Il Museo dell’Università. Dalla Pinacoteca della Regia Università di Palermo alla Galleria di Palazzo Abatellis
2016
Il catalogo, oltre a presentare le opere esposte in mostra, racconta la storia e il formarsi delle collezioni d'arte palermitane del Museo dell'Università di Palermo dagli inizi dell'Ottocento fino al 1867, quando prenderà vita il Museo Nazionale nella ex casa dei PP. Filippini all'Olivella, censendo globalmente le opere delle diverse donazioni.
Il motivo della “conversione” nel «Gallicanus» di Rosvita di Gandersheim
2017
This paper focuses on the subject of conversion in Hrotsvitha of Gandersheim’s dramatic plays (or «dramatic dialogues») and, chiefly, in the first of them, the Gallicanus. The play is divided in two parts and is entirely founded on hagiograhical sources, regarding some episodes about the conversion of Gallican, emperor Constantine’s commander-in-chief (BHL 3236: Conversio Gallicani principis militiae), and the martyrdom of primicerii John and Paul (BHL 3242: Passio martyrum Iohannis et Pauli). Through a strict analysis of Hrotsvitha’s play’s matter, can be highlighted the different typologies of the conversion’s theme, which involves a spiritual renovation, and the treatment of dramatic plo…
Gerusalemme, il haram al–sarif e le madaris nella Magalla dell'Accademia della Lingua Araba di Damasco
2023
The interest showed by the magalla (review) of the Academy of Arabic Language of Damascus towards the history of Jerusalem and Palestine, and their Islamic institutions, reveals an organic connection between two geographical areas (Syria and Palestine) which has never been lost. The main aim of this contribution is to shed light on some important aspects with regard to the history and the cultural life of Palestine, and especially of Jerusalem, through the analysis of a series of articles which were published in the Magalla at the end of 20th century.
Imprimée de différentes manières: The Gallican Confession and Its Printed Editions (1559?-1561)
2019
This paper analyses the first printed editions of the Gallican Confession (agreed upon at the synod of Paris in May 1559) and formulates a hypothesis on the context in which they were published and disseminated. Analysis is based on abridged editions of the Confession in Latin and in French, printed in Geneva and Strasbourg, and featuring a preface authored by pastor Antoine de Chandieu. Although the ministers assembled in Paris in 1559 promulgated a confession in 40 articles, only 35 articles were included in these editions (which are dated 1559, but were ostensibly printed in the first half of 1560). These editions in 35 articles were abridged versions of the ‘full’ Gallican Confession, a…
COLORECTAL CANCER AND INFLAMMATORY BOWEL DISEASES: EFFECTS ON DIET AND ANTIOXIDANTS
2017
It is well established that oxidative stress is common in inflammatory bowel diseases (IBDs). Accordingly, antioxidants are recommended for treatment. The aim of this study is to compare the effects of antioxidants contained in the various types of tea on symptoms and evolution of IBD and colorectal cancer (CRC). Analysis of the literature revealed that the theaflavin-3, 30-digallate (TFDG) contained in black tea, and epigallocatechin-3-O-gallate (EGCG) contained in green tea have protective effects against oxidative stress. Moreover, these substances are involved in many biochemical processes responsible for inflammation and proliferation of cancer cells. It is documented that both TFDG an…
Intracellular compartmentation and regulation of two shikimate dehydrogenase isoenzymes in Pisum sativum
1974
Summary Pea seeds as well as sprouts and roots contain two isoenzymes of shikimate dehydrogenase. Both isoenzymes can be separated by Polyacrylamide gel electrophoresis as well as through ammonium sulfate fractionation. The molecular weight of both isoenzymes are the same although the net electric charge is different. The Km value for isoenzyme 1 is 3,5 × 10 −4 and the Km value for isoenzyme 2 is 1,67 × 10 −4 M. 3,4-dihydroxybenzoic acid, 3,5-dihydroxybenzoic acid, gallic acid, anthranilic acid and p-methoxycinnamic acid inhibited both isoenzymes competitively. Anthranlic acid showed the largest affinity to both isoenzymes. M-methoxycinnamic acid and m-nitrocinnamic acid inhibited both isoe…
Electromagnetically generated extracorporeal shock waves for gallstone lithotripsy: in vitro experiments and clinical relevance.
1989
. First generation shock wave sources have been proved to disintegrate gallstones effectively, but they require the immersion of the patient's body in a tank of water. A recently developed second generation shock wave source (Siemens-Lithostar, Erlangen, FRG) generates shock waves electromagnetically. It presents several novel features. In particular the waterbath can be omitted and due to lower shock wave pressure general anaesthesia is not required. In vitro studies showed that 36 out of 38 gallstones (11–30 mm in diameter) could be disintegrated. Two concrements resisting lithotripsy were pure white cholesterol stones. Independent of shape, size, and composition (cholesterol or pigment) …
Silicatein: Nanobiotechnological and Biomedical Applications
2009
Silica-based materials are used in many high-tech products including microelectronics, optoelectronics, and catalysts. Siliceous sponges (Demospongiae and Hexactinellida) are unique in their ability to synthesize silica enzymatically. We have cloned the silica-forming enzymes, silicateins, from both demosponges (marine and freshwater sponges) and hexactinellid sponges. The recombinant enzymes allow the synthesis of silica under environmentally benign ambient conditions, while the technical (chemical) production of silica commonly requires high temperatures and pressures, and extremes of pH. Silicateins can be used for the fabrication of highly-ordered inorganic–organic composite materials w…
Role of the strain in the epitaxial regrowth rate of heavily doped amorphous Si films
2008
Solid phase epitaxial regrowth (SPER) of p -doped preamorphized Si was studied by time resolved reflectivity. Strain and dopant concentration were opportunely varied by implanting neutral (Ge) and isovalent (B, Ga) impurities in order to disentangle the two different effects on SPER. Larger SPER rate variations occurred in strained doped Si with respect to undoped samples. The generalized Fermi level shifting model was implemented to include the role of the strain and to fit the experimental data over a large range of temperature for p - and n -type doping. We introduced a charged defect, whose energy level is independent of the dopant species. © 2008 American Institute of Physics.
