Morphological, Mechanical and Hydrodynamic Aspects of Diaphragmatic Lymphatics
Full text linkThe diaphragmatic lymphatic vascular network has unique anatomical characteristics. Studying the morphology and distribution of the lymphatic network in the mouse diaphragm by fluorescence-immunohistochemistry using LYVE-1 (a lymphatic endothelial marker) revealed LYVE1+ structures on both sides of the diaphragm—both in its the muscular and tendinous portion, but with different vessel density and configurations. On the pleural side, most LYVE1+ configurations are vessel-like with scanty stomata, while the peritoneal side is characterized by abundant LYVE1+ flattened lacy-ladder shaped structures with several stomata-like pores, particularly in the muscular portion. Such a complex, three-dimensional organization is enriched, at the peripheral rim of the muscular diaphragm, with spontaneously contracting lymphatic vessel segments able to prompt contractile waves to adjacent collecting lymphatics. This review aims at describing how the external tissue forces developing in the diaphragm, along with cyclic cardiogenic and respiratory swings, interplay with the spontaneous contraction of lymphatic vessel segments at the peripheral diaphragmatic rim to simultaneously set and modulate lymph flow from the pleural and peritoneal cavities. These details may provide useful in understanding the role of diaphragmatic lymphatics not only in physiological but, more so, in pathophysiological circumstances such as in dialysis, metastasis or infection

No full textStampa studentesca e Digital Library: l’esperienza dell’Università di Bologna
No full textViene presentato il progetto di digitalizzazione delle riviste dell'Archivio storico dell'Università di Bologna. Esso ha riguardato soprattutto la collezione di numeri unici studenteschi databili dalla fine dell'Ottocento alla prima metà del Novecento. Oltre al lavoro di digitalizzazione condotto secondo gli standard ICCD, il progetto ha compreso la messa in rete dell'intera collezione digitalizzata sul sito della Digital Library dell'Ateneo di Bologna e sull'edicola digitale del sito dell'Archivio storico (http://db.archiviostorico.unibo.it/it-it/edicola-degli-studenti/elenco-delle-riviste.aspx?idC=61686&LN=it-IT#)

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
