High-altitude illnesses: Old stories and new insights into the pathophysiology, treatment and prevention

Sports Medicine and Health Science, 2021
Areas at high-altitude, annually attract millions of tourists, skiers, trekkers, and climbers. If not adequately prepared and not considering certain ascent rules, a considerable proportion of those people will suffer from acute mountain sickness (AMS ...

The Use of Pulse Oximetry in the Assessment of Acclimatization to High Altitude

Italian National Conference on Sensors, 2021
Background: Finger pulse oximeters are widely used to monitor physiological responses to high-altitude exposure, the progress of acclimatization, and/or the potential development of high-altitude related diseases.

Hypoxia and Inflammation: Insights From High-Altitude Physiology

Frontiers in Physiology, 2021
The key regulators of the transcriptional response to hypoxia and inflammation (hypoxia inducible factor, HIF, and nuclear factor-kappa B, NF-κB, respectively) are evolutionarily conserved and share significant crosstalk. Tissues often experience hypoxia

Does the pathogenesis of SARS-CoV-2 virus decrease at high-altitude?

Respiratory Physiology & Neurobiology, 2020
Highlights • COVID-19 infection is decreased in populations living at an altitude of above 3000 masl.• Highland inhabitants may be less susceptible to SARS-CoV-2 virus infection due to physiological acclimatization to hypoxia.• High-altitude ...

Targeting JUN, CEBPB, and HDAC3: A Novel Strategy to Overcome Drug Resistance in Hypoxic Glioblastoma

Frontiers in Oncology, 2019
Hypoxia is a predominant feature in glioblastoma (GBM) and contributes greatly to its drug resistance. However, the molecular mechanisms which are responsible for the development of the resistant phenotype of GBM under hypoxic conditions remain unclear ...

Origin and adaptation to high altitude of Tibetan semi-wild wheat

Nature Communications, 2020
Tibetan wheat is grown under environmental constraints at high-altitude conditions, but its underlying adaptation mechanism remains unknown. Here, we present a draft genome sequence of a Tibetan semi-wild wheat (Triticum aestivum ssp.

High altitude reduces infection rate of COVID-19 but not case-fatality rate

Respiratory Physiology & Neurobiology, 2020
Highlights • High altitude reduces infection rate of COVID-19.• High altitude does not change case-fatality rate due to COVID-19.• Female protection towards death by COVID-19 is reduced as altitude of residence increases.
