1Pediatric reference intervals in China(PRINCE):design and rationale for a large,multicenter collaborative cross-sectional study显示文摘There is a lack of accurate pediatric reference intervals(RIs) in China, with most commonly used RIs established without consideration of the effect of age and gender. The Pediatric Reference Intervals in China(PRINCE) project aims to establish and verify pediatric RIs for 31 common laboratory measurands.The project will be a large, multicenter cross-sectional study:14,490 healthy children and adolescents aged up to 19 years will be surveyed by 10 children's hospitals and one pediatric department of a university hospital. To evaluate the feasibility and efficiency of the study methods, 602 children were surveyed in the pilot phase of the PRINCE study in April 2017: it found that some measurands were distinctly age dependent and that there were differences between values for males and females. The results of the pilot study affirmed the necessity of the PRINCE project for Chinese pediatrics. The pilot also indicated potential difficulties in the full survey, e.g., difficulties in recruiting children aged under 3 years and insufficient collection of blood samples from infants. The operation of the PRINCE project has been modified based on the findings in the pilot study toward improving the validity of the PRINCE project and promoting its openness and transparency.Xin Ni Wenqi Song Xiaoxia Peng Ying Shen Yaguang Peng Qiliang Li Yan Wang Lixin Hu Yanying Cai Hong Shang Min Zhao Hong Jiang Yaoguo Huang Runqing Mu Wenxiang Chen Mingting Peng Chuanbao Zhang Jie Zeng Chenbin Li Hongling Yang Yongmei Jiang Jin Xu Guixia Li Hongbing Chen Yun Xiang Sancheng Cao Zhenxin Guo Dapeng Chen 2018Science Bulletin2018,63,24:12
2Homogenized Daily Relative Humidity Series in China during 1960?2017显示文摘Surface relative humidity(RH)is a key element for weather and climate monitoring and research.However,RH is not as commonly applied in studying climate change,partly because the observation series of RH are prone to inhomogeneous biases due to non-climate changes in the observation system.A homogenized dataset of daily RH series from 746 stations in Chinese mainland for the period 1960–2017,ChinaRHv1.0,has been developed.Most(685 or 91.82%of the total)station time series were inhomogeneous with one or more break points.The major breakpoints occurred in the early 2000s for many stations,especially in the humid and semi-humid zones,due to the implementation of automated observation across the country.The inhomogeneous biases in the early manual records before this change are positive relative to the recent automatic records,for most of the biased station series.There are more break points detected by using the MASH(Multiple Analysis of Series for Homogenization)method,with biases mainly around?0.5%and 0.5%.These inhomogeneous biases are adjusted with reference to the most recent observations for each station.Based on the adjusted observations,the regional mean RH series of China shows little long-term trend during 1960–2017[0.006%(10 yr)^?1],contrasting with a false decreasing trend[?0.414%(10 yr)?1]in the raw data.It is notable that ERA5 reanalysis data match closely with the interannual variations of the raw RH series in China,including the jump in the early 2000s,raising a caveat for its application in studying climate change in the region.Zhen LI Zhongwei YAN Yani ZHU Nicolas FREYCHET Simon TETT 2020Advances in Atmospheric Sciences2020,37,4:7
3Immunity-and-matrix-regulatory cells derived from human embryonic stem cells safely and effectively treat mouse lung injury and fibrosis显示文摘Lung injury and fibrosis represent the most significant outcomes of severe and acute lung disorders,including COVID-19.However,there are still no effective drugs to treat lung injury and fibrosis.In this study,we report the generation of clinical-grade human embryonic stem cells(hESCs)-derived immunity-and matrix-regulatory cells(IMRCs)produced under good manufacturing practice requirements,that can treat lung injury and fibrosis in vivo.We generate IMRCs by sequentially differentiating hESCs with serum-free reagents.IMRCs possess a unique gene expression profile distinct from that of umbilical cord mesenchymal stem cells(UCMSCs),such as higher expression levels of proliferative,immunomodulatory and anti-fibrotic genes.Moreover,intravenous delivery of IMRCs inhibits both pulmonary inflammation and fibrosis in mouse models of lung injury,and significantly improves the survival rate of the recipient mice in a dose-dependent manner,likely through paracrine regulatory mechanisms.IMRCs are superior to both primary UCMSCs and the FDA-approved drug pirfenidone,with an excellent efficacy and safety profile in mice and monkeys.In light of public health crises involving pneumonia,acute lung injury and acute respiratory distress syndrome,our findings suggest that IMRCs are ready for clinical trials on lung disorders.Jun Wu Dingyun Song Zhongwen Li Baojie Guo Yani Xiao Wenjing Liu Lingmin Liang Chunjing Feng Tingting Gao Yanxia Chen Ying Li Zai Wang Jianyan Wen Shengnan Yang Peipei Liu Lei Wang Yukai Wang Liang Peng Glyn Nigel Stacey Zheng Hu Guihai Feng Wei Li Yan Huo Ronghua Jin Ng Shyh-Chang Qi Zhou Liu Wang Baoyang Hu Huaping Dai Jie Hao 2020Cell Research2020,30,9:7
4Scalable and ultrafast epitaxial growth of single-crystal graphene wafers for electrically tunable liquid-crystal microlens arrays显示文摘The scalable growth of wafer-sized single-crystal graphene in an energy-efficient manner and compatible with wafer process is critical for the killer applications of graphene in high-performance electronics and optoelectronics. Here, ultrafast epitaxial growth of single-crystal graphene wafers is realized on singlecrystal Cu90Ni10(1 1 1) thin films fabricated by a tailored two-step magnetron sputtering and recrystallization process. The minor nickel(Ni) content greatly enhances the catalytic activity of Cu, rendering the growth of a 4 in. single-crystal monolayer graphene wafer in 10 min on Cu90Ni10(1 1 1), 50 folds faster than graphene growth on Cu(1 1 1). Through the carbon isotope labeling experiments, graphene growth on Cu90Ni10(1 1 1) is proved to be exclusively surface-reaction dominated, which is ascribed to the Cu surface enrichment in the Cu Ni alloy, as indicated by element in-depth profile. One of the best benefits of our protocol is the compatibility with wafer process and excellent scalability. A pilot-scale chemical vapor deposition(CVD) system is designed and built for the mass production of single-crystal graphene wafers, with productivity of 25 pieces in one process cycle. Furthermore, we demonstrate the application of single-crystal graphene in electrically controlled liquid-crystal microlens arrays(LCMLA), which exhibit highly tunable focal lengths near 2 mm under small driving voltages. By integration of the graphene based LCMLA and a CMOS sensor, a prototype camera is proposed that is available for simultaneous light-field and light intensity imaging. The single-crystal graphene wafers could hold great promising for highperformance electronics and optoelectronics that are compatible with wafer process.Bing Deng Zhaowei Xin Ruiwen Xue Shishu Zhang Xiaozhi Xu Jing Gao Jilin Tang Yue Qi Yani Wang Yan Zhao Luzhao Sun Huihui Wang Kaihui Liu Mark H.

5Prenatal ultrasonographic characteristics and prognosis of isolated redundant foramen ovale flap显示文摘Objective:To analyze the prenatal ultrasonographic characteristics and prognosis of the isolated redundant foramen ovale flap(RFOF).Methods:From January 2014 to December 2021,we collected data on fetal echocardiography analyses and perinatal outcomes for fetuses with isolated RFOF in Peking University People's Hospital.Results:We found that 0.31%(87/28308)of participants have RFOF.The four-chamber results of the foramen ovale flap(FOF)showed that it was stiff and extended>50%or reached the lateral wall of the left atrium(LA)in diastole.As seen from the foramen ovale(FO)channel and four-chamber views,the hypermobile and redundant flap were observed shrinking and stretching with the fetal cardiac cycle,which is similar to jellyfish.The lateral displacement of flow from LA to the left ventricle(LV)around the FOF on color doppler demonstrated thin linear blood flow from the right to left and a reversal of flow across FO.A uniphasic,but not biphasic,pattern of FOF displacement was observed on M-mode.Stages I(23/87)and II(51/87)had a higher ratio of ventricular disproportion than Stage 0(11/87)and III(2/87).We observed the RA/LA(right/left atrium)>1.2 in 53 cases(60.9%),RV/LV(right/left ventricle)>1.2 in 53 cases(60.9%),PA/AO(pulmonary/aortic artery)>1.2 in 53 cases(60.9%),and moderate or severe tricuspid regurgitation in 10 cases and moderate pericardial effusion in 2 cases(2.2%).Seventy-four RFOF cases had follow-up data.Neonatal death occurred in 2 cases;72 fetuses survived with normal or minor heart defects.Conclusion:RFOF should be considered if the left side of the heart of a fetus is smaller and related to hypermobile FOF.For isolated RFOF cases,a monthly follow-up is recommended to monitor arrhythmia or fetal hydrop status.Prompt treatment is recommended for those with adequate gestational age and lung maturity.Yuntao Li Qiuyan Pei Zhenjuan Yang Yani Yan Xiaowei Xue 2022Gynecology and Obstetrics Clinical Medicine2022,2,3:1
6Effect of Ti layer thickness on microstructure and magnetic properties of Ti/Co/Ti films显示文摘TiCoTi granular films were prepared by DC facing-target magnetron sputtering system onto glass substrates and subsequently in situ annealing in vacuum. Structural of Ti (t nm)/Co (40 nm)/Ti (t nm) films were investigated in detail, which shows that the majority Co nanograins are formed as the hexagonal-close-packed (HCP) structure. Vibrating sample magnetometer (VSM) and scanning probe microscope (SPM) were applied to study the magnetic properties, morphologies and domain structures of these samples. It has been found that the structure and magnetic properties of the Ti/Co/Ti films depend strongly on the Ti layer thickness. The out-of-plane coercivities (Hc) of the film is maximum about 78.8 kA·m-1 when t=5 nm with annealing at 300 ℃; the distributing of grains of the sample is uniformity; and the average size of particles is about 13 nm. The obtained results suggest that this system is perpendicular anisotropy and might be applicable to perpendicular magnetic recording media.ZHANG Yujie ZHANG Hanwei FENG Shunzhen SUN Huiyuan HU Yanying PENG Yan 2006Rare Metals2006,25,z1:1

8High-energy-density plasma in femtosecond-laser-irradiated nanowire-array targets for nuclear reactions显示文摘In this work,the high-energy-density plasmas(HEDP)evolved from joule-class-femtosecond-laser-irradiated nanowire-array(NWA)targets were numerically and experimentally studied.The results of particle-in-cell simulations indicate that ions accelerated in the sheath field around the surfaces of the nanowires are eventually confined in a plasma,contributing most to the high energy densities.The protons emitted from the front surfaces of the NWA targets provide rich information about the interactions that occur.We give the electron and ion energy densities for broad target parameter ranges.The ion energy densities from NWA targets were found to be an order of magnitude higher than those from planar targets,and the volume of the HEDP was several-fold greater.At optimal target parameters,8%of the laser energy can be converted to confined protons,and this results in ion energy densities at the GJ/cm^(3) level.In the experiments,the measured energy of the emitted protons reached 4 MeV,and the changes in energy with the NWA’s parameters were found to fit the simulation results well.Experimental measurements of neutrons from 2H(d,n)3He fusion with a yield of(24±18)×10^(6)/J from deuterated polyethylene NWA targets also confirmed these results.Defeng Kong Guoqiang Zhang Yinren Shou Shirui Xu Zhusong Mei Zhengxuan Cao Zhuo Pan Pengjie Wang Guijun Qi Yao Lou Zhiguo Ma Haoyang Lan Wenzhao Wang Yunhui Li Peter Rubovic Martin Veselsky Aldo Bonasera Jiarui Zhao Yixing Geng Yanying Zhao Changbo Fu Wen Luo Yugang Ma Xueqing Yan Wenjun Ma 2022Matter and Radiation at Extremes2022,7,6:1

12Ultrafast growth of wafer-scale fold-free bilayer graphene显示文摘Bilayer graphene provides a versatile platform for exploring a variety of intriguing phenomena and shows much promise for applications in electronics,optoelectronics,etc.Controlled growth of large-area bilayer graphene is therefore highly desired yet still suffers from a slow growth rate and poor layer uniformity.Meanwhile,graphene wrinkles,including folds and ripples,form during cooling due to the thermal contraction mismatch between graphene and the metal substrates,and have been far from suppressed or eliminated,especially in bilayer graphene,which would greatly degrade the extraordinary properties of graphene.Here we report the ultrafast growth of wafer-scale fold-free bilayer graphene by chemical vapor deposition.Through well-tuning the alloy thickness and strain regulation of the single-crystal CuNi(111)/sapphire,the full coverage of a 2-inch fold-free bilayer graphene wafer via mainly isothermal segregation has been achieved as fast as 30 s.The tensile-strained CuNi(111)film reduces the thermal contraction mismatch and suppresses the formation of graphene folds during cooling,which is directly observed through in situ optical microscopy.The ultraflat bilayer graphene exhibits wafer-scale uniformity in electrical performance and enhanced mechanical property comparable to the exfoliated ones.Our results offer a promising route for largescale production of bilayer graphene and enable its various applications.Jilin Tang Yuechen Wang Yuwei Ma Xiaoyin Gao Xin Gao Ning Li Yani Wang Shishu Zhang Liming Zheng Bing Deng Rui Yan Yisen Cao Ronghua Zhang Lianming Tong Jin Zhang Peng Gao Zhongfan Liu Xiaoding Wei Hongtao Liu Hailin Peng 2023Nano Research2023,16,7:0
13Geochemical behavior of lithium isotopes in a small mountainous river of the Tibetan Plateau:A case study from Niyang River显示文摘Lithium(L_(i))and its isotopes are potential tracers of silicate weathering in river basins.However,the relationship between the Li isotopic composition(δ~7Li)in rivers and silicate weathering intensity remains unclear.This study analyzed the Li concentration and isotopic composition in river waters from the Niyang River,southern Tibetan Plateau.The results show that these samples have significantly variable Li concentrations(0.31–7.4μg/L)andδ~7Li values(+7.0–+20.7‰,n=28),and highδ~7Li values are found in several tributaries.Calculations indicate that dissolved Li in river water is predominantly derived from silicate weathering and geothermal water.With the exception of certain tributaries,geothermal water contributes 68%to 85%of the dissolved Li.Geothermal waters have lowδ~7Li values(-0.9–+2.9‰)in the Tibetan Plateau.Differences in the proportional contribution of dissolved Li in river samples from silicate weathering and geothermal water may be the main reason for the spatiotemporal variation in riverineδ~7Li values.The samples have higherδ~7Li values when the dissolved Li in the water samples is mainly derived from silicate weathering contributions,and lower values when the contribution from geothermal waters is high.Furthermore,the interaction of dissolved Li from geothermal water with secondary minerals results in Li isotopic fractionation,which may contribute to variations in river waterδ~7Li.It is accepted that the lower weathering intensity in orogenic(or mountainous)belts compared to floodplains is the main controlling factor for lowerδ~7Li values in the rivers.This study indicates that geothermal water input may cover the Li isotope signal of silicate weathering in river water,which in turn,affects the accurate understanding of the relationship between riverineδ~7Li values and the silicate weathering intensity.Therefore,whether the lowerδ~7Li values of river waters in hydrothermal-rich orogenic belts are mainly controlled by the regional weathering intensity or the input of hot springs(or both)requires in-depth study,and this is the key to accurately establishing the relationship between the Li isotopic composition and silicate weathering intensity in the river basin.Junwen ZHANG Yani YAN Zhiqi ZHAO Congqiang LIU 2023Science China Earth Sciences2023,66,8:0
14Immunity-and-matrix-regulatory cells enhance cartilage regeneration for meniscus injuries: a phase I dose-escalation trial显示文摘Immunity-and-matrix-regulatory cells(IMRCs)derived from human embryonic stem cells have unique abilities in modulating immunity and regulating the extracellular matrix,which could be mass-produced with stable biological properties.Despite resemblance to mesenchymal stem cells(MSCs)in terms of self-renew and tri-lineage differentiation,the ability of IMRCs to repair the meniscus and the underlying mechanism remains undetermined.Here,we showed that IMRCs demonstrated stronger immunomodulatory and pro-regenerative potential than umbilical cord MSCs when stimulated by synovial fluid from patients with meniscus injury.Following injection into the knees of rabbits with meniscal injury,IMRCs enhanced endogenous fibrocartilage regeneration.In the dose-escalating phase I clinical trial(NCT03839238)with eighteen patients recruited,we found that intra-articular IMRCs injection in patients was safe over 12 months post-grafting.Furthermore,the effective results of magnetic resonance imaging(MRI)of meniscus repair and knee functional scores suggested that 5×107 cells are optimal for meniscus injury treatment.In summary,we present the first report of a phase I clinical trial using IMRCs to treat meniscus injury.Our results demonstrated that intra-articular injection of IMRCs is a safe and effective therapy by providing a permissive niche for cartilage regeneration.Liangjiang Huang Song Zhang Jun Wu Baojie Guo Tingting Gao Sayed Zulfiqar Ali Shah Bo Huang Yajie Li Bo Zhu Jiaqi Fan Liu Wang Yani Xiao Wenjing Liu Yao Tian Zhengyu Fang Yingying Lv Lingfeng Xie Sheng Yao Gaotan Ke Xiaolin Huang Ying Huang Yujuan Li Yi Jia Zhongwen Li Guihai Feng Yan Huo Wei Li Qi Zhou Jie Hao Baoyang Hu Hong Chen 2023Signal Transduction and Targeted Therapy2023,8,12:0
15Fabrication of Ceramic-Polymer Piezo-Composites with Triply Periodic Minimal Interfaces via Digital Light Processing显示文摘The geometry of the phase interface in co-continuous piezoelectric composites is critical in improving their piezo-electric properties.However,conventional co-continuous piezoelectric composites are mostly simple structures such as wood stacks or honeycombs,which are prone to stress concentrations at the joints,thus reducing the fatigue service performance and force-electric conversion efficiency of piezoelectric composites.Such simple structures limit further improvements in the overall performance of co-continuous piezoelectric composites.In this study,based on the digital light processing 3D printing method,we investigated the influence of three dif-ferent structures-the gyroid,diamond,and woodpile interfaces-on the piezoelectric and mechanical properties of co-continuous ceramic/polymer piezoelectric composites.These findings demonstrate that the gyroid and di-amond interfaces outperformed the ceramic skeleton of the woodpile interface in terms of both mechanical and electrical properties.When the ceramic volume percentage was 50%,the piezo-composite of the gyroid surface exhibited the greatest hydrostatic figure of merit(HFOM),reaching 4.23×10^(−12) Pa^(−1),and its piezoelectric coeffi-cient(d_(33))and relative dielectric constant(εr)reached 115 pC/N and 748,respectively.The research results lay the foundation for the application of co-continuous piezoelectric composites in underwater communication and detection.Kai Liu Junchao He Tianyang Li Jiaming Hu Yanying Du Yusheng Shi Chunzhe Yan Zhangwei Chen Shangyu Huang Huajun Sun 2023Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2023,2,4:0
16A novel molecular mechanism for nitrated α-synuclein-induced cell death显示文摘Although previous studies have demonstrated the involvement of nitrated a-synuclein in neurodegenerative disorders(synucleinopathies),the effects of nitrated α-synuclein and the molecular mechanisms underlying its toxicity are still unclear.In the present study,nitrated α-synuclein with four 3-nitrotyrosines(Tyr^(39),Tyr^(125),Tyr^(133),and Tyr^(136))was obtained non-enzymatically by incubation with nitrite.The nitrated protein existed as a mixture of monomers,dimers,and polymers in solution.The nitrated a-synuclein could induce cell death in a time-and concentration-dependent manner when SH-SY5Y cells(a human neuroblastoma cell line)were incubated with the dimers and polymers.Treatment with anti-integrin α5β1 antibody partially rescued the SH-SY5Y cells from the cell death.Dot blotting and immunoprecipitation revealed that the nitrated protein bound to integrin on the cell membranes.Level of nitric oxide(NO)and calcium-independent inducible NO synthase(iNOS)activity increased during the initial stages of the treatment.The expression of phosphorylated focal adhesion kinase(FAK)decreased in the cells.Subsequently,an increase in caspase 3 activity was observed in SH-SY5Y cells.Our results demonstrate that activation of iNOS and inhibition of FAK may both be responsible for the cell death induced by nitrated α-synuclein.These data suggest that the cytotoxicity of nitrated a-synuclein is mediated via an integrin-iNOS/-FAK signaling pathway,and that the nitration of α-synuclein plays a role in neuronal degeneration.Yanying Liu Min Qiang Yan Wei Rongqiao He 2011Journal of Molecular Cell Biology2011,3,4:0
17Safety,immunogenicity,and preliminary efficacy of a randomized clinical trial ofomicron XBB.1.5-containing bivalent mRNA vaccine显示文摘Periodically updating coronavirus disease 19(COVID-19)vaccines that offer broad-spectrum protection is needed giventhe strong immune evasion by the circulating omicron sublineages.The effectiveness of prototype and BA.4/5-containing bivalent mRNA vaccines is reduced when XBB subvariants predominate.We initiated an observer-blinded,threearms study in 376 patients in Chinese individuals aged from 18 to 55 years old who had previously received three dosesCOVID-19 vaccine.Immunogenicity in terms of neutralizing antibodies elicited by a 30-mg dose of XBB.1.5-containingbivalent vaccine(RQ3027),a 30-mg dose of BA.2/BA.5-Alpha/Beta bivalent vaccine(RQ3025)and their precedent 30-mg Alpha/Beta(combined mutations)monovalent mRNA vaccine(RQ3013)and safety are primary and secondary endpoints,respectively.We recorded prescribed COVID-19 cases to explore the preliminary efficacy of three vaccines.RQ3027 and RQ3025 boosters elicited superior neutralizing antibodies(NAbs)against XBB.1.5,XBB.1.16,XBB.1.9.1,and JN.1 compared to RQ3013 at day 14 in participants without SARS-CoV-2 infection.All study vaccines were welltolerated without serious adverse reactions identified.The incidence rates per 1000 person-years of COVID-19 casesduring the 2nd-19th week after randomization were lowest in RQ3027.Overall,our data show that XBB.1.5-containingbivalent booster generated superior immunogenicity and better protection against newer severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)variants compared to BA.2/BA.5-containing bivalent and Alpha/Beta monovalentwith no new safety concerns.Xuanjing Yu Wei Yang Wei Li Na Wan Guanghong Yan Zumi Zhou Xiao Zhu Wei Su Yani Li Chenyu Xing Sifan Duan Houze Yu Xinshuai Zhao Chunmei Li Taicheng Zhou Dingyun You Jia Wei Zijie Zhang 2024hLife2024,2,3:0
18T790M mutation in stage IV EGFR-mutated NSCLC patient with acquired resistance reverted to original 19Del mutation after administration of a series of precision treatments:a case report显示文摘Existing studies have yet to elucidate clearly the mechanisms of secondary resistance to third generation epidermal growth factor receptor(EGFR)tyrosine kinase inhibitors(TKIs),neither is there any established standard therapy for patients resistant to third generation EGFR-TKIs.This case report demonstrates a rare mutation pattern in a male patient with a pathologic diagnosis of non-small cell lung cancer(NSCLC)harboring an EGFR exon 19 deletion(19Del)mutation,who then acquired an EGFR-T790M mutation after developing resistance to the first generation EGFR-TKI(gefitinib).The mutation reverted to the original EGFR-19Del mutation after the patient developed secondary resistance against the third generation TKI(osimertinib).This patient eventually achieved partial response(PR)with second generation TKI(afatinib)as a fourth-line treatment.Jialong Han Ya Wang Lili Zhong Huijie Zhou Min Yu Yanying Li You Lu Yan Wang Jiang Zhu 2018Precision Clinical Medicine2018,1,3:0
19肝胆肿瘤中肿瘤特异性CircRNA衍生抗原肽的鉴定显示文摘基于肿瘤抗原的免疫治疗的应用受到验证免疫原性肽稀缺性的阻碍。本研究旨在研究环状RNA(circRNA)在肝胆肿瘤类器官中作为肿瘤抗原肽新来源的潜力。使用RNA测序(RNA-seq)和基于算法的评分工具,预测3950个翻译的肿瘤特异性环状RNA在27个类器官中产生18971个抗原肽。从抗原格局来看,11个氨基酸长度(mer)肽和人白细胞抗原(HLA)-A结合肽具有最高的免疫原性相关评分。在分析的3/5类器官中,有13个预测抗原肽通过质谱(MS)免疫肽组学被直接确认为HLA-A、HLA-B和HLA-C(HLA-ABC)结合肽。在流式细胞术和酶联免疫吸附试验(ELISA)中,由HLA-ABC分子呈递的circRNA衍生的肿瘤特异性肽刺激CD8(CD8)T细胞,显示CD107a干扰素γ(IFNγ)共表达和IFNγ分泌增加。免疫原性环状RNA衍生肽诱导的靶向类器官的细胞毒性T细胞活性在杀伤实验中得到验证。值得注意的是,来自circTBC1D15的抗原肽YGFNEILKK不仅被认为是类器官的HLA-ABC呈递肽,而且还显著降低了肿瘤类器官的存活率。本研究的发现强调了产生肿瘤抗原的一个关键亚群,这对靶向肿瘤特异性circRNA具有重要意义。Wenwen Wang Lili Ma Zheng Xing Tinggan Yuan Jinxia Bao Yanjing Zhu Xiaofang Zhao Yan Zhao Yali Zong Yani Zhang Siyun Shen Xinyao Qiu Shuai Yang 王红阳 高栋 王鹏 陈磊 2023Engineering2023,,3:0
20A Review of the Engineering Role of Burrowing Animals: Implication of Chinese Pangolin as an Ecosystem Engineer显示文摘Ecosystem engineers are organisms that alter the distribution of resources in the environment by creating,modifying,maintaining and/or destroying the habitat.They can affect the structure and function of the whole ecosystem furthermore.Burrowing engineers are an important group in ecosystem engineers as they play a critical role in soil translocation and habitat creation in various types of environment.However,few researchers have systematically summarized and analyzed the studies of burrowing engineers.We reviewing the existing ecological studies of burrowing engineer about their interaction with habitat through five directions:(1)soil turnover;(2)changing soil physicochemical properties;(3)changing plant community structure;(4)providing limited resources for commensal animals;and/or(5)affecting animal communities.The Chinese pangolin(Manis pentadactyla)is a typical example of burrowing mammals,in part(5),we focus on the interspecific relationships among burrow commensal species of Chinese pangolin.The engineering effects vary with environmental gradient,literature indicates that burrowing engineer play a stronger role in habitat transformation in the tropical and subtropical areas.The most common experiment method is comparative measurements(include different spatial and temporal scale),manipulative experiment is relatively few.We found that most of the engineering effects had positive feedback to the local ecosystem,increased plant abundance and resilience,increased biodiversity and consequently improved ecosystem functioning.With the global background of dramatic climate change and biodiversity loss in recent decades,we recommend future studies should improving knowledge of long-term engineering effects on population scale and landscape scale,exploring ecological cascades through trophic and engineering pathways,to better understand the attribute of the burrowing behavior of engineers to restore ecosystems and habitat creation.The review is presented as an aid to systematically expound the engineering effect of burrowing animals in the ecosystem,and provided new ideas and advice for planning and implementing conservation management.Song Sun Hongliang Dou Shichao Wei Yani Fang Zexu Long Jiao Wang Fuyu An Jinqian Xu Tingting Xue Huangjie Qiu Yan Hua Guangshun Jiang 2021Journal of Zoological Research2021,3,3:0
