查询词典 lancelet amphioxus

These results also provedthe presence of the same acute phase response profile in amphioxus,as observed ineutherians.Thus it pushed the evolutionary existence of the eutherian-like acute phaseresponse back to the protochordate lineage.Fourthly,we determined CAs,including epinephrine、norepinephrin anddopamine,with HPLC method optimized after LPS challenged amphioxus.Theresults demonstrated that E,DE and DA are present in amphioxus humoral fluid,andE was firstly found in amphioxus.

第三，我们用生物化学方法，选取海洋中广泛存在、众多水产动物的常见致病菌-溶藻弧菌作为天然反应原感染文昌鱼，从另外一个角度探讨并丰富文昌鱼体液中的八种炎性蛋白的急性时相反应，结果显示，与LPS感染文昌鱼相比，六种正APPs的浓度变化幅度相对较小，曲线相对平缓，但仍然呈正急性时相反应，蛋白电泳也证实了这一点；而二种负APPs：RBP和白蛋白(Albumin，ALB)浓度实验周期内总体呈下降的趋势，呈负急性时相反应，结论与上述LPS相同。

However, there is no report about amphioxus Rab23 up to now except the annotations of two isoforms in the genome of Florida lancelet.

目前关于文昌鱼Rab23同源基因的研究仅局限于佛罗里达文昌鱼基因组中的注释。

Firstly,the presence and location of AAT in amphioxus was studied by Westernblotting and immunohistochemical methods.The results first revealed that AATpresent in amphioxus,a cephalochordate.Also it was demonstrated that AATdistributed in cellular plasma in hepatic diverticulum,the pouch that protrudesforward as an outpocketing of the digestive tube and extends along the right side ofthe posterior part of the pharynx,which has long been considered to be the precursorof vertebrate liver.In vertebrate,AAT is primary synthesized in liver.

我们首先利用免疫组化和Western blotting方法，研究了AAT在文昌鱼的组织表达和定位，首次在头索动物文昌鱼中证明了AAT的存在，结果显示，AAT定位于文昌鱼肝盲囊的细胞浆内，从AAT在文昌鱼中的合成部位来看，在功能上文昌鱼的肝盲囊等同于脊椎动物肝脏，肝盲囊是在发育分化过程中消化道组织向右前方突出沿着咽后部向前扩展和延伸形成的一个囊袋状结构。

These data give insight into the development mechanism and evolution of the amphioxus and vertebrates.A novel gene, AmphiSom, was identified in amphioxus Branchiostoma belcheri tsingtauense, and its sequence and developmental expression pattern were determined.

因此虽然文昌鱼不是脊椎动物的直接祖先，但是它是现存的与脊椎动物直接祖先最接近的无脊椎动物，是研究动物进化和动物胚胎发育的典型材料。

In this paper, the cloning, expression and phylogenetic analysis of AmphiSDHD and AmphiS27 from the gut cDNA library of amphioxus Branchiostoma becheri tisingtauense are carried out.AmphiSDHD, encoding the cytochrome b small subunit in mitochondrial succinate-ubiquinone oxidoreductase, was isolated from the gut cDNA library of amphioxus Branchiostoma belcheri tsingtauense.

本文从青岛文昌鱼(Branchiostoma belcheri tsingtaunese)肠cDNA文库中，分离得到克隆L095和094，经鉴定它们分别编码文昌鱼线粒体琥珀酸-泛醌氧化还原酶中细胞色素b的小亚基和核糖体蛋白S27(AmphiS27)。

The phylogenetic analysis based on the amino acids of invertebrate and vertebrate S19 proteins showed that the amphioxus protein was at the base of a clade of vertebrate S19 proteins, indicating that amphioxus is not only the sister group of extant vertebrates but also the basal lineage of chordates.

另外，AmphiS19与脊椎动物各S19蛋白在氨基酸水平上的相似性几乎是等同的。这些结果表明文昌鱼不仅是脊椎动物的姊妹类群，而且是脊索动物谱系进化过程中的基部类群。

A flexible rodlike structure that forms the main support of the body in the lowest chordates, such as the lancelet; a primitive backbone.

脊索细胞构成的一条纵长可弯曲的杆状结构，其作用是引导产生神经板，形成躯体的支持轴

Richards growth model and Schumacher growth model were used as the basal area growth model in establishing the basal growth prediction of Larynx lenses and Cunningham lancelet plantation in this study.

结果表明Riehards和Sehumaeher式在同时选择单位面积株数或同时选择林分密度指数作为自变量时，Schumacher式都比Richards式拟合效果好。

Study the diversity of chordates: lancelet, tunicate, lamprey, chondrichthyans, ray-finned fish, amphibians, reptiles, birds, and mammals.

A2， B2， G3 研习脊索动物的多样性－文昌鱼、海鞘、八目鳗、软骨鱼、硬骨鱼、两栖类、爬虫类、鸟类及哺乳类。

Recently, CK has been shown to be an acute phase protein in the humoral fluid of amphioxus B.

最近的研究表明文昌鱼体液中的CK是一种急性时相蛋白，但对其免疫功能知之甚少。

The statistical analysis of this large set of mutations has led us to propose a diagnostic strategy that should help with the molecular work-up of optic neuropathies.

这一大系列基因突变的统计学分析引导我们提出一个诊断策略，可以帮助我们对视神经病变进行分子学的诊断检查。

The results show that the pipe grouting changes the mechanical parameters of surrounding rocks to achieve the security of engineering objectives by reinforcing surrounding rocks and bolcking the water.

研究表明：小导管注浆一方面改变了围岩的力学参数，另一方面利用浆液的固结特性可以实现堵水和加固围岩的工程目标，使隧道在开挖过程中的安全得到保障。
