Insights into disseminated MS brain pathology with multimodal diffusion tensor and PET imaging
<div>Objective To evaluate in vivo the co-occurrence of microglial activation and microstructural white matter (WM) damage in the MS brain and to examine their association with clinical disability.</div><div>Methods 18-kDa ...
Global and segmental absolute stress myocardial blood flow in prediction of cardiac events: [15O] water positron emission tomography study
Purpose We evaluated the value of reduced global and segmental absolute stress myocardial blood flow (sMBF) quantified by [O-15] water positron emission tomography (PET) for predicting cardiac events in patients with ...
18-kDa translocator protein ligand 18F-FEMPA: Biodistribution and uptake into atherosclerotic plaques in mice
<p>18F-FEMPA shows rapid blood clearance and uptake in the mouse aorta. Uptake in atherosclerotic plaques correlated with the amount of macrophages, but did not exceed that in the normal vessel wall.<br /></p>
Adventures in radiosynthesis of clinical grade [68Ga]Ga-DOTA-Siglec-9
We finally managed to establish a protocol for generating Good Manufacturing Practice (GMP)-grade gallium-68-labelled 1,4,7,0-tetraazacyclododecane-1,4,7,10-tetraacetic acid conjugated sialic acid-binding immunoglobulin-like ...
Insulin-stimulated glucose uptake in skeletal muscle, adipose tissue and liver: A positron emission tomography study
<p>Objective: Insulin resistance is reflected by the rates of reduced glucose uptake (GU) into the key insulin-sensitive tissues, skeletal muscle, liver and adipose tissue. It is unclear whether insulin resistance occurs ...
HPLC and TLC methods for analysis of [F-18]FDG and its metabolites from biological samples
The most used positron emission tomography (PET) tracer, 2-[F-18]fluoro-2-deoxy-o-glucose ([F-18]FDG), is a glucose analogue that is used to measure tissue glucose consumption. Traditionally, the Sokoloff model is the basis ...
Evaluation of image quality with four positron emitters and three preclinical PET/CT systems
Background We investigated the image quality of C-11, Ga-68, F-18 and Zr-89, which have different positron fractions, physical half-lifes and positron ranges. Three small animal positron emission tomography/computed ...
Sprint interval training decreases left-ventricular glucose uptake compared to moderate-intensity continuous training in subjects with type 2 diabetes or prediabetes
Type 2 diabetes mellitus (T2DM) is associated with reduced myocardial glucose uptake (GU) and increased free fatty acid uptake (FFAU). Sprint interval training (SIT) improves physical exercise capacity and metabolic ...
Comparative effects of dexmedetomidine, propofol, sevoflurane, and S-ketamine on regional cerebral glucose metabolism in humans: a positron emission tomography study
<p>Introduction: The highly selective alpha(2)-agonist dexmedetomidine has become a popular sedative for neurointensive care patients. However, earlier studies have raised concern that dexmedetomidine might reduce cerebral ...
Decreased insulin-stimulated brown adipose tissue glucose uptake after short-term exercise training in healthy middle-aged men
Aims: To test the hypothesis that high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) improve brown adipose tissue (BAT) insulin sensitivity.Participants and methods: Healthy middle-aged ...
