| 1 | Characterization of a Mg_(95.5)Zn_(1.5)Y_(3)alloy both containing W phase and LPSO phase with or without heat treatment显示文摘The influence of solid solution treatment on the microstructure and corrosion resistance of as-cast Mg_(95.5)Zn_(1.5)Y_(3) alloy is characterized.The microstructure of the as-cast Mg_(95.5)Zn_(1.5)Y_(3) alloy mainly consisted ofα-Mg,W(Mg_(3)Zn_(3)Y_(2))phase,and the long period stacking ordered(LPSO)(Mg_(12)ZnY)phase.After solid solution treatment,most of the W phase disappears gradually with increasing solution treatment time,with only a small amount of W phase distributed as particle.The LPSO phase slightly dissolved into substrate,and its morphology transitions from blocky shape to rod shape.Solid solution treatment of Mg_(95.5)Zn_(1.5)Y_(3) exhibits excellent corrosion resistance,because the Y and Zn atoms became enriched in the matrix and the changed morphologies of the LPSO and W phases were modified through heat treatment.The alloy created with solid solution treatment at 520 ℃ for 10 hours exhibits corrosion potential of−1.419 V,suggesting a significant improvement in corrosion performance. | Li Zhumin Wan Diqing Huang Yi Ye Shuting Hu Yinglin | 2017 | Journal of Magnesium and Alloys2017，5，2： | 8 |
| 2 | Isogeometric topology optimization based on energy penalization for symmetric structure显示文摘We present an energy penalization method for isogeometric topology optimization using moving morphable components(ITO–MMC),propose an ITO–MMC with an additional bilateral or periodic symmetric constraint for symmetric structures,and then extend the proposed energy penalization method to an ITO–MMC with a symmetric constraint.The energy penalization method can solve the problems of numerical instability and convergence for the ITO–MMC and the ITO–MMC subjected to the structural symmetric constraint with asymmetric loads.Topology optimization problems of asymmetric,bilateral symmetric,and periodic symmetric structures are discussed to validate the effectiveness of the proposed energy penalization approach.Compared with the conventional ITO–MMC,the energy penalization method for the ITO–MMC can improve the convergence rate from 18.6%to 44.5%for the optimization of the asymmetric structure.For the ITO–MMC under a bilateral symmetric constraint,the proposed method can reduce the objective value by 5.6%and obtain a final optimized topology that has a clear boundary with decreased iterations.For the ITO–MMC under a periodic symmetric constraint,the proposed energy penalization method can dramatically reduce the number of iterations and obtain a speedup of more than 2. | Xianda XIE Shuting WANG Ming YE Zhaohui XIA Wei ZHAO Ning JIANG Manman XU | 2020 | Frontiers of Mechanical Engineering2020，15，1： | 3 |
| 3 | Genomic evidence of lung carcinogenesis associated with coal smoke in Xuanwei area, China显示文摘Xuanwei area, in southwestern China,harbors the highest female lung cancer rate in the country(Supplementary Table 1) [1]. Epidemiological studies have shown that lung cancer incidence in Xuanwei area is associated with the use of different types of local coal for household cooking and heating [2]. The genomic landscape of Xuanwei female adenocarcinoma(XWFA), the most distinctive feature of lung cancer in Xuanwei, has yet to be elucidated systematically. Here,we provide the fundamental resource of genomic datasets for further exploration of XWFA molecular mechanisms and development of targetable therapy. | Honglei Zhang Chao Liu Li Li Xu Feng Qing Wang Jihua Li Shaobin Xu Shuting Wang Qianlu Yang Zhenghai Shen Jinhua Su Xiaosan Su Ruifen Sun Xuhong Zhou Junliang Wang Yongchun Zhou Baowei Jiao Wanbao Ding Xianbao Cao Yue Wang Yunchao Huang Lianhua Ye | 2021 | National Science Review2021，8，12： | 2 |
| 4 | Exosomes secreted from cardiomyocytes suppress the sensitivity of tumor ferroptosis in ischemic heart failure显示文摘Heart failure(HF)patients in general have a higher risk of developing cancer.Several animal studies have indicated that cardiac remodeling and HF remarkably accelerate tumor progression,highlighting a cause-and-effect relationship between these two disease entities.Targeting ferroptosis,a prevailing form of non-apoptotic cell death,has been considered a promising therapeutic strategy for human cancers.Exosomes critically contribute to proximal and distant organ-organ communications and play crucial roles in regulating diseases in a paracrine manner.However,whether exosomes control the sensitivity of cancer to ferroptosis via regulating the cardiomyocyte-tumor cell crosstalk in ischemic HF has not yet been explored.Here,we demonstrate that myocardial infarction(MI)decreased the sensitivity of cancer cells to the canonical ferroptosis activator erastin or imidazole ketone erastin in a mouse model of xenograft tumor.Post-MI plasma exosomes potently blunted the sensitivity of tumor cells to ferroptosis inducers both in vitro in mouse Lewis lung carcinoma cell line LLC and osteosarcoma cell line K7M2 and in vivo with xenograft tumorigenesis model.The expression of miR-22-3p in cardiomyocytes and plasma-exosomes was significantly upregulated in the failing hearts of mice with chronic MI and of HF patients as well.Incubation of tumor cells with the exosomes isolated from post-MI mouse plasma or overexpression of miR-22-3p alone abrogated erastin-induced ferroptotic cell death in vitro.Cardiomyocyte-enriched miR-22-3p was packaged in exosomes and transferred into tumor cells.Inhibition of cardiomyocyte-specific miR-22-3p by AAV9 sponge increased the sensitivity of cancer cells to ferroptosis.ACSL4,a pro-ferroptotic gene,was experimentally established as a target of miR-22-3p in tumor cells.Taken together,our findings uncovered for the first time that MI suppresses erastin-induced ferroptosis through releasing miR-22-3p-enriched exosomes derived from cardiomyocytes.Therefore,targeting exosome-mediated cardiomyocyte/tumor pathological communication may offer a novel approach for the ferroptosis-based antitumor therapy. | Ye Yuan Zhongting Mei Zhezhe Qu Guanghui Li Shuting Yu Yingqi Liu Kuiwu Liu Zhihua Shen Jiaying Pu Yanquan Wang Changhao Wang Zhiyong Sun Qian Liu Xiaochen Pang Ao Wang Zijing Ren Tong Wang Ying Liu Jinhuan Hong Jiajie Xie Xin Li Zhonghua Wang Weijie Du Baofeng Yang | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 2 |
| 5 | Low-bandgap conjugated polymers based on benzodipyrrolidone with reliable unipolar electron mobility exceeding 1 cm^(2) V^(-1)s^(-1)显示文摘The employment of an intrinsic quinoidal building block,benzodipyrrolidone(BDP),on constructing conjugated polymers(PBDP-2F and PBDP-2CN)with high electron mobility and unipolar transport characteristic in polyethylenimine ethoxylated(PEIE)modified organic field-effect transistors(OFETs)is reported.The intrinsic quinoidal characteristic and excellent coplanarity of BDP can lower the lowest unoccupied molecular orbital(LUMO)levels and improve ordered interchain packing of the resulting polymers in solid states,which are favorable for electron-injection and transport.By using PEIE as the interlayer to block the hole injection,unipolar n-type transport characteristics with high electron mobility of 0.58 and 1.01 cm^(2) V^(-1)s^(-1)were achieved by the OFETs based on PBDP-2F and PBDP-2CN,respectively.More importantly,the extracted mobilities are highly reliable with the reliability factor of above 80%.To the best of our knowledge,PBDP-2CN is the very first quinoid-based conjugated polymer with reliable electron mobility exceeding 1 cm^(2) V^(-1)s^(-1).This work represents a significant step in exploring intrinsic quinoidal CPs for application in n-channel OFETs and logic complementary circuits. | Mingqun Yang Tian Du Xuxia Zhao Xuelong Huang Langheng Pan Shuting Pang Haoran Tang Zhongxiang Peng Long Ye Yunfeng Deng Mingliang Sun Chunhui Duan Fei Huang Yong Cao | 2021 | Science China Chemistry2021，64，7： | 1 |

| 7 | stAPAminer:Mining Spatial Patterns of Alternative Polyadenylation for Spatially Resolved Transcriptomic Studies显示文摘Alternative polyadenylation(APA)contributes to transcriptome complexity and gene expression regulation and has been implicated in various cellular processes and diseases.Singlecell RNA sequencing(scRNA-seq)has enabled the profiling of APA at the single-cell level;however,the spatial information of cells is not preserved in scRNA-seq.Alternatively,spatial transcriptomics(ST)technologies provide opportunities to decipher the spatial context of the transcriptomic landscape.Pioneering studies have revealed potential spatially variable genes and/or splice isoforms;however,the pattern of APA usage in spatial contexts remains unappreciated.In this study,we developed a toolkit called stAPAminer for mining spatial patterns of APA from spatially barcoded ST data.APA sites were identified and quantified from the ST data.In particular,an imputation model based on the k-nearest neighbors algorithm was designed to recover APA signals,and then APA genes with spatial patterns of APA usage variation were identified.By analyzing wellestablished ST data of the mouse olfactory bulb(MOB),we presented a detailed view of spatial APA usage across morphological layers of the MOB.We compiled a comprehensive list of genes with spatial APA dynamics and obtained several major spatial expression patterns that represent spatial APA dynamics in different morphological layers.By extending this analysis to two additional replicates of the MOB ST data,we observed that the spatial APA patterns of several genes were reproducible among replicates.stAPAminer employs the power of ST to explore the transcriptional atlas of spatial APA patterns with spatial resolution.This toolkit is available at http://gffzz188fe103f8f1460asp0qopkou59pf6cxb.ffgz.tsg.suse.edu.cn/BMILAB/stAPAminer and http://gffzz77e3413bc06540edsp0qopkou59pf6cxb.ffgz.tsg.suse.edu.cn/biocode/tools/BT007320. | Guoli Ji Qi Tang Sheng Zhu Junyi Zhu Pengchao Ye Shuting Xia Xiaohui Wu | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 1 |

| 11 | Evidence of bisphosphonate-conjugated sitafloxacin eradication of established methicillin-resistant S.aureus infection with osseointegration in murine models of implant-associated osteomyelitis显示文摘Eradication of MRSA osteomyelitis requires elimination of distinct biofilms.To overcome this,we developed bisphosphonateconjugated sitafloxacin(BCS,BV600072)and hydroxybisphosphonate-conjugate sitafloxacin(HBCS,BV63072),which achieve“target-and-release”drug delivery proximal to the bone infection and have prophylactic efficacy against MRSA static biofilm in vitro and in vivo.Here we evaluated their therapeutic efficacy in a murine 1-stage exchange femoral plate model with bioluminescent MRSA(USA300LAC::lux).Osteomyelitis was confirmed by CFU on the explants and longitudinal bioluminescent imaging(BLI)after debridement and implant exchange surgery on day 7,and mice were randomized into seven groups:1)Baseline(harvested at day7,no treatment);2)HPBP(bisphosphonate control for BCS)+vancomycin;3)HPHBP(hydroxybisphosphonate control for HBCS)+vancomycin;4)vancomycin;5)sitafloxacin;6)BCS+vancomycin;and 7)HBCS+vancomycin.BLI confirmed infection persisted in all groups except for mice treated with BCS or HBCS+vancomycin.Radiology revealed catastrophic femur fractures in all groups except mice treated with BCS or HBCS+vancomycin,which also displayed decreases in peri-implant bone loss,osteoclast numbers,and biofilm.To confirm this,we assessed the efficacy of vancomycin,sitafloxacin,and HBCS monotherapy in a transtibial implant model.The results showed complete lack of vancomycin efficacy while all mice treated with HBCS had evidence of infection control,and some had evidence of osseous integrated septic implants,suggestive of biofilm eradication.Taken together these studies demonstrate that HBCS adjuvant with standard of care debridement and vancomycin therapy has the potential to eradicate MRSA osteomyelitis. | Youliang Ren Jason Weeks Thomas Xue Joshua Rainbolt Karen L.de Mesy Bentley Ye Shu Yuting Liu Elysia Masters Philip Cherian Charles E.McKenna Jeffrey Neighbors Frank H.Ebetino Edward M.Schwarz Shuting Sun Chao Xie | 2023 | Bone Research2023，11，4： | 0 |
| 12 | Revisiting the ionic diffusion mechanism in Li_(3)PS_(4) via the joint usage of geometrical analysis and bond valence method显示文摘Inorganic solid electrolytes have obvious advantages on safety and electrochemical stability compared to organic liquid electrolytes,but the advance on high ionic conductivity of typical electrolytes is still undergoing.Although the first-principles calculation in the ion migration simulation is an important strategy to develop high-performance solid electrolyte,the process is very time-consuming.Here,we propose an effective method by combining the geometrical analysis and bond valance sum calculation to obtain an approximate minimum energy path preliminarily,in parallel to pave the way for the interoperability of low-precision and high-precision ion transport calculation.Taking a promising electrolyte Li_(3)PS_(4) as an example,we revisit its Li-ionic transport behavior.Our calculated Li-ion pathways and the activation energies(the corresponding values:1.09 eV vs.0.88 eV vs.0.86 eV)in γ-,β- and α-Li_(3)PS_(4) are consistent with the ones obtained from the first-principles calculations.The variations of the position of P-ions lead the rearrangement of the host PS_(4) tetrahedron,affecting the diffusion positions of Li-ions and further enabling high Li^(+) conductivity in β-Li_(3)PS_(4). | Li Pan Liwen Zhang Anjiang Ye Shuting Chi Zheyi Zou Bing He Lanli Chen Qian Zhao Da Wang Siqi Shi | 2019 | Journal of Materiomics2019，5，4： | 0 |
