Filter by:Cranberry is a fruit native to North America that is widely grown in Quebec and has been shown to have the highest antioxidant capacity among the most commonly eaten fruits. Consequently, consuming cranberries prior to exercising may help to improve exercise endurance by preventing accumulation of reactive oxygen species. For aerobic endurance, in order to maintain a certain pace for a long duration, runners need to effectively neutralize reactive oxygen species. Although it is not the only component involved in running, offsetting reactive oxygen species should improve running performance. To test this, we plan to investigate the effects, both acute and chronic, of a cranberry extract on the oxygen consumption in 18-35 year old males and females. The present research project will contribute to expand our knowledge of how cranberry extract can exert a positive effect, and thus improve aerobic performance or even every day life. This project can benefit a wide range of the population, from sedentary individuals and older adults to elite athletes by providing an all-natural supplement alternative.
This study will include 20 healthy subjects with intact skin on their lower legs that meet inclusion criteria. Participants will serve as their own control, by heating one leg and not the other. The radiofrequency device consists of a 4 by 6 inch heating pad connected to a temperature controller. Subjects will receive weekly treatments for 4 weeks, and will be re-evaluated 4 weeks after the last treatment to assess any tissue changes that continue after the treatments have concluded.
This project will describe the mechanisms of action and the relative contributions of GIP and GLP-2 to changes in gastrointestinal blood flow induced by oral glucose, exogenous GIP and GLP-2 infusions, and endogenous GIP and GLP-2 with the use of two novel receptor antagonists GIP(3-30)NH2 and GLP-2(3-33) in healthy individuals.
The purpose of this pilot study is to investigate whether two major vasopressors (norepinephrine vs. phenylephrine) used for treatment of hypotension during breast reconstruction with free flap transfer surgery have different effects on blood flow of the flap vessel measured by transit time flowmetry. Since there are few prior studies that compared the effects of these two vasopressors on the blood flow of the flap, this study will be conducted in the form of a pilot study in order to establish the evidence for the future randomized controlled trial.
The objective of this project is to determine the importance of peripheral vascular function on gait performance in older adults.
Diabetes and high blood pressure are risk factors for developing heart disease. An increase in the number of diabetes patients is expected. This increases the number of patients with heart disease, and since the vast majority with diabetes die from heart disease, it is extremely important to investigate how these diseases can be prevented and treated. Studies in animals have shown that intestinal hormone glucagon-like peptide-1 (GLP-1) can expand blood vessels, thus lowering blood pressure, but it is not known whether the effects is found in humans, which we will investigate. Studies have also shown that GLP-1 lowers blood sugar, but it is unclear whether this is solely due to increased insulin production, weight loss associated with GLP-1 intake or GLP-1 has an effect on the muscles which increases the uptake of sugar. We investigate whether GLP-1 enhances the absorption of sugar in the leg. The investigators also examines whether these effects are greater in people with diabetes then in healthy.
This randomized clinical trial investigates the effect of the extracorporeal shockwave therapy (ESWT) on periodontal and endodontical parameters. The ESWT is a scientifically approved non invasive method to influence bone turnover and tissue regeneration. The hypotheses of this trial are that ESWT increases the periodontal stability of orthodontically aligned teeth as well as increase the blood flow. Increasing the periodontal stability would reduce the retention phase, relapse risk and accelerate the rehabilitation of the surrounding tissues.
