WBC reduction reduces storage‐associated RBC adhesion to human vascular endothelial cells under conditions of continuous flow in vitro
Bibliographic record
Abstract
BACKGROUND: The effects of storage duration, WBC reduction, and irradiation on RBC adherence to vascular endothelia are unknown and are investigated under conditions of continuous flow. STUDY DESIGN AND METHODS: Thirty-two RBC units were collected and divided into three groups, non-WBC-reduced (NWR), WBC-reduced (WR), and irradiated-WBC-reduced. Aliquots of RBCs were removed on Days 1, 15, and 28 of storage for analysis. The RBC suspensions were then perfused at a 1.5 percent Hct in a protein-poor medium under conditions of continuous flow over human umbilical vein endothelial cell monolayers. On each slide, 25 randomly chosen sites were videorecorded over 10 minutes, and the number of RBCs adherent to the endothelial cell monolayer was counted. RESULTS: NWR RBCs stored for 28 days demonstrated a greater degree of adherence to endothelial cells compared to Days 1 and 15 (p < 0.03). The WR group had significantly fewer adherent RBCs than the NWR group on day 28 (p < 0.01). Irradiation had no effect on RBC adherence. CONCLUSION: Prolonged storage of NWR RBCs increases RBC adherence to endothelial cells in vitro. WBC reduction before storage abrogates the effect of storage duration on increased adhesion. Studies to assess whether an in vivo effect occurs are required.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
