Abstract
This study examined whether radiation sensitivity measured by lymphocyte apoptosis could be ameliorated by a complex anti-oxidant/anti-ageing dietary supplement. We also examined lymphocytes from both genders of normal (Nr) mice as well as transgenic growth hormone (Tg) mice that express strongly elevated reactive oxygen species processes and a progeroid syndrome of accelerated ageing. We introduce Tg mice as a potentially valuable new model to study radiation sensitivity. Isolated lymphocytes from all experimental groups were exposed to gamma radiation and the time course of apoptosis was measured in vitro. Kinetics of radiation-induced apoptosis was similar among groups, which peaked at 8 h, but maximal levels differed significantly between groups. Nr male mice had 60% lower levels of radiation-induced apoptosis than Tg males, supporting our hypothesis that Tg mice would be radiation sensitive. The dietary supplement protected lymphocytes in male mice of both strains, with proportionally greater reductions in Tg mice. Lymphocytes from female mice (both Nr and Tg) were highly radiation resistant compared to males and the supplement provided no additional benefit at the doses used in this study. These results highlight that radiation-induced apoptosis is complex and is modified by genotype, dietary supplements and gender.

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
