Vestibulospinal Adaptation to Microgravity
Otolaryngology–Head and Neck Surgery, 1998Human balance control is known to be transiently disrupted after spaceflight; however, the mechanisms responsible for postflight postural ataxia are still under investigation. In this report, we propose a conceptual model of vestibulospinal adaptation based on theoretical adaptive control concepts and supported by the results from a comprehensive study

Growing tissues in microgravity
Nature Medicine, 1998The possibility of creating three-dimensional differentiated tissue-like assemblies by culturing cells in microgravity, either in space or on the ground, offers research opportunities that may lead to the generation of replacement organs for transplantation, and for studying multicellular responses in toxicology, radiation biology, tumorigenesis, and ...

Microgravity tissue engineering
In Vitro Cellular & Developmental Biology - Animal, 1997Tissue engineering studies were done using isolated cells, three-dimensional polymer scaffolds, and rotating bioreactors operated under conditions of simulated microgravity. In particular, vessel rotation speed was adjusted such that 10 mm diameter x 2 mm thick cell-polymer constructs were cultivated in a state of continuous free-fall.

Determinants of orientation in microgravity
Acta Astronautica, 1992During two parabolic flight campaigns, one with the NASA-KC-135, the second with the ESA Caravelle, human spatial orientation in an altered gravitational environment was studied by measuring the subjective visual vertical (SVV) by means of a luminous line, and by asking the subjects to give a report, with eyes closed, about their orientation to ...

Preparation for microgravity - The role of the Microgravity MaterialScience Laboratory
Space Programs and Technologies Conference, 1988A laboratory dedicated to ground based materials processing in preparation for space flight was established at the NASA Lewis Research Center. Experiments are performed to delineate the effects of gravity on processes of both scientific and commercial interest. Processes are modeled physically and mathematically.

Abstract Microgravity is the state of near-weightlessness that exists within a spacecraft which is in orbit around the Earth or has achieved escape velocity and is on its way towards other planets. The gravity on Earth is used as the standard measurement- I g-and the gravity experienced in a spacecraft is expressed as a fraction of ...

Amphibian Amplexus in Microgravity
Zoological Science, 1995We report here on the amplectic behavior of the Japanese treefrog (Hyla japonica) in microgravity. Treefrogs were exposed to 35 cycles of altered gravity, including approximately 1.5 sec of G < 0.1 every 3 min and 15 sec, on the FreeFall "G.0" ride at Space World amusement park in Kitakyushu, Japan.

Proteomics and genomics of microgravity
Physiological Genomics, 2006Many serious adverse physiological changes occur during spaceflight. In the search for underlying mechanisms and possible new countermeasures, many experimental tools and methods have been developed to study microgravity caused physiological changes, ranging from in vitro bioreactor studies to spaceflight investigations. Recently, genomic and proteomic
