Endocrinological effects of high-dose Hypericum perforatum extract WS 5570 in healthy subjects
Get PDFIn this single-blind study, the effects of acute oral administration of high-dose Hypericum perforatum extract WS 5570 on the cortisol ( COR), adrenocorticotropic hormone ( ACTH), growth hormone (GH), and prolactin (PRL) secretions were examined in 12 healthy male volunteers. In a randomized order, the subjects received placebo or WS 5570 at several dosages (600, 900, and 1,200 mg) at 08.00 h on 4 different days. After insertion of an intravenous catheter, blood samples were drawn 1 h prior to administration of placebo or WS 5570 ( 600, 900, or 1,200 mg), at the time of administration, and during 5 h thereafter at intervals of 30 min. The serum concentrations of COR, GH, and PRL as well as the plasma levels of ACTH were determined in each blood sample by means of double antibody radioimmunoassay, fluoroimmunoassay, and chemiluminescence immunometric assay methods. The area under the curve value was used as parameter for COR, ACTH, GH, and PRL responses. Repeated-measures Anova revealed a significant stimulatory effect of WS 5570 on the ACTH secretion, whereas COR and PRL secretions were not significantly influenced. Moreover, there was a stimulatory peak of GH release 240 min after challenge with WS 5570 in some but not all volunteers, without reaching statistical significance in comparison with placebo. Mean arterial blood pressure and heart rate remained unchanged after administration of WS 5570. Apparently, WS 5570 at the dosages given in this study inconsistently causes endocrinological effects in healthy subjects by influencing central neurotransmitters. Copyright (C) 2004 S.

Efficacy of hypericum extract Ws<sup>®</sup> 5570 compared with paroxetine in patients with a moderate major depressive episode–a subgroup analysis
No full textIntroductionVarious studies showed the efficacy and tolerability of WS® 5570 (Hyperiplant® Rx, Dr. Willmar Schwabe GmbH & Co. KG) for the treatment of acute mild-to moderate depression. Beneficial effects of WS® 5570 have been also shown in patients with moderate-to-severe depression.Objectives/aimsWe present a subgroup analysis of a double blind, randomised trial to compare the therapeutic efficacy of WS® 5570 with paroxetine in patients suffering from a major depressive episode with moderate symptom intensity. This analysis on moderately depressed patients treated with WS® 5570 tries to support the hypothesis that WS® 5570 is an effective remedy in patients with major depression and moderate symptom intensity.MethodsModerate depression was defined by a baseline Hamilton Depression Rating Scale (HAM-D) total score between 22 and 25. Sixty-four patients received, after a single blind placebo run-in phase of 3–7 days, either 3 × 300 mg/day WS® 5570 or 20 mg/day paroxetine for six weeks. The change of the HAM-D total score was used to describe the efficacy of WS® 5570 compared with paroxetine in the subgroup of patients with moderate depression.ResultsThe reduction of the HAM-D total score was significantly more pronounced in patients treated with 3 × 300 mg/day WS® 5570 compared to 20 mg/day paroxetine. After six weeks, responder (87.1%) and remission rates (60.6%) to WS® 5570 were significantly higher than to paroxetine (71%/42.4%).ConclusionsAfter six weeks, patients treated with WS® 5570 showed a higher reduction in depression severity score and yielded greater response and remission rates compared with patients treated with paroxetine.Disclosure of interestSupported by Dr. Willmar Schwabe GmbH & Co.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
