Filter by: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 mild cognitive impairment and dementia, but more evidence is needed to support the ability to effectively target the brain through intranasal routes. 12 healthy adults will be randomly assigned to receive a single dose of either 40 units ("low dose" group) or 80 units ("high dose" group) of insulin. Participants will undergo image-guided lumbar puncture (spinal tap) performed by a study radiologist. 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 the SipNose device to effectively deliver insulin to the central nervous system of humans as measured in the cerebrospinal fluid.
The purpose of this study is to investigate the effects of acute inorganic nitrate supplementation (with beetroot) on the regulation of sleep and neurovascular physiology.
This study is designed as a randomized, double-blind, parallel-group study to evaluate the PK, safety, tolerability, immunogenicity, and PD of TUR03 compared to Soliris, when administered as a single IV infusion in healthy adult male participants.
Blood flow restriction associated with resistance training is suggested to potentiate increases in muscular strength and hypertrophy. This study will compare the effects of resistance training associated with blood flow restriction with a regular resistance training program. Findings of this project will provide important information regarding a promising intervention to potentiate muscle performance.
The overall aim of this observational study is to investigate how individual differences influence the effects of mindfulness meditation to uncover for whom mindfulness is beneficial and for whom it may be harmful. The first objective is to identify the mechanisms underlying the effects of mindfulness meditation on mental health. The second objective is to examine how three candidate factors, namely trauma symptoms, tendency to dissociate, and repetitive negative thinking, influence the effect of mindfulness meditation on mental health. Adults who enrolled for a Mindfulness-Based Intervention (MBI) at the participating sites (n=120 for each site) will be invited to participate. Before the start of the MBI, after half of the sessions, at the end of the MBI and at 3-months follow-up, participants will complete self-report questionnaires. The main outcomes are symptoms of anxiety and depression, quality of life, wellbeing, and adverse effects resulting from the MBI. A subset of participants will be invited for a semi-structured interview after the end of the intervention.
This pilot study aims to leverage VR's capacity to easily replicate content and allow for multiple users to share the same space and engage in activities as if they're meeting in person. Integrating VR into afterschool programs will allow youth to receive more consistent programming content, even when they are unable to travel to the physical location for the in-person meetings.
The purpose of this study is to find out whether the nerve track function is helpful in distinguishing appropriate anatomical structures for beginners using ultrasound.
The objective of this study is collect urine samples from healthy adult subjects and subjects with stable chronic morbidities for future testing to serve as controls and establish reference ranges in the development of new invitro diagnostic devices.
This research study is being done to provide comparative data to the Mayo Clinic Adult Congenital Heart Disease Registry.
This is a study to collect data to build, evaluate and validate (test) a tool to infer/predict an estimated microbiome (community of microorganisms such as bacteria, fungi and viruses that exists in a particular environment) profile. The study will take place at several hospitals/clinics across Singapore, Malaysia, and Thailand.
