Polyunsaturated fatty acids (PUFA) and eicosapentaenoic acid (EPA) are essential for the health of aquaculture organisms and human beings. A total of 9 species of diatoms were screened and two strains of Skeletonema menzelii were selected for further study due to their high growth rates, PUFA and EPA contents. The culture conditions for the yield of(More)
The port city of Yantai, in Shandong province China is located on Sishili Bay in the northern Yellow Sea. Intense human activity associated with urban sewage discharge, as well as industrial and maritime activities, have stressed the Sishili Bay coastal ecosystem with anthropogenic pollution. The aim of this study was to measure the levels of heavy metal in(More)
Proteus mirabilis is an important pathogen that is usually found in complicated urinary tracts infection. It possesses a metalloprotease, ZapA, that acts as a virulence factor. The gene encoding ZapA was cloned from P. mirabilis Pm7—a strain isolated from marine environments—and conditionally expressed in Escherichia coli. Zn2+ and Co2+ exhibited an(More)
MiR-31 is a critical regulator of gene expression in many pathogenic processes in vertebrates. In this study, we identified p105 as a novel target of miR-31 in Apostichopus japonicus and investigated their regulatory roles in vitro and in vivo. The negative expression profiles between miR-31 and Ajp105 were detected in both LPS-exposed primary coelomocytes(More)
To elucidate the effects of scallop mariculture on the macrobenthic community in a moderate energy system, bimonthly samples from four transects along a distance gradient in Sishili Bay, the northern Yellow Sea of China, were investigated. Differences in macrobenthic community structure along the distance gradient were evaluated using univariate and(More)
The JAK/STAT signal transduction pathway plays a critical role in host defense against bacterial infections. In the present study, we firstly cloned the full-length cDNAs of three molecules in JAK/STAT cascade, STAT5, FOXP and SOCS2, from sea cucumber Apostichopus japonicus (denoted as AjSTAT5, AjFOXP, AjSOCS2, respectively) and investigated their immune(More)
In the present study, the effects of an environmental friendly natural reagent coumarin, on the growth and potential virulence factors, as well as its ability to interfere the infection of Vibrio splendidus (Vs), were determined. Coumarin showed no effects on the maximal growth of Vs, and biofilm formation of Vs, while it significantly decreased protease(More)
The present paper reports two new species of Glyphocrangon (Crustacea, Caridea, Glyphocrangonidae) collected respectively from the East China Sea and the Philippines. G. singularis sp. nov., from the East China Sea, is similar to G. fimbriata Komai & Takeuchi, 1994 with the presence of fringe of setae on dactyl of the third to fifth pereopods, but differs(More)
