Recent studies of the hippocampus have suggested that a network of genes is associated with the regulation of the GAD₆₇ (GAD1) expression and may play a role in γ-amino butyric acid (GABA) dysfunction in schizophrenia (SZ) and bipolar disorder (BD). To obtain a more detailed understanding of how GAD₆₇ regulation may result in GABAergic dysfunction, we have developed an in vitro model in which G...

Background: Gamma-amino butyric acid (GABA) agonists have been effective in the treatment of withdrawal from benzodiazepines, sedatives and alcohol, and reducing the craving for cocaine. Valproate is a GABAergic drug effective in the treatment of neuropathic pain and also in withdrawal from benzodiaepines, sedatives, and alcohol. The purpose of this double-blind trial was to evaluate the ef...

Fluid accumulation is critical for lung distension and normal development. The multi-subunit γ-amino butyric acid type A receptors (GABAA) mainly act by mediating chloride ion (Cl-) fluxes. Since fetal lung actively secretes Cl--rich fluid, we investigated the role of GABAA receptors in fetal lung development. The physiological ligand, GABA, and its synthesizing enzyme, glutamic acid decarboxyl...

abstract this study aimed to investigate the effects of different levels of the amino acid lysine on growth performance, feed efficiency and body composition of juvenile snow trout (schizothorax zarudnyi). for this purpose, 150 fish with average weight 22.51±0.28 g fed with five levels of dietary amino acid lysine including 0 (control), 7, 12, 17 and 22 g/kg diet, for 8 weeks. fish fed two time...

Epilepsy is a neurological disorder characterized by excessive electrical discharge in brain, which causes seizures. The therapeutic strategy in countering epilepsy involves reducing neuronal excitability through different mechanistic pathway. Most therapeutics currently used in the treatment of epilepsy is either directed towards blocking voltage-gated sodium and calcium channels or potentiati...

N-Phthaloyl GABA was administrated daily (50 mg/Kg body weight-i.p) to Wistar rats for 21 days and circadian rhythms of thiobarbituric acid reactive substances (TBARS) and antioxidants such as reduced glutathione (GSH), catalase (CAT) and superoxide dismutase (SOD) were studied under constant light (LL) conditions. Delayed acrophase of TBARS and advanced acrophase of antioxidants (GSH, CAT and ...

Gamma-aminobutyric acid (GABA) is a non-protein amino known for its role in the nervous system of animals. However, research has also revealed presence and function plants recently. In plants, GABA signal molecule involved multiple physiological processes, including stress response, growth, development. This review aims to present thorough summary current knowledge regarding plants. We begin by...

To investigate the physiological effects of melatonin receptors in the Xenopus tectum, we have used the fluorescent indicator Fluo-4 AM to monitor calcium dynamics of cells in tectal slices. Bath application of KCl elicited fluorescence increases that were reduced by melatonin. This effect was stronger at the end of the light period than at the end of the dark period. Melatonin increased gamma-...
