| 1 | Mutual effects of nitric oxide and iron on the growth of marine algae显示文摘Experiments on the effects of nitric oxide (NO) and iron on the growth of marine microalgae Skeletonema costatum were conducted. The results are as follows: exogenous NO could increase the growth rate of marine algae and raise the biomass remarkably under iron-deficient conditions. But it was a complicated process that the phytoplankton growth was influenced by NO and iron, which was controlled by the NO concentration, the nutrition level of the culture medium and the iron concentration, etc. Meanwhile, the iron concentration in the medium also has a direct influence on the growth and NO release capacity of the algae. Therefore, the effects of NO and iron on the growth of marine phytoplankton were mutual. | LIU Chunying ZHANG Zhengbin CHEN Xiaorui | 2005 | Acta Oceanologica Sinica2005，24，5： | 11 |
| 2 | ZrO2/PMMA Nanocomposites: Preparation and Its Dispersion in Polymer Matrix显示文摘ZrO2/PMMA nanocomposite particles are synthesized through an in-situ free radical emulsion polymerization based on the silane coupling agent (Z-6030) modified ZrO2 nanoparticles, and the morphology, size and its distribution of nanocomposite particles are investigated. Scanning electron microscopy (SEM) images demonstrate that the methyl methacrylate (MMA) feeding rate has a significant effect on the particle size and morphology. When the MMA feeding rate decreases from 0.42ml·min-1 to 0.08ml·min-1 , large particles (about 200-550nm) will not form, and the size distribution become narrow (36-54nm). The average nanocomposite particles size increases from 34nm to 55nm, as the MMA/ZrO2 nanoparticles mass ratio increased from 4:1 to 16:1. Regular spherical ZrO2/PMMA nanocomposite particles are synthesized when the emulsifier OP-10 concentration is 2mg·ml-1. The nanocomposite particles could be mixed with VAc-VeoVa10 polymer matrix just by magnetic stirring to prepare the ZrO2 /PMMA/VAc-VeoVa10 hybrid coatings. SEM and atomic force microscopy (AFM) photos reveal that the distribution of the ZrO2 /PMMA nanocomposite particles in the VAc-VeoVa10 polymer matrix is homogenous and stable. Here, the grafted-PMMA polymer on ZrO2 nanoparticles plays as a bridge which effectively connects the ZrO2 nanoparticles and the VAc-VeoVa10 polymer matrix with improved comparability. In consequence, the hybrid coating with good dispersion stability is obtained. | FAN Fangqiang XIA Zhengbin LI Qingying LI Zhong CHEN Huanqin | 2013 | Chinese Journal of Chemical Engineering2013，21，2： | 4 |

| 4 | Effect of aging treatment on microstructure and corrosion behavior of a Fe-18Cr-15Mn-0.66N stainless steel显示文摘The effect of aging treatment on the microstructure and corrosion behavior of a Fe-18Cr-15Mn-0.66N high-nitrogen stainless steel(HNSS) in 3.5 wt.% Na Cl solution was investigated using a series of electrochemical tests, scanning electronic microscopy(SEM), X-ray diffraction(XRD) and X-ray photoelectron spectroscopy(XPS). The results showed that the aging treatment led to the precipitation of CrN particles along the grain boundaries and their morphologies changed from dispersive particles to continuous network as the aging time increased up to 60 min. Aging time had minor effects on the corrosion potential and corrosion current density, but resulted in the sharp decrease in the pitting corrosion potential.The passive film behaved as a n-type semiconductor, and the donor density of the passive film increased with the aging time. Meanwhile, the fraction of stable oxide(CrO) in the passive film decreased with the aging time. It demonstrates that the aging treatment deteriorated the protectiveness of the passive film, hence weakened the corrosion resistance of HNSS. | Yanxin Qiao Xinyi Wang Lanlan Yang Xiaojing Wang Jian Chen Zhengbin Wang Huiling Zhou Jiasheng Zou Fuhui Wang | 2022 | Journal of Materials Science & Technology2022，，12： | 3 |
| 5 | Shortening the sgRNA-DNA interface enables SpCas9 and eSpCas9(1.1)to nick the target DNA strand显示文摘The length of the sgRNA-DNA complementary sequence is a key factor influencing the cleavage activity of Streptococcus pyogenes Cas9(SpCas9)and its variants.The detailed mechanism remains unknown.Here,based on in vitro cleavage assays and base editing analysis,we demonstrate that reducing the length of this complementary region can confer nickase activity on SpCas9 and eSpCas9(1.1).We also show that these nicks are made on the target DNA strand.These properties encouraged us to develop a dual-functional system that simultaneously carries out double-strand DNA cleavage and C-to-T base conversions at separate targets.This system provides a novel tool for achieving trait stacking in plants. | Rong Fan Zhuangzhuang Chai Sinian Xing Kunling Chen Fengti Qiu Tuanyao Chai Jin-Long Qiu Zhengbin Zhang Huawei Zhang Caixia Gao | 2020 | Science China(Life Sciences)2020，63，11： | 2 |

| 7 | Weakly-coupled mode division multiplexing over conventional multi-mode fiber with intensity modulation and direct detection显示文摘Multi-mode fiber(MMF)links are expected to greatly enhance capacity to cope with rapidly increasing data traffic in optical short-reach systems and networks.Recently,mode division multiplexing(MDM)over MMF has been proposed,in which different modes in MMF are utilized as spatial channels for data transmission.Stronglycoupled MDM techniques utilizing coherent detection and multiplex-input-multiplex-output(MIMO)digital signal processing(DSP)are complex and expensive for shortreach transmission.So the weakly-coupled approach by significantly suppressing mode coupling in the fiber and optical components has been proposed.In this way,the signals in each mode can be independently transmitted and received using conventional intensity modulation and direct detection(IM-DD).In this paper,we elaborate the key technologies to realize weakly-coupled MDM transmission over conventional MMF,including mode characteristic in MMF and weakly-coupled mode multiplexer/ demultiplexer(MUX/DEMUX).We also present the upto-date experimental results for weakly-coupled MDM transmission over conventional OM3 MMF.We show that weakly-coupled MDM scheme is promising for high-speed optical interconnections and bandwidth upgrade of already-deployed MMF links. | Juhao LI Zhongying WU Dawei GE Jinglong ZHU Yu TIAN Yichi ZHANG Jinyi YU Zhengbin LI Zhangyuan CHEN Yongqi HE | 2019 | Frontiers of Optoelectronics2019，12，1： | 1 |

| 12 | Identification of oleic acid as an endogenous ligand of GPR3显示文摘Although GPR3 plays pivotal roles in both the nervous system and metabolic processes,such as cold-induced thermogenesis,its endogenous ligand remains elusive.Here,by combining structural approach(including cryo-electron microscopy),mass spectrometry analysis,and functional studies,we identify oleic acid(OA)as an endogenous ligand of GPR3.Our study reveals a hydrophobic tunnel within GPR3 that connects the extracellular side of the receptor to the middle of plasma membrane,enabling fatty acids to readily engage the receptor.Functional studies demonstrate that OA triggers downstream Gs signaling,whereas lysophospholipids fail to activate the receptor.Moreover,our research reveals that cold stimulation induces the secretion of OA in mice,subsequently activating Gs/cAMP/PKA signaling in brown adipose tissue.Notably,brown adipose tissues from Gpr3 knockout mice do not respond to OA during cold stimulation,reinforcing the significance of GPR3 in this process.Finally,we propose a“born to be activated and cold to enhance”model for GPR3 activation.Our study provides a starting framework for the understanding of GPR3 signaling in cold-stimulated thermogenesis. | Yangjie Xiong Zhenmei Xu Xinzhi Li Yuqin Wang Jing Zhao Na Wang Yaning Duan Ruixue Xia Zhengbin Han Yu Qian Jiale Liang Anqi Zhang Changyou Guo Asuka Inoue Yu Xia Zheng Chen Yuanzheng He | 2024 | Cell Research2024，34，3： | 0 |
| 13 | Flavanone and flavonoid hydroxylase genes regulate fiber color formation in naturally colored cotton显示文摘Using naturally colored cotton(NCC)can eliminate dyeing,printing and industrial processing,and reduce sewage discharge and energy consumption.Proanthocyanidins(PAs),the primary coloration components in brown fibers,are polyphenols formed by oligomers or polymers of flavan-3-ol units derived from anthocyanidins.Three essential structural genes for flavanone and flavonoid hydroxylation encoding flavanone-3-hydroxylase(F3H),flavonoid 3’-hydroxylase(F3’H)and flavonoid 3’5’-hydroxylase(F3’5’H)are initially committed in the flavonoid biosynthesis pathway to produce common precursors.The three genes were all expressed predominantly in developing fibers of NCCs,and their expression patterns varied temporally and spatially among NCC varieties.In GhF3Hi,GhF3’Hi and GhF3’5’Hi silenced lines of NCC varieties XC20 and ZX1,the expression level of the three genes decreased in developing cotton fiber,negatively correlated with anthocyanidin content and fiber color depth.Fiber color depth and type in RNAi lines changed with endogenous gene silencing efficiency and expression pattern,the three hydroxylase genes functioned in fiber color formation.GhF3H showed functional differentiation among NCC varieties and GhF3’H acted in the accumulation of anthocyanin in fiber.Compared with GhF3’H,GhF3’5’H was expressed more highly in brown fiber with a longer duration of expression and caused lighter color of fibers in GhF3’5’H silenced lines.These three genes regulating fiber color depth and type could be used to improve these traits by genetic manipulation. | Hongli Zheng Bailin Duan Bo Yuan Zhengbin Chen Dongliang Yu Liping Ke Wenlong Zhou Haifeng Liu Yuqiang Sun | 2023 | The Crop Journal2023，11，3： | 0 |

| 16 | Successful kidney transplantation in highly sensitized patients显示文摘Highly sensitized patients experience an increased number of rejection episodes and have poorer graft survival rates;hence,sensitization is a significant barrier to both access to and the success of organ transplantation.This study reports our experience in kidney transplantation in highly sensitized patients.Fourteen patients with sensitization or high levels of panelreactive antibodies(PRA)were studied.All patients were desensitized with pre-transplant intravenous immunoglobulin(IVIG)/plasmapheresis(PP)with or without rituximab and thymoglobulin induction therapy,combined with a Prograf/MMF/Pred immunosuppressive regimen.Of 14 patients,10 showed good graft functions without acute rejection(AR)episodes.Acute cellular rejection in two patients was reversed by methylprednisolone.Two patients underwent antibody-mediated rejection;one was treated with PP/IVIG successfully,whereas the other lost graft functions due to the de novo production of donor-specific antibodies(DSA).Graft functions were stable,and there were no AR episodes in other patients.Conclusively,desensitization using PP/IVIG with or without rituximab increases the likelihood of successful live-donor kidney transplantation in sensitized recipients. | Weijie ZHANG Dong CHEN Zhishui CHEN Fanjun ZENG Changsheng MING Zhengbin LIN Ping ZHOU Gang CHEN Xiaoping CHEN | 2011 | Frontiers of Medicine2011，5，1： | 0 |
