R ECENTLY a new reagent was proposed for the determination of cholesterol (1, 2). This reagent was purported to be saturated ferrous sulfate in glacial acetic acid. Since it has been reported that ferrous sulfate is qualitatively insoluble in anhydrous acetic acid (3, 4) and that ferrous iron is “subject to pronounced air oxidation in glacial acetic acid” (5), it was felt that several factors s...

Due to the unique optical properties like high brightness and narrow emission bands of Quantum dots, it is used as simple fluorescence materials in bio-imaging, immunoassays, microarrays, and other applications. To easy invistigate cell lines that overexpressed somtostatin receptors, somatostatin (SST) was conjugated with Quantum dots carrying PEG amine (Qdots-PEG-NH2). The conjugation of SST t...

A new selective reagent was used for simultaneous determination of mercury and palladium in real samples with their different kinetic spectrophotometric properties. The method is based on the difference in the rate of the oxidation reaction of the recently synthesized reagent, nitro benzoyl diphenylmethylen phosphorane (N-BDMP), with Hg2+ and Pd2+. The kinetic profiles were monitored and record...

The article entitled "Evaluation of the Analytical Performance of the Coulometry-Based Optium Omega Blood Glucose Meter", by Solnica and colleagues in this issue of Journal of Diabetes Science and Technology demonstrates that the Optium Omega blood glucose meter meets the analytical requirements for glucose meter performance and it is stated that the results are clinically useful. The authors s...

A total of 5,174 Japanese men were included in a cross-sectional study to examine the relationship between the glycated hemoglobin (HbA1C) level and the prevalence of proteinuria as determined using a reagent strip. The prevalence of proteinuria rose significantly at HbA1C levels above 5.9%, whereas no relationship was observed at HbA1C levels below 5.9%. Multiple logistic regression analysis s...

We examined the analytical performance of eight compact systems for measuring total cholesterol: AccuMeter, Cobas Ready, Discovery f2, DT60, L-D-X, Reflotron, QCA, and Vision. We determined average bias at two decision levels, the mean absolute bias, and the percentage of results differing from the comparison method results by > 8.9% allowable total error limit for multiple reagent lots. Averag...
