Study of histopathological and molecular changes of rat kidney under simulated weightlessness and resistance training protective effect. [PDF]

open access: yesPLoS ONE, 2011
To explore the effects of long-term weightlessness on the renal tissue, we used the two months tail suspension model to simulate microgravity and investigated the simulated microgravity on the renal morphological damages and related molecular mechanisms.

Artificial Gravity as a Bone Loss Countermeasure in Simulated Weightlessness

open access: hybridThe FASEB Journal, 2007
The impact of microgravity on the human body is a significant concern for space travelers. We report here initial results from a pilot study designed to explore the utility of artificial gravity (AG) as a countermeasure to the effects of microgravity, specifically to bone loss.

Angelicae dahuricae radix alleviates simulated microgravity induced bone loss by promoting osteoblast differentiation [PDF]

open access: yesnpj Microgravity
Bone loss caused by long-duration spaceflight seriously affects the skeletal health of astronauts. There are many shortcomings in currently available treatments for weightlessness-induced bone loss.

Cellular and Molecular Effects of Microgravity on the Immune System: A Focus on Bioactive Lipids [PDF]

open access: yesBiomolecules
Microgravity is one of the main stressors that astronauts are exposed to during space missions. This condition has been linked to many disorders, including those that feature dysfunctional immune homeostasis and inflammatory damage.

Simulated microgravity affects carrageenan-induced inflammation process in rats [PDF]

open access: yesPharmacia, 2023
Weightlessness significantly impacts physiological systems. In the current study, we investigate the effects of 7 days exposure of rats to simulated microgravity (using a modified rat-modeled random positioning machine, working with four experimental ...

Protective effects of ginsenosides Rg1 and Rb1 against cognitive impairment induced by simulated microgravity in rats

open access: yesFrontiers in Pharmacology, 2023
Microgravity experienced during space flight is known to exert several negative effects on the learning ability and memory of astronauts. Few effective strategies are currently available to counteract these effects.

Cell proliferation, cell shape, and microtubule and cellulose microfibril organization of tobacco BY-2 cells are not altered by exposure to near weightlessness in space [PDF]

open access: yes, 2009
The microtubule cytoskeleton and the cell wall both play key roles in plant cell growth and division, determining the plant’s final stature. At near weightlessness, tubulin polymerizes into microtubules in vitro, but these microtubules do not self ...
