| 1 | Cenozoic sedimentary records and geochronological constraints of differential uplift of the Qinghai-Tibet Plateau显示文摘Geological mapping data (1:250000) in the Qinghai-Tibet Plateau and its adjacent regions reveal the sediment sequences, distribution and tectonic evolution of the 92 Tertiary remnant basins. Southern Tibet and the Yecheng area in Xinjiang, located at southern and northwestern margins of the Qinghai-Tibet Plateau, respectively, were parts of the Neo-Tethys remnant sea in the Paleogene. In southern Tibet, both the subabyssal and abyssal sequences occur at the Gyangze, Saga, Guoyala, and Sangmai areas. The deep-water facies successions outcrop in the west, whereas the shallow-water facies sequences in the east, indicating the east to the west retreat of the Neo-Tethys Ocean. The retreat of the Neo-Tethys Ocean in the east was contributed to the earlier tectonic uplift of the eastern Qinghai-Tibet Plateau. The uplift process of the Plateau from the Late Cretaceous to Pliocene is described as follows: During the Late Cretaceous, tectonic uplift of the Qinghai-Tibet Plateau occurred in the northeastern part and the configuration of the Qinghai-Tibet Plateau was characterized by rise in the northeast and depression in the west. In the Paleocene-Eocene interval, the Tengchong-Baingoin and Kuyake-Golmud areas experienced local tectonic uplifting, the West Kunlun uplift zone broadened easterly, the Qilian uplift zone broadened southerly, and the Songpan-Garzê uplift zone shrank easterly. The Oligocene configuration of the Qinghai-Tibet Plateau was characterized by mountain chains rising along its margins and sedimentary basins in the central part because of tectonic uplifts of the Gangdisê and the Himalaya blocks. Meanwhile, the Kunlun-Altyn-Qilian uplift zones have also broadened southerly and northerly. In contrast, the great uplift zones of the Gangdisê, the Himalaya, the Karakorum, and the Kunlun blocks characterize the paleogeographic contours of the Qinghai-Tibet Plateau during the Miocene-Pliocene. Additionally, the thermochronological data on tectonic uplift events in southern Tibet, West Kunlun Mountains, Altyn Tagh, eastern Tibet, and western Sichuan all suggest that the most intense deformation occurred at 13-8 Ma and since 5 Ma, respectively, corresponding to two great uplift periods in Neogene. As a result, turnover of paleogeographic configuration of the Qinghai-Tibet Plateau occurred during the Neogene, experiencing a change from high contours in the east in the pre-Oligocene to high contours in the west at the end-Pliocene. The uplift of the Qinghai-Tibet Plateau during the Cenozoic was episodic, and the uplifts of various blocks within the Plateau were spatially and chronologically different. | ZHANG KeXin WANG GuoCan CAO Kai LIU Chao XIANG ShuYuan HONG HanLie KOU XiaoHu XU YaDong CHEN FenNing MENG YanNing CHEN RuiMing | 2008 | Science China Earth Sciences2008,51,11: | 31 |
| 2 | Ge-Gen Decoction attenuates oxytocin-induced uterine contraction and writhing response: potential application in primary dysmenorrhea therapy显示文摘The uterine tetanic contraction and uterine artery blood flow reduction are possible reasons for primary dysmenorrhea(PD). In the present study, we aimed to evaluate the uterine relaxant effect and the influence on uterine artery blood velocity of Ge-Gen Decoction(GGD), a well-known Chinese herbal formula. In female ICR mice, uterine contraction was induced by oxytocin exposure following estradiol benzoate pretreatment, and the uterine artery blood velocity was detected by Doppler ultrasound. Histopathological examination of the uterine tissue samples were performed by H&E staining. Ex vivo studies demonstrated that oxytocin, posterior pituitary, or acetylcholine induced contractions in isolated mouse uterus. GGD inhibited both spontaneous and stimulated contractions. In vivo study demonstrated that GGD significantly reduced oxytocin-induced writhing responses with a maximal inhibition of 87%. Further study demonstrated that GGD normalized oxytocin-induced abnormalities of prostaglandins F_2 alpha(PGF_(2α)) and Ca^(2+) in mice. In addition, injection of oxytocin induced a decrease in uterine artery blood flow velocity. Pretreatment with GGD reversed the oxytocin response on blood flow velocity. Histopathological examination showed pretreatment with GGD alleviated inflammation and edema in the uterus when compared with the model group. Both ex vivo and in vivo results indicated that GGD possessed a significant spasmolytic effect on uterine tetanic contraction as well as improvement on uterine artery blood velocity which may involve PGF_(2α) and Ca^(2+) signaling, suggesting that GGD may have a clinic potential in PD therapy. | YANG Lu CHAI Cheng-Zhi YUE Xin-Yi YAN Yan KOU Jun-Ping CAO Zheng-Yu YU Bo-Yang | 2016 | Chinese Journal of Natural Medicines2016,14,2: | 17 |
| 3 | Advances in the pharmacological activities and mechanisms of diosgenin显示文摘Diosgenin, a well-known steroid sapogenin derived from plants, has been used as a starting material for production of steroidal hormones. The present review will summarize published literature concerning pharmacological potential of diosgenin, and the underlying mechanisms of actions. Diosgenin has shown a vast range of pharmacological activities in preclinical studies. It exhibits anticancer, cardiovascular protective, anti-diabetes, neuroprotective, immunomodulatory, estrogenic, and skin protective effects, mainly by inducing apoptosis, suppressing malignant transformation, decreasing oxidative stress, preventing inflammatory events, promoting cellular differentiation/proliferation, and regulating T-cell immune response, etc. It interferes with cell death pathways and their regulators to induce apoptosis. Diosgenin antagonizes tumor metastasis by modulating epithelial-mesenchymal transition and actin cytoskeleton to change cellular motility, suppressing degradation of matrix barrier, and inhibiting angiogenesis. Additionally, diosgenin improves antioxidant status and inhibits lipid peroxidation. Its anti-inflammatory activity is through inhibiting production of pro-inflammatory cytokines, enzymes and adhesion molecules. Furthermore, diosgenin drives cellular growth/differentiation through the estrogen receptor(ER) cascade and transcriptional factor PPARγ. In summary, these mechanistic studies provide a basis for further development of this compound for pharmacotherapy of various diseases. | CHEN Yan TANG You-Mei YU Su-Lan HAN Yu-Wei KOU Jun-Ping LIU Bao-Lin YU Bo-Yang | 2015 | Chinese Journal of Natural Medicines2015,13,8: | 14 |
| 4 | Genesis of the Wulong gold deposit,Liaoning Province,NE China:Constrains from noble gases,radiogenic and stable isotope studies显示文摘TheWulong lode deposit contains over 80 tonnes of gold with an average grade of 5.35 g/t.It is one of the largest deposits in Dandong City,Liaoning Province in northeast China.Previous studies on the deposit focused on its geological characteristics,geochemistry,fluid inclusions,and the timing of gold mineralization.However,controversy remains regarding the origin of the ore-forming fluids and metals,and the genesis of the gold deposit.This paper presents zircon UePb and pyrite RbeSr ages and S,Pb,He,and Ar isotopic results along with quartz H and O isotopic data for all litho-units associated with the deposit.Laser ablation inductively coupled mass spectrometry measurements yielded zircon UePb dates for samples of pre-mineralization rocks like granite porphyry dike,the Sanguliu granodiorite,fine-grained diorite,and syn-mineralization diorite,as well as post-mineralization dolerite,and lamprophyre;their emplacement ages are 1261 Ma,1241 Ma,1231 Ma,1201 Ma,1192 Ma,and 1152 Ma,respectively.The pyrite RbeSr isochron age is 1191 Ma,indicating that both magmatism and mineralization occurred during the Early Cretaceous.The d18OH2O values of ore-forming hydrothermal fluids from the quartzepolymetallic sulfide vein stage vary from 4.8&to 6.5&,and the dDV-SMOW values are between67.7&and75.9&,indicating that the ore-forming fluids were primarily magmatic.The noble gas isotope compositions of fluid inclusions hosted in pyrite suggest that the ore-forming fluids were dominantly derived from crustal sources with minor mantle input.Sulfur isotopic values of pyrite vary between 0.2&and 3.5&,suggesting that S was derived from a homogeneous magmatic source or possibly from fluids derived from the crust.The Pb isotopic compositions of sulfides(207Pb/204Pb?15.51 e15.71,206Pb/204Pb?17.35e18.75,208Pb/204Pb?38.27e40.03)indicate that the Pb of the Wulong gold deposit is a mixture of crust and mantle components.Geochronological and geochemical data,together with the regional geological history,indicate that Early Cretaceous magmatism and mineralization of the Wulong gold deposit occurred during the rollback of the subducting Paleo-Pacific Plate,which resulted in lithospheric thinning and the destruction of the North China Craton(NCC),which indicates that the deposit is of magmaticehydrothermal origin. | Peng Zhang Linlin Kou Yan Zhao Zhongwei Bi Deming Sha Renping Han Zhumin Li | 2020 | Geoscience Frontiers2020,11,2: | 13 |
| 5 | Luteolin alleviates cognitive impairment in Alzheimer’s disease mouse model via inhibiting endoplasmic reticulum stress-dependent neuroinflammation显示文摘Luteolin is a flavonoid in a variety of fruits,vegetables,and herbs,which has shown anti-inflammatory,antioxidant,and anti-cancer neuroprotective activities.In this study,we investigated the potential beneficial effects of luteolin on memory deficits and neuroinflammation in a triple-transgenic mouse model of Alzheimer’s disease(AD)(3×Tg-AD).The mice were treated with luteolin(20,40 mg·kg−1·d−1,ip)for 3 weeks.We showed that luteolin treatment dose-dependently improved spatial learning,ameliorated memory deficits in 3×Tg-AD mice,accompanied by inhibiting astrocyte overactivation(GFAP)and neuroinflammation(TNF-α,IL-1β,IL-6,NO,COX-2,and iNOS protein),and decreasing the expression of endoplasmic reticulum(ER)stress markers GRP78 and IRE1αin brain tissues.In rat C6 glioma cells,treatment with luteolin(1,10µM)dose-dependently inhibited LPS-induced cell proliferation,excessive release of inflammatory cytokines,and increase of ER stress marker GRP78.In conclusion,luteolin is an effective agent in the treatment of learning and memory deficits in 3×Tg-AD mice,which may be attributable to the inhibition of ER stress in astrocytes and subsequent neuroinflammation.These results provide the experimental basis for further research and development of luteolin as a therapeutic agent for AD. | Jie-jian Kou Jun-zhuo Shi Yang-yang He Jiao-jiao Hao Hai-yu Zhang Dong-mei Luo Jun-ke Song Yi Yan Xin-mei Xie Guan-hua Du Xiao-bin Pang | 2022 | Acta Pharmacologica Sinica2022,43,4: | 6 |
| 6 | Development of SNP markers using RNA-seq technology and tetraprimer ARMS-PCR in sweetpotato显示文摘The information of single nucleotide polymorphisms(SNPs) is quite unknown in sweetpotato. In this study,two sweetpotato varieties(Xushu 18 and Xu 781) were sequenced by Illumina technology,as well as de novo transcriptome assembly,functional annotation,and in silico discovery of potential SNP molecular markers. Tetra-primer Amplification Refractory Mutation System PCR(ARMS-PCR) is a simple and sufficient method for detecting different alleles in SNP locus. Total 153 sets of ARMS-PCR primers were designed to validate the putative SNPs from sequences. PCR products from 103 sets of primers were different between Xu 781 and Xushu 18 via agarose gel electrophoresis,and the detection rate was 67.32%. We obtained the expected results from 32 sets of primers between the two genotypes. Furthermore,we ascertained the optimal annealing temperature of 32 sets of primers. These SNPs might be used in genotyping,QTL mapping,or marker-assisted trait selection further in sweetpotato. To our knowledge,this work was the first study to develop SNP markers in sweetpotato by using tetra-primer ARMS-PCR technique. This method was a simple,rapid,and useful technique to develop SNP markers,and will provide a potential and preliminary application in discriminating cultivars in sweetpotato. | KOU Meng XU Jia-lei LI Qiang LIU Ya-ju WANG Xin TANG Wei YAN Hui ZHANG Yun-gang MA Dai-fu | 2017 | Journal of Integrative Agriculture2017,16,2: | 6 |
| 7 | High-performance sandwiched hybrid solid electrolytes by coating polymer layers for all-solid-state lithium-ion batteries显示文摘Poly(vinylidenefluoride-co-hexafluoropropylene)(P(VDF-HFP))/Li_(1.3)Al_(0.3)Ti_(1.7)(PO_(4))_(3)(LATP)/P(VDFHFP) sandwiched hybrid solid electrolytes were precisely tailored and successfully fabricated to assemble into allsolid-state lithium-ion batteries,which were systematically evaluated on microstructure,morphology,thermal stability and electrochemical performance.The sandwiched hybrid solid electrolytes can achieve intimate contact with cathode and anode electrodes to present an excellent interfacial stability.Furthermore,the sandwiched hybrid solid electrolytes possess flexible surface,wide electrochemical working window of 4.7 V,high ionic conductivity of 0.763 mS·cm^(-1) and high thermal stability of 460℃,which may contribute to realizing the practical application in all-solid-state lithium-ion batteries.The assembled cells with the hybrid solid electrolytes can quickly stabilize at a specific discharge capacity of 145.4 mAh·g^(-1) at 0.1 C after only 5 cycles and present admirable rate performance.In addition,morphology characterizations of the sandwiched hybrid solid electrolytes after long-term cycles show a relatively integrated structure coating with a compact LATP layer.The investigations afford a promising strategy that the sandwiched hybrid solid electrolytes can overcome the mechanical limitations of the interface between electrodes and inorganic solid electrolytes to provide favorable properties for all-solid-state lithium-ion batteries. | Zhi-Yan Kou Yan Lu Chang Miao Jie-Qiong Li Cheng-Jin Liu Wei Xiao | 2021 | Rare Metals2021,40,11: | 5 |

| 9 | Warm temperature compromises JA-regulated basal resistance to enhance Magnaporthe oryzae infection in rice显示文摘Changes in global temperatures profoundly affect the occurrence of plant diseases.It is well known that rice blast can easily become epidemic in relatively warm weather.However,the molecular mechanism remains unclear.In this study,we show that enhanced blast development at a warm temperature(22C)compared with the normal growth temperature(28C)is rice plant-determined.Comparative transcriptome analysis revealed that jasmonic acid(JA)biosynthesis and signaling genes in rice could be effectively induced by Magnaporthe oryzae at 28C but not at 22C.Phenotypic analyses of the osaoc1 and osmyc2 mutants,OsCOI1 RNAi lines,and OsMYC2-OE plants further demonstrated that compromised M.oryzaeinduced JA biosynthesis and signaling lead to enhanced blast susceptibility at the warm temperature.Consistent with these results,we found that exogenous application of methyl jasmonate served as an effective strategy for improving blast resistance under the warm environmental conditions.Furthermore,decreased activation of JA signaling resulted in the downregulated expression of some key basal resistance genes at 22C when compared with 28C.Among these affected genes,OsCEBiP(chitin elicitorbinding protein precursor)was found to be directly regulated by OsMYB22 and its interacting protein OsMYC2,a key component of JA signaling,and this contributed to temperature-modulated blast resistance.Taken together,these results suggest that warm temperature compromises basal resistance in rice and enhances M.oryzae infection by reducing JA biosynthesis and signaling,providing potential new strategies for managing rice blast disease under warm climate conditions. | Jiehua Qiu Junhui Xie Ya Chen Zhenan Shen Huanbin Shi Naweed I.Naqvi Qian Qian Yan Liang Yanjun Kou | 2022 | Molecular Plant2022,15,4: | 5 |

| 11 | Improving the performance of all-solid-state supercapacitors by modifying ionic liquid gel electrolytes with graphene nanosheets prepared by arc-discharge显示文摘Ionic liquid gel polymers have widely been used as the electrolytes in all-solid-state supercapacitors,but they suffer from low ionic conductivity and poor electrochemical performance.Arc discharge is a fast,low-cost and scalable method to prepare multi-layered graphene nanosheets,and as-made graphene nanosheets(denoted as ad-GNSs) with few defects,high electrical conductivity and high thermal stability should be favorable conductive additive materials.Here,a novel ionic liquid gel polymer electrolyte based on an ionic liquid(EMIMNTF_2) and an copolymer(P(VDF-HFP)) was modified by the addition of ad-GNSs as an ionic conducting promoter.This modified gel electrolyte shows excellent thermal stability up to 400℃ and a wide electrochemical window of 3 V.An all-solid-state supercapacitor based on commercial activated carbon was fabricated using this modified ionic liquid gel polymer electrolyte,which shows obviously improved electrochemical behaviors compared with those of the corresponding all-solid-state supercapacitor using pure ionic liquid gel polymer electrolyte.Specially,smaller internal resistance,higher specific capacitance,better rate performance and cycling stability are achieved.These results indicate that the ionic liquid gel polymers modified by ad-GNSs would be promising and suitable gel electrolytes for high performance all-solid-state electrochemical devices. | Min-Jie Shi Sheng-Zhong Kou Bao-Shou Shen Jun-Wei Lang Zhi Yang Xing-Bin Yan | 2014 | Chinese Chemical Letters2014,25,6: | 4 |
| 12 | A combination of four effective components derived from Sheng-mai san attenuates hydrogen peroxide-induced injury in PC12 cells through inhibiting Akt and MAPK signaling pathways显示文摘The present study was designed to investigate whether a combination of four effective components derived from Sheng-mai san(SMXZF; ginsenoside Rb1: ginsenoside Rg1: DT^(–1)3: Schizandrol A as 6 : 9 : 4 : 5) could attenuate hydrogen peroxide(H_2O_2)-induced injury in PC12 cells, focusing on the Akt and MAPK pathways. The PC12 cells were exposed to H_2O_2(400 mmol·L^(–1)) for 1 h in the presence or absence of SMXZF pre-treatment for 24 h. Cell viability was measured by MTT assay. The efflux of lactate dehydrogenase(LDH), the intracellular content of malondialdehyde(MDA), the activities of superoxide dismutase(SOD), and caspase-3 were also determined. Cell apoptosis was measured by Hoechst 33342 staining and Annexin V-FITC/PI staining method. The expression of Bcl-2, Bax, cleaved caspase-3, Akt, and MAPKs were detected by Western blotting analyses. SMXZF pretreatment significantly increased the cell viability and SOD activity and improved the cell morphological changes, while reduced the levels of LDH and MDA at the concentrations of 0.1, 1 and 10 μg·m L^(–1). SMXZF also inhibited H_2O_2-induced apoptosis in PC12 cells. Moreover, SMXZF reduced the activity of caspase-3, up-regulated the protein ratio of Bcl-2 and Bax and inhibited the expression of cleaved caspase-3, p-Akt, p-p38, p-JNK and p-ERK1/2 in H_2O_2-induced PC12 cells. Co-incubation of Akt inhibitor or p38 inhibitor partly attenuated the protection of SMXZF against H_2O_2-injured PC12 cells. In conclusion, our findings suggested that SMXZF attenuated H_2O_2-induced injury in PC12 cells by inhibiting Akt and MAPKs signaling pathways, which might shed insights on its neuroprotective mechanism. | CAO Guo-Sheng LI Shao-Xia WANG Yan XU Ying-Qiong LV Yan-Ni KOU Jun-Ping YU Bo-Yang | 2016 | Chinese Journal of Natural Medicines2016,14,7: | 4 |

| 14 | Sheng-Mai-San attenuates contractile dysfunction and structural damage induced by chronic intermittent hypoxia in mice显示文摘Sheng-Mai-San(SMS), a well-known Chinese medicinal plant formula, is widely used for the treatment of cardiac diseases characterized by deficiency of Qi and Yin syndrome. A mouse chronic intermittent hypoxia(CIH) model was established to mimic the primary clinical features of deficiency of Qi and Yin syndrome. Mice experienced CIH for 28 days(nadir 7% to peak 8% oxygen, 20 min per day), resulting in left ventricle(LV) dysfunction and structure abnormalities. After administration of SMS(0.55, 1.1, and 5.5 g·kg-1·d-1) for four weeks, improved cardiac function was observed, as indicated by the increase in the ejection fraction from the LV on echocardiography. SMS also preserved the structural integrity of the LV against eccentric hypotrophy, tissue vacuolization, and mitochondrial injury as measured by histology, electron microscopy, and ultrasound assessments. Mechanistically, the antioxidant effects of SMS were demonstrated; SMS was able to suppress mitochondrial apoptosis as indicated by the reduction of several pro-apoptotic factors(Bax, cytochrome c, and cleaved caspase-3) and up-regulation of the anti-apoptosis factor Bcl-2. In conclusion, these results demonstrate that SMS treatment can protect the structure and function of the LV and that the protective effects of this formula are associated with the regulation of the mitochondrial apoptosis pathway. | MO Wei-Lan CHAI Cheng-Zhi KOU Jun-Ping YAN Yong-Qing YU Bo-Yang | 2015 | Chinese Journal of Natural Medicines2015,13,10: | 3 |
| 15 | Ipomoea batatas HKT1 transporter homolog mediates K^+ and Na^+ uptake in Saccharomyces cerevisiae显示文摘Soil salinity causes the negative effects on the growth and yield of crops. In this study,two sweet potato(Ipomoea batatas L.) cultivars,Xushu 28(X-28) and Okinawa 100(O-100),were examined under 50 and 100 mmol L^(–1) Na Cl stress. X-28 cultivar is relatively high salt tolerant than O-100 cultivar. Interestingly,real-time quantitative polymerase chain reaction(RT-q PCR) results indicated that sweet potato high-affinity K^+ transporter 1(IbHKT1) gene expression was highly induced by 50 and 100 mmol L^(–1) Na Cl stress in the stems of X-28 cultivar than in those of O-100 cultivar,but only slightly induced by these stresses in the leaves and fibrous roots in both cultivars. To characterize the function of IbHKT1 transporter,we performed ion-flux analysis in tobacco transient system and yeast complementation. Tobacco transient assay showed that IbHKT1 could uptake sodium(Na^+). Yeast complementation assay showed that IbHKT1 could take up K^+ in 50 mmol L^(–1) K^+ medium without the presence of Na Cl. Moreover,Na^+ uptake significantly increased in yeast overexpressing IbHKT1. These results showed that IbHKT1 transporter could have K^+-Na^+ symport function in yeast. Therefore,the modes of action of IbHKT1 in transgenic yeast could differ from the mode of action of the other HKT1 transporters in class I. Potentially,IbHKT1 could be used to improve the salt tolerance nature in sweet potato. | PARK Sung-chul YU Yi-cheng KOU Meng YAN Hui TANG Wei WANG Xin LIU Ya-ju ZHANG Yun-gang KWAK Sang-soo MA Dai-fu SUN Jian LI Qiang | 2017 | Journal of Integrative Agriculture2017,16,10: | 3 |
| 16 | Amyloid precursor protein and growth-associated protein 43 expression in brain white matter and spinal cord tissues in a rat model of experimental autoimmune encephalomyelitis显示文摘Studies have demonstrated that amyloid precursor protein(APP)expression increases in multiple sclerosis tissues during acutely and chronically active stages.To determine the relationship between axonal injury and regeneration in multiple sclerosis,an animal model of experimental autoimmune encephalomyelitis was induced using different doses of myelin basic protein peptide.APP and growth-associated protein 43(GAP-43),which is considered a specific marker of neural regeneration,were assessed by western blot analysis.Expression of APP and GAP-43,as well as the correlation between these two proteins,in brain white matter and spinal cord tissues of experimental autoimmune encephalomyelitis rats at different pathological stages was analyzed.Results showed that APP and GAP-43 expression increased during the acute stage and decreased during remission,with a positive correlation between APP and GAP-43 expression in brain white matter and spinal cord tissues.These results suggest that APP and GAP-43 could provide nutritional and protective effects on damaged neurons. | Yizhou Wang Shuang Kou Jingcheng Tang Ping Zhang Qiuxia Zhang Yan Liu Qi Zheng Hui Zhao Lei Wang | 2011 | Neural Regeneration Research2011,6,2: | 3 |
| 17 | Improving Airgun Signal Detection with Small-Aperture Seismic Array in Yunnan显示文摘Repeating airgun sources are eco-friendly sources for monitoring the changes in the physical properties of subsurface mediums,but their signals decay quickly and are buried in the noises soon after traveling short distances.Stacking waveforms from different airgun shots recorded by a single seismic station(shot stacking)is the most popular technique to detect weak signals from noisy backgrounds,and has been widely used to process the data of Fixed Airgun Signal Transmission Stations(FASTS)in China.However,shot stacking sacrifices the time resolution in monitoring to recover a qualified airgun signal by stacking many shots at distance stations,and also suffers from persistent local noises.In this paper,we carried out several small-aperture seismic array experiments around the Binchuan FAST Station(BCFASTS)in Yunnan Province,China,and applied the array technique to improve airgun signal detection.The results show that seismic array processing combining with shot stacking can suppress seismic noises more efficiently,and provide better signal-to-noise ratio(SNR)and coherent airgun signals with less airgun shots.This work suggests that the array technique is a feasible and promising tool in FAST to increase the time resolution and reduce noise interference on routine monitoring. | WANG Weijun ZHOU Qingyun KOU Huadong LIU Guiping ZHU Hongbo YAN Kun | 2019 | Earthquake Research in China2019,33,2: | 3 |
| 18 | The Functional Roles of Lipid Rafts in T Cell Activation,Immune Diseases and HIV Infection and Prevention显示文摘The first appearance of lipid rafts,or lipid rafts-like structure,was occasionally observed by cryo-electronic microscopy in 1980s as cavity,such as caveolae. However,the fully understanding of lipid raft was attributed by the studies of T cell activation,virus entry/budding,and other membrane events. During the interaction of T cell and antigen presenting cell,a highly organized structure is formed at the interface of the two cells,where cholesterol and sphingolipids are enriched,and form a liquid ordered phase that facilitates the signaling proteins on and off. Lipid rafts are also involved in virus entry and assembly. In this review,we will discuss cholesterol-sphingolipid floating microdomain,the lipid raft as a unique compartment of the plasma membrane,with biological functions that ensure correct intracellular traffic of proteins and lipids,such as protein-protein interactions by concentrating certain proteins in these microdomains,while excluding others. We also discuss the disruption of lipid rafts is related to different diseases and aging,and we especially exploit the lipid rafts as pharmaceutical targets for anti-virus and anti-inflammation,particularly a new approach to control HIV infection for AIDS prevention and protection by inhibition or disruption of lipid rafts. | Cheng Luo Kou Wang Dequan Liu Yan Li Qinshi Zhao | 2008 | Cellular & Molecular Immunology2008,5,1: | 3 |

| 20 | Low phosphorus promotes NSP1–NSP2 heterodimerization to enhance strigolactone biosynthesis and regulate shoot and root architecture in rice显示文摘Phosphorus is an essential macronutrient for plant development and metabolism,and plants have evolved ingenious mechanisms to overcome phosphate(Pi)starvation.However,the molecular mechanisms underlying the regulation of shoot and root architecture by low phosphorus conditions and the coordinated utilization of Pi and nitrogen remain largely unclear.Here,we show that Nodulation Signaling Pathway 1(NSP1)and NSP2 regulate rice tiller number by promoting the biosynthesis of strigolactones(SLs),a class of phytohormones with fundamental effects on plant architecture and environmental responses.We found that NSP1 and NSP2 are induced by Oryza sativa PHOSPHATE STARVATION RESPONSE2(OsPHR2)in response to low-Pi stress and form a complex to directly bind the promoters of SL biosynthesis genes,thus markedly increasing SL biosynthesis in rice.Interestingly,the NSP1/2–SL signaling module represses the expression of CROWN ROOTLESS 1(CRL1),a newly identified early SL-responsive gene in roots,to restrain lateral root density under Pi deficiency.We also demonstrated that GR24^(4DO) treatment under normal conditions inhibits the expression of OsNRTs and OsAMTs to suppress nitrogen absorption but enhances the expression of OsPTs to promote Pi absorption,thus facilitating the balance between nitrogen and phosphorus uptake in rice.Importantly,we found that NSP1p:NSP1 and NSP2p:NSP2 transgenic plants show improved agronomic traits and grain yield under low-and medium-phosphorus conditions.Taken together,these results revealed a novel regulatory mechanism of SL biosynthesis and signaling in response to Pi starvation,providing genetic resources for improving plant architecture and nutrient-use efficiency in low-Pi environments. | Kun Yuan Hao Zhang Chaoji Yu Nan Luo Jijun Yan Shuang Zheng Qingliang Hu Dahan Zhang Liquan Kou Xiangbing Meng Yanhui Jing Mingjiang Chen Xinwei Ban Zongyun Yan Zefu Lu Jian Wu Yu Zhao Yan Liang Yonghong Wang Guosheng Xiong Jinfang Chu Ertao Wang Jiayang Li Bing Wang | 2023 | Molecular Plant2023,16,11: | 2 |
