Can an oral supplement keep your blood vessels healthy?

Volunteers 18-40 needed for study entitled “Endoplasmic reticulum stress and vascular ischemia-reperfusion injury in humans.”

The University of North Texas Health Science Center and the Human Vascular Physiology Laboratory are recruiting up to 20 subjects (male and female) to take part in a study that will determine if tauroursodeoxycholic acid (TUDCA) supplementation alters vascular function following forearm ischemia-reperfusion in young healthy humans.

You must be:
• 18-40 years old; males & females
• Generally healthy
• Currently a non-tobacco/nicotine user (cigarettes, e-cigarettes, chewing tobacco, nicotine patch/gum)

Study Requirements:
• Visit Human Vascular Physiology Laboratory at UNTHSC on 3 separate days; the first will be 1-2 hours, the second and third will be 2–3.5 hours
• Participation in this study is voluntary, and if you are a student or employee of UNTHSC your participation (or non-participation) in this study will in no way affect your academic standing or employment.
• Subjects will be compensated for their time and effort.
