Physiological benefits of Akkermansia muciniphila under high-altitude hypoxia
Applied Microbiology and Biotechnology, 2022When sojourners visit to high altitude, various symptoms may appear in the body including gastrointestinal symptoms such as poor appetite or nausea, vomiting, and incapacitating. The gastrointestinal tract is a key organ involved in the development of acute mountain sickness (AMS). The intestinal epithelial lining is covered by mucus layer.

Pregnancy alters cerebrovascular adaptation to high-altitude hypoxia
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1994We have previously shown alterations in cerebrovascular composition, contractility, and endothelial function in normoxic pregnant (P) and chronically hypoxic nonpregnant (HNP) adult sheep compared with nonpregnant normoxic controls (NP). This study focuses on a fourth group, pregnant sheep exposed to chronic high-altitude hypoxia (HP) (110 days at 3 ...

Criteria for Psychological Adaptation to High-Altitude Hypoxia
Perceptual and Motor Skills, 1999The purpose of this study was to test an ascent program for ideal psychological adaptation to high altitudes. A psychological approach was used to test a model describing a gradual step-by-step ascent. Seven subjects spent nine days between 3,500 m and 4,400 m altitude, followed by eight days climbing 500 m each day from 3,500 m to 5,400 m.

Human red cell glycolysis in high altitude chronic hypoxia
American Journal of Physical Anthropology, 1984AbstractWe have found that glycolysis in human red blood cells under the hypoxic conditions found at high altitudes is connected with changes in enzyme activities and levels of various metabolic intermediates.The sensitivity of the four kinases to hypoxia results in 1) glycolytic hyperactivity leading to a higher intracellular energy state, and 2 ...
