1Humid Medieval Warm Period recorded by magnetic characteristics of sediments from Gonghai Lake, Shanxi, North China显示文摘Variations in monsoon strength, moisture or precipitation in eastern China during the MWP reflected by different climatic records have shown apparent discrepancies. Here, detailed environmental magnetic investigations and mineralogical analyses were conducted on lacustrine sediments of Core GH09B1 (2.8 m long) from Gonghai Lake, Shanxi, North China, concerning the monsoon history during the MWP. The results demonstrate that the main magnetic mineral is magnetite. The sediments with relatively high magnetic mineral concentrations were characterized by relatively fine magnetic grain sizes, which were formed in a period of relatively strong pedogenesis and high precipitation. In contrast, the sediments with low magnetic mineral concentrations reflected an opposite process. The variations of magnetic parameters in Gonghai Lake sediments were mainly controlled by the degree of pedogenesis in the lake drainage basin, which further indicated the strength of the Asian summer monsoon. The variations in the and S 300 parameters of the core clearly reveal the Asian summer monsoon history over the last 1200 years in the study area, suggesting generally abundant precipitation and a strong summer monsoon during the Medieval Warm Period (MWP, AD 910–1220), which is supported by pollen evidence. Furthermore, this 3–6-year resolution environmental magnetic record indicates a dry event around AD 980–1050, interrupting the generally humid MWP. The summer monsoon evolution over the last millennium recorded by magnetic parameters in sediments from Gonghai Lake correlates well with historical documentation (North China) and speleothem oxygen isotopes (Wanxiang Cave), as well as precipitation modeling results (extratropical East Asia), which all indicate a generally humid MWP within which centennial-scale moisture variability existed. It is thus demonstrated that environmental magnetic parameters could be used as an effective proxy for monsoon climate variations in high-resolution lacustrine sediments.LIU JianBao CHEN FaHu CHEN JianHui XIA DunSheng XU QingHai WANG ZongLi LI YueCong 2011Chinese Science Bulletin2011,56,23:28
2Pollen-inferred vegetation and environmental changes since 16.7 ka BP at Balikun Lake, Xinjiang显示文摘A high-resolution fossil pollen record from the sedimentary cores of Balikun Lake, northwestern China, combined with modern surface pollen data, is used to reconstruct the history of vegetation and climatic change since 16.7 cal. ka BP. Fossil pollen assem-blages and lithology indicate that the study area was dominated by desert. The desert had extremely arid climate and lower effec-tive moisture during 16.7–7.9 cal. ka BP, especially from 16.7 to 8.9 cal. ka BP when the lake maybe dried up. During 8.9–7.9 cal. ka BP, the environment gradually recovered in this area. It was then followed by the optimum period from 7.9 to 4.3 cal. Ka BP, when the effective moisture obviously increased. It was characterized by the typical desert-steppe/steppe vegetation and was ac-companied with several patch-birch woodlands around the lake. After that, a short but extremely arid climatic event occurred during 4.3–3.8 cal. ka BP, and the vegetation quickly changed from desert-steppe/steppe to desert. It was a relatively optimum period from 3.8 to 0.53 cal. ka BP showing typical desert-steppe/meadow-steppe landscape. Since 0.53 cal. ka BP, the climate has shown signs of deteriorating again. Furthermore, regional comparison shows that the characteristics of climatic and environmental evolution in this area were clearly different from East Asia monsoonal area during the last 16.7 cal. ka BP. It was characterized by the arid climate during the late-glacial and early Holocene, and relatively wet during the mid-late Holocene.TAO ShiChen AN ChenBang CHEN FaHu TANG LingYu WANG ZongLi LU YanBin LI ZhiFei ZHENG TongMing ZHAO JiaJu 2010Chinese Science Bulletin2010,55,22:20
3Regeneration of commercial selective catalyst reduction catalysts deactivated by Pb and other inorganic elements显示文摘The regeneration of commercial SCR(Selective Catalyst Reduction) catalysts deactivated by Pb and other elements was studied.The deactivated catalyst samples were prepared by chemical impregnation with mixed solution containing K_2SO_4,Na_2SO_4,CaSO_4,Pb(NO_3)_2and NH_4H_2PO_4.A novel method combining Ethylenediaminetetraacetic acid disodium salt(EDTA-2Na) and H_2SO_4solution(viz.catalysts treated by dilute EDTA-2Na and H_2SO_4 solution in sequence) was used to recover the activity of deactivated samples,and the effect was compared with single H_2SO_4,oxalic acid,acetic acid,EDTA or HNO_3 solutions.The surface structure,acidity and reducibility of samples were characterized by N_2adsorption–desorption,inductively coupled plasma optical emission spectrometer(ICP-OES),scanning electron microscopy(SEM),X-ray diffraction(XRD),X-ray fluorescence(XRF),H-2-temperature programmed section(H_2-TPR),NH3-temperature programmed desorption(NH3-TPD) and in situ DRIFTS.Impurities caused a decrease of specific surface area and surface reducibility,as well as Br?nsted acid sites,and therefore led to severe deactivation of the SCR catalyst.The use of an acid solution alone possibly eliminated the impurities on the deactivated catalyst to some extent,and also increased the specific surface area and Br?nsted acid sites and promoted the surface reducibility,thus recovered the activity partially.The combination of EDTA-2Na and H_2SO_4 could remove most of the impurities and improve the activity significantly.The removal of Pb should be an important factor for regeneration.Due to a high removal rate for Pb and other impurities,the combination of EDTA-2Na and H_2SO_4 solutions provided the best efficiency.Yanke Yu Jinxiu Wang Jinsheng Chen Xinjiang He Yujing Wang Kai Song Zongli Xie 2016Journal of Environmental Sciences2016,28,9:11

5Spatial distribution of supraglacial debris thickness on glaciers of the China-Pakistan Economic Corridor and surroundings显示文摘Debris-covered glaciers,characterized by the presence of supraglacial debris mantles in their ablation zones,are widespread in the China-Pakistan Economic Corridor(CPEC)and surroundings.For these glaciers,thin debris layers accelerate the melting of underlying ice compared to that of bare ice,while thick debris layers retard ice melting,called debriscover effect.Knowledge about the thickness and thermal properties of debris cover on CPEC glaciers is still unclear,making it difficult to assess the regional debris-cover effect.In this study,thermal resistance of the debris layer estimated from remotely sensed data reveals that about 54.0%of CPEC glaciers are debris-covered glaciers,on which the total debris-covered area is about 5,072 km2,accounting for 14.0%of the total glacier area of the study region.We find that marked difference in the extent and thickness of debris cover is apparent from region to region,as well as the debris-cover effect.53.3%of the total debris-covered area of the study region is concentrated in Karakoram,followed by Pamir with 30.2%of the total debris-covered area.As revealed by the thermal resistance,the debris thickness is thick in Hindu Kush on average,with the mean thermal resistance of 7.0×10^-2((m^2∙K)/W),followed by Karakoram,while the thickness in western Himalaya is thin with the mean value of 2.0×10^-2((m^2∙K)/W).Our findings provide a basis for better assessments of changes in debriscovered glaciers and their associated hydrological impacts in the CPEC and surroundings.YaJie Zheng Yong Zhang Ju Gu Xin Wang ZongLi Jiang JunFeng Wei 2020Research in Cold and Arid Regions2020,12,6:2

7Ultra-early treatment of bone marrow-derived mesenchymal stem cells for focal cerebral ischemia/ reperfusion injury显示文摘The time point at which bone marrow-derived mesenchymal stem cells (BMSCs) can be used in transplantation for the treatment of ischemic brain injury remains unclear. In the present study, BMSCs were transplanted to the ischemic site 90 minutes post-ischemia. The results demonstrated that the transplanted BMSCs improved neurological function, reduced infarct volume, increased survivin expression, decreased caspase-3 expression and reduced apoptosis. This suggests that BMSCs transplanted at an ultra-early stage ameliorated brain ischemia by increasing survivin expression, decreasing caspase-3 expression and reducing apoptosis at the ischemia/reperfusion injury site.Hongjie Fan Weidong Yu Zongli Wang Qian Wang Zhiyi He 2010Neural Regeneration Research2010,5,17:2

10An MAP kinase interacts with LHK1 and regulates nodule organogenesis in Lotus japonicus显示文摘Symbiosis receptor-like kinase(SymRK) is a key protein mediating the legume-Rhizobium symbiosis.Our previous work has identified an MAP kinase kinase,SIP2,as a SymRK-interacting protein to positively regulate nodule organogenesis in Lotus japonicus,suggesting that an MAPK cascade might be involved in Rhizobium-legume symbiosis.In this study,LjMPK6 was identified as a phosphorylation target of SIP2.Stable transgenic L.japonicus with RNAi silencing of LjMPK6 decreased the numbers of nodule primordia(NP) and nodule,while plants overexpressing LjMPK6 increased the numbers of nodule,infection threads(ITs),and NP,indicating that LjMPK6 plays a positive role in nodulation.LjMPK6 could interact with a cytokinin receptor,LHK1 both in vivo and in vitro.LjMPK6 was shown to compete with LHP1 to bind to the receiver domain(RD) of LHK1 and to downregulate the expression of two LjACS(1-aminocyclopropane-1-carboxylic acid synthase) genes and ethylene levels during nodulation.This study demonstrated an important role of LjMPK6 in regulation of nodule organogenesis and ethylene production in L.japonicus.Jun Yin Xiaomin Guan Heng Zhang Longxiang Wang Hao Li Qing Zhang Tao Chen Zeyuan Xu Zonglie Hong Yangrong Cao Zhongming Zhang 2019Science China(Life Sciences)2019,62,9:1

17Cancer-associated histone mutation H2BG53D disrupts DNA–histone octamer interaction and promotes oncogenic phenotypes显示文摘Dear Editor,Recent studies from us and others have deciphered the clinical relevance of a variety of oncohistones1 in different diseases.The H3K27M and H3K36M mutant histones exert dominant-negative effects on methylation levels of histone H3K27 and H3K36 on wildtype histone protein in pediatric brain cancers2–4 and chondroblastoma,5,6 respectively.In contrast to H3K27M and H3K36M that act in trans to cause global reduction of methylation at the respective residues,the H3G34 mutations,including H3G34V/R and H3G34W/L found in pediatric high-grade glioma and giant cell tumor of the bone,affect the H3K36 methylation in cis and alter the H3K36 methylation on the nucleosome containing the H3G34 mutation(s).Yi Ching Esther Wan Tsz Chui Sophia Leung Dongbo Ding Xulun Sun Jiaxian Liu Lina Zhu Tze Zhen Evangeline Kang Du Yang Yuchen Zhang Jitian Zhang Chengmin Qian Michael Shing Yan Huen Qing Li Maggie Zi Ying Chow Zongli Zheng Junhong Han Ajay Goel Xin Wang Toyotaka Ishibashi Kui Ming Chan 2020Signal Transduction and Targeted Therapy2020,5,1:1
