Superoxide And Pulmonary Hypertension, Tammy Wichman Aug 2021

Superoxide And Pulmonary Hypertension, Tammy Wichman

Theses & Dissertations

Pulmonary arterial hypertension (PAH) is a devastating cardiovascular disease, which is progressive and fatal despite advances in therapy. Animal models have shown that oxidative stress may be pathogenic in PAH. We hypothesize that oxidative stress, as measured by increased levels of a specific reactive oxygen species, superoxide (O2•-), mayplay a role in PAH in humans. Using a novel application of electron paramagnetic resonance (EPR) spectroscopy, we initially evaluated whether levels of O2•- from whole blood collected from the pulmonary artery collected during right heart catheterization (RHC) would correlate with O2•- levels in peripheral …


Alcohol Drives Oxidation-Dependent Desensitization Of Airway Cilia Motility Responsiveness, Michael Price May 2018

Alcohol Drives Oxidation-Dependent Desensitization Of Airway Cilia Motility Responsiveness, Michael Price

Theses & Dissertations

Alcohol abuse, which can impair clearance of pathogens and debris from the airway, is associated with an increase in complications and a higher mortality rate during the progression of pneumonia. With prolonged alcohol exposure, mucociliary clearance (MCC), which depends on the coordinated beating of cilia, is dysfunctional. Effective MCC relies on cAMP-dependent protein kinase (PKA) activation of ciliary beat frequency (CBF). PKA activation and stimulation of CBF are blunted with chronic exposure to alcohol. This phenomenon is known as alcohol-induced ciliary dysfunction (AICD). Previous studies have shown that concomitant feeding of mice with alcohol and antioxidants prevents AICD, suggesting a …
