A correlation between changes in gamma-aminobutyric acid metabolism and seizures induced by antivitamin B6. (1/160)

The effects of DL-penicillamine (DL-PeA), hydrazine and toxopyrimidine (TXP, 2-methyl-6-amino-5-hydroxymethylpyrimidine) on gamma-aminobutyric acid (GABA) metabolism in mouse brain were studied. All these compounds inhibited the activity of glutamate decarboxylase [EC 4.1.1.15] (GAD) and slightly inhibited that of 4-aminobutyrate: 2-oxoglutarate aminotransferase [EC 2.6.1.19] (GABA-T). In contrast, very different effects were observed on GABA levels; hydrazine caused a marked increase, DL-PeA had no effect, and TXP caused a slight decrease in the content of the amino acid. These results could be described by an equation which related the excitable state to changes in the flux of the GABA bypass. Since the values obtained from the equation clearly reflect the seizure activity, it is suggested that the decreased GABA flux might be a cause of convulsions induced by these drugs.  (+info)

The irreversible gamma-aminobutyric acid (GABA) transaminase inhibitor gamma-vinyl-GABA blocks cocaine self-administration in rats. (2/160)

gamma-Vinyl gamma-aminobutyric acid (GABA) (GVG) is an irreversible inhibitor of GABA transaminase, the primary enzyme involved in GABA metabolism. Acute administration of GVG increases brain GABA levels and blocks cocaine-induced locomotor activity, cocaine-induced lowering of brain stimulation reward thresholds, and cocaine-induced conditioned place preference. To further evaluate the effects of GVG on cocaine-induced reward, we examined its effects on cocaine self-administration in male Wistar rats on fixed ratio 5 and progressive ratio schedules of reinforcement. Additionally, the effects of GVG on operant responding for a food reward were examined on the same two schedules to determine whether the effects of GVG were specific to cocaine reward or generalized to other types of reward. GVG dose dependently decreased responding for cocaine on both schedules of reinforcement, suggesting that GVG attenuated the reward value of the cocaine. Responding for food was also decreased by GVG, suggesting that the effects of increased GABA levels induced by GVG may have a general effect on central reward systems. Data from this and other studies indicate that GVG does not induce motor impairment, decrease spontaneous locomotor activity, or induce catalepsy. Taken together, these data suggest that increases in GABAergic activity induced by GVG have an attenuating effect on centrally mediated reward systems and that the GABA system may be a useful target in the development of new therapeutic strategies for cocaine addiction.  (+info)

The mature size of rat 4-aminobutyrate aminotransferase is different in liver and brain. (3/160)

The amino acid sequence predicted from a rat liver cDNA library indicated that the precursor of beta-AlaAT I (4-aminobutyrate aminotransferase, beta-alanine-oxoglutarate aminotransferase) consists of a mature enzyme of 466 amino acid residues and a 34-amino acid terminal segment, with amino acids attributed to the leader peptide. However, the mass of beta-AlaAT I from rat brain was larger than that from rat liver and kidney, as assessed by Western-blot analysis, mass spectroscopy and N-terminal sequencing. The mature form of beta-AlaAT I from the brain had an ISQAAAK- peptide on the N-terminus of the liver mature beta-AlaAT I. Brain beta-AlaAT I was cleaved to liver beta-AlaAT I when incubated with fresh mitochondrial extract from rat liver. These results imply that mature rat liver beta-AlaAT I is proteolytically cleaved in two steps. The first cleavage of the motif XRX( downward arrow)XS is performed by a mitochondrial processing peptidase, yielding an intermediate-sized protein which is the mature brain beta-AlaAT I. The second cleavage, which generates the mature liver beta-AlaAT I, is also carried out by a mitochondrial endopeptidase. The second peptidase is active in liver but lacking in brain.  (+info)

Effects of blocking GABA degradation on corticotropin-releasing hormone gene expression in selected brain regions. (4/160)

PURPOSE: The gamma-aminobutyric acid (GABA) degradation blocker gamma-vinyl-GABA (VGB) is used clinically to treat seizures in both adult and immature individuals. The mechanism by which VGB controls developmental seizures is not fully understood. Specifically, whether the anticonvulsant properties of VGB arise only from its elevation of brain GABA levels and the resulting activation of GABA receptors, or also from associated mechanisms, remains unresolved. Corticotropin-releasing hormone (CRH), a neuropeptide present in many brain regions involved in developmental seizures, is a known convulsant in the immature brain and has been implicated in some developmental seizures. In certain brain regions, it has been suggested that CRH synthesis and release may be regulated by GABA. Therefore we tested the hypothesis that VGB decreases CRH gene expression in the immature rat brain, consistent with the notion that VGB may decrease seizures also by reducing the levels of the convulsant molecule, CRH. METHODS: VGB was administered to immature, 9-day-old rats in clinically relevant doses, whereas littermate controls received vehicle. RESULTS: In situ hybridization histochemistry demonstrated a downregulation of CRH mRNA levels in the hypothalamic paraventricular nucleus but not in other limbic regions of VGB-treated pups compared with controls. In addition, VGB-treated pups had increased CRH peptide levels in the anterior hypothalamus, as shown by radioimmunoassay. CONCLUSIONS: These findings are consistent with a reduction of both CRH gene expression and secretion in the hypothalamus, but do not support an indirect anticonvulsant mechanism of VGB via downregulation of CRH levels in limbic structures. However, the data support a region-specific regulation of CRH gene expression by GABA.  (+info)

Effect of gonadal steroids and gamma-aminobutyric acid on LH release and dopamine expression and activity in the zona incerta in rats. (5/160)

A dopaminergic system in the zona incerta stimulates LH release and may mediate the positive feedback effects of the gonadal steroids on LH release. In this study the mechanisms by which steroids might increase dopamine activity in the zona incerta were investigated. In addition, experiments were conducted to determine whether the inhibitory effects of gamma-aminobutyric acid (GABA) on LH release in the zona incerta are due to suppression of dopamine activity in this area or conversely whether the stimulatory effects of dopamine on LH release are due to suppression of a tonic inhibitory GABAergic system. Ovariectomized rats were treated s.c. with oil, 5 micrograms oestradiol benzoate or 5 micrograms oestradiol benzoate followed 48 h later by 0.5 mg progesterone, and killed 54 h after the oestradiol benzoate injection. At this time the LH concentrations were suppressed in the oestradiol benzoate group and increased in the group treated with oestradiol benzoate and progesterone. The ratio of tyrosine hydroxylase:beta-actin mRNA in the zona incerta was significantly increased by the oestradiol benzoate treatment, but the addition of progesterone resulted in values similar to those in the control group. At the same time, the progesterone treatment increased tyrosine hydroxylase activity in the zona incerta as indicated by an increase in L-dihydroxyphenylalanine (L-DOPA) accumulation after 100 mg 3-hydroxybenzylhydrazine hydrochloric acid (NSD1015) kg-1 and an increase in dopamine release as indicated by a increase in dihydroxyphenylacetic acid (DOPAC) concentrations (one of the major metabolites of dopamine). Ovariectomized rats treated with oestradiol benzoate plus progesterone were also injected i.p. with 75 mg gamma-acetylenic GABA kg-1 (a GABA transaminase inhibitor) to increase GABA concentrations in the brain. This treatment had no effect on the ratio of tyrosine hydroxylase:beta-actin mRNA but decreased L-DOPA accumulation and DOPAC concentrations in the zona incerta, indicating a post-translational inhibition of dopamine synthesis and release. Treatment of ovariectomized rats with oestradiol benzoate followed by 100 mg L-DOPA i.p. to increase dopamine concentrations in the whole brain had no effect on glutamic acid decarboxylase mRNA expression in the zona incerta, although it increased the glutamic acid decarboxylase:beta-actin mRNA ratio in other hypothalamic areas (that is, the medical preoptic area, ventromedial nucleus and arcuate nucleus). In conclusion, the steroids act to increase dopamine activity in different ways: oestrogen increases tyrosine hydroxylase mRNA expression and progesterone acts after translation to increase tyrosine hydroxylase activity and dopamine release (as indicated by increases in DOPAC concentrations). This latter effect may be due to progesterone removing a tonic GABAergic inhibition from the dopaminergic system.  (+info)

The inhibitory effects of (gamma)-aminobutyric acid (GABA) on growth hormone secretion in the goldfish are modulated by sex steroids. (6/160)

Double-labelling studies at the electron microscopic level demonstrated that gamma-aminobutyric acid (GABA)-immunoreactive nerve endings are associated with growth-hormone-secreting cells in the proximal pars distalis of the goldfish pituitary gland, suggesting that GABA may be important for the control of growth hormone release in this species. An in vitro assay for GABA-transaminase activity demonstrated that the pituitary is a site for the metabolism of GABA to succinic acid. In vitro, GABA or the GABA antagonists bicuculline and saclofen did not affect the rate of growth hormone release from dispersed pituitary cells in static incubation. In contrast, intracerebroventricular injection of GABA reduced serum growth hormone levels within 30 min. During the seasonal gonadal cycle, intraperitoneal injection of GABA was without effect in sexually regressed goldfish, but caused a significant decrease in serum growth hormone levels in sexually recrudescent animals. Intraperitoneal implantation of solid silastic pellets containing oestradiol increased serum GH levels fivefold in sexually regressed and recrudescent goldfish; in both groups, GABA suppressed the oestradiol-stimulated increase in circulating growth hormone levels. The effect of oestradiol on basal serum growth hormone levels was specific since progesterone and testosterone were without effect. However, in recrudescent animals treated with progesterone and testosterone, the inhibitory effects of GABA on serum growth hormone levels were absent, indicating a differential role for these steroids in growth hormone release. Taken together, these results demonstrate that GABA has an inhibitory effect on growth hormone release in goldfish.  (+info)

Recovery of visual field constriction following discontinuation of vigabatrin. (7/160)

Epilepsy patients treated with vigabatrin may develop symptomatic or asymptomatic concentric visual field constriction due to GABA-associated retinal dysfunction. The prevalence and course of this side effect are not established yet; in previously reported adult patients the visual disturbances seem to be irreversible. We present two patients with a significant improvement of visual field constriction and retinal function after the discontinuation of vigabatrin. These findings suggest that vigabatrin-associated retinal changes are at least partly reversible in some patients, and that these patients may benefit significantly from a withdrawal of vigabatrin. Larger scale clinical studies are needed to identify predictive factors both for the occurrence and reversibility of vigabatrin-associated visual field defects.  (+info)

Increased mesolimbic GABA concentration blocks heroin self-administration in the rat. (8/160)

Opiate reinforcement has been hypothesized to be mediated by an inhibition of mesolimbic gamma-aminobutyric acid (GABA) release that subsequently disinhibits ventral tegmental area (VTA) dopamine neurons. In support of this hypothesis, this study demonstrates that when administered directly into the lateral ventricle, the VTA, or the ventral pallidum, but not the nucleus accumbens, gamma-vinyl-GABA (GVG, an irreversible GABA-transaminase inhibitor, 20-50 microg) dose dependently blocked heroin (0.06 mg/kg) self-administration (SA), as assessed by an increase in heroin SA at low doses of GVG and an initial increase followed 1 to 2 h later by a blockade of heroin SA at higher GVG doses. This effect lasted 3 to 5 days. In drug-naive rats, intra-VTA GVG pretreatment also prevented or delayed acquisition of heroin SA for 2 days. This GVG effect was prevented or reversed by systemic or intra-VTA pretreatment with the GABA(B) antagonist 2-hydroxysaclofen, but not the GABA(A) antagonist bicuculline. Similarly, coadministration of heroin with aminooxy-acetic acid (1-4 mg/kg) or ethanolamine-O-sulfate (50-100 mg/kg), two reversible GABA transaminase inhibitors, dose dependently reduced heroin reinforcement. Coadministration of (+/-)-nipecotic acid (0.1-5 mg/kg) with heroin, or intra-VTA or -ventral pallidum pretreatment with (+/-)-nipecotic acid (10 microg) or NO-711 (2 microg), two GABA uptake inhibitors, significantly increased heroin SA behavior, an effect also blocked by systemic 2-hydroxysaclofen, but not bicuculline. Taken together, these experiments, for the first time, demonstrate that pharmacological elevation of mesolimbic GABA concentration blocks heroin reinforcement by activating GABA(B) receptors, supporting the GABAergic hypothesis of opiate reinforcement and the incorporation of GABA agents in opiate abuse treatment.  (+info)

GABA (γ-aminobutyric acid) is a non protein amino acid that has been reported to accumulate in a number of plant species when subjected to high salinity and many other environmental constraints. However, no experimental data are to date available on the molecular function of GABA and the involvement of its metabolism in salt stress tolerance in higher plants. Here, we investigated the regulation of GABA metabolism in Arabidopsis thaliana at the metabolite, enzymatic activity and gene transcription levels upon NaCl stress. We identified the GABA transaminase (GABA-T), the first step of GABA catabolism, as the most responsive to NaCl. We further performed a functional analysis of the corresponding gene POP2 and demonstrated that the previously isolated loss-of-function pop2-1 mutant was oversensitive to ionic stress but not to osmotic stress suggesting a specific role in salt tolerance. NaCl oversensitivity was not associated with overaccumulation of Na+ and Cl- but mutant showed a slight decrease in K+.

Gabapentin was conceived as part of a drug discovery program to treat neurological diseases, including epilepsy, spasticity, multiple sclerosis, and other central nervous system (CNS) disorders. This program began in the early 1970s at the German company, Goedecke, A.G., in Freiburg, Germany, which was a part of Warner-Lambert (now incorporated into Pfizer). The history of this project included chemical attempts to inhibit g-amino-butyric acid (GABA) degradation in brain with compounds that inhibited the catalytic pyridoxylphosphate of GABA-transaminase. It had already been known for some time that GABA was a key inhibitory neurotransmitter, and that experimental chemical impairment of GABA systems could cause seizures in experimental animals. The GABA transaminase project at Goedecke had progressed a compound to phase I clinical trials, but these were halted because of safety concerns. The chemical matter developed within the GABA transaminase project had no direct relationship to the chemical ...

The high frequency and poor prognosis of breast-to-brain metastasis (BBM) indicates the need for detailed studies of metastatic breast cancer cells, the brain microenvironment, and the interactions between the two that lead to breast cancer colonization and proliferation. Because neurotransmitters are a major component of the brain microenvironment, we examined fresh tissue and cells from recent surgical specimens of BBM to determine if they expressed CNS-specific neurotransmitter characteristics. We found that BBM cells expressed higher levels of the classical neurotransmitter receptors relative to primary breast cancer, and that, overall, they had a GABAergic phenotype similar to that of neuronal cells. Specifically, GABAAR, GAD67, GABA transporter, and GABA transaminase were highly expressed in BBM cells indicating that they utilize GABA. Moreover, we determined BBM cells exploit the GABA shunt in order to enhance energy production and proliferative potential in vitro. BBM cells also ...

TRIGEMINAL NEURALGIA IS a well known clinical entity characterized by agonizing, paroxysmal, and lancinating facial pain, often triggered by movements of the mouth or eating. Historical reviews of facial pain have attempted to describe this severe pain over the past 2.5 millennia. The ancient Greek physicians Hippocrates,. Aretaeus, and Galen, described kephalaigias, but their accounts were vague and did not clearly correspond with what we now term trigeminal neuralgia. The first adequate description of trigeminal 4-Aminobutyrate aminotransferase neuralgia was given in 1671, followed by a fuller description by physician John Locke in 1677. Andre described the convulsive-like condition in 1756, and named it tic douloureux; in 1773, Fothergill described it as a painful affection of the face; and in 1779, John Hunter more clearly characterized the entity as a form of nervous disorder with reference to pain of the teeth, gums, or tongue where the disease does not reside. One hundred ...

TY - JOUR. T1 - γ-Aminobutyric acid stimulates intrinsic inhibitory and excitatory nerves in the guinea-pig intestine. AU - Krantis, Anthony. AU - Costa, Marcello. AU - Furness, John B.. AU - Orbach, Joseph. PY - 1980/1/1. Y1 - 1980/1/1. N2 - The sites of action of γ-aminobutyric acid (GABA) were examined in preparations of the distal colon and ileum of guinea pigs. GABA caused transient relaxations of the longitudinal and circular muscle of the colon and transient constractions followed by relaxation of the muscle of the ileum. The responses of both parts of the intestine were antagonized by tetrodotoxin and by bicuculline. Nerve-free preparations of the longitudinal muscle of the ileum were not affected by GABA, even in concentrations up to 10−4 g/ml. There was a marked tachyphylaxis of the responses to GABA. Relaxations in response to GABA were not affected by pentolinium or by a combination of phetolamine and propranolol. Contractions in response to GABA were blocked by hyoscine. Neither ...
1. γ-Aminobutyric acid (GABA) immunoreactivity is demonstrated by the indirect immunofluorescence technique in a small population of retinal neurons cultured from human fetuses. 2. Positive staining was restricted to a few cells and could be observed as soon as the cells became attached to the substrate (within 5 hr). It is therefore concluded that the GABA-positive cells are determined prenatally. 3. The GABA-positive cells grow processes during development in culture and remain constant in numbers. These cells have a different morphology from either GFAP-positive cells or serotinin-accumulating cells. 4. It is suggested that the GABA-positive cells in culture are probably amacrine neurones. 5. Cultures of human retinal dissociates may therefore provide an alternative means of studying specific cell types should a constant supply of living human retinas be difficult to obtain. γ-Aminobutyric acid (GABA) immunoreactivity is demonstrated by the indirect immunofluorescence technique in a small
GABA(γ-aminobutyric acid) is a non-protein amino acid that can be accumulated via permease-mediated uptake by Uga4p, Put4p, and Gap1p. GABA can also be produced via glutamate degradation by the glutamate decarboxylase, this variant of the pathway includes a 2-oxoglutarate-dependent 4-aminobutyrate transaminase and an NAD+-dependent dehydrogenase. This combination of enzymes has been documented in bacteria and animals and in some plants. Regarding the hydrogenase, NAD-specific variants have been studied from many bacteria, plant and animals ...

One of the most commonly used methods for in vivo MRS detection of γ-aminobutyric acid (GABA) is the MEGA-point-resolved spectroscopy (MEGA-PRESS) technique. However, accurate quantification of GABA using MEGA-PRESS is complicated by spectral co-editing of macromolecular resonances. In this article, a new pulse sequence is presented which enables GABA editing at 3T with the removal of macromolecule contamination. This sequence combines the conventional MEGA editing scheme with the SPECIAL localisation technique, and is therefore named MEGA-SPECIAL. Simulations and phantom experiments indicate that this new approach provides improved GABA editing efficiency relative to MEGA-PRESS, and in vivo results demonstrate effective removal of macromolecule contamination. In a study of the occipital lobe of five healthy volunteers, the macromolecule-corrected GABA/creatine ratio was found to be 0.093 ± 0.007 (mean ± standard deviation), whereas prior to macromolecule correction, the ratio was found to be 0.173
GABA Release. Cerebral cortical neurons in culture were pre-loaded with [3H]GABA (1 μM, 0.1 μCi) for 30 min in the presence of 10 μM vigabatrin to irreversibly inactivate GABA-transaminase, thereby blocking GABA metabolism (Drejer et al., 1987; Gram et al., 1988). Individual cultures (35-mm Petri dishes) were subsequently placed in a superfusion apparatus (Drejer et al., 1987) at 37°C equipped with peristaltic pumps, and the cells were superfused at a flow rate of 2 ml/min. Fractions from the outlet were collected every 30 s, and at the end of the experiments, radioactivity was determined in all fractions. During the superfusion, either 200 μM nonradioactive GABA or 200 μM EF1502 was added to the superfusion medium for 2 min. Results were expressed as counts per minute per fraction collected. It should be noted that since the baseline of the GABA release during the entire superfusion period was constant no major loss of intracellular [3H]GABA occurred during this period.. Animals. Male ...

The complex organisation of central synapses offers multiple mechanisms for regulation and modulation of synaptic strength. We focus on inhibitory synapses in the mammalian CNS which use GABA (gamma-aminobutyric acid) as transmitter. The availability of GABA is regulated by its synthesis, degradation and after release-uptake. In situations of over-excitability, the GABA-synthetizing enzyme GAD is up-regulated while a decrease of neuronal activity leads to a down-regulation of GAD. Thus, cellular GABA content seems to be an activity-dependent, variable parameter. We propose that the presynaptic GABA metabolism is a true and autonomous mechanism of synaptic plasticity. We are presently testing this hypothesis using various electrophysiological, histological and biochemical techniques. ...

Alzheimers disease (AD) is characterized by the transition of amyloid-β (Aβ) monomers into toxic oligomers and plaques. Given that Aβ abnormality typically precedes the development of clinical symptoms, an agent capable of disaggregating existing Aβ aggregates may be advantageous. Here we report that a small molecule, 4-(2-hydroxyethyl)-1-piperazinepropanesulphonic acid (EPPS), binds to Aβ aggregates and converts them into monomers. The oral administration of EPPS substantially reduces hippocampus-dependent behavioural deficits, brain Aβ oligomer and plaque deposits, glial γ-aminobutyric acid (GABA) release and brain inflammation in an Aβ-overexpressing, APP/PS1 transgenic mouse model when initiated after the development of severe AD-like phenotypes ...

Aminooxyacetic acid, often abbreviated AOA or AOAA, is a compound that inhibits 4-aminobutyrate aminotransferase (GABA-T) activity in vitro and in vivo, leading to less gamma-aminobutyric acid (GABA) being broken down. Subsequently, the level of GABA is increased in tissues. At concentrations high enough to fully inhibit 4-aminobutyrate aminotransferase activity, aminooxyacetic acid is indicated as a useful tool to study regional GABA turnover in rats. Aminooxyacetic acid is a general inhibitor of pyridoxal phosphate (PLP)-dependent enzymes (this includes GABA-T). It functions as an inhibitor by attacking the Schiff base linkage between PLP and the enzyme, forming oxime type complexes. Aminooxyacetic acid inhibits aspartate aminotransferase, another PLP-dependent enzyme, which is an essential part of the malate-aspartate shuttle. The inhibition of the malate-aspartate shuttle prevents the reoxidation of cytosolic NADH by the mitochondria in nerve terminals. Also in the nerve terminals, ...
Succinic semialdehyde dehydrogenase deficiency (SSADHD), also known as 4-hydroxybutyric aciduria or gamma-hydroxybutyric aciduria, is a rare autosomal recessive disorder of the degradation pathway of the inhibitory neurotransmitter γ-aminobutyric acid, or GABA. The disorder has been identified in approximately 350 families, with a significant proportion being consanguineous families. The first case was identified in 1981 and published in a Dutch clinical chemistry journal that highlighted a person with a number of neurological conditions such as delayed intellectual, motor, speech, and language as the most common manifestations. Later cases reported in the early 1990s began to show that hypotonia, hyporeflexia, seizures, and a nonprogressive ataxia were frequent clinical features as well. SSADH deficiency is caused by an enzyme deficiency in GABA degradation. Under normal conditions, SSADH works with the enzyme GABA transaminase to convert GABA to succinic acid. Succinic acid can then be ...

Valproic Acid is an anticonvulsant and mood-stabilizing drug used primarily in the treatment of epilepsy and bipolar disorder. It is also used to treat migraine headaches and schizophrenia. In epileptics, valproic acid is used to control absence seizures, tonic-clonic seizures (grand mal), complex partial seizures, and the seizures associated with Lennox-Gastaut syndrome. Valproic Acid is believed to affect the function of the neurotransmitter GABA (as a GABA transaminase inhibitor) in the human brain. Valproic Acid dissociates to the valproate ion in the gastrointestinal tract. Valproic acid has also been shown to be an inhibitor of an enzyme called histone deacetylase 1 (HDAC1). HDAC1 is needed for HIV to remain in infected cells. A study published in August 2005 revealed that patients treated with valproic acid in addition to highly active antiretroviral therapy (HAART) showed a 75% reduction in latent HIV infection ...

Objective: To study cortical excitability, electroencephalography patterns, nerve conduction velocity, and sleep patterns, in succinic semialdehyde dehydrogenase (SSADH) deficiency, a rare autosomal recessive pediatric neurotransmitter disease associated with elevated levels of brain gamma aminobutyric acid (GABA), the major inhibitory neurotransmitter. The clinical phenotype includes mental retardation, epilepsy, and neuropsychiatric manifestations.. Study Population: Patients with SSADH deficiency, parents of patients (who are obligate heterozygotes), and healthy volunteers.. Design: This is a natural history study in which subjects will have a series of neurophysiological tests. Transcranial magnetic stimulation (TMS) is a non-invasive technique that allows for measures of cortical excitation and inhibition. Electroencephalography (EEG) measures baseline brain electrical activity. Nerve conduction studies measure the speed of conduction of impulses by peripheral nerves. Polysomnography ...
We show that expression of B. subtilis threonine deaminase, combined with expression of a mutated form of E. coli glutamate dehydrogenase leads to the production of 0.40 ± 0.02 mg/L of (S)-2-aminobutyric acid in shake flask-grown S. cerevisiae cells. The higher production in E. coli achieved by Zhang and co-workers [26] is perhaps due to the special properties of the E. coli strain employed, which can produce 8 g/L l-threonine from 30 g/L glucose. Nevertheless, we rationalize that yeast is indeed a superior production host for (S)-2-aminobutanol production, as it displays higher robustness and considerable tolerance against harsh fermentation conditions. Yeast is also more resistant towards exposure to (S)-2-aminobutanol (Additional file 1: Figure S4). Moreover, the fermentation of yeasts is easily implemented into existing ethanol productions plants, and there are no issues with phage contamination. S. cerevisiae is classified as GRAS (generally regarded as safe) organism; thereby further ...

GHB is thought to be extensively metabolized by alcohol dehydrogenase and/or succinic semialdehyde dehydrogenase. Metabolic precursors to GHB, gamma-butyrolactone (GBL) and 1,4 butanediol are also readily available as substances of abuse. Endogenous GHB is also a produce to GABA metabolism, and concentrations of 0-6.6 mg/L have been reported. Oral doses of approximately 2.5 g (1 teaspoon of GHB powder) dissolved in water, produce urine GHB concentrations of 29 mg/L in a 100 kg man.. Studies also indicate peak urine GHB concentrations of 100 mg/L following a 100 mg/kg oral dose, and no detectable drug in the urine by 12 hours. Less than 5% of an oral dose is eliminated unchanged in urine. To distinguish between endogenous and exogenous GHB, a reporting cutoff of 10 µg/mL is suggested.. How do I collect the urine and send in a specimen? ...
RESULTS: The GABA signalling system was compromised in islets from type 2 diabetic individuals, where the expression of the genes encoding the α1, α2, β2 and β3 GABA(A) channel subunits was downregulated. GABA originating within the islets evoked tonic currents in the cells. The currents were enhanced by pentobarbital and inhibited by the GABA(A) receptor antagonist, SR95531. The effects of SR95531 on hormone release revealed that activation of GABA(A) channels (GABA(A) receptors) decreased both insulin and glucagon secretion. The GABA(B) receptor antagonist, CPG55845, increased insulin release in islets (16.7 mmol/l glucose) from normoglycaemic and type 2 diabetic individuals ...

Vigabatrin official prescribing information for healthcare professionals. Includes: indications, dosage, adverse reactions, pharmacology and more.
So, we now have to make a decision between two drugs. One drug is the ACTH steroid. ACTH is FDA approved (and covered by insurance), begins in the hospital, is an injection that must be given twice a day for 6 weeks, has serious, life threatening side effects (including decreased immune system) and has a 50% chance of working. Once treatment begins, well know within 2 weeks if it is working, and if it stops her seizures, she is done with the drug in 6 weeks and may never need it again, unless she has a relapse. The side effects are reversible. The other drug is called Vigabatrin (Sabril) which is not FDA approved and must be obtained in either Canada or Mexico. Vigabatrin comes in pill form, and does not have the severe side effects associated with ACTH (including the fact that it will not alter her immune system, and she does not need hospitalization.) Vigabatrin has been in use everywhere except the US for 10 years, and has not been approved by the FDA because there is a report that some ...

Prvi dan v tednu je bil Saturnov dan, kateremu so sledili Sončev, Lunin, Marsov, Merkurjev, Jupitrov in Venerin dan. Domneva se, da se je astrološki dan začel s sončnim vzhodom. Sedemdnevni koledar, ki se je začenjal v soboto zvečer, so uporabljali tudi Judje. Sedmi dan v tednu se je imenoval šabat, druge dneve v tednu pa so številčili. Izjema je bil petek, ki se je imenoval parasceve (priprava) ali šesti dan. Judovski dnevi so se začenjali s sončnim zahodom. Kristjani so privzeli judovski sedemdnevni teden. Prvi dan v tednu je bila Dominica ali Gospodov dan. Konstantin Veliki je v čast Neosvojenega sonca, varuha svoje družine, leta 321 nedeljo razglasil za dela prost dan, s čimer je v rimsko družbo uvedel ...
