Filter by:The purpose of this randomized crossover trial is determine whether acute consumption of blueberries with different proteins from plants (hemp or pea) or dairy (whey) impact the absorption of blueberry phytochemicals, which could impact the health benefits of blueberries. A secondary purpose is to understand the role that the gut microbiome may play, as well as the impact on urine polyphenol metabolites and potential implications for cardiometabolic health. Researchers will compare four arms: 1) Blueberries; 2) Blueberries + whey protein; 3) Blueberries + pea protein; and 4) Blueberries + hemp protein.
Background: Many kinds of good or normal bacteria live on your skin and inside your stomach and intestines (gut). These bacteria are important to your health. What you eat, where you live, and what medicines you take can affect the bacteria in your gut. Bismuth subsalicylate (BSS) is an ingredient in common medicines for mild diarrhea and stomach pain. Products that contain BSS include Pepto-Bismol, Kao-Tin, and Pink Bismuth. But how BSS affects the bacteria in a person s gut is not fully understood. Objective: To see how BSS affects gut bacteria in healthy people. Eligibility: Healthy people aged 18 to 50 years. Design: Participants will have 6 clinic visits in up to 16 weeks. Only 1 visit must be at the NIH clinic; others may be either in-person or remote. BSS is a liquid taken by mouth. Participants will take a dose of BSS 4 times a day for 2 days. They will take the same amount of BSS as a person would take to treat diarrhea or related problems. Stool samples will be collected at each study visit. For remote visits, participants will be given a collection kit; they will collect the sample at home and send it in. Participants will take surveys at each visit. They will answer questions about their diet and health. Participants may also provide optional samples of blood, saliva, and urine. Participants may have up to 2 optional colonoscopies. A long tube will be inserted via the rectum to collect tissue samples from the intestine. Participants will be sedated or placed under anesthesia for the procedure.
A Phase 1, Open-label, One-sequence Crossover Study to Investigate the Effect of a Breast Cancer Resistance Protein Inhibitor on the Single-dose Pharmacokinetics of Adagrasib in Healthy Adult Subjects
Cerebrovascular accident makes adults lose the ability to be independent in daily life, and a higher proportion of them will suffer from dysphagia. Previous studies pointed out that the tongue muscle strength of stroke patients is significantly lower than that of healthy adults. Furthermore, the tongue strength of stroke patients with dysphagia is significantly lower than those without dysphagia. Many studies investigated the performance of tongue function in healthy adults or groups with dysphagia caused by different diseases. However, the current research on the performance of tongue function in healthy adults and stroke patients in Taiwan is relatively lacking. Therefore, our purpose of this study is to investigate the performance and differences of tongue function between healthy adults and strokes patients in Taiwan. This study is expected to recruit 32 healthy adults and stroke patients in each group. The two groups will be matched with each other by gender and age (±2 years). In the study, Mann assessment of swallowing ability (MASA) will be used as an assessment tool to distinguish whether the subjects are accompany with dysphagia and the severity of dysphagia. And using Iowa Oral Performance Instrument (IOPI) to measure the value of tongue pressure. Then, analyze whether there are significant differences and the correlations. To provide clinicians with empirical data for early detection and intervention of swallowing.
The aim of this research is to develop protocols that selectively target and improve speech-motor learning processes. Participants will be asked to name pictures, read words/sentences, and listen to sounds while their speech signals will be collected during the study.
(1) Maximum respiratory pressure (MRP)1) Maximum inspiratory pressure (maximum intake pressure) and maximum expiratory pressure (MEP) Digital spirometer (Pony FX, COSMED Inc., Italy) are used to measure the micro-paste in a seated position. MIP is based on the pressure maintained for at least 1 second, inhaling or exhaling with maximum effort in the maximum exhalation state (=residual volume) and the maximum exhalation state (=total lung capacity). The maximum positive pressure value of the MEP and the minimum sound pressure value of the MIP are selected among the three or more attempts. 2) Using the MVV (maximum volitional ventilation) Digital spirometer (Pony FX, COSMED Inc., Italy) machine, repeat breathing deeply and quickly for 12 seconds while wearing a nose plug, and multiply it by 5 to obtain the L/min value. (2) Measure the values of the Pneumatic ventilation. · FVC (forced vital capacity): Total expiratory volume of one of the maximum effort gases · FEV1 (forced expiratory volume 1, effort expiratory volume): Ejected expiratory volume of the first second of the maximum effort expiratory volume (FEV1/FVC): FVC ratio, percentage of FVCs, and extraction of the FVC (excessive flow). PEF): Highest speed of effort opportunity
A Phase 1, Open-label, Multiple-dose, One-sequence Crossover Study to Investigate the Effect of Repeated Oral Doses of a Strong CYP2C8 Inhibitor on the Steady-state Pharmacokinetics of Adagrasib in Healthy Adult Subjects
This is a randomized, double-blind, placebo-controlled, study to assess the safety and effects of CHI-560, CHI-563, CHI-564, & CHI-565 versus placebo on sleep quality in healthy adult participants ages 18-55 years.
The Seattle Dietary Biomarker Development Center (S-DBDC) aims to advance the science of measuring dietary intake by identification and validation of dietary biomarkers that improve upon self-reported diet. To accomplish this mission, the Seattle DBDC will carry out controlled feeding studies in healthy human volunteers. Metabolomics assays will be conducted on blood and urine specimens collected during the feeding studies for biomarker identification.
This is a double-blind placebo-controlled cross-over trial that aims to determine the acute effect of beetroot juice ingestion on isometric knee extension strength, explosive strength and local muscular endurance.
