Filter by:This is an open-label, non-randomized study to determine the excretion kinetics and mass balance of GDC-0810, and to determine metabolites present in blood, feces, and urine in healthy participants following a single 300-milligram (mg) oral dose of GDC-0810 containing approximately 100 microcuries of [14C] labeled GDC-0810 using conventional absorption, metabolism, and excretion (AME) methodology. The entire duration of the study is up to approximately 8 weeks.
The previous research by one of our members in the research team (H. Miller) suggests a possible influence of oral nutrients intake of certain fat or carbohydrates (glucose, fructose) on executive control. On the other hand, another previous study from our group (L. Van Oudenhove) suggests a subliminal influence of intragastric administration of fatty acids on subjective and neural responses to negative emotion induction. The purpose of this study therefore is to examine the effect of intragastric administration of certain fatty acids and carbohydrates on executive control in healthy volunteers. Therefore one group of healthy volunteers are invited to the study. The participants will be randomly administered one of the three fatty acid emulsions or placebo via a nasogastric tube in each of the visits. After the exposure period, participants will use a computer to perform there different tasks to measure executive control. During each study visit, regular measurements of emotion, physical sensations, as well as blood glucose will be assessed. Furthermore, an electrocardiogram will be continuously recorded for the calculation of vagal function.
This study will obtain whole blood specimens from healthy subjects to be used for research and development and clinical validation of genetic assays.
The primary objective of this study is to assess the relationship between rhinovirus specific T-cell immunity and the human host response to primary rhinovirus challenge and subsequent secondary challenge with either homologous or heterologous rhinovirus serotypes.
The study will be conducted in adult healthy participants and will consist of two phases: Prerandomization and Randomization. The Prerandomization Phase will consist of 2 periods: a Screening Period and a Baseline Period. The Randomization Phase will consist of 2 Periods (each 6 days long) separated by a 1-day long Baseline Period and End of Treatment (EOT) Period. A total of 60 participants will be enrolled into one of three arms. Arms 1 and 3 consist of 2 sequences, and Arm 2 consists of 4 sequences (as this is an incomplete block design with 2 factors [number of capsules and whether water or apple juice is used as vehicle]). Each participant will be randomized into one of 8 sequences.
This study is an open label, parallel group, single ascending dose, exploratory study performed in a single site (Centre Cap, Montpellier, France).
The purpose of this study is to investigate the safety and tolerability of IX-01 after multiple doses, and to determine the PK of IX-01 and activity of CYP3A4.
Hip osteoarthritis is a frequent and invalidating disease. Early detection of cartilage modifications could provide better patient treatment. The T1rho MRI sequence allows the quantification of the cartilage signal that is correlated to modifications of the cartilage matrix, notably of the proteoglycans. The primary objective is to evaluate normal values of hip cartilage in vivo using T1rho MRI in healthy subjects and the reproducibility of the measurements. T1rho and T2 mapping sequences were acquired twice during the same session with 30 minutes interval to see if values were modified after a 30 minutes delay in a supine position. The secondary objective was to assess the correlation between T1rho and T2 values.

Cardiovascular events remain the main cause of death of the industrialized world (Global status report on noncommunicable diseases 2010. Geneva, World Health Organization, 2011). Arterial hypertension, hyperlipoproteinemia, smoking, diabetes and family history represent the main cardiovascular risk factors. Arteriosclerosis leads to coronary heart disease, cerebrovascular insufficiency and peripheral vascular diseases that reflect in myocardial infarction and stroke. The main objective of this experiment is to investigate the differential effect of microgravity on central aortic blood pressure. The main criterion is the central aortic pressure (measured in mmHg). The hypothesis is that microgravity leads to an increased central aortic pressure.
