UNLABELLED Mesenchymal stem cells (MSCs) are a promising cell line for the treatment of ischemic heart disease. To evaluate the success of their transplantation into living animals, noninvasive imaging techniques that are able to track the distribution and fate of those cells would be useful. The aim of this study was to investigate the feasibility of(More)
Fluorine-18 fluoroethylflumazenil ([18F]FEF) is a tracer for central benzodiazepine (BZ) receptors which is proposed as an alternative to carbon-11 flumazenil for in vivo imaging using positron emission tomography (PET) in humans. In this study, [18F]FEF kinetic data were acquired using a 60-min two-injection protocol on three normal subjects and two(More)
The early E ≤ 511 keV gamma–ray emission from novae depends critically on the 18 F(p,α) 15 O reaction. Unfortunately the reaction rate of the 18 F(p,α) 15 O reaction is still largely uncertain due to the unknown strengths of low–lying proton resonances near the 18 F+p threshold which play an important role in the nova temperature regime. We report here our(More)
