半衰期

During the ESR study of the effects of oxLDL on the ESR signal intensity of hydroxyl radicals in collagen (2 μg/ml)-activated platelets, we found that incubation of human platelets with collagen produced a typical four-line hydroxyl radical signal and a long-lived g = 2.005 radical detectable by spin trapper 5,5-dimethyl-1 pyrroline N-oxide.

在研究oxLDL降低由collagen 〈2 μg/ml〉刺激血小板产生的氢氧自由基〈OH●〉的ESR讯号强度的同时，我们发现以DMPO当自由基捕捉剂，collagen除了刺激血小板产生一个四线的典型氢氧自由基之外，还产生一个长半衰期 g = 2.005的自由基。

Northern blot analysis of iNOS expression and iNOS stability revealed that bismuth subgallate (100 μM) significantly reduced the amount of iNOS mRNA and increased iNOS mRNA degradation. Because expression of iNOS is mediated by transcription factor, NF-κB, in the transcriptional level and immunosuppressor, TGF-β, at the post-transcriptional level, we examined the effect of bismuth subgallate on TGF-β1 production and NF-κB activity.

在本实验中，我们发现仅bismuth subgallate会减少以interferon-γ and lipopolysaccharide活化之RAW 264.7 巨噬细胞株中一氧化氮之含量，我们进一步以北方墨点分析iNOS mRNA含量及iNOS mRNA稳定性，结果显示处理bismuth subgallate的活化巨噬细胞中，iNOS mRNA含量较未处理之细胞明显地减少约60%，其iNOS mRNA半衰期较未处理之细胞明显地减少约50%。

The proliferation of scholarly sources in the mass communication field adds to the information explosion that routinely abbreviates the useful half-life of knowledge throughout the discipline.

大众传播领域学术来源的扩散导致了信息爆炸，而信息爆炸简化了整个学科有用的半衰期知识。

The detection of aflatoxin albumin adducts in serum has been used to investigate the relationship between aflatoxin exposure and HCC.

血清中AFB ALB可作为一种暴露生物标记物，因它在体内的半衰期较尿中

Previous studies have indicated that intrathacheal administration of rhSOD is well tolerated with significantly increasing in SOD concentrations and activity in serum,tracheal aspirates and urine within 3 days in premature infants with RDS.

已有研究表明，rhSOD可减轻内毒素所诱导的肺损伤；且rhSOD气管内给药具有安全、吸收快、半衰期长的特点，还具有抗炎作用。

Percent of chlorine dioxide is be egested in 72 hours. The half-life in mice blood plasma is 44 hours.

其中43%在72小时内会经由尿液或粪便排出，吐气时并没有侦测出任何含量，在大鼠血浆中的生物半衰期为44小时。

By that is meant the time which elapses before half of the existing atoms have disintegrated or exploded.

这里所指的半衰期是现存原子的一半发生衰变或爆炸所消耗的时间。

It emits beta- and gamma-rays and has a half-life of 30 years.

它发射贝他和珈玛射线，且具有30年的半衰期。

IV administered DMPS has a half life of approximately 2 hours, with over 95% being excreted in 12 hours.

静脉注射DMPS半衰期约2小时，超过95%会在12小时内排出。

The results indicated that with the concentration of 100 mg kg^(-1) DEHP in soil, the inoculation of the two strains and their mixture could significantly accelerate the degradation of DEHP. The half life of residual DEHP was 32~48 days fewer than the control without inoculation, but there was no significant difference between the different inocula under the same condition.

结果表明，在土壤初始DEHP浓度为100mg kg^(-1)的条件下，接种两种降解菌及其混合菌悬液都可显著提高土壤中DEHP消失的速率，其残留半衰期比不接种对照缩短了32~48d，但在相同条件下接种不同降解菌的处理之间没有显著差异。
