Glutamate neurocircuitry: theoretical underpinnings in schizophrenia

open access: yesFrontiers in Pharmacology, 2012
The Dopamine Hypothesis of Schizophrenia is actively being challenged by the NMDA Receptor Hypofunctioning Hypothesis of Schizophrenia. The latter hypothesis may actually be the starting point in neuronal pathways that ultimately modifies dopamine ...

Biological Sources of Inflexibility in Brain and Behavior with Aging and Neurodegenerative Diseases

open access: yesFrontiers in Systems Neuroscience, 2012
Almost unequivocally, aging and neurodegeneration lead to deficits in neural information processing. These declines are marked by increased neural noise that is associated with increased variability or inconsistency in behavioral patterns.

Surface grafting of poly (L-glutamates). 1. Synthesis and characterization

open access: yes, 2001
The ring-opening polymerization of N-carboxyanhydrides (NCA) of γ-benzyl l-glutamate and γ-methyl l-glutamate from (γ-aminopropyl)triethoxysilane (APS) pretreated substrates such as silicon wafers and quartz slides was investigated.

A study of genetic heterogeneity in autism spectrum disorders based on plasma proteomic and metabolomic analysis: multiomics study of autism heterogeneity

open access: yesMedComm, 2023
Genetic heterogeneity poses a challenge to research and clinical translation of autism spectrum disorder (ASD). In this study, we conducted a plasma proteomic and metabolomic study of children with ASD with and without risk genes (de novo mutation) and ...

Surface grafting of poly(L-glutamates). 2. Helix orientation

open access: yes, 2001
In this paper the average helix orientation of surface-grafted poly(γ-benzyl l-glutamate) (PBLG), poly(γ-methyl l-glutamate) (PMLG), and poly(γ-methyl l-glutamate)-co-(γ-n-stearyl l-glutamate) (PMLGSLG 70/30) was investigated by means of FT-IR ...

QM/MM study of the stereospecific proton exchange of glutathiohydroxyacetone by glyoxalase I

open access: yesResults in Chemistry, 2019
We have performed quantum mechanics (QM), molecular mechanics (MM) and hybrid QM/MM calculations to study the stereospecific proton exchange of glutathiohydroxyacetone (HOC-SG) by glyoxalase I (GlxI). We did the QM/MM calculations with a large QM system (

Magnetic resonance imaging in studying schizophrenia, negative symptoms and the glutamate system

open access: yesFrontiers in Psychiatry, 2014
Schizophrenia is characterized by positive, negative and cognitive symptoms. While positive symptoms occur periodically during psychotic exacerbations, negative and cognitive symptoms often emerge before the first psychotic episode and persist with low ...

What does the mediodorsal thalamus do?

open access: yesFrontiers in Systems Neuroscience, 2013
Dense amnesia can result from damage to the medial diencephalon in humans and in animals. In humans this damage is diffuse and can include the mediodorsal nuclei of the thalamus.
