Acute continuous nocturnal light exposure decreases BSR under sevoflurane anesthesia in C57BL/6J mice: possible role of differentially spared light-sensitive pathways under anesthesia.

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
Brain responses to external stimuli such as light are preserved under general anesthesia. In nocturnal animals, acute light exposure can induce sleep, and acute dark can increase wakefulness. This study aims to investigate the effect of acute continuous nocturnal light exposure (ACNLE) on burst-suppression patterns under sevoflurane anesthesia using electroencephalogram (EEG) monitoring in mice. We set the initial sevoflurane dose to 2.0% and increased it by 0.5% every 20 min until it reached 4.0%. Burst-suppression ratio (BSR), EEG power and quantitative burst analysis were used to assess the effects of ACNLE on burst suppression patterns under sevoflurane anesthesia. Blood serum corticosterone measurement and c-Fos immunofluorescent staining of the suprachiasmatic nucleus (SCN) and ventrolateral preoptic nucleus (VLPO) were used to demonstrate the biological consequence induced by ACNLE. Compared to darkness, ACNLE caused significant changes in EEG power and decrease of BSR at 2.5%, 3.0% and 3.5% sevoflurane. ACNLE was also associated with an increase in burst duration and burst frequency as well as a decrease in burst maximum peak-to-peak amplitude and burst power in the beta (15-25 Hz) and gamma (25-80 Hz) bands. ACNLE increased the concentration of serum corticosterone and the expression of c-Fos in the SCN, while not changed c-Fos expression in the VLPO. These results demonstrated that ACNLE influences the BSR under sevoflurane anesthesia, possibly by activating light-sensitive nonvisual pathways including SCN and increasing of peripheral serum corticosterone levels.
