Persistenza di elvata pressione intraoculare dopo filtranti protette: frequenza, cause e trattamenti
No full textAnalysis of fibronectin, plasminogen activators and plasminogen/plasmin in tear fluid as markers of corneal damage and repair
No full textCorneal damage of various origins initiates a series of processes which lead to repair but also tend to perpetuate the damage; healing thus depends on the prevalence of repair over progression processes. The plasminogen/plasmin system has an important impact on this process, particularly by degrading the extracellular matrix components with resulting interference of the repair processes. This paper presents the immunoblotting analysis of fibronectin, tissue and urokinase-type plasminogen activators and plasminogen/plasmin in the tear fluid of control subjects and patients affected by various ocular pathologies (corneal ulcers, thermal or chemical burns, herpetic keratitis). A significant modification was noted in the protein profiles of fibronectin, tissue and urokinase-type plasminogen activators and plasminogen/plasmin in the cases of corneal ulcers and thermal or chemical burns relative to the pattern observed in the control subjects, while in cases of herpetic keratitis, only plasminogen/plasmin showed slight variations. The altered protein patterns gradually normalized during therapeutic treatment and, at remission, coincided with those of the control subjects

No full textSixty-eight eyes presenting with congenital glaucoma and operated on by goniotomy, have been followed up for 1 to 10 years. Intra-ocular pressure was normalized in 91.18 p. cent of cases by one or more goniotomies with or without medical treatment. We have also analyzed the functional results of these operations
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
