1Solar thermotherapy reduces the titer of Candidatus Liberibacter asiaticus and enhances canopy growth by altering gene expression profiles in HLB-affected citrus plants显示文摘Huanglongbing(HLB),a systemic and destructive disease of citrus,is associated with‘Candidatus Liberibacter asiaticus’(Las)in the United States.Our earlier work has shown that Las bacteria were significantly reduced or eliminated when potted HLB-affected citrus were continuously exposed to high temperatures of 40 to 42°C for a minimum of 48 h.To determine the feasibility and effectiveness of solar thermotherapy in the field,portable plastic enclosures were placed over commercial and residential citrus,exposing trees to high temperatures through solarization.Within 3–6 weeks after treatment,most trees responded with vigorous new growth.Las titer in new growth was greatly reduced for 18–36 months after treatment.Unlike with potted trees,exposure to high heat did not eradicate the Las population under field conditions.This may be attributed to reduced temperatures at night in the field compared to continuous high temperature exposure that can be maintained in growth chambers,and the failure to achieve therapeutic temperatures in the root zone.Despite the presence of Las in heat-treated commercial citrus,many trees produced abundant flush and grew vigorously for 2 to 3 years after treatment.Transcriptome analysis comparing healthy trees to HLB-affected citrus both before and after heat treatment demonstrated that post-treatment transcriptional expression patterns more closely resembled the expression patterns of healthy controls for most differentially expressed genes and that genes involved with plant-bacterium interactions are upregulated after heat treatment.Overall,these results indicate that solar thermotherapy can be an effective component of an integrated control strategy for citrus HLB.Melissa M Doud Yungsheng Wang Michelle T Hoffman Christina L Latza Weiqi Luo Cheryl M Armstrong Tim R Gottwald Liangying Dai Feng Luo Yongping Duan 2017Horticulture Research2017,4,1:1

5THE RESEARCH ON MECHANISMS OF AMYLOID- β PROTEIN INDUCING ALZHEIMER'S DISEASE IN RAT AND EFFECTS OF NIMODIPINE TREATMENT显示文摘0bjective In order to clarify the mechanism of the neurotoxics of Aβ, we studied the effects on the rCBF, extra-cellular amino acid (EAA), apoptosis and Bcl-2 protein expression, and their relationship with learning and memory deficiency. Methods Aβ was injected into NBM in rats to establish the AD model, learning and memory abilities were observed by Y-maze. The rCBF was measured by hydrogen clearance method. The EAA was detected by microdialysis in vivo with HPLC. The apoptosis and Bc1-2 protein expression was examined by flow cytometry. The male SD rats were divided into three groups: the model group was injected Aβ (10 μ g) into NBM of the rat. The control group was injected NaC1 (0.9%) in the same way. The treatment group was made with intraperitoneal injections of Nimodipine for 2 weeks after A β injections. Results The administration of Aβ into rat′s NBM could lead to the loss of learning and memory abilities. It was found that in frontal cortex and hippocampus, the rCBF decrease, however, with no trend of progressive decline. On the other hand, the levels of EAA increased, especially glutamate. Furthermore, A β significantly induced neurons apoptosis of frontal cortex and hippocampi cell, and upregulated the expression of the bcl-2. The Nimodipine might entirely improve rCBF of AD rats nearly to normal level, lessen the release of EAA and augment restrain neurotransmission. It might reduce the apoptosis partly, but it couldn't improve the learning and memory disorders completely. Conclusion The results implied that the neurotoxic effect of Aβ exists multi-mechanism.Chunfeng Liu Shiyao Bao Yongping Dai 2000中国临床神经科学2000,8,z1:0
6Ge Film Contacts to Radio Frequency Sputtered Y-Ba-Cu-O Superconductor Film显示文摘The semiconductor-superconductor con tact system of Ge/Y-Ba-Cu-O(YBCO)/SrTiO_(3) has been successfully fabricated by two steps of deposition.The YBCO film in the contact of Ge/YBCO did not lose its superconductivity and its T_(c)(on set)did not degrade as well.The top layer of Ge was polycrystalline with preferred orientation corresponding to the epitaxial structure of the underlayer of YBCO.ZHANG Bei QIAN Yi TONG Litai CHEN Haiying WANG Guizhi QIAO Yongping XING Miaoxiang FENG Qingrong LIU Zunxiao LAN Jian DAI Yuandong 1991Chinese Physics Letters1991,8,9:0
7Advances in Mathematical Modeling of NFκB Signal Transduction in Mammals显示文摘NFκB is a basic transcription factor of cell signal transduction in mammals. Mathematical modeling can be used to simulate NFκB signal transduction and investigate the molecular mechanism. The initial IκB-NFκB signal transduction model emphasized the effects of negative feedback on NFκB temporal dynamics and gene expression control,while subsequent studies are concentrated on other feedback loops,input-output behaviors of modules,crosslinking of several NFκB activation paths and NFκB oscillation. Computer technology will continue to contribute to studies of NFκB signaling pathway. Finally,several potential development trends were discussed in this paper.Jinshan ZHAO Ke JIANG Zhenghao DAI Xiaoli REN Yumei WANG Yongping JIANG Mingtuan LIU Yonglian DAI Lele HOU Hegang LI 2013Agricultural Biotechnology2013,2,4:0
8An inexact risk management model for agricultural land-use planning under water shortage显示文摘水资源可获得性在农业陆地使用计划上有重要影响,特别在象诺思中国那样的一个水缺乏区域。在在场的一个农业系统的可得到的水资源和另外的无常的随机的性质为计划的陆地使用冒险并且可以导致不受欢迎的决定或潜在的经济损失。在这研究,一个不精确的风险管理模型(IRM ) 为支持农业陆地使用在水缺乏下面计划和风险分析被开发。IRM 模型通过合并有条件的 value-at-risk (CVaR ) 被提出限制进不精确的二阶段的随机的编程(ITSP ) 框架,并且能被用来控制表示为不仅概率分布而且同样分离的间隔的无常。关于秒阶段惩罚费用的风险的措施被合并到模型以便在系统利益和极端期望的损失之间的交易能被分析。发达模型在 Zhangweinan 河盆被用于案例研究,在诺思中国面对严肃的水缺乏的一个典型农业区域。IRM 模型的解决方案证明获得的第一阶段的陆地使用目标值能被用来在长期的开发计划上反映决策人意见。信心水平和最大的可接受的风险损失能被用来向系统利益和风险控制反映 decisionmakers 偏爱。结果显示 IRM 模型为向风险厌恶反映决策人态度是有用的并且能帮助寻求在复杂无常下面计划策略的划算的农业陆地使用。Wei LI Changchun FENG Chao DAI Yongping LI Chunhui LI Ming LIU 2016Frontiers of Earth Science2016,10,3:0
