| 1 | The wonders of BMP9:From mesenchymal stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism to regenerative medicine显示文摘Although bone morphogenetic proteins(BMPs)initially showed effective induction of ectopic bone growth in muscle,it has since been determined that these proteins,as members of the TGF-b superfamily,play a diverse and critical array of biological roles.These roles include regulating skeletal and bone formation,angiogenesis,and development and homeostasis of multiple organ systems.Disruptions of the members of the TGF-b/BMP superfamily result in severe skeletal and extra-skeletal irregularities,suggesting high therapeutic potential from understanding this family of BMP proteins.Although it was once one of the least characterized BMPs,BMP9 has revealed itself to have the highest osteogenic potential across numerous experiments both in vitro and in vivo,with recent studies suggesting that the exceptional potency of BMP9 may result from unique signaling pathways that differentiate it from other BMPs.The effectiveness of BMP9 in inducing bone formation was recently revealed in promising experiments that demonstrated efficacy in the repair of critical sized cranial defects as well as compatibility with bone-inducing bio-implants,revealing the great translational promise of BMP9.Furthermore,emerging evidence indicates that,besides its osteogenic activity,BMP9 exerts a broad range of biological functions,including stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism.This review aims to summarize our current understanding of BMP9 across biology and the body. | Sami Mostafa Mikhail Pakvasa Elam Coalson Allen Zhu Alex Alverdy Hector Castillo Jiaming Fan Alex Li Yixiao Feng Di Wu Elliott Bishop Scott Du Mia Spezia Alissa Li Ofir Hagag Alison Deng Winny Liu Mingyang Li Sherwin S·Ho Aravind Athiviraham Michael J·Lee Jennifer Moriatis Wolf Guillermo A·Ameer Hue H·Luu Rex C·Haydon Jason Strelzow Kelly Hynes Tong-Chuan He Russell R·Reid | 2019 | Genes & Diseases2019,6,3: | 15 |
| 2 | Phosphorylation of PLIN3 by AMPK promotes dispersion of lipid droplets during starvation显示文摘Dear Editor,Lipid droplets(LDs)are dynamic lipid-storage organelles of storage depots and sources of essential substrates for myriad cellular processes and protect cells from lipotoxicity(Ohsaki et al.,2006).Disrupted LD and fat storage homeostasis has been linked to metabolic diseases such as atherosclerosis,obesity,and type II diabetes(Levin et al.,2001).Structurally,the core of neutral lipids in LDs is surroun ded by a phospholipid mono layer and coated with specific proteins(Storey et al.,2011).Perilipin family of proteins are the predominant LD-associated proteins. | Jianxi Zhu Mingyang Xu Yi Liu Lisha Zhuang Kejun Ying Feng Liu Dan Liu Wenbin Ma Zhou Songyang | 2019 | Protein & Cell2019,10,5: | 7 |
| 3 | Distribution and existing state of indium in the Gejiu Tin polymetallic deposit, Yunnan Province, SW China显示文摘The Gejiu tin polymetallic deposit, located in the southwest margin of the South China Belt bordering on the Yangtze Block, is hosted in Triassic carbonates. This study shows that there is an indium enrichment in the ores.Indium mainly exists in sphalerite-rich massive sulfide ores with a concentration of 198.3–1570 ppm; the indium concentration in sphalerite ranges from 493.3 up to4781 ppm. The inferred indium reserve in the Gejiu Sn deposit is over 4000 t, indicating that the Gejiu tin deposit is a giant In-bearing Sn-polymetallic deposit, similar to the Dachang and Dulong in southwest China. Sphalerite with a high Fe value(8.05–13.27 wt%) is the predominant indium carrier mineral; meanwhile chalcopyrite plays the secondary indium carrier role. EPMA mapping result shows that indium is likely distributed homogeneously and presented as a substitution for Zn in sphalerite. | Yubang Li Yan Tao Feilin Zhu Mingyang Liao Feng Xiong Xianze Deng | 2015 | Chinese Journal Of Geochemistry2015,34,4: | 7 |
| 4 | Stem cell therapy for chronic skin wounds in the era of personalized medicine:From bench to bedside显示文摘With the significant financial burden of chronic cutaneous wounds on the healthcare system,not to the personal burden mention on those individuals afflicted,it has become increasingly essential to improve our clinical treatments.This requires the translation of the most recent benchtop approaches to clinical wound repair as our current treatment modalities have proven insufficient.The most promising potential treatment options rely on stem cellbased therapies.Stem cell proliferation and signaling play crucial roles in every phase of the wound healing process and chronic wounds are often associated with impaired stem cell function.Clinical approaches involving stem cells could thus be utilized in some cases to improve a body’s inhibited healing capacity.We aim to present the laboratory research behind the mechanisms and effects of this technology as well as current clinical trials which showcase their therapeutic potential.Given the current problems and complications presented by chronic wounds,we hope to show that developing the clinical applications of stem cell therapies is the rational next step in improving wound care. | Elam Coalson Elliot Bishop Wei Liu Yixiao Feng Mia Spezia Bo Liu Yi Shen Di Wu Scott Du Alexander J.Li Zhenyu Ye Ling Zhao Daigui Cao Alissa Li Ofir Hagag Alison Deng Winny Liu Mingyang Li Rex C.Haydon Lewis Shi Aravind Athiviraham Michael J.Lee Jennifer Moriatis Wolf Guillermo A.Ameer Tong-Chuan He Russell R.Reid | 2019 | Genes & Diseases2019,6,4: | 6 |
| 5 | Underwater three-dimensional imaging using narrowband MIMO array显示文摘To obtain high cross-range resolution, the underwater 3-D acoustic imaging system usually requires a rectangular array with a great number of sensors and a large physical size. To reduce the sensor number and the array physical size simultaneously, this paper proposes a new underwater 3-D acoustic imaging approach based on a novel multiple-input multiple-output (MIMO) array. Specifically, the MIMO array is composed of four uniform linear arrays (ULAs) located on four sides of a rectangle. The transmitting array composed of two ULAs is located on a pair of opposite sides, and the receiving array composed of another two ULAs is located on the other two sides. Furthermore, narrowband waveforms coded with orthogonal polyphase sequences are employed as transmitting waveforms. When the subcode numbers in the polyphase coded sequences are sufficient, the MIMO array has the same 3-D imaging ability as a rectangular array, which has a two-time bigger size than that of the former. Consequently, the MIMO array can not only save a great number of sensors, but halve the array size, when compared to a rectangular array with the same cross-range resolution. Computer simulations are provided to demonstrate the effectiveness of the proposed imaging approach. | LIU XiongHou SUN Chao YI Feng LIU ZongWei LI MingYang | 2013 | Science China(Physics,Mechanics & Astronomy)2013,56,7: | 4 |
| 6 | Study of oxygen fugacity during magma evolution and ore genesis in the Hongge mafic–ultramafic intrusion, the Panxi region, SW China显示文摘Economic concentrations of Fe–Ti oxides occurring as massive layers in the middle and upper parts of the Hongge intrusion are different from other layered intrusions(Panzhihua and Baima) in the Emeishan large igneous province, SW China. This paper reports on the new mineral compositions of magnetite and ilmenite for selected cumulate rocks and clinopyroxene and plagioclase for basalts. We use these data to estimate the oxidation state of parental magmas and during ore formation to constrain the factors leading to the abundant accumulation of Fe–Ti oxides involved with the Hongge layered intrusion. The results show that the oxygen fugacities of parental magma are in the range of FMQ-1.56 to FMQ+0.14, and the oxygen fugacities during the ore formation of the Fe–Ti oxides located in the lower olivine clinopyroxenite zone(LOZ) and the middle clinopyroxenite zone(MCZ) of the Hongge intrusion are in the range of FMQ-1.29 to FMQ-0.2 and FMQ-0.49 to FMQ+0.82, respectively.The MELTS model demonstrates that, as the oxygen fugacity increases from the FMQ-1 to FMQ+1, the proportion of crystallization magnetite increases from 11 % to 16 % and the crystallization temperature of the Fe–Ti oxides advances from 1134 to 1164 °C. The moderate oxygen fugacities for the Hongge MCZ indicate that the oxygen fugacity was not the only factor affecting the crystallization of Fe–Ti oxides. We speculated that theinitial anhydrous magma that arrived at the Hongge shallow magma chamber became hydrous by attracting the H_2O of the strata. In combination with increasing oxygen fugacities from the LOZ(FMQ-1.29 to FMQ-0.2) to the MCZ(FMQ-0.49 to FMQ+0.82), these two factors probably account for the large-scale Fe–Ti oxide ore layers in the MCZ of the Hongge intrusion. | Mingyang Liao Yan Tao Xieyan Song Yubang Li Feng Xiong | 2016 | Acta Geochimica2016,35,1: | 3 |
| 7 | 对比经肛全直肠系膜切除术与腹腔镜全直肠系膜切除术:一项多中心III期随机临床试验(TaLaR试验)方案显示文摘背景:全直肠系膜切除术是直肠癌治疗的标准手术方法。经肛全直肠系膜切除术(taTME)是治疗低位直肠癌的新术式。既往研究表明,与腹腔镜全直肠系膜切除术(lapTME)相比,taTME应用于低位直肠癌患者可提供更高质量的手术标本,但其长期肿瘤学结果仍需进一步观察。因此,我们设计了这个非劣效性临床试验(TaLaR试验),比较taTME与lapTME治疗直肠癌的短期和长期结果。方法/设计:TaLaR试验是一项多中心III期随机对照试验。研究对象为经磁共振成像、直肠指检或结肠镜检查被诊断为位于腹膜反折以下的直肠癌,若肿瘤分期≤cT3N2直接手术,若>cT3N2则先行新辅助治疗。通过计算,本研究需纳入1,114例患者(每组557例)。纳入病例随机分配到taTME或lapTME组。本研究的主要终点是3年无病生存率(DFS)和5年总生存率(OS)。次要终点包括手术标本质量、围手术期结果、骨盆和肛门功能以及生活质量。讨论:我们认为,TaLaR试验将阐明taTME是否可以达到与lapTME相似的肿瘤学结果,以及是否可改善直肠癌患者的手术标本质量及恢复情况。 | Liang Kang Ziwei Zeng Shuangling Luo Hong Zhang Quan Wang Mingyang Ren Miao Wu Weidong Tong Qing Xu Yi Xiao Aiwen Wu Yuan-Guang Chen Bo Feng Zhanlong Shen Liang Huang Xingwei Zhang Minhua Zheng Jian-Ping Wang | 2021 | Gastroenterology Report2021,9,1: | 2 |
| 8 | Detection of Asymptomatic Carotid Artery Stenosis in High-Risk Individuals of Stroke Using a Machine-Learning Algorithm显示文摘Objective Asymptomatic carotid stenosis(ACS)is closely associated to the incidence of severe cerebrovascular diseases.Early identifying the individuals with ACS and its associated risk factors could be beneficial for primary prevention of stroke.This study aimed to investigate a machine-learning algorithm for the detection of ACS among high-risk population of stroke based on the associated risk factors.Methods A novel model of machine learning was utilized to screen the associated predictors of ACS based on 30 potential risk factors.The algorithm of this model adopted a random forest pattern based on the training data and then was verified using the testing data.All of the original data were retrieved from the China National Stroke Screening and Prevention Project(CNSSPP),including demographic,clinical and laboratory characteristics.The individuals with high risk of stroke were enrolled and randomly divided into a training group and a testing group at a ratio of 4:1.The identification of carotid stenosis by carotid artery duplex scans was set as the golden standard.The receiver operating characteristic(ROC)curve and the area under the curve(AUC)was used to evaluate the efficacy of the model in detecting ACS.Results Of 2841 high risk individual of stroke enrolled,326(11.6%)were diagnosed as ACS by ultrasonography.The top five risk fectors contributing to ACS in this model were identified as family history of dyslipidemia,high level of lowdensity lipoprotein cholesterol(LDL-c),low level of high-density lipoprotein cholesterol(HDL-c),aging,and low body. | Junxiong Yin Cheng Yu Lixia Wei Chuanyong Yu Hongxing Liu Mingyang Du Feng Sun Chongjun Wang Xiaoshan Wang | 2020 | Chinese Medical Sciences Journal2020,35,4: | 2 |
| 9 | Risk factors associated with hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation显示文摘Hemorrhagic cystitis(HC)is a common complication of allogeneic hematopoietic stem cell transplantation(HSCT).The incidence is about 7%to 68%,and some patients have to suffer a long period of frequent,urgent,and painful urination,which brings great pain.This study aimed to analyze risk factors of HC and its effect on patient survival.We collected the medical records of 859 patients who underwent HSCT at our hospital between August 2016 and August 2020.Patients with and without HC were matched using propensity score matching at a 1:1 ratio based on sex,age,and diagnosis,and logistic regression analyses were used to identify factors associated with HC.We used Kaplan–Meier curves to analyze the survival rates of patients in the HC and non-HC groups.We also analyzed the relationship between BK viral load and the occurrence of HC using receiver operating characteristic curve(ROC)analysis.After propensity score matching,there were 131 patients each in the HC and non-HC groups.In the HC group,89 patients(67.9%)had mild HC(stage II°)and 43(32.1%)had severe HC(stage III–IV).The median interval between stem cell transplantation and HC development was 31(3–244)days.Univariate analysis indicated that donor age,hematopoietic stem cell source,HLA,acute graft-versus-host disease,busulfan,anti-thymocyte globulin(ATG),total body irradiation,cytomegalovirus(CMV)(urine),and BK polyomavirus(BKV)(urine)were significantly associated with HC.ATG,CMV(urine),and BKV(urine)were independent risk factors for HC based on the multivariate analysis.The Kaplan–Meier survival analysis showed no significant difference between the HC and non-HC groups(P=0.14).The 1-and 2-year survival rates in the HC group were 78.4%and 69.6%,respectively,and the corresponding rates in the non-HC group were 84.4%and 80.7%,respectively.ROC analysis indicated that a urine BKV load of 1×10^(7) copies/mL was able to stratify the risk of HC.In conclusion,when the BKV load is>1×10^(7),we needtobe aware of the potential for the development of HC. | Biao Shen Yueshen Ma Haixiao Zhang Mingyang Wang Jia Liu Jiaxin Cao Wenwen Guo Dan Feng Donglin Yang Rongli Zhang Xin Chen Qiaoling Ma Weihua Zhai Sizhou Feng Mingzhe Han Aiming Pang Erlie Jiang 无 | 2022 | Blood Science2022,4,2: | 2 |
| 10 | Ground surface response induced by shallow buried explosions显示文摘Based on the spherical cavity expansion theory in the elastic half space,the ground surface movement characteristics of shallowly buried explosions are analyzed.The results show that the induced seismic wave is a longitudinal wave in the near zone and a Rayleigh wave in the far zone.The maximum displacement(velocity) of the longitudinal wave and the Rayleigh wave are inversely proportional to the scaled distance,and can be described by exponential function with exponents equal to 1.4 and 0.5,respectively.The vibration frequencies of the waves have almost no change.The vibration frequency of the longitudinal wave approximates the natural vibration frequency of the cavity in the broken area,and the vibration frequency of the Rayleigh wave is about half that of the longitudinal wave.On the same reduced buried depth and reduced distance,the particle displacement is directly proportional to the product of the boundary loading and cavity radius,and is inversely proportional to the transversal wave velocity.Meanwhile,the particle velocity is directly proportional to the boundary loading and inversely proportional to the wave velocity ratio.In the far zone,the buried depth of the explosive only has a slight effect on the longitudinal wave,but has a larger effect on the Rayleigh wave. | Wang Derong Wang Mingyang Li Jie Feng Shufang | 2014 | Earthquake Engineering and Engineering Vibration2014,13,1: | 1 |

| 12 | Ferroptosis and endoplasmic reticulum stress in ischemic stroke显示文摘Ferroptosis is a form of non-apoptotic programmed cell death,and its mechanisms mainly involve the accumulation of lipid peroxides,imbalance in the amino acid antioxidant system,and disordered iron metabolism.The primary organelle responsible for coordinating external challenges and internal cell demands is the endoplasmic reticulum,and the progression of inflammatory diseases can trigger endoplasmic reticulum stress.Evidence has suggested that ferroptosis may share pathways or interact with endoplasmic reticulum stress in many diseases and plays a role in cell survival.Ferroptosis and endoplasmic reticulum stress may occur after ischemic stroke.However,there are few reports on the interactions of ferroptosis and endoplasmic reticulum stress with ischemic stroke.This review summarized the recent research on the relationships between ferroptosis and endoplasmic reticulum stress and ischemic stroke,aiming to provide a reference for developing treatments for ischemic stroke. | Yina Li Mingyang Li Shi Feng Qingxue Xu Xu Zhang Xiaoxing Xiong Lijuan Gu | 2024 | Neural Regeneration Research2024,19,3: | 1 |
| 13 | Divergent responses of plant biomass and diversity to short-term nitrogen and phosphorus addition in three types of steppe in Inner Mongolia,China显示文摘Background:Understanding the response of the plant community to increasing nitrogen(N)and phosphorus(P)inputs is helpful for managing and protecting grassland ecosystems in semiarid areas.However,information about different types of steppe responses to N and P availability in semiarid grasslands is limited.In 2017-2018,two field experiments were conducted with six levels of N(from 5 to 30 g N m^(−2)yr^(−1))and P(from 2.5 g to 15 g P m^(−2)yr^(−1))additions in three different temperate steppes,including meadow steppe(MS),typical steppe(TS),and desert steppe(DS),in northern China to study the effects of these addition rates on community biomass and diversity.Results:Our results showed that plant biomass and diversity in the three steppe types in Inner Mongolia responded differently to elevated N and P inputs.Increasing P promoted aboveground and belowground biomass more than increasing N in the three temperate steppes.Short-term N and P additions reduced plant diversity to some extent,with the most pronounced decreases in MS and DS.It is noteworthy that there were response thresholds for plant diversity and biomass in response to N and P inputs in different steppe types(e.g.,10 g P m^(−2)yr^(−1)).Furthermore,redundancy analysis and stepwise regression analysis revealed that changes in soil properties induced by nutrient addition and climate conditions jointly regulated changes in vegetation biomass and diversity.Conclusions:The plant biomass and diversity of three steppe types in Inner Mongolia respond divergently to elevated N and P inputs.Our results indicate that regional differences in climate and soil substrate conditions may jointly contribute to the divergent responses of plant biomass and diversity to short-term N and P addition.Our analyses provide new insights into managing and protecting grassland ecosystems.Considering that the effects of nutrient addition on plant diversity and productivity may have increasing effects over time,studies on long-term in situ nutrient addition are necessary. | Ning Guo Mingyang Xie Zhao Fang Feng Jiao Xiaoyu Han | 2022 | Ecological Processes2022,11,1: | 1 |
| 14 | 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 |
| 15 | Design spherical particles of potassium peroxymonosulfate compound salt with high stability and good powder properties via an agglomeration-dissolution mechanism显示文摘With the outbreak of COVID-19,disinfection protection has become a necessary measure to prevent infection.As a new type of disinfectant,potassium peroxymonosulfate compound salt(PMS)has the advantages of good bactericidal effect,non-toxicity,high safety and stability.However,the current PMS products with irregular particle shapes lead to poor flowability,high hygroscopicity,poor stability of reactive oxygen species(ROS)and serious caking problems.In this work,an agglomeration-dissolution mechanism was designed to prepare spherical PMS particles with large size(>300μm)and high sphericity(up to 90%),effectively addressing the above problems.Shaping(dissolution and abrasion)is the key to improving sphericity,which is mainly controlled by the design of the heating mode,residence time and stirring rate.Compared with the irregular PMS particles,the large spherical particles present better flowability(angle of repose decreased by 35.80%,Carr's index decreased by 64.29%,Hausner's ratio decreased by 19.14%),lower hygroscopicity(decreased by 38.0%),lower caking ratio(decreased by 84.50%),and higher stability(the monthly loss of ROS was reduced by 61.68%).The agglomeration-dissolution mechanism demonstrates the crystallization,agglomeration,dissolution and abrasion process of inorganic salt crystals,providing an opportunity to prepare high-end inorganic crystal materials with high-quality morphologies. | Shanshan Feng Changyou Yu Shilin Guo Jinbo Ouyang Fei Yin Xiaodong Zhang Yongjian Zhang Mingyang Chen Dandan Han Junbo Gong Jingkang Wang | 2023 | Particuology2023,,9: | 0 |

| 17 | Nitrogen ion irradiation effect on enhancing photocatalytic performance of CdTe/ZnO heterostructures显示文摘To deal with the increasingly deteriorating environment problems, more and more harsh requirements are put forward for photocatalysis application. Building semiconductor heterostructures has been proven to be an efficient way to enhance photocatalytic performance. A kind of CdTe/ZnO heterostructures were synthesized by a hydrothermal and successive ionic layer absorption and reaction (SILAR) method and achieved obviously efficient photocatalytic performance. Moreover, after the N ion irradiation treatment, the photocatalytic activity was further enhanced, which can be ascribed to the introduction of oxygen vacancy defects. The photocatalytic performance enhancement mechanism by coupling constructing heterostructures and Ion irradiation are further studied to give us an overall understanding on ZnO nanowires. | Yazi WANG Wei LI Yimeng FENG Shasha LV Mingyang LI Zhengcao LI | 2018 | Frontiers of Materials Science2018,12,4: | 0 |
| 18 | Self-assembly of Gradient Copolymer Synthesized by Spontaneous Batch RAFT Emulsion Polymerization and Its Application on Encapsulating Ag Nanoparticles显示文摘The gradient copolymers of acrylic acid and trifluoroethyl methacrylate(coded as P(TFEMAgrad-AA)) were synthesized via reversible addition-fragmentation transfer(RAFT) emulsifier-free emulsion polymerization. The spontaneous batch feeding approach was used to control the gradient chain sequence. Transmission electron microscopy(TEM) analysis revealed that the P(TFEMA-grad-AA) can self-assemble to form spherical micelles, rodlike micelles or vesicles in selective solvents. Morphological transition of the P(TFEMA-grad-AA) micelles was sensitive to the water content of the dioxane/water mixed solvent. More interestingly, Ag nanoparticles(NPs) were encapsulated by the P(TFEMA-grad-AA) micelles during the selfassembly process. The gradient chain sequence made the Ag NPs easily enter the core of the micelles, even when P(TFEMA-grad-AA) had less hydrophobic fluoro-units and more hydrophilic units. TEM images with energy dispersive spectrometer indicated that the nanocomposite micelles consisted of a Ag NPs core and a gradient copolymer shell. | 秦超然 FENG Menran LUO Wen LIU Mingyang HAN Mei MA Shuai 王艺峰 | 2018 | Journal of Wuhan University of Technology(Materials Science)2018,33,4: | 0 |
| 19 | Activating and stabilizing the surface of anode for high-performing direct-ammonia solid oxide fuel cells显示文摘Ammonia has been recognized as a promising fuel for solid oxide fuel cells(SOFCs)because of its relatively high hydrogen content and high energy density.However,the effective catalysis of ammonia on the surface of state-of-the-art anode greatly hinders the further development of direct ammonia SOFCs.In this study,we report our findings of surface activating and stabilizing of a Ni-based cermet anode for highly efficient and durable operation on ammonia fuel,achieved by a surface coating of CeO_(2)−δnanoparticles(NPs).When incorporated into a Ni-yttria-stabilized zirconia(Ni-YSZ)anode-supported single cell,the coatings demonstrate an improved electrochemical reaction activity and stability,achieving a high peak power density of 0.941 W·cm^(−2)at 700℃,and a promising stability of~60 h(degradation rate of 0.127%h^(−1)at 0.5 A·cm−2),much better than those of cells with a bare anode(~0.673 W·cm^(−2)and degradation rate of 0.294%h−1 at 0.5 A·cm^(-2)).The catalytic NPs significantly enhance the reaction activity toward the decomposition of ammonia and oxidation of hydrogen,especially at low temperatures(<700℃),as confirmed by the detailed distribution of relaxation time(DRT)analyses of the impedance spectra of the cells on NH3 fuel. | Kang Xu Feng Zhu Mingyang Hou Canan Li Hua Zhang Yu Chen | 2023 | Nano Research2023,16,2: | 0 |
| 20 | A PD-L1-targeting chimeric switch receptor enhances efficacy of CAR-T cell for pleural and peritoneal metastasis显示文摘Pleural and peritoneal metastasis accompanied by malignant pleural effusion(MPE)or malignant ascites(MA)is frequent in patients with advanced solid tumors that originate from the lung,breast,gastrointestinal tract and ovary.Regional delivery of CAR-T cells represents a new strategy to control tumor dissemination in serous cavities.However,malignant effusions constitute an immune-suppressive environment that potentially induces CAR-T cell dysfunction.Here,we demonstrated that the anti-tumor cytotoxicity of conventional 2nd-generation CAR-T cells was significantly inhibited by both the cellular and non-cellular components of MPE/MA,which was primarily attributed to impaired CAR-T cell proliferation and cytokine production in MPE/MA environment.Interestingly,we found that PD-L1 was widely expressed on freshly-isolated MPE/MA cells.Based on this feature,a novel PD-L1-targeting chimeric switch receptor(PD-L1.BB CSR)was designed,which can bind to PD-L1,switching the inhibitory signal into an additional 4-1BB signal.When co-expressed with a 2nd-generation CAR,PD-L1.BB CSR-modified CAR-T cells displayed superior fitness and enhanced functions in both culture medium and MPE/MA environment,causing rapid and durable eradication of pleural and peritoneal metastatic tumors in xenograft models.Further investigations revealed elevated expressions of T-cell activation,proliferation,and cytotoxicity-related genes,and we confirmed that PD-L1 scFv and 4-1BB intracellular domain,the two important components of PD-L1.BB CSR,were both necessary for the functional improvements of CAR-T cells.Overall,our study shed light on the clinical application of PD-L1.BB CSR-modified dual-targeting CAR-T cells.Based on this study,a phase I clinical trial was initiated in patients with pleural or peritoneal metastasis(NCT04684459). | Qizhi Ma Xia He Benxia Zhang Fuchun Guo Xuejin Ou Qiyu Yang Pei Shu Yue Chen Kai Li Ge Gao Yajuan Zhu Diyuan Qin Jie Tang Xiaoyu Li Meng Jing Jian Zhao Zeming Mo Ning Liu Yao Zeng Kexun Zhou Mingyang Feng Weiting Liao Wanting Lei Qiu Li Dan Li Yongsheng Wang | 2022 | Signal Transduction and Targeted Therapy2022,7,12: | 0 |
