Subject: 78'th update on fly longevity experiments

    This is the 78'th update of my fly longevity experiments. Average
temperature was 24.8 C during this run. Here I take yet another look at
combinations of acetyl-L-cysteine (ALC), and some antioxidants.
    CDP choline and citrulline both turned out to be a duds this time, and
ginkgo was toxic. As before, nicotinamide at a high dose was again toxic,
possibly because of inhibition of SIR2. Lipoic acid at the 100 mg dose
appeared to be ineffective this time, but the 200 mg dose was slightly
beneficial. Surprisingly the 400 mg dose was either toxic this time, or
very unlucky. Overall there is not much of interest here.
    Next run, I look away from ALC, investigate some novel supplements,
and obtain some intriguing results.
