| 1 | Introduction of rice chitinase gene into wheat via low energy Ar^+ beam implantation显示文摘A chitinase gene (RCH8) in plasmid vector pCAMBIA1308 was delivered into 3 wheat cultivars (Yangmai 158, Wan 9210, Wanmai 32) by low energy Ar+ beam-mediated method. Preliminary calli from treated mature embryos were first selected on hygromycin (Hm, 20 or 30 mg/L) containing medium. After the resistant calli formed, they were transferred to the regeneration medium with 10 or 20 mg/L Hm. All the three wheat varieties obtained trans-genie plants. PCR and PCR-Southern assays showed that most plants regenerated from the resistant calli were positive transgenic plants. Southern blot of the positive green plants confirmed stable integration of alien DNA into wheat genome. The plant transformation frequencies varied with the variety and ion dose implanted. Wanmai 32 possessed the highest transformation frequency, reaching 3.8% at a suitable implantation dose. The transformation frequency of Yangmai 158 and Wan 9210 varied from 0.5% to 2.5% and from 0.5% to 1.4%, respectively.

| 2 | The climate influence of anthropogenic land-use changes on near-surface wind energy potential in China显示文摘There is considerable interest in the potential impact of climate change on wind energy in China. The climate change of near-surface wind energy potential in China under the background of global warming and its association with anthropogenic land-use changes are investigated by calculating the difference in surface wind speeds between the NCEP/NCAR reanalysis data and the observations since the re- analysis dataset contains the influence of large-scale climate changes due to greenhouse gases, it is less sensitive to regional surface processes associated with land types. The surface wind data in this study consist of long-term observations from 604 Chinese Roution Meteorological Stations and the NCEP/NCAR reanalysis data from 1960―1999. The results suggest that the observed mean wind speeds significantly weakened and the near-surface wind power trended downward due to urbanization and other land-use changes in the last 40 years. The mean wind energy weakened by -3.84 W·m_(-2) per decade due to the influence of anthropogenic land-use change, which is close to the observed climate change (-4.51 W·m_(-2)/10 a). | LI Yan WANG Yuan CHU HuiYun TANG JianPing | 2008 | Chinese Science Bulletin2008,53,18: | 13 |
| 3 | Evolution and molecular epidemiology of foot-and-mouth disease virus in China显示文摘Foot-and-mouth disease (FMD),caused by foot-and-mouth disease virus (FMDV),is considered one of the most important viral diseases of cloven-hoofed animals,causing severe economic losses in affected regions of the world.Three serotypes (A,O,and Asia 1) of FMDV have been identified in China since 1958.In addition,the occurrence of novel subtypes within these serotypes has made the epidemiology of FMDV more complicated over the last few years.In this review,we summarize the history and the current epidemiological situation in China,genetic diversity (e.g.,quasispecies dynamics,antigenic heterogeneity,and functional constraints),intertypic recombination,and the evidence for positive selection of different FMDV serotypes.We also assess these genetic data to understand the origin,evolution,and transmission of FMDV,the findings of which may be useful in developing control measures for future epidemics. | BAI XingWen LI PingHua BAO HuiFang LIU ZaiXin LI Dong LU ZengJun CAO YiMei SHANG YouJun SHAO JunJun CHANG HuiYun LUO JianXun LIU XiangTao | 2011 | Chinese Science Bulletin2011,56,21: | 7 |
| 4 | Separating impacts of vegetation change and climate variability on streamflow using hydrological models together with vegetation data显示文摘Vegetation information is seldom considered in lumped conceptual rainfall-runoff models.This paper uses two modified rainfall-runoff models,the Xinanjiang-ET and SIMHYD-ET models in which vegetation leaf area index is incorporated,to investigate impacts of vegetation change and climate variability on streamflow in a Southern Australian catchment,the Crawford River experimental catchment,where Tasmanian blue gum plantations were introduced gradually from 1998 till 2005.The Xinanjiang-ET and SIMHYD-ET models incorporate remotely-sensed leaf area index(LAI) data obtained from the Advanced Very High Resolution Radiometer(AVHRR) on board NOAA polar orbiting satellites.Compared to the original versions,the Xinanjiang-ET and SIMHYD-ET models show marginal improvements in runoff simulations in the pre-plantation period(1882-1997).The calibrated Xinanjaing-ET and SIMHYD-ET models are then used to simulate plantation impact on streamflow in the post-plantation period.The total change in streamflow between the pre-plantation and post-plantation periods is 32.4 mm/a.The modelling results from the two models show that plantation reduces streamflow by 20.5 mm/a,and climate variability reduces streamflow by 11.9 mm/a.These results suggest that increase in plantations can reduce streamflow substantially,even more than climate variability. | LI HuiYun ZHANG YongQiang WANG BenDe | 2012 | Science China(Technological Sciences)2012,55,7: | 6 |
| 5 | Spatially Bandgap-Graded Mo S2(1-x)Se2x Homojunctions for Self-Powered Visible–Near-Infrared Phototransistors显示文摘Ternary transition metal dichalcogenide alloys with spatially graded bandgaps are an emerging class of two-dimensional materials with unique features,which opens up new potential for device applications.Here,visible–near-infrared and self-powered phototransistors based on spatially bandgap-graded MoS2(1−x)Se2x alloys,synthesized by a simple and controllable chemical solution deposition method,are reported.The graded bandgaps,arising from the spatial grading of Se composition and thickness within a single domain,are tuned from 1.83 to 1.73 eV,leading to the formation of a homojunction with a builtin electric field.Consequently,a strong and sensitive gate-modulated photovoltaic effect is demonstrated,enabling the homojunction phototransistors at zero bias to deliver a photoresponsivity of 311 mA W−1,a specific detectivity up to^10^11 Jones,and an on/off ratio up to^10^4.Remarkably,when illuminated by the lights ranging from 405 to 808 nm,the biased devices yield a champion photoresponsivity of 191.5 A W−1,a specific detectivity up to^1012 Jones,a photoconductive gain of 10^6–10^7,and a photoresponsive time in the order of^50 ms.These results provide a simple and competitive solution to the bandgap engineering of two-dimensional materials for device applications without the need for p–n junctions. | Hao Xu Juntong Zhu Guifu Zou Wei Liu Xiao Li Caihong Li Gyeong Hee Ryu Wenshuo Xu Xiaoyu Han Zhengxiao Guo Jamie HWarner Jiang Wu Huiyun Liu | 2020 | Nano-Micro Letters2020,12,2: | 4 |
| 6 | Research and application of flood detention modeling for ponds and small reservoirs based on remote sensing data显示文摘This paper proposes a method of small reservoir flood detention modeling that utilizes data from the American land resources satellite Landsat TM/ETM+. Precipitation and potential evapotranspiration are taken as the control conditions in this method on the basis of basin terrain classification. The objective of this method is to solve the question of a small-scale water conservancy project’s influence on flood forecasting precision, which can be used in the basin with multitudinous small reservoirs in the upstream region and can help estimate non-runoff data for small reservoir runoff. Taking the 20060826 flood as an example, the flood detention quantity of 19 small reservoirs is modeled. The results show that the absolute error of the total flood detention quantity is 0.2×10 4 m 3 , and the relative error is 0.12%. The flood detention quantity of small reservoirs in the entire basin is then modeled using this method, and the primary flood forecasting model is adjusted. After adjustment, the precision is significantly improved, with the relative error decreasing from 31.8% to 10.1%. | CAO MingLiang ZHOU HuiCheng ZHANG Chi ZHANG AiJing LI HuiYun YANG Yang | 2011 | Science China(Technological Sciences)2011,54,8: | 4 |
| 7 | Phytotoxicity of four herbicides on Ceratophyllum demersum,Vallisneria natans and Elodea nuttallii显示文摘The physiological effects of 4 herbicides(butachlor,quinclorac,bensulfuron-methyl and atrazine) on 3 submerged macrophytes(Ceratophyllum demersum,Vallisneria natans and Elodea nuttallii) were tested in laboratory.The variables of the relative growth rate and the photosynthetic pigment content showed that all of the tested herbicides affected the growth of the plants obviously,even at the lowest concentration(0.0001 mg/L).Except for the C.demersum treated with quinclorac at 0.005 and 0.01 mg/L,the relative growth rates of the plants were inhibited significantly(p < 0.01).Statistical analysis of chlorophyll a(Chl-a) contents was carried out with both the t-test and one-way ANOVA to determine the difference between the treatment and control.The results showed that Chl-a contents of the plants in all treatment groups were affected by herbicides significantly,except for the C.demersum treated with bensulfuron-methyl at 0.0005 mg/L.The decrease in Chla content was positively correlated to the dosage of the herbicides in most treatment groups.It was suggested that herbicides in water bodies might potentially affect the growth of aquatic macrophytes.Since the Chl-a content of submerged macrophytes responded to the stress of herbicides sensitively and directly,it could be used as a biomaker in environmental monitoring or in the ecological risk assessment of herbicide contamination. | PAN Huiyun,LI Xiaolu,XU Xiaohua,GAO Shixiang State Key Laboratory of Pollution Control and Resource Reuse,School of the Environment,Nanjing University,Nanjing 210093,China. | 2009 | Journal of Environmental Sciences2009,21,3: | 4 |

| 9 | Novel soybean peptide iglycin ameliorates insulin resistance of high-fat diet fed C57BL/6J mice and differentiated 3T3L1 adipocytes with improvement of insulin signaling and mitochondrial function显示文摘Soy consumption has been associated with potential health benefits in reducing chronic diseases.These physiological functions have been attributed to soy proteins or more commonly to bioactive peptides.Thus,more studies are required to identify these bioactive peptides,and elucidate their biological mechanisms of action.In the present study,a novel peptide iglycin was purifi ed from soybean seeds with a molecular mass of 3.88 k Da.Thereafter,iglycin reduced fasting blood glucose and restored insulin sensitivity of C57 BL/6 J mice on a high-fat diet with increased phosphorylation of insulin receptor substrate 1(IRS1)and AKT in adipose tissue.Furthermore,it improved glucose uptake,induced translocation of intracellular GLUT4 to plasma membrane and activation of insulin signaling in adipocytes under insulin-resistant condition.In addition,it decreased reactive oxygen species production,lipid peroxidation and inhibited adipocyte apoptosis with improved mitochondrial function as evidenced by up-regulation of succinate dehydrogenase activity,mitochondrial membrane potential and intracellular ATP store.These data suggested that iglycin ameliorated insulin resistance via activation of insulin signaling,which was associated with inhibition of oxidative stress,adipocyte apoptosis,and improvement of mitochondrial function. | Yinghuan Wu Ran Zhao Minxia Li Huiyun Li Zhengwang Chen Yanying Zhao | 2022 | Food Science and Human Wellness2022,11,6: | 3 |

| 11 | 1.3 μm InAs/GaAs quantum dot lasers on silicon with GaInP upper cladding layers显示文摘We report on the first electrically pumped continuous-wave(CW) In As/Ga As quantum dot(QD) laser grown on Si with a GaInP upper cladding layer. A QD laser structure with a Ga_(0.51)In_(0.49)P upper cladding layer and an Al_(0.53)Ga_(0.47)As lower cladding layer was directly grown on Si by metal–organic chemical vapor deposition. It demonstrates the postgrowth annealing effect on the QDs was relieved enough with the GaInP upper cladding layer grown at a low temperature of 550°C. Broad-stripe edge-emitting lasers with 2-mm cavity length and 15-μm stripe width were fabricated and characterized. Under CW operation, room-temperature lasing at ~1.3 μm has been achieved with a threshold density of 737 A∕cm^2 and a single-facet output power of 21.8 mW. | JUN WANG HAIYANG HU HAWING YIN YIMING BAI JIAN LI XIN WEI YUANYUAN LIU YONGQING HUANG XIAOMIN REN HUIYUN LIU | 2018 | Photonics Research2018,6,4: | 2 |
| 12 | Chitosan and β-cyclodextrin Microspheres as Pulmonary Sustained Delivery Systems显示文摘Chitosan andβ-cyclodextrin were used to prepare microspheres with theophylline for pulmonary delivery by spray drying method.The characteristics,mucociliotoxicity,permeation rate and drug release were studied.The drug entrapments of microspheresⅠ,ⅡandⅢ were from 35.70%to 21.09% and 13.33%,while yields and encapsulation efficiencies were higher than 45% and about 90% respectively. The microspheres possessed low tap densities(0.34-0.48 g/cm3),appropriate diameters(3.35-3.94μm)and theoretical aerodynamics diameters(2.20-3.04μm).SEM images showed the microspheres were spherical with smooth or wrinkled surface surfaces.FT-IR demonstrated theophylline had formed hydrogen bonds with chitosan and β-cyclodextrin.The microspheres could effectively reduce the ciliotoxicity and easy to penetrate the memberine.The in vitro release of the microspheres was related to the ratio of drug/polymer and microspheresⅡ had a prolong release,providing the release of 72.00%in 12 h.The results suggestes that chitosan/β-cyclodextrin microspheresⅡare a promising carrier as sustained release for pulmonary delivery. | ZHANG Weifen CHEN Xiguang LI Piwu HE Qiangzhi ZHOU Huiyun CHA Dongsu | 2008 | Journal of Wuhan University of Technology(Materials Science)2008,23,4: | 2 |
| 13 | VGLUT3 neurons in median raphe control the efficacy of spatial memory retrieval via ETV4 regulation of VGLUT3 transcription显示文摘The raphe nucleus is critical for feeding, rewarding and memory. However, how the heterogenous raphe neurons are molecularly and structurally organized to engage their divergent functions remains unknown. Here, we genetically target a subset of neurons expressing VGLUT3. VGLUT3 neurons control the efficacy of spatial memory retrieval by synapsing directly with parvalbumin-expressing GABA interneurons(PGIs) in the dentate gyrus. In a mouse model of Alzheimer's disease(AD mice),VGLUT3→PGIs synaptic transmission is impaired by ETV4 inhibition of VGLUT3 transcription. ETV4 binds to a promoter region of VGLUT3 and activates VGLUT3 transcription in VGLUT3 neurons. Strengthening VGLUT3→PGIs synaptic transmission by ETV4 activation of VGLUT3 transcription upscales the efficacy of spatial memory retrieval in AD mice. This study reports a novel circuit and molecular mechanism underlying the efficacy of spatial memory retrieval via ETV4 inhibition of VGLUT3 transcription and hence provides a promising target for therapeutic intervention of the disease progression. | Aodi He Chen Zhang Xiao Ke Yao Yi Quntao Yu Tongmei Zhang Hongyan Yu Huiyun Du Hao Li Qing Tian Ling-Qiang Zhu Youming Lu | 2022 | Science China(Life Sciences)2022,65,8: | 2 |
| 14 | A regeneration system using cotyledons and cotyledonary node explants of Toona ciliata显示文摘We used the cotyledons and cotyledonary nodes of Toona ciliata(Chinese mahogany)as explants to examine callus and adventitious shoot induction when exposed to different ratios of hormones.We also investigated the effects of seedling age,inoculation method,and genotype on the efficient regeneration of T.ciliata.The results showed that different genotypes exhibited significantly different callus induction efficiency.The cotyledons and cotyledonary nodes of 20-day seedlings inoculated onto MS medium with 0.5 mg/L 6-benzylaminopurine(6-BA),0.5 mg/L kinetin(KT)and 0.05 mg/L 1-naphthylacetic acid(NAA)achieved a greater regeneration rate than did other concentrations of cytokinin and auxin.The numbers of shoots per cotyledon and cotyledonary node explant were 7.33 and 6.67.The optimal inoculation method for cotyledons was that the distal end of the explants was placed in contact with the medium.The optimal adventitious shoot differentiation medium for cotyledon explants was MS medium containing 0.3 mg/L 6-BA and 0.2 mg/L NAA,producing a 3.4 cm height of shoot on average.This study established an efficient regeneration system for T.ciliata with cotyledons and cotyledonary nodes as explants. | Huiyun Song Wenmai Mao Yuanyuan Shang Wei Zhou Pei Li Xiaoyang Chen | 2021 | Journal of Forestry Research2021,32,3: | 2 |

| 17 | Chronic hypoperfusion due to intracranial large artery stenosis is not associated with cerebralβ-amyloid deposition and brain atrophy显示文摘Background:Insufficient cerebral perfusion is suggested to play a role in the development of Alzheimer disease(AD).However,there is a lack of direct evidence indicating whether hypoperfusion causes or aggravates AD pathology.We investigated the effect of chronic cerebral hypoperfusion on AD-related pathology in humans.Methods:We enrolled a group of cognitively normal patients(median age:64 years)with unilateral chronic cerebral hypoperfusion.Regions of interest with the most pronounced hypoperfusion changes were chosen in the hypoperfused region and were then mirrored in the contralateral hemisphere to create a control region with normal perfusion.11C-Pittsburgh compound-positron emission tomography standard uptake ratios and brain atrophy indices were calculated from the computed tomography images of each patient.Results:The median age of the 10 participants,consisting of 4 males and 6 females,was 64 years(47-76 years).We found that there were no differences in standard uptake ratios of the cortex(volume of interest[VOI]:P=0.721,region of interest[ROI]:P=0.241)and grey/white ratio(VOI:P=0.333,ROI:P=0.445)and brain atrophy indices(Bicaudate,Bifrontal,Evans,Cella,Cella media,and Ventricular index,P>0.05)between the hypoperfused regions and contralateral normally perfused regions in patients with unilateral chronic cerebral hypoperfusion.Conclusion:Our findings suggest that chronic hypoperfusion due to large vessel stenosis may not directly induce cerebralβ-amyloid deposition and neurodegeneration in humans. | Dongyu Fan Huiyun Li Dongwan Chen Yang Chen Xu Yi Heng Yang Qianqian Shi Fangyang Jiao Yi Tang Qiming Li Fangyang Wang Shunan Wang Rongbing Jin Fan Zeng Yanjiang Wang | 2022 | Chinese Medical Journal2022,,5: | 1 |
