Visualization and Quantification of Brown and Beige Adipose Tissues in Mice using [18F]FDG Micro-PET/MR Imaging

Abstract:
Acclimation temperature (28 or 5 degrees C) modifies acetoacetate (AA) and beta-hydroxybutyrate (BOH) levels in blood and liver. In the fed state AA and BOH levels were increased in blood and liver of 5 degrees C adapted rats. In the fasting state (24 or 48 hr) an antiketotic action of cold acclimation was observed. It was found to be more pronounced with high fat diet. These effects were more marked in the blood than in the liver. The variations in ketonemia are discussed with relation to the role of liver in cold adapted rats.
