Expression profiles of miR-202-5p and miR-202-3p in adult tissues and during embryonic development.
No full text(A) Sequence and hairpin secondary structure of pre-mir-202. MiR-202-5p is in red and miR-202-3p is in blue. (B, C) Tissue distribution of miR-202-5p and miR-202-3p in eleven adult tissues obtained by TaqMan qRT-PCR (Box plots, n = 8, the ends of the boxes define the 25th and 75th percentiles; a line indicates the median and bars define the 5th and 95th percentiles). Cel-miR-39-3p was used as an external calibrator for normalization. (D, E) Expression profiles of miR-202-5p and miR-202-3p during embryonic development obtained by TaqMan qRT-PCR. Pools of embryos at the same stage were used. (F, I) Expression profiles of miR-202-5p and miR-202-3p in adult tissues and during embryonic development obtained by small RNA-Seq. ns, no significant difference (Student t-test, p > 0.05). #, expression levels not significantly different from the background signal.</p
Expression of miR-202-5p and miR-202-3p in the ovary.
No full textFluorescent in situ hybridizations (FISH) were performed on sections of ovaries from juvenile and adult medaka females. MiR-202-5p (A, B) and miR-202-3p (C, D) were detected with specific LNA miRNAs detection probes (in red). Ovaries of adult females were dissected from the transgenic medaka line Tg(sox9b::EGFP). The somatic GFP+ cells of the germinal cradle, including early granulosa cells, were immunodetected (in green) (B, D). Nuclei are stained with DAPI (in blue). (A’) A magnified view of the juvenile ovarian section. (B’, B” and B”’) Magnified views of the adult ovarian section. Mir-202-5p is detected in granulosa cells of follicles at all stages in both juvenile and adult ovary (arrowhead), but not in the theca cells (arrow). (B”’) MiR-202-5p co-localize with GFP in early granulosa cells surrounding pre-vitellogenic follicles. (C, D) Mir-202-3p is not detected in ovaries from juvenile and adult fishes. PreV, pre-vitellogenic follicle; V, vitellogenic follicle; PV, post-vitellogenic follicles. Scale bars: 500 μm (A-D), 50 μm (A’, B’, B”) and 20 μm (B”’).</p
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
