Low-intensity fluorescence of rhodamine-123 (Rh-123) discriminates a quiescent hematopoietic stem cell (HSC) population in mouse bone marrow, which provides stable, long-term hematopoiesis after transplantation. Rh-123 labels mitochondria with increasing intensity proportional to cellular activation, however the intensity of staining also correlates with the multidrug resistance (MDR) phenotype...

UNLABELLED The purpose of this study was to compare the diagnostic utility of (123)I-metaiodobenzylguanidine ((123)I-MIBG) scintigraphy and (18)F-FDG PET in neuroblastoma. METHODS A total of 113 paired (123)I-MIBG and (18)F-FDG PET scans in 60 patients with neuroblastoma were retrospectively reviewed. Paired scans were acquired within 14 days of each other. RESULTS For stage 1 and 2 neurobl...

BACKGROUND SZ-123, a murine monoclonal antibody that targets the human von Willebrand factor (VWF) A3 domain and blocks the binding of collagen, is a powerful antithrombotic. In a Rhesus monkey model of thrombosis, SZ-123 had no side effects, such as bleeding or thrombocytopenia. METHODS The mouse/human chimeric version of SZ-123, MHCSZ-123, was developed and maintained inhibitory capacities ...

A decreased cardiac (123)I-metaiodobenzylguanidine ((123)I-MIBG) uptake has been used as a powerful tool to identify Lewy body disease, such as idiopathic parkinson's disease (IPD). We performed cardiac (123)I-MIBG scintigraphy in patient with autosomal recessive juvenile parkinsonism (ARJP) with parkin gene mutation (PARK2). The findings showed normal cardiac (123)I-MIBG uptake. Therefore, alt...

Rationale: The antiangiogenic activity of rPAI-123, a truncated plasminogen activator inhibitor-1 (PAI-1) protein, induces vasa vasorum collapse and significantly reduces plaque area and plaque cholesterol in hypercholesterolemic low-density lipoprotein receptor–deficient/apolipoprotein B48–deficient mice. Objective: The objective of this study was to examine rPAI-123–stimulated mechanisms that...

Prostate-specific membrane antigen (PSMA) is expressed in normal human prostate epithelium and is highly up-regulated in prostate cancer. We previously reported a series of novel small molecule inhibitors targeting PSMA. Two compounds, MIP-1072, (S)-2-(3-((S)-1-carboxy-5-(4-iodobenzylamino)pentyl)ureido)pentanedioic acid, and MIP-1095, (S)-2-(3-((S)-1carboxy-5-(3-(4-iodophenyl)ureido)pentyl)ure...

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 ...
