Causal Role of Brain Networks in Episodic Memory
NCT05374551
Recruiting
The goal of this study is to understand the basic brain mechanisms supporting episodic memory in healthy young adults. Transcranial magnetic stimulation will be used to influence brain activity in regions thought to be important for episodic memory. Behavioral testing and MRI will be used to measure the effects of stimulation on memory and on changes in brain network interactions, allowing us to draw causal inferences regarding the role of specific brain regions in memory processes.

Gut Microbial Metabolites of Apple Polyphenols
NCT06107192
Recruiting
The goal of this controlled feeding trial is to learn about the metabolism of polyphenols, a common class of compounds found in plant-based foods, by the gut microbiome. It will evaluate how differences in gut bacteria across individuals influence metabolism of polyphenols from foods, which may influence health benefits that people receive from different foods.

The Impact of Light Exposure on Cognitive Function in Classrooms
NCT06325150
Recruiting
Humans are constantly exposed to a variety of light types, created naturally or through artificial means. Light exposure captured by the eyes impacts many physiological functions in humans, including but not limited to cognitive output, fatigue levels, and mood regulation. The level of impact on cognitive learning from different types of light on undergraduate adult students remains unclear.

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 and... Read More

Sex Disparities in Hypoxic Sympatholysis and Impact of Obesity
NCT04436731
Recruiting
Patients with sleep apnea are at increased risk of developing cardiovascular disease - with women at potentially greater risk than men. Contributing mechanisms are not well understood, but may be related to how women respond to low oxygen and, given over 70% of patients with sleep apnea are obese, the impact of obesity. This project seeks to increase our understanding of mechanisms that may contribute to sex differences in the cardiovascular response to low oxygen with the hope that this knowled... Read More
