神经发生的

Efforts to develop engineered intestines are also proceeding, Dr. Vacanti said. Engineered esophagi, jejunums, and colons, grown on tubular degradable polymers, are showing angiogenesis and some neurogenesis. Motility is present although dysfunctional, Dr. Vacanti reported.

肠的制造也正在努力进行中，人工制造的食道、空肠及结肠，在管状的可生物分解聚合物上生长，已显示出血管及神经的发生，但是其蠕动性还未正常运作。

The rat hindlimb representation of S1 area is likely to have at least 2 patterns of neural circuits on brain slices: one is the intracortical circuit formed by interlaminar connections from layers II-III, and the other is the thalamocortical circuit mediated by afferent connections from layer IV.

相反，在II-III层，同样的强直刺激并未能明显诱导LTP的发生。结论大鼠S1区的后肢代表区似乎存在两种不同类型的神经回路，一种是由层间联系介导的皮层内回路，另一种则是由丘脑皮层传入介导的丘脑皮层连接回路。

Results: ApoD was observed positively expressed in type2 astrocytes and oligodendrocytes from O2A lineage, while it was not expressed in type1 astrocytes from T1A lineage. Accordingly, we can verify the phenomenon found in the study of T1A and T2A gene different expression profile that ApoD mRNA was highly expressed in T2A and lowly expressed in T1A. Conclusion: It can be concluded that lipid metabolism related genes such as ApoD play important roles in the generation and differentiation of O2A lineage, which closely correlate with internal mechanism of lipid metabolism in the brain and myelogenesis.［Key words］astrocyte(T1A, T2A); oligodendrocyte; O2A lineage; apolipoproteinApoD

我们已采用基因芯片技术在mRNA水平研究两型星形胶质细胞的基因表达谱差异，发现ApoD在2型星形胶质细胞中差异高表达，故本文拟用激光共聚焦双重免疫荧光标记技术进一步在蛋白质水平观察ApoD在体外分化成熟的两型星形胶质细胞以及少突胶质细胞中的表达情况，以期为我们深入研究ApoD等脂代谢相关基因在脑内脂质代谢和神经髓鞘发育机制中所起的作用提供有用的实验依据，依此探讨胶质细胞发生和分化的信号机制。

The aggregation of misfolded proteins becomes a threat to cell survival,and promotes pathogenesis of neurodegenerative diseases.

错误折叠蛋白质的聚集，对细胞的存活造成严重的威胁，促进神经退行性病变的发生。

Taken together, these findings suggest that Bmp-4, Shh and Wnt-5a gene expressions may act together on the epithelial-mesenchymal interactions occurring in several aspects of the early mouse craniofacial development, such as odontogenesis, neuronal development, maxillae and mandible ossification, palatogenesis and tongue formation.

综上所述，这些研究结果表明，骨形态发生蛋白4， Shh和Wnt信号- 5A型基因表达共同作用，对早期小鼠颅面部的发育中上皮间的相互作用产生很大影响，如牙齿的发育，神经发展，上颌骨和下颌骨骨化及舌头的形成。

Using 11C--PK11195 positron emission tomography, we investigated microglial activation in HD presymptomatic gene carriers, its relationship with striatal neuronal dysfunction measured with 11C-raclopride PET, and the role of PK PET as a possible marker of subclinical disease progression in PGCs. Eleven HD PGCs underwent PK and RAC PET. Their results were compared with those of healthy controls.

利用11C--PK11195电子发射断层扫描，我们研究了HD的基因携带者症状发生前小神经胶质细胞的活化情况，它与纹状体的神经元的机能障碍的关系，以及PET可能作为PGCs亚临床症状进展的指标。11位HDPGCs接受了PK和RACPET检查，其结果与健康对照人群进行比较。

Multivariable analysis found that cerebral infarction was significantly associated with increasing patient age,worse neurological grade on admission, history of hypertension or diabetes mellitus, larger aneurysm, use of prophylactically or therapeutically induced hypertension, temperature more than 38 degrees C 8 days after SAH, and symptomatic vasospasm.

多因素分析发现脑梗的发生与病人年龄增加、入院时较差的神经学分级、有高血压或糖尿病史、较大的动脉瘤、预防性或治疗性高血压的应用、SAH后8天体温高于38度和症状性血管痉挛显著相关。

多因素分析发现脑梗的发生与病人年龄增加、入院时较差的神经学分级、有高血压或糖尿病史、较大的动脉瘤、预防性或治疗性高血压的应用、SAH后8天体温高于38度和症状性血管痉挛显著相关。

The mechanism was to lead mandibular retrusion and accelerate forward growth of the maxillary.The relief of anterior crossbite combined with the retrusion of condylar and mandible led to the reconstruction of TMJ and nerve- muscles .

前牙反锁结的解除并结合将前伸的踝突、下颌诱导后退，使TMJ、神经肌肉及相关骨骼发生适应性改建，恢复并稳定于正常的关节位，有利于恢复和建立后牙的正常ICP。

Objective Machado-Joseph disease/Spinocerebellar ataxia type 3 (SCA3) is an autosomal dominant neurodegenerative disorder caused by an expansion of polyglutamine tract near the C-terminus of the MJD1 gene product, ataxin-3. The precise mechanism of the MJD/SCA3 pathogenesis remains unclear.

目的 马查多-约瑟夫病/脊髓小脑共济失调3型，是由 MJD1基因产物ataxin-3的C-末端的多聚谷氨酰胺发生重复扩展突变而引起的一种常染色体显性遗传的神经退行性疾病，目前它的发病机制还不清楚。
