      Multiscale, structure-based modeling for the elastic mechanical behavior of arterial walls 

      Barocas, V. Η; Stylianopoulos, T. (2007)
      Passive elastic behavior of arterial wall remains difficult to model. Although phenomenological and structural models exist, the question of how the three-dimensional network structure of the collagen in the artery determines ...

      Mutation analysis of coding sequences for type I procollagen in individuals with low bone density 

      Spotila, L. D.; Colige, A.; Sereda, L.; Constantinou-Deltas, Constantinos D.; Whyte, M. P.; Riggs, L. B.; Shaker, J. L.; Spector, T. D.; Hume, E.; Olsen, N.; Attie, M.; Tenenhouse, A.; Shane, E.; Briney, W.; Prockop, D. J. (1994)
      Mutations in one of the two genes encoding type I procollagen (COL1A1 and COL1A2) are frequently the cause of osteogenesis imperfecta (OI), a disorder characterized by brittle bones. Here we tested whether patients with ...

      Mutation in a gene for type I procollagen (COL1A2) in a woman with postmenopausal osteoporosis: Evidence for phenotypic and genotypic overlap with mild osteogenesis imperfecta 

      Spotila, L. D.; Constantinou-Deltas, Constantinos D.; Sereda, L.; Ganguly, A.; Riggs, B. L.; Prockop, D. J. (1991)
      Mutations in the two genes for type I collagen (COL1A1 or COL1A2) cause osteogenesis imperfecta (OI), a heritable disease characterized by moderate to extreme brittleness of bone early in life. Here we show that a 52-year-old ...
