Etablierung einer Methode für die High-Performance-Liquid-Chromatography (HPLC) mit elektrochemischer Detektion (ECD) zur gleichzeitigen Messung von 3-Methoxy-4-hydroxyphenolglycol, 5-Hydroxyindolessigsäure und Homovanillinsäure im Liquor von Patienten mit Fibromyalgiesyndrom und neurologischen Erkrankungen
… 5-Hydroxyindolessigsäure (5-HIAA)und Homovanillinsäure (HVA)im Liquor von Patienten mit Fibromyalgiesyndrom (FMS)und neurologischen Erkrankungen etabliert. Beim anschließenden Gruppenvergleich fanden sich signifikante positive Korrelationen zwischen 5-HIAA und HVA in allen …

The Role of GABA in Reproductive Neuroendocrine Systems
… (5-HT), and 5-hydroxyindole acetic acid (5-HIAA) during two hormonal states with each model. In the intact rat the proestrus and estrus states were examined, and in the ovariectomized rat <em>in-vitro</em> release was determined with (OVX<sub>2</sub>) and without (OVX) estradiol …

Synthesis and characterization of Carbon Quantum Dots, ZnO and Magnetic Nanoparticles. New Analytical Applications
… of clinical (5-hydroxyindole acetic acid, 5-HIAA), environmental (4-nitrophenol) and food (tannic acid) concern have been used as model analytes. Also, the functionalization of ZnO nanoparticles was addressed with the aim to use them as lubricant additives and as nanosensors. Firstly, the …

Electrical stimulation of reward sites in the ventral tegmental area of the rat increases dopamine transmission in the nucleus accumbens as measured by in vivo microdialysis
… acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) in the nucleus accumbens of the rat, prior to, during, and after 15-min periods of electrical brain-stimulation at sites in the ventral tegmental area (VTA) that supported intracranial self-stimulation (ICSS). In the first experiment, both …

FACTORS THAT AFFECT SOCIAL HIERARCHY AND THE INFLUENCE OF SOCIAL RANK AND MENSTRUAL CYCLE ON COCAINE SELF-ADMINISTRATION IN FEMALE CYNOMOLGUS MONKEYS
… fluid concentrations of the 5-HT metabolite 5-HIAA, which were significantly higher in the animals that eventually became subordinate and latency to touch a novel object, which was significantly lower in eventual subordinate monkeys. Age, body weight, locomotor activity in a novel environment, …

Investigations of Serotonin Metabolism in Mammalian and Other Deuterostome Model Systems
… (5-HT-SO4) and 5-hydroxyindole acetic acid (5-HIAA) in these organisms. A novel 5-HT metabolite in the rat (Rattus norvegicus ), 5-hydroxyindole thiazolidine carboxylic acid (5-HITCA), was characterized via mass spectrometry (MS) and further investigated using CE. Levels of 5-HT and some of its …

The Effect of Organophosphate Exposure on Neocortical, Hippocampal and Striatal Monoamines: A Potential Substrate for Chronic Psychiatric, Cognitive and Motor Dysfunction
… except for 5-hydroxyindoleacetic acid (5-HIAA) in the striatum. Therefore, the final experiment employed a more powerful design to focus on monoamine levels during, or shortly after, the change in AChE activity that rapidly follows exposure to 200mg/kg CPS. This experiment also employed a …

The effects of neonatal/juvenile heat stress and varying L- tryptophan levels on growth parameters, meat quality, and brain neurotransmitter levels in turkeys
… gain. Serotonin, 5 hydroxyindole acetic acid (5-HIAA), and norepinephrine levels increased linearly with dietary tryptophan supplementation in the four brain regions analyzed while linear increases in L-dihydroxyphenylalanine (L·DOPA) occurred in all regions analyzed except for the cerebellum …

Analysis of rat brain lipids and metabolites after antidepressant drug treatment
… its metabolite 5-hydroxyindole-3-acetic acid (5-HIAA) in tissue samples from the PFC, HP and ST. In contrast, carmofur failed to significantly alter brain levels of dopamine, noradrenaline and the dopamine metabolite 3, 4- dihydroxyphenylacetic acid (DOPAC). In conclusion, findings of this …

Biochemical aspects of Tourette's Syndrome
… In addition, no change in brain 5-HT or 5-HIAA concentrations or 5-HT turnover, was found. Despite contrasting results from human and animal studIes, a role for nicotine in the mediation of tic-like movements is indicated. The relevance of the kynurenine pathway to TS and the potential role …

Developmental Monoamine Signaling Impacts Adult Affective and Aggressive Behaviors
… and DOPAC content is increased while brainstem 5-HIAA content is decreased in high aggression. Taken together, these data suggest that genetic and pharmacologic factors impacting dopamine and serotonin signaling during sensitive developmental periods confer risk for aggressive and emotional …

Pesticides and pesticide combinations on brain neurochemistry
… norepinephrine) and indolamines (serotonin and 5-HIAA). In general low doses of permethrin and endosulfan alone and in combination (EN 2.15 + PR 15 mg/kg) altered the levels of catecholamines and indolamines in both studies with adult mice and mice dosed as juveniles and re-challenged as adults. …
