Measurement of Pulmonary Inflammation Using F-NOS Positron Emission Tomography (PET/CT) in E-cigarette Users

This is a 1 – 2 month study examining the extent of lung inflammation between e-cigarette smokers, cigarette smokers, and non-smokers using a new radio tracer, FNOS. FNOS is an experimental radio tracer used to look for inflammation in different parts of the body. The tracer that we will be …

Development and Maintenance of Software for MR Spectroscopic Imaging

This research study will test the performance of new magnetic resonance imaging techniques at 7.0 Tesla. These new methods have already been tested in model systems and need to be tried on human subjects prior to their applications in determining important substances in the whole brain. . This study is …

Investigation of the Effect of Branched Chain Amino Acids on Fat-Induced Insulin Resistance in Healthy Adults.

Elevations in plasma levels of branched chain amino acids (BCAAs, comprising leucine, valine, and isoleucine), a large component of protein, are strongly associated with insulin resistance and type 2 diabetes, but mechanisms for this relationship are unclear. This protocol will determine whether excess BCAAs worsen free fatty acid-induced insulin resistance. …
