Study on the synthesis of spin labeled poly(styrene-co-maleic acid)s and their segmental motion

open access: yesMagnetic Resonance Letters, 2022
Study of the segmental mobility of polymer chains is important when the polymer is used as drag reduction agents of crude oil. Electron spin resonance (ESR) spectroscopy can provide important information about segmental dynamics of polymer chains, which ...

Membrane chemical stability and seed longevity [PDF]

open access: yes, 2009
Here, we investigate the relationships between the chemical stability of the membrane surface and seed longevity. Dry embryos of long-lived tomato and short-lived onion seeds were labeled with 5-doxyl-stearic acid (5-DS).

Trityl Radicals: Spin Labels for Nanometer‐Distance Measurements [PDF]

open access: yes, 2012
Spin labelling with trityls: To gather information about the structure and dynamics of trityl radicals, spin-labelled polymers were measured with pulsed electron–electron double resonance (PELDOR) and double-quantum coherence (DQC).

Structural Refinement of Proteins by Restrained Molecular Dynamics Simulations with Non-interacting Molecular Fragments. [PDF]

open access: yesPLoS Computational Biology, 2015
The knowledge of multiple conformational states is a prerequisite to understand the function of membrane transport proteins. Unfortunately, the determination of detailed atomic structures for all these functionally important conformational states with ...

Erythrosin B as a New Photoswitchable Spin Label for Light-Induced Pulsed EPR Dipolar Spectroscopy

open access: yesMolecules, 2022
We present a new photoswitchable spin label for light-induced pulsed electron paramagnetic resonance dipolar spectroscopy (LiPDS), the photoexcited triplet state of erythrosin B (EB), which is ideal for biological applications.

EPR spectra of spin labels in lipid bilayers : II. Rotation of steroid spin probes [PDF]

open access: yes, 1974
The spin label method is used to investigate the nature of molecular motion in a liquid crystalline bilayer. The EPR spectra of different spin labels are simulated by means of perturbation theory.

Effects of a high-fat diet on superoxide anion generation and membrane fluidity in liver mitochondria in rats

open access: yesJournal of the International Society of Sports Nutrition, 2018
Background Obesity is a primary factor of lifestyle-related diseases, and the age of its onset has decreased. The reactive oxygen species (ROS), the superoxide anion, is generated in the mitochondrial electron transport chain and the damage it induces in
