    Notes: The previously observed phenomena of temporal and spatial self-organization during the catalytic oxidation of CO on a Pt(100) surface were computer simulated by use of the cellular automaton technique. The underlying model is footed on the knowledge about the individual reaction steps (adsorption, desorption, surface structural transformation, etc.), which in turn formed the basis of a previous theoretical treatment in terms of the formulation and solution of a set of coupled differential equations. The present result nicely show the formation and propagation of two-dimensional patterns, and they reproduce qualitatively well all the experimental observations. The development of macroscopic patterns even with an a priori perfectly homogeneous surface is a particularly interesting effect.

    Immunohistochemical localization of peanut lectin binding sites on human brain tumors as determined by peroxidase-antiperoxidase technique in paraffin sections (1983)

    Notes: Summary Peroxidase-antiperoxidase (PAP) technique was selected for visualizing the binding of peanut lectin (PNL) to the most frequent human brain tumors. The randomly selected material included neoplasms of neuroectodermal and mesenchymal origin. We employed 1–5 μm sections of routinely processed and paraffin-embedded tissues. PNL receptors were detected to a variable extent on the cell surface of astrocytoma, glioblastoma multiforme, oligodendroglioma, ependymoma, meningotheliomatous meningeoma, and plexus papilloma. In gliomas an increase in malignancy seems to be associated with a decrease in PNL binding. Except for the plexus papillomas, neuraminidase pretreatment had neither a qualitative nor a quantitative influence on the binding behavior of PNL. Intracellular PNL receptors could be detected in “granular cells” and in the perinuclear region of malignant gliomas.

    Geochemical proximity indicators of massive sulphide mineralization in the Iberian Pyrite Belt and the East Pontic metallotect (1983)

    Notes: Abstract A comparative lithogeochemical study of mainly surface rocks of the Iberian Pyrite Belt (volcanic-sedimentary sequence) and the East Pontic metallotect (volcanic island arc system with few intercalations of marine sediments) has been performed in order to find facies-independent proximity indicators of massive sulphide mineralizations. As, Sb, Tl, and Na seem to be the most promising indicator elements for primary hydrothermal exhalation and/or alteration haloes. The size of the alteration haloes largely depends on the permeability of the country rocks and is best defined by ratios such as As/Na, Sb/Na, and Tl/Na.

    Conspicuous enterocytic binding pattern for peanut lectin and malignant histiocytosis of the intestine (1983)

    Notes: Summary We present a case of a 33 year old male with a history of early childhood diarrhoea and more recently diagnosed gluten sensitive enteropathy, who died with active disease, ulcerative proctosigmoiditis and desquamative erythrodermia associated with toxin induced shock. Autopsy revealed a tumour restricted to lymph nodes of the mesentery and the retroperitoneum. This is considered to be malignant histiocytosis of the intestine (MIH). Immunohistological examination of the diagnostic jejunal biopsy showed a pathological binding pattern for peanut lectin (PNL) within the enterocytes. This may be an expression of disturbed production or secretion of a product rich in non-reducing terminal D-galactosyl residues.

    The distribution of fibronectin in lymph nodes infiltrated by Hodgkin's disease (1983)
    Springer

    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.

    Primary mediastinal clear cell lymphoma (1986)
    Springer

    ISSN: 1432-2307

    Topics: Medicine
    Notes: Summary This is a report on 8 mediastinal tumours that occurred in young adults (19–43 years, mean: 29.4); predominantly in females (6/8). Initial symptoms consisted of thoracic pain and venectasia and in only one case in B symptoms. After surgical tumour reduction, radiation and/or chemotherapy, local recurrence was observed in each case under clinical care; abdominal spread is presently suspected in 3 patients; 3 died 11, 13 and 22 months after diagnosis. None developed leukaemia. The tumours are B-cell neoplasms with a characteristic immunophenotype: leucocyte common antigen+, common acute lymphoblastic leukaemia antigen−, B 1-antigen+, surface and cytoplasmic immunoglobulin−. Flow cytometry revealed DNA-diploidy in 7 cases and a moderately (3.2–3.8%) to extremely high (8.0–20.6%) S-phase component. The proliferation associated antigen Ki67 was detectable in 10–60% of the tumour cell nuclei, thus stressing the considerable or rapid growth. Histopathology is characterized by a diffuse growth pattern and a clearness and abundance of cytoplasm of the pleomorphic tumour cells, which vary in size and nuclear morphology from patient to patient. Apoptoses are more numerous than mitoses. Fibrosis and focal necrosis are common, sclerosis is present in 3 cases. We suggest that primary mediastinal lymphoma of B cell type is a novel B-lymphoma variant.

    Differences in marker expression among branched histiocytic cells in T-cell areas of the lymphoreticular system and among their epidermis- and mucosa-associated equivalents (1986)

    Notes: Summary Branched histiocytic cells of the epidermis, the oral and anal mucosa, the tonsillar crypt epithelium, the thymus and of the T-cell-dependent areas of lymph node, spleen, and tonsil were examined with immunohistochemical single- and double-staining techniques. The markers used were a monoclonal anti-T6-antibody, a monoclonal anti-HLA-DR-antibody, heteroantiserum to S-100 protein and peanut agglutinin. Anti-HLA-DR and peanut agglutinin reacted with a considerable number of branched histiocytic cells, whereas anti-T6 and anti-S-100 protein only stained relatively small subpopulations. Concerning the population of branched histiocytic cells, double-staining revealed that the tissue distributions of all the markers used overlapped each other to various degrees; this was demonstrated by the different numbers of double-stained cells obtained in the experiments using all six possible combinations of primary reagents. The number of branched histiocytic cells co-expressing the markers varied depending upon marker combinations, types of tissue and microenvironment. We suggest that much of the immunologic phenotype of branched histiocytic cells is dynamic rather than static.

    On the stability of the transeinsteinium elements (1986)

    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.
