Outcome Measures
Primary Outcomes (1)
PON1 activity
PON1 activity is assayed in HDL isolated from plasma of subjects from the placebo and retinoic acid groups by using UV spectrophotometry in a 96-well plate format using phenyl acetate or paraoxon as substrates.
changes from baseline in PON1 activity at 12 weeks
Secondary Outcomes (1)
Lp-PLA2 activity
changes from baseline in Lp-PLA2 activity at 12 weeks
Other Outcomes (1)
cholesterol efflux capacity
changes from baseline in cholesterol efflux capacity at 12 weeks
Study Arms (2)
control
PLACEBO COMPARATORthe participants in this arm are instruted to consume placebo capsules
treatment
EXPERIMENTALthe participants in this arm are instruted to consume retinoic acid capsules
Interventions
During the trial period, the participants are instructed to consume retinoic acid capsules twice daily (30 min after breakfast and supper).The retinoic acid capsules provided a total daily intake of 10 mg of retinoic acid.
During the trial period, the participants are instructed to consume placebo capsules twice daily (30 min after breakfast and supper).The placebo capsules are composed of starch and pigment.
