Abstract:

The Coronavirus disease 2019 (COVID-19) outbreak have shown that there may be sex-dependent differences in morbidity and mortality among individuals contracted with the disease. The aim of the study was to analyse the extent that sex differences appear in COVID-19 infections and to explore whether any differences are due to intrinsic factors in the sexes that cause sex-bias in the disease susceptibility and mortality. The study presents an age and sex-disaggregated analysis of reported cases of total infections, intensive care cases, and deaths across 13 countries due to the disease. The resul

Le cancer bronchique, ou pulmonaire, est la première cause de décès dans le monde par cancer. Le traitement repose sur la chirurgie, quand la tumeur est résécable, et sur un traitement adjuvant associant généralement la chimiothérapie à la radiothérapie, l'immunothérapie ou les thérapies ciblées.Les patients atteints de cancer du poumon non à petites cellules (CBNPC) sont fréquemment exposés à des infections virales telles l'Influenza A (IAV) ou le SARS-CoV-2.

Abstract:

Health is often defined in terms of absence of disease or pathological processes, but this is a definition of exclusion and incomplete. For example, SARS-CoV-2 viral load does not reliably predict disease severity, and so individuals must vary in their ability to control inflammation and maintain normal tissue homeostasis. This host defense strategy is called disease tolerance, and better understanding of disease tolerance mechanisms could change the way that we treat disease and work to maintain health.

Zinc is an essential trace element with structural, catalytic and signaling roles in our body.

The first goal of this thesis is to explore the role of zinc during the metastasis of triple negative breast cancer to the brain.

The COVID-19 pandemic has been having a strong impact throughout the world, changing the way we live our lives. This is due to the threat that the virus poses to human health, but also to the impact it has on waste management and consequently the environment. In this dissertation it was intended to study the way that the pandemic has been affecting waste management. With the elaboration of two interviews, it was intended to understand the role that the municipal governments of Lisbon (Portugal) and Salto (Brazil) had on waste management during the pandemic and if the management process has be

Abstract:

In the global context, particularly in India, the two most important infectious diseases among many others are Tuberculosis (TB), an age-old disease and COVID-19, a new-age disease. This thesis focuses on some of the key proteins responsible for their pathogenesis. In the second chapter, structural and functional characterization of Cystathionine-β-synthase from Mycobacterium tuberculosis (Mtb) was done using single-particle cryo-electron microscopy. CBS is the first enzyme of the transsulfuration pathway. This pathway produces hydrogen-di-sulfide (H2S) that scavenge reactive oxygen specie

Abstract:

O presente relatório surge como um documento representativo do meu percurso e aprendizagens alcançadas, na procura de um saber especializado. Inseridos no Mestrado em Enfermagem Médico-Cirúrgica, na área da pessoa em situação crítica, os estágios descritos realizaram-se no serviço de urgência e na comissão de controlo de infeção, de uma unidade local de saúde do distrito do Porto. Na atualidade, os cuidados de saúde têm sido diariamente desafiados pela pandemia COVID-19. Os efeitos pandémicos foram efetivamente desastrosos e de difícil superação. Não só pelo seu impacto orgânico, traduzido p

Abstract:

A urbanização é uma das grandes mudanças demográficas mais relevantes do mundo, no entanto é considerada um dos maiores fatores de risco para a saúde humana. Apesar das cidades fornecerem um melhor estilo de vida à população, devido a apresentarem melhor acesso a cuidados de saúde, melhores condições de vida, tendo em consideração fatores culturais, sociais e económicos. No entanto, a vida nas cidades apresenta também inúmeras consequências negativas. O número de pessoas que migram das áreas rurais para as urbanas é cada vez maior, assim sendo prevê-se que no ano de 2050 a população mundial

Abstract:

O vírus SARS-CoV-2 identificado em humanos em 2019, na China, provocou uma pandemia mundial a COVID-19, decretada pela Organização Mundial de Saúde em Março de 2020. Nas características deste Coronavírus destacam-se a elevada transmissibilidade por gotículas respiratórias e fómites e os sintomas podem variar de leves a moderados ou ser tão graves que podem mesmo levar à morte. As medidas de prevenção adotadas mundialmente foram decisivas no controle da pandemia enquanto não se desenvolveram vacinas e medicamentos antivirais eficazes. O distanciamento social, o uso de máscaras faciais e as desi

Abstract:

Nesta dissertação pretende-se perceber e identificar as principais alterações bioquímicas que ocorrem nas doenças infeciosas, nomeadamente na COVID-19, SIDA, tuberculose, infeções com Helicobacter pylori, Tinea corporis e toxoplasmose. Nesse sentido, foi alvo de análise o reconhecimento dos possíveis marcadores bioquímicos de cada doença, sendo realçada a forma como os mesmos podem ser utilizados no diagnóstico. Adicionalmente, foram identificados os tratamentos e fármacos empregues em cada patologia, bem como apresentadas as moléculas que se encontram disponíveis no mercado. Foi realizada um
