Hypoxia is a state of reduced oxygen supply and excessive oxygen consumption. According
to the duration of hypoxic period, it can be classified as acute and chronic hypoxia. Both …

Hypobaric hypoxia (HH) characteristics induce impaired cognitive function, reduced
concentration, and memory. In recent years, an increasing number of people have migrated …

Many genetic and environmental factors increase susceptibility to cognitive impairment (CI),
and the gut microbiome is increasingly implicated. However, the identity of gut microbes …

Background Hypobaric hypoxia exposure leads to brain edema, followed by
