Optimizing Neuromodulation through Individualized Stimulation Frequencies
Transcranial magnetic stimulation (TMS) is a non-invasive mechanism for stimulating brain regions in humans. TMS can potentiate or inhibit activity in various brain regions, and it allows researchers to exert causal control to explore and define network connectivity among brain regions. Using real-time brain readouts combined with interleaved TMS/fMRI, we …
Participate in a Birth Control Patch Research Study!
The Women's Health Clinical Research Center at University of Pennsylvania is currently recruiting healthy women who have regular periods and do not wish to become pregnant for at least 12 months for a research study of an investigational birth control patch. The study patch that will be used in this …
Noninvasive Quantification of Renal Oxygen Utilization in Early Kidney Disease
PURPOSE/DESCRIPTION: The purpose of this study is to measure how much oxygen is used by the kidneys. The kidneys play an important role in removing waste products from the body. In people with chronic kidney disease and diabetes, the kidneys do not function normally and have changes in oxygen consumption. …
Determination of B-cell responsiveness to the incretin hormones GLP-1 and GIP in Cystic Fibrosis (PRIME)
The mechanisms underlying cystic fibrosis related diabetes (CFRD) pathophysiology must be better defined if care for people with CFRD is to be optimized or if development of CFRD is to be interrupted. Detailed studies of insulin secretion in CF are required to achieve this goal since 1) subtle insulin secretion …
Aging Chronobiome Study (Acronym-1)
We invite you to participate in a research study where we explore how young and old people differ in their behavioral and biological rhythms. The main criteria to qualify as a research subject are: 1.) you are apparent healthy, 2.) you own a smartphone and 3.) you are either between …
Network Control TMS fMRI
The University of Pennsylvania seeks young adults ages 18-28 for a research study. The purpose of this study is to use different types of MRI scans to find individualized TMS (transcranial magnetic stimulation) targets and compare how the brain responds. We are also interested in using TMS during a working …
Effects of Nutritional Ketosis on Alcohol Metabolism
The research study is being conducted to better understand the effects of ketosis on brain functioning and the acute effects of alcohol. Participants will be asked to undergo ~4 weeks of ketogenic diet intervention. The study involves three lab visits: Lab 1 before starting the diet, Lab 2 after about …
PRELIMINARY STUDY OF OPTICAL BIOMARKERS FOR NEURODEGENERATION IN CHRONIC CEREBROVASCULAR DISEASE
This research study will test whether a new optical device can reliably measure markers of blood flow and blood vessel function in the brain. We will be recruiting 60 subjects in total: 30 healthy, 15 with known narrowing of the carotid artery, and 15 small vessel stroke. All subjects will …
Analyses of Complement and Other Candidate Fluid Biomarkers in Schizophrenia Spectrum Disorders
The purpose of this research study is to identify biological markers for schizophrenia and related mental illnesses. We are gathering medical information, behavioral assessments, cells and genetic material (DNA), as well as blood and cerebrospinal fluid (CSF), and brain images from persons who appear to have a psychiatric disorder and …
Changes in the lymphatic system on MR Lymphangiography (MRL) in patients with congestive heart failure (CHF).
Observational study of adults with congestive heart failure and normal healthy participants using Magnetic Resonance Imaging (MRI) to compare changes in the lymphatic system (thin tubes and lymph nodes that run throughout the body).
