Gamma-aminobutyric acid mediates nicotine biosynthesis in tobacco under flooding stress

Plant Diversity, 2016
Gamma-aminobutyric acid (GABA) is a four-carbon non-protein amino acid conserved from bacteria to plants and vertebrates. Increasing evidence supports a regulatory role for GABA in plant development and the plant's response to environmental stress.

The general anaesthetic etomidate inhibits the excitability of mouse thalamocortical relay neurons by modulating multiple modes of GABA_A receptor-mediated inhibition [PDF]

, 2014
Modulation of thalamocortical (TC) relay neuron function has been implicated in the sedative and hypnotic effects of general anaesthetics. Inhibition of TC neurons is mediated predominantly by a combination of phasic and tonic inhibition, together with a

The Factors of the Classification of Protein Amino Acids [PDF]

This paper is published in GLASNIK of Montenegrin Academy of Science and arts, 2000, 13, pp. 173-194, 2006
In this work it is shown that three pairs of the factors appear to be the key, i.e. main factors of a natural classification of protein (canonical) amino acids within the amino acid (genetic) code. First pair: the factors of the habit of an amino acid molecule (size and polarity).

GABAergic modulation of beta power enhances motor adaptation in frontotemporal lobar degeneration

Alzheimer's &Dementia, EarlyView.
Abstract INTRODUCTION We examined how abnormal prefrontal neurophysiology and changes in gamma‐aminobutyric acid‐ergic (GABAergic) neurotransmission contribute to behavioral impairments in disorders associated with frontotemporal lobar degeneration (FTLD). METHODS We recorded magnetoencephalography during an adaptive visuomotor task from 11 people with

Insights into GABA receptor signalling in TM3 Leydig cells [PDF]

, 2005
gamma-Aminobutyric acid (GABA) is an emerging signalling molecule in endocrine organs, since it is produced by endocrine cells and acts via GABA(A) receptors in a paracrine/autocrine fashion.

Resolution, quantification, and reliable determination of enantiomeric excess of proteinogenic and non‐proteinogenic amino acids by comprehensive two‐dimensional gas chromatography

Journal of Separation Science, Volume 45, Issue 24, Page 4416-4426, December 2022., 2022
This work proposes a comprehensive two‐dimensional gas chromatography method for the resolution and quantification of 27 amino acids, including 17 enantiomeric pairs, as stable N‐trifluoroacetyl‐O‐methyl ester derivatives. The derivatization approach in combination with enantioselective two‐dimensional gas chromatography has proven to be highly ...

Lack of evidence for central sensitization in idiopathic, non-traumatic neck pain : a systematic review [PDF]

, 2015
Background: Chronic neck pain is a common problem with a poorly understood pathophysiology. Often no underlying structural pathology can be found and radiological imaging findings are more related to age than to a patient's symptoms.

Modeling of the formation of short-chain acids in propane flames [PDF]

arXiv, 2009
In order to better understand their potential formation in combustion systems, a detailed kinetic mechanism for the formation of short-chain monocarboxylic acids, formic (HCOOH), acetic (CH3COOH), propionic (C2H5COOH) and propenic (C2H3COOH)) acids, has been developed. Simulations of lean (equivalence ratios from 0.9 to 0.48) laminar premixed flames of

Discovery Of Copper Catalyst For New Chemical Polishing Acid On Superconducting Niobium [PDF]

arXiv, 2020
High field Q-slope (HFQS) seriously limits the high gradient performance of the buffered chemically polished (BCP) superconducting radio frequency (SRF) niobium cavities. The direct cause or mechanism is not yet fully understood. In our recent extensive data analysis, we concluded that the potential root cause could be nitrogen contamination on the ...

A thermodynamic basis for prebiotic amino acid synthesis and the nature of the first genetic code [PDF]

, 2009
Of the twenty amino acids used in proteins, ten were formed in Miller's atmospheric discharge experiments. The two other major proposed sources of prebiotic amino acid synthesis include formation in hydrothermal vents and delivery to Earth via meteorites.
