This small pilot study aims to test a new tool for analyzing gut bacteria and see if personalized prebiotic supplements can improve gut health in healthy adults who drink alcohol moderately. Twenty participants will take a daily prebiotic for 60 days and provide stool samples. Re…

This study aims to understand if gently stimulating a nerve in the outer ear can also activate a deeper nerve that controls stomach function. Researchers are testing this in 30 healthy volunteers by placing electrodes on the ear and neck to measure nerve signals. The goal is to g…

This study aims to understand how the body processes fat and sugar at rest, and how this relates to insulin resistance—a key factor in developing type 2 diabetes. Researchers are comparing overweight, sedentary adults with lean, aerobically trained adults, measuring them before a…

This study aims to understand why some people's blood pressure is more affected by salt in their diet than others, especially looking at differences between African American and Caucasian individuals. Healthy volunteers will follow a low-salt diet for one week and a high-salt die…

This study is testing a special education program designed to help first-time mothers with breastfeeding. The program combines information about breastfeeding with motivation techniques and relaxation methods from 'hypnobreastfeeding.' Researchers want to see if this approach imp…

This study aims to understand how a high dose of inhaled nitric oxide gas affects blood chemistry in healthy people. Ten volunteers will breathe the gas for short periods over five days while being closely monitored. The goal is to gather safety data on how the body forms and cle…

This early-stage study aims to understand how a common antibiotic (rifampicin) changes the way the body processes an experimental drug called HSK31858. It involves 24 healthy volunteers who will take both drugs in a set sequence. The main goal is to measure drug levels in the blo…

This study aims to understand why people with COPD struggle with exercise. Researchers will compare the total and lung-specific blood volume of 32 people with COPD to an equal number of healthy, matched volunteers. The goal is to see if lower blood volume is a key reason for redu…

This study aims to understand how stimulating specific areas of the brain with magnets affects automatic body functions, particularly in the gut and heart. Researchers are testing this in healthy adults and people with irritable bowel syndrome (IBS) or functional dyspepsia. The g…

This early-stage study aims to measure how much of an oral dose of the experimental drug cenerimod actually gets into a person's bloodstream. Six healthy male volunteers will take a cenerimod pill and later receive a tiny, traceable intravenous dose to allow precise measurement. …

This early-stage study aims to understand how a common antifungal medication (itraconazole) affects the way the body processes a new experimental drug (HSK31858). It involves 24 healthy volunteers who will take both drugs in a specific sequence. The main goal is to measure the le…
