This observational 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 (too much cortisol) and adrenal insufficiency (too little cortisol). The g…

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. 80 students will be randomly assigned to either VR training or a wait-list group. Researchers will measure speech rate, pauses, voice …

This study looks at two ways to help young athletes recover after intense exercise: TECAR therapy (a type of heat treatment) and cycling. About 48 healthy adults who do regular sports will do jumps to get tired, then try one recovery method. Researchers will measure jump height, …

This study tests a new type of sensor that can detect brain activity without touching the skin. Researchers want to see if these sensors can pick up clear signals and filter out background noise. The goal is to learn how well the technology works for future hands-free devices. Th…

This study tests if a gentle 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 see if this safe, non-invasive method can b…

This study looks at whether AS01, an ingredient used in some vaccines, can act like a general trainer for the immune system, making it stronger against various infections. Researchers will give AS01 to healthy adults aged 21-59 and measure immune responses over 3 months. The goal…

This study looks at how non-nutritive sweeteners (like those in diet drinks) affect blood sugar control, gut bacteria, and hunger hormones in healthy adults aged 45-79. Over 6 weeks, participants will consume sweeteners or a control, and researchers will measure changes using glu…

This study looks at how well blood tests can measure fitness in healthy adults. Researchers will measure participants' maximum exercise capacity and collect blood samples to find connections. The goal is to develop a blood-based way to estimate fitness without needing a treadmill…

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 understand normal tendon r…

This early-stage study tests how a new drug, DW4421, interacts with three common NSAID pain relievers in 150 healthy adults aged 19-50. The goal is to measure safety and how the drugs affect each other's levels in the body. Participants must be in good health and within a specifi…

This study tests whether a special nutritional supplement can increase NAD+ levels in healthy adults aged 45 to 65. Participants will take the supplement or a placebo for a short time, and researchers will measure NAD+ and related substances in their blood. The goal is simply to …

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 in 30 adults with MS and healthy volunteers. The goal is to better understand gait problems, not to test a trea…
