Kinetics Of Protein And Amino Acids, S. Y. Liu, M. Toghyani, S. P. Macelline, P. H. Selle Jan 2025

Kinetics Of Protein And Amino Acids, S. Y. Liu, M. Toghyani, S. P. Macelline, P. H. Selle

Proceedings of the Arkansas Nutrition Conference

Protein and amino acid nutrition is key to poultry growth and sustainability, with synchrony between glucose and amino acid availability being critical for efficient feed conversion. While non-bound amino acids (NBAA) are rapidly absorbed and increasingly used to reduce crude protein levels, their fast uptake may disrupt amino acid balance and reduce nutrient utilization compared to protein-bound amino acids. Future research should redefine amino acid requirements in low-CP diets, explore the metabolic fate of NBAA, and investigate how protein sources affect gut microbiota and host metabolism.


Low Protein Diet Strategy, S. Y. Liu, P. V. Chrystal, M. T. Kidd, M. Toghyani, S. P. Macelline, P. H. Selle Jan 2025

Low Protein Diet Strategy, S. Y. Liu, P. V. Chrystal, M. T. Kidd, M. Toghyani, S. P. Macelline, P. H. Selle

Proceedings of the Arkansas Nutrition Conference

Reduced crude protein (CP) diets can lower nitrogen excretion and improve litter quality, but their effectiveness varies depending on the grain type, with wheat-based diets often showing poorer broiler performance compared to maize or sorghum. The digestive dynamics and synchrony between NBAA and protein-bound amino acids, along with starch-to-protein ratios, influence feed efficiency and fat deposition, which remains a challenge in reduced CP diets. Optimizing amino acid supplementation and exploring alternative protein-rich ingredients may help improve outcomes, especially in regions with limited access to soybean meal.

An Investigation Into How The Prostate And Androgens Mediate Greater Levels Of Uric Acid In Males Compared To Females, Rachel D. King Jan 2025

An Investigation Into How The Prostate And Androgens Mediate Greater Levels Of Uric Acid In Males Compared To Females, Rachel D. King

Graduate Theses, Dissertations, and Problem Reports (ETD)

Chronic elevated circulating uric acid (UA) levels (hyperuricemia) are associated with gout as well as cardiovascular, metabolic, and renal dysfunction. Men have greater mean circulating UA levels than women and are more likely to exhibit hyperuricemia. This may be partly driven by the hormonal regulation of renal UA transporters; however, a direct link between hormones and UA production has not been established. Production of UA is catalyzed by xanthine oxidoreductase (XOR / XDH), which is ubiquitously expressed but has the greatest specific activity in the liver. Interestingly, an extensive gout genome-wide association study (GWAS) recently revealed a robust genetic …

Genomic Differences And Parentage In West Virginia's Reintroduced Elk (Cervus Canadensis), Adam A.V. Cook

Graduate Theses, Dissertations, and Problem Reports (ETD)

Elk (Cervus canadensis) reintroductions have been common in the 20th and 21st centuries, yet 40% have failed to establish self-sustaining elk populations due to a lack of post-reintroduction demographic monitoring. Elk were reintroduced to West Virginia in 2016 following more than a century of absence after the species was extirpated in 1875. Elk were translocated to West Virginia from Land Between the Lakes National Recreation Area (LBL) in eastern Kentucky and from Arizona. The two groups of elk differ in their subspecies, physiology, reintroduction history, connectivity, and habitat. Reintroductions create genetic risks such as the founder effect and …


Raman Spectroscopy For Rapid Quantification Of Macronutrients In Heirloom Beans, K. Chandler Williams Jan 2025

Raman Spectroscopy For Rapid Quantification Of Macronutrients In Heirloom Beans, K. Chandler Williams

Graduate Theses, Dissertations, and Problem Reports (ETD)

Quantification of macronutrients in food requires a large investment in facilities and instrumentation as well as ongoing expenses of labor, reagents, and hazardous waste disposal. These costs pose a significant barrier to determining macronutrient quantities in the thousands of uncharacterized landrace and heirloom crops and discourage traditional crop breeding projects from ensuring that their selected crops maintain desirable macronutrient profiles in addition to target agronomic traits. Our objective was to test whether a hand-held Raman spectrometer—a technology which has found use in plant disease diagnostics but remains largely overlooked in nutrient quantification-- could provide a feasible means for quantifying the …

New Genetic Tools To Define The Pathophysiology Of Inborn Errors Of Cobalamin Metabolism Impacting Mammalian Development, Tiffany Chern, Xuefei Tong, William G Bauer, David J Quispe-Parra, Xia Gao, Kamryn N Gerner-Mauro, Ross A Poché

Children’s Nutrition Research Center Staff Publications

The congenital, autosomal recessive disorder combined methylmalonic acidemia and homocystinuria - cblC type, is the most common inborn error of cobalamin (vitamin B12) metabolism. In its early onset form, cblC profoundly impacts fetal development of the central nervous system, hematopoietic system, and other tissues. Previously, mutations in the MMACHC gene, which encodes a protein required for the intracellular trafficking and enzymatic processing of free cobalamin into active coenzyme forms, were found to cause cblC. These coenzymes are required in two metabolic pathways which produce either succinyl-CoA in the mitochondria or methionine in the cytosol. However, due to a lack of …

Neuroendocrine Regulation Of The Luteinizing Hormone Surge And Puberty Onset In Sheep, Max J. Griesgraber Jan 2025

Neuroendocrine Regulation Of The Luteinizing Hormone Surge And Puberty Onset In Sheep, Max J. Griesgraber

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH), and follicle stimulating hormone (FSH) are essential for the reproduction of all mammalian species, including both sheep and humans. GnRH is secreted by hypothalamic neurons into the hypophyseal portal vasculature in a pulsatile manner, which then acts within the anterior pituitary to elicit the release of LH and FSH into wider systemic circulation. In females LH and FSH act on the ovaries to promote estradiol (E2) production, follicular development, and under certain conditions in regard to LH, ovulation. Furthermore, while E2 inhibits GnRH and subsequent LH secretion under most conditions, at high concentrations E2 …


Molecular Characterization Of Fungus-Arthropod Associations, Angie M. Martin Jan 2025

Molecular Characterization Of Fungus-Arthropod Associations, Angie M. Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Arthropods, or phylum Arthropoda, are the largest group of animals, accounting for over three quarters of all animal records on NCBI Taxonomy. And yet, only 40% of all deposited sequences on NCBI Nucleotide come from arthropods. Clearly, arthropods are an understudied group of animals: they are small, often drab, and lead lives very alien to our own. Arthropods have chitinous exoskeletons, segmented bodies, and jointed appendages, and include crabs, barnacles, insects, spiders, and millipedes. Since the era of DNA based studies took off in the 1980s, DNA and other small molecules have been integral to our understanding of the Earth …
