This shows directly that increased sensitivity to nucleases is associated with the exclusion of nucleosomes.

在20%以上的例子中，在核小体组织中可以看到一个&裂孔&，图27.39是一个具体的例子。

Chapter two is concerned with the syntheses and characterization of some chiral ligands and consists of relevant mechanism of reaction( for example, N anion acts as nucleophilic reagent and different nitriles act as reacting substance).

第二章讨论了若干手性配体的合成与结构，并包含了相关反应的机理探讨(例如N~-做为亲核试剂、不同的腈作为反应底物)。

SHRIMP U-Pb concordia ages of the cores of rounded zircons are 620 and 219 Ma, suggesting that the parental magma for the quartz diorite porphyry may have been derived from partial melting of basement materials of the South China block that had been modified by ultrahigh-pressure metamorphism.

具有细微震荡环带岩浆锆石的SHRIMP U-Pb年龄(117.7±1.6 Ma)显示该石英闪长斑岩体的形成时间为早白垩世；浑圆状锆石核部SHRIMP U-Pb谐和年龄为620 Ma和219 Ma，这表明该石英闪长斑岩的母岩浆可能起源于经历了超高压变质作用改造的华南地块基底物质的部分熔融。

The tower structure comprises an external steel frame, an elliptical concrete core and steel-framed floors between them.

塔体由椭圆型钢结构外筒和混凝土核芯筒以及连接这两者的钢-混凝土组合结构楼面组成。

Methods: Nine patients with severe systemic lupus erythematosus were treated with DNA immunosorbent column 3 times respectively, and parameters such as the titer of anti-nuclear antibody, anti- double-stranded DNA antibody titer, Complement C3, erythrocvte sedimentation rate, routine test of blood, kidney function and liver function were observed before and after the treatment, the results were analyzed statistically.

应用DNA免疫吸附柱对9例重型系统性红斑狠疮患者分别治疗3次，观察吸附治疗前、后抗核抗体滴度抗双链DNA抗体滴度、补体C、血沉、血常规、肾功能、肝功能等指标并行统计学分析。

BACKGROUND: Studies demonstrated that incisor continuously growing is due to lack of epithelial root sheath formation. However, researches regarding whether receptor activator of nuclear factor κB ligand and osteoclast has correlation with continue root development is poorly understood.

背景：研究表明小鼠不断生长的切牙是由于切牙仅有颈环而无上皮根鞘的形成，但是破骨细胞分化因子核因子κB受体活化剂配体和破骨细胞与不断生长的牙根发育是否相关，目前研究较少。
