| 1 | Stable classi?cation with limited sample: transferring a 30-m resolution sample set collected in 2015 to mapping 10-m resolution global land cover in 2017显示文摘As the world strives to reduce the impact of population growth, urbanization, agricultural expansion, and climate change on food security, energy and water shortage, resource over-exploration, biodiversity loss, environmental pollution, and ultimately human health, timely and higher resolution land cover information is urgently needed to achieve the sustainable development goals of the United Nations. | Peng Gong Han Liu Meinan Zhang Congcong Li Jie Wang Huabing Huang Nicholas Clinton Luyan Ji Wenyu Li Yuqi Bai Bin Chen Bing Xu Zhiliang Zhu Cui Yuan Hoi Ping Suen Jing Guo Nan Xu Weijia Li Yuanyuan Zhao Jun Yang Chaoqing Yu Xi Wang Haohuan Fu Le Yu Iryna Dronova Fengming Hui Xiao Cheng Xueli Shi Fengjin Xiao Qiufeng Liu Lianchun Song | 2019 | Science Bulletin2019，64，6： | 166 |
| 2 | Dissecting and Enhancing the Contributions of High-Molecular-Weight Glutenin Subunits to Dough Functionality and Bread Quality显示文摘Dear Editor, Seed storage proteins (SSPs) are frequently important determinants of crop quality traits (Shewry and Casey,1999).Dissecting and enhancing the genetic contributions of individual SSPs to their target traits are essential for effectively improving crop quality attributes.However,such a task is often difficult to accomplish,because SSPs are frequently expressed from multigene families and exhibit strong allelic variation.Consequently,detailed knowledge of the function of individual SSPs in crop quality trait is still limited.This scenario is well illustrated by high-molecular-weight glutenin subunits (HMWGSs),a complex family of SSPs that are involved in wheat enduse quality through affecting dough functionality (Békés,2012;Rasheed et al.,2014). | Yiwen Li Xuefi An Ran Yang Xiaomin Guo Guidong Yue Renchun Fan Bin Li Zhensheng Li Kunpu Zhang Zhenying Dong Luyan Zhang Jiankang Wang Xu Jia Hong-Qing Ling Aimin Zhang Xiangqi Zhang Daowen Wang | 2015 | Molecular Plant2015，8，2： | 9 |
| 3 | Protective effects of curcumin against human immunodeficiency virus 1 gp120 V3 loop-induced neuronal injury in rats显示文摘Curcumin improves the learning and memory deficits in rats induced by the gp120 V3 loop. The present study cultured rat hippocampal neurons with 1 nM gp120 V3 loop and 1 μM curcumin for 24 hours. The results showed that curcumin inhibited the gp120 V3 loop-induced mitochondrial membrane potential decrease, reduced the mRNA expression of the pro-apoptotic gene caspase-3, and attenuated hippocampal neuronal injury. | Zheng Gong Lijuan Yang Hongmei Tang Rui Pan Sai Xie Luyan Guo Junbin Wang Qinyin Deng Guoyin Xiong Yanyan Xing Jun Dong | 2012 | Neural Regeneration Research2012，7，3： | 5 |
| 4 | Protective effect of curcumin on tumor necrosis factor-alpha-induced neuronal damage in the rat hippocampus A relationship to the inhibition of neuronal Ca^(2+) influx显示文摘BACKGROUND: Previous studies of curcumin have focused mainly on its cytotoxic properties for antitumor therapy.There are few studies addressing the application of curcumin in the prevention and treatment of nervous system diseases.OBJECTIVE: To observe the protective effect of curcumin against tumor necrosis factor-alpha (TNF-α)-induced neuronal damage in the rat hippocampus and to explore the intervention effect of curcumin on Ca2+ influx following neuronal damage.DESIGN,TIME AND SETTING: A cell morphological and physiological study was performed at the Institute of Brain Research,Medical College of Jinan University,China,from December 2006 to June 2007.MATERIALS: Curcumin (Sigma,USA) and TNF-α (Sigma,USA) were used in this study.METHODS: Hippocampal neurons were isolated from one-day neonatal rats and primarily cultured for 5 days.Following this they received 1 μmol/L curcumin and 100 ng/mL TNF-α pre-treatment.Dynamic morphological changes were observed for 1 hour by inverted microscopy.At 48 hours post-treatment,static morphological characteristics of the neurons were observed using inverted microscopy.Subsequently,hippocampal neurons were primarily cultured for 7 days,after receiving 1 μmol/L curcumin and 4.5 ng/mL TNF-α pre-treatment.Intracellular free Ca2+ was measured using Fluo 3/acetoxymethyl ester.MAIN OUTCOME MEASURES: Effects of curcumin on TNF-α-induced neuronal damage and Ca2+ influx in the rat hippocampus were measured.RESULTS: Following curcumin treatment,TNF-α-induced neurons grew as normal.TNF-α induced a rapid Ca2+ influx into the neuronal cytoplasm;however,Ca2+ fluorescence intensity only slightly increased when neurons were co-perfused with curcumin and TNF-α.CONCLUSION: Curcumin has a protective effect on rat hippocampal neurons possibly by reducing the TNF-α-induced rapid Ca2+ influx into neuronal cytoplasm and by maintaining the Ca2+ homeostasis. | Luyan Guo Rongbo Tu Min Lin Jun Dong | 2010 | Neural Regeneration Research2010，5，2： | 2 |
| 5 | Effect of the withdrawal rate on the microstructure and thermal durability of a third-generation single crystal superalloy显示文摘Single crystal Ni-based superalloys are the typical structural materials for high-pressure turbine blades,and their microstructure is critical in determining their mechanical properties.The withdrawal rate is a key parameter affecting the microstructure during the single crystal growth process.In the present work the effect of the withdrawal rate on the microstructure of a third-generation single crystal superalloy containing 6.8 wt%Re has been investigated,and the creep resistance of the alloy determined.The results showed that increased withdrawal rate refined the dendritic structure,reduced dendritic arm spacing,promoted the growth of secondary tertiary dendrites and decreased solidification segregation with a reduced size ofγ’phase.The porosity density of the ascast alloy first decreased and then increased with the withdrawal rate,while the minimum porosity densityoccurred when the alloy was under the solidification condition of withdrawal rate of 4.5 mm/min.The maximum creep rupture life of 326.4 h of the heat-treated alloys under the test condition of 1100℃/140 MPa also appeared at the alloys under the withdrawal rates of 4.5 mm/min.It is believed that the minimum porosity density and reduced size of theγ’phase may be the main reasons for the enhanced creep rupture life of the alloys with withdrawal rates of 4.5 mm/min.This investigation provides theoretical support and a practical basis for the development of third-generation single crystal superalloys. | Yunsong Zhao Mai Zhang Luyan Yang Yuanyuan Guo Jian Zhang Hui Lu Yanhui Chen Dingzhong Tang | 2021 | Progress in Natural Science:Materials International2021，31，3： | 0 |
| 6 | Stimulated Brillouin interaction between guided phonons and photons in a lithium niobate waveguide显示文摘The Brillouin scattering is one of the strongest nonlinear optical effects in dielectrics[1].In particular,the backward Brillouin scattering(BBS)provides an efficient method to achieve low-noise optical gain for active photonics[2]and the coherent interconnects between 10 GHz phonons and photons[3].However,previous studies on BBS are primarily limited to the unconfined phonons[1]or phonon confined in suspended structures[4-6]. | Yuan-Hao Yang Jia-Qi Wang Zheng-Xu Zhu Xin-Biao Xu Qiang Zhang Juanjuan Lu Yu Zeng Chun-Hua Dong Luyan Sun Guang-Can Guo Chang-Ling Zou | 2024 | Science China(Physics,Mechanics & Astronomy)2024，67，1： | 0 |
