1BZR1 Family Transcription Factors Function Redundantly and Indispensably in BR Signaling but Exhibit BRI1-Independent Function in Regulating Anther Development in Arabidopsis显示文摘BRASSINAZOLE-RESISTANT 1 family proteins(BZRs)are central transcription factors that govern brassinosteroid(BR)-regulated gene expression and plant growth.However,it is unclear whether there exists a BZR-independent pathway that mediates BR signaling.In this study,we found that disruption of all BZRs in Arabidopsis generated a hextuple mutant(bzr-h)displaying vegetative growth phenotypes that were almost identical to those of the null mutant of three BR receptors,bri1brl1brl3(bri-t).By RNA sequencing,we found that global gene expression in bzr-h was unaffected by 2 h of BR treatment.The anthers of bzr-h plants were loculeless,but a similar phenotype was not observed in bri-t,suggesting that BZRs have a BR signaling-independent regulatory role in anther development.By real-time PCR and in situ hybridization,we found that the expression of SPOROCYTELESS(SPL),which encodes a transcription factor essential for anther locule development,was barely detectable in bzr-h,suggesting that BZRs regulate locule development by affecting SPL expression.Our findings reveal that BZRs are indispensable transcription factors required for both BR signaling and anther locule development,providing new insight into the molecular mechanisms underlying the microsporogenesis in Arabidopsis.Lian-Ge Chen Zhihua Gao Zhiying Zhao Xinye Liu Yongpeng Li Yuxiang Zhang Xigang Liu Yu Sun Wenqiang Tang 2019Molecular Plant2019,12,10:11
2Synthesis of MOR/SAPO-11 Composite Molecular Sieve via Seed Crystallization for n-Alkane Hydroisomerization显示文摘n-Alkane isomerization is a critical reaction that can affect parameters in oil refining, such as the gasoline octane number and diesel oil solidifying point. In this study, a catalyst support, mordenite (MOR)/silicoaluminophosphate (SAPO)-11 composite zeolite with core/shell structure, was synthesized by hydrothermal method with MOR acting as the seed for crystallization. The crystal structure, elemental composition, surface area, pore volume, and acidity of the catalyst was thoroughly characterized. In addition, the catalytic performance of the as-obtained Pt/MOR/SAPO-11 in the hydroisomerization of n-dodecane was tested. The results indicated that the properties and catalytic performance of the composite molecular sieve were quite different from those of the pure zeolites and physical mixture of MOR and SAPO-11 (MOR+SAPO-11). Compared with the physical mixture, MOR and SAPO-11 were more tightly bound in MOR/SAPO-11 because of chemical bonding. Moreover, the acidity and pore structure were favorable to the catalytic hydroisomerization of n-dodecane. Pt/MOR/SAPO-11 exhibited higher isomerization activity than the Pt-loaded pristine MOR and MOR+SAPO-11. Thus, the core-shell composite molecular sieve has promising industrial applications as the catalyst support.Sun Na Wang Haiyan Ma Yuxiang Yang Zhanxu Kang Lei 2019China Petroleum Processing & Petrochemical Technology2019,21,2:6
3Indole-3-propionic Acid-aggravated CCl_(4)-induced Liver Fibrosis via the TGF-β1/Smads Signaling Pathway显示文摘Background and Aims:The pathogenesis of liver fibrosis involves liver damage,inflammation,oxidative stress,and intestinal dysfunction.Indole-3-propionic acid(IPA)has been demonstrated to have antioxidant,anti-inflammatory and anticancer activities,and a role in maintaining gut homeostasis.The current study aimed to investigate the role of IPA in carbon tetrachloride(CCl4)-induced liver fibrosis and explore the underlying mechanisms.Methods:The liver fibrosis model was established in male C57BL/6 mice by intraperitoneal injection of CCl4 twice weekly.IPA intervention was made orally(20 mg/kg daily).The degree of liver injury and fibrosis were assessed by serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),and histopathology.Enzyme-linked immunosorbent assay and quantitative real-time polymerase chain reaction(qPCR)were used to detect the inflammatory cytokines.The malondialdehyde(MDA),glutathione,glutathione peroxidase,superoxide dismutase,and catalase were determined via commercial kits.Hepatocyte apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay.The expression of mRNA and protein was assayed by qPCR,Western blotting,or immunohistochemical staining.Results:After IPA treatment,the ALT and AST,apoptotic cells,and pro-inflammatory factor levels were enhanced significantly.Moreover,IPA intervention up-regulated the expression of collagen I,α-smooth muscle actin,tissue inhibitor of matrix metalloproteinase-1,matrix metalloproteinase-2,transforming growth factor-β1(TGF-β1),Smad3,and phosphorylated-Smad2/3.Additionally,IPA intervention did not affect the MDA level.Attractively,the administration of IPA remodeled the gut flora structure.Conclusions:IPA aggravated CCl_(4)-induced liver damage and fibrosis by activating HSCs via the TGF-β1/Smads signaling pathway.Fei Liu Changfeng Sun Yuanfang Chen Fei Du Yuxiang Yang Gang Wu 2021Journal of Clinical and Translational Hepatology2021,9,6:5
4Protective effect of oxysophoridine on cerebral ischemia/reperfusion injury in mice显示文摘Oxysophoridine, a new alkaloid extracted from Sophora alopecuroides L., has been shown to have a protective effect against ischemic brain damage. In this study, a focal cerebral ischemia/reperfusion injury model was established using middle cerebral artery occlusion in mice. Both 62.5, 125, and 250 mg/kg oxysophoridine, via intraperitoneal injection, and 6 mg/kg nimodipine, via intragastric administration, were administered daily for 7 days before modeling. After 24 hours of reperfusion, mice were tested for neurological deficit, cerebral infarct size was assessed and brain tissue was collected. Results showed that oxysophoridine at 125, 250 mg/kg and 6 mg/kg nimodipine could reduce neurological deficit scores, cerebral infarct size and brain water content in mice. These results provided evidence that oxysophoridine plays a protective role in cerebral ischemia/reperfusion injury. In addition, oxysophoridine at 62.5, 125, and 250 mg/kg and 6 mg/kg nimodipine increased adenosine-triphosphate content, and decreased malondialdehyde and nitric oxide content. These compounds enhanced the activities of glutathione-peroxidase, superoxide dismutase, catalase, and lactate dehydrogenase, and decreased the activity of nitric oxide synthase. Protein and mRNA expression levels of N-methyl-D-aspartate receptor subunit NR1 were markedly inhibited in the presence of 250 mg/kg oxysophoridine and 6 mg/kg nimodipine. Our experimental findings indicated that oxysophoridine has a neuroprotective effect against cerebral ischemia/reperfusion injury in mice, and that the effect may be due to its ability to inhibit oxidative stress and expression of the N-methyl-D-aspartate receptor subunit NR1.Hongbo Wang Yuxiang Li Ning Jiang Xiaoping Chen Yi Zhang Kuai Zhang Tengfei Wang Yinju Hao Lin Ma Chengjun Zhao Yanrong Wang Tao Sun Jianqiang Yu 2013Neural Regeneration Research2013,8,15:5
5Expression Analysis of Genes Related to Auxin Metabolism at Different Growth Stages of Pak Choi显示文摘Pak choi is a low-temperature vernalized plant that readily undergoes premature bolting during spring, but little is known about the governing molecular regulation of vernalization. In order to enhance our understanding of mechanism about premature bolting, we discussed the relationship between auxin(indole-3-acetic acid, IAA) and flowering of pak choi. During vernalization, hormone metabolism is an important regulatory pathway, and IAA plays a specific role. IAA metabolism has been studied in Arabidopsis thaliana and other plants, but not in pak choi. In this paper, the IAA content in pak choi shoot apices during vernalization and different growth stages was compared. The IAA content decreased significantly after low-temperature treatment(4 °C) and then increased rapidly during vegetative growth. During floral bud initiation,the IAA content decreased rapidly and was the lowest. Expressions of genes encoding key IAA metabolic enzymes were analyzed, and a major synthetase-encoding gene was downregulated, while a key degrading enzyme-encoding gene was upregulated during each comparison period,resulting in decreased IAA content. Expressions of four genes(Bra034975, Bra030246, Bra012239 and Bra040296) were consistent with changes in the IAA content. The functions of differentially expressed genes(DEGs) were analyzed, and 15 DEGs were found to be related to IAA metabolism.The findings illuminated the molecular mechanism regulating IAA content during vernalization in pak choi.Yuxiang Hou Xueting Wang Zhujun Zhu Mengxia Sun Meilan Li Leiping Hou 2020Horticultural Plant Journal2020,6,1:4
6A Predictive 6G Network with Environment Sensing Enhancement:From Radio Wave Propagation Perspective显示文摘In order to support the future digital society,sixth generation(6G)network faces the challenge to work efficiently and flexibly in a wider range of scenarios.The traditional way of system design is to sequentially get the electromagnetic wave propagation model of typical scenarios firstly and then do the network design by simulation offline,which obviously leads to a 6G network lacking of adaptation to dynamic environments.Recently,with the aid of sensing enhancement,more environment information can be obtained.Based on this,from radio wave propagation perspective,we propose a predictive 6G network with environment sensing enhancement,the electromagnetic wave propagation characteristics prediction enabled network(EWave Net),to further release the potential of 6G.To this end,a prediction plane is created to sense,predict and utilize the physical environment information in EWave Net to realize the electromagnetic wave propagation characteristics prediction timely.A two-level closed feedback workflow is also designed to enhance the sensing and prediction ability for EWave Net.Several promising application cases of EWave Net are analyzed and the open issues to achieve this goal are addressed finally.Gaofeng Nie Jianhua Zhang Yuxiang Zhang Li Yu Zhen Zhang Yutong Sun Lei Tian Qixing Wang Liang Xia 2022China Communications2022,19,6:4
7Hippocampal overexpression of TREM2 ameliorates high fat diet induced cognitive impairment and modulates phenotypic polarization of the microglia显示文摘Type 2 diabetes mellitus(T2DM)and Alzheimer's disease(AD)share several common pathophysiological features.Rare variants of triggering receptor expressed on myeloid cells 2(TREM2)increase the risk of developing AD,suggesting the involvement of TREM2 and innate immunity in AD development.It is still unknown whether TREM2 is related to cognitive impairment in T2DM.Here,we investigated the effects of the hippocampal overexpression of TREM2 on cognitive in long-term high-fat diet(HFD)-fed mice.Male C57BL/6J mice were maintained on HFD for 50 weeks.TREM2 was overexpressed in the hippocampus 36 weeks after HFD feeding using adeno-associated virus vector(AAV)-mediated gene delivery.The results showed that the HFD feeding induced rapid and persistent weight gain,glucose intolerance and significant impairments in learning and memory.Compared with AAV-con,AAV-TREM2 significantly ameliorated cognitive impairment without altering body weight and glucose homeostasis in HFD mice.The overexpression of TREM2 upregulated the synaptic proteins spinophilin,PSD95 and synaptophysin,suggesting the improvement in synaptic transmission.Dendritic complexity and spine density in the CA1 region were rescued after TREM2 overexpression.Furthermore,TREM2 markedly increased the number of iba-1/Arg-1-positive microglia in the hippocampus,suppressed neuroinflammation and microglial activation.In sum,hippocampal TREM2 plays an important role in improving HFD-induced cognitive dysfunction and promoting microglial polarization towards the M2 anti-inflammatory phenotype.Our study also suggests that TREM2 might be a novel target for the intervention of obesity/diabetes-associated cognitive decline.Min Wu Maolin Liao Rongfeng Huang Chunxiu Chen Tian Tian Hongying Wang Jiayu Li Jibin Li Yuxiang Sun Chaodong Wu Qifu Li Xiaoqiu Xiao 2022Genes & Diseases2022,9,2:4
8High-performance all-polymer solar cells enabled by a novel low bandgap non-fully conjugated polymer acceptor显示文摘The non-fully conjugated polymer as a new class of acceptor materials has shown some advantages over its small molecular counterpart when used in photoactive layers for all-polymer solar cells(all-PSCs),despite a low power conversion efficiency(PCE)caused by its narrow absorption spectra.Herein,a novel non-fully conjugated polymer acceptor PFY-2TS with a low bandgap of~1.40 eV was developed,via polymerizing a largeπ-fused small molecule acceptor(SMA)building block(namely YBO)with a non-conjugated thioalkyl linkage.Compared with its precursor YBO,PFY-2TS retains a similar low bandgap but a higher LUMO level.Moreover,compared with the structural analog of YBO-based fully conjugated polymer acceptor PFY-DTC,PFY-2TS shows a similar absorption spectrum and electron mobility,but significantly different molecular crystallinity and aggregation properties,which results in optimal blend morphology with a polymer donor PBDB-T and physical processes of the device in all-PSCs.As a result,PFY-2TS-based all-PSCs achieved a PCE of 12.31%with a small energy loss of 0.56 eV enabled by the reduced non-radiative energy loss(0.24 eV),which is better than that of 11.08%for the PFY-DTC-based ones.Our work clearly demonstrated that non-fully conjugated polymers as a new class of acceptor materials are very promising for the development of high-performance all-PSCs.Qunping Fan Ruijie Ma Tao Liu Jianwei Yu Yiqun Xiao Wenyan Su Guilong Cai Yuxiang Li Wenhong Peng Tao Guo Zhenghui Luo Huiliang Sun Lintao Hou Weiguo Zhu Xinhui Lu Feng Gao Ellen Moons Donghong Yu He Yan Ergang Wang 2021Science China Chemistry2021,64,8:3
9Novel magnetic silk fibroin scaffolds with delayed degradation for potential long-distance vascular repair显示文摘Although with the good biological properties,silk fibroin(SF)is immensely restrained in long-distance vascular defect repair due to its relatively fast degradation and inferior mechanical properties.It is necessary to construct a multifunctional composite scaffold based on SF.In this study,a novel magnetic SF scaffold(MSFCs)was prepared by an improved infiltration method.Compared with SF scaffold(SFC),MSFCs were found to have better crystallinity,magnetocaloric properties,and mechanical strength,which was ascribed to the rational introduction of iron-based magnetic nanoparticles(MNPs).Moreover,in vivo and in vitro experiments demonstrated that the degradation of MSFCs was significantly extended.The mechanism of delayed degradation was correlated with the dual effect that was the newly formed hydrogen bonds between SFC and MNPs and the complexing to tyrosine(Try)to inhibit hydrolase by internal iron atoms.Besides,theβ-crystallization of protein in MSFCs was increased with the rise of iron concentration,proving the beneficial effect after MNPS doped.Furthermore,although macrophages could phagocytose the released MNPs,it did not affect their function,and even a reasonable level might cause some cytokines to be upregulated.Finally,in vitro and in vivo studies demonstrated that MSFCs showed excellent biocompatibility and the growth promotion effect on CD34-labeled vascular endothelial cells(VECs).In conclusion,we confirm that the doping of MNPs can significantly reduce the degradation of SFC and thus provide an innovative perspective of multifunctional biocomposites for tissue engineering.Xin Liu Yuxiang Sun Bo Chen Yan Li Peng Zhu Peng Wang Sen Yan Yao Li Fang Yang Ning Gu 2022Bioactive Materials2022,7,1:3
10The effects of portable cooling systems on thermal comfort and work performance in a hot environment显示文摘There are some special spaces in which there is no air conditioning or the people are in move,thus exposing people to a hot environment.In this study,portable cooling systems were proposed and their effects on thermal comfort and work performance were investigated at an air temperature of 32°C.Four conditions were established:cool air towards breathing zone(A),chest and back cooling(B)#combined cooling(C)and no cooling(D).Twenty-eight subjects were exposed to the four conditions in a counterbalanced order.During each exposure they performed tasks and made subjective assessments,while multiple physiological parameters were measured.Compared with no cooling(D),cool air towards breathing zone(A)and chest and back cooling(B)improved work performance by 17.5%and 19.25%,respectively,while decreased the subjects'thermal sensation,skin temperature,and heart rate.When the two cooling systems were combined(C),larger improvements in thermal comfort and work performance were achieved than no cooling(D);the mean thermal sensation rating decreased from 2.4 to 0.7;work performance increased by up to 33%,and physiological parameters including skin temperature,pulse,heart rate and salivary alpha-amylase significantly decreased.The present results suggest that the proposed portable cooling systems could maintain thermal comfort and work performance in a hot environment,while potentially improve air quality for some special spaces.Jieyu Tang Yu Liu Hui Du Li Lan Yuxiang Sun Jialin Wu 2021Building Simulation2021,14,6:2
11Amniotic Membrane Transplantation for Conjunctival Tumor显示文摘Purpose: To evaluate the possibility of amniotic membrane transplantation (AMT) for the treatment of conjunctival tumor.Methods: Preserved AMT was performed in 26 patients (26 eyes) with conjunctival tumor, including 9 eyes (34.62%) with malignant tumor (conjunctival malignant melanoma,corneal and conjunctival squamous cell carcinoma, conjunctival lymphoma), 17 eyes(65.38%) with benign tumor(conjunctival papilloma, conjunctival dermoid tumor, conjunctival nevus, hemangioma etc.).Result: All the patients are followed up for 1 ~53 months. No acute rejection was observed after preserved AMT. Ideal healing was found in conjunctiva wound.Conclusion: Preserved AMT is a very effective method to repair wound after giant conjunctival tumor operation. Complete removal of tumor and perfect fixation are the key of ocular surface reconstruction.Zhicong Chen, Jianhua Yan, Huasheng Yang, Zhongyao Wu Youjian Pang, Shiming Ai, Yuxiang Mao Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou 510060, China 2003Eye Science2003,19,3:2
12Cellulose derived biochar:Preparation,characterization and Benzo[α]pyrene adsorption capacity显示文摘Edible oil is prone to be contaminated by Benzo[a]pyrene(BaP)during production and processing.Adsorption is an important technology for the removal of BaP from edible oil,and biochar as a new type of adsorbent for the treatment BaP has received extensive attention.In this study,we prepared unmodified biochar and ZnCl_(2)-modified biochar from sesame straw cellulose(SSB and SSZ)and sesame capsule cellulose(SCB and SCZ),carried out structure characterization by Fourier Transform Infrared(FT-IR),Brunauer-Emmett-Teller(BET)and Scanning Electron Microscope(SEM),and finally evaluated their potential effectiveness in BaP removal from sesame oil.FT-IR results revealed that SSZ and SCZ showed higher peak intensities,indicating that they could provide more active sites for adsorption.The results of XRD presented that SSZ and SCZ had a higher graphitization degree than the unmodified biochar.SEM results showed that the SSZ and SCZ had more complex pore structure,which is beneficial to adsorption.BET analysis results showed that SSZ and SCZ had a higher specific surface area of 1622.83-1797.39 m^(2)/g and a better developed porous structure(the total pore volume Vtotal was 0.9434-1.0023 cm^(3)/g)than the SSB and SCB(specific surface area was 350.55-352.59 m^(2)/g,and Vtotal was 0.1907-0.1918 cm^(3)/g),indicating that modification promoted the formation of porous structure and thus improved the adsorption capacity of biochar.Adsorption experiments confirmed once again that the BaP removal rates of SSZ and SCZ(92.67%-96.13%)were much higher than that of unmodified biochar(3.34%-4.28%),and the BaP content in the sesame oil treated by SSZ and SCZ were far below the current EU maximum levels(2μg/kg).Therefore,the modified biochar from cellulose is a promising adsorbent for BaP removal.In future studies,the influences of bichar on the nutritional quality of edible oil should be taken into consideration so as to find an ideal active carbon substitute for BaP removal in edible oil.Qiaoli Yang Yanxia Sun Wenhui Sun Zhao Qin Huamin Liu Yuxiang Ma Xuede Wang 2021Grain & Oil Science and Technology2021,4,4:2

14Variation of δ^(13)C in karst soil in Yaji Karst Experiment Site, Guilin显示文摘This study deals with δ13C variation in karst soil system of Yaji Karst Experiment Site, Guilin, a typical region of humid subtropical karst formations. Samples of near ground air, plant tissue, soil and water (soil solution and karst spring) were respectively collected on site in different seasons during 1996-1999. Considerable variation of δ13C values are not only found with different carbon pools of soil organic carbon, soil air CO2 and soil water HCO3-, but also with the soil depths and with different seasons during a year. The δ13C values of CO2 both of near ground air and soil air are lower in July than those in April by 1‰-4‰ PDB. Our results indicate that the δ13C values of carbon in the water and air are essentially dependent on interface carbon interaction of air-plant-soil-rock-water governed by soilorganic carbon and soil CO2 in the system.PAN Genxing, HE Shiyi, CAO Jianhua, TAO Yuxiang & SUN YuhuaCollege of Resource and Environment Science, Nanjing Agricultural University, Nanjing 210095, China Karst Dyanmics Laboratory, Ministry of Land and Resources, Guilin 541004, China 2002Chinese Science Bulletin2002,47,6:1

17Environment Information-Based Channel Prediction Method Assisted by Graph Neural Network显示文摘Recently,whether the channel prediction can be achieved in diverse communication scenarios by directly utilizing the environment information gained lots of attention due to the environment impacting the propagation characteristics of the wireless channel.This paper presents an environment information-based channel prediction(EICP)method for connecting the environment with the channel assisted by the graph neural networks(GNN).Firstly,the effective scatterers(ESs)producing paths and the primary scatterers(PSs)generating single propagation paths are detected by building the scatterercentered communication environment graphs(SCCEGs),which can simultaneously preserve the structure information and highlight the pending scatterer.The GNN-based classification model is implemented to distinguish ESs and PSs from other scatterers.Secondly,large-scale parameters(LSP)and small-scale parameters(SSP)are predicted by employing the GNNs with multi-target architecture and the graphs of detected ESs and PSs.Simulation results show that the average normalized mean squared error(NMSE)of LSP and SSP predictions are 0.12 and 0.008,which outperforms the methods of linear data learning.Yutong Sun Jianhua Zhang Yuxiang Zhang Li Yu Qixing Wang Guangyi Liu 2022China Communications2022,19,11:1

19Key technology for construction of connection between steel pylonand concrete pile cap of middle pylon of Taizhou Bridge显示文摘Taizhou Bridge is a suspension bridge with three pylons and two 1 080 m main spans. The middle pylon is a steel frame with longitudinal herringbone shape and lateral gate shape. The connection between steel pylon and concrete pile cap is a key part to transfer the huge inner force from the pylon to the foundation. Its construction quality is a critical factor to the overall structural loading of the whole bridge; therefore the contact ratio between the bearing steel plate of pylon and concrete pile cap is required to be over 75 %. The inclined joint surface in two directions, longitudinally at 39/1 920 and laterally at 1/4, posted a challenge to the construction work. A procedure test was carried out to find an optimal construction method by comparison, and finally the post-injection method was selected as it can meet the requirement of concrete strength and contact ratio at the connection. The successful application of the post-injection method in Taizhou Bridge can provide an example and reference for similar projects in the future.Sun Yuxiang Zhang Hong Xiao Wenfu Huang Tao You Xinpeng 2012Engineering Sciences2012,10,3:1
