    Notes: Abstract Background: The translocation t(2;5)(p23;q35) leads to the fusion of thenucleophosmin gene (NPM) on chromosome 5q35 to the recently describedreceptor kinase ALK 2p23. It is characteristic of a subgroup of CD30+large-cell anaplastic non-Hodgkin's lymphoma (ALCL). Since some cases ofHodgkin's disease (HD) and ALCL share common features, a common pathogenesishas been proposed in a report of the expression of NPM/ALK fusion mRNA in11/13 Hodgkin's lymphomas. Patients and methods: We approached this question by micromanipulatoryisolation of single Hodgkin and Reed–Sternberg (H-RS) cells andsubsequent RT-PCR amplification of NPM/ALK fusion cDNA from these singlecells. Results: Specificity of cell selection was shown by the HD-specificpattern of EBV-gene expression in single H-RS cells. In 4 out of 7 cases,NPM/ALK fusion cDNA was detected in the RNA from whole lymph node tissue. In2 out of 9 cases, NPM/ALK fusion sequences were amplified from single H-RScells, albeit in a very low frequency (〈5%). Conclusions: These data indicate that NPM/ALK fusion transcripts donot play an early role in the pathogenesis of HD. Whether the rare expressionof NPM/ALK is the result of clonal heterogeneity or an indication for clonalevolution and progression toward ALCL can only be answered by the repeatedanalysis of indicator cases during the course of the disease.

    Cathepsin D and E co-expression in sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) and Langerhans' cell histiocytosis: further evidences of a phenotypic overlap between these histiocytic disorders (1994)

    Notes: Abstract Nosological classification of sinus histiocytosis with massive lymphadenopathy (SHML; Rosai-Dorfman disease) is difficult, and the normal cellular counterpart of Rosai-Dorfman (RD) cells is uncharacterised. The peculiar S-100+ phenotype of RD cells suggests a relationship with the dendritic cell family. Recent investigations have revealed cathepsin E to be selectively concentrated in antigen-presenting cells, whereas cathepsin D was found to be expressed in cells of macrophage lineage. Cathepsin D and E distribution was investigated by immunohistochemistry in a series of SHML biopsies and in two types of dendritic cell proliferative lesions: dermatopathic lymphadenitis (DL) and Langerhans' cell histiocytosis (LCH). In SHML biopsies, RD cells and monocyte-related elements of the sinuses and pulp coexpressed cathepsin D and E. LCH cells also stained for both these aspartic proteinases. Conversely, in DL cathepsin E and D were localised to separate cells that resembled Langerhans' cells (LC) or macrophages, respectively, in morphology and distribution. Our data outline the peculiar immunophenotype of RD and LCH cells and suggest that caution should be exercised in the identification of their normal cellular counterpart. The common expression of cathepsin D and E and of S-100 protein suggests some phenotypic overlap between SHML and LCH cells, despite their striking morphological divergence.

    The distribution of fibronectin in lymph nodes infiltrated by Hodgkin's disease (1983)
    Springer
    Virchows Archiv 400 (1983), S. 319-329 
    Details
    ISSN: 1432-2307
    Keywords: Hodgkin's disease ; Fibronectin ; Fibroblast ; Immunoperoxidase study

    Topics: Medicine
    Notes: Summary The tissue distribution of fibronectin (FN) was examined using a commercial anti-FN serum, the peroxidase-anti-peroxidase (PaP) technique, and paraffin sections of 22 lymph nodes affected by Hodgkin's disease. Vascular basement membranes and reticulin fibres are selectively stained and their structural changes in this pathological condition become readily visible. In contrast to the normal lymph node and to Hodgkin's disease with lymphocytic predominance, cases of mixed cellularity disease contain individual and focally grouped cells displaying intracytoplasmic FN. In nodular sclerosis these cells with fibroblast morphology are consistently numerous in the marginal zones of the cellular nodes. Strongly reacting mastocytes probably absorbed the applied anti-serum non-immunologically. All the other cell types giving rise to the varying appearances of Hodgkin's lesions are consistently negative with respect to intracellular FN, including all forms of Hodgkin cells. We conclude that in Hodgkin's disease the immigration of FN-secreting fibroblasts is an integral part of the early sclerosing reaction, which in itself is a defence/repair mechanism closely related to scar formation.

    On the stability of the transeinsteinium elements (1986)
    Springer
    The European physical journal 323 (1986), S. 41-45

    ISSN: 1434-601X

    Notes: Abstract We calculate ground-state properties of nuclei in the Z≧100 region. The most stable superheavy elements are predicted for lower neutron number than in previous investigations, namely 110 288 X and 110 290 X, both with a calculated half-life of around 200 days. A new feature is a local minimum in the ground-state shell correction at Z=110 andN=162. Elements in this region are therefore expected to show increased stability relative to some earlier expectations.
