Abstract

fetched live from OpenAlex

An aldosterone-secreting adrenocortical adenoma was removed by surgery from a 15-year-old boy who exhibited signs characteristic of Conn’s syndrome including hypertension, potassium depletion and increased aldosterone production rate. The neoplasm was found to consist mainly of clear cells by light microscopy. Ultrastructural investigations revealed that the neoplasm was composed chiefly of fasciculata cells characterized by mitochondria with vesicular cristae. Some mitochondria, however, possessed tubular cristae reminiscent of those occurring in zona glomerulosa cells. It appears that mitochondria are not rigidly static constituents of cells but they can change constantly in order to satisfy variations in functional need. Other ultrastructural features included accumulation of lysosomes and lipofuscin granules, an increase of the rough-surfaced endoplasmic reticulum membranes, lipid depletion, focal hypertrophy and dilatation of the Golgi sacculi, and a pronounced hypertrophy of the smooth-surfaced endoplasmic reticulum. The latter alterations were thought to represent the fine structural manifestations of enhanced cellular activity associated with increased production of aldosterone.

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.
