| 1 | 钙钛矿结构荧光材料MZrO_3:Eu^(3+),A(M=Ca^(2+), Ba^(2+);A=Li^+, Na^+, K^+)的制备及其发光性质(英文)显示文摘Calcium and barium zirconate powders based upon CaZrO 3:Eu3+ , A and BaZrO 3:Eu3+, A(A=Li+, Na+, K+) were prepared by combustion synthesis method and heating to ~1000 °C to improve crystallinity. The structure and morphology of materials were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). XRD results showed that CaZrO 3:Eu3+, A and BaZrO 3:Eu3+, A (A=Li+, Na+, K+) perovskites possessed orthorhombic and cubic structures, respectively. The morphologies of all powders were very similar consisting of small, coagulated, cubical particles with narrow size distributions and smooth and regular surfaces. The characteristic luminescences of Eu 3 + ions in CaZrO 3 :Eu3+ , A (A=Li+, Na+, K+) lattices were present with strong emissions at 614 and 625 nm for 5D0 →7F2 transitions with other weaker emissions observed at 575, 592, 655, and 701 nm corresponding to 5D0 → 7Fn transitions (where n=0,1,3,4, respectively). In BaZrO3:Eu3 + both the 5D0 → 7F1and5D0 → 7F2 transitions at 595 and 613 nm were strong. Photoluminescence intensities of CaZrO3:Eu3+samples were higher than those of BaZrO 3:Eu3+lattices. This remarkable increase of photoluminescence intensity (corresponding to 5D0→7Fn transitions) was observed in CaZrO3:Eu3+and BaZrO3:Eu3+ if co-doped with Li + ions. An additional broad band composed of many peaks between 440 to 575 nm was observed in BaZrO3:Eu3+, A samples. The intensity of this band was greatest in Li + co-doped samples and lowest for K + doped samples. | MARíB. | 2013 | 物理化学学报2013,29,6: | 2 |

| 7 | Mesenchymal stem cells from different sources and their derived exosomes: A pre-clinical perspective显示文摘Since the introduction of cell therapy as a strategy for the treatment of many diseases,mesenchymal stem cells have emerged as ideal candidates,yet the underlying mechanisms of their beneficial effects are only partially understood.At the start of the 21st century,a paracrine effect was proposed as a mechanism of tissue repair by these cells.In addition,a role was suggested for a heterogeneous population of extracellular vesicles in cell-to-cell communication.Some of these vesicles including exosomes have been isolated from most fluids and cells,as well as from supernatants of in vitro cell cultures.Recent research in the field of regenerative medicine suggests that exosomes derived from mesenchymal stem cells could be a powerful new therapeutic tool.This review examines the therapeutic potential of these exosomes obtained from the sources most used in cell therapy:bone marrow,adipose tissue,and umbilical cord. | María álvarez-Viejo | 2020 | World Journal of Stem Cells2020,12,2: | 13 |

| 9 | PDRG1 at the interface between intermediary metabolism and oncogenesis显示文摘PDRG1 is a small oncogenic protein of 133 residues. In normal human tissues, the p53 and DNA damageregulated gene 1(PDRG1) gene exhibits maximal expression in the testis and minimal levels in the liver. Increased expression has been detected in several tumor cells and in response to genotoxic stress. High-throughput studies identified the PDRG1 protein in a variety of macromolecular complexes involved in processes that are altered in cancer cells. For example, this oncogene has been found as part of the RNA polymerase Ⅱ complex, the splicing machinery and nutrient sensing machinery, although its role in these complexes remains unclear. More recently, the PDRG1 protein was found as an interaction target for the catalytic subunits of methionine adenosyltransferases. These enzymes synthesize S-adenosylmethionine, the methyl donor for, among others, epigenetic methylations that occur on the DNA and histones. In fact, downregulation of S-adenosylmethionine synthesis is the first functional effect directly ascribed to PDRG1. The existence of global DNA hypomethylation, together with increased PDRG1 expression, in many tumor cells highlights the importance of this interaction as one of the putative underlying causes for cell transformation. Here, we will review the accumulated knowledge on this oncogene, emphasizing the numerous aspects that remain to be explored. | Maríaángeles Pajares | 2017 | World Journal of Biological Chemistry2017,8,4: | 2 |
