Massa vulvar – a ponta do iceberg

Uterine fibroids are benign monoclonal tumors that originates from the smooth muscle cells of the myometrium and are the most common solid pelvic tumors in women. In the differential diagnosis of vulvar masses we should considered Bartholin's cysts or abscesses, Bartholin's tumors, fibroids (usually fibroids of the round ligament), subcutaneous lipomas, inguinal hernia or adenomegaly. With this images we present a case of a vulvar mass caused by a fibroid, probably from the round ligament, which was a tip of the iceberg of an extensive pelvic leiomyomatosis.info:eu-repo/semantics/publishedVersio

Higher education institutions and international students’ hindrances: a case of students from the African Portuguese-speaking countries at two European Portuguese universities

We present a study to comprehend if the support given by higher education institution (HEI) to international students coming from the PortugueseSpeaking African Countries meets their academic and social hindrances. Our starting point was a set of semi-structured interviews focused on the perspectives of these students, their Professors and Course Directors as well as on the perspectives of HEI’ staff. Despite findings indicate a positive institutional support, it seems there is still much to do in order to do it properly with these students. These different perspectives will allow us to reflect on the impact that those actions/resources have on the path of students from Portuguese-Speaking African Countries and to systematize suggestions to enhance their experiences in HE.info:eu-repo/semantics/publishedVersio

Notas sobre uma gestão cultural independente

O presente texto é um conjunto de notas sobre o modelo de gestão de arte do espaço "Uma Certa Falta de Coerência", situado na cidade do Porto, e a oportunidade de apresentar algumas reflexões sobre a forma como este espaço se insere no quotidiano dos seus mentores. A reflexão tem como pano de fundo a teorização de Mike Featherstone no que diz respeito à estetização do quotidiano e apoia-se em Jacques Rancière na relação da estética com a política

A Shared Pilgrimage Road in Israel and Palestine: From Utopia to Reality

Most pilgrimages on foot are not a journey undertaken for comfort. Pilgrims going on foot are challenged in multiple forms. Probably to have the physical energy to accomplish the distances of each pilgrimage day is a common goal, also having time to reflect and to meditate is a common characteristic, independent from each pilgrim’s religious belief. Along the Way pilgrims live ‘slow’ experiences, involving themselves with what surrounds them. In those occasions, for most pilgrims, there is an opportunity for better understanding the importance of living in peace in a common world. Having in mind the Israeli-Palestinian geographic area, the numerous holy places which are important for the Abrahamic religions, and the sustainable development of rural areas, this paper emphasises the importance of developing a Pilgrimage Road (for pilgrimages on foot) in these regions. Most times a Pilgrimage Route is only linked to a specific religious belief. The one to be proposed would possibly be one of the very few pilgrimage ways shared by different religions; in this case, Judaism, Christianity, and Islam, or in other words, shared by the Abrahamic religions

Retinal biomarkers of Alzheimer’s disease: insights from transgenic mouse models

In this paper, we use the retina as a window into the central nervous system and in particular to assess changes in the retinal tissue associated with the Alzheimer’s disease. We imaged the retina of wild-type (WT) and transgenic mouse model (TMM) of Alzheimer’s disease with optical coherence tomography and classify retinas into the WT and TMM groups using support vector machines with the radial basis function kernel. Predictions reached an accuracy over 80% at the age of 4 months and over 90% at the age of 8 months. Texture analysis of computed fundus reference images suggests a more heterogeneous organization of the retina in transgenic mice at the age of 8 months in comparison to controls.This study was supported by the Neuroscience Mantero Belard Prize 2015 (Santa Casa da Misericórdia)(MB-1049-2015), by The Portuguese Foundation for Science and Technology (PEst-UID/NEU/04539/2013), by FEDER-COMPETE (POCI-01-0145-FEDER-007440) and Centro 2020 Regional Operational Programme (CENTRO-01-0145-FEDER-000008: BrainHealth 2020).info:eu-repo/semantics/publishedVersio

Development of methodologies for validating the quality of a novel fluid flow sensor

During the internship required for the Master's degree in Biomedical Engineering, conducted at Riedel Communications, a systematic review of the literature was developed in order to gain a greater understanding of methods for validating the quality of sensors, with a main focus on calibrations. A second assignment involved calibrating the fluid flow sensor (FFS) developed by Riedel. Throughout this dissertation, the work carried out during the internship will be described, as well as its background and objectives. Riedel Communications is developing a scientifically precise and high-quality system for acquiring 3D navigation data. The idea was born out of the need to obtain analytical data that better reflects the movement of a surfer relative to the water. A fluid flow sensor (FFS) is integrated into the system, and its implementation in hostile environments and measurement without interfering with an athlete's performance are the biggest challenges. In order to ensure consistency and reduce errors, all instruments should be calibrated to ensure they are performing in accordance with known standards. Based on the high consistency and repeatability of the experimental results, the fluid flow sensor displayed a high-quality performance. Therefore, the internship was a success because it served as a valuable resource for the company's work, and all activities were successfully completed.Durante o estágio do Mestrado em Engenharia Biomédica, realizado na Riedel Communications, foi desenvolvida uma revisão sistemática da literatura a fim de se obter uma maior compreensão dos métodos de validação da qualidade de sensores, sendo que a calibração foi o foco principal. Num segundo trabalho, procedeu-se exatamente à calibração do sensor de fluxo desenvolvido pela Riedel. Ao longo deste relatório, será descrito o trabalho realizado durante o estágio, bem como os seus objetivos. A Riedel Communications está a desenvolver um sistema cientificamente preciso e de alta qualidade para a aquisição de dados de navegação 3D. A ideia nasceu da necessidade de obter dados analíticos que reflitam melhor o movimento de um surfista em relação à água. Um sensor de fluxo de fluido (FFS) está integrado no sistema, e a sua implementação em ambientes hostis e medição sem interferir com o desempenho de um atleta são os maiores desafios. A fim de assegurar a consistência e reduzir erros, todos os instrumentos devem ser calibrados para garantir que o seu desempenho está de acordo com as normas conhecidas. Com base na elevada consistência e repetibilidade dos resultados das experiências efetuadas, pode-se dizer que o sensor de fluxo de fluido apresentou um desempenho de alta qualidade. Portanto, o estágio foi um sucesso pois serviu como um recurso valioso para o trabalho da empresa, e todas as atividades foram concluídas com sucesso
