1Opening of an early Paleozoic limited oceanic basin in the northern Altyn area: Constraints from plagiogranites in the Hongliugou-Lapeiquan ophiolitic mélange显示文摘This paper reports petrological and geochemical features and zircon U-Pb age of plagiogranite from the Hongliugou-Lapeiquan ophiolitic mélange belt in the northern Altyn Tagh. The zircon U-Pb dating results yield a mean 238U/206Pb age of 512.1 - 1.5 Ma, representing an emplacement time of the plagiogranites in the Middle Cambrian. The plagiogranites are interpreted to have derived from anatexis of hydrated amphibolites by ductile shearing during transports of the oceanic crust. Thus it is believed that the formation age of such type of plagiogranite was coeval to or slightly younger than the spreading of the Hongliugou-Lapeiquan limited oceanic basin. The new results from the plagiogranites suggest that an oceanic basin existed in the northern Altyn area during the Middle Cambrian.GAO XiaoFeng XIAO PeiXi GUO Lei DONG ZengChan XI RenGang 2011Science China Earth Sciences2011,54,12:18
2Progress in the participation of Ca^(2+)-calmodulin in heat shock signal transduction显示文摘A novel heat shock(HS) signal transduction pathway in plants for the participation of Ca2+-calmodulin(CaM) in HS signal trans-duction was identified.HS induces a rapid increase in intracellular free calcium ion levels([Ca2+]i),and the involvement of phospholipase Cinositol 1,4,5-trisphosphate is one of the factors leading to elevation in [Ca2+]i induced by HS.HS also increases the expression of the CaM gene and the accumulation of the CaM protein.The CaM isoform,AtCaM3,in Arabidopsis is a key member in the HS signal trans-duction pathway.AtCaM3 regulates the activity of CaM-binding protein kinase(AtCBK3) or protein phosphatase(AtPP7),promoting the activation of the HS transcription factor,AtHSFA1a,by phosphorylation/dephosphorylation and the expression of heat shock pro-tein genes,then improving heat tolerance in plants.Rengang Zhou Bing Li Hongtao Liu Daye Sun 2009Progress in Natural Science:Materials International2009,19,10:10
3Comparison of the differentiation of dental pulp stem cells and periodontal ligament stem cells into neuron-like cells and their effects on focal cerebral ischemia显示文摘Recent studies have reported an in creasing in cidence of ischemic stroke,particularly in younger age groups.Dental pulp stem cells(DPSCs)and periodontal ligament stem cells(PDLSCs)are the most comm on stem cells acquired from the teeth of adults,even elderly people.However,there are no detailed reports on whether DPSCs or PDLSCs are suitable for the treatment of ischemic stroke.In this study,the in vitro differentiation of DPSCs and PDLSCs into neuron-like cells was evaluated.Then,we established a rat model of cerebral ischemia.DPSCs or PDLSCs were administered to animals,and the therapeutic effects of these two types of cells were investigated.The results showed that PDLSCs had a higher differentiation rate than DPSCs.Immunofluorescence studies showed that the expression of the neuronal differentiation markerThy-1 was higher in PDLSCs than in DPSCs,and other gene markers of neuronal differentiation showed corresponding trends,which were confirmed by western blot analysis.In this process,the Notch and Wnt signaling pathways were inhibited and activated,respectively.Fin ally,rats with transient occlusion of the right middle cerebral artery were used as a model to assess the therapeutic effect of PDLSCs and DPSCs on ischemia.The results showed that rats in the PDLSC-treated group emitted significantly greater red fluorescence signal than the DPSC-treated group.PDLSC transplantation promoted the recovery of neurological function more effectively than DPSC transplantation.Hence,PDLSCs represent an autogenous source of adult mesenchymal stem cells with desirable biological properties and may be an ideal candidate for clinical applications.Tingting Wu Wanting Xu Hanlin Chen Shasha Li Rengang Dou Hongtao Shen Xue Liu Xiaoyu Liu Yongfeng Hong Jiacai He 2020Acta Biochimica et Biophysica Sinica2020,52,9:2
