Oligophrenin-1 regulates synaptic activity dependent shuttling between synapses and nucleus of Rev-erbAalpha
No full textThe GLUR2 subunit of AMPA receptors : synaptic role
No full textAmpa receptors mediate the majority of excitatory synaptic transmission in the brain. Thus, the mechanisms that control the developmental and activity-dependent changes in the functional synaptic expression of AMPA receptors are of fundamental importance. Here we focus on the role of GluR2 subunit in synaptic function and plasticity. (C) 2009 IBRO. Published by Elsevier Ltd. All rights reserved

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
Reabsorption of a saline or plasma induced hydrothorax
No full text In supine rabbits injection of 2 ml of saline into the lower right diaphragmatic region increased pleural liquid pressure at the injection point and, to a minor extent, on the costal and mediastinal side, indicating a redistribution of liquid among the pleural compartments. Over a period of 120 min end-expiratory liquid pressure on the diaphragmatic and costal surfaces approached the control value as a result of local reabsorption. No difference in the time course of liquid pressure was found on injection of either saline or homologous plasma. This was confirmed by measuring the volume of saline or plasma remaining in the cavity 90 min after injection; the net absorption flow amounted to 0.22 ml . kg-1 . h-1. These results suggest that local absorption mechanisms are relatively independent of the Starling pressure gradients acting across the pulmonary-perfused (-10.2 and 6.6 cmH2O with saline and plasma, respectively, the negative sign indicating a reabsorption gradient) and systemically perfused mesothelium (3.3 and 20.1 cmH2O with saline and plasma, respectively). </jats:p
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
