| 1 | Crystallization Behavior and Kinetics of Lithium Aluminosilicate Glasses with Various Li_(2)O Contents显示文摘The crystallization behavior of Li_(2)O-Al_(2)O_(3)-SiO_(2) glasses with various concentration of Li2O were investigated by DSC,XRD,and FE-SEM.The h/l-quartz s.s.is the main crystalline phase for all of the glass with the heat treatment of 720℃/3 h+800℃/1.5 h while the crystallinity and crystal size increase with the increase of Li2O contents.Due to the negative thermal expansion coefficient of h/l-quartz s.s.,the thermal expansion coefficient of glass-ceramics decreases with the increasing of Li2O contents.When the Li2O content is 9mol%,the near-zero CTE20-700℃=-0.09×10^(-6)℃^(-1) is obtained upon the heat treatment of 720℃/3 h+800℃/1.5 h.The crystallization activation energy of the glass with 9mol%Li2O is about 351 kJ/mol,and the crystallization mechanism is volume crystallization. | 韩建军 HONG Wei 姜宏 HE Jianxiong WANG Qianchen WANG Jing GAO Wenkai | 2021 | Journal of Wuhan University of Technology(Materials Science)2021，36，2： | 3 |
| 2 | Pilose antler polypeptides ameliorates hypoxic- ischemic encephalopathy by activated neurotrophic factors and SDF1/CXCR4 axis in rats显示文摘Hypoxic-ischemic encephalopathy (催促) 是与高死亡和病态被联系的一个复杂条件。然而,很少有希望的处理为催促存在。在现在的学习,中央目的是识别覆有毛的鹿角多肽(奶头) 的治疗学的效果在上在老鼠催促。Sprague-Dawley (SD ) 老鼠(14 天旧) 被使用并且把组划分了成三包括控制组, hypoxic 局部缺血(嗨) 组和奶头组。在 21 天处理以后,运动活动在对待奶头的老鼠被改进,大脑萎缩被减少,服的浮肿被减轻到某程度。实时量的聚合酶链反应(RT-qPCR ) 分析显示奶头管理减少了在马头鱼尾的怪兽的煽动性的 cytokines 和 apoptosis 基因的表情与相比嗨组。而且,与神经营养的因素有关的基因的 mRNA 表情显著地在马头鱼尾的怪兽被增加。另外,氧化压力标记的表情都在奶头管理以后是下面调整的。而且,奶头起来调整 mRNA 和 SDF1 和 CXCR4 的蛋白质层次,它可以激活 SDF1/CXCR4 轴到节制大脑损害。这些结果建议那个奶头可以潜在地在处理被使用催促。 | Tao Wu Luna Yang Yan Chen Yinhua Ni Jianguo Jiang Wanjing Zhang Qianchen Zhou Xiaojun Zheng Qi Wang Zhengwei Fu Haifeng Li | 2018 | Acta Biochimica et Biophysica Sinica2018，50，3： | 3 |
| 3 | Osseous Rosai-Dorfman disease of tibia in children:A case report显示文摘BACKGROUND Rosai-Dorfman disease(RDD),or sinus histiocytosis with massive lymphadenopathy,is a benign histiocytic disorder.Extranodal involvement is common,occurring in>40%of patients,but bone involvement occurs in<10%of cases.In addition,primary bone RDD is extremely rare.The majority of patients are adolescents and young adults,and the mean age at onset is 20-years-old.CASE SUMMARY We report an 8-year-old Chinese girl who presented to our hospital with an insidious onset of swelling and pain in the middle shaft of her right tibia for 4 mo.We performed total surgical resection of the right tibia lesion and allograft transplantation.A good prognosis was confirmed at the 6 mo follow-up.Pain and swelling symptoms were totally relieved,range of motion of her right knee and ankle returned to normal,and there was no clinical evidence of lesion recurrence at last follow up.Our case is the second reported case of osseous RDD without lymphadenopathy in the shaft of the tibia of a child.CONCLUSION Extranodal RDD is a rare disease and can be misdiagnosed easily.Lesion resection and allograft transplantation are an option to treat extranodal RDD in children with good short term result.Pediatric orthopedist should be aware of this rare disease,especially extranodal involvement. | Djandan Tadum Arthur Vithran Jian-Zhou Wang Feng Xiang Jie Wen Sheng Xiao Wen-Zhong Tang QianChen | 2021 | World Journal of Clinical Cases2021，9，6： | 1 |
| 4 | Estimating posterior inference quality of the relational infinite latent feature model for overlapping community detection显示文摘Overlapping community detection has become a very hot research topic in recent decades,and a plethora of methods have been proposed.But,a common challenge in many existing overlapping community detection approaches is that the number of communities K must be predefined manually.We propose a flexible nonparametric Bayesian generative model for count-value networks,which can allow K to increase as more and more data are encountered instead of to be fixed in advance.The Indian buffet process was used to model the community assignment matrix Z,and an uncol-lapsed Gibbs sampler has been derived.However,as the community assignment matrix Zis a structured multi-variable parameter,how to summarize the posterior inference results andestimate the inference quality about Z,is still a considerable challenge in the literature.In this paper,a graph convolutional neural network based graph classifier was utilized to help tosummarize the results and to estimate the inference qualityabout Z.We conduct extensive experiments on synthetic data and real data,and find that empirically,the traditional posterior summarization strategy is reliable. | Qianchen YU Zhiwen YU Zhu WANG Xiaofeng WANG Yongzhi WANG | 2020 | Frontiers of Computer Science2020，14，6： | 1 |
| 5 | The prospect and challenges of sodium-ion batteries for low-temperature conditions显示文摘In recent years,considerable attention has been focused on the development of sodium-ion batteries(SIBs)because of the natural abundance of raw materials and the possibility of low cost,which can alleviate the concerns of the limited lithium resources and the increasing cost of lithium-ion batteries.With the growing demand for reliable electric energy storage devices,requirements have been proposed to further increase the comprehensive performance of SIBs.Especially,the low-temperature tolerance has become an urgent technical obstacle in the practical application of SIBs,because the low operating temperature will lead to sluggish electrochemical reaction kinetics and unstable interfacial reactions,which will deteriorate the performance and even cause safety issues.On the basis of the charge-storage mechanism of SIBs,optimization of the composition and structure of electrolyte and electrode materials is crucial to building SIBs with high performance at low temperatures.In this review,the recent research progress and challenges were systematically summarized in terms of electrolytes and cathode and anode materials for SIBs operating at low temperatures.The typical full-cell configurations of SIBs at low temperatures were introduced to shed light on the fundamental research and the exploitation of SIBs with high performance for practical applications. | Meng Wang Qianchen Wang Xiangyu Ding Yingshuai Wang Yuhang Xin Preetam Singh Feng Wu Hongcai Gao | 2022 | Interdisciplinary Materials2022，1，3： | 1 |
| 6 | Prussian-blue materials:Revealing new opportunities for rechargeable batteries显示文摘The demand to increase energy density of rechargeable batteries for portable electronic devices and electric vehicles and to reduce the cost for grid-scale energy storage necessitates the exploration of new chemistries of electrode materials for rechargeable batteries.The open framework-structure of Prussian-blue materials has recently been demonstrated as a promising cathode host for a variety of monovalent and multivalent cations with the tunable working voltage and discharge capacities.Recent progress toward the application of Prussian-blue cathode materials for rechargeable batteries is reviewed,with special emphasis on charge-storage mechanisms of different insertion species,factors influencing electrochemical performances,and possible approaches to overcome their intrinsic limitations. | Qianchen Wang Jingbo Li Haibo Jin Sen Xin Hongcai Gao | 2022 | InfoMat2022，4，6： | 1 |
| 7 | FERM domain-containing protein FRMD6 activates the mTOR signaling pathway and promotes lung cancer progression显示文摘FRMD6,a member of the 4.1 ezrin-radixin-moesin domain-containing protein family,has been reported to inhibit tumor progression in multiple cancers.Here,we demonstrate the involvement of FRMD6 in lung cancer progression.We find that FRMD6 is overexpressed in lung cancer tissues relative to in normal lung tissues.In addition,the enhanced expression of FRMD6 is associated with poor outcomes in patients with lung squamous cell carcinoma(n=75,P=0.0054)and lung adenocarcinoma(n=94,P=0.0330).Cell migration and proliferation in vitro and tumor formation in vivo are promoted by FRMD6 but are suppressed by the depletion of FRMD6.Mechanistically,FRMD6 interacts and colocalizes with mTOR and S6K,which are the key molecules of the mTOR signaling pathway.FRMD6 markedly enhances the interaction between mTOR and S6K,subsequently increasing the levels of endogenous pS6K and downstream pS6 in lung cancer cells.Furthermore,knocking out FRMD6 inhibits the activation of the mTOR signaling pathway in Frmd6^(−/−)gene KO MEFs and mice.Altogether,our results show that FRMD6 contributes to lung cancer progression by activating the mTOR signaling pathway. | Tianzhuo Wang Huiying Guo Lei Zhang Miao Yu Qianchen Li Jing Zhang Yan Tang Hongquan Zhang Jun Zhan | 2023 | Frontiers of Medicine2023，17，4： | 0 |
