The Trends in Global Gene Expression in Mouse Embryonic Stem Cells During Spaceflight
The environment in space differs greatly from the environment on the ground. Spaceflight causes a number of physiological changes in astronauts, such as bone loss and immune system dysregulation.

Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.

Jumping on the moon as a potential exercise countermeasure
Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...

Introduction: Spaceflight alters normal physiology of cells and tissues seen on Earth. Immune cells and signaling molecules appear to be particularly affected, resulting in changes in leukocyte populations, killing ability and effector function, and ...

Hypogravity simulation using the Variable Gravity Suspension System: A technical report
Abstract Human movement has evolved within Earth's gravitational environment (1 g; −9.81 m s−2). Future human exploration of terrestrial bodies, including the Moon (0.17 g; −1.62 m s−2) and Mars (0.38 g; −3.71 m s−2), will require astronauts to live and work within reduced gravitational environments (hypogravity).
