Distinct amygdalar AMPAergic/GABAergic mechanisms promote anxiolitic-like effects in an unpredictable stress model of the hamster.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Studies have pointed to both α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptor (AMPAR) antagonists and GABA(A) receptor (GABA(A)R) agonists as potent antistress agents. In this work, separate subchronic injections of the AMPAR antagonist, 6-ciano-7-nitroquinoxaline-2,3-dione (CNQX), and α1 GABA(A)R subunit agonist (Zol) within the central amygdala nucleus modified the elevated plus maze performances of hamsters exposed randomly to one of the following stressful conditions: food/water deprivation, forced swimming test, and permanence in cold room. Indeed, stressed hamsters treated with CNQX or Zol displayed a very great (p < 0.001) increase of entrance plus a moderate (p < 0.05) time spent into open arms, respectively. At the cellular level, Zol-treated animals supplied a moderately evident argyrophilic reaction (indicative of neurodegeneration) in the hippocampus while it was absent in the hypothalamus. Interestingly, this reaction was significantly reduced by CNQX supporting its preferential protective role. Furthermore, both agents were responsible for a mixed expression pattern of GluR1 and GluR2 mRNA levels in which Zol overall upregulated GluR1 mRNAs, while they were downregulated by CNQX in the hippocampal oriens-pyramidalis layer and in layer III of the cerebral cortex. These findings support the amygdalar AMPAergic protective response against anxiety states in chronically stressed hamsters, which may constitute useful therapeutic strategies for panic-related mood disorders.
