Characterization of a novel population of low-density granulocytes associated with disease severity in HIV-1 infection

2012

The mechanisms resulting in progressive immune dysfunction during the chronic phase of HIV infection are not fully understood. We have previously shown that arginase, an enzyme with potent immunosuppressive properties, is increased in HIV seropositive (HIV+) patients with low CD4(+) T cell counts. Here we show that the cells expressing arginase in peripheral blood mononuclear cells of HIV+ patients are low-density granulocytes (LDGs) and that whereas these cells have a similar morphology to normal-density granulocyte, they are phenotypically different. Importantly, our results reveal that increased frequencies of LDGs correlate with disease severity in HIV+ patients.

The Third Competition for Ernesto Basile’s Palace of Justice. Analysis, Conjectural Reconstruction and Photo Insertions

2022

The competition for the Palazzo di Giustizia in Rome takes place in four phases that develop between 1884 and 1887. The project of the third competition (1886-1887), drawn up by Ernesto Basile (Palermo 1857-1932), reveals a great maturity design that transforms the complex functional program into a rigorous neo-Renaissance style building. The jury recognizes the quality of the project and selects it for the final phase by invitation (1887) together with that one of Guglielmo Calderini, who will be the winner. The original drawings of the unrealized work are kept at the Basile Endowment of the Department of Architecture of the University of Palermo: among them there are sketches, preparatory…

Anti-HIV-1 activity of inorganic polyphosphates.

1997

Human blood plasma, serum, peripheral blood mononuclear cells, and erythrocytes contain significant amounts of inorganic polyphosphates (ranging from 53 to 116 microM, in terms of phosphate residues). Here we demonstrate that at higher concentrations linear polyphosphates display cytoprotective and antiviral activity. Sodium tetrapolyphosphate and the longer polymers, with average chain lengths of 15, 34, and 91 phosphate residues, significantly inhibited human immunodeficiency virus type 1 (HIV-1) infection of cells in vitro at concentrations > or = 33.3 microg/ml (> or = 283-324 microM phosphate residues), whereas sodium tripolyphosphate was ineffective. In the tested concentration range,…

L’immaginario custodito. Catalogo delle raccolte 1-2-3 dell’Archivio etnofonico del Folkstudio

2009

The essay contains the catalog of sound recordings relating to field surveys conducted from 1966 to 1970, constituting the first collections of the Ethnophonic Archive of the Folkstudio of Palermo, formed thanks to the initial donation of Elsa Guggino and implemented with the researches of his students.

From the South. Ernesto Basile's Routes and Destinations

2014

Except for a few gaps, the Basile's archive is one of the best maintained contemporary architectural archives in Europe. Basile wrote extensively about his travels and discussed their context and significance. The documents range from reports on the World Exhibition in Paris in 1878, to stories of Ortensio Lando, the sixteenth-century Italian humanist and traveler, who moved "from the far Sicily to the edge of the Alps".

Un ponte ancora aperto? Alcune note sull’emigrazione siciliana verso gli Stati Uniti durante il fascismo

2018

During the 1920s, after the promulgation by US government of the Quota Acts, and after the new fascist policies about emigration in Italy (1926), we register a dramatic decrease of the transatlantic migration flows from Italy to the US. Focusing on the case of Sicily, one of the region which had sent more emigrants to the US during the Great Migration, this essay analyses the issue of migratory waves from Southern Italy to the US during the Fascism. In fact, despite of the reshaping of migration policies, some traditional networks between Sicily and America are still working. For example, some new researches about transnational Mafia reveal the existence of dynamic Sicilian-American network…

Schistosomiasis and water-related practices in school girls in rural KwaZulu-Natal, South Africa

Science, politics and image in Valencia: a review of urban discourse in the Spanish City

2003

Abstract In the urban sphere, discourse is fundamental to the social and political construction of urban reality. The urban landscape is, in part, a result of those discourses. It is, as Richard Schein suggests, a discourse materialized. The production of these discourses throughout urban history both represented and constructed urban reality at any given time. For much of history, the written word was central to such discursive representations, literary formulations and even biological metaphors that sought to interpret the city both for local inhabitants and outsiders. Today, the photographic image has usurped the former dominance of the word. This article uses archival research to trace …
