abstract：:Acetate is the primary product of ethanol catabolism and can accumulate in the blood at concentrations of up to 2 mM following ethanol consumption. It has been suggested that some of the pharmacological actions of ethanol are mediated via acetate, which can lead indirectly to the release of endogenous adenosine. In th...

abstract：:Postural control strategies are frequently assessed through posturography on a firm surface. Their motor efficiency is related to the coordination between center-of-gravity (CG) and center-of-pressure (CP) movements, which results from long-term training. However, when standing on a seesaw favoring pitching body motio...
