Design Of A 3d Printed Bioreactor For Bone Cancer Research, Brooklyn K. Vanderwolde, Katelyn Hillson

The Journal of Undergraduate Research

Bone cancer is an aggressive disease and has peak occurrence during physiological stimulation of growth and aging. Astronauts who undergo long-term space missions also acquire an increased risk of bone tissue degeneration and cancer. Few in-vitro models currently exist capable of reproducing the complex microenvironment of bone tissue to support multicellular activity in a three-dimensional structure. This limits the ability to understand disease progression and develop suitable treatment strategies. Therefore, developing a bone tissue model and an associated bioreactor is critical to understand the risks associated with cancer progression and improve treatment and preventions related to those risks. The goal …

Influence Of Six Herbicides Applied To Silage Corn On Fall Planted Rye And Radish Cover Crop Growth In South Dakota Soils, Sydney Pridie

With global pollinator decline continually worsening as a result of human action, concerned citizens and scientists alike have been looking for answers as to what can be done to help, and the question of whether native or non-native plants provide more benefit to pollinating insects has been long discussed in the scientific community. This research is intended to help answer that question by attempting to determine whether pollinators have a distinct preference between native and non-native plants when presented with both options. The hypothesis at outset of this project was that native plants would provide greater benefit to pollinators, whom …

Development And Diagnostic Application Of Monoclonal Antibodies Against Swine Acute Diarrhea Syndrome Coronavirus (Sads-Cov), Molly Kroeger

Schultz-Werth Award Papers

Swine Acute Diarrhea Syndrome Coronavirus (SADS-CoV) is a member of the Coronaviridae family. The virus is associated with severe small intestine inflammation and diarrhea in suckling piglets. In 2017, SADS-CoV was first detected and identified as the causative agent of a devasting swine disease outbreak in southern China. Routine monitoring and early detection of the source of infection is therefore integral to the prevention and control of a SADS-CoV outbreak in the United States. However, the United States does not currently have any diagnostic or surveillance tests to identify this emerging disease. To address these industry needs, we developed monoclonal …

Evaluation Of Anterior Pituitary Leptin Receptor Expression In Pregnant And Non-Pregnant Gilts, Juliana Pederson, Jeffrey Clapper

Schultz-Werth Award Papers

Successful reproduction in porcine depends on the coordinated synthesis and release of several hormones from the hypothalamus and anterior pituitary gland. Leptin, a hormone produced from adipocytes, interacts with other specific reproductive hormones and affects the reproductive success in swine. However, the full extent of leptin’s impact is unclear. This experiment sought to examine the difference in expression between the anterior pituitary gland leptin receptors in pregnant and non-pregnant pigs to confer the impact leptin has on reproductive success. Twentyfour crossbred gilts of similar age and weight had their estrus cycles synchronized and then were bred via artificial insemination. The …
