The Retinal Immune Response To Injury And Protein Misfolding: Insights From Models Of Traumatic Brain Injury, Parkinson’S Disease, And Prion Disease., Najiba Mammadova Jan 2019

The Retinal Immune Response To Injury And Protein Misfolding: Insights From Models Of Traumatic Brain Injury, Parkinson’S Disease, And Prion Disease., Najiba Mammadova

Graduate Theses and Dissertations

Retinal manifestations have been described in several neurodegenerative insults and disorders. The strong similarities between the retina and the brain and the accessibility of the retina has potentiated studies to investigate retinal pathology in an effort to identify biomarkers for early diagnosis, as well as for monitoring the progression of disease and efficacy of therapies as they become available. However, there is a limited understanding of retinal pathological landmarks of disease progression.

In the studies conducted in this dissertation, we investigate retinal changes associated with ocular blast injury, and protein-misfolding - in a mouse model of Parkinsonism, and in bovine spongiform ...


Effect Of Spatial And Non-Spatial Changes On Perceived Self-Location, Lucia Annaleigh Cherep Jan 2019

Effect Of Spatial And Non-Spatial Changes On Perceived Self-Location, Lucia Annaleigh Cherep

Graduate Theses and Dissertations

Place cell activity is measured through single-cell recording in animals, though place-responsive cells and related properties have been identified in the human hippocampus. Human behavioral studies would strengthen these findings, especially given the challenge of conducting neuroscientific research on human place-responsive cells. The current study was based on the finding (Lenck-Santini et al., 2005) that rodent place cells partially remap after spatial environmental changes (rotating objects relative to enclosure) but are unaffected by non-spatial changes (object substitution). In two completed studies, human perceived self-location was evaluated in response to spatial and non-spatial changes in a virtual environment (VE). Participants studied ...

Quantifying The Effects Of Light Quantity And Quality On Culinary Herb Physiology, Alexander Gaston Litvin-Zabal Jan 2019

Quantifying The Effects Of Light Quantity And Quality On Culinary Herb Physiology, Alexander Gaston Litvin-Zabal

Graduate Theses and Dissertations

Lighting influences plant growth and development on a quantity and quality basis, promoting the production of both primary and secondary metabolites. While the amount of light necessary for culinary herb production is species-specific, with growth curves for increasing daily light integrals (DLI), the specific spectra of incidental light absorbed plays a role in photosynthetic efficiency, biomass partitioning, and secondary metabolites related health and nutrition. The two primary objectives of this research were to 1) Quantify morphological growth of culinary herbs under increasingly higher DLI, and 2) Identify the morphological, physiological, and phytochemical responses of selected herbs to the spectral composition ...

Electrical Sensor Development For The Dielectric Properties Measurement And Moisture Content Estimation Of Switchgrass And Corn Stover, Augusto Cesar Magalhaes De Souza

Graduate Theses and Dissertations

The dielectric properties of material play a relevant role when developing moisture content sensors of agricultural products. However, little is known about the permittivity of switchgrass and corn stover in a wider frequency band. Thus, this research goal was to determine their dielectric constant and loss factor at different moisture contents and frequency range of 5 Hz to 13 MHz. Also, an electrical sensor system was developed to predict the amount of water in agricultural products with the material static and in movement.

The dielectric properties of switchgrass and corn stover were calculated by measuring their admittance using an impedance ...

Graduate Theses and Dissertations

Objectives were to evaluate the effects of rumen-protected glucose supplementation on milk production, post-absorptive metabolism, and inflammatory biomarkers in transition dairy cows. Fifty-two multiparous cows were blocked by previous 305 mature equivalent milk yield and randomly assigned to one of two iso-energetic and iso-nitrogenous treatments: 1) control diet (CON; n = 26) or 2) a diet containing RPG (RPG, pre-fresh 8.4% RPG DM basis, post-fresh 9.5% RPG DM basis; n = 26). Cows received their respective dietary treatments from d -21 to 28 relative to calving. Weekly body weight (BW), milk composition, and fecal pH were recorded until 28 d ...


Evaluating Boom Height Control Performance With Variable Boom Roll Damping In A Suspended Boom System On Self-Propelled Sprayers, Evan Mellott Jan 2019

Evaluating Boom Height Control Performance With Variable Boom Roll Damping In A Suspended Boom System On Self-Propelled Sprayers, Evan Mellott

Graduate Theses and Dissertations

In this research, a method for improving spray boom height stability was developed and tested. Self-propelled sprayers played a critical role in agriculture by applying chemicals to crops to control the presence of weeds and pests. The spraying process needed to be controlled in a manner such that the spray boom maintained the necessary target height for uniform coverage. Deviation from target height allowed outside factors such as wind to become more prevalent during chemical application which generated opportunities for spray drift to occur and potentially harm neighboring crops and environment.

On a suspended spray boom system, terrain influences on ...


Disease And Insect Pest Management In Organic Cucurbit Production, Hayley Nelson Jan 2019

Disease And Insect Pest Management In Organic Cucurbit Production, Hayley Nelson

Graduate Theses and Dissertations

Organic production of cucurbit crops in the Midwest is limited by several insect pests (e.g., striped cucumber beetle, spotted cucumber beetle, squash bug, squash vine borer) and the bacterial diseases they vector (e.g., cucurbit bacterial wilt and cucurbit yellow vine disease (CYVD)). Current management strategies – low tunnels and insecticides – fail to provide reliable protection, are not durable, and are harmful to beneficial insects such as pollinators. Organic producers in the Midwest need more effective pest management options to consistently produce cucurbit crops.

A 3-year field experiment aimed to develop new row cover strategies for full-season, organic control of ...


Characterization And Application Of Arkansas Male Sterile Lines For Hybrid Rice Production, Dustin North Jan 2019

Characterization And Application Of Arkansas Male Sterile Lines For Hybrid Rice Production, Dustin North

Graduate Theses and Dissertations

Hybrid rice production using the two-line system requires developing environment genetic male-sterile (EGMS) lines which become male sterile in certain environmental conditions. EGMS lines contain genes that can be induced to express male sterility by temperature (TGMS), day length (PGMS), or both (PTGMS). Eight EGMS were tested including four lines designated as 236s, 801s, 805s, and 811s developed by the University of Arkansas System Division of Agriculture's Rice Research and Extension Center (RREC) near Stuttgart, Ark.; and four mutant male-sterile lines designated as GSOR 1, GSOR 2, GSOR 3, and GSOR 4 developed by the Dale Bumpers National Rice ...


The Role Of Cholecystokinin, Fasting Glucose, And Ketone Bodies On The Pathogenesis Of Alzheimer’S Disease, Alexandra Plagman Jan 2019

The Role Of Cholecystokinin, Fasting Glucose, And Ketone Bodies On The Pathogenesis Of Alzheimer’S Disease, Alexandra Plagman

Graduate Theses and Dissertations

Hypometabolism of glucose in the brain is associated with the neurodegenerative disorder, Alzheimer’s disease (AD), warranting further study of the relationship between metabolic function and structural integrity of the brain. While demyelination is observed with AD, less is known about the impact of glucose levels in combination with genetic risk factors on myelination. Ketone bodies are the brain’s alternative fuel source during periods of low fuel such as in Alzheimer’s disease (AD). Demyelination of the brain may lead to accumulations of amyloid beta plaques, associated with the disease (Bartzokis et al., 2007). Individuals with a family history ...


Quantifying Resilience In Sows And Wean-To-Finish Pigs, Austin Michael Putz Jan 2019

Quantifying Resilience In Sows And Wean-To-Finish Pigs, Austin Michael Putz

Graduate Theses and Dissertations

Resilience is defined as the ability of an animal to maintain a high level of performance in any environment. Swine breeding companies are organized in a pyramid-like structure. As a result of management differences between the different tiers of the pyramid, genotype-by-environment (GxE) interactions have become a much bigger issue that continues today. Genetic selection for resilience can be accomplished in at least two ways, i) measuring indicator traits in the nucleus, such as antibody levels, and ii) measuring performance phenotypes in commercial testing herds. Both of these techniques provide opportunities to improve resilience in livestock.

Total lost productivity in ...


Vitamin D Metabolites And Their Intestinal Responses, Carmen J. Reynolds Jan 2019

Vitamin D Metabolites And Their Intestinal Responses, Carmen J. Reynolds

Graduate Theses and Dissertations

Vitamin D metabolites regulate calcium absorption in the intestines through activation of the vitamin D receptor (VDR) and resulting in increased expression of calcium-associated proteins. Presently, it is thought that vitamin D metabolizes into a hormonal form, 1,25-dihydroxyvitamin D (1,25D), and the hormone then circulates via blood to the duodenum to stimulate calcium absorption. Recently, Koszewski et al. proposed that delivery of the hormone occurs via digestive passage rather than by the blood (Koszewski et al., 2012). Growing evidence has suggested, instead, that the hormonal precursor, 25-hydroxyvitamin D (25D), may have functional activity by either providing substrate for ...


A Statistical Analysis Of Zea Mays Grain Yield Response To Nitrification-Inhibitor Amendments Under Field Conditions Utilizing Parametric And Non-Parametric Techniques, Elliot H. Sully Jan 2019

A Statistical Analysis Of Zea Mays Grain Yield Response To Nitrification-Inhibitor Amendments Under Field Conditions Utilizing Parametric And Non-Parametric Techniques, Elliot H. Sully

Graduate Theses and Dissertations

Nitrification is a matter of economic and ecological importance in nitrogen-tensive agricultural practices such as corn (Zea mays) grain production. When ammonium is bacterially oxidized into nitrate it becomes more susceptible to leaching and denitrification as nitrous oxide. The nitrification process not only adds to water and air pollution but also impacts on farm productivity by reducing grains yields and increasing fertilizer demands. Nitrification inhibiting fertilizer amendments can potentially improve grain yields by retarding the growth of nitrifying soil bacteria. Multiple field studies conducted across various locations and timespans have generated mixed results regarding the grain yield difference attributed to ...


Influence Of Stress Induction On Trace Mineral Homeostasis And Metabolism In Ruminants, Katherine Vanvalin Jan 2019

Influence Of Stress Induction On Trace Mineral Homeostasis And Metabolism In Ruminants, Katherine Vanvalin

Graduate Theses and Dissertations

Cattle are exposed to stressors throughout the production cycle, many of which occur simultaneously. These stressors may include weaning, transportation, vaccination, and arrival into the feedlot which can be associated with co-mingling, as well as adaptation to dietary changes. Furthermore, these factors can create numerous challenges in terms of supplying adequate trace mineral nutrition to cattle, as these periods are also associated with decreased feed intake, which can further exacerbate a trace mineral deficiency. However, there is limited understanding of how stress impacts trace mineral homeostasis in the ruminant. Thus, by improving our understanding of alterations to trace mineral homeostasis ...


Application Of Precise Genome Editing Tools In The Zebrafish Model To Elucidate Protein Function With Regards To Developmental Phenotypes, Jordan Michael Welker Jan 2019

Application Of Precise Genome Editing Tools In The Zebrafish Model To Elucidate Protein Function With Regards To Developmental Phenotypes, Jordan Michael Welker

Graduate Theses and Dissertations

Genetic engineering is a powerful tool for biologists and geneticists to study the natural world. In general, it allows for asking and answering precise gene or DNA level questions about biological systems. The drawback of genetic engineering is that many applications requires a deep knowledge of multiple disciplines from biology to chemistry, which can make it inaccessible. Here I give a brief history of the field and define four tenets of necessary actions to begin engineering DNA, and four classes of applications using genetic engineering. I present three papers that define an accessible method of genome editing using CRISPR/Cas ...

Purpose: To evaluate the independent and combined associations of cardiorespiratory fitness (CRF) and muscular strength (MS) with arterial stiffness (AS) in older adults.

Methods: This cross-sectional study included 427 older adults aged ≥65 years (mean age 72). CRF was assessed by time (seconds) to complete a 400-m walk test and MS by overall grip strength (maximum out of 3 trials on each hand, averaged; Jamar Plus+ 12-064). Carotid-femoral pulse wave velocity (PWV) was used to assess AS (AtCor, Sphygmocor Xcel). High AS was defined as a PWV of 10 m/s or greater, as it has been established as a ...


Algorithms For Synteny-Based Phylostratigraphy And Gene Origin Classification, Zebulun Arendsee Jan 2019

Algorithms For Synteny-Based Phylostratigraphy And Gene Origin Classification, Zebulun Arendsee

Graduate Theses and Dissertations

With every newly sequenced species we discover hundreds of novel protein coding genes. Many of these "orphan" genes have been experimentally proven to have dramatic functions in development, sexual dimorphism, pathogen resistance, and social traits like symbiosis. Whereas in the past, researchers viewed genes as the product of continuous variation acting on ancient material, we now know that novel genes may arise de novo from non-genic sequence. Thus evolutionary experimentation is not limited to tweaking existing genes or their regulatory patterns. Any orphan genes that arose in the distant past, should appear today as lineage-specific genes (or gene families). The ...


Effects Of Preseason Concussion Education On Self-Reported Likelihood And Confidence In Concussion Reporting, Dana Edward Cash Jan 2019

Effects Of Preseason Concussion Education On Self-Reported Likelihood And Confidence In Concussion Reporting, Dana Edward Cash

Graduate Theses and Dissertations

Around three million concussions happen in the United States from sport and recreational activity alone, and it is estimated 50% of concussions go undiagnosed. Collegiate athletes have been found to not report their symptoms of concussion mainly because they felt their symptoms were not severe enough and they did not think there were any long-term consequences from continuing to play. This study attempts to find if preseason concussion education for collegiate hockey players and club athletes changes their perceptions about concussions, and if these changes are maintained after returning to sport/competition. This study used three identical surveys over three ...

In this dissertation, I study strategies for local and alternative food initiatives to advance more just and equitable approaches to food insecurity. My research focuses on one emerging type of local food initiative designed to address food insecurity, community donation gardening. I engaged in a three-year feminist and ethnographic study of a community-run and USDA- and Cooperative Extension-sponsored donation gardening and food rescue program, Growing Together Iowa. In Growing Together, community gardeners grow or glean food to distribute directly to community members experiencing food insecurity or alternatively to donate to partnering emergency food organizations, such as area food pantries. I ...


Uhf Band Attenuation Through A Corn Canopy With Crop Growth, Richard Jay Cirone Jan 2019

Uhf Band Attenuation Through A Corn Canopy With Crop Growth, Richard Jay Cirone

Graduate Theses and Dissertations

Soil moisture and vegetation remote sensing measurements can be inaccurate and/or misinterpreted in the US Corn Belt, specifically when considering seasonal variation in standing vegetation. A direct crop water measurement method was employed to assist in correction of satellite measurements, specifically to SMOS and SMAP. A 433 MHz radio link was installed in a central Iowa cornfield, shortly after planting, across a distance of 50 meters, for the purpose of measuring attenuation by crop water. This experiment ran until mid grain fill, development stage R3. Vegetation water column density increased from essentially 0 at planting to just above 4 ...


Comparison Of Shockwave Aerification And Conventional Aerification Methods On Athletic Fields, Timothy O. Dalsgaard Jan 2019

Comparison Of Shockwave Aerification And Conventional Aerification Methods On Athletic Fields, Timothy O. Dalsgaard

Graduate Theses and Dissertations

Providing a safe and attractive playing surface should be the goal of every athletic field manager. Athletic field use is growing faster than budgets that maintain them. With the added use, there is extra demand on the playing surface, including wear and soil compaction. Developing turfgrass management that better maximizes the playing surface quality and safety is necessary. Soil compaction from repeated foot traffic can limit recovery and increase surface hardness. Many of the methods to eliminate surface hardness are limited to the off-season due to the amount of surface disruption. The Shockwave linear decompaction device offers a tool that ...

Phenotypic And Molecular Characterization Root System Architecture In Diverse Soybean (Glycine Max L. Merr.) Accessions, Kevin G. Falk Jan 2019

Phenotypic And Molecular Characterization Root System Architecture In Diverse Soybean (Glycine Max L. Merr.) Accessions, Kevin G. Falk

Graduate Theses and Dissertations

Root system architecture (RSA), or the spatial arrangement of the root and its morphology, functions to anchor the plant, provide water and nutrient acquisition, nutrient storage and to facilitate plant-microbe interactions such as nodulation in legumes such as soybean [Glycine max L. Merr.)]. Root structure also correlates to environmental advantages, such as nutrient acquisition, drought, flood tolerance, and lodging resistance. After centuries of indirect selection for RSA, there is a focus to harness soybean RSA diversity for exploitation and implementation into cultivar development programs. Researchers have generally taken one of three strategies to approach root phenotyping including controlled laboratory, moderately ...


Design And Rapid Prototyping Of Printed Graphene Electrochemical Biosensors For Sensitive Monitoring Of Pesticide Levels For Agricultural Use, John Hondred Jan 2019

Design And Rapid Prototyping Of Printed Graphene Electrochemical Biosensors For Sensitive Monitoring Of Pesticide Levels For Agricultural Use, John Hondred

Graduate Theses and Dissertations

While the use of pesticides (herbicides and insecticides) are critically important to meet the current and future food demands (increases crop yield by up to 40%), their overuse has shown long-term detrimental impacts on the environment from polluting watersheds used for drinking water to eutrophic “dead zones”. Current pesticide soil measurement methods (chromatography) are costly, require trained technicians, and take days to analyze; thus, farmers are taking an “over-application approach” which is pollution the environment and waterways. A disposable pesticide soil sensor would provide farmers the opportunity of precisely regulating the application of pesticides in an independent and economical fashion ...

Plant scientists are beginning to harness the capabilities of high dimensional ‘omic tools (e.g., genomic, phenomic) to usher in the era of digital agriculture to allow the usage of predictive analytics. While genomic tools have been developed to exploit high-density genetic markers for breeding decision making, a gap persists in the availability of phenomic-assisted breeding methodologies. Here we develop frameworks malleable to crop species and breeding objective to leverage complex high-dimension phenomic data using machine learning (ML) and optimization techniques for the development of data driven solutions designed to empower plant scientists to; develop prescriptive breeding solutions, improve the ...


Food Security And Dietary Acculturation Among College Students At Iowa State University, Molly B. Hiller Jan 2019

Food Security And Dietary Acculturation Among College Students At Iowa State University, Molly B. Hiller

Graduate Theses and Dissertations

The food security status of college students has a lasting impact during and after their college career. The level of food security has an impact on their diet and their ability to perform in class, and ultimately shapes their eating habits for the rest of their adult life. The Dietary Guidelines from 2010 suggest consuming at least five servings of fruits and vegetables (FV) per day, at least 20 grams of fiber per day, and less than 30% of total daily calories from fat. International college students coming to the United States to study are experiencing the same dietary changes ...
