Optical properties investigation and multicolor behavior of neodymium (Nd)-doped oxyfluoride silicate glasses SiO-PbO-PbF.

The aim of this research is to investigate novel compositions of oxyfluoride glasses doped with Neodymium (Nd) rare earth ions in the visible spectrum. This area has not been extensively studied in the existing literature, so it is vital to understand the favorable photoluminescence characteristics within this part of the electromagnetic spectrum. Therefore, we synthesized and characterized SiO-PbO-PbF (SPF) doped with 1% neodymium (Nd) ions glasses.

Aberrant expression of CD5 in a case of B acute lymphoblastic leukemia positive Philadelphia chromosome.

Introduction: B acute lymphoblastic leukaemia (B-ALL) is a proliferation of hematopoietic precursor cells characterized by the expression of various B-cell antigens. Expression of T cell antigens has rarely been reported in B-ALL. We report the second case CD5+ (Cluster of differentiation 5) B-ALL associated with Philadelphia chromosome (Phi+).

Blastic plasmacytoid dendritic cell neoplasm: a diagnosis not to be missed, about three case reports.

Introduction: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a proliferation of plasmacytoid cell precursors. It is a rare and difficult-to-diagnose hematological malignancy with a poor outcome.

Case Presentation: We report three cases of BPDCN diagnosed in patients of different nationalities (Tunisian, Algerian and Libyan) and varying ages (eight, 65 and 74 years old).

[Primary plasma cell leukemia: what role does flow cytometry play?].

Primary plasma leukemia is defined by the presence of more than 20% plasma cells in the peripheral blood or number of circulating plasma cells greater than 2G/L. It has points in common with multiple myeloma and has certain characteristics, in particular its aggressiveness and poor prognosis. Through 02 cases diagnosed in the flow cytometry laboratory, the authors present the clinical, cytological and especially immunophenotypic features of this disease, with the emphasis on the role of flow cytometry in the diagnosis.
