INTRODUCTION Recently a new somatostatin analogue labelled with (99m)Tc ((99m)Tc-HYNIC-TOC) has been synthetized. Aim of this study was to evaluate the utility of (99m)Tc-HYNIC-TOC in the radionuclide imaging in patients with medullary thyroid carcinoma (MTC). MATERIAL AND METHODS 30 patients with MTC aged 22-83 years in different stages of the disease were investigated. In 6 patients (group ...

European Association (EANM), 1985, nonprofit medical association facilitate communication among individuals medicine pursuing clinical academic excellence. Memb...

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...

© 2008 Elsevier. All rights reserved. The pentavalent Tc-99m dimercaptosuccinic acid (Tc99m (V) DMSA, Tc(V)-DMSA) radiotracer has become more widely used. The accumulation of Tc(V)-DMSA in tumors was first reported in 1981 [1], and this tracer has subsequently been shown to localize in a variety of tumors [2,3]. Tc(V)-DMSA has also been used to depict abscesses and other inflammatory lesions [4...

A 5-year-old girl was admitted with fever and diurnal enuresis. In her medical history, she had numerous recurrent urinary tract infections; however, she was not evaluated with radiological methods. Urinalysis revealed pyuria and the urine culture grew >100 000 Escherichia coli. Urinary ultrasonography showed that the left kidney was smaller than the right kidney, with a longitudinal kidney dia...

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...

We present a method for the purification of the 45 residue long leader peptide of Escherichia coli dimethyl sulfoxide reductase subunit A (DmsA(L)), a substrate of the twin arginine translocase, by co-expressing the leader peptide with its specific chaperone protein, DmsD. The peptide can be isolated from the soluble DmsA(L)/DmsD complex or conveniently from the lysate pellet fraction. The reco...

BACKGROUND The reliable method for determination of identity and radiochemical purity (RCP) is of great importance in radiopharmaceutical development. This is especially relevant when more than one form of radiometal/ligand complex can be formed during radiolabelling, such as complexes of 99mTc or 188Re with meso-2,3-dimercaptosuccinic acid (DMSA), where depending on the pH, metal can occur eit...

BACKGROUND Acute pyelonephritis often leaves children with permanent renal scarring. AIMS To compare the prevalence of scarring following initial treatment with antibiotics administered intravenously for 10 or three days. METHODS In a prospective two centre trial, 220 patients aged 3 months to 16 years with positive urine culture and acute renal lesions on initial DMSA scintigraphy, were ra...
