Butylone effects on swimming behaviour and biochemical parameters on Daphnia magna
Carvalho, Ana Rita; Gonçalves, Virgínia M. F.; Tiritan, Maria Elizabeth; Carrola, João Soares; Castro, Bruno; Ribeiro, Ana Rita Lado RibeiroBackground: Psychoactive substances (e.g. cathinones) may be detected in environmental samples, posing risks to wildlife and human health [1, 2]. Butylone (BTL) is a chiral synthetic cathinone available as a racemate [1]. Nevertheless, both human metabolism and biodegradation at wastewater treatment plants may be enantioselective causing changes in its enantiomeric fraction (EF) [2]. Therefore, enantiomers may ...
Exploring the swimming behavior of Daphnia magna exposed to a mixture of five p...
Pereira, Ana Sofia; Carvalho, Ana Rita; Couto, Cristina; Carrola, João Soares; Castro, Bruno; Ribeiro, CláudiaBackground: Psychoactive substances (PAS) are commonly found in freshwater ecosystems increasing concern about the potential negative impacts on non-target organisms, such as aquatic invertebrates [1]. Indeed, the environmental occurrence of amphetamine (AMP), and recreative drugs as 3,4-methylenedioxymethamphetamine (MDMA), 3,4-methylenedioxyamphetamine (MDA), and synthetic cathinones as butylone (BTL) and 3,4...

Psychological suffering in informal caregivers: the reality in Alto Minho
Castro, Bruno; Lopez, Ana; Dias, Sónia; Xavier, MiguelIntroduction: The increase in average life expectancy, associated with the decrease in birth rates, led to an aging population with an overburden of health services. A large proportion of health care is provided by informal caregivers and this study aims to assess the degree of psychological distress associated with caring. Material and methods: An observational, cross-sectional study was carried out with 131 i...
