| 1 | Using specific secondary metabolites as markers to evaluate allelopathic potentials of rice varieties and individual plants显示文摘It is a key of the breeding of ailelopathic rice cultivars to evaluate and screen few accessions with ailelopathic traits from numerous rice accessions and individual plants. Rice varieties and individual plants with ailelopathic traits demonstrated their ailelopathic effects by producing and releasing specific secondary metabolites into environment. Therefore, using specific secondary metabolites as markers, the ailelopathic potentials of rice varieties and individual plants could be evaluated by HPLC. The ailelopathic potentials of 3000 rice accessions and some individual plants of F3 and F4 were evaluated by this method in 1 a. If these accessions and plants were evaluated by the traditional method in the field, it would take more than 10 a, furthermore, the breeding process of ailelopathic rice cultivars would be directed and monitored by this method. Isolation and structural identification of specific secondary metabolites was done by LC/MS coupling 1H and 13C NMR. It revealed that allelochemicals | KONG Chuihua XU Xiaohua HU Fei CHEN Xionghui LING Bing TAN Zhongwen | 2002 | Chinese Science Bulletin2002，47，10： | 17 |
| 2 | Comparison of ground truth location of earthquake from InSAR and from ambient seismic noise: A case study of the 1998 Zhangbei earthquake显示文摘Because ambient seismic noise provides estimated Green's function (EGF) between two sites with high accuracy, Rayleigh wave propagation along the path connecting the two sites is well resolved. Therefore, earthquakes which are close to one seismic station can be well located with calibration extracting from EGF. We test two algorithms in locating the 1998 Zhangbei earthquake, one algorithm is waveform-based, and the other is traveltime-based. We first compute EGF between station ZHB (a station about 40 km away from the epicenter) and five IC/IRIS stations. With the waveform-based approach, we calculate 1D synthetic single-force Green's functions between ZHB and other four stations, and obtain traveltime corrections by correlating synthetic Green's functions with EGFs in period band of 10-30 s. Then we locate the earthquake by minimizing the differential travel times between observed earthquake waveform and the 1D synthetic earthquake waveforms computed with focal mechanism provided by Global CMT after traveltime correction from EGFs. This waveform-based approach yields a location which error is about 13 km away from the location observed with InSAR. With the traveltime-based approach, we begin with measuring group velocity from EGFs as well as group arrival time on observed earthquake waveforms, and then locate the earthquake by minimizing the difference between observed group arrival time and arrival time measured on EGFs. This traveltime-based approach yields accuracy of 3 km, Therefore it is feasible to achieve GT5 (ground truth location with accuracy 5 km) with ambient seismic noises. The less accuracy of the waveform-based approach was mainly caused by uncertainty of focal mechanism. | Jun Xie Xiangfang Zeng Weiwen Chen Zhongwen Zhan | 2011 | Earthquake Science2011，24，2： | 7 |
| 3 | Immunity-and-matrix-regulatory cells derived from human embryonic stem cells safely and effectively treat mouse lung injury and fibrosis显示文摘Lung injury and fibrosis represent the most significant outcomes of severe and acute lung disorders,including COVID-19.However,there are still no effective drugs to treat lung injury and fibrosis.In this study,we report the generation of clinical-grade human embryonic stem cells(hESCs)-derived immunity-and matrix-regulatory cells(IMRCs)produced under good manufacturing practice requirements,that can treat lung injury and fibrosis in vivo.We generate IMRCs by sequentially differentiating hESCs with serum-free reagents.IMRCs possess a unique gene expression profile distinct from that of umbilical cord mesenchymal stem cells(UCMSCs),such as higher expression levels of proliferative,immunomodulatory and anti-fibrotic genes.Moreover,intravenous delivery of IMRCs inhibits both pulmonary inflammation and fibrosis in mouse models of lung injury,and significantly improves the survival rate of the recipient mice in a dose-dependent manner,likely through paracrine regulatory mechanisms.IMRCs are superior to both primary UCMSCs and the FDA-approved drug pirfenidone,with an excellent efficacy and safety profile in mice and monkeys.In light of public health crises involving pneumonia,acute lung injury and acute respiratory distress syndrome,our findings suggest that IMRCs are ready for clinical trials on lung disorders. | Jun Wu Dingyun Song Zhongwen Li Baojie Guo Yani Xiao Wenjing Liu Lingmin Liang Chunjing Feng Tingting Gao Yanxia Chen Ying Li Zai Wang Jianyan Wen Shengnan Yang Peipei Liu Lei Wang Yukai Wang Liang Peng Glyn Nigel Stacey Zheng Hu Guihai Feng Wei Li Yan Huo Ronghua Jin Ng Shyh-Chang Qi Zhou Liu Wang Baoyang Hu Huaping Dai Jie Hao | 2020 | Cell Research2020，30，9： | 7 |
| 4 | In vitro biological effects of magnetic nanoparticles显示文摘Magnetic nanoparticles (MNPs) have great potential for a wide use in various biomedical applications due to their unusual properties. It is critical for many applications that the biological effects of nanoparticles are studied in depth. To date, many disparate results can be found in the literature regarding nanoparticle-biological factors interactions. This review highlights recent developments in this field with particular focuses on in vitro MNPs-cell interactions. The effect of MNPs properties on cellular uptake and cytotoxicity evaluation of MNPs were discussed. Some employed methods are also included. Moreover, nanoparticle-cell interactions are mediated by the presence of proteins absorbed from biological fluids on the nanoparticle. Many questions remain on the effect of nanoparticle surface (in addition to nanoparticle size) on protein adsorption. We review papers related to this point too. | LI Yan CHEN ZhongWen GU Ning | 2012 | Chinese Science Bulletin2012，57，31： | 5 |
| 5 | Microstructure and magnetic performance of Ni-substituted high density MnZn ferrite显示文摘The effects of NiO on microstructure and magnetic properties of Mn-Zn ferrite with a nominal composition of Zn0.32Mn0.60-xNixFe2.08O4 were investigated. The calcined powder of Mn-Zn ferrite was characterized by X-ray diffraction (XRD), the fracture surface of Mn-Zn ferrite was checked by scanning electronic microscope (SEM), and then the magnetic properties were measured. As a result, the substitution of Ni can cause the crystal lattice constant of MnZn ferrite to decline, and the grain size to decrease, therefore improve the magnetic performance of MnZn ferrite whose density exceeds 5.0 g·cm-3. | YU Zhong LAN Zhongwen CHEN Shengming SUN Yueming SUN Ke | 2006 | Rare Metals2006，25，z1： | 3 |
| 6 | Effect of sintering process on microstructure and magnetic properties of high frequency power ferrite显示文摘An oxide ceramic process was adopted to prepare high frequency manganese-zinc (MnZn) power ferrite. In combination with the microstructure analysis of material, the influences of sintering process on initial permeability (μi) and high frequency loss in unit volume (Pcv) of MnZn power ferrite were investigated. The results show that in order to obtain fine microstructure and high frequency properties, the preferable sintering temperature and atmosphere are 1230 ℃ and oxygen partial pressure (PO2) of 4%, respectively. | SUN Ke LAN Zhongwen CHEN Shengming SUN Yueming YU Zhong | 2006 | Rare Metals2006，25，z1： | 3 |

| 11 | Potential prebiotic effects of nonabsorptive components of Keemun and Dianhong black tea:an in vitro study显示文摘Black tea is a healthy and popular tea beverage.However,its main bioactive compounds(theaflavins and thearubigins)are not easily absorbed.The aim of this study was to investigate the modulation of intestinal microbiota by the nonabsorptive components of Keemun black tea(KBT)and Dianhong black tea(DBT),and fructooligosaccharide(FOS)was selected for use in the control group.KBT,DBT,and FOS significantly increased total short-chain acid production.Specifically,FOS treatment predominantly increased the production of acetic acids and black tea treatments increased the production of acetic,propionic,and butyric acids at similar rates.Moreover,FOS exerted a strong bifidogenic effect after 24 h of fermentation;KBT and DBT increased the abundance of the beneficial genus Bacteroides and Roseburia.In summary,the nonabsorptive components of KBT and DBT could serve as novel prebiotics,the underlying mechanisms of which are quite different from those of FOS. | Wenjing Liao Wenjiao Li Suyu Liu Dong Tang Yunxi Chen Yijun Wang Zhongwen Xie Jinbao Huang | 2022 | Food Science and Human Wellness2022，11，3： | 1 |
