Rooibos tea flavonoids increase mineral content in human osteoblast-like cells
Bibliographic record
Abstract
Some cross-sectional and prospective studies have demonstrated a positive correlation \nbetween habitual tea consumption and bone mineral density in post-menopausal women. \nRooibos tea contains no caffeine and is a rich source of flavonoids such as rutin, orientin, \nhyperoside and luteolin. These flavonoids have similar structures to estradiol, and \ntherefore may act as estrogen mimics to promote favourable outcomes in bone. The \noverall objective of this research was to identify flavonoids that could enhance mineral \ncontent in human osteoblast Saos2 cells. Mineral was quantified by alizarin red staining \nand characterized by quantifying alkaline phosphatase (ALP) activity, cell mitochondria \nactivity and toxicity, in addition to changes in regulatory markers of osteoblastic activity. \nRutin (≥50μM), hyperoside (≥5.0μM), orientin (0.1μM-1.0μM, 15μM-100μM) and \nluteolin (5.0μM) enhanced mineral content. This was in part due to elevated ALP and \nmitochondrial activity, and lower toxicity, pro-inflammatory cytokines, and Wnt \ninhibitors.

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.
