Filter by:This is a mechanistic, randomized, investigator-blinded, placebo-controlled, single-center, crossover study designed to evaluate the effects of premeal administration of whey protein microgels compared to placebo on postprandial glycemia in patients with type 2 diabetes.
This experiment evaluates the effect of Barley Green in patients with hyperuricemia ， and explores the effect of Barley Green on metabolic indexes such as uric acid, blood lipids, blood glucose, free fatty acids。130 adult participants , age 18 to 65 years, will be randomized into one of the two arms. Arm A (control group) will receive dietary guidance. Arm B will receive dietary guidance and Barley Green.
The purpose of this study is to determine whether the freshwater clam extract and its combination is effective on the improvement of glucose and lipid metabolism, also evaluate its ability to postpone prediabetes patients to become diabetes.
Whereas beetroot juice (BJ) supplementation is shown to increase physical performance in endurance activities, its benefits in team sports has been barely studied. In this randomized placebo-controlled study, we investigated the effects of BJ acute supplementation in improving neuromuscular performance and physical match activity in basketball.
The purpose of this study is to determine if probiotic lozenges taken once a day before bedtime for twelve weeks can decrease the numbers of Streptococcus mutans
Increasing evidence favours exercise therapy as an efficient tool to counteract inactivity related secondary symptoms in MS. Furthermore, exercise therapy may affect MS-associated muscle contractile and energy supply dysfunctions. So far, low to moderate intensity exercise rehabilitation has shown to induce small but consistent improvements in several functional parameters. High intensity exercise training in MS seems to further improve this. However, although results are promising, impairments in both muscle contraction and energy supply probably attenuate therapy outcome. In keeping with the above described physiological role of skeletal muscle carnosine and because muscle carnosine content may be lower in MS, the primary aim of the present project is to investigate whether carnosine loading improves exercise therapy outcome (exercise capacity, body composition) and performance in MS. If the latter hypothesis can be confirmed, muscle carnosine loading could be a novel intervention to improve exercise capacity and muscle function in this population.
Purpose: A growing body of epidemiological data suggests an increased risk of cardiovascular events associated with air pollution. One of the common air pollutants, ozone, has been shown to induce oxidative stress and inflammation in the cardiovascular and respiratory systems. This proposed study is to examine the efficacy of fish oil and olive oil in modulating cardiovascular and pulmonary functions after ozone exposure. The objective is to understand the mechanistic basis for the health effects of ozone relative to those air pollutants. Treatment groups will include forty healthy young adults who will be given dietary supplementation of fish oil or olive oil. A control group will consist of 20 healthy volunteers who will receive no supplements. After 4 weeks, subjects will be exposed to clean air for 2 hours on the first day, then ozone for 2 hours on the second day. Cardiac rhythm, pulmonary function, vascular responses, endothelial function, and markers of coagulation and airway inflammation pre- and post- ozone exposure will be measured. This study is designed to build on the previous nutritional supplement interventional studies (UNC IRB # 07-0190 and UNC IRB # 11-1807), in order to understand the mechanism of action of particulate pollutants in comparison to that of ozone, a known oxidant air contaminant. Participants: A total of sixty healthy 18-35 year-old male and female subjects will be involved in the study. Procedures (methods): Forty healthy young adults will receive dietary supplementation consisting of fish oil or olive oil for 4 weeks. The control group includes 20 healthy volunteers who will receive no supplements in the study. After 4 weeks of supplementation or control regiment, each subject will be exposed to clean air for 2 hours on the first day, then ozone for 2 hours on the second day.
The purpose of this study is to investigate whether vitamin D3 (70 micrograms) is better than placebo in preventing depression symptoms among employees in health care
