Association between exposure to airborne endocrine disrupting chemicals and ast...
Hatem, G; Faria, AM; Pinto, MB; Teixeira, JP; Salamova, A; Costa, C; Madureira, JVarious studies have explored the association between Endocrine Disrupting Chemicals (EDCs) exposure and children's and adolescents' respiratory health, showing potential long-term effects and links to asthma. This systematic review explores the association between exposure to seven EDC groups during school age and adolescence and asthma onset or exacerbation while highlighting the predominant compounds underly...
In vitro and in vivo assessment of nanoceria biocompatibility for their safe us...
Fernández-Bertólez, N; Martínez, L; Ramos-Pan, L; Touzani, A; Costa, C; Laffon, B; Valdiglesias, VNanoceria, or cerium dioxide nanoparticles (CeO2 NP), are increasingly employed in a number of industrial and commercial applications. Hence, the environmental presence of these nanoparticles is growing progressively, enhancing the global concern on their potential health effects. Recent studies suggest that nanoceria may also have promising biomedical applications particularly in neurodegenerative and brain-re...
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...
Novel Fermented Plant-Based Functional Beverage: Biological Potential and Impac...
Vila-Real, C; Costa, C; Pimenta-Martins, A; Mbugua, S; Hagrétou, S-L; Katina, K; Maina, NH; Pinto, E; Gomes, AMPControlled fermentation carried out by selected starters might enhance the safety, nutritional, and biological profiles of non-dairy fermented products. This research aims to study the biological potential and impact on the human gut microbiota of a novel fermented finger millet-based product. Finger millet (Eleusine coracana), suspended in an aqueous sucrose-based solution, was fermented by Weissella confusa 2...
Exposure to per-and poly-fluoroalkyl substances and respiratory and skin effect...
Hatem, G; Faria, AM; Pinto, MB; Salamova, A; Teixeira, JP; Costa, C; Madureira, JDespite being previously banned due to long-term health effects, Per- and polyfluoroalkyl substances (PFAS) remain widespread in the environment, accumulating in animals and humans. This systematic review and meta-analysis explores associations between exposure to PFAS and asthma onset, wheezing, atopic dermatitis, and eczema in children and adolescents while addressing exposure timing and sex-specific differen...
General Knowledge and Attitudes about Safety and Emergency Evacuation: The Case...
Carvalhais, C; Dias, R; Costa, C; Silva, MVThe implementation of a safety culture and awareness of emergency issues in buildings has been growing in more developed societies. It is essential that all occupants know how to act in an emergency situation, particularly during an emergency evacuation. In higher education institutions (HEIs), which annually host not only their many employees, but also national and international students, it is essential to kn...
Impact of a legumes diet on the human gut microbiome articulated with fecal and...
Ferreira, H; Duarte, D; Carneiro, TJ; Costa, C; Barbosa, JC; Rodrigues, JE; Alves, P; Vasconcelos, M; Pinto, E; Gomes, A; Gil, AMBackground & aims: Legumes intake is known to be associated with several health benefits the origins of which is still a matter of debate. This paper addresses a pilot small cohort to probe for metabolic aspects of the interplay between legumes intake, human metabolism and gut microbiota. Methods: Untargeted nuclear magnetic resonance (NMR) metabolomics of blood plasma and fecal extracts was carried out, in tan...
Porque é que Ele Anda Assim? Marcha em Pontas e Perfil Sensorial
Pires, S; Costa, C; Martins, MT; Pereira, S; Martins Halpern, C; Neiva, S; Paiva Gomes, M; Caldeira da Silva, PA marcha em pontas (MP) define-se pela ausência de contacto do calcanhar com o solo na fase inicial da marcha, podendo ser normal durante a aprendizagem motora, associar-se a diferentes patologias ou ser idiopática (MPI). A abordagem terapêutica é variada, passando por um tratamento conservador ou interventivo. Encontra-se frequentemente a MP em crianças com perturbação do espectro do autismo (PEA), discutindo-...
A Rare Case of En Bloc Endometrium Shedding
Mamede, R; Costa, C; Djokovic, DThe human endometrium is a unique tissue capable of repeated degradation, loss and self-repair in response to fluctuating levels of sex steroids, in a tightly regulated process. It takes place hundreds of times in a woman’s lifetime, manifesting as vaginal expulsion of blood mixed with cellular debris for a period of several days. The aim of this work is to present a case of en bloc endometrial desquamation in ...
Morphologic and Genetic Analysis of Synhimantus (Synhimantus) laticeps from a L...
Lopes, C; Santos-Silva, S; Nunes, C; Mendes, S; Costa, C; Brazio, E; Coutinho, T; Rodrigues, FT; Mesquita, JR; Coelho, AC; Cardoso, L; Lopes, APThe long-eared owl (Asio otus) is a medium-sized owl species that is well-distributed in almost all of the territories in Portugal. Nematodes were found in the oral cavity of a long-eared owl (A. otus) admitted to CRASSA (Wildlife Rehabilitation Centre of Santo Andre). During a physical exam and stabilization of the bird, five nematodes were collected. The worms were examined and measured under light microscopy...
