Nutrient Profile and Muscle Protein Synthesis in Response to Corn Bread Made From Refined Versus Whole Grain Maize Flour

The purpose of the study is to quantify and compare the serum nutrient and hormonal profile, and muscle protein synthesis rates, in response to consuming isonitrogenous amounts of a traditional East African meal, mung bean stew with a traditional African corn bread made from two different kinds of maize (whole corn flour or refined). Specific aim 1: Describe the post-prandial nutrient and hormonal profile in serum in the 3 hours following consumption of a portion of mung bean stew with traditional African corn bread made with either whole grain maize flour or refined maize flour. Specific aim 2: Compare the ability a portion of mung bean stew and traditional African corn bread made with either whole grain maize flour or refined maize flour to activate mTORC1-specific and whole muscle protein synthesis in an in vitro model of muscle.

Nutrient and Hormonal Profile and Muscle Protein Synthesis Response to Consuming Chicken

The study aims to evaluate if there is a difference between eating conventionally raised or organic chicken. The investigators will measure and compare the nutrient and hormone levels in the participant's blood and the muscle protein synthesis rate (the rate at which your body builds muscle) after eating chicken from different farming practices. This will help the investigators to understand if these farming practices impact muscle protein synthesis and overall health. Specific aim 1: Describe the post-prandial nutrient and hormonal profile in serum in the 3 hours following consumption of 100 grams (\~32g of protein) of boneless-skinless conventional vs. regenerative chicken breast meat. Specific aim 2: Compare the ability of boneless-skinless chicken breasts grown with these two farming practices to activate mTORC1-specific and whole muscle protein synthesis in an in vitro model of muscle.

The Food Effect on Pharmacokinetics Study of QLC1101 in Healthy Subjects

This randomized, open-label, three-period, three-treatment crossover Phase I clinical trial is designed to evaluate the pharmacokinetic profile of QLC1101 capsules administered as a single oral dose under fasting conditions, following a high-fat meal, and following a low-fat meal in healthy adult subjects. The study will further characterize the food effect on QLC1101 pharmacokinetics. A total of 18 eligible subjects will be enrolled and randomized into three treatment sequences (A, B, C) using a balanced crossover design, with 6 subjects per sequence. The study comprises three treatment periods separated by appropriate washout intervals. In each period, subjects will receive a single dose of QLC1101 under one of three distinct dietary conditions according to their assigned sequence. Following completion of the first treatment period and a washout phase, subjects will crossover to the next dietary condition in the subsequent period, with this process repeating through all three study periods.
