Malignant vascular tumors are uncommon sarcomas that arise from endothelial cells of small blood vessels and may affect every organ. Pleural localization is very exceptional, and only 48 cases have been reported in the English literature to date. Even if etiological factors implicated in the development of vascular sarcomas are still unclear, the strongest(More)
bcl-6, CD10 and CD38 are useful markers for identifying 2 molecularly and prognostically distinct profiles of diffuse large B-cell lymphomas (LCLs), defined as germinal-center B-like and activated B-like. We investigated the prognostic role of bcl-6, CD10 and CD38 immunoreactivity in 102 gastrectomized patients with primary gastric lymphomas (PGLs). There(More)
Deletion of chromosome arm 6q is a frequent karyotypic alteration found in a variety of cancers and lymphoproliferative disorders, including leukemia and lymphomas. We characterized 6q deletions in 35 malignant lymphomas, using conventional and molecular cytogenetic approaches, to define the deletion pattern of 6q in different histological types.(More)
Cyclin D3 plays a pivotal role in controlling the physiological progression from the G1 to the S phase of the cell cycle. Recent data suggest that cyclin D3 may be deregulated in extranodal non-Hodgkin's lymphomas (NHLs) as a consequence of the t(6;14)(p21.1;q32.3) translocation. The present study investigated for the first time by dual-colour fluorescence(More)
We consider the Landau-Teller model, which is a prototype for the exchanges of energy, in molecular collisions, between internal degrees of freedom and those of the center of mass. We show that the statistics of the energy exchanges computed through the dynamics over a finite time is of the Lévy type for high enough frequencies of the internal motions,(More)
We study the thermodynamical properties of Fermi vapors confined in a harmonic external potential. In the case of the ideal Fermi gas, we compare exact density profiles with their semiclassical approximation in the conditions of recent experiments. Then, we consider the phase-separation of a multi-component Fermi vapor. In particular, we analyze the(More)
7531 Background: Hp infection plays a decisive role in the pathogenesis of low-grade gastric MALT lymphoma and eradication therapy has become a widely accepted initial treatment of stage I disease. The aim of this study was to evaluate the long term outcome of patients (pts) with localized gastric MALT lymphoma exclusively treated with Hp eradication(More)
Based on the histological criteria proposed by the REAL and adopted by the WHO Classification, 30 cases of MALT type lymphoma, 18 cases of diffuse large B cell lymphoma (DLCL), and 17 cases of DLCLs, associated with a MALT type, were identified in a series of 65 surgically treated primary gastric lymphomas. The clinical records of the patients were analyzed(More)
