UNLABELLED Imaging of serotonin transporter (SERT) in the central nervous system may provide an important tool to evaluate some psychiatric disorders. Recently, a novel (123)I-labeled radiotracer, 2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine ((123)I-ADAM), has been developed that exhibited a high selectivity for SERT. The aim of this study was to characterize the biodistribution ...

UNLABELLED Chronic renal failure (CRF) patients on dialysis frequently show reduced heart rate variability (HRV), which has been reported to be corrected by renal transplantation. Recently, (123)I-metaiodobenzylguanidine ((123)I-MIBG) scintigraphy has been used to evaluate cardiac sympathetic innervation, and uremic patients often show marked abnormalities of cardiac (123)I-MIBG uptake. We inve...

Platinum rhodamine 123 [Pt(Rh-123)2] was synthesized in an effort to produce a new drug which would have the selective uptake into carcinoma cells of Rh-123 and the alkylating and radiosensitizing properties of the chloroplatinum moiety. Because both Rh-123 and cis-diamminedichloroplatinum(II) (CDDP) have been shown to become more cytotoxic at elevated temperatures, we tested the interactions b...

We exploit Krattenthaler’s bijection between 123-avoiding permutations and Dyck paths to determine the Eulerian distribution over the set Sn(123) of 123-avoiding permutations in Sn. In particular, we show that the descents of a permutation correspond to valleys and triple ascents of the associated Dyck path. We get the Eulerian numbers of Sn(123) by studying the joint distribution of these two ...

PURPOSE To evaluate the potential utility of (123)I-metaiodobenzylguanine ((123)I-MIBG) scintigraphy and (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) for the detection of primary and metastatic lesions in pediatric neuroblastoma (NBL) patients, and to determine whether (18)F-FDG PET is as beneficial as (123)I-MIBG imaging. METHODS We selected 8 NBL patients with sig...

INTRODUCTION (123)I-N-isopropyl-p-iodoamphetamine ((123)I-IMP) is metabolized and converted to (123)I-p-iodoamphetamine ((123)I-PIA) by CYP2C19 in humans. Since variations in (123)I-PIA levels reflect variations in CYP2C19 activity, CYP2C19 activity can be estimated by quantitative analysis of (123)I-PIA levels. Thus, (123)I-IMP administration can provide diagnostic information not only regardi...

UNLABELLED (123)I-ADAM (2-([2-([dimethylamino]methyl)phenyl]thio)-5-(123)I-iodophenylamine) has been recently proposed as a new serotonin transporter (SERT) ligand for SPECT. The objective of this study was to characterize (123)I-ADAM in healthy volunteers. (123)I-ADAM distribution in the normal brain, pseudoequilibrium interval after a single injection, normal specific uptake values, and long-...
