The electron scattering region (ESR) is one of important ingredients in Seyfert nuclei because it makes possible to observe the hidden broad line region (hereafter HBLR) in some type 2 Seyfert nuclei (hereafter S2s). However, little is known about its physical and geometrical properties. Using the number ratio of S2s with and without HBLR, we investigate statistically where the ESR is in Seyfer...

OBJECTIVES To assess inflammatory serum markers including serum proinflammatory cytokines, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) according to the clinical inflammatory activity of patients with hidradenitis suppurativa (HS). PATIENTS AND METHODS Seventy-four patients with HS were studied based on the Hidradenitis Suppurativa-Physician Global Assessment (HS-PGA) sc...

Electron spin resonance (ESR) spectroscopy's affinity for detecting paramagnetic free radicals, or spins, has been increasingly employed to examine a large variety of biochemical interactions. Such paramagnetic species are broadly found in nature and can be intrinsic (defects in solid-state materials systems, electron/hole pairs, stable radicals in proteins) or, more often, purposefully introdu...

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)...

INTRODUCTION Our aim was to investigate the diagnostic accuracy of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) in patients with acute scrotum. MATERIALS AND METHODS One hundred and twenty patients with acute scrotum were evaluated and divided into 3 groups: 46 with acute epididymitis (group 1), 23 with spermatic cord torsion (group 2), and 51 with other noninflammatory c...

ESR methods. The bias between TEST-1 and the manual Westergren method was 22.7 mm/h (agreement limits, 233 to 8 mm/h). Concerning reproducibility, the mean interassay CV was 7.9%. The ESR values for samples stored for up to 24 h were, on average, 4% lower than the initial values. However, after storage for 48 h, ESR values were, on average, 24% lower than the initial values. Therefore, we consi...

We have developed a high-field and high-frequency ESR system using a commercially available magnetometer equipped with the superconducting quantum interference device (SQUID). This is magnetization detection type ESR and ESR is observed as a change of the magnetization at the resonance condition under irradiation of the electromagnetic wave. The frequency range is from 70 to 315 GHz and the max...

A new way to study the action of cyclodextrin was developed to quantify the damage caused on cell membrane and lipid bilayer. The Electron Spin Resonance (ESR) spectroscopy was used to study the action of Randomly methylated-beta-cyclodextrin (Rameb) on living cells (HCT-116). The relative anisotropy observed in ESR spectrum of nitroxide spin probe (5-DSA and cholestane) is directly related to ...

BACKGROUND The erythrocyte sedimentation rate (ESR) is a simple and inexpensive laboratory test, which is widespread in clinical practice, for assessing the inflammatory or acute response. This work addresses the theoretical and experimental investigation of sedimentation a single and multiple particles in homogeneous and heterogeneous (multiphase) medium, as it relates to their internal struct...

BACKGROUND The erythrocyte sedimentation rate (ESR) is a simple and inexpensive laboratory test. It is commonly used to assess the acute phase response. METHODS A review of the recent literature was done to evaluate the role of the ESR and its importance in different clinical conditions both inflammatory and noninflammatory. RESULTS Despite the critical role cytokines have in inflammatory c...
