Abstract
Acute systemic injection of ginseng saponin (GS) significantly elevated both the total and maximum heat production in young rats (3-6 months) and improved their cold tolerance under severe cold (-10 degrees C under helium-oxygen). However, pretreating the animal with the optimal dose (10 mg/kg) of GS devoid of Rg1 and Rb1 failed to elicit any beneficial effect in improving the cold tolerance. Pretreating the animal with Rb1, but not Rg1, increased thermogenesis as well as cold tolerance in young rats. A similar beneficial effect in improving cold tolerance was also observed when old rats (26-28 months) were pretreated with the same doses of Rb1 (2.5 and 5.0 mg/kg). Our results indicate that Rb1 is the key ingredient in GS-mediated enhancement in thermogenic capacity and that both young and old rats can benefit from this treatment for enhanced cold tolerance.

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 it
