3Effects of environmental factors on sulfamethoxazole photodegradation under simulated sunlight irradiation: Kinetics and mechanism显示文摘To advance the knowledge of the environmental fate of sulfamethoxazole(SMX),we systematically investigated the effects of natural water constituents and synthetic substances(i.e.,TiO2 nanoparticles(nTiO2) and Ti-doped β-Bi2O3(NTB)) on the photodegradation kinetics of SMX under xenon lamp irradiation.The photolysis of SMX in aqueous solution followed first-order kinetics.Our results showed that higher concentrations of SMX,fulvic acid,suspended sediments,NTB and higher pH value decreased the photodegradation rates of SMX,whereas H2O2 improved the SMX photodegradation.TiO2 nanoparticles had a dual effect on photodegradation due to their photocatalytic activity and photoabsorption of photons.No intermediates more toxic toward Vibrio fischeri than SMX were produced after direct photolysis and photocatalytic degradation for 3 hr.The photolysis of SMX involved three pathways:hydroxylation,cleavage of the sulfonamide bond,and fragmentation of the isoxazole ring.This study lays the groundwork for a better understanding of the environmental fate of SMX.Junfeng Niu Lilan Zhang Yang Li Jinbo Zhao Sidan Lv Keqing Xiao 2013Journal of Environmental Sciences2013,25,6:14

5PKM2 coordinates glycolysis with mitochondrial fusion and oxidative phosphorylation显示文摘A change in the metabolic flux of glucose from mitochondrial oxidative phosphorylation (OXPHOS) to aerobic glycolysis is regarded as one hallmark of cancer. However, the mechanisms underlying the metabolic switch between aerobic glycolysis and OXPHOS are unclear. Here we show that the M2 isoform of pyruvate kinase (PKM2), one of the rate-limiting enzymes in glycolysis, interacts with mitofusin 2 (MFN2), a key regulator of mitochondrial fusion, to promote mitochondrial fusion and OXPHOS, and attenuate glycolysis. mTOR increases the PKM2:MFN2 interaction by phosphorylating MFN2 and thereby modulates the effect of PKM2: MFN2 on glycolysis, mitochondrial fusion and OXPHOS. Thus, an mTOR-MFN2-PKM2 signaling axis couples glycolysis and OXPHOS to modulate cancer cell growth.Tong Li Jinbo Han Liangjie Jia Xiao Hu Liqun Chen Yiguo Wang 2019Protein & Cell2019,10,8:10
6Investigation of the characteristics and deactivation of catalytic active center of Cr-Al_2O_3 catalysts for isobutane dehydrogenation显示文摘Deactivation mechanism of Cr-Al2O3 catalyst and the interaction of Cr-Al in the dehydrogenation of isobutane, as well as the nature of the catalytic active center, were studied using XRD, SEM, XPS, H2-TPR, isobutane-TPR and TPO techniques. The results revealed that the deactivation of Cr-Al2O3 catalyst was mainly caused by carbon deposition on its surface. The Cr3+ion could not be reduced by hydrogen but could be reduced to Cr2+by hydrocarbons and monoxide carbon. The active center for isobutane dehydrogenation could be Cr2+/Cr3+produced from Cr6+by the on line reduction of hydrocarbon and carbon monoxide. The binding energy of Al3+was strongly affected by the state of chromium cations in the catalysts.Deren Fang Jinbo Zhao Wanjun Li Xu Fang Xin Yang Wanzhong Ren Huimin Zhang 2015Journal of Energy Chemistry2015,24,1:8
7A User-Centric Data Secure Creation Scheme in Cloud Computing显示文摘Due to the use of the cloud computing technology,the ownership is separated from the administration of the data in cloud and the shared data might be migrated between different clouds,which would bring new challenges to data secure creation,especially for the data privacy protection.We propose a User-centric data secure creation scheme(UCDSC) for the security requirements of resource owners in cloud.In this scheme,a data owner first divides the users into different domains.The data owner encrypts data and defines different secure managing policies for the data according to domains.To encrypt the data in UCDSC,we present an algorithm based on Access control conditions proxy re-encryption(ACC-PRE),which is proved to be master secret secure and Chosen-ciphertext attack(CCA) secure in random oracle model.We give the application protocols and make the comparisons between some existing approaches and UCDSC.SU Mang LI Fenghua SHI Guozhen GENG Kui XIONG Jinbo 2016Chinese Journal of Electronics2016,25,4:7
8Study on the hardening mechanism of cement asphalt binder显示文摘The hydration and hardening mechanism of cement asphalt binder(CAB) was studied.The early hydration process,hydration products and paste microstructure of CAB made by Portland cement and anionic asphalt emulsion were investigated by calorimetry,X-ray diffraction,and environmental scanning electron microscopy.The early hydration process of CAB can be characterized as 5 stages similar to those of Portland cement.There is no chemical reaction detected between cement and asphalt,hence no new hydration products other than those of Portland cement are produced.The hardening of CAB begins with the hydration of cement.When the hydration of cement comes into the acceleration period and its exothermic rate comes to the maximum,the coalescence of asphalt particles in asphalt emulsion is triggered.In the hardened system of CAB,it was found that the hydration products of cement form the skeleton and are covered by the continuous asphalt film.They formed an interpenetrating network system.The emulsifiers in the asphalt emulsion may retard the hydration process of cement.YANG JinBo,YAN PeiYu,KONG XiangMing & LI Xiang Key Laboratory of Structural Engineering and Vibration of Education Ministry of China,Department of Civil Engineering,Tsinghua University,Beijing 100084,China 2010Science China(Technological Sciences)2010,53,5:7
9The development of blood-retinal barrier during the interaction of astrocytes with vascular wall cells显示文摘Astrocytes are intimately involved in the formation and development of retinal vessels.Astrocyte dysfunction is a major cause of blood-retinal barrier injury and other retinal vascular diseases.In this study,the development of the retinal vascular system and the formation of the blood-retinal barrier in mice were investigated using immunofluorescence staining,gelatin-ink perfusion,and transmission electron microscopy.The results showed that the retinal vascular system of mice develops from the optic disc after birth,and radiates out gradually to cover the entire retina,taking the papilla optica as the center.First,the superficial vasculature is formed on the inner retinal layer; then,the vasculature extends into the inner and outer edges of the retinal inner nuclear layer,forming the deep vasculature that is parallel to the superficial vasculature.The blood-retinal barrier is mainly composed of endothelium,basal lamina and the end-feet of astrocytes,which become mature during mouse development.Initially,the naive endothelial cells were immature with few organelles and many microvilli.The basal lamina was uniform in thickness,and the glial end-feet surrounded the outer basal lamina incompletely.In the end,the blood-retinal barrier matures with smooth endothelia connected through tight junctions,relatively thin and even basal lamina,and relatively thin glial cell end-feet.These findings indicate that the development of the vasculature in the retina follows the rules of 'center to periphery' and 'superficial layer to deep layers'.Its development and maturation are spatially and temporally consistent with the functional performance of retinal neurons and photosensitivity.The blood-retinal barrier gradually becomes mature via the process of interactions between astrocytes and blood vessel cells.Huanling Yao Tianshi Wang Jiexin Deng Ding Liu Xiaofei Li Jinbo Deng 2014Neural Regeneration Research2014,9,10:6
10A genome-wide analysis of SWEET gene family in cotton and their expressions under different stresses显示文摘Background: The SWEET(Sugars will eventually be exported transporters) gene family plays multiple roles in plant physiological activities and development process. It participates in reproductive development and in the process of sugar transport and absorption, plant senescence and stress responses and plant-pathogen interaction. However,thecomprehensive analysis of SWEET genes has not been reported in cotton.Results: In this study, we identified 22, 31, 55 and 60 SWEET genes from the sequenced genomes of Gossypium arboreum, G. raimondii, G. hirsutum and G. barbadense, respectively. Phylogenetic tree analysis showed that the SWEET genes could be divided into four groups, which were further classified into 14 sub-clades. Further analysis of chromosomal location, synteny analysis and gene duplication suggested that the orthologs showed a good collinearity and segmental duplication events played a crucial role in the expansion of the family in cotton. Specific MtN3_slv domains were highly conserved between Arobidopsis and cotton by exon-intron organization and motif analysis. In addition, the expression pattern in different tissues indicated that the duplicated genes in cotton might have acquired new functions as a result of sub-functionalization or neo-funtionalization. The expression pattern of SWEET genes showed that the different genes were induced by diverse stresses. The identification and functional analysis of SWEET genes in cotton may provide more candidate genes for genetic modification.Conclusion: SWEET genes were classified into four clades in cotton. The expression patterns suggested that the duplicated genes might have experienced a functional divergence. This work provides insights into the evolution of SWEET genes and more candidates for specific genetic modification, which will be useful in future research.ZHAO Lanjie YAO Jinbo CHEN Wei LI Yan L Youjun GUO Yan WANG Junyi YUAN Li LIU Ziyang ZHANG Yongshan 2018Journal of Cotton Research2018,1,2:6
11LncRNA-MALAT1 mediates cisplatin resistance via miR-101-3p/VEGF-C pathway in bladder cancer显示文摘The mitotically associated lncRNA(MANCR)participates in breast cancer cell proliferation,while its involvement in other cancers is still unknown.In this study,we therefore studied the role of MANCR in mantle cell lymphoma(MCL).We found that serum MANCR and Runt-related transcription factor 2(RUNX2)were upregulated in MCL patients when compared with those in healthy controls.A positive correlation between serum MANCR and RUNX2 was found in MCL patients but not in controls.Upregulation of serum MANCR distinguished MCL patients from controls.MANCR overexpression promoted RUNX2 expression in MCL cells,while RUNX2 overexpression failed to significantly change the expression levels of MANCR.MANCR overexpression promoted the proliferation of MCL cells,while MANCR silencing inhibited the proliferation of MCL cells.In addition,RUNX2 overexpression attenuated the inhibitory effects of MANCR silencing on cell proliferation.However,MANCR overexpression and silencing had no significant effects on cell migration and invasion.Further bioinformatics analysis showed that MANCR may sponge miR-218 to upregulate RUNX2.Therefore,we conclude that downregulation of MANCR may inhibit cancer cell proliferation in MCL possibly by interacting with RUNX2.Peihua Liu Xiaozhou Li Yu Cui Jinbo Chen Chao Li Qiaqia Li Huihuang Li Xiangyang Zhang Xiongbing Zu 2019Acta Biochimica et Biophysica Sinica2019,51,11:6
12Photosynthesis, chilling acclimation and the response of antioxidant enzymes to chilling stress in mulberry seedlings显示文摘This study investigates the effects of cold-acclimation in conferring chilling tolerance in seedlings of the mulberry(Morus alba) variety ‘Qiuyu’. Changes in photosynthesis and antioxidant enzymes in chilling acclimatized(CA), and non-acclimatized(NA) seedlings were recorded during chilling stress(3 °C) and a recovery period(25 °C) each for 3 days. The results showed that CA plants had higher net photosynthetic rates(P_n), stomatal conductance(G_s), and maximum photochemical efficiency of photosystem Ⅱ(F_v/F_m) in response to chilling stress compared to NA. The seedlings maintained the same trends during the recovery stage. The responses of Q_A reduction degree (1-q_P) and prime electronic transfer rates(F_o) were lower in acclimatized than in non-acclimatized seedlings. Low-temperature acclimation and chilling stress also caused an increase in leaf proline and soluble sugar contents. Leaf malondialdehyde levels were significantly lower while ascorbate peroxidase(APX) activity was significantly higher in acclimatized seedlings, suggesting that elevated osmolytes and APX confer resistance to chilling temperatures. In this study on the response of mulberry seedlings to chilling stress, we also looked at the recovery process. The response to chilling determines whether mulberry leaves can survive under cold temperatures, while the recovery process determines whether photosynthesis can recover as soon as possible to avoid any secondary damage.Xiaojia Liu Nan Xu Yining Wu Jinbo li Haixiu Zhong Huihui Zhang 2019Journal of Forestry Research2019,30,6:5
13Fast-Suppressor Screening for New Components in Protein Trafficking,Organelle Biogenesis and Silencing Pathway in Arabidopsis thaliana Using DEX-Inducible FREE1-RNAi Plants显示文摘Membrane trafficking is essential for plant growth and responses to external signals.The plant unique FYVE domain-containing protein FREE1 is a component of the ESCRT complex(endosomal sorting complex required for transport).FREE1 plays multiple roles in regulating protein trafficking and organelle biogenesis including the formation of intraluminal vesicles of multivesicular body(MVB),vacuolar protein transport and vacuole biogenesis,and autophagic degradation.FREE1 knockout plants show defective MVB formation,abnormal vacuolar transport,fragmented vacuoles,accumulated autophagosomes,and seedling lethality.To further uncover the underlying mechanisms of FREE1 function in plants,we performed a forward genetic screen for mutants that suppressed the seedling lethal phenotype of FREE1-RNAi transgenic plants.The obtained mutants are termed as suppressors of free1(sof).To date,229 putative sof mutants have been identified.Barely detecting of FREE1 protein with M3plants further identified 84 FREE1-related suppressors.Also145 mutants showing no reduction of FREE1 protein were termed as RNAi-related mutants.Through next-generation sequencing(NGS)of bulked DNA from F2mapping population of two RNAi-related sof mutants,FREE1-RNAi T-DNA inserted on chromosome 1 was identified and the causal mutation of putative sof mutant is being identified similarly.These FREE1-and RNAi-related sof mutants will be useful tools and resources for illustrating the underlying mechanisms of FREE1 function in intracellular trafficking and organelle biogenesis,as well as for uncovering the new components involved in the regulation of silencing pathways in plants.Qiong Zhao Caiji Gao PoShing Lee Lin Liu Shaofang Li Tangjin Hu Jinbo Shen Shuying Pan Hao Ye Yunru Chen Wenhan Cao Yong Cui Peng Zeng Sheng Yu Yangbin Gao Liang Chen Beixin Mo Xin Liu Shi Xiao Yunde Zhao Silin Zhong Xuemei Chen Liwen Jiang 2015Journal of Genetics and Genomics2015,42,6:4
14Assisting Bi_(2)MoO_(6) microspheres with phenolic resin-based ACSs as attractive tailor-made supporter for highly-efficient photocatalytic CO_(2) reduction显示文摘It is rather essential to design glorious system with high CO_(2) adsorption capacity and electron migration efficiency for improving selective and effective CO_(2) reduction into solar fuels.Here,as-synthesized phenolic resin spheres via suspension polymerization were carbonized and activated by water vapor to obtain activated carbon spheres(ACSs).Subsequently,Bi_(2)MoO_(6)/ACSs were prepared via hydrothermal-impregnated method.The systematical characterizations of samples,including XRD,XPS,SEM,EDX,DRS,BET,PL,CO_(2) adsorption isotherm,EIS and transient photocurrent,were analyzed.The results clearly demonstrated that Bi_(2)MoO_(6) with suitable oxidation reduction potentials and bandgap and ACSs with admirable CO_(2) adsorption and electrical conductivity not only enhanced separation efficiency of photoindued electron-hole pair,but also displayed as 1.8 times CO_(2) reduction activity to CO as single Bi_(2)MoO_(6) sample under Xe-lamp irradiation.Finally,a concerned photocatalytic CO_(2) reduction mechanism was proposed and investigated.Our findings should provide innovative guidance for designing a series of photocatalytic CO_(2) reduction materials with highly efficient and selective ability.Xiaochao Zhang Guangmin Ren Changming Zhang Jinbo Xue Qiang Zhao Rui Li Yunfang Wang Caimei Fan 2021Green Energy & Environment2021,6,5:4

17Rapid growth of a large-scale(600 mm aperture) KDP crystal and its optical quality显示文摘Potassium dihydrogen phosphate(KDP) single crystals are the only nonlinear crystals currently used for electro-optic switches and frequency converters in inertial confinement fusion research, due to their large dimension and exclusive physical properties. Based on the traditional solution-growth process, large bulk KDP crystals, usually with sizes up to600 × 600 mm2 so as to make a frequency doubler for the facility requirement loading highly flux of power laser, can be grown in standard Holden-type crystallizers, without spontaneous nucleation and visible defects, one to two orders of magnitude faster than by conventional methods. Pure water and KDP raw material with a few ion impurities such as Fe,Cr, and Al(less than 0.1 ppm) were used. The rapid-growth method includes extreme conditions such as temperature range from 60 to 35℃ , overcooling up to 5℃ , growth rates exceeding 10 mm/day, and crystal size up to 600 mm. The optical parameters of KDP crystals were determined. The optical properties of crystals determined indicate that they are of favorable quality for application in the facility.Guohui Li Guozong Zheng Yingkun Qi Peixiu Yin En Tang Fei Li Jing Xu Taiming Lei Xiuqin Lin Min Zhang Junye Lu Jinbo Ma Youping He Yuangen Yao 2014High Power Laser Science and Engineering2014,2,1:3

19Removal of Nitride from Shale Diesel Fraction with FeCl3-Based Ionic Liquids显示文摘FeCl3-based ionic liquid [Bmim]Br/FeCl3 with lower viscosity was synthesized and its structure was character-ized with FT-IR spectroscopy. The denitrogenation performance of the ionic liquid was investigated using the Fushun shale diesel fraction with high nitrogen content. Experimental results showed that the ionic liquid presented good denitrogenation performance and the basic N and total N removal efficiency can reach 95.29% and 89.77% under conditions covering a tem-perature of 30 ℃, an IL/oil mass ratio of 1:1, an extraction time of 30 min, and a settling time of 2 h. Correspondingly, the basic N and total N contents in shale diesel fraction dropped from the original 5454 μg/g and 9832 μg/g to 257 μg/g and 1006 μg/g, respectively. In addition, the basic-N removal efficiency can still reach 60% at an IL/oil mass ratio of 1:7 during four recycles of the ionic liquid.Liu Jie Liu Jinbo Li Wenshen 2019China Petroleum Processing & Petrochemical Technology2019,21,3:3
20Identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge, Guyana显示文摘Here,we report the identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge,Guyana.In March 2019,14 employees of Chongqing Bosai Mining Company,China,working in a manganese mining of Guyana,had unexplained fever,and two of them died.We obtained lung and brain tissues as well as the blood samples from the two deceased cases(patient No.1 and 2),and bronchoscopy lavages and cerebrospinal fluid samples from one severe case(patient No.3),respectively.All samples were tested by pathological examination,high-throughput sequencing,and real-time PCR.Pathological detection showed the presence of spore-like structures in the lung tissue of patient No.1,indicating a fungal infection in this patient.Nanopore sequencing identified the existing of H.capsulatum in the lung tissue sample within 13 h.Next-generation sequencing identified specific fragments of H.capsulatum in all of the samples tested(lung,brain and blood serum from the deceased cases,and plasma from the severe case).Real-time PCR assays did not reveal any viral infection related to transmission from bat feces.We conclude that H.capsulatum was the causative pathogen of this disease cluster based on epidemiologic,clinical,pathological and nucleic acid evidence.Ji Wang Weimin Zhou Hua Ling Xiaoping Dong Yi Zhang Jiandong Li Yong Zhang Jingdong Song William J.Liu Yang Li Ruiqing Zhang Wei Zhen Kun Cai Shuangli Zhu Dongyan Wang Jinbo Xiao Yigang Tong Wenli Liu Lihua Song Wei Wu Yang Liu Xiang Zhao Ruihuan Wang Sheng Ye Jing Wang Roujian Lu Baoying Huang Fei Ye Wenwen Lei Rongbao Gao Qi Shi Cao Chen Jun Han Wenbo Xu George F.Gao Xuejun Ma Guizhen Wu 2019Biosafety and Health2019,1,3:3
