1In situ scanning electron microscopy observation of deformation and fracture behavior of Ti-3Zr-2Sn-3Mo-25Nb alloy显示文摘The plastic deformation and fracture processes of Ti-3Zr-2Sn-3Mo-25Nb alloy for surgical implants were directly observed by in situ scanning electron microscopy(SEM).The effect of phase transformations on deformation-induced martensitic transformation accompanying the cyclic tensile fracture processes was investigated.The results reveal that the metastable alpha martensites(α″) promotes deformation-induced martensitic transformation to ductile fracture,whereas the omega(ω) and alpha(α) phases drastically prevent slip dislocation and deformation-induced martensitic transformation to brittle fracture.Ma, Xiqun Yu, Zhentao Han, Yong Song, Xiping Sun, Qiaoyan 2012Rare Metals2012,31,4:9
2Comparison of labeling methods and time course of traumatic brain injury-induced cell death in mice显示文摘BACKGROUND:Various molecular mechanisms of cell death following traumatic brain injury have been previously described.However,the time course of cell death remains unclear.TUNEL and Fluoro-Jade B labeling have been widely used to label apoptotic cells and neuronal degeneration.Propidium iodide (PI) functions as a biomarker of cell death in vivo.OBJECTIVE:To explore the role of PI labeling compared to TUNEL and Fluoro-Jade B staining for detecting neural cell death,and to observe time course of traumatic brain injury-induced cell death in mice.DESIGN,TIME AND SETTING:A randomized,controlled,animal experiment was performed at the Laboratory of Aging and Nervous Diseases,Soochow University from September 2007 to December 2008.MATERIALS:PI (B1221) was purchased from Sigma,USA.TUNEL kit was purchased from Roche Molecular Biochemicals,USA.Fluoro-Jade B was purchased from Chemicon,USA.METHODS:A total of 70 healthy,male,Kunming mice were randomly assigned to sham-surgery (n=5) and model (n=65) groups.Traumatic brain injury was established using the controlled cortical impact method.PI was intraperitoneally injected at 1 hour prior to animal sacrifice.MAIN OUTCOME MEASURES:TUNEL,Fluoro-Jade B,and PI-positive cells were quantified using a double-labeling method to determine the time course of traumatic brain injury-induced cell death.RESULTS:PI labeled cells in an earlier phase of cell death than TUNEL and Fluoro-Jade B labeling.PI-positive cells were observed immediately following injury,and the numbers rapidly increased in injured brain areas at 1 hour,peaked at 24-48 hours,and subsequently decreased at 3-21 days post-injury.TUNEL-labeled cells were significantly increased at 12 hours,while Fluoro-Jade B-labeled cells were increased at 6 hours after injury,with cells still visible at 6-48 hours post-injury.Moreover,a greater number of PI-positive cells were observed compared to TUNEL-and Fluoro-Jade B-labeled cells.CONCLUSION:PI labeling is more sensitive and reliable than TUNEL and Fluoro-Jade B staining for detecting cell death following traumatic brain injury.Moreover,PI labeling can function as a reliable marker to estimate the entire time course of cell death.Chengliang Luo Xiping Chen Hong Ni Qianqian Li Rui Yang Yuxia Sun Guangyou Zhu Luyang Tao 2010Neural Regeneration Research2010,5,9:6
33D printing of silk fibroin-based hybrid scaffold treated with platelet rich plasma for bone tissue engineering显示文摘3D printing/bioprinting are promising techniques to fabricate scaffolds with well controlled and patient-specific structures and architectures for bone tissue engineering.In this study,we developed a composite bioink consisting of silk fibroin(SF),gelatin(GEL),hyaluronic acid(HA),and tricalcium phosphate(TCP)and 3D bioprinted the silk fibroin-based hybrid scaffolds.The 3D bioprinted scaffolds with dual crosslinking were further treated with human platelet-rich plasma(PRP)to generate PRP coated scaffolds.Live/Dead and MTT assays demonstrated that PRP treatment could obviously promote the cell growth and proliferation of human adipose derived mesenchymal stem cells(HADMSC).In addition,the treatment of PRP did not significantly affect alkaline phosphatase(ALP)activity and expression,but significantly upregulated the gene expression levels of late osteogenic markers.This study demonstrated that the 3D printing of silk fibroin-based hybrid scaffolds,in combination with PRP post-treatment,might be a more efficient strategy to promote osteogenic differentiation of adult stem cells and has significant potential to be used for bone tissue engineering.Liang Wei Shaohua Wu Mitchell Kuss Xiping Jiang Runjun Sun Reid Patrick Xiaohong Qin Duan Bin 2019Bioactive Materials2019,4,1:6
4Design theory and experimental investigation of the low frequency and high power rare earth magnetostrictive flextensional transducer (Ⅰ). Theoretical part显示文摘The energy relationships among all the elements, by which the magnetostrictive transducers are manufactured, in Finite Element Method (FEM) are analyzed, then the expres- sions of FEM dynamics equations and performances formulas for magnetostrictive transducers are derived. The vibrating modes of the class VII transducer and its shell vibration are calcu- lated theoretically and the results point out that there is a breathing mode and if the transducer works at this mode, the transducer will vibrate with a greater volume speed and source level.HE Xiping (Applied acoustic institute, Shaanxi Teachers University Xi’an 710072) (College of Marine Engineering Northwestern Polytechnic University Xi’an 710O72) SUN Jincai LI Bin (Colloge of Marine Engineering Northwestern Polytechnic University Xi’an 71 2001Chinese Journal of Acoustics2001,20,4:6
5Assessment of cognitive dysfunction in traumatic brain injury patients:a review显示文摘Traumatic brain injury(TBI)is one of the major causes of human mortality and morbidity in the world.Brain injury could affect the core of a person’s being–their thinking,memory,personality and behaviour.Electrophysiological markers from the human electroencephalogram and brain imaging provide a rich source of data which helps to elucidate specific processing impairments in TBI patients.To assess the cognitive and social function in traumatic brain injury patients,this review will focus on some of methods for assessing the disabling cognitive and social function deficits induced by TBI.There are many new technologies available to address TBI and recognition related questions.Integration of the various techniques will help to facilitate our comprehending of TBI,cognitive function and social function,and improve treatment and rehabilitation.Huiyan Sun Chengliang Luo Xiping Chen Luyang Tao 2017Forensic Sciences Research2017,2,4:5
6Fabrication of(TiB/Ti)-TiAl composites with a controlled laminated architecture and enhanced mechanical properties显示文摘The(TiB/Ti)-TiAl composites with a laminated structure composing of alternating TiB/Ti composite layers,α_(2)-Ti_(3)Al interfacial reaction layers of andγ-TiAl layers were successfully pre pared by spark plasma sintering of alternately stacked Tib_(2)/Ti powder layers and TiAl powder layers.And the influence of thickness ratio of Tib_(2)/Ti powder layers to TiAl powder layers on microstructure evolution and mechanical properties of the re sulting(TiB/Ti)-TiAl laminated composites were investigated systemically.The results showed that the thickening ofα_(2)-Ti_(3)Al layers which originated from the reaction of Ti and TiAl was significantly hindered by introducing Tib_(2)particles into starting Ti powders.As the thickness ratio of Tib_(2)/Ti powder layers to TiAl powder layers increased,the bending fracture strength and fracture toughness at room temperature of the final(TiB/Ti)-TiAl laminated composites were remarkably improved,especially for the(TiB/Ti)-TiAl composites prepared by Tib_(2)/Ti powder layers with thickness of 800μm and TiAl powder layers with thickness of 400μm,whose fracture toughness and bending strength were up to 51.2 MPa·m^(1/2)and 1456 MPa,respectively,293%and 108%higher than that of the monolithic TiAl alloys in the present work.This was attributed to the addition of high-performance network TiB/Ti composite layers.Moreover,it was noteworthy that the ultimate tensile strength at 700℃of(TiB/Ti)-TiAl composites fabricated by 400μm thick Tib_(2)/Ti powder layers and 400μm thick TiAl powder layers was as high as that at 550℃of network TiB/Ti composites.This means the service temperature of(TiB/Ti)-TiAl laminated composites was likely raised by 150℃,meanwhile a good combination of high strength and high toughness at ambient tempe rature could be maintained.Finally,the fracture mechanism of(TiB/Ti)-TiAl laminated composites was proposed.Hao Ding Xiping Cui Naonao Gao Yuan Sun Yuanyuan Zhang Lujun Huang Lin Geng 2021Journal of Materials Science & Technology2021,,3:3
7Design and Optimization of a Mechanical Variable-Leakage-Flux Interior Permanent Magnet Machine with Auxiliary Rotatable Magnetic Poles显示文摘A novel mechanical variable-leakage-flux interior permanent magnet machine(MVLF-IPMM)is proposed for electric vehicles(EVs)in this paper,which employs a mechanical flux-regulating device and auxiliary rotatable magnetic poles.The magnetic poles acting as the flux adjustors can be rotated by the additional device to vary the leakage flux in magnetic circuit and realize the adjustment of the PM flux linkage.Due to the flux-regulating effect,the flux distribution in this machine is complex and changeable.Therefore,the working principle is illustrated in detail.To obtain the perfect coordination between the dominant magnetic poles and auxiliary magnetic poles,a multi-objective optimization method is presented based on the parameter sensitivity analysis combining with the Coefficient of Prognosis(CoP).Then,some design parameters with strong sensitive are selected by the sensitivity analysis and the initial model of the proposed motor is optimized by utilizing the multi-objective genetic algorithm(MOGA).According to the result of the optimization,the machine performances of the initial and the optimal design under the different flux states are compared and analyzed to verify the validity of the new variable-flux motor and the optimization method.Tongze Sun Xiping Liu Yongling Zou Chaozhi Huang Jianwei Liang 2021CES Transactions on Electrical Machines and Systems2021,5,1:3
8Detection of QTL and QTN and candidate genes for oil content in soybean using a combination of four-way-RIL and germplasm populations显示文摘Soybean is a source of edible oil for humans and provides a third of the vegetable oil consumed worldwide.Increasing seed oil content in seeds is thus a key objective in soybean breeding.In the present study,a four-way recombinant inbred line(FW-RIL)population comprising 144 lines,planted in 10 environments,and a germplasm panel of 455 accessions,planted in two environments,were used to collect oil-content phenotypes.First,59 quantitative trait loci(QTL)were detected in the FW-RIL population by inclusive complete interval mapping on a linkage map consisting of 2232 single-nucleotide polymorphism(SNP)markers.Also in the FW-RILs,44 quantitative trait nucleotides(QTNs)were detected by association analysis using 109,676 SNP markers and fivemethods of multi-locus genome-wide association study.Second,77 QTN were detected by association analysis in the germplasm panel using 63,306 markers.Comparison of the QTL and QTN suggested four QTN controlling oil content.Pathway analysis was performed on genes in attenuation regions of these four QTN,and two candidate genes involved in the synthesis or metabolism of soybean oil were identified.These findings provide useful information about the genetics of oil content and may contribute to its genetic improvement by marker-assisted selection.Xiyu Li Kaixin Zhang Xu Sun Shanshan Huang Jiajing Wang Chang Yang Mahfishan Siyal Chao Wang Chunlan Guo Xiping Hu Wen-Xia Li Hailong Ning 2020The Crop Journal2020,8,5:2
9Isolation and Identification of Squash Leaf Curl China Virus in Zucchini显示文摘[Objectives]In 2019,virus diseases occurred widely on zucchini planted in Shandong Province.The disease symptom was different from previous reports.This study aimed to identify the pathogen causing the zucchini virus disease.[Methods]Ten diseased zucchini leaves were collected in the field and used as materials for PCR and sequencing.[Results]PCR detection and sequencing showed that the nucleotide sequence of the amplified fragment had the highest identity with the squash isolate of squash leaf curl China virus(SLCCNV)(MW389919.1)in Guangdong Province.Primers were further designed for amplifying the full-length SLCCNV.The full-length DNA-A was 2730 bp(OM692270.1),and the full-length DNA-B was 2711 bp(OM692269.1).Through sequence alignment,it was found that the DNA-A sequence shared identity of 89.65%-99.42%with registered SLCCNV,and the identity with the SLCCNV-GDHY pumpkin isolate(MW389919.1)in Guangdong was the highest,at 99.42%.The DNA-B sequence was identical with registered SLCCNV in the range of 81.82%-97.29%,and the identity with the SLCCNV-GDHY pumpkin isolate(MW389918.1)in Guangdong,was the highest,at 97.29%.Therefore,it was speculated that SLCCNV is the pathogen of zucchini virus disease.Since the virus was first found on zucchini in Shandong,it was named SLCCNV-SD.[Conclusions]This study provides materials for the research on the spread of SLCCNV in China and the analysis of population genetic characteristics,as well as a reference for the prevention and control of the virus in zucchini.Huixian SHI Yimin GU Xingsheng LI Xiping SUN Yangdong GUO Xiaowei YUAN 2022Agricultural Biotechnology2022,11,5:1
