Design And Validation Of An In Vivo Long-Term Attachment Capsule Robot, Wanchuan Xie

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

The invention of capsule endoscopy (CE) made the non-invasive monitoring of the entire small bowel possible and became the primary means for diagnosing small bowel pathology. In the last decade, capsule robots have been transformed from diagnostic devices into a widely studied biomedical platform with the potential for active locomotion, drug delivery and therapeutic capabilities. To perform accurate on-site drug release and therapy, it is necessary for a capsule robot to be able to attach to the intestinal tissue and maintain its position long-term. Design challenges derive from the task of long-term mucosal adhesion which requires firm, quick-response attachment without …

Δ13c And Δ15n In The Endangered Kemp’S Ridley Sea Turtle Lepidochelys Kempii After The Deepwater Horizon Oil Spill, Kimberly J. Reich, Melania C. López-Castro, Donna J. Shaver, Claire Iseton, Kristen M. Hart, Michael J. Hooper, Christopher J. Schmitt

United States Geological Survey: Staff Publications

The Deepwater Horizon explosion in April 2010 and subsequent oil spill released 3.19 × 106 barrels (5.07 × 108 l) of MC252 crude oil into important foraging areas of the endangered Kemp’s ridley sea turtle Lepidochelys kempii (Lk) in the northern Gulf of Mexico (GoM). We measured δ13C and δ15N in scute biopsy samples from 33 Lk nesting in Texas during the period 2010 to 2012. Of these, 27 were equipped with satellite transmitters and were tracked to traditional foraging areas in the northern GoM after the spill. Differences in δ13C between the oldest and newest scute layers from 2010 …

Cyclosporine Exacerbates Ketamine Toxicity In Zebrafish: Mechanistic Studies On Drug–Drug Interaction, Bonnie L. Robinson, Melanie Dumas, Syed F. Ali, Merle G. Paule, Qiang Gu, Jyotshna Kanungo

United States Food and Drug Administration: Publications

Cyclosporine A (CsA) is an immunosuppressive drug commonly used in organ transplant patients to prevent allograft rejections. Ketamine is a pediatric anesthetic that noncompetitively inhibits the calcium-permeable N-methyl-^_D-aspartic acid receptors. Adverse drug–drug interaction effects between ketamine and CsA have been reported in mammals and humans. However, the mechanism of such drug–drug interaction is unclear. We have previously reported adverse effects of combination drugs, such as verapamil/ketamine and shown the mechanism through intervention by other drugs in zebrafish embryos. Here, we show that ketamine and CsA in combination produce developmental toxicity even leading to lethality in zebrafish larvae …

Developing Citizenship Through Honors, Jacob Andrew Hester, Kari Lynn Besing

Journal of the National Collegiate Honors Council Online Archive

For decades, research has shown that higher levels of education correspond to increased interest in politics and civic engagement. Despite the vast amount of scholarly attention, why this link exists is still disputed. One theory about the connection is the civic education hypothesis, which claims that the causal link between education and civic engagement depends not only on the amount of education a person receives but also on the type of curriculum studied. For example, Hillygus argues that “some courses are more likely than others to develop the skills fundamental to political participation” (31). Similarly, Condon argues that the development …

Early Head Start Home Visitor's Identification Of Risk For Maltreatment, Alayna Schreier

Department of Psychology: Dissertations, Theses, and Student Research

Infants and toddlers enrolled in Early Head Start are at increased risk for child maltreatment due to the presence of numerous factors across a developmental-ecological framework, such as poverty, parental mental health problems, and developmental disability (e.g., Belsky, 1993; Bronfenbrenner, 1979). Within Early Head Start, home visitors are in a unique position to identify the families most likely to experience maltreatment. However, research has demonstrated that home visitors are often ill-equipped to identify and address risk factors such as parental mental health concerns, substance abuse, and domestic violence (Azzi-Lessing, 2011; Tandon, Mercer, Saylor, & Duggan, 2008). Further, little is known …

Genomic Regions Involved In Seed Protein, Oil, And Carbohydrate Concentration In Soybean, Samantha J. Mcconaughy

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Soybeans [Glycine max (L.) Merr.] are processed for their high-quality vegetable oil and protein meal for feed, food, and industrial applications but, because of the high negative correlations between seed protein and oil concentration, it has been difficult to develop soybean lines with concomitant increases in both protein and oil. Previous studies considered only seed protein or oil concentration. This study is unique in that populations were developed using parental lines that differed in their protein, oil, and total carbohydrate concentrations in the mature seed. Two soybean populations were developed using soybean accession PI 547827 with lower total sugars as …

Phytohormone Signaling In Chlorella Sorokiniana: Perspectives On The Evolution Of Plant Cell-To-Cell Signaling, Maya Khasin

School of Biological Sciences: Dissertations, Theses, and Student Research

Cell-to-cell communication is a key aspect of microbial physiology and population dynamics, and a cornerstone in understanding the evolution of multicellularity. Quorum sensing in bacteria is a canonical example of microbial cell-to-cell signaling, in which bacteria use small molecule signals in order to monitor their population size and modulate their physiology accordingly. We propose that the evolution of plant hormone signaling arose in unicellular green algae, analogously to quorum sensing in bacteria, and that the complexity of these pathways required the recruitment of increasingly specific enzymes to increasingly sophisticated gene networks throughout the course of phytohormone signaling evolution. Using Chlorella …

Saving Money While Participating In Urban Agriculture, Jill Wieneke

Department of Environmental Studies: Undergraduate Student Theses

With more and more people pouring into urban areas, many have become unattached to where their food comes from and are disengaged with local food systems. Urban agriculture (UA) can bring people closer to healthy foods and be a potential savings. This will bring more resilience to a community and amend food insecurities Through this case study at the Hawley Hamlet Neighborhood Garden, urban gardeners can understand the capabilities of UA and the effects of food affordability into urban settings. This case study is an example of vegetable outputs and cost savings that can be obtained at a community garden …

Lactose Intolerance: An Overview Of The Facts And Their Implications, Noelle M. Yeo

Honors Program: Senior Projects (Public)

Lactose intolerance is often blamed for the symptoms such as bloating, diarrhea, gas, abdominal pain, and nausea, that ail many people. Patients often do not seek proper diagnosis from a physician and create their own treatment plans, severely restricting lactose intake, without professional guidance. Even those who do seek the care of a physician find that diagnosis is complicated by less-than ideal testing and confusion due to the symptoms common to many other conditions. The misconceptions and inability to confirm a diagnosis of lactose intolerance can cause nutrient deficiencies in these patients, as well as begin a pattern of unnecessary …

Effects Of Temperature And Diet In Stable Fly (Diptera: Muscidae) Development, Melina Florez-Cuadros

Department of Entomology: Dissertations, Theses, and Student Research

Stable flies are among the most important blood feeding ectoparasites of cattle worldwide. The livestock industry is losing more than $2 billion dollar annually in the United States alone. Moist decaying vegetative material with bacteria supports larval development. Temperature and diet quality are important factors for stable fly development, affecting development rates, adult survival, and size, but how temperature affects adult size and interacts with nutrition is unknown. This study characterizes the relationship of temperature and diet quality in the development of stable flies. Two statistical models were used to analyze the effect of temperature alone (Lysyk, 1998) and temperature-diet …

Feeding Preference Of Spodoptera Frugiperda (Smith) (Lepidoptera: Noctuidae) On Phaseolus Vulgaris L. Genotypes, C. A. Freitas, L. Nogueira, M. M. Freitas, P. H. S. Barcelos, A. L. Boiça Júnior

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION The species Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) is a widely distributed pest in the American continent and with a polyphagous habit, causing damage to several crops of economic importance, such as bean bean (CASMUZ et al., 2010). The most control measure to manage S. frugiperda is based on sprayings of chemical insecticides. However, alternative methods less damaging to the environment have been proposed. The host plant resistance is one of them, through plants that present in their constitution genes that are capable of producing substances that interfere in the behavior and/or development of the insect (BOIÇA JÚNIOR …

The Manteca Yellow Bean: A Genetic Resource Of Fast Cooking And High Iron Bioavailability Phenotypes For The Next Generation Of Dry Beans (Phaseolus Vulgaris L.), Jason A. Wiesinger, Karen A. Cichy, Elad Tako, Jon J. Hart, Raymond P. Glahn

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Dry beans (Phaseolus vulgaris L.) are a nutrient dense food produced globally as a major pulse crop for direct human consumption. Despite being rich in protein and micronutrients, long cooking times limit the use of dry beans worldwide, especially in regions relying on wood and charcoal as the primary sources of fuel for cooking, such as Sub-Sahara Africa and the Caribbean. Coincidently, these same regions also have high densities of women and children at risk for micronutrient deficiencies [1]. There is need for a fast cooking bean, which can positively impact consumers by reducing fuel cost and preparation time, …

Biomass And Yield Of Common Bean (Phaseolus Vulgaris L.) As A Function Of The Nitrogen Source, José Alberto Salvador Escalante-Estrada, María Teresa Rodríguez-González

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION Beans in grain (Phaseolus vulgaris L.) are important for food due to its nutritional and medicinal properties. Thus, research that generates strategies to increase the yield is justified. Nitrogen fertilization has been determinant in increasing the yield of this legume (Escalante et al., 2015a). The farmers usually fertilizes with the nitrogen source available on the market, whether ammonium sulfate, ammonium nitrate, urea, etc. However, the results may be different depending on the source of nitrogen applied as reported Binoti et al. (2009). The aim of this study was to determine the effect of the nitrogen source on the biomass, …

Exportation Rates Of Nutrients In Snap Bean With Indeterminate Growth Habit, Renan Ribeiro Barzan, João Pedro Silvestre, Hector Augusto Sandoval Contreras, Gustavo Adolfo De Freitas Fregonezi, Luiz Henrique Campos De Almeida

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION: The potential exportation of macronutrients in the harvested part of each crop is an important aspect to consider for programming the restitution of these mineral elements, avoiding their exhaustion in the soil (RAIJ, 2011). The aim of this study was to evaluate the potential exportation rates of nutrients by the harvested pods in a snap bean genotype with indeterminate growth habit, providing theoretical basis for the recommendations of restitution fertilization in the production systems with the cultivation of this vegetable crop.

MATERIAL AND METHODS: The experiment was carried in a greenhouse covered with polyethylene (150 μm thickness) in State …

Differential Response Of Fifteen Pinto Bean Cultivars To Two Nitrogen Rates, A. Alhasan, J. Heitholt

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION - Dry bean (Phaseolus vulgaris L.) is the main source of protein (20 to 25%) for most people in the world; protein from soybean is higher but is primarily use for livestock. Dry bean yield is often lower than 1000 kg ha^-1 in most dry bean producing regions except the US. Besides drought, low soil fertility and ineffective nitrogen (N) management strategies are the most important yield-limiting factors for dry bean production worldwide (Fageria et al., 2013). Use of N-efficient dry bean genotypes, optimal timing of N application(s), and identifying a costeffective N rate are good strategies …

Potassium Fertilization Influence In Anthracnose Control In Common Bean, Wallysson Nascimento Lima, Anatércia Ferreira Alves, Deurimar Herênio Gonçalves Júnior, Felipe Ferreira Da Silva, Alinne Da Silva, Wilson Araújo Da Silva

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION: The common bean (Phaseolus vulgaris L.) crop is affected by more than 200 diseases, capable to narrow the production and decrease the product quality physiological, nutritional and commercial, including anthracnose. The bean anthracnose, caused by the fungus Colletotrichum lindemuthianum (Sacc. & Magnus), is one of the most serious bean diseases, affecting susceptible cultivars worldwide (Bianchini et al., 1989). Potassium has a big relation with the incidence reduction and diseases severity in plants, acting in the inoculum potential reduction (Huber and Arny, 1985). Thus, the research objective was evaluating the severity and the bean anthracnose control under different levels …

Terminal Water Stress Imposed To Identify Drought Tolerant Mesoamerican Black Common Bean Breeding Lines In Southern Mexico, Francisco Javier Ibarra-Pérez, Rigoberto Zetina-Lezama, Oscar Hugo Tosquy-Valle, Ernesto López-Salinas

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION: Productivity of the dry bean crop is low in the humid tropical environments of southeastern Mexico, due in large part to the effect of different biotic and abiotic factors which reduce grain yield. The most important abiotic factor is the presence of terminal drought that occurs frequently after flowering, during pod filling stages and physiological maturity (Acosta-Gallegos et al., 1998), particularly in the crop season with residual moisture, which restrict yield and cause partial and severe losses in commercial crops. The development of improved varieties with resistance to this environmental factor is a viable alternative to increase yields of …

Identification Of Black Common Bean Breeding Lines Adapted To Acid Soils Of Southern Veracruz, Mexico, Oscar Hugo Tosquy-Valle, Rigoberto Zetina-Lezama, Francisco Javier Ibarra-Pérez, Ernesto López-Salinas, Aurelio Morales-Rivera

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION In the area of Isla Plains and Juan Rodríguez Clara, located south of Veracruz, Mexico, beans are sown annually in low fertility acid soils, mainly Cambisols and Acrisols, of sandy texture, with pH lower than 5.0 and organic matter content less than 1.5%, which confer a low cation exchange capacity (Zetina et al., 2002). In this type of soil, low dry black bean seed yields are obtained, which may be lower than 300 kg ha^-1, particularly when there is a combined effect of soil acidity and drought (Tosquy et al., 2008). The objective of this research …

Water Regime Effects On Phenology And Seed Yield Of Two Common Bean Cultivars Grown In Durango, México, Rigoberto Rosales-Serna, Hilario Flores-Gallardo

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION: In the State of Durango, México, common bean (Phaseolus vulgaris) is the most important food product used for direct human consumption, after grain cooking. Common bean is cultivated mainly under rainfed conditions in despite of its decisive role in local economy, human nutrition and nutraceutical contribution for human health. Under rainfed conditions water shortage (intermittent drought) and yield losses in common beans are the main factors causing negative impacts on the farmer´s economy. Some attempts have been made to use common beans under irrigated conditions in order to improve water productivity and to stabilize seed yield. …

The Role Of Stress Factors In Skeletal Muscle Development, Growth, And Metabolism; Impacts Of Temporally Spaced Repetition On Long-Term Information Retention In An Anatomy And Physiology Course, Caitlin N. Cadaret

Department of Animal Science: Dissertations, Theses, and Student Research

We sought to identify the effect of sustained maternal inflammation at mid-gestation on fetal mortality, skeletal muscle growth, and development at term. Fetal rats had reduced total mass that coincided with impaired myoblast function, as myoD was reduced and myogenin expression was increased in hindlimb muscle. Fetuses also had increased circulating TNFα at term after maternal inflammation, which decreased TNFR and IL6R mRNA in muscle, reducing sensitivity to cytokines. These findings indicate that sustained maternal inflammation at mid-gestation impairs fetal skeletal muscle growth near-term due to changes in myoblast responsiveness to inflammatory regulation.

To evaluate the acute impact of inflammatory …
