Filter by:The objectives of this study are 1) to determine if consumption of mixed nuts influences food intake and choice, and 2) to determine how personality traits affect food choice, including mood, stress, tendency to seek approval, tendency toward food cravings, and approach to food intake control.
In this study, the investigators propose to assess the validity in measuring physical activity (PA) of a new PA monitor system the MOTIONPODTM, that coupled a hip-worn multi-sensor device (associating a tri-axial accelerometer, a magnetometer and a gyroscope) with an automatic activity/posture recognition algorithm and an activity-specific multilinear prediction model. The MOTIONPODTM performances in predicting mean daily PA energy expenditure (PAEE) will be calculated against the reference PAEE gold standard measure, using the doubly labeled water method (DLW). The MOTIONPODTM performances in predicting PAEE and PA patterns will be compared to those of two existing activity or movement monitors: the triaxial accelerometer ActigraphGT3X+TM and a device combining cardiofrequencemetry with accelerometry, the ActiheartTM. This latter has demonstrated fair performances but at the cost of a calibration of the heart-rate/EE relationship that limits its use in large population samples. Briefly, this open study will include 120 subjects, aged 18 to 75 years of both gender and with broad range of body mass index and physical activity level. The subjects will carry a MOTIONPODTM, an ActigraphGT3X+TM, an ActiheartTM and a GPS for a total of 14 days in everyday life conditions and complete a physical activity diary. In half of the subjects, PA will be evaluated on a period of 14 days, with standard PAEE measured by DLW. The other 60 subjects will be studied twice, one month apart, to test the reproducibility of the measures.
This is a first-in-human, phase 1, single centre, placebo-controlled, double-blind, single ascending dose study of LEVI-04 in heathy volunteers and osteoarthritis patients (with pain attributed to osteoarthritis of the knee)
TRACERx Renal: This is a translational study, which, aims to develop prognostic and predictive biomarkers for patients with renal cell carcinoma (RCC). CAPTURE Sub-study: Covid-19 antiviral response in a pan-tumour immune monitoring study
Background: Little is known about the time it takes for nerve signals to go from one area of the brain to another. Using advanced methods for brain research, researchers want to look at the time it takes to send messages between different brain areas. They also want to develop new tests. Objectives: To develop tests to measure the sizes of nerve fibers in the peripheral nerve system and in the brain. Also to find out the different speeds that information travels in nerve fibers. Eligibility: Healthy, right-handed people ages 18-70 Design: Participants will be screened with medical history and a physical exam. Participants will have up to 7 visits depending on the tests they choose. Visits last about 2-4 hours and may involve the following tests: - Physical exam - Urine tests - Magnetic resonance imaging (MRI). Participants lie on a table that slides into a scanner. They will be in the scanner for up to 1 hour. For some scans, sensors are placed on the skin. They will get earplugs for loud noises. - Small, sticky pads on the skin will electrically stimulate nerves in the forearm. - Transcranial magnetic stimulation (TMS). A wire coil will be held to the scalp. A brief electrical current passes through the coil to affect brain activity. - Electroencephalography. TMS will be given to the brain. Small electrodes on the scalp measure brain activity. Participants may do small tasks. - Electrodes on the scalp will send an electrical current to the brain. - A cone with magnetic detectors will be lowered onto the head to record brain activity. Participants will perform various tasks.
This project pursues the validation of an innovative strategy to boost language learning, based on the benefits derived from sensorimotor training. The common belief of a rigid brain structure in adult life had to be reconsidered during the last decade. After training, local increase in cerebral cortex volume and thickness, the part of the brain containing neuronal cells and synapses, has been documented. Research has established that brain structures active during training expand while learning and return to baseline afterwards. The transient structural increase is thought to reflect "work in progress" within areas involved in learning, meant to integrate new skills in existing neural circuitries, via strengthening and/or selection of local neuronal connections. My main hypothesis is that other functions, as long as they rely on the activity of the same brain territories, can take advantage of this "work in progress". To use an allegory, imagine the restauration of a building (brain area). It can start after the request of improvements from some of the residents (trained function) and then become the occasion for other tenants (other functions) to see realized also their own wish for improvements. In the end everybody will benefit from the restauration, provided that they all live in the same building and everybody has posed their requests during the "work in progress". Out of the allegory, living in the same building means neural overlap of functions in the brain. The case of motor and linguistic systems represents, from this perspective, a unique opportunity. State-of-the-art research 1) proved the existence, and described the temporal evolution of brain plastic changes during sensorimotor learning, and 2) documented neural overlap and functional interactions of motor and linguistic systems. This posits solid bases for a crucial step forward, gravid of important consequences and applications. This project aims to take this step forward by directly testing the innovative hypothesis that brain changes induced by sensorimotor learning induce benefits for linguistic functions relying on the same brain territories.
This study will be a single center, open-label, 2-period, fixed-sequence, Phase 1 drug-drug interaction study in healthy subjects. The primary purpose of this study is to evaluate the effect of itraconazole on the PK of ipatasertib and its primary metabolite (G-037720).
The primary objective of this study is to evaluate the safety and tolerability of single ascending doses of subcutaneous (SC) injections of RO7049665 in healthy volunteers. In addition, pharmacokinetics (PK) of RO7049665, the effects of single doses of RO7049665 on regulatory T-cells as well as the single dose immunogenicity of RO7049665 will be evaluated. This trial plans to evaluate approximately seven single dose-levels of RO7049665 or matching-placebo during dose-escalation in approximately 40 participants.

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of single ascending doses of PF-06852231 after first-time administration to healthy adult subjects. The safety, tolerability, and pharmacokinetics of an active metabolite (PF-06892787) will also be evaluated in this study.
