Motivi letterari nei libri per l’infanzia di Paolo Di Paolo
No full textThe article, organised in the form of a discussion, aims to analyse the themes and motifs of Paolo Di Paolo’s works that are addressed to young audiences. The author has recently published a large number of volumes directed just at younger readers. When beholding the titles that constitute the author’s bibliography, the reader is struck by Di Paolo’s predisposition to transform literary classics: as much in Giacomo il signor bambino as in the edition of the Divina Commedia, the author’s goal is to try to reach his new readers. Therefore, Di Paolo proves to be a prolific author of the genre; in fact, in his bibliography, volumes of fairy tales with a classic slant, such as La mucca volante, are listed as well.L’articolo contiene un’analisi di temi e di motivi delle opere di Paolo Di Paolo dirette al pubblico più piccolo. L’autore negli ultimi anni ha pubblicato un cospicuo numero di volumi indirizzati, infatti, proprio ai lettori più giovani. Ciò che stupisce scorgendo i titoli che costituiscono la bibliografia dell’autore, è la predisposizione a trasformare i classici della letteratura: tanto in Giacomo il signor bambino quanto nell’edizione della Divina Commedia l’obiettivo è cercare di raggiungere i lettori più giovani. Di Paolo si dimostra, quindi, un autore prolifico del genere, tant’è che nell’elenco non mancano volumi fiabeschi dal taglio classico come La mucca volante. Analizzare le opere giovanili dello scrittore costituisce un fatto inedito
Pier Paolo Pasolini e la società: il "sogno di una cosa" travolto dalla "nuova preistoria"
No full textL’articolo prende in esame – nel centenario della nascita – il “pensiero politico” di Pier Paolo Pasolini. Vengono pertanto scandagliati (soprattutto) i suoi scritti sulla società, ma frequenti sono le incursioni nella letteratura e soprattutto nel cinema di questo autore del tutto originale. Ne emerge lo spessore di concetti spesso usati dal poeta per analizzare e criticare il presente: Nuova Preistoria, nuovo capitalismo, consumismo, edonismo, il Potere, il Palazzo, il Processo, sviluppo e progresso, sacralità in primis. Si evidenzia inoltre come l’occhio e il giudizio di Pasolini siano stati principalmente guidati dalla passione e solo di rimando dalla ragione. Un ruolo non secondario nella sua percezione del reale ha inoltre assunto la sua omosessualità. Nella parte finale dello scritto si analizzano alcuni strumenti tecnici utilizzati dall’autore per svolgere la propria opera di comprensione del presente e della sua conseguente traduzione artistico-critica.The article examines - in the centenary of his birth - the "political thought" of Pier Paolo Pasolini.
Therefore, it scrutinizes (above all) his writings on society, but there are frequent incursions into the literature and especially into the cinema of this completely original author. What emerges is the depth of concepts often used by the poet to analyze and criticize the present: New Prehistory, new capitalism, consumerism, hedonism, Power, the Palace, the Process, development and progress, sacredness in primis. It also shows how Pasolini's eye and judgment were mainly guided by passion and only by reason. His homosexuality also played a significant role in his perception of reality. In the final part of the paper we analyze some technical tools used by the author to carry out his work of understanding the present and its consequent artistic-critical translation
CDX1 expression is reduced in colorectal carcinoma and is associated with promoter hypermethylation
No full textThe CDX1 homeobox gene encodes a transcription factor specifically expressed in normal intestinal and colonic epithelia, and CDX1 gene expression is affected during colorectal tumour progression. In this study, real-time quantitative RT-PCR was used to investigate CDX1 expression in 26 colorectal carcinomas. Reduced expression of CDX1 was observed in 19 of 26 colon carcinomas compared to matched normal colonic mucosa: the decrease in CDX1 expression ranged between 0.10 and 0.79 (21-90% decrease; mean 64.75% ±22; p = 0.001). Mutation and loss of heterozygosity (LOH) analyses were then used to determine if reduced CDX1 expression was due to genetic alteration. No CDX1 gene mutations, but two known polymorphisms in exon 1, were observed. LOH was observed in 33% of the tumours investigated but this was not related to CDX1 expression. Since aberrant promoter methylation is a well-known mechanism that participates in gene silencing, the methylation status of the CDX1 5′ CpG island promoter was also investigated. PCR amplification of bisulphite-treated DNA followed by cloning was performed in 7 carcinomas that showed low expression of CDX1 and in 1 colonic carcinoma without reduced expression. Promoter hypermethylation occurred in carcinomas in which CDX1 reduced expression was present. These results suggest that CDX1 promoter hypermethylation is one of the molecular mechanisms that accounts for reduced CDX1 gene expression in colorectal carcinoma.

Transitional Cell Carcinoma of the Retrorectal Space Arisen in Tailgut Cyst: A Case Report and Review of the Literature.
No full textTailgut cysts, also known as retrorectal cystic hamartomas, are congenital lesions derived by an abnormal remnant of the postanal primitive hindgut, consisting of unilocular or multilocular cysts usually lined by squamous, transitional, or glandular epithelium. Malignant transformation is an uncommon event, and it mainly involves the neuroendocrine or glandular epithelium; other histotypes are sporadic. Here, we report, for the first time, the clinicopathological features of a transitional cell carcinoma that arose in a tailgut cyst

Curative and prophylactic surgery of young-onset colorectal cancer in inherited syndromes. a 15-year monocentric retrospective experience
No full textBACKGROUND/AIM:
Although genoproteomic and clinicopathological knowledge on Lynch syndrome (LS) and familial adenomatous polyposis (FAP) has notably increased during the past two decades and even though surgery represents the mainstay of treatment for both conditions, as of 2019, the surgical choice in terms of timing and procedure still appears controversial in the absence of definitive guidelines.
MATERIALS AND METHODS:
Data were retrospectively analyzed of patients with colorectal cancer (CRC) surgically treated at our Institution between 1st January 2003 and 31st December 2018. Particular attention was given to patients with LS and FAP ≤45 years of age (young-onset CRC); for this category of patients, the surgical procedures performed were compared in terms of benefits and disadvantages.
RESULTS:
A total of 1,878 primary CRCs were submitted to major surgery; young-onset malignancies accounted for 3.8% of all CRCs. Thirteen young-onset inherited CRCs were surgically removed from 11 patients with LS and two with FAP. Segmental colectomy and restorative proctocolectomy were the procedures most frequently performed in young patients with LS and FAP, respectively.
CONCLUSION:
In the light of our retrospective results, we highlight the need for randomized controlled trials comparing the surgical options for LS- and FAP-related CRC developing in young patients. Defining the advantages and risks of each surgical option is of the utmost importance in order to improve prognosis of such patients and establish unanimous recommendations

Research summary: Termination of CHR
No full textConstraint Handling Rules (CHR) is a high-level programming language, designed for the easy implementation of custom constraint solvers. CHR is a language-extension, built on top of Java, C and half a dozen Prolog-variants. The language is currently used in many projects.
In contrast to earlier approaches, CHR has a ''no box''-approach and thus can implement any sort of solvers. Of course this affects the efficiency of the obtained solver. In order to obtain the same level of efficiency, we need analysis tools to detect the properties of a CHR program that lead to optimizations.
In CHR, termination is one of the most important properties of a program. Other important properties, such as confluence can be decided given termination. But also for the programmer this is an important property. CHR is a multi-headed language in which loops are often much more difficult to detect than in single-headed languages such as Prolog.sponsorship: This research is funded by the I.W.T.
