PURPOSE To prepare amniotic extraction (AE) and to test its antiangiogenic effect in vivo and in vitro. METHODS AE was prepared and diluted to 50, 100, and 200 microg/mL concentrations. Alkali burn-induced corneal neovascularization (NV) was produced and topically treated with different concentrations of AE or 0.1% dexamethasone for 7 days. Normal saline(More)
PURPOSE Plasminogen kringle 5 (K5) is a potent angiogenic inhibitor. The purpose of the present study was to evaluate the therapeutic effect of K5 on alkali-burn-induced corneal neovascularization (NV) and to investigate its mechanism of action. METHODS Corneal NV was induced in rabbits by NaOH. The rabbits received eye drops containing K5 or vehicle(More)
Understanding how landscape components affect the urban heat islands is crucial for urban ecological planning and sustainable development. The purpose of this study was to quantify the spatial pattern of land surface temperatures (LSTs) and associated heat fluxes in relation to land-cover types in Beijing, China, using portable infrared thermometers,(More)
The Mid-eastern Inner Mongolia of China, a typical agro-pastoral transitional zone, has undergone rapid agricultural land use changes including land reclamation and cropland abandonment in past decades due to growing population and food demand, climatic variability, and land use policy such as the "Grain for Green" Project (GFG Project). It is significant(More)
Analysis of urban distribution and its expansion using remote sensing data has received increasing attention in the past three decades, but little research has examined spatial patterns of urban distribution and expansion with buffer zones in different directions. This research selected Hangzhou metropolis as a case study to analyze spatial patterns and(More)
Since implementation of reform and opening-up policy in China in 1970s, some meteorological observation stations 'entered' into cities passively due to urban expansion. Along with the development of economic and society, spatial expansion of urban land becomes to be the major character of land-use change now and in the future in China gradually (Liu et al.(More)
A holistic understanding of the magnitude and long-term trend of water vulnerability is essential for making management decisions in a given river basin. Existing procedures to assess the spatiotemporal dynamic of water vulnerability in complex mega-scale river basins are inadequate; a new method named ensemble hydrologic assessment was proposed in this(More)
