No full textLow dose interleukin-2 and 13-cis-retinoic acid as maintenance therapy in patients with solid tumors responsive to chemotherapy
No full textAfter aggressive surgery and chemotherapy, patients (PTS) with advanced solid tumors have often an impaired immune function that may facilitate tumor relapse. We have demonstrated, in a phase IB study, that administering low-dose interleukin-2 (IL-2) and 13-cis retinoic acid (RA), there was a significant improvement of the immune function, with low toxicity, in PTS with advanced tumors that had been treated with aggressive surgery and chemotherapy (Clin Cancer Res 7: 1251-1257, 200 1). A further A phase 11 study (International J Oncology 20: 1275-82, 2002) showed the efficacy of IL-2/RA in improving immunological parameters and in prolonging response in the same category of PTS. Aim of this study was evaluate the clinical and laboratory outcome of 214 patients, with advanced solid tumors, that, after aggressive surgery and chemotherapy, were treated with: subcutaneous IL-2 1.8 x 10(6) IU and oral RA, 0.5 mg/Kg for 5 days/week for 2 cycles of 3 weeks, with a 1-week rest, for up to 2 years. After a median follow-up time of 31 months, there was a statistically significant improvement in the number of lymphocytes, T4/T8 ratio, NK, with respect to baseline values. Responses were maintained for a median time of 36.4 months, while median survival was not reached yet (57% of PTS alive). These data show that the administration of low-dose IL-2/RA determines, with a low toxicity, a sustained increase in the immunological parameters known to be prognostically relevant
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
LIFETIME MEASUREMENTS FOR 46Ti AND 50Cr USING THE AGATA SPECTROMETER
Full text linkLifetimes of nuclear-excited states of the cross-conjugate pair of nuclei 46Ti and 50Cr were measured by using the Doppler Shift Attenuation Method (DSAM). High-spin states of these two nuclei were populated by a fusion–evaporation reaction, 16O(36Ar, αn). The reduced transition probabilities obtained from the experimental lifetimes are discussed in the framework of theoretical calculations obtained from the shell model using the KB3G and GXPF interaction. Rotational collectivity decreasing by the termination of the yrast band has been confirmed in both nuclei
