A novel open-framework vanadium(Ⅳ) phosphate (H3NCH2CH2NH3)3 [(VO)4(PO4)2(HPO4)4] (short for V2P3-en) has been pre- pared. It is synthesized hydrothermally in the presence of ethylenediamine (en) at 170℃ for 5 days by self-assembly from structurally simple precursors V2O5, H3PO4 and H2O. The compound is characterized by means of Fourier transform-infrared spectroscopy (FT-IR), Thermogravimetry-differential thermal analysis (TG-DTA), X-ray powder diffraction analysis (XRD) and Scanning electron microscopy (SEM). Furthermore, the composition-structure-thermal stability relation of V2P3-en is explored in terms of crystal chemistry, and the po- tential approach to the enhancement of its thermal stability is proposed.
·Glaucoma is one of the leading causes of visual impairment and blindness worldwide. Of known risk factors for glaucoma, an increased in intraocular pressure is most highly correlated with glaucomatous damage. Irrespective of the cause, apoptosis of the retinal ganglion cells is the eventual outcome. It is widely accepted that glaucoma is a neurodegenerative disease that is strongly correlated with central nervous system disorders, such as Alzheimer's disease. These two disorders also share some similarities in pathogenic mechanisms. Recent studies suggest that the transient receptor potential canonical 6 channel could work together with brain-derived neurotrophic factor to promote neuron survival in brain and retina. In this study, we propose that transient receptor potential canonical 6 may contribute to the pathogenesis of human glaucoma and become a potential therapeutic target.
