Should apple snail Pomacea canaliculata (Caenogastropoda, Ampullariidae) be used as bioindicator for BDE-209?
(Springer Heidelberg, 2014-01)
Apple snail Pomacea canaliculata has been reported to accumulate polybrominated diphenyl ethers (PBDEs) and was recently proposed as PBDE bioindicator. This work investigates the ability of P. canaliculata to accumulate ...
Uptake, metabolism and sub-lethal effects of BDE-47 in two estuarine invertebrates with different trophic positions
(Elsevier, 2016-06)
Two microcosm types -sediment-biota and biota-biota- were constructed to simulate different pathways of BDE-47 uptake, metabolism and oxidative stress effects in two key estuarine invertebrates (polychaete Laeonereis acuta ...
Exposure to BDE-153 induces autophagy in HepG2 cells
(2017-08-01)
Autophagy is a pro-survival process that occurs under stressful “life-threatening” conditions. This process clears the cells of damaged organelles, long-lived proteins, and/or misfolded proteins. Under stressful conditions, ...
Éteres difenílicos polibromados (PBDE) em sedimentos do Lago Paranoá, DF
(2017-08-18)
Esse estudo buscou investigar a ocorrência de PBDE em sedimentos do Lago Paranoá - DF. Para tanto, um método analítico foi desenvolvido, validado e aplicado para determinação de nove congêneres (BDE-28, BDE-47, BDE-66, ...
Mitochondrial damage and apoptosis: Key features in BDE-153-induced hepatotoxicity
(2018-08-01)
Brominated flame retardants are used in consumer goods to increase product resistance to fire and/or high temperatures. Polybrominated diphenyl ethers (PBDEs) are the most commonly employed class of brominated flame ...
Exposure to decabromodiphenyl ether (BDE-209) produces mitochondrial dysfunction in rat liver and cell death
(Taylor & Francis Inc, 2017-01-01)
Polybrominated diphenyl ethers (PBDE) are ubiquitous environmental pollutants. Exposure to these chemicals has been associated with developmental neurotoxicity, endocrine dysfunctions, reproductive disorders, and hepatotoxicity. ...
Estudo Comparativo de Métricas de Pontuação para Aprendizagem Estrutural de Redes Bayesianas
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2006-08-30)
Bayesian networks are powerful tools as they represent probability distributions as graphs. They work with uncertainties of real systems. Since last decade there is a special interest in learning network structures from ...
