Filter by:The project examines electroencephalography, MRI, and behavioral measures indexing flexibility (critical state dynamics) in the brain when healthy young adults do demanding cognitive tasks, and in response to transcranial magnetic stimulation.
The primary purpose of this study is to demonstrate the equivalence of budesonide, glycopyrronium, formoterol (BGF) metered dose inhaler (MDI) hydrofluoroolefin (HFO) with a spacer to BGF MDI hydrofluoroalkane (HFA) with a spacer. The secondary objective is to characterize BGF MDI HFO with and without a spacer.
Clinical simulation has recently acquired great importance in the health sciences. It is a pedagogical methodology that is increasingly used in health science degrees, since it is very useful for the acquisition of both technical and non-technical skills (leadership, teamwork and effective communication, among others). However, if the investigators focus on physical therapy, the use of clinical simulation is a novel field and therefore requires a great deal of research. Researchers in this field do not yet have the consistency and experience as in other health branches such as medicine or nursing, where the participants have been using high-fidelity simulators for years for the learning of all their students. Clinical simulation allows students to achieve these competencies without the need to practice on real patients. For all these reasons, and because of the situation of need generated in recent years, in which internships in hospitals and clinical centers were completely suppressed, the need for our research is justified.
The goal of this study is to evaluate the role of transcription factor EB (TFEB) in adipose (fat) tissue macrophages (ATM) in regulating adipose tissue and systemic metabolic function in obesity. The investigators will assess the differences in ATM lipid metabolism in people with metabolically abnormal obesity and lean individuals. Both groups will have: - screening visit - imaging (body composition testing - dual-energy x-ray absorptiometry (DEXA) scans, magnetic resonance imaging [MRI] and magnetic resonance spectroscopy [MRS] scans) - Overnight visit with intravenous infusion (IV), muscle, and fat tissue biopsies Participants with obesity will complete meetings with study team members for a weight loss intervention to achieve a 10% body weight loss.
The goal of this observational study is to compare the developmental trajectories of prosocial behaviors and functional network connections in infants and toddlers at high and low risk of autism spectrum disorder (ASD). The main questions it aims to answer are what the differences in prosocial behaviors and related brain network connections between infants/toddlers at high and low risk of ASD are. Participants will receive developmental and social communicational assessments (Griffiths Mental Developmental Scales, Peabody Developmental Motor Scales, The Communication and Symbolic Behavior Scales Developmental Profile Infant-Toddler Checklist), resting-state EEG and MRI in a natural sleeping state.
The aim of the study is to determine the reference values of the Figure 8 Walking Test in healthy adults.
Randomized, double-blind, placebo-controlled study of RSS0393 ointment in healthy and psoriatic subjects
The study aims to optimize and validate protocols for acquiring neurophysiological data, specifically resting state functional connectivity, using advanced research techniques (hdEEG and MEG) and a user-friendly device (MUSE). Previous studies have extensively explored functional connectivity repeatability in resting conditions using functional MRI, yet few have focused on hdEEG and MEG data. Additionally, the impact of subjects' eye conditions (open or closed) during resting state recordings on network identification remains debated. The investigation involves assessing the effect of eye conditions on brain network identification and determining the most stable and repeatable measures of functional connectivity over time. This analysis is crucial for discerning whether observed changes in patients' functional connections are intrinsic to the methodology or indicative of genuine physiological alterations. The study aims to optimize protocols for rehabilitation by evaluating changes in functional connectivity metrics during and between experimental sessions. Furthermore, it seeks to identify the conditions (eyes closed or open) that yield more reliable and repeatable functional measurements. Following the optimization of advanced techniques, the study explores the feasibility of utilizing the MUSE EEG system in clinical settings. MUSE, known for its portability and user-friendliness, has demonstrated quality in experimental psychology and clinical research. The objective is to establish relevant functional correspondences between measurements obtained through research techniques (hdEEG and MEG) and those acquired with MUSE. The primary goal is to establish a protocol highlighting subjects' responses to acoustic stimuli or a reproducible pattern of resting state activity. The secondary objectives include investigating temporal and spatial characteristics of neurophysiological signals in healthy subjects over time and defining prognostic biomarkers for monitoring patients undergoing rehabilitation. This comprehensive approach aims to enhance the understanding of resting state functional connectivity and its applications in clinical settings. Therefore, to meet these goals, the present study will consist of multiple recordings of brain activity: by high-density electroencephalography (hdEEG), magnetoencephalography (MEG), and low-density EEG with a MUSE handheld device, during five experimental blocks on healthy subjects.
This research study aims assess whether the Difference Frequency Generation (DFG) laser could be a better alternative to the CO2 laser in terms of reduced side effects and patient downtime.
The goal of this clinical trial is to evaluate the feasibility and effectiveness of transcutaneous auricular vagus nerve stimulation (taVNS) in enhancing sensorimotor learning and adaptation. This study will focus on healthy individuals performing a robotic sensorimotor task. Main Questions it Aims to Answer: How does taVNS, with different timing protocols, affect the feasibility and effectiveness of performing a robotic sensorimotor task? What is the impact of taVNS on sensorimotor learning and adaptation? Participants Will: Be pseudo-randomly assigned to one of five experimental groups with different taVNS stimulation timings. Perform a sensorimotor task multiple times across sessions, spanning a maximum of two weeks or until achieving 70% accuracy in two successive sessions. Have kinematic data collected by a robot during the task. Have physiological data measured using external sensors. Fill out questionnaires about the feasibility of taVNS and other subjective measures after each session. Comparison Group: Researchers will compare the four experimental groups to each other to see if different taVNS stimulation timings affect sensorimotor learning outcomes, as well as to a control group that will receive no stimulation.
