The Pacific cupped oyster, Crassostrea gigas, is one of the major aquacultural shellfish species that has been introduced to Europe and America from its native source in the West Pacific. In Taiwan, the cultivated cupped oysters along the west coast have been identified as C. gigas for over centuries; however, several molecular phylogenetic studies have cast doubt upon the existence of this spe...

Oysters are economically and ecologically important bivalves, with its calcareous shell and delicious meat. The shell composition is a blend of inorganic crystals and shell proteins that form an organic matrix which protects the soft inner tissue of the oyster. The objective of the study was to compare the composition of organic matrix proteins (OMP) of two phylogenetically related species: the...

Oysters, with high levels of phenotypic plasticity and wide geographic distribution, are a challenging group for taxonomists and phylogenetics. Our study is intended to generate new EST-SNP markers and to evaluate their potential for cross-species utilization in phylogenetic study of the genus Crassostrea. In the study, 57 novel SNPs were developed from an EST database of C. gigas by the HRM (h...

At present, over 300 species of marine alien Mollusca are reported from the European waters (Streftaris et al. 2005; Zenetos et al. 2010). However, only three alien polyplacophoran have been recorded: Chaetopleura angulata (Spengler, 1797), Acanthopleura gemmata (Blainville, 1825) and Chiton hululensis (E. A. Smith, 1903); the latter is considered as “questionable” (Zenetos et al. 2010). These ...

Ferulago angulata leaf hexane extract (FALHE) was found to be a potent inducer of MCF7 cell apoptosis. The aims of the present study were to investigate the in vivo chemopreventive effect of FALHE in rats, to identify the contributing anticancer compound in FALHE and to determine its potential mechanism of action against MCF7 cells. Thirty rats harboring LA7-induced breast tumors were divided i...

In order to determine if ostreid herpesvirus 1 (OsHV-1) can be vertically transmitted, 9 full-sib families of the Portuguese oyster Crassostrea angulata were produced using a factorial mating design with 3 males and 3 females. The parents were survivors from an OsHV-1 mortality outbreak. OsHV-1 DNA was not detected by conventional PCR in the mantle of parents, gametes or 3day-old larvae. Howeve...

The article describes a new rove beetle species, Thiasophila szujeckii sp. n., in southeastern Poland. This new species is associated exclusively with Formica truncorum. The authors describe its sexual dimorphism of habitus, structure of antennae, eighth abdominal tergite and eighth sternite. T. szujeckii sp. n. shares most morphological features with T. angulata and T. lohsei known in Europe. ...

conclusions ferulago angulata extract, because of its antioxidant activities, is probably capable of removing free radicals and oxidant substances from brain and thus it can improve behavioral disorders in brain hypoperfusion ischemia model. results it was found that the administration of 400 mg/kg hydroalcoholic extract of f. angulate for two weeks after brain hypoperfusion ischemia increased ...
