| 1 | Structural Description of Polyaromatic Nucleus in Residue显示文摘原子磁性的回声光谱学(~ 1H-NMR ) ,同步荧光 spectrometry (SFS ) 和钌离子催化的质子氧化(RICO ) 方法被用来在阿曼残余部分决定 polyaromatic 原子核的化学结构。~ 1H-NMR 分析的结果证明在 aromatics,树脂和沥青质单位的芳香的戒指的平均数字分别地是 3.2, 5.6 和 8.2。SFS 被用来在残余部分,在 aromatics 的芳香的戒指的主要分发范围,树脂和沥青质调查芳香的戒指的分发分别地是 3-4 戒指, 3-5 戒指和超过 5 枚戒指。在残余部分的芳香的网络被氧化生产众多的羧基的酸。benzenepolycarboxylic 酸的类型和内容 benzenetricarboxylic 酸, benzenetetracarboxylic 酸, benzenepentacarboxylic 酸和 benzenehexacarboxylic 酸例如酞酸酸,在核心揭示了芳香的原子核的压缩类型。联本基部分(BIPH ) ,压缩 cata 的部分(CATA ) ,压缩仙子的部分(仙子) 和压缩索引(BCI ) 基于形成的 benzenepolycarboxylic 酸被计算。结果暗示在所有残余部分有更少的联本基类型结构。aromatics 部分几乎由压缩 cata 的类型系统组成,并且,沥青质部分完全在树脂部分由压缩仙子的类型系统组成共存二种类型,此处压缩仙子的类型在压缩 cata 的类型上是占优势的。基于在学习,部件 -aromatics, 树脂和沥青质获得的分析结果 - 被给多半结构的模型。 | Zhang Huicheng Yan Yongjie Sun Wanfu Wang Jifeng | 2007 | China Petroleum Processing & Petrochemical Technology2007，9，3： | 1 |
| 2 | Smart nanoprobe based on two-photon sensitized terbium-carbon dots for dual-mode fluorescence thermometer and antibacterial显示文摘Accurate temperature measurement plays an important role in a variety of industrial processes and scientific researches.In our work,the dual-mode temperature response nanoprobe CDs-Tb-TMPDPA containing a two-photon ligand(4-(2,4,6-trimethoxyphenyl)-pyridine-2,6-dicarboxylic acid,TMPDPA)sensitized Tb3+as a temperature-sensitive unit and carbon dots(CDs)as photothermal reagent and a fluorescence reference unit,have been designed and synthesized.In this system,both the fluorescence intensity ratio and the fluorescence lifetime have a good response to temperature.In additio n,due to the excellent photothermal conversion capability of CDs,photothermal antibacterial ability was also tested.Based on the temperature dependence of the fluorescence and the two-photon excitation characteristics of CDs-Tb-TMPDPA,the nanoprobe can also be used in the anti-counterfeiting.Our finding opens a new prospect for the use of two-photon sensitized dual-mode fluorescence thermometers. | Huicheng Yan Hongyuhang Ni Yiwei Yang Changfu Shan Xiaoxi Yang Xiangkai Li Jing Cao Wenyu Wu Weisheng Liu Yu Tang | 2020 | Chinese Chemical Letters2020，31，7： | 1 |

| 4 | A smart nanoprobe based on luminescent terbium metal-organic framework coated gold nanorods for monitoring and photo-stimulated combined thermal-chemotherapy显示文摘Real-time monitoring and accurate treatment are of great significance for reducing the side effects during the cancer therapy.In this work,we rationally prepared a smart nanoprobe based on core-shell terbium metal-organic gramework(MOF)with highly effective photothermal conversion capacity and drug release efficiency under near-infrared light irradiation for real-time fluorescence imaging-guided multimodal therapy.The nanoprobe can achieve prominent photothermal therapy and controllable drug release,act as a fluorescence thermometer,and also real-time feedback of temperature is expected to be achieved.At the same time,the two-photon ligand design significantly improves the tissue penetration ability of the nanoprobe.Our work is expected to provide a reference for precise treatment and real-time monitoring of tumors and at the same time provide new ideas for the formulation of individualized treatment plans. | Tong Zhang Liying Qin Liangliang Liu Meina Zhang Tianyi Du Yifan Fan Huicheng Yan Pingru Su Ping Zhou Yu Tang | 2022 | Journal of Rare Earths2022，40，9： | 0 |
| 5 | Mitochondrial deoxyguanosine kinase is required for female fertility in mice显示文摘Mitochondrial homeostasis plays a pivotal role in oocyte maturation and embryonic development.Deoxyguanosine kinase(DGUOK)is a nucleoside kinase that salvages purine nucleosides in mitochondria and is critical for mitochondrial DNA replication and homeostasis in non-proliferating cells.Dguok loss-of-function mutations and deletions lead to hepatocerebral mitochondrial DNA deletion syndrome.However,its potential role in reproduction remains largely unknown.In this study,we find that Dguok knockout results in female infertility.Mechanistically,DGUOK deficiency hinders ovarian development and oocyte maturation.Moreover,DGUOK deficiency in oocytes causes a significant reduction in mitochondrial DNA copy number and abnormal mitochondrial dynamics and impairs germinal vesicle breakdown.Only few DGUOK-deficient oocytes can extrude their first polar body during in vitro maturation,and these oocytes exhibit irregular chromosome arrangements and different spindle lengths.In addition,DGUOK deficiency elevates reactive oxygen species levels and accelerates oocyte apoptosis.Our findings reveal novel physiological roles for the mitochondrial nucleoside salvage pathway in oocyte maturation and implicate DGUOK as a potential marker for the diagnosis of female infertility. | Yake Gao Rui Dong Jiacong Yan Huicheng Chen Lei Sang Xinyi Yao Die Fan Xin Wang Xiaoyuan Zuo Xu Zhang Shengyu Yang Ze Wu Jianwei Sun | 2024 | Acta Biochimica et Biophysica Sinica2024，56，3： | 0 |
