The effects of d-cycloserine (DCS), a N-methyl-d-aspartate receptor-associated glycine site
agonist, and milacemide (MIL), a glycine prodrug, were examined on learning impairments …

Substantial evidences suggest that the increased cerebral deposition, and neurotoxic action
of the β-amyloid peptide, the major constituent of senile plaques, may represent the …

The N-methyl-D-aspartate receptor complex appears to play an important role in processes
of learning and memory. The presence of a glycine modulatory site at this complex has …

The anti-amnesic effects of dynorphins on β-amyloid peptide-(25–35)-induced impairment of
learning and/or memory in mice were investigated using a Y-maze task and a passive …

Aggregated 40-residue amyloid-β peptide (β40, 4 μg/μl), and 2 days later, ibotenate (NMDA
receptor agonist, 0.3 μg/0.5 μl), were bilaterally injected into the hippocampus of rats. Five to …

Glycine has been shown to modulate N-methyl-D-aspartate (NMDA) subclass of acidic
amino acid receptors which have been implicated in learning and memory. We report that d …

Amyloid beta fragment 25-35 (Aβ25-35) is the neurotoxic domain of the full-length Aβ1-42
and causes memory impairments in rodents. Recent research suggests that agmatine …

The role of N-methyl-d-aspartate (NMDA) receptors in memory processes was examined
using a Y-shaped maze and a step-through passive avoidance task in mice. In the Y-maze …

In this study, we investigated the effects of both N-methyl D-aspartate (NMDA) and MK-801
on WIN55, 212-2 (WIN)-induced amnesia in rats. Step-through inhibitory avoidance of …

The sigma1 (σ1) receptor agonists exert potent anti-amnesic effects, as they apparently
block the learning impairments either induced by the muscarinic receptor antagonist …
