Imaging Techniques in MRI
NCT01130545
Recruiting
Background: - Magnetic resonance imaging (MRI) scans must be performed according to specified sets of parameters that provide optimal images of each organ and each area of the body. These scanning parameters are often specific to the institution or organization at which they are employed, and may also depend on the manufacturer of the MRI scanning equipment. Because MRI scanning equipment is always being updated and upgraded, researchers are interested in developing new and optimized scanning p... Read More

New Heart Imaging Techniques to Evaluate Possible Heart Disease
NCT01399385
Recruiting
Background: - Imaging tests, such as magnetic resonance imaging (MRI), can provide information about heart and blood vessels. The tests let doctors can see the amount of blood vessel narrowing and vessel wall thickness. This information may help diagnose and treat heart disease and other conditions that lead to heart attacks. Better MRI methods are needed to improve heart disease diagnosis, especially by avoiding the use of radiation. Researchers are testing new techniques to improve the qualit... Read More

Neuromodulation of Brain and Emotional Responses to Psychological Stress
NCT06603064
Recruiting
Investigators are conducting this study to test if temporarily and non-invasively stimulating the brain will affect the emotional response to stress in healthy participants. Participants will perform a series of tasks while completing an MRI scan. After this, participants will be randomized to undergo transcranial magnetic stimulation (TMS) at two visits, undergoing active stimulation at one visit and undergoing 'sham' stimulation at another visit. Immediately following both stimulation session... Read More

Gut Oxalate Absorption in Calcium Oxalate Stone Disease
NCT06331546
Recruiting
The goal of this clinical trial study is to test if patients with idiopathic calcium oxalate kidney stones have an increased absorption of dietary oxalate, which would lead to increased urinary excretion of oxalate. The study will recruit adult patients with a history of calcium oxalate kidney stones and healthy volunteers without kidney stones. Participants will * ingest fixed diets containing low and moderately high amounts of oxalate for 5 days at a time * ingest a soluble form of oxalate... Read More

The Gut and Skin Microbiome in Vitiligo Disease Progression
NCT03577327
Recruiting
Investigators plan to perform a pilot study that aims to characterize the microbiome of human vitiligo patients with both active and stable disease and compare this to the microbiome of age and sex matched controls. The investigators aim to answer the question whether the gut and skin microbiome of patients with vitiligo differs from the general population.

A Study of the Blood Levels of Palovarotene in Participants With Abnormal Liver Function Compared to Healthy Adult Participants After Intake of a Single Dose
NCT06908954
Recruiting
The main aim of this study is to understand how moderate and severe liver impairment (based on the Child-Pugh classification) affects the body's processing of a single dose of 10 mg maximum of palovarotene, compared to healthy participants with normal liver function. The study will also assess the safety and tolerability of the single dose of palovarotene. Participants will be enrolled in stages and divided into three groups based on their liver function: * Group 1: Healthy participants with... Read More
