Simultaneous Determination of 3-Methoxy-4-Hydroxyphenyl-Glycol, Homovanillic Acid, and 5-Hydroxyindoleacetic Acid in Plasma by High Performance Liquid Chromatography [PDF]

, 1989
A rapid, reliable, and sensitive method for simultaneous determination of 3-methoxy-4-hydroxyphenylglycol (MHPG), Homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5- HIAA) in plasma is described.

The Association between Elevated Levels of Peripheral Serotonin and Its Metabolite – 5-Hydroxyindoleacetic Acid and Bone Strength and Metabolism in Growing Rats with Mild Experimental Chronic Kidney Disease - Fig 6

, 2016
The correlation between ALP and 5-HIAA serum levels in rats with CKD (panel A) and controls (panel B). Abbreviations: ALP = alkaline phosphatase, 5-HIAA = 5-hydroxyindoleacetic acid.

Use of alumina, sephadex G10, and ion-exchange columns to purify samples for determination of epinephrine, norepinephrine, dopamine, homovanillic acid, and 5-hydroxyindoleacetic acid in urine

, 1982
We investigated the usefulness of small Sephadex columns, prepared in Pasteur pipettes, in purifying samples to be analyzed for catecholamines, homovanillic acid, and 5-hydroxyindoleacetic acid. After free catecholamines in urine samples were purified on

The role of hydroxyindoles in protecting neuronal cultures from ferroptosis

Cell Death Discovery
Hydroxyindoles are organic compounds characterized by a hydroxyl group attached to an indole ring. One notable example is 5-hydroxyindole, which can be found in humans, plants, and microorganisms. The structure of 5-hydroxyindole is integral to molecules

Human platelet 5-hydroxyindoleacetic acid concentrations are meager and unlikely to be physiologically active or play a role in inflammation

Hematology
Objectives A crucial role for platelet 5-hydroxyindoleacetic acid (5-HIAA, the principal serotonin metabolite) in human immune response and inflammation has been claimed. We have attempted to assess the likelihood of such a role for platelet 5-HAA.

Direct measurement of homovanillic, vanillylmandelic and 5-hydroxyindoleacetic acids in urine by capillary electrophoresis [PDF]

, 2000
Separation conditions in CE, with a neutral coated capillary and reversed polarity, have been optimised to make direct measurement of vanillylmandelic acid, homovanillic acid and 5-hydroxyindoleacetic acid possible in urine samples without pre-treatment.

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

, 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 ...

Homovanillic acid and 5-hydroxyindoleacetic acid modifications in CSF of patients with stroke and multi-infarct dementia.

, 1985
Thirty four patients who had complete ischemic stroke confirmed by neurologic examination, were divided into three groups according to the time elapsed between the first signs of stroke and lumbar puncture: group A, 22-47 h; group B, 48-71 h; group C, 72-
