        Effects of IBA on rooting ability of Cinnamomum bodinieri citral type micro-shoots from transcriptomics analysis

        Xiao Zufei,Jin Zhinong,Zhang Beihong,Li Feng,Yu Faxin,Zhang Haiyan,Lü Xiongwei,Zhang Jie 한국식물생명공학회 2020 Plant biotechnology reports Vol.14 No.4

        Cinnamomum bodinieri is a useful plant that could be improved by increasing its cultivation rate. To explore the optimal concentration of exogenously applied IBA for root formation and development in the C. bodinieri citral type, micro-shoots and the fresh tissues of their bases were subjected to morphological and transcriptome analyses, respectively. When plantedQuery on a rooting medium (1/2 MS) with 1.5 mg/L IBA for 25 days, the rooting rates and root numbers were significantly higher than those obtained with 0, 0.5, 1.0, or 2.0 mg/L IBA treatment. Transcriptome analyses conducted 0 day, 7 days, 11 days, and 14 days after planting in the optimal rooting medium demonstrated that the IBA modified the plant’s carbohydrate metabolism and auxin signaling pathway. The root-specific expressions of TIR1, GH3, and SAUR were up-expressed while AUX/IAA was repressed, which contributed to the formation of lateral root initiation sites and root cell elongation. At the same time, d-glucose synthesis increased and the accumulation of starch decreased as more carbohydrates were used to form and develop roots instead of being used for the rapid cell division required for shoot growth. This study identified the optimal rooting medium for the C. bodinieri citral type and determined the molecular mechanisms involved in the regulation of exogenously applied IBA during root formation and development at the transcriptional level.

        Tanshinone IIA Protects Endothelial Cells from H<sub>2</sub>O<sub>2</sub>-Induced Injuries via PXR Activation

        ( Haiyan Zhu ),( Zhiwu Chen ),( Zengchun Ma ),( Hongling Tan ),( Chengrong Xiao ),( Xianglin Tang ),( Boli Zhang ),( Yuguang Wang ),( Yue Gao ) 한국응용약물학회 2017 Biomolecules & Therapeutics(구 응용약물학회지) Vol.25 No.6

        Tanshinone IIA (Tan IIA) is a pharmacologically active substance extracted from the rhizome of Salvia miltiorrhiza Bunge (also known as the Chinese herb Danshen), and is widely used to treat atherosclerosis. The pregnane X receptor (PXR) is a nuclear receptor that is a key regulator of xenobiotic and endobiotic detoxification. Tan IIA is an efficacious PXR agonist that has a potential protective effect on endothelial injuries induced by xenobiotics and endobiotics via PXR activation. Previously numerous studies have demonstrated the possible effects of Tan IIA on human umbilical vein endothelial cells, but the further mechanism for its exerts the protective effect is not well established. To study the protective effects of Tan IIA against hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) in human umbilical vein endothelial cells (HUVECs), we pretreated cells with or without different concentrations of Tan IIA for 24 h, then exposed the cells to 400 μM H<sub>2</sub>O<sub>2</sub> for another 3 h. Therefore, our data strongly suggests that Tan IIA may lead to increased regeneration of glutathione (GSH) from the glutathione disulfide (GSSG) produced during the GSH peroxidase-catalyzed decomposition of H<sub>2</sub>O<sub>2</sub> in HUVECs, and the PXR plays a significant role in this process. Tan IIA may also exert protective effects against H<sub>2</sub>O<sub>2</sub>-induced apoptosis through the mitochondrial apoptosis pathway associated with the participation of PXR. Tan IIA protected HUVECs from inflammatory mediators triggered by H<sub>2</sub>O<sub>2</sub> via PXR activation. In conclusion, Tan IIA protected HUVECs against H<sub>2</sub>O<sub>2</sub>-induced cell injury through PXR-dependent mechanisms.

To study the protective effects of Tan IIA against hydrogen peroxide ($H_2O_2$) in human umbilical vein endothelial cells (HUVECs), we pretreated cells with or without different concentrations of Tan IIA for 24 h, then exposed the cells to $400{\mu}M$ $H_2O_2$ for another 3 h.

        Surface plasmon resonance-enhanced solar-driven photocatalytic performance from Ag nanoparticles-decorated Ti3+ self-doped porous black TiO2 pillars

        Guo Zhou,Haiyan Meng,Yan Cao,Xuejun Kou,Shuxiang Duan,Leilei Fan,Ming Xiao,Fangzhou Zhou,Zhenzi Li,Zipeng Xing 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.64 No.-

        The tiny Ag nanoparticles-uniformly decorated Ti3+ self-doped porous black TiO2 pillars (Ag-TPBTPs) are prepared, which show obvious surface plasmon resonance (SPR) and extend the photoresponse to visible light and near-infrared region (∼1500 nm). The Ag-TPBTPs exhibit excellent solar-driven photocatalytic activities by mineralizing of high-toxic 2,4-dichlorophenol (∼99%), which is three times higher than that of the pristine TiO2. The remarkable solar-driven photocatalytic performance can be ascribed to the porous pillars structure offering more surface active sites, the self-doped Ti3+ and SPR effect of Ag nanoparticles improving the utilization of solar light, and enhancing the spatial separation efficiency of photogenerated charge carriers.

        Kun Yan,Haiyan Zhou,Hailin Xiao,Xiangli Zhang 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

        With the flourishing of wireless information access, indoor positioning is becoming a topic of interest in both academic and industry community. Numerous techniques have been proposed to address this problem under diverse circumstances. Recently, the area of indoor positioning is dominated by three kinds of methodologies, such as rangebased positioning, fingerprint-based positioning and inertial positioning. This paper is presented to overview the indoor positioning techniques using visible light based on the range-based positioning. The state-of-the-art research results will be studied. The typical localization mechanisms used in visible light positioning systems are analyzed by evaluation metrics to provide an insight of the systems’ performances.

        Differences in Phase Change Processes Upon Heating Between Co and Zn-ZIF-4 Compounds

        Kaihui Li,Haiyan Xiao,Jianxiong He,Hong Jiang 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2018 NANO Vol.13 No.3

        Zn and Co-ZIF-4 meta-stable compounds adopt the same topology of Zeolitic imidazolate frameworks (ZIF)-4, but differ in the metal nodes (Zn versus Co). Using calorimetric and thermogravimetric analysis, here we characterized their differences in phase change processes. Upon heating, the framework of Co-ZIF-4 meta-stable crystal undergoes the crystal-to-amorphous phase transition at 590 K, which is somewhat lower than the corresponding transition previously reported in the corresponding Zn-ZIF-4. In addition, the recrystallization rate for amorphous Co-ZIF-4 is relatively higher than the corresponding one of Zn-ZIF-4. Finally, the forming Co–zni crystal begins to melt at about 824K, accompanied by quick decomposition, whereas Zn–zni undergoes complete melting which finishes at around 850K without any decomposition. Based on their differences in chemistry for Co and Zn, we elucidated the chemical origin of the discrepancies of phase transition process for Zn and Co-ZIF-4 compounds upon heating.

        Behavior of three-tube buckling-restrained brace with circumference pre-stress in core tube

        Yang Li,Haiyan Qu,Shaowen Xiao,Peijun Wang,Yang You,Shuqing Hu 국제구조공학회 2019 Steel and Composite Structures, An International J Vol.30 No.2

        The behavior of a new Three-Tube Buckling-Restrained Brace (TTBRB) with circumference pre-stress (σθ,pre) in core tube are investigated through a verified finite element model. The TTBRB is composed of one core tube and two restraining tubes. The core tube is in the middle to provide the axial stiffness, to carry the axial load and to dissipate the earthquake energy. The two restraining tubes are at inside and outside of the core tube, respectively, to restrain the global and local buckling of the core tube. Based on the yield criteria of fringe fiber, a design method for restraining tubes is proposed. The applicability of the proposed design equations are verified by TTBRBs with different radius-thickness ratios, with different gap widths between core tube and restraining tubs, and with different levels of σθ,pre. The outer and inner tubes will restrain the deformation of the core tube in radius direction, which causes circumference stress (σθ) in the core tube. Together with the σθ,pre in the core tube that is applied through interference fit of the three tubes, the yield strength of the core tube in the axial direction is improved from 160 MPa to 235 MPa. Effects of gap width between the core tube and restraining tubes, and σθ,pre on hysteretic behavior of TTBRBs are presented. Analysis results showed that the gap width and the σθ,pre can significantly affect the hysteretic behavior of a TTBRB.
