Background and Aim: Motion sickness (MS) is usually generated when there is a mismatch between the senses which serve balance. One of these senses is related to vestibular system, so it is highly possible that MS reflects in vestibular test results. But there are some conflicts in correlation between vestibular findings and MS. Thus, the objective of this study was to provide an overview of ves...

(1490-2510 ng/dl) the marrow iron score was only 2 + (nondialysis control value). 1-3 In previous studies of serum ferritin and marrow iron, no attempt was made to investigate iron overload in the liver and spleen. In the absence ofhepatosplenic siderosis the marrowiron stores can be expected to represent total-body iron stores, and iron-depleted marrow can be regarded as evidence of iron defic...

Motion sickness (MS) is an unpleasant and sometimes disabling condition in response to the perception of certain kind of motions. Its pathogenesis is incompletely understood; interactions between endocrine mechanisms and the vestibular apparatus are likely, as suggested by a higher incidence and severity of MS in females and pregnancy, the reported changes in MS susceptibility during the menstr...

Motion sickness is known under several names in different domains, such as seasickness, carsickness, cybersickness, and simulator sickness. As we will argue, these can all be considered manifestations of one common underlying mechanism. In recent years, it has received renewed interest, largely due to the advent automated vehicles developments virtual reality, particular using head-mounted disp...

Sensory conflict has been used to explain the way we perceive and control our self-motion, as well as the aetiology of motion sickness. However, recent research on simulated viewpoint jitter provides a strong challenge to one core prediction of these theories -- that increasing sensory conflict should always impair visually induced illusions of self-motion (known as vection). These studies show...

This paper investigates the fundamentals of motion planning for minimizing sickness in transportation systems higher automation levels. The optimum velocity profile is sought a predefined road path from specific starting point to final one within and given boundaries constraints order minimize journey time. An empirical approach based on British standard used evaluate sickness. trade-off betwee...

Nausea is a prominent symptom and major cause of complaint for patients receiving anticancer chemo- or radiation therapy. The arsenal of anti-nausea drugs is limited, and their efficacy is questionable. Currently, the development of new compounds with anti-nausea activity is hampered by the lack of physiological correlates of nausea. Physiological correlates are needed because common laboratory...

One of the Skylab experiments dealt with motion sickness, comparing susceptibility in the workshop aloft with susceptibility preflight and postflight. Tests were conducted on and after mission-day 8 (MD 8) by which time the astronauts were adapted to working conditions. Stressful accelerations were generated by requiring the astronauts, with eyes covered, to execute standardized head movements ...

Many studies have demonstrated sex and age differences in motion sickness, but the underlying physiological basis is still in controversy. In the present study, we tried to investigate the potential correlates of endocrine and/or neuronal activity with sex and age differences in rats with motion sickness. LiCl-induced nausea symptom was evaluated by conditioned gaping. Motion sickness was asses...
