Simulated Hypergravity Activates Hemostasis in Healthy Volunteers

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Hypergravity may promote human hemostasis thereby increasing thrombotic risk. Future touristic suborbital spaceflight will expose older individuals with chronic medical conditions, who are at much higher thromboembolic risk compared with ...

Effects of gravity changes on gene expression of BDNF and serotonin receptors in the mouse brain. [PDF]

open access: yesPLoS ONE, 2017
Spaceflight entails various stressful environmental factors including microgravity. The effects of gravity changes have been studied extensively on skeletal, muscular, cardiovascular, immune and vestibular systems, but those on the nervous system are not

Stability of Medicinal Nanoemulsions to Spaceflight: Insights From the StarMed Experiment. [PDF]

open access: yesAdv Healthc Mater
Chitosan‐coated melatonin nanoemulsions (MN) recovered from a sounding rocket mission preserve droplet size and controlled‐release behavior, whereas uncoated nanoemulsions show ageing‐driven droplet growth and increased accessible drug fraction. Simple polymer coatings thus enhance the flight resilience of liquid space medicines under cumulative launch

Hypergravity down-regulates c-fos gene expression via ROCK/Rho-GTP and the PI3K signaling pathway in murine ATDC5 chondroprogenitor cells. [PDF]

open access: yesPLoS ONE, 2017
Chondrocytes are known to be physiologically loaded with diverse physical factors such as compressive stress, shear stress and hydrostatic pressure. Although the effects of those mechanical stimuli onto various cell models have been widely studied, those

An Arabidopsis PTH2 Gene Is Responsible for Gravity Resistance Supporting Plant Growth under Different Gravity Conditions

open access: yesLife, 2022
Terrestrial plants respond to and resist gravitational force. The response is termed “gravity resistance”, and centrifugal hypergravity conditions are efficient for investigating its nature and mechanism.

The effect of different gravity fields on mass transfer in the rat bone lacunar-canalicular system

open access: yesMedicine in Novel Technology and Devices, 2023
The bone lacunar-canalicular system (LCS) is an important microscopic infrastructure for signaling and solute transport in bone tissue, which guarantees normal physiological processes of the tissue, but the mass transfer laws in the LCS under different ...

Application of hypergravity in Eucalyptus and Corymbia seeds

open access: yesCiência Rural, 2018
: The aim of this study was to evaluate the growth responses of various Eucalyptus and Corymbia species subjected to different intensities of simulated hypergravity relative to the control. A centrifuge was used to simulate hypergravity. It was developed
