Positron Emission Tomography Imaging of Macrophages in Atherosclerosis with F-18-GE-180, a Radiotracer for Translocator Protein (TSPO)
Intraplaque inflammation plays an important role in the progression of atherosclerosis.) The 18 kDa translocator protein (TSPO) expression is upregulated in activated macrophages, representing a potential target to identify ...
Cessation of anti-VLA-4 therapy in a focal rat model of multiple sclerosis causes an increase in neuroinflammation
BackgroundPositron emission tomography (PET) can be used for in vivo evaluation of the pathology associated with multiple sclerosis. We investigated the use of longitudinal PET imaging and the 18-kDa translocator protein ...
68Ga-DOTA chelate, a novel imaging agent for assessment of myocardial perfusion and infarction detection in a rodent model
<p>Background<br />Magnetic resonance imaging (MRI) with Gadolinium 1,4,7,10-tetraazacyclododecane-N′,N″,N′′′,N″″-tetraacetic acid (Gd-DOTA) enables assessment of myocardial perfusion during first-pass of the contrast ...
Brain structural alterations in autism and criminal psychopathy
The goal of this study was to elucidate the anatomical brain basis of social cognition through two disorders with distinctively different phenotypes of social interaction. We compared structural MR images of 20 individuals ...
First-in-Human Study of 68 Ga-DOTA-Siglec-9, PET Ligand Targeting Vascular Adhesion Protein 1
Sialic acid-binding immunoglubulin-like lectin 9 (Siglec-9) is a ligand of vascular adhesion protein 1 (VAP-1). A gallium 68-labeled peptide of Siglec-9, <sup>68</sup>Ga-DOTA-Siglec-9, holds promise as a novel PET tracer ...
Seasonal variation in the brain μ-opioid receptor availability
<p>Seasonal rhythms influence emotion and sociability. The brain μ-opioid receptor (MOR) system modulates a multitude of seasonally varying socioemotional functions, but its seasonal variation remains elusive with no ...
Prognostic imaging biomarkers for diabetic kidney disease (iBEAt): study protocol
<b>Background:</b> Diabetic kidney disease (DKD) remains one of the leading causes of premature death in diabetes. DKD is classified on albuminuria and reduced kidney function (estimated glomerular filtration rate (eGFR)) ...
Association between [Ga-68]NODAGA-RGDyK uptake and dynamics of angiogenesis in a human cell-based 3D model
Radiolabeled RGD peptides targeting expression of alpha(v)beta(3) integrin have been applied to in vivo imaging of angiogenesis. However, there is a need for more information on the quantitative relationships between RGD ...
Exploiting Glutamine Consumption in Atherosclerotic Lesions by Positron Emission Tomography Tracer (2S,4R)-4-F-18-Fluoroglutamine
Increased glutamine metabolism by macrophages is associated with development of atherosclerotic lesions. Positron emission tomography/computed tomography (PET/CT) with a glutamine analog (2S,4R)-4-F-18-fluoroglutamine ...
Intramyocellular lipid accumulation after sprint interval and moderate-intensity continuous training in healthy and diabetic subjects
The effects of sprint interval training (SIT) on intramyocellular (IMCL) and extramyocellular (EMCL) lipid accumulation are unclear. We tested the effects of SIT and moderate-intensity continuous training (MICT) on IMCL ...
