Proton-Pumping Capabilities of the M-Fast and M-Slow Photocycles of Bacteriorhodopsin

October 12, 2021
Author(s)
R W. Hendler, John Kakareka, P D. Smith, T J. Pohida, Curtis W. Meuse
The parallel model for the bacteriorhodopsin (BR) photocycle at neutral pH and a temperature near 20 contains an M-fast cycle with steps BR >K >L >Mf >N >O >BR and an M-slow cycle which contains steps BR >K >L >Ms >BR. With increasing actinic laser

Further Studies with Isolated Absolute Infrared Spectra of Bacteriorhodopsin Photocycle Intermediates: Conformational Changes and Possible Role of a New Proton-Binding Center

January 1, 2013
Author(s)
Richard W. Hendler, Curtis W. Meuse, Paul Smith, John W. Kakareka
We recently published procedures describing the isolation of absolute infrared spectra for the intermediates of the bacteriorhodopsin (BR) photocycle and from these, obtaining transitional difference spectra between consecutive intermediates. In that work

International Comparability in Circular Dichroism: II

October 4, 2010
Author(s)
Curtis W. Meuse, Jascindra Ravi, Paulina Rakowska, Tommaso Garfagnini, Alex E. Knight, Philippe Charlet, Julie D. Lorenz, Christopher Jones, David F. Plusquellic, Frank Wien, Liqing Wu
A previous inter-laboratory study, CCQM P59, showed that there was a poor level of comparability between laboratories in circular dichroism spectroscopy. In a follow-up study reported here, we achieved our goal of demonstrating improved comparability and

Interaction of Gold Nanoparticles with Common Human Blood Proteins

December 18, 2009
Author(s)
Silvia H. De Paoli Lacerda, Jung J. Park, Curtis W. Meuse, Denis Pristinski, Matthew Becker, Jack F. Douglas
Gold nanoparticles (NPs) provide a promising platform for diagnostics and therapy, as well as other biomedical applications. The recent literature, however, contains conflicting data regarding the cytotoxicity of NPs. We have thus performed an array of

The Stiffness of Collagen Fibrils Influences Vascular Smooth Muscle Cell Phenotype

March 1, 2007
Author(s)
Dennis P. McDaniel, Gordon A. Shaw, John T. Elliott, Kiran Bhadriraju, Curtis W. Meuse, Koo-Hyun Chung, Anne L. Plant
Cells receive signals from the extracellular matrix through receptor-dependent interactions, but they are also influenced by the mechanical properties of the matrix. While bulk properties of substrates have been shown to effect cell behavior, we show here

Surface-Plasmon-Resonance-Enhanced Cavity Ring-Down Detection

January 1, 2004
Author(s)
A C. Pipino, John T. Woodward IV, Curtis W. Meuse, Vitalii I. Silin
The cavity ring-down technique is used to probe the absolute optical response of the localized surface plasmon resonance (SPR) of a gold nanoparticle distribution to adsorption of trichloroethylene (TCE) and perchloroethylene (PCE) from the gas phase

Osteoblast Cell Membrane Hybrid Bilayers for Studying Cell-Cell Interactions

September 30, 2003
Author(s)
John T. Elliott, Alessandro Tona, John T. Woodward IV, Curtis W. Meuse, H M. Elgendy, Anne L. Plant
Osteopath-like cells were grown on a surface that presents cell membrane components to the cells in culture. The culture surface was a bilayer formed by the interaction of osteoblast plasma membrane vesicles with an alkanethiol monolayer. We examined the

Biomimetic Membranes on Metal Supports

May 1, 2003
Author(s)
John T. Elliott, Curtis W. Meuse, Vitalii I. Silin, Susan T. Krueger, John T. Woodward IV, T Petralli-Mallow, Anne L. Plant
Biological membranes are complex and dynamic structures. The biological functions associated with membranes involve a number of different molecular species, and theories of how the molecular species are organized are still evolving. The fluid mosaic model

Isostructural Self-Assembled Monolayers, Part 1. Octadecyl 1-thiaoligo(ethylene oxides)

April 1, 2003
Author(s)
David J. Vanderah, Richard S. Gates, Vitalii I. Silin, D N. Zeiger, John T. Woodward IV, Curtis W. Meuse, Gintaras Valincius, B Nickel
The self-assembled monolayers (SAMs) of a series of octadecyl 1-thiaoligo(ethylene oxide)x disulfides {[S(CH 2CH 2O) xC 18H 37] 2}, where x = 4 to 8, were assembled on gold and characterized by reflection-adsorption infrared spectroscopy (RAIRS)

Helical, Disordered, and What that Means: Structural Characterization of a New Series of Methyl 1-Thiaoligo(Ethylene Oxide) Self-Assembled Monolayers

September 1, 2002
Author(s)
David J. Vanderah, J Arsenault, H La, Vitalii I. Silin, Curtis W. Meuse, Richard S. Gates
Self-assembled monolayers (SAMs) of a series of linear thiols containing a 1-thiaoligo(ethylene oxide) [TOEO] moiety, i.e., HS(CH2CH2O)xCH3, where x = 3 - 6, were prepared on polycrystalline gold (Au) and characterized by reflection adsorption infrared

Molecular Dynamics Study of Partial Monolayer Ordering of Chain Molecules

October 1, 2001
Author(s)
Raymond D. Mountain, Joseph B. Hubbard, Curtis W. Meuse, V Simmons
We present the results of a molecular dynamics study of a partial monolayer of self-assembled octadecanethiol molecules. The correlations between various statistical measures of surface induced chain ordering are examined. These include the density profile
