Lilibeo al tempo di Cicerone
2021
The volume that sees the light today is the fruit of the Study Day on "Lilibeo at the time of Cicero" held in Marsala, in the conference room of the Museo Lilibeo, on 3 May 2019 thanks to the joint effort of the Museum and the Culture and Society Department of the University of Palermo. In the short term, important changes in the council organizational structure, they led to the establishment of the Archaeological Park of Lilibeo including in a unitary structure the Lilibeo Regional Archaeological Museum, the archaeological area of Capo Boeo, which represents the main nucleus, and other state-owned archaeological areas of the urban fabric of Marsala.
Riflessioni sull’iconografia funeraria lilibetana nell’età di Cicerone
2021
Twenty-four, and possibly twenty-five painted stelae and aediculae were found, in different times, in the area of the necropolis of Lilybaeum (1903, 1974-1984), and further North, nearer to the ancient sea-shore (1895); most recently, two new entries enhanced the Museo Lilibeo (2009), beside two elements from decorated epitymbia. Despite previous scholarly opinions spread these artifacts over three centuries, as a whole, they can be assigned approximately to Cicero’s time. Some cross-cutting features, as a matter of fact, connect the stelae and the “Salinas” aediculae, and indicate that both date between the late 2nd and the late 1st century BC. Nevertheless, they constitue two neatly diffe…
L'età ellenistica
2016
Nel presente capitolo si analizzano le teorie linguistiche delle tre principali scuole filosofiche di età ellenistica: Epicurea, Stoica e Scettica. In this chapter we analyze the linguistic theories of the three main philosophical schools of the Hellenistic age: Epicurean, Stoic and Skeptic.
Representaciones sociales a través del lenguaje en la lexicografía hispanoamericana decimonónica
2014
Este articulo parte de una propuesta de analisis relativamente reciente de la primera lexicografia hispanoamericana despues de la independencia, que consiste en asumir una estrecha relacion entre la elaboracion, difusion y recepcion de los primeros diccionarios del espanol americano –en cuanto produccion cultural de la elite criolla–, y los procesos historicos y socio-politicos de la epoca. Sobre esta base, se postula la existencia de una unidad del discurso lexicografico, a pesar de la diversidad de obras y autores, que es posible entrever y caracterizar. Se analizan, en consecuencia, los mecanismos que en este discurso se ponen en funcionamiento para ofrecer representaciones sociales –en …
Cis-15 intermediates of biohydrogenation in the duodenal flow of cows receiving linseed
2006
Duodenal samples from a previous experiment (Akraim et al., 2006) were reanalysed for determination of cis-15 intermediates of ruminal biohydrogenation (BH). Three dry Holstein cows fitted with a duodenal cannula received a diet with 14% (dry matter basis) raw linseed. C18 fatty acids (C18FA) represented 6.3% of dietary dry matter, and contained 57.8% of C18:3. After 18 days adaptation, on each cow, twelve samples of duodenal flow were taken over 3 days, composited, and analysed for FA composition. Cis-9,trans-11,cis-15C18:3 and trans-11,cis-15C18:2 (CLnA) were identified by GC-MS. The proportion of CLnA was low, in spite of the high C18:3 intake. The first step of C18:3 BH, isomerisation t…
Purification of hydroperoxide lyase from green bell pepper (Capsicum annuum L.) fruits for the generation of C6-aldehydes in vitro.
2002
The aim of this work was to compare the efficiency of different extracts of hydroperoxide lyase from green bell peppers in producing aldehydes: a crude extract, a chloroplastic fraction, and a purified enzyme were investigated. From a crude extract, the HPO lyase was purified by ion-exchange chromatography with a 22.3-fold increase in purification factor. Analysis by SDS-PAGE electrophoresis under denaturating conditions showed only one protein with a molecular weight of 55 kDa, whereas size-exclusion chromatography indicated a molecular weight of 170 kDa. A maximum of 7500 mg of aldehydes per g of protein was obtained with the purified enzyme within 20 min of bioconversion compared to 392 …
A Polyunsaturated Fatty Acid Diet Lowers Blood Pressure and Improves Antioxidant Status in Spontaneously Hypertensive Rats
2001
gamma-Linolenic acid [GLA, 18:3(n-6)], eicosapentaenoic acid [EPA, 20:5(n-3)] and docosahexaenoic acid [DHA, 22:6(n-3)] have been reported to prevent cardiovascular diseases. However, they are highly unsaturated and therefore more sensitive to oxidation damage. We investigated the effects of a diet rich in these polyunsaturated fatty acids (PUFA) on blood pressure, plasma and lipoprotein lipid concentrations, total antioxidant status, lipid peroxidation and platelet function in spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto rats (WKY). Five-week-old SHR and WKY rats were fed for 10 wk either a diet containing Isio 4 oil or a diet rich in GLA, EPA and DHA (5.65, 6.39 and…
Importance of selenium status in patients with chronic heart failure
2015
Abstract Overactivity of the immune system may be a worthwhile therapeutic target for implementing prognostic improvements. Therefore the impact of lipopolysaccharide (LPS) desensitization on survival may help in the development of novel therapies. An understanding of the pathophysiology of the trace element selenium may complement such approaches, as recent data suggest that inflammatory responses are selenium-dependent.
Hemodynamic changes in splanchnic circulation after orthotopic liver transplantation in patients with liver cirrhosis
2002
Background: Liver cirrhosis increases portal vein pressure and alters the splanchnic circulation. With Doppler sonography, we investigated the hemodynamic changes in the portal vein, superior mesenteric artery, hepatic and splenic arteries and spleen size in a group of patients with end-stage liver disease before and after orthotopic liver transplantation (OLT). Methods: Ten patients (seven male, three female; mean age = 48.8 ± 7.6 years) who underwent OLT for liver cirrhosis mainly associated with hepatitis C virus infection completed the study. The control group consisted of 10 patients matched by sex and age who had no gastroenterologic or vascular diseases. All patients underwent duplex…
Hepatitis C virus - associated B cell non-Hodgkin's lymphoma.
2016
The hepatitis C virus (HCV) infected patients are prone to develop bone marrow or various tissue infiltrates with monoclonal B cells, monoclonal B lymphocytosis or different types of B cell non-Hodgkin's lymphoma (BCNHL), of which the most common are splenic marginal zone BCNHL, diffuse large BCNHL and follicular lymphoma. The association between chronic HCV infection and non Hodgkin's lymphoma has been observed especially in areas with high prevalence of this viral infection. Outside the limitations of some studies that have been conducted, there are also geographic, environmental, and genetic factors that contribute to the epidemiological differences. Various microenvironmental signals, s…
