IL CARCINOMA EPATOCELLULARE NEL FEGATO CIRROTICO. ANALISI IMMUNOISTOCHIMICA E MORFOMETRICA
HEPATOCELLULAR CARCINOMA IN THE CIRRHOTIC LIVER. IMMUNOHISTOCHEMICAL AND MORPHOMETRIC ANALYSIS.
Objective: To explore how morphometry can minimize subjectivity in the assessment of liver nodules in cirrhosis using a novel classification tool.
Study design: 8 hepatocellular carcinomas (HCC), 5 high-grade dysplastic nodules (HGDN), 8 large regenerative nodules (LRN), and 18 regenerative (cirrhotic) nodules (CN) obtained from cirrhotic explant livers, were analyzed using a Kontron-Zeiss KS400 image analyzer. We generated a morphometric model based on the analysis of volume fractions occupied by hepatocyte nuclei/cytoplasm, sinusoidal endothelium and lumen, neoplastic acini, fibrosis, centrilobular veins, portal arteries, veins and bile ducts, individual lesional arteries (smooth muscle actin), capillarized sinusoids (CD34), new vessels (CD31) and on surface fraction occupied by reticulin, and number in unit volume and size distribution of hepatocyte nuclei, and mean hepatocyte nucleus diameter and volume.
Results: Volume fraction of capillarized sinusoids, new vessels and individual lesional arteries were more prominent in HCC and HGDN, when compared with LRN and CN, whereas surface fraction of reticulin was markedly decreased in HCC. The morphometric values of these three features were integrated into our classification tool to construct a hybrid system, which reclassified the nodules in the same categories.
Conclusions: Our novel hybrid classification tool may minimize subjectivity in the histological assessment of nodular lesions in cirrhosis

Proporzioni numeriche nelle prospettive di Francesco del Cossa
Questo contributo propone un ampliamento delle indagini sulle architetture dipinte dipinte dal pittore ferrarese Francesco del Cossa tra il 1469 e il 1472: si tratta delle architetture dei mesi di Marzo ed Aprile del Salone dei Mesi di Schifanoia (Ferrara, 1469-70) e della pala dell’Annunciazione dell’Osservanza oggi conservata a Dresda (inedito). L’obiettivo è quello di indagare sull’esistenza di regole geometriche e costruttive eventualmente utilizzate per la definizione grafica degli spazi architettonici dipinti. Sono analizzati gli elementi geometrici della prospettiva, viene proposta una restituzione dell’alzato in vera forma e ipotizzata una metodologia di tracciamento delle profondità attraverso criteri geometrici e proporzionali in relazione al trattato di Piero della Francesca
FRANCESCO FERRARA E LUIGI COSSA: OVVERO L’ANTISOCIALISMO PRIMA DEL MARGINALISMO
Il saggio analizza l'antisocialismo come elemento comune del pensiero di due economisti del Risorgimento, Francesco Ferrara e Luigi Cossa, diversi sotto ogni altro punto di vista, teorico e non
DISCOVERING THE EVERYDAY LANDSCAPE A cultural heritage education project in the urban periphery
Heritage and landscape education is crucial to training
young people in active and responsible citizenship,
protection of the public assets, appreciation of the
cultural diversity and intergenerational dialogue.
Therefore, it cannot be limited to sporadic experiences
and on outstanding heritage and contexts but must be
transdisciplinary, inclusive and practicable everywhere.
This book relates the research and action project
“Scuola Attiva Risorse” (ScAR), winner of the Polisocial
Award that recognizes research for social purposes
at the Politecnico di Milano. The text describes an
experimental and innovative action delivered within
the fragile context of the urban peripheries. This
participatory process involved schools, universities,
cultural institutions, administrations and private actors
in interpreting and enhancing the “hidden” cultural
heritage in Milan’s fringe neighbourhoods
Comparison between PSB and VVER-1000 steam generator modeling
This paper presents a comparison between the dynamic performance of PSB and VVER 1000 steam
generator models.
PSB is a large-scale integral test facility which simulates the VVER-1000/320 reactor. Volume and
power scale are 1:300. It has four loops and each SG consists of 34 helicoidally tubes connected by two
headers named hot and cold collector respectively.
The Relap 5 nodalisation for the VVER 1000 was developed and qualified at DIMNP of University
of Pisa, refs. /1/ and /4/, and the secondary side performance was investigated in detail.
The goal of the paper is to analyse similarities and differences in the thermal hydraulic behaviour of
the reference steam generator and of the model. The same philosophy has been pursued in nodalising the two
systems
