Novel Marek's Disease Virus Vector Vaccine Provides High Protection against Very Virulent Marek's and Infectious Bursal Disease Viruses in Chickens with or without Maternal Antibodies

中国化学会第九届全国无机化学学术会议

MoP was prepared by the pyrolysis of Mo-P complexes under H2 and Ar atmosphere respectively, and characterized by XRD, TEM, and other analysis techniques. The catalytic performance of the catalysts prepared by alkalinization of the as-prepared Mo P with K2CO3 was evaluated for syngas conversion to mixed alcohols. The effects of preparation methods on the structural characteristic and catalytic performance of Mo P-based catalysts were discussed. It was found that the MoP prepared by pyrolysis method exhibited smaller particle size and higher dispersion as well as more active sites compared to the Mo P prepared by the traditionally temperature-programmed reduction（TPR） method, thus they performed higher total alcohols selectivity, CO conversion and total alcohols STY respectively, for synthesis gas conversion to alcohols.

Dear Editor,Infectious bursal disease (IBD) is one of the most important diseases of the poultry. The IBD virus (IBDV), a nonenveloped virus belonging to the Birnaviridae family with a genome consisting of two segments of double-stranded RNA (segments A and B), targets B lymphocytes of bursa of Fabricious leading to immunosuppression. In Pakistan,poultry farming is the second biggest industry and IBD is the second biggest disease threating the poultry ***.

Objective： To test whether IL-1 RI/My088-TIR mimic AS-1 can work as a new compound that targeted at blocking MyD88- dependent signaling pathway, we investigated the physical structure and biological function of AS-1. Methods：The crystallographic structure of AS-1 was examined by 1^H nuclear magnetic resonance. The toxicity of AS-1 was measured with Methyl thiazolyl tetrazolium （MTT） assay. The effect of AS-1 on phosphorylation state of p38 MAPK and IRAK-1 was observed with Western blot. Results：The crystallographic details of AS-1 demonstrated that it was a tri-peptide sequence[（F/Y）-（V/L/I）-（P/G）] of the IL-1R I -TIR domain BBloop. No toxicity of AS-1 was shown to HEK 293A cells. The phosphorylation of p38 MAPK, induced by IL-1β significantly increased from those in the control group. AS-1 significantly reduced the phosphorylation of p38 MAPK induced by IL-1β. IL-1β increased the phosphorylation of IRAK-1 significantly, which was prevented by AS-1. Conclusion：AS-1 is a competitive mimic between IL-1R I-TIR and MyD88-TIR domain, which most likely interferes with MyD88-dependent signaling pathway.
