Emergence Of Zoos In The U.S. And A Search For The Exotic, Austin M. Hutchinson
Emergence Of Zoos In The U.S. And A Search For The Exotic, Austin M. Hutchinson
Student Scholar Showcase
The emergence of zoos in twentieth century America had many factors that contributed to their mission, success, and overall exotic nature. Zoos have been a part of human civilization for centuries, but it would not be until 1876 when the first zoo would appear in the United States. Individuals craved excitement and the use of exotic animals from all over the world became an important component of what zoos would become. This era coincides with the European colonization of Sub-Saharan Africa, known as the Scramble for Africa. Animals were brought from the so-called “Dark Continent” to be put on display, …
Sirna Knock-Down Of Vav1 In Breast Cancer Cells: Effects On Pi3kinase And Akt, Tajai Sion-Milligan
Sirna Knock-Down Of Vav1 In Breast Cancer Cells: Effects On Pi3kinase And Akt, Tajai Sion-Milligan

One in eight women in the United States will be diagnosed with breast cancer. Approximately 25-30% of these breast tumors will overexpress Human Epidermal Growth Factor Receptor 2 (HER2), associated with a worse prognosis and decreased survival rate. Stimulation of HER2 results in activation and production of many signaling molecules, ultimately resulting in increased cell division. Two of the downstream molecules activated are PI3Kinase and, further downstream, the molecule Akt. Typically, overproduction and/or overactivation of PI3Kinase can lead to oncogenesis. A molecule that may have a significant role in PI3Kinase formation is VAV1. VAV1 …

Evaluating Effects Of Gene Mutation And Light Intensity On Arabidopsis Thaliana Development, Carolanne Bekus
Evaluating Effects Of Gene Mutation And Light Intensity On Arabidopsis Thaliana Development, Carolanne Bekus
Student Scholar Showcase
The completion of sequencing Arabidopsis thaliana’s genome has led to the next crucial challenge of determining gene function in these plants. A. thaliana is a model organism often compared to commercial crops. The discovery of gene function within these plants will aid in giving insight on how gene function can affect commercial crop production. Presented here is an analysis comparing wild-type Columbia (Col-O), to single gene mutants when knocking-out transcriptional factors VPI/ABI3-like 1 (val1) and basic region/leucine zipper motif (bZIP). These single gene mutations may affect several traits that in turn can result in morphological changes and/or …
Analysis Of Downstream Signaling Of Tlrs After U0126 Inhibition, Brandy Frazier
Analysis Of Downstream Signaling Of Tlrs After U0126 Inhibition, Brandy Frazier
Student Scholar Showcase
Francisella tularensis (F. tularensis) is a pathogenic bacterium which causes the disease tularemia. F. tularensis is thought to be able to enter and multiply inside of liver cells because it interacts with toll-like receptors (TLRs). Examining the signaling pathway downstream of the TLRs will allow for better understanding of how this disease works and possible treatment strategies. In this study I propose to examine how molecular inhibitors affect signaling downstream of TLRs in HepG2 cells treated with lipopolysaccharides (LPS) from E. coli. Mitogen-activated protein kinase is a cellular molecule in signaling cascades that directs cellular response mechanisms. MAPK can be …
Eating Crickets? Nutrient Mineral Content Of Two Cricket Species And Chapul Cricket Protein Bars Using Mp-Aes, Nathan Hopkins
Eating Crickets? Nutrient Mineral Content Of Two Cricket Species And Chapul Cricket Protein Bars Using Mp-Aes, Nathan Hopkins
Student Scholar Showcase
Global agriculture is beset by numerous challenges which must be surmounted to feed a developing world, from combating climate change to the cultivation of sustainable food products. This, in addition to protein and nutrient deficiencies in the developing world, makes considering alternative protein sources, such as a crickets, an attractive option. Crickets use a fraction of the land and water that protein sources like beef cattle do, and can be cultivated in urban environments in stacked boxes. This research investigation aims to quantify the nutrient mineral content (Iron, Sodium, Potassium, Calcium, and Magnesium) of two cricket species (Acheta domesticus …
Elemental Analysis Of Beer Manufactured In Virginia Satellite Breweries, Jennifer Wiliams
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. …
