胚胎发育

Metanephric adenoma is a unique renal tumor with benign biologic behaior in spite of their large size.

后肾腺瘤尽管体积较大，但却为胚胎发育过程中后肾来源的良性肿瘤，较少见。

In recent years, reconstruction of the auricle for the patient with microtia has been developmenting rapidly in China, but the relationship between ear and jaw defects in syndromic patterns of malformation cannot be found in Chinese literature.

外耳、中耳和面部的多数结构由第一、第二鳃弓衍化而来，因此，由于胚胎发育上的同源性，小耳畸形常与颌面部畸形同时存在。尽管人们对这种关系的认识由来已久，但至今大多数临床学家仍把小耳畸形看作为一个单一的畸形来处理。

He gave accurate descriptions of ruminants' four-chambered fore-stomachs, and of the ovoviviparous embryological development of the hound shark Mustelus mustelus.

他准确描述了反刍动物的四腔前胃，以及猎鲨--星鲨卵的胚胎发育。

I don't think this is clear cell meningioma, chordoma, central neurocytoma, hemangioblastoma, oligodendroglioma, ependymoma or DNET.

我不考虑透明细胞型脑膜瘤、脊索瘤、中枢神经细胞瘤、血管母细胞瘤、少突胶质细胞瘤、室管膜瘤或胚胎发育障碍的神经上皮肿瘤。

Objective To discuss the diagnosis and treatment for dysembryoplastic neuroepithelial tumor.

目的 探讨胚胎发育不良性神经上皮瘤的诊断和治疗。

Objective: To investigate the clinical, radiological, pathological characteristics, diagnosis and differential diagnosis of dysembryoplastic neuroepithelial tumor.

目的：探讨胚胎发育不良性神经上皮肿瘤的临床、影像及病理学特征、诊断及鉴别诊断。

Results: The findings on CT and MRI were as follows: 57 cases of Oligodendroglioma, 15 cases of Ganglioglioma , 5 cases of Dysembryoplastic neuroepithelial tumor , 3 cases of Pleomorphic xanthoastrocytoma .

结果：少枝胶质瘤47例，间变性少枝胶质瘤10例，节细胞胶质瘤15例，胚胎发育不良性神经上皮瘤5例，多形黄色细胞瘤3例。

I think WHO grade I dysembryoplastic neuroepithelial tumor is the most likely diagnosis, but one would like to see isolated floating neurons in the microcysts in addition to the small oligodendrocyte-like cells and neuropil-like fibrillary matrix.

我考虑可能是WHOI级的DNT（胚胎发育障碍的神经上皮肿瘤）。但DNT中除了少突胶质细胞样的小细胞和神经毡样胶质纤维基质外，还应该见到微囊中漂浮的神经元。

TGFβ/Nodal signaling pathway is one of the most important signaling pathways in the development of embryos.

TGFβ/Nodal信号通路是影响胚胎发育的几个重要的信号通路之一。

These data give some new insights on the mechanism of TGFβ/Nodal transduction and in regulation of embryonic development.

这些数据为了解TGFβ/Nodal信号的转导调控机理和对胚胎发育的调控作用提供了新的视觉。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
