Type 2 diabetes and obesity are both multifactorial diseases resulting from gene-environment interactions. However, this interaction, as well as the specific effect of each polymorphism, remains poorly understood. We now proposed a prospective cohort study to improve our underst…

This study will explore the growth of dermal neurofibromas (skin tumors) in patients with neurofibromatosis type 1 (NF1). Investigators will try to learn: 1) how fast (or slow) these benign tumors grow in NF1, 2) how often new tumors appear and 3) what genes are involved in the g…

The primary objective of this study is to evaluate the prediction of late toxicity by the radiation induced CD8 T-lymphocyte apoptosis

Acromegaly is a rare disorder characterized by excessive production of growth hormone most often by a pituitary adenoma. A pituitary adenoma is a tumor, almost always benign or non-cancerous, that grows on the pituitary, a small gland located at the base of the brain. Treatment o…

The purpose of this study is to determine if sequence variations in genes involved in the development and function of vulnerable organs increases susceptibility to chronic lung disease (CLD) and other diseases affecting premature infants, such as necrotizing enterocolitis (NEC), …

The purpose of this study is to assess long term (1 year) respiratory sequelae in children surviving an acute respiratory distress syndrome

The goal of this observational study is to learn about the ability of Phenotypic Age Acceleration (PhenoAgeAccel) to predict four key health outcomes in Chinese people with or at risk of major chronic diseases: the risk of developing new chronic diseases, the risk of dying, life …

Antiphospholipid antibody syndrome (APS) is characterized by the presence of antiphospholipid antibodies, which are proteins in the blood that interfere with the body's ability to perform normal blood clotting. Clinical problems associated with antiphospholipid antibodies include…

The main purpose of this study is to investigate whether bosentan (Tracleer®) affects the wall thickness of the pulmonary arteries in patients with idiopathic pulmonary arterial hypertension (iPAH) and PAH related to systemic sclerosis (PAH-SSc). The second purpose is to investi…

This study will use positron emission tomography (PET) to compare how people with Gaucher disease or Gaucher disease carriers with parkinsonism, and their family members, use dopamine in their brains in comparison with healthy normal volunteers and people who have Parkinson disea…

Little is known about the factors that cause biliary atresia nor the factors that influence disease progression. The purpose of this study is to collect the pertinent clinical information, genetic material and body fluid samples to enable investigators to address the following ai…

Epileptic disease is characterised by enhanced brain excitability. Low frequency repetitive transcranial magnetic stimulation (rTMS) can be an effective treatment for refractory frontal epilepsy. Thought, physiological mechanisms of its effectivity are still unknown. It is yet po…

To establish a large, longitudinal collection of high quality samples and data from subjects with MS, selected other demyelinating diseases (Transverse Myelitis (TM), Neuromyelitis Optica (NMO) or Devic's, Acute Disseminated Encephalomyelitis (ADEM), and Optic Neuritis (ON)), and…

The purpose of this study is to determine whether endometriosis and adenomyosis are progressive diseases, in terms of symptoms (pain, abnormal uterine bleeding and infertility), anatomical lesions size, and recurrences. We also aimed to address molecular questions on immune dialo…

To analyze the influencing factors of the success of redo surgery due to anastomotic fistula or anastomotic recurrence after rectal cancer surgery and to evaluate the anal function of patients

It is a biomedical research without direct individual benefit, exploring and comparing the mucosal immune response after oral, nasal and sublingual administration of B-subunit of non-toxic cholera toxin (CTB) in healthy adult volunteers.

Veno arterial extracorporeal membrane oxygenation (VA ECMO) is used, for cardiogenic shock, refractory cardiac arrest and post cardiotomy cardiac failure. Bleeding is frequent complications during VA ECMO and is associated with increased mortality. The aim of our study was to ide…

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare immune system disorder that causes asthma, an excessive number of eosinophils (a type of white blood cell) in the blood, and the inflammation of blood vessels, or vasculitis. In order to properly treat EGPA, it is cri…

Closer examination of granular lipid data in a large population offers numerous opportunities to generate new knowledge, ranging from studies examining concordance between commonly used lipid parameters to phenotypic characterization of rare or extreme disorders of lipid metaboli…

The purpose of this research study is to collect and store brain tumor tissue samples for future research. The samples will become part of the University of Florida Brain Tumor Tissue Bank/Florida Center for Brain Tumor Research. The goal is to find improved treatments and cures …
