Filter by:This is a Phase 1, randomized, double-blind, single-center, placebo-controlled, sequential-cohort study in at least 60 healthy adult male and female subjects. Subjects in Cohorts 1 through 5 will be randomly assigned in an 8:2 allocation to receive active or placebo treatments. Subjects in Cohort 6 will be randomly assigned in a 1:1 allocation to receive an IV dose of nafithromycin and a single oral dose of nafithromycin in each crossover period. Subjects in each of Cohorts 1, 2, and 3 will receive a single dose of 100, 200, or 400 mg, respectively, of nafithromycin or matching placebo on Day 1.
Background: The Teen Health Information Literacy Project is an after-school program for high school students. It gives them skills to access valid and reliable health data. It also aims to grow young health advocates. Researchers want to find out more about the impact the program has had on students. They want to use this feedback to improve the program. Objective: To gain feedback about the Teen Health Information Literacy Project. Eligibility: Young people who participated in the Teen Health Information Literacy Project. The project was run by Area Health Education Centers (AHECs) and sponsored by the National Library of Medicine (NLM). Design: The study will be explained to students during a program session. They will take consent forms home to their parents. Participants will split into 6 focus groups. Each one will be conducted at an AHEC project site. The focus group will be a 90-minute discussion between participants and an evaluator from the NLM. The evaluator will be present either in person or by video conference. The evaluator will ask participants questions, which may include the following. What did they like and dislike about the program? Why did they decide to participate? What have they learned? Would they recommend this program to another student? How has the program affected their interest in health-related careers? The discussion will be audio-recorded. The evaluator will use an automated tool to convert recordings into text. After that, she will destroy the audio.
This study will assess the nutritional effect of cashews on LDL-C concentrations and secondarily on other aspects of the fasting lipoprotein lipid profile in healthy men and women with moderately elevated cholesterol.
The purpose of this study was to assess the safety, tolerability, and pharmacokinetic (PK) of TAK-071 when administered as single rising dose (SRD) and multiple rising dose (MRD) orally in healthy participants and participants with mild cognitive impairment (MCI) or mild Alzheimer disease (AD).
Balance disorders are sometimes treated with exercises performed on unbalanced surfaces. The "BOBO" system allows connection of a standing platform attached to any of these surfaces, to a screen, where the user can control games with his or her body movements. In this study, the lower limb muscle activity of healthy individuals will be monitored during different games in order to assert the the ability of each game in strengthening certain muscle groups.
Children's understanding of linear-order (e.g., Dan is taller than Lisa, Lisa is taller than Jess) and set-inclusion (i.e., All tulips are flowers, All flowers are plants) relationships is critical for the acquisition of deductive reasoning, that is, the ability to reach logically valid conclusions from given premises. Behavioral and neuroimaging studies in adults suggest processing differences between these relations: While arguments that involve linear-orders may be preferentially associated with spatial processing, arguments that involve set-inclusions may be preferentially associated with verbal processing. In this study, we use functional magnetic resonance imaging to investigate how and when these processing differences appear in children from 8 to 14.
This study will examine the safety of ascending doses of AB-SA01 when topically applied to intact skin of healthy adults.
This is a Phase 1, First-Time-In-Humans, randomized, placebo-controlled, double-blind, escalating single- and multiple-dose study to evaluate the safety, tolerability, and pharmacokinetics of CNM-Au8 in healthy male and female volunteers. There will be 2 phases to this study: a single ascending dose (SAD) phase and a multiple ascending dose (MAD) phase. The SAD Phase will be conducted first followed by the MAD phase of the study.
Background: Cellular senescence is the aging of cells. It is a complex process that may be connected with aging and age-related diseases. It is unknown if these cells appear around wound sites in humans a few days after skin injury and if there are differences in young and old individuals. This study is being done to look at how cells in your body respond to small skin wounds. This information may help treat age-related diseases. Objective: To study how cells in the body respond to small skin wounds. Eligibility: Healthy adults ages 20-39 or 70+ Design: Participants will be screened with medical history, physical exam, and blood sample. They will fast before the screening visit. Women will have a urine pregnancy test. Participants will have 3 study visits over about 3 weeks. Visits 1 and 2: Participants will fast before and have blood taken. Women will have a urine test. All participants will have 2 skin biopsies. A spot on the upper arm will be numbed. Two small pieces of skin will be removed. They will keep the area covered until the next visit. Visit 3: Participants will have their vital signs taken. Their biopsy wounds will be measured and photographed.
