Students' summer internships in a research centre: the impact on scientific lit...
Saraiva, Elisa; Silva, Sónia Carina; Castro, Joana Isabel Reis; Araújo, Daniela; Almeida, Carina Manuela Fernandes; Azevedo, Maria ManuelScience communication is crucial for engaging society in real-life contexts. In this line of thought, research centres play a pivotal role in promoting dynamic and interactive communication that enables science to be disseminated. This study constitutes a qualitative research based on a case study involving middle school students, researchers and teachers, which took place in a research centre in Portugal that ...
A União Europeia como 'Potência Modelo' na gestão da pandemia COVID-19: o caso ...
Azevedo, Maria ManuelA presente dissertação analisa as ações e estratégias adotadas pela União Europeia (UE) com destaque para a Comissão Europeia no contexto da gestão da pandemia COVID-19 entre 11 de março de 2020 e 5 de maio de 2023, data das declarações oficiais do início e fim da pandemia pela Organização Mundial da Saúde (OMS), respetivamente. O cerne desta análise residiu na compreensão e avaliação das medidas implementadas ...
Microbes and cancer: friends or faux?
Azevedo, Maria Manuel; Pina-Vaz, Cidália; Baltazar, FátimaCancer is one of the most aggressive and deadly diseases in the world, representing the second leading cause of death. It is a multifactorial disease, in which genetic alterations play a key role, but several environmental factors also contribute to its development and progression. Infections induced by certain viruses, bacteria, fungi and parasites constitute risk factors for cancer, being chronic infection as...
How to decipher a microbial puzzle on microbial control: hands on
Azevedo, Maria Manuel; Pinheiro, Céline; Miranda, Isabel; Baltazar, FátimaAntibiotics are among the most commonly prescribed drugs, but they are often misused, contributing to bacterial resistance, being an important public health problem, with clinical/economic impacts. Aiming to contribute to convey information to students on Microbiology/antibiotic use, we developed different teaching activities, with 6th and 9th grade students. To assess the impact of these activities and student...
The impact of alternative science education methodologies on the motivation and...
Azevedo, Maria Manuel; Fonseca, Fernando; Andrade, Raquel P.; Palmeirim, I.Fully aware of the increasing importance of active and experimental learning, this study has been conducted in Portugal between 2007 and 2008 and was the first of this kind to ever be conducted in this country. Thirty eight students of the school E.B. 2, 3 D. Maria II (middle school) participated in the extra-curricular activity entitled “Scientists for a Day”, previous developed by the Life and Health Science ...
The impact of experimental activities on the motivation and acquisition of scie...
Azevedo, Maria Manuel; Fonseca, Fernando; Brito, C.; Andrade, Raquel P.; Palmeirim, I.; Teixeira, Alexandra Sofia PereiraForty students (middle school) participated in the science activity entitled “Scientists for a Day”, developed by the Life and Health Science Research Institute/School of Health Science, University of Minho. The activity consisted in a set of laboratory activities. The general objectives of this activity were to stimulate the pleasure of knowledge, encourage critical views, heighten the interest in science, mot...
Portuguese students' knowledge of antibiotics: a cross-sectional study of secon...
Azevedo, Maria Manuel; Pinheiro, Céline; Yaphe, John; Baltazar, FátimaBACKGROUND: Recent surveys show that the knowledge of the general public about the correct use of antibiotics is limited. This contributes to the problem of inappropriate antibiotic use, leading to a progressive loss of bacterial sensitivity to these drugs and the spreading of resistant strains of bacteria. METHODS: In this cross-sectional study, a questionnaire about antibiotic use was given to a sample of stu...
Toxicity of metals in aquatic hyphomycetes : cellular targets and defense mecha...
Azevedo, Maria ManuelHuman activities contribute to a high release of heavy metals to the environment at rates and concentrations sufficient to make them pollutants. Certain metals, such as Cu and Zn, are needed for the growth and metabolism of organisms, while others, as Cd, have no recognized biological functions. However, above critical levels, both essential and non-essential metals became toxic to living organisms. Aquatic hyp...
Copper and zinc stress in aquatic fungi: the role of cellular antioxidant defences
Azevedo, Maria Manuel; Carvalho, André; Pascoal, Cláudia; Rodrigues, Fernando José dos Santos; Cássio, FernandaAquatic hyphomycete species play an important role in biogeochemical cycles, being the main decomposer fungi of plant detritus in streams. Pollution by heavy metals in freshwaters is currently a worldwide problem, especially in industrial areas. Above threshold concentrations, metal ions are known to promote reactive oxygen species (ROS) formation that may overwhelm the cellular antioxidant defences. Our resear...
