Filter by:The purpose of this research is to measure how toddlers burn fat after drinking milk that has some fat molecules that can be tracked based on how heavy they are.
Cystic fibrosis (CF) is the most common lethal inherited disease in Caucasian populations. To improve survival, it is essential to understand the development, progression and treatment of CF lung disease throughout early childhood. Therefore the overall objective is to prospectively assess the clinical utility of novel and non-invasive measuring methods, namely Multiple Breath Washout and functional lung MRI in the longitudinal clinical surveillance of patients with CF and compare the results to those of healthy controls.
To determine if senolytic drugs reduce senescent cell burden and reduce bone resorption markers/increase bone formation markers in elderly women.
Platelet activation has been associated with bad events like heart attack and stroke. There are a variety of platelet activators that regulate how active a platelet is. We are interested in Protease-activated receptors (PAR)-1. We are currently studying PAR-1 activation in persons with severe peripheral artery disease. We seek, through this project, to understand PAR-1 activation in persons without peripheral artery disease. As many patients with peripheral artery disease have diabetes, we will also evaluate PAR-1 activation in persons with type 2 diabetes. In addition we will assess the impact of the glucagon-like peptide (GLP)-1 signaling pathway on platelet activation. Levels of platelet activation will be determined using platelet aggregation experiments and assessment of platelet-monocyte aggregates in peripheral blood.
Preventive and rehabilitation programs include plyometric exercises to promote agility, power, and muscle activation pattern during jumping. These exercises also are known to cause a high mechanical load that increases the risk of a musculoskeletal injury. The knowledge regarding the musculoskeletal damage result from this configuration of exercise can help to elaborate safer and effective training and rehabilitation programs. In this study, the investigators will conduct a clinical trial to determine the acute effect of plyometric exercises on damage caused on different portions of quadriceps and biceps femoral's muscles and tendons of quadriceps, and biceps femoral, and its effects on mechanical properties.
The project represents a well powered study of the human response to altitude exposure combined with rHuEPO treatment. A total of 20 male and 20 female non-competing athletes will participate. The participants will be exposed to a period of hypobaric hypoxia at 2.320 m for four weeks and a sea-level intervention period of four weeks. The participants will be blinded and randomly allocated to intra venous injection with 20 IU per kg body weight of recombinant human erythropoietin or placebo every second day for the initial three weeks of each intervention. Included subjects will be runners due to the good possibility of recruitment and conduction of training at altitude. Samples are collected weekly for four weeks prior to each intervention period, during the four week intervention and four weeks after. This approach yields a highly valuable biobank for identification of markers sensitive to initiation of rHuEPO injections as well as termination of injections.
The investigators piloted the characterization of the human chronobiome. Now, this line of research is extended to explore physiological chronobiome modulated by sex, age and under evoked conditions.
A remote study to find out if a mobile phone application (HealthMode Stool) can serve as a useful tool to track and characterize daily bowel movements. The application provides participants with a single place to record their bowel movements either as a part of their general health self-monitoring, or because they may be dealing with a bowel movement condition. The minimal study duration is 1 month, and participants can continue using the application up to 2 years.
This study will evaluate the availability of phytonutrients in two blueberry varieties, chosen for their phytonutrient levels. This will be compared to phytonutrient-matched processed protein bar and a macronutrient-matched control meal, in healthy human volunteers. Blueberry phytonutrients will be analyzed in blood and urine over a four-day period, 48h prior to consumption and 48h after. The participants will consume each of the four meals over a 3-month period (4-way crossover design, 4 blocks of 4-day periods). The main objective of this study is to compare the proportions of blueberry phytonutrients recovered in the blood and urine after ingestion of the four treatments. We hypothesize that phytonutrient content will be predictive of human bioavailability and that a berry-enriched processed product will have similar phytonutrient bioavailability to unprocessed berries. The results of this study may establish if the nutritional value of a berry can be predicted or enhanced to provide elevated nutritional quality, with the ultimate goal of maximizing the health benefits of fruit consumption. As it is challenging for many to increase their fruit and vegetable intake to government recommended levels (5+ servings per day), the present proof-of-concept study explores a reasonable approach to help consumers achieve optimal health associated with high fruit and vegetable intakes, within the context of current consumption patterns, through enhancement of the nutritional density and bioavailability of common fruits and consumer products.
A Phase 1, randomized, double-blind, placebo-controlled dose escalation trial of four dose cohorts of 10 subjects (A: 10mg, B: 25mg, C: 50mg, D: 100mg).
