| 1 | 利用洋底地震资料估算进入马里亚纳俯冲带的水通量显示文摘俯冲带水迁移是地表水进入地球深部的主要方式。但是,通过板块俯冲到底能够带入深部地幔多少水受到多种因素影响,包括俯冲带板片年龄、俯冲带几何性质、俯冲带热结构、板块汇聚速率等。目前关于俯;中带的水循环仍知之甚少。最近,华盛顿大学地球与行星科学系的Cai C博士等人收集和分析了马里亚纳海沟中心周围宽频洋底瑞利面波地震数据,估算了通过板块俯冲输入地球深部的水通量。他们的研究结果表明:板块俯冲带入深部地幔的水通量是以前估算的4.3倍,而且远大于目前对地幔输出水通量的估计。由于大量的长期净水流入地球深处与地质记录中的海平面稳定性不一致;同时也没有迹象表明马里亚纳俯冲带的板块弯曲区在形态和断裂强度与其它古俯冲带的对应区域对比有很大的不同。 | Cai C Wiens D A Shen W Eimer M 张宝华 | 2018 | 矿物岩石地球化学通报2018,37,6: | 13 |
| 2 | Identification and characterization of genes that control fat deposition in chickens显示文摘Background: Fat deposits in chickens contribute significantly to meat quality attributes such as juiciness, flavor,taste and other organoleptic properties. The quantity of fat deposited increases faster and earlier in the fastgrowing chickens than in slow-growing chickens. In this study, Affymetrix Genechip? Chicken Genome Arrays 32773transcripts were used to compare gene expression profiles in liver and hypothalamus tissues of fast-growing and slow-growing chicken at 8 wk of age. Real-time RT-PCR was used to validate the differential expression of genes selected from the microarray analysis. The mRNA expression of the genes was further examined in fat tissues. The association of single nucleotide polymorphisms of four lipid-related genes with fat traits was examined in a F2resource population.Results: Four hundred genes in the liver tissues and 220 genes hypothalamus tissues, respectively, were identified to be differentially expressed in fast-growing chickens and slow-growing chickens. Expression levels of genes for lipid metabolism(SULT1B1, ACSBG2, PNPLA3, LPL, AOAH) carbohydrate metabolism(MGAT4B, XYLB, GBE1, PGM1,HKDC1)cholesttrol biosynthesis(FDPS, LSS, HMGCR, NSDHL, DHCR24, IDI1, ME1) HSD17B7 and other reaction or processes(CYP1A4, CYP1A1, AKR1B1, CYP4V2, DDO) were higher in the fast-growing White Recessive Rock chickens than in the slow-growing Xinghua chickens. On the other hand, expression levels of genes associated with multicellular organism development, immune response, DNA integration, melanin biosynthetic process, muscle organ development and oxidation-reduction(FRZB, DMD, FUT8, CYP2C45, DHRSX, and CYP2C18) and with glycol-metabolism(GCNT2, ELOVL 6, and FASN), were higher in the XH chickens than in the fast-growing chickens. RT-PCR validated high expression levels of nine out of 12 genes in fat tissues. The G1257069A and T1247123C of the ACSBG2 gene were significantly associated with abdominal fat weight. The G4928024A of the FASN gene were significantly associated with fat bandwidth, and abdominal fat percentage. The C4930169T of the FASN gene was associated with abdominal fat weight while the A59539099G of the ELOVL 6 was significantly associated with subcutaneous fat. The A8378815G of the DDT was associated with fat band width.Conclusion: The differences in fat deposition were reflected with differential gene expressions in fast and slow growing chickens. | Hirwa Claire D'Andre Wallace Paul Xu Shen Xinzheng Jia Rong Zhang Liang Sun Xiquan Zhang | 2014 | Journal of Animal Science and Biotechnology2014,5,1: | 7 |
