Macrophage migration inhibitory factor (MIF) is an important cytokine and plays a crucial role as a pivotal regulator of innate immunity. In this study, a MIF cDNA was identified and characterized from the pearl oyster Pinctada fucata (designated as PoMIF). The full-length of PoMIF was 1544 bp and consisted of a 5'-untranslated region (UTR) of 45 bp, a… (More)
In this research, catalytic steam reforming of acetic acid derived from the aqueous portion of bio-oil for hydrogen production was investigated using different Ni/ATC (Attapulgite Clay) catalysts prepared by precipitation, impregnation and mechanical blending methods. The fresh and reduced catalysts were characterized by XRD, N 2 adsorption–desorption, TEM… (More)
The pyrolysis behavior and kinetics of the aqueous fraction of bio-oil were studied through thermogravimetric (TG) analysis. Based on the experimental data, activation energies and kinetic parameters were calculated by the Achar differential method and the Coats-Redfern integral method, then the most probable mechanism functions and kinetics model were… (More)
Catalase (EC 18.104.22.168) is an important antioxidant enzyme that protects aerobic organisms against oxidative damage by degrading hydrogen peroxide to water and oxygen. In the present study, a catalase cDNA of peal oyster Pincatada fucata (designated as PoCAT) is cloned and characterized by expressed sequence tag (EST) and rapid amplification of cDNA ends… (More)
The pearl oyster Pinctada fucata is commonly cultured for marine pearls in China. To culture pearls, a mantle piece from a donor pearl oyster is grafted with a nucleus into a receptor. This transplanted mantle piece may be rejected by the immune system of the recipient oyster, thus reducing the success of transplantation. However, there have been limited… (More)
Due to the large errors of traditional aerodynamic 4D trajectory prediction models, a prediction model based¿@on concept tree ¿Amulti-layer spatial association rule mining flight track data¿@was proposed. Firstly, the factors that had impact on total flying track were found out from flying history, and the flying track o f next flight w as predicted. Then… (More)
We propose a method to store XML document with time certification into relational database. We take into account update of XML document. The proposal database stores necessary information to generate XML document with time specifiication at a certain time. The relational database schema and XML generation algorithm are described.
