The Effects of Coriolis Acceleration during Zero-gravity Parabolic Flight.
Twenty-one normal and four labyrinthine defective (L-D) subjects were exposed to repetitive, twenty-second intervals of (1) zero gravity or (2) zero gravity plus Coriolis acceleration in parabolic flight. The normal subjeets showed significant hematological and biochemieaI evidence of stress in the form of leukoeytic changes and alteration in excretion rates of eorticosteroids, while the L-D gr...
متن کاملRegional difference of blood flow in anesthetized rats during reduced gravity induced by parabolic flight.
To examine a hypothesis that change in regional blood flow due to decreased hydrostatic pressure gradient and redistribution of blood during reduced gravity (rG) is different between organs, changes in cerebrocortical blood flow (CBF) and blood flow in the temporal muscle (MBF) with exposure to rG were measured in anesthetized rats in head-up tilt and flat positions during parabolic flight. Car...
متن کاملPostnatal development of spatial coding in the gravity sensing system
The critical maturation time of central otolith neurons in processing spatial orientations was examined in Sprague-Dawley rats. With the use of immuno-hybridization histochemical methods, we observed c-fos expression in vestibular nuclear neurons responding to transverse movement on the horizontal plane as early as P7 and those to antero-posterior stimulation as early as P9. In the inferior oli...

متن کاملThe impact of altered gravity and vibration on endothelial cells during a parabolic flight.
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 (long-term effects). METHODS Investigating short-term effects of real microgravity, we exposed EC to parabolic flight maneuvers and analysed the...
