Patterns of Internal Elastic Lamina Morphology in the Canine Common Carotid Artery
Bibliographic record
Abstract
The internal elastic lamina (IEL) of normal canine carotid arteries was examined by scanning electron microscopy in pressure-fixed specimens with intact endothelium. IEL appearance showed a marked variation between animals and was classified into fenestrated sheet, fibrous, and mixed varieties. This interpretation of the apparent morphology was confirmed with transmission electron microscopy. It was clear that IEL fenestrae were associated with surface depressions and that in areas of fibrous IEL there was surface elevation over individual fibres. Within individual animals there was little variation in the pattern of IEL either along or between common carotid arteries. If theories of atherogenesis involving the IEL are correct, the variation of IEL patterns between animals would suggest a corresponding variation of incidence and severity of atheromatous lesions of the common carotid artery between animals. Further, the occurrence of fibrous areas distributed throughout the fenestrated sheet would suggest a focal distribution of lesions along such arteries.

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.
