Biomedical response of femurs in male Wistar rat in chronic hypergravity environments
Medicine in Novel Technology and Devices, 2022 Bone is sensitive to mechanical stimulation and plays a loading-bearing role in the human body. However, regulation of bone biomechanical properties in chronic hypergravity environments is still unclear. In this study, male Wistar rats exposed to chronic

Hypergravity enhances the therapeutic effect of dexamethasone in allergic asthma and rhinitis animal model. [PDF]
PLoS ONE, 2018 We investigated whether the therapeutic effects of dexamethasone for allergic asthma and rhinitis were enhanced in mice when exposed to hypergravity. Forty mice were divided into 5 groups (n = 8/group): Control group received saline intraperitoneally (i ...

Human cardiovascular adaptation to hypergravity
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2022 Despite decades of experience from high-gravitoinertial (G) exposures in aircraft and centrifuges, information is scarce regarding primary cardiovascular adaptations to +Gz loads in relaxed humans. Thus, effects of G-training are typically evaluated after regimens that are confounded by concomitant use of anti-G straining maneuvers, anti-G suits, and ...

Simulated Hypergravity Activates Hemostasis in Healthy Volunteers
Journal 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 ...

Planarians Sense Simulated Microgravity and Hypergravity [PDF]
BioMed Research International, 2014 Planarians are flatworms, which belong to the phylumPlatyhelminthes.They have been a classical subject of study due to their amazing regenerative ability, which relies on the existence of adult totipotent stem cells. Nowadays they are an emerging model system in the field of developmental, regenerative, and stem cell biology.

Measuring Intracellular Viscosity in Conditions of Hypergravity [PDF]
Biophysical Journal, 2019 Gravity-sensitive cellular responses are regularly observed in both specialized and nonspecialized cells. One potential mechanism for this sensitivity is a changing viscosity of the intracellular organelles. Here, we report a novel, to our knowledge, viscosity-sensitive molecular rotor based on mesosubstituted boron-dipyrrin used to investigate the ...

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