Oral Trehalose Therapy to Reverse Arterial Aging in Middle-Aged and Older Adults
December 9, 2015 updated by: University of Colorado, Boulder
The proposed study will assess the ability of a naturally occurring sugar to improve the function of arteries with age.
Overall, the proposed research project has the long-term potential to influence clinical practice guidelines by establishing a novel, easy to deliver, cost-effective therapy for treating age-associated arterial dysfunction and reducing the risk of cardiovascular disease with age.
