Plyfil composite yarns is similar to two-ply yarn structures.
纺纱方法决定着成纱结构，成纱结构与纱线组成原料又决定了纱线的性能。sirofil复合纱线纺纱时长丝与短纤纱须条的间距及长丝的张力，plyfil复合线加工时二组分间并线张力对成纱结构及纱线的性能有着重要影响。sirofil复合纱的成纱横截面呈近似圆形结构，长丝位于成纱的一侧；纵向呈有"股线螺纹"的单纱外观。plyfil复合线具有类似于传统双股线的横截面和纵向外观。

Upon binding ATP or a nonhydrolyzable analog such as AMPPNP, RecA undergoes an allosteric transition into a high-affinity DNA-binding form. When RecA combines with dsDNA to form RecA-dsDNA nucleofiliment, it can unwind dsDNA and change the dsDNA structure.
在ATP或其类似物的辅助下，RecA可以直接与双股DNA结合而形成核丝，并将双股DNA加以解螺旋，并改变双股DNA的结构。

The results indicate that [(L 1) 2SnEt 2] can selectively bind to the N 1 atom of the base and the phosphate oxygen atom of AMP and may further destroy the helical structure of DNA, while the dimethyltin compound of 1,3 dimethyl 4 acetyl 5 pyrazolone [(L 1) 2SnMe 2] merely binds to the the phosphate oxygen atom of AMP and causes the contraction of DNA helical structure.
结论3 二甲基 4 乙酰基 5 吡唑酮的二乙基锡配合物(L1 ) 2 SnEt2 可与AMP 的碱基N1 和磷酸根氧原子螯合并可能会破坏DNA 的双股螺旋结构；而二甲基锡配合物(L1 ) 2 SnMe2 易与单核苷酸的磷酸氧结合，难以与单核苷酸的碱基氮原子稳定结合且只引起DNA 双股螺旋的收缩

By utilizing three benezenemulticarboxylate derivatives (H2chdc, H2aip, NaH2sip), we obtain 12 coordination polymers. Especially, compelexes 1 and 2 are based on one-dimensional ···OHInOHIn···chains as building units, while complex 3 is based on double four-ring [In8(μ2-O)4(μ2-H2O)8]16+, complex 4 is based on trinuclear In3(μ3-O)(CO2)6, complexes 11 and 12 are both based on nested bistranded helices.
选择了三类取代苯羧酸配体： 2，5-二羟基-1，4-对苯二甲酸(2，5-H2chdc)； 5-氨基间苯二甲酸(5-H2aip)； 5-磺酸基间苯二甲酸钠盐(5-NaH2sip)和InCl3反应合成了十二个配位化合物：其中1、2以···OHInOHIn···链为构筑单元， 3以双四元环[In8(μ2-O)4(μ2-H2O)8]16+为构筑单元，4以棱柱状三核铟In3(μ3-O)(CO2)6为构筑单元，而11、12以嵌套的双股螺旋链为构筑单元。

The central 5, 5'-disubstituted bipyridine units of each ligand coordinate theNi or Fe ion, while all the terminal 6-monosubstituted bipyridine units of the ligands keep free of coordination, as the result trinuclear triple-stranded helicate 〓 can not form. This is considered to be caused by the steric hindrance of the methylene substituents α to the chelating nitrogens of the terminal bipyridine units and the strain caused by linkage mode.
配体L〓与Ag作用得到〓，两个配体链相互缠绕着两个Ag离子周围形成双股螺旋结构并以头尾式排列(见图3)，由于配体中位于配位N原子α或β位的末端甲基或次甲基取代基的空间位阻阻碍了头对头式异构体的形成，也正是由于配体头尾式排列而使Ag双股螺旋得以形成，这一结果表明该螺旋体的组装过程中自发地采取了空间阻碍尽可能小的那个构型。

For maintain the genome integrity and fidelity. DNA repair processes are classified into pathways responsible for repairing specific classes of DNA damage, although recent data indicated that some proteins function in multiple pathways. Base excision repair occurs through excision of a damaged region, followed by fill-in repair synthesis using the opposite strand as a template. Mismatch repair operates on base mismatched and small loop-outs that arising during replication by misincorporation or slippage on the template strand. Nucleotide excision repair removes photoproducts from u.v. radiaton and bulky adducts from a multiple of chemicals. DNA double-strand breaks may be rectified by either homologous recombination repair and nonhomologous end joining pathways where both strands of the DNA duplex are damaged.
DNA修补基因可藉由不同的机制对不同程度的DNA损害进行修复，虽然近来已有文献指出，一些DNA修复蛋白可能参与多种DNA修复机制，不过一般可分为下列四种DNA修复机制：碱基删除修复(Base Excision Repair； BER)，即对较小的DNA损伤，进行修复；核苷酸错误配对删除修复，即对复制时所产生的核苷酸配对错误或模板滑动造成的DNA损害进行修复；核苷酸删除修复(Nucleotide Excision Repair； NER)，即对因紫外线或有机化合物所造成的较大损伤进行修复；以及双股DNA断裂修复(Double-Strand Breaks； DSBs)，即对双股DNA断裂进行修复，此机制又可分为同源染色体的重组与末端接合两种主要路径，对受损的DNA进行修复。
