查询词典 specificity

Results The DNA was obtained from PPJ through a nasopancreatic tube. Aberrant p16 methylation and K- ras gene mutation were detected in the same samples of PPJ. Sensitivity,specificity,positive predictive values,negative predictive values and accuracy of HE staining for pancreatic cancer were 40%,100%,100%,45.4% and 60.0%,respectively. Of the 20 cases of pancreatic cancer,K- ras gene mutation was detected in 14 (70%) and the p16 gene was shown to be methylated in 7 (35%). Of the 8 cases of chronic pancreatitis,K-ras gene mutation was detected in 2 (25%). Of the 2 cases of mucinous cystoadenoma of pancreas,K-ras gene mutation was detected in 1 (50%). Aberrant methylation of p16 was not detected in pancreatic juice samples from patients with chronic pancreatitis and mucinous cystoadenoma of pancreas.

结果 所有胰液标本均成功抽提出DNA，30例胰腺疾病病人胰液标本同时进行了K-ras基因突变和p16基因启动子区5′CpG岛甲基化检测，其中20例胰腺癌病人胰液中K-ras基因突变率为70%（14/20），p16基因甲基化率为35%（7/20），8例慢性胰腺炎中K-ras基因突变率为25%（2/8），2例胰腺囊腺瘤病人中K-ras基因突变率为50%（1/2），慢性胰腺炎和胰腺囊腺瘤病人胰液中无p16基因甲基化。

Clearly, new modes of therapy are necessary. The crux is to increase the specificity of cytotoxic drugs.

因此在不降低药效的情况下尽量减少化疗药物的剂量、提高抗白血病药物的选择性就成了问题的关键。

Objective Establishment of a hybridoma cell line secreting a monoclonal antibody to facilitate iˉdentification of human tissue kallikrein（KLK1gene,hK1protein）.Methods Mice were immunized with E.coli-exˉpressed GST-hK1fusion protein and their spleen cells were fused with SP2/0myeloblastoma cells.Specificity of the monoclonal antibody was shown by Western blotting and by immunofluorescence.Results The monoclonal antibody reacted specifically to E.coli-expressed hK1and with the KLK1cDNA-transfected COS-1cells.

目的 将人组织激肽释放酶（基因命名 KLK1，酶命名为hK1）cDNA克隆入肠杆菌表达质粒，以重组菌表达的GST-hK1融合蛋白免疫小鼠，获得了分泌hK1特异单克隆抗体的杂交瘤细胞株方法将KLK1cDNA克隆入真核表达质粒，用获得的重组质粒转染COS-1细胞，经间接免疫荧光试验证明，上述单克隆抗体能与转染细胞发生特异反应。

Contentment, desireless natural heart water fact from us very distant only hopefully we can more 1:00 enthusiasm into life this marathonIn simpler, natural point less fear suspected, multi a persistent specificity, even it is a dream, each time we fetch easiest nearest piece chocolate it where sweet waiting you.

知足常乐、无欲自然心如水其实离我们非常遥远，只但愿我们能多一点热情投入到人生这场长跑中，简单一些、自然一点，少一些恐惧怀疑、多一份执着专一，哪怕它就是一个梦呢，每次我们去拿最简单最接近的那块巧克力，它就在那里，甜蜜的等待着你。

The combination detection of three antibodies can improve the specificity for the diagnosis and is helpful to the early diagnosis of RA. The bone erosion is more severe in the patients with detectible two positive antibodies.

三种抗体联合检测可提高对RA诊断特异性及诊断率；两种以上抗体阳性RA患者，骨破坏更严重。
