BACKGROUND The impact of autologous stem cell transplantation (ASCT) in plasma cell myeloma patients on the frequency, quality, and timing of oligoclonal pattern in serum protein electrophoresis/immunofixation electrophoresis (SPEP/SIFE) and serum free light chain assay (SFLCA) was evaluated. METHODS Laboratory results and clinical data for 251 patients with plasma cell myeloma, who had SPEP/...

Iterated Hilbert transform (IHT) is a new method for multicomponent demodulation. The principle of IHT is introduced, and some of its properties are researched. Although the amplitudes of the demodulated components obtained by IHT are accurate, there are limitations in the direct estimation of instantaneous frequencies via the extracted phases, so a smoothed instantaneous frequency estimation (...

OBJECTIVES A growing body of literature has documented monoclonal proteins in children. Little is known about their associated diagnoses. METHODS We retrospectively evaluated all patients (aged 0-21 years) with abnormal findings on serum immunofixation electrophoresis (SIFE) from 2005 to 2011. We also documented the monoclonal immunoglobulin classes and light chain types involved and then cor...

OBJECTIVE Immunoglobulin free light chain (FLC) abnormalities are common in patients with monoclonal gammopathies and the kidneys are the most affected organs. Immunoassays that provide quantitative measurement of FLC in serum indicate monoclonal FLC production based on the presence of an abnormal FLC kappa:lambda (κ:λ) ratio. The aim of this study was to assess the utility of serum FLC measure...

This paper presents the use of the Particle Swarm Optimization for the identification of Jiles-Atherton model parameters. This approach is tested on two magnetic materials : NO 3% SiFe and NiFe 20-80. Results are compared with those obtained with a direct search method. Experimental validations are also presented.

CyberKnife is one of multiple modalities for stereotactic radiosurgery (SRS). Due to the nature of CyberKnife and the characteristics of SRS, dose evaluation of the CyberKnife procedure is critical. A radiophotoluminescent glass dosimeter was used to verify the dose accuracy for the CyberKnife procedure and validate a viable dose verification system for CyberKnife treatment. A radiophotolumines...

Abstract Background Serum immunofixation electrophoresis (SIFE) and serum free light chain (SFLC) assay are imperative investigations in diagnosis follow-up of multiple myeloma (MM). SFLC assays reported to have higher sensitivity than SIFE. However, discrepancies been between them. The current study was aimed at assessing concordance discordance SIFE results MM. Methods A total 450 observation...
