| 1 | The Role of RNA Structure in Posttranscriptional Regulation of Gene Expression显示文摘当更多的信息在抄写和翻译的机制上被聚集,这些过程高度被调整,正在变得明显。第二等的 mRNA 和第三级的结构的形成是一个如此的规章的过程直到最近,它没深入地被分析。这些 mRNA 结构的形成有潜力提高并且禁止抄本的其他的拼接,并且调整翻译的率和数量。当,这规章的机制潜在地在 transcriptional 和翻译水平影响潜在地也利用非编码的 RNA 的广阔数组,它保证进一步的调查。当前,包括 RNA 结构(同等) 的平行分析的许多高产量的定序技术,定序的破碎(FragSeq ) 和选择 2 氢氧根 acylation 由教材扩展(形状) 分析了在 mRNA 的染色体宽的鉴定和分析带路结构形成。这些新定序技术加亮 transcriptome 的差异和复杂性,并且表明能为新治疗学的途径成为一个目标的另一规章的机制。 | Elina Jacobs James D.Mills Michael Janitz | 2012 | Journal of Genetics and Genomics2012，39，10： | 3 |
| 3 | Geochemical and Nd-Sr Isotopic Compositions of Hypabyssal Adakites in the Torud-Ahmad Abad Magmatic Belt,Northern Central Iran Zone:Analysis of Petrogenesis and Geodynamic Implications显示文摘Eocene intermediate to felsic subvolcanic rocks of the Torud-Ahmad Abad magmatic belt(TAMB),in the northern part of the Central Iran zone,are exposed between the Torud and Ahmad Abad regions in South-Southeast Shahrood.These igneous rocks include hypabyssal dacite,trachyte,andesite,trachy-andesite,and basaltic andesite;they are mainly composed of phenocrysts and microcrystalline groundmass of pyroxene,amphibole,and plagioclase,with minor biotite and titanomagnetite;they form domal structures(plugs and stocks),dikes,and sills that intruded into Neoproterozoic to cogenetic Eocene volcano-sedimentary sequences.Based on isotopic analysis of these intermediate to acidic rocks,initial ratios of^(143)Nd/^(144)Nd range from 0.512775 to 0.512893 and initial ratios of^(87)Sr/^(86)Sr range from 0.703746 to 0.705314,with quite positiveε_(Nd(i))values of+3.69 to+6.00.They are enriched in light rare earth elements and large ion lithophile elements and depleted in heavy rare earth elements and high-field strength elements,the SiO_(2) content is(52-62)wt.%,and Na_(2)O content>3 wt.%,Al_(2)O_(3) content>16 wt.%,Yb<1.8 ppm,and Y<18 ppm.These geological,geochemical,and Sr and Nd isotopic data are consistent with adakitic signatures originating by partial melting of the subducted Neo-Tethys oceanic slab(Sabzevar branch)and lithospheric suprasubduction zone mantle.The mantle signatures typifying the rapidly emplaced adakitic rocks(slab(high-silica adakite)and suprasubduction zone(low-silica adakite)melts)together with their locally voluminous extent are evidences that support a locally extensional geodynamic setting;and the evidence is consistent with an evolution to local transpression in the Late Eocene in this convergent margin are environment to rifting(basalts to adakites)towards submarine conditions in the Neogene. | Fazilat Yousefi Ryan D.Mills Mahmoud Sadeghian David R.Lentz Christina Wanhainen Habibollah Ghasemi Laicheng Miao | 2021 | Journal of Earth Science2021，32，6： | 0 |
