| 1 | Source and composition of sedimentary organic matter in the head of Three Gorges Reservoir: a multiproxy approach using δ^(13)C,lignin phenols, and lipid biomarker analyses显示文摘A multiproxy approach including bulk organic carbon, δ^(13) C, lignin phenols, and lipid biomarker analyses were applied to characterize the source and composition of sedimentary organic matter in the head part of Three Gorges Reservoir. OM consisted of both natural(autochthonous and allochthonous) and anthropogenic inputs.The natural OM included input from vascular plants,especially non-woody angiosperms. The allochthonous input included plankton and microbial production, likely due to localized eutrophication. Anthropogenic inputs likely derived from petroleum input and/or urban activities.Other anthropogenic inputs were untreated sewage waste.These influences were concluded to be regionally specific point sources of pollution based on relative distributions and on the fact that molecular characteristics of sedimentary OM were not distributed smoothly along a gradient. | He Ding Changfeng Zhu Kai Zhang Shangbin Xiao Xingqian Cui Yongge Sun | 2017 | Acta Geochimica2017，36，3： | 4 |

| 3 | Optical investigations reveal the effects of 2-aminoethyldiphenyl borate on STIM1 puncta formation显示文摘2-A minoethyldiphenyl borate(2-APB)is the most commonly used pharmacological agent in the study of calcium release-activated channels(CRACa);however,its inhibitory mechanism to CRACs remains unclear.To address this issue,we systematically employed confocal imaging,dual-wavelength excitation photometry and FRET to examine the effects of 2-APB on the dynamic activities and function of STIM1 and Orail,two key components of CRACs.Imaging results support that there are two signaling pathways(Orail-independent and Orail-dependent)for the formation of STM1 puncta.2 APB could dose dependently block Orail-independent but not Oril-dependent STIM1 puncta formation,despite its obvious inhibition effect on store-opented Ca^(2+)entry(SOCE).In addition,we found that although 2-APB could not visibly alter near plasma membrane CAD-eYFP localization,it could completely block CAD-YFP-induced constitutive Ca^(2+)entry and promnote the interaction between Orail and CAD by FRET mea-surements.Therefore,we proposed that inhibitory action of 2-APB on SOCE might attribute to its direct inhbitory effects on Orail channel itself,but not the interference on puncta formation between STIM1 and Orail. | Tao Yu Shangbin Chen Jingying Pan Conglin Su Jun He | 2018 | Journal of Innovative Optical Health Sciences2018，，2： | 0 |
| 4 | Responses of nitrogen cycling and related microorganisms to brackish wetlands formed by evapotranspiration显示文摘Elevated evapotranspiration due to warmer air temperature could raise salinity and nutrient levels of some inland wetlands, potentially impacting nitrogen cycling. To characterize the impact of high evapotranspiration on soil microbial nitrogen cycling in inland wetlands, we compared freshwater and brackish marsh(or non-marsh) wetlands in terms of sediment ammonia-oxidizing rate(AOR), denitrifying rate(DR), and related microbial communities in a typical inland basin, the Hulun Lake basin, in China. Results showed that marsh ecosystems(ME) exhibited 31% higher AOR and 65% higher DR than non-marsh ecosystems(NE). For NE, freshwater non-marsh wetland exhibited 12% higher AOR than brackish non-marsh wetland. This was probably due to the inhibitory effects of high NH_4~+ and salinity levels on ammonia-oxidizing archaea in brackish non-marsh wetland. Conversely, DR in brackish non-marsh wetland was 23% higher than that in freshwater non-marsh wetland, with total organic carbon(TOC) significantly influencing this difference,suggesting that the higher DR in brackish non-marsh wetland was mainly due to its higher TOC level. For ME, due to the direct and indirect interference of salinity, brackish marsh wetland displayed 26% lower AOR and 19% lower DR than freshwater marsh wetland. Besides, brackish wetlands harbored distinct ammonia-oxidizing and denitrifying microbial communities compared to freshwater wetlands. The assembly of these communities was dominated by stochastic processes, while brackish wetlands exhibited more prominent deterministic processes than freshwater wetlands. Overall, high evapotranspiration altered activities and community characteristics of ammonia oxidizers and denitrifiers in inland brackish wetlands by enhancing salinity and nutrient levels,while emergent plants occurring in ME could mitigate the adverse effects of salt stress of inland brackish wetlands on nitrogen cycling. | Jiaohui FANG Tianshu LU Jian LIU Shangbin HE Xiufeng YANG Huashan DOU Honghai ZHANG | 2024 | Pedosphere2024，34，1： | 0 |
