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)
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)
OBJECTIVE Anticalcification strategies of glutaraldehyde-fixed xenograft tissue aim to extract lipids or to neutralize toxic aldehyde residuals. The purpose of this study was to evaluate the efficacy of octanediol compared to standard treatments of glutaraldehyde-fixed bovine pericardium in the subdermal rat model. Octanediol treatment is an ethanolic(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)
