BackgroundHigh-altitude populations exhibit distinct cellular, respiratory, and cardiovascular phenotypes, some of which provide adaptive advantages to hypoxic conditions compared to populations with sea-level ancestry. Studies performed in populatio

Histomonosis is a disease of poultry caused by Histomonas meleagridis. Chickens usually recover while the mortality rate in turkeys is high. The immunological response of both species towards H. meleagridis was investigated. Parasites migrated in gre

Many vertebrate animals have superior tolerance to environmental hypoxia compared to humans. For example, turtles tolerate an environment of 100% N2 for several hours, without apparent ill effect. This hypoxia tolerance is not limited to heterotherms

Chronic hypoxia increases the hypoxic ventilatory response (HVR) in awake rats and the phrenic nerve response to carotid sinus nerve stimulation in anesthetized rats. An increased O2 sensitivity of the arterial chemoreceptors contributes to the incre

During exercise, pulmonary gas exchange in reptiles was predicted to differ from that in mammals because of their less complex lung structure, which might reduce ventilation–perfusion heterogeneity at the expense of pulmonary diffusion limitation.

To test the hypothesis that the hypoxic ventilatory response (HVR) of an individual is a constant unaffected by acclimatization, isocapnic 5-min step HVR, as delta VI/delta SaO2 (l.min-1.%-1, where VI is inspired ventilation and SaO2 is arterial O2 s
