| 1 | Polymorphisms of three gene-derived STS on pig chromosome 13q41 are associated with susceptibility to enterotoxigenic Escherichia coli F4ab/ac in pigs显示文摘Neonatal diarrhea caused by enterotoxigenic Escherichia coli(ETEC)F4 is a common and serious disease,resulting in significant economical loss in the pig industry.The locus encoding ETEC F4 receptor has been mapped to pig chromosome(SSC)13q41,and one of the most significantly linked markers is S0075.In this study,we selected three genes including SLC12A8,MYLK and KPNA1 from a chromosomal region flanking S0075 on SSC13 to develop pig specific sequence tagged sites(STS). Seven single nucleotide polymorphisms were identified in the three pig STS using DNA of four full-sib susceptible and resistant animals in a White Duroc×Erhualian intercross.All grandparents,parents and 755 offspring in the intercross were genotyped for three polymorphisms,including SLC12A8 g.159A>G,MYLK g.1673A>G and KPNA1 g.306A>G.Family-based transmission disequilibrium test(TDT) revealed that all polymorphisms and the corresponding haplotypes are significantly associated with ETEC F4ab/ac(especially F4ac)brush border adhesion phenotypes,indicating that these polymor- phism are in linkage disequlibrium with causal mutation(s)of the gene encoding ETEC F4ab/ac receptor. Our results strengthen the evidence for the involvement of SSC13q41 in high acquiring risk of ETEC F4ab/ac infection,and provide novel polymorphic markers for fine mapping of the ETEC F4ab/ac receptor locus. | HUANG Xiang 1 ,REN Jun 1 ,YAN XueMing 1,2 ,PENG QiuLing 1 ,TANG Huan 1 ,ZHANG Bo 1 ,JI HuaYuan 1 , YANG ShuJin1&HUANG LuSheng 1 1Key Laboratory for Animal Biotechnology of Jiangxi Province and the Ministry of Agriculture of China,Jiangxi Agricultural University, Nanchang 330045,China 2Department of Biology,Nanchang University of Science and Technology,Nanchang 330038,China | 2008 | Science China(Life Sciences)2008，51，7： | 8 |

| 3 | CHANGES IN MONSOON AND TROPICAL CYCLONE EXTREME PRECIPITATION IN SOUTHEAST CHINA FROM 1960 TO 2012显示文摘Using daily precipitation data from 110 stations in Southeast China from 1960 to 2012,the extreme precipitation(EP)events associated with monsoon and tropical cyclones were examined using the Objective Synoptic Analysis Technique.In Southeast China,the extreme precipitation associated with tropical cyclones(TEP),which mainly occur in the summer(July–September),accounted for 27.9%of the total extreme precipitation amount,with 40–50%in the coastal regions.While the regional mean TEP amount showed an inconspicuous trend,total EP and monsoon EP(MEP)both showed an increasing trend,with the MEP trend being statistically significant.Although there was little change in the frequency of tropical cyclones affecting Southeast China,the TEP contribution to frequency increased with increasing EP threshold and the frequency of TEP with daily precipitation of more than 300 mm showed an increasing trend in the background of global climate change.The upward trend in the highest-threshold TEP events presents a challenge for mitigation of the damage associated with tropical cyclones. | ZHIZ HONG SU FUMIN REN JIN WEI XIAOHONG LIN SHUNJI SHI XUEMING ZHOU | 2015 | Tropical Cyclone Research and Review2015，4，1： | 3 |
| 4 | Self-assembled FeS-based cascade bioreactor with enhanced tumor penetration and synergistic treatments to trigger robust cancer immunotherapy显示文摘Major challenges for cancer treatment are how to effectively eliminate primary tumor and sufficiently induce immunogenic cell death(ICD)to provoke a robust immune response for metastasis control.Here,a self-assembled cascade bioreactor was developed to improve cancer treatment with enhanced tumor penetration and synergistic therapy of starvation,chemodynamic(CDT)and photothermal therapy.Ultrasmall Fe S-GOx nanodots were synthesized with glucose oxidase(GOx)as template and induced by paclitaxel(PTX)to form self-assembling Fe S-GOx@PTX(FGP)via hydrophobic interaction.After accumulated at tumor sites,FGP disassembles to smaller Fe S-GOx for enhanced deep tumor penetration.GOx maintains high enzymatic activity to catalyze glucose with assistant of oxygen to generate hydrogen peroxide(H2O2)as starvation therapy.Fenton reaction involving the regenerated H_(2)O_(2) in turn produced more hydroxyl radicals for enhanced CDT.Following near-infrared laser at 808 nm,FGPs displayed pronounced tumor inhibition in vitro and in vivo by the combination therapy.The consequent increased exposure to calreticulin amplified ICD and promoted dendritic cells maturation.In combination with anti-CTLA4 checkpoint blockade,FGP can absolutely eliminate primary tumor and avidly inhibit distant tumors due to the enhanced intratumoral infiltration of cytotoxic T lymphocytes.Our work presents a promising strategy for primary tumor and metastasis inhibition. | Hao Ren Jiahui Yong Qingqing Yang Zhen Yang Zhangya Liu Yan Xu Hao Wang Xing Jiang Wenjun Miao Xueming Li | 2021 | Acta Pharmaceutica Sinica B2021，11，10： | 2 |

| 16 | Congruences on ideal nil-extension of completely regular semigroups显示文摘Let S be an ideal nil-extension of a completely regular semigroup K by a nil semigroup Q with zero. A concept of admissible congruence pairs (δ,ω) of S is introduced, where δ and ω are a congruence on Q and a congruence on K respectively. It is proved that every congruence on S can be uniquely respresented by an admissible congruence pair (δ,ω) of S. Suppose that ρ K denotes the Rees congruence induced by the ideal K of S. Then it is shown that for any congruence σ on S,a mapping Γ:σ|→(σ Q,σ K) is an order-preserving bijection from the set of all congruences on S onto the set of all admissible congruence pairs of S,where σ K is the restriction of σ to K and σ Q=(σ∨ρ K)/ρ K. Moreover,the lattice of congruences of S is also discussed. As a special case,every congruence on completely Archimedean semigroups S is described by an admissible quarterple of S. The following question is asked: Is the lattice of congruences of the completely Archimedean semigroup a semimodular lattice? | REN Xueming 1, 2 GUO Yuqi 2 and CEN Jiaping (Shum Kar-ping) 31.

| 17 | Recent improvements to the physical model of the Bohai Sea,the Yellow Sea and the East China Sea Operational Oceanography Forecasting System显示文摘In order to satisfy the increasing demand for the marine forecasting capacity,the Bohai Sea,the Yellow Sea and the East China Sea Operational Oceanography Forecasting System(BYEOFS)has been upgraded and improved to Version 2.0.Based on the Regional Ocean Modeling System(ROMS),a series of comparative experiments were conducted during the improvement process,including correcting topography,changing sea surface atmospheric forcing mode,adjusting open boundary conditions,and considering atmospheric pressure correction.(1)After the topography correction,the volume transport and meridional velocity maximum of Yellow Sea Warm Current increase obviously and the unreasonable bending of its axis around 36.1°N,123.5°E disappears.(2)After the change of sea surface forcing mode,an effective negative feedback mechanism is formed between predicted sea surface temperature(SST)by the ocean model and sea surface radiation fluxes fields.The simulation errors of SST decreased significantly,and the annual average of root-mean-square error(RMSE)decreased by about 18%.(3)The change of the eastern lateral boundary condition of baroclinic velocity from mixed Radiation-Nudging to Clamped makes the unreasonable westward current in Tsushima Strait disappear.(4)The adding of mean sea level pressure correction option which forms the mean sea level gradient from the Bohai Sea and the Yellow Sea to the western Pacific in winter and autumn is helpful to increasing the fluctuation of SLA and outflow of the Yellow Sea when the cold high air pressure system controls the Yellow Sea area. | Ang Li Xueming Zhu Yunfei Zhang Shihe Ren Miaoyin Zhang Ziqing Zu Hui Wang | 2021 | Acta Oceanologica Sinica2021，40，11： | 1 |
| 18 | Identification and expression profiles of gustatory receptor genes in Bactrocera minax larvae(Diptera:Tephritidae):Role of BminGR59f in larval growth显示文摘Insects employ various types of gustatory receptors(GRs)to identify nutrient-rich food and avoid toxic substances.The larval gustatory system is the critical checkpoint for food acceptance or rejection.As a specialist herbivore,the larvae of Bactrocera minax feed only on unripe citrus fruits.However,how larvae use GRs to check and adapt to the secondary metabolites in unripe citrus fruits remains unknown.In this study,we first performed developmental expression profiles showing that most BminGRs genes were highly expressed in 1st and 2nd instar larvae and that tissue-specific expression indicated high expression of most BminGRs genes in the mouthparts of 2nd instar larvae.Furthermore,we found that silencing BminGR59f by RNA interference(RNAi)affected the growth of 2nd instar B.minax larvae.Hesperidin and naringin were screened as ligands of BminGR59f via RNAi and cell calcium imaging,and the combination of these two flavones increased the body weight of larvae.In summary,we identified a novel gustatory perception pattern in B.minax for detecting hesperidin and naringin,which boosted the growth of B.minax larvae.These results shed light on how specialist herbivores detect and adapt to host metbolites in adverse environments depending on larval GRs. | Guijian Zhang Shuai Cao Tong Guo Haoran Wang Xuewei Qi Xueming Ren Changying Niu | 2022 | Insect Science2022，29，5： | 0 |
| 19 | Evaluation of boron isotopes in halite as an indicator of the salinity of Qarhan paleolake water in the eastern Qaidam Basin, western China显示文摘In this study, nineteen brine samples from the Qarhan Salt Lake(QSL) in western China were collected and analyzed for boron(B) and chlorine(Cl) concentrations, total dissolved solids(TDS), pH values and stable B isotopic compositions. The B concentrations and δ^(11) B values of brines in the QSL range from 51.6 mg/L to138.4 mg/L, and from +9.32& to +13.08&, respectively. By comparison of B concentrations and TDS of brines in QSL with evaporation paths of brackish water, we found that B enrichment of brines primarily results from strong evaporation and concentration of Qarhan lake water. Combining with comparisons of B concentrations, TDS, p H values and δ^(11) B values of brines, previously elemental ratios(K/Cl, Mg/Cl, Ca/Cl, B/Cl) and δ^(11) B values of halite from a sediment core(ISL1 A), we observe good correlations between B concentrations and TDS, TDS and pH values, pH and δ^(11) B values of brines, which demonstrate that higher B concentrations and more positive δ^(11) B values of halite indicate higher salinity of the Qarhan paleolake water as well as drier paleoclimatic conditions. Based on this interpretation of the δ^(11) B values of halite in core ISL1 A, higher salinity of the Qarhan paleolake occurred during two intervals, around 46-34 ka and26-9 ka, which are almost coincident with the upper and lower halite-dominated salt layers in core ISL1 A,drier climate phases documented from the δ^(18) O record of carbonate in core ISL1 A and the paleomoisture record in monsoonal central Asia, and a higher solar insolation at 30°N. These results demonstrate that the δ^(11) B values of halite in the arid Qaidam Basin could be regarded as a new proxy for reconstructing the salinity record of paleolake water as well as paleoclimate conditions. | Yongsheng Du Qishun Fan Donglin Gao Haicheng Wei Fashou Shan Binkai Li Xiangru Zhang Qin Yuan Zhanjie Qin Qianhui Ren Xueming Teng | 2019 | Geoscience Frontiers2019，10，1： | 0 |
| 20 | Diffusion effect on the decay of time-resolved photoluminescence under low illumination in lead halide perovskites显示文摘Time-resolved photoluminescence(TRPL)has been extensively used to measure the carrier lifetime in lead halide perovskites.The TRPL curves of perovskite materials are usually fitted with a multi-exponential function,instead of a single exponential one.This was considered to be a result of the surface and the bulk recombination or the additional radiative recombination caused by the high excited carrier density.Here,a new model considering the diffusion and the trap-assisted recombination of carriers is proposed to explain the TRPL curves.The expressions of the TRPL curves and the transient absorption(TA)dynamic curves are theoretically derived,demonstrating that the TRPL curve is an infinite exponential series,regardless of the presence of surface recombination or not.Our newly developed highly sensitive nanosecond TA and TRPL were employed to measure the carrier dynamics of the same sample under low illumination in the linear response region of TA,thereby experimentally verifying our model.These results suggest that the decay of the TRPL is not only a consequence of the carrier recombination but also the carrier diffusion.TRPL cannot provide a direct measurement of the carrier lifetime,whereas TA spectroscopy can.Furthermore,the surface and the bulk recombination can be resolved and the average diffusion coefficient(D)can also be correctly obtained by combining TRPL and TA measurements.We also propose an approximate method for calculating the carrier lifetime and diffusion coefficient of high-quality perovskite films.Our model provides not only a new interpretation of the dynamics of the PL decay but also a deep insight into the carrier dynamics in the nanosecond time scale under working condition of perovskites solar cells. | Huang Li Haipeng Di Xingan Wang Zefeng Ren Ming Lu An-An Liu Xueming Yang Nanlin Wang Yiying Zhao Bohan Li | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，8： | 0 |
