Enhancing the detection of Dinophysis spp. using electrochemical genosensors
Pereira, Eduarda; Silva, Aurora; Morais, Stephanie L.; Costa-Rama, Estefanía; Moreira, Patrícia R.; Fraga-Corral, M.; Torrado, Ana M.Background: Harmful algal blooms (HABs) pose a significant threat to the environment and public health. These blooms are defined by an accumulation of microscopic algae in water, and they can occur in lakes, rivers, estuaries, or coastal areas. Factors like the unregulated runoff of agricultural and industrial wastes into the aquatic environment [1] are believed to have transformed these ecosystems into favorab...
Chronic toxicity of valproic acid in Daphnia magna
Machado, Beatriz; Prudêncio, Cristina; Ferraz, Ricardo; Barros, PiedadeBackground: Environmental exposure to pharmaceuticals, have negative effects on the health of ecosystems and humans and numerous pharmaceuticals have been identified on surface waters all around the world [1]. After administration, medicines are absorbed, metabolized, and excreted to the sewer system, but many are refractory to the traditional wastewater treatment and become widely distributed in freshwater riv...
Ecotoxicity of valproic acid in Lemna minor
Machado, Beatriz; Prudêncio, Cristina; Ferraz, Ricardo; Barros, PiedadeBackground: The water pollution represents one of the most serious ecological challenges [1]. Over the last years the use and consumption of pharmaceuticals has increased, and this is reflected in the rise of water contamination. Many drugs cannot be efficiently removed by wastewater treatment and ended up being released into the aquatic environment [2]. Valproic acid is an anticonvulsive and mood stabilizer m...

Is it possible to prevent Harmful Algal Blooms? An electrochemical genosensor t...
Pereira, Eduarda; Silva, Aurora; Morais, Stephanie L.; Costa-Rama, Estefanía; Moreira, Patrícia R.; Fraga-Corral, M.; Torrado, Ana M.Harmful Algal Blooms (HABs) are a very common phenomenon in the last few years that results from the accumulation of microalgae, such as dinoflagellates of the Dinophysis genus. Hence, the development of analytical technologies capable of detecting these microorganisms and thereby avoiding environmental and public health crisis, has become a major priority. Biosensors have been gaining recognition lately given ...

Detecting toxic dinoflagellates (Dinophysis spp.) using electrochemical genosen...
Pereira, Eduarda; Barros, Piedade; Cruz, Agostinho; Santos, MarleneAquatic environments are important economic and ecological sources for human activities (e.g. fisheries, tourism, agriculture and aquaculture). However, the increase in those practices has, over the years, compromised the integrity of these ecosystems. Runoffs of terrestrial nutrients (from, for example, agricultural and industrial waste) and higher surface temperatures are believed to have transformed these ec...
Toxic dinoflagellates (dinophysis spp.) detection by genosensors and molecular ...
Pereira, Eduarda; Barros, Piedade; Cruz, Agostinho; Santos, MarleneOver the years, the marine ecosystems integrity has been compromised, due to multiple factors that disrupt the natural balance of phytoplankton. Factors such as the unregulated runoff of agricultural and industrial wastes into the aquatic environment and higher surface temperatures are believed to have transformed these ecosystems into favorable habitats for algae growth and proliferation. As a result, multiple...

Quintela Vieira, Ana Filipa; Cruz, Agostinho; Oliveira, Ana; Pinho, Cláudia; Prudêncio, Cristina; Vieira, Mónica; Barros, Piedade; Ferraz, RicardoUma equipa multidisciplinar do CISA-ESS | P. PORTO em colaboração com o CI|IPOP dedicou-se ao estudo do potencial anti-tumoral de novos compostos em tumores de grande incidência em Portugal: cancro da mama e da próstata. O potencial anti-tumoral de extratos de plantas e compostos sintéticos foi avaliado em linhas celulares de cancro da próstata e da mama, sendo a resposta terapêutica prevista através de amostra...
