In contrast, the traditional Chinese Medi- cine remedy Wen Dan Tang reduces insomnia-related anxiety, which may perhaps correspond to changes in the brain-gut axis. This suggests a possible relationship between Wen Dan Tan^s pharmacological mechanism and the brain-gut axis. Based on this hypothesis, a sleep-deprived rat model was induced and Wen Dan Tang was administered using oral gavage during model es- tablishment. Wen Dan Tang significantly reduced insomnia-related anxiety and prevented Ghrelin level decreases following sleep deprivation, especially in the hypothalamus. Increased expression of Ghrelin receptor mRNA in the hypothalamus was also observed, suggesting that reduced anxi- ety may be a result of Wen Dan Tan's regulation of Ghrelin-Ghrelin receptors.展开更多

Orogenic belts, having experienced the most intensechanges of geotherm and mechanics in the lithosphere, are the important research object in thestudy of continental dynamics. For this reason, the study of orogenic belts forms a hot and dif-ficult point in the geological society and the concentration of efforts is needed for overcomingthis difficult point. China has the most orogenic belts of various types in the world, so the De-partment of Earth Sciences caught this scientific chance in the early 1990s, took the展开更多

The aim of this paper is to show that every local 2-cocycle of a von Neumann algebra R with coefficients in S (a unital dual R-bimodule) is a 2-cocycle.

Twenty-one healthy adult subjects received perceptual ability tests through these three different sensory modules at approximately 9:00, 13:00 and 18:00 in a day. The distribution of ranking for perceptual ability was significantly different among the three different time points in each individual, with highest perceptual ability in the evening compared with noon and morning, in terms of tactile sense and two-point discrimination. These findings suggest that the perceptual ability of healthy subjects fluctuates according to the time points in a day.展开更多
