The Impact Of Plant Cell Wall Lignin On Energy Utilization In Lactating Jersey Cows, Jason D. Stypinski

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

Fiber from forages comprises a significant proportion of dairy cattle rations and by extension, it contributes largely to the energy concentration of the diet. While the proportion of fiber in the diet is important, the composition of fiber is probably more important as the different constituents of this fraction vary in their contributions to the nutritive value of the feed. Lignin has been described as an important factor limiting the digestion of NDF, reducing intake, and compromising milk production. Although lignin’s effects on these responses have been well characterized, the literature lacks data on the use of indirect calorimetry to …

Microbiome Variation Across Populations Of Desert Halophyte Zygophyllum Qatarensis, Abdul Latif Khan, Lucas Dantas Lopes, Saqib Bilal, Sajjad Asaf, Kerri M. Crawford, Venkatesh Balan, Ahmed Al-Rawahi, Ahmed Al-Harrasi, Daniel P. Schachtman

Department of Agronomy and Horticulture: Faculty Publications

Microbial symbionts play a significant role in plant health and stress tolerance. However, few studies exist that address rare species of core-microbiome function during abiotic stress. In the current study, we compared the microbiome composition of succulent dwarf shrub halophyte Zygophyllum qatarensis Hadidi across desert populations. The results showed that rhizospheric and endosphere microbiome greatly varied due to soil texture (sandy and gravel). No specific bacterial amplicon sequence variants were observed in the core-microbiome of bulk soil and rhizosphere, however, bacterial genus Alcaligenes and fungal genus Acidea were abundantly distributed across root and shoot endospheres. We also analyzed major nutrients …

Department of Electrical and Computer Engineering: Faculty Publications

Due to its role in maintaining the proper functioning of the cell, the pentose phosphate pathway (PPP) is one of the most important metabolic pathways. It is responsible for regulating the concentration of simple sugars and provides precursors for the synthesis of amino acids and nucleotides. In addition, it plays a critical role in maintaining an adequate level of NADPH, which is necessary for the cell to fight oxidative stress. These reasons prompted the authors to develop a computational model, based on queueing theory, capable of simulating changes in PPP metabolites’ concentrations. The model has been validated with empirical data …

Livestock Performance In Response To High Intensity Rotational Grazing System, Austin Kennedy

Honors Program: Senior Projects (Public)

The production of livestock is composed of a variety of factors all effecting the outcome. For grazing livestock, a key factor in production is the grazing management system. Two of the most common grazing management systems are continuous grazing and rotational grazing. There has been evidence found proving benefits of rotational grazing in regard to vegetation productivity, and prevention and restoration of degraded rangeland. However, there is a lack of clear evidence on the relationship between grazing system and production metrics of livestock. Understanding this relationship can provide the necessary information for livestock producers in order to increase their production …

Greater Numbers Of Antral Follicles In The Ovary Are Associated With Increased Concentrations Of Glucose In Uterine Luminal Fluid Of Beef Heifers, Alexandria P. Snider, Matthew S. Crouse, Shelby L. Rosasco, Kaitlin M. Epperson, Emmalee J. Northrop-Albrecht, Jerica J.J. Rich, Chadwick C. Chase Jr., Jeremy R. Miles, George A. Perry, Adam F. Summers, Robert A. Cushman

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Increased antral follicles are associated with greater fertility and a uterine environment that is more supportive of early embryonic development in beef heifers. Glucose is a primary energy source for embryos, and glucose concentrations are elevated in uterine luminal fluid (ULF) of pregnant heifers. We hypothesized that ULF glucose concentrations and endometrial transcript abundance for glucose transporters on d16 after insemination would be greater in heifers with increased numbers of antral follicles. Heifers classified with either increased or diminished antral follicle counts were artificially inseminated following the CO-Synch protocol (d0). On d16 after insemination, reproductive tracts of heifers were collected …

Creation Of An Influenza A Virus Neuraminidase Consensus Vaccine In An Adenoviral Vector, Leigh Jahnke

Honors Program: Senior Projects (Public)

In the last decade, the estimated annual burden of the flu includes 12,000-52,000 deaths, 140,000-710,000 hospitalizations, and 9 million – 41 million illnesses (Centers for Disease Control and Prevention: Disease burden of the flu). Influenza A virus can mutate and infect a variety of different hosts, which results in frequent antigenic changes and even pandemics. This has led to increased attention on the creation of a universal Influenza A vaccine containing broader immunogenic coverage than current vaccines. Our research involved detailing the steps of the cloning process utilizing a consensus neuraminidase antigen. We utilized the pAdEasy Adenoviral Vector …

Reduction Of Stabilin-2 Contributes To A Protection Against Atherosclerosisstabilin, Yukako Kayashima1*,, Conner A. Clanton, Amanda M. Lewis, Xinghui Sun, Sylvia Hiller, Phillip Huynh, Jennifer Wilder, John Hagaman, Feng Li, Nobuyo Maeda-Smithies, Edward N. Harris

Department of Biochemistry: Faculty Publications

We have previously identified a novel atherosclerosis quantitative trait locus (QTL), Arch atherosclerosis 5 (Aath5), on mouse chromosome 10 by three-way QTL analyses between Apoe^−/− mice on a DBA/2J, 129S6 and C57BL/6J background. The DBA/2J haplotype at the Aath5 locus was associated with smaller plaque size. One of the candidate genes underlying Aath5 was Stabilin-2 (Stab2), which encodes a clearance receptor for hyaluronan (HA) predominantly expressed in liver sinusoidal endothelial cells (LSECs). However, the role of Stab2 in atherosclerosis is unknown. A congenic line of Apoe^−/− mice carrying Aath5 covering the Stab2^DBA allele …

Determining Pairwise Interactions To Predict Species Interactions In A Complex Community Of Gut Bacteria., Makenzie Maroney

Honors Program: Senior Projects (Public)

The human gastrointestinal (GI) tract houses a diverse and expansive microbial community known as the microbiota. The relationship between the host and the microbiota is considered to be mutualistic, as trillions of bacteria that reside in the hospitable GI tract can assist in essential host functions, including contributing to metabolism and immunity against disease. An important subpopulation of the GI microbiota is the mucin-associated biofilm that is comprised of a dense layer of bacteria that forms on the GI mucin layer. The mucin layer provides an alternative niche to the GI lumen; the glycans of the mucin and the subsequent …

Starvation Diets: The History And Moral Implications Of Prolonging The Lives Of Juvenile Diabetics Before The Discovery Of Insulin, Olivia Thompson

Honors Program: Senior Projects (Public)

This study explores the state of diabetology before Frederick Banting’s discovery of insulin in 1921, when juvenile diabetes was a terminal diagnosis. The widespread misunderstanding of the disease at the hands of physicians and scientists culminated in improper treatments and erroneous anatomical literature about diabetes until the age of discovery in the late 19th and early 20th centuries. More extensively, I examine the controversial work of 20th-century physician Frederick Madison Allen, who attempted to prolong the lives of juvenile diabetics by subjecting them to a rigid starvation diet by way of experimental trials lasting from 1915 to 1922. This diet …

The Importance Of Nutrition In Oral Health In The General Population And Among Children And Adolescents, Emma Barnes

Honors Program: Senior Projects (Public)

Having good oral health is vital for the U.S. population. Although there have been improvements, too many suffer from dental caries and tooth loss. Providing education, dental procedures, and nutritional foods can help prevent these issues. Healthy choices include having a diet with adequate protein, vitamin A, vitamin C, and the vitamin B complex to support proper tissue development in the oral cavity.

Keeping good oral health is crucial for those suffering from diabetes mellitus. Studies show that doing this can help lower the patient's A1C, therefore helping with the management of blood glucose levels and potentially slowing the progression …

School of Natural Resources: Faculty Publications

White‐tailed deer (Odocoileus virginianus) and hunters on 2 Wildlife Management Areas (WMAs) within the Chattahoochee National Forest of northern Georgia, USA, significantly declined in number from the 1980s to 2018. Managers were interested in understanding how they could manipulate hunter distribution according to deer management goals. To understand the spatial distribution of hunting pressure and factors driving hunter resource selection, we analyzed GPS tracking data from 58 deer hunters over the 2018–2019 and 2019–2020 hunting seasons. We evaluated hunter selection on 3 spatial scales relative to elevation, slope, and distance from roads, trails, wildlife openings, deciduous forest, mixed …

An Overlooked Epidemic: Pediatric Oral Health Concerns On The Rise In Rural Communities, Emma Verbrugge

Honors Program: Senior Projects (Public)

Pediatric oral health is a concern for many dentists and parents as they lay the foundation for long-term proper hygiene in children. Early childhood caries (ECC) is a disease of chronic tooth decay marked as the most common chronic disease of childhood in the world. Children living in rural areas are even more susceptible to this disease and thus significant attention is needed to curve these numbers. The consequences of ECC are much more than just cosmetic, but include heightened risk of gingivitis, periodontal disease, diabetes, cardiovascular disease, and much more. A foundational cause of poor dental hygiene lies with …

The cotyledon and caruncle tissues provide a functional bridge between the fetus and the dam. However, the relationship between these tissues and the transcriptomic profile that underlies the tissue functions remains elusive. Herein we investigate the expression profile of cotyledon and caruncle from nulliparous beef heifers carrying female fetuses at day 83 of pregnancy to identify changes occurring across tissues that contribute to placental function and their tissue-specific roles. We identified 2654 differentially expressed genes [padj ≤ 0.05, abs(log2FC) ≥ 1], including nutrient transporters and paternally imprinted genes. We found key regulators of tissue function and differentiation, including FOXO4, GATA2, …

Assessing Pre-Literacy Behaviors In Infants And Toddlers: Psychometric Evaluation Of The Infant Toddler Literacy Assessment (Itla-3), Barbara J. Jackson, Christine Marvin, Amy J. Encinger, Nicole Buchholz, Becky Zessin

Department of Special Education and Communication Disorders: Faculty Publications

Assessment of emerging literacy in young children is generally limited to either skill development in children over 3 years of age or the quality and context of young children’s early literacy experiences. Although there has been promotion of their early literacy experiences, assessment of emerging pre-literacy behaviors in children younger than 3 years has yet to be organized into a single tool.

Preliminary work on the Infant Toddler Literacy Assessment (ITLA) has progressed through initial steps of scale development and shown promise as a criterionbased, standardized assessment for tracking children’s pre-literacy behaviors and guiding practitioners in supporting development of those …
