These skew reflect mainly those in protein coding sequences, which are driven by asymmetric mutation pressures during replication and transcription (notably asymmetric cytosine deamination) plus subsequent selection for preferred structures, signals, amino acid or codons.

这些不对称性主要反应在蛋白质编码序列上，并且主要是受到复制与转录期间复制双股之间的不对称突变压力加上之后为了偏好的结构、信号、胺基酸或转录子的筛选所驱使。

The cis novel bisoxazoline ligands L1-L4 have been synthesized through the treatment of new cis dihydroxy diamide with p-toluenesulfonyl chloride in the presence of catalytic quantity of 4--pyridine, and the cis dihydroxy diamide could be achieved from the condensation of the amino alcohols and cis cyclopropane dicarbonyl chloride prepared via oxidation and halogenation from cis-2,2-dimethyl-3-formylcyclopropanecarboxylate with DCC.

我们以蒈醛酸内酯为起始原料，经过氧化反应、酰氯化反应得到顺式环丙烷二酰氯，然后在二环己基碳二亚胺的催化下与相应的氨基醇反应合成了顺式二羟基酰胺，再用对甲苯磺酰氯将羟基活化，最后在二甲氨基吡啶的催化下关环合成顺式双噁唑啉配体L1～L4。

The resultant was hydrogenised to remove protective group of amino group, then the product was reacted with NaNO2 to give diazonium salt, which was conjugated with salicylic acid, hydroxybenzene, N-salicyloyl glycine acid to get azo derivatives of 4-ASA.

本文首先对4-ASA的氨基和羟基进行了选择性保护，通过氢化还原法选择性脱除氨基的保护基，然后将氢化产物制成重氮盐，通过与水杨酸、苯酚和水杨酰甘氨酸发生反应生成4-ASA的偶氮衍生物，最后在碱性条件下水解得到最终产物。

The course will start with an overview of the central and peripheral nervous systems, the development of their structure and major divisions. The major functional components of the CNS will then be reviewed individually. Topography, functional distribution of nerve cell bodies, ascending and descending tracts in the spinal cord. Brainstem organization and functional components, including cranial nerve nuclei, ascending / descending pathways, amine-containing cells, structure and information flow in the cerebellar and vestibular systems. Distribution of the cranial nerves, resolution of their skeletal and branchial arch components. Functional divisions of the Diencephalon and Telencephalon. The course will then continue with how these various CNS pieces and parts work together.
