| 1 | Effects of dietary supplementation of probiotic,Clostridium butyricum,on growth performance,immune response,intestinal barrier function,and digestive enzyme activity in broiler chickens challenged with Escherichia coli K88显示文摘Background:Colibacillosis caused by enterotoxigenic Escherichia coli(E.coli) results in economic losses in the poultry industry.Antibiotics are usually used to control colibacillosis,however,E.coli has varying degrees of resistance to different antibiotics.Therefore the use of probiotics is becoming accepted as an alternative to antibiotics.In this study,we evaluated the effects of Clostridium butyricum(C.butyricum) on growth performance,immune response,intestinal barrier function,and digestive enzyme activity in broiler chickens challenged with Escherichia coli(E.coif) K88.Methods:The chickens were randomly divided into four treatment groups for 28 days.Negative control treatment(NC) consisted of birds fed a basal diet without E.coli K88 challenge and positive control treatment(PC) consisted of birds fed a basal diet and challenged with E.coli K88.C.butyricum probiotic treatment(CB) consisted of birds fed a diet containing 2×10~7 cfu C butyricum/kg of diet and challenged with E.coli K88.Colistin sulfate antibiotic treatment(CS)consisted of birds fed a diet containing 20 mg colistin sulfate/kg of diet and challenged with E.coli K88.Results:The body weight(BW) and average day gain(ADG) in the broilers of CB group were higher(P< 0.05) than the broilers in the PC group overall except the ADG in the 14-21 d post-challenge.The birds in CB treatment had higher(P < 0.05) concentration of tumor necrosis factor-α(TNF-α) at 3 and 7 d post-challenge,and higher(P < 0.05)concentration of interleukin-4(IL-4) at 14 d post-challenge than those in the PC treatment group.The concentration of serum endotoxin in CB birds was lower(P<0.05) at 21 d post-challenge,and the concentrations of serum diamine oxidase in CB birds were lower(P < 0.05) at 14 and 21 d post-challenge than in PC birds.Birds in CB treatment group had higher(P< 0.05) jejunum villi height than those in PC,NC,or CS treatment at 7,14,and 21 d post-challenge.In comparison to PC birds,the CB birds had lower(P < 0.05) jejunum crypt depth during the whole experiment.The birds in CB or CS treatment group had higher(P < 0.05) activities of amylase and protease at 3,7,and 14 d post-challenge,and higher(P< 0.05) activity of lipase at 3,7 d post-challenge than PC birds.Conclusions:In all,these results indicate that dietary supplementation with C.butyricum promotes immune response,improves intestinal barrier function,and digestive enzyme activities in broiler chickens challenged with E.coli K88.There is no significant difference between the C.butyricum probiotic treatment and the colistin sulfate antibiotic treatment.Therefore,the C.butyricum probiotic may be an alternative to antibiotic for broiler chickens. | Ling Zhang Lingling Zhang Xiu'an Zhan Xinfu Zeng Lin Zhou Guangtian Cao An'guo Chen Caimei Yang | 2016 | Journal of Animal Science and Biotechnology2016,7,1: | 43 |
| 2 | Efficient elimination of multidrug-resistant bacteria using copper sulfide nanozymes anchored to graphene oxide nanosheets显示文摘Antibacterial nanomaterials have attracted growing interest for bacterial infection therapy.However,most nanomaterials eliminate bacteria either physically or chemically,which hampers their efficacy when dealing with multidrug-resistant bacteria.To overcome this,we integrated copper sulfide(CuS)nanoparticles with active graphene oxide nanosheets(GO NSs)to synthesize a superior nanocomposite(CuS/GO NC)that acts both physically and chemically on the bacteria.CuS/GO NC was produced using a facile hydrothermal method,whereby the CuS nanoparticles grew and were uniformly dispersed on the GO NSs in situ.We found that the CuS/GO NC possesses a unique needle-like morphology that physically damages the bacterial cell membrane.CuS/GO NC also exhibits high oxidase-and peroxidase-like activity,ensuring efficient generation of the reactive oxygen species•OH from H2O2,which kills bacteria chemically.These features endow the CuS/GO NC with excellent antibacterial capabilities to kill multidrug-resistant bacteria such as methicillin-resistant Staphylococcus aureus(MRSA)with only a single dose.Additionally,it was found that the CuS/GO NC accelerated the healing of infected wounds in vivo owing to its good biocompatibility as well as facilitation of cell migration and collagen secretion.This study provides a new strategy to combine the physical and chemical antibacterial modes of nanomaterials to develop more effective therapies to combat multidrug-resistant bacterial infections. | Wanshun Wang Binglin Li Huili Yang Zefeng Lin Lingling Chen Zhan Li Jiayuan Ge Tao Zhang Hong Xia Lihua Li Yao Lu | 2020 | Nano Research2020,13,8: | 8 |
| 3 | Effect of heat treatment on the microstructure and mechanical properties of AZ80M magnesium alloy fabricated by wire arc additive manufacturing显示文摘To maximize the benefits of wire arc additive manufacturing(WAAM)processes,the effect of post-deposition heat treatment on the microstructure and mechanical properties of WAAM AZ80M magnesium(Mg)alloy was investigated.Three different heat treatment procedures(T4,T5 and T6)were performed.According to the results,after T4 heat treatment,the microsegregation of alloying elements was improved with the eutectic structure dissolved.Samples after T5 heat treatment inherited the net-like distribution of secondary phases similar to the as-deposited sample,where the eutectic structure covering the interdendritic regions and theβ-phase precipitated around the eutectic structure.After T6 heat treatment,the tinyβ-phases re-precipitated from the matrix and distributed in inner and outer of the grains.The hardness distribution of the samples went through T4 and T6 heat treatment was more uniform in comparison to that of T5 heat treated samples.The tensile test showed that the T6 heat treatment improved the strength and ductility,and the anisotropy between horizontal and vertical can be eliminated.Moreover,T4 treated samples exhibited highest ductility. | Yangyang Guo Gaofeng Quan Mert Celikin Lingbao Ren Yuhang Zhan Lingling Fan Houhong Pan | 2022 | Journal of Magnesium and Alloys2022,10,7: | 5 |
| 4 | Security Constrained Decentralized Peer-to-Peer Transactive Energy Trading in Distribution Systems显示文摘Peer-to-peer(P2P)transactive energy trading offers a promising solution for facilitating the efficient and secure operation of a distribution system consisting of multiple prosumers.One critical but challenging task is how to avoid system network constraints to be violated for the distribution system integrated with extensive P2P transactive energy trades.This paper proposes a security constrained decentralized P2P transactive energy trading framework,which allows direct energy trades among neighboring prosumers in the distribution system with enhanced system efficiency and security in which no conventional intermediary is required.The P2P transactive energy trading problem is formulated based on the Nash Bargaining theory and decomposed into two subproblems,i.e.,an OPF problem(P1)and a payment bargaining problem(P2).A distributed optimization method based on the alternating direction method of multiplier(ADMM)is adopted as a privacy-preserving solution to the formulated security constrained P2P transactive energy trading model with ensured accuracy.Extensive case studies based on a modified 33-bus distribution system are presented to validate the effectiveness of the proposed security constrained decentralized P2P transactive energy trading framework in terms of efficiency improvement,loss reduction,and voltage security enhancement. | Lingling Wang Quan Zhou Zhan Xiong Zean Zhu Chuanwen Jiang Runnan Xu Zuyi Li | 2022 | CSEE Journal of Power and Energy Systems2022,8,1: | 2 |

| 9 | Ball-milling Synthesis of Single-atom Cu Anchored on N-Doped Carbon for Mimicking Peroxidase显示文摘Nanozymes have shown great potential for life sciences owing to their distinct advantages,such as low cost and high stability,compared with natural enzymes.Despite significant progress,state-of-art nanozymes commonly suffer from relatively low specific activities.Herein,we propose a promising to address this issue by creating single-atom nanozymes.A ball-milling-assisted strategy has been developed to induce the transformation of Cu species from bulk to single atoms.The highly-simplified steps allow a large-scale synthesis,that over 4.2 g of single-atom Cu-N doped carbon nanozymes can be achieved in one pot.It exhibits a remarkably improved peroxidase-like activity and stability compared with N doped C anchored Cu nanoparticles.Further experimental firmly reveals the crucial role of the single-atom Cu site that can generate more active·OH species for boosting the catalytic process. | XU Henan ZHANG Lingling WANG Huilin ZHANG Shaopeng LI Wei WANG Xiao SONG Shuyan WANG Daguang SHI Zhan | 2023 | Chemical Research in Chinese Universities2023,39,6: | 0 |
| 10 | Predicting recurrence in osteosarcoma via a quantitative histological image classifier derived from tumour nuclear morphological features显示文摘Recurrence is the key factor affecting the prognosis of osteosarcoma.Currently,there is a lack of clinically useful tools to predict osteosarcoma recurrence.The application of pathological images for artificial intelligence‐assisted accurate prediction of tumour out-comes is increasing.Thus,the present study constructed a quantitative histological image classifier with tumour nuclear features to predict osteosarcoma outcomes using haema-toxylin and eosin(H&E)‐stained whole‐slide images(WSIs)from 150 osteosarcoma patients.We first segmented eight distinct tissues in osteosarcoma H&E‐stained WSIs,with an average accuracy of 90.63%on the testing set.The tumour areas were auto-matically and accurately acquired,facilitating the tumour cell nuclear feature extraction process.Based on six selected tumour nuclear features,we developed an osteosarcoma histological image classifier(OSHIC)to predict the recurrence and survival of osteo-sarcoma following standard treatment.The quantitative OSHIC derived from tumour nuclear features independently predicted the recurrence and survival of osteosarcoma patients,thereby contributing to precision oncology.Moreover,we developed a fully automated workflow to extract quantitative image features,evaluate the diagnostic values of feature sets and build classifiers to predict osteosarcoma outcomes.Thus,the present study provides a novel tool for predicting osteosarcoma outcomes,which has a broad application prospect in clinical practice. | Zhan Wang Haoda Lu Yan Wu Shihong Ren Diarra mohamed Diaty Yanbiao Fu Yi Zou Lingling Zhang Zenan Wang Fangqian Wang Shu Li Xinmi Huo Weimiao Yu Jun Xu Zhaoming Ye | 2023 | CAAI Transactions on Intelligence Technology2023,8,3: | 0 |
| 11 | Light scattering based analyses of the effects of bovine serum proteins on interactions of magnetite spherical particles with cells显示文摘Information concerns endocytosis and autophagic effects of magnetite particles is crucial for understanding the particle-cell interactions. In this work, we investigated the effects of bovine serum proteins on the endocytosis of magnetite spherical particles(MSPs). Autophagic effects of MSPs in breast cancer cells were studied. Light scattering based flow cytometry and microscopy were used for evaluating the uptake potential of MSPs by cells and the cellular autophagosome accumulation. Results showed bovine serum proteins significantly reduced the endocytosis of MSPs by decreasing their adsorption to cell membranes. Additionally, serum proteins had influences on the endocytic mechanisms of MSPs.Autophagosome accumulation could be caused by the internalized MSPs rather than the particles associated with cell membrane. Above fundamental findings promote our understandings upon the interactions of MSPs with cells. Light scattering based methods were proved to be simple and effective.The present work may promote their application in studies upon endocytosis of metallic particles in the future. | Lingling Guo Ting Wang Zhan Chen Nongyue He Yaozhong Chen Tao Yuan | 2018 | Chinese Chemical Letters2018,29,8: | 0 |
