Effect Of Hyperoxia On Cardiac Pathophysiology In Female Guinea Pig Hearts, Chayapatou Chayawatto
Effect Of Hyperoxia On Cardiac Pathophysiology In Female Guinea Pig Hearts, Chayapatou Chayawatto
USF Tampa Graduate Theses and Dissertations
Hyperoxia is widely implemented in critical care and ICU patients. The administration of a high concentration of inspired oxygen to the lung can unknowingly cause hyperoxia and thereby damaging the lungs and heart due to oxidative stress. Technically, hyperoxia occurs when the patient receives PaO2 > 200 mmHg. Major research focused on hyperoxia-induced lung injury, but nothing is known on its effect on heart. Our lab is the pioneer in understanding the effect of hyperoxia on cardiovascular remodeling using mice model. Previous results show that mice under 72 hours of hyperoxia present severe cardiac pathophysiology. This research uses Guinea pigs, which …

Role Of Bmi1 In Acute Lung Injury, María Helena Hernández-Cuervo
USF Tampa Graduate Theses and Dissertations
Acute Lung Injury (ALI) is a set of signs and symptoms that lead to acute hypoxemic respiratory failure characterized by bilateral pulmonary infiltrates not attributed to cardiogenic origin. It is caused by a massive innate immune response, with the migration of white blood cells (neutrophils and macrophages principally) and a cytokine storm, followed by alterations in mitochondrial function, increase in reactive oxygen species production, and oxidative stress that in turn induces more mitochondrial damage. Several studies have shown that mitochondrial alterations are key events in the mechanism of ALI and reducing mitochondrial dysfunction could be a possible target in the …
