Journal ArticleDOI
The gamut of alkoxy radicals
TL;DR: In this article, it was shown that various radicals exhibiting diverse ESR and ENDOR spectral characteristics are nonetheless a closely related family of alkoxy radicals, and the relationship was established by correlating the g tensor with crystal structure.
Journal ArticleDOI
Hyperfine couplings in primary radiation products
TL;DR: In this paper, the characteristics of proton couplings in primary radiation products in irradiated protein and nucleic acid constituents are described, and a close correlation between σ proton coupling tensors in conjugated oxidation and reduction products and principal axes derived from crystal structure is demonstrated.
Journal ArticleDOI
Covalently Linked Tandem Lesions in DNA
Helen B. Patrzyc,Jean B. Dawidzik,Edwin E. Budzinski,Harold G. Freund,John Wilton,Harold C. Box +5 more
TL;DR: This work comprehensively survey X-irradiated DNA for covalently linked tandem lesions to generate highly characteristic liquid chromotography-tandem mass spectrometry (LC-MS/MS) elution profiles.
Journal ArticleDOI
Radiation-Induced Formation of 3,4-Dihydroxyphenylalanine in Tyrosine-Containing Peptides and Proteins as a Function of X-Irradiation Dose
TL;DR: Sensitive analysis of protein-bound DOPA will be useful to study amplification of the radical-damaging event, and most standard amino acid analysis techniques are limited to detect normal residues of protein.
Journal ArticleDOI
Flying‐Spot Microscope Adapted for Quantitative Measurements
Harold C. Box,Harold G. Freund +1 more
TL;DR: Certain quantitative cytological measurements can be made by the addition of relatively simple components to a television flying‐spot microscope, which avoids ``distributional errors'' inherent in conventional microphotometry measurements.
