1Thermoplastic Starch Prepared with Different Plasticizers: Relation between Degree of Plasticization and Properties显示文摘Ethylene glycol, glycerol, sorbitol, formamide, and urea were used as plasticizers for the preparation of thermoplastic starch(TPS) from corn starch. The properties of TPS were tested by analysis method. The results showed that TPSs were more highly plasticized with amines than alcohols. For the same type of plasticizer, the degree of plasticization decreased as the molecular weight of plasticizer increased. The relationship between plasticization degree and TPS properties was characterized and described by mechanical properties and water absorption. The experimental results showed that when the degree of plasticization increased, the tensile strength decreased and the elongation at breakage and water absorption increased.左迎峰 GU Jiyou TAN Haiyan 张彦华 2015Journal of Wuhan University of Technology(Materials Science)2015,30,2:8
2LKB1 orchestrates dendritic cell metabolic quiescence and anti-tumor immunity显示文摘Den dritic cells(DCs)play a pivotal role in priming adaptive immunity.However,the in volveme nt of DCs in con trolling excessive and deleterious T cell responses remains poorly defined.Moreover,the metabolic dependenee and regulation of DC function are unclear.Here we show that LKB1 signaling in DCs functions as a brake to restrain excessive tumor-promoting regulatory T cell(Treg)and Th17 cell responses,thereby promoting protective anti-tumor immunity and maintaining proper immune homeostasis.LKB1 deficiency results in dysregulated metabolism and mTOR activation of DCs.Loss of LKB1 also leads to aberrant DC maturation and production of cytokines and immunoregulatory molecules.Blocking mTOR signaling in LKB1-deficient DCs partially rectifies the abno rmal phe no types of DC activation and Treg expansio n,whereas unc on trolled Th17 resp on ses depend upon IL-6-STAT3 signaling.By coordi nating metabolic and immune quiesce nee of DCs,LKB1 acts as a crucial signali ng hub in DCs to enforce protective anti-tumor immunity and normal immune homeostasis.Yanyan Wang Xingrong Du Jun Wei Lingyun Long Haiyan Tan Cliff Guy Yogesh Dhungana Chenxi Qian Geoffrey Neale Yang-Xin Fu Jiyang Yu Junmin Peng Hongbo Chi 2019Cell Research2019,29,5:3
3Tuning the strength of built-in electric field in 2D/2D g-C_(3)N_(4)/MS_(2) and g-C_(3)N_(4)/ZrS_(2) S-scheme heterojunctions by nonmetal doping显示文摘Single photocatalysts usually exhibit unsatisfactory performance due to the serious recombination of photogenerated electron‒hole pairs.Combining two photocatalysts to construct S-scheme heterojunction could solve this problem.In S-scheme mechanism,the interfacial built-in electric field(IEF)provides a vital driving force for efficient charge separation.Modifying the IEF is a feasible strategy to further improve the photocatalytic activity.Herein,a novel idea of tuning the strength of IEF in 2D/2D graphitic carbon nitride(g-C_(3)N_(4))/MS2(M=Sn,Zr)S-scheme heterojunctions by nonmetal doping was developed by employing density functional theory calculation.Three nonmetal elements(O,P,and S)were severally introduced into g-C_(3)N_(4)/MS_(2) composites.Charge density difference suggested that O and S doping led to increased interfacial electron transfer,while P doping had minimal influence.As expected,the calculated field strength of O-and S-doped g-C_(3)N_(4)/MS_(2) composites was significantly larger than that of pristine and P-doped g-C_(3)N_(4)/MS_(2) composites.Therefore,O and S doping endowed g-C_(3)N_(4)/MS_(2) Sscheme heterojunctions with enhanced IEF and more thorough charge transfer.Correspondingly,the experimentally synthesized O-C_(3)N_(4)/ZrS_(2) composite exhibited better photocatalytic H2-production activity than g-C_(3)N_(4)/ZrS_(2) composite.This work proposed an original idea of employing proper nonmetal doping to magnify the advantage of S-scheme heterojunction in accelerating charge separation.Bicheng Zhu Haiyan Tan Jiajie Fan Bei Cheng Jiaguo Yu Wingkei Ho 2021Journal of Materiomics2021,7,5:3
4Effect of Starch/Polylactic Acid Ratio on the Interdependence of Two-Phase and the Properties of Composites显示文摘Starch/polylactic acid(PLA) composites were prepared by melt extrusion, with corn starch and PLA as raw materials, glycerol as the plasticizer. Effects of starch/PLA ratio on the interdependence of two-phase and other properties of the composites were studied. The combination of results of TGA with SEM indicated that the interdependence between starch and PLA was increased gradually as the starch/PLA ratio reduced. DSC results showed that the glass transition temperature(Tg), melting temperature(Tm) and degree of crystallinity of PLA in composites were increased gradually, whereas the cold crystallization temperature(Tc) was gradually decreased as the starch/PLA ratio reduced. The rheological properties of composites were closely related with the interdependence of two-phase, with reducing starch/PLA proportion, the interdependence was increased, and then the strain for storage modulus was firstl reduced and then gradually increased. Frequency scanning showed that the storage modulus and complex viscosity were decreased with reducing starch content. As the starch/PLA ratio reduced, the matrix phase PLA was increased, so that the strength of composites was increased gradually, whereas water absorption rate was decreased gradually.左迎峰 GU Jiyou CAO Jun WEI Shuangying TAN Haiyan 张彦华 2015Journal of Wuhan University of Technology(Materials Science)2015,30,5:3
5Drug resistance mutation profiles of the drug-nave and first-line regimen-treated HIV-1-infected population of Suzhou, China显示文摘Little is known about the prevalence of drug-resistant mutations in HIV-1-positive individuals in Suzhou, China. To elucidate the transmitted drug resistance(TDR) and acquired drug resistance mutation(ADR) profiles, we collected blood specimens from 127 drug-naive and 117 first-line drugtreated HIV-1-infected individuals sampled from 2014 to 2016 in Suzhou. We successfully amplified po/fragments from 100 drug-naive and 20 drug-treated samples. We then determined the drugresistant mutations to protease(PR) and reverse-transcriptase(RT) inhibitors according to the Stanford drug resistance database. Overall, 11 and 13 individuals had transmitted(drug-naive group) and acquired(treated group) resistance mutations, respectively. Six transmitted drugresistant mutations were found, including two mutations(L33F and L76V) in the protease region and four(K70N/E and V179D/E) in the RT region. Only L76 V was a major mutation, and K70N/E and V179D/E are known to cause low-level resistance to RT inhibitors. All 13 treated participants who had major drug resistance mutations demonstrated intermediate to high resistance to efavirenz and nevirapine, and six had a treatment duration of less than three months. No major mutations to RT inhibitors were found, implying that the epidemic of transmitted resistance mutations was not significant in this area. Our results suggest that more frequent virus load and drug resistance mutation tests should be conducted for individuals receiving antiretroviral treatment, especially for newly treated patients. Our research provides insights into the occurrence of HIV-1 drug resistance in Suzhou and will help to optimize the treatment strategy for this population.Tingting Li Feng Qian Ting Yuan Weilu Xu Li Zhu Jinlong Huang Haiyan Wang Yueping Zhu Yinling Wang Xiaohong Li Saihong Gu Zhuqing Tan Hui Chen Xiangrong Luo Wei Zhu Weniuan Lu Ping Xu Ming Li Yuying Chen Yong Gao Rongge Yang Chuanwu Zhu Binlian Sun 2017Virologica Sinica2017,32,4:2
6Photodynamic therapy based on organic small molecular fluorescent dyes显示文摘Photodynamic therapy(PDT) has shown promise as an effective treatment modality for cancer and other localized diseases due to its noninvasive properties and spatiotemporal selectivity. Near-infrared(NIR)fluorescent dyes based on organic small molecules are characterized with low cytotoxicity, good biocompatibility and excellent phototoxicity, which are widely used in PDT. In this review, we attempt to summarize the development of imaging-induced PDT based on organic small molecules and classify it according to the structures of dyes including cyanines, 4,4-difluoro-4-bora-3 a,4 a-diaza-s-indacene(BODIPY) analogues, phthalocyanine and other agents such as rhodamine analogues.Li Li Yisha Chen Weijie Chen Ying Tan Haiyan Chen Jun Yin 2019Chinese Chemical Letters2019,30,10:2
7Cocoon Silk-Derived, Hierarchically Porous Carbon as Anode for Highly Robust Potassium-Ion Hybrid Capacitors显示文摘Potassium-ion hybrid capacitors(KIHCs) have attracted increasing research interest because of the virtues of potassium-ion batteries and supercapacitors.The development of KIHCs is subject to the investigation of applicable K+storage materials which are able to accommodate the relatively large size and high activity of potassium.Here,we report a cocoon silk chemistry strategy to synthesize a hierarchically porous nitrogen-doped carbon(SHPNC).The as-prepared SHPNC with high surface area and rich N-doping not only offers highly efficient channels for the fast transport of electrons and K ions during cycling,but also provides sufficient void space to relieve volume expansion of electrode and improves its stability.Therefore,KIHCs with SHPNC anode and activated carbon cathode afford high energy of 135 Wh kg-1(calculated based on the total mass of anode and cathode),long lifespan,and ultrafast charge/slow discharge performance.This study defines that the KIHCs show great application prospect in the field of high-performance energy storage devices.Haiyan Luo Maoxin Chen Jinhui Cao Meng Zhang Shan Tan Lei Wang Jiang Zhong Hongli Deng Jian Zhu Bingan Lu 2020Nano-Micro Letters2020,12,9:2
8Geological and geochemical characteristics of the Baogudi Carlintype gold district(Southwest Guizhou, China) and their geological implications显示文摘The newly discovered Baogudi gold district is located in the southwestern Guizhou Province,China,where there are numerous Carlin-type gold deposits.To better understand the geological and geochemical characteristics of the Baogudi gold district,we carried out petrographic observations,elemental analyses,and fluid inclusion and isotopic composition studies.We also compared the results with those of typical Carlin-type gold deposits in southwestern Guizhou.Three mineralization stages,namely,the sedimentation diagenesis,hydrothermal(main-ore and late-ore substages),and supergene stages,were identified based on field and petrographic observations.The main-ore and late-ore stages correspond to Au and Sb mineralization,respectively,which are similar to typical Carlin-type mineralization.The mass transfer associated with alteration and mineralization shows that a significant amount of Au,As,Sb,Hg,Tl,Mo,and S were added to mineralized rocks during the main-ore stage.Remarkably,arsenic,Sb,and S were added to the mineralized rocks during the late-ore stage.Element migration indicates that the sulfidation process was responsible for ore formation.Four types of fluid inclusions were identified in ore-related quartz and fluorite.The main-ore stage fluids are characterized by an H2O–NaCl–CO2–CH4±N2system,with medium to low temperatures(180–260℃)and low salinity(0–9.08%NaCl equivalent).The late-ore stage fluids featured H2O–NaCl±CO2±CH4,with low temperature(120–200℃)and low salinity(0–7.48%Na Cl equivalent).The temperature,salinity,and CO2and CH4concentrations of ore-forming fluids decreased from the main-ore stage to the late-ore stage.The calculated δ^13C,d D,and δ^18O values of the ore-forming fluids range from-14.3 to-7.0%,-76 to-55.7%,and 4.5–15.0%,respectively.Late-ore-stage stibnite had δ^34S values ranging from-0.6 to 1.9%.These stable isotopic compositions indicate that the ore-forming fluids originated mainly from deep magmatic hydrothermal fluids,with minor contributions from strata.Collectively,the Baogudi metallogenic district has geological and geochemical characteristics that are typical of Carlin-type gold deposits in southwest Guizhou.It is likely that the Baogudi gold district,together with other Carlin-type gold deposits in southwestern Guizhou,was formed in response to a single widespread metallogenic event.Songtao Li Yong Xia Jianzhong Liu Zhuojun Xie Qinping Tan Yimeng Zhao Minghua Meng Lijin Tan Rong Nie Zepeng Wang Guanghong Zhou Haiyan Guo 2019Acta Geochimica2019,38,4:1

13Effects of Ovarian Preservation Time on in vitro Maturation and in vitro Fertilization of Oocytes from Slaughtered Sheep显示文摘[Objectives] The aim was to study the effects of ovarian preservation time on in vitro fertilization of oocytes from slaughtered sheep. [Methods] The collected ovaries were randomly and evenly divided into four groups. They were preserved in physiological saline containing penicillin( 100 IU/ml) and streptomycin( 100 μg/ml) at 15-20 ℃ for 0( Control),6,12 and 18 h,respectively. Then,the oocytes were subjected to in vitro fertilization. [Results]The maturation rates,cleavage rates and blastocyst rates of the oocytes preserved for 6 and 12 h showed no significant differences compared with those of the oocytes preserved for0 h( 72. 03%,70. 87% vs. 73. 68%; 74. 12%,72. 60% vs. 74. 49%; 22. 22%,20. 75% vs. 23. 29%)( P > 0. 05). There were also no significant differences in maturation rate,cleavage rate or blastocyst rate between the oocytes preserved for 18 and 0 h( P > 0. 05). [Conclusions] Within a certain rage( 0-18 h),storage time of ovary at 15-20 ℃ does not affect the continued development of oocytes from slaughtered sheep.Hongyan LANG Xiaohui LIU Pengju ZHANG Weixia WANG Haiyan LIU Chengcheng TAN Xintao LI 2018Agricultural Biotechnology2018,7,3:1

15GPR Surveying in the kernel area of Grove Mountains,Antarctica显示文摘The Grove Mountains, located between the Zhongshan Station and Dome A, are a very important area in inland Antarctic research. China has organized five investigations of the Grove Mountains, encompassing the geological structure, ancient climate, meteorites, ice-movement monitoring, basic mapping, meteorological observations, and other multi-disciplinary observational studies. During the 26th Chinese National Antarctic Research Expedition in 2010, the Grove Mountains investigation team applied specialized ground-penetrating radar(GPR) to survey subglacial topography in the eastern kernel area of the Grove Mountains. In this paper, we processed GPS and GPR data gathered in the field and drew, for the first time, two subglacial topographic maps of the Grove Mountains kernel area using professional graphics software. The preliminary results reveal the mystery of the nunatak landform of this area, give an exploratory sense of the real bedrock landforms, and indicate a possible sedimentary basin under the Pliocene epoch fossil ice in the Grove Mountains area. Additionally, it has been proven from cross-sectional analysis between Mount Harding and the Zakharoff ridge that the box-valley shape between two nunataks has already matured. ′WANG Zemin TAN Zhi AI Songtao LIU Haiyan CHE Guowei 2014Advances in Polar Science2014,25,1:1
16Physiological responses and adjustment mechanisms of the dominate species of natural vegetation of Eastern Tengger Desert显示文摘Reaumuria soongorica and Salsola passerina have significant differences in ecophysiological characteristics, which change with the environmental variations. Although they live together for a long period of time, their adaptive mechanisms to environmental stresses are very different. As two extreme xerophytes, Reaumuria soongorica and Salsola passerina differ significantly from other psammophytes in ecophysiological characteristics; they can survive in lower water potential, and can even grow in piedmont areas. Low water potential may be related to the existence of osmosis-regulating substance, such as praline, which can strengthen the capacity of water absorption. Compared to other psammophytes, Reaumuria soongorica and Salsola passerina have a higher degree of photo-inhibition under the same condition, and the photo-inhibition can lead to destruction of the photosynthetic pigment, nevertheless, this photo-inhibition can be repaired under suitable conditions in the morning and evening.HaiYan Zhou HuiJuan Tan ZhiShan Zhang XiaoHong Jia HengWen Fan JianLi Yuan 2010Research in Cold and Arid Regions2010,2,5:1

18Biomass increment and mortality losses in tropical secondary forests of Hainan, China显示文摘Secondary forests, created after heavy logging,are an important part of China's forests. We investigated forest biomass and its accumulation rate in 38 plots in a tropical secondary forest on Hainan Island. These secondary forests are moderate carbon sinks, averaging1.96–2.17 t C ha-1 a-1. Biomass increment is largely by medium-sized(10–35 m) trees. Tree mortality accounts for almost 30% of the biomass and plays a negligible role in biomass accumulation estimates. Mortality rate is highly dependent on tree size. For small trees and seedlings, it is related to competition due to elevated irradiance after logging. Regarding prospective biomass and rates of accumulation, recovery is not as rapid as in secondary forests of cleared land. Therefore, tropical forests are susceptible to logging operations and need careful forest management.Junfu Zhao Chunsheng He Chunlin Qi Xu Wang Haiyan Deng Chunxin Wang Haiwei Liu Lianyan Yang Zhenghong Tan 2019Journal of Forestry Research2019,30,2:1
19Broadly neutralizing antibodies derived from the earliest COVID-19 convalescents protect mice from SARS-CoV-2 variants challenge显示文摘Coronavirus disease 2019(COviD-19)was first reported three years ago,when a group of individuals were infected with the original SARS-CoV-2 strain,based on which vaccines were developed.Here,we develop six human monoclonal antibodies(mAbs)from two elite convalescents in Wuhan and show that these mAbs recognize diverse epitopes on the receptor binding domain(RBD)and can inhibit the infection of SARS-CoV-2 original strain and variants of concern(VOCs)to varying degrees,including Omicron strains XBB and XBB.Qianyun Liu Haiyan Zhao Zhiqiang Li Zhen Zhang Rui Huang Mengxue Gu Ke Zhuang Qing Xiong Xianying Chen Weiyi Yu Shengnan Qian Yuzhen Zhang Xue Tan Muyi Zhang Feiyang Yu Ming Guo Zhixiang Huang Xin Wang Wenjie Xiang Bihao Wu Fanghua Mei Kun Cai Limin Zhou Li Zhou Ying Wu Huan Yan heng Cao Ke Lan Yu Chen 2023Signal Transduction and Targeted Therapy2023,8,10:0
20CdS decorated resorcinol-formaldehyde spheres as an inorganic/organic S-scheme photocatalyst for enhanced H_(2)O_(2)production显示文摘Photocatalytic H_(2)O_(2)production provides a clean and sustainable strategy for artificial photosynthesis.Herein,an inorganic/organic composite photocatalyst was fabricated by in-situ growth of CdS nanoparticles on the surface of resorcinol-formaldehyde(RF)resin spheres.RF spheres played multiple roles:(i)acting as a substrate for the growth of CdS and constructing a core-shell structure with seamless con-tact;(ⅱ)improving visible light absorption of CdS;(ⅲ)forming an S-scheme heterojunction with CdS and promoting the charge separation and transfer.Consequently,under visible light illumination,CdS/RF composite presented remarkably enhanced H_(2)O_(2)production activity.Its H_(2)O_(2)yield in 60 min was 801μmol L^(-1),which was 5.2 and 1.5 times higher than that of RF spheres and CdS hollow spheres,respectively.The charge migration between CdS and RF followed the S-scheme photocatalytic mechanism,which was verified by work function measurement,ex-situ and in-situ irradiated X-ray photoelectron spectroscopy.This work brings a novel insight into designing RF-based inorganic/organic S-scheme heterojunction pho-tocatalysts for efficient H_(2)O_(2)production.Bicheng Zhu Jingjing Liu Jian Sun Fei Xie Haiyan Tan Bei Cheng Jianjun Zhang 2023Journal of Materials Science & Technology2023,,31:0
