Cellular responses to micro- and hypergravity are rapid complex appear within the first few seconds of exposure. Transcriptomic analyses a valuable tool analyze these genome-wide cellular alterations. For better understanding dynamics upon altered gravity exposure, it is important compare different time points. However, since most experiments designed as endpoint measurements, combination cross...

We conducted the Resist Tubule space experiment to clarify role of cell wall in resistance inflorescence stems Arabidopsis (Arabidopsis thaliana) gravitational acceleration Cell Biology Experiment Facility on Kibo Module International Space Station. The rigidity was lower under microgravity conditions than at 1g, particularly basal region, which plays a central supporting entire plant presence ...

Multiple transitions between gravity levels will occur during planetary exploration missions. In reaction to these gravitational transitions, physiological adaptation be initiated. However, the effects of long-duration exposures hypogravity and hypergravity are poorly understood. this review we present an overview how humans perceive gravity, sex-based differences in changes introduces rather l...

Hypergravity accelerators are a type of large machinery used for gravity training or medical research. A failure such equipment can be serious problem in terms safety costs. This paper proposes prediction model that proactively prevent failures may occur hypergravity accelerator. An experiment was conducted to evaluate the performance method proposed this paper. 4-channel accelerometer attached...

The effect of artificial gravity on the growth of a microorganism, Dictyostelium discoideum, was studied and the following results were obtained: (a) Germination efficiency increased as gravity increased up to 3 gravities. (b) Cell differentiation was influenced by gravity. Retardation of spore formation or reduction in the spore fraction was observed at hypergravity. (c) Fruiting bodies were t...

To elucidate the pure impact of microgravity on small mammals despite uncontrolled factors that exist in the International Space Station, it is necessary to construct a 1 g environment in space. The Japan Aerospace Exploration Agency has developed a novel mouse habitat cage unit that can be installed in the Cell Biology Experiment Facility in the Kibo module of the International Space Station. ...

In order to measure the perceived direction of "up", subjects judged the three-dimensional shape of disks shaded to be compatible with illumination from particular directions. By finding which shaded disk appeared most convex, we were able to infer the perceived direction of illumination. This provides an indirect measure of the subject's perception of the direction of "up". The different cues ...

The planning and control of motor actions requires knowledge of the dynamics of the controlled limb to generate the appropriate muscular commands and achieve the desired goal. Such planning and control imply that the CNS must be able to deal with forces and constraints acting on the limb, such as the omnipresent force of gravity. The present study investigates the effect of hypergravity induced...

Every living organism on earth has developed and evolved in unit gravity (1G) conditions. It is likely that any deviation from earth’s standard gravity will influence development, particularly at early stages. Previous reports from this lab showed that total length is reduced and that ventricle size is increased during development at 7G. The objective of the present study was to investigate the...
