Oxidative stress in Perna perna and other bivalves as indicators of environmental stress in the Brazilian marine environment: antioxidants, lipid peroxidation and DNA damage.
Eduardo Alves de Almeida,Afonso Celso Dias Bainy,Ana Paula de Melo Loureiro,Glaucia Regina Martinez,Sayuri Miyamoto,Janice Onuki,Lívea Fujita Barbosa,Camila Carrião Machado Garcia,Fernanda M. Prado,Graziella E. Ronsein,Carlos A. O. Sigolo,Cláudia Barbosa Brochini,Ana Maria Gracioso Martins,Marisa Helena Gennari de Medeiros,Paolo Di Mascio +14 more
TL;DR: This review summarizes the data obtained in some studies carried out in bivalves from the Brazilian coast subjected to different stress conditions, including the exposure to different contaminants in the laboratory and in the field.
Journal ArticleDOI

TL;DR: This work addresses the importance of isotope labeling associated with mass spectrometry technique for biomolecule damage studies and provides the first evidence of the occurrence of 1,N(2)-epsilondGuo as a basal endogenous lesion and may be utilized to better assess the biological consequences of etheno DNA damage under normal and pathological conditions.
Journal ArticleDOI
Oxidative stress in the mussel Mytella guyanensis from polluted mangroves on Santa Catarina Island, Brazil.
M. A. Torres,Camila Pires Testa,Catia Gáspari,Mariana Beatriz Masutti,Clarice Maria Neves Panitz,Rozangela Curi-Pedrosa,Eduardo Alves de Almeida,Paolo Di Mascio,Danilo Wilhelm Filho +8 more
TL;DR: Digestive glands of the mangrove mussel Mytella guyanensis, collected at one non-polluted site and two polluted sites, were analysed for different antioxidant defenses, lipid peroxidation and DNA damage.
Journal ArticleDOI
Protective effect of phospholipid hydroperoxide glutathione peroxidase (PHGPx) against lipid peroxidation in mussels Perna perna exposed to different metals
Eduardo Alves de Almeida,Sayuri Miyamoto,Afonso Celso Dias Bainy,Marisa Helena Gennari de Medeiros,Paolo Di Mascio +4 more
TL;DR: Positive correlations were observed between the enzyme phospholipid hydroperoxide glutathione peroxidase (PHGPx) and malonaldehyde (MDA) levels after Fe and Cu exposure, indicating a protective role of PHGPx against lipid peroxidation, and suggesting the use of this enzyme as a new potential biomarker of toxicity associated with contaminant exposure in mussels.
Journal ArticleDOI
Oxidative stress in digestive gland and gill of the brown mussel (Perna perna) exposed to air and re-submersed
Eduardo Alves de Almeida,Afonso Celso Dias Bainy,Alcir Luiz Dafre,Osmar F. Gomes,Marisa Helena Gennari de Medeiros,Paolo Di Mascio +5 more
TL;DR: The DNA and lipid oxidative damage observed after aerial exposure indicates that mussels face an oxidative challenge, and are able to counteract such an “insult” as values of lipid peroxidation and DNA damage returned to control values after 3 h re-submersion.
