In Vitro Cyto- and Genotoxicity Assessment of Antibacterial Paints with Triclos...
Querido, Micaela; Rosário, Fernanda; Bessa, Maria; Mendes, Francisca; Teixeira, José; Teixeira, João; Pereira, CristianaSurfaces with antimicrobial properties are gaining notoriety as an efficient method to avoid surface contamination. Self-disinfecting paints are a promising strategy towards cleaner indoor environments by preventing the colonization of walls with microorganisms. However, its widespread use needs an appropriate toxicological safety evaluation due to the potential for biological disturbance associated to its bioc...
Elderly exposure to fungi: a review study
Almeida-Silva, Marina; Pereira, CristianaIndoor air quality is an increasing concern since people spend 90% of their time indoors. The majority of exposure to air pollution happens indoors rather than outdoors, despite the focus being on the latter. Indoor air quality in elderly care centers (ECC) is an emerging important issue arising in the last decade because of the increase in life expectancy, the number of individuals residing in ECC, and populat...
Development of Self-disinfecting Paints and In Vitro Assessment of their Cytoto...
Querido, Micaela; Paulo, Ivo; Galhano Santos, Rui; Bordado, João; Teixeira, João Paulo; Pereira, CristianaThis PhD project aims to develop, test and validate a self-disinfecting paint, to be applied in areas with a high propensity for infection spreading, such as healthcare facilities, schools or other public spaces, to help reduce infection risks.
Assessment of gamma oryzanol variability, an attractive rice bran bioactive com...
Lageiro, Manuela; Castanho, Ana; Pereira, Cristiana; Calhelha, Ricardo C.; Ferreira, Isabel C.F.R.; Brites, CarlaGamma-oryzanol is a compound present on rice bran, which has been studied for its bioactive properties, including its cytotoxic activity. The gamma-oryzanol biosynthesis occurs on the lipidic membrane of the plant and can be influenced by edaphoclimatic grown conditions. Two Portuguese rice varieties (Ceres and Macarico) from 6 growing environments were analysed in order to explore the influence of the growing ...
Exposure assessment in one central hospital: a multi-approach protocol to achie...
Viegas, Carla; Almeida, Beatriz; Monteiro, Ana; Paciência, Inês; Rufo, João; Aguiar, Lívia; Lage, Bruna; Diogo Gonçalves, Lídia MariaThe bioburden in a Hospital building originates not only from patients, visitors and staff, but is also disseminated by several indoor hospital characteristics and outdoor environmental sources. This study intends to assess the exposure to bioburden in one central hospital with a multi-approach protocol using active and passive sampling methods. The microbial contamination was also characterized through molecul...

Análise do conforto térmico em estruturas residenciais para idosos em clima atl...
Torres, Pedro; Aguiar, Lívia; Pereira, Cristiana; Forcada, Nuria; Tejedor, Blanca; Neves, Maria Paula; Teixeira, João Paulo; Mendes, AnaA esperança média de vida da população mundial tem vindo a aumentar, incrementando a faixa etária acima dos 65 anos. Nesse sentido, determinados ser viços experimentam maior demanda em resposta às necessidades crescentes desta população, como é o caso dos ser viços de cuidados a longo prazo, nomeadamente, centros de dia (CD) e estruturas residenciais para idosos (ERPI). Neste âmbito de ser viços para a comunida...
Aspergillus spp. prevalence in one Portuguese hospital: a reason to be worried?
Viegas, Carla; Dias, Marta; Almeida, Beatriz; Paciência, Inês; Rufo, João Cavaleiro; Teixeira, João Paulo; Pereira, CristianaAspergillus genus is responsible for over 80% of pulmonary invasive fungal infections in humans. Invasive aspergillosis, caused by Aspergillus fumigatus in 80% of the cases, is the most common invasive fungal infection. The aim of this study was to assess the prevalence of Aspergillus genus in a Portuguese hospital, using a wide sampling approach combining active and passive methods. A total of 15 sampling site...
Construção com base em terra: contributo para a ecoeficiência na construção
Gomes, Maria; Santos, Tânia; Pereira, Cristiana; Faria, PaulinaA terra é dos mais antigos materiais de construção, existindo registos da sua utilização desde o período pré-histórico. Utilizada na construção de um vasto património edificado, como fortificações, residências nobres, igrejas, mosteiros, habitação e apoios agrícolas, entre outros, a utilização da terra apresenta inúmeras vantagens, nomeadamente, económicas, ecológicas e de conforto interior, devido à capacidade...
Hospital environment: a safe place to be when using Portuguese legislation as g...
Viegas, Carla; Almeida, Beatriz; Paciência, Inês; Rufo, João Cavaleiro; Pereira, CristianaExposure to bioburden (comprising bacteria and fungi) has become one of the critical issues for occupational and public health approaches in the hospital environment. This study aims to assess the fungal burden in one Central Hospital in Oporto, Portugal, applying the Indoor Air Quality (IAQ) Portuguese legislation as guidance, verifying both the limit values and the conformity established for general indoor en...
