameric particle with a remarkable glycan structure. Two FB moieties insert like wedges through a “CPDCP trunk” and two hairpins into the respective peptidase catalytic domains, blocking the catalytic zinc ions through an “aspartate switch” mechanism. Uniquely, the …

Canne al vento (1913)
1999
Il saggio analizza "Canne al vento" di Deledda, in relazione all'orizzonte letterario sia italiano che europeo. The essay analyzes "Canne al vento", the most well-known novel by Grazia Deledda, connecting it to the European literature of the time
Absorption Properties of Metal–Semiconductor Hybrid Nanoparticles
2011
The optical response of hybrid metal-semiconductor nanoparticles exhibits different behaviors due to the proximity between the disparate materials. For some hybrid systems, such as CdS-Au matchstick-shaped hybrids, the particles essentially retain the optical properties of their original components, with minor changes. Other systems, such as CdSe-Au dumbbell-shaped nanoparticles, exhibit significant change in the optical properties due to strong coupling between the two materials. Here, we study the absorption of these hybrids by comparing experimental results with simulations using the discrete dipole approximation method (DDA) employing dielectric functions of the bare components as input…
Pittura del XIX e del XX secolo nel segno del collezionismo siciliano
2020
Il volume offre una ricognizione sul collezionismo in Sicilia e prende in esame, per la prima volta nella sua interezza, una collezione privata proponendo la riscoperta di opere di autori rappresentativi della cultura figurativa italiana del XIX e del XX secolo, tra cui Michele Catti, Ettore De Maria Bergler, Onofrio Tomaselli, Pippo Rizzo, Alfonso Amorelli e Pina Calì. La collezione privilegia la pittura dell’isola ma include anche il pittore non siciliano Giuseppe Amisani e la coppia di bronzi di Antonio Ugo e trova nelle opere "Costumi" di Salvatore Lo Forte del 1839 e "Sogno del carabiniere" di Pippo Rizzo degli anni ’50 i propri limiti cronologici. Questa raccolta privata, per lo più i…
Metalloprotease meprin β is activated by transmembrane serine protease matriptase-2 at the cell surface thereby enhancing APP shedding.
2014
Increased expression of metalloprotease meprin β is associated with fibrotic syndromes and Alzheimer's disease (AD). Hence, regulation of meprin activity might be a suitable strategy for the treatment of these conditions. Meprin β is a type 1 transmembrane protein, but can be released from the cell surface by ectodomain shedding. The protease is expressed as an inactive zymogen and requires proteolytic maturation by tryptic serine proteases. In the present study, we demonstrate, for the first time, the differences in the activation of soluble and membrane bound meprin β and suggest transmembrane serine protease 6 [TMPRSS6 or matriptase-2 (MT2)] as a new potent activator, cleaving off the pr…
