Dextromethorphan inhibits 5-hydroxytryptamine uptake by human blood platelets and decreases 5-hydroxyindoleacetic acid content in rat brain

open access: yes, 1975
The effect of dextromethorphan on the uptake and metabolism of 5-hydroxytryptamine (5-HT) was studied in human blood platelets and in rat brain. In the concentration of 120 nM dextromethorphan inhibited the uptake of 5-HT (1 μM) into platelets by 50 ...

Plasma 5-hydroxyindoleacetic acid as an indicator of MAO-A inhibition in brain and peripheral tissues

open access: yes, 1993
We have examined the changes induced by the monoamine oxidase (MAO; EC 1.4.3.4) inhibitors tranylcypromine, clorgyline, and deprenyl on MAO activity and 5-hydroxytryptamine (serotonin, 5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) content in rat brain ...

Nanostructured lead-acid negative electrode with reduced graphene oxide

open access: yes, 2021
Aim of this work is to develop a new nano-structured and nano-composite lead acid negative electrode with reduced graphene oxide (rGO). Nanostructured electrodes are fabricated by template electrodeposition of lead nanowires on a lead current collector ...

Measurement of plasma 5-hydroxyindoleacetic acid as a possible clinical surrogate marker for the action of antivascular agents.

open access: yes, 2001
BACKGROUND: Serotonin (5HT), a naturally occurring vasoactive substance, is released from platelets into plasma under various pathological conditions.

Urinary Excretion of 5-Hydroxyindoleacetic Acid, Serotonin and 6-Sulphatoxymelatonin in Normoserotonemic and Hyperserotonemic Autistic Individuals

open access: yes, 2010
Objective: A substantial proportion of individuals with autism have elevated levels of platelet serotonin (5-HT). We examined whether platelet hyperserotonemia is associated with increased gut 5-HT synthesis, altered 5-HT catabolism or altered melatonin ...

Insights into small-molecule neurotransmitter levels and distribution during tissue regeneration in an ear pinna model in mice

open access: yesScientific Reports
Best known for their functions in the nervous system, neurotransmitters also play prominent roles in wound healing. The study analysed the spatiotemporal expression of acetylcholine, dopamine, gamma-aminobutyric acid, serotonin, and its metabolite, 5 ...
