Oral Health During Pregnancy: Promoting Awareness Of Guidelines And Education Resources In The Evaluation Of Self-Perceived Efficacy To Educate, Screen, And Refer Women During Pregnancy For The Nurse Practitioner Student, Leah Salmans
Doctoral Scholarly Projects & Capstones
Historically, oral health (OH) care has been largely misunderstood and excluded from the realm of primary care. However, this exclusion is at odds with the fact that oral health can and does have an impact on individuals’ general health and well-being. Oral disease is considered one of the most widespread chronic diseases, despite being highly preventable. For women, pregnancy can set the stage for oral disease development or exacerbation due to multiple factors. Poor maternal oral health has been associated with adverse pregnancy outcomes, contributing to early dental caries development in their children, and detrimental effects over her lifespan. To …

Survival And Inactivation Of Salmonella Enterica Serovar Typhimurium On Food Contact Surfaces During Log, Stationary And Long-Term Stationary Phases, Dorra Djebbi-Simmons, Wenqing Xu, Marlene Janes, Joan King
Faculty Publications
One of the most important transmission routes of foodborne pathogens is through contaminated food contact surfaces. In this study, we investigated the survival and inactivation of Salmonella enterica serovar Typhimurium on frequently used food contact surfaces in household settings, including plastic cutting board (CB), formica laminate (LA), and stainless steel (SS) surfaces. S. Typhimurium at log (6 h), stationary (24 h), or long-term stationary (LTS) (14 days) phases were evaluated. Results showed that, at medium and high microbial loads, LTS phase cells had significantly higher survivor population compared to log and stationary phase cells at 24 h after inoculation (p < 0.05). Disinfection study showed that LTS phase cells were very resilient to sodium hypochlorite when the initial microbial load was high with disinfection efficacy ranging from 26 to 35%. Scanning electron microscopy of these surfaces at 24 h after inoculation with a high microbial load revealed an early biofilm structure.
Oil Preference In Ants And Arthropod Diversity In Urban Environments, Itzel Guzman-Hernandez
Oil Preference In Ants And Arthropod Diversity In Urban Environments, Itzel Guzman-Hernandez
Honors Theses
The success of certain ant species in urban areas is largely unknown. Available food in the environment could affect the composition of ants in urban areas due to a possible relationship between ant physiology and diet. I tested the oil preference of ants as a function of available arthropod prey in urban environments. I hypothesized that as arthropod diversity decreased, ant abundance at oil baits would decrease. Oil is an important nutrient that can affect ant body functions and activities. Ant foraging activities have been found to be affected by lipid depletion. A food source where ants can obtain oil …
Challenges Of Underserved Students In Disadvantaged Schools: Influence Of Training On School Counselors’ Self-Efficacy, Latonya Lovet Bunch
Challenges Of Underserved Students In Disadvantaged Schools: Influence Of Training On School Counselors’ Self-Efficacy, Latonya Lovet Bunch
Doctoral Dissertations and Projects
A child’s social, mental, and emotional well-being is significant to his/her daily functioning and academic achievement. Socioeconomic impoverished students are often burdened by traumatic experiences and stressors from their homes, communities, and school environment that can exacerbate academic difficulties. Schools in low socio-economic status (SES) communities are frequently coupled with educational disadvantages. Consequently, the lack of expectations, resources, training, and qualified staff often characterizes schools in these communities. For these reasons, these challenges require additional development of school counselors’ capabilities. To serve all students, it is important for practicing school counselors to increase their awareness of the specific needs to …

An Evidence-Based Intervention To Reduce The Use Of Physical Restraints In A Female Adolescent Population At An Inpatient Psychiatric Unit, Mambo Ndingwan
An Evidence-Based Intervention To Reduce The Use Of Physical Restraints In A Female Adolescent Population At An Inpatient Psychiatric Unit, Mambo Ndingwan
Doctor of Nursing Practice
The use of physical restraints within psychiatric units is problematic since it raises a range of legal, ethical, and clinical questions (American Psychiatric Nurses Association, 2014). The use of physical restraint has become a common practice in many psychiatric units despite the negative effects associated with its use. Selecting strategies such as verbal de-escalation to manage aggressive psychiatric inpatients shows promise with patients when used by providers and staff in mental health facilities. The purpose of this evidence-based project was to introduce and train staff to utilize the Modified Overt Aggression Scale (MOAS) and verbal de-escalation in psychiatric units in …
Anxiety Symptoms As A Predictor Of Head And Neck Cancer Survival And Potential For Mediation By Cancer Treatment Response., Tyler D. Pollitt
Anxiety Symptoms As A Predictor Of Head And Neck Cancer Survival And Potential For Mediation By Cancer Treatment Response., Tyler D. Pollitt
College of Arts & Sciences Senior Theses
BACKGROUND:
Head and neck cancers (HNC) are associated with high rates of depression, which seems to affect overall survival. However, little attention has been paid to the effects of anxiety on overall survival, though anxiety has been shown to activate inflammatory pathways implicated in cancer symptom development and progression. Here it was hypothesized that higher pre-treatment anxiety levels in HNC patients would predict poorer overall two-year survival and a higher likelihood of subsequent HNC treatment failure. Additionally, we expected that the relationship between higher pre-treatment anxiety and poorer two-year overall survival would be mediated by treatment failure.
METHODS:
Patients (n …
Effects Of Different Water And Nitrogen Regimens On Yield Of Winter Wheat Produced In Nebraska, Joseph Emory Davis
Effects Of Different Water And Nitrogen Regimens On Yield Of Winter Wheat Produced In Nebraska, Joseph Emory Davis
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Wheat is the 3rd most prominent crop in the United States and approximately 50% is exported annually. Nebraska wheat production is 11th in the country, and it plays a major role in the state's agricultural economy, especially in western Nebraska. Generally, wheat is grown under dryland conditions and the region grows much more wheat on unirrigated land than it does on irrigated. However, deficit irrigation has shown great value in producing high yielding wheat with much less water than needed for other crops. Finding new ways to leverage irrigation in wheat production may help address the need to produce …
A Survey Of Soil Properties Affecting Vegetation Establishment Along Nebraska Highways, Shad D. Mills
A Survey Of Soil Properties Affecting Vegetation Establishment Along Nebraska Highways, Shad D. Mills
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Vegetation along roadsides is important to prevent soil erosion, provide habitat and filter water running off the road. Along some highways in Nebraska vegetation does not readily establish and persist. It is thought that sodium and bulk density issues are the driving factor behind the lack of vegetation. After a construction project, the shoulder is seeded into the compacted soil, and salts can accumulate in the soil due to deicing agents being used during the winter. The purpose of our study was to determine if the bulk density and sodium are the driving factors of the vegetation cover. We also …
Use Of Uav Imagery And Nutrient Analyses For Estimation Of The Spatial And Temporal Contributions Of Cattle Dung To Nutrient Cycling In Grazed Ecosystems, Amanda E. Shine
Use Of Uav Imagery And Nutrient Analyses For Estimation Of The Spatial And Temporal Contributions Of Cattle Dung To Nutrient Cycling In Grazed Ecosystems, Amanda E. Shine
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Nutrient inputs from cattle dung are crucial drivers of nutrient cycling processes in grazed ecosystems. These inputs are important both spatially and temporally and are affected by variables such as grazing strategy, water location, and the nutritional profile of forage being grazed. Past research has attempted to map dung deposition patterns in order to more accurately estimate nutrient input, but the large spatial extent of a typical pasture and the tedious nature of identifying and mapping individual dung pats has prohibited the development of a time- and cost-effective methodology. The first objective of this research was to develop and validate …
Mammalian Artificial Chromosomes As A Synthetic Biology Tool For Transgene Expression, Charles Wang
Mammalian Artificial Chromosomes As A Synthetic Biology Tool For Transgene Expression, Charles Wang
All Theses
Mammalian artificial chromosomes, or MACs, have been studied as a potential avenue for hosting large numbers of transgenes in mammalian cells. MACs have several advantages over viral-based methods for transgene expression, including a lack of limits on loading capacity, which bypasses issues associated with integration into the genome. One area of research in which MACs can be applied is the biomanufacturing of protein-based therapeutics, where reported genome instability in Chinese hamster ovary (CHO) cells can lead to reduced product titer. MACs can potentially aid in solving this issue by providing alternate hosting sites for transgenes for integration of protein-based therapeutic …
Evaluation Of A Proprietary Slow-Release Oxytocin Therapy And Return Of The Luteolytic Mechanism In Mares, Brendan Andrew Sarnecky
Evaluation Of A Proprietary Slow-Release Oxytocin Therapy And Return Of The Luteolytic Mechanism In Mares, Brendan Andrew Sarnecky
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Prolonging function of the corpus luteum (CL) is a method of suppressing estrus that maintains secretion of endogenous progesterone to keep mares out of heat naturally. The use of oxytocin to prolong CL function is becoming more popular. In these therapies, upregulation of cyclooxygenase-2 is inhibited, which impairs prostaglandin F2α ( PGF2α) production. Intramuscular (IM) administration of 60 IU of oxytocin once daily from 7 to 14 days after ovulation is currently the most common treatment protocol. Although that protocol is efficacious in ≥70% of treated mares, the need for daily administration is a drawback to its use. A proprietary …

Towards The Synthesis Of An Artificial Fluorescent Siderophore, Ashley Burns
Towards The Synthesis Of An Artificial Fluorescent Siderophore, Ashley Burns
Honors Theses
Siderophores are molecules capable of binding ferric ions with high affinity (Ka = 1052). This thesis outlines our attempts to synthesize an artificial siderophore, which incorporates a signaling group to help monitor the uptake of ferric ions. The artificial siderophore is a tripodal molecular receptor synthesized in a five-step procedure with a proposed final sixth step. Rhodamine 6G azide (95.0% yield) was formed from rhodamine 6G and the synthesis of 2-azidoethanamine was modified from the literature. The tripodal arm portion of the sensor was successfully synthesized by protecting the catechol of 2,3-dihydroxybenzaldehyde to form 3-formyl-1,2-phenylene dimethanesulfonate (98.8% yield). The reduction …
An Evaluation Of Hybrid Traits, Yield, And Major Qtl Effect On Heterosis In Hybrid Soft Red Winter Wheat, Zachary James Winn
An Evaluation Of Hybrid Traits, Yield, And Major Qtl Effect On Heterosis In Hybrid Soft Red Winter Wheat, Zachary James Winn
Graduate Theses and Dissertations
Wheat (Triticum aestivum L.) is a self-pollinating species that is most often bred as a recombinant inbred line. When two inbred individuals are crossed, they produce progeny which experience heterosis; heterosis is the increased robustness experienced due to the reintroduction of heterozygosity. Hybrid wheat may be produced through the use of chemical hybridization agents, yet the structure of wheat flowers decreases the efficiency of outcrossing. The objectives of this study were to: assess the amount of heterosis experienced by a population of hybrid wheat and observe the effect of major gene loci on yield and yield components, phenotype anthers extruded …

Investigating Egg Storage Conditions, Hatch Characteristics, And Feeding Methods Of Commercially Produced Poultry, Joshua R. Deines
Graduate Theses and Dissertations
Advancements in poultry research continue to add knowledge and understanding to an already technical industry. Such information has led to new developments in early feeding strategies which provide nutrients to broiler chicks while in the egg or during transport. This wealth of knowledge in poultry research extends beyond chickens and is utilized for other species, such as quail and pheasants, including how fertile eggs are stored and incubated. However, methods of early feeding broilers have not been investigated in industry relevant approaches to understand its effects, including how timing of feed access interacts with the hatch window. As well, quail …

Strategies To Improve Forage Utilization By Sheep Offered Forage Mixtures, Valens Niyigena
Graduate Theses and Dissertations
In the first experiment, alfalfa and novel endophyte-infected tall fescue (NE+) forages were harvested after a killing frost, then mixed to formulate 4 different treatments; alfalfa alone, 67% alfalfa +33% fescue, 33% alfalfa + 67% fescue, or 100% fescue. After 3 months of storage as silage, Dorper ewe lambs (n = 20; mean BW = 34.7 ± 6.65 kg) were fed silage for ad libitum consumption, using 5 animals per treatment. Increasing the proportion of NE+ tall fescue improved (P < 0.05) silage total acids and lactic acid concentrations and decreased silage ammonia concentration. Digestible dry matter and organic matter intake and nitrogen utilization parameters decreased with increasing inclusion of NE+ in diet. In the second experiment, 16 Dorper ewe lambs (41.8 ± 4.61 kg BW) were assigned to 4 different treatments; alfalfa silage alone (0 g/kg; CONT) or alfalfa silage mixed with chopped sericea lespedeza (SL) hay to provide 90 (LOW), 180 (MED), or 270 g/kg SL (HIGH) on a dry matter basis in a randomized complete block design experiment with 2 period to provide 4 observations per treatment for each experimental period. Increasing the proportion of sericea lespedeza in the diet decreased dry matter and organic matter digestibility but did not affect feed intake. Fecal nitrogen (g/kg N intake) increased linearly (P < 0.01) while urinary N (g/ day and g/ kg of N intake) tended to decreased linearly and quadratically (P ≤ 0.1) with increasing the proportion of SL in diet. In the third experiments, 16 gestating Dorper ewe lambs (49.1 ± 4.61 kg BW) were allocated to 4 treatments; alfalfa silage alone (0% g/kg; CONT) or alfalfa silage mixed with lablab purpureus(LP) hay to provide 90 (LOW), 180 (MED), or 270 g/kg LP (HIGH) on a dry matter (DM) basis, in a randomized complete block design experiment with a total 8 replication per treatment. Supplementation of LP in diet increased quadratically (P ≤ 0.04) forage dry matter, organic matter intake, digestible dry matter and digestible organic matter intake (P < 0.05). Nitrogen apparently absorbed and urinary N both decreased linearly (P < 0.01) with adding more LP hay in diet. Harvesting and mixing alfalfa and fescue after a killing frost improved silage fermentation characteristics and supplementation of tannins from SL and polyphenol from LP altered N excretion.
Key words: lablab, sericea lespedeza, alfalfa silage, nitrogen, sheep.

Curing Consumption: Blood Drinkers Of The Nineteenth Century, Rachel Erin Catlett Widmer
Curing Consumption: Blood Drinkers Of The Nineteenth Century, Rachel Erin Catlett Widmer
Graduate Theses and Dissertations
During the nineteenth century burgeoning cities in the United States saw the spread of disease. Most common among all parts of society was tuberculosis or as it was commonly known at the time, consumption. The most terrifying aspect of consumption was that it could attack anyone at any time and no cure existed. The poetic image of a red stained handkerchief was a death sentence. The common cure was to seek fresh air in a warmer climate. However, for some Americans an experimental cure seemed hopeful and easily accessible, drinking blood. According to many newspaper accounts consumptive victims were not …
