5Wnt/b-catenin signaling plays an ever-expanding role in stem cell self-renewal,tumorigenesis and cancer chemoresistance显示文摘Wnt signaling transduces evolutionarily conserved pathways which play important roles in initiating and regulating a diverse range of cellular activities,including cell proliferation,calcium homeostasis,and cell polarity.The role of Wnt signaling in controlling cell proliferation and stem cell self-renewal is primarily carried out through the canonical pathway,which is the best-characterized the multiple Wnt signaling branches.The past 10 years has seen a rapid expansion in our understanding of the complexity of this pathway,as many new components of Wnt signaling have been identified and linked to signaling regulation,stem cell functions,and adult tissue homeostasis.Additionally,a substantial body of evidence links Wnt signaling to tumorigenesis of cancer types and implicates it in the development of cancer drug resistance.Thus,a better understanding of the mechanisms by which dysregulation of Wnt signaling precedes the development and progression of human cancer may hasten the development of pathway inhibitors to augment current therapy.This review summarizes and synthesizes our current knowledge of the canonical Wnt pathway in development and disease.We begin with an overview of the components of the canonical Wnt signaling pathway and delve into the role this pathway has been shown to play in stemness,tumorigenesis,and cancer drug resistance.Ultimately,we hope to present an organized collection of evidence implicating Wnt signaling in tumorigenesis and chemoresistance to facilitate the pursuit of Wnt pathway modulators that may improve outcomes of cancers in which Wnt signaling contributes to aggressive disease and/or treatment resistance.Maryam K.Mohammed Connie Shao Jing Wang Qiang Wei Xin Wang Zachary Collier Shengli Tang Hao Liu Fugui Zhang Jiayi Huang Dan Guo Minpeng Lu Feng Liu Jianxiang Liu Chao Ma Lewis L.Shi Aravind Athiviraham Tong-Chuan He Michael J.Lee 2016Genes & Diseases2016,3,1:70

8Meta-analysis of defibrase in treatment of acute cerebral infarction显示文摘Background Fibrinogen-depleting agents are promising in the treatment of cerebral ischemic disease. They were studied by many trials, and the outcomes were different because of different regimens and different doses. In this study, we assessed the efficacy and safety of defibrase on acute cerebral infarction in China. Methods A search using Chinese hospital knowledge database (CHKD) and MEDLINE database for randomized controlled trials was carried out. A CHKD (1994 June 2005) search was performed with the keyword 'defibrase', then a second search for the keyword 'acute cerebral infarction'; a MEDLINE search (1950 June 2005) was performed with the following [(cerebral ischemia), OR (acute cerebral infarction), OR (stroke)], AND [defibrase]. Meta-analysis was performed with RevMan software 4.2. Results Included were 14 studies comparing the efficiency and safety of defibrase with other drugs in the treatment of acute cerebral infarction. Patients’ records were pooled (total 646 patients; defibrase, n=328, no defibrase n=318). Neurological deficit score (NDS) before treatment showed weighted mean differences (WMD)=0.95, 95% confidence interval (CI)= (-0.60, 2.50), P=0.23; NDS after treatment showed WMD=- 2.20, 95% CI= (-4.21, -0.18), P=0.03; Barthel index at 3 months showed WMD=4.45, 95% CI= (-0.13, 9.03), P=0.06; the plasma fibrinogen level before treatment showed WMD=0.02, 95% CI= (-0.16, 0.19), P=0.86; plasma fibrinogen level after treatment showed WMD=-1.51, 95% CI= (-1.88, -1.15), P<0.00 001. Conclusions With the given dose and regimen of defibrase in China, defibrase may play a role of anticoagulation. It might inhibit the progression of stroke and prevent the recurrence of stroke.GUO Yi ZUO Yan-fang WANG Qi-zhang TANG Bing-shan LI Fu-kang SUN Yi 2006Chinese Medical Journal2006,,8:35

13Positioning accuracy assessment for the 4GEO/5IGSO/2MEO constellation of COMPASS显示文摘Determined to become a new member of the well-established GNSS family,COMPASS(or BeiDou-2) is developing its capabilities to provide high accuracy positioning services.Two positioning modes are investigated in this study to assess the positioning accuracy of COMPASS' 4GEO/5IGSO/2MEO constellation.Precise Point Positioning(PPP) for geodetic users and real-time positioning for common navigation users are utilized.To evaluate PPP accuracy,coordinate time series repeatability and discrepancies with GPS' precise positioning are computed.Experiments show that COMPASS PPP repeatability for the east,north and up components of a receiver within China's Mainland is better than 2 cm,2 cm and 5 cm,respectively.Apparent systematic offsets of several centimeters exist between COMPASS precise positioning and GPS precise positioning,indicating errors remaining in the treatments of COMPASS measurement and dynamic models and reference frame differences existing between two systems.For common positioning users,COMPASS provides both open and authorized services with rapid differential corrections and integrity information available to authorized users.Our assessment shows that in open service positioning accuracy of dual-frequency and single-frequency users is about 5 m and 6 m(RMS),respectively,which may be improved to about 3 m and 4 m(RMS) with the addition of differential corrections.Less accurate Signal In Space User Ranging Error(SIS URE) and Geometric Dilution of Precision(GDOP) contribute to the relatively inferior accuracy of COMPASS as compared to GPS.Since the deployment of the remaining 1 GEO and 2 MEO is not able to significantly improve GDOP,the performance gap could only be overcome either by the use of differential corrections or improvement of the SIS URE,or both.ZHOU ShanShi CAO YueLing ZHOU JianHua HU XiaoGong TANG ChengPan LIU Li GUO Rui HE Feng CHEN JunPing WU Bin 2012Science China(Physics,Mechanics & Astronomy)2012,55,12:31

15Terrestrial carbon sinks in China and around the world and their contribution to carbon neutrality显示文摘Enhancing the terrestrial ecosystem carbon sink(referred to as terrestrial C sink) is an important way to slow down the continuous increase in atmospheric carbon dioxide(CO_(2)) concentration and to achieve carbon neutrality target.To better understand the characteristics of terrestrial C sinks and their contribution to carbon neutrality,this review summarizes major progress in terrestrial C budget researches during the past decades,clarifies spatial patterns and drivers of terrestrial C sources and sinks in China and around the world,and examines the role of terrestrial C sinks in achieving carbon neutrality target.According to recent studies,the global terrestrial C sink has been increasing from a source of (-0.2±0.9) Pg C yr^(-1)(1 Pg=1015g)in the 1960s to a sink of (1.9±1.1) Pg C yr^(-1) in the 2010s.By synthesizing the published data,we estimate terrestrial C sink of 0.20–0.25 Pg C yr^(-1) in China during the past decades,and predict it to be 0.15–0.52 Pg C yr^(-1) by 2060.The terrestrial C sinks are mainly located in the mid-and high latitudes of the Northern Hemisphere,while tropical regions act as a weak C sink or source.The C balance differs much among ecosystem types:forest is the major C sink;shrubland,wetland and farmland soil act as C sinks;and whether the grassland functions as C sink or source remains unclear.Desert might be a C sink,but the magnitude and the associated mechanisms are still controversial.Elevated atmospheric CO_(2) concentration,nitrogen deposition,climate change,and land cover change are the main drivers of terrestrial C sinks,while other factors such as fires and aerosols would also affect ecosystem C balance.The driving factors of terrestrial C sink differ among regions.Elevated CO_(2) concentration and climate change are major drivers of the C sinks in North America and Europe,while afforestation and ecological restoration are additionally important forcing factors of terrestrial C sinks in China.For future studies,we recommend the necessity for intensive and long-term ecosystem C monitoring over broad geographic scale to improve terrestrial biosphere models for accurately evaluating terrestrial C budget and its dynamics under various climate change and policy scenarios.Yuanhe Yang Yue Shi Wenjuan Sun Jinfeng Chang Jianxiao Zhu Leiyi Chen Xin Wang Yanpei Guo Hongtu Zhang Lingfei Yu Shuqing Zhao Kang Xu Jiangling Zhu Haihua Shen Yuanyuan Wang Yunfeng Peng Xia Zhao Xiangping Wang Huifeng Hu Shiping Chen Mei Huang Xuefa Wen Shaopeng Wang Biao Zhu Shuli Niu Zhiyao Tang Lingli Liu Jingyun Fang 2022Science China(Life Sciences)2022,65,5:32
16Geochronology, geochemistry, and its geological significance of the Permian Mandula mafic rocks in Damaoqi, Inner Mongolia显示文摘The Hujierte-Chaganhadamiao volcanic-plutonic sequence is located in the Mandula area of northern Damaoqi, Inner Mongolia. It contains mainly mafic volcanics, with several ultramafic blocks in its central part and mafic-intermediate intrusions in the east. The zircon U-Pb ages of the gabbro and basalt samples are 278.5±3.0 Ma (MSWD=0.66) and 273.7±1.0 Ma (MSWD=0.36), respectively. These ages constrain the magmatism occurred in the Early Permian. The Mandula Permian mafic rocks are characterized by low abundances of REE and slightly LREE-enriched chondrite-normalized N-MORB-type REE patterns. And these mafic samples have high ( 143 Nd/ 144 Nd) i (0.51262-0.51270), relatively high positive ε Nd (t) (3.4-8.0), and high Mg # (49-54), suggesting derivation from the depleted asthenosphere mantle source. But they also show the enrichment in large ion lithophile elements (LILE, e.g. Rb, Ba and Sr), depletion in high field strength elements (HFSE); distinctly negative Nb, Ta anomalies and slightly negative P, Ti anomalies; high ( 87 Sr/ 86 Sr) i (0.70490-0.70537), low ( 206 Pb/ 204 Pb) i (17.39-17.93). All of these resemble the characteristics of the enriched mantle source or involvement of arc materials in the magma genesis. Furthermore, as shown in the correlation plots of ε Nd (t) vs ( 87 Sr/ 86 Sr) i , ( 206 Pb/ 204 Pb) i vs ( 207 Pb/ 204 Pb) i and ( 208 Pb/ 204 Pb) i , La/Ba La/Nb vs La/Nb, and La/Nb ratio, the magma source could have been experienced the contamination and metasomation from the previous subduction process. And the positive correlation between the selected major oxides and trace elements could be explained by the contamination from continental crust and arc materials during the magmatic emplacement. Combined with the distinct geochemistry features of Mandula mafic samples and many previous researches in the study area, the Early Permian magmatism in Mandula occurred under an extensional rift setting, and a juvenile ocean basin probably had already been formed after further development.CHEN Chen ZHANG ZhiCheng GUO ZhaoJie LI JianFeng FENG ZhiShuo TANG WenHao 2012Science China Earth Sciences2012,55,1:30

18Phosphorus Removal of High Phosphorus Iron Ore by Gas-Based Reduction and Melt Separation显示文摘A new method (gas-based separation plus melt separation) has been proposed to remove phosphorus of the high phosphorus iron ore which was 1.25% of phosphorus content and 50.0% of iron content.HSC chemistry package and the coexistence theory of slag structure were adopted for theoretical analysis.The gas-based reduction was carried out using a fixed bed reactor and the ore sample of 80 g with an average particle size of 2 mm were reduced using CO or H2 at temperature of 1073 K for 5 hours.50 g of the reduced sample with 3.0% CaO as additive was then subjected to melt separation in an electric furnace at temperature of 1873 K under Ar atmosphere.In each run,SEM,EDS,optical microscopic examination and chemical analysis of the reduced ore sample,the metal sample and the slag sample were conducted.Results of all gas-based reduction experiments showed that iron metallization ratios were some 65% and the phosphorus compounds in the ore remained unchanged.It was agreed well with the simulations except for the iron metallization rate being less than predicted value;this difference was attributed to kinetics.Results of melt separation experiments showed that P content in metal samples is 0.33% (metal sample from H2 reduction product) and 0.27 % (metal sample from CO reduction product).The phosphorus partition ratios of both cases were less than predicted values.Some P in the metal samples existed as slag inclusion was considered to be the reason for this discrepancy.TANG Hui-qing GUO Zhan-cheng ZHAO Zhi-long 2010Journal of Iron and Steel Research(International)2010,17,9:27
