Is Lipopolysaccharide-Induced Lipid Metabolism Disorder in Testis of Rats a Consequence of Plasma Lipid Changes?

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
Purpose: The systemic infection and inflammation can result in testes injury, whereas the exact mechanism is unknown. The lipid metabolism has a dual impact on controlling metabolism and inflammation, which is a potential pathway. The objective of this study was to determine if changes in plasma lipids during lipopolysaccharide (LPS)-induced systemic inflammation affect the dysregulation of testes lipid metabolism. Materials and Methods: LPS (5 mg/kg) was used to induce systemic inflammation in rats after a single intraperitoneal injection. After 4 weeks, the rats were sacrificed, and the serum and testes were used for laboratory measurements and histology examination. Plasma and testis were used for lipidomics analysis based the liquid chromatography-mass spectrometry. Spearman rank correlation analysis was used to compare the correlation of differential lipids in phospholipids, glycerolipids, and sphingolipids between testis and plasma. Results: LPS raised the levels of cytokines in serum and testis, decreased the activities of antioxidant enzymes, increased the levels of lipid peroxidation products, and damaged testis tissue. In testis and plasma, 146 and 401 differential lipids, mostly phosphatidylcholine, phosphatidylethanolamine an so on, were found in comparison to the control group. Correlation analysis produced a total of 2528 correlation coefficients, 1150 of which were P<0.05 and accounted for 45.49%. Conclusion: The changes of lipid composition and content in the testis are related to cytokine overload and oxidative stress. Testis lipid metabolism disorders caused by LPS-induced systemic inflammation are lack of a correlation with plasma lipid changes, and are likely owing to interference with the testis itself.
