PROCESS AND PRODUCT OPTIMIZATION IN THE ARTISANAL PRODUCTION OF SICILIAN COFFE GELATO

2020

The production of artisan gelato has always been a very important sector for the Italian economy, the aim of this work is to highlight the peculiarity of production in Sicily, in synergy with a young economic reality and the production reality that is expanding Gelateria Cappadonia, Caffè Morettino Srl Palermo and the academic world. The aim of this research is to solve the color change during the production of artisan coffee gelato.

Geminal Imidazolium Salts: A new Class of Gelators

2012

The gelling behavior of some geminal diimidazolium salts was investigated in solvents differing in polarity and hydrogen bond donor ability. The used salts, namely the 3,3'-di-n-decyl-1,1'(1,4-phenylenedimethylene)diimidazolium dibromide [p-Xyl-(decim)(2)][Br](2) (1), the 3,3'-di-n-dodecyl-1,1'(1,4-phenylenedimethylene)diimidazolium dibromide [p-Xyl-(dodecim)(2)][Br](2) (2), and the 3,3'-di-n-dodecyl-1,1'(1,4-phenylenedimethylene)diimidazolium ditetrafluoroborate [p-Xyl-(dodecim)(2)][BF(4)](2) (3), differ in the alkyl chain length and in the anion properties, such as size, shape, and coordination ability. In all cases in which gelation process was observed, the obtained gels were characteri…

Plasma neutrophil gelatinase-associated lipocalin and long-term mortality in patients with acute heart failure and normal renal function

2015

Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as a renal tubular marker for early renal dysfunction [1]. Recent studies highlighted its role in predicting acute kidney injury (AKI) and clinical outcomes in a wide range of cardiovascular diseases [2], [3], [4] and [5]. However, in heart failure (HF), conflicting results have been reported [4], [5], [6] and [7] and some ambiguities still prevail about the prognostic utility of NGAL beyond standard prognosticators and traditional renal biomarkers. We aimed to evaluate the independent ability of serum NGAL for predicting long-term mortality in patients admitted for acute HF (AHF). We prospectively enrolled 206 patients consecuti…

GEL DOSIMETERS FOR RADIOTHERAPY APPLICATIONS: RESULTS OF A “RESEARCH PROJECT OF NATIONAL INTEREST” (PRIN)

2016

Introduction: Gel dosimeters for three-dimensional mapping of radiotherapy doses were introduced at Yale University in the mid-1980’s. Soon after, research and development in this field also started in Italy. Early work was done at the Istituto Superiore di Sanità and at the Universities of Pisa and Milan. Several institutes now collaborate on this topic with the goal of developing new formulations of hydrogel matrices with improved characteristics of stability, sensitivity and spatial resolution compared to those of earlier Fricke-gel and polymer-gel systems. Materials and methods: Contrary to earlier gels based on natural gelling agents, such as porcine skin gelatin and/or agarose, which …

Vanadium Toxicity Monitored by Fertilization Outcomes and Metal Related Proteolytic Activities in Paracentrotus lividus Embryos

2022

Metal pharmaceutical residues often represent emerging toxic pollutants of the aquatic environment, as wastewater treatment plants do not sufficiently remove these compounds. Recently, vanadium (V) derivatives have been considered as potential therapeutic factors in several diseases, however, only limited information is available about their impact on aquatic environments. This study used sea urchin embryos (Paracentrotus lividus) to test V toxicity, as it is known they are sensitive to V doses from environmentally relevant to very cytotoxic levels (50 nM; 100 nM; 500 nM; 1 µM; 50 µM; 100 µM; 500 µM; and 1 mM). We used two approaches: The fertilization test (FT) and …

Water and temperature contribution to the structuration of starch matrices in the presence of flavour.

2016

The effect of hydrothermal treatments and flavours addition on starch structure and its physical properties were studied. Native wheat starch was treated at 2 different hydrations (water-starch ratios: 50/50 and 80/20 g w/w) and temperatures (65 and 85 °C) in the presence of flavours (ethyl hexanoate and 2-hexanone). The freshly prepared samples were subjected to DSC and flavour analysis. Flavour inclusion complex could not be detected by DSC, however the result of flavour analysis proved that there were flavours interactions with starch. Both ethyl hexanoate and 2-hexanone interacted with starch at similar rates. The highest flavour loss was found in the samples at high hydration and heate…

I Cretesi in Sicilia: la proiezione culturale

2011

Si prendono in esame le tradizioni letterarie sul mito di Minosse, Dedalo e Cocalo, mettendole in relazione con le notizie sulla fondazione di Gela. il mito non presenta una marcata valenza identitaria, e non pertanto non può essere inteso come uno strumento utilizzato univocamente dai coloni di origine cretese per rivendicare la preminenza del loro ruolo, rispetto al gruppo di origine rodia, nelle fondazioni coloniali di Sicilia. Le tradizioni mitiche sono state sfruttate da entrambi i gruppi coloniali per proiettare nello sfondo delle vicende eroiche il modello delle relazioni interetniche che si volevano instaurare nell'attualità con le popolazioni non greche di Sicilia gravitanti attorn…
