This study tests whether a simple foot exercise called the soleus pushup can improve cholesterol, blood sugar, and hormone levels in people with thyroid problems, high blood pressure, or diabetes. Participants will perform the exercise, and researchers will measure changes in blo…

This study tests whether a mild electrical pulse to the ear (taVNS) can change how the brain and stomach interact in people with chronic indigestion or gastroparesis. Researchers will use brain scans and stomach electrical readings to see if the stimulation helps. The goal is to …

This completed study tested whether a topical serum containing Mitopure is safe for healthy adults. Forty participants applied the serum repeatedly over two weeks. Researchers checked for skin irritation and asked about product traits. The trial focused only on safety, not on whe…

This study tested whether taking a probiotic called Bifidobacterium animalis subsp. lactis Bi66 every day for 8 months can improve bowel function in healthy adults who have fewer than 5 bowel movements per week. 117 participants took either the probiotic or a placebo and recorded…

Medical students often feel stressed and anxious but have little time to relax outdoors. This study tested whether watching a 360-degree VR video of a nature scene for just 15 minutes could help. 82 students viewed either a familiar local scene or an overseas scene twice over two…

This study tests whether codeine can be detected in fingerprint sweat as accurately as in oral fluid. Forty healthy adults will receive two doses of codeine, and researchers will compare the results from both sample types. The goal is to find the best cutoff level for fingerprint…

This pilot trial is testing whether a proprietary nutritional supplement can increase levels of NAD+, a molecule important for cellular energy and aging, in healthy adults aged 45 to 65. Participants will take either the supplement or a placebo daily for 60 days. The study aims t…

This study uses video-based movement tracking to measure how people walk after a stroke — both in the clinic and at home. Researchers want to see if walking improvements made in therapy actually carry over into everyday life. The study includes stroke survivors and healthy adults…

This study tests whether a new food questionnaire (BTS-Salt) and a single spot urine sample can accurately estimate daily sodium intake in healthy adults aged 19–64. Participants will complete the questionnaire, provide a 24-hour urine collection (the gold standard), and give a s…

This trial tests whether eating avocado with a breakfast of bread and jam can improve how the body handles blood sugar and signals hunger or fullness afterward. Thirty healthy adults will compare three different breakfasts — one with avocado, one with added fat and fiber to mimic…

This early-phase trial is testing the safety and how the body handles an experimental drug called DA-5223 compared to a reference version. It involves 12 healthy adults who will receive single doses in a crossover design. The main goal is to measure drug levels in the blood and c…

This study tests three different force levels (2 kg, 5 kg, and 11 kg) of the 'crossed hands' myofascial release technique on healthy adults. The goal is to see how each force affects muscle stiffness, thickness, pain sensitivity, and lower back and hip mobility. By finding the mo…

This study looked at whether adding strength training to regular cycling workouts helps competitive cyclists improve performance and muscle function. Twenty-four male cyclists either did strength training plus endurance training or just endurance training for 10 weeks. Researcher…

This study looked at 80 healthy, active men aged 20-30 to see how leg muscle strength relates to anaerobic power—the ability to perform short, intense efforts like sprinting. Participants had their leg strength measured with a special machine and did a 30-second cycling test. The…

This small pilot study tested whether healthy adults could safely and comfortably exercise on a treadmill with their eyes closed, compared to a normal eyes-open session. Forty participants completed four treadmill workouts, two with eyes closed and two with eyes open. The study m…

This study tested a new type of sensor that can detect brain activity without touching the body. Five healthy adults took part to see if the device could pick up their brain signals and tell what they intended to do. The goal was to understand how well the technology works for fu…

This completed study tested whether a collagen-based material causes allergic skin reactions in 5 healthy adults. Researchers applied the material using a standard skin prick test and measured the size of any skin reaction. The goal was to see if the material is safe for future m…

This completed study tested whether a collagen-based material causes skin irritation or allergic reactions. Thirteen healthy adults wore patches with the material on their skin repeatedly. Researchers checked for redness, swelling, or other signs of irritation using a standard gr…

This study tested whether taking astragalus extract daily for 10 weeks could help reduce muscle soreness and inflammation during intense weight training. Twenty-four moderately active young adults took either the supplement or a placebo while following a structured workout progra…

This study looked at how a person's brain state (what they are thinking or doing) changes the brain's response to a type of non-invasive brain stimulation called rTMS. Thirty-six healthy adults received stimulation while their brain activity was measured with a special imaging te…

This study looked at 119 healthy young adults to find out what factors affect their balance. Participants completed various balance tests, and researchers measured foot posture, body composition, muscle strength, and cognitive performance. The goal was to identify which of these …

This study aimed to create a visual guide to skin aging by taking detailed 3D images of collagen in the skin of 250 healthy women aged 20 to 75. Using a special camera called LC-OCT, researchers measured collagen density and structure without any needles or surgery. No treatments…

This study tested whether catching objects guided by a real drone or a virtual drone in mixed reality could improve eye-hand coordination and thinking skills in healthy adults aged 60 and older. Thirty-eight participants completed both real and virtual catching tasks, and researc…

This study looked at how many medical students have immunity against hepatitis B and varicella-zoster (chickenpox) viruses. Researchers tested 401 students to see their protection levels and vaccination rates. The goal was to understand if current immunization programs are workin…
