  1. ncbi request reprint Enhanced three-dimensional deconvolution microscopy using a measured depth-varying point-spread function
    Joshua W Shaevitz
    Department of Integrative Biology, University of California, Berkeley 94720, USA
    J Opt Soc Am A Opt Image Sci Vis 24:2622-7. 2007
    ..We present simple convolution and deconvolution algorithms that use the full depth-varying point-spread functions and use these to demonstrate a reduction of elongation artifacts in a reconstructed image of a 2 microm sphere...
  2. pmc Curvature and torsion in growing actin networks
    Joshua W Shaevitz
    Department of Integrative Biology, University of California, Berkeley, Berkeley, CA, USA
    Phys Biol 5:026006. 2008
    ..These results suggest that paths of actin-propelled objects may be attributed to slow changes in curvature, possibly associated with filament debranching, rather than a fixed torque...
  3. pmc Load fluctuations drive actin network growth
    Joshua W Shaevitz
    Department of Integrative Biology, University of California, Berkeley, CA 94720, USA
    Proc Natl Acad Sci U S A 104:15688-92. 2007
    ..This conclusion is supported by Monte Carlo simulations of an adhesion-based BR and suggests an important role for membrane tension in the control of actin-based cellular protrusions...
  4. pmc The bacterial actin MreB rotates, and rotation depends on cell-wall assembly
    Sven van Teeffelen
    Department of Molecular Biology, Princeton University, Princeton, NJ 08544, USA
    Proc Natl Acad Sci U S A 108:15822-7. 2011
    ..These findings both broaden the view of cytoskeletal motors and deepen our understanding of the physical basis of bacterial morphogenesis...

    Elio A Abbondanzieri
    Department of Applied Physics, Stanford University, Stanford, California 94305, USA
    Nature 438:460-5. 2005
    ..Global fits were inconsistent with a model for movement incorporating a power stroke tightly coupled to pyrophosphate release, but consistent with a brownian ratchet model incorporating a secondary NTP binding site...

    Elio A Abbondanzieri
    Department of Applied Physics, Stanford University, Stanford, California 94305, USA
    Biophys J 89:L61-3. 2005
    ..In contrast, we found little change in either the frequency or the lifetime of off-pathway, paused states, indicating that the energetic barrier to transcriptional pausing is predominantly entropic...

    Proc Natl Acad Sci U S A 100:2351-6. 2003
    ..Fluctuation analysis shows that the cycle contains at least four transitions, and confirms that hydrolysis remains tightly coupled to stepping. Together, our findings pose challenges for models of kinesin motion...
