Making Meals With Pulses

The goal for this study is to determine how Americans use beans, peas, and lentils (also called pulses) as part of a meal. The researchers will investigate food choices when getting a meal or dish ready that is made of more than two foods. Secondly, they will determine how study participants feel about eating pulses.

Physiological and Biochemical Responses to Blood Flow Restriction Training

This study is designed to examine the short-term and long-term effects of blood flow restriction exercise training on physiological and biochemical markers in individuals who are new to strength training and in experienced athletes training at different load levels. This exercise method involves placing a special inflatable cuff around the upper part of the thigh. The cuff partially limits blood flow to the area, which helps the muscles work more effectively during exercise. The cuff will be applied only to the individual's dominant leg (the leg you use more often in daily activities), but all exercises will be performed using both legs. The exercise program will last for a total of six weeks and will be carried out twice per week. The pressure applied by the cuff will be individually adjusted based on each participant's physical characteristics to ensure safety and comfort. The study will include a total of 30 healthy participants aged between 18 and 40 years. Participants will be divided into two groups: individuals who have recently started strength training and experienced athletes with different levels of training experience.

FIRE-Diet: Food as an Intervention to Reduce the Effects of Woodsmoke Exposure on Respiratory Health

Research suggests that consuming more fatty fish, fruits, and vegetables could potentially shield the lungs from the negative impacts of air pollution. The research team will look at whether a dietary intervention aimed at increasing intake of these foods can protect the lungs from woodsmoke as the air pollutant and look into how this works.

Effects of BLa80 and LRa05 on the Gut Microbiota Metabolite Profile of Healthy Individuals

Gut microbiota play a key role in polyphenol metabolism, participating in the breakdown of dietary components and producing various small molecule metabolites that affect human health. However, little is currently known about how gut microbes metabolize dietary compounds and produce bioactive metabolites. This study aims to use metabolomics to precisely identify food-derived metabolites in the blood to investigate whether probiotics (BLa80, LRa05) can enhance the breakdown of dietary components and improve their absorption and utilization in the human body.

Effects of Peripheral Magnetic Stimulation on Cortical Excitability in Healthy Individuals

This study investigates the immediate effects of different parameters (frequency, intensity, and pulse number) of peripheral magnetic stimulation (rPMS) on cortical excitability in healthy individuals. Using a randomized, double-blind crossover design, the research aims to identify optimal stimulation protocols for modulating neural activity. Outcomes include measurements of motor-evoked potentials (MEPs), intracortical inhibition (ICI), and facilitation (ICF). Findings may enhance non-invasive therapeutic strategies for neurological disorders.

Exercise Capacity, Muscle Oxygenation, and Physical Activity Between Patients With Interstitial Lung Disease

Interstitial lung diseases (ILD) are a group of chronic respiratory diseases that cause significant mortality and morbidity worldwide. Although there are studies in the literature comparing different lung disease groups with healthy individuals, it has been determined that there is no study comparing the exercise capacity, muscle oxygenation, physical activity level, respiratory functions, respiratory and peripheral muscle strength, inspiratory muscle endurance, quality of life and sleep quality of individuals diagnosed with ILD with healthy individuals.

Health Effects of Wood Smoke and Traffic-Related Air Pollution Exposures: a Necessary Comparison

Accumulating evidence demonstrates that breathing air pollutants leads to devastating increases in sickness and death worldwide over time. However, there is little data comparing the effects of different types of air pollution on health. In Canada, traffic-related air pollution and wood smoke (wildfires and wood burning for heating) are very common air pollutants. This study aims to safely complete a controlled human exposure study to test how these air pollution types acutely affect health.

Autonomic Nervous System and Meridian Energy in Patients With Schizophrenia

This study aims to explore the differences in autonomic nervous function and meridian energy between schizophrenia patients and healthy individuals. By understanding the meridian and organ conditions of individuals, the study aims to align with the traditional Chinese medicine (TCM) concept of "treating disease before it arises" and provide comprehensive care to patients, thereby improving the quality of care.
