| 2 | An iron-dependent form of non-canonical ferroptosis induced by labile iron显示文摘Ferroptosis is a recently identified iron-dependent form of nonapoptotic cell death characterized by reactive oxygen species(ROS) generation and lipid peroxidation.Here,we report a novel iron-dependent form of ferroptosis induced by labile iron and investigate the mechanism underlying this process.We find that labile iron-induced ferroptosis is distinct from canonical ferroptosis and is linked to the mitochondrial pathway.Specifically,the mitochondrial calcium uniporter mediates the ferroptosis induced by labile iron.Interestingly,cells undergoing labile iron-induced ferroptosis exhibit cytoplasmic features of oncosis and nuclear features of apoptosis.Furthermore,labile iron-induced ferroptosis involves a unique set of genes.Finally,labile ironinduced ferroptosis was observed in liver subjected to acute iron overload in vivo.Our study reveals a novel form of ferroptosis that may be implicated in diseases caused by acute injury. | Yanmeng Li Qin Ouyang Wei Chen Ke Liu Bei Zhang Jingyi Yao Song Zhang Junying Ding Min Cong Anjian Xu | 2023 | Science China(Life Sciences)2023，66，3： | 1 |
| 3 | Stacking monolayers at will:A scalable device optimization strategy for two-dimensional semiconductors显示文摘In comparison to monolayer(1L),multilayer(ML)two-dimensional(2D)semiconducting transition metal dichalcogenides(TMDs)exhibit more application potential for electronic and optoelectronic devices due to their improved current carrying capability,higher mobility,and broader spectral response.However,the investigation of devices based on wafer-scale ML-TMDs is still restricted by the synthesis of uniform and high-quality ML films.In this work,we propose a strategy of stacking MoS_(2) monolayers via a vacuum transfer method,by which one could obtain wafer-scale high-quality MoS_(2) films with the desired number of layers at will.The optical characteristics of these stacked ML-MoS_(2) films(>2L)indicate a weak interlayer coupling.The stacked MLMoS_(2) phototransistors show improved optoelectrical performances and a broader spectral response(approximately 300-1,000 nm)than that of 1L-MoS_(2).Additionally,the dual-gate ML-MoS_(2) transistors enable enhanced electrostatic control over the stacked ML-MoS_(2) channel,and the 3L and 4L thicknesses exhibit the optimal device performances according to the turning point of the current on/off ratio and the subthreshold swing. | Xiaojiao Guo Honglei Chen Jihong Bian Fuyou Liao Jingyi Ma Simeng Zhang Xinzhi Zhang Junqiang Zhu Chen Luo Zijian Zhang Lingyi Zong Yin Xia Chuming Sheng Zihan Xu Saifei Gou Xinyu Wang Peng Gong Liwei Liu Xixi Jiang Zhenghua An Chunxiao Cong Zhijun Qiu Xing Wu Peng Zhou Xinyu Chen Ling Tong Wenzhong Bao | 2022 | Nano Research2022，15，7： | 0 |
| 4 | Antimicrobial resistance characteristics and phylogenetic relationships of pleuromutilin-resistant Enterococcus isolates from different environmental samples along a laying hen production chain显示文摘Antimicrobial resistance in the laying hen production industry has become a serious public health problem.The antimicrobial resistance and phylogenetic relationships of the common conditional pathogen Enterococcus along the laying hen production chain have not been systematically clarified.105 Enterococcus isolates were obtained from 115 environmental samples (air,dust,feces,fies,sewage,and soil) collected along the laying hen production chain (breeding chicken,chick,young chicken,and commercial laying hen).These Enterococcus isolates exhibited resistance to some clinically relevant antibiotics,such as tetracycline (92.4%),streptomycin (92.4%),and erythromycin (91.4%),and all strains had multidrug resistance phenotypes.Whole genome sequencing characterized 29 acquired antibiotic resistance genes (ARGs) that conferred resistance to 11 classes of antibiotics in 51pleuromutilin-resistant Enterococcus isolates,and lsa(E),which mediates resistance to pleuromutilins,always co-occurred with lnu(B).Alignments with the Mobile Genetic Elements database identified four transposons (Tn554,Tn558,Tn6261,and Tn6674) with several ARGs(erm(A),ant(9)-la,fex(A),and optrA) that mediated resistance to many clinically important antibiotics.Moreover,we identified two new transposons that carried ARGs in the Tn554 family designated as Tn7508 and Tn7492.A complementary approach based on conventional multi-locus sequence typing and whole genome single nucleotide polymorphism analysis showed that phylogenetically related pleuromutilin-resistant Enterococcus isolates were widely distributed in various environments on different production farms.Our results indicate that environmental contamination by antimicrobial-resistant Enterococcus requires greater attention,and they highlight the risk of pleuromutilin-resistant Enterococcus and ARGs disseminating along the laying hen production chain,thereby warranting effective disinfection. | Cong Lin Yuxuan Feng Xianjun Xie Haoyu Zhang Jie Wu Yixiao Zhu Jing Yu Jingyi Feng Wen Su Shanming Lai Anyun Zhang | 2024 | Journal of Environmental Sciences2024，，3： | 0 |
| 5 | Centurial Evolution of an Offshore Mud Deposition Area in the Changjiang (Yangtze) Estuary and Its Links to Environmental and Anthropogenic Activities显示文摘Large amounts of sediments originating from the Changjiang(Yangtze)River are deposited in the subaqueous delta and in the adjacent muddy area off the mouth and on the inner shelf of the East China Sea.The terrestrial sediments deposited in these areas not only contain information about the composition and environment of the source area,but they also record changes in anthropogenic activities.A sediment piston core(CJ0702)was extracted from the Changjiang subaqueous depocenter(31.00°N,122.67°E)in a water depth of 22.0 m.The core was subsampled at 1–2 cm intervals and analyzed for grain size,clay mineralogy,and major element geochemistry.Results indicate a relatively high sediment accumulation rate of approximately 3.11 cm yr−1.These parameters exhibited only minor cyclical fluctuations in the core,which resulted from many factors.During the past 120 years,the Changjiang River-derived sediment is the primary source of sediment in the offshore mud area without evidence for the Yellow River-derived sediment increasing.After the trunk stream shifted from the North Branch to South Branch,the variations of proxies are controlled by the periodic fluctuation possibly linked to El Niño-Southern Oscillation(ENSO)and the Pacific Decadal Oscillation(PDO).In addition,anthropogenic heavy metal concentrations can be divided into three stages,which coincide well with economic development and environmental protection policies. | CONG Jingyi HU Gang JONELL Tara N YUAN Zhongpeng KONG Xianghuai ZHANG Yong WANG Yonghong | 2020 | Journal of Ocean University of China2020，19，4： | 0 |
| 6 | Encrypted optical fiber tag based on encoded fiber Bragg grating array显示文摘Optical fibers are typically used in telecommunications services for data transmission,where the use of fiber tags is essential to distinguish between the different transmission fibers or channels and thus ensure the working functionality of the communication system.Traditional physical entity marking methods for fiber labeling are bulky,easily confused,and,most importantly,the label information can be accessed easily by all potential users.This work proposes an encrypted optical fiber tag based on an encoded fiber Bragg grating(FBG)array that is fabricated using a point-by-point femtosecond laser pulse chain inscription method.Gratings with different resonant wavelengths and reflectivities are realized by adjusting the grating period and the refractive index modulations.It is demonstrated that a binary data sequence carried by a fiber tag can be inscribed into the fiber core in the form of an FBG array,and the tag data can be encrypted through appropriate design of the spatial distributions of the FBGs with various reflection wavelengths and reflectivities.The proposed fiber tag technology can be used for applications in port identification,encrypted data storage,and transmission in fiber networks. | Zhihao Cai Bozhe Li Zhiyong Bai Dejun Liu Kaiming Yang Bonan Liu Cong Zhao Mengqiang Zou Jie Zhou Shangben Jiang Jingyi Huang Li Liu Xuming Zhang Junle Qu Yiping Wang Changrui Liao | 2023 | International Journal of Extreme Manufacturing2023，5，3： | 0 |
| 7 | Deletion of all three MAP kinase genes results in severe defects in stress responses and pathogenesis in Fusarium graminearum显示文摘Mitogen-activated protein kinase(MAPK)cascades are activated by external stimuli and convert signals to cellular changes.Individual MAPKs have been characterized in a number of plant pathogenic fungi for their roles in pathogenesis and responses to biotic or abiotic stresses.However,mutants deleted of all the MAPK genes have not been reported in filamentous fungi.To determine the MAPK-less effects in a fungal pathogen,in this study we generated and characterized mutants deleted of all three MAPK genes in the wheat scab fungus Fusarium graminearum.The Gpmk1 mgv1 Fghog1 triple mutants had severe growth defects and was non-pathogenic.It was defective in infection cushion formation and DON production.Conidiation was reduced in the triple mutant,which often produced elongated conidia with more septa than the wild-type conidia.The triple mutant was blocked in sexual reproduction due to the loss of female fertility.Lack of any MAPKs resulted in an increased sensitivity to various abiotic stress including cell wall,osmotic,oxidative stresses,and phytoalexins,which are likely related to the defects of the triple mutant in environmental adaptation and plant infection.The triple mutant also had increased sensitivity to the biocontrol bacterium Bacillus velezensis and fungus Clonostachys rosea.In co-incubation assays with B.velezensis,the Gpmk1 mgv1 Fghog1 mutant had more severe growth limitation than the wild type and was defective in conidium germination and germ tube growth.In confrontation assays,the triple mutant was defective in defending against mycoparasitic activities of C.rosea and the latter could grow over the mutant but not wild-type F.graminearum.RNA-seq and metabolomics analyses showed that the MAPK triple mutant was altered in the expression of many ATP-binding cassette(ABC)and major facilitator superfamily(MFS)transporter genes and the accumulation of metabolites related to arachidonic acid,linoleic acid,and alpha-linolenic acid metabolisms.Overall,as the first study on mutants deleted of all three MAPKs in fungal pathogens,our results showed that although MAPKs are not essential for growth and asexual reproduction,the Gpmk1 mgv1 Fghog1 triple mutant was blocked in plant infection and sexual reproductions.It also had severe defects in responses to various abiotic stresses and bacterial-or fungal-fungal interactions. | Jingyi Ren Yuhan Zhang Yuhua Wang Chengliang Li Zhuyun Bian Xue Zhang Huiquan Liu Jin-Rong Xu Cong Jiang | 2022 | Stress Biology2022，2，1： | 0 |

| 9 | Exploring the abundance and influencing factors of antimicrobial resistance genes in manure plasmidome from swine farms显示文摘Plasmids play a critical role in the dissemination of antimicrobial resistance genes(ARGs),however,a systematical understanding of ARGs originated from plasmids in swine production is currently lacking.Herein,quantitative polymerase chain reaction was applied to determine the prevalence of ten ARGs and the class1 integron gene intI1 of plasmid source in swinemanure from 44 farms in Sichuan,Hubei and Hebei provinces,China.All assayed ARGs were observed in plasmid DNA samples,and the average absolute abundance of aac(6’)-Ib-cr,blaNDM,blaCTX-M,optrA,ermB,floR,mcr-1,qnrS,tetM,sul1 and intI1 were 7.09,2.90,4.67,6.62,7.55,7.14,4.08,4.85,7.16,7.11 and 8.07 of 10 log copies/gram,respectively.IntI1 showed a high correlation(r>0.8,P<0.01)with the abundance of aac(6’)-Ib-cr and sul1 in swine manure.Moreover,the farm scale(i.e.,herd population)and geographical location were not found to be critical factors influencing the absolute abundance of ARGs of plasmid DNA in swine farms.However,the concentrations of florfenicol,Cu,Zn,Fe,total phosphorus(TP)and total potassium(TK)demonstrated a significant correlation with the abundance of several ARGs.Particularly,Cu and Zn had high correlations with optrA and blaCTX-M,respectively.Our results demonstrated that antibiotics,heavy metals and environmental nutrients are likely jointly contributing to the long-term persistence of ARGs in swine production.This study provides insights into the abundance and influencing factors of ARGs from swine manure,which is of significance for assessing and reducing the public health risks in livestock production. | Zunfang Tu Junrui Shui Jinxin Liu Hongmei Tuo Haoyu Zhang Cong Lin Jingyi Feng Yuxuan Feng Wen Su Anyun Zhang | 2023 | Journal of Environmental Sciences2023，，2： | 0 |
| 10 | Clay minerals and elemental composition of sediments on different sedimentary units in the northern East China Sea shelf:provenance tracing and genetic mechanism analysis显示文摘The composition,provenance,and genetic mechanism of sediment on different sedimentary units of the East China Sea(ECS)shelf are essential for understanding the depositional dynamics environment in the ECS.The sediments in the northern ECS shelf are distributed in a ring-shaped distribution centered on the southwestern Cheju Island Mud.From the inside to the outside,the grain size goes from fine to coarse.Aside from the“grain size effect”,hydrodynamic sorting and mineral composition are important restrictions on the content of rare earth elements(REEs).Based on the grain size,REEs,and clay mineral composition of 300 surface sediments,as well as the sedimentary genesis,the northern ECS shelf is divided into three geochemical zones:southwestern Cheju Island Mud Area(ZoneⅠ),Changjiang Shoal Sand Ridges(ZoneⅡ-1),Sand Ridges of the East China Sea shelf(ZoneⅡ-2).The northern ECS shelf is mostly impacted by Chinese mainland rivers(the Changjiang River and Huanghe River),and the provenance and transport mechanism of sediments of different grain sizes is diverse.The bulk sediments come primarily from the Changjiang River,with some material from the Huanghe River carried by the Yellow Sea Coastal Current and the North Jiangsu Coastal Current,and less from Korean rivers.Among them,surface sediments in the southwestern Cheju Island Mud Area(ZoneⅠ)come mostly from the Changjiang River and partly from the Huanghe River.It was formed by the counterclockwise rotating cold eddies in the northern ECS shelf,which caused the sedimentation and accumulation of the fine-grained sediments of the Changjiang River and the Huanghe River.The Changjiang Shoal Sand Ridges(ZoneⅡ-1)were developed during the early-middle Holocene sea-level highstand.It is the modern tidal sand ridge sediment formed by intense hydrodynamic action under the influence of the Yellow Sea Coastal Current,North Jiangsu Coastal Current,and Changjiang Diluted Water.The surface sediments mainly originate from the Changjiang River and Huanghe River,with the Changjiang River dominating,and the Korean River(Hanjiang River)influencing just a few stations.Sand Ridges of the East China Sea shelf(ZoneⅡ-2)are the relict sediments of the paleo-Changjiang River created by sea invasion at the end of the Last Deglaciation in the Epipleistocene.The clay mineral composition of the surface sediments in the study area is just dominated by the Changjiang River,with the North Jiangsu Coastal Current and the Changjiang Diluted Water as the main transporting currents. | Xiaoyan Xu Yong Zhang Yanguang Dou Jingyi Cong Beibei Mi Xiaohui Chen Xia Li Chengfen Xu Yongyu Ye | 2023 | Acta Oceanologica Sinica2023，42，11： | 0 |
