Ozone controls the metabolism of tryptophan protecting against sepsis-induced intestinal damage by activating aryl hydrocarbon receptor.

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
backgroundIntestinal injury is the most common complication of sepsis, and the mitigation of intestinal damage is crucial for treating sepsis.
aimTo examine the use of ozone-rich water and its action in preventing intestinal damage caused by sepsis.
methodsThrough histological analysis, immunohistochemistry, immunofluorescence assays, and Western blot detection, we evaluated the therapeutic efficacy of ozone in mitigating intestinal injury during sepsis. Additionally, by conducting 16S rRNA sequencing and untargeted metabolomics analysis on fecal samples, we identified alterations in the gut microbiota and specific metabolites in septic mice following ozone treatment. This comprehensive approach aims to further elucidate the mechanistic underpinnings of ozone therapy in alleviating sepsis-induced intestinal damage.
resultsOur results demonstrate that ozonated water significantly ameliorates pathological damage in intestinal tissues, enhances the expression of tight junction proteins, and inhibits the polarization of intestinal macrophages, thereby reducing the expression of inflammatory cytokines in intestinal tissues of cecal ligation and puncture-induced septic mice. 16S rRNA sequencing analysis revealed that ozonated water increased the abundance of beneficial bacteria and alleviated gut microbiota dysbiosis. Studies using broad-spectrum antibiotic-treated mice indicated that the protective effects of ozonated water on intestinal injury are dependent on the gut microbiota. Furthermore, metabolomic analysis identified an increase in the tryptophan metabolite DL-tryptophan in the ozonated water treatment group. This suggests that ozonated water protects against intestinal injury by activating the aryl hydrocarbon receptor and suppressing necroptosis in intestinal epithelial cells.
conclusionOzone protected against sepsis-induced intestinal injury through regulation of the gut microbiota and tryptophan metabolism, inhibiting necrotic apoptosis of intestinal epithelial cells through activation of the aryl hydrocarbon receptor.
