Introduction/purpose: In this study, we investigated the possibility of removing organophosphorus pesticide malathion from water using a new adsorbent based on biowaste river shell shards Anodonta Sinadonta woodiane family, material that accumulates in large quantities as waste banks rivers. Two adsorbents were tested - mechanically comminuted shells (MRM) and mechanosynthetic hydroxyapatite (R...

The mammalian target of rapamycin (mTOR) has been shown to play a central role in regulating cell growth and metabolism. However, little is known about the function mTOR nutrient metabolism bivalve mollusks. In this study, regulation was investigated Sinonovacula constricta. First, activation assayed after starvation refeeding. Afterwards, using an activator (MHY1485) or inhibitor (rapamycin) m...

To complete their life cycle, freshwater mussels of the order Unionida depend on fishes as hosts for obligatory parasitic larval phase, glochidium. Here we report first documentation gobioid glochidia unionid in wild Italy and southern Europe (outside Danube drainage area). We also examined pattern attached glochidia. A recent review reported 326 fish species suitable unionids, but only eight (...

Seasonal changes of microcystin (MC) bioaccumulation in three freshwater Unionid bivalves, Anodonta woodiana, Cristaria plicata, and Unio douglasiae, were investigated in the hypereutrophic Lake Suwa. Total MC concentrations (MC-RR and -LR) as determined by reverse-phase high-performance liquid chromatography were at high levels in the hepatopancreas of C. plicata and U. douglasiae, with maxima...

Parasites can negatively affect hosts at individual, population, and species-level scales. However, the link between individual- population-level impacts is often poorly understood. In particular, response to parasitism may alter wider ecosystem dynamics if animals with engineering capabilities are infected. Here, we examine effects of on a freshwater engineer, unionid mussel Anodonta anatina, ...

Manganese in the tissues of normal animals may be regarded as a rare element. In traces it is known to be present in a number of marine animals, as was shown by Pichard.’ Hoppe-Seyler2 is authority for the statement that it is not infrequently present in human blood and in the liver: but it is neither constant in its occurrence nor significant in amount. Among the lower animals there is at leas...

Surficial (oxic) sediments, overlying water, and specimens of the freshwater bivalve Anodonta grandis were collected by divers at 11 littoral lacustrine sites located along a geochemical gradient of pH, [Cd], Dl, and [Z n in an area influenced by mining and smelting activities. The molluscs were dissected (gills; 1 hepatopancreas; remaining tissues) and analyzed for Cd, Cu, Zn, and metallothion...
