The present study analyzed the influence of 3-[3-（3-florophenyl-2-propyn-l-ylthio）-1, 2, 5-thiadiazol-4-yl]-1, 2, 5, 6-tetrahydro-l-methylpyridine oxalate （EUK1001）, a novel xanomeline derivative of the M1/M4 receptor agonist, on hippocampal neurogenesis in adult C57BL6 mice. Results showed that 15-day EUK1001 treatment via intraperitoneal injection promoted neural cell proliferation in the dentate gyrus, although cell differentiation did not change. The majority of bromodeoxyuridine-positive cells co-expressed the immature neuronal marker doublecortin. In addition, the level of neurogenesis in the subventricular zone was not altered. Brain-derived neurotrophic factor mRNA expression was up-regulated following EUK1001 treatment, but no change was observed in expression of camp-responsive element binding protein 1, paired box gene 6, vascular endothelial growth factor alpha, neurogenic differentiation factor 1, and wingless-related mouse mammary tumor virus integration site 3A mRNA. These experimental findings indicated that EUK1001 enhanced proliferation and survival of hippocampal cells, possibly by increasing brain-derived neurotrophic factor expression.

采用增材制造(additive anufacturing,AM)技术制备了钛合金点阵夹芯梁,使用硅橡胶作为阻尼材料对点阵空隙进行了填充。测试对比了有/无填充的点阵夹芯悬臂梁的模态振型,并对其进行了扫频振动激励。试验结果表明:填充阻尼材料不会改变结构振型,但可显著降低振动响应幅值。开展了硅橡胶的动态力学分析试验(dynamic mechanical analysis,DMA),结合广义麦克斯韦(generalized Maxwell model,GMM)粘弹性模型,标定了频域粘弹性模型参数。通过硅橡胶单轴拉伸试验标定了多项式型超弹性模型参数。基于粘超弹性模型及标定参数,对有填充的点阵夹芯悬臂梁进行了振动响应有限元模拟,与试验结果相符,证明本文采用的粘超弹性模型和其参数标定方法可有效用于混合结构的振动特性计算。

Luminescent materials exhibiting emission switching in the solid state have drawn much attention though there is still no clear design strategy for such materials. In this letter, we reported the crystallization induced emission enhancement (CIEE) of di(4-ethoxyphenyl)dibenzofulvene (1), and achieved switching its emission among four different colors through modulation of its molecular packing patterns. We have investigated its potential application as optical recording materials. The twisted conformations of CIEE compounds afford morphology dependent emission and facilitate tuning their emission through modulation of molecular packing patterns. Thus we provide a possible design strategy for solid stimulus responsive luminescent materials.
