Fresh peaches are highly perishable and they deteriorate quickly during low temperature storage which results in losses in nutritional quality. To prevent these adverse effects, peach fruits were treated by dipping with γ-aminobutyric acid (GABA; 2, 4 and 6 mM) immediately after harvest and then stored at 1 °C for 7, 14, 21, and 28 days. Peach fruits treated with GABA exhibited higher flesh fir...

Most of the actions of neurosteroids on the central nervous system are mediated through allosteric modulation of the gamma-aminobutyric acid type A (GABA(A)) receptor, but a direct effect of GABA on the regulation of neurosteroid biosynthesis has never been investigated. In the present report, we have attempted to determine whether 3beta-hydroxysteroid dehydrogenase (3beta-HSD)-containing neuro...

Methods using dialysis or ultrafiltration are described for the collection of extracellular fluid in rumen contents for analysis of amino acids. Marked differences in the concentration of aspartic acid, glutamic acid, and alanine were found in samples of either diffusate or ultrafiltrate and in clarified acidified rumen liquor. Concentrations are given for aspartic acid, glutamic acid, alanine,...

This study investigated the effect of preharvest treatment 0.25 mM methyl jasmonate (MeJA) and 0.5 salicylic acid (SA) on quality parameters, most important secondary metabolites (lycopene, ?-carotene, ascorbic acid, total phenolics, flavonoids), antioxidant activities, amino contents ‘Kumato’ tomato. Treatments with MeJA SA led to an increase yield per plant were effective in maintaining fruit...

The establishment of synaptic connections and their refinement during development require neural activity. Increasing evidence suggests that spontaneous bursts of neural activity within an immature network are mediated by gamma-aminobutyric acid via a paradoxical excitatory action. Our data show that in the developing hippocampus such synchronous burst activity is generated in the hilar region ...
