Lung Injury and Repair

Drs. Piantadosi, Welty-Wolf, Carraway). Animal models have been developed to study acute lung injury due to oxygen toxicity and sepsis. Methods of assessment include gas exchange (blood gases and multiple inert gas elimination), mechanics, lung morphometry, and measurement of pulmonary inflammatory responses and activation of the coagulation system. In addition, mechanisms or systemic organ injury, …

Mitochondrial Biogenesis and CO

Doxorubicin disrupts cardiac mitochondrial biogenesis, which promotes intrinsic apoptosis, while CO/HO promotes mitochondrial biogenesis and opposes apoptosis, forestalling fibrosis and cardiomyopathy (A) Representative gross and microscopic pathology. Left column: Cross-sections of mouse hearts fixed at a constant intracavitary pressure illustrate DOX-induced cardiomyopathy after 14 days. Normal mouse heart (control), CO control (CO), and DOX cross-sections …

Altitude Research

Effect of Altitude Acclimatization on Lung NO and CO Concentration and Vascular Tone in Humans (Drs. Bar-Yosef, Piantadosi, Moon). A joint study with members from the Department of Medicine examining the hypothesis that PO2-related changes in pulmonary and systemic vascular resistance in humans are mediated by changes in pulmonary NO and CO content. Analysis is …
