Les actions du chlorfenprop-methyl sur l'integrite membranaire dans les mitochondries des plantes
1983
Summary The action of chlorfenprop-methyl, chlorfenprop and its cysteine conjugate was studied on potato tuber mitochondria. Chlorfenprop-methyl altered membrane structure at 250 μM. leading to a loss of membrane integrity. Chlorfenprop and its cysteine conjugate were without any significant effects. From what is known about the rapid hydrolysis of chlorfenprop-methyl in plant tissues and from the results presented in this paper, it was deduced that alteration in intra-cellular membrane integrity is not a mechanism of phytotoxic action for chlorfenprop-methyl.

Randomized Trial : D-Glyceric Acid Activates Mitochondrial Metabolism in 50–60-Year-Old Healthy Humans
2021
Background: Based on earlier studies, natural metabolite D-glyceric acid (DGA) does not seem to play any role in whole-body metabolism. Nevertheless, one ethanol oxidation-related rat study with controversial results raised our interest. According to preparatory studies for the regulatory approval of DGA, some highly conserved mechanism seems to subtly activate the cellular energy metabolism. Therefore, the present 25-days double-blind human study with placebo control was initiated. Purpose: The main target in the present study with 27 healthy 50–60-year-old human volunteers was to find out whether an “acute” 4-days and a longer 21-days exogenous DGA regimen caused moderate activation of th…
