Deep Radio Observations And The Role Of The Cosmic Web In Galaxy Evolution, Nicholas M. Luber

Graduate Theses, Dissertations, and Problem Reports (ETD)

A current open question in the evolution of galaxies, is what are the physical mechanisms that cut off galaxies from their primordial gas reservoirs, resulting in the end of their star-formation capabilities? Recent observational programs have shown that the properties of galaxies show dependencies on their placement within the large-scale structure (LSS) of the universe. These observations have motivated recent developments in theoretical work that have shown how a galaxy's interaction with the LSS may impact its connection to primordial gas supply, and ability to continue to accrete gas, the fundamental ingredient in star-formation.

In order to investigate the role …

The Link Between Gut Microbiota Metabolism And Host Gluconeogenesis By Vasoactive Intestinal Peptide, Razia Dawlaty

Microbiological Sciences

The gut microbiota (GM) plays a beneficial role in host metabolism. In mammals, the GM ferments dietary fiber into short chain fatty acids (SCFA), like propionate, that improves glucose metabolism. Rats fed a propionate diet increased intestinal gluconeogenic (IGN) gene expression, which was blocked by treatment with the neurotoxin, capsaicin, suggesting a neuronal-dependent mechanism. We hypothesized that the gut neuropeptide, vasoactive intestinal peptide (VIP), links GM derived propionate to IGN expression. We fed VIP deficient mice a 5% propionate chow diet (n=60) for 2 weeks and measured mRNA levels for GN genes by dPCR. Basel intestinal and liver GN mRNA …

In Search Of The Public Interest, Jodi L. Short

Faculty Scholarship

“Public interest” standards in statutory delegations to agencies represent the greatest hopes and the darkest fears of the U.S. administrative state. On the one hand, the public interest standard provides a vessel for agencies to infuse policymaking with the moral and ethical commitments of the community. On the other hand, regulation in the public interest opens the door to the arbitrary exercise of tyrannical state power. Despite the lofty aspirations and ominous warnings about regulation in the public interest, little is known about how agencies actually decide what is in the public interest when charged by statute to do so. …
