| 2 | Cold acclimation improves photosynthesis by regulating the ascorbate–glutathione cycle in chloroplasts of Kandelia obovata显示文摘As the most northerly mangrove species in China, Kandelia obovata may undergo extreme cold event stress. Enhancing the cold tolerance of this species is crucial to its successful afforestation. This study aimed to determine the resistance of K. obovata seedlings to low temperature stress by cold acclimation and to explain the mechanisms for alleviating cold injury. To understand these mechanisms, seedlings that were acclimatized and not acclimatized were exposed to 5℃/- 2℃(day/night)for 48 h.Results showed that low temperature stress reduced leaf photosynthesis of non-acclimatized seedlings by inducing oxidative stress and structural damage to chloroplasts. These phenomena were shown by increasing levels of malondialdehyde (MDA), O2-and H2O2, as well as decreasing enzyme activities in the ascorbate–glutathione (AsA-GSH) cycle. However, cold-acclimatized seedlings had improved photosynthetic rates and efficiency of photosystem II (PSII) under low temperature stress. Compared with non-acclimatized seedlings, leaves of coldacclimatized seedlings under low temperature stress for 48 h exhibited higher anti-oxidative enzyme activities, lower levels of O2^- and H2O2, less damage to chloroplast structure, and removed 33.7% of MDA at low temperature stress for 48 h. The data indicate that cold acclimation enhances photosynthetic capacity by effectively regulating activation in the PSII electron transport and the AsA–GSH cycle to scavenge excess ROS in chloroplasts, while the latter is more important. | Weicheng Liu Chunfang Zheng Jinong Chen Jianbiao Qiu Zhixing Huang Qi Wang Yong Ye | 2019 | Journal of Forestry Research2019,30,3: | 11 |
| 3 | Effect of VC addition on the microstructure and properties of Ti(C,N)-based nano cermets显示文摘In this paper,Ti(C,N)-based nano cermets were prepared by nano particles,and the effect of VC addition on the microstructure and proper-ties of Ti(C,N)-based nano cermets was investigated.The results showed that there existed black-core grayish-rim structure as well as gray-core grayish-rim structure in VC-doped Ti(C,N)-based nano cermets.With the increase of VC addition,the number of gray cores in-creased,the lattice parameter of Ti(C,N) phase increased,the grain size decreased,the hardness and fracture toughness of Ti(C,N)-based nano cermets were enhanced,and nearly full densification could be achieved.However,excessive addition of VC to 1 wt% resulted in slight decrease in hardness and fracture toughness.Some deep dimples were found in the fracture surface of cermets with VC addition,which cor-responded to ductile fracture. | YING Xiayu XIONG Ji GUO Zhixing CHEN Jianzhong XIONG Sujian YANG Mei FAN Hongyuan | 2011 | Rare Metals2011,30,6: | 7 |
| 4 | Synthesis and electrochemical properties of Al-doped LiVPO_4F cathode materials for lithium-ion batteries显示文摘Al-doped LiVPO4F cathode materials LiAlxV1-xPO4F were prepared by two-step reactions based on a car-bothermal reduction (CTR) process. The properties of the Al-doped LiVPO4F were investigated by X-ray diffraction (XRD),scanning electron microscopy (SEM),and electrochemical measurements. XRD studies show that the Al-doped LiVPO4F has the same triclinic structure (space group p1 ) as the undoped LiVPO4F. The SEM images exhibit that the particle size of Al-doped LiVPO4F is smaller than that of the undoped LiVPO4F and that the smallest particle size is only about 1 μm. The Al-doped LiVPO4F was evaluated as a cathode material for secondary lithium batteries,and exhibited an improved reversi-bility and cycleability,which may be attributed to the addition of Al3+ ion by stabilizing the triclinic structure. | ZHONG Shengkui YIN Zhoulan WANG Zhixing CHEN Qiyuan | 2007 | Rare Metals2007,26,5: | 6 |
| 5 | Development of highly glyphosate-tolerant tobacco by coexpression of glyphosate acetyltransferase gat and EPSPS G2-aroA genes显示文摘The widely used herbicide glyphosate targets 5-enolpyruvylshikimate-3-phosphate synthase(EPSPS).Glyphosate acetyltransferase(GAT)effectively detoxifies glyphosate by N-acetylation.With the aim of identifying a new strategy for development of glyphosate-tolerant crops,the plant expression vector pG2-GAT harboring gat and G2-aroA(encoding EPSPS)has been transformed into tobacco(Nicotiana tabacum)to develop novel plants with higher tolerance to glyphosate.Results from Southern and Western blotting analyses indicated that the target genes were integrated into tobacco chromosomes and expressed effectively at the protein level.Glyphosate tolerance was compared among transgenic tobacco plants containing gat,G2-aroA,or both genes.Plants containing both gat and G2-aroA genes were the most glyphosate-tolerant.This study has shown that a combination of different strategies may result in higher tolerance in transgenic crops,providing a new approach for development of glyphosate-tolerant crops. | Baoqing Dun Xujing Wang Wei Lu Ming Chen Wei Zhang Shuzhen Ping Zhixing Wang Baoming Zhang Min Lin | 2014 | The Crop Journal2014,2,Z1: | 4 |
| 6 | Transarterial infusion chemotherapy with FOLFOX for advanced hepatocellular carcinoma:a multi-center propensity score matched analysis of real-world practice显示文摘Background:To compare the treatment effectiveness and safety among transarterial infusion chemotherapy(TAI)with FOLFOX regimen,transarterial chemoembolization(TACE),and sorafenib in patients with BCLC stage C hepatocellular carcinoma(HCC).Methods:The data of consecutive patients with BCLC stage C HCC treated with TAI,TACE,or sorafenib from January 2015 to December 2018 at three centers were retrospectively analyzed.Propensity-score matched(PSM)analysis was pairwise performed to reduce selection bias.Treatment effectiveness and safety were evaluated and compared using the Kaplan-Meier method,log-rank test,Cox regression models,andχ2 test.Results:The median overall survival(OS)in the matched TAI cohort was significantly longer than the sorafenib cohort(19.6 vs.7.5 months,P=0.009),and the TACE cohort(estimated 27.8 vs.6.6 months,P<0.001).The difference in median progression-free survival(PFS)between the matched TAI and sorafenib cohorts was not significant(5.8 vs.2.3 months,P=0.219).The median PFS in the matched TAI cohort was significantly longer than the TACE cohort(6.5 vs.2.8 months,P<0.001).The objective response rate(ORR)in the matched TAI cohort was significantly higher than the sorafenib cohort(36.4%vs.0.0%,P<0.001)and the TACE cohort(48.7%vs.4.7%,P<0.001).The incidences of adverse events(AEs)were similar among these three cohorts.Conclusions:TAI with FOLFOX regimen was an effective and safe therapy that improved survival of patients with BCLC stage C HCC. | Shaohua Li Jie Mei Qiaoxuan Wang Feng Shi Hongyan Liu Ming Zhao Lianghe Lu Yihong Ling Zhixing Guo Yabing Guo Xiaoming Chen Ming Shi Wan Yee Lau Wei Wei Rongping Guo | 2021 | Hepatobiliary Surgery and Nutrition2021,10,5: | 2 |

| 19 | Study on Soil Infiltration Capability and Its Impact Factors of Different Land-use Types in Purple Soil Region显示文摘Soil infiltration capability is the hot spot topic of soil erosion studies and soil physical and chemical properties have great influence on it. A new infiltration method point- source infiltration method was used to precisely evaluate the infiltration capability in different purple soil land- use types. And correlation analysis on soil physical and chemical properties and soil infiltration capability of different land- use types was performed. Results showed that:( i) there is a large difference among soil physical and chemical properties in different land- use types,soil water content,non- capillary porosity,capillary porosity,content of > 0. 25 mm aggregates and organic matter content in the top soil are greater than those in the subsoil;( ii) soil infiltration capability showed differences among different land- use types. Land use showed great effects,in general,the order of decrease on initial infiltration rate and average infiltration rate was: woodland slope > slope farmland >grassland,the order of decrease on steady infiltration rate was: slope farmland > woodland > grassland and the time reaching stable state was:slope farmland > woodland > grassland;( iii) correlation analysis showed that there was a significantly positive correlation between initial infiltration rate and wet sieve MWD value and structural damage rate,and it had a significantly negative correlation with capillary porosity;( iv)steady infiltration rate and non- capillary porosity showed the significantly positive correlation,and it had a significantly negative correlation with the soil bulk density;( v) the average infiltration rate and non- capillary porosity and structural damage rate showed a positive correlation and the correlation coefficient was large and there was a negative correlation between average infiltration rate and soil bulk density and capillary porosity,and the absolute value of correlation coefficient was relatively large. The results of this study can provide the theoretical basis for soil infiltration study in purple soil area. | Bin MO Xiaoyan CHEN Tao LIU Yicui YANG Zhixing LIN Xiufeng HUANG Qiliang HUANG Hui JIAN Tujin ZHOU Yunkang SHEN | 2016 | Asian Agricultural Research2016,8,3: | 0 |
| 20 | Computer vision-aided DEM study on the compaction characteristics of graded subgrade filler considering realistic coarse particle shapes显示文摘The compaction quality of subgrade filler strongly affects subgrade settlement.The main objective of this research is to analyze the macro-and micro-mechanical compaction characteristics of subgrade filler based on the real shape of coarse particles.First,an improved Viola-Jones algorithm is employed to establish a digitalized 2D particle database for coarse particle shape evaluation and discrete modeling purposes of subgrade filler.Shape indexes of 2D subgrade filler are then computed and statistically analyzed.Finally,numerical simulations are performed to quantitatively investigate the effects of the aspect ratio(AR)and interparticle friction coefficient(μ)on the macro-and micro-mechanical compaction charac-teristics of subgrade filler based on the discrete element method(DEM).The results show that with the increasing AR,the coarse particles are narrower,leading to the increasing movement of fine particles during compaction,which indicates that it is difficult for slender coarse particles to inhibit the migration of fine particles.Moreover,the average displacement of particles is strongly influenced by the AR,indicating that their occlusion under power relies on particle shapes.The dis-placement and velocity of fine particles are much greater than those of the coarse particles,which shows that compaction is primarily a migration of fine particles.Under the cyclic load,the interparticle friction coefficientμhas little effect on the internal structure of the sample;under the quasi-static loads,however,the increase inμwill lead to a significant increase in the porosity of the sample.This study could not only provide a novel approach to investigate the compaction mechanism but also establish a new theoretical basis for the evaluation of intelligent subgrade compaction. | Taifeng Li Kang Xie Xiaobin Chen Zhixing Deng Qian Su | 2024 | Railway Engineering Science2024,32,2: | 0 |
