Ultrastructural features of the glandular region of the stomach of Piaractus me...
Aires, Eduardo Duarte [UNESP]; Dias, E.; Orsi, A. M.Made available in DSpace on 2022-04-28T19:55:59Z (GMT). No. of bitstreams: 0 Previous issue date: 1999-04-01; The characteristics of the lining and glandular epithelial types of the wall of the stomach of pacú (Piaractus mesopotamicus Holmberg, 1887) were studied by transmission electron microscopy. Columnar mucous cells were observed in the lining epithelial surface and the glandular epithelium that invaginate...

Ecophysiological traits of highly mobile large marine predators inferred from n...
Alves, Filipe; Dromby, Morgane; Baptista, Vânia; Ferreira, R.; Correia, A. M.; Weyn, M.; Valente, R.; Froufe, E.; Rosso, M.; Sousa-Pinto, I.; Dinis, A.Nucleic acid-derived indices such as RNA/DNA ratios have been successfully applied as ecophysiological indicators to assess growth, nutritional condition and health status in marine organisms given that they provide a measure of tissue protein reserves, which is known to vary depending on changes in the environment. Yet, the use of these biochemical indices on highly mobile large predators is scarce. In this st...
Combining analytical methodologies for the identification of Aspergillus sectio...
Couto, F.; Santos, Cledir; Souza, T.; Dias, E.; Lima, Nelson; Batista, L.The use of chemical analysis of microbial components, including proteins, became an important achievement in the 80’s of the last century to the microbial identification. This led a more objective microbial identification scheme, called chemotaxonomy, and the analytical tools used in the field are mainly 1D/2D gel electrophoresis, spectrophotometry, high-performance liquid chromatography, gas chromatography, an...
Structure, growth and production of a remarkably abundant population of the com...
Souza, A. T.; Dias, E.; Campos, J.; Marques, J. C.; Martins, I.The common goby, Pomatoschistus microps, is a relevant species from estuarine food webs, playing important roles as predator of polychaetes and crustaceans and as prey for larger fishes and crustaceans. The Minho estuary (NW Portugal) is a relatively wellpreserved and productive system. To assess the population structure and production of P. microps in this estuary, monthly samples were undertaken in three diff...

Microcystin-LR activates the ERK1/2 kinases and stimulates the proliferation of...
Dias, E.; Matos, P.; Pereira, P.; Batoréu, M.C.C.; Silva, M.J.; Jordan, P.Microcystin-LR (MCLR) is a peptide produced by freshwater cyanobacteria that induces severe hepatotoxicity in humans and animals. MCLR is also a potent tumour promoter and it has been proposed that this activity is mediated by the inhibition of protein phosphatases PP1/PP2A, possibly through the activation of proto-oncogenes c-jun, c-fos and c-myc. However, the mechanisms underlying MCLR-induced tumour promotio...
Morphological and ultrastructural effects of microcystin-LR from Microcystis ae...
Alverca, E.; Andrade, M.; Dias, E.; Bento, F. Sam; Batoreu, M. C. C.; Jordan, P.; Silva, M. J.; Pereira, P.The aim of this study was to examine the toxic effects of a microcystin-LR (MCLR)-containing cyanobacteria extract on the subcellular organization of a kidney cell line (Vero-E6). Cells were exposed to different MCLR concentrations (1.3-150 mu M) for 24, 48 and 72 h and two cytotoxicity assays were performed. This information was combined with the analysis of lysosomal, mitochondrial and cytoskeleton integrity ...
