| 1 | Erianin,a novel dibenzyl compound in Dendrobium extract,inhibits lung cancer cell growth and migration via calcium/calmodulin-dependent ferroptosis显示文摘Ferroptosis,a novel form of programmed cell death,is characterized by iron-dependent lipid peroxidation and has been shown to be involved in multiple diseases,including cancer.Stimulating ferroptosis in cancer cells may be a potential strategy for cancer therapy.Therefore,ferroptosis-inducing drugs are attracting more attention for cancer treatment.Here,we showed that erianin,a natural product isolated from Dendrobium chrysotoxum Lindl,exerted its anticancer activity by inducing cell death and inhibiting cell migration in lung cancer cells.Subsequently,we demonstrated for the first time that erianin induced ferroptotic cell death in lung cancer cells,which was accompanied by ROS accumulation,lipid peroxidation,and GSH depletion.The ferroptosis inhibitors Fer-1 and Lip-1 but not Z-VAD-FMK,CQ,or necrostatin-1 rescued erianin-induced cell death,indicating that ferroptosis contributed to erianin-induced cell death.Furthermore,we demonstrated that Ca^(2+)/CaM signaling was a critical mediator of erianin-induced ferroptosis and that blockade of this signaling significantly rescued cell death induced by erianin treatment by suppressing ferroptosis.Taken together,our data suggest that the natural product erianin exerts its anticancer effects by inducing Ca^(2+)/CaMdependent ferroptosis and inhibiting cell migration,and erianin will hopefully serve as a prospective compound for lung cancer treatment. | Peng Chen Qibiao Wu Jiao Feng Lili Yan Yitian Sun Shuiping Liu Yu Xiang Mingming Zhang Ting Pan Xiaying Chen Ting Duan Lijuan Zhai Bingtao Zhai Wengang Wang Ruonan Zhang Bi Chen Xuemeng Han Yicong Li Liuxi Chen Ying Liu Xingxing Huang Ting Jin Wenzheng Zhang Hong Luo Xiaohui Chen Yongqiang Li Qiujie Li Guohua Li Qin Zhang Lvjia Zhuo Zuyi Yang Huifen Tang Tian Xie Xiaoping Ouyang Xinbing Sui | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 42 |
| 2 | Transcriptional activation and phosphorylation of OsCNGC9 confer enhanced chilling tolerance in rice显示文摘Low temperature is a major environmental factor that limits plant growth and productivity.Although transient elevation of cytoplasmic calcium has long been recognized as a critical signal for plant cold tolerance,the calcium channels responsible for this process have remained largely elusive.Here we report that OsCNGC9,a cyclic nucleotide-gated channel,positively regulates chilling tolerance by mediating cytoplasmic calcium elevation in rice(Oryza sativa).We showed that the loss-of-function mutant of OsCNGC9 is defective in cold-induced calcium influx and more sensitive to prolonged cold treatment,whereas OsCNGC9 overexpression confers enhanced cold tolerance.Mechanistically,we demonstrated that in response to chilling stress,OsSAPK8,a homolog of Arabidopsis thaliana OST1,phosphorylates and activates OsCNGC9 to trigger Ca2+influx.Moreover,we found that the transcription of OsCNGC9 is activated by a rice dehydration-responsive element-binding transcription factor,OsDREB1A.Taken together,our results suggest that OsCNGC9 enhances chilling tolerance in rice through regulating cold-induced calcium influx and cytoplasmic calcium elevation. | Jiachang Wang Yulong Ren Xi Liu Sheng Luo Xiao Zhang Xin Liu Qibing Lin Shanshan Zhu Hua Wan Yang Yang Yu Zhang Bin Lei Chunlei Zhou Tian Pan Yongfei Wang Mingming Wu Ruonan jing Yang Xu Meng Han Fuqing Wu Cailin Lei Xiuping Guo Zhijun Cheng Xiaoming Zheng Yihua Wang Zhigang Zhao Ling Jiang Xin Zhang Yong-Fei Wang Haiyang Wang Jianmin Wan | 2021 | Molecular Plant2021，14，2： | 10 |
| 3 | Curcumenol triggered ferroptosis in lung cancer cells via lncRNA H19/miR-19b-3p/FTH1 axis显示文摘Curcumenol,an effective ingredient of Wenyujin,has been reported that exerted its antitumor potential in a few cancer types.However,the effect and molecular mechanism of curcumenol in lung cancer are largely unknown.Here,we found that curcumenol induced cell death and suppressed cell proliferation in lung cancer cells.Next,we demonstrated that ferroptosis was the predominant method that contributed to curcumenol-induced cell death of lung cancer in vitro and vivo for the first time.Subsequently,using RNA sequencing,we found that the long non-coding RNA H19(lncRNA H19)was significantly downregulated in lung cancer cells treated with curcumenol,when compared to untreated controls.Overexpression of lncRNA H19 eliminated the anticancer effect of curcumenol,while lncRNA H19 knockdown promoted ferroptosis induced by curcumenol treatment.Mechanistically,we showed that lncRNA H19 functioned as a competing endogenous RNA to bind to miR-19b-3p,thereby enhanced the transcription activity of its endogenous target,ferritin heavy chain 1(FTH1),a marker of ferroptosis.In conclusion,our data show that the natural product curcumenol exerted its antitumor effects on lung cancer by triggering ferroptosis,and the lncRNA H19/miR-19b-3p/FTH1 axis plays an essential role in curcumenol-induced ferroptotic cell death.Therefore,our findings will hopefully provide a valuable drug for treating lung cancer patients. | Ruonan Zhang Ting Pan Yu Xiang Mingming Zhang Han Xie Zimao Liang Bi Chen Cong Xu Jing Wang Xingxing Huang Qianru Zhu Ziming Zhao Quan Gao Chengyong Wen Wencheng Liu Weirui Ma Jiao Feng Xueni Sun Ting Duan Elaine Lai-Han Leung Tian Xie Qibiao Wu Xinbing Sui | 2022 | Bioactive Materials2022，7，7： | 8 |
| 4 | Preparation, characterization, pharmacokinetics and anticancer effects of PEGylated β-elemene liposomes显示文摘Objective:This study aimed to develop a new polyethylene glycol(PEG)ylatedβ-elemene liposome(PEG-Lipo-β-E)and evaluate its characterization,pharmacokinetics,antitumor effects and safety in vitro and in vivo.Methods:The liposomes were prepared by ethanol injection and high-pressure micro-jet homogenization.Characterization of the liposomes was conducted,and drug content,entrapment efficiency(EE),in vitro release and stability were studied by ultra-fast liquid chromatography(UFLC)and a liquid surface method.Blood was drawn from rats to establish the pharmacokinetic parameters.The anticancer effect was evaluated in a KU-19-19 bladder cancer xenograft model.Histological analyses were performed to evaluate safety.Results:The PEG-Lipo-β-E showed good stability and was characterized as 83.31±0.181 nm in size,0.279±0.004 in polydispersity index(PDI),-21.4±1.06 mV in zeta potential,6.65±0.02 in pH,5.024±0.107 mg/mL inβ-elemene(β-E)content,and 95.53±1.712%in average EE.The Fourier transform infrared spectroscopy(FTIR)and differential scanning calorimetry(DSC)indicated the formation of PEG-Lipo-β-E.Compared to elemene injection,PEG-Lipo-β-E demonstrated a 1.75-fold decrease in clearance,a 1.62-fold increase in half-life,and a 1.76-fold increase in area under the concentration-time curves(AUCs)from 0 hour to 1.5 hours(P<0.05).PEG-Lipo-β-E also showed an enhanced anticancer effect in vivo.Histological analyses showed that there was no evidence of toxicity to the heart,kidney,liver,lung or spleen.Conclusions:The present study demonstrates PEG-Lipo-β-E as a new formulation with ease of preparation,high EE,good stability,improved bioavailability and antitumor effects. | Bingtao Zhai Qibiao Wu Wengang Wang Mingming Zhang Xuemeng Han Qiujie Li Peng Chen Xiaying Chen Xingxing Huang Guohua Li Qin Zhang Ruonan Zhang Yu Xiang Shuiping Liu Ting Duan Jianshu Lou Tian Xie Xinbing Sui | 2020 | Cancer Biology & Medicine2020，17，1： | 6 |
| 5 | An ATF24 peptide-functionalized β-elemene-nanostructured lipid carrier combined with cisplatin for bladder cancer treatment显示文摘Objective:In this study,we aimed to develop an amino-terminal fragment(ATF)peptide-targeted liposome carryingβ-elemene(ATF24-PEG-Lipo-β-E)for targeted delivery into urokinase plasminogen activator receptor-overexpressing bladder cancer cells combined with cisplatin(DDP)for bladder cancer treatment.Methods:The liposomes were prepared by ethanol injection and high-pressure microjet homogenization.The liposomes were characterized,and the drug content,entrapment efficiency,andin vitro release were studied.The targeting efficiency was investigated using confocal microscopy,ultra-fast liquid chromatography,and an orthotopic bladder cancer model.The effects of ATF24-PEG-Lipo-β-E combined with DDP on cell viability and proliferation were evaluated by a Cell Counting Kit-8(CCK-8)assay,a colony formation assay,and cell apoptosis and cell cycle analyses.The anticancer effects were evaluated in a KU-19-19 bladder cancer xenograft model.Results:ATF24-PEG-Lipo-β-E had small and uniform sizes(~79 nm),high drug loading capacity(~5.24 mg/mL),high entrapment efficiency(98.37±0.95%),and exhibited sustained drug release behavior.ATF24-PEG-Lipo-β-E had better targeting efficiency and higher cytotoxicity than polyethylene glycol(PEG)ylatedβ-elemene liposomes(PEG-Lipo-β-E).DDP,combined with ATF24-PEG-Lipo-β-E,exerted a synergistic effect on cellular apoptosis and cell arrest at the G2/M phase,and these effects were dependent on the caspase-dependent pathway and Cdc25C/Cdc2/cyclin B1 pathways.Furthermore,thein vivo antitumor activity showed that the targeted liposomes effectively inhibited the growth of tumors,using the combined strategy.Conclusions:The present study provided an effective strategy for the targeted delivery ofβ-elemene(β-E)to bladder cancer,and a combined strategy for bladder cancer treatment. | Bingtao Zhai Peng Chen Wengang Wang Shuiping Liu Jiao Feng Ting Duan Yu Xiang Ruonan Zhang Mingming Zhang Xuemeng Han Xiaying Chen Qiujie Li Guohua Li Ying Liu Xingxing Huang Wenzheng Zhang Ting Pan Lili Yan Ting Jin Tian Xie Xinbing Sui | 2020 | Cancer Biology & Medicine2020，17，3： | 5 |
| 6 | PCDH17 increases the sensitivity of colorectal cancer to 5-fluorouracil treatment by inducing apoptosis and autophagic cell death显示文摘5-Fluorouracil(5-FU)is known as a first-line chemotherapeutic agent against colorectal cancer(CRC),but drug resistance occurs frequently and significantly limits its clinical success.Our previous study showed that the protocadherin 17(PCDH17)gene was frequently methylated and functioned as a tumor suppressor in CRC.However,the relationship between PCDH17 and 5-FU resistance in CRC remains unclear.Here,we revealed that PCDH17 was more highly expressed in 5-FU-sensitive CRC tissues than in 5-FU-resistant CRC tissues,and high expression of PCDH17 was correlated with high BECN1 expression.Moreover,this expression profile contributed to superior prognosis and increased survival in CRC patients.Restoring PCDH17 expression augmented the 5-FU sensitivity of CRC in vitro and in vivo by promoting apoptosis and autophagic cell death.Furthermore,autophagy played a dominant role in PCDH17-induced cell death,as an autophagy inhibitor blocked cell death to a greater extent than the pancaspase inhibitor Z-VAD-FMK.PCDH17 inhibition by siRNA decreased the autophagy response and 5-FU sensitivity.Mechanistically,we showed that c-Jun NH2-terminal kinase(JNK)activation was a key determinant in PCDH17-induced autophagy.The compound SP600125,an inhibitor of JNK,suppressed autophagy and 5-FU-induced cell death in PCDH17-reexpressing CRC cells.Taken together,our findings suggest for the first time that PCDH17 increases the sensitivity of CRC to 5-FU treatment by inducing apoptosis and JNK-dependent autophagic cell death.PCDH17 may be a potential prognostic marker for predicting 5-FU sensitivity in CRC patients. | Shuiping Liu Haoming Lin Da Wang Qiang Li Hong Luo Guoxiong Li Xiaohui Chen Yongqiang Li Peng Chen Bingtao Zhai Wengang Wang Ruonan Zhang Bi Chen Mingming Zhang Xuemeng Han Qiujie Li Liuxi Chen Ying Liu Xiaying Chen Guohua Li Yu Xiang Ting Duan Jiao Feng Jianshu Lou Xingxing Huang Qin Zhang Ting Pan Lili Yan Ting Jin Wenzheng Zhang Lvjia Zhuo Yitian Sun Tian Xie Xinbing Sui | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 4 |
| 7 | Optimizing the operation of the Qingshitan Reservoir in the Lijiang River for multiple human interests and quasi-natural flow maintenance显示文摘For reservoir operation, maintaining a quasi-natural flow regime can benefit river ecosystems, but may sacrifice human interests. This study took the Qingshitan Reservoir in the Lijiang River as a case, and developed an optimization model to explore a trade-off solution between social-economic interests and nature flow maintenance on a monthly base. The objective function considered irrigation, cruise navigation and water supply aspects. An index of flow alteration degree was proposed to measure the difference between the regulated discharge and the natural flow. The index was then used as an additional constraint in the model besides the conventional constraints on reservoir safety. During model solving, different criteria were applied to the index, representing various degrees of alteration of the natural flow regime in the river. Through the model, a relationship between social-economic interests and flow alteration degree was established. Finally, a trade-off solution of the reservoir operation was defined that led to a favorable social-economic benefit at an acceptable alteration of the natural flow. | Qiuwen Chen Duan Chen Ruiguang Han Ruonan Li Jinfeng Ma Koen Blanckaert | 2012 | Journal of Environmental Sciences2012，24，11： | 2 |
| 8 | The Effect of CD3-Specific Monoclonal Antibody on Treating Experimental Autoimmune Myasthenia Gravis显示文摘CD3-specific monoclonal antibody was the first one used for clinical practice in field of transplantation. Recently,renewed interests have elicited in its capacity to prevent autoimmune diabetes by inducing immune tolerance. In this study, we tested whether this antibody can also be used to treat another kind of autoimmune disease myasthenia gravis (MG) and explored the possible mechanisms. MG is caused by an autoimmune damage mediated by antibody- and complement-mediated destruction of AChR at the neuromuscular junction. We found that administration of CD3-specific antibody (Fab)2 to an animal model with experimental autoimmune myasthenia gravis (EAMG) (B6 mice received 3 times of AChR/CFA immunization) could not significantly improve the clinical signs and clinical score. When the possible mechanisms were tested, we found that CD3 antibody treatment slightly down-regulated the T-cell response to AChR, modestly up-regulation the muscle strength. And no significant difference in the titers of IgG2b was found between CD3 antibody treated and control groups. These data indicated that CD3-specific antibody was not suitable for treating MG, an antibody- and complementmediated autoimmune disease, after this disease has been established. The role of CD3-specific antibody in treating this kind of disease remains to be determined. | Ruonan Xu~1 Jianan Wang~1 Guojiang Chen~1 Gencheng Han~1 Renxi Wang~1 Beifen Shen~1 Yan Li~(1,2) ~1Institute of Basic Medical Science,Academy of military Medical Science,Beijing 100850,China ~2Department of Molecular Immunology,Institute of Basic Medical Science,27 Taiping Road,Beijing 100850,China. | 2005 | Cellular & Molecular Immunology2005，2，6： | 2 |
| 9 | Catalytic degradation of lomefloxacin by photo-assisted persulfate activation on natural hematite:Performance and mechanism显示文摘The natural hematite(α-Fe_(2)O_(3)) is stable and abundant on the earth,as well as with strange electronic band structure and good visible light absorption properties.However,the composition and catalytic performance of natural hematite should be explored.In this study,the photo-assisted hematite nanoparticles activated persulfate(H-NPs/PS/vis)system was constructed.As detected,H-NPs had an irregular agglomerate structure with abundant internal pore and were mainly composed of Fe_(2)O_(3),SiO_(2) and TiO_(2).The system was applied to removing various antibiotic(i.e.,lomefloxacin,ciprofloxacin and enrofloxacin with initial concentration of 10 mg/L),achieving high degradation performance of 82.0%,81.2%and 82.2%after120,330 and 240 min,respectively.Moreover,H-NPs had excellent reusability with low metal leaching(Ti leaching percentage lower than 0.01%,Fe dissolution percentage was 0.48%)and stable structure.At last,a possible reaction mechanism of H-NPs/PS/vis system was proposed that lomefloxacin(LOM)was efficiently removed via the synergistic process of components contained in H-NPs with PS and light,involving the generation of·O_(2)^(-),·OH and SO_(4)^(·-).Above all,this paper provided a novel application scheme of natural hematite through in-depth and comprehensive experimental exploration. | Ruonan Guo Ying Chen Bingrui Liu Ying Han Jianfeng Gou Xiuwen Cheng | 2022 | Chinese Chemical Letters2022，33，8： | 1 |

| 11 | Personalized Learning Path Recommendations for Software Testing Courses Based on Knowledge Graphs显示文摘Software testing courses are characterized by strong practicality,comprehensiveness,and diversity.Due to the differences among students and the needs to design personalized solutions for their specific requirements,the design of the existing software testing courses fails to meet the demands for personalized learning.Knowledge graphs,with their rich semantics and good visualization effects,have a wide range of applications in the field of education.In response to the current problem of software testing courses which fails to meet the needs for personalized learning,this paper offers a learning path recommendation based on knowledge graphs to provide personalized learning paths for students. | Wei Zheng Ruonan Gu Xiaoxue Wu Lipeng Gao Han Li | 2023 | 计算机教育2023，，12： | 0 |
| 12 | 氮添加抑制温带草甸草原凋落物的长期分解显示文摘植物凋落物分解是陆地生态系统碳平衡和养分周转的关键,对持续的人为氮输入增加十分敏感。氮素增加影响凋落物分解的研究大多依赖于短期实验,这可能掩盖氮素增加对凋落物分解的真实影响。因此,长期实验对于全面评价凋落物分解对氮素增加的响应是非常必要的。本研究基于氮添加实验(0-50 g N m^(-2) yr^(-1)),对羊草(Leymus chinensis)凋落物分解进行了长达4年的研究,探讨了影响凋落物分解的非生物和生物因子。研究结果表明,随着氮添加速率的增加,凋落物分解速率呈持续下降趋势,为氮添加抑制凋落物分解提供了可靠的证据。氮添加条件下土壤环境(酸化和养分化学计量学)、微生物活性(微生物生物量和酶活性)、凋落物质量(残余木质素和养分含量)和植物群落(地上生产力和物种丰富度)的变化共同导致了凋落物分解速率的降低。在分解过程中,凋落物质量的变化,包括木质素的积累和养分的残留,主要受土壤环境和微生物活性的影响。该研究有助于阐明不同氮添加速率对凋落物分解的长期影响,并有助于理解生态系统氮素增加与碳循环之间的关系及相关机理。 | Pei Zheng Ruonan Zhao Liangchao Jiang Guojiao Yang Yinliu Wang Ruzhen Wang Xingguo Han Qiushi Ning | 2023 | Journal of Plant Ecology2023，16，3： | 0 |
| 13 | Suppression of transmembrane sodium currents on the freshly isolated hippocampal neuron cell with continuous infrared light显示文摘Physiotherapeutic effects of infrared lasers have been proved in clinic.These infrared-based regulations of the bioelectrical activities can roughly be classied into enhancement and suppression of action potential(AP),which are described by sodium(Na)and potassium(K)transmembrane current equations,named as Hodgkin and Huxley(HH)-model.The enhancement effect is able to evoke or strengthen the AP when infrared light is applied.Its corresponding mechanism is commonly ascribed to the changes of the cell membrane capacitance,which is transiently increased in response to the infrared radiation.The distinctive feature of the suppression effect is to inhibit or reduce the AP by the designed protocols of infrared radiation.However,its mechanism presents more complexity than that in enhancement cases.HH-model describes how the Na current determines the initial phase of AP.So,the enhancement and suppression of AP can be also ascribed to the regulations of the corresponding Na currents.Here,a continuous infrared light at the wavelength of 980 nm(CIS-980)was employed to stimulate a freshly isolated hippocampal neuron in vitro and a suppression effect on the Na currents of the neuron cell was observed.Both Na and K currents,which are named as whole cell currents,were simultaneously recorded with the cell membrane capacitance current by using a patch clamp combined with infrared irradiation.The results demonstrated that the CIS-980 was able to reversibly increase the capacitance currents,completely suppressed Na currents,but little changed K currents,which forms the steady outward whole cell currents and plays a major role on the AP repolarization.A conrmation experiment was designed and carried out by synchronizing tens of milliseconds of infrared stimulation on the same kinds of hippocampal neuron cells.After the blocked K channel,a reduction of Na current amplitude was still recorded.This proved that infrared suppression of Na current was irrelevant to K channel.A membrane capacitance mediation process was preliminarily proposed to explain the Na channel suppression process. | Fanyi Kong Xinyu Li Ruonan Jiao Kun Liu Xue Han Changkai Sun Changsen Sun | 2023 | Journal of Innovative Optical Health Sciences2023，16，2： | 0 |
| 14 | Synergy of I-Cl co-occupation on halogen-rich argyrodites and resultant dual-layer interface for advanced all-solid-state Li metal batteries显示文摘The(electro)chemical stability and Li dendrite suppression capability of sulfide solid electrolytes(SEs)need further improvement for developing all-solid-state Li batteries(ASSLBs).Here,we report advanced halogen-rich argyrodites via I and Cl co-occupation on the crystal lattice.Notably,a proper I content forms a single phase,whereas an excessive I causes precipitation of two argyrodite phases like a superlattice structure.The resultant synergistic effect of the optimized composition allows to gain high ionic conductivities at room temperature and-20℃,and enhances the(electro)chemical stability against Li and Li dendrite suppression capability.The Li|argyrodite interface is very sensitive to the ratio of I and Cl.A LiCl-and LiI-rich double-layer interface is observed from the cell using the SE with optimized composition,whereas too high I content forms only a single interface layer with a mixture of Lil and LiCl.This double-layer interface is found to effectively mitigate the Li/SE reaction.The proper designed argyrodite enables ASSLBs to achieve good electrochemical properties at a broad temperature range regardless of the electrode materials.This co-occupation strategy provides a novel exploration for advanced halogen-rich argyrodite system. | Han Yan Ruifeng Song Ruonan Xu Shulin Li Qiaoquan Lin Xinlin Yan Zhenyu Wang Chuang Yu Long Zhang | 2023 | Journal of Energy Chemistry2023，，11： | 0 |
| 15 | Diagnosis and Treatment Guidelines for Mesenchymal Stem Cell Therapy for Coronavirus Disease 2019(Beijing,2021)显示文摘The coronavirus disease 2019(COVID-19)can be caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection,and has led to millions of deaths among more than 100 million infected people around the world according to the declaration from World Health Organization.Dysregulated immune response of both the innate and adaptive immune systems is subsistent on COVID-19 patients,of which the degree are associated with disease severity,lung damage and long term functional disability.Current treatment options have included antiretroviral drugs,anti-inflammatory factors,antibodies,immune checkpoint inhibitors,and convalescent plasma therapy.More recently,mesenchymal stem cell(MSC)therapy has been explored for the management and control of COVID-19,particularly with the aim of preventing or at least mitigating respiratory co-morbidities.Though the safety and efficacy of stem cell therapy have been validated in multiple phase I–III clinical trials,to date,no standardized stem cell preparation,administration dosage or interval,product QA/QC testing,storage,transportation,or disposal protocols have been established.The present paper proposes a systematic methodology that addresses all the foregoing process steps and evaluation criteria for the efficacious and safe administration of MSCs in the treatment of patients infected with COVID-19. | Ruonan Xu Lei Shi Wei-Fen Xie Zhe Xu Fan-Ping Meng Jun-Liang Fu Xin Yuan Lei Huang Ming Shi Yonggang Li Yuanyuan Li Chen Yao Yu Zhang Zhongmin Liu Chenyan Gao Zhaohui Wu Shufang Meng Weidong Han Charlie Xiang Gui-Qiang Wang Taisheng Li Xiaoying Wang Yunxia Sun Zunyou Wu Wenhong Zhang Chunhua Zhao Yu Hu Tao Cheng Yuquan Wei Qi Zhou Fu-Sheng Wang | 2021 | Infectious Diseases & Immunity2021，1，2： | 0 |
| 16 | Pd cluster decorated free standing flexible cathode for high performance Li-oxygen batteries显示文摘As a promising candidate for the next generation energy storage system,rechargeable lithium-oxygen batteries(LOBs)still face substantial challenges caused by insulating discharge products that preclude their practical application.Exploring highly efficient cathode catalysts capable of facilitating formation/decomposition of discharge products is considered as an essential approach towards high performance LOBs.Herein,Pd decorated Te nanowires(Pd@Te NWs)were synthesized as advanced catalyst in LOBs to maximize Pd utilization and achieve synergistic effect,in which Pd clusters were uniformly grown on Te substrate though regulating the Pd:Te ratio.Meanwhile,Pd@Te nanowires assembled into an interpenetrating network-like structure by vacuum filtration and employed as flexible cathode,enabling LOBs achieved an ultralong 190 cycles stability and a superior specific capacity of 3.35 mAh·cm^(-2).Experimental studies and density functional theory(DFT)calculations reveal the excellent catalytic ability of Pd@Te and synergistic catalytic mechanism of Pd and Te,in which uniform electron distribution,extensive electron exchange,and large adsorption distance between Pd cluster and discharge products promote homogeneous adsorption/desorption of discharge products,while the high adsorption energy of Te substrate for Li species reduces the initial dynamical energy barrier during discharging process.The current work provides viable strategy to design composite catalysts for flexible cathode of LOBs with synergistic catalytic effects. | Liang Guo Guoliang Zhang Ruonan Yang Dongmei Zhang Xiuqi Zhang Han Yu Xia Li Feng Dang | 2024 | Nano Research2024，17，4： | 0 |
| 17 | Functional Identification of the Stable Transfection C5aR Cell Line Molt-4显示文摘The complement C5 anaphylatoxin receptor is a member of the seven transmembrane-spanning G protein-coupled receptor superfamily that signals through Gαi and Gα16.C5aR is mostly expressed on neutrophils,macrophages and endothelial cells.C5a and C5aR interaction plays an important role in numerous biological effects such as in vivo cytokine storm which results in inflammatory damage.Considering the limitation of collection of human peripheral blood neutrophils and their short half life,the stably transfected cell line for studying the biological effects of C5aR is needed.In this study,we transfected C5aR gene into Molt-4 cell line and examined the function of ectopic C5aR.Our results showed stable expression of the C5aR in Molt-4 cell line and their interaction with human C5a induced ERK1/2 phosphorylation,Ca ++ influx.This stable transfected cell line may provide a useful tool for studying signal pathways related to C5a and C5aR interplay and antibody development specific for C5aR. | Chunmei Zhang Ruonan Xu Jianan Wang Gencheng Han Guojiang Chen Renxi Wang Huawei Wei Beifen Shen Yuanfang Ma Yan Li | 2007 | Cellular & Molecular Immunology2007，4，6： | 0 |
| 18 | Federated selective aggregation for on-device knowledge amalgamation显示文摘In the current work,we explored a new knowledge amalgama-tion problem,termed Federated Selective Aggregation for on-device knowledge amalgamation(FedSA).FedSA aims to train an on-device student model for a new task with the help of several decentralized teachers whose pre-training tasks and data are different and agnos-tic.The motivation to investigate such a problem setup stems from a recent dilemma of model sharing.Due to privacy,security or in-tellectual property issues,the pre-trained models are,however,not able to be shared,and the resources of devices are usually limited.The proposed FedSA offers a solution to this dilemma and makes it one step further,again,the method can be employed on low-power and resource-limited devices.To this end,a dedicated strategy was proposed to handle the knowledge amalgamation.Specifically,the student-training process in the current work was driven by a novel saliency-based approach which adaptively selects teachers as the par-ticipants and integrated their representative capabilities into the stu-dent.To evaluate the effectiveness of FedSA,experiments on both single-task and multi-task settings were conducted.The experimental results demonstrate that FedSA could effectively amalgamate knowl-edge from decentralized models and achieve competitive performance to centralized baselines. | Donglin Xie Ruonan Yu Gongfan Fang Jiaqi Han Jie Song Zunlei Feng Li Sun Mingli Song | 2023 | Chip2023，2，3： | 0 |

| 20 | iBP-seq:An efficient and low-cost multiplex targeted genotyping and epigenotyping system显示文摘Inter-and intra-specific variations in phenotype are common and can be associated with genomic mutations as well as epigenomic variation.Profiling both genomic and epigenomic variants is at the core of dissecting phenotypic variation.However,an efficient targeted genotyping and epigenotyping system is lacking.We describe a new multiplex targeted genotyping and epigenotyping system called improved bulked-PCR sequencing(iBP-seq).We employed iBP-seq for the detection of genotypes and methylation levels of dozens of target regions in mixed DNA samples.iBP-seq can be adapted for the construction of linkage maps,fine mapping of quantitative-trait loci,and detection of genome editing mutations at a cost as low as$0.016 per site per sample.We developed an automated bioinformatics pipeline,including primer design,a series of bioinformatic analyses for genotyping and epigenotyping,and visualization of results.iBP-seq and its bioinformatics pipeline,available at http://zeasystemsbio.hzau.edu.cn/tools/ibp/,can be adapted to a wide variety of species. | Juan Li Rui Han Ruonan Li Qiang Xu Mingzhu Li Yue Tang Jixiang Li Xi Wang Zhao Li Qing Li Zaiwen Feng Lin Li | 2023 | The Crop Journal2023，11，5： | 0 |
