Synthesis and evaluation in monkey of two sensitive 11C-labeled aryloxyanilide ligands for imaging brain peripheral benzodiazepine receptors in vivo.
We sought to develop (11)C-labeled ligands for sensitive imaging of brain peripheral benzodiazepine receptors (PBR) in vivo. Two aryloxyanilides with high affinity for PBR were identified andExpand

High brain myo-inositol levels in the predementia phase of Alzheimer's disease in adults with Down's syndrome: a 1H MRS study.
OBJECTIVE An extra portion of chromosome 21 in Down's syndrome leads to a dementia in later life that is phenotypically similar to Alzheimer's disease. Down's syndrome therefore represents a modelExpand

Brain metabolite concentration and dementia severity in Alzheimer’s disease
Objective: 1H-MRS studies have shown abnormalities in brain levels of myo-inositol (mI) and N-acetyl aspartate (NAA) in AD, but the relation of these abnormalities with dementia severity was notExpand

Identification and regional distribution in rat brain of radiometabolites of the dopamine transporter PET radioligand [11C]PE2I
PurposeWe aimed to determine the composition of radioactivity in rat brain after intravenous administration of the dopamine transporter radioligand, [11C]PE2I.MethodsPET time-activity curves (TACs)Expand

Energy Consumption by Phospholipid Metabolism in Mammalian Brain
Until recently, brain phospholipid metabolism was thought to consume only 2% of the ATP consumed by the mammalian brain as a whole. In this paper, however, we calculate that 1.4% of total brain ATPExpand

Single-step high-yield radiosynthesis and evaluation of a sensitive 18F-labeled ligand for imaging brain peripheral benzodiazepine receptors with PET.
Elevated levels of peripheral benzodiazepine receptors (PBR) are associated with activated microglia in their response to inflammation. Hence, PBR imaging in vivo is valuable for investigating brainExpand

Increased Permeability-Glycoprotein Inhibition at the Human Blood–Brain Barrier Can Be Safely Achieved by Performing PET During Peak Plasma Concentrations of Tariquidar
The permeability-glycoprotein (P-gp) efflux transporter is densely expressed at the blood–brain barrier, and its resultant spare capacity requires substantial blockade to increase the uptake of avidExpand

PET imaging of the dopamine transporter with 18F-FECNT: a polar radiometabolite confounds brain radioligand measurements.
UNLABELLED 18F-2beta-Carbomethoxy-3beta-(4-chlorophenyl)-8-(2-fluoroethyl)nortropane (18F-FECNT), a PET radioligand for the dopamine transporter (DAT), generates a radiometabolite that enters the ratExpand

Enantioselective and diastereoselective aspects of the oxidative metabolism of metoprolol.
Enantio- and diastereoselective aspects of oxidative metabolism of metoprolol (1) were examined in the presence of rat liver and human liver microsomes using a pseudoracemate of 1, made up of equalExpand

Identification of Two Molecular Species of Rat Brain Phosphatidylcholine that Rapidly Incorporate and Turn Over Arachidonic Acid In Vivo
Abstract: In vivo rates of arachidonic acid incorporation and turnover were determined for molecular species of rat brain phosphatidylcholine (PtdCho) and phosphatidylinositol (PtdIns).Expand
