Weightlessness in space induces a fluid shift from the dependent to the cephalad parts of
the body leading to distension of the cardiac chambers and an accumulation of blood in the …

Significant progress has been made in the development of countermeasures to attenuate
the negative consequences of prolonged exposure to microgravity on astronauts' bodies …

Space medicine is key to the human exploration of outer space and pushes the boundaries
of science, technology, and medicine. Because of harsh environmental conditions related to …

We investigated variations in haemodynamics in response to simulated microgravity across
a semi-subject-specific three-dimensional (3D) continuous arterial network connecting the …

Spaceflight associated neuro-ocular syndrome (SANS) alters the vision of astronauts during
long-duration spaceflights. Previously, the current authors have discussed the similarities …

Purpose Altered gravity environments introduce cardiovascular changes that may require
continuous hemodynamic monitoring in both spaceflight and terrestrial analogs. Conditions …

The present study examined if repeated bouts of micro-and hypergravity during parabolic
flight (PF) alter structural integrity of the neurovascular unit (NVU) subsequent to free radical …

This study sought to determine to what extent acute exposure to microgravity (0 G) and
related increases in central blood volume (CBV) during parabolic flight influence the …

Landing day symptoms from orthostatic hypotension after prolonged spaceflight can be
debilitating, but severity of these symptoms can be unpredictable and highly individual. We …

INTRODUCTION: Changes in gravity or body position provoke changes in hydrostatic
pressure in the arterial system and in venous return. Potential asymmetries between left …
