Hypergravity Attenuates Reactivity in Primary Murine Astrocytes [PDF]

Biomedicines, 2022
Neuronal activity is the key modulator of nearly every aspect of behavior, affecting cognition, learning, and memory as well as motion. Hence, disturbances of the transmission of synaptic signals are the main cause of many neurological disorders. Lesions

Insect exoskeletons react to hypergravity [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2023
A typical feature of biological materials is their ability to adapt to mechanical load. However, it is not known whether the cuticle exoskeleton, one of the most common biological structures, also shares this trait. Here, we show direct experimental evidence that prolonged exposure to hypergravity conditions affects the morphology and biomechanics of ...

Simulated Hypergravity Activates Hemostasis in Healthy Volunteers [PDF]

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 ...

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 ...

Hypergravity Conditioning on Ileal Movements in Rats [PDF]

Aviation, Space, and Environmental Medicine, 2012
Stress is a common trigger for various physiological disturbances, including feeding disorders. One of the possible mechanisms for feeding disorders may be linked to changes in intestinal movement caused by stress. Therefore, here we investigated in vitro stress-induced changes in ileal movement.Rats (female Wistar, SPF) were divided into Control (1 G)

Application of hypergravity in Eucalyptus and Corymbia seeds [PDF]

Ciência 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

Hippocampal gene expression is modulated by hypergravity [PDF]

European Journal of Neuroscience, 2004
AbstractWe used the cDNA microarray technique to monitor simultaneously possible changes induced by hypergravity in the expression level of thousands of hippocampal genes. We tested the mRNA level of about 5000 genes in the hippocampus of mice subjected to 1.09 g (1g) or to 1.85 g (2g) for five repeated 1‐h daily rotations in a centrifuge (g = 9.81 m ...

Hypergravity as a Tool for Cell Stimulation: : Implications in Biomedicine [PDF]

Frontiers in Astronomy and Space Sciences, 2016
Gravity deeply influences numerous biological events in living organisms. Variations in gravity values induce adaptive reactions that have been shown to play important roles, for instance in cell survival, growth, and spatial organization. In this paper,

An instrumented centrifuge for studying mouse locomotion and behaviour under hypergravity [PDF]

Biology Open, 2019
Gravity may influence multiple aspects of legged locomotion, from the periods of limbs moving as pendulums to the muscle forces required to support the body.
