Correlation between the Airway Branching Patterns and the Heterogeneous Distribution of the Lesions in Bleomycin-Injured Mouse Lung: A 3-D Morphometric Study.
Bibliographic record
Abstract
The possible roles of airway branching patterns on the pathogenesis of lung diseases, especially on the heterogeneous distribution of the lesions, were examined through three-dimensional (3-D) morphometric analysis of a mouse lung injury, induced by bleomycin. On serial sections of a mouse lung damaged by subcutaneous injection of bleomycin, we performed a computer-assisted reconstruction of the lung for visualizing the relation of airways with the distribution of the lesions, and defined the features of bronchial routes to each lesion by four parameters: LTB; the distance from the hilum, Ng; generation numbers, RD(min); irregularity of airway branching, and thetaTB; the grade of airway recurrence. Among these four parameters, only thetaTB was found to correlate with the severity of lesions (p < 0.05 by an ANOVA test), which was proved by a posthoc test (p < 0.0001). These results showing the acini supplied by recurrent branches are more prone to be damaged than those by non-recurrent branches suggest that branching patterns may underlie the heterogeneous distribution of lesions in diffuse interstitial lung diseases.

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.
