Adipose-Derived Stromal Vascular Fraction Therapy Improves Age-Related Adrenergic Mediated Microvascular Dysfunction And Increases Revascularization Potential Following Injury., Gabrielle Brown
Electronic Theses and Dissertations
The role of the microcirculation is to balance blood flow and oxygen delivery to meet local metabolic and oxygen demands. With advancing age, the health of the endothelium declines leading to improper augmentation of the microcirculation; decreasing vasoreactivity and angiogenic potential which can further increase the risk of ischemia. The multiple contributing factors that drive the decline in endothelial health with age make traditional pharmacological interventions challenging whereas cell-based therapies can exert multifactorial gains. Adipose-derived stromal vascular fraction (SVF) is an emerging therapeutic for its easily accessible, autologous, anti-inflammatory, and angiogenic properties. It is a heterogenous population comprised of leukocyte …
Perinatal Nicotine With Or Without Early Life Influenza Infection Leads To Lung Dysfunction With Age., Ryan Carroll Mcallister
Perinatal Nicotine With Or Without Early Life Influenza Infection Leads To Lung Dysfunction With Age., Ryan Carroll Mcallister
Electronic Theses and Dissertations
Obstructive Airway Diseases (OADs) affect millions of people worldwide, and are characterized by chronic inflammation and tissue remodeling in the lung. It has been proposed that the development of OAD is greatly influenced (and perhaps pre-determined) by early life events, such as maternal smoking or a viral infection. However, direct evidence of this is limited and the mechanisms involved remain unclear. Our laboratory previously developed a murine model of perinatal nicotine exposure, and reported that nicotine leads to airway remodeling and decreased pulmonary function in the offspring. We discovered these effects were mediated through the α7 nicotinic acetylcholine receptor (nAChR). …
The Role Of Nicotine, A7 Nicotinic Acetylcholine Receptors And Extracellular Matrix Remodeling In Pulmonary Fibrosis., Glenn Ward Vicary
The Role Of Nicotine, A7 Nicotinic Acetylcholine Receptors And Extracellular Matrix Remodeling In Pulmonary Fibrosis., Glenn Ward Vicary
Electronic Theses and Dissertations
The median survival for idiopathic pulmonary fibrosis (IPF) patients from diagnosis is a dismal 3 years. This condition is characterized by pulmonary fibroproliferation and excess production and disordered deposition of extracellular matrix (ECM) proteins resulting in obliteration of the original tissue architecture, loss of lung function and eventual death due to respiratory failure. The main hindrance to the development of effective treatments against pulmonary fibrosis is the late detection of its progression and is often of unknown cause. Tobacco smoke represents the most important environmental factor linked to the development of pulmonary fibrosis, with over 60% of IPF patients current …
Acrolein Is A Critical Mediator Of Alcohol-Induced Liver And Intestinal Injury In Alcoholic Liver Disease., Wei-Yang (Jeremy) Chen
Acrolein Is A Critical Mediator Of Alcohol-Induced Liver And Intestinal Injury In Alcoholic Liver Disease., Wei-Yang (Jeremy) Chen
Electronic Theses and Dissertations
Alcohol consumption can cause alcoholic liver disease (ALD), which remains a major cause of morbidity and mortality in the United States. Chronic alcohol consumption causes a pro-oxidant environment in the liver and increases hepatic lipid peroxidation. Acrolein is the most reactive and toxic aldehyde generated through lipid peroxidation. Acrolein forms protein adducts and triggers endoplasmic reticulum (ER) stress and hepatocyte apoptosis, which are recognized etiologic factors in ALD. Several studies have established the critical role of the gut-liver axis in ALD pathogenesis, wherein alcohol-induced gut barrier dysfunction contributes to liver injury. This study investigates, in vitro and in vivo, the …
