AIM The aim of this study was to assess the degree of alterations of renal function by using 99m-technetium dimercaptosuccinic acid ((99m)Tc-DMSA) and 99m-technetium diethylenetriaminepentaacetic acid ((99m)Tc-DTPA) scintigraphy in spinal cord injury (SCI) patients. MATERIAL AND METHODS Twenty-two consecutive SCI (15 paraplegic and 7 tetraplegic) patients (mean age: 49.1±13.4 years) who had n...

Technetium-99m labeling of antibodies has been suboptimal because of low affinity adventitious binding, nonspecific labeling, and loss of immunoreactivity. The diamide dithiolate ligand system (N2S2) forms highly stable, well-defined tetradentate complexes with Tc(V). Antibodies and their fragments have been labeled by conjugation of preformed 99mTc-4,5-bis(thioacetamido)pentanoate active ester...

In this study an attempt has been made to examine the efficacy of meso-2,3-dimercaptosuccinic acid (DMSA) using galactosylated liposomes as carriers for mobilization of cadmium from the body of mice preexposed to cadmium chloride (0.005 mmoles/kg intraperitoneally daily for 4 days). Cadmium-exposed mice after a rest period of 8 weeks were administered DMSA intravenously, two injections 15 micro...

Tc-99m dimercaptosuccinic acid (DMSA) is used as a renal cortical imaging agent to detect parenchymal abnormalities especially in children. Kidney uptake of DMSA provides an index for evaluation of a functional tubular mass, which depends on the renal blood flow and proximal tubular cell membrane transport function. We here report a boy with renal tubular acidosis, which has noticeably reduced ...

The system specific chaperone DmsD plays a role in the maturation of the catalytic subunit of dimethyl sulfoxide (DMSO) reductase, DmsA. Pre-DmsA contains a 45-amino acid twin-arginine leader peptide that is important for targeting and translocation of folded and cofactor-loaded DmsA by the twin-arginine translocase. DmsD has previously been shown to interact with the complete twin-arginine lea...
