How To Be The Perfect Asian Wife!, Sophia Hill

Art and Art History Honors Projects

“How to be the Perfect Asian Wife” critiques exploitative power systems that assault female bodies of color in intersectional ways. This work explores strategies of healing and resistance through inserting one’s own narrative of flourishing rather than surviving, while reflecting violent realities. Three large drawings mimic pervasive advertisement language and presentation reflecting the oppressive strategies used to contain women of color. Created with charcoal, watercolor, and ink, these 'advertisements' contrast with an interactive rice bag filled with comics of my everyday experiences. These documentations compel viewers to reflect on their own participation in systems of power.

Elemental Analysis Of Beer Manufactured In Virginia Satellite Breweries, Jennifer Wiliams

Student Scholar Showcase

Financial incentives from the state and wider distribution potential have lured many west coast brewers to open satellite breweries in Virginia. Quality control is crucial for any brewery and especially important in satellite breweries that need to imitate the standard set by the parent brewery. Zinc, magnesium, iron, sodium manganese, and calcium are trace elements found in wort and are essential for enzymes that catalyze fermentation reactions. These elements protect against cell stress, play a crucial role in flocculation, and can affect the flavoring and coloration of beer. Barley, water, and hops are the sources of these elements in beer. …

Whole Tart Cherry Improves Disease Activity Index In Rat Model Of Dextran Sulfate Solution – Induced Ulcerative Colitis By Downregulating The Janus 1 And Janus 3 Kinases And Tnf - Alpha, Johana Alexandra Coronel

LSU Master's Theses

Ulcerative colitis (UC) is a disabling inflammatory bowel disease. UC is characterized by chronic, relapsing inflammation of the colon and rectum. Current treatments such as monoclonal antibodies against TNF-α, IL-6, IL-12/p40, adhesion molecules, Janus kinases (JAK) inhibitors have side effects or lose their effects over time. Alternative approaches with fewer side effects for patients are needed. Montmorency tart cherries (Prunus cerasus) are a good source of anti-inflammatory flavonoids. We hypothesized that regular consumption whole tart cherry (TC) standardized to its major anthocyanin content, namely cyanidin-3-glucosyl-rutinoside, would be effective in reducing inflammation in UC.
