Influence of the Pineal Gland on Hypothalamic Content of TRH in the Syrian Hamster
Bibliographic record
Abstract
Blinding adult female hamsters by bilateral orbital enucleation caused an increase in thyrotropin-releasing hormone (TRH) content of the medial basal hypothalamus and also led to an increase in TRH content in the remainder of the hypothalamus (dorsal hypothalamus). Although pinealectomy by itself had no significant effect on the neuroendocrine-thyroid axis, this surgical procedure prevented the inhibition of serum thyroxin observed in blinded hamsters. Pinealectomy also prevented the increase in TRH content of medial basal and dorsal hypothalamus observed in blinded hamsters. The results are consistent with the view that the pineal gland has a CNS site of action and provide evidence that the anti-thyroid influence of the pineal gland can be explained by pineal inhibition of TRH release.

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.
