Lymph-Targeted Resveratrol-NLCs Improve Oral Bioavailability: Validation via Rat Mesenteric Lymph Collection System and In Vivo Safety.
Article in Animals : an open access journal from MDPI, 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
Resveratrol (RES) is a natural polyphenolic compound characterized by poor aqueous solubility and significant first-pass metabolism, resulting in extremely low oral bioavailability. Although resveratrol-loaded nanostructured lipid carriers (RES-NLCs) have shown potential in enhancing oral absorption, direct experimental evidence for their intestinal lymphatic transport mechanism remains limited, and existing explanations is largely based on indirect inference. RES-NLCs were prepared, and their pharmacokinetics and lymphatic transport characteristics were evaluated using a laboratory-established mesenteric lymph duct-jugular vein assisted reflux model in rats. Simultaneously, a 28-day repeated-dose toxicity study was conducted in ICR mice. Pharmacokinetic results showed that compared with RES-Sol, RES-NLCs increased Cmax by approximately 2.3-fold, improved relative bioavailability by 7-fold, and achieved an absolute bioavailability of 176%. The lymphatic transport model confirmed that RES-NLCs are absorbed via the intestinal lymphatic pathway. In the 28-day repeated-dose toxicity study, no mortality or obvious clinical symptoms were observed at a dose of 10 mg/kg. The RES-NLCs group exhibited increased liver coefficient and decreased spleen coefficient. Hematological analysis showed a mild increase in red blood cell count, along with decreases in mean corpuscular volume and red blood cell distribution width coefficient of variation. Serum biochemistry revealed significant elevations in aspartate aminotransferase and alanine aminotransferase (
