Transcriptomic Response of Drosophila Melanogaster Pupae Developed in Hypergravity [PDF]

, 2016
The metamorphosis of Drosophila is evolutionarily adapted to Earth's gravity, and is a tightly regulated process. Deviation from 1g to microgravity or hypergravity can influence metamorphosis, and alter associated gene expression.

Differential intestinal injury and unchanged systemic inflammatory responses to leg and whole‐body passive hyperthermia in healthy humans

Experimental Physiology, EarlyView.
Abstract Hyperthermia can cause intestinal injury, facilitating endotoxin translocation and an inflammatory response that has been associated with heat illness. However, the potential occurrence of these responses has been incompletely reported during passive hyperthermia, and the independent effect of hyperthermia is equivocal.

Effect of hypergravity on the biomechanics of the musculoskeletal system in human lumbar spine: a numerical study

Frontiers in Bioengineering and Biotechnology
The aim of this study was to investigate the effects of hypergravity on the biomechanics of the human lumbar spinal musculoskeletal system. We quantitatively analyzed the biomechanics of the intervertebral disc (IVD), lumbar spinal muscles, and ligament ...

The Impact of Altered Gravity and Vibration on Endothelial Cells During a Parabolic Flight

Cellular Physiology and Biochemistry, 2013
Background: Endothelial cells (EC) cultured under altered gravity conditions show a cytoskeletal disorganization and differential gene expression (short-term effects), as well as apoptosis in adherently growing EC or formation of tubular 3D structures ...

Hypergravity Increases Blood–Brain Barrier Permeability to Fluorescent Dextran and Antisense Oligonucleotide in Mice

Cells, 2023
The earliest effect of spaceflight is an alteration in vestibular function due to microgravity. Hypergravity exposure induced by centrifugation is also able to provoke motion sickness.

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

MCA1 and MCA2 Are Involved in the Response to Hypergravity in Arabidopsis Hypocotyls

Plants, 2020
Plants respond to and resist gravitational acceleration, but the mechanism of signal perception in the response is unknown. We studied the role of MCA (mid1-complementing activity) proteins in gravity perception by analyzing the expression of the MCA1 ...
