Effect of Low Dietary Vitamin D Fed Prior to and During Pregnancy and Lactation on Maternal Bone Mineral Density, Structure, and Strength in C57BL/6 Mice
Bibliographic record
Abstract
Several studies have shown that diets containing lower vitamin D than in the AIN-93G diet do not compromise bone structure, bone mineral density (BMD), and/or bone strength in male and female mice. This study determined if a diet containing low vitamin D from prepregnancy through to the end of lactation maintained these bone outcomes to a similar extent as a high vitamin D diet. Mice were fed an AIN-93G diet with 25 (LD diet) or 5000 (HD diet) IU vitamin D/kg diet from premating through to lactation (n = 15/group). Of the major structure outcomes, only cortical area fraction of the distal femur was lower (P <0.05) with the LD diet. Lumbar vertebra BMD was lower (P <0.05) with LD whereas distal femur BMD and bone strength at 3 sites did not differ. Dams fed an LD diet premating through to the end of lactation had largely similar bone outcomes to dams fed a HD diet.

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.
