BACKGROUND The zebrafish intestine is a simple tapered tube that is folded into three sections. However, whether the intestine is functionally similar along its length remains unknown. Thus, a systematic structural and functional characterization of the zebrafish intestine is desirable for future studies of the digestive tract and the intestinal biology and(More)
CXC chemokines, which induce angiogenesis, have glutamine-leucine-arginine amino acid residues (ELR motif) in the amino terminus and bind CXCR2 and the Duffy antigen chemokine-binding protein. Duffy, a seven transmembrane protein that binds CXC and CC chemokines, has not been shown to couple to trimeric G proteins or to transduce intracellular signals,(More)
The spatio-temporal variations of soil gas in the seismic fault zone produced by the 12 May 2008 Wenchuan Ms 8.0 earthquake were investigated based on the field measurements of soil gas concentrations after the main shock. Concentrations of He, H2, CO2, CH4, O2, N2, Rn, and Hg in soil gas were measured in the field at eight short profiles across the seismic(More)
To investigate the effects of NaCl stress on plant growth, nitrogen assimilation, proline and soluble protein contents, and gene expression of enzymes of nitrogen metabolism, a hydroponic experiment using cucumber (Cucumis sativus L.) seedlings was performed. The seedlings were grown in nutrient solution supplemented with 0 or 84 mM NaCl for up to 9 days.(More)
Because of the complexity and diversity of human behavior, social systems are unpredictable and difficult to quantify. With the development of computer technology, scholars have begun to construct artificial systems to simulate real social systems in order to explore the trajectory of social phenomena. In this paper, we combined complex system modeling(More)
Hydrogeochemistry of 32 hot springs in the western Sichuan Province after the Wenchuan MS 8.0 earthquake was investigated by analyzing the concentrations of cation and anion and the isotopic compositions of hydrogen and oxygen. The water samples of the hot springs were collected four times from June 2008 to April 2010. Hydrogeochemical data indicated the(More)
In reality, manufacturers motivate sales agents to increase promotional effort with the sales rebate and penalty contract, the agents always concern about the fairness, and information flow structure among agents is a small-world network. In order to improve incentive performance under this situation, this paper builds a multi-agent model mainly to observe(More)
