Abstract

fetched live from OpenAlex

Anemia is a cardinal feature of chronic renal failure (CRF) which contributes significantly to the clinical syndrome of chronic uremia. We have conducted a detailed examination of the hematological changes in CRF in the inbred mouse strain C57BL/6J. As in the human situation, CRF mice presented major hematological changes affecting primarily the erythroid cell series. Despite the presence of abundant iron stores in the bone marrow, the CRF mice developed a hypoproliferative anemia of a severity commensurate with the degree of renal impairment. The levels of circulating erythropoietin (EPO) in CRF mice were not significantly different from those in normal control littermates and were therefore inappropriately low for the degree of anemia. In contrast acutely bled control mice with normal renal function showed a significant inverse correlation between the serum EPO level and hemoglobin concentration, indicating an appropriate response to anemia. The chronic administration of recombinant human EPO raised the hemoglobin concentration of CRF mice, a therapeutic effect which was independent of the initial degree of anemia. These observations suggest that this animal model has wide applicability for the study of anemia secondary to CRF.

Not 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.
