Analysis of polyunsaturated fatty acids and the omega-6 inflammatory pathway in hepatic ischemia/re-perfusion injury.
Article in Molecular medicine reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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 aim of the present study was to assess omega-3 (n-3) and omega-6 (n-6) polyunsaturated fatty acids (PUFAs) in liver tissue and evaluate changes in the n‑6-associated inflammatory pathway following liver ischemia/re‑perfusion (IR) injury. Male Wistar rats which were allowed free access to standard rat chow were included in the study. Blood vessels supplying the median and left lateral hepatic lobes were occluded with an arterial clamp for 60 min, followed by 60 min of re‑perfusion. Levels of arachidonic acid (AA, C20:4n‑6), dihomo‑gamma‑linolenic acid (DGLA, C20:3n‑6), eicosapentaenoic acid (EPA, C20:5n‑3) and docosahexaenoic acid (DHA, C22:6n‑3) in liver tissue were determined by an optimized multiple reaction monitoring method using ultra fast‑liquid chromatography coupled with tandem mass spectrometry. Phospholipase A2 (PLA2), cyclooxygenase (COX) and prostaglandin E2 (PGE2) were measured in tissue samples to evaluate changes in the n‑6 inflammatory pathway. Total histopathological score of cellular damage were significantly increased following hepatic IR injury. n‑3 and n‑6 PUFA levels were significantly increased in post‑ischemic liver tissue compared to those in non‑ischemic controls. No significant difference was observed in the AA/DHA and AA/EPA ratio in post‑ischemic liver tissues compared with that in the control. Tissue activity of PLA2 and COX as well as PGE2 levels were significantly increased in post‑ischemic liver tissues compared to those in non‑ischemic controls. The results of the present study suggested that increased hydrolysis of fatty acids via PLA2 triggers the activity of COX and leads to increased PGE2 levels. Future studies evaluating agents which block the formation of eicosanoids derived from n‑6 PUFAs may facilitate the development and application of treatment strategies in liver injury following IR.
