Healthy Paid Clinical Trials in New York

The Ezra Faster Scan study uses non-invasive magnetic resonance imaging (MRI) technology that can "visually" detect early and late-stage cancer, and other pathologies. MRIs use a magnetic field and radio waves to create a 3-dimensional (3D) image of an individual's body without using ionizing radiation. The purpose of this research is to decrease the amount of time required by an individual to complete an early cancer screening comprehensive magnetic resonance imaging (MRI) scan, such as the Ezra Full Body MRI imaging scan. If the time required to conduct a comprehensive scan is reduced, the cost of the scan may also decrease. By decreasing consumer costs and time, more individuals may be able to afford MRI-based early cancer screening technology. Participants in this study will undergo a minimum 30-minute MRI session. These sessions will be used to evaluate new MRI "instructions" that allow for a faster MRI scan time. The images will also be used to develop mathematical models or machine learning tools that allow images to be enhanced. By enhancing images using machine learning, they may be restored to a quality typically observed in MRI sessions with longer scan (acquisition) times.

The purpose of this observational research study is to better understand immune responses to vaccines against viruses (influenza or SARS-CoV2). The goal is to determine any differences in immune responses to vaccines in uninjured people and in people living with spinal cord injuries, who are typically at increased risk of infections.

Executive control processes involve initiate, coordinate, synchronize, and regulate elemental cognitive functions for the conduct of goal-directed behavior. The proposed research investigates whether exposure to a web-based training protocol designed to enhance executive control processes will improve cognitive performance in cognitively healthy older adults.

In this study, we investigate the impact of insulin resistance on the acceleration of brain aging, and test whether increased neuron insulin resistance can be counteracted by utilization of alternate metabolic pathways (e.g., ketones rather than glucose). This study has three Arms, which together provide synergistic data. For all three Arms, subjects are tested in a within-subjects design that consists of 2-3 testing sessions, 1-14 days apart, and counter-balanced for order. During each session we measure the impact of fuel (glucose in one session, ketones in the other) on brain metabolism and associated functioning. For Arms 1-2, our primary experimental measure is functional magnetic resonance imaging (fMRI), which we will use to trace the self-organization of functional networks following changes in energy supply and demand. Arm 1 tests the impact of endogenous ketones produced by switching to a low carbohydrate diet, while Arm 2 tests the impact of exogenous ketones consumed as a nutritional supplement. For Arm 3, we use simultaneous magnetic resonance spectroscopy/positron-emission tomography (MR/PET) to quantify the impact of exogenous ketones on production of glutamate and GABA, key neurotransmitters. Subjects will be given the option to participate in more than one of the Arms, but doing so is not expected nor required. Prior to scans, subjects will receive a clinician-administered History and Physical (H&P), which includes vital signs, an oral glucose tolerance test (OGTT), and the comprehensive metabolic blood panel. These will be used to assess diabetes, kidney disease, and electrolytes. If subjects pass screening, they will be provided the option to participate in one or more Arms, which include neuroimaging. To provide a quantitative measure of time-varying metabolic activity throughout the scan, based upon quantitative models of glucose and ketone regulation, as well as to be able to implement safety stopping rules (see below), we will obtain pin-prick blood samples three times: prior to the scan, following consumption of the glucose or ketone drink, and following completion of the scan. To assess effects of increased metabolic demand, we measure brain response to cognitive load, transitioning from resting-state to spatial reasoning through a Tetris task. To assess effects of increased metabolic supply, we measure brain response to glucose or ketone bolus. Read Less

The main goal of this research is to determine the role of several brain regions in memory processes and cognitive functions. Participants will be remotely supervised via video chat while self-administering tDCS, a form of non-invasive brain stimulation. Before participating in the experiment, participants will be properly trained on use of the remote tDCS device and screened for eligibility. While using the tDCS device, participants will be engaging in tasks that assess different aspects of memory and executive functioning. By using remotely supervised tDCS while participants are completing these cognitive tasks, we will be able to make causal claims about the role of the targeted brain regions in different cognitive processes.
