Filter by:This study has two main goals : - to investigate the impact of aging on cortical excitability (CE) - to investigate the impact of "state dependency" on CE, using a cognitive task and an emotional one. A Neuronavigation system of transcranial magnetic stimulation is used, and electromyographic response are recorded.
This is a Phase 1, randomized, double-blind, placebo-controlled, single-ascending dose study in healthy volunteers, enrolled at a single site in the United States to investigate the safety, tolerability, and pharmacokinetics of DSTA4637S.
To compare pharmacodynamics among the different concentrations of BCS and NS.
The purpose of this study is to determine the health effects of the 4 weeks daily intake of a drink manufactured from lupine protein hydrolysates in healthy volunteers. For that, blood markers of inflammation, oxidative stress, carbohydrate, lipid, protein and liver metabolism, together with general hematology and blood coagulation will be assessed at baseline time (day 0) and after drink ingestion (day +14 and +28).
Although salivary contents play a major role in the early stage of food digestion process, their role in taste perception of glucose polymers is essentially unknown. It is hypothesized that the differences in salivary contents, more specifically salivary amylase concentration and activity, influence taste perception of glucose polymers and ultimately eating behavior, which is related to risks in various diseases. The current project will investigate the variation in salivary contents across individuals and its role in taste perception of glucose polymers.
The current prospective cross-sectional pilot study is proposed to determine a set of characteristic factors associated with salt sensitivity in young adults by measuring blood pressure, serum aldosterone levels, urine analysis, arterial pulse wave velocity and central arterial pressure in response to short term increases in salt intake.
Determination of fractional iron absorption from dairy product fortified with 2 labelled iron compounds
This phase 1 study will be conducted to examine the degree and duration of brain PDE2A enzyme occupancy /target engagement as a function of TAK-915 plasma concentration in order to guide dosing and schedule for future clinical studies in schizophrenia with TAK-915.
This project aims at assessing two MRI acquisition methods, neurography and tractography, for the visualization of pelvic nerves. The goal is to optimize both methods and to test them on a pool of volunteers to assess if nerves can be delineated, so as to provide an individualized mapping of nerves to surgeons before an intervention and avoid postoperative complications.
If eligible to participate in the research study after completing the physical screening procedures, participants will be asked to return to the Substrate Metabolism Laboratory on another occasion after a short fast (no food or beverages - besides water) for at least 6 hours. After participants arrive, participants will rest quietly for approximately 30 min. The investigators will then collect a blood sample from a vein in participants hand, or forearm. After obtaining a baseline blood sample, participants will exercise at a moderate intensity (on a treadmill or a stationary bike) for one hour. This one hour moderate exercise session will feel like a slow jog during which participants would be able to carry a conversation. In order for the investigators to measure energy expended and the amount of fat participants are burning during exercise, the investigators will periodically ask participants to breathe through a mouthpiece so the investigators can collect participants expired breath. After the exercise session the investigators will collect another blood sample from a vein in participants hand, or forearm.
