Coffee silverskin extract protects against accelerated aging caused by oxidative agents
2016
Nowadays, coffee beans are almost exclusively used for the preparation of the beverage. The sustainability of coffee production can be achieved introducing new applications for the valorization of coffee by-products. Coffee silverskin is the by-product generated during roasting, and because of its powerful antioxidant capacity, coffee silverskin aqueous extract (CSE) may be used for other applications, such as antiaging cosmetics and dermaceutics. This study aims to contribute to the coffee sector’s sustainability through the application of CSE to preserve skin health. Preclinical data regarding the antiaging properties of CSE employing human keratinocytes and Caenorhabditis elegans are col…
Le suppellettili liturgiche dell'Eparchia di Piana degli Albanesi
2007
Il saggio analizza le suppellettili liturgiche d'argento dell'Eparchia di Piana degli Albanesi esposte alla mostra "Tracce d'Oriente", per lo più realizzate da argentieri palermitani del XVIII e XIX secolo. Le opere della liturgia greco-albanese vengono messe a confronto con quelle utilizzate per le celebrazioni di rito latino. The essay analyzes the silver liturgical furnishings of the Eparchy of Piana degli Albanesi exhibited at the exhibition "Tracce d'Oriente", mostly made by silversmiths from Palermo in the 18th and 19th centuries. The works of the Greek-Albanian liturgy are compared with those used for the Latin rite celebrations.
Evaluation of Effects of Various Irrigating Solutions on Chemical Structure of Root Canal Dentin Using FTIR, SEM, and EDS: An In Vitro Study
2022
Background: Sequential chemical application for irrigating a root canal during chemomechanical debridement can affect the dentin microstructure. Understanding the effects of various irrigants on chemical properties of dentin can elucidate their effects on physical properties and thereby explain the higher incidence of structural failure in endodontically treated teeth. This in vitro research aimed to compare and evaluate the effects of three different irrigating solutions on the chemical structure of root canal dentin in extracted human teeth. Methods: Forty-eight extracted single-rooted mandibular premolar teeth were sectioned at the cemento–enamel junction by a diamond disc and were…
New insights into the pathogenesis of Beckwith-Wiedemann and Silver-Russell syndromes: contribution of small copy number variations to 11p15 imprinti…
2011
International audience; The imprinted 11p15 region is organized in two domains, each of them under the control of its own imprinting control region (ICR1 for the IGF2/H19 domain and ICR2 for the KCNQ1OT1/CDKN1C domain). Disruption of 11p15 imprinting results in two fetal growth disorders with opposite phenotypes: the Beckwith-Wiedemann (BWS) and the Silver-Russell (SRS) syndromes. Various 11p15 genetic and epigenetic defects have been demonstrated in BWS and SRS. Among them, isolated DNA methylation defects account for approximately 60% of patients. To investigate whether cryptic copy number variations (CNVs) involving only part of one of the two imprinted domains account for 11p15 isolated…
ANDREA GIACOBBE, UN SELVICOLTORE CHE MERITA DI USCIRE DALL'OBLIO
2021
Andrea Giacobbe, a forester who deserves to get out from oblivion. The scientific production of Andrea Giacobbe, a Sicilian forester who worked in central and northern Italy in the last century, has been revisited. The aim is to highlights how his contribution to botany, forest ecology and forestry has been largely overlooked. He was the protagonist of a lively debate with the greatest for est scientists of his time, he produced 64 papers and books, but above all he proposed many inno vative reforestation techniques that today should be rediscovered and applied.
“Iugalia aurea et argentea et bona mobilia”. Postille documentarie sui Ventimiglia di Gratteri
2019
Numerosi inventari, atti dotali, testamenti e donazioni rintracciati presso l’Archivio di Stato di Palermo permettono di ricostruire la ricchezza e la varietà del patrimonio artistico della famiglia Ventimiglia del ramo di Gratteri. Numerous inventories, doctrinal deeds, wills and donations found at the State Archives of Palermo make it possible to reconstruct the wealth and variety of the artistic heritage of the Ventimiglia family of the Gratteri branch.
Rayleigh-instability-driven dewetting of thin Au and Ag films on indium-tin-oxide surface under nanosecond laser irradiations
2013
Investigations have been carried out on laser-beam-induced nanoparticle (NP) formation in thin (5 nm) Au and Ag films on indium-tin-oxide substrate. After the irradiation the films were observed to break-up into NPs through a dewetting mechanism. This mechanism was investigated as a Rayleigh-instability- driven process. In fact, for each used laser fluence, the resulting Au and Ag NPs' mean size and surface-to-surface mean distance were quantified and correlated between them in the framework of the Rayleigh-instability theory showing an excellent agreement. © The Institution of Engineering and Technology 2013.
Aggiunte al catalogo di Bonaventura Caruso, sacerdote e orafo messinese della seconda metà del ‘700
2011
Il nome di Bonaventura Caruso, sacerdote e orafo messinese, compare per la prima volta intorno agli anni '70 del XVIII secolo. L'autore, attraverso lo studio delle fonti e grazie a un'accurata analisi stilistica, propone l'identificazione e l'attribuzione a Caruso di un gruppo di opere di argenteria sacra prodotta a Messina oggi nei tesori delle Chiese Madri di Geraci Siculo e Mistretta, tutte caratterizzate dalla presenza di forme e motivi decorativi rococò, ma già tendenti al neoclassicismo. The name of Bonaventura Caruso, a priest and goldsmith from Messina, first appears around the 1870s. The author, through the study of sources and thanks to careful stylistic analysis, proposes the ide…

The benedictine church and monastery of Santa Maria Maddalena of Corleone. Works of art and documents
2019
Il lavoro esamina le diverse fasi di costruzione della chiesa e del complesso monastico di santa Maria Maddalena di Corleone, importante centro dell’entroterra siciliano, soffermandosi in particolare all’età moderna. Le inedite fonti archivistiche indagate oltre ad individuare le maestranze impegnate nei lavori fanno emergere importanti artisti. Successivamente si passa all’individuazione delle opere d’arte sacra ancora esistenti mai indagate scientificamente e raccolte insieme per la prima volta. This work examines the different phases of construction of the church and the monastic complex of Santa Maria Maddalena of Corleone, an important centre in the Sicilian hinterland, focusing in par…
