We performed an observational study where we compared diurnal changes of the gut microbiota with temporal changes of plasma metabolites.

Basal, epinephrine-stimulated, and epinephrine-induced lipolysis of fat cells from control rats showed diurnal changes, and the rhythms and their amplitude were affected by meal feeding.

Both s-TK and s-CA 125 levels showed considerable diurnal changes over the 24-h period in individual patients, in marked contrast to normal subjects.

Diurnal changes of glycogen contents in heart and adipose tissue differed from those in liver and skeletal muscle.
