The Chemistry Of The Flint Water Crisis, Ernest M. Oleksy

The Downtown Review

Politics and science do not always go hand-in-hand. Nowhere was this more clear than in the Flint Water Crisis. Negligence towards growing levels of lead poisoning in drinking water led to incredibly deleterious effects on Flint's citizens. The chemistry of equilibrium and the shortcomings of local leaders led to Flint's water becoming a crisis.

Profiling Cell Surface Sialylation And Desialylation Dynamics Of Immune Cells, Dan Wang

ETD Archive

Sialic acids (SAs) are a diverse family of naturally occurring 2-keto-3-deoxy-nononic acids that are involved in a wide range of biological processes, including early fetal development, cellular recognition, and utilization by microbes. While it is clear that cell surface SAs are highly involved in the immune system, the sialylation status of individual immune cells and functions are still unknown. In this study, I combined the newly developed LC-MS/MS methods with flow cytometry and confocal microscopy to systematically study the sialylation and desialylation dynamics of macrophages at different conditions.

First, I developed an accurate LC-MS/MS method to quantify free SA in …
