Editing Approaches To Treat Alpha-1 Antitrypsin Deficiency, Derek M. Erion, Leah Y. Liu, Christopher R. Brown, Stephen I. Rennard, Humam Farah

Journal Articles: Pulmonary & Critical Care Med

TOPIC IMPORTANCE: Alpha-1 antitrypsin (AAT) deficiency is a genetic disorder most commonly due to a single G to A point mutation (E342K), leading to debilitating lung and/or liver disorders and is associated with increased mortality. The E342K point mutation causes a conformational change of the AAT protein resulting in its retention in liver hepatocytes. This reduces AAT secretion into the serum resulting in higher protease activities due to the lack of inhibition from AAT, causing damage to healthy lung tissue. The current standard of care for lung manifestations involves weekly IV augmentation therapy and is considered suboptimal for these patients. …

Impact Of Geography On Institutions In Agricultural And Nomadic Societies, Haiwen Zhou

Economics Faculty Publications

How geography affects the choice of institutions is studied in a theoretical model. In this model, nations are located around a circle. Rulers compete through choosing tax rates, the level of military spending, and the degree of formality of institutions. Geographic condition is captured by population density. It is shown that societies with higher population densities choose lower tax rates, establish more formal institutions, and give government officials lower levels of autonomies than those with lower population densities do. A higher level of external threats induces a ruler to choose a higher level of autonomy for officials. The model is …
