Control and modulation of atmospheres can be utilized to understand the physical composition and behavior of materials or to investigate key evolutionary, ecological, physiological and biomedical questions.
A subset of applications includes Anoxic or hypoxic pre/ post-natal development, CO2 control in incubation, post- harvest storage, aerobic capacity of athletic performance, circadian rhythm and sleep studies, and adaptation to hypoxia in burrowing organisms. Cellular mechanisms are better understood from model animal investigations of the effect of O2 concentrations on reperfusion injury from stroke or trauma, reactive oxygen species regulation and the oxidative stress response.
