Tris)(η 5.cyclopentadienyl-μ-carbonyl-iron)-μ3-nitrosyl cluster was obtained from the reaction of cyclopentadienyl dicarbonyliron dimer with nitrogen monoxide in xylene. The cluster was characterized by elemental analyses, IR, MS and 1. NMR. The crystal structure of [(η5.C5.5.(μ-CO)Fe]3(μ3-NO).C4H8O was determined by X-ray diffraction analysis. It crystallizes in the orthorhombic space group Pnma, a=9.05.(2), 6=1..5.5.2), c=22.5.5.4) A, V=21.0.3(7) A3, Z=4,Dc=1.68 ***-3; structure solution and refinement based on 1.41.reflections with I > 3.0 (I) (MoKa, A=0.71.73 A) converged at R=0.05.0. The infrared absorption band at 1.25.cm-1.of the μ3-NO in the cluster, which is red shifted, shows that μ3-NO is activated.

In this study we used U01.6, a potent and specific inhibitor of MEK, to study the roles of MEK/ERK/p90rsk signaling pathway in the meiotic cell cycle of mouse oocytes. The phosphorylation of MAP kinase and p90rsk in the oocytes treated with 1.5.μM U01.6 was the same as that in oocytes cultured in drug-free medium. With 1.5.μM U01.6 treatment, the spindles appeared normal as they formed in oocytes, but failed to maintain its structure. Instead, the spindle lost one pole or elongated extraordinarily. After further culture, some oocytes extruded gigantic polar bodies （>30 μm） that later divided into two small ones. Some oocytes underwent symmetric division and produced two equal-size daughter cells in which normal spindles formed. In oocytes with different division patterns, MAP kinase was normally phosphorylated. When the concentration of U01.6 was increased to 1. mM, the phosphorylation of both MAPK and p90rsk were inhibited, while symmetric division was decreased. When incubating in medium c

In this study, we constructed recombinant plasmid pcDNA3.1.P1.X3C3D including P1. 2A, 3C, 3D and part of 2B gene of FMDV and pcDNA3.1.IFN containing the gene encoding bovine IFN-α. We inoculated the DNA vaccine pcDNA3.1.P1.X3C3D with or without pcDNA3.1.IFN to evaluate the effi- ciency of this DNA vaccine and the immunogenicity of DNA vaccine enhanced by the co-delivery with pcDNA3.1.IFN. After two times of vaccination with DNA vaccine, all of guinea pigs were challenged with 1.3 ID5. FMDV type O. Anti-FMDV antibody levels were detected by ELISA and T lymphocyte proliferation response was tested by MTT assay. The result shows that guinea pigs inoculated by pcDNA3.1.P1.X3C3D alone or with pcDNA3.1.IFN generated specific antibodies and induced an FMDV-specific T lymphocyte proliferation response. FMDV challenge tests showed that one in four guinea pigs immunized by pcDNA3.1. P1.X3C3D with pcDNA3.1.IFN was protected from the FMDV serotype O infection. This result indicated that the efficiency of the DNA vaccine was enhanced by co-delivery with pcDNA3.1.IFN. However, the protection rate was considerably lower than that immunized with conventional FMD vaccine.

1.IntroductionPorous biodegradable synthetic materials such as β-tricalcium phosphate (β-TCP) and poly L-lactic acid(PLLA) are usually used in bone tissue ***, proper ratio, optimum pore size and porosity of the composites of β-TCP/PLLA are not very clear yet. In this study, we chose osteo-induced rat bone mesenchymal stem cells (rMSCs) as seeding cells, and cultured them on β-TCP/ PLLA scaffolds with different ratio, different pore size and different porosity. The aim is to investigate the optimum construction for supporting cell growth, proliferation and differentiation.

With the commissioning of the Cooler Storage Ring at the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR),a pilot experiment operating the CSRe in isochronous mode to test the power of HIRFL-CSR for measuring the mass of the short-lived nucleus was performed in December of 2007. The fragments with A/q = 2 of 36Ar were injected into CSRe and their revolution frequencies were measured with a fast time pick-up detector with a thin foil in the circulating path of the ions. The preliminary result is presented. The result shows the potential of CSRe for mass measurements of short-lived nuclei.
