2YAGG:Ce transparent ceramics with high luminous efficiency for solid-state lighting application显示文摘A series of Y2.985Al5–xGaxO12:0.015Ce(YAGG:Ce,x=0,1,2,3,4,5)transparent ceramics were prepared via a solid-state reaction method.Two-step sintering technique was proved to be an effective approach to prepare functional ceramics with high Ga concentration,and Y3Ga5O12(YGG)transparent ceramic was successfully prepared for the first time.According to the variation of Al/Ga ratio,regulation of band structure and luminescence properties of YAGG:Ce transparent ceramics were effectively investigated.When Ga substitutes Al sites,the tetrahedral site is more favorable compared to the octahedral site for Ga to occupy according to the first-principle calculation.A continuous blue shift of the emission from 565 to 515 nm was achieved as Ga was gradually introduced into Y3Al5O12:Ce matrix.High quality green light was obtained by coupling the YAGG:Ce ceramics with commercial blue InGaN chips.Transparent luminescence ceramics accomplished in this work can be quite prospective for high power LED application.Hui HUA Shaowei FENG Zhongyu OUYANG Hezhu SHAO Haiming QIN Hui DING Qiping DU Zhijun ZHANG Jun JIANG Haochuan JIANG 2019Journal of Advanced Ceramics2019,8,3:13
3The maize late embryogenesis abundant protein Zm DHN13 positively regulates copper tolerance in transgenic yeast and tobacco显示文摘Late embryogenesis abundant (LEA) proteins accumulate in the late stage of plant seed development, and are upregulated in most plants during drought, cold, heat, or salinity stress. LEA proteins can be classified by amino-acid sequence into seven groups. Dehydrins belong to LEA protein group Ⅱ. In previous studies, the maize KS type dehydrin ZmDHN13 increased the tolerance of transgenic tobacco to oxidative stress. In the present study, ZmDHN13 was identified under copper stress conditions, and the protein was then characterized using transgenic yeast and tobacco plants to investigate its functions. ZmDHN13 bound Cu2+. Its overexpression in transgenic tobacco conferred tolerance to copper stress by binding metals and reducing the accumulation of reactive oxygen species (ROS). Three conserved domains displayed a cooperative effect under copper stress conditions.Yang Liu Daxing Li Qiping Song Tianpeng Zhang Dequan Li Xinghong Yang 2019The Crop Journal2019,7,3:3

11DLX5 promotes Col10a1 expression and chondrocyte hypertrophy and is involved in osteoarthritis progression显示文摘Osteoarthritis(OA)has been considered non-reversible as articular cartilage wears down with limited repair capacity.Enhanced chondrocyte hypertrophy and increased type X collagen gene(COL10A1)expression have been associated with OA.Therefore,regulators controlling collagen X expression and chondrocyte hypertrophy may play a role in OA intervention.Here,we investigated how Distal-less homeobox 5(DLX5),the distal-less homeobox family member,controls murine Col10a1 gene expression and chondrocyte hypertrophy in chondrogenic cell models and its role in a murine OA model.Through qRT-PCR and Western blot analyses,we detected significantly increased levels of COL10A1 and DLX5 in hypertrophic MCT and ATDC5 cells compared to their proliferative stage.Forced expression of Dlx5 further increases,while knockdown of Dlx5 decreases COL10A1 expression in hypertrophic MCT cells.We have performed dual-luciferase reporter and ChiP assays and demonstrated that DLX5 promotes reporter activity through direct interaction with Col10a1 cis-enhancer.We established a murine OA model and detected markedly increased COL10A1 and DLX5 in the articular cartilage and subchondral bone of the OA mice compared with the controls.Notably,forced overexpression of DLX5 in hypertrophic MCT cells up-regulates RUNX2,and adjacent DLX5 and RUNX2 binding sites have previously been found within the Col10a1 cis-enhancer.Together,our data suggest that DLX5 may cooperate with RUNX2 to control cell-specific Col10a1 expression and chondrocyte hypertrophy and is involved in OA pathogenesis.Jinnan Chen Fangzhou Chen Xuan Wu Huiqin Bian Chen Chen Xiaojing Zhang Ruoxuan Hei Xiaotong Yang Haochun Yuan Qian Wang Yaojuan Lu Longwei Qiao Qiping Zheng 2023Genes & Diseases2023,10,5:1
12Effect of ultrasonic modification on the protective activity of Flammulina velutipes polysaccharide to prevent ethanol-induced injury on GES-1 cells显示文摘Flammulina velutipes(F.velutipes)polysaccharides were modified by ultrasound at the rated power of 150 W and 900 W.The monosaccharide composition,ultraviolet-visible,and Fourier transform infrared spectral characteristics of F.velutipes polysaccharides(FVP)and their ultrasonic modification products(U-FVPs)were determined.The protective effects of FVP and U-FVPs on human gastric mucosal cells GES-1 were confi rmed for the first time.The mole ratios of glucose and galactose were decreased and the mole ratio of mannose was increased after ultrasonic modification.Compared with the original FVP and the FVP modifi ed by ultrasound of 150 W(U-FVP1),the FVP modifi ed by ultrasound of 900 W(U-FVP2)could better prevent ethanol-induced damage to GES-1 cells.With increasing ultrasound intensity,the protective effect of FVPs on GES-1 cells was significantly enhanced by more effective prevention of intracellular reactive oxygen species(ROS)production and more promotion of expression of triglyceride factor 2(TFF2),prostaglandin E2(PGE2),epidermal growth factor(EGF),and transforming growth factorβ1(TGF-β1)mRNA.The ultrasonic modifi cation might be an effective way to develop novel F.velutipes polysaccharides that could effectively resist the gastric injury caused by excessive alcohol consumption.Jinrong Xiao Xin Chen Jingsi Zhang Yifan Wang Lei Zhong Qiping Zhan Qiuhui Hu Liyan Zhao 2023Food Science and Human Wellness2023,12,6:0

15Effects of two vectors on the expression of the NbNAC1 transcription factor and preparation of its polyclonal antibody显示文摘The NAC(NAM,ATAF,and CUC)superfamily is one of the largest plant-specific families containing transcription factors.An increasing number of studies suggest that NAC1 is involved in plants response to different biotic and abiotic stimulis.Nicotiana benthamiana is a widely used system for evaluating plant-pathogen interactions.In order to study the biochemical function of NbNAC1,NbNAC1 protein and antibody are essential.Therefore,we focused on developing a prokaryotic expression system for producing the Nicotiana benthamiana NbNAC1 protein of in Escherichia coli and the preparation of its polyclonal antibody.Firstly,we constructed two different molecular weight prokaryotic expression vectors:pGE vector with GST tag(pGEX4T-1–NbNAC1)and pET expression vector with His tag(pET28a-NbNAC1).The NbNAC1 protein can be successfully expressed in both vectors.The His-tagged NbNAC1 proteins are insoluble,while the GST-tagged NbNAC1 proteins are partially soluble.We then successfully purified and enriched both proteins.The His-tagged NbNAC1 was chosen to immunize rabbits owing to an unknown protein accompanying the GST-tagged NbNAC1.The anti-NbNAC1 polyclonal antibody had good specificity and could be used in subsequent protein-related studies.FENG ZHU QINQIN ZHANG YANGKAI ZHOU QIPING ZHANG MENGYAO CAO ZHAOLIN JI 2022BIOCELL2022,46,9:0
16Regulation of different light conditions for efficient biomass production and protein accumulation of Spirulina platensis显示文摘Light plays an important role in the photosynthesis and metabolic process of microalgae.However,how different light conditions regulate the biomass production and protein accumulation of microalgae is mostly unknown.In this study,the influence of different light conditions,including light colors,densities,and light:dark cycles on the cell growth and biochemical composition of Spirulina platensis was symmetrically characterized.Under different colored lights,S.platensis all shows an increase trend within the increased light intensity ranges;however,each showing different optimal light intensities.At the same light intensity,different colored lights show different growth rate of S.platensis following the sequence of red>white>green>yellow>blue.The maximum growth rate and protein accumulation were determined as 21.88 and 5.10 mg/(L·d)when illuminated under red LED.The energy efficiency of different light sources was calculated and ranked as red>white>blue≈green>yellow.Transcriptomic analysis suggests that red light can promote cell growth and protein accumulation by upregulating genes related to photosynthesis,carbon fixation,and C-N metabolism pathways.This study provides a conducive and efficient way to promote biomass production and protein accumulation of S.platensis by regulating light conditions.Yufei ZHANG Xianjun LI Yuhui LI Shiqi LIU Yanrui CHEN Miao JIA Xin WANG Lu ZHANG Qiping GAO Liang ZHANG Daoyong YU Baosheng GE 2024Journal of Oceanology and Limnology2024,42,1:0

18Isolation and polymorphic frequency detection of a novel STR on human chromosome 14q24.3显示文摘A single copy fragment (FD14_ca 1) containing 22 CA repetitive units was isolated with (CA) 15 oligonucleotide probe from a human chromosome 14q24 3 probe pool generated by microdissection, and proved to be a new short tandem repeat (STR) sequence through querying in GenBank of NCBI. The STR has 11 alleles in Chinese, and its polymorphic information content (PIC) is 0 85. Mendelian segregation was shown in 2 Chinese pedigrees with two generations. This STR has been accurately relocalized on chromosome 14q24 3 by fluorescence in situ hybridization (FISH). The accession numbers of this STR in GDB and GenBank database are D14S1435 and G31413 respectively. This STR would be able to be regarded as a novel genetic marker which can increase the genetic map accuracy in this chromosome region and improve the gene diagnosis on some genetic diseases located in chromosome 14q24 3 band.Zhang Min Yu Longa Zheng Qiping Hu Peirong Sun Xiyuan Zhao Shouyuan 1998Chinese Science Bulletin1998,43,4:0
