DNA DOUBLE STRAND REPAIR DURING HEAD-DOWN-TILT BEDREST: AGBRESA MEETS RADIATION [PDF]

, 2020
BACKGROUND Radiation and reduced gravity impose a major burden on health and performance during human spaceflight. While radiation increases cancer risk and limits tissue regeneration, reduced gravity predisposes to musculoskeletal and cardiovascular ...

Operational and Human Factors Implications of Physiological Deconditioning in Long Duration Spaceflight

, 1992
A major factor in determining the success of any manned long duration space mission will be how well the human body can endure the microgravity environment.

Increasing seated reaction forces with lower body negative pressure

npj Microgravity
This study evaluates reaction forces and cardiovascular responses during seated lower body negative pressure (LBNP). Ten healthy subjects were exposed to randomized LBNP levels (−10 to −40 mmHg) while seated in a sealed chamber.

Regulation of muscle sympathetic nerve activity after bed rest deconditioning

, 2001
Cardiovascular deconditioning reduces orthostatic tolerance. To determine whether changes in autonomic function might produce this effect, we developed stimulus-response curves relating limb vascular resistance, muscle sympathetic nerve activity (MSNA),

Gut matters in microgravity: potential link of gut microbiota and its metabolites to cardiovascular and musculoskeletal well-being

Nutrition & Metabolism
The gut microbiota and its secreted metabolites play a significant role in cardiovascular and musculoskeletal health and diseases. The dysregulation of the intestinal microbiota poses a significant threat to cardiovascular and skeletal muscle well-being.

Infection to hypertension: a review of post-COVID-19 new-onset hypertension prevalence and potential underlying mechanisms

Frontiers in Cardiovascular Medicine
Post-COVID new-onset hypertension (PCNH) is an increasingly reported complication among COVID-19 survivors. PCNH can emerge up to 12 months postinfection, with elevated risks observed among older patients, particularly those who experienced severe COVID ...

Implications of sex differences in orthostatic tolerance during exposure to acute artificial gravity

npj Microgravity
Development of countermeasures to minimise spaceflight deconditioning is of paramount importance, such as the short-arm human centrifuge (SAHC); however, sex differences in cardiovascular responses should be considered. 20 participants (female = 10, male
