The aim of this study was to assess iodine status in pregnant women in Porto region and its association with iodine supplementation. Methods A cross-sectional study was conducted at Centro Hospitalar Universitário São João, Porto, f...
Valorization of Phenolic and Carotenoid Compounds of Sechium edule (Jacq. Swart...
Vieira, EF; Souza, S; Moreira, MM; Cruz, R; da Silva, AB; Casal, S; Delerue Matos, CChayote leaves are known for culinary and traditional medicine applications. This work intended to recover carotenoids and phenolic compounds from chayote leaves using the ultrasound-assisted extraction (UAE). A Box–Behnken design was employed to investigate the impact of extraction time, temperature, and ultrasonic power on the recovery of total carotenoids, total phenolic compounds, and antioxidant activities...
Chayote (Sechium edule): A review of nutritional composition, bioactivities and...
Vieira, EF; Pinho, Olívia; Ferreira, IMPLVO; Delerue Matos, CChayote (Sechium edule) has gained widespread consuming acceptance and recognized by its nutritional and bio-functional properties. The present review surveys and describes the current findings about the nutritional, phytochemical and pharmacological properties of chayote and identifies opportunities for further research. It also discusses chayote's versatile utility in nutrition, as a functional ingredient in ...
Polycyclic aromatic hydrocarbons in primary school environments: Levels and pot...
Oliveira, M; Klara Slezakova; Madureira, J; Fernandes, ED; Delerue Matos, C; Morais, S; Maria do Carmo PereiraAlthough polycyclic aromatic hydrocarbons (PAHs) are priority air pollutants that strongly affect human health, information concerning the indoor exposures is still limited. This study characterized PAH levels in primary schools and evaluated risk for the respective students (aged 8-10 years) in comparison with school personnel. During January-April 2014, eighteen particulate-bound (PM2.5) PAHs (16 USEPA priori...
Firefighter's occupational exposure to PM2.5 and Polycyclic Aromatic Hydrocarbons
Oliveira, M; Klara Slezakova; Fernandes, A; Vaz, JA; Delerue Matos, C; Morais, S; Maria do Carmo PereiraThis study collected the personal PM2.5 air fraction in fifteen healthy and no-smoking firefighters during their normal shift inside four Portuguese fire stations. Indoor PM2.5 levels varied between 0.05 to 1.04 mu g/m(3). Polycyclic Aromatic Hydrocarbons (PAHs) are known for their ubiquity and toxicity, being some of them classified as carcinogenic and possible carcinogens to humans. Firefighters' personal PM2...
Assessment of gaseous pollutants in a preschool environment
Oliveira, M; Klara Slezakova; Delerue Matos, C; Morais, S; Maria do Carmo PereiraThis work characterizes levels of main air pollutants in a preschool environment (3-5-years old children). The main gaseous pollutants, namely Total Volatile Organic Compounds (TVOCs), formaldehyde, carbon monoxide (CO), carbon dioxide (CO2), and ozone (O-3) were concurrently measured indoors and outdoors for 22 consecutive days at a preschool situated in urban zone of Chaves in north of Portugal. The results s...
Characterization of indoor air pollution in a portuguese pre-school
Oliveira, M; Delerue Matos, C; Morais, S; Klara Slezakova; Maria do Carmo PereiraThe objective of this work was to investigate the levels of some relevant indoor pollutants (total volatile organic compoundsTVOCs, ozoneO<inf>3</inf>, carbon dioxideCO<inf>2</inf>, carbon monoxideCO, formaldehydeHCHO, total suspended particulate matterTSP) with emphasis on Polycyclic Aromatic Hydrocarbons (PAHs) in a pre-school environment and to assess the risks associated with the exposure to carcinogenic PA...
Commercial squids: Characterization, assessment of potential health benefits/ri...
Torrinha, A; Gomes, F; Oliveira, M; Cruz, R; Mendes, E; Delerue Matos, C; Casal, S; Motais, SThe most consumed squid species worldwide were characterized regarding their concentrations of minerals, fatty acids, cholesterol and vitamin E. Interspecific comparisons were assessed among species and geographical origin. The health benefits derived from squid consumption were assessed based on daily minerals intake and on nutritional lipid quality indexes. Squids contribute significantly to daily intake of s...
Exposure to polycyclic aromatic hydrocarbons and the associated health risks in...
Oliveira, M; Klara Slezakova; Delerue Matos, C; Maria do Carmo Pereira; Morais, SUp to this date, numerous studies have associated exposure to PAHs with various health problems. The increasing awareness of the health hazards posed by PAHs present in indoor air has led to many preventive and restorative indoor air quality programs being implemented worldwide. Typically, the health concerns of PAHs are focused on their potential cytotoxicity, mutagenicity, and carcinogenicity in humans. Where...
Occupational exposure to polycyclic aromatic hydrocarbons
Klara Slezakova; Oliveira, M; Delerue Matos, C; Morais, S; do Carmo Pereiral, MThe quality of indoor and outdoor air is one of the most discussed topics nowadays, as it is an important parameter influencing human health. Exposure to various health-hazardous atmospheric pollutants may result in various adverse health effects. To understand the relationship between air quality and health, it is important to study pollutants that have the most hazardous effects on human health. In that regar...
