13D Positional and Quantitative Prediction of the Xiaoqinling Gold Ore Belt in Tongguan, Shaanxi, China显示文摘Quantitative prediction of deep orebody based on 3D visualization technology is of great significance in mineral exploration. Based on the 2D traditional quantitative predicting method, the geoanomaly theory and the mineral exploration model idea, we constructed 3D models of the topography, strata, structure, magmatite and prospecting engineering of the study area using the commercial 3D modeling software Micromine, delineated eight prospective areas and estimated the gold resources amount with methods of Abundance Estimation and Volume Estimation. Then, we compared and counted the known ore blocks and the predicted blocks, which quantitatively explains this prediction's validity. The results show that Xiaoqinling gold belt in Tongguan has convincing potential for gold development and utilization and the prediction method based on 3D visualization technology proves to be effective.CHEN Jianping SHI Rui CHEN Zhenping WANG Limei SUN Yan 2012Acta Geologica Sinica(English Edition)2012,86,3:14

3Syntheses and characterization of anti-thrombotic and anti-oxidative Gastrodin-modified polyurethane for vascular tissue engineering显示文摘Vascular grafts must avoid negative inflammatory responses and thrombogenesis to prohibit fibrotic deposition immediately upon implantation and promote the regeneration of small diameter blood vessels(<6 mm inner diameter).Here,polyurethane(PU)elastomers incorporating anti-coagulative and anti-inflammatory Gastrodin were fabricated.The films had inter-connected pores with porosities equal to or greater than 86%and pore sizes ranging from 250 to 400μm.Incorporation of Gastrodin into PU films resulted in desirable mechanical properties,hydrophilicity,swelling ratios and degradation rates without collapse.The released Gastrodin maintained bioactivity over 21 days as assessed by its anti-oxidative capability.The Gastrodin/PU had better anti-coagulation response(less observable BSA,fibrinogen and platelet adhesion/activation and suppressed clotting in whole blood).Red blood cell compatibility,measured by hemolysis,was greatly improved with 2Gastrodin/PU compared to other Gastrodin/PU groups.Notably,Gastrodin/PU upregulated anti-oxidant factors Nrf2 and HO-1 expression in H2O2 treated HUVECs,correlated with decreasing pro-inflammatory cytokines TNF-αand IL-1β in RAW 264.7 cells.Upon implantation in a subcutaneous pocket,PU was encapsulated by an obvious fibrous capsule,concurrent with a large amount of inflammatory cell infiltration,while Gastrodin/PU induced a thinner fibrous capsule,especially 2Gastrodin/PU.Further,enhanced adhesion and proliferation of HUVECs seeded onto films in vitro demonstrated that 2Gastrodin/PU could help cell recruitment,as evidenced by rapid host cell infiltration and substantial blood vessel formation in vivo.These results indicate that 2Gastrodin/PU has the potential to facilitate blood vessel regeneration,thus providing new insight into the development of clinically effective vascular grafts.Meng Zheng Jiazhi Guo Qing Li Jian Yang Yi Han Hongcai Yang Mali Yu Lianmei Zhong Di Lu Limei Li Lin Sun 2021Bioactive Materials2021,6,2:7

7Bio-inspired Superhydrophobic Self-healing Surfaces with Synergistic Anticorrosion Performance显示文摘The past decade has witnessed significant efforts in addressing the global metallic corrosion challenge,with a focus on avoiding or mitigating huge economic losses incurred by corrosion and on the development of protective coatings on metals.Herein,a synergistic anticorrosion coating with both superhydrophobicity and self-healing properties was reported,through a facile replica molding method by mixing the polyvinylidene fluoride(PVDF)matrix with nano-sized SiO2 particles and 2-mercaptobenzothiazole(MBT)loaded halloysites(HNTs).The surface exhibits robust self-cleaning behavior under harsh conditions and high liquid repellence to withstand the osmosis of corrosive ions.The self-healing performance of the coating,due to the introduction of MBT-loaded HNTs,enhances the anticorrosion capability,which is still valid once the protective layer is damaged.Potentiodynamic polarization(PDP)and Electrochemical Impedance Spectroscopy(EIS)measurements demonstrate that the synergetic effects in anticorrosion performances significantly enhance the long-term corrosion protection of metals.Hence,this type of dual-action coating may find unique applications in metal corrosion resistance where both super-repellency and self-healing properties are desired.Xiaona Yang Limei Tian Wei Wang Yong Fan Jiyu Sun Jie Zhao Luquan Ren 2020Journal of Bionic Engineering2020,17,6:4
8The relationships among aerosol optical depth, ice, phytoplankton and dimethylsulfide and the implication for future climate in the Greenland Sea显示文摘The sea-to-air flux of dimethylsulphide(DMS) is one of the major sources of marine biogenic aerosol, and can have an important radiative impact on climate, especially in the Arctic Ocean. Satellite-derived aerosol optical depth(AOD) is used as a proxy for aerosol burden which is dominated by biogenic aerosol during summer and autumn. The spring sea ice melt period is a strong source of aerosol precursors in the Arctic. However, high aerosol levels in early spring are likely related to advection of continental pollution from the south(Arctic haze).Higher AOD was generally registered in the southern part of the study region. Sea ice concentration(SIC) and AOD were positively correlated, while cloud cover(CLD) and AOD were negative correlation. The seasonal peaks of SIC and CLD were both one month ahead of the peak in AOD. There is a strong positive correlation between AOD and SIC. Melting ice is positively correlated with chlorophyll a(CHL) almost through March to September,but negatively correlated with AOD in spring and early summer. Elevated spring and early summer AOD most likely were influenced by combination of melting ice and higher spring wind in the region. The peak of DMS flux occurred in spring due to the elevated spring wind and more melting ice. DMS concentration and AOD were positively correlated with melting ice from March to May. Elevated AOD in early autumn was likely related to the emission of biogenic aerosols associated with phytoplankton synthesis of DMS. The DMS flux would increase more than triple by 2100 in the Greenland Sea. The significant increase of biogenic aerosols could offset the warming in the Greenland Sea.QU Bo GABRIC Albert J.

9MS1 is essential for male fertility by regulating the microsporocyte cell plate expansion in soybean显示文摘Male sterility is an essential trait in hybrid seed production,especially for monoclinous and autogamous food crops.Soybean male-sterile ms1 mutant has been known for more than 50 years and could be instrumental in making hybrid seeds.However,the gene responsible for the male-sterile phenotype has remained unknown.Here,we report the map-based cloning and characterization of the MS1 gene in soybean.MS1 encodes a kinesin protein and localizes to the nucleus,where it is required for the male meiotic cytokinesis after telophase Ⅱ.We further substantiated that MS1 colocalizes with microtubules and is essential for cell plate formation in soybean male gametogenesis through immunostaining.Both ms1 and CRISPR/Cas9 knockout mutants show complete male sterility but are otherwise phenotypically normal,making them perfect tools for producing hybrid seeds.The identification of MS1 has the practical potential for assembling the sterility system and speeding up hybrid soybean breeding.Xiaolong Fang Xiaoyuan Sun Xiangdong Yang Qing Li Chunjing Lin Jie Xu Wenjun Gong Yifan Wang Lu Liu Limei Zhao Baohui Liu Jun Qin Mengchen Zhang Chunbao Zhang Fanjiang Kong Meina Li 2021Science China(Life Sciences)2021,64,9:4
10Busuishengxue ranules mediate their effects upon non-severe aplastic anemia via mitogen-activated protein kinase/extracellular signal-regulated kinase pathway显示文摘OBJECTIVE:To observe the clinical efficacy of Busuishengxue granules on non-severe aplastic anemia(NSAA)and investigate its effect on the mitogen-activated protein kinase/extracellular signal-regulated kinase(MAPK/ERK)pathway.METHODS:Sixty NSAA patients were divided equally into two groups.Subjects in the experimental group were treated with Busuishengxue granules,and the control group with Zaizaoshengxue tablets.The treatment course was 6 months and cu-rative efficacy was compared between the two groups as well as with 10 healthy individuals.Flow cytometry(FCM)was used to detect the intracellular concentration of Ca2+([Ca2+]i).Western blotting was employed to detect the expression of enzymes in the MAPK/ERK pathway.RESULTS:The efficacy of Busuishengxue granules was significantly better than that of Zaizaoshengxue tablets(P<0.05).Before treatment,expression of JNK,phospho-ERK 1/2 and p-JNK was higher,and[Ca2+]i higher,than that of the control group(P<0.05).After treatment with Busuishengxue granules,expression of all enzymes related to signal transduction pathways in the blood cells of NSSA patients were altered to different degrees.CONCLUSION:Busuishengxue granules had a better effect with regard to improving symptom scores,increasing the number of blood leukocytes,and increasing hemoglobin levels than Zaizaoshengxue tablets,and they differed slightly in terms of increasing the number of platelets.Jinhuan Wang Feng Sun Weizheng Sun Yanli Yong Haitao Shi Sijia Liu Limei Liu 2014Journal of Traditional Chinese Medicine2014,34,1:3
11Dual-Fuel-Driven Bactericidal Micromotor显示文摘In this paper, we report fabrication of the bimetallic Janus microsphere, a magnesium microsphere with a silver surface coating, through thermal evaporation technique. Because of the Janus structure, this micromotor can be propelled in two different directions by the surface silver or magnesium ‘engine' and hydrogen peroxide or water fuel. In addition, due to the bactericidal property of silver, this autonomous micromotor is capable of killing bacteria in solution. As compared to the static one, the micromotor is able to kill the bacteria at a much faster rate(about nine times of that of the static one),demonstrating the superiority of the motion one. We thus believe that the micromotor shown in the current study is potentially attractive for the environmental hygiene applications.Ya Ge Mei Liu Limei Liu Yunyu Sun Hui Zhang Bin Dong 2016Nano-Micro Letters2016,8,2:3
12Novel Anti-fouling Strategies of Live and Dead Soft Corals(Sarcophyton trocheliophorum):Combined Physical and Chemical Mechanisms显示文摘At present,biomimetic antifouling research objects are mostly concentrated on the fast-moving marine organism,but the anti-fouling effect of the low-speed or static marine equipment is not obvious.This paper describes the anti-fouling mechanism of soft coral(Sarcophyton trocheliophorum),including the physical defense mechanism and the bactericidal ability of mucus and coral powder.As a sessile organisms,soft coral lacks escape mechanism.Therefore,the study on its antibacterial strategy is significant because it can provide theoretical guidance for static antifouling.Results showed that the live soft coral would molt in unfriendly environment,and the secreted mucus could defend themselves against fouling microorganism.Then,Liquid Chromatography-Mass Spectrometry(LC-MS)analysis was conducted to identify the bioactive compounds of the coral powder and mucus.Results revealed that both powder and mucus contained a wide variety of toxic components,which had bactericidal effects.Moreover,at the same concentration,the inhibitory effect of the main components on Gram-negative bacteria was stronger than that on positive bacteria.These findings enhance the understanding about the antifouling mechanism of soft coral and provide new ideas for design and prepare novel antifouling strategy to combat biofouling under static condition.Limei Tian E Jin Benli Yu Hang Sun Yangeng Shang Wei Bing 2020Journal of Bionic Engineering2020,17,4:2

15MALE STERILITY 3 encodes a plant homeodomain-finger protein for male fertility in soybean显示文摘Male-sterile plants are used in hybrid breeding to improve yield in soybean(Glycine max(L.)Merr.).Developing the capability to alter fertility under different environmental conditions could broaden germplasm resources and simplify hybrid production.However,molecular mechanisms potentially underlying such a system in soybean were unclear.Here,using positional cloning,we identified a gene,MALE STERILITY 3(MS3),which encodes a nuclear-localized protein containing a plant homeodomain(PHD)-finger domain.A spontaneous mutation in ms3 causing premature termination of MS3 translation and partial loss of the PHD-finger.Transgenetic analysis indicated that MS3 knockout resulted in nonfunctional pollen and no selfpollinated pods,and RNA-seq analysis revealed that MS3 affects the expression of genes associated with carbohydrate metabolism.Strikingly,the fertility of mutant ms3 can restore under longd conditions.The mutant could thus be used to create a new,more stable photoperiod-sensitive genic male sterility line for two-line hybrid seed production,with significant impact on hybrid breeding and production.Jingjing Hou Weiwei Fan Ruirui Ma Bing Li Zhihui Yuan Wenxuan Huang Yueying Wu Quan Hu Chunjing Lin Xingqi Zhao Bao Peng Limei Zhao Chunbao Zhang Lianjun Sun 2022Journal of Integrative Plant Biology2022,64,5:1
16Combined organic-inorganic fertilization builds higher stability of soil and root microbial networks than exclusive mineral or organic fertilization显示文摘Plant health and performance are highly dependent on the root microbiome.The impact of agricultural management on the soil microbiome has been studied extensively.However,a comprehensive understanding of how soil types and fertilization regimes affect both soil and root microbiome is still lacking,such as how fertilization regimes affect the root microbiome's stability,and whether it follows the same patterns as the soil microbiome.In this study,we carried out a longterm experiment to see how different soil types,plant varieties,and fertilizer regimens affected the soil and root bacterial communities.Our results revealed higher stability of microbial networks under combined organic-inorganic fertilization than those relied solely on inorganic or organic fertilization.The root microbiome variation was predominantly caused by total nitrogen,while the soil microbiome variation was primarily caused by pH and soil organic matter.Bacteroidetes and Firmicutes were major drivers when the soil was amended with organic fertilizer,but Actinobacteria was found to be enriched in the soil when the soil was treated with inorganic fertilizer.Our findings demonstrate how the soil and root microbiome respond to diverse fertilizing regimes,and hence contribute to a better understanding of smart fertilizer as a strategy for sustainable agriculture.Luhua Yang Renhua Sun Jungai Li Limei Zhai Huiling Cui Bingqian Fan Hongyuan Wang Hongbin Liu 2023Soil Ecology Letters2023,5,2:1
