Effect of acute and chronic stress on memory impairment and hippocampal oxidative stress following global cerebral ischemia in adult male rats.
Article in Research in pharmaceutical sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Background and purpose: Stress, especially immobility stress, is quite common and one of the most important and influential risk factors in neurological disorders. This study aimed to investigate the effect of acute and chronic immobility stress on the level of cortical and hippocampal oxidative stress indicators and memory impairment following global cerebral ischemia. Experimental approach: In this study, 48 male Wistar rats were randomly divided into 6 groups: 1, sham (S); 2, sham-acute stress (SSA); 3, sham-chronic stress (SSC); 4, ischemia (IS); 5, ischemia-acute stress (ISA); 6, ischemia-chronic stress (ISC). The Morris water maze (MWM) test was performed 14 days after surgery, and cortisol levels and oxidative stress factors such as malondialdehyde MDA and total thiol were measured. Findings/Results: In the MWM test, the time to find the platform (latency time) in the ISC and IS groups significantly increased compared to the S group. The time spent in the target quarter in these two groups was significantly reduced compared to the S group on the day of the probe. The results showed a significant increase in cortisol levels and malondialdehyde concentration in the ISA, ISC, and IS groups compared to the S group, but there was no significant difference in total thiol concentration. No significant difference was observed in the level of oxidative stress factors in the cortex. Conclusion and implication: Chronic immobility stress could reduce antioxidant factors in the hippocampus and exacerbate memory impairment caused by global ischemia.
