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...

The erythrocyte sedimentation rate (ESR) is still a widely used parameter for acute phase inflammation. Recently, new methods based on direct undiluted measurement of ESR in a standard EDTA tube have been developed. We evaluated the analytic performance of one of these new methods, the Ves-Matic Cube 200 (Diesse Diagnostica Senese, Siena, Italy), and compared it with several established Westerg...

Low-temperature magnetic properties of condensed matter system is investigated microscopically with high-frequency electron spin resonance (ESR). Experiments are carried out conventionally with a transmission method, but its sensitivity is not often sufficient to detect ESR signals of systems with small number of spins such as newly synthesized microcrystals. To attain better sensitivity, we fo...

The rate constants of nitroxide reduction by ascorbate ion were determined from a time-series measurement of ESR images, that is, ESR spatiotemporal images, which were measured with a rapid field scan L-band ESR-CT system. Two test tubes containing the phosphate buffer solutions of 3-carbamoyl-2,2,5,5-tetramethylpyrrolidin-l-yloxy (C-PROXYL) and ascorbate ion with different concentrations were ...

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 ...

In 50 patients with non-infected total hip arthroplasties (THA), 233 C-reactive protein (CRP) values were obtained over a three-year period. Six of these 50 patients occasionally had CRP values of over 20 mg/l. The erythrocyte sedimentation rate (ESR) and CRP concentration were measured in 23 patients with deep infections of THA before revision. In 11 patients the infections were caused by coag...

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...

The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) concentrations were studied in 101 elderly individuals (mean age 72 y) to determine their utility as diagnostic aids in subjects with underlying infection/inflammation. Whereas ESR and CRP were both significantly increased in patients with infection or inflammation, or both, analysis of variance indicated that those subjects ...

Objective: To examine the change in Procalcitonin (PCT) during the perioperative period of primary total hip replacement and to investigate the diagnostic value of PCT for prosthetic joint infection. Methods: Serum C-reactive protein (CRP) and Erythrocyte Sedimentation Rate (ESR) were measured and analysed in 36 patients with primary hip replacement both before the surgery and 1, 4, and 10 d af...
