Research advance in effects of weightlessness or simulated weightlessness on tumor cells.
Zhongguo yi xue ke xue yuan xue bao. Acta Academiae Medicinae Sinicae, 2014Weightless environment is a rare phenomenon on the ground where the interactions among cells and internal cellular structures disappear or become weakened. Studies on the biological features and molecular expression of tumors cells in weightlessness condition may provide new clues to the tumor initiation, process, diagnosis, and therapy.

Amino acid supplementation alters bone metabolism during simulated weightlessness
Journal of Applied Physiology, 2005High-protein and acidogenic diets induce hypercalciuria. Foods or supplements with excess sulfur-containing amino acids increase endogenous sulfuric acid production and therefore have the potential to increase calcium excretion and alter bone metabolism.

Simulated weightlessness for the ontogenesis of the otolith organ
Die Naturwissenschaften, 1968Abstract : The critical phase of the otolith-organ-ripening within the embryo was used in a simulation experiment by setting frog eggs (Rana temporaria) and toad eggs (Bufo bufo) near the center of a rotating system with a horizontal axis. The experiment speeds were 100 and 160 r.p.m.; the eggs and tadpoles were subjected to maximal centripetal forces ...

[Adaptation of myocardial function to simulated weightlessness].
Hang tian yi xue yu yi xue gong cheng = Space medicine & medical engineering, 1998To observe the changes in myocardial function and calcium ion release of sarcoplasmic reticulum in rats under simulated weightlessness, 24 Sprague-Dawley male rats were divided into control (CON), 8 week tail-suspension (SUS) and recovery for 2 weeks (RE) groups. The results showed that there was no change in resting tension of myocardial twitch in SUS.

Effects of simulated weightlessness on bone properties in rats
Journal of Biomechanics, 1990Abstract This paper addresses two questions: (1) are reductions in bone apposition rate during disuse due to increased periods of ‘resting’ during bone formation? and (2) are diaphyseal strength changes due to disuse caused by changes in the quality as well as the quantity of the bone matrix?

Computational simulation to understand vision changes during prolonged weightlessness
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013A mathematical model of whole body and cerebral hemodynamics is a useful tool for investigating visual impairment and intracranial pressure (VIIP), a recently described condition associated with space flight. VIIP involves loss of visual acuity, anatomical changes to the eye, and, usually, elevated cerebrospinal fluid pressure. Loss of visual acuity is
