Mantle Cell Lymphoma Case Report
Introduction: Due to the beginning of the use of immunophenotypic and cytogenetic techniques, new nosological forms of lymphoproliferative diseases have appeared over the past few decades. According to the WHO classification (2008), today there are more than 50 known lymphoproliferative diseases. Case Presentation: We present the case of a 51-year-old man with lymphoproliferative syndrome. Our patient underwent morphological and immunohistochemical investigations of biopsy materials from the right inguinal lymph node. The morphological picture was characteristic for small cell lymphoma. Immunophenotypically, tumor proliferate cells expressed CD20, CD76b, CD5, and cyclin D, and the tumor immunophenotype matched mantle cell lymphoma. Discussion: At the present stage of the development of medicine, the diagnosis of lymphoproliferative diseases is based on the clinical picture of the disease with the definition of localization and characteristics of the tumor process, morphological study of tumor tissue and cells, and immunophenotypic and/or cytogenetic analyses are mandatory to determine the final diagnosis
Eu2O3-HI-H2O and EuI3-HI-H2O Systems at 25°C
Phase equilibria in the Eu2O3-HI-H2O and EuI3-HI-H2O systems at 25°C are studied by the solubility method. The fields of crystallization of europium triiodide nonahydrate EuI3 · 9H2O and basic iodide Eu2I(OH)5 · 2H2O are established. The crystal hydrates are characterized by X-ray powder diffraction, thermogravimetry, and crystal optics

Cu, Mo-doped and pristine-BiVO4 thin films prepared by rf sputtering process for photocatalytic applications
International audienceCu, Mo-doped and pristine BiVO4 thin films were realized by coupling rf sputtering and mechanochemical synthesis technique. These monoclinic thin films were deposited over silicon substrate under the pure argon atmosphere (Ar 72 sccm). The sputtering targets were prepared by the respective ball-milled powders hydraulically pressed at optimal conditions. XRD analysis shows that the as-deposited thin films are amorphous and the monoclinic structure is obtained with a post-annealing process in the air at 450 °C for 2 h. Compositional, morphological and optical studies were thoroughly investigated by using FE-SEM, AFM and UV–Vis absorption spectroscopies respectively and discussed as a function of photocatalytic degradation of methyl orange organic dyes in solution. The pseudo first-order degradation rate constant values were estimated as 0.028, 0.031 and 0.022 min−1 for Cu, Mo-doped and pristine BiVO4 thin films respectively. Degradation performances are correlated as a function of their structural, surface morphological and film thickness aspects as well as the role of doping agent. Mo-doped high crystalline BiVO4 thin films with thickness 130 nm and morphology of small nano-sized islands on the surface (RMS = 5.08 nm) contributed well to the amplification of photocatalytic performance and followed by Cu doped and pristine BiVO4 thin films. © 2018, Springer Science+Business Media, LLC, part of Springer Nature
