The goal of this clinical trial is to understand how many individuals who previously participated in the Indiana Biobank will return a type 1 diabetes home screening kit based upon different methods of recruitment communication. The main question it aims to answer is: What form of recruitment communication is most effective for completing a type 1diabetes home screening kit? Researchers will compare two types of recruitment contact: email and mail based communication (low-touch) versus phone contact and follow-up by a research team member (high-touch). Participants will be contacted either via email/mail or by phone and asked if they want to complete a type 1 diabetes home screening kit.

The goal of this clinical trial is to learn how nicotinamide riboside (NR), a form of vitamin B3, affects brain energy metabolism in healthy adults. Researchers want to find out if taking NR by mouth for 2 weeks can raise the balance of two related brain chemicals called NAD+ and NADH, which play a key role in how cells make and use energy. The main questions are: Does short term NR treatment increase the NAD+ to NADH ratio in the brain, and does it change other brain energy measures that we can see with a special type of MRI scan called phosphorus 31 MR spectroscopy. Adults between 18 and 65 years old who are generally healthy and do not have a personal or close family history of mood or psychotic disorders may be able to take part. People who join the study will first have a screening visit with a psychiatric interview and safety checks to confirm they are eligible and to review the risks and procedures. Eligible participants will then have a baseline visit that includes a blood draw, vital signs, urine drug and pregnancy tests when needed, and a 7 Tesla MRI/MRS scan focused on brain chemistry and structure. After the baseline visit, participants will take NR capsules by mouth at home, 1500 milligrams in the morning and 1500 milligrams in the early afternoon each day, for about 2 weeks, for a total daily dose of 3000 milligrams. They will be asked to avoid alcohol and other drugs during the study and to complete a short food diary near the end of the dosing period so that researchers can track diet. On the last day of taking NR, participants will return for repeat MRI/MRS scans, blood tests, and vital signs so that researchers can compare brain and blood measures before and after NR treatment. Researchers will compare each participant's brain NAD+ to NADH ratio and other bioenergetic markers before and after NR to see if NR changes these measures in a consistent way. If NR raises brain NAD+ and improves measures of energy metabolism in healthy adults, this may provide important background information for future studies that test whether NR can help people with psychiatric or neurological disorders linked to mitochondrial dysfunction and oxidative stress. There is no expected direct health benefit for participants, but their involvement may help improve understanding of how NR affects human brain metabolism.

This observational study aims to determine whether ultrasound-derived muscle biomarkers can predict isometric quadriceps muscle strength and handgrip in healthy adults aged 18-89 years. The main questions it aims to answer are: * Which ultrasound muscle characteristics are associated with isometric quadriceps muscle strength and handgrip? * Can ultrasound-derived biomarkers be used to develop predictive models of muscle strength in healthy adults? Participants will undergo: * Ultrasound assessment of the quadriceps and forearm flexor muscles; * Measurement of isometric quadriceps muscle strength and handgrip using standardized dynamometry protocols; * Assessment of functional capacity, mobility and balance; * Completion of questionnaires related to health status, physical activity, nutrition, fatigue and health-related quality of life. The study will also assess the reliability of ultrasound measurements and explore the relationship between ultrasound variables, muscle strength, physical function and health-related factors.

As people grow older, their immune system - the body's natural defence against diseases - becomes weaker, making them more vulnerable to infections and less responsive to vaccines. This was clearly seen during the COVID-19 pandemic, where older adults were more likely to develop severe illness. Researchers have made an interesting discovery about AS01, an ingredient already used in successful vaccines like the shingles vaccine. They found clues that AS01 might work like a general fitness trainer for the immune system, potentially making it stronger and better at fighting off various types of infections, not just specific ones. To confirm this possibility, we are conducting this research study with adults aged 21-59 to test whether AS01 by itself can boost and train the immune system, how long this boost lasts, and if it actually helps you fight off other infections more effectively.

This study aims to analyze the effects of an 8-week strength training program combining different exercise intensities and blood flow restriction (BFR) conditions on safety, tolerability, muscle adaptations, and physical performance variables. Three training modalities will be compared: 1) high-intensity exercise with BFR therapy; 2) low-intensity exercise with BFR therapy; and 3) high-intensity exercise without BFR therapy. All groups will perform the same exercise modality, differing only in intensity and the application of BFR. Participants will be randomly assigned to one of the three groups and will undergo a 8-week intervention. The variables of interest will be assessed in each group for subsequent analysis and comparison.

Sensorimotor function of the upper limb is commonly impaired after stroke, even in the chronic phase (\>6 months post-stroke). Nevertheless, good sensorimotor function is needed for daily life functioning. Sensorimotor function can be divided into three components: exteroception, proprioception and sensory processing. It is important that those three components will each be addressed in the upper limb rehabilitation. Unfortunately, there is still no optimal therapy to address sensory processing. Therefore, the investigators developed an intensive sensorimotor robot-based rehabilitation paradigm (called ROBUST) with focus on sensory processing. As a first step, the investigators did a pilot study (S69003) including 10 persons with chronic stroke to investigate the potential effectiveness and feasibility of this novel rehabilitation. The median change score of motor, sensory and sensorimotor assessments was exceeding the minimal clinical important difference (MCID), and the total amount of therapy was feasible as well. The investigated protocols to measure potential changes in brain function (activity and connectivity) and structure accompanying the novel therapy appeared feasible as well. Based on this first pilot study, the investigators finalized the protocol for this RCT to investigate the effectiveness of the ROBUST intervention.

Preeclampsia and eclampsia are among the leading causes of maternal death and morbidity, and are obstetric emergencies that lead to serious complications during pregnancy. Preeclampsia affects 2-8% of pregnancies worldwide; approximately 46,000 maternal deaths and approximately 500,000 fetal or neonatal deaths occur annually due to preeclampsia. This situation highlights the importance of well-equipped midwifery care, especially in terms of early diagnosis, accurate assessment, emergency intervention, and effective management. Traditional teaching methods alone are insufficient for midwifery students to develop clinical decision-making skills in life-threatening situations such as preeclampsia and eclampsia, and to translate theoretical knowledge into practice. Therefore, new teaching approaches that support active learning, interaction, and decision-making processes in education are needed. In recent years, digital game-based learning has emerged as an innovative tool in health education with its potential to attract learners' attention, improve problem-solving skills, and increase their motivation. Especially for midwifery students, digital games facilitate experiential learning by providing a safe simulation environment in preparation for information overload and stressful clinical environments. However, the use of digital games in teaching complex clinical processes such as preeclampsia and eclampsia management has been researched to a limited extent. Scientifically examining the effects of such innovative methods on students' learning motivation, attitude, and active participation in the learning process in midwifery education will fill an important gap in the literature. In this context, evaluating digital game-based learning in preeclampsia-eclampsia management education by comparing it with simulation training and traditional teaching will make a significant contribution to both the midwifery education literature and the knowledge base regarding the use of technology in health education.

The purpose of this study is to understand how different areas of the cerebellum (a part of the brain) control different functions and how they can be influenced by non-invasive brain stimulation. While researchers know that repetitive Transcranial Magnetic Stimulation (rTMS) can have positive effects on conditions like stroke and schizophrenia, they do not yet fully understand which specific stimulation settings work best or which exact parts of the cerebellum should be targeted for different symptoms. This study compares the effects of stimulation on two specific regions: * Lobule VIII: Linked to movement and motor learning. * CRUS I/II: Linked to attention, thinking (cognition), and predicting the timing of events.By comparing these areas, researchers hope to gain the information needed to develop better treatments for neurological and psychiatric disorders. This is a randomized, double-blind study involving 40 healthy volunteers. Participants will be split into two groups: * Group 1: Receives "exciting" (activity-increasing) stimulation. * Group 2: Receives "inhibiting" (activity-decreasing) stimulation. Each participant will attend three different test sessions in a random order: * rTMS targeting Lobule VIII * rTMS targeting CRUS I/II * Placebo (Sham) stimulation that looks and feels like the real thing but does not affect the brain. During each session, researchers will use brain imaging (fMRI) and computerized tasks to measure changes in brain connectivity and performance in motor and cognitive activities. There is no direct medical benefit to the participants. However, the results will help scientists create better therapies for patients with brain-related health issues The risks are considered minimal. Common side effects of rTMS include temporary mild headaches or a clicking sound during stimulation. MRI scans can sometimes cause mild discomfort or a feeling of closed-in spaces (claustrophobia). Researchers have put safety measures in place, such as hearing protection and constant medical supervision during scans, to minimize these risks.

Objective: This study aims to compare the effects of two techniques-foam rolling (FR) and therapeutic massage-on reducing the muscle tone in the calf muscles (gastrocnemius and soleus) of healthy individuals. Methods: A randomized, controlled crossover design was used with 40 healthy participants (aged 18-45). Participants were randomly assigned to either a foam roller or a therapeutic massage group. The interventions were applied to the dominant leg, and muscle tone was measured pre- and post-intervention using a MyotonPro device. The primary outcome was muscle tone (Hz), and secondary outcomes included muscle stiffness (N/m) and elasticity (D \[log\]). Results: The study will assess the effectiveness of each intervention on muscle tone, stiffness, and elasticity. It aims to determine whether foam rolling is as effective or superior to traditional massage in reducing calf muscle tone. Conclusion: This research will contribute to understanding the efficacy of foam rolling as a self-administered technique for muscle tone reduction and its potential application in clinical and athletic settings

Every individual will participate in both exercise programs separated by up to 15 days. The researcher will evaluate the shoulder tendon using ultrasound before each exercise program and at 1 hour, 6 hours and 24 hours after each exercise program. The researcher will also evaluate self reported pain, pain sensitivity testing, and self reported questionnaires. We will compare the tendon changes after each exercise program, as well as between participants with and without shoulder pain.

This Clinical trial is being done to understand how food and a common stomach-acid reducing medicine (called a proton pump inhibitor-PPI) affect how the body absorbs a new drug, VRN101099, in healthy adults. Researchers will measure how much of the drug gets into the bloodstream and how fast it gets there in each situation. This will help identify the most effective way for future patients to use VRN101099 in the treatment of solid tumors and cancers. The main questions it aims to answer is: 1. Does food or a PPI change how the body absorbs a single dose of VRN101099? 2. Is a single dose of VRN101099 safe and well tolerated when taken with or without food or a PPI? 3. How is VRN101099 removed through urine when taken with or without food or a PPI?

The goal of this clinical trial is to compare two recovery methods after fatigue in young athletes. It aims to find out if tecar therapy (TECAR) or cycle ergometer exercise can improve recovery after intense physical activity and help athletes return to their normal performance more quickly. The main questions it aims to answer are: Does TECAR or cycle ergometer improve physical performance after fatigue? Do these methods reduce muscle pain and soreness after fatigue? Researchers will compare TECAR with active recovery using a cycle ergometer to see which method is more effective. Participants will: Perform a series of jumps to induce fatigue Be randomly assigned to one of the recovery methods Complete physical tests before and after fatigue Undergo simple measurements of muscle condition and pain Report their level of effort and muscle soreness

Exercise-induced hypoalgesia (EIH) refers to the reduction in pain sensitivity following acute exercise. Although aerobic exercise has been shown to induce hypoalgesia in healthy individuals, it remains unclear whether the magnitude of this response differs between men and women. This quasi-experimental study aims to evaluate sex differences in pressure pain thresholds following a standardized aerobic exercise protocol using a lower-limb cycle ergometer. Pressure pain thresholds will be assessed before exercise, immediately after exercise, and 30 minutes after exercise in healthy adults aged 18 to 65 years. The findings of this study may contribute to improving individualized exercise prescription strategies based on sex differences in pain modulation.
