High-altitude cerebral edema (HACE) is considered an end-stage acute mountain sickness (AMS) that typically occurs in people after rapid ascent to 2500 m or more. While hypoxia is a fundamental feature of the pathophysiological mechanism of HACE, em
2015). Although the biogeographical avian history of the western part of Tibetan Plateau has little information, research on the Snow Leopard (Panthera uncial) showed a clear biogeographical pattern in the distribution of three subspecies with Northern (the Altai region), Central (core Himalaya and...
Therefore, the airplane is said to be operating at a low density-altitude (see Figure 17-4). The performance of the airplane at the altitude is improved over that of a standard day. The opposite holds true for a hot day (high-density altitude). (2) Density Corrections Based on ...
The impact of clearing and conversion of dry Afromontane forests into arable land on the composition and density of soil seed banks The soil seed bank was sampled in forest, recent gaps and arable land at a site within the dry Afromontane forest belt in eastern Ethiopia. The regeneratio.....
High-altitude adaptation of Tibetans represents a remarkable case of natural selection during recent human evolution. Previous genome-wide scans found many non-coding variants under selection, suggesting a pressing need to understand the functional role
