Characterization of ethoxyresorufin O-deethylase activity (EROD) in oyster Crassostrea brasiliana

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2017
Cytochrome P450 family 1 (CYP1) is involved in polycyclic aromatic hydrocarbons (PAHs) biotransformation. PAHs can induce CYP1 protein expression and enzyme activity, the latter being usually quantified as 7-ethoxyresorufin O-deethylase activity (EROD).

Analysis of transcriptional responses of normalizing genes on Crassostrea brasiliana under different experimental conditions

Environmental Toxicology and Chemistry, 2017
Abstract   Bivalves show remarkable plasticity to environmental changes and have been proposed as sentinel organisms in biomonitoring. Studies related to transcriptional analysis using quantitative real-time polymerase chain reaction (qRT-PCR) in these organisms have notably increased, imposing a need

Concentration of polycyclic aromatic hydrocarbons (PAHs) and histological changes in Anomalocardia brasiliana and Crassostrea rhizophorae from Pernambuco, Brazil after the 2019 oil spill

Marine Pollution Bulletin, 2023
The present study aimed to analyze the concentrations of polycyclic aromatic hydrocarbons (PAHs) in populations of the shellfish Anomalocardia brasiliana and oysters Crassostrea rhizophorae three years after the 2019 oil spill, as well as evaluate histopathological changes on the gill tissues of the bivalves. Individuals of both species were sampled at

Pathogenic bacteria associated with oysters (Crassostrea brasiliana) and estuarine water along the south coast of Brazil

International Journal of Environmental Health Research, 2007
Oysters and estuarine water samples were collected monthly, from June 1998 to March 1999, in the Cananéia estuary, on the south coast of São Paulo, Brazil, and analyzed for bacterial hazards with and without depuration in filtered estuarine water.

Thiol oxidation of hemolymph proteins in oysters Crassostrea brasiliana as markers of oxidative damage induced by urban sewage exposure

Environmental Toxicology and Chemistry, 2016
Abstract   Urban sewage is a concerning issue worldwide, threatening both wildlife and human health. The present study investigated protein oxidation in mangrove oysters (Crassostrea brasiliana) exposed to seawater from Balneário Camboriú, an important tourist destination in Brazil that is affected by

Biochemical biomarkers and hydrocarbons concentrations in the mangrove oyster Crassostrea brasiliana following exposure to diesel fuel water-accommodated fraction

Aquatic Toxicology, 2011
Understanding the toxic mechanisms by which organisms cope to environmental stressful conditions is a fundamental question for ecotoxicology. In this study, we evaluated biochemical responses and hydrocarbons bioaccumulation of the mangrove oyster Crassostrea brasiliana exposed for 96 h to four sublethal concentrations of diesel fuel water-accommodated

Growth and allometry of the larval shell of the Brazilian oysterCrassostrea brasiliana(Lamarck, 1819) (Bivalvia: Ostreidae)

Ophelia, 2000
Abstract The Brazilian oyster Crassostrea brasiliana (Lamarck, 1819) is a dominant estuarine benthic species of the Parana littoral (Southern Brazil) and an important economic fisheries resource. In this paper we describe its larval cycle, from fertilization to metamorphosis, in controlled conditions of temperature, food and water quality. Growth rates

Suppressive subtractive hybridization libraries prepared from the digestive gland of the oyster Crassostrea brasiliana exposed to a diesel fuel water-accommodated fraction

Environmental Toxicology and Chemistry, 2012
Abstract Diesel fuel can cause adverse effects in marine invertebrates by mechanisms that are not clearly understood. The authors used suppressive subtractive hybridization to identify genes up- and downregulated in Crassostrea brasiliana exposed to diesel fuel.

Temporal and spatial variability in Zn, Cr, Cd and Fe concentrations in oyster tissues(crassostrea brasiliana lamarck, 1819)from Sepetiba Bay, Brazil

Environmental Technology Letters, 1986
Abstract Temporal and spatial variability in metal concentrations (Zn, Cr, Cd and Fe) in soft tissues of the oyster C. brasiliana from Sepetiba Bay and Ribeira Bay were determined for three different periods.Significant spacial differences were observed for Zn and Cd but no temporal variations were detected.
