1Safety profile of two-dimensional Pd nanosheets for photothermal therapy and photoacoustic imaging显示文摘二维(2D ) nanosheets 在 biomedicines 的领域里与大潜力作为 nanomaterial 的一个重要的类出现了,特别地在癌症 theranostics。然而,由于综合的有效方法的缺乏有控制尺寸的一致 2D nanomaterials, 2D nanomaterials 的尺寸依赖者简历行为的系统的评估很少被报导。就我们的知识而言,我们是第一报导对他们的简历行为的 2D nanomaterials 的尺寸的影响的系统的评估。有从 5 ~ 80 nm 的直径的 2D Pd nanosheets 被综合并且在房间和动物模型测试了估计他们基因表示介绍的尺寸依赖者 bioapplication, biodistribution,消除,毒性,和 genomic。我们的结果证明尺寸显著地影响 Pd nanosheets 的生物行为,包括他们的 photothermal 和 photoacoustic 效果, pharmacokinetics,和毒性。比作大尺寸的 Pd nanosheets,更展出的小尺寸的 Pd nanosheets 在 ultralow 之上预付 photoacoustic 成像和 photothermal 效果激光照耀。而且,在 vivo,结果显示 5-nm Pd nanosheets 与更长的血半衰期逃离网状内皮组织的系统并且能被肾的排泄清除,当时有更大的尺寸的 Pd nanosheets 主要在肝和怒气积累。30-nm Pd nanosheets 展出了最高的肿瘤累积。尽管 Pd nanosheets 没在细胞的水平引起任何可估计的毒性,我们在怒气在肝和发炎观察了细微类脂化合物累积。Genomic 基因表达式分析证明 80-nm Pd nanosheets 与更细胞的部件交往了并且在肝影响了更生物的进程,作为与 5-nm Pd nanosheets 相比。我们相信这个工作将作为 nanomedicines 提供珍贵信息和卓见进 2D Pd nanosheets 的临床的申请。Mei Chen Shuzhen Chen Chengyong He Shiguang Mo Xiaoyong Wang Gang Liu Nanfeng Zheng 2017Nano Research2017,10,4:5
2Drilling Force and Temperature of Bone under Dry and Physiological Drilling Conditions显示文摘Many researches on drilling force and temperature have been done with the aim to reduce the labour intensiveness of surgery, avoid unnecessary damage and improve drilling quality. However, there has not been a systematic study of mid- and high-speed drilling under dry and physiological conditions(injection of saline). Furthermore, there is no consensus on optimal drilling parameters. To study these parameters under dry and physiological drilling conditions, pig humerus bones are drilled with medical twist drills operated using a wide range of drilling speeds and feed rates. Drilling force and temperature are measured using a YDZ-II01 W dynamometer and a NEC TVS-500 EX thermal infrared imager, respectively, to evaluate internal bone damage. To evaluate drilling quality, bone debris and hole morphology are observed by SEM(scanning electron microscopy). Changes in drilling force and temperature give similar results during drilling such that the value of each parameter peaks just before the drill penetrates through the osteon of the compact bone into the trabeculae of the spongy bone. Drilling temperatures under physiological conditions are much lower than those observed under dry conditions, while a larger drilling force occurs under physiological conditions than dry conditions. Drilling speed and feed rate have a significant influence on drilling force, temperature, bone debris and hole morphology. The investigation of the effect of drilling force and temperature on internal bone damage reveals that a drilling speed of 4500 r/min and a feed rate of 50 mm/min are recommended for bone drilling under physiological conditions. Drilling quality peaks under these optimal parameter conditions. This paper proposes the optimal drilling parameters under mid- and high-speed surgical drilling, considering internal bone damage and drilling quality, which can be looked as a reference for surgeons performing orthopedic operations.XU Linlin WANG Chengyong JIANG Min HE Huiyu SONG Yuexian CHEN Hanyuan SHEN Jingnan ZHANG Jiayong 2014Chinese Journal of Mechanical Engineering2014,27,6:3
3Comparison of developmental toxicity of different surface modified CdSe/ZnS QDs in zebrafish embryos显示文摘Quantum dots(QDs)are new types of nanomaterials.Few studies have focused on the effect of different surface modified QDs on embryonic development.Herein,we compared the in vivo toxicity of Cd Se/Zn S QDs with carboxyl(-COOH)and amino(-NH 2)modification using zebrafish embryos.After exposure,the two Cd Se/Zn S QDs decreased the survival rate,hatching rate,and embryo movement of zebrafish.Moreover,we found QDs attached to the embryo membrane before hatching and the eyes,yolk and heart after hatching.The attached amount of carboxyl QDs was more.Consistently,the Cd content in embryos and larvae was higher in carboxyl QD-treatment.We further observed that the two QDs caused zebrafish pericardial edema and cardiac dysfunction.In line with it,both carboxyl and amino QDs upregulated the transcription levels of cardiac development-related genes,and the levels were higher in carboxyl QD-treated groups.Furthermore,the chelator of Cd^2+diethylene triamine pentacetate acid could partially rescued the developmental toxicity caused by the two types of QDs suggesting that both the nature of QDs and the release of Cd^2+contribute to the developmental toxicity.In conclusion,the two Cd Se/ZnS QDs have developmental toxicity and affect the cardiac development,and the carboxyl QDs is more toxic possibly due to the higher affinity and more release to embryos and larvae.Our study provides new knowledge that the surface functional modification of QDs is critical on the development on aquatic species,which is beneficial to develop and applicate QDs more safely and environmentfriendly.Naying Zheng Jinhui Yan Wang Qian Chao Song Zhenghong Zuo Chengyong He 2021Journal of Environmental Sciences2021,33,2:3
4An iridium(Ⅲ)-palladium(Ⅱ) metal-organic cage for efficient mitochondria-targeted photodynamic therapy显示文摘An Ir8 Pd4-heteronuclear metal-organic cage(MOC-51)was assembled from bipodal metalloligand[Ir(ppy)2(qpy)(BF4)](qpy=4,4′:2′,2″:4″,4′′′-quaterpyridine;ppy-2-phenylpridine)with Pd(Ⅱ)salt.The cubic barrel shaped MOC shows one-photon and two-photon excited deep-red emission,as well as large singlet oxygen quantum yields under visible light irradiation,therefore exhibiting great potentials in organelles-targeted cell imaging and photodynamic therapy(PDT).Compared with the Ir(Ⅲ)metalloligand,the Ir8 Pd4-MOC showed less dark toxicity and higher mitochondria-targeting efficiency.The localization in mitochondria overco mes the limitation of short lifetime and diffusion distance of ROS in cell,thus improved PDT effect can be obtained in low light dose usage of the MOC.This study presents the first case of Ir-based metal-organic cages for bio-applications in successful integration of imaging diagnosis and photodynamic therapy.Chaojie Li Yaping Wang Yulin Lu Jing Guo Chengyi Zhu Haozhe He Xiaohui Duan Mei Pan Chengyong Su 2020Chinese Chemical Letters2020,31,5:1
5Incidence,genomic diversity,and evolution of strawberry mottle virus in China显示文摘Strawberry mottle virus(SMoV)is one of the most common viruses infecting strawberries,causing losses to fruit yield and quality.In this study,165 strawberry leaf samples were collected from six provinces of China,46 of which tested positive for SMoV.The complete genome sequences of 11 SMoV isolates were obtained from Liaoning(DGHY3,DGHY16-2,DGHY17,DGHY20-2,DGHY21,DGHY26-2),Shandong(SDHY1,SDHY5,SDHY31-2,SDHY33-2),and Beijing(BJMX7).The RNA1 and RNA2 nucleotide identities between the 11 Chinese isolates were 95.4-99.3%and 96.3-99.6%,respectively,and they shared 78.4-96.6%and 84.8-93.5%identities with the available SMoV isolates in GenBank.Recombination analysis revealed that Chinese isolate SDHY33-2 and Canadian isolates Ontario and Simcoe were recombinants,and recombination events frequently occurred in the 3’UTR of SMoV.Phylogenetic analysis showed that in an RNA1 tree,most Chinese isolates clustered into the same group while isolate DGHY17 clustered into another group together with Czech isolate C and three Canadian isolates.In an RNA2 tree,all Chinese isolates clustered into a single group.The phylogenetic analysis based on nucleotide sequences was consistent with the results based on coat protein(CP)and RNA-dependent RNA polymerase(RdRp).Further evolutionary analysis indicated that negative selection drives SMoV evolution,and gene flow plays a major role in genetic differentiation.Additionally,reassortment and recombination also influence the evolution of SMoV.To our knowledge,this is the first report of the complete genome of SMoV isolates from China and a detailed analysis of the SMoV population structure.LINGJIAO FAN CHENGYONG HE MENGMENG WU DEHANG GAO ZHENFEI DONG SHENGFAN HOU ZEKUN FENG HONGQING WANG 2021BIOCELL2021,45,4:1

7Mepanipyrim induces cardiotoxicity of zebrafish(Danio rerio) larvae via promoting AhR-regulated COX expression pathway显示文摘The wide use of pesticides has seriously threatened human health and the survival of beneficial organisms. The fungicide mepanipyrim is widely used in viticulture practices. Studies of mepanipyrim-induced toxicity in organisms are still scarce, especially studies on cardiotoxicity. In this study, we aimed to investigate mepanipyrim-induced cardiotoxicity in zebrafish(Danio rerio) larvae. We found that mepanipyrim could induce cardiotoxicity by altering the heart rate and cardiomyocyte diameter of larvae. Meanwhile, RNA sequencing and RT-qPCR data indicated that mepanipyrim exposure could dramatically alter the m RNA expression of calcium signaling pathway-, cardiac muscle contraction-, and oxidative respiratory chain-related genes. Interestingly, by the CALUX cell bioassay, we found that most cytochrome c oxidase(COX) family genes exhibited potential AhR-regulated activity, suggesting that mepanipyrim induced cardiotoxicity via a novel AhR-regulated manner in larvae.Additionally, the AhR antagonist CH_(2)23191 could effectively prevent mepanipyrim-induced cardiotoxicity in zebrafish larvae. In conclusion, the AhR agonist mepanipyrim could induce cardiotoxicity in a novel unreported AhR-regulated manner, which could specifically affect the expression of COX family genes involved in the mitochondrial oxidative respiratory chain. Our data will help explain the toxic effects of mepanipyrim on organisms and provide new insight into the AhR agonistic activity pesticide-induced cardiotoxicity.Chao Shen Jing He Kongyang Zhu Naying Zheng Yue Yu Chengyong He Chunyan Yang Zhenghong Zuo 2023Journal of Environmental Sciences2023,,3:0
8Orbitally driven giant thermal conductance associated with abnormal strain dependence in hydrogenated graphene-like borophene显示文摘Heat energy in solids is carried by phonons and electrons.However,in most two-dimensional(2D)materials,the contribution from electrons to total thermal conduction is much lower than that for phonons.In this work,through first-principles calculations combined with non-equilibrium Green’s function theory,we studied electron and phonon thermal conductance in recently synthesized 2D hydrogen boride.The hexagonal boron network with bridging hydrogen atoms is suggested to exhibit comparable lattice thermal conductance(4.07 nWK−1 nm−2)as graphene(4.1 nWK−1 nm−2),and similar electron thermal conductance(3.6 nWK−1 nm−2),which is almost ten times that of graphene.As a result,total thermal conductance of 2D hydrogen boride is about two-fold of graphene,being the highest value in all known 2D materials.Moreover,tensile strain along the armchair direction leads to an increase in carrier density,significantly increasing electron thermal conductance.The increase in electron thermal conductance offsets the reduction in phonon thermal conductance,contributing to an abnormal increase in thermal conductance.We demonstrate that the high electron density governs extraordinarily high thermal conductance in 2D hydrogen boride,distinctive among 2D materials.Jia He Dengfeng Li Yan Ying Chunbao Feng Junjie He Chengyong Zhong Hangbo Zhou Ping Zhou Gang Zhang 2019npj Computational Materials2019,,1:0
9Black phosphorus quantum dots induce myocardial inflammatory responses and metabolic disorders in mice显示文摘As an ultrasmall derivative of black phosphorus(BP)sheets,BP quantum dots(BP-QDs)have been effectively used in many fields.Currently,information on the cardiotoxicity induced by BP-QDs remains limited.We aimed to evaluate BP-QD-induced cardiac toxicity in mice.Histopathological examination of heart tissue sections was performed.Transcriptome sequencing,real-time quantitative PCR(RT–qPCR),western blotting,and enzyme-linked immunosorbent assay(ELISA)assays were used to detect the m RNA and/or protein expression of proinfammatory cytokines,nuclear factor kappa B(NF-κB),phosphatidylinositol3 kinase-protein kinase B(PI3K-AKT),peroxisome proliferator-activated receptor gamma(PPARγ),and glucose/lipid metabolism pathway-related genes.We found that heart weight and heart/body weight index(HBI)were significantly reduced in mice after intragastric administration of 0.1 or 1 mg/kg BP-QDs for 28 days.In addition,obvious infammatory cell infiltration and increased cardiomyocyte diameter were observed in the BP-QD-treated groups.Altered expression of proinfammatory cytokines and genes related to the NF-κB signaling pathway further confirmed that BP-QD exposure induced infammatory responses.In addition,BP-QD treatment also affected the PI3K-AKT,PPARγ,thermogenesis,oxidative phosphorylation,and cardiac muscle contraction signaling pathways.The expression of genes related to glucose/lipid metabolism signaling pathways was dramatically affected by BP-QD exposure,and the effect was primarily mediated by the PPAR signaling pathway.Our study provides new insights into the toxicity of BP-QDs to human health.Chao Shen Xiaoyan Ding Jinpeng Ruan Fengkai Ruan Weiping Hu Jiyi Huang Chengyong He Yi Yu Zhenghong Zuo 2024Journal of Environmental Sciences2024,,3:0

11Tributyltin causes generational neurodevelopmental toxicity and the protective effect of folic acid in zebrafish显示文摘Tributyltin(TBT),a common organotin environmental pollutant,may pose a threat to human development during critical early-life periods.We aimed to assess the neurodevelopmental intergenerational toxicity of early-life exposure to TBT and the protective effect of DNA methyl donor folic acid(FA).Specifically,after early-life exposure(1–21 days postfertilization,dpf)to TBT(0,1,10 and 100 ng/L),zebrafish(Danio rerio)were cultured in clean medium until sexual maturity.The exposed females were mated with unexposed males to produce embryos(F1).The F1 generation were cultured(4–120 hours post-fertilization,hpf)with and without 1 mmol/L FA.The neurotoxic effects of early-life TBT exposure for zebrafish and their offspring(F1)were significantly enhanced anxiety and reduced aggression,decreased gene expression of DNA methyltransferase in the brain and increased serotonin levels in the body.Moreover,the intergenerational neurodevelopmental toxicity,as manifested in the F1 generation,was attenuated by FA supplementation.In summary,early-life TBT exposure led to intergenerational neurodevelopmental deficits in zebrafish,and DNA methyl donors had a protective effect on F1 neurodevelopment,which can inform the prevention and treatment of intergenerational neurotoxicity due to organotin pollutants.Haoxing Cai Naying Zheng Chen Tang Yuxuan Zhang Zhenghong Zuo Chengyong He 2024Journal of Environmental Sciences2024,,3:0
12Mepanipyrim induces visual developmental toxicity and vision-guided behavioral alteration in zebrafish larvae显示文摘Mepanipyrim,an anilinopyrimidine fungicide,has been extensively used to prevent fungal diseases in fruit culture.Currently,research on mepanipyrim-induced toxicity in organisms is still very scarce,especially visual developmental toxicity.Here,zebrafish larvae were employed to investigate mepanipyrim-induced visual developmental toxicity.Intense light andmonochromatic light stimuli-evoked escape experiments were used to investigate vision-guided behaviors.Meanwhile,transcriptomic sequencing and real-time quantitative PCR assays were applied to assess the potential mechanisms of mepanipyrim-induced visual developmental toxicity and vision-guided behavioral alteration.Our results showed that mepanipyrim exposure could induce retinal impairment and vision-guided behavioral alteration in larval zebrafish.In addition,the grk1b gene of the phototransduction signaling pathway was found to be a potential aryl hydrocarbon receptor(AhR)-regulated gene.Mepanipyrim-induced visual developmental toxicity was potentially related to the AhR signaling pathway.Furthermore,mepanipyrim-induced behavioral alteration was guided by the visual function,and the effects of mepanipyrim on long and middle wavelength light-sensitive opsins may be the main cause of vision-guided behavioral alteration.Our results provide insights into understanding the relationship between visual development and vision-guided behaviors induced by mepanipyrim exposure.Chao Shen Yimei Cai Jialing Li Chengyong He Zhenghong Zuo 2023Journal of Environmental Sciences2023,,2:0
