This study looks at how a gentle, non-invasive brain stimulation technique called rTMS changes the way the stomach and gut work. Researchers will measure stomach electrical activity, heart rate, and how much liquid people can drink before feeling full. The goal is to learn more a…

This study tests whether mild electrical stimulation of the outer ear can activate the vagus nerve, a key nerve controlling stomach function. Researchers will measure nerve activity in 30 healthy adults using skin electrodes. The goal is to learn how to study this nerve better, w…

This study looks at how eating salt changes the way our genes control blood pressure. Researchers will test 88 healthy adults aged 25-45 to see how their bodies respond to salt and a hormone called angiotensin II. The goal is to understand why some people are more salt-sensitive,…

This study looks at how the antifungal drug itraconazole changes the way the body processes HSK31858. It involves 24 healthy adults aged 18-45. Participants take HSK31858 with and without itraconazole to measure drug levels in the blood. This is a drug interaction study, not a tr…

This study tests a special education program that combines hypnobreastfeeding ideas with a motivation and skills model. It involves 80 first-time pregnant women to see if the program improves their breastfeeding knowledge, self-confidence, and motivation. The goal is to help new …

This study looks at how the drug rifampicin changes the way another drug, HSK31858, is processed in the body. It involves 24 healthy adults aged 18 to 45. The goal is to measure drug levels in the blood, not to treat any disease.
