Recent applications of ESR, NMR and ENDOR to the following investigations are briefly reviewed : motional effects of point defects, influence of structural phase transitions on defects, self diffusion, dislocation motion, structure of low symmetry defects, excited states of defects. The application of ENDOR-induced ESR to solid state defects is briefly described. It allows the analysis of super...

Spectral analysis considers the problem of determining (the art of recovering) the spectral content (i.e., the distribution of power over frequency) of a stationary time series from a finite set of measurements, by means of either nonparametric or parametric techniques. This paper introduces the spectral analysis problem, motivates the definition of power spectral density functions, and reviews...

INTRODUCTION Evidences of biologics-free disease control after discontinuing adalimumab (ADA) in rheumatoid arthritis (RA) patients in clinical practice have not been sufficiently investigated. Purpose of this study is to investigate whether disease activity score 28 (DAS28)- erythrocyte sedimentation rate (ESR) remission was preserved after discontinuation of ADA in patients with RA. METHODS...

OBJECTIVE C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are common measures of systemic inflammation. Our goal was to identify clinical factors associated with CRP/ESR discordance. METHODS We identified patients with ESR and CRP results at our academic hospital over six months. We matched individuals with discordant results (one measure in highest tertile, other in lowest)...

Given the specific melanin-associated paramagnetic features, the Electron Spin Resonance (ESR, called also Electron Paramagnetic Resonance, EPR) analysis has been proposed as a potential tool for non-invasive melanoma diagnosis. However, studies comparing human melanoma tissues to the most appropriate physiological counterpart (nevi) have not been performed, and ESR direct correlation with mela...

A review of 80 patients with the polymyalgia rheumatica/giant cell arteritis (PMR/GCA) syndrome has revealed that the erythrocyte sedimentation rate (ESR) is normal in 22.5% of cases at presentation. Too much reliance on the ESR as a screening test led to delay in diagnosis in 10 patients. Serious complications occurred in 4 patients with a normal or minimally raised ESR. Analysis of follow-up ...

Comparison of clinically assessed activity of disease with 112 paired readings of the erythrocyte sedimentation rate (ESR) and the plasma viscosity (PV) in 23 patients with polymyalgia rheumatica (PMR) showed the following. (1) A correlation between ESR and PV in both sexes, reaching the significance obtained in a comparison group of patients with rheumatoid arthritis (RA) (109 paired readings)...
