Chromatin looping links gene expression to the assembly of transcription factories (Review)
No full text: Genes are not randomly dispersed within the nuclear space, instead they occupy precise sites either with respect to the nuclear lamina as well as to each other. This observation stands at the basis of the today well accepted concept of nuclear territories where any chromosome shows reproducible spatial connections with a selection of others in a general picture that meets a functional criterion where genes that answer the same stimuli are grouped in the same sites. In fact, transcription is not visible widely dispersed throughout the nucleus but is gathered in several 'granules', called transcription factories that accommodates ~10 genes concurrently transcribed. This dynamic behavior of chromosomes is allowed by changes in chromatin plasticity that are governed by several classes of proteins that either modify its building or induce post‐translational modifications in the protein component of nucleosomes, triggering formation of chromosome loops that modify the location of specific sites along the DNA strand. For example, transcription associated to nuclear receptors benefits of the generation of nuclear ROS that induce nicks following activation of the DNA repair apparatus that enhance helix unfolding and chromosome bridging. In the present review, the role that protocols facing elucidation of chromosome architecture are playing and will play in the near future were highlighted in order to investigate composition of the transcription factories assembled in response of a specific trigger: The estrogen‐sensitive transcription was cited but the authors are convinced that the same portrait will be observed with a multitude of (if not all) other stimuli
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
