Comparative Cytogenetics Allows the Reconstruction of Human Chromosome History: The Case of Human Chromosome 13

2019

Comparative cytogenetics permits the identification of human chromosomal homologies and rearrangements between species, allowing the reconstruction of the history of each human chromosome. The aim of this work is to review evolutionary aspects regarding human chromosome 13. Classic and molecular cytogenetics using comparative banding, chromosome painting, and bacterial artificial chromosome (BAC) mapping can help us formulate hypotheses about chromosome ancestral forms; more recently, sequence data have been integrated as well. Although it has been previously shown to be conserved when compared to the ancestral primate chromosome, it shows a degree of rearrangements in some primate taxa; fu…

TP53 mutations and S-phase fraction but not DNA-ploidy are independent prognostic indicators in laryngeal squamous cell carcinoma

2005

ToprospectivelyevaluatetheprognosticsignificanceofTP53,H-,K-,andN-Rasmutations,DNA-ploidyandS-phasefraction(SPF) in patients affected by locally advanced laryngeal squamous cell carcinoma (LSCC). Eight-one patients (median follow-up was 71 months) who underwent resective surgery for primary operable locally advanced LSCC were analyzed. Tumor DNA was screened for mutational analysis by PCR/SSCP and sequencing. DNA-ploidy and SPF were performed byflow cytometric analyses. Thirty-six patients (44%) had, at least, a mutation in the TP53 gene. Of them, 22% (8/36) had double mutations and 3% (1/36) had triplemutations.Intotal,46TP53mutationswereobserved.Themajority(41%)oftheseoccurinexon5(19/46),…

Treatment of esophageal cancer in inoperable elderly patients: our experience

2009

The esophagus carcinoma has an incidence rate of 3–4 new cases per 100,000 inhabitants, per year, with a male/female ratio of 3:1 and with a low incidence between the VI–VII decade of life. In Italy, the incidence rate equals 2,000 new cases/year with a mortality rate of 3–5/100,000 inhabitants.

Contributo alla conoscenza della vegetazione forestale dell’Egeo.

2004

Nell'ambito di ricerche fitosociologiche nell'area egea vengono presentati i risultati relativi alle formazioni forestali attualmente osservabili nelle isole dell'Egeo meridionale. Questo tipo di vegetazione è stato in precedenza oggetto di studio da parte di vari autori, fra cui in particolare Krause et al. (1963), Zohary & Orshan (1966), Barbero & Quezel (1980), Costa et al. (1984) e Géhu et al. (1989, 1990, 1992), che hanno esaminato sotto il profilo fitosociologico alcune isole dell'Egeo quali Eubea, Creta, Rodi e Karpatos. Allo scopo di ampliare le conoscenze su quest'area del Mediterraneo, ancora poco nota dal punto di vista vegetazionale, sono state effettuate indagini su numerose is…

Zur therapie der �sophagusvarizenblutung in der Bundesrepublik Deutschland (West) ? Ergebnisse einer Urnfrage

1991

An 1076 chirurgischen und internistischen Abteilung in der BRD (West) wurde eine Umfrage zur Behandlung der Osophagusvarizenblutung durchgefuhrt. Es uberwiegt die Akutsklerosierung bzw. die Ballonsondenbehandlung mit nachfolgender Sklerosierung bei der aktiven Blutung. Die abdominelle Sperroperation wird bei der konservativ nicht stillbaren Blutung noch vor dem portokavalen Notshunt bevorzugt. Betablocker werden vor allem in internistischen Abteilungen zur Rezidivprophylaxe eingesetzt. Erst nach mehrfacher Rezidivblutung trotz Sklerosierung sehen etwa die Halfte der Abteilungen eine Indikation zum elektiven Shunt. Der distale splenorenale Shunt nach Warren and die portokavale Anastomose dom…

A generic TG-186 shielded applicator for commissioning model-based dose calculation algorithms for high-dose-rate Ir-192 brachytherapy

2017

PurposeA joint working group was created by the American Association of Physicists in Medicine (AAPM), the European Society for Radiotherapy and Oncology (ESTRO), and the Australasian Brachytherapy Group (ABG) with the charge, among others, to develop a set of well-defined test case plans and perform calculations and comparisons with model-based dose calculation algorithms (MBDCAs). Its main goal is to facilitate a smooth transition from the AAPM Task Group No. 43 (TG-43) dose calculation formalism, widely being used in clinical practice for brachytherapy, to the one proposed by Task Group No. 186 (TG-186) for MBDCAs. To do so, in this work a hypothetical, generic high-dose rate (HDR) Ir-19…

The role of the innate immune response in HPV-related oral and oropharyngeal cancer

2014

Introduction. During the last 20 years, the incidence of HPV-associated oropharyngeal cancer is increased. Principal actors of the innate immune response against HPV are represented by the TLRs (Toll like receptors). On the other hand different studies have reported that HPV can directly inhibit the functions of the TLRs pathway through interferons (IFNs). There are very few preliminary studies on the role of TLRs mediated HPV clearance in human oncology. Our study aim has been to evaluate whether TLR4 identifies HR-HPV integration state in OSCC. Methods. Protein levels of TLR4 in OSCC were assessed using Immunohistochemistry (IHC). In situ hybridization (ISH) for HPV-DNA detection in morph…
