查询词典 dorsal

Blocking cyp11a1 expression results in impaired epiboly, convergence, and extension movement and disrupting hsd3b leads to expanded dorsal tissues in zebrafish embryos, yet little is known about the function of P5 and P4 in early developmental stages.

在之前的研究指出降低cyp11a1表现会造成细胞外包卵黄、聚合移动以及伸展移动的速度下降，而抑制hsd3b 表现则会使背部组织增大。

Although overexpression of Hspa5 does not cause detectable defects, its knockdown by injecting Hspa5 morpholino antisense oligonucleotides results in slower epiboly during gastrulation and dorsalized phenotypes at 24 hpf, including smaller and curled tail and absence of caudal ventral fin. When Hspa5 expresison in embryos is knockdown, the expression of the dorsal markers gsc and ntl is enhanced while the expression of ventral markers is reduced.

尽管在胚胎中过量表达Hspa5对胚胎发育没有明显影响，但是利用反义吗啉环寡核苷酸抑制胚胎中Hspa5的表达会导致胚胎外包变得缓慢，24hpf出现尾部变细或卷曲、缺少腹鳍等背部化的表型，同时gsc和ntl等背部标记基因的表达增强，但eve1等腹部标记基因的表达减弱。

The wing is a flattened evagination of the dorsal body wall.

翅是昆虫背板的片状翻出物。

Recently, nerve control was thought to be very important in the control of pancreatic exocrine secretion, especially vagus and dorsal motor nucleus.

而在胰腺外分泌的神经调控中，迷走神经和迷走神经背核起到了重要的作用，因此本项研究主要就针对这二者进行胰腺外分泌的神经传递机制的研究。

Genetic diversity and phylogenetic relationship in goldfish were examined using mitochondrial D-Loop partial sequences at eight representative varieties of goldfishes and wild crucian carp. The eight representative varieties were Red Common Goldfish, Red Fantail, White Oranda with Red Carp, White Pearlscale, Red Tigerhead, Black Moor, Red Moor with Butterfly Tail and Red Bubble-eye with Dorsal Fin. 699 base-pair nucleotide sequences of Mitochondrial D-Loop were examined and analyzed for genetic polymorphism, Sequences data showed that all 129 sequences were grouped into 17 haplotypes. Nine representative varieties shared same haplotype. Five representative varieties of goldfishes had haplotypes respectively.

采用PCR技术扩增了红草金鱼，红文鱼，红顶白高头，白珍珠，红狮头，红龙睛蝶尾，墨龙睛，红水泡八个品种金鱼和野生鲫线粒体DNA的D-Loop区部分序列，PCR产物经纯化、测序、同源序列比对后获得长度为699bp的核苷酸序列，在129个样本中共检测到了17个单倍型，9个品种共享1种单倍型，5个品种的金鱼(BM， MB， WR， RF， RC)检测到各自独有的单倍型。

In dorsal roots, Agamma fibers represented approximately 70% of all nerve fibers in every root and fascicle.

在后根，Aγ纤维约占每个神经根和束所有神经纤维的70%。

The palmar part and dorsal part mainly composed of compact connective tissue and fibrocartilage were found in proximal part.
