Influenza dell'azione degli antiossidanti nella capacità fecondante dei gameti maschili e femminili
No full textA significant reduction in spermatozoa’s and ovocites’s level antioxidants has been reported as cause of susceptibility of these cells to peroxidative injuries after cryopreservation andin vitromaturation (IVM). The aim of this study was to investigate whether there are qualitative differences of antioxidant capacity content in follicular fluids collected from ovarian follicles in seminal plasma and sperm cell extract among boar and ram at different times of the year. Samples were processed rapidly and kept frozen at − 80 °C until assayed. TEAC, SOD, MDA and ROMs of PFF, seminal plasma and sperm cell extract was determined using assays as described in literature and modified. Obtained results showed statistically significant differences for all PFF’s assays, while for boar semen’s d-Roms test, MDA and seminal plasma’s SOD wasn’t s statistically significant differences. In ram’s semen, only Roms’ assay wasn’t statistically significant.Our results suggest that that the quality of the follicular fluid (and the ability to increase the IVM) as well as quality of boar and ram semen, may be linked to their oxidative state. This finding can be applied to develop protocol to optimize IVM in pig and optimize semen cryopreservation protocols, but may also have an application in developing therapeutic protocols for male infertility related to a decrease in sperm antioxidant defense system
Addis Ababa Living Lab: Spatial Mapping
No full textThis research booklet brings together a selection of data and spatial analysis of Ethiopia’s and Addis Ababa’s urban transformation. This booklet uses historical maps, new maps and a selection of bibliographic references, to produce a wide range of graphic outputs that trace the urban transformation of Addis Ababa in seven stages, from its foundation (c. 1887) until the current process of urbanisation under the auspices of globalization.This report was produced as part of the Global Housing Graduation Studio of Architecture & Dwelling from the Faculty of Architecture and the Built Environment. The studio was set up as a supportive educational component in the research project ‘Addis Ababa Living Lab’ (2019-2023), jointly funded by NWO-WOTRO and TU Delft.Architecture, Urbanism and Building Sciences | Global Housin
Setting proteins free : progresses and achievements in proteomics of formalin-fixed, paraffin-embedded tissues
No full textFormalin fixation, followed by paraffin embedding, is long established as the standard procedure for the stabilization and preservation of tissue architecture, essential for enabling microscopic examination and long-term storage of samples. During the years, this has led to the generation of a worldwide repository of patient tissues with associated complete clinical records. As such, this represents a golden mine for all those attempting to identify proteomic signatures of disease, aimed to the understanding of pathological processes and to the identification of new biomarkers. However, access to this resource has been hampered by the stable cross-linked network generated on tissue molecules during formalin fixation. Recently, researchers have been actively working to overcome this limitation, reaching unexpected achievements. This review aims to discuss and compare the various strategies devised for extracting full-length proteins or peptides from fixed tissues, and to provide a general perspective on studies comparing matched fixed and fresh-frozen tissue proteomes, applying proteomic techniques for biomarker discovery from archival tissues, and attempting to exploit gel-based approaches. In addition, the concomitant progresses in understanding the impact of tissue processing variables and the extent and nature of formaldehyde-induced modifications are presented. In conclusion, the future perspectives and open challenges in this field are discussed
Variations on the Author
No full text“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
Imparare le lingue per abbracciare il mondo
No full textL’autrice che si colloca, come Daniela Zorzi, tra i fautori di una linguistica “impegnata”, propone in ricordo della studiosa amica, una riflessione sul ruolo cruciale del multilinguismo e delle lingue- culture, per il successo professionale e il benessere sociale, nella società contemporanea. Il multilinguismo appare come un’urgenza educativa che interpella studiosi e formatori a tutti i livelli al fine di promuovere nei giovani un apprendimento consapevole efficace ed autonomo.Multilingualism constitutes an urgent objective for education, which needs to involve teachers and researchers at all levels if we are to promote effective and autonomous learning in the young. Like Daniela Zorzi, the author considers herself a socially engaged linguist, and in memory of her friend’s work, offers a reflection on the key roles of languages and cultures and of multilingualism for professional success and social welfare today
Reclamações ambientais em Aveiro, Portugal: atores, preocupações, padrão territorial e resoluções
No full textThis paper presents an environmental diagnosis based on public complaints on environmental
issues submitted to the Environmental Department of the Aveiro City Council, Portugal, between
2000 and 2005. It discusses the potential influences of these in local environmental planning
and governance. The paper has been organised into five sections. The first of these introduces
the study. The second section focuses on the conceptual approaches relating to environmental
grassroots movements, the main actors involved in these movements and the role played by
local government. It also contains a brief review of the most recent urban environmental
quality challenges in the European context together with a description of the main features of
the associated political and legal framework in Portugal. The third section describes the case
study and the methodology used. The results of the empirical study are detailed in the fourth
section. The final section critically analyses these results with emphases on the temporal
evolution of the submission of complaints, the actors involved, the local environmental problems
and their associated spatial pattern as well as the responses given by the City Council. This
information may then be used to provide a useful indicator for the perception of environmental
quality as well as a credible instrument for the visualisation and evaluation of local performance
in terms of environmental planning and management.AlBan Programme - n. E05M053040B

Interactions between Reflection and Praxis in the History of Economic Thought. The case of the Franciscan Cicles from XIII Century Assisi to the Present
No full textResumen: Daniela Parisi analiza el impacto de la vida de San F rancisco de Asís desde la perspectiva de la historia del pensamiento económico. Haciendo referencia particularmente a la atención otorgada en los círculos franciscanos a los signos de los tiempos, la autora traza el camino desde la vida de San Francisco, pasando por la vida de la Orden hasta el presente, y revela los orígenes del movimiento franciscano como un intento de reforma social y religiosa. En primer lugar, el artículo presenta la vida que llevó San Francisco como una “pobreza material voluntaria” en el contexto de los cambios socio-económicos que tuvieron lugar en el siglo XIII, con el advenimiento de la sociedad comercial. Luego, explica cómo la propuesta de San Francisco creció hasta convertirse en una orden religiosa. Finalmente, el artículo intenta iluminar aquellos aspectos en que la Orden Franciscana puede todavía considerarse un signo de los tiempos a través de una existencia comprometida con la pobreza, eliminando lo superfluo de nuestra vida y viviendo en consonancia con el Evangelio.Abstract: Daniela Parisi analyses the impact of the life of Saint Francis of Assisi, from the perspective of the history of economic thought. By referring in particular to the attention given in Franciscan circles to the signs of times, the author draws the path from Saint Francis’s life to the life of the Order until the present, and reveals the origins of the Franciscan movement as an attempt for social and religious reformation. First, the article presents St. Francis’s life of a “voluntary material poverty” in the context of the social and economic changes that took place in the XIII century, with the rise of the commercial society. Then, the author explains how St. Francis’ proposal grew into an Order. Finally, the article aims at illuminating the aspects in which the Franciscan Order can be still considered a sign of the times by living the commitment to poverty and minority, eliminating the superfluous from our lives and living close to the Gospel
