Age-Related Oligodendrocyte Lineage And Learning Abnormalities Driven By Nf1 Mutation In Mice, Saul Lopez

Theses and Dissertations

Neurofibromatosis Type 1 (NF1) is an autosomal dominant disease caused by mutations in the NF1 gene, on chromosome 17. NF1 patients suffer from a number of neurological issues including learning deficits and increased risk of age-related dementia. Additionally, NF1 patients present with multiple white matter and myelin abnormalities. Whether and how myelin abnormalities impact learning in NF1 is not known; therefore, we aimed to gain insights on potential links between Nf1 mutation and learning issues Unpublished data indicate that NF1 female-but not male- mice with Nf1+/- germline mutation show defects in a myelin-regulated learning/memory test (the complex wheel; CW) at …

Forages And Technology Management In Growing And Finishing Beef Cattle Systems, Kelton Cole Adair

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

A systems study evaluated the effects of an implant [25.7 mg estradiol (Compudose; Elanco Animal Health)] at two rates of gain (LOW: 0.45 kg/d and HIGH: 0.9 kg/d) applied during the winter backgrounding phase in drylot and winter grazing systems and its effects on subsequent phases of production. HIGH supplementation with an implant during the winter backgrounding phase in the drylot system yielded the greatest ending body weight (EBW) during the summer backgrounding phase (P = 0.04). LOW supplementation, without an implant, improved summer backgrounding average daily gain (ADG; P = 0.05) while achieving similar carcass adjusted final body …

Factors Affecting Forage Quality And The Subsequent Response In Production And Energy Metabolism In Lactating Jersey Cows, Kassidy Kate Buse

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

Forage quality is the potential of a forage to produce a production response in animals. Because of how essential they are in dairy cattle rations, forages can have major influence on the behavior and production of dairy cattle. In experiment 1, the effect of forage fragility on the rumen environment and digestibility was evaluated. Increasing the inclusion of a less fragile forage led to greater rumen retention time, which resulted in lower rumen pH and greater NDF digestibility. Experiment 2 evaluated the effects of diets high in either corn silage or alfalfa haylage supplemented with either corn- or soybased protein …

Early-Life Supplementation Of Omega-3 Polyunsaturated Fatty Acids Improved Growth And Skeletal Muscle Glucose Metabolism In The Heat Stress-Induced Iugr Neonatal Lamb, Melanie Ryann White

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

Our 1^st study determined whether metabolic deficits of IUGR-born neonatal lambs can be improved by ameliorating elevated inflammatory tone. Supplementation with ω-3 polyunsaturated fatty acids (ω-3 PUFA) improved hindlimb insulin-stimulated glucose oxidation rates and basal lactate secretion. Ex vivo skeletal muscle-specific glucose oxidation rates were improved when heightened inflammatory tone was moderated. Pancreatic β cell function in response to hyperglycemia was improved by ω-3 PUFA supplementation. Tempered inflammatory tone also partially recovered skeletal muscle glycogen stores. Thus, we found that targeting heightened inflammatory tone inherent in IUGR-born neonatal lambs moderately improved glucose metabolism and pancreatic β cell …

Owuor, Victor Akelo, Florence Murila, Dickens Onyango, Magdalene Kuria, Emily Rogena, Gunturu Revathi, Paul Mitei, Solomon Sava, Joyce Were

Pathology, East Africa

Objectives: To describe RDS in neonatal deaths at the CHAMPS-Kenya site between 2017 and 2021.

Methods: We included 165 neonatal deaths whose their Causes of death (COD) were determined by a panel of experts using data from post-mortem conducted through minimally invasive tissue specimen testing, clinical records, and verbal autopsy.

Results: Twenty-six percent (43/165) of neonatal deaths were attributable to RDS. Most cases occurred in low birthweight and preterm neonates. From these cases, less than half of the hospitalizations were diagnosed with RDS before death, and essential diagnostic tests were not performed in most cases. Most cases received suboptimal levels …

Microbiota Dynamics, Metabolic And Immune Interactions In The Cervicovaginal Environment And Their Role In Spontaneous Preterm Birth, Stanely Onyango, Jia Dai Mi, Anjela Koech, Patricia Okiro, Marleen Temmerman, Peter Von Dadelszen, Rachel Marie Tribe, Geoffrey Omuse

Pathology, East Africa

Differences in the cervicovaginal microbiota are associated with spontaneous preterm birth (sPTB), a significant cause of infant morbidity and mortality. Although establishing a direct causal link between cervicovaginal microbiota and sPTB remains challenging, recent advancements in sequencing technologies have facilitated the identification of microbial markers potentially linked to sPTB. Despite variations in findings, a recurring observation suggests that sPTB is associated with a more diverse and less stable vaginal microbiota across pregnancy trimesters. It is hypothesized that sPTB risk is likely to be modified via an intricate host-microbe interactions rather than due to the presence of a single microbial taxon …

A Comparison Of The Academic Performance Of Third-Fifth Grade Students In A Title I School Using Virtual Versus Face-To-Face Instruction, Shalyn Valencia Clay

Dissertations (2016-Present)

The Center for Disease Control (CDC) did not allow elementary aged students to receive the vaccination for COVID-19 (which will be referred to as the pandemic) until the Spring of 2021. This created two environments: the face-to-face learning environment and the virtual learning environment. Teachers were thrown into a situation in which they had to consider the risks to their own health before deciding on the best way to teach a particular lesson. Virtual learning was not considered by some to be as effective as face-to-face learning. The purpose of this quantitative comparative study was to analyze the mean scores …

The Connection Between Correlational Control Rate And Successful Probation Discharge Rates In The United States, Myron Syvelle Hopes

Dissertations (2016-Present)

This dissertation analyzes the connection between correctional rates and probation rates to find the harshness of a state’s correctional program that evaluates the successful completion of probation. The answer starts with correctional control conversion to a score assigned to each state and compared against their successful probation completion rate. The correctional control rates are the total number of persons within a state’s correctional system and from the Prison Policy Initiative. The study will employ Social Control Theory as the underlying theoretical framework in examining the harshness of correctional control rates as it relates to successful probation outcomes.

Private Continuous Survival Analysis With Distributed Multi-Site Data, Luca Bonomi, Marilyn Lionts, Liyue Fan

Faculty, Staff and Student Publications

Effective disease surveillance systems require large-scale epidemiological data to improve health outcomes and quality of care for the general population. As data may be limited within a single site, multi-site data (e.g., from a number of local/regional health systems) need to be considered. Leveraging distributed data across multiple sites for epidemiological analysis poses significant challenges. Due to the sensitive nature of epidemiological data, it is imperative to design distributed solutions that provide strong privacy protections. Current privacy solutions often assume a central site, which is responsible for aggregating the distributed data and applying privacy protection before sharing the results (e.g., …

Fair Canonical Correlation Analysis, Zhuoping Zhou, Davoud Ataee Tarzanagh, Bojian Hou, Boning Tong, Jia Xu, Yanbo Feng, Qi Long, Li Shen

Faculty, Staff and Student Publications

This paper investigates fairness and bias in Canonical Correlation Analysis (CCA), a widely used statistical technique for examining the relationship between two sets of variables. We present a framework that alleviates unfairness by minimizing the correlation disparity error associated with protected attributes. Our approach enables CCA to learn global projection matrices from all data points while ensuring that these matrices yield comparable correlation levels to group-specific projection matrices. Experimental evaluation on both synthetic and real-world datasets demonstrates the efficacy of our method in reducing correlation disparity error without compromising CCA accuracy.
