Abstract
This study assessed the effects of a two-layer method (TLM), using perfluorocarbon and UW solution, on the quality of human pancreata following storage and islet yield/function after isolation. In part A, TLM was applied immediately after procurement and the energetic profile was compared to a group treated with UW solution only (control) throughout 24-h storage. In part B, cadaveric human pancreata were procured and subjected to a TLM after cold storage in UW solution (TLM group) or UW solution (control group). Energetics, lipid peroxidation, and islet recovery/function were assessed after preservation at 4 degrees C. In part A, after 9-h storage, the energetic profile (ATP, ATP/ADP, energy charge) for the TLM group was superior to controls. In part B, TLM treatment resulted in consistently greater ATP, ATP/ADP, and energy charge values than with storage in UW solution alone (p < 0.05). UW treatment resulted in 40% greater peroxidative damage than in the TLM group (p < 0.05). Islet recovery and functional viability were 30-40% higher following TLM treatment (p < 0.05). These data support the hypothesis that islet viability and yields can be significantly improved using a brief period of TLM treatment following conventional UW storage; reduced energetic and oxidative stress are implicated as potential mechanisms.

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 it
