Molecular Mechanisms of High-Altitude Acclimatization
International Journal of Molecular Sciences, 2023 High-altitude illnesses (HAIs) result from acute exposure to high altitude/hypoxia. Numerous molecular mechanisms affect appropriate acclimatization to hypobaric and/or normobaric hypoxia and curtail the development of HAIs.

Global and country-level estimates of human population at high altitude
Proceedings of the National Academy of Sciences of the United States of America, 2021 Estimates of the global population of humans living at high altitude vary widely, and such data at the country level are unavailable. Herein, we use a geographic information system (GIS)-based approach to quantify human population at 500-m elevation ...

Impact of High Altitude on Cardiovascular Health: Current Perspectives
Vascular Health and Risk Management, 2021 Globally, about 400 million people reside at terrestrial altitudes above 1500 m, and more than 100 million lowlanders visit mountainous areas above 2500 m annually. The interactions between the low barometric pressure and partial pressure of O2, climate,
