Mutations in the cardiac desmosomal protein desmoglein-2 (DSG2) are associated with arrhythmogenic right ventricular cardiomyopathy (ARVC). We studied the explanted heart of a proband carrying the DSG2-N266S mutation as well as transgenic mice (Tg-NS) with cardiac overexpression of the mouse equivalent of this mutation, N271S-dsg2, with the aim of(More)
BACKGROUND Apoptosis has recently been proposed to contribute to the pathogenesis of emphysema. METHODS In order to establish if cell fate plays a role even in end-stage disease we studied 16 lungs (9 smoking-associated and 7 alpha1antitrypsin (AAT)-deficiency emphysema) from patients who had undergone lung transplantations. Six unused donor lungs served(More)
Epstein-Barr virus-associated gastric carcinoma (EBVaGC) is a unique type of gastric cancer, defined as the presence of EBV in gastric tumour cells, usually identified by in situ hybridization. A poorly differentiated gastric adenocarcinoma was detected in a kidney recipient 33 years after transplantation. Neoplastic epithelial cells were EBV positive by in(More)
Pathogenetic mechanisms of hepatocellular carcinoma (HCC) are still unclear and new tools for diagnostic and therapeutic purposes are ongoing. We have assessed whether squamous cell carcinoma antigen (SCCA), a serpin overexpressed in neoplastic cells of epithelial origin, is also expressed in liver cancer. Squamous cell carcinoma antigen was evaluated by(More)
The accumulation of T cells in the synovial membrane is the crucial step in the pathophysiology of the inflammatory processes characterizing juvenile idiopathic arthritis (JIA). In this study, we evaluated the expression and the pathogenetic role in oligoarticular JIA of a CXC chemokine involved in the directional migration of activated T cells, i.e.(More)
Arachnoid cysts are frequent incidental findings on neuroimaging studies and in clinical practice. Theories of their origin, still matter for debate, compose four categories: 1) a ball-valve mechanism; 2) an osmotic gradient between the intra- and extracystic medium; 3) primary malformation of the arachnoid membrane or cerebral lobe agenesis; and 4) fluid(More)
Amplicon-based targeted resequencing is a commonly adopted solution for next-generation sequencing applications focused on specific genomic regions. The reliability of such approaches rests on the high specificity and deep coverage, although sequencing artifacts attributable to PCR-like amplification can be encountered. Between these artifacts, allele(More)
UNLABELLED Glomerular protein handling mechanisms have received much attention in studies of nephrotic syndrome. Histopathological findings in renal biopsies from severely proteinuric patients support the likelihood of protein endocytosis by podocytes. ClC-5 is involved in the endocytosis of albumin in the proximal tubule. AIM To investigate whether ClC-5(More)
Aim of our study was to evaluate SMCs changes in the media and neointima of the vessel wall at different time intervals after balloon injury in a rabbit animal model of intimal hy-perplasia, with special reference to the relation between apoptotic cell death and SMC hy-perplasia. Forty male New Zealand White rabbits were used for this study. Wall injury was(More)
Peripheral Ameloblastoma (PA) is the rarest variant of ameloblastoma. It differs from the other subtypes of ameloblastoma in its localization: it arises in the soft tissues of the oral cavity coating the tooth bearing bones. Generally, it manifests nonaggressive behavior and it can be treated with complete removal by local conservative excision. In this(More)
