In this research study, the investigators will use a novel approach to measure what people eat. The goal is to find out whether stable isotopes that can be measured in blood, hair, and fingernails are better at measuring what people eat than the surveys that are currently used. T…

T1rho imaging is a new MRI technique that has strong potential in neuroimaging. This technique does not require exogenous contrast agents and has high spatial resolution. In this study we aim to characterise the normal appearance of T1rho in the brain parenchyma in healthy parti…

To evaluate the physiologic effects of an electromagnetic resonator(EMF) on autonomic nervous system tone modulation through measurement of heart rate variability(HRV). Null Hypothesis: An EMF Resonator will not change autonomic nervous system tone and no demonstrable difference…

The purpose of this study is to more rigorously evaluate the response to a single bolus of magnesium sulfate in a population of patients with moderate to severe bronchiolitis. The primary outcome will be to evaluate the effect of this therapy on clinical respiratory status. Secon…

This study aims to clarify, in patients with more or less abundant pericardial effusion in the acute phase of a myocardial infarction, the correlation between the existence of this effusion during the acute phase with clinical parameters, biological, angiographic, therapeutic and…

There are limited data regarding the burden of hyperkalaemia in patients attending emergency departments (ED) or who are hospitalised (excluding those already receiving dialysis). Renin-angiotensin-aldosterone system inhibitors (RAASi) are of prognostic benefit in patients with h…

Antiphospholipid syndrome (APS) is defined by thrombosis or obstetric complication (≥ 3 spontaneous miscarriages or fetal death or prematurity \<34 weeks gestation-related amenorrhea (SA)) associated with antiphospholipid antibodies. The rate of term pregnancies has been improved…

The purpose of this research is to use 18 F Fluorodopa positron emission tomography (FDOPA PET) to measure dopamine function, and utilize magnetic resonance imaging (MRI) to measure inflammatory and oxidative stress markers in persons with Parkinson's disease. The overall goal o…

The proposed research is a feasibility pilot trial designed to optimize the remote collection dried blood spots (DBS) from a finger stick and the analysis of fatty acid from the DBS and to optimize the analysis of mitochondria activity (or energy metabolism) from peripheral blood…

Healthy controls (HC) will be studied once to provide data needed to validate the virtual neuro-navigation system. All subjects will undergo a single MRI session and will then participate in an on-line neuro-navigation session in which various TMS coil positions will be recorded.…

The primary aim of the study is to investigate whether a novel mobile App-based behavioral intervention in pregnant women can: (1) prevent and/or decrease the incidence of perinatal mood disorders (2) decrease the severity and/or duration of perinatal mood disorders in affected p…

To evaluate the safety and tolerability of multiple intravenous infusions of Ginkgolide B Injection in healthy Chinese participants, as well as to assess the pharmacokinetic (PK) characteristics following single and multiple doses.

For leadership positions with only a handful of staff under their direct chain of command, this may not be all-consuming and detrimental to work-life balance. But for NMs with upwards of 100 direct reports, this can make for a never-ending stream of contact points. This study wil…

This will be a prospective case-control study of 40 patients undergoing 1-2 level ALIF procedures at Methodist Dallas Medical Center (MDMC). Patient records will be reviewed to identify details including demographics, comorbidities, procedure details, and the primary and secondar…

The purpose of this study is to characterize the pharmacokinetics of intravenous and oral omadacycline in patients with cystic fibrosis.

The objective of the research is to study the expression of the ACE 2 receptor and the TMPRSS2 serine protease in the tonsils and adenoids of children and adults.

This study is single center, subject will receive a wireless TENS device. All subjects will be allowed to keep the commercially-available device for use after the study. The primary goal is to test the feasibility of the study design and secondary is to test the preliminary effic…

Cesarean delivery (CD) is an obstetric surgery for fetal delivery that involves both an abdominal incision (laparotomy) and a uterine incision (hysterotomy). It is presently the most prevalent surgery in the United States, with over 1 million women giving birth by cesarean sectio…

The purpose of this research is to try to better understand how much information relating to cancer screening and diagnoses that people can recall on their own and to better understand how to help people get better information. In this study, investigators will see if giving time…

Wrestling is a weight-classified sport in which athletes frequently apply rapid weight loss (RWL) strategies prior to competition. While the performance-related consequences of RWL have been widely investigated, its combined effects with exercise on hematological parameters and i…
