1Ammonia volatilization from a Chinese cabbage field under different nitrogen treatments in the Taihu Lake Basin, China显示文摘Ammonia(NH_3) volatilization is a major pathway of nitrogen(N) loss from soil-crop systems.As vegetable cultivation is one of the most important agricultural land uses worldwide,a deeper understanding of NH_3 volatilization is necessary in vegetable production systems.We therefore conducted a 3-year(2010–2012) field experiment to characterize NH_3 volatilization and evaluate the effect of different N fertilizer treatments on this process during the growth period of Chinese cabbage.Ammonia volatilization rate,rainfall,soil water content,p H,and soil NH_4^+were measured during the growth period.The results showed that NH_3 volatilization was significantly and positively correlated to topsoil p H and NH4+concentration.Climate factors and fertilization method also significantly affected NH_3 volatilization.Specifically,organic fertilizer(OF) increased NH_3 volatilization by 11.77%–18.46%,compared to conventional fertilizer(CF,urea),while organic–inorganic compound fertilizer(OIF) reduced NH_3 volatilization by 8.82%–12.67% compared to CF.Furthermore,slow-release fertilizers had significantly positive effects on controlling NH_3 volatilization,with a 60.73%–68.80% reduction for sulfur-coated urea(SCU),a 71.85%–78.97% reduction for biological Carbon Power~® urea(BCU),and a 77.66%–83.12% reduction for bulk-blend controlled-release fertilizer(BBCRF)relative to CF.This study provides much needed baseline information,which will help in fertilizer choice and management practices to reduce NH_3 volatilization and encourage the development of new strategies for vegetable planting.Linan Shan Yunfeng He Jie Chen Qian Huang Hongcai Wang 2015Journal of Environmental Sciences2015,27,12:28
2ALOX15-launched PUFA-phospholipids peroxidation increases the susceptibility of ferroptosis in ischemia-induced myocardial damage显示文摘Myocardial ischemia/reperfusion(/R)injury is a classic type of cardiovascular disease characterized by injury to cardiomyocytes leading to various forms of cell death.It is believed that irreversible myocardial damage resulted from I/R occurs due to oxidative stress evoked during the reperfusion phase.Here we demonstrate that ischemia triggers a specific redox reaction of polyunsaturated fatty acids(PUFA)-phospholipids in myocardial cells,which acts as a priming signaling that initiates the outbreak of robust oxidative damage in the reperfusion phase.Using animal and in vitro models,the crucial lipid species in I/R injury were identifed to be oxidized PUFAs enriched phosphatidylethanolamines.Using multi-omics,arachidonic acid 15-lipoxygenase-1(ALOx15)was identified as the primary mediator of ischemia-provoked phospholipid peroxidation,which was further confirmed using chemogenetic approaches.Collectively,our results reveal that ALOx15 induction in the ischemia phase acts as a'burning point'to ignite phospholipid oxidization into ferroptotic signals.This finding characterizes a novel molecular mechanism for myocardial ischemia injury and offers a potential therapeutic target for early intervention of V/R injury.Xiao-Hui Ma Jiang-Han-Zi Liu Chun-Yu Liu Wan-Yang Sun Wen-Jun Duan Guan Wang Hiroshi Kuriara Rong-Rong He Yi-Fang Li Yang Chen Hongcai Shang 2022Signal Transduction and Targeted Therapy2022,7,9:2

7Influence of Magnetic Field Intensity on the Shape of the μ-T Curves for Fe73.5Cu1Nb3Si13.5B9 Alloy显示文摘Under different magnetic field intensities, the dependence of the permeability μ on temperature T(μ-T curve) for the Fe7.3Cu1Nb3Si13.5B9 alloy annealed at 350-620℃ was investigated. The results showed that the magnetic field intensity had a remarkable influence on the shape of μ-T curves. For amorphous alloy, the sharp Hopkinson peak of μ-T curve disappeared gradually with the increase of magnetic field intensity.Yajing ZHANG, Kaiyuan HE, Zhi WANG, Changsheng LIU, Lizhi CHENG and Hongcai YANGSchool of Materials & Metallurgy, Northeastern University, Shenyang 110004, China 2002Journal of Materials Science & Technology2002,18,3:0
8Microstructure tailoring in nanostructured thermoelectric materials显示文摘Progresses in thermoelectric(TE)materials will contribute to solving the world's demands for energy and global climate protection.It also calls for higher ZT to achieve ideal commercial conversion efficiency.As an effective way,nanostructuring can reduce the thermal conductivity by the selective scattering of phonons or enhance Seebeck coefficient via modification of the density of the states,resulting in good ZT value.Meanwhile,TE properties of nanostructured materials should depend on the size and morphology of the microstructure features.This review emphasizes the developments in the TE bulk materials at the nanoscale in the past several years and summarizes the understanding in this active field.Qinghui Jiang Junyou Yang Yong Liu Hongcai He 2016Journal of Advanced Dielectrics2016,6,1:0
9Wenxin granule for cardiac arrhythmia: an overview of systematic reviews显示文摘目的:对稳心颗粒治疗心律失常的系统评价/meta分析进行再评价,为临床应用提供证据;分析目前研究中存在的问题,为研究者提供可能的优先研究主题。方法:从8 个数据库中检索稳心颗粒治疗心律失常的系统评价。分别用AMSTAR和GRADE评估系统评价的方法学质量和证据质量。结果:共纳入1 9 项系统评价,涉及52, 9 0 5 个参与者。AMSTAR评分3-10分,平均6 .5 分,中位数为6 分, 9 (9/19, 47.37°%)项系统评价的AMSTAR得分大于7 分,对其中的6 项研究采用GRADE评估其证据质量。结果显示,所有研究的证据质量都在极低和低之间,无中、高质量证存在。从结局指标报告来看,没有系统评价评估终点指标,虽然有部分研究报告了不良反应/事件,但很少有研究进行因果关系判断。系统评价结局指标矩阵显示,结局指标报告存在明显的异质性及不完全报告的情况,导致有些研究不能进行m eta分析。同时,一些原始研究由于结局指标报告不合理而被不能纳入系统评价(如未报告相关结局指标,治疗时间不合适/不清楚,数据不完全或无法提取)。结论:稳心颗粒治疗心律失常的疗效和安全性证据有限,未来需要更多的高质量R C T s和系统评价提供证据。在未来的研究中,有必要构建心律失常核心指标集,以提高结局指标报告水平,减少由于结局指标报告不合理而造成的浪费。Ruijin Qiu Changming Zhong Huichan Yuan Xiaoyi Tang Ya Huang Tianmai He Songjie Han Manke Guan Min Li Jiayuan Hu Xiaoyu Zhang Jing Chen Hongcai Shang 2019TMR Modern Herbal Medicine2019,2,2:0
10Artificial intelligence-based medical image segmentation for 3D printing and naked eye 3D visualization显示文摘Image segmentation for 3D printing and 3D visualization has become an essential component in many fields of medical research,teaching,and clinical practice.Medical image segmentation requires sophisticated computerized quantifications and visualization tools.Recently,with the development of artificial intelligence(AI)technology,tumors or organs can be quickly and accurately detected and automatically contoured from medical images.This paper introduces a platform-independent,multi-modality image registration,segmentation,and 3D visualization program,named artificial intelligence-based medical image segmentation for 3D printing and naked eye 3D visualization(AIMIS3D).YOLOV3 algorithm was used to recognize prostate organ from T2-weighted MRI images with proper training.Prostate cancer and bladder cancer were segmented based on U-net from MRI images.CT images of osteosarcoma were loaded into the platform for the segmentation of lumbar spine,osteosarcoma,vessels,and local nerves for 3D printing.Breast displacement during each radiation therapy was quantitatively evaluated by automatically identifying the position of the 3D printed plastic breast bra.Brain vessel from multimodality MRI images was segmented by using model-based transfer learning for 3D printing and naked eye 3D visualization in AIMIS3D platform.Guang Jia Xunan Huang Sen Tao Xianghuai Zhang Yue Zhao Hongcai Wang Jie He Jiaxue Hao Bo Liu Jiejing Zhou Tanping Li Xiaoling Zhang Jinglong Gao 2022Intelligent Medicine2022,2,1:0
11Novel fast ionic conductor ceramic composite separator for highperformance safe Li-ion power batteries显示文摘The ceramic composite separators coated with silica or alumina particles have been used in power batteries due to their better electrolyte wettability and better thermal stability compared with bare polymer separators.However,these oxide ceramics are Liþion insulators,which increase internal resistance and hinder the improvement of rate capability of batteries.Herein,we report a strategy to further improving the performance of lithium-ion batteries(LIBs)by using fast ionic conductor ceramic composite separator as an alternative to traditional ceramic coated separators.Lithium lanthanum titanate(LLTO),a fast ionic conductor with excellent room temperature bulk conductivity,are coated on the common polyethylene(PE)separators.Our results demonstrate that such a novel LLTO-coated separator possess excellent electrolyte wettability and thermal stability;and the assembled NCM523/graphite lithium-ion pouch cells with LLTO-coated separator show better rate capability and cyclic performance with 88.7%capacity retention after 1000 cycles at room temperature compared with the pouch cells with Al2O_(3)-coated separators.The fast ionic conductor ceramic composite separators will be a potential competitor to the next-generation novel separators for high-performance Li-ion power batteries.Yuchuan Feng Minghui Wang Lina Gao Zhaoling He Kai Chen Zheng Li Hongcai He Yuanhua Lin 2022Journal of Materiomics2022,8,6:0
