BACKGROUND Abnormal Dimercaptosuccinic acid (DMSA) renal scintigraphy performed six months after an acute pyelonephritis (AP) is generally interpreted as scarring. AIM To perform a follow up of childhood patients showing scintigraphic renal lesions during the acute phase of pyelonephritis (within 7 days from the beginning of fever). MATERIAL AND METHODS A scintigraphic control was carried o...
Twenty-five patients with solitary cold thyroid nodules (SCN) were studied by fine needle aspiration (FNA) cytology, radionuclide perfusion scanning (RPS) and pentavalent technetium dimercaptosuccinic acid (99m Tc DMSA) scanning, with an aim to distinguish neoplastic from non-neoplastic nodules. All the patients were operated upon and the nodules were subjected to histopathological examination....
The effects of 2,3-dimercaptosuccinic acid (DMSA) and 2,3-dimercaptopropane-1-sulfonic acid, Na salt (DMPS) on arsenic excretion in arsenic poisoning were studied using ICR mice. One group of mice was given arsenic trioxide (5 mg As/kg, s.c.) and another two groups were given DMSA or DMPS (100 mg/kg, i.p.) immediately after administration of the arsenic (5 mg/kg, s.c.). Arsenic excretion in uri...
BACKGROUND Rupture of an atherosclerotic plaque is the primary cause of acute cardiovascular and cerebrovascular syndromes. Early and non-invasive detection of vulnerable atherosclerotic plaques (VP) would be significant in preventing some aspects of these syndromes. As a new contrast agent, dimercaptosuccinic acid (DMSA) modified ultra-small super paramagnetic iron oxide (USPIO) was synthesize...
We report a high yielding synthesis of truly monodisperse, thiolate-protected silver clusters via a rationally designed approach. The cluster composition was determined by electrospray ionization (ESI) mass spectrometry to be Ag(7)(DMSA)(4), where DMSA represents meso-2,3-dimercaptosuccinic acid. The Ag(7) thiolate clusters exhibit distinct optical properties. The approach developed in this wor...
A liposome system that can detect and detoxify mercury in aqueous solution is demonstrated. The system consists of 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine and 20% PEG-PE (PEG MW 2000 Da) that forms liposome, which encapsulates self-quenching fluorescein for detection, and chelating agent meso-2,3-dimercaptosuccinic acid (meso-DMSA) for chelating detoxification through Hg(2+)-responsive re...
Two groups of 12 human volunteers, who had been treated with colloidal bismuth subcitrate, because of Helicobacter pylori-associated gastritis, participated in the study. The patients received a single dose of meso-2,3-dimercaptosuccinic acid (DMSA) or D,L-2,3-dimercaptopropane-1-sulfonic acid (DMPS) at a dose of 30 mg kg-1 in a randomized single blind study. In contrast to DMPS, increasing con...
We present a patient with Fanconi syndrome who demonstrated poor renal uptake of 99mTc-DMSA and high urinary concentration of the tracer. A 99mTc-DTPA scan was normal and the creatinine clearance only minimally decreased. These findings suggest that 99mTc-DMSA may be accumulated in the kidney by glomerular filtration and subsequent tubular reabsorption, with the nonabsorbed fraction appearing i...
c a anagement of vesicoureteral reflux (VUR) involves as uch controversy as management of prostate cancer. magine if there was an easily available serum or radioraphic test that could definitively determine whether a an with prostate cancer would have any local spread of he disease, and whether it would ever cause any sympoms. Would not that test replace prostate-specific antien (PSA) or any ot...
The twin-arginine translocase (Tat) system is used for the targeting and translocation of folded proteins across the cell membrane of most bacteria. Substrates of this system contain a conserved "twin-arginine" (RR) motif within their signal/leader peptide sequence. Many Tat substrates have their own system-specific chaperone called redox enzyme maturation proteins (REMPs). Here, we study the b...
