1Evolution of Sedimentation and Tectonics of the Youjiang Composite Basin, South China显示文摘Located at the southern margin of the South China plate, the Youjiang basin is a closely related to the NW- and NE-trending syndepositional faults in respect to the configuration and structure of the basin. The evolution of the Youjiang basin progressed through two stages. In the Hercynian period, the opening of the Ailaoshan-Honghe ocean basin gave rise to a number of NW-trending rift belts in the Youjiang area. During this period, deep-water sediments were dominant and the basin was possesed of the characteristics of the rift system of passive continental margins. In the early Indosinian after the Dongwu movement, the circum - Pacific tectonism led to a major change in the configuration and structure of the basin. In the meantime, the Ailaoshan ocean basin began to be subducted towards the northeast, thus causing the basin to be split and expand again, and then the basin developed into the stage of the back -arc basin. At the end of the Indosinian period, the basin gradually closed from east to west,Zeng Yunfu, Liu Wenjun, Cheng Hongde, Zheng Rongcai, Zhang Jinquan Chengdu Institute of Technology, Chengdu, SichuanLi Xiaoquan and Jiang Tingcao Regional Geological Survey Party of Guangxi,Guilin,Guangxi Jiang M inxi 1995Acta Geologica Sinica(English Edition)1995,69,4:18
2功能的限制的积极选择而非松驰在鸡驯服期间驾驶视觉的进化显示文摘是由达尔文,注意了鸡有所有鸟,而是国内鸡和他们的野祖先之间的有趣的进化差别的最大的 phenotypic 差异,红 Junglefowl,是他们的比较地更弱的视觉。存在理论建议在国内鸡之中的减少的视觉英勇反映功能的限制的松驰在识别负责的内在的基因机制的视觉,而是证据上驾驶的变化因为这个变化决定性地没被描绘。这里,国内鸡的染色体宽的分析和红 Junglefowl 染色体为涉及视觉的发展的断然选择的基因显示出重要丰富。关于为在视网膜的这些基因的 mRNA 表示的水平国内鸡和他们的野祖先之间有重要差别。涉及视觉的发展的众多的另外的基因也在在国内鸡和他们的野祖先之间的 mRNA 表示显示出重要差别,特别地为与 phototransduction 和光敏电阻器开发联系的基因,例如 RHO (视紫红质) , GUCA1A, PDE6B 和 NR2E3。最后,我们在视觉描绘了 VIT 基因的潜在的角色,它在村庄鸡的视网膜经历了积极选择和 downregulated 表示。总的来说,我们的结果建议净化选择的那种积极选择,而非松驰,在国内鸡贡献了视觉的进化。怀有更弱的视觉的国内鸡的祖先可能显示出减少的害怕回答和警戒,使他们更安逸无意识地被选择或驯养。Ming-Shan Wang Rong-wei Zhang Ling-Yan Su Yah Li Min-Sheng Peng He-Qun Liu Lin Zeng David M Irwin Jiu-Lin Du Yong-Gang Yao Dong-Dong Wu Ya-Ping Zhang 2016Cell Research2016,26,5:15
3Convergent genomic signatures of high-altitude adaptation among domestic mammals显示文摘Abundant and diverse domestic mammals living on the Tibetan Plateau provide useful materials for investigating adaptive evolution and genetic convergence.Here,we used 327 genomes from horses,sheep,goats,cattle,pigs and dogs living at both high and low altitudes,including 73 genomes generated for this study,to disentangle the genetic mechanisms underlying local adaptation of domestic mammals.Although molecular convergence is comparatively rare at the DNA sequence level,we found convergent signature of positive selection at the gene level,particularly the EPAS1 gene in these Tibetan domestic mammals.We also reported a potential function in response to hypoxia for the gene C10 orf67,which underwent positive selection in three of the domestic mammals.Our data provide an insight into adaptive evolution of high-altitude domestic mammals,and should facilitate the search for additional novel genes involved in the hypoxia response pathway.Dong-Dong Wu Cui-Ping Yang Ming-Shan Wang Kun-Zhe Dong Da-Wei Yan Zi-Qian Hao Song-Qing Fan Shu-Zhou Chu Qiu-Shuo Shen Li-Ping Jiang Yan Li Lin Zeng He-Qun Liu Hai-Bing Xie Yun-Fei Ma Xiao-Yan Kong Shu-Li Yang Xin-Xing Dong Ali Esmailizadeh David M Irwin Xiao Xiao Ming Li Yang Dong Wen Wang Peng Shi Hai-Peng Li Yue-Hui Ma Xiao Gou Yong-Bin Chen Ya-Ping Zhang 2020National Science Review2020,7,6:7
4Age and menopausal status are important factors influencing the serum human epididymis secretory protein 4 level:a prospective cross-sectional study in healthy Chinese people显示文摘Background::Human epididymis secretory protein 4(HE4)is a new ovarian cancer biomarker.The factors influencing HE4 levels are not clear,and the reference data in China are limited.Here,we aim to evaluate the effects of menopause and age on HE4 levels and to provide a possible reference value for HE4 in healthy Chinese people.Methods::A total of 2493 healthy females aged 40 years or older were recruited from March 2013 to March 2017 with the cooperation of four medical institutions across Beijing,China.The serum levels of HE4 and cancer antigen 125(CA125)were measured by enzyme-linked immunosorbent assay.The Wilcoxon rank-sum test of variance and a stratified analysis were used to analyze the relationships among age,menopausal status,and levels of HE4 or CA125.Confidence intervals(5%-95%)were determined for reference ranges in different populations.Results::There was a statistically significant difference in median HE4 levels between the post-menopausal(n=2168)and premenopausal groups(n=325)(36.46 vs.24.04 pmol/L,Z=-14.41,P<0.001).HE4 increased significantly with age in the post-menopausal groups(H=408.18,P<0.001)but not in the pre-menopausal subjects(Z=-0.43,P=0.67).The upper 95th percentile of HE4 levels were 44.63 pmol/L for pre-menopausal women,78.17 pmol/L for post-menopausal women,and 73.3 pmol/L for all women.In the post-menopausal population,the HE4 reference ranges were 13.15 to 47.31,14.31 to 58.04,17.06 to 73.51,24.50 to 115.25,and 35.71 to 212.37 pmol/L for different age groups from forty divided by decade.The CA125 level was affected mainly by menopausal status and not age.Conclusions::Menopausal status and age were both important factors influencing the level of HE4,and age affected HE4 levels mainly in post-menopausal women.The HE4 level was higher in the post-menopausal population than in the pre-menopausal population and increased with age.Hong-Yan Cheng Lin Zeng Xue Ye Rui-Qiong M a Zhi-Jian Tang Hong-Ling Chu Yi-M ing Zhao Li-Rong Zhu Yu-Nong Gao Xiao-Hong Chang Heng Cui 2020Chinese Medical Journal2020,,11:6

7Utilization of Thermal Infrared Image for Inversion of Winter Wheat Yield and Biomass显示文摘The present paper utilizes thermal infrared image for inversion of winter wheat yield and biomass with different technology of irrigation(drip irrigation,sprinkler irrigation,flood irrigation).It is the first time that thermal infrared image is used for predicting the winter wheat yield and biomass.The temperature of crop and background was measured by thermal infrared image.It is necessary to get the crop background separation index(CBSIL,CBSIH),which can be used for distinguishing the crop value from the image.CBSIL and CBSIH(the temperature when the leaves are wet adequately;the temperature when the stomata of leaf is closed completely) are the threshold values.The temperature of crop ranged from CBSIL to CBSIH.Then the ICWSI was calculated based on relevant theoretical method.The value of stomata leaf has strong negative correlation with ICWSI proving the reliable value of ICWSI.In order to construct the high accuracy simulation model,the samples were divided into two parts.One was used for constructing the simulation model,the other for checking the accuracy of the model.Such result of the model was concluded as:(1) As for the simulation model of soil moisture,the correlation coefficient(R2) is larger than 0.887 6,the average of relative error(Er) ranges from 13.33% to 16.88%;(2) As for the simulation model of winter wheat yield,drip irrigation(0.887 6,16.89%,-0.12),sprinkler irrigation(0.970 0,14.85%,-0.12),flood irrigation(0.969 0,18.87%,0.18),with the values of R2,Er and CRM listed in the parentheses followed by the individual term.(3) As for winter wheat biomass,drip irrigation(0.980 0,13.70%,0.13),sprinkler irrigation(0.95,13.15%,-0.14),flood irrigation(0.970 0,14.48%,-0.13),and the values in the parentheses are demonstrated the same as above.Both the CRM and Er are shown to be very low values,which points to the accuracy and reliability of the model investigated.The accuracy of model is high and reliable.The results indicated that thermal infrared image can be used potentially for inversion of winter wheat yield and biomass.DU Wen-yong ZHANG Lu-da HU Zhen-fang Shamaila Z ZENG Ai-jun SONG Jian-li LIU Ya-jia Wolfram S Joachim M HE Xiong-kui 2011光谱学与光谱分析2011,31,6:3
