During spaceflight, fluids shift headward, causing internal jugular vein (IJV) distension and
altered hemodynamics, including stasis and retrograde flow, that may increase the risk of …

Lower body negative pressure (LBNP) has been proposed as a countermeasure to mitigate
the cephalad fluid shift occurring during spaceflight, which may be associated with the …

Head-down tilt (HDT) has been widely proposed as a terrestrial analog of microgravity and
used also to investigate the occurrence of spaceflight-associated neuro-ocular syndrome …

The ability to coordinate actions between the limbs is important for many operationally
relevant tasks associated with space exploration. A future milestone in space exploration is …

Purpose: The purpose of this study was to determine posture-induced changes in arterial
blood pressure (ABP), intraocular pressure (IOP), orbital pressure (Porb), intracranial …

Objectives: 3D imaging provides accurate records for treatment planning, diagnosis, and
monitoring treatment over time. Being able to take 3D images while patients have …

Extended exposure to microgravity has detrimental effects on human health. Long-duration
missions to the Moon, Mars, and beyond will contend with partial gravity on planetary …

Abstract The β1, 2-adrenergic receptor blocker propranolol, β1-blocker bisoprolol, and
central presynaptic α2-adrenergic receptor agonist methyldopa are used in clinical practice …

L'exposition à la microgravité entraine des changements multi-systémiques chez l'être
humain, pouvant être délétères sur le long terme ou lors d'un retour rapide à une gravité …

Under the influence of standard developmental physiology on the Earth's surface (1 gravity
equivalent known as “1G”), 70% of body fluids reside below the level of the heart. Fluid shifts …
