Dietary Nitrate to Augment Exercise Training Benefits in DM+PAD
We are seeking approximately 28 people (ages 40-80) with peripheral arterial disease and type II diabetes. This study is based at the Non-Invasive Vascular Laboratory at the Duke Center for Living campus. (REF# Pro00039608)

Effect of Positive Airway Pressure on Reducing Airway Reactivity in Patients with Asthma
Asthma patients who do not smoke and have been using medication for at least a year are needed to take part in a research study at the Duke Clinical Research Unit. (REF# 34572)

Branched-chain Amino Acid Metabolism in Pre-Diabetes: BCAAM-PD
The purpose of this study is to investigate how the Branched-chain Amino Acids contribute to insulin resistance in overweight and obese individuals and their source in the plasma. (REF# 00034434)

Increased Plasma Nitrite, Tissue Oxygenation and Functional Changes in PAD
The purpose of this study is to determine if regular consumption of a high nitrate supplement in conjunction with 12 weeks of supervised exercise training will produce a greater benefit in blood vessel function, muscle function and physical performance than 12 weeks of exercise alone. (REF# 00031918)

Studies of a Targeted Risk Reduction Intervention Through Defined Exercise in Pre-Diabetics: STRRIDE-PD
This study seeks participants between 45 and 75 years of age to evaluate the effects of different amounts and intensities of aerobic exercise. (REF# 12628)

Exercise Dose/Response Effects in Pre-Diabetic Patients
We are looking for men and women who want to participate in an exercise research study at Duke. (REF# 12628)
