| unique extracellular matrix heparan sulfate from the bivalve nodipecten nodosus (linnaeus, 1758) safely inhibits arterial thrombosis after photochemically induced endothelial lesion. | heparin-like glycans with diverse disaccharide composition and high anticoagulant activity have been described in several families of marine mollusks. the present work focused on the structural characterization of a new heparan sulfate (hs)-like polymer isolated from the mollusk nodipecten nodosus (linnaeus, 1758) and on its anticoagulant and antithrombotic properties. total glycans were extracted from the mollusk and fractionated by ethanol precipitation. the main component (>90%) was identifie ... | 2010 | 20053999 |
| detection of a parasitic amoeba (order dactylopodida) in the female gonads of oysters in brazil. | the impacts of oocyte parasites on the reproductive success of molluscs are largely unknown. in this study, we evaluated the presence of gonad parasites in 6 species of marine bivalve molluscs native to southern brazil. cultured bivalves included the mangrove oyster crassostrea gasar (sometimes called c. brasiliana), the brown mussel perna perna, the lion's paw scallop nodipecten nodosus and the wing pearl oyster pteria hirundo. another species of mangrove oyster, c. rhizophorae, and the carib p ... | 2014 | 24991850 |
| exposure to phenanthrene and depuration: changes on gene transcription, enzymatic activity and lipid peroxidation in gill of scallops nodipecten nodosus. | understanding the mechanism of phenanthrene (phe) biotransformation and related cellular responses in bivalves can be an important tool to elucidate the risks of polycyclic aromatic hydrocarbons (pahs) to aquatic organisms. in the present study it was analyzed the transcriptional levels of 13 biotransformation genes related to cytochrome p450 (cyp), glutathione s-transferase (gst), sulfotransferase (sult), flavin-containing monooxygenase and fatty acid-binding proteins by qpcr in gill of scallop ... | 2016 | 27286572 |
| mantle margin morphogenesis in nodipecten nodosus (mollusca: bivalvia): new insights into the development and the roles of bivalve pallial folds. | despite extensive knowledge on bivalve anatomy and development, the formation and differentiation of the mantle margin and its associated organs remain largely unclear. bivalves from the family pectinidae (scallops) are particularly promising to cast some light on these issues, because they exhibit a complex mantle margin and their developmental stages are easily obtained from scallop farms. we investigated the mantle margin of the scallop nodipecten nodosus (l. 1758) during larval and postmetam ... | 2015 | 26017922 |
