查询词典 dorsoventral

Based on the study in Lotus japonicus, a model legume plant in Papilionoideae, scientific groups led by Luo Da demonstrated that TCP proteins have been independently recruited as determinants of petal identities along the dorsoventral axis in two distant lineages of flowering plants Antirrhinum majus and Lotus japonicus, suggesting a synapomorphic origin for the mechanisms in the control of floral zygomorphy.

以蝶型花亚科的百脉根为研究对象，罗达等研究组阐明了在豆科与其他物种基因组中调控花对称性发育的分子机制具有共源性，揭示了在高等植物花形进化过程中，不同进化关系的开花植物独立地招募TCP基因，调控了两侧对称花发育过程中背腹轴的发育。

In addition, the South Korean researchers identified the maintenance of embryonic stem cells pluripotent Rap2GTPase gene in control of vertebrate dorsoventral axis structure of Nodal signal-regulated protein in the process of mechanism.

此外，韩国研究者查明了维持胚胎干细胞多能性的Rap2GTPase基因在控制脊椎动物背腹轴结构形成的Nodal蛋白质信号调节过程中的作用机理。

Over 3000 years ago, however, the ancient bronze designers of Sanxingdui constructed human eyes in a "mosaic" both dorsoventral and nasotemporal divisions.

西方学者在19世纪提出了眼睛的&拼合&模型，当今发育生物学、遗传学以及分子细胞生物学研究结果进一步证明了该模型的合理性。

There were 42 patients with dorsoventral pain before the therapy. 27 patients(64.3%) got complete recover, 12 ( 28.6%)pain remission, and 3(7.1%) ineffective. The analgesic effective rate was 92.9%.

42例治疗前伴腹背部疼痛，完全消失27例（64.3%），疼痛缓解12例（28.6%），3例无效（7.1%），止痛有效率为92.9%。

The dorsoventral movement of the tail produces the thrust, and bending of the anterior body in the horizontal plane enables turning maneuvers.

用一个串联的、多关节的上下摆动机构来实现背腹式运动，用左右摆动的转弯机构和两自由度运动的鳍肢机构来实现机动运动。

Analysis of PcG mutants shows that the PcG system represses genes required for anteroposterior, dorsoventral, and proximodistal patterning of imaginal discs and that it also represses cell cycle regulator genes.

对PcG突变体研究发现，PcG系统表达基因在幼虫发育的前端、背腹以及远端模式都是必须的，同时可抑制细胞分裂调节基因的活性。

We propose that the noncell-autonomous effects of Spemann's organizer on dorsoventral patterning are executed in part by diffusible signals that directly bind to and neutralize ventral BMPs during gastrulation.

我们提出，施佩曼组织器对背腹式的非细胞自发功能，有部分是通过原肠胚形成过程中，直接结合和抵消腹部BMP的扩散性信号所发挥的。

Furthermore, knockdown of Hspa5 rescues ventralized phenotypes induced by overexpression of Bmp2b; on the other hand, dorsalized phenotypes caused by Hspa5 knockdown disappear when Bmp2b mRNA is coinjected. It is likely that involvement of Hspa5 in dorsoventral patterning is associated with Bmp signals.

进一步研究发现，抑制Hspa5的表达能够挽救Bmp2b过量表达所导致的胚胎腹部化，Bmp2b的过量表达可使阻断Hspa5表达所引起的背部化表型减弱，提示Hspa5在胚胎背腹分化方面的作用可能与Bmp信号相关。

In the most caudal extent of the striatum, there was also a dense band of CGRP-positive fibers in the lateral border of the caudate putamen and the direction of the fibers was also dorsoventral. There are some transverse CGRP-positive fibers connecting the MrD and Cpu.

CGRP免疫阳性纤维分布越靠纹状体尾，则纤维越密集，且阳性带越宽；（2）在纹状体的最尾侧，除边缘区外，尾壳核的外侧缘也出现一条致密的阳性纤维带，与边缘区走向一致。

Using the distortion-compensated roentgen analysis method, disc height, dorsoventral displacement, and lordosis were measured in 212 unfused segments from 62 patients, on digitized standing radiographs taken before fusion surgery and after a mean follow-up of 7.5 years (range, 4-11 years).

在标准数字化X光片上，比较术前和术后平均7.5年（4－11年）后62个病人212个未融合节段的椎间盘高度、椎体滑脱及脊柱前凸的情况，可变的影响因素如年齡、随访时间的长度、融合水平、融合节段数、融合节段上下方向和手术前后椎管的改变，用重复测量模型进行分析。
