Filter by:Investigators propose to develop hyperpolarized [13C]-labeled pyruvate as potential imaging probes to assess two essential in vivo processes in cerebral metabolism: oxidative metabolism and synthesis of a neurotransmitter in this observational study.
This study investigates the influence of dietary nitrate supplementation on cardiovascular health and physical and cognitive performance in older adults. Participants will receive both a nitrate containing beetroot juice for 10 days and a nitrate depleted beetroot juice for 10 days
This project tend to investigate the affection of ketone bodies on brain metabolism. This will be done by measuring human cerebral uptake of energy substrates, together with functional parameters, using PET imaging and appropriate radiotracers under hyperketonemia in healthy subjects by ketone infusion. Hypotheses 1. Increased levels of ketone bodies in healthy subjects leads to decreased glucose uptake by brain cells contributing to hyperglycaemia. 2. Increased levels of ketone bodies in healthy subjects leads to increased cerebral blood flow. 3. Altered oxygen consumption during hyperketonemia in healthy subjects.
Dopamine receptor occupancy and brain metabolism were measured using positron emission tomography after the administration of aripiprazole. Working memory performance was also measured using N-back task. The investigators explored the relationship between changes in brain metabolism and working memory performance.
