    • Improved Temporal Stability of Polymethine Laser Dyes in Aqueous Solutions 

      Hackett, C.E.; Dewey, C.F. Jr (Institute of Electrical and Electronic Engineers, 1973)
      Polymethine laser dyes which fluoresce in the near infrared in organic solvents generally exhibit poor temporal stability at room temperature. Two typical laser-pumped polymethine dyes in aqueous solutions containing ...

    • Interpreting Photoactive Fluorescence Microscopy Measurements of Steady-State Actin Dynamics 

      Tardy, Y.; McGrath, J.L.; Hartwig, J.H.; Dewey, C.F. (Biophysical Society, 1995)
      A continuum model describing the steady-state actin dynamics of the cytoskeleton of living cells Has been developed to aid in the interpretation of photoactivated fluorescence experiments. In a simplified cell geometry, ...

    • Lasing Efficiency and Photochemical Stability of IR Laser 

      Oettinger, Peter E.; Dewey, C. Forbes Jr (Institute of Electrical and Electronic Engineers, 1976)
      The lasing efficiencies and photochemical stabilities of laser dyes useful in the 710-1080-nm spectral region have been investigated using a Q-switched ruby laser pumping source. The measured bleaching rates P defined ...

    • A Mechanistic Model of the Actin Cycle 

      Bindschadler, M.; Osborn, E. A.; Dewey, C. F. Jr; McGrath, J. L. (Biophysical Society, 2004-05)
      We have derived a broad, deterministic model of the steady-state actin cycle that includes its major regulatory mechanisms. Ours is the first model to solve the complete nucleotide profile within filaments, a feature that ...

    • Pressure Dependence of the Infrared Laser Lines in Barium Vapor 

      Madigan, M.; Hocker, L.O.; Flint, J.H.; Dewey, C.F. Jr (Institute of Electrical and Electronic Engineers, 1980)
      We have studied nine laser transitions in Ba vapor at wavelengths between 1.13 and 3.05 micrometer. Three of these laser lines have not been reported previously. The relative intensities of the four strongest transitions ...

    • Regulation of Adenine Nucleotide Concentration at Endothelium-Fluid Interface by Viscous Shear Flow 

      Shen, Jian; Gimbrone, Michael A. Jr.; Luscinskas, Francis W.; Dewey, C. Forbes Jr. (Biophysical Society, 1993)
      The action of adenine nucleotides on vascular endothelial cells is apparently mediated by the local flow conditions. Because nucleotides are sequentially degraded from ATP - ADP - AMP -- adenosine by ecto-enzymes at the ...

    • Simultaneous Measurements of Actin Filament Turnover, Filament Fraction, and Monomer Diffusion in Endothelial Cells 

      McGrath, J. L.; Tardy, Y.; Dewey, C. F. Jr; Meister, J. J.; Hartwig, J. H. (Biophysical Society, 1998-09)
      The analogous techniques of photoactivation of fluorescence (PAF) and fluorescence recovery after photobleaching (FRAP) have been applied previously to the study of actin dynamics in living cells. Traditionally, ...

    • Theoretical Estimates of Mechanical Properties of the Endothelial Cell Cytoskeleton 

      Satcher, Robert L. Jr.; Dewey, C. Forbes Jr. (Biophysical Society, 1996)
      Current modeling of endothelial cell mechanics does not account for the network of F-actin that permeates the cytoplasm. This network, the distributed cytoplasmic structural actin (DCSA), extends from apical to basal ...
