Filter by:Diets low in seafood omega-3 polyunsaturated fatty acids (PUFAs) are very prevalent. Such diets have recently been ranked as the sixth most important dietary risk factor-1.5 million deaths and 33 million disability-adjusted life-years worldwide are attributable to this deficiency. Wild oily fish stocks are insufficient to feed the world's population, and levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in farmed fish have more than halved in the last 20 years. The primary objective of this randomised, double-blinded, controlled nutritional trial will be to test if consumption of at least 4 servings of omega-3 PUFA-enriched chicken-meat and 4 enriched eggs per week, over a 4-month period, results in measurably higher blood levels of EPA and DHA in healthy Saudi adults. This will be a randomised double-blind interventional study. Eighty adult male and female participants (age ≥ 18 years of age) will be asked to eat at least 4 portions of omega-3-PUFA enriched (or control) chicken-meat per week, and at least 4 omega-3-PUFA enriched (or control) eggs per week, for 4 months. Participants will be assessed at baseline and at monthly intervals for 4 months. Assessments at these visits will include; comprehensive lifestyle and medical history; food frequency questionnaire; 3 days food record; height, weight, waist and hip circumferences; blood sampling; participant well-being and adverse events. Measurement of plasma and red blood cell levels of EPA, DHA and Docosapentaenoic acid (DPA) will be performed at baseline and at study end using gas chromatography-mass spectroscopy. The primary end point will be the change in red blood cell omega-3-index (sum of EPA and DHA expressed as percentage of total fatty acids in erythrocyte membranes) at 4 months. The nutritional trial will be analyzed on an intension to treat basis. Repeated measures ANOVA will be used to compare the two study groups. The study will be reported in accordance with the CONSORT (Consolidated Standards of Reporting Trials) 2010 statement.
The purpose of the study is to assess the safety, tolerability and pharmacokinetics of XH-S002 in healthy volunteers under SAD (Single ascending dose) and MAD (Multiple ascending dose) studies. In addition, this study evaluates the food effects of XH-S002.
This study aims to compare the effects of mirror therapy combined with either neuromuscular electrical stimulation or binaural beat stimulation on post-stroke lower limb motor function recovery. The study also explores the relationship between patients' cortical excitability and motor function improvement.
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.
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.
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.
The primary objective of this study is to define the intracardiac flow imaging biomarkers in cardiac amyloidosis.
This is a Phase 1, randomized, double-blind study to assess the safety, tolerability, and effects of CHI-554 when co-administered with alcohol.
The purpose of the study is to assess vascular function in African Americans, Hispanic and Caucasian Americans to better understand racial differences in cardiovascular health. The investigators will further investigate the affect of Beetroot juice on the vascular function of all participants.
