OBJECTIVES In line with previous research on the development of conjugated bisphosphonate ligands as new bone-avid agents, in this study, DOTA-conjugated alendronate (DOTA-ALN) was synthesized and evaluated after labeling with gallium-68 ((68)Ga). METHODS DOTA-ALN was synthesized and characterized, followed by (68)Ga-DOTA-ALN preparation, using DOTA-ALN and (68)GaCl3 (pH: 4-5) at 92-95° C for...
BACKGROUND In the present study, we sought to evaluate the feasibility of targeting vascular adhesion protein-1 (VAP-1) by positron emission tomography (PET) for the longitudinal quantitative assessment of Borrelia burgdorferi infection-induced inflammation in mice. METHODS Mice with B. burgdorferi infection-induced arthritis were studied. During a 7-week follow-up period, the progression of ...
BACKGROUND Absorbed doses for α-emitters are different from those for β-emitters, as the high linear energy transfer (LET) nature of α-particles results in a very dense energy deposition over a relatively short path length near the point of emission. This highly localized and therefore high energy deposition can lead to enhanced cell-killing effects at absorbed doses that are non-lethal in low-...
High density lipoproteins (HDLs; d = 1.063 - 1.21 g/ml) were isolated by ultracentrifugation and radiolabeled with 111In. The in vitro binding onto platelets from healthy volunteers (n = 15) and patients (n = 36) with heterozygous familial hypercholesterolemia (FH) was investigated. Binding was saturable and indicated high-affinity binding sites, which bound 1,882 +/- 361 ng protein of 111In-HD...
To establish a rational molecular design for bisphosphonate (BP)-modified proteins for efficient bone targeting, a pharmacokinetic study was performed using a series of alendronate (ALN), a nitrogen-containing BP, modified proteins with various molecular weights and varying degrees of modification. Four proteins with different molecular weight-yeast glutathione reductase (GR; MW: 112,000 Da), b...
BACKGROUND Safety is a primary concern with contrast agents used for MRI. If precautions could be taken before the repeated administration of gadolinium-based contrast media, then the awareness and management of adverse reactions would be more efficient. OBJECTIVES To assess the safety and efficacy of gadoterate meglumine (Gd-DOTA) [Magnescope® in Japan, Dotarem® in other countries], a gadoli...
UNLABELLED Strong overexpression of glucagonlike peptide-1 (GLP-1) receptors in human insulinoma provides an attractive target for imaging. The first clinical trials demonstrated that GLP-1 receptor SPECT/CT using [Lys(40)(Ahx [6-aminohexanoic acid]-DOTA-(111)In)NH(2)]-exendin-4 can localize hardly detectable insulinomas. However, [Lys(40)(Ahx-DOTA-(111)In)NH(2)]-exendin-4 imaging has drawbacks...
UNLABELLED Biodistribution and dosimetry of 88Y (and equimolar 90Y) Janus-dodecanetetraacetic acid (DOTA) were performed using a three-step pretargeting protocol in BALB/c mice bearing mouse mammary adenocarcinoma (KHJJ) implants. Pretargeting was performed with mouse monoclonal antibody (mAb) 2D12.5 specific for yttrium-DOTA, and the chase was Y-DOTA-human transferrin conjugate. In this articl...
BACKGROUND AND PURPOSE Vascular endothelial growth factor (VEGF) and VEGF receptors (VEGFRs) play important roles during neurovascular repair after stroke. In this study, we imaged VEGFR expression with positron emission tomography (PET) to noninvasively analyze poststroke angiogenesis. METHODS Female Sprague-Dawley rats after distal middle cerebral artery occlusion surgery were subjected to ...
