Differentiation between bacterial infection and nonbacterial inflammation remains a diagnostic challenge. Vascular adhesion protein 1 (VAP-1) is a human endothelial protein whose cell surface expression is induced under inflammatory conditions, thus making it a highly promising target molecule for studying inflammatory processes in vivo. We hypothesized(More)
Antisense oligonucleotides may hybridise with high selectivity to mRNA sequences allowing monitoring of gene expression or inhibition of the manifestation of altered genes inducing diseases. As part of the development of positron emission tomography methods, 17-mer antisense phosphodiester (PO), phosphorothioate (PS) and 2'-O-methyl phosphodiester (OMe)(More)
INTRODUCTION Vascular adhesion protein-1 (VAP-1) is an infection/inflammation-inducible endothelial glycoprotein. Based on our previous studies, the most VAP-1-selective peptide (VAP-P1) was 1,4,7,10-tetraazacyclododecane-N',N'',N''',N-tetraacetic acid (DOTA)-conjugated, 68gallium (68Ga)-labeled (named [68Ga]DOTAVAP-P1) and evaluated preliminarily.

The aim of this study was to evaluate inflammation and tumour imaging with a vascular adhesion protein 1 (VAP-1) targeting peptide 68Ga-DOTAVAP-P1 in comparison with 18F-FDG. Rats with both subcutaneous human pancreatic adenocarcinoma xenografts and turpentine oil-induced acute sterile inflammation were evaluated by dynamic positron emission tomography(More)
UNLABELLED 1-(11)C-Methyl-4-piperidinyl n-butyrate ((11)C-MP4B) is a new radiopharmaceutical for the in vivo assessment of butyrylcholinesterase (BuChE) activity using PET. To quantify in vivo activity of BuChE with a kinetic model, investigators must determine the time course of radioactivity associated with unchanged (11)C-MP4B. We aimed at clarifying the(More)
The aim of the study was to compare 68Ga-chloride with 2-[18F]fluoro-2-deoxy-d-glucose (FDG) for the imaging of pancreatic xenografts. Rats with subcutaneous human pancreatic adenocarcinoma xenografts were evaluated in vivo by dynamic positron emission tomography (PET) and ex vivo by measuring radioactivity of excised tissues and by digital autoradiography(More)
UNLABELLED The biologic evaluation in living rats of (68)Ga-labeled oligonucleotides as imaging agents for PET is reported. METHODS (68)Ga, a positron-emitting radionuclide (half-life, 68 min), along with a macrocyclic chelating agent, 1,4,7,10-tetraazacyclododecane-N,N',N",N"'-tetraacetic acid (DOTA), was used for labeling of antisense oligonucleotides(More)
