Italian politics in an era of recession : the end of bipolarism?

Italian politics have undergone momentous change in the 2007–2017 decade under the impact of the eurozone crisis, whose peak in 2011–2013 could be equated to the earlier watershed years of 1992–1994. The lasting impact of the upheaval in Italian politics in the early 1990s could still be felt in the decade of economic recession, but there were also new challenges prompted by a crisis that had its roots in international financial contagion and which unravelled under the shadow of both recession and austerity. The changes were of an economic, social, cultural, institutional, policy-oriented and political nature. If one central quintessentially political theme stands out by the end of this decade it is the apparent exhaustion of the quest for bipolarisation that was initiated in the early 1990s

Nitinol Carbofilm coated stents for peripheral applications: Study in the porcine model

Purpose: Testing the safety and foreign body reaction (FBR) of a nitinol self-expandable carbon-coated stent system in the porcine animal model at different follow-up (FU) periods. Methods: Fifteen minipigs received 30 carbon-coated self-expandable nitinol stents in iliac arteries. Explants were carried out at 7 (3 animals), 30 (4 animals), 90 (4 animals) and 180 (4 animals) day FU, for evaluation of acute, sub-acute and chronic biological response to the implanted devices. Histological, immunohistochemical, histomorphometric and scanning electron microscopy (SEM) analyses were performed to assess inflammatory reaction, endothelialization process, neointimal growth and cellular composition. Results: Thirty stents were successfully implanted. No mural thrombi were observed at gross examination or by angiography. Histologically no significant inflammatory reaction was detected: the stents appeared covered by a thin monolayer of endothelial cells even at 7 day FU. The neointima presented homogeneous growth and moderate thickness after 30, 90 and 180 days explants (0.38± 0.36 mm, 0.33± 0.30 mm, 0.27± 0.25 mm respectively). Internal and external elastic laminae were intact in 95% of stented arteries. Histological data validations of vessel endothelialization was obtained with SEM for the seven day follow-up group. Conclusions: This study showed good remarkable technical performances, minimal FBR and biocompatibility comparable with other available pre-clinical experimentation

La misura del crown nella laminazione a caldo di semilavorati in lega di alluminio AA8011: misurazione e ottimizzazione

Il controllo della planarità dei laminati sottili in leghe di alluminio rappresenta una delle più importanti criticitàdi processo e influenza fortemente la qualità dei prodotti che, in larga parte, sono destinati al mercato dellatrasformazione ove sono sottoposti a processi di verniciatura, accoppiamento a polimeri, stampa litografica,tutte operazioni impossibili da realizzare su laminati non planari.Per ottenere laminati piani è fondamentale lavorare già a monte nella laminazione a caldo delle placche: lamisura del “crown”, ossia il profilo di spessore misurato sulla larghezza dei laminati a caldo e la sua forma,rappresenta un prerequisito fondamentale per ottenere successivi laminati a freddo piani.Preliminarmente al presente lavoro si è realizzata un’analisi causa-effetto del crown per capire quali sono iparametri che entrano in gioco durante la realizzazione di un profilo accurato (diagramma causa-effetto delcrown).Ci si è quindi concentrati sulla deformazione termica dei cilindri (bombatura termica) per cercare diottenere, su laminati a caldo, valori variabili del crown agendo sul raffreddamento dei cilindri di lavoro da partedel fluido lubro-refrigerante. Per verificare che i parametri esaminati avessero un effetto significativo sul crownè stata condotta un’analisi della varianza (ANOVA) a due vie con interazione.Come strumento di elaborazione statistica dei dati sono state utilizzate le superfici di risposta

Local representative democracy and protest politics:the case of the Five-star Movement

In recent years, protest politics has become a relevant phenomenon in various European countries. Italy has witnessed the rise of the Five-star Movement (M5S), an anti-establishment party, which, at the 2013 general election, obtained one-fourth of the total votes. However, the story of this ‘party-movement’ started at the local level, as a civic network aimed at changing administrative practices in municipal government. By using an original dataset on representation in 671 Italian municipalities from 2010 to 2014, this article aims to explain not only the subnational political success of the M5S but also the challenges and contradictions that a newly formed movement faces in multi-level electoral arenas

Head and neck region consolidation radiotherapy and prophylactic cranial irradiation with hippocampal avoidance delivered with helical tomotherapy after induction chemotherapy for non-sinonasal neuroendocrine carcinoma of the upper airways

Background: Non-sinonasal neuroendocrine carcinomas (NSNECs) of the head and neck are considered an unfrequent clinico-pathological entity. Combined modality treatment represents an established therapeutic option for undifferentiated forms where distant metastasis is a common pattern of failure.Methods: We report on a case of NSNEC treated with sequential chemo-radiation consisting of 6 cycles of cisplatin and etoposide followed by loco-regional radiation to the head and neck and simultaneous prophylactic cranial irradiation to prevent from intracranial spread, delivered with helical tomotherapy with the 'hippocampal avoidance' technique in order to reduce neuro-cognitive late effects.Results: One year after the end of the whole combined modality approach, the patient achieved complete remission, with no treatment-related sub-acute and late effects.Conclusions: The present report highlights the importance of multidisciplinary management for NSNECs of the head and neck, as the possibility to achieve substantial cure rates with mild side effects with modern radiotherapy techniques. © 2012 Franco et al; BioMed Central Ltd
