Abstract The hypoxic environment on mountain plateaus exerts a significant negative impact on human cognitive ability and physiological well-being. Although progress has been made in the study of the cognitive decline of sojourners exposed to hypoxic environments, further knowledge that establishes the proper indoor oxygen environment beneficial for ...

Effect of Flying at High Altitude on Early Exposure of Paracetamol in Humans
Drug Research, 2018AbstractPharmacokinetics of paracetamol (APAP) was studied on-board during an air flight and compared to those on ground after 500 mg oral dose in 20 healthy human volunteer in parallel design study. Saliva samples were obtained every 15 min up to 2 h after dosing.

Effect of high altitude on the visual evoked responses in humans on Mt. Everest
Neurosurgery, 1987Cerebral visual evoked potentials (VEPs) were collected over a 1-year period from the summer of 1983 through the summer of 1984 from 16 members of the American Ultima Thule Everest Expedition at sea level and at altitudes of 7,100 ft, 16,800 ft, and 21,300 ft.

Effects of persistent organic pollutants on environment, health and mountains: a review
Journal of Environmental Engineering and Science, 2023Persistent organic pollutants (POPs) are chemicals that persists in environment, bio-accumulate through the food chain and can exhibit toxic effects with threatening effects to environment, humans and animals. Due to their volatility and semi-volatility,

Effect of high altitude (14,100 Ft.) on nitrogenous components of human serum
Metabolism, 1968Abstract Serum free amino acids and nitrogenous metabolites were measured in 8 male subjects exposed to a high altitude of 14,100 feet for 14 days. The ratio of total essential amino acids to total nonessential amino acids was decreased at altitude. Glutamic acid increased and leucine, lysine, valine and threonine decreased significantly at altitude.

Effects on regional brain metabolism of high-altitude hypoxia: a study of six US marines.
American Journal of Physiology. Regulatory Integrative and Comparative Physiology, 1999Previous studies of brain glucose metabolism in people indigenous to high-altitude environments uncovered two response patterns: Quechuas native to the high Andes of South America sustained modest hypometabolism in most brain regions interrogated ...

The effect of high altitude on the protein composition of human blood
Bulletin of Experimental Biology and Medicine, 1961Twelve healthy young individuals had the protein composition of their blood determined in Stalinabad (850 m) and during their sojourn in the mountain of East Pamir between the months of May and October, 1958, at the altitude of 4200 m.

Effect of 2 Hours' Exposure to Simulated High Altitude (4,500 m) on Human Red Cell Metabolism
Scandinavian Journal of Clinical and Laboratory Investigation, 1972During acute exposure to high altitude (2 hours) the red cell metabolism is altered. A pH-induced increase in phosphofructokinase activity together with a decrease in the level of the monophosphoglycerates are the most prominent features of the changes. Despite the increase in pH, the level of 2,3-diphos-phoglycerate is not altered, probably because of

Scandinavian Journal of Clinical and Laboratory Investigation, 1972
The effect of exposure to simulated high altitude (4,500 m) on the concentration of 2,3-diphosphoglycerate (2,3-DPG) and adenosine triphosphate (ATP) in the red cell and the oxygen affinity of hemoglobin (P50) (measured at PCO2=40 mm Hg and corrected to plasma pH=7.40) was studied.
