Two cases of diffuse dermal angiomatosis are reported in middle-aged women. This rare disease of unknown origin is characterized by increased dermal angiomatosis and ulceration. The clinical and histologic presentations of the presently reported lesions were typical for this disorder. Endothelial cells exhibited a normal immunophenotype. The perivascular basement membranes showed a distribution of collagen alpha chains typical for blood vessels, but not for lymphatics. Immunohistochemistry revealed other undescribed features. At the site of the clinical lesions, linear and granular deposits of immunoglobulins A and M, and complement were found around the vessels and at the dermal-epidermal junction. The same deposits were also found restricted to the dermal-epidermal junction in the peripheral clinically intact skin. No serological signs of auto-immune disorder were detected in one patient. A monoclonal gammopathy was disclosed in the other patient. A pattern of immunoreactant deposits similar to that disclosed in the two patients was not found in the control specimens, and has not been described so far in other types of vascular hyperplasia and neoplasia. A pathogenic role of these deposits is unsettled and should be further explored. [less ▲]

Background Diffuse large B-cell lymphomas (DLBCLs) arising in specific extranodal sites have peculiar clinicopathologic features. Patients and methods We analyzed a cohort of 187 primary Waldeyer's ring (WR) DLBCLs retrieved from GELA protocols using anthracyclin-based polychemotherapy. Results Most patients (92%) had stage I–II disease. A germinal center B-cell-like (GCB) immunophenotype was observed in 61%, and BCL2 expression in 55%, of WR DLBCLs. BCL2, BCL6, IRF4 and MYC breakpoints were observed in, respectively, 3 of 42 (7%), 9 of 36 (25%), 2 of 26 (8%) and 4 of 40 (10%) contributive cases. A variable follicular pattern was evidenced in 30 of 68 (44%) large biopsy specimens. The 5-year progression-free survival (PFS) and the overall survival (OS) of 153 WR DLBCL patients with survival information were 69.5% and 77.8%, respectively. The GCB immunophenotype correlated with a better OS (P = 0.0015), while BCL2 expression predicted a worse OS (P = 0.037), an effect overcome by the GCB/non-GCB classification. Compared with matched nodal DLBCLs, WR DLBCLs with no age-adjusted international prognostic index factor disclosed a better 5-year PFS rate (77.5% versus 70.7%; P = 0.03). Conclusions WR DLBCLs display distinct clinicopathologic features compared with conventional DLBCLs, with usual localized-stage disease, common follicular features and a high frequency of GCB immunophenotype contrasting with a low rate of BCL2 rearrangements. In addition, they seem to be associated with a better outcome than their nodal counterpart. [less ▲]

Le commerce et les biens culturels sont une source perpétuelle d’antagonisme et de désaccords tant au niveau national qu’international. La culture est un champ d’intérêt commercial considérable ainsi qu’une expression profondément significative du patrimoine national et du dynamisme artistique. D’ailleurs, la culture est inéluctablement vouée à osciller entre la sphère artistique et la sphère marchande. La nature ambiguë et équivoque des activités et des expressions culturelles - et en particulier audiovisuelles - suspendues entre l’art et l’industrie, entre la production symbolique et la production matérielle, suscite de plus en plus un débat politique à la fois virulent et polémique sur la scène internationale. La question de la préservation de la diversité des expressions culturelles et la nécessité de la protection « des écosystèmes culturels » dans le contexte de globalisation croissante économique et financière a pris depuis une quinzaine d’années une ampleur, difficilement imaginée auparavant. En effet, la problématique de base qui est soulevée est celle de la circulation des produits culturels à l’échelle mondiale, régionale, ainsi que nationale et celle du traitement à accorder aux biens/services culturels et artistiques dans les accords commerciaux internationaux.

In this work we investigate the diffusion of Ag dimer on Cu(110) surface by molecular dynamics simulation based on semi-empirical many-body potentials derived from the embedded atom method. The dissociation-reassociation process is predicted to be dominant in static regime and this is confirmed by the dynamic investigation. A good agreement is found between static activation barrier and dynamic potential barrier. © 2012 IEEE. [less ▲]
