| 2 | Synthesis of mesoporous core-shell structured GdPO:Eu@SiO@mSiO nanorods for drug delivery and cell imaging applications显示文摘Mesoporous GdPO4:Eu@SiO2@mSiO2 core-shell nanorods(NRs) were prepared by a facile two-step method.First,the monodispersed GdPO4:Eu NRs were obtained on a large scale via a facile precipitation method,then mesoporous silica was wrapped onto their surface through hydrolysis of tetraethylorthosilicate(TEOS).The XRD result indicates that the as-prepared GdPO4:Eu NRs core has hexagonal phase.The FTIR and the N2 adsorption/desorption isotherm analysis confirm the successful coating of mesoporous silica.The TEM images show that the obtained GdPO4:Eu@SiO2@mSiO2 NRs exhibit uniform monodisperse core-shell structure with a nanorod core(length of 200 nm;width of 20 nm),and mesoporous silica shell of 15 nm.Under excitation of 274 nm,GdPO4:Eu@SiO2@mSiO2 NRs show strong red luminescence from 5 D0→7 FJ(J=1,2,3 and 4) transitions of Eu3+.Furthermore,the GdPO4:Eu@-SiO2@mSiO2 NRs exhibit obvious T1 enhancement effect due to paramagnetism of Gd3+.The drug loading capacity and pH-sensitive releasing behavior of the as-prepared GdPO4:Eu@SiO2@mSiO2 NRs were studied by using doxorubicin(DOX) as model drug.The excellent biocompatibility of GdPO4:Eu@-SiO2@mSiO2 NRs was demonstrated by MTT assay.Taken together,the mesoporous GdPO4:Eu@-SiO2@mSiO2 NRs may be potentially applied in fields of drug delivery and dual-modal imaging. | Yanli Wu Xianzhu Xu Xiuli You Qiang Xiao | 2020 | Journal of Rare Earths2020，38，10： | 1 |
| 3 | Extensive sequence divergence between the reference genomes of Taraxacum kok-saghyz and Taraxacum mongolicum显示文摘Plants belonging to the genus Taraxacum are widespread all over the world,which contain rubber-producing and non-rubberproducing species.However,the genomic basis underlying natural rubber(NR)biosynthesis still needs more investigation.Here,we presented high-quality genome assemblies of rubber-producing T.kok-saghyz TK1151 and non-rubber-producing T.mongolicum TM5.Comparative analyses uncovered a large number of genetic variations,including inversions,translocations,presence/absence variations,as well as considerable protein divergences between the two species.Two gene duplication events were found in these two Taraxacum species,including one common ancestral whole-genome triplication and one subsequent round of gene amplification.In genomes of both TK1151 and TM5,we identified the genes encoding for each step in the NR biosynthesis pathway and found that the SRPP and CPT gene families have experienced a more obvious expansion in TK1151 compared to TM5.This study will have large-ranging implications for the mechanism of NR biosynthesis and genetic improvement of NR-producing crops. | Tao Lin Xia Xu Huilong Du Xiuli Fan Qingwen Chen Chunyan Hai Zijian Zhou Xiao Su Liquan Kou Qiang Gao Lingwei Deng Jinsheng Jiang Hanli You Yihua Ma Zhukuan Cheng Guodong Wang Chengzhi Liang Guomin Zhang Hong Yu Jiayang Li | 2022 | Science China(Life Sciences)2022，65，3： | 0 |
