In this study, the antioxidant properties of Viviparus contectus (V. contectus) extract were evaluated for various radical scavenging activities, ferric reducing antioxidant power (FRAP), ABTS radical scavenging activity and oxygen radical absorbance capacity (ORAC). In addition, inhibition effect of the V. Read More

A phenomenon of switching of the parasite in the food chain to an accidental host is commonly observed in nature. However, there is little available data concerning the morphological descriptions of parasites that passively get into the atypical hosts and are capable, at least to some degree, of somatic growth and development of reproductive structures. A morphological survey of Diplodiscus subclavatus (Pallas, 1760) adults isolated from a digestive tract of an accidental host, Viviparus contectus (Millet, 1813), was carried out. Read More

Experimental measurements of the (18)O/(16)O isotope fractionation between the biogenic aragonite of Viviparus contectus (Gastropoda) and its host freshwater were undertaken to generate a species-specific thermometry equation. The temperature dependence of the fractionation factor and the relationship between Deltadelta(18)O (delta(18)O(carb.) - delta(18)O(water)) and temperature were calculated from specimens maintained under laboratory and field (collection and cage) conditions.

Toxic bloom-forming cyanobacteria can cause animal death and adversely affect human health. Blooms may contain microcystins (MCs), cyanobacterial heptapeptide hepatotoxins and other peptides such as anabaenopeptins and anabaenopeptilides. MCs have been shown to occur in various aquatic organisms including mussels, water snails, crustaceans and fish. Read More

A variety of common histological stains was used, along with the Golgi and Colognier silver impregnation methods and electron microscopy, to perform a comparative study of the morphological characteristics of receptor and nerve cells and their interactions in the nervous system of the wall of the mantle cavity and mantle derivatives - gills, siphon, and osphradia - of the marine prosobranch gastropod mollusks Buccinum undatum and Littorina littorea. The results are discussed along with our own previously obtained data on the organization of the osphradial sensory organs and the afferent elements of the mantle cavity wall in other prosobranch mollusks - the terrestrial Pomatia elegans and the freshwater Viviparus contectus and Pomacea paludosa. Using the nervous system of the complex of mantle organs of prosobranch mollusks as examples, the structural features and evolutionary trends of the afferent part of the visceral nervous system of gastropods are discussed.
