Evaluation Of Fall-Seeded Cover Crops For Grassland Nesting Waterfowl In Eastern South Dakota, Charles W. Gallman Iii

Electronic Theses and Dissertations

The Prairie Pothole Region is the primary breeding ground for many species of North American waterfowl. This landscape was historically dominated by mixed and tallgrass prairies interspersed with wetlands, but >70% of native grassland area has been lost due to widespread conversion to croplands, which may threaten waterfowl production. Cover cropping is a re-emerging farming technique that may provide suitable nesting cover for grassland nesting waterfowl on active farmlands. My research objectives were to evaluate the utility of fall-seeded cover crops to breeding waterfowl compared to perennial cover, determine if cover crops in rotation with row crops can successfully support …

Developing Microbial Based Process To Produce High Value Natural Antimicrobial (Glyceollin) In Soybeans And Pullulan From Sucrose, Andrea Zavadil

Electronic Theses and Dissertations

Glyceollin is a secondary metabolite produced under stress conditions by soybean to act as a plant defender to pathogen attack. The antimicrobial nature of glyceollin makes it a promising natural alternative to antibiotics if incorporated into livestock feed. However, production of glyceollin is highly variable, dependent on soybean variety, and fungal elicitor used as inoculum. Our study compares two fungal spore elicitors, Trichoderma reesei and Aspergillus sojae on soybeans of diverse maturity level, and fungal susceptibility to determine highest glyceollin titer. Spore inoculation with T. reesei elicited highest glyceollin titers of 2.42±0.20 mg/g at 120 h, while A. sojae elicited …

Neuroprotective Effects Of Cardiorespiratory Fitness On White Matter Integrity And Cognition Across The Adult Lifespan, Ryan A. Mace

Psychology Department Dissertations

Objective: Cardiorespiratory fitness (CRF) is associated with decreased risk for cognitive decline. Accumulating evidence has linked CRF to more conserved white matter (WM) integrity and better cognitive performance in older adults. Additional research is needed to determine: (1) which WM tracts are most strongly related to CRF, (2) whether CRF-related benefits on WM translate to enhanced executive functioning (EF), and (3) if the neuroprotective effects of CRF are age-dependent. This study aimed to evaluate CRF as an intervention for modulating decreased WM integrity and EF in aging. Method: Participants were community-dwelling adults (N = 499; ages 20-85) from the open-access …

The Legal Envelope Theorem, Daniel A. Weisbach, Daniel J. Hemel

Coase-Sandor Institute for Law & Economics Research Paper Series

Non-tax legal rules regulating the workplace, the 6inancial sector, real property, and many other areas affect the ability of governments to collect revenues and provide public goods. Yet tax-collection considerations rarely enter into economic analyses of non-tax legal rules. Usually, tax-collection concerns are shunted aside to separate studies (and separate law-school courses) rather than being integrated into debates in non-tax spheres. This separation between non-tax legal rules and tax- collection considerations bears signi6icant negative consequences for the ability of law and economics to generate descriptively accurate and normatively attractive accounts of important non-tax legal questions.

The Essences Of Objects: Explicating A Theory Of Essence In Object-Oriented Ontology, Stanford Howdyshell

Philosophy Faculty Publications

In this paper, I will discuss the need for a theory of essences within Object-Oriented Ontology (OOO) and then formulate one. I will do so by drawing on Graham Harman’s work on OOO and Martin Heidegger’s thought on the essence of being, presented in his Introduction to Metaphysics. Harman touches on essences, describing them as the tension between a withdrawn object and its withdrawn qualities, but fails to distinguish between essential and inessential qualities within this framework. To fill in the gaps, I will turn to Heidegger’s explication of phusis in order to show that an essential aspect of …

Mesenchymal Stem Cell Therapy Alleviates The Neuroinflammation Associated With Acquired Brain Injury, Brooke Bonsack, Sydney Corey, Alex Shear, Matt Heyck, Blaise Cozene, Nadia Sadanandan, Henry Zhang, Bella Gonzales-Portillo, Michael Sheyner, Cesar V. Borlongan

Neurosurgery and Brain Repair Faculty Publications

Ischemic stroke and traumatic brain injury (TBI) comprise two particularly prevalent and costly examples of acquired brain injury (ABI). Following stroke or TBI, primary cell death and secondary cell death closely model disease progression and worsen outcomes. Mounting evidence indicates that long-term neuroinflammation extensively exacerbates the secondary deterioration of brain structure and function. Due to their immunomodulatory and regenerative properties, mesenchymal stem cell transplants have emerged as a promising approach to treating this facet of stroke and TBI pathology. In this review, we summarize the classification of cell death in ABI and discuss the prominent role of inflammation. We then …

Neurosurgery and Brain Repair Faculty Publications

Amyotrophic lateral sclerosis (ALS) is a fatal disease of motor neuron degeneration in the brain and spinal cord. Progressive paralysis of the diaphragm and other respiratory muscles leading to respiratory dysfunction and failure is the most common cause of death in ALS patients. Respiratory impairment has also been shown in animal models of ALS. Vascular pathology is another recently recognized hallmark of ALS pathogenesis. Central nervous system (CNS) capillary damage is a shared disease element in ALS rodent models and ALS patients. Microvascular impairment outside of the CNS, such as in the lungs, may occur in ALS, triggering lung damage …

The FASEB Journal published by Wiley Periodicals LLC on behalf of Federation of American Societies for Experimental Biology Eicosapentaenoic acid (EPA) has garnered attention after the success of the REDUCE-IT trial, which contradicted previous conclusions on EPA for cardiovascular disease risk. Here we first investigated EPA's preventative role on hyperglycemia and hyperinsulinemia. EPA ethyl esters prevented obesity-induced glucose intolerance, hyperinsulinemia, and hyperglycemia in C57BL/6J mice. Supporting NHANES analyses showed that fasting glucose levels of obese adults were inversely related to EPA intake. We next investigated how EPA improved murine hyperinsulinemia and hyperglycemia. EPA overturned the obesity-driven decrement in the concentration …

Decimated Little Brown Bats Show Potential For Adaptive Change, Giorgia G. Auteri, L. L. Knowles

KIP Articles

The degree to which species can rapidly adapt is key to survival in the face of climatic and other anthropogenic changes. For little brown bats (Myotis lucifugus), whose populations have experienced declines of over 90% because of the introduced fungal pathogen that causes white-nose syndrome (WNS), survival of the species may ultimately depend upon its capacity for adaptive change. Here, we present evidence of selectively driven change (adaptation), despite dramatic nonadaptive genomic shifts (genetic drift) associated with population declines. We compared the genetic makeups of wild survivors versus non-survivors of WNS, and found significant shifts in allele frequencies of genes …

Welcome To The World Of Tomorrow: An Exploration Of Cell-Based Meats And How The Fda And Usda May Protect Intellectual Property Rights, Sean A. Grafton

Catholic University Journal of Law and Technology

Lab-grown meats are ready to be sold in United States markets. However, the meat product needs approval from regulators such as the Food and Drug Administration (“FDA”) and the United States Department of Agriculture (“USDA”). The regulation approval process takes a significant amount of time. This approval period will cut into the lab-grown meat producers’ patent time, rendering a period of the patent ineffective.

This Comment analyzes the effect of, and possible changes to, our current laws on the emerging lab-grown meat market. To look at this problem, this Comment compares FDA and USDA regulations, analyzes the Hatch-Waxman Act, and …
