Effect of proanthocyanidins-rich fraction-supplemented diet on the activity and level of acetylcholinesterase (a), Caspase-3 (b), and Caspase-9 (c) in D. melanogaster. The results were expressed as mean ± SD of the activity and quantity of the enzymes. Differences in the results were considered statistically significant (p < 0.05) at 95% confidence level. All experiments were conducted in three replications (n = 3)
