This study will use dual energy x-ray computed tomography (DECT) to evaluate the relationship between heterogeneous perfusion, hypoxia (low oxygen in inspired gas) and induction of pulmonary vascular dilatation to characterize emphysema susceptibility in a normal smoking population. The investigators will correlate DECT measures of perfusion with lung injury measured by single photon emission computed tomography (SPECT). The investigators will study the effect of pulmonary arterial vasodilation to see if it eliminates indices of persistent lung injury in smokers that are susceptible to emphysema

Vascular Dysfunction in Human Obesity Hypertension: Integrative Role of Sympathetic and Renin-Angiotensin Systems (VANISH study)

Heart and Vascular Vascular Disease Healthy Subjects Adult Subjects Female Subjects Male Subjects

The purpose of the study is to test the effects of blocking sympathetic nerve activity with a drug called clonidine on blood vessel function and muscle nerve activity in adults who are obese and have high blood pressure.

The cohort of subjects will consist of 69 healthy young men and women age 18-79 years who are obese, defined as a body mass index \> or = to 30 kg/m2, who have untreated systolic hypertension (systolic blood pressure \> or = to 130 - \<180 mmHg- average of at least 3 measurements 2 min apart after 10 min seated resting position). These 69 subjects will then be randomized to 3 treatment arms: clonidine (0.1 mg/day), hydrochlorothiazide (25 mg/day) or placebo for 4 weeks in years 1 and 2. All tablets will be encapsulated by to look identical. Subjects will randomly (1:1:1) receive one of the following combinations in a double-blind, placebo-controlled design:

1. Oral clonidine (0.1 mg twice/day)
2. Oral hydrochlorothiazide (12.5 mg twice/day)
3. Oral placebo

Effects of Inorganic Nitrate Supplementation on Cerebrovascular Aging and Arterial Stiffness (INCA) Study

Heart and Vascular Vascular Disease Healthy Subjects Adult Subjects Female Subjects Male Subjects

This study investigates the effect of dietary inorganic nitrate supplementation on 1) large elastic artery stiffness and hemodynamics and 2) cerebrovascular function in middle-aged and older adults. Participants will be randomized to consume either nitrate-containing or nitrate-depleted beetroot juice.

Evaluation of Transcatheter Aortic Valve Replacement Compared to Surveillance for Patients with Asymptomatic Severe Aortic Stenosis

This study will evaluate the safety and effectiveness of the Edwards SAPIEN 3/SAPIEN 3 Ultra Transcatheter Heart Valve (THV) compared with clinical surveillance (CS) in asymptomatic patients with severe, calcific aortic stenosis.

Curcumin and vascular function in CKD

Internal Medicine Nephrology Heart and Vascular Kidney Disease Vascular Disease Heart Disease Adult Subjects Female Subjects Male Subjects

The proposed research is clinical study evaluating the therapeutic benefits of curcumin on vascular function in patients with chronic kidney disease (CKD). The study aims to establish that curcumin will improve endothelial function and reduce large artery stiffness by reducing oxidative stress and in conjunction with lowering markers of inflammation and oxidative stress. In addition, the study will evaluate the potential benefit of curcumin on cognitive function in patients with CKD.

A Randomized Controlled Trial Evaluating the Effect of the Oxytocin Infusion Rate on Fetal Heart Rate Changes and Maternal Fetal Outcomes during the Initiation of Combined Spinal-Epidural Labor Analgesia

Anesthesia Heart and Vascular Electrophysiology Healthy Subjects Adult Subjects Female Subjects

The reported risk of nonreassuring fetal heart trace following neuraxial analgesia is 3-23%. This variability may be due to fluid and oxytocin management prior to and during the initiation of neuraxial analgesia. The study hypothesis is that decreasing the oxytocin infusion rate by 50 % prior to initiation of combined spinal epidural analgesia will cause a reduction in the incidence of adverse fetal heart rate changes.
