Osteosarcoma is the most common type of solid bone cancer, which is the second leading cause of cancer-related death. Hypoxia is an ordinary phenomenon in solid tumor tissues and can induce cell apoptosis but the specific molecular mechanism remains unclear. In this study, we explored the effect and the molecular mechanism of Transglutaminase 2 (TG2) on(More)
A novel red-emitting phosphor SrO . Y2O3 : Eu was synthesized by glycine combustion process. The phases and structure, the size and morphology, and the luminescent properties of the samples were investigated respectively by XRD, SEM and fluorescence spectrophotometer (FL). The results show that the samples include two phases, SrY2O4 and Y2O3, which belong(More)
In the present paper,with CoCl2 x 6H2O used as precursor, Co-doped ZnO diluted magnetic semiconductor (DMS) crystals were synthesized by hydrothermal method with KOH as mineralizer. The morphology, and the relative content and distribution uniformity of the surface and inner Co element of synthesized crystals were investigated by scanning electron(More)
Gd2O2S: Eu, Mg, Ti, a novel red long afterglow phosphor, was synthesized in microwave field. The synthesized phosphors were investigated respectively by XRD, SEM and fluorescence spectrophotometer. The results show that Gd2O2S: Eu, Mg, Ti phosphors possess hexagonal crystal structure, which is similar to that of Gd2O2S. The particles of Gd2O2S: Eu, Mg, Ti(More)
Inspirable nano-particles into lungs in the atmosphere were studied in this paper. Field emission scanning electron microscope (FSEM) and X-ray energy dispersive spectrometer were used to investigate the morphology and major constituents of inspirable nano-particles into lungs systematically. The results showed that most of the inspirable nano-particles in(More)
Gd2O3: Eu nanocrystal was synthesized by EDTA complexing sol-gel process at relatively low temperature, in which ethylene-diamine-tetraacetic acid (EDTA) and polyethylene glycol (PEG) were used as the chelating agent and disperser respectively. The properties of the nanocrystal were investigated by XRD, SEM, EDS, and fluorescence spectrophotometer. The(More)
