Abstract

fetched live from OpenAlex

In order to provide an ultrastructural description of kaliopenic nephropathy in rats, potassium deficiency uncomplicated by chloride depletion or extracellular fluid volume expansion was induced by dietary means alone. After 12 days, serum and muscle analyses demonstrated severe potassium depletion, while urine concentrating ability was markedly impaired. Although micropuncture techniques demonstrated that net fluid transport in proximal tubules was normal, the epithelial cells showed the following morphological alterations: electron-lucent vacuoles and lysosome-like dense bodies were numerous, focal cytoplasmic degradation was present, and intercellular spaces were dilated in many proximal tubules. Medullary cell droplets were characterized by fusion, massive enlargement with sequestration of cytoplasmic components such as ribosomes, and occasional extrusion through ruptured plasma membranes--features not previously reported.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
