Molecular characteristics of biogenic monoamines and their analogs

Quarterly Reviews of Biophysics, 1973
Until recently there has been very limited information concerning the molecular geometry and conformation of biogenic monoamines and this lack of knowledge has seriously hampered efforts to unravel the structure—function relationships at the molecular level.

Enzymatic sensitivity enhancement of biogenic monoamines on a chip

ELECTROPHORESIS, 2005
AbstractDetection of biogenic monoamines in nanomolar concentrations is of great importance for probing the brain chemistry and for their analytics in biological fluids. The sensitivity enhancement of amperometric detection of neurotransmitters (NTs) and their metabolites after their electrophoretic separation on a microchip is presented and is based ...

Cerebrospinal Fluid Biogenic Monoamine Analysis for Diagnosis of Primary Neurotransmitter Disorders

Indian Journal of Pediatrics, 2021
Biogenic amine neurotransmitters metabolism is a multistep pathway with pterin and pyridoxal phosphate (vitamin B6) as cofactors. A defect in biogenic amine and cofactor metabolism and vesicular transporters result in a primary neurotransmitter disorders.

Fluorescence of biogenic monoamines in the human dental pulp

Oral Surgery, Oral Medicine, Oral Pathology, 1976
Biogenic monoamines in the adrenergic nerve terminals of the human dental pulp are demonstrated by the fluorescence method of Falck and Owman. Unmyelinated nerve fibers from nerves along alveolar blood vessels may enter the pulp, although pulp nerves are composed largely of myelinated fibers. The existence of a few sympathetic fibers is demonstrated by

Effect of some monoamine oxidase inhibitors on deamination of biogenic monoamines by rat liver mitochondrial monoamine oxidase

Experientia, 1966
N-метил-N-бензилпропин иламин тормозит дезаминирование тир амина митохондриал ьной MAO в концентрациях, значи тельно более низких чем те, которые необходимы д ля торможения дезами нирования серотонина.

Cholinesterases and biogenic monoamines in ganglion semilunare (Gasseri)

Histochemie, 1970
Cholinesterase distribution in trigeminal ganglion was studied in rabbits by the thiocholine method. The presence of acetylcholinesterase conditions either a) a diffusive cytoplasmatic reaction of varying intensity — from very weak to very strong — or b) an unevenly intensively distributed reaction pronounced on the periphery of ganglion cells.

Metabolism of biogenic monoamines in the ciliated protozoan, Tetrahymena pyriformis

Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1993
1. The three-dimensional HPLC system was used to detect the presence and determine the levels of biogenic monoamines, including precursor amino acids and metabolites, simultaneously in an extract of the ciliated protozoan, Tetrahymena pyriformis. 2. Representative biogenic monoamines, such as dopamine (DA), 5-hydroxytryptamine (5-HT), epinephrine (E ...

Neurochemical changes following the administration of depleters of biogenic monoamines

Life Sciences, 1976
Abstract A variety of drugs which were thought to selectively effect the synthesis, release or reuptake of the biogenic monoamines, and thereby deplete their stores in brain, were administered to rats. The animals were given intraperitoneal injections of reserpine, α-methyl-meta-tyrosine, α-methyl-para-tyrosine, para-cholorophenylalanine and ...

Biogenic amine metabolism in biomphalaria glabrata—II. Monoamine oxidase activity

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1981
Abstract 1. 1. Monoamine oxidase (EC 1.4.3.4) activity has been detected in the tissues of Biomphalaria glabrata . The bulk of the enzyme activity is present in a 20,000 g pellet fraction. The hepatopancreas region contained the highest activity. 2. 2.

Microfluorimetric Quantitation of Biogenic Monoamines

1973
Quantitation of fluorescence intensity at the microscope level can now be accomplished by using one of several highly sensitive and commercially available micro-fluorimeters on the market. However, exact quantitative measurement of fluorescence intensity does not necessarily prove to be a correct quantitation of the fluorescent substance.
