Inclusion criteria

Inclusion criteria: Healthy adult males aged 20-35 years

Exclusion criteria

Exclusion criteria: 1. Previous history of cardiovascular disease (ischemic heart disease - angina or recent or old myocardial infarction, cerebral vascular accident, or peripheral vascular disease) 2. Homeostatic disorders 3. Any several chronic diseases 4. Hypertension or dyslipidemia 5. Smoking subjects 6. Alcoholism 7. Other toxic abuse

Design outcomes

Primary

MeasureTime frame
Furanocoumarin metabolites will be identified through liquid chromatography coupled to Orbitrap mass spectrometry. Concentrations of furanocoumarins will be determined by liquid chromatography coupled to tandem mass spectrometry (LC?MS/MS). These determinations will be carried out in first morning urine samples collected the day before the first intervention and in the morning following each intervention.
