1Importance of Weighting for Multi-Variable Habitat Suitability Index Model: A Case Study of Winter- Spring Cohort of Ommastrephes bartramii in the Northwestern Pacific Ocean显示文摘Weighting values for different habitat variables used in multi-factor habitat suitability index (HSI) modeling reflect the relative influences of different variables on distribution of fish species. Using the winter-spring cohort of neon flying squid (Ommastrephes bartramii) in the Northwestern Pacific Ocean as an example, we evaluated the impact of different weighting schemes on the HSI models based on sea surface temperature, gradient of sea surface temperature and sea surface height. We compared differences in predicted fishing effort and HSI values resulting from different weighting. The weighting for different habitat variables could greatly influence HSI modeling and should be carefully done based on their relative importance in influencing the resource spatial distribution. Weighting in a multi-factor HSI model should be further studied and optimization methods should be developed to improve forecasting squid spatial distributions.GONG Caixia CHEN Xinjun GAO Feng CHEN Yong 2012Journal of Ocean University of China2012,11,2:11
2A de novo Genome of a Chinese Radish Cultivar显示文摘Here, we report a high-quality draft genome of a Chinese radish(Raphanus sativus) cultivar. This draft contains 387.73 Mb of assembled scaffolds, 83.93% of the scaffolds were anchored onto nine pseudochromosomes and 95.09% of 43 240 protein-coding genes were functionally annotated. 184.75 Mb(47.65%) of repeat sequences was identified in the assembled genome. By comparative analyses of the radish genome against 10 other plant genomes, 2 275 genes in 780 gene families were found unique to R. sativus. This genome is a good reference for genomic study and of great value for genetic improvement of radish.ZHANG Xiaohui YUE Zhen MEI Shiyong QIU Yang YANG Xinhua CHEN Xiaohua CHENG Feng WU Zhangyan SUN Yuyan JING Yi LIU Bo SHEN Di WANG Haiping CUI Na DUAN Yundan WU Jian WANG Jinglei GAN Caixia WANG Jun WANG Xiaowu LI Xixiang 2015Horticultural Plant Journal2015,1,3:10
3Protective effects of acupuncture and LGNHFD on expressions of vascular endothelial growth factor, basic fibroblast growth factor,and cluster of differentiation 34 in rats with cerebral ischemia-reperfusion injury显示文摘OBJECTIVE: To investigate the protective effects of electroacupuncture and LGNHFD on cerebral ischemia-reperfusion injury, and their effects on the expression of cluster of differentiation 34(CD 34), vascular endothelial growth factor(VEGF), and basic fibroblast growth factor(b FGF) in the peripheral tissue of the cerebral ischemic semi-dark zone in rats.The influence and mechanism of expression.METHODS: Healthy male Sprague-Dawley rats were randomly divided into the sham operation group, model group, Traditional Chinese Medicine (TCM) group, electroacupuncture group, and acupuncture group. The cerebral ischemia model was prepared by middle artery occlusion. The electroacupuncture and TCM groups received electroacupuncture at the 'Neiguan(PC6)', 'Baihui(GV20)', and 'Renzhong(GV26)' acupoints from 4 h after modeling, once daily for 14 d. After modeling,the acupuncture and TCM groups were administered LGNHFD once daily for 14 d. After treatment,the infarct volume and regional cerebral blood flow(r CBF) were measured in each group, the expression of CD34 in the surrounding ischemic penumbra was determined using immunohistochemistry,and the expression of angiogenesis-related factors in the ischemic hemisphere was detected by western blot.RESULTS: Compared with the sham operation group, r CBF was significantly decreased(P < 0.01)and cerebral infarction volume was significantly increased(P < 0.01) in the model group at four time points(5 min and 3, 7, and 14 d after modeling). At three postoperative time points(3, 7, and 14 d), the number of CD34 + cells in the model group were significantly increased(P < 0.01), and the relative expression levels of VEGF, b FGF, and CD34+ in the ischemic hemisphere were significantly increased(P < 0.01, P < 0.05). Compared with the model group, the r CBF of the acupuncture group was significantly increased at 3, 7, and 14 d after intervention(P < 0.01), while the r CBF of the electroacupuncture and TCM groups was significantly increased at 7 and 14 d after intervention(P < 0.01).After 3, 7, and 14 d of intervention, infarct volume was significantly reduced(P < 0.01), the number of CD34 + cells was significantly increased(P < 0.01,P < 0.05), and the relative expression levels of VEGF,b FGF, and CD34 in the ischemic hemisphere were significantly increased(P < 0.01, P < 0.05). Compared with the electroacupuncture and TCM groups, the r CBF of the acupuncture group was significantly increased(P < 0.01), the infarct volume was significantly reduced(P < 0.01), and the relative expression levels of VEGF, b FGF, and CD34 were significantly increased(P < 0.05, P < 0.01) after 3, 7,and 14 d of intervention.CONCLUSION: Acupuncture therapy is superior to simple drug and electroacupuncture therapy for reducing infarct volume, increasing r CBF and CD34 expression in cells, and promoting capillary regeneration in rats with cerebral ischemia. This may be related to the increased expression of VEGF, b FGF,and CD34 — which are related to cerebrovascular neovascularization — in the ischemic hemispheres of such rats.YANG Le YANG Baocun ZHANG Caixia TONg Jie FENG Geli XIAO Gaiqin 2021Journal of Traditional Chinese Medicine2021,41,3:8

5Distinct immune signatures discriminate between asymptomatic and presymptomatic SARS-CoV-2^(pos)subjects显示文摘Increasing numbers of SARS-CoV-2-positive(SARS-CoV-2^(pos))subjects are detected at silent SARS-CoV-2 infection stage(SSIS).Yet,SSIS represents a poorly examined time-window wherein unknown immunity patterns may contribute to the fate determination towards persistently asymptomatic or overt disease.Here,we retrieved blood samples from 19 asymptomatic and 12 presymptomatic SARS-COV-2^(pos)subjects,47 age/gender-matched patients with mild or moderate COVID-19 and 27 normal subjects,and interrogated them with combined assays of 44-plex CyTOF,RNA-seq and Olink.Notably,both asymptomatic and presymptomatic subjects exhibited numerous readily detectable immunological alterations,while certain parameters including more severely decreased frequencies of CD107a^(low)classical monocytes,intermediate monocytes,non-classical monocytes and CD62L^(hi)CD8^(+)Tnaive cells,reduced plasma STC1 level but an increased frequency of CD4^(+)NKT cells combined to distinguish the latter.Intercorrelation analyses revealed a particular presymptomatic immunotype mainly manifesting as monocytic overactivation and differentiation blockage,a likely lymphocyte exhaustion and immunosuppression,yielding mechanistic insights into SSIS fate determination,which could potentially improve 5ARS-CoV-2 management.Shanhe Yu Caixia Di Shijun Chen Mingquan Guo Jiayang Yan Zhaoqin Zhu Li Liu Ruixue Feng Yinyin Xie Ruihong Zhang Juan Chen Mengxi Wang Dong Wei Hai Fang Tong Yin Jinyan Huang Saijuan Chen Hongzhou Lu Jiang Zhu Jieming Qu 2021Cell Research2021,31,11:4
6Effect of Spatial and Temporal Scales on Habitat Suitability Modeling:A Case Study of Ommastrephes bartramii in the Northwest Pacific Ocean显示文摘Temporal and spatial scales play important roles in fishery ecology, and an inappropriate spatio-temporal scale may result in large errors in modeling fish distribution. The objective of this study is to evaluate the roles of spatio-temporal scales in habitat suitability modeling, with the western stock of winter-spring cohort of neon flying squid(Ommastrephes bartramii) in the northwest Pacific Ocean as an example. In this study, the fishery-dependent data from the Chinese Mainland Squid Jigging Technical Group and sea surface temperature(SST) from remote sensing during August to October of 2003–2008 were used. We evaluated the differences in a habitat suitability index model resulting from aggregating data with 36 different spatial scales with a combination of three latitude scales(0.5°, 1° and 2°), four longitude scales(0.5°, 1°, 2° and 4°), and three temporal scales(week, fortnight, and month). The coefficients of variation(CV) of the weekly, biweekly and monthly suitability index(SI) were compared to determine which temporal and spatial scales of SI model are more precise. This study shows that the optimal temporal and spatial scales with the lowest CV are month, and 0.5° latitude and 0.5° longitude for O. bartramii in the northwest Pacific Ocean. This suitability index model developed with an optimal scale can be cost-effective in improving forecasting fishing ground and requires no excessive sampling efforts. We suggest that the uncertainty associated with spatial and temporal scales used in data aggregations needs to be considered in habitat suitability modeling.GONG Caixia CHEN Xinjun GAO Feng TIAN Siquan 2014Journal of Ocean University of China2014,13,6:2

8A novel TiO_2 with a large amount of bulk intrinsic defects-Visible-light-responded photocatalytic activity induced by foreign trap显示文摘A novel TiO2 (anatase) containing a large amount of single electron trapped oxygen vacancies (SETOV) was prepared by dehydration of titanic acid nanotubes. This novel TiO2 contains high concentration intrinsic defects in bulk structure, while its surface still remains the stoichiometric structure to protect them. And this novel TiO2 itself has the visible light absorption without any doping, so we call it as the third generation of TiO2 . However, it is regretted that this novel TiO2 (A) only has photocatalytic activity under UV light irradiation, and was inactive for the visible light. The true reasons for this phenomenon were investigated by the transient IR absorption and photoluminescence spectra. Through constructing the foreign electron traps (PdO, PtO2 ), the photocatalytic oxidation of propylene under visible light irradiation was successfully achieved. The removal yield of propylene (C3H6 ) reached 7.6% and 28% on 2 wt.% PtO2 /novel TiO2 and 2 wt.% PdO/novel TiO2 , respectively. By comparison with the noble metal electron traps (Pt, Pd), we found that the effective foreign electron traps need to satisfy two conditions: (1) its work function should situate in the range of Eg(TiO2 ); (2) O2 adsorbes on it undissociatively. This work opens up a new route for the investiga- tion of solar-energy-available TiO2 .LI QiuYe ZHANG JiWei JIN ZhenSheng FENG CaiXia ZHANG JingWei WU ZhiShen ZHANG ZhiJun 2013Chinese Science Bulletin2013,58,14:1

10Dual-active-site Fe/Cu single-atom nanozymes with multifunctional specific peroxidase-like properties for S^(2-)detection and dye degradation显示文摘Designing single-atom nanozymes with densely exposed metal atom active sites and enhancing catalytic activity to detect pollutants remain a serious challenge.Herein,we reported a single-atom nanozyme with layered stacked Fe/Cu dual active sites(Fe/Cu-NC SAzyme)synthesized via hydrothermal and hightemperature pyrolysis using folic acid as a template.Compared with Fe-NC and Cu-NC SAzyme,Fe/Cu-NC SAzyme has higher peroxidase-like activity,which indicates that the doping of synthesized Fe/Cu bimetals can improve the catalytic activity and that the atomic loading of Fe and Cu in Fe/Cu-NC is 5.5 wt%and 2.27 wt%,respectively.When S^(2-)is added to the Fe/Cu-NC catalytic system,a high-sensitivity and high-selectivity S^(2-)colorimetric sensing platform can be established,with a wide linear range(0.09-6μmol/L)and a low detection limit(30 nmol/L),which can be used to detect S^(2-)in environmental water samples.What’s more,the Fe/Cu-NC SAzyme can activate peroxymonosulfate(PMS)to degrade 99.9%of rhodamine B(Rh B)within 10 min with a degradation kinetics of 0.5943 min^(-1).This work details attractive applications in Fe/Cu-NC SAzyme colorimetric sensing and dye degradation.Xiaofang Chen Ya Wang Min Feng Die Deng Xiaoyi Xie Caixia Deng Kashif Nawaz Khattak Xiupei Yang 2023Chinese Chemical Letters2023,34,6:1

12Zircon U-Pb Age,Geochemical,and Sr-Nd-Pb-Hf Isotopic Constraints on the Time Frame and Origin of Early Cretaceous Mafic Dykes in the Wuling Mountain Gravity Lineament,South China显示文摘In view of the importance of mafic dyke swarms and their contribution to current scientific problems relating to South China,herein,we present the findings of studies on twenty–five representative mafic dykes cropping out in Hunan Province and Guangxi Zhuang Autonomous Region,within the southern Wuling Mountain gravity lineament,China.These results include new zircon LA-ICP-MS U-Pb age,whole rock geochemical,Sr-Nd-Pb isotopic,and zircon Hf isotopic data for these dykes.The dykes formed between 131.5±1.2 and 121.6±1.1 Ma,and have typical doleritic textures.They fall into the alkaline and shoshonitic series,are enriched in light rare earth elements(LREE),some large ion lithophile elements(LILE;e.g.,Rb,Ba,and Sr),Th,U,and Pb,and are depleted in Nb,Ta,Hf,and Ti.Moreover,the dolerites have high initial 87 Sr/86 Sr ratios(0.7055–0.7057),negativeεNd(t)and zirconεHf(t)values(-14.8 to-11.9,-30.4 to-14.9),and relatively constant initial Pb isotopic ratios(that are EM1-like,16.77–16.94,15.43–15.47,and 36.84–36.92 for 206 Pb/204 Pb,207 Pb/204 Pb,and 208 Pb/204 Pb,respectively).These results indicate that the dykes were likely derived from magma generated through low-degree partial melting(1.0%–10%)of an EM1-like garnet–lherzolite mantle source.The parental magmas fractionated olivine,clinopyroxene,plagioclase,and Ti-bearing phases with negligible crustal contamination,during ascent and dyke emplacement.Several possible models have been proposed to explain the origin of Mesozoic magmatism along the Wuling Mountain gravity lineament.Herein we propose a reasonable model for the origin of these mafic dykes,involving the collision between the paleo-Pacific Plate and South China,which led to subsequent lithospheric extension and asthenosphere upwelling,resulting in partial melting the underlying mantle lithosphere in the Early Cretaceous,to form the parental magmas to the WMGL mafic dykes,as studied.CHEN Xiaoqing LIU Shen FENG Caixia XU Jingyan ZHAO Huibo FENG Guangying Ian M.COULSON SUN Jinggui FAN Yan 2021Acta Geologica Sinica(English Edition)2021,95,2:1

15MAGI1 inhibits migration and invasion via blocking MAPK/ERK signaling pathway in gastric cancer显示文摘Objective: To explore the association of membrane-associated guanylate kinase inverted 1(MAGI1) with gastric cancer(GC) and the related molecular mechanisms.Methods: The reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry(IHC)were utilized to measure the MAGI1 expression level in GC tissues. Quantitative real-time PCR and Western blotting were used to ensure the MAGI1 expression in GC cell lines. Small hairpin RNA(sh RNA) was applied for knockdown of endogenous MAGI1 in GC cells. MTT assay and colony formation assay, scratch wounding migration assay and transwell chamber migration assay, as well as transwell chamber invasion assay were employed respectively to investigate the GC cell proliferation, migration and invasion in MAGI1-knockdown and control GC cells. The potential molecular mechanism mediated by MAGI1 was studied using Western blotting and RT- PCR.Results: RT-PCR and IHC verified MAGI1 was frequently expressed in matched adjacent noncancerous mucosa compared with GC tissues and the expression of MAGI1 was related to clinical pathological parameters. Functional assays indicated that MAGI1 knockdown significantly promoted GC cell migration and invasion. Further mechanism investigation demonstrated that one pathway of MAGI1 inhibiting migration and invasion was mainly by altering the expression of matrix metalloproteinases(MMPs) and epithelial-mesenchymal transition(EMT)-related molecules via inhibiting MAPK/ERK signaling pathway.Conclusions: MAGI1 was associated with GC clinical pathological parameters and acted as a tumor suppressor via inhibiting of MAPK/ERK signaling pathway in GC.Shuqin Jia Jiajia Lu Tingting Qu Yi Feng Xiaohong Wang Caixia Liu Jiafu Ji 2017Chinese Journal of Cancer Research2017,29,1:1

19Geochronology and Genetic Model for Early Cretaceous Volcanic Rocks from the Southern Qiangtang Terrane,Northern Tibet,China: Constraints from U-Pb Zircon Dating, Whole-Rock Geochemical and Sr-Nd Isotopic Data显示文摘Post-collisional volcanic rocks of Mesozoic age occur in the regions adjacent to Gerze, part of the southern Qiangtang Terrane of northern Tibet, China. Geochronological, geochemical, and wholerock Sr-Nd isotopic analyses were performed on the volcanic rocks to better characterize their emplacement age and models for their origin. Laser ablation-inductively coupled plasma-mass spectrometry(LA-ICP-MS) U-Pb zircon analyses yielded consistent ages ranging from 123.1±0.94 Ma to 124.5±0.89 Ma for six volcanic rocks from the study area. The intermediate volcanic rocks belong to the alkaline and sub-alkaline magma series in terms of K2 O+Na2 O contents(5.9%–9.0%), and to the shoshonitic and calc-alkaline series on the basis of their high K2 O contents(1.4%–3.3%). The Gerze volcanic rocks are characterized by the enrichment of light rare earth elements [(La/Yb)N=34.9–49.5] and large–ion lithophile elements(e.g., Rb, Ba, Th, U, K, Pb, and Sr), slightly negative Eu anomalies(Eu/Eu*=0.19–0.24), and negative anomalies in high field strength elements(e.g., Nb, Ta, Hf and Ti), relative to primitive mantle. The samples show slightly elevated(87 Sr/86 Sr)i values that range from 0.7049 to 0.7057, and low εNd(t) values from-0.89 to-2.89. These results suggest that the volcanic rocks studied derived from a compositionally heterogeneous mantle source and that their parent magmas were basaltic. The more mafic, parental magmas to the Gerze volcanic rocks likely underwent fractional crystallization of clinopyroxene, hornblende, biotite, and potassium feldspar, during ascent, with little to no crustal contamination, prior to their eruption/emplacement. While these volcanic rocks exhibit geochemical signatures typical of magmas formed in a destructive plate-margin setting, it is plausible that their mantle source might also have acquired such characteristics in an earlier episode of subduction.LIU Shen FENG Caixia M.Santosh FENG Guangying XU Mengjing Ian M.COULSON GUO Xiaolei GUO Zhuang FAN Yan 2018Acta Geologica Sinica(English Edition)2018,92,6:1
20Enabling technology and core theory of synthetic biology显示文摘Synthetic biology provides a new paradigm for life science research(“build to learn”)and opens the future journey of biotechnology(“build to use”).Here,we discuss advances of various principles and technologies in the mainstream of the enabling technology of synthetic biology,including synthesis and assembly of a genome,DNA storage,gene editing,molecular evolution and de novo design of function proteins,cell and gene circuit engineering,cell-free synthetic biology,artificial intelligence(AI)-aided synthetic biology,as well as biofoundries.We also introduce the concept of quantitative synthetic biology,which is guiding synthetic biology towards increased accuracy and predictability or the real rational design.We conclude that synthetic biology will establish its disciplinary system with the iterative development of enabling technologies and the maturity of the core theory.Xian-En Zhang Chenli Liu Junbiao Dai Yingjin Yuan Caixia Gao Yan Feng Bian Wu Ping Wei Chun You Xiaowo Wang Tong Si 2023Science China(Life Sciences)2023,66,8:1
