1. Does mismatch negativity have utility for NMDA receptor drug development in depression?
Rapid antidepressant effects associated with ketamine have shifted the landscape for the development of therapeutics to treat major depressive disorder (MDD) from a monoaminergic to glutamatergic model. Treatment with ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, may be effective, but has many non-glutamatergic targets, and clinical and logis

2. The role of NMDA receptor antagonists, amantadine and memantine, in schizophrenia treatment: a systematic review
Abstract Objective Schizophrenia is a complex and chronic psychiatric disorder. In recent years, studies have found glutamatergic system participation in its etiopathogenesis, especially through aberrant NMDA receptors functioning. Thus, drugs that modulate this activity, as amantadine and memantine, could theoretically be used in its treatment. To perform

3. Antinociceptive effect of PnTx4(5-5), a peptide from Phoneutria nigriventer spider venom, in rat models and the involvement of glutamatergic system
ABSTRACT Background: The venom of Phoneutria nigriventer spider is a source of numerous bioactive substances, including some toxins active in insects. An example is PnTx4(5-5) that shows a high insecticidal activity and no apparent toxicity to mice, although it inhibited NMDA-evoked currents in rat hippocampal neurons. In this work the analgesic activity o

4. Assessment of neuropharmacological potential of low molecular weight components extracted from Rhinella schneideri toad poison
Abstract Background: Studies on toad poison are relevant since they are considered a good source of toxins that act on different biological systems. Among the molecules found in the toad poison, it can be highlighted the cardiotonic heterosides, which have a known mechanism that inhibit Na+/K+-ATPase enzyme. However, these poisons have many other molecules

5. Terapêutica anestésica para o alívio da dor aguda pós-colecistectomia videolaparoscópica: revisão sistemática.
RESUMO A terapêutica inadequada da dor pós-operatória em colecistectomia videolaparoscópica pode levar a mobilização tardia, insatisfação do paciente, atraso na alta hospitalar e desenvolvimento de dor crônica. Objetivou-se identificar qual a melhor estratégia terapêutica disponível ao anestesiologista na terapia da dor aguda pós-operatória de

6. Potential antidepressant effect of amantadine: a review of preclinical studies and clinical trials
Objective: Amantadine blocks N-methyl-D-aspartate (NMDA) receptors and has dopaminergic and noradrenergic action, a neurochemical profile that suggests its potential as an antidepressant drug. We conducted a systematic review of preclinical and clinical studies addressing the effects of amantadine in animal models of depression and in patients with depressi

7. Anestesia em encefalite antirreceptor de N-metil-D-aspartato - a anestesia geral é um requisito? Relato de caso
Resumo A encefalite antirreceptor de N-metil-D-aspartato (NMDA) é um distúrbio neurológico recentemente descrito e uma causa cada vez mais reconhecida de psicose, distúrbios do movimento e disfunção autonômica. Relatamos o caso de uma paciente de origem chinesa, de 20 anos, que se apresentou com crises tônico-clônicas generalizadas, perda de memóri

8. In silico analysis of binding interaction of conantokins with NMDA receptors for potential therapeutic use in Alzheimer’s disease
Abstract Background The N-methyl-D-aspartate (NMDA) receptors are glutamate receptors that play vital roles in central nervous system development and are involved in synaptic plasticity, which is an essential process for learning and memory. The subunit N-methyl D-aspartate receptor subtype 2B (NR2B) is the chief excitatory neurotransmitter receptor in the

9. A Mechanism Study of NMDAR1 in A Rat Alzheimer Disease (AD) Model
ABSTRACT This study aimed to investigate the expression and mechanism of N- methyl -D- aspartate receptor 1 (NMDAR1) in the pathogenesis of Alzheimer disease (AD). Eighty adult Wistar rats were randomly divided into 4 groups (n=20 each) to receive an injection of 0, 5, 7 and 10 μl of 1 μg/μl amyloid-β 42 (Aβ1-42) in the hippocampus. Twenty rats in norma

10. Is Forced Swimming Immobility a Good Endpoint for Modeling Negative Symptoms of Schizophrenia? - Study of Sub-Anesthetic Ketamine Repeated Administration Effects
ABSTRACT Immobility time in the forced swimming has been described as analogous to emotional blunting or apathy and has been used for characterizing schizophrenia animal models. Several clinical studies support the use of NMDA receptor antagonists to model schizophrenia in rodents. Some works describe the effects of ketamine on immobility behavior but there

11. Simvastatin treatment reduces the cholesterol content of membrane/lipid rafts, implicating the N -methyl-D-aspartate receptor in anxiety: a literature review
ABSTRACT Membrane/lipid rafts (MLRs) are plasmalemmal microdomains that are essential for neuronal signaling and synaptic development/stabilization. Inhibitors of 3-hydroxy-3-methylglutaryl-coenzyme-A reductase (statins) can disable the N-methyl-D-aspartate (NMDA) receptor through disruption of MLRs and, in turn, decrease NMDA-mediated anxiety. This hypothes

12. Expressão do receptor de NMDA e do microRNA-129 em ratos submetidos à isquemia cerebral associada ao alcoolismo
RESUMO Algumas condições podem agravar os danos causados pelo processo isquêmico, tais como o consumo de álcool, e diversos mecanismos moleculares que estão envolvidos na fisiopatologia da isquemia cerebral, incluindo a expressão de neurotransmissores, e estes podem estar regulados por microRNAs. Objetivo: Avaliar a expressão de NMDA e do microRNA-21
