Testicular Protein Synthesis during the Response to Subtoxic Levels of Cadmium
Bibliographic record
Abstract
Male rats received one injection of a 'subtoxic' amount of Cd2+ (9.2 mumol/kg body weight) as cadmium chloride and the testes were removed 24 h later. Homogenate fractions of tests that had been freed of ribosomes were tested for their activity in cell-free protein-synthesizing systems using excess exogenous rat liver ribosomes and mRNA. A marked decrease in the incorporation of free [14C]-phenylalanine into peptide was observed with the testes preparations from the cadmium-treated rats. The results indicated that about half of the effect of cadmium was due to decreased aminoacyl-tRNA synthetase activity and the other half was due to decreased binding of [14C]-phenylalanyl-tRNA to ribosomes. The results are discussed relative to the contrasting results obtained in kidney and liver preparations.

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.
