Filter by:The investigators will evaluate a computer-animated character that explains medical illustrations to people, comparing the character to having people understand the illustrations on their own, and also comparing the computer character on a computer display to one in immersive virtual reality. The investigators will determine which method leads to the best understanding and lowest anxiety.
A Phase 1 Study to evaluate the safety, PK/PD, drug-drug interaction(DDI) of Epaminurad and Naproxen in Healthy Volunteers
The purpose of this study is to find out whether insulin, a drug approved by the FDA for the treatment of diabetes mellitus, reaches the brain and spinal cord when delivered as a nasal spray (intranasally). Intranasal insulin has been shown to improve memory and mood in patients with neurological diseases such as mild cognitive impairment and dementia, but more evidence is needed to support the ability to effectively target the brain through intranasal routes. 18 healthy middle-aged adults will be randomly assigned to receive a single intranasal dose of 40 units insulin ("low dose" group), 80 units insulin ("high dose" group), or saline (placebo, or control group). Participants will undergo an image-guided lumbar puncture (spinal tap) performed by a study clinician. Samples of cerebrospinal fluid (a fluid surrounding the brain and spinal cord) and blood will be collected at 5 timepoints during the lumbar puncture: once prior to the administration of intranasal insulin, and again at 10, 20, 30, and 40 minutes after the dose is given. Samples will be tested to determine the level of insulin detected in the cerebrospinal fluid and blood at each time point. Results of this study will provide essential information about the ability of insulin to reach the brain after intranasal administration.
The accumulation of senescent cells with age is a central mechanism that contributes to the development of chronic diseases, primarily by driving systemic chronic inflammation. Senolytic compounds such as fisetin can selectively target senescent cells for elimination and reduce multiple age-related pathologies in animal models. We will conduct a clinical trial in healthy volunteers and older patients with multiple chronic diseases. The participants will receive fisetin or placebo for two days, after which they will be examined at regular intervals for up to three months. We will investigate how fisetin is absorbed and metabolized by the body, and whether fisetin is safe. We will also identify methods to best measure the effect of fisetin on chronic inflammation, senescent cells, and general health.
Masters level cyclists are a population above the age of 35 years who frequently participate in prolonged as well as heavy-volume training. Like most endurance-trained athletes, a greater recommended dietary allowance (RDA) for protein of 1.2-1.4 g/kg/bw is suggested. Dietary protein intake is vital for maximizing the benefits of training and ensuring optimal recovery. Dietary recommendations traditionally have been determined through nitrogen balance techniques, however, recent research indicates how this method is potentially underestimating protein requirements. Therefore, there is a need to reassess current dietary recommendations in order to meet the demands of physical activity for highly active populations. Recent efforts to understand protein requirements during rest and following exercise have been completed using the indicator amino acid technique (IAAO). This non-invasive method is reported to provide a robust measure of protein requirements. However, there is limited work in older (≥60 years) active populations. The purpose of this study is to measure the protein requirements in master cyclists, following an endurance training session, using the non-invasive IAAO technique.
This study aims to conduct a 24-week intervention involving formula milk powder for middle-aged and elderly individuals, assessing its impact on body composition and physical performance in comparison to interventions using regular milk powder and individuals without intervention.
The main objectives of this trial are to investigate safety, tolerability and pharmacokinetics (PK) of BI 3731579 in healthy male subjects.
This study examines the role of craniofacial dimensions and self-evaluation thereof in the protection afforded by masks commonly worn by the public as protection against aerosol contaminants. The effectiveness of instructions for self-evaluation of craniofacial dimensions will be tested against standard digital and manual craniometric methods. Approximately 500 (18-70 year old) subjects of any gender. After consenting to participate in the study, subjects will use a short self-assessment questionnaire to measure their craniofacial dimensions, and have their face measured using standard anthropological techniques and a 3D camera. They will then enter a chamber containing an atmosphere of aerosolized salt particles where the fitted filtering efficiency of 2 types of face masks will be measured briefly. Participation time is approximately 60 minutes.
Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide, and the non-Hispanic Black (NHB) population is disproportionately affected. Our research has previously demonstrated that oxidative stress may contribute to reduced vascular function in otherwise healthy NHB adults, potentially predisposing them to the development of hypertension and CVD. This study is designed to examine whether the mitochondria are an important source of oxidative stress-induced vascular dysfunction in healthy NHB adults.
This study includes an open label clinical trial comparing two doses of CoQ10 for 8 weeks to improve fatigue among patients with Crohn's disease and a prospective cohort study of healthy controls taking CoQ10 for 2 weeks. Additionally, among 15 participants who do not meet the fatigue threshold for the open label trial, the investigators will measure CoQ10 levels in blood and fasting urine, as well as complete the same data collection. Hypotheses 1. Fatigue will improve with CoQ10 and there will be a dose response with greater improvement with higher dose as measured by the Patient Reported Outcomes Measurement Information Systems Fatigue PROMIS Fatigue 7a instrument. 2. Fatigue will improve when measured with other fatigue scales in a similar dose dependent manner and that general and physical fatigue will improve more than mental fatigue. 3. CoQ10 will improve quality of life as measured with the short Inflammatory Bowel Disease Questionnaire (sIBDQ).
