In response to TCDD exposure, AhR nuclear translocator forms a heterodimer with the aryl hydrocarbon receptor after the ligand-dependent translocation of AhR to the nucleus, and eventually the complex binds to the xenobiotic response elements, which promote transcription of several specific genes, such as CYP1A1.However, the diverse effects of TCDD could not be simply explained by the AhR pathway.

对於戴奥辛的毒性机制，以往的研究认为与芳香基碳氢化合物受体（arylhydrocarbon receptor－AhR）的活化有关；TCDD 活化了AhR，被活化的AhR 从细胞质转移到细胞核内，在细胞核与另一个蛋白质AhR nuclear translocator形成二聚体，并与DNA 上的xenobiotic regulatory element结合，诱发某些基因（如：CYP1A1）的转译与表现；不过，单从AhR的代谢途径并不能解释所有生物上的毒性现象。

The ligand was used to prepare for a series of its transition metal complexes by the replacement reaction with metal salts.

After the completion of reaction, ether is added to the resulting mixture to precipitate the tartrate and filter to recover the ligand. The recovered ligands keep good enantioselectivity only in first recycle, but compared with solution-phase of tartrate counterpart, using of soluble polymer-supported tartrates largely simplifies the workup of sharpless epoxidation.

反应完成后，向反应体系中加入乙醚使配体沉淀，过滤即可回收配体，虽然回收的配体只在第一次循环中保持了较好的对映选择性，但与使用小分子酒石酸酯配体相比，使用可溶性聚合物支载的酒石酸酯极大地简化了Sharpless环氧化反应的后处理。

Copper fixation rate affected by retention, fixation time, ligand type, and addictive. For all formulations, while other three conditions is the same, copper fixation rate of preservatives with low retention level is less than those with higher retention level; copper fixation rate of oven-dried bamboo samples is less than air-dried bamboo samples; copper fixation rate of amine-based preservatives is less than ammonia-based ones; copper fixation rate in some formulations containing carbonate and phosphate is higher than non-carbonate and non-phosphate ones.

In mammals the Notch gene family comprise four related genes, Notch1-4, as the Notch ligands that encode transmembrane proteins.
