Fragile X Mental Retardation Protein and Cerebral Expression of Metabotropic Glutamate Receptor Subtype 5 in Men with Fragile X Syndrome: A Pilot Study

Brain Sciences, 2022
Multiple lines of evidence suggest that a deficiency of Fragile X Mental Retardation Protein (FMRP) mediates dysfunction of the metabotropic glutamate receptor subtype 5 (mGluR5) in the pathogenesis of fragile X syndrome (FXS), the most commonly known ...

Estimation of activity of administered 18F-fluorodeoxyglucose by measurement of the dose equivalent rate on the right temporal region of the head

EJNMMI Physics, 2016
Background Positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) is now a routine procedure for the management of cancer patients. Intravenous administration of FDG is sometimes halted due to troubles. In such cases, estimations of the FDG

Cardiac Positron Emission Tomography

Journal of the American College of Cardiology, 2009
Positron emission tomography (PET) is a powerful, quantitative imaging modality that has been used for decades to noninvasively investigate cardiovascular biology and physiology. Due to limited availability, methodologic complexity, and high costs, it has long been seen as a research tool and as a reference method for validation of other diagnostic ...

Development of an automated method for in-house production of sodium 18F-fluoride for injection: process validation as a step toward routine clinical application

EJNMMI Radiopharmacy and Chemistry
Background Sodium 18F-fluoride for injection can be easily cyclotron-produced and purified, as a simple inorganic salt, by adsorption/desorption onto an anion-exchange cartridge and then dispensed for clinical use.
