Cerebral hemodynamic characteristics of acute mountain sickness upon acute high-altitude exposure at 3,700 m in young Chinese men. [PDF]
, 2014 PURPOSE: We aimed at identifying the cerebral hemodynamic characteristics of acute mountain sickness (AMS). METHODS: Transcranial Doppler (TCD) sonography examinations were performed between 18 and 24 h after arrival at 3,700 m via plane from 500 m (n ...

Human adaptation to high altitude: a review of convergence between genomic and proteomic signatures
Human Genomics, 2022 Both genomics- and proteomics-based investigations have identified several essential genes, proteins, and pathways that may facilitate human adaptive genotype/phenotype in a population-specific manner.

Internal sensations as a source of fear: exploring a link between hypoxia and flight phobia [PDF]
, 2013 Although flight phobia is very common in the general population, knowledge of the underlying mechanisms is limited. The aim of the current study is to determine whether hypoxia is selectively associated with flight anxiety. We wanted to explore levels of

Developmental responses to high altitude hypoxia [PDF]
American Journal of Physical Anthropology, 1970 AbstractFrom a review of published literature on developmental responses to high altitude, three major conclusions are derived. First, the small birth weight of high altitude native populations are adaptive responses to reduce the oxygen requirements, while the relative increase in the placental weight is a compromise mechanism to increase the volume ...

Developmental adaptation to high altitude hypoxia [PDF]
International Journal of Biometeorology, 1977 Experimental studies on animals and humans exposed to hypoxic stress have been reviewed. These data suggest that the influence of hypoxic stress, and the organism's response to it, are greater during growth than during adulthood. The organism's responses include alterations in the quantity and size of the alveolar units of the lungs, enlargement of the

Humans at high altitude: Hypoxia and fetal growth [PDF]
Respiratory Physiology & Neurobiology, 2011 High-altitude studies offer insight into the evolutionary processes and physiological mechanisms affecting the early phases of the human lifespan. Chronic hypoxia slows fetal growth and reduces the pregnancy-associated rise in uterine artery (UA) blood flow. Multigenerational vs.

Physiological Genomics of Adaptation to High-Altitude Hypoxia
Annual Review of Animal Biosciences, 2021 Population genomic studies of humans and other animals at high altitude have generated many hypotheses about the genes and pathways that may have contributed to hypoxia adaptation. Future advances require experimental tests of such hypotheses to identify causal mechanisms.

Regulation of CYP450 and drug transporter mediated by gut microbiota under high-altitude hypoxia
Frontiers in Pharmacology, 2022 Hypoxia, an essential feature of high-altitude environments, has a significant effect on drug metabolism. The hypoxia–gut microbiota–CYP450/drug transporter axis is emerging as a vital factor in drug metabolism.
