The impact of modafinil on memory and brain oxidative stress: contrasting effects of acute and chronic administration in healthy rats.

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
The present study assessed the impact of modafinil (MD) on memory function and oxidative damage in the brains of naive rats. Wistar rats were administered either a single dose or repeated doses (over 30 days) of water or MD (75, 150, or 300 mg/kg) via gavage. The novel object recognition (NOR), open-field habituation (OFH), and inhibitory avoidance task (IA) tested the animals' memory. Furthermore, the oxidative and nitrosative stress markers (4-hydroxynonenal [4-HNE], 8-isoprostane [8-ISO], 3-nitrotyrosine [3-nitro], superoxide dismutase [SOD], and catalase [CAT]) were assessed in the frontal cortex, hippocampus and striatum of the rats. The acute administration of MD did not affect any memory measures or oxidative stress parameters evaluated in this study. In contrast, chronic MD administration at a dose of 300 mg/kg decreased memory related to habituation and recognition. In addition, chronic administration of this drug increased oxidative lipid damage, evaluated through 8-ISO and 4-HNE. These findings suggest a potential link between chronic MD use, memory impairment, and oxidative stress in the brains of rats, emphasizing the importance of further research in this area.
