Research studies are essential for the advancement of scientific discovery. At the NC Research Campus, scientists are continually recruiting participants for studies and focus groups. Review the studies that are currently recruiting below to find out if there is a study for you. To keep up with new studies as they become available, sign up for our e-mail alert.

Dietary Supplement and Sperm Function
Steven H. Zeisel, MD, PhD, is the Kenan Distinguished Professor of Nutrition and Pediatrics at the University of North Carolina Chapel Hill Nutrition Research Institute (NRI) on the North Carolina Research Campus in Kannapolis. The Zeisel Lab at the NRI is recruiting men between the ages of 18 and 60 to participate in a new research study to determine if taking a dietary supplement will impact male infertility. You will be paid for your time. To volunteer for this research study, please contact 704-250-5035 or Sperm_Study@unc.edu.
The title of the research study is CHDH and sperm function: Effects of betaine. The purpose of the research is to determine whether a common genetic variation in men causes abnormal sperm function and whether treatment with a dietary supplement (betaine) can correct this problem. Men between the ages of 18 – 60 years old are eligible to participate in this research.
All research procedures will be conducted at the UNC Nutrition Research Institute (NRI) at the North Carolina Research Campus (500 Laureate Way, Kannapolis, NC 28081). Prior to enrolling in the research study, you will be asked to come to the NRI in Kannapolis, NC for approximately 2 hours. We will ask you some questions about fertility, and you will be asked to provide a blood sample and sperm sample to ensure that you may safely participate. You will also be asked to complete a food questionnaire. If you are eligible, the research study will last for approximately eleven weeks and consists of blood and sperm studies on day 0, day 10, day 30, day 50 and again on day 75. Study subjects will be asked to take capsules containing a dietary supplement. Participants will receive $600 upon completion of the research study.
Nutrition researchers want to find out why some people get more easily sore after exercise than others. We already know how small genetic variations can make a big difference. It may mean that some people need more of some important nutrients and that not getting that extra amount makes muscles just a little more vulnerable. Martin Kohlmeier, MD, is now recruiting healthy caucasian men (ages 18-80) who:
Dr. Kohlmeier is investigating how small genetic differences change the metabolism of choline and what that means for muscle stability. For that, he needs help. We are first screening potential participants with an arm strength measurement, 12 biceps curls (takes less than 2 minutes), a blood draw before the exercise and again three days later. We also carry out a DEXA scan (like a bone density test) and ask that you report everything you eat and drink for three days.
Completion of all screening procedures will be compensated with $50. Those with the needed test profile will be invited for a 6-week research study of a choline supplement (a vitamin-like nutrient), with a total of 3 more rounds of 12 biceps curls, 6 blood draws, and additional 9 days of food records. We will provide an additional incentive of $150 for completion of this supplement research study.
If you want to help with this research study for muscle nutrition, you should contact Dr. Kohlmeier at firstname.lastname@example.org and arrange for an appointment.
The number of people with risk factors for diabetes continues to increase. Abnormal insulin sensitivity is a condition where the body is not normally responding to elevations in blood sugar. It develops many years before diabetes, and may increase your risk of developing diabetes in the future. The purpose of this research study is to determine if the nutrient betaine, found in beets, spinach and wheat products, can enhance the production of FGF21, a molecule that is believed to promote insulin sensitivity. We are recruiting males and females ages 21-70. Individuals that have a known cystathione beta synthase deficiency, who do not tolerate betaine, or who are pregnant, plan to become pregnant, or are breastfeeding should not participate in this study. Participants will volunteer for two 3-day periods separated by 4 weeks. Participants will be asked to eat defined meals and drink a betaine supplement and a placebo in a random order. We will collect blood samples after the betaine supplement has been consumed. Participants will receive $400 for research study completion.

Spectrum Discovery Center is recruiting for a coffee study that will take place the week of April 7. Males and females ages 18 to 64 are needed. If you or someone you know is interested, please call 704.250.1200 and ask for the Coffee Screener. Also, remember to register in the Sensory Spectrum database at www.spectrumdiscoverycenter.com. It is free and easy.
