Over 140 million people live at high altitude, defined as living at an altitude of 2400 m or more above sea level. Subjects living under these conditions are continuously living under hypoxic conditions and, depending on ...

Background: Decreased hemoglobin is a manifestation of chronic kidney disease (CKD), and people who reside at high altitude adapt to hypoxia by increasing their hemoglobin. The study's objective was to determine the ...

Early acclimatization to high altitude is characterized by various respiratory, hematological, and cardiovascular adaptations that serve to restore oxygen delivery to tissue. However, less is understood about renal function ...

In the 1930–1940s Levy and coworkers administered low oxygen tension (thus simulating exposure to an altitude of about 5000 m) while monitoring ECG, in order to demonstrate coronary inadequacy resulting from imbalance ...

ABSTRACT Background Altitude exposure causes acute sleep disruption in non-athletes, but little is known about its effects in elite athletes. The aim of this study was to examine the effects of altitude on two groups ...

Residents at high altitude cope with decreasing inspiratory oxygen partial pressure by stimulating erythropoiesis. The increase in hemoglobin levels requires high amounts of additional iron supplied from the diet. Here, ...

Background : High altitude is associated with hypobaric hypoxia and increased risk for microalbuminuria in adults. We hypothesized that healthy adolescents at higher altitude might have an increased frequency of microalbuminuria ...

It is thought that adaptive changes protect high-altitude populations against altitude-induced diseases, but information from well controlled studies is lacking. In a prospective, controlled study, we assessed the prevalence ...
