| 1 | VdPKS1 is required for melanin formation and virulence in a cotton wilt pathogen Verticillium dahliae显示文摘Verticillium dahliae is a soil-borne phytopathogenic fungus that causes vascular wilt disease in a broad range of hosts.This pathogen survives for many years in soil in the form of melanized microsclerotia.To investigate the melanin synthesis in V.dahliae,we identified a polyketide synthase gene in V.dahliae,namely VdPKS1.PKS1 is known to involve in the dihydroxynaphthalene melanin synthesis pathway in many fungi.We found that VdPKS1 was required for melanin formation but not for microsclerotial production in V dahliae.The VdPKS1 gene-disruption mutant (vdpksl) formed melanin-deficient albino microsclerotia,which did not affect the fungal colonization in host tissues but significantly reduced the disease severity.Gene transcription analysis in the wild-type and the vdpksl strains suggested that VdPKS1 gene-disruption influenced the expression of a series of genes involved in ethylene biosynthesis,microsclerotial formation and pathogenesis.Our results suggest that the VdPKS1-mediated melanin synthesis is important for virulence and developmental traits of V.dahliae. | Ting Zhang Bosen Zhang Chenlei Hua Pei Meng Sheng Wang Zhirong Chen Yejuan Du Feng Gao Jiafeng Huang | 2017 | Science China(Life Sciences)2017，60，8： | 14 |
| 2 | Identification of the surgical indication line for the Denonvilliers’fascia and its anatomy in patients with rectal cancer显示文摘Background:The high rate of urogenital dysfunction after traditional total mesorectal excision(TME)has caused doubts among scholars on the standard fashion of dissection.We have proposed the necessity to preserve the Denonvilliers’fascia in patients with rectal cancer.However,how to accurately locate the Denonvilliers’fascia is unclear.This study aimed to explore anatomical features of the Denonvilliers’fascia by comparing autopsy findings and observations of surgical videos so as to propose a dissection method for the preservation of pelvic autonomic nerves during rectal cancer surgery.Methods:Five adult male cadaver specimens were dissected,and surgical videos of 135 patients who underwent TME for mid-low rectal cancer between January 2009 and February 2019 were reviewed to identify and compare the structure of the Denonvilliers’fascia.Results:The monolayer structure of the Denonvilliers’fascia was observed in 5 male cadaver specimens,and it was located between the rectum,the bottom of the bladder,the seminal vesicles,the vas deferens,and the prostate.The Denonvilliers’fascia was originated from the rectovesical pouch(or rectum-uterus pouch),down to fuse caudally with the rectourethral muscle at the apex of the prostate,and fused to the lateral ligaments on both sides.The fascia was thinner on the midline with a thickness of 1.06±0.10 mm.The crown shape of the Denonvilliers’fascia was slightly triangular,with a height of approximately 5.42±0.16 cm at midline.Nerves were more densely distributed in front of the Denonvilliers’fascia than behind,especially on both sides of it.Under laparoscopic view,the Denonvilliers’fascia was originated at the lowest point of the rectovesical pouch(or rectum-uterus pouch),with a thickened white line which was a good mark for identifying the Denonvilliers’fascia.Conclusion:Identification of the surgical indication line for the Denonvilliers’fascia could help us identify the Denonvilliers’fascia,and it would improve our ability to protect the pelvic autonomic function of patients undergoing TME for rectal cancer. | Jianglong Huang Jing Liu Jiafeng Fang Zongheng Zeng Bo Wei Tufeng Chen Hongbo Wei | 2020 | Cancer Communications2020，40，1： | 10 |
| 3 | Identification of QTL and candidate genes involved in early seedling growth in rice via high-density genetic mapping and RNA-seq显示文摘Early seedling vigor(ESV)is a major breeding target in rice,especially under direct seeding.To identify quantitative trait locus(QTL)affecting ESV,a recombinant inbred line population derived from a cross between 02428 and YZX,two cultivars differing in vigor during early seedling growth,was used for QTL analysis.Nine traits associated with ESV were examined using a high-density map.Of 16 additive loci identified,three were detected in two generations and thus considered stable.Four epistatic interactions were detected,one of which was repeated in two generations.Further analysis of the pyramiding effect of the three stable QTL showed that the phenotypic value could be effectively improved with an increasing number of QTL.These results were combined with results from our previous QTL analysis of the germination index.The lines G58 and G182 combined all the favourable alleles of all three stable QTL for ESV and three QTL for germination speed.These two lines showed rapid germination and strong ESV.A total of 37 candidate differentially expressed genes were obtained from the regions of the three stable QTL by analysis of the dynamic transcriptomic expression profile during the seedling growth period of the two parents.The QTL are targets for ESV breeding and the candidate genes await functional validation.This study provides a theoretical basis and a genetic resource for the breeding of directseeded rice. | Jing Yang Zhenhua Guo Lixin Luo Qiaoli Gao Wuming Xiao Jiafeng Wang Hui Wang Zhiqiang Chen Tao Guo | 2021 | The Crop Journal2021，9，2： | 6 |
| 4 | The Class Ⅲ peroxidase gene OsPrx30,transcriptionally modulated by the AT-hook protein OsATH1, mediates rice bacterial blight-induced ROS accumulation显示文摘Class Ⅲ peroxidases(CⅢ Prxs) play critical roles in plant immunity by scavenging reactive oxygen species(ROS). However, the functions of CⅢ Prxs in rice(Oryza sativa L.) immunity are largely unexplored. Here, we report a Prx precursor, OsPrx30,that is responsive to the bacterial blight Xanthomonas oryzae pv. oryzae(Xoo). OsPrx30 was primarily expressed in rice roots, leaves, and stems,and its protein product was mainly localized at the endoplasmic reticulum. Overexpression of OsPrx30 enhanced the plant’s susceptibility to Xoo by maintaining a high level of peroxidase(POD) activity and reducing the content of H2O2, whereas depletion of OsPrx30 had the opposite effects. Furthermore, we identified an AT-hook transcription factor, Os ATH1, that is specifically bound to the OsPrx30 promoter. As observed in plants overexpressing OsPrx30, depletion of Os ATH1 enhanced susceptibility to Xoo. Finally, we demonstrated that depletion of Os ATH1 increased histone H3 acetylation at the AT-rich region of the OsPrx30 promoter.Taken together, these results reveal a mechanism underlying the POD-induced natural resistance to bacterial diseases and suggest a model for transcription regulation of Prx genes in rice. | Hao Liu Shuangyu Dong Ming Li Fengwei Gu Guili Yang Tao Guo Zhiqiang Chen Jiafeng Wang | 2021 | Journal of Integrative Plant Biology2021，63，2： | 2 |
| 5 | Surface modification with oxygen vacancy in Li-rich layered oxide Li1.2Mn0.54Ni0.13Co0.13O2 for lithium-ion batteries显示文摘A couple of layered Li-rich cathode materials Li1.2Mn0.54Ni0.13Co0.13O2 without any carbon modification are successfully synthesized by solvothermal and hydrothermal methods followed by a calcination process. The sample synthesized by the solvothermal method(S-NCM) possesses more homogenous microstructure, lower cation mixing degree and more oxygen vacancies on the surface, compared to the sample prepared by the hydrothermal method(H-NCM). The S-NCM sample exhibits much better cycling performance, higher discharge capacity and more excellent rate performance than H-NCM. At 0.2 C rate,the S-NCM sample delivers a much higher initial discharge capacity of 292.3 mAh g^-1 and the capacity maintains 235 m Ah g^-1 after 150 cycles(80.4% retention), whereas the corresponding capacity values are only 269.2 and 108.5 m Ah g^-1(40.3% retention) for the H-NCM sample. The S-NCM sample also shows the higher rate performance with discharge capacity of 118.3 mAh g^-1 even at a high rate of 10 C, superior to that(46.5 m Ah g^-1) of the H-NCM sample. The superior electrochemical performance of the S-NCM sample can be ascribed to its well-ordered structure, much larger specific surface area and much more oxygen vacancies located on the surface. | Bozhou Chen Bangchuan Zhao Jiafeng Zhou Zhitang Fang Yanan Huang Xuebin Zhu Yuping Sun | 2019 | Journal of Materials Science & Technology2019，35，6： | 2 |

| 9 | Mechanisms of rotenone-induced neurotoxicity in PC 12 cells显示文摘BACKGROUND: Rotenone-induced neurotoxicity in PC 12 cells has been widely used to study the pathogenesis of Parkinson's disease. However, the precise mechanisms underlying rotenone-induced dopaminergic neuronal degeneration in Parkinson's disease remains unclear. OBJECTIVE: To establish rotenone-induced neurotoxicity in PC 12 cells, and to investigate the possible action pathways to rotenone-induced neural cell injury at the protein level. DESIGN, TIME AND SETTING: A controlled proteomics study was performed at the Department of Neurology, First Hospital, Jilin University between March 2006 and March 2007. MATERIALS: PC 12 cells were obtained from Shanghai Cell Bank of Chinese Academy of Sciences, China. Rotenone was provided by Sigma, USA. METHODS: PC 12 cells in logarithmic growth phase were treated under experimental and control conditions, respectively. A total of 0.5 μmol/L rotenone, or the same amount of Dulbecco’s modified eagle’s medium (DMEM), was added in the experimental and control conditions, respectively. MAIN OUTCOME MEASURES: Following 72 hours of rotenone treatment, cellular survival rate was determined by methyl thiazolyl tetrazolium assay, and apoptotic changes were detected by Hoechst 33342 staining. Total cellular protein was extracted to acquire differential protein expression data utilizing two-dimensional differential in-gel electrophoresis. To identify differential protein spots, matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF-MS) was used. RESULTS: In the MTT assay, the experimental condition induced significantly less cell survival compared to the control condition (P < 0.01). Hoechst 33342 staining revealed a larger number of apoptotic cells under the experimental condition compared to the control condition (P < 0.01), as determined by the presence of nuclear condensation, pyknosis, and nuclear fragmentation. Two-dimensional electrophoresis results showed that the differential expression of protein spots 1069 and 1538 was increased by 144% and 124%, respectively, while that of protein spot 1094 was decreased by 123% in the experimental condition compared to the control condition (P < 0.01). By MALDI-TOF-MS analysis and database retrieval, γ-enolase, triosephosphate isomerase 1, and eukaryotic translation initiation factor 4A were confirmed to be involved in rotenone-induced neural cell injury. CONCLUSION: γ-enolase, triosephosphate isomerase 1, and eukaryotic translation initiation factor 4A might participate in rotenone-induced neurotoxicity in PC 12 cells. | Wei Han Lizhong Sun Jiafeng Chen Ming Chang Hongyan Huo Linsen Hu | 2008 | Neural Regeneration Research2008，3，12： | 1 |
| 10 | Experiments and insights of desalination by a freezing/thawing method at low subcooling显示文摘Desalination by freezing/thawing method was a very important method to obtain fresh water from seawater.In this work,desalination by freezing/thawing method was conducted with initial sodium chloride of 3.5 wt% in consideration of stirring speed,freezing time and subcooling.The subcooling ranged from 1.2 K to 4 K.The optimum conditions for desalination in this work were stirring speed of 200 r·min^−1,freezing time of 120 min,and subcooling of 3 K.The results also showed that sodiumchloride cannot be effectively removed by once freezing/thawing process.The maximumremoval efficiency of sodiumchloride was 64.3%.Two major reasons resulting in the impurity of obtained melted water by freezing/thawing method were proposed.The first reason was the inevitable adhesion of salt solution to the surface of ice,which could be removed easily by distilled water flushing.The second reason was that salt solution was heterogeneously wrapped in the accumulated ice,which was difficult to be removed by distilled water flushing.The liquid flushing method was proposed to verify the conjecture,and the results were in accordance with the two reasons mentioned above.Additional method,such as multiple flushing liquid method,was suggested to be used during the freezing/thawing process for effectively removing sodium chloride,and obtaining fresh water. | Jun Chen Jianjian Wu Jiafeng Xu Qing Yuan Bin Deng Changzhong Chen Zhi Li | 2020 | Chinese Journal of Chemical Engineering2020，28，12： | 1 |
| 11 | Nonlinear electronic and ultrafast optical signatures in chemical vapor-deposited ultrathin PtS_(2) ribbons显示文摘The emerging two-dimensional(2D)platinum disulfide(PtS_(2))has driven increasing attentions due to its high electron mobility,good air-stability,and strong interlayer interaction which leads to a widely tunable electronic structure.However,a detailed study on its covalent-like layer-dependent properties remains infant.Herein,we demonstrate the successful production of ultrathin 1T-PtS_(2) ribbons with thickness centralized almost at monolayer 1L-4L and large domain size up to 210 μm on Au foils using chemical vapor deposition(CVD)technique,which enables macro-and microscopic study of its extraordinary layer-dependent features with precise control of the number of layers.Using electron energy loss spectroscopy(EELS)and optical pump-probe spectroscopy(OPPS),we reveal that both the electron and ultrafast optical absorption signals of the as-grown 2D PtS_(2) show strong nonlinear layer-dependent responses which manifest discriminated transition in 1L-4L PtS_(2) ribbons.The layer-dependent nonlinear response of 2D PtS_(2) can be well interpreted in the frame of calculated electron and phonon structures.These achievements offer a platform for successfully fabricating large-sized ultrathin 2D PtS_(2) and facilitating our knowledge about its electronic and optoelectronic properties. | Shaolong Jiang Jin Yang Liang Zhu Jiafeng Xie Weiteng Guo Erding Zhao Chaoyu Chen Tianwu Wang Fuhai Su Yanfeng Zhang Junhao Lin | 2022 | Nano Research2022，15，5： | 1 |

| 13 | Growth of BiOBr/ZIF‑67 Nanocomposites on Carbon Fiber Cloth as Filter‑Membrane‑Shaped Photocatalyst for Degrading Pollutants in Flowing Wastewater显示文摘BiOBr-based nanocomposite photocatalysts are used for removing the organic pollutants,but their poor adsorption/photocatalytic performances and the low potential for recycling limit their application.To solve the issue,herein we report a large-area recyclable CFC/BiOBr/ZIF-67 filter-membrane-shaped photocatalyst prepared by in situ growth of BiOBr/ZIF-67 nanocomposites on carbon fiber cloth(CFC).Fabrication process is based on hydrothermal synthesis of BiOBr nanosheets(diameter 0.5–1μm)on carbon fiber cloth(as substrate material)and then a chemical bath route is used to grow ZIF-67 nanoparticles(diameter 300–600 nm)in situ on the surface of CFC/BiOBr.Resulted composite,CFC/BiOBr/ZIF-67,exhibits a high specific surface area(545.82 m^(2) g^(−1))and a wide photoabsorption,accompanied by an absorption edge(~620 nm).In dark condition,CFC/BiOBr/ZIF-67 adsorbs bisphenol A(BPA)and orange 7(AO7)within 60 min,respectively with 20.0% and 40.1% efficiency.This level of efficiencies are correspondingly 2.6 and 3.2 times more that of the bare CFC/BiOBr(7.6%for BPA and 12.4% for AO7).Under visible light irradiation,CFC/BiOBr/ZIF-67 can degrade 69.7% of BPA and 96.0% of AO7,in 120 min,which are,respectively,1.3 and 1.8 times higher than the absorption efficiency of bare CFC/BiOBr(53.2% for BPA,52.0% for AO7).When CFC/BiOBr/ZIF-67 is used as a filter membrane for photocatalytic removal of pollutants in flowing wastewater(AO7,rate:~1.5 L h^(−1)),92.2%of AO7 can be decomposed after 10 filtering cycles.This study suggests CFC/BiOBr/ZIF-67 as a novel highly functional,recyclable and environmental friendly photo-driven membrane filter for purification and recovery of flowing surface waste waters. | Xiaolong Li Ting Liu Yan Zhang Jiafeng Cai Mengqiang He Maoquan Li Zhigang Chen Lisha Zhang | 2022 | Advanced Fiber Materials2022，4，6： | 1 |

| 16 | Urban growth scenario projection using heuristic cellular automata in arid areas considering the drought impact显示文摘Arid areas with low precipitation and sparse vegetation typically yield compact urban pattern,and drought directly impacts urban site selection,growth processes,and future scenarios.Spatial simulation and projection based on cellular automata(CA)models is important to achieve sustainable urban development in arid areas.We developed a new CA model using bat algorithm(BA)named bat algorithm-probability-of-occurrence-cellular automata(BA-POO-CA)model by considering drought constraint to accurately delineate urban growth patterns and project future scenarios of Urumqi City and its surrounding areas,located in Xinjiang Uygur Autonomous Region,China.We calibrated the BA-POO-CA model for the drought-prone study area with 2000 and 2010 data and validated the model with 2010 and 2020 data,and finally projected its urban scenarios in 2030.The results showed that BA-POO-CA model yielded overall accuracy of 97.70%and figure-of-merits(FOMs)of 35.50%in 2010,and 97.70%and 26.70%in 2020,respectively.The inclusion of drought intensity factor improved the performance of BA-POO-CA model in terms of FOMs,with increases of 5.50%in 2010 and 7.90%in 2020 than the model excluding drought intensity factor.This suggested that the urban growth of Urumqi City was affected by drought,and therefore taking drought intensity factor into account would contribute to simulation accuracy.The BA-POO-CA model including drought intensity factor was used to project two possible scenarios(i.e.,business-as-usual(BAU)scenario and ecological scenario)in 2030.In the BAU scenario,the urban growth dominated mainly in urban fringe areas,especially in the northern part of Toutunhe District,Xinshi District,and Midong District.Using exceptional and extreme drought areas as a spatial constraint,the urban growth was mainly concentrated in the'main urban areas-Changji-Hutubi'corridor urban pattern in the ecological scenario.The results of this research can help to adjust urban planning and development policies.Our model is readily applicable to simulating urban growth and future scenarios in global arid areas such as Northwest China and Africa. | TANG Xiaoyan FENG Yongjiu LEI Zhenkun CHEN Shurui WANG Jiafeng WANG Rong TANG Panli WANG Mian JIN Yanmin TONG Xiaohua | 2024 | Journal of Arid Land2024，16，4： | 0 |
| 17 | Experimental Study on Cloud-Computing-Based Electric Power SCADA System显示文摘With the development of smart grid,the electric power supervisory control and data acquisition(SCADA) system is limited by the traditional IT infrastructure,leading to low resource utilization and poor scalability.Information islands are formed due to poor system interoperability.The development of innovative applications is limited,and the launching period of new businesses is long.Management costs and risks increase,and equipment utilization declines.To address these issues,a professional private cloud solution is introduced to integrate the electric power SCADA system,and conduct experimental study of its applicability,reliability,security,and real time.The experimental results show that the professional private cloud solution is technical and commercial feasible,meeting the requirements of the electric power SCADA system. | Yongbo Chen Jijun Chen Jiafeng Gan | 2015 | ZTE Communications2015，13，3： | 0 |
| 18 | Ionospheric disturbance analysis of the January 15,2022 Tonga eruption based on GPS data显示文摘Hunga Tonga-Hunga Ha’apai climactic eruption on January 15,2022,released enormous energy that affected the ionosphere over the Pacific Rim.We analyzed ionospheric disturbance following volcanic eruptions using near-field(<1000 km),regional(1000–5000 km),and far-field(5000–12000 km) global positioning system(GPS) observations.The results indicate that the near-field ionospheric perturbation that occurred 8–15 min after the cataclysmic eruption was mainly derived from the shock wave(~1000 m/s) generated by the blast,while the low-frequency branch with long-distance propagation characteristics over the regional and the far-field was mainly associated with atmospheric Lamb waves(~330 m/s).Moreover,the amplitude of disturbance and background total electron content(TEC) are related proportionally.The intensity of the volcanic eruption and the background ionospheric conditions determine the magnitude of ionospheric responses.TEC perturbations were invisible on the reference days.Furthermore,the source location and onset time were calculated using the ray tracing technique,which confirms that the Tonga event triggered the ionospheric anomaly beyond the crater.Finally,the change in the frequency of the perturbations coincided with the arrival of the initial tsunami,implying the generation of a meteotsunami. | Jiafeng LI Kejie CHEN Haishan CHAI Jian LIN Zhiyuan ZHOU Hai ZHU Mingzhe LYU | 2023 | Science China Earth Sciences2023，66，8： | 0 |
| 19 | YTHDF2-mediated regulations bifurcate BHPF-induced programmed cell deaths显示文摘N6-methyladenosine(m^(6)A)is a critical regulator in the fate of RNA,but whether and how m^(6)A executes its functions in different tissues remains largely obscure.Here we report downregulation of a crucial m^(6)A reader,YTHDF2,leading to tissue-specific programmed cell deaths(PCDs)upon fluorene-9-bisphenol(BHPF)exposure.Currently,Bisphenol A(BPA)substitutes are widely used in plastic manufacturing.Interrogating eight common BPA substitutes,we detected BHPF in 14%serum samples of pregnant participants.In a zebrafish model,BHPF caused tissue-specific PCDs triggering cardiac and vascular defects.Mechanistically,BHPF-mediated downregulation of YTHDF2 reduced YTHDF2-facilitated translation of m^(6)A-gch1 for cardiomyocyte ferroptosis,and decreased YTHDF2-mediated m^(6)A-sting1 decay for caudal vein plexus(CVP)apoptosis.The two distinct YTHDF2-mediated m^(6)A regulations and context-dependent co-expression patterns of gch1/ythdf2 and tnfrsf1a/ythdf2 contributed to YTHDF2-mediated tissue-specific PCDs,uncovering a new layer of PCD regulation.Since BHPF/YTHDF2-medaited PCD defects were also observed in mammals,BHPF exposure represents a potential health threat. | Jiebo Lin Guankai Zhan Jinfeng Liu Yasen Maimaitiyiming Zhiping Deng Baohua Li Kunhui Su Jiafeng Chen Siqi Sun Wanlin Zheng Xianghui Yu Feng He Xiaodong Cheng Lingfang Wang Bin Shen Ziqin Yao Xinquan Yang Jian Zhang Wentao He Hengyu Wu Hua Naranmandura Kao-Jung Chang Junxia Min Jun Ma Mikael Björklund Peng-Fei Xu Fudi Wang Chih-Hung Hsu | 2023 | National Science Review2023，10，12： | 0 |
| 20 | Partial overlapping channels are not damaging显示文摘We know that in many different technologies, many wireless channels will be partially overlapped. However, due to the interference eff ects in such partial overlapping channels, they are often avoided using them simultaneously. In this paper, we propose to use the method of the system for the fi rst time to try to simulate some overlap between channels. Through this model, we show that the use of partially overlapping channels is not always harmful. In fact, if careful use of some of the overlapping channels often leads to signifi cant improvements in spectrum utilization and application performance. We demonstrate this view through analysis, as well as through detailed application layer and MAC layer measurements. In addition, we illustrate the benefi ts of the model we developed by using it to directly enhance the performance of two previously proposed channel allocation algorithms - in wireless LANs and other in multi-hop wireless mesh networks. Through a detailed simulation, we show that in these two cases, the use of partially overlapping channels can improve the application throughput factor of the terminal to the terminal between 1.6 and 2.7, depending on the wireless node density. Finally, we observe that some of the overlapping concepts can be fl exibly designed to design effi cient channel access mechanisms in emerging software radio platforms. | Jing Fu Dongsheng Chen Jiafeng Gong | 2019 | Journal of Networking and Telecommunications2019，1，1： | 0 |
