Diuron determines Saccharomyces cerevisiae UE-ME3 survival at beginning of expo...
Tenda, H; Alves-Pereira, I; Ferreira, RuiThe diuron is an herbicide used on autumn-winter crops, due to its ability to block the chloroplast electron chain at level of photosystem II. Furthermore, diuron can also exert toxic effects on heterotrophic beings, blocking the respiratory chain and ROS generating. Despite the progressive suppression of diuron application by Directive 200/60/CE, groundwater contamination will still persist. Therefore the main...
Fenilureias diminuem a actividade enzimática glucose-6-P desidrogenase de Sacch...
Tenda, H; Candeias, M; Pinheiro, M; Alves-Pereira, I; Ferreira, ROs resultados mostram que as duas fenilureias diminuem significativamente esta actividade catalítica em células em fase replicativa e senescente, expostas a níveis superiores a 25 µM, sendo esse efeito superior na presença de diurão, facto que evidencia uma maior toxicidade deste composto, por bloqueio energético e da divisão celular. Contudo observou-se um incremento significativo desta actividade enzimática e...

Tenda, H; Alves-Pereira, I; Ferreira, RThe diuron, 3-(3,4-dichlorophenyl)-1,1-dimethylurea, is an herbicide used on autumn-winter crops, due to its ability to block the chloroplast electron chain at level of photosystem II. Although most of the living beings that contact with diuron are heterotrophic, this shows high toxicity for them, since it can also block the respiratory chain, behaving as ROS inductor. This herbicide is classified as POPs, bec...
