Peripheral mitochondrial DNA as a neuroinflammatory biomarker for major depressive disorder

In the pathogenesis of major depressive disorder, chronic stress-related neuroinflammation hinders favorable prognosis and antidepressant response. Mitochondrial DNA may be an inflammatory trigger, after its release from stress-induced dysfunctional central nervous system mitochondria into peripheral circulation. This evidence supports the potential use of peripheral mitochondrial DNA as a neuroinflammatory biomarker for the diagnosis and treatment of major depressive disorder. Herein, we critically review the neuroinflammation theory in major depressive disorder, providing compelling evidence that mitochondrial DNA release acts as a critical biological substrate, and that it constitutes the neuroinflammatory disease pathway. After its release, mitochondrial DNA can be carried in the exosomes and transported to extracellular spaces in the central nervous system and peripheral circulation. Detectable exosomes render encaged mitochondrial DNA relatively stable. This mitochondrial DNA in peripheral circulation can thus be directly detected in clinical practice. These characteristics illustrate the potential for mitochondrial DNA to serve as an innovative clinical biomarker and molecular treatment target for major depressive disorder. This review also highlights the future potential value of clinical applications combining mitochondrial DNA with a panel of other biomarkers, to improve diagnostic precision in major depressive disorder.

Acta Metallurgica Sinica(English letters) 1999年第1期12卷 40-45页

作者： Shi, H.J. liu, S.l. He, Y.H. duan, Z.x. Tsinghua Univ Beijing China

A series of low cycle fatigue and creepfatigue tests on smooth specimens and notched specimens were performed with a high temperature alloy used in the manufacture of aeroengine turbine discs. The cyclic stressstrain behavior and fracture characteristics of the notched specimens were emphatically investigated. A comparison of fatigue behavior between smooth and notched specimens was done and lifetime of notched specimens was evaluated. At the same temperature, the fatiguecreep lives of the smooth specimens are far greater than that of the notched specimens.

具有独特结构的纳米粒子在高分子材料领域具有广泛的应用.本文采用耗散粒子动力学模型系统的研究了三臂星形AB二嵌段共聚物和A均聚物共混体系的共组装相行为.通过调节聚集体中星形共聚物浓度和AB嵌段的长度比有效地控制了AB/A共混体系中聚集体的共组装形貌.预测了一些有趣的结构,比如,具有较厚壳层的核-壳-补丁结构、具有壳层的且中心凹陷的圆盘状结构以及不规则椭球的多室结构.本文还发现对于具有较长A嵌段的星形链,增大A均聚物在聚集体中的浓度能够消除聚集体内B嵌段形成的核;对于具有较短A嵌段的星形链,少量的A均聚物能够诱导聚集体共组装成具有长条状核的多室纳米粒子.

面部神经麻痹（Facial nerve paralysis,FNP），通常称为贝尔氏麻痹或面瘫，对患者的日常生活和心理健康产生显著影响，面瘫的及时识别和诊断对于患者的早期治疗和康复至关重要.随着深度学习和计算机视觉技术的快速发展，面瘫的自动识别变得可行，为诊断提供了一种更准确和客观的方式.目前的研究主要集中关注面部的整体变化，而忽略了面部细节的重要性.面部不同部位对识别结果的影响力并不相同，这些研究尚未对面部各个区域进行细致区分和分析.本项研究引入结合Vision transformer(ViT)模型和动作单元（Action unit,AU）区域检测网络的创新性方法用于面瘫的自动识别及区域分析.ViT模型通过自注意力机制精准识别是否面瘫，同时，基于AU的策略从StyleGAN2模型提取的特征图中，利用金字塔卷积神经网络分析受影响区域.这一综合方法在YouTube Facial Palsy(YFP)和经过扩展的Cohn Kanade(CK+)数据集上的实验中分别达到99.4%的面瘫识别准确率和81.36%的面瘫区域识别准确率.通过与最新方法的对比，实验结果展示了所提的自动面瘫识别方法的有效性.
