We report a potentiometric method for measuring the hemoglobin A1c (HbA1c, glycated hemoglobin) concentration, hemoglobin (Hb) concentration, and percent HbA1c (%HbA1c) in human blood hemolysate. The %HbA1c is important for diagnosis and management of diabetes mellitus. Alizarin red s (ARS) is used as a redox indicator. Phenylboronic acid (PBA) binds to both ARS and HbA1c via diol-boronic acid ...
Hydroxyapatite nanoparticle (nHAP) is increasingly being used to remediate soils and water polluted by metals and radionuclides. The transport and retention of Alizarin red S (ARS)-labeled nHAP were investigated in water-saturated granular media. Experiments were carried out over a range of ionic strength (I(c), 0-50mM NaCl) conditions in the presence of 10 mg L(-1) humic acid. The transport of...
Using the self-assembly of aromatic boronic acids with Alizarin Red S (ARS), we developed a new chemosensor for the selective detection of peroxynitrite. Phenylboronic acid (PBA), benzoboroxole (BBA) and 2-(N,N-dimethylaminomethyl)phenylboronic acid (NBA) were employed to bind with ARS to form the complex probes. In particular, the ARS-NBA system with a high binding affinity can preferably reac...
Although pulsed electromagnetic fields (PEMFs) have been used for treatments of nonunion bone fracture healing for more than three decades, the underlying cellular mechanism of bone formation promoted by PEMFs is still unclear. It has been observed that a series of parameters such as pulse shape and frequency should be carefully controlled to achieve effective treatments. In this article, the e...
OBJECTIVES Pyrophosphate arthropathy has been linked to diverse clinical subtypes. The two most common are: acute synovitis (pseudogout) and chronic pyrophosphate arthropathy ("pseudo-osteoarthritis"). We have conducted a study to examine whether these are overlapping syndromes. METHODS We reviewed all synovial fluid (SF) analyses performed in our laboratory from January 1988 to May 1997 to d...
To cite: Santiago T, Coutinho M, Malcata A, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013202183 DESCRIPTION An 80-year-old woman presented with a 1-month history of bilateral shoulder pain and swelling (figure 1). There was no history of any trauma. Physical examination showed limited and painful active and passive range of motion of the shoulders an...
