Inherited disorders of gamma-aminobutyric acid (GABA) metabolism include succinic semialdehyde dehydrogenase (SSADH) and gamma-aminobutyric acid transaminase (GABA-T) deficiencies. The clinical features, pathophysiology, diagnosis, and management of both, and an updated list of mutations in the ALDH5A1 gene, which cause SSADH deficiency, are discussed. A database of 112 individuals (71 children...

GABA (γ-aminobutyric acid) is a four carbon non-protein amino acid that is widely distributed in plants, animals and microorganisms. As a metabolic product of plants and microorganisms produced by the decarboxylation of glutamic acid, GABA functions as an inhibitory neurotransmitter in the brain that directly affects the personality and the stress management. A wide range of traditional foods p...

The aim of the study was to assess changes in physical performance parameters progeny rats with experimental preeclampsia (EP) undergoing early and late pharmacological treatment gamma- aminobutyric acid (GABA) derivatives. Materials methods . At first stage, 3- 18-month old female EP after (from 40 th 70 day life) GABA derivatives, succicard (22mg/kg), salifen (7.5 mg/kg), phenibut (25 mg/kg) ...

Effects of amino acids and nitrogen on plant regrowth or recovery from drought stress remain largely unknown. The objectives this study were to examine how gamma-aminobutyric acid (GABA) proline, alone in combination, inorganic [ammonium nitrate (NN)] may differentially affect turf performance during rewatering, determine which specific endogenous regulated by GABA, NN priming associated with t...

Many strains of lactic acid bacteria (LAB) and bifidobacteria have exhibited strain-specific capacity to produce γ-aminobutyric acid (GABA) via their glutamic acid decarboxylase (GAD) system, which is one of amino acid-dependent acid resistance (AR) systems in bacteria. However, the linkage between bacterial AR and GABA production capacity has not been well established. Meanwhile, limited evide...

The present method describes the estimation of gamma-aminobutyric acid (GABA) from adult rat brain by thin layer chromatography (TLC). The major advantage of this TLC method is the sensitivity and repidity of estimation. About 93 to 98 percent recovery is possible by this procedure and this shows linearity up to 9 micrograms. Replicate analysis of GABA by this method shows a co-efficient variat...

Succinic semialdehyde dehydrogenase (SSADH) deficiency is a rare hereditary disorder of the CNS catabolism of gamma-aminobutyric acid (GABA), leading to accumulation of the metabolite 4-hydroxybutyrate (GHB). Here the authors report on 1.5 and 3.0 T proton MR spectroscopy in a patient with SSADH deficiency. A characteristic pattern with clearly elevated GABA levels and traces of GHB was found i...

Gamma-aminobutyric acid (GABA) and glutamate are two important amino acid neurotransmitters widely present in the nervous systems of mammals, insects, round worm, and platyhelminths, while their receptors are quite diversified across different animal phyla. However, the evolutionary mechanisms between the two conserved neurotransmitters and their diversified receptors remain elusive, and antago...

Human amniotic fluid and a mixture of eight fatty acids (FAT-M) identified in this maternal fluid (C12:0, lauric acid, 0.9 μ g%; C14:0, myristic acid, 6.9 μ g%; C16:0, palmitic acid, 35.3 μ g%; C16:1, palmitoleic acid, 16.4 μ g%; C18:0, stearic acid, 8.5 μ g%; C18:1 cis, oleic acid, 18.4 μ g%; C18:1 trans, elaidic acid, 3.5 μ g%; C18:2, linoleic acid, 10.1 μ g%) produce anxiolytic-like effects ...
