1 · What the graph read from it

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.

2 · The registry

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 pesticide chlorpyrifos (CPF) poses significant environmental and health risks due to its toxicity. Selenium nanoparticles (Se NPs) exhibit promising therapeutic properties. This study evaluated the effects of Se NPs against CPF hepatotoxicity, focusing on oxidative and inflammatory responses, and the SIRT1/FXR/Nrf2 pathway. Rats were exposed to CPF (5.4 mg/kg body weight), with or without Se NPs (0.5 mg/kg body weight), for 28 days, followed by biochemical, histopathological, and molecular analyses. CPF administration significantly increased serum ALT and AST, reduced albumin, and induced histopathological alterations. Se NPs effectively ameliorated liver function biomarkers and mitigated histopathological changes. CPF also elevated malondialdehyde and nitric oxide, and depleted enzymatic antioxidants and GSH, which were mitigated by Se NPs. CPF upregulated NF-κB p65, TNF-α, IL-6, iNOS, Bax and caspase-3, and downregulated Bcl-2. Se NPs suppressed inflammation and apoptosis by downregulating NF-κB p65, pro-inflammatory cytokines and pro-apoptosis markers. These effects were linked to upregulation of SIRT1, FXR, Nrf2 and HO-1 and suppression of Keap1. In conclusion, Se NPs protect against CPF-induced liver injury by attenuating OS, inflammation, and apoptosis, and by upregulating SIRT1//FXR/Nrf2 signaling. These findings highlight the therapeutic potential of Se NPs in mitigating hepatotoxicity induced by exposure to CPF.
