Filter by:According to a recent consumer poll, over 20 million Americans regularly use cannabidiol (CBD). Moreover, 64 million Americans (over 25% of the population) report trying CBD at least once within the previous 2 years. Since the passing of the 2018 Agriculture Improvement Act, the use of hemp-derived products, such as CBD, is highly prevalent across North America. The acceleration of the use of CBD has outpaced our understanding of the associated potential risks and benefits, and the way it is processed within the body. In the current proposed project, investigators wish to continue our ongoing collaboration with Caliper Foods, a Colorado-based manufacturer of CBD products. The focus of this project is three-fold: (1) investigators will compare the pharmacokinetics of different formulations of ingestible CBD; (2) investigators will examine the potential two-way interaction between a meal and one formulation of ingestible CBD; and, (3) investigators will examine the influence of different formulations of CBD on markers of liver function.
An adequate quantity of lean body mass is vital for optimal health and performance, and is accrued when net protein balance (NPB) is positive. Amino acids are the building blocks of protein, and when consumed following resistance exercise, significantly improve NPB. However, no study has investigated how a supplement of all of the essential amino acids (EAA) affects NPB following resistance exercise in a free-living, home-based setting, particularly when compared to a supplement of branched-chain amino acids (BCAA). Therefore, the purpose of this study is to determine the impact of a novel EAA supplement on anabolism (e.g., NPB) as compared to BCAA and placebo supplements following home-based resistance exercise.
The PREDICT 3 study will build on previous research in over 2,000 individuals to further refine machine learning models that predict individual responses to foods, with the aim of advancing precision nutrition science and individualized dietary advice. The study incorporates both standardized and controlled dietary intervention, for the purpose of testing postprandial responses to specific mixed meals, in addition to a free-living period with a dietary record for measuring responses to a large variety of meals consumed in a realistic context, where the role of external factors (e.g. exercise, sleep, time of day) on postprandial responses may be determined. For the first time this PREDICT study is built on top of a commercial product which will allow access to a much larger group of participants who are already collecting large amounts of data through digital and biochemical devices that can contribute to science.
The primary objective of this study is to quantify miR-1 release from muscle in extra-cellular vesicles following an acute resistance exercise bout and potential delivery to subcutaneous adipose tissue in young healthy and obese adults.
The overarching aim of this proposal is to examine the feasibility of the Q-NRG+ indirect calorimetry device and its agreement with (Vmax) Encore indirect calorimetry device in mechanically ventilated children. The overall hypothesis of this study is that the Q-NRG+ will provide minute-to-minute oxygen consumption (VO2) and carbon dioxide production (CO2) measurements that are in agreement with those obtained by the standard indirect calorimetry device currently used at our institution (Vmax Encore).
The specific hypothesis is that the consumption of 2 Hayward green kiwifruit (containing actinidin protease) prior to 100g of ground beef will increase the rate of protein digestion from the beef in the elderly, leading to an increased uptake of the essential amino acids. Furthermore, this increased essential amino acid availability will produce a greater postprandial net anabolic protein response, as well as increased fractional synthetic rates of muscle proteins.
This is an open-label, fixed sequence study of the effect of probiotics supplementation on drug, vitamin, and hormone metabolism.
The purpose of this research is to determine the production of trimethylamine-N-oxide (TMAO) from different forms of choline and whether this response is modified by the gut microbiota composition.
The purpose of this randomized, double-blind, crossover study is to investigate the effects of Bang® Keto Coffee on resting and post-exercise metabolism and muscular performance during lower body resistance exercise.
Before inclusion in the trial. Careful medical history and medication use will be asked. Once included, 5 healthy subjects non-invasive ventilation(V60, Philips, Eindhoven, The Netherlands) will be administered at a level of positive end expiratory pressure (PEEP) of 4 cmH2O and without additional inspiratory support. Inspiratory support will then increase by 2 cmH2O every 2 minutes until 8 cmH2O is achieved for 2 minutes. The energy expenditure is measured using indirect calorimetry (Q-NRG®, Cosmed, Italy). To measure respiratory effort, the reversed RPE-scale was created for the purpose of the study. It uses the validated "rate of perceived exertion" scale (RPE-scale) which was altered by adding a reversed part. This could result in a score of -10 (no respiratory effort) until +10 ( maximal respiratory effort) where 0 represents the basal respiratory condition. Monitoring of heart rate, blood pressure and cardiac output will be done ( Nexfin®, BMEYE, Amsterdam, The Netherlands). After termination of the study clinical observation by principal investigator or co-investigator will be done for 15 minutes or until all side effects have worn off. If no side effects are observed, subjects will be released.
