1) Loss of imprinting
印迹缺失
2) track absence
航迹缺失
1.
Other problems of OTHR are low detection probabilities,low measurement accuracy and low data-sampling rate,which usually results in track absence in some radar dwells or the case that tracks of some modes may be never initialized.
针对天波超视距雷达在雷达坐标系下跟踪目标时,多路径传播效应下的各模式航迹起始与终结时刻不同而造成航迹缺失条件下的航迹融合问题,本文给出一种自适应天波超视距雷达航迹融合算法,通过应用当前时刻获得的新信息与历史时刻获得的信息联合确定最优关联假设,从而获得最优的目标状态估计。
3) loss of imprinting

Objective To develop a simple and rapid method of reverse transcription polymerase chain reaction(RT-PCR) and restriction fragment length polymorphism (RFLP) to analyze loss of imprinting(LOI) of insulin-like growth factor Ⅱ (IGF-2) gene in acute myeloid leukemia(AML) and chronic myeloid leukemia(CML).
目的 建立逆转录聚合酶链反应 (RT PCR)结合限制性片段长度多态性 (RFLP)技术 ,分析急、慢性髓性白血病的胰岛素样生长因子 2 (IGF 2 )基因的印迹丢失 (Lossofimprinting ,LOI)。
2.
Methods Selection of heterozygous cases for Apa Ⅰpolymorphism within exon 9 of IGF 2 gene and further analysis of loss of imprinting(LOI) were done in 26 AML patients by polymerase chain reaction(PCR),reverse transcription PCR(RT PCR) and restriction fragment length polymorphism(RFLP) technique.
方法 根据IGF2基因第9外显子具有Apa位点多态性,利用聚合酶链反应(PCR)结合限制性长度多态性技术,对26例AML患者骨髓细胞IGF2基因进行杂合子筛选,并进一步检测杂合子个体该基因的印迹丢失(lossofimprinting,LOI)。

补充资料：“诺森”印迹法
分子式：
CAS号：
性质：又称RNA印迹（法）。与DNA斑迹法过程类似的技术。用于从凝胶中转移出RNA片段转移至硝酸纤维素膜，尼龙膜等，并用探针进行杂交（称“北方”杂交）以显示目的区段的位置。显示RNA的大小及丰度。
