Abstract

fetched live from OpenAlex

OBJECTIVE: To compare histopathologic features of a fibroproliferative disorder in horses (exuberant granulation tissue-EGT) and people (keloid). SAMPLE POPULATION: Archival tissue samples of EGT (n = 8) and keloid (12). METHODS: After automated hematoxylin and eosin, histochemical (Gomori trichrome, Verhoeff-van Gieson elastin) and immunohistochemical (vimentin, α-smooth muscle actin, CD34, CD68, CD117) stainings, tissue sections were evaluated using a semi-quantitative grading scale for presence or absence of ulceration, keloidal collagen, myofibroblasts, and elastic fibers as well as degree of inflammation, fibrosis, vascularity, and orientation of collagen fibers. RESULTS: Superficial dermis and deep dermis of both horses and people had increased numbers of haphazardly oriented thickened collagen fibers; however, only keloids contained "keloidal" collagen. Fibroblast numbers were markedly increased in both groups but only EGT had myofibroblasts. Minimal vascularity was observed in the deep dermis of both groups. The superficial dermis in EGT was characterized by small vessels within immature granulation tissue. Macrophages and mast cells were infrequently found in both groups but polymorphonuclear cells were markedly increased in EGT. CONCLUSIONS: Humans and horses are the only mammals known to naturally develop excessive granulation during wound healing; however, similarities and differences between fibroblast populations and associated collagen have not been reported. Inflammatory response may contribute to observed differences in the cellular populations, with EGT possessing markedly increased myofibroblasts, small vessels, and acute inflammatory cells compared with keloids. Further work is warranted to develop common treatment strategies for these fibroproliferative conditions.

Teacher imitation

Not 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.
