Governare Palermo. Storia e sociologia di un cambiamento mancato.
2009
Fra gli anni ottanta e novanta Palermo ha vissuto – come altre città del Sud – una stagione in cui sembrava avviato un profondo cambiamento sociale e politico. Dopo decenni di malgoverno e corruzione, segnati da un’economia debole e assistita e dai condizionamenti della criminalità, la società civile si era mobilitata. Il governo locale, anche per effetto della riforma, tentava di sperimentare un nuovo modello di sviluppo urbano e nuovi rapporti fra politica e società. Il decennio successivo ha visto però frustrate le aspettative di cambiamento: si ricostituiscono un sistema di governo e un rapporto con gli elettori di tipo tradizionale, mentre la città e la sua economia soffrono di vecchi …
Risk of classic Kaposi sarcoma with exposures to plants and soils in Sicily
2010
Abstract Background Ecologic and in vitro studies suggest that exposures to plants or soil may influence risk of Kaposi sarcoma (KS). Methods In a population-based study of Sicily, we analyzed data on contact with 20 plants and residential exposure to 17 soils reported by 122 classic KS cases and 840 sex- and age-matched controls. With 88 KS-associated herpesvirus (KSHV) seropositive controls as the referent group, novel correlates of KS risk were sought, along with factors distinguishing seronegatives, in multinomial logistic regression models that included matching variables and known KS cofactors - smoking, cortisone use, and diabetes history. All plants were summed for cumulative exposu…

Ganciclovir-induced apoptosis in HSV-1 thymidine kinase expressing cells: critical role of DNA breaks, Bcl-2 decline and caspase-9 activation.
2002
Although ganciclovir (GCV) is most often used in suicide anticancer gene therapy, the mechanism of GCV-induced cell killing and apoptosis is not fully understood. We analysed the mechanism of apoptosis triggered by GCV using a model system of CHO cells stably transfected with HSV-1 thymidine kinase (HSVtk). GCV-induced apoptosis is due to incorporation of the drug into DNA resulting in replication-dependent formation of DNA double-strand breaks and, at later stages, S and G2/M arrest. GCV-provoked DNA instability was likely to be responsible for the observed initial decline in Bcl-2 level and caspase-9/-3 activation. Further decline in the Bcl-2 level was due to cleavage of the protein by c…
Differences in Kaposi sarcoma-associated herpesvirus-specific and herpesvirus-non-specific immune responses in classic Kaposi sarcoma cases and match…
2011
Kaposi sarcoma (KS) might develop because of incompetent immune responses, both non-specifically and specifically against the KS-associated herpesvirus (KSHV). Peripheral blood mononuclear cells from 15 classic (non-AIDS) KS cases, 13 KSHV seropositives (without KS) and 15 KSHV-seronegative controls were tested for interferon-γ T-cell (enzyme-linked immunospot [Elispot]) responses to KSHV-latency-associated nuclear antigen (LANA), KSHV-K8.1 and CMV/Epstein-Barr virus (EBV) peptide pools. The forearm and thigh of each participant was also tested for delayed-type hypersensitivity (DTH) against common recall antigens. Groups were compared with Fisher exact test and multinomial logistic regress…
La debolezza dei legami forti
2011
Ci sono forme di capitale sociale che promuovono lo sviluppo e altre che lo inibiscono. Durante il Medioevo, maghrebini e genovesi si contendevano il primato commerciale nell'area del Mediterraneo. A soccombere furono i maghrebini che godevano di una dotazione di capitale sociale comunitario, e cioè di affidabilità interna, maggiore dei genovesi. Proprio per questo non sentirono l'esigenza di sviluppare sistemi per rendere sicure le transazioni commerciali fra estranei.

Systemic acidemia impairs cardiac function in critically Ill patients.
2021
Background: Acidemia, is associated with reduced cardiac function in animals, but no studies showing an effect of acidemia on cardiac function in humans are reported. In the present study, we examined the effect of acidemia on cardiac function assessed with transpulmonary thermodilution technique with integrated pulse contour analysis (Pulse Contour Cardiac Output, PiCCO™) in a large cohort of critically ill patients. Methods: This was a prospective multicenter observational cross-sectional study of 297 patients from 6 intensive care units in London, England selected from all patients admitted consecutively between May 2018 and March 2019. Measurements of lowest plasma pH and concurrent ass…
The influence of business groups on board composition in offshore financial multinational enterprises
2023
Based on resource dependence theory we argue for an influence of business groups (BGs) on the board composition of constituent offshore financial multinational enterprises (FMNEs). Using a unique sample of 171 Caribbean FMNEs in an inter-island BG setting, we find BGs’ control in constituent firms to be indicative of the importance of the internal financing and intermediation within the group network. This control leads to a higher proportion of lawyers hired to the boards of directors in BG-constituent firms and supports the argument that lawyers provide skills in complex offshore regulatory frameworks that facilitate BGs’ optimal tax management. Furthermore, we observe that an increased a…
