The ectomycorrhizal community of Abies nebrodensis: preliminary results
Abies nebrodensis (Lojac.) Mattei is a Critically Endangered forest tree included in Appendix I of the Bern Convention and as a priority species in Annexes II and IV of the Habitats Directive [1]. In situ and ex situ conservation strategies [2] and, more recently, a LIFE Natura project [3] allowed a marked improvement of health conditions of trees and of seedlings renewal. A first attempt to characterize the ectomycorrhizas of A. nebrodensis was carried out by Venturella & Rambelli [4]. In the frame of the activities of the II National Workshop of Ectomycorrhyza (Palermo, 2015), this paper reports the preliminary investigation carried out on the ectomycorrhyzal community of A. nebrodensis i…
Educazione e recalcitranza. Brevi note sulla nozione di paideia in Aristotele
Leonardo Samonà dedica delle interessanti riflessioni al concetto di paideia nel libro Gamma e proprio prendendo spunto da tali riflessioni, pur da una prospettiva diversa e con intenti teorici differenti, il saggio si concentra su questo peculiare uso di paideia che si ritrova nei testi aristotelici, con particolare attenzione alle sue implicazioni in Metafisica Gamma. Un uso che ha a che fare con la questione dei principi primi, con il tema dell'adeguatezza epistemologica e con la relazione conflittuale e problematica con la figura del recalcitrante.
Transcatheter arterial chemoembolization for hepatocellular carcinoma in cirrhosis;survival rate and prognostic factors
Background: The role of prognostic variables in the treatment of hepatocellular carcinoma (HCC) by transarterial chemoembolisation (TACE) is controversial. Aims: To evaluate the survival of patients with HCC on cirrhosis treated with TACE and to analyse the prognostic factors affecting survival. Methods: From 1996 to 2006, 580 consecutive patients with HCC in cirrhosis were observed. Of these 194 patients underwent TACE. The primary end-point was survival. Independent predictors of survival were identified using the Cox model. Results: The cumulative 1-year, 3-year, and 5-year survival rates were 96%, 60%, and 41%, respectively. The multivariate analysis showed significant reduction of surv…
