Design Of A 3d Printed Bioreactor For Bone Cancer Research, Brooklyn K. Vanderwolde, Katelyn Hillson May 2020

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

The Journal of Undergraduate Research

Spring preemergence herbicide applications are often used for burndown of existing weeds and residual control, eliminating weed presence during early season crop growth. There has been an increase in the interest in planting cover crops soon after cash crop removal, due to the potential soil and production benefits. However, soil herbicide residuals may result in poor cover crop growth. This study examined the growth of radish (Raphanus sativa) and rye (Secale cereal), species often used as cover crops, in soils that had been treated with residual herbicides about 100 d prior to cover crop planting. The herbicides were applied at ...

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 ...

Comparative Optic Nerve Head Physiology: Glaucoma Induced Retinal Ganglion Cell Apoptosis By Disruption Of The Translaminar Pressure Gradient And Reduced Neurotrophic Signaling, Cassidy Christopherson

Biology and Microbiology Graduate Students Plan B Research Projects

Glaucoma is the leading cause of irreversible blindness, and the second leading vision loss neurodegenerative disease affecting millions worldwide. Glaucoma is characterized as a group of eye disorders which are initially asymptomatic but may progress to significant optic nerve head damage and vision loss with time. Early stages of glaucoma often go undetected, leading to irreversible damage to the optic nerve head prior to patients seeking medical care. Glaucoma leads to vision loss via death of retinal ganglion cells. Retinal ganglion cell apoptosis is thought to begin due to interference with the normal transmission of neurotrophic signals that arrive by ...

Identification And Genomic Characterization Of Candidate Starch And Lactate Utilizing Bacteria From The Rumen Of Beef Cattle, Venkata Bandarupalli Jan 2020

Identification And Genomic Characterization Of Candidate Starch And Lactate Utilizing Bacteria From The Rumen Of Beef Cattle, Venkata Bandarupalli

Electronic Theses and Dissertations

The rumen functions as an anaerobic fermentation chamber where microbial communities ferment feedstuffs into SCFAs. These SCFAs are critical to the ruminant host since they fulfill 70% of its energy requirements. In intensive management systems, ruminants are fed with grain-rich diets, which contain high levels of starch that help meet the energy demands of high producing animals. When grain-based diets are fed to ruminants, ruminal amylolytic and lactate metabolizing bacteria predominate. Grain overload can cause rapid production and accumulation of lactate, resulting in proliferation of amylolytic bacteria and death of lactate metabolizing bacteria. Consequently, high lactate levels result in a ...

Winter Patch Grazing, Patch Burn Grazing, And Bird Communities In Western South Dakota, Jennifer Lutze Jan 2020

Winter Patch Grazing, Patch Burn Grazing, And Bird Communities In Western South Dakota, Jennifer Lutze

Electronic Theses and Dissertations

Ground nesting bird species are on a considerable decline and research efforts are being made to increase these populations throughout the Great Plains. Ground nesting bird communities found in the Northern Great Plains are driven greatly by varying amounts of cover and area size. Past research implemented patch-burn grazing to increase structural heterogeneity and to increase grassland bird habitat in the tallgrass prairie. While bird populations were very responsive to this management in the Northern Great Plains fire management is viewed negatively, especially for Midwest cattle ranchers. We implemented research to determine if winter-patch grazing on mixed grass prairie could ...
