Abstract

fetched live from OpenAlex

Zaprionus paravittiger fed with vitamin E supplemented diet (1, 5 and 10 micrograms/ml) showed an increase in median and maximum life spans. Further increase in concentration accelerated the mortality rate. Females exhibited longer life span as compared to males. Malondialdehyde (MDA) content and antioxidant enzymes (catalase and peroxidase) were measured in control and optimum concentration of vitamin E (5 micrograms/ml)-fed flies at various age intervals. MDA content showed an increase with age in control and vitamin E-fed group whereas catalase and proxidase activities showed a decrease with age. The females exhibited lower MDA content and higher activities of catalase and peroxidase as compared to males in control and vitamin E group. Vitamin E feeding caused a significant decrease in MDA and increase in catalase and peroxidase activities. These findings suggest that vitamin E has dose-dependent and sex-specific influence on longevity of Z. paravittiger and support the view that longevity and activity of antioxidant enzymes are positively linked.

Teacher imitation

Not 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.
