Microanatomical organization of hepatic stroma of the brown trout, Salmo trutta fario (Teleostei, Salmonidae): A qualitative and quantitative approach
Rocha E, Monteiro R, Pereira C
J Morphol . 2018 Jun; 223(1):1-11. PMID: 29865308
Despite the absence of lobulation, light microscopy of serial sections of the liver of brown trout, Salmo trutta fario, reveals that the stromal elements are spatially organized as venous-biliary-arteriolar tracts...

Frequency of micronuclei and of other nuclear abnormalities in erythrocytes of the grey mullet from the Mondego, Douro and Ave estuaries--Portugal
Carrola J, Santos N, Rocha M, Fontainhas-Fernandes A, Pardal M, Monteiro R, et al.
Environ Sci Pollut Res Int . 2014 Jan; 21(9):6057-68. PMID: 24469770
Fish are bioindicators of water pollution, and an increased rate of their erythrocyte nuclear morphological abnormalities (ENMAs)-and particularly of erythrocyte micronuclei (EMN)-is used as a genotoxicity biomarker. Despite the potential...

Testing the effects of ethinylestradiol and of an environmentally relevant mixture of xenoestrogens as found in the Douro River (Portugal) on the maturation of fish gonads--a stereological study using the zebrafish (Danio rerio) as model
Silva P, Rocha M, Cruzeiro C, Malhao F, Reis B, Urbatzka R, et al.
Aquat Toxicol . 2012 Aug; 124-125:1-10. PMID: 22885794
In natural environments fish populations are exposed to many potential xenoestrogens, whereby understanding the impacts of mixtures continue to be of great interest. The main objective of this study was,...
6.
A stereological study of the volume-weighted volume and of the relative volume of the nucleus of normal and preneoplastic hepatocytes in a trout model of hepatocarcinogenesis
Santos M, Monteiro R, Rocha E
Exp Toxicol Pathol . 2012 Aug; 65(5):623-30. PMID: 22862953
The fish liver has been the main subject of the biomonitoring and laboratory studies dealing with environmental carcinogenesis. The foci of cellular alterations are accepted pre-neoplastic hepatic lesions, and histopathology...

The toxicity potential of pharmaceuticals found in the Douro River estuary (Portugal): evaluation of impacts on fish liver, by histopathology, stereology, vitellogenin and CYP1A immunohistochemistry, after sub-acute exposures of the zebrafish model
Madureira T, Rocha M, Cruzeiro C, Rodrigues I, Monteiro R, Rocha E
Environ Toxicol Pharmacol . 2012 Mar; 34(1):34-45. PMID: 22445869
Qualitative and quantitative approaches were tested to assess zebrafish liver effects after sub-acute exposures of certain pharmaceuticals. Carbamazepine, fenofibric acid, propranolol, sulfamethoxazole and trimethoprim were tested individually and in mixtures,...
8.
The use of design-based stereology to evaluate volumes and numbers in the liver: a review with practical guidelines
Marcos R, Monteiro R, Rocha E
J Anat . 2012 Feb; 220(4):303-17. PMID: 22296163
Stereology offers a number of tools for the analysis of sections in microscopy (which usually provide only two-dimensional information) for the purpose of estimating geometric quantities, such as volume, surface...

The toxicity potential of pharmaceuticals found in the Douro River estuary (Portugal): assessing impacts on gonadal maturation with a histopathological and stereological study of zebrafish ovary and testis after sub-acute exposures
Madureira T, Rocha M, Cruzeiro C, Galante M, Monteiro R, Rocha E
Aquat Toxicol . 2011 Jul; 105(3-4):292-9. PMID: 21781654
Concerns associated with pharmaceuticals in aquatic systems demand the establishment of links between xenobiotics and their respective concentrations and impacts on aquatic organisms. Herein, effects of non-steroidal pharmaceuticals in the...

In vitro exposure of Nile tilapia (Oreochromis niloticus) testis to estrogenic endocrine disrupting chemicals: mRNA expression of genes encoding steroidogenic enzymes
Ribeiro C, Urbatzka R, Castro L, Carrola J, Fontainhas-Fernandes A, Monteiro R, et al.
Toxicol Mech Methods . 2011 Jul; 22(1):47-53. PMID: 21721901
Many environmental pollutants can exert adverse effects on exposed organisms, including fish, leading to disruption of the endocrine system. Enzymes involved in the sex steroid biosynthesis are potential targets for...
