特异性

Using this microarray, we identified genes showing altered expression in different radiosensitive lung cancer cell lines. To provide independent confirmation of microarray data, semiquantitative RTPCR was performed on four genes.

In above mentioned conditions, the number of vessel ramification and ratio of vessel area/CAM area in VEGF group were 128.4±10.02 and 7.44±1.36 respectively, so there was no difference between PMP and VEGF groups. It is concluded that PMPs show promotive effect on the formation of capillaries in chick chorioallantoic membranes.Key words platelet??

而在对照组无特异性密集血管生成，血管分支数为82.6±8.05，血管面积为1.78±0.33，二组比较有显著性差异（P＜0.05）；而与VEGF组比较，后者的血管分支数为128.4±10.02，血管面积为7.44±1.36，二组比较差异无显著性。

Wheel' pattern were shown around mixed fibrous filter membranes, number of vessel ramification was 112.5±11.31 and ratio of vessel area/CAM area was 6.19±1.29﹪, but there were not localized allantoic vessels developing in the control group, the number of vessel ramification and ratio of vessel area/CAM area in control group were 82.6±8.05 and 1.78±0.33 respectively, so there was significant difference between PMP and control groups. In above mentioned conditions, the number of vessel ramification and ratio of vessel area/CAM area in VEGF group were 128.4±10.02 and 7.44±1.36 respectively, so there was no difference between PMP and VEGF groups.

结果显示：当 PMP的浓度为80 μg/ml时，孵育72小时后混合纤维素滤膜周围可见到放射状密集生长的血管网，血管分支数为112.5±11.31 ，血管面积为（6.19±1.29）﹪，而在对照组无特异性密集血管生成，血管分支数为82.6±8.05，血管面积为1.78±0.33，二组比较有显著性差异（P＜0.05）；而与VEGF组比较，后者的血管分支数为128.4±10.02，血管面积为7.44±1.36，二组比较差异无显著性。

The sensitivity and specificity ranged from 0% to 100% and 62% to 92%, respectively.

敏感度和特异性的范围分别从0%到100%和62%到92%。

This QC-PCR detection method is easy to operate with high specificity and sensitivity and is good for detection of ratoon stunning disease.

As the specificity of real estate, a complete set of real estate goods, not just as simple as a house, a commodity once the process of its use, brand re-entered the build brand awareness.

作为特异性房地产，一套完整的房地产商品，而不仅仅是一个简单的房子，一种商品一旦使用过程中，品牌重新进入建立品牌知名度。

The specific imprinted sites could selectively rebind the template, resulting in the slower permeation of the template. And the size effect means that the smaller the size is, the faster the template transports.

特异性识别位点会选择性地识别模板分子，从而使其渗透速度减慢；尺寸效应主要体现在底物蛋白的体积越小其渗透越快。

The potency of morphine and the competitivity of the blockingeffect points to a specific mechanism at a receptor site ratherthan an unspecific membrane effect.

吗啡的效能竞争性制作用说明了吗啡作用于某一受体部位的机制，而非对细胞膜的非特异性作用。

Many experiments suggested that homologous and site-specific recombination is the promising direction to solve this problem.
