This study will measure cortisol in saliva from 220 healthy adults to establish normal reference ranges. Researchers will also determine the best cut-off values to diagnose Cushing's syndrome and adrenal insufficiency. The goal is to improve accuracy and ease of testing for these…

This early-stage study tests a new radioactive tracer called 68Ga-FC516 for PET/CT scans. It includes 10 participants—healthy adults and prostate cancer patients—to check safety, how the tracer spreads in the body, and how well it spots tumors compared to existing tracers. The go…

This study tests whether training with virtual reality (VR) can help college students improve their public speaking skills and feel less anxious. About 80 students will be randomly assigned to either VR training or a waitlist. Researchers will measure speech rate, pauses, voice c…

This study looks at two ways to help young athletes recover after intense exercise: TECAR therapy (a type of electrical heat treatment) and cycling at a light pace. About 48 healthy adults who do regular sports will do jumping exercises to get tired, then try one of the recovery …

This early-stage study tests how a new drug called DW4421 interacts with three common NSAID pain relievers (like ibuprofen) in 150 healthy adults aged 19 to 50. The goal is to check safety and measure drug levels in the blood. No treatment benefit is expected; it's about gatherin…

This study looks at how the shoulder tendon changes right after two different exercise programs. Researchers will use ultrasound to measure tendon thickness before and after exercise in 24 adults, some with shoulder pain and some without. The goal is to learn more about tendon he…

This study looks at how well a blood test can predict a person's fitness level, measured by VO₂max. Researchers will collect blood samples and fitness data from 250 healthy adults. The goal is to see if certain molecules in the blood can accurately estimate how fit someone is, an…

This study looks at how non-nutritive sweeteners (like those in diet drinks) affect blood sugar control, gut bacteria, and hunger hormones. Researchers will compare a 6-week period of consuming these sweeteners to a control period in 60 healthy adults aged 45-79. The goal is to u…

This study tests if a mild electrical pulse on the ear can improve decision-making and problem-solving. Researchers will include healthy adults, people with mild cognitive impairment, and those with Parkinson's disease. The goal is to understand how this stimulation affects brain…

This study tests whether AS01, an ingredient in the shingles vaccine, can act like a general trainer for the immune system, making it stronger against various infections. Researchers will give AS01 or a placebo to 40 healthy adults aged 21-59 and measure immune responses over 3 m…

This study tests whether a special nutritional supplement can increase NAD+, a molecule linked to energy and aging, in healthy adults aged 45 to 65. Participants will take either the supplement or a placebo for a set period. Researchers will measure NAD+ levels in the blood and a…

This study looks at how multiple sclerosis (MS) changes the way people walk. Researchers will use motion cameras, pressure mats, and wearable sensors to measure walking patterns in 30 people with MS and healthy adults. The goal is to better understand gait quality, not to test a …
