In this study, the optical properties of glycated (HbA1c) and non-glycated (Hb) hemoglobin are compared using Surface-enhanced Raman spectroscopy (SERS), spectrofluorimetry, refractometry. Analysis spectral shift SERS spectra showed good discrimination between two hemoglobins indicating differences in their molecular structure. The fluorescence measured at excitation wavelengths 260, 270, 280 n...

The determination of glycohemoglobin [HbA1c, HbA1, or total glycohemoglobin (GHb)] has become an established procedure in the management of diabetes mellitus. Here, we describe the development of a simple, fluorescence, non-separation assay for the percentage of GHb (%GHb). The fluorescence of an eosin-boronic acid derivative when it was mixed with hemolysates of unwashed erythrocytes was quenc...

Measurement of glycohemoglobin has been recommended for the long-term assessment of glycemic control in diabetic patients. Because different analytical methods measure different glycohemoglobin species, it has been difficult to compare results between laboratories. Here we report 3 years of experience with calibration of an affinity chromatography method for measuring total glycohemoglobin (GHb...

Six months administration of bromocriptine mesylate significantly decreased glycated hemoglobin (HbA1c), fasting blood sugar, postprandial blood sugar, and weight of 22 Indian obese patients with type 2 diabetes mellitus with no serious adverse events. Therefore, the novel mechanism of action, efficacy and acceptable safety profile makes this drug an attractive option for treatment of obese typ...

Glycated proteins, particularly glycated hemoglobin A1c, are important markers for assessing the effectiveness of diabetes treatment. Convenient and reproducible assay systems based on the enzyme fructosyl amino acid oxidase (FAOD) have become attractive alternatives to conventional detection methods. We review the available FAOD-based assays for measurement of glycated proteins as well as the ...

[Purpose] This study determined the effects of passive static stretching on blood glucose levels in patients with type 2 diabetes. [Subjects] Fifteen patients (8 males and 7 females) with type 2 diabetes were recruited and randomly assigned to the control group or passive static stretching group. [Methods] Glycated hemoglobin was measured before and after the 8-week training period. [Results] G...
