The Effects of Chronic Weightlessness on Limited of Stability and Dynamic Balance in ‎Breath-hold and SCUBA Divers [PDF]

Journal of Paramedical Science and Rehabilitation, 2022
Purpose:Water immersion built a new environment in which weightlessness puts unknown demand on somatosensory system such as altered sensory integration due to the improper proprioception afferent. This condition can lead to an imprecise function of human

Müller cells are activated in response to retinal outer nuclear layer degeneration in rats subjected to simulated weightlessness conditions

Neural Regeneration Research
A microgravity environment has been shown to cause ocular damage and affect visual acuity, but the underlying mechanisms remain unclear. Therefore, we established an animal model of weightlessness via tail suspension to examine the pathological changes ...

Effects of 15-Days −6° Head-Down Bed Rest on the Attention Bias of Threatening Stimulus

Frontiers in Psychology, 2022
Previous researchers have found that head-down bed rest (HDBR) will affect the emotional state of individuals, and negative emotions such as anxiety are closely related to attention bias.

High-gradient magnetic fields and starch metabolism: results from a space experiment

Scientific Reports, 2022
Directing plant growth in weightlessness requires understanding the processes that establish plant orientation and how to manipulate them. Both gravi- and phototropism determine directional growth and previous experiments showed that high gradient ...
