The purpose of this study is to examine the long term safety of an experimental gene transfer agent, RetinoStat®, designed to treat neovascular age-related macular degeneration.

This project will be a multi-center, prospective longitudinal cohort for all patients undergoing primary shoulder instability surgery, excluding isolated SLAP repairs. We will be looking for risk factors for recurrent instability, revision surgery, and poor outcomes. Patients wil…

The purpose of this study is to compare immune phenotype, function, and specificity of B lymphocytes from different developmental stages in autoimmune patients to B cells from infectious disease patients and healthy controls.

The purpose of the biobank is to enable future genomic based research on this Head and Neck Cancer patient population. The investigators will try to identify tumor factors that will predict cancer-related outcome in order to improve the outcome prediction after treatment in a pat…

Purpose/Lay Summary: Background: \- Chromosomes are the structures inside of each cell that carry our genetic material (genes). Certain differences in the sex chromosomes are known to cause various diseases, such as infertility, Turner syndrome, or Klinefelter syndrome. However,…

Background: \- Medullary thyroid cancer (MTC) is a rare cancer of the thyroid gland. In children and adults, it is often part of a condition called Multiple Endocrine Neoplasia 2 (MEN2). MEN2 is usually caused by a genetic mutation, and it can cause a number of problems in addit…

Background: \- Innate immunity is the process by which white blood cells and other parts of the immune system sense and respond to potential infections by causing an inflammation. Researchers are interested in studying how the body responds to certain environmental factors, and …

IgG4-related disease is a rare and very recently identified pathology, whose frequency is certainly underestimated. The clinical presentation varies among affected organs, and most often, patients have at least three organ damage. These organs exhibit tissue infiltration mononu…

Background: \- Researchers have been studying patterns of mood and drug use in specific neighborhoods. This study will look at environmental factors that may affect drug use, addiction, and treatment seeking in Baltimore neighborhoods. The results could inform prevention efforts…

The investigators will collect samples of sputum from healthy volunteers and patients with cystic fibrosis for the purpose of: a) purifying airway mucins for plate-based binding studies and; b) assessment of the effects of carbohydrates on the rheologic properties of the sputum. …

The primary objective of the study is to assess the improvement of daily activity in subjects with Stage IV Pulmonary Sarcoidosis one year after the conduct of a pulmonary rehabilitation program. The secondary objectives are the following: * assess the improvement of daily acti…

Several studies in healthy volunteers have suggested that the synchronized functional connectivity in the DMN (Deafult-Mode Network) would sustain the mental content at rest, and when required, a switch in the activity between the DMN and other networks involved in specific congn…

The aim of this retrospective observational study is to investigate the association between genotype and craniofacial phenotype in orthodontic patients affected by Marfan and Loeys-Dietz syndromes. A total of 39 patients aged between 4 and 18 years were enrolled and stratified in…

Background: \- Knowing one s family medical history is a part of staying healthy. Some health risks run in families, and knowing these risks can promote more healthy behavior. Different social and cultural factors may affect how family members share this information. Genetic ris…

Objective: In this study we will develop and apply imaging techniques to perform the first three-dimensional (3-D) measurements of brain biomechanics during mild head movement in healthy human subjects. Biomechanics is the application of mechanics, or the physical principles in a…

Registry database repository for determining clinical outcomes primarily of patients who have received or have been evaluated for radiation treatment in either the definitive or palliative setting for both malignant and benign etiologies. To compare the outcomes with National Ca…

ConeBeam scanner (CBCT) is a widely technique used for dental and maxillofacial imaging. Patients can be set up in a sitting or a laying position in the, Newtom 5G CBCT allowing for an analysis of the limbs distal joints. Our hypothesis is that the cone-beam scanner could detect …

Given the structural essential, catalytic and co-catalytic played by zinc in many sections of protein metabolism, carbohydrate and lipid (zinc is involved in the function of more than 300 metalloenzymes and metalloproteins), one can imagine the impact of a deficiency or even a su…

The purpose of this study is to evaluate and optimize advances in radio frequency (RF) coil magnetic resonance imaging (MRI) technology at Cincinnati Children's Hospital Medical Center (CCHMC).
