Effect of high altitude on human placental amino acid transport [PDF]
Journal of Applied Physiology, 2020 Women residing at high altitudes deliver infants of lower birth weight than at sea level. Birth weight correlates with placental system A-mediated amino acid transport capacity, and severe environmental hypoxia reduces system A activity in isolated trophoblast and the mouse placenta.

Introgressive Hybridization and Hypoxia Adaptation in High-Altitude Vertebrates
Frontiers in Genetics, 2021 In natural populations of animals, a growing body of evidence suggests that introgressive hybridization may often serve as an important source of adaptive genetic variation.

Lower obesity rate during residence at high altitude among a military population with frequent migration: a quasi experimental model for investigating spatial causation. [PDF]
PLoS ONE, 2014 We sought to evaluate whether residence at high altitude is associated with the development of obesity among those at increased risk of becoming obese. Obesity, a leading global health priority, is often refractory to care.

Transcriptional landscape in rat intestines under hypobaric hypoxia [PDF]
PeerJ, 2021 Oxygen metabolism is closely related to the intestinal homeostasis environment, and the occurrence of many intestinal diseases is as a result of the destruction of oxygen gradients.

Extensive study of radiation dose on human body at aviation altitude through Monte Carlo simulation [PDF]
Life Sciences in Space Research, 31, (2021), 1-13, 2021 The diverse near-Earth radiation environment due to cosmic rays and solar radiation has direct impact on human civilization. In the present and upcoming era of increasing air transfer, it is important to have precise idea of radiation dose effects on human body during air travel.
