However, conventional imaging techniques cannot detect microvessels on micron/sub-micron scales without angiography. In this study, synchrotron radiation(SR)-based X-ray in-line phase-contrast imaging (ILPCI)and quantitative 3D characterization were used to acquire high-resolution, high-contrast images of rat brain tissue under both normal and seizure conditions. The number of blood microvessels was markedly increased on days 1 and 14, but decreased on day 60 after seizures. The surface area, diameter distribution, mean tortuosity, and number of bifurcations and network segments also showed similar trends. These pathological changes were confirmed by histological tests. Thus, SR-based ILPCI provides systematic and detailed views of cerebrovascular anatomy at the micron level without using contrast-enhancing agents. This holds considerable promise for better diagnosis and understanding of the pathogenesis and development of epilepsy.展开更多

In Study A comparing SR-test with IR-reference in a crossover design T-max and t(1/2) of propafenone for SR-test were significantly higher than those for IR-reference while C-max and AUC were lower demonstrating the sustained release properties of the new formulation. In Study B comparing SR-test with SR-reference the observed C and A TIC of propafenone for SR test (124.5 +/- 140.0 ng/mL and 612.0 +/- 699.2 ng.h/mL, respectively) were higher than for SR-reference (78.52 +/- 72.92 ng/mL and 423.6 +/- 431.6 ng.h/mL, respectively) although the differences were not significant. Overall, the new formulation has as good if not better sustained release characteristics to the market leader formulation.

These publications aroused strong response at home and abroad. Cathayornis, Confuciusornis and Liaoningornis became important reference material for study of the evolution of early birds. In the last few years, two early bird assemblages were found, i.e. the Early Cretaceous Cathayornis assemblage and the Late Jurassic Confuciusornis assemblages, which represent the biggest and richest Mesozoic bird assemblages of the world. These assemblages contain not展开更多
