Hazard characterization of the mycotoxins enniatins and beauvericin to identify...
Behr, AC; Fæste, CK; Azqueta, A; Tavares, AM; Spyropoulou, A; Solhaug, A; Olsen, AK; Vettorazzi, A; Mertens, B; Zegura, B; Streel, C; Ndiaye, DEnniatins (ENNs) and beauvericin (BEA) are cyclic hexadepsipeptide fungal metabolites which have demonstrated antibiotic, antimycotic, and insecticidal activities. The substantial toxic potentials of these mycotoxins are associated with their ionophoric molecular properties and relatively high lipophilicities. ENNs occur extensively in grain and grain-derived products and are considered a food safety issue by t...
Anti-corrosion and cytotoxicity properties of inorganic surface treatments on M...
Neves, CS; Sousa, I; Freitas, MA; Moreira, L; Costa, C; Teixeira, JP; Fraga, S; Silva, RM; Silva, RF; Starykevich, M; Scharnagl, N; Zheludkevich, MLIn this work biodegradable Mg1Ca alloy underwent surface modification using hydroxyapatite (HAp), aluminium oxide (Al2O3), and treatments with phosphoric (H3PO4), hydrofluoric (HF), and acetic (CH3COOH) acids. The resulting surface-treated Mg substrates were assessed in terms of phase content and chemical composition through X-ray diffraction (XRD) and glow discharge optical emission spectrometry (GDOES). Addit...
Incidental nanoparticle characterisation in industrial settings to support risk...
Moreno-Martín, V; López, M; Bou, D; Fraga, S; Teixeira, JP; López-Lilao, A; Sanfélix, V; Monfort, E; Viana, MResearch on nanoparticle (NP) release and potential exposure can be assessed through experimental field campaigns, laboratory simulations, and prediction models. However, risk assessment models are typically designed for manufactured NP (MNP) and have not been adapted for incidental NP (INP) properties. A notable research gap is identifying NP sources and their chemical, physical, and toxicological properties, ...
Potential human exposure and risks of incidental nanoparticles released during ...
Moreno-Martín, V; López, M; Roldan, C; Bou, D; Fraga, S; Teixeira, JP; López-Lilao, A; Sanfélix, V; Moliner, R; Monfort, E; Viana, MRotary dry cutting and rectifying of ceramic tiles are sources of fine particulate matter (PM2.5) and nanoparticles (NPs). These activities are typically carried out inside industrial facilities during the manufacturing process, as well as outdoors and in residential indoor spaces during the installation phase, where mitigation measures are seldom implemented. This work aimed to understand the particle formatio...
Association between adverse childhood experiences and bodily pain in early adol...
Abrahamyan, A; Lucas, R; Severo, M; Talih, M; Fraga, SWe aimed to examine the relationship between lifetime exposure to adverse childhood experiences (ACEs) during the first decade of life and recent pain features reported in early adolescence. We conducted a prospective study using data from 4564 adolescent Generation XXI birth cohort participants recruited in 2005–2006. Adverse childhood experiences were reported by children at ages 10 and 13 years using a 15-it...
The Interaction Effect of Adverse Childhood Experiences and Socioeconomic Circu...
Abrahamyan, A; Severo, M; Soares, S; Fraga, S; Amorim, M"Purpose Limited research has examined the combined effects of psychosocial and material adversities experienced in childhood during adolescence, a sensitive period of rapid social, emotional, and cognitive development. We investigated the interaction effect of adverse childhood experiences (ACEs) and socioeconomic circumstances (SECs) during childhood on emerging self-reported depressive symptomatology among 1...
Stressful life events and heart disease and stroke: A study among Portuguese ol...
Quaresma, A; Alves, E; Fraga, S; Henriques, AThe link between stressful life events (SLE) and cardiovascular diseases (CVD) remains underexplored. This study aimed to examine the association between SLE and the diagnosis of heart disease or stroke, among older adults. Data from 678 participants from the population-based cohort EPIPorto, with >= 60 years and complete information regarding SLE and heart disease or stroke, were analysed. Stressful life event...
“Older people are weak”: perceptions and meanings of ageing and abuse against o...
Dias, I; Fraga, SIntroduction: This paper addresses the broader issue of elder abuse and seeks to analyse how victims and non-victims of abuse connect and explain the perception of ageing and the phenomenon of violence against older people. Methods: A qualitative study was conducted based on evidence gathered through 45 semi-structured interviews with people aged 60 or above who are part of the Portuguese EPIPorto population co...
Prevalence of Parental Violent Discipline Toward Children: Findings From A Port...
Abrahamyan, A; Soares, S; Fraga, S; Barros, HDespite recognizing the detrimental impact of parental violence on children’s mental and physical health throughout their lives, violence remains an all-too-real part of life for many children around the globe. However, data on the child-reported prevalence of experienced family violence are scarce and primarily based on parental reports. This study aimed to broaden the body of evidence and measure the lifetime...
Women's voices and meanings of empowerment for reproductive decisions: a qualit...
Castro Lopes, S; Constant, D; Fraga, S; Harries, JBackground: Women in Mozambique are often disempowered when it comes to making decisions concerning their lives, including their bodies and reproductive options. This study aimed to explore the views of women in Mozambique about key elements of empowerment for reproductive decisions and the meanings they attach to these elements. Methods: Qualitative in-depth interviews were undertaken with 64 women of reproduc...
