Using cyclodextrins to encapsulate oxygen-centered and carbon-centered radical adducts: the case of DMPO, PBN, and MNP spin traps.
J. Phys. Chem. A 114(21) , 6217-25, (2010) We present electron spin resonance (ESR) experiments that describe the interaction of beta-cyclodextrin (beta-CD) with spin adducts of three spin traps: 5,5-dimethyl-1-pyrroline N-oxide (DMPO), N-tert-butyl-alpha-phenylnitrone (PBN), and 2-methyl-2-nitrosopro... |

Stratum corneum intercellular lipid as compared to erythrocyte ghosts: an ESR study of thermotropic behavior and nitroxide reduction. Electron Spin Resonance.
Physiol. Chem. Phys. Med. NMR 27(1) , 63-72, (1995) Intercellular membranes of Stratum Corneum and erythrocyte ghosts were studied through partition of Tempo nitroxide spin label. Stratum Corneum presents a phase transition-monitored by the spin label at 58 degrees C--that is in agreement with data obtained th... |

Guest inclusion in cucurbiturils studied by ESR and DFT: the case of nitroxide radicals and spin adducts of DMPO and MNP.
J. Phys. Chem. A 116(33) , 8475-83, (2012) We present an ESR and DFT study of the interaction of cucurbiturils CB[6], CB[7], and CB[8] with di-tert-butyl nitroxide ((CH(3))(3)C)(2)NO (DTBN) and with spin adducts of 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) and 2-methyl-2-nitrosopropane (MNP). The primar... |

Model membrane partition ESR study in the presence of alpha-tocopherol by a new spin probe.
Biosci. Rep. 9(4) , 489-95, (1989) The effect of alpha-tocopherol (alpha T) on partitioning and fluidity changes occurring in phospholipid liposomes have been investigated by monitoring the X-band ESR spectrum of the high resolution amphiphilic spin probe perdeutero-di-t-butyl nitroxide (PDDTB... |

Calorimetric and electron spin resonance examination of lipid phase transitions in human stratum corneum: molecular basis for normal cohesion and abnormal desquamation in recessive X-linked ichthyosis.
J. Invest. Dermatol. 91(5) , 499-505, (1988) Lipids appear to play a critical role as regulators of stratum corneum desquamation. In this study, we observed discrete lipid phase transitions at physiologic temperatures in both normal human scale (NHS) and in lipid extracts of NHS by differential scanning... |

Identification and quantification of regioisomeric cholesteryl linoleate hydroperoxides in oxidized human low density lipoprotein and high density lipoprotein.
Chem. Res. Toxicol. 9(4) , 737-44, (1996) Oxidation of human LDL is implicated as an initiator of atherosclerosis. Isolated low density lipoprotein (LDL) and high density lipoprotein (HDL2) were exposed to aqueous radicals generated from the thermolabile azo compound 2,2'-azobis(2-amidinopropane) dih... |

Electron paramagnetic resonance (EPR) imaging in skin: biophysical and biochemical microscopy.
J. Invest. Dermatol. 98(5) , 713-9, (1992) Electron paramagnetic resonance (EPR) is a spectroscopic technique that allows detection of paramagnetic compounds, e.g., free radicals, in skin, and is used for measuring skin membrane fluidity and polarity. EPR imaging is concerned with spatially resolved E... |

Calculation of solvent shifts on electronic g-tensors with the conductor-like screening model (COSMO) and its self-consistent generalization to real solvents (direct COSMO-RS).
J. Phys. Chem. A 110(6) , 2235-45, (2006) The conductor-like screening model (COSMO) was used to investigate the solvent influence on electronic g-values of organic radicals. The previously studied diphenyl nitric oxide and di-tert-butyl nitric oxide radicals were taken as test cases. The calculation... |

Amyloid beta peptides do not form peptide-derived free radicals spontaneously, but can enhance metal-catalyzed oxidation of hydroxylamines to nitroxides.
J. Biol. Chem. 274(14) , 9392-9, (1999) Amyloid beta (Abeta) peptides play an important role in the pathogenesis of Alzheimer's disease. Free radical generation by Abeta peptides was suggested to be a key mechanism of their neurotoxicity. Reports that neurotoxic free radicals derived from Abeta-(1-... |

Experimental and theoretical studies of magnetic exchange in silole-bridged diradicals.
Chemistry 12(21) , 5547-62, (2006) Five bis(tert-butylnitroxide) diradicals connected by a silole (7 a-d) or a thiophene (12) ring as a coupler were studied. Compound 12 crystallizes in the orthorhombic space group Pna2(1) with a = 20.752(5), b = 5.826(5), and c = 34.309(5) A. X-ray crystal st... |
