L'irosa eloquenza delle strumae
2013
The aim of this paper is to demonstrate how Cicero in his in Vatinium employs the iconic power of the body of the accused, Vatinius, and its repulsive strumae as a logical tool to support his persuasion strategy, thereby creating an enthymeme based upon the premises provided by the features of the body. This way of reasoning rests upon a strongly oriented and often distorting reading of the physical characteristics of the body in accordance with the physiognomic and pathognomonic doctrines. As a result, the de-formities of Vatinius's body, instead of being used to commend Vatinius, become important elements in Cicero's strategy of belittling his opponent's authority.
Quantum potero voce contendam. La pro Ligario di Cicerone nel giudizio di Quintiliano
2019
The paper analyses one of the last voices of the Ciceronian oratory, the Pro Ligario. After a reconstruction of the context in which the oration was produced, the attention is focused on the reception of the text by Quintilian, who on several occasions in the Institutio oratoria shows particular interest for the multiple problems connected to it, identifying the peculiar characteristics.
Photocatalytic Gas-Solid Propene Hydration and Liquid-Solid Glycerol Dehydration by using Keggin Heteropolyacids Supported on TiO2
2015
Photo)catalytic propylene hydration to 2-propanol and glycerol dehydration to acrolein reactions were carried out by using Keggin heteropolyacids (HPAs) supported on TiO2. Binary materials have been prepared by impregnation of H3PW12O40, H3PMo12O40 and H4SiW12O40, on TiO2 Evonik P25. Moreover, a binary material consisting of H4SiW12O40 and TiO2 was prepared via a hydrothermal treatment and tested for the same reactions. All the materials were characterized by X-ray diffraction (XRD), scanning electron microscopy observations (SEM) coupled with energy dispersive X-rayand (EDX) measurements, diffuse reflectance spectroscopy (DRS), Raman spectroscopy and Fourier transform infrared spectroscopy…
Non nuocere, aiutare, non offendere. Rileggere il De officiis di Cicerone nel conflitto tra prossimi e lontani
2019
Can Cicero’s De officiis be considered as an excuse for justifying and supporting the common idea that rights, aid and solidarity have been reserved only to those are “close” to us? In the current debate concerning the real universality and the value of human rights, the interpretation of the last work of Arpino’s author, framed in its historical and cultural context, may contribute to a fair restitution of the meaning we assume for the virtue named ratio societatis et communitatis.
Il discorso sui 'metalla' fra ideologia, poetica e retorica. Da Cicerone a Prudenzio
2002
L'articolo mira a ricostruire, attraverso un percorso per sondaggi e campioni, l'ampio dibattito sviluppato dalla cultura latina intorno al tema dello sfruttamento delle risorse minerarie in un arco di tempo che va dalla tarda repubblica al V secolo d. C. Analizzando una serie di testi appartenenti ad epoche, generi ed autori diversi (Cicerone, Ovidio, Manilio, Seneca, Lucano, Silio Italico, Tiberiano, Prudenzio) si pone in luce la natura eminentemente etico-culturale, e assai spesso moralistica, dell'interesse mostrato dagli scrittori latini per questo tipo di tematiche. Al contempo, tuttavia, si segnala un significativo slittamento prospettico nelle varie fasi della storia culturale roman…
Serve ancora ucidere i tiranni? A proposito di Ps. Quint. decl. min. 253
2018
The paper deals with Ps. Quint. decl. min. 253; in the text, concerning one of the best-known themes of the declamatory literature, a tyrannicide, after killing a tyrant, asks the community for approval of a rogatio in order to be sent to the tyrant of the nearby city. The declamation focuses on a hero willing to put the salvation of the community before his own, a theme certainly usual in Latin thought, but which traces new interpretative ways in the declamatory culture.
Transcriptional analysis of pha genes in pseudomonas mediterranea CFBP 5447 grown on glycerol
2014
We analysed the draft genome sequence of Pseudomonas mediterranea CFBP 5447 in order to identify firstly the central metabolic pathways that convert fatty acids or carbohydrate intermediates into mcl-PHA and secondly the genes involved in glycerol metabolism (glpF, glpK, glpD, glpR). Absence of the glpF gene, which codifies for the "glycerol uptake facilitator protein", was highlighted. In order to understand the expression of the pha gene cluster, we investigated the promoter activity of phaC1, phaC2, phaZ, phaD and phaI genes. When glycerol was present as the carbon source, PI was found to be the most active promoter. Expression analysis of the knock-out mutant of the phaD gene, which is …
Nanocomplexes for gene therapy of respiratory diseases: Targeting and overcoming the mucus barrier
2015
Gene therapy, i.e. the delivery and expression of therapeutic genes, holds great promise for congenital and acquired respiratory diseases. Non-viral vectors are less toxic and immunogenic than viral vectors, although they are characterized by lower efficiency. However, they have to overcome many barriers, including inflammatory and immune mediators and cells. The respiratory and airway epithelial cells, the main target of these vectors, are coated with a layer of mucus, which hampers the effective reaching of gene therapy vectors carrying either plasmid DNA or small interfering RNA. This barrier is thicker in many lung diseases, such as cystic fibrosis. This review summarizes the most impor…
Cryopreservation of MHC Multimers: Recommendations for Quality Assurance in Detection of Antigen Specific T Cells
2015
Fluorescence-labeled peptide-MHC class I multimers serve as ideal tools for the detection of antigen-specific T cells by flow cytometry, enabling functional and phenotypical characterization of specific T cells at the single cell level. While this technique offers a number of unique advantages, MHC multimer reagents can be difficult to handle in terms of stability and quality assurance. The stability of a given fluorescence-labeled MHC multimer complex depends on both the stability of the peptide-MHC complex itself and the stability of the fluorochrome. Consequently, stability is difficult to predict and long-term storage is generally not recommended. We investigated here the possibility of…
