Acting as an antenna molecule in the supramolecular system, Mg(superscript 2+)-HA remarkably enhances the photoinduced electron transfer efficiency between C60 and an electron donor, N, N-dimethylaniline.

作为超分子体系中的光捕获分子，Mg(上标 2+)-HA能显著地提高C60与N，N-二甲基苯胺的光诱导电子转移反应效率，生成的C60负离子自由基的电子自旋共振光谱信号强度比未加入Mg(上标 2+)-HA时增强了9倍左右。

Happy people tended to have twice as many substantive conversations, and spent 25 percent less time alone, than the unhappiest participants.

比起最不高兴的参与者来说，心情愉悦的人倾向于有两倍的意义谈话，不足百分之二十五的时间是单独相处。

Polymorphism of HLA-DQB1 promoter region in Hans IDDM patients and normal controls have been identified by PCR, PCR/SSCP and PCR/sequencing methods.No differences were found in y and s box between patients and controls carrying different allele as well as in different ethnic groups. There are two different sequences in x box,but CCTAGAGACAGATT sequence locates frequently on the haplotype with DQB1.0302 allele. Polymorphism between transcription point and y box (at position －44～-46 and －59～-61) might be associated with the genetic susceptibility to IDDM. Additionally,a new single base mutant (CACC→CAC A ) was found at position －131 and －128 in two patients carrying DQB1.0601 allele.

结果显示携带不同等位基因的患者与对照者DQB1 5'-调控区y、s box核苷酸序列相同，且与白种人基因结构一致；y box核苷酸序列存在二种结构，CCTAGAGACAGATT序列常常与DQB1.0302等位基因在同一单倍型；转录起始位点至y box间-44至-61位存在多态性，-59至-61位AAG等位基因可能与1-型糖尿病易感相关联；在2例携带DQB1.0601等位基因患者的-131至-128位间发现CACC→ACA A单个碱基取代突变。
