Clinical trials: Peripheral Vascular Response
Major Depressive Disorder
Linking Affective Dynamics in Response to Daily Stress to Peripheral Vascular Function in Working Age Adults
The objective of this proposal is to determine whether heightened negative affective responsivity (NA-R) to daily stressors is related to blunted nitric oxide (NO)-mediated endothelium-dependent dilation (EDD) in working age…

Heart Disease, Heart Failure
Investigating Systemic and Local Vascular Responses to Apelin in the Context of Renin-angiotensin Upregulation
The apelin-APJ system is a relatively new discovery. It has generated interest in part due to it's apparent ability to counteract the renin-angiotensin system, which is frequently overactive in many cardiovascular disease.
