| 1 | 制备碳化钨功能梯度材料的液相迁移和方式的评述显示文摘自从WC-Co(FG WC-Co)梯度功能材料得到优异的耐磨性、断裂韧性和强度的组合,也提供了优异的工程性能,都超过了传统的均匀WC-Co材料。已经开发了许多生产FG WC-Co的工艺,其中几种已商品化。但是关于在WC-Co中如何形成梯度结构的基本原理在理解上还有相当大的分歧。根据最近大部分的研究,本文的作者们检验了制备FG WC-Co的工艺,发现大部分情况是通过液相迁移达到WC-Co中形成梯度结构,可用不同的技术诱发迁移。评述了几种有代表性的FG WC-Co工艺,并用液相迁移理论作解释。一种新工艺是用全烧结WC-Co渗碳来诱发液相迁移。 | Peng Fan Fang Z Z Guo Jun | 2013 | 热处理技术与装备2013，34，6： | 4 |
| 2 | Differentiation renders susceptibility to excitotoxicity in HT22 neurons显示文摘HT22 is an immortalized mouse hippocampal neuronal cell line that does not express cholinergic and glutamate receptors like mature hippocampal neurons in vivo.This in part prevents its use as a model for mature hippocampal neurons in memory-related studies.We now report that HT22 cells were appropriately induced to differentiate and possess properties similar to those of mature hippocampal neurons in vivo,such as becoming more glutamate-receptive and excitatory.Results showed that sensitivity of HT22 cells to glutamate-induced toxicity changed dramatically when comparing undifferentiated with differentiated cells,with the half-effective concentration for differentiated cells reducing approximately two orders of magnitude.Moreover,glutamate-induced toxicity in differentiated cells,but not undifferentiated cells,was inhibited by the N-methyl-Daspartate receptor antagonists MK-801 and memantine.Evidently,differentiated HT22 cells expressed N-methyl-D-aspartate receptors,while undifferentiated cells did not.Our experimental findings indicated that differentiation is important for immortalized cell lines to render post-mitotic neuronal properties,and that differentiated HT22 neurons represent a better model of hippocampal neurons than undifferentiated cells. | Minchao He Jun Liu haowu Cheng Yigang Xing William Z Suo | 2013 | Neural Regeneration Research2013，8，14： | 3 |
| 3 | 贝尔麻痹影响大脑默认模式网络的功能连接(英文)显示文摘目的贝尔麻痹是一种常见的特发性面神经病变,导致病变侧的面部肌肉运动功能丧失。作者探讨了贝尔麻痹对大脑默认模式网络(DMN)功能连接的影响。材料与方法使用1.5 T MR成像仪获取静息态f MRI数据,包括健康志愿者35名及不同病理状态下的面瘫患者52例次。使用双重回归独立成分分析方法处理数据。结果发现面瘫不同病理状态下DMN的功能连接发生了不同的变化。在面瘫疾病早期,DMN功能连接在右侧初级感觉皮层、初级运动皮层、背外侧前额叶显著增强;在面瘫后期,DMN功能连接在双侧中扣带回、楔前叶、右侧富内侧前额叶、后扣带回显著增强;在面瘫康复后,DMN功能连接在左侧舌回、小脑显著增强。结论在面瘫不同病理阶段,DMN的功能连接存在着明显的不同,涉及到感觉运动,运动映射,情感以及认知等不同功能脑区。 | Abdalla Z Mohamed Chuanfu Li Jeungchan Lee Seulgi Eun Yifang Zhu Yuanyuan Wu Jun Yang Kyungmo Park | 2014 | 磁共振成像2014，5，6： | 2 |
