| 1 | Spatial-resolved metabolomics reveals tissue-specific metabolic reprogramming in diabetic nephropathy by using mass spectrometry imaging显示文摘Detailed knowledge on tissue-specific metabolic reprogramming in diabetic nephropathy(DN)is vital for more accurate understanding the molecular pathological signature and developing novel therapeutic strategies.In the present study,a spatial-resolved metabolomics approach based on air flowassisted desorption electrospray ionization(AFADESI)and matrix-assisted laser desorption ionization(MALDI)integrated mass spectrometry imaging(MSI)was proposed to investigate tissue-specific metabolic alterations in the kidneys of high-fat diet-fed and streptozotocin(STZ)-treated DN rats and the therapeutic effect of astragalosideⅣ,a potential anti-diabetic drug,against DN.As a result,a wide range of functional metabolites including sugars,amino acids,nucleotides and their derivatives,fatty acids,phospholipids,sphingolipids,glycerides,carnitine and its derivatives,vitamins,peptides,and metal ions associated with DN were identified and their unique distribution patterns in the rat kidney were visualized with high chemical specificity and high spatial resolution.These region-specific metabolic disturbances were ameliorated by repeated oral administration of astragaloside Ⅳ(100 mg/kg)for 12 weeks.This study provided more comprehensive and detailed information about the tissue-specific metabolic reprogramming and molecular pathological signature in the kidney of diabetic rats.These findings highlighted the promising potential of AFADESI and MALDI integrated MSI based metabolomics approach for application in metabolic kidney diseases. | Zhonghua Wang Wenqing Fu Meiling Huo Bingshu He Yaqi Liu Lu Tian Wanfang Li Zhi Zhou Baili Wang Jianzhen Xia Yanhua Chen Jinfeng Wei Zeper Abliz | 2021 | Acta Pharmaceutica Sinica B2021，11，11： | 7 |
| 2 | Enhanced Hole-Injection Property in an OLED with a Self-assembled Monolayer of Hole-Transporting TPD on Thin Au as the Anode显示文摘A thioester-functionalized triphenylamine hole-transporting molecule(TPD-SAc) was synthesized and self-assembled to form a monolayer on an ultra-thin Au film supported on indium-tin oxide glass. The modified surface was characterized by aqueous contact angle, ellipsometer, atomic force microscopy, X-ray photoelectron spectroscopy, and ultraviolet photoelectron spectrometer to substantiate the formation of compact and pinhole-free monolayers. The modified organic light emitting diode device [indium-tin oxide/Au(5 nm)/self-assembled monolayers(SAM)/TPD(50 nm)/Alq_3(40 nm)/TPBI(15 nm)/LiF(1 nm)/Al(100 nm)] showed a luminance of 7303.90 cd/m^2 and a current efficiency of 8.49 cd/A with 1.78 and 2.29-fold increase, respectively, compared to the control device without SAM. The improvements were attributed to the enhanced compatibility of the organic–inorganic interface, matched energy level by introduction of an energy mediating step and superior hole-injection property of SAM molecules. | Zhi Shang Dongzhi Liu Tianyang Wang Xi Yu Baili Li Wei Li Wenping Hu Xueqin Zhou | 2018 | Transactions of Tianjin University2018，24，6： | 2 |
| 3 | 论莫言小说身体叙事的古典美学倾向显示文摘“身体”是中国当代文学的重要叙写对象,但当代文学中的身体叙写存在着较为普遍的工具化、欲望化、消费化倾向。莫言通过对中国古典“多重身体审美感知”“身心不二”“天人合一”身体审美观的自觉复魅,形成了一种身体叙写的“莫言经验”。这种经验,可以为当代文学身体叙写提供一种克服肉身与灵魂割裂、身体与大地分离的重要参考。 | 李占伟 Wang Baili | 2022 | 粤海风2022，，2： | 0 |
| 4 | Effects of nitrogen fertilizer on protein synthesis, accumulation, and physicochemical properties in common buckwheat显示文摘Nitrogen(N)fertilization affects grain quality in common buckwheat(Fagopyrum esculentum Moench).But the effects of N fertilizer on various buckwheat protein parameters are not fully understood.This study aimed to investigate the synthesis,accumulation,and quality of buckwheat protein under four N application rates in the Loess Plateau,China.Optimal N application(180 kg N ha-1)improved yield,agronomic traits,and N transport and increased protein yield and protein component accumulation.Prolamin and glutelin accumulation first increased and then decreased with increasing N application.The relationships between the contents of protein components and the amount of applied N generally followed quadratic functions.Nitrate reductase and glutamine synthetase activities first increased and then decreased with increasing N levels.Optimal N fertilizer increased the waterholding capacity and thermal stability of buckwheat protein and reduced its emulsification capacity,but negligibly changed its oil-absorption capacity.Hydrophobic amino acids and glutelin content were the main factors affecting protein quality. | Chenxi Wan Licheng Gao Jiale Wang Xinhui Lei Jincai Tao Baili Feng Jinfeng Gao | 2023 | The Crop Journal2023，11，3： | 0 |
| 5 | Sequence modulation of tunneling barrier and charge transport across histidine doped oligo-alanine molecular junctions显示文摘Series tunneling across peptides composed of various amino acids is one of the main charge transport mechanisms for realizing the function of protein. Histidine, more frequently found in redox active proteins, has been proved to be efficient tunneling mediator. While how it exactly modulates charge transport in a long peptide sequence remains poorly explored. In this work, we studied charge transport of a model peptide junction, where oligo-alanine peptide was doped by histidine at different position,and the series of peptides were self-assembled into a monolayer on gold electrode with soft EGa In as top electrode to form molecular junction. It was found that histidine increased the overall conductance of the peptide, meanwhile, its position modulated the conductance as well. Quantitative analysis by transport model and ultraviolet photoelectron spectroscopy(UPS) indicated a sequence dependent energy landscape of the tunneling barrier of the junction. Density-functional theory(DFT) calculation on the electronic structure of histidine doped oligo-alanine peptides revealed localized highest occupied molecular orbital(HOMO) on imidazole group of the histidine, which decreased charge transport barrier. | Baili Li Xuan Ji Lixian Tian Xianneng Song Ziyan Wang Hira Khalid Xi Yu Lejia Wang Wenping Hu | 2021 | Chinese Chemical Letters2021，32，12： | 0 |
| 6 | The boron transporter SiBOR1 functions in cell wall integrity, cellular homeostasis, and panicle development in foxtail millet显示文摘Boron(B) is an essential micronutrient for vascular plant growth. Both B deficiency and toxicity can impair tissue development in diverse plant species, but little is known about the effect of B on reproductive panicle development and grain yield. In this study, a mutant of Setaria italica exhibiting necrotic panicle apices was identified and designated as sibor1. Sequencing revealed a candidate gene, Si BOR1, with a G-to-A alteration at the seventh exon. Knockout transgenic lines generated by clustered regularly interspaced short palindromic repeats and their associated protein-9 also had necrotic panicles, verifying the function of Si BOR1. Si BOR1 encoded a membrane-localized B efflux transporter, co-orthologous to the rice BOR1 protein. Si BOR1 was dominantly expressed in panicles and displayed a distinct expression pattern from those of its orthologs in other species. The induced mutation in Si BOR1 caused a reduction in the B content of panicle primary branches, and B deficiency-associated phenotypes such as thicker cell walls and higher cell porosity compared with Yugu 1. Transcriptome analysis indicated that differentially expressed genes involved in cell wall biogenesis, jasmonic acid synthesis, and programmed cell death response pathways were enriched in sibor1. q PCR analysis identified several key genes, including phenylalanine ammonia-lyase(Si PAL) and jasmonate-ZIM-domain(Si JAZ) genes, responsive to B-deficient conditions. These results indicate that Si BOR1 helps to regulate panicle primary branch development to maintain grain yield in S. italica. Our findings shed light on molecular mechanisms underlying the relationship between B transport and plant development in S. italica. | Hailong Wang Sha Tang Hui Zhi Lihe Xing Haoshan Zhang Chanjuan Tang Enbo Wang Meicheng Zhao Guanqing Jia Baili Feng Xianmin Diao | 2022 | The Crop Journal2022，10，2： | 0 |
