Impacts Of Banamine Injection On Pain Responses Of Either Rubber Ring Castrated And Tail Docked Or Surgically Castrated And Docked Lambs, Paige Porter Anderson
Animal Sciences
Our hypothesis was that administering Flunixin Meglumine (FM) to lambs that were both rubber ring castrated and docked or surgically castrated and emasculator docked would decrease behavioral stress, serum cortisol, haptoglobin concentration, and wound and swelling score, but increase average daily gain. Rambouillet ram lambs (n = 181) were allocated with a completely randomized design in a 2 x 2 factorial arrangement of treatments. Treatment combinations included rubber ring castration and docking (on ram lambs with administration of saline or FM) or surgical castration and emasculator docking (on ram lambs with administration of saline or FM). Ram lambs were castrated …

Greenhouse and microplot studies were conducted for understanding the effects of cover crop species/cultivars for hosts and population reduction of soybean cyst nematode (SCN; Heterodera glycines) from the fields of North Dakota. Moreover, early-maturing soybean [Glycine max (L.)] accessions from different countries of origin were screened for resistance against two common SCN populations for finding new sources of resistance. Thirty-eight cover crop species/cultivars were evaluated for their hosting ability of two SCN populations (SCN103 and SCN2W) from two fields of North Dakota in greenhouse experiments. The majority of the tested crops were non-hosts for both SCN populations. However, a few …
The Molecular Basis Of Demethylation Inhibitor Fungicide Resistance In Cercospora Beticola And The Role Of Seed Inoculum In Cercospora Leaf Spot Disease Of Sugar Beet, Rebecca Ellen Spanner
The Molecular Basis Of Demethylation Inhibitor Fungicide Resistance In Cercospora Beticola And The Role Of Seed Inoculum In Cercospora Leaf Spot Disease Of Sugar Beet, Rebecca Ellen Spanner
Plant Sciences
Cercospora leaf spot (CLS) is the most destructive foliar disease of sugar beet worldwide. CLS is caused by the filamentous fungus Cercospora beticola. Disease management currently relies upon timely application of fungicides, but reliance on certain chemical classes has led to the development of resistance in multiple C. beticola populations. One such class is the demethylation inhibitor (DMI) fungicides of which the genetic basis of resistance has been unclear. Therefore, the first objective of this PhD research was to perform a genome-wide association study on 190 C. beticola isolates to identify mutations associated with tetraconazole (a common DMI) fungicide resistance. …
Comparative Study On Hulled Wheats Kernel, Flour, Dough Quality And Dietary Fiber Variation, Jayani Chathurika Sandarani Maddakandage Dona
Comparative Study On Hulled Wheats Kernel, Flour, Dough Quality And Dietary Fiber Variation, Jayani Chathurika Sandarani Maddakandage Dona
Plant Sciences
This study was conducted to evaluate the kernel, flour and dough qualities and dietary fiber content of hulled wheats. Experimental design was separate randomized complete block designs for hulled wheat species with four field replicates. According to the results, significant differences (p<0.05) were observed in kernel quality, flour, and dough quality compared to common bread wheat. Einkorn and spelt reported significantly lower insoluble dietary fiber and total dietary fiber content, in contrast emmer had contents with both higher and lower genotypes. Interestingly, few genotypes of hulled wheat had a higher content of low molecular weight soluble dietary fibers (LMW-SDF) such as fructo and galacto oligosaccharides. Overall, hulled wheats differed from modern bread wheat in their kernel, flour, baking and nutritional quality. Moreover, due to higher LMW-SDF content, hulled wheats would be a potential candidate for breeding and producing health beneficial novel food products.

Understanding Host Resistance And Pathogen Biology In The Wheat-Fusarium Graminearum Pathosystem, Bikash Poudel
Plant Sciences
Fusarium head blight (FHB) is a major challenge in global wheat production. In the United States, the disease is predominantly caused by the fungus Fusarium graminearum. Utilization of FHB-resistant wheat cultivars integrated with other measures such as fungicide application is the most effective approach for the management of this disease. This study aimed to 1) identify novel quantitative trait loci (QTL) for resistance to FHB in a Brazilian spring wheat cultivar ‘Surpresa’ through bi-parental mapping, 2) detect QTL for FHB resistance in a global panel of 233 spring wheat accessions by genome-wide association analysis (GWAS), and 3) localize genomic regions …
Multi-Parent Advanced Generation Inter-Cross Population For Improvement Of Genetic Resistance Of Dry Bean To White Mold, Edgar Gabriel Escobar Romero
Multi-Parent Advanced Generation Inter-Cross Population For Improvement Of Genetic Resistance Of Dry Bean To White Mold, Edgar Gabriel Escobar Romero
Plant Sciences
White mold (Sclerotinia sclerotiorum Lib. de Bary) is one of the most important diseases of common bean in the U.S. with seed yield losses up to 100%. White mold resistance is hard to incorporate into breeding materials because of low heritability, cumbersome screening methods, and few sources of resistance. A Multi-parent Advanced Generation Inter-Crosses population was created to develop resistant germplasm and map the genetics factors controlling the resistance. A seedling straw test method was used to identify resistant lines. Twenty genotypes were found to be resistant based on its response when inoculated with isolate 1980 of white mold. GWAS …

The Effect Of Salinity On Soil Microbial Community Structure, Mackenzie Lynn Ries
The Effect Of Salinity On Soil Microbial Community Structure, Mackenzie Lynn Ries
Soil Science
Soil salinity is a widespread problem that affects crop productivity. We expect that saline soils also have altered microbial community structure, soil food webs and related soil properties. To test this, we sampled field soils across four farms in eastern North Dakota that host salinity gradients. We evaluated microbial biomass carbon, phospholipid fatty acid analysis and nematode counts in moderately saline and low saline soils. Additionally, we measured soil properties that represent potential food sources and habitat characteristics that influence microbial communities. We found higher microbial group abundance in moderately saline soils than in the lower saline soils. In contrast, …

Childhood Obesity: Developing Early Nutrition & Feeding Education For Parents At Well Child Visits, Ashley Lynn Benson
Childhood Obesity: Developing Early Nutrition & Feeding Education For Parents At Well Child Visits, Ashley Lynn Benson
Nursing
Childhood obesity is an extensive problem in the United States and North Dakota (CDC, 2014). Significant health consequences are linked to obesity, including type two diabetes, hypertension, hyperlipidemia, cardiovascular disease, cancers, and psychological disorders (Pandita et al., 2016; Xu & Mishra, 2018). Obesity comorbidities, previously presented in later adulthood, now emerge in younger populations (Pandita et al., 2016). Unfortunately, treatment of obesity is not effective, and therefore, prevention must be the primary focus (Daniels et al., 2015; Pandita et al., 2016). Diet and eating behaviors have a significant impact on weight, and children develop taste preferences and lifelong eating behaviors …

A Collaborative Hypertension Clinic Pilot Program In A Rural Primary Care, Nicole Catherine Pink
Nursing
In 2019, there were about seventy-million Americans with uncontrolled high blood pressure (BP) or hypertension (HTN) (Kitt, Fox, Tucker & McManus, 2019). Hypertension is the leading cause of preventable deaths worldwide (Stephen, Halcomb, McInnes, Batterham & Zwar, 2019). Uncontrolled HTN contributes to stroke, myocardial infarction, and renal failure, and is the most modifiable risk factor for heart disease and death (American Academy of Family Physicians [AAFP], 2019; Oparil & Schmider, 2015). Patients living in rural America have an increased prevalence of HTN and their access to preventative health services is lower (Buford, 2016; Caldwell, Ford, Wallace, Wang & Takahashi, 2016). …

Identifying Barriers To Preventive/Primary Care Utilization Of Men In A Rural Setting, Shaun Earl Seibold
Nursing
The purpose of the project was to identify barriers preventing men living in a rural setting, ages 19-60 from participating in routine preventative/primary care. Nationally and globally, men experience greater rates of morbidity and mortality due to chronic illness (Xu, Murphy, Kochanek, Bastian, & Arius, 2018). The literature suggests men do not routinely engage in primary care services (Centers for Disease Control and Prevention [CDC], 2015). The lack of participation leads to men experiencing poorer health outcomes (Banks & Baker, 2013; Baker & Shand, 2017; Pinkashov et al., 2013). Consistent and early access to primary care will help reduce the …

Investigating The Role Of Becn1 Conformationally Flexible Regions And Invariant Cys-X-X-Cys Motifs In Autophagy, Shreya Mukhopadhyay
Investigating The Role Of Becn1 Conformationally Flexible Regions And Invariant Cys-X-X-Cys Motifs In Autophagy, Shreya Mukhopadhyay
Chemistry and Biochemistry
Autophagy is an essential catabolic cellular homeostasis process conserved in all eukaryotes. BECN1, a key autophagy protein involved in autophagosome nucleation, comprises of a large, poorly conserved, N-terminal intrinsically disordered region (IDR); a flexible helical domain; a coiled-coil domain (CCD) that forms anti-parallel homodimers in the absence of other interacting partners; and a β-α repeated autophagy specific domain (BARAD). The IDR of higher eukaryotes includes a BCL2 homology 3 domain (BH3D), which undergoes dramatic disorder-to-helix transitions upon binding to anti-apoptotic and anti-autophagic BCL2s. We show that the BH3D is not required for starvation-induced autophagy upregulation suggesting that BCL2-binding to the …
