Differential Impact of Social Isolation and Space Radiation on Behavior and Motor Learning in Rats [PDF]

Life, 2023
Future missions to Mars will expose astronauts to several physical and psychological challenges, including exposure to space radiation (SR) and periods of social isolation (SI). Each of these stressors, in addition to mission demands, can affect physical

Space Radiation Biology for "Living in Space". [PDF]

Biomed Res Int, 2020
Space travel has advanced significantly over the last six decades with astronauts spending up to 6 months at the International Space Station. Nonetheless, the living environment while in outer space is extremely challenging to astronauts. In particular, exposure to space radiation represents a serious potential long‐term threat to the health of ...

MicroRNAs Responding to Space Radiation. [PDF]

Int J Mol Sci, 2020
High-energy and high-atom-number (HZE) space radiation poses an inevitable potential threat to astronauts on deep space exploration missions. Compared with low-LET radiation, high-energy and high-LET radiation in space is more efficient in inducing clustered DNA damage with more serious biological consequences, such as carcinogenesis, central nervous ...

Neuroinflammatory Signaling and Immune Cell Infiltration Differ in Brains of Rats Exposed to Space Radiation and Social Isolation [PDF]

Life
Astronauts on the proposed Mars missions will be exposed to extended periods of social isolation (SI) and space radiation (SR). SI and SR-induced immune dysregulation can result in persistent neuroinflammation and neuronal damage which could negatively ...

Alterations in Blood–Brain Barrier Integrity and Lateral Ventricle Differ in Rats Exposed to Space Radiation and Social Isolation [PDF]

Life
The proposed Mars missions will expose astronauts to long durations of social isolation (SI) and space radiation (SR). These stressors have been shown to alter the brain’s macrostructure and microenvironment, including the blood–brain barrier (BBB ...
