Journal ArticleDOI
Direct magnetic resonance detection of myelin and prospects for quantitative imaging of myelin density
Michael J. Wilhelm,Henry H. Ong,Suzanne Wehrli,Cheng Li,Ping Huei Tsai,David B. Hackney,Felix W. Wehrli +6 more
TL;DR: The integrated signal from myelin suspensions is shown, both spectroscopically and by imaging, to scale with concentration, suggesting the potential for quantitative determination of myelin density.
Journal ArticleDOI
Gram's Stain Does Not Cross the Bacterial Cytoplasmic Membrane.
Michael J. Wilhelm,Joel B. Sheffield,Mohammad Sharifian Gh.,Yajing Wu,Christian Spahr,Grazia Gonella,Bolei Xu,Hai-Lung Dai +7 more
TL;DR: A real-time and membrane specific quantitative characterization of the bacterial uptake of crystal-violet (CV), the dye used in Gram's protocol, indicates that CV, rather than dyes which rapidly traverse the PM, is uniquely suited as the Gram stain.
Journal ArticleDOI
Adsorption and transport of charged vs. neutral hydrophobic molecules at the membrane of murine erythroleukemia (MEL) cells.
TL;DR: The adsorption and transport of hydrophobic molecules at the membrane surface of pre- and post-DMSO induced differentiated murine erythroleukemia (MEL) cells were examined and it was observed that the MG cation adsorbs onto the surface of the MEL cell, while neutral BCP does not.
Journal ArticleDOI
Towards quantification of myelin by solid-state MRI of the lipid matrix protons.
TL;DR: 3T data suggest that direct myelin imaging is feasible, but remaining challenging on clinical MR systems, and an adiabatic inversion‐recovery preparation was found to effectively suppress long‐T1 water signal in white matter, leaving short‐T2 myelin protons to be imaged.
Journal ArticleDOI
New insights into carbon-based and MXene anodes for Na and K-ion storage: A review
Zhensheng Hong,Zhensheng Hong,Hajar Maleki,Tim Ludwig,Yichao Zhen,Michael J. Wilhelm,Damin Lee,Kwang Ho Kim,Sanjay Mathur +8 more
TL;DR: In this paper, a review of 2D carbon materials and their architectures for Na and K-ion batteries through an in-depth analysis of structure-property interdependence and different electrochemical mechanisms supported by both experimental and theoretical data is discussed.
