Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, EarlyView.
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 ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Influence of menstrual cycle phase on inflammatory and vascular responses to acute passive heating in healthy young women

Experimental Physiology, EarlyView.
Abstract The aim of this study was to determine whether inflammatory and vascular responses to passive heating differ between the early follicular phase (EFP) and the mid‐luteal phase (MLP) of the menstrual cycle. Ten healthy, naturally menstruating females (26 ± 3 years of age; body mass index 21.4 ± 1.9 kg/m2) were assessed during EFP and MLP ...

Time‐course analysis of cerebral circulation and cardiorespiratory responses to acute central blood volume reduction in healthy young males

Experimental Physiology, EarlyView.
Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

A computational model for retinal haemodynamics under gravitational and postural variations

The Journal of Physiology, EarlyView.
Abstract figure legend The haemodynamic impact of gravitational and postural changes on the retina, and its relevance to spaceflight associated neuro‐ocular syndrome (SANS), remains incompletely characterized. This study assesses retinal haemodynamics from upright to head‐down tilt using a lumped‐parameter model that dynamically couples intraocular ...
