Glutamate Taste: Discrimination between the Tastes of Glutamate Agonists and Monosodium Glutamate in Rats [PDF]

open access: yesChemical Senses, 2004
Taste aversion studies have demonstrated that rats conditioned to avoid monosodium glutamate (MSG) with amiloride added to reduce the intensity of the sodium component of MSG taste, generalize this aversion to aspartic acid and to L-AP4, but not to ionotropic glutamate receptor agonists.

Re‐evaluation of glutamic acid (E 620), sodium glutamate (E 621), potassium glutamate (E 622), calcium glutamate (E 623), ammonium glutamate (E 624) and magnesium glutamate (E 625) as food additives

open access: yesEFSA Journal, 2017
The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) provides a scientific opinion re‐evaluating the safety of glutamic acid–glutamates (E 620–625) when used as food additives.

Increased accuracy of ligand sensing by receptor diffusion on cell surface [PDF]

open access: yesPhysical Review E 82, 041902 (2010), 2010
The physical limit with which a cell senses external ligand concentration corresponds to the perfect absorber, where all ligand particles are absorbed and overcounting of same ligand particles does not occur. Here we analyze how the lateral diffusion of receptors on the cell membrane affects the accuracy of sensing ligand concentration.

Molecular Cloning and Characterization of SaCLCd, SaCLCf, and SaCLCg, Novel Proteins of the Chloride Channel Family (CLC) from the Halophyte Suaeda altissima (L.) Pall

open access: yesPlants, 2022
Coding sequences of the CLC family genes SaCLCd, SaCLCf, and SaCLCg, the putative orthologs of Arabidopsis thaliana AtCLCd, AtCLCf, and AtCLCg genes, were cloned from the euhalophyte Suaeda altissima (L.) Pall.

Modulation of synaptic plasticity by glutamatergic gliotransmission: A modeling study [PDF]

open access: yesNeural Plasticity, volume 2016 (2016), Article ID 7607924, 2016
Glutamatergic gliotransmission, that is the release of glutamate from perisynaptic astrocyte processes in an activity-dependent manner, has emerged as a potentially crucial signaling pathway for regulation of synaptic plasticity, yet its modes of expression and function in vivo remain unclear.

Glutamate transporter control of ambient glutamate levels

open access: yesNeurochemistry International, 2014
Accurate knowledge of the ambient extracellular glutamate concentration in brain is required for understanding its potential impacts on tonic and phasic receptor signaling. Estimates of ambient glutamate based on microdialysis measurements are generally in the range of ∼2-10μM, approximately 100-fold higher than estimates based on electrophysiological ...

Phosphine Catalyzed Michael-Type Additions: The Synthesis of Glutamic Acid Derivatives from Arylidene-α-amino Esters

open access: yesMolecules
The reaction of arylidene-α-amino esters with electrophilic alkenes to yield Michael-type addition compounds is optimized using several phosphines as organocatalysts. The transformation is very complicated due to the generation of several final compounds,

Synthesis of N -(4-propargylaminobenzoyl)-L-glutamates

open access: yesPteridines, 1994
To facilitate the rather labour consuming synthesis of antifolate γ-oligo-L-glutamates including those with the propargyl group at position N10 , two synthons possessing this group, α-t-butyl γ-methyl N-(4-propargylaminobenzoyl)- L-glutamate (1) and a-t ...

Epitope-tagged and phosphomimetic mouse models for investigating natriuretic peptide-stimulated receptor guanylyl cyclases

open access: yesFrontiers in Molecular Neuroscience, 2022
The natriuretic peptide receptors NPR1 and NPR2, also known as guanylyl cyclase A and guanylyl cyclase B, have critical functions in many signaling pathways, but much remains unknown about their localization and function in vivo. To facilitate studies of

Pharmacotherapy of Schizophrenia: Ploypharmacy Approaches [PDF]

open access: yesActa Medica Iranica, 2010
Schizophrenia is a debilitating illness, rating as one of the leading causes of lost years of quality of life. The illness imposes a disproportionate burden on patients and their families, healthcare systems and society. Pharmacological management is the
