| 1 | A Method for Detection of Main Metabolites in Aromatic Rice Seeds显示文摘[Objective] A method was developed for the analysis of main metabolites in aromatic rice seeds by gas chromatography-mass spectrometry( GC-MS).[Method]The main metabolites in seeds of 9 different aromatic rice varieties were compared and analyzed with two methods. Method 1: the compound was extracted by the mixture of anhydrous ethanol and methylene chloride( V/V = 1∶ 1) at 60 ℃ for 3 h in water bath; the extract was isolated and detected by gas chromatography-mass spectrometry using HP-5 capillary column with scan monitoring mode. Method 2: the main metabolites in aromatic rice seeds were detected using headspace solid phase micro-extraction and gas chromatography mass spectrometry( GC-MS). [Result]Fifteen types of common metabolites were found in 9 different aromatic rice varieties. Method 1 was more effective than method 2 in detecting the main metabolites in aromatic rice seeds. [Conclusion]This study provides an important reference for clarifying the metabolic pathway of main metabolites in aromatic rice and lays the foundation for further rice breeding. | Bo PENG Dongyan KONG Xiaohua SONG Huilong LI Lulu HE Andong GONG Yanfang SUN Ruihua PANG Lin LIU Jintao LI Qiying ZHOU Yaqin HUANG Bin DUAN Shizhi SONG Hongyu YUAN | 2018 | Agricultural Biotechnology2018，7，1： | 6 |
| 2 | Chalkiness Characters and Scanning Electron Microscope Observation of Rice Grain Endosperm of Japonica Varieties in Southern Henan显示文摘Chalkiness characters affect not only the grain appearance,milling,eating and cooking qualities but also the grain nutritional quality in rice,thus it is one of the most important traits in rice. It is very important for us to investigate the relation of the chalkiness formation and the development of endosperm structure and starch granule of different rice varieties. Here,we have investigated the chalkiness characters such as chalkiness rate,chalkiness degree and chalkiness area in 15 japonica rice varieties from southern Henan. Furthermore,the endosperm structure and starch granules of rice grain were also observed with scanning electron microscope. The results showed that the 15 japonica varieties have a significantly linear relationship between the chalkiness rate and chalkiness degree. Among the varieties,the biggest difference is the chalkiness rate,the second is the chalkiness area,and the last is the chalkiness degree. Moreover,there is a certain correlation between the distribution of starch granules,the arrangement of endosperm cells and the occurrence of grain chalkiness in the different rice varieties. For the same variety,the starch granules of chalky and non-chalky grains have obvious difference,while the starch granules from the transparent part of chalky rice and non-chalky rice do not have significant difference. The results would provide useful references for the improvement of grain quality in rice. | Bo PENG Yanfang SUN Dongyan KONG Ruihua PANG Xiaohua SONG Huilong LI Jintao LI Qiying ZHOU Qiu HAN Shizhi SONG Hongyu YUAN | 2017 | Asian Agricultural Research2017，9，3： | 5 |

| 5 | Understanding the role of alloyed Ni and Cu on improving corrosion resistance of low alloy steel in the simulated Beishan groundwater显示文摘The corrosion behavior of NiCu low alloy steel and Q235 low carbon steel as the candidate materials for geological disposal containers of high-level radioactive waste in the simulated Beishan groundwater was comparatively studied by weight loss test,electrochemical measurements,scanning electron microscope(SEM),electron probe microanalysis(EPMA),X-ray diffraction(XRD),Raman spectrum and X-ray photoelectron spectroscopy(XPS).The electrochemical results showed that the corrosion potential of NiCu steel and Q235 steel gradually increased with the immersion time.Simultaneously,the cathodic process transited from hydrogen evolution reaction(HER) control to the rust reduction control,while the anodic process was always dominated by the active dissolution of iron.By comparison,both the cathodic resistance and the anodic dissolution resistance of NiCu steel corrosion were apparently higher than that of Q235 steel.The results of rust layer characterization indicated that Ni and Cu elements could be enriched in the inner rust layer of NiCu steel and the rust layer was more compact.As the main corrosion products,the content of α-FeOOH in the rust layer of NiCu steel was obviously increased more than that of Q235 steel.Fe_(6)(OH)_(12)SO_(4)stably existed in the corrosion products of NiCu steel because Ni(Ⅱ) or Cu(Ⅱ)could substitute Fe(Ⅱ) of Fe_(6)(OH)_(12)SO_(4)and increased its oxidation resistance,Moreover,Ni and Cu could also make Fe3O4ionic selective by doping.After the long-term immersion,the corrosion mass loss of NiCu steel was significantly lower than Q235 steel,which further confirmed the benefits of Ni and Cu alloying on improving the steel corrosion resistance. | Yupeng Sun Xin Wei Junhua Dong Nan Chen Hanyu Zhao Qiying Ren Wei Ke | 2022 | Journal of Materials Science & Technology2022，，35： | 1 |
| 6 | Genetic Analysis and Improvement Strategies of Protein Content in Rice Seeds显示文摘Enhancing the nutritional quality of food crops is a way to improve human nutrition and health.Grain protein content(GPC)is an important nutritional quality trait for rice and many other crops.Therefore,it will be very significant to increase GPC and improve rice quality.This paper mainly reviewed the genetic studies GPC in rice,mapping and cloning of QTLs and genes associated with GPC.However,little is known about the molecular mechanism and gene function related to GPC in rice.Thus,here we put forward the genetic strategy by gene pyramiding or molecular marker assisted selection to improve GPC and nutritional quality in rice.This review could provide important information for genetic improvement of grain nutritional quality of rice. | Bo PENG Yanfang SUN Dongyan KONG Ruihua PANG Xiaohua SONG Huilong LI Lin LIU Xian-wen LI Jintao LI Qiying ZHOU Bin DUAN Huihui LIU Yuhan ZUO Yanlin HAO Shizhi SONG Hongyu YUAN | 2017 | Agricultural Biotechnology2017，6，4： | 1 |
| 7 | Multifunctional Gd-CuS loaded UCST polymeric micelles for MR/PA imaging-guided chemo-photothermal tumor treatment显示文摘Hepatocellular carcinoma(HCC)is a life-threatening disease for which there is no effective treatment currently.Novel theranostics simultaneously having excellent imaging and therapeutic functions are highly desired in cancer therapy.Herein,we develop the sialic acid(SA)modified polymeric micelles at an upper critical solution temperature(UCST)of 43℃(sialic acid-poly(ethylene glycol)-poly(acrylamide-co-acrylonitrile),SA-PEG-p(AAm-co-AN)),which further encapsulated with doxorubicin(DOX)and Gd-CuS nanoparticles(Gd-CuS NPs)for chemo-photothermal treatment of HCC guided by magnetic resonance(MR)/photoacoustic(PA)dual-mode imaging.The resultant SA-PEG-p(AAm-co-AN)/DOX/Gd-CuS(SPDG)had an excellent photothermal conversion efficiency,enabling SPDG with an instantaneous release behavior of DOX under near-infrared(NIR)irradiation.This study also revealed that SPDG could actively target to HCC,which was due to that SA had a high affinity with E-selectin overexpressed at the tumor site.Moreover,benefiting from the HCC-targeted ability and NIR light-controlled on-demand delivery of DOX,SPDG showed a superior potential in MR/PA dual-mode imaging-guided chemo-photothermal treatment.Overall,our study reveals that the designed SPDG may be used as an ideal multifunctional nanoplatform for cancer theranostics. | Yan Du Di Liu Mingchen Sun Gaofeng Shu Jing Qi Yuchan You Yiting Xu Kai Fan Xiaoling Xu Feiyang Jin Jun Wang Qiying Shen Luwen Zhu Xiaoying Ying Jiansong Ji Liming Wu Daren Liu Yongzhong Du | 2022 | Nano Research2022，15，3： | 0 |

| 9 | Influence of Deteriorated Bentonite Sediments on the Corrosion Behavior of NiCu Low Alloy Steel显示文摘The corrosion evolution of steel disposal container largely depends on the evolution of surrounding bentonite environment in the long-term geological disposal of high-level radioactive wastes. This study focused on the influence of the deteriorated bentonite sediments on the corrosion behavior of NiCu low alloy steel in the top supernatant and bottom slurry formed by Gaomiaozi bentonite and 0.05 M NaHCO_(3) + 0.1 M NaCl + 0.1 M Na_(2)SO_(4) solution. In the top supernatant, the cathodic process of the steel corrosion was transformed from the reduction in oxygen to the reduction in ferric corrosion products with time as same as that in the blank solution. While in the bottom bentonite slurry, the cathodic process always maintained as the hydrogen evolution reaction due to the coverage of more bentonite sediments. Meanwhile, the corrosion rate of NiCu steel was obviously decreased. In addition, the localized corrosion tendency of the steel could also be reduced by the large amount of deteriorated bentonite sediments. | Xin Wei Junhua Dong Yupeng Sun Nan Chen Qiying Ren Madhusudan Dhakal Xiaofang Li Wei Ke | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，6： | 0 |
| 10 | Expression and Regulation of Plant Amino Acid Transporters and Their Application in Crop Genetic Improvement显示文摘Amino acid transporters( AATs) play an important role in transport process of various amino acids,which are indispensable in plant growth and development,while many putative AATs have been identified and the complete genomic sequences of the important plants have already been completed by splicing and assembling. There is still little knowledge about the expression,regulation and various biological functions of AATs in plants,including the major food crops. This study mainly reviewed the expression,regulation and various biological functions of AATs in plants,and the application of AATs in crop genetic improvement was also prospected. Thus,this review will provide important information for genetic improvement of staple food crops in plants. | Bo PENG Dongyan KONG Lulu HE Yu PENG Juan PENG Qingqing XIN Xiaohua SONG Yuchen LIU Yanfang SUN Ruihua PANG Huilong LI Guiying GUO Jintiao LI Quanxiu WANG Qiying ZHOU Shizhi SONG Bin DUAN Hongyu YUAN | 2019 | Agricultural Biotechnology2019，8，1： | 0 |
| 11 | Rare TBK1 variants in patients with frontotemporal dementia and amyotrophic lateral sclerosis in a Chinese cohort显示文摘Background:The TANK-Binding Kinase 1(TBK1)gene has recently been identified as the third or fourth most frequent cause of frontotemporal dementia(FTD)and amyotrophic lateral sclerosis(ALS).The aim of this study was to assess the genetic contribution of TBK1 in a Chinese cohort.Methods:A total of 270 cases with ALS,FTD,or their combination were recruited into this study.All the coding exons of TBK1 and intron-exon boundaries were sequenced using Sanger sequencing.The frequency of TBK1 variants and the correlation with clinical phenotypes were analyzed.Results:A novel mutation(c.1959_1960insGT,p.E653fs)was identified in a sporadic case with semantic dementia,secondarily developing ALS.Another novel variant(c.2063_2064delTT,p.L688Rfs*14)was found in an ALS-FTD family.Totally,the TBK1 variants could only account for 0.7% of cases.Conclusions:This study enlarges the genetic and phenotypic spectrum of TBK1 mutation in a Chinese cohort.Our data indicates that TBK1 mutation is not a common cause for ALS and FTD in Chinese patients. | Bin Jiao Qiying Sun Zhenhua Yuan Junling Wang Lin Zhou Xinxiang Yan Beisha Tang Lu Shen | 2018 | Translational Neurodegeneration2018，7，1： | 0 |
| 12 | Effects of Aerobic and Anoxic Conditions on the Corrosion Behavior of NiCu Low Alloy Steel in the Simulated Groundwater Solutions显示文摘The present work focused on investigating the corrosion behavior of NiCu low alloy steel in 0.05 M NaHCO_(3) solutions with different Cl−concentrations under the aerobic–anoxic condition.The results showed that NiCu steel tended to be pseudo-passivated in the solutions of 0.05 M NaHCO_(3) and 0.05 M NaHCO_(3)+0.01 M NaCl exposed to air.The cathodic process transformed from oxygen reduction to the common reduction of oxygen andα-FeOOH,while the anodic process was the iron dissolution.As Cl^(−)increased to 0.1 M,the steel tended to be activity dissolution.Due to the blocking effect of rust layer on the oxygen,the cathodic process transformed to the reduction ofα-FeOOH.After the solutions were deoxidized,the cathodic process was controlled by only rust reduction.Meanwhile,both the cathodic process and anodic process of NiCu steel corrosion were significantly inhibited.During the whole aerobic–anoxic immersion,the corrosion rate of NiCu steel increased with Cl^(−)concentration.It was not only related to the promotion of Cl^(−)on the anodic dissolution of steel,but also related to the cathodic reduction of moreα-FeOOH generated,which could accelerate the cathodic process. | Xin Wei Yupeng Sun Junhua Dong Nan Chen Qiying Ren Wei Ke | 2023 | Acta Metallurgica Sinica(English Letters)2023，36，5： | 0 |
