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.

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
