Pulsatile Discharges of Luteinizing Hormone in the Ovariectomized Rat during the 24-Hour Day
Bibliographic record
Abstract
Blood samples were taken every 5 min for a 2-h period commencing at 09.00 h or epsilon 13.00 h from long-term ovariectomized (OVX) rats under regular lighting conditions (lights on 05.00-19.00 h), and commencing at 09.30 h or 14.00 h from long-term OVX rats under reversed lighting conditions (lights on 18.00-08.00 h), the latter equivalent to starting sampling at 20.30 h or 01.00 h under regular lighting. Five rats were used in each group, and luteinizing hormone (LH) was measured in duplicate aliquots of each sample by radioimmunoassay. Pulsatile increases in plasma LH concentrations were observed in all 20 animals, and mean, peak, and nadir plasma LH concentrations for each group did not differ between sampling periods. Similarly, the time of day did not affect the frequency at which pulsatile discharges of LH occurred. These data suggest that pulsatile discharges of LH in long-term OVX rats occur throughout the 24-h day.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
