La nuova retorica dello spazio nell'elegia erotica ovidiana
2008
A study on the symbolic connotations of 'internal' and 'external' space (including urban places, travels and trips, the countryside, Egypt etc.) in Ovid's Amores, Ars Amatoria and Remedia Amoris. In this respect, Ovid is very innovative with respect to Tibullus and Propertius.
Il ritratto più importante. Libri, biblioteche, lettori nella poesia dall'esilio di Ovidio
2021
Nell’elegia 1.7 dei "Tristia", la prima raccolta di versi che Ovidio mette insieme dopo la condanna alla relegazione a Tomi, sul mar Nero, il poeta istituisce una relazione speciale e molto significativa tra la sua "imago", il ritratto, i suoi libri, e i luoghi in cui le opere letterarie sono ospitate, le biblioteche. In un certo senso, invita a riflettere sulla funzione dei "volumina", sulle opere ovidiane che i “libri” contengono e mettono in circolo come spazio della memoria e di dialogo con gli autori. L’elegia di Ovidio esule ha il pregio di mettere sotto la lente tutti questi fenomeni, e di farli interagire con un elemento che crea una tensione interessante nel rapporto con tutti gli …
Tentativi di mediazione con il potere. Ovidio, Germanico e il proemio dei Fasti.
2016
Il contributo scevera i tentativi, da parte di Ovidio, di riallacciare i rapporti con il potere imperiale tramite la mediazione del futuro princeps, Germanico, in quello che per noi risulta il proemio definitivo dei Fasti.
Boccaccio, «Ninfale fiesolano» 309, 5-8: per la storia di un tópos fra tradizione classica e suggestioni medievali
2022
Questa nota, alla luce della lettura e dell’interpretazione di un passo del «Ninfale fiesolano» del Boccaccio (309, 5-8), ripercorre la fortuna del motivo della “reciprocità” amorosa e, in particolare, dell’intimo rapporto che fa sì che “due” giovani innamorati, legati da affinità di costumi, età, bellezza, siano come “una” sola persona. Un motivo molto antico, questo, che affonda le sue radici nella tradizione biblica e nella letteratura classica, e che conoscerà ampia fortuna nel Medioevo latino e volgare. Fra i testi che vengono proposti e analizzati si segnalano, soprattutto, le «Metamorfosi» di Ovidio, l’«Ero e Leandro» di Museo, il «Narcissus», il «Pamphilus», l’«Alda» di Guglielmo di…
MCC1019, a selective inhibitor of the Polo-box domain of Polo-like kinase 1 as novel, potent anticancer candidate
2019
Polo-like kinase (PLK1) has been identified as a potential target for cancer treatment. Although a number of small molecules have been investigated as PLK1 inhibitors, many of which showed limited selectivity. PLK1 harbors a regulatory domain, the Polo box domain (PBD), which has a key regulatory function for kinase activity and substrate recognition. We report on 3-bromomethyl-benzofuran-2-carboxylic acid ethyl ester (designated: MCC1019) as selective PLK1 inhibitor targeting PLK1 PBD. Cytotoxicity and fluorescence polarization-based screening were applied to a library of 1162 drug-like compounds to identify potential inhibitors of PLK1 PBD. The activity of compound MC1019 against the PLK1…
I castella dividicula a Palermo
2013
The water flowing from the tap of our houses accounts for the final step of a long and complicated route beaten by time and man; the latter has always committed himself to making the best of such resource, by testing over time different technological solutions according to the environmental, geographical and cultural conditions of the various territories. Now, a widespread distribution-water system caters for most of the Italian region; in Palermo, however, sights of the relics of an ancient system can still be catched, the castella dividicula. It was a complex network of towers, urns and water towers that assured water distribution to all the urban and rural areas of the city. Today, after…
Differences in berry primary and secondary metabolisms identified by transcriptomic and metabolic profiling of two table grape color somatic variants
2019
ABSTRACTAnthocyanins are flavonoids responsible for the color of berries in skin-pigmented grapevine (Vitis vinifera L.). Due to the widely adopted vegetative propagation of this species, somatic mutations occurring in meristematic cell layers can be fixed and passed into the rest of the plant when cloned. In this study we focused on the transcriptomic and metabolic differences between two color somatic variants. Using microscopic, metabolic and mRNA profiling analyses we compared the table grape cultivar (cv.) ‘Red Globe’ (RG, with purplish berry skin) and cv. ‘Chimenti Globe’ (CG, with a contrasting reddish berry skin color). As expected, significant differences were found in the composit…

Effects of malvidin, cyanidin and delphinidin on human adipose mesenchymal stem cell differentiation into adipocytes, chondrocytes and osteocytes.
2019
Abstract Background Anthocyanidins are plant phytochemicals found at high concentrations in berries, vegetables and flowers. Anthocyanidins have been extensively investigated due to their antioxidative, antidiabetic and anti-inflammatory effects. Few studies show that anthocyanidins decrease obesity and improve bone density. However, the effects of anthocyanidins on tissue regeneration have not been sufficiently clarified. Human mesenchymal stem cells (MSCs) are multipotent adult stem cells responsible for the regeneration of fat, bone and cartilage. Although MSCs are often used for screening of biologically active compounds, so far, the effect of anthocyanidins on MSC differentiation has n…
The influence of the solvent's mass on the location of the dividing surface for a model Hamiltonian
2019
The Transition State dividing surface is a key concept, not only for the precise calculation of the rate constant of a reaction, but also for the proper prediction of product ratios. The correct location of this surface is defined by the requirement that reactive trajectories do not recross it. In the case of reactions in solution the solvent plays an important role in the location of the dividing surface. In this paper we show with the aid of a model Hamiltonian that the effective mass of the solvent can dramatically change the location of the dividing surface.
