Abstract
The concentrations of beta-carotene, retinol and alpha-tocopherol were measured by high-pressure liquid chromatography in ovarian follicular fluid and plasma samples collected at the time of oocyte recovery from patients enrolled in our in vitro fertilization program. The mean beta-carotene levels in follicular fluid [0.182 +/- (SEM) 0.04 nmol/ml] and plasma (0.37 +/- 0.34 mmol/ml) of smokers (n = 5) were significantly (p < 0.025 and p < 0.001, respectively) lower compared with the mean levels in follicular fluid (0.58 +/- 0.10 nmol/ml) and plasma (1.11 +/- 0.09 mmol/ml) in nonsmokers (n = 11). The follicular fluid and plasma retinol and alpha-tocopherol levels were comparable among the nonsmokers and smokers. These findings direct attention to a possible role of the antioxidant beta-carotene, per se, as a biological marker in ovarian oocyte follicular maturation and function.

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
