Abstract
Fetal/neonatal exposure to the endocrine disruptor bisphenol A (BPA) has induced obesity and increased glucose intolerance. We hypothesized that chronic BPA exposure would worsen the obesity and glucose intolerance induced by a high fat diet (HFD). The drinking water of C57bl/6n dams was treated with vehicle (VEH) or BPA (25 ng/ml) from gestation day 11.5 to postnatal day 21. Another group was treated with oral diethylstilbestrol (DES, 1 μg/kg/day) during gestation. Progeny were treated with VEH (VEH and DES groups) or BPA (2.5 ng/ml) in the drinking water and fed either a control diet (CD) or HFD from weaning until euthanasia at 4 months of age. CD-fed mice were similar in size; however HFD-BPA males and HFD-DES mice were smaller than HFD-VEH mice. No CD-fed mice were glucose intolerant. All HFD-fed mice were glucose intolerant. Cholesterol and triglyceride were increased in HFD-VEH mice and HFD-BPA males. Total fat weight and adipocyte area were similar in HFD-VEH and HFD-BPA mice and reduced in HFD-DES mice. HFD-BPA females increased perirenal and reduced gonadal fat weights. Reduced leptin and increased IL-6 in CD-BPA and CD-DES mice were not found in their HFD-cohorts. Adiponectin levels were similar. Thus, although chronic BPA exposure did not increase body size or increase glucose intolerance, it induced an adipokine imbalance in CD-fed mice and sex-specifically altered the lipid response and adipose deposition when fed the HFD.

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
