Abstract: The oral health of astronauts, last studied in the mid- 1970s on Skylab, has not been a priority area of study for NASA due to the short length of shuttle stays. But with longer stays on the International Space Station, and ... NASA Center: Goddard Space Flight Center Publication Year: 2004 Added to NTRS: 2008-06-02 Document ID: 20050169462 Experiment K-6-06. Morphometric and EM analyses of tibial epiphyseal plates from Cosmos 1887 rats Author(s): Duke, P. J.; Montufar-Solis, D.; Durnova, G. Abstract: Light and electron microscopy studies were carried out on decalcified tibial epiphyseal plates of rats flown aboard Cosmos 1887 (12.5d flight plus 53.5h recovery). Analysis of variance showed that the proliferative zone of ... NASA Center: NASA (non Center Specific) Publication Year: 1990 Added to NTRS: 2008-05-31 Accession Number: 90N26460; Document ID: 19900017144 Human Bone-Forming Chondrocytes Cultured in the Hydrodynamic Focusing Bioreactor Retain Matrix Proteins: Similarities to Spaceflight Results Author(s): Duke, P. J.; Hecht, J.; Montufar-Solis, D. Abstract: Fracture healing, crucial to a successful Mars mission, involves formation of a cartilaginous fracture callus which differentiates, mineralizes, ossifies and remodels via the endochondral process. Studies of spaceflown and ... NASA Center: Johnson Space Center Publication Year: 2006 Added to NTRS: 2007-08-03 Document ID: 20070022678 Studies of chondrogenesis in rotating systems Author(s): Duke, P. J.; Daane, E. L.; Montufar-Solis, D. Abstract: A great deal of energy has been exerted over the years researching methods for regenerating and repairing bone and cartilage. Several techniques, especially bone implants and grafts, show great promise for providing a remedy ... NASA Center: NASA (non Center Specific) Publication Year: 1993 Added to NTRS: 2006-08-02 Document ID: 20050000501 Histomorphometric and electron microscopic analyses of tibial epiphyseal plates from Cosmos 1887 rats Author(s): Duke, P. J.; Durnova, G.; Montufar-Solis, D. Abstract: Previous studies have shown that the changes seen in the bones of growing rats exposed to microgravity are due in part to changes that occur in the growth plate during spaceflight. In this study, growth plates of rats flown ... NASA Center: NASA (non Center Specific) Publication Year: 1990 Added to NTRS: 2006-08-02 Document ID: 20050000884 The Spacelab 3 simulation: basis for a model of growth plate response in microgravity in the rat Author(s): Montufar-Solis, D.; Duke, P. J.; Morey-Holton, E. Abstract: Data from Spacelab 3 (SL3) suggested that spaceflight significantly reduces the activity of the rat tibial growth plate. Animal processing after SL3 began twelve hours post-landing, so data reflect post-flight re-adaptation ... NASA Center: NASA (non Center Specific) Publication Year: 2001 Added to NTRS: 2006-08-02 Document ID: 20040088061 Galacturonomannan and Golgi-derived membrane linked to growth and shaping of biogenic calcite Author(s): Marsh, M. E.; Ridall, A. L.; Azadi, P.; Duke, P. J. Abstract: The coccolithophores are valuable models for the design and synthesis of composite materials, because the cellular machinery controlling the nucleation, growth, and patterning of their calcitic scales (coccoliths) can be ... NASA Center: NASA (non Center Specific) Publication Year: 2002 Added to NTRS: 2006-08-02 Document ID: 20040088053 Proteoglycans in micromass cultures of embryonic mouse limb mesenchymal cells: preliminary studies for the "cells" spaceflight experiment Author(s): Montufar-Solis, D.; Duke, P. J. Abstract: No abstract available NASA Center: NASA (non Center Specific) Publication Year: 1992 Added to NTRS: 2006-08-02 Document ID: 20050000793 Growth and differentiation of mammalian embryonic tissues exposed to hypergravity in vivo and in vitro Author(s): Duke, P. J. Abstract: In about 10 years or so, men and women from Earth will be long-term inhabitants of a space station aboard which plants and animals will be growing and developing in gravities other than that of Earth. The effect of ... NASA Center: NASA (non Center Specific) Publication Year: 1984 Added to NTRS: 2004-11-03 Accession Number: 84N18869; Document ID: 19840010801 Chondrogenesis in Cultures of Embryonic Mouse Limb Mesenchyme Exposed to Microgravity Author(s): Duke, P. J.; Montufar-Solis, D.; Daane, E. Abstract: The effects of exposure to microgravity on cartilage development are important Introduction because of the critical role of chondrogenesis in shaping the skeleton through the process of endochondral ossification. In vivo ...
