Rosa davurica Pall. as a Functional Food in Ameliorating Acute Myocardial Ischemia: An Integrated Multi-Omics Study on TNF-α and Oxidative Stress.
Article in Chemistry & biodiversity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Rosa davurica Pall. (RDP), a rosa fruit rich in bioactive compounds, has shown potential in alleviating cardiovascular diseases, yet its chemical composition and mechanisms against acute myocardial ischemia (AMI) remain unclear. This study comprehensively characterized 99 compounds in RDP extracts using ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS), including flavonoids, terpenoids, and phenolic acids. By integrating transcriptomics and network pharmacology, we identified the tumor necrosis factor-alpha (TNF-α) signaling pathway as a key target in AMI progression. In vivo experiments demonstrated that RDP significantly ameliorated isoproterenol (ISO)-induced myocardial injury by reducing oxidative stress and suppressing the release of inflammatory cytokines (IL-6, IL-2, IL-17). Molecular docking and dynamics simulations further revealed that bioactive components in RDP, such as rutin and hyperoside, effectively bind to TNF-α and its receptor TNF receptor 1 (TNFR1), thereby modulating inflammatory responses. These findings provide valuable insights into the multi-target cardioprotective effects of RDP, supporting its application as a promising functional food.
