Protective Effects of Quercetin and Sucrose on Cold Preservation Injury in Porcine Kidneys Donated After Cardiac Death.

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
BACKGROUND The University of Wisconsin (UW) solution is the gold standard for kidney preservation. Quercetin (QE), a widely used flavonoid, possesses strong antioxidant, anti-inflammatory, and anti-apoptotic properties. Sucrose (Suc) has shown beneficial effects as a supplement. The aim of this study was to investigate the protective effects of QE and Suc against cold injury in porcine kidneys and to evaluate whether their use improves ischemia-reperfusion (I/R) injury after simple CS. MATERIAL AND METHODS Kidney grafts were procured after 30 min of warm ischemia, followed by preservation under 2 conditions for 22 h: Group 1, preserved with CS/UW solution (n=4), and Group 2, preserved with CS/UW solution containing QE 33.1 μM and Suc 0.1 M (n=6). All grafts were evaluated using an ex vivo isolated kidney reperfusion model with oxygenated, diluted autologous blood at room temperature. RESULTS At the end of reperfusion, creatinine phosphokinase and lactate dehydrogenase levels were significantly lower in Group 2 than in Group 1. We observed more vacuolation in the tubular epithelial cell in Group 1 than in Group 2, and the tubular epithelium showed more irregularity and exfoliation in Group 1 than in Group 2. Additionally, Group 2 had a significantly higher number of anti-ERG-positive endothelial cell nuclei than Group 1 at the end of reperfusion. CONCLUSIONS Our results suggest that the addition of QE and Suc to UW solutions can effectively prevent cold injury in DCD kidneys, with QE exerting this beneficial action, possibly by suppressing oxidative stress, and could potentially enhance kidney transplantation outcomes.
