Alterations in gut transport of minerals and in binding proteins during simulated weightlessness [PDF]

open access: green, 1984
The structural components of the skeleton develop and are maintained in a 1 g environment, shaped by the mechanical load to which they are constantly exposed.

Simulated weightlessness in fish and neurophysiological studies on memory storage [PDF]

open access: green, 1973
Simulated weightlessness was used to study the different types of gravity responses in blind fish. It was found that a shift in the direction of low magnitude acceleration in weightlessness causes a rapid 180 deg turn in the blind fish, while a shift in ...

SIMULATED WEIGHTLESSNESS LED TO THE TRANSFORMATION OF GLYCOLIPID METABOLISM IN THE LIVERS OF MICE

open access: yesRevista Brasileira de Medicina do Esporte, 2023
Objectives: The effects of weightlessness on the liver were studied using a tail suspension (TS) male mouse model. Methods: The effects of 0-, 2- and 4-week TS (CON, TS2 and TS4 groups) on glycogen and lipid content, as well as on the molecular processes

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 ...

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 ...
