| 1 | Petroleum geology controlled by extensive detachment thinning of continental margin crust: A case study of Baiyun sag in the deep-water area of northern South China Sea显示文摘The relationships between crustal stretching and thinning,basin structure and petroleum geology in Baiyun deep-water area were analyzed using large area 3D seismic,gravity,magnetic,ocean bottom seismic(OBS),deep-water exploration wells and integrated ocean drilling program(IODP).During the early syn-rifting period,deep-water area was a half-graben controlled by high angle faults influenced by the brittle extension of upper crust.In the mid syn-rifting period,this area was a broad-deep fault depression controlled by detachment faults undergone brittle-ductile deformation and differentiated extension in the crust.In the late syn-rifting period,this area experienced fault-sag transition due to saucer-shaped rheology change dominated by crustal ductile deformation.A broad-deep fault depression controlled by the large detachment faults penetrating through the crust is an important feature of deep-water basin.The study suggests that the broad-deep Baiyun sag provides great accommodation space for the development of massive deltaic-lacustrine deposition system and hydrocarbon source rocks.The differentiated lithospheric thinning also resulted in the different thermal subsidence during post-rifting period,and then controlled the development of continental shelf break and deep-water reservoir sedimentary environment.The high heat flow background caused by the strong thinning of lithosphere and the rise of mantle source resulted in particularities in the reservoir diagenesis,hydrocarbon generation process and accumulation of deep-water area in northern South China Sea. | PANG Xiong REN Jianye ZHENG Jinyun LIU Jun YU Peng LIU Baojun | 2018 | Petroleum Exploration and Development2018，45，1： | 1 |

| 5 | Sodium dodecyl sulfate sensitized electrochemical method for subnanomole level determination of ortho-phenylphenol at a novel disposable electrode显示文摘The electrochemical behavior of ortho-phenylphenol(OPP) at a disposable electrode(an improved wax-impregnated graphite electrode) in the presence of sodium dodecyl sulfate(SDS) was studied for the first time.The results demonstrated that the electrocatalytic oxidation process of OPP was accompanied with two-charge-two-proton transference.The electronic transmission coefficient(α) and diffusion coefficient(DR) for OPP were calculated to be 0.8126 and 3.61 × 10-2 cm2/s,respectively.The electrochemical signal was apparently improved by SDS at the disposable electrode and the oxidative peaks current was proportional to the concentration of OPP over the range from 1.0 × 10-9 to 4.0 × 10-6 mol/L with the detection limit of 8.7 × 10-10 mol/L.This novel and highly sensitive method can be successfully applied to detect OPP in the orange rind sample. | LI HongBo LI Jing MENG DongMei PENG JinYun QIAO QiuJu YANG ZhanJun XU Qin HU XiaoYa | 2011 | Science China Chemistry2011，54，7： | 0 |
| 6 | Malignant transformation by oncogenic K-ras requires IDH2-mediated reductive carboxylation to promote glutamine utilization显示文摘Dear Editor,Oncogenic K-ras mutation plays a major role in malignant transformation and induces significant alterations in cancer cell metabolism[1–4].However,the major molecular players mediating metabolic alterations during K-ras-driven cancer development remain elusive.The observations that tumorigenesis often requires multiple hits suggest that K-ras mutation likely needs the coordination of other molecular events that enable adaptive cellular metabolism for a full malignant transformation.Based on our previous study on the impact of K-ras onmitochondrial metabolism[1,5]and our recent findings that mitochondrial isocitrate dehydrogenase 2(IDH2)could promote the“reverse”flow of the tricarboxylic acid(TCA)cycle fromα-KG to isocitrate and enhance the survival and proliferation of acute myeloid leukemia cells[6],we investigated the potential role of IDH2 in metabolic adaptation during K-ras-driven tumorigenesis. | Rui Liu Panpan Liu Huichang Bi Jianhua Ling Huiqin Zhang Mingquan Zhang Yumin Hu Paul J Chiao Peng Huang Jinyun Liu | 2023 | Cancer Communications2023，43，2： | 0 |
| 7 | Growth and Antimony Bioconcentration Characteristics of Wild Ramie(Boehmeria nivea)under Sb Stress in Different Valence States显示文摘[Objectives] To explore the effects of antimony(Sb) in different valence states on the growth and Sb bioconcentration and transfer of wild ramie(Boehmeria nivea). [Methods] A pot experiment was conducted to study the effects of Sb(Ⅲ) and Sb(Ⅴ) stress on plant height, biomass, leaf SPAD value, Sb contents in various organs, Sb bioconcentration and transfer factors, and other indexes. [Results] Both kinds of Sb treatments showed a trend of 'first increasing and then decreasing' in plant height as Sb concentration increased. The plant heights in Sb(Ⅲ) treatments with a concentration lower than 1 000 mg/kg and Sb(Ⅴ) treatments with concentrations lower than 4 000 mg/kg were significantly higher than that of the control check(CK);and the Sb(Ⅲ) treatment of the high concentration(4 000 mg/kg) resulted in a significant decrease in plant height, while the 8 000 mg/kg Sb(Ⅴ) treatment still showed an increase in plant height, indicating that the toxicity of Sb(Ⅴ) to wild ramie was significantly lower than that of Sb(Ⅲ). The Sb(Ⅲ) treatments with a concentration lower than 2 000 mg/kg had little effect on the dry weight of the aboveground part, while the treatment with a higher concentration showed a significant decrease;and the dry weights in various concentrations of Sb(Ⅴ) treatments showed no significant differences, but they were significantly higher than the CK and corresponding concentration of Sb(Ⅲ) treatment. Both types of Sb stress could promote the increase of SPAD value in wild ramie leaves, and the performance was significantly higher than the CK. As the concentration of Sb treatment increased, the Sb content in both the aboveground and underground parts showed a significant increase;and the comparison of Sb content under corresponding concentrations of the two types of Sb treatments showed that in the aboveground part, Sb(Ⅲ) was higher than Sb(Ⅴ), while in the underground part, the opposite was true. The bioconcentration factor(BF) of Sb decreased with the increase of Sb treatment concentration overall, and the value of Sb(Ⅴ) was smaller than that of Sb(Ⅲ), but both kinds of Sb stress were significantly smaller than the CK. The transfer factor(TF) of Sb in wild ramie showed a trend of 'increasing first and then decreasing' with the concentration of Sb treatment, and various treatments of Sb(Ⅲ) were higher than the CK, with significant differences, while among various treatments of Sb(Ⅴ), except treatment B3, the reduction of which was not significant, other Sb(Ⅴ) treatments showed significant decreases. Comparing the two types of Sb treatments, the BF and TF values of Sb in wild ramie under Sb(Ⅲ) treatments were higher than those under Sb(Ⅴ) treatments, and the TF reached a significant level, indicating that the Sb transport ability of wild ramie under Sb(Ⅲ) treatments was stronger. [Conclusions] This study provides a theoretical basis for the mining of wild ramie Sb restoration genes and the application of large-scale cultivation in ecological restoration. | Fulong YANG Jiecheng HAN Yuan WEI Xiaoqi YANG Jinyun PENG Zhi WEI Xiaolian YAN Beiyou ZHANG Qiaoshan LIU Jing ZHOU Guiyuan MENG | 2023 | Asian Agricultural Research2023，15，6： | 0 |
