Histological development of the digestive tract and specific activities of three digestive enzymes (trypsin, alkaline phosphatase, and pepsin) were studied in rock bream Oplegnathus fasciatus from hatching to 50 days after hatching (DAH). At hatching, the digestive tract appeared as an undifferentiated straight tube and differentiated into the buccopharynx,(More)
Specification of primordial germ cells during early embryogenesis is a critical biological issue in reproduction and development. Yet, little is known in marine economic fish species. Vasa, a component of germ plasm, is the most-documented germ cell marker in teleosts. We isolated a full-length vasa cDNA (Smvas) from turbot (Scophthalmus maximus), a marine(More)
The present study was to evaluate the effects of six antioxidants on frozen-thawed sperm motility, viability, membrane integrity and mitochondrial function in red seabream (Pagrus major) by computer-assisted sperm analysis system and flow cytometry, respectively. All the parameters tested in this study were determined using one-way ANOVA and identified(More)
No-tillage (NT) has revolutionized agricultural systems because it has potential benefits including soil conservation and reduced production costs though saving in fuel, equipment, and labor. Soil quality is of great importance in determining the sustainability of land management systems, and soil microbial properties are becoming increasingly used to(More)
The current paper investigated the removal of the azo dye Orange II from water using advanced oxidation processes based on sulfate radicals. The cobalt oxide catalyst immobilized on graphene oxide (GO) can activate peroxymonosulfate (PMS) for the degradation of Orange II in water. The Co(3)O(4)/GO catalyst system was characterized via X-ray diffraction,(More)
Nitrification of human urine performed for its stabilization, and culture of Spirulina platensis in the nitrified human urine were investigated for nutrient recovery. With daily adjusting to pH 8 and keeping high dissolved oxygen concentration, mean 95.0% of NH(4)-N in human urine can be finally stabilized and oxidized to NO(3)-N. Furthermore, this(More)
A magnetically separable photocatalyst TiO(2)/SiO(2)/NiFe(2)O(4) (TSN) nanosphere with egg-like structure was prepared by a unique process that combined a liquid catalytic phase transformation method, reverse micelle technique and chemical precipitation means. The prepared photocatalyst shows high photocatalytic activity for the degradation of methyl orange(More)
We characterized the expression patterns of pepsinogen A (tPGA) and pepsinogen C (tPGC) in turbot (Scophthalmus maximus). Quantitative expression analysis showed that tPGC was preferentially expressed in early developmental stages, and that the tPGA mRNA expression level was higher in adult fish. Full-length cDNA constructs of tPGA and tPGC were 1307 bp(More)
Ballast water exotic discharge has been identified as a leading vector for marine species invasion. Here immobilized TiO2 photocatalysis is introduced to improve the performance of intense pulsed light. For intense pulsed light/TiO2 photocatalysis, a typical inactivation of 99.89±0.46% can be achieved under treatment condition of 1.78 L min(-1) flow rate,(More)
A dehydrogenation anode is reported for hydrocarbon proton conducting solid oxide fuel cells (SOFCs). A Cu-Cr(2)O(3) nanocomposite is obtained from CuCrO(2) nanoparticles as an inexpensive, efficient, carbon deposition and sintering tolerant anode catalyst. A SOFC reactor is fabricated using a Cu-Cr(2)O(3) composite as a dehydrogenation anode and a doped(More)
