The function of the lake sturgeon, Acipenser fulvescens, thyroid system and dietary effects
Bibliographic record
Abstract
The basic properties of the lake sturgeon ('Acipenser fulvescens ') thyroid system were studied to confirm and explain previously reported low plasma thyroid hormone (TH) levels. The THs from a variety of sturgeon tissues were extracted and assayed to determine their concentrations. Once the basic principles of the sturgeon thyroid system were established, the ability of sturgeon to modify thyroid function in response to changes in dietary constituents was studied. Two diets, ocean plankton and Martin's trout pellets, were fed to two groups of sturgeon. Finally the ability of the lake sturgeon to cope with a dietary induced T3-challenge was studied. In conclusion, the lake sturgeon thyroid system has several characteristics that differ from the teleost fish system. It is concluded that the lake sturgeon's thyroid system functions most similarly to organisms that live in low iodide environments like the mammals. (Abstract shortened by UMI.)

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.
