Abstract
High-mobility-group box chromosomal protein 1 (HMGB1) has recently been identified as a late mediator of various kinds of acute and chronic inflammation. A method for efficiently removing HMGB1 from systemic circulation could be a promising therapy for HMGB1-mediated inflammatory diseases. It is well known that the cationic portion of HMGB1 binds to heparin, which has abundant sulfates in its structure. In this study, we determined whether spherical sulfated cellulose (SC) efficiently adsorbed HMGB1, as well as other inflammatory mediators, in vitro. Then, we investigated the efficacy of hemoperfusion with the SC (SC group) or cellulose beads (control group) at adsorbing endogenous mediators, including HMGB1, in vivo. We have demonstrated that the SC adsorbed significantly larger amounts of HMGB1, interleukin (IL)-4, and IL-8 when compared with cellulose beads, in vitro. Hemoperfusion with the SC for 30 minute, starting 2 hour after an abdominal opening and closure operation, significantly reduced serum HMGB1 levels (p = 0.004) and consistently increased serum IL-10 levels, in vivo. These data suggest the potential benefits of hemoperfusion using the SC in treating HMGB1-mediated inflammatory diseases.

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
