Scientists have identified the first biochemical marker linked to sleep loss, an enzyme in saliva known as amylase, which increases in activity when sleep deprivation is prolonged.
经研究发现首个与失眠有关的生化标记。该标记是唾液中的一种酶,学名淀粉酶。当延长睡眠剥夺时间时,这种淀粉酶的活性就会随之增高。
Methods Myocardial biochemical marker was measured in 80 patients diagnosed as having acute alcoholism and its relation to incidence of cardiac event was analyzed.
方法检测80例急性酒精中毒患者心肌生化标记物,并比较分析其心脏事件发生率。
Result 13 biochemical marker loci of the 27 loci showed polymorphism in the whole population, and the polymorphism rate was 48.1%.
结果生化基因位点中有13个位点在整体中呈现遗传多态性,多态率为48.1%;
Conclusion Hcy can be used as a biochemical marker of liver diseases and has a certain value in diagnosis of primary HCC.
结论同型半胱氨酸可作为反映肝脏疾病的生化指标之一,且对原发性肝细胞癌具有一定的诊断价值。
The results showed DNA fingerprinting map with good polymorphism can distinguished different sorts of inbred mice regardless of biochemical marker analysis.
研究还表明,用同一方法重复同一基因组DNA的指纹图时,获得相同的实验结果。
The VEGF levels of preterm infants is significantly lower than that of term infants, so the VEGF levels of preterm infants may be a useful objective biochemical marker of premature delivery.
早产儿脐血VEGF水平较足月儿下降,提出脐血VEGF水平可以作为反映胎儿是否发生早产的一个指标。
For example, scientists can search for a biochemical marker that is tied to certain species of algae that live only in ice.
例如,科学家可以借此寻找一个与仅在冰中生存的某些藻类物种相关的生化标记物。
CRP, which is increased in pregnancy with preeclampsia, may be a sensitive biochemical marker for early diagnosing of preeclampsia.
CRP水平在子痫前期时显着增加,可能成为临床早期发现子痫前期发病的一个灵敏指标。
Methods:DNA fingerprinting was used to analyze 8 nation_wide known colonies of 6 inbred rat strains and compared with biochemical marker analysis.
方法:采用DNA指纹图法对国内已知的6个品系8个近交系大鼠群体进行分析,并与常规生化标记分析法进行比较。
ConclusionThe plasma BNP concentration appears to be a biochemical marker of an increased risk of all-cause mortality in patients with heart failure, especially multiple organ dysfunction.
结论BNP水平是心力衰竭患者死亡危险增加的一个生化指标,是影响患者预后的一个重要危险因素。
