Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Attenuation by the succinate prodrug of toxin-induced decrease in mitochondrial respiration.
Time Frame: by end of 2018
|
Data will be assessed using 2-tailed Student's t-test.
Dose-response curves for respiration will be made for each toxin and IC50 calculated.
In case of difficulties in demonstrating acute toxicity of chemical agents, dose-titration experiments and long-term incubation (up to 24 hours) will be performed
