Lymphoproliferative disorder of large granular lymphocytes: reversal of lymphocyte proliferation, anemia and neutropenia with chlorambucil
No full textA 54-year-old woman presented with hepatosplenomegaly, anemia, neutropenia and lymphocytosis. Most peripheral blood lymphocytes had the surface antigens T3+, Leu11+ and were morphologically large granular lymphocytes. Bone marrow presented 60% lymphoid infiltration. Treatment with chlorambucil produced complete reversal of hepatosplenomegaly, anemia, neutropenia and lymphocytosis, and reduction of marrow infiltration. The patient is well 12 months after discontinuation of therapy

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Granulocyte colony-stimulating factor (G-CSF) prevents dose-limiting neutropenia in lymphoma patients receiving standard dose chemotherapy.
No full textEffects of recombinant human H-subunit and L-subunit ferritins on in vitro growth of human granulocyte-monocyte progenitors.
No full textWe have studied the influence of purified recombinant human H-subunit (rHF, acidic) and L-subunit (rLF, basic) ferritins on in vitro colony formation by normal human granulocyte-macrophage progenitor cells (CFU-GM). Whereas rLF had no significant effect, rHF produced significant decrease in colony formation: mean inhibition of CFU-GM was 38% +/- 13% at 10(-8) M and 22% +/- 13% at 10(-9) M. The inhibitory activity of rHF was lost at 10(-10) M, and was inactivated with a monoclonal antibody recognizing the H subunit, but not with a monoclonal antibody recognizing the L subunit. Although H-type isoferritins were found in normal and leukaemic cells, their concentration in peripheral blood plasma and bone marrow plasma from normal subjects and patients with different haematological disorders including acute leukaemia were 10(-11) M or lower, i.e. levels showing no activity in vitro. We conclude that: (i) acidic H-subunit-rich isoferritins have inhibitory effects on in vitro growth of granulocyte-macrophage progenitors; (ii) levels of these isoferritins in peripheral blood and bone marrow plasma are 2-3 orders of magnitude lower than the effective concentrations in vitro, indicating that these molecules do not behave as circulating regulatory or suppressive factors in vivo
