Exercises and skin physiology during International Space Station expeditions.
Aerosp Med Hum Perform. 2021 Mar 1;92(3):160-6.
Note: ISS results. From the abstract: “The first skin physiological pilot experiment (SkinA) on a single astronaut showed a deterioration of the skin. In a follow-up experiment (SkinB) we showed that skin physiological parameters improved on average. However, it is well known that sports have positive effects on the skin, that astronauts prefer special sports devices, and do sports with different intensity. The aim of this study was to analyze the different sports activities of SkinB astronauts and to find out whether they have an influence on the skin physiological parameters.”

Aging-like metabolic and adrenal changes in microgravity: State of the art in preperation for Mars.

Note: From the abstract: “Support for the role of gravity in aging has mostly come from ground simulation studies in head down bed rest. However, uncertainties remain and have to be resolved in planning for the ambitious enterprise of sending humans to Mars and back. Stress-related corticosteroid changes and metabolic adaptation to microgravity and their relationship with aging are the object of the present review mostly, albeit of course non exclusively, coming from the personal experience of the authors.” J. Vernikos was affiliated with NASA Headquarters.

Hyperoxic effects on decompression strain during alternating high and moderate altitude exposures.
Aerosp Med Hum Perform. 2021 Apr 1;92(4):223-30.
Note: From the abstract: “In fighter aircraft, long-duration high-altitude sorties are typically interrupted by refueling excursions to lower altitude. In normoxia, excursions to moderate cabin altitude may increase the occurrence of venous gas emboli (VGE) at high cabin altitude. The aim was to investigate the effect of hyperoxia on VGE and decompression sickness (DCS) during alternating high and moderate altitude exposure.”
