Down-Regulation of Aquaporin 1 in Rats With Experimental Acute Necrotizing Pancreatitis
Bibliographic record
Abstract
OBJECTIVES: The objectives of this study were to investigate the expression of aquaporin 1 in capillary endothelial cells of rats with experimental acute necrotizing pancreatitis (ANP) and to explore its pathogenic role in capillary leak. METHODS: Sixty-four male Sprague-Dawley rats were randomly divided into control (n = 32) and ANP groups (n = 32). Eight rats in each group were killed at 3, 6, 12, and 18 hours after induction of experimental models. Quantity of ascites and levels of serum amylases were measured. Capillary permeability in pancreas, lung, and intestinal tissue was detected by Evans blue extravasation method. Aquaporin 1 expression in pancreas, lung, and intestinal tissue was detected by real-time polymerase chain reaction, immunohistochemical staining, and Western blot. RESULTS: Serum amylase level was significantly higher in ANP group than in controls (P < 0.05). Evans blue concentration in tissues in the ANP group was significantly higher than that in controls (P < 0.05). Aquaporin 1 mRNA and protein expressions in tissues were significantly less in the ANP group than in the controls (P < 0.05). CONCLUSIONS: The expression of aquaporin 1 was down-regulated in the pancreas, lung, and intestinal tissue of ANP rats, which could play an important role in the pathogenesis of capillary leak syndrome.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedLabeled directly by 3 models reading the full record.
