| 1 | The Influence of Extractable Organic Matter on Pore Development in the Late Triassic Chang 7 Lacustrine Shales, Yanchang Formation, Ordos Basin, China显示文摘To investigate the influence of extractable organic matter(EOM) on pore evolution of lacustrine shales, Soxhlet extraction, using dichloromethane, was performed on a series of Chang 7 shale samples(Ordos Basin, China) with vitrinite reflectance of 0.64% to 1.34%. Low-pressure gas adsorption experiments were conducted on the samples before and after extraction. The pore structure parameters were calculated from the gas adsorption data. The results show complex changes to the pore volumes and surface areas after extraction. The pore development of both the initial and extracted samples is strongly controlled by total organic carbon(TOC) content. Micropores developed mainly in organic matter(OM), while mesopores and macropores predominantly developed in fractions other than OM. The influence of EOM on micropores is stronger than on mesopores and macropores. Organic solvents with a higher boiling point should be used to explore the effect of EOM on pore structure in the future. | HAN Hui LIU Pengwei DING Zhengang SHI Pitong JIA Jianchao ZHANG Wei LIU Yan CHEN Shijia LU Jungang Chen Kang PENG Xudong WANG Zhiyong XIAO Shuqi GAO Yuans | 2018 | Acta Geologica Sinica(English Edition)2018，92，4： | 8 |
| 2 | Host metabolism dysregulation and cell tropism identification in human airway and alveolar organoids upon SARS-CoV-2 infection显示文摘The coronavirus disease 2019(COVID-19)pandemic is caused by infection with the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),which is spread primary via respiratory droplets and infects the lungs.Currently widely used cell lines and animals are unable to accurately mimic human physiological conditions because of the abnormal status of cell lines(transformed or cancer cells)and species differences between animals and humans.Organoids are stem cell-derived selforganized three-dimensional culture in vitro and model the physiological conditions of natural organs.Here we showed that SARS-CoV-2 infected and extensively replicated in human embryonic stem cells(hESCs)-derived lung organoids,including airway and alveolar organoids which covered the complete infection and spread route for SARS-CoV-2 within lungs.The infected ceils were ciliated,club,and alveolar type 2(AT2)cells,which were sequentially located from the proximal to the distal airway and terminal alveoli,respectively.Additionally,RNA-seq revealed early cell response to virus infection including an unexpected downregulation of the metabolic processes,especially lipid metabolism,in addition to the well-known upregulation of immune response.Further,Remdesivir and a human neutralizing antibody potently inhibited SARS-CoV-2 replication in lung organoids.Therefore,human lung organoids can serve as a pathophysiological model to investigate the underlying mechanism of SARS-CoV-2 infection and to discover and test therapeutic drugs for COVID-19. | Rongjuan Pei Jianqi Feng Yecheng Zhang Hao Sun Lian Li Xuejie Yang Jiangping He Shuqi Xiao Jin Xiong Ying Lin Kun Wen Hongwei Zhou Jiekai Chen Zhili Rong Xinwen Chen | 2021 | Protein & Cell2021，12，9： | 7 |
| 3 | Optical Micro/Nano Fibers Enabled Smart Textiles for Human-Machine Interface显示文摘Wearable human-machine interface(HMI)is an advanced technology that has a wide range of applications from robotics to augmented/virtual reality(AR/VR).In this study,an optically driven wearable human-interactive smart textile is proposed by integrating a polydimethylsiloxane(PDMS)patch embedded with optical micro/nanofibers(MNF)array with a piece of textiles.Enabled by the highly sensitive pressure dependent bending loss of MNF,the smart textile shows high sensitivity(65.5 kPa^(−1))and fast response(25 ms)for touch sensing.Benefiting from the warp and weft structure of the textile,the optical smart textile can feel slight finger slip along the MNF.Furthermore,machine learning is utilized to classify the touch manners,achieving a recognition accuracy as high as 98.1%.As a proof-of-concept,a remote-control robotic hand and a smart interactive doll are demonstrated based on the optical smart textile.This optical smart textile represents an ideal HMI for AR/VR and robotics applications. | Shuqi Ma Xiaoyu Wang Pan Li Ni Yao Jianliang Xiao Haitao Liu Zhang Zhang Longteng Yu Guangming Tao Xiong Li Limin Tong Lei Zhang | 2022 | Advanced Fiber Materials2022，4，5： | 5 |
| 4 | Single optical microfiber enabled tactile sensor for simultaneous temperature and pressure measurement显示文摘The ability to sense heat and touch is essential for healthcare,robotics,and human–machine interfaces.By taking advantage of the engineerable waveguiding properties,we design and fabricate a flexible optical microfiber sensor for simultaneous temperature and pressure measurement based on theoretical calculation.The sensor exhibits a high temperature sensitivity of 1.2 nm/℃ by measuring the shift of a high-order mode cutoff wavelength in the short-wavelength range.In the case of pressure sensing,the sensor shows a sensitivity of 4.5%per kilopascal with a fast temporal frequency response of 1000 Hz owing to the strong evanescent wave guided outside the microfiber.The cross talk is negligible because the temperature and pressure signals are measured at different wavelengths based on different mechanisms.The properties of fast temporal response,high temperature,and pressure sensitivity enable the sensor for real-time skin temperature and wrist pulse measurements,which is critical to the accurate analysis of pulse waveforms.We believe the sensor will have great potential in wearable optical devices ranging from healthcare to humanoid robots. | NI YAO XIAOYU WANG SHUQI MA XINGDA SONG SHAN WANG ZHANGXING SHI JING PAN SHIPENG WANG JIANLIANG XIAO HAITAO LIU LONGTENG YU YAO TANG ZHANG ZHANG XIONG LI WEI FANG LEI ZHANG LIMIN TONG | 2022 | Photonics Research2022，10，9： | 2 |
| 5 | Effect of DC electric field on moisture migration characteristics in oil-pressboard显示文摘The moisture content has a great influence on the electric insulation strength of oil-pressboard.Therefore,it is very important to assess the moisture content in power transformers.There is lack of research about the effect of DC electric field on moisture migration.Here,the authors analyse the moisture migration characteristics of oil-press-board under DC electric field.The DC electric field has a greater influence on the moisture content in the oil.Compared with no DC electric field,the moisture content in oil is reduced by 22.91 mg/L at 50℃,while it is reduced by 17.63 mg/L at 70℃.Under the same moisture content in the oil,the moisture content in the pressboard which affected by the DC electric field is higher than the Oommen curve,the maximum dif-ference is 0.88%at 50℃,and 0.05%at 70℃.This result can provide a reference for the revision of existing moisture assessment methods. | Qing Yuan Bo Qi Jianshe Zhao Chunjia Gao Xiao Yang Shuqi Zhang Chengrong Li | 2021 | High Voltage2021，6，4： | 1 |

| 8 | Expression of heat-resistant β-glucosidase in Escherichia coli and its application in the production of gardenia blue显示文摘Gardenia blue is a natural blue pigment that is environmentally friendly,non-toxic,and stable.The hydrolysis of geniposide,catalyzed byβ-glucosidase,is a critical step in the production process of gardenia blue.However,β-glucosidase is not resistant to high temperatures,limiting the production of gardenia blue.In this study,we investigated the effectiveness of a heat-resistant glucosidase obtained from Thermotoga maritima in the production of gardenia blue.The enzyme exhibited a maximum activity of 10.60 U/mL at 90℃.Single-factor and orthogonal analyses showed that exogenously expressed heat-resistant glucosidase reacted with 470.3μg/mL geniposide and 13.5μg/mL glycine at 94.2℃,producing a maximum yield of 26.2857μg/mL of gardenia blue after 156.6 min.When applied to the dyeing of denim,gardenia blue produced by this method yielded excellent results;the best color-fastness was achieved when an iron ion mordant was used.This study revealed the feasibility and application potential of microbial production of gardenia blue. | Wenxi Li Jielin Li Ying Xu Yan Huang Shuqi Xu Zirui Ou Xiaoli Long Xinyu Li Xinyu Liu Zening Xiao Jiaqi Huang Weizhao Chen | 2021 | Synthetic and Systems Biotechnology2021，6，3： | 1 |
| 9 | Robust hydrogel sensors for unsupervised learning enabled sign-to-verbal translation显示文摘Highly stretchable and robust strain sensors are rapidly emerging as promising candidates for a diverse of wearable electronics.The main challenge for the practical application of wearable electronics is the energy consumption and device aging.Energy consumption mainly depends on the conductivity of the sensor,and it is a key factor in determining device aging.Here,we design a liq-uid metal(LM)-embedded hydrogel as a sensing material to overcome the bar-rier of energy consumption and device aging of wearable electronics.The sensing material simultaneously exhibits high conductivity(up to 22 S m�1),low elastic modulus(23 kPa),and ultrahigh stretchability(1500%)with excel-lent robustness(consistent performance against 12000 mechanical cycling).A motion monitoring system is composed of intrinsically soft LM-embedded hydrogel as sensing material,a microcontroller,signal-processing circuits,Bluetooth transceiver,and self-organizing map developed software for the visu-alization of multi-dimensional data.This system integrating multiple functions including signal conditioning,processing,and wireless transmission achieves monitor hand gesture as well as sign-to-verbal translation.This approach provides an ideal strategy for deaf-mute communicating with normal people and broadens the application of wearable electronics. | Hude Ma Haiyang Qin Xiao Xiao Na Liu Shaolei Wang Junye Li Sophia Shen Shuqi Dai Mengmeng Sun Peiyi Li Xiaofang Pan Mingjun Huang Baoyang Lu Jun Chen Lidong Wu | 2023 | InfoMat2023，5，7： | 1 |
| 10 | Environmental surveillance of SARS-CoV-2 RNA in wastewater systems and related environments in Wuhan:April to May of 2020显示文摘Wastewater-based epidemiology(WBE)has emerged as an effective environmental surveillance tool in monitoring fecal-oral pathogen infections within a community.Congruently,SARS-Co V-2,the etiologic agent of COVID-19,has been demonstrated to infect the gastrointestinal tissues,and be shed in feces.In the present study,SARS-Co V-2 RNA was concentrated from wastewater,sludge,surface water,ground water,sediment,and soil samples of municipal and hospital wastewater systems and related environments in Wuhan during the COVID-19 middle and low risk periods,and the viral RNA copies quantified using reverse transcription quantitative polymerase chain reaction(RT-q PCR).From the findings of this study,during the middle risk period,one influent sample and three secondary effluents collected from waste water treatment plant 2,as well as two samples from Jinyintan Hospital wastewater system influent were SARS-Co V-2 RNA positive.One sludge sample collected from Guanggu Branch of Tongji Hospital,which was obtained during the low risk period,was also positive for SARS-Co V-2 RNA.These study findings demonstrate the significance of WBE in continuous surveillance of SARS-Co V-2 at the community level,even when the COVID-19 prevalence is low.Overall,this study can be used as an important reference for contingency management of wastewater treatment plants and COVID-19 prevention and control departments of Wuhan. | Lu Zhao Evans Atoni Raphael Nyaruaba Yao Du Huaiyu Zhang Oscar Donde Doudou Huang Shuqi Xiao Nanjie Ren Teng Ma Zhu Shu Zhiming Yuan Lei Tong Han Xia | 2022 | Journal of Environmental Sciences2022，34，2： | 1 |
| 11 | Identification of African swine fever virus MGF505-2R as a potent inhibitor of innate immunity in vitro显示文摘African swine fever(ASF)is etiologically an acute,highly contagious and hemorrhagic disease caused by African swine fever virus(ASFV).Due to its genetic variation and phenotypic diversity,until now,no efficient commercial vaccines or therapeutic options are available.The ASFV genome contains a conserved middle region and two flexible ends that code for five multigene families(MGFs),while the biological functions of the MGFs are not fully characterized.Here,ASFV MGF505-2R-deficient mutant ASFV-Δ2R was constructed based on a highly virulent genotype II field isolate ASFV CN/GS/2018 currently circulating in China.Transcriptomic profiling demonstrated that ASFV-Δ2R was capable of inducing a larger number of differentially expressed genes(DEGs)compared with ASFV CN/GS/2018.Hierarchical clustering of up-regulated DEGs revealed that ASFV-Δ2R induced the most dramatic expression of interferon-related genes and inflammatory and innate immune genes,as further validated by RT-qPCR.The GO and KEGG pathway analysis identified significantly enriched pathways involved in pathogen recognition and innate antiviral immunity.Conversely,pharmacological activation of those antiviral immune responses by exogenous cytokines,including type I/II IFNs,TNF-αand IL-1β,exerted combinatory effects and synergized in antiviral capacity against ASFV replication.Collectively,MGF505-2R is a newly identified inhibitor of innate immunity potentially implicated in immune evasion. | Huaguo Huang Wen Dang Zhengwang Shi Mingyang Ding Fan Xu Tao Li Tao Feng Haixue Zheng Shuqi Xiao | 2023 | Virologica Sinica2023，38，1： | 0 |
| 12 | Breaking the symmetry of colloidal 2D nanoplatelets:Twist induced quantum coupling显示文摘Twist provides a new degree of freedom for nanomaterial modifications,which can provide novel physical properties.Here,colloidal two-dimensional(2D)twisted CdSe nanoplatelets(NPLs)are successfully fabricated and their morphology can change from totally flat to edge-twisted,and then to middle-twisted with prolonged reaction time.By combining experiments and corresponding theoretical analyses,we have established the length-dependent relationships between the surface energy and twist,with a critical lateral dimension of 30 nm.We found that the defects formed during the synthesis process play a vital role in generating intense stress that develops a strong torsion tensor around the edges,resulting in edge-twisted and final middletwisted NPLs.Furthermore,due to the geometric asymmetry of twisted NPLs,the dissymmetry factor of single particle NPLs can reach up to 0.334.Specifically,quantum coupling occurs in middle-twisted NPLs by twisting one parent NPL into two daughter NPLs,which are structurally and electronically coupled.This work not only further deepens our understanding of the twist mechanism of 2D NPLs during colloidal synthesis,but also opens a pathway for applications using twistronics and quantum technology. | Zahid Nazir Yingzhuo Lun Jialu Li Gaoling Yang Mingrui Liu Shuqi Li Gang Tang Guofeng Zhang Jiawang Hong Liantuan Xiao Haizheng Zhong | 2023 | Nano Research2023，16，7： | 0 |

| 14 | Ginkgo biloba extract protects against depression-like behavior in mice through regulating gut microbial bile acid metabolism显示文摘Depression is a mental disorder with high morbidity,disability and relapse rates.Ginkgo biloba extract(GBE),a traditional Chinese medicine,has a long history of clinical application in the treatment of cerebral and mental disorders,but the key mechanism remains incompletely understood.Here we showed that GEB exerted anti-depressant effect in mice through regulating gut microbial metabolism.GBE protected against unpredictable mild stress(UMS)-induced despair,anxiety-like and social avoidance behavior in mice without sufficient brain distribution.Fecal microbiome transplantation transmitted,while antibiotic cocktail abrogated the protective effect of GBE.Spatiotemporal bacterial profiling and metabolomics assay revealed a potential involvement of Parasutterella excrementihominis and the bile acid metabolite ursodeoxycholic acid(UDCA)in the effect of GBE.UDCA administration induced depression-like behavior in mice.Together,these findings suggest that GBE acts on gut microbiome-modulated bile acid metabolism to alleviate stress-induced depression. | ZHOU Junchi FAN Qilin CAI Xiaoying ZHANG Youying HOU Yuanlong CAO Shuqi LIZiguang FENG Mengzhen WANG Qingqing ZHANG Jianbing WANG Guangi ZHENG Xiao HAO Haiping | 2023 | Chinese Journal of Natural Medicines2023，21，10： | 0 |
| 15 | Genomic similarity and antibody-dependent enhancement of immune serum potentially affect the protective efficacy of commercial MLV vaccines against NADC30-like PRRSV显示文摘Porcine reproductive and respiratory syndrome(PRRS)is one of the most significant diseases affecting the pig industry worldwide.The PRRSV mutation rate is the highest among the RNA viruses.To date,NADC30-like PRRSV and highly pathogenic PRRSV(HP-PRRSV)are the dominant epidemic strains in China;however,commercial vaccines do not always provide sufficient cross-protection,and the reasons for insufficient protection are unclear.This study isolated a wild-type NADC30-like PRRSV,SX-YL1806,from Shaanxi Province.Vaccination challenge experiments in piglets showed that commercial modified live virus(MLV)vaccines provided good protection against HP-PRRSV.However,it could not provide sufficient protection against the novel strain SXYL1806.To explore the reasons for this phenomenon,we compared the genomic homology between the MLV strain and HP-PRRSV or NADC30-like PRRSV and found that the MLV strain had a lower genome similarity with NADC30-like PRRSV.Serum neutralization assay showed that MLV-immune serum slightly promoted the homologous HP-PRRSV replication and significantly promoted the heterologous NADC30-like PRRSV strain replication in vitro,suggesting that antibody-dependent enhancement(ADE)might also play a role in decreasing MLV protective efficacy.These findings expand our understanding of the potential factors affecting the protective effect of PRRSV MLV vaccines against the NADC30-like strains. | Yang Li Lele Xu Dian Jiao Zifang Zheng Zhihao Chen Yang Jing Zhiwei Li Zhiqian Maa Yingtong Feng Xuyang Guo Yumiao Wang Yuan He Haixue Zheng Shuqi Xiao | 2023 | Virologica Sinica2023，38，5： | 0 |
