Cu isotopes (e.g.Cu-64 and Cu-67) increasingly find use in nuclear medicine.Accordingly fast,reliable and easily automatable methods for the production of these isotopes are of great interest.A Cu selective extraction chromatograghic resin (CU Resin,Triskem International) developed for the fast and selective separation of Cu was characterized.Based on the obtained results,a method for the separation of Cu,and its purification from irradiated Ni or Zn targets was developed and tested on simulated Ni and Zn targets,and on an irradiated natural Ni target.Cu yields and decontamination factors for potential interferences have been determined for the developed method.It could be shown that the CU resin has high selectivity over the tested interferences and that Cu can be recovered with high yield and purity in a small volume of 8M HCl within few minutes separation time.A method for the conversion of the Cu elute to lower acid concentrations / higher pH values has equally been developed.

掌按小腹和摇头二法及食疗说也载于明代周于蕃所辑《小儿推拿秘诀》中，文字基本无异，就是内容的次序不同。据《秘传推拿妙诀》和《小儿推拿秘诀》的成书时间分别为1776年、1605年，结合《按摩仙诀》在钱汝明幼时由钱父获得，就算钱汝明著书己在古稀之年，《小儿推拿秘诀》成书时间也早于钱父获得《按摩仙诀》的时间，即《按摩仙诀》的内容很可能参考了《小儿推拿秘诀》。张廑云先生《按摩仙诀》的学术思想归纳为：重视推拿

目的:肺癌放疗中辐射抗性问题受到广泛关注,一些原癌基因的激活会影响到肺癌病人的预后.因此,在前期辐射应答基因STAT3 的工作基础上,探索其上游相关信号传导通路,为肺癌临床放疗方案治疗提供理论依据.方法:0-10Gy 60Coγ 射线照射分别照射肺腺癌 p53 野生型和突变型细胞株H322,照后0-24h 提取蛋白,利用Western blot 方法、ELISA、免疫荧光染色和双荧光报告载实验,分
目的 G-CSF 是救治辐射急性损伤的有效细胞因子,有研究显示临床应用G-CSF 治疗辐射急性损伤同时可能造成造血干细胞(HSC)的远期损伤.本研究旨在探究G-CSF 救治辐射损伤对造血干细胞功能的远期影响.方法C57 小鼠随机分为对照组、照射组(6Gy)、治疗组(6Gy+G-CSF)；全身照射后2h 开始,治疗组小鼠注射G-CSF(两次/日,1ug/次),其他组注射等量生理盐水,连续给药一周,
集簇性损伤是电离辐射诱导的DNA损伤中最严重的一种,含双链断裂(DSB)的损伤即是集簇性损伤的一种,被认为是最危险的损伤.在细胞修复的过程中,非双链断裂(non-DSB)的簇损伤位点,若未能完全修复则可能形成附加的DSB,继而引起细胞的死亡、突变和转化.有数据指出,DNA损伤的复杂性和严重性随着传能线密度(LET)的增加而增加,并引发高突变率和癌的发生.因此,研究高LET辐射与生物物质的相互作用极
