Department of Pediatrics Faculty Papers
Spinal muscular atrophy (SMA) is characterized by degeneration of spinal motor neurons and is a leading genetic cause of pediatric death worldwide. SMA results from the loss of or pathological variant in the survival motor neuron 1 (SMN1) gene. Disease severity is dependent on the number of copies of the orthologous SMN2 gene, which is nearly identical to SMN1 except for some key nucleotide differences. As disease severity is inversely related to SMN2 copy number, most SMA therapeutics trials have focused on identifying ways to increase SMN2 expression at different levels of gene regulation. Other studies have investigated compounds which …

In this study, cold-pressed hemp seed oil, blended with a soybean carrier oil, is …
Integrated Analysis Of Untargeted Liver, Serum Metabolome And Gut Microbiome Following Selenium Deficiency Diet In Selenoh Knockout And Wildtype Mice, Richard Eugene Baird
Integrated Analysis Of Untargeted Liver, Serum Metabolome And Gut Microbiome Following Selenium Deficiency Diet In Selenoh Knockout And Wildtype Mice, Richard Eugene Baird
Theses and Dissertations
Selenoprotein H (SELENOH) is an oxidoreductase located in the nucleolus, and its biochemical levels decrease with selenium (Se) deficiency, as reported in mammalian research. This current investigation aimed to understand the impact of nutritional Se deficiency on gut microbial composition and metabolomic profiles. The Firmicutes/Bacteroidota (F/B) ratio, linked to various health conditions, was balanced for wildtype (WT) mice (1.06). In contrast, selenoh knockout (KO) mice associated with dietary Se deprivation had a significantly (p < 0.002) lower ratio (0.56), suggesting dysbiosis. It is believed that SELENOH levels decreased due to the Se deficient diet, and the selenoh KO mice exhibited alterations in microbial community composition and metabolite profiles, as supported by correlative analyses. With respect to the bacterial communities, significant differences between diets occurred for three taxa, including Akkemansia mucinphila, Bacteroides caecimuris, and Parabacteroides goldsteinii. Candida tropicalis, Malassezia restricta, and Cyberlindnera jadinii were three abundant fungal yeasts. Only Cyberlindnera jadinii exhibited significantly greater relative abundance between genotypes and was more abundant in the selenoh KO versus WT mice. Correlation analyses between bacterial and fungal taxa revealed both positive and negative relationships, but no specific trends were observed. The liver and serum metabolomic data contained similar amino acids, lipids, proteins, and carbohydrates. Using NMR spectroscopy, 112 liver metabolites were detected, while GC-TOF-MS analysis of the serum revealed the presence of 172, comprising both polar and nonpolar compounds. The metabolite levels varied significantly when analyzed using multivariate models such as PCA and PLS-DA (VIP scores), particularly for glucose, taurine, lactate, and UDP-glucose, which are associated with energy production and cellular health. Overall, the Se deficient diet had the most significant impact on the microbial community structure and the concentration of key metabolites within liver tissues and serum. Correlation analyses conducted across studies revealed significant linear relationships between metabolites and the microbiome. However, these differences were associated with bacterial and fungal taxa containing low relative abundances. Based on these findings, further investigation into the impact of SELENOH homeostasis on microbial and metabolite profiles should be conducted using selenoh KO mice under various nutritional Se dietary levels.

The Evaluation Of Traditional And Latency Based Functional Analyses On The Identification Of The Function Of Inappropriate Mealtime Behavior, Mallie N. Donald
Theses and Dissertations
Research indicates that up to 80% of children with developmental disabilities have feeding problems. Feeding problems typically coexist with the presence of inappropriate mealtime behavior which includes behaviors such as aggression, throwing food or utensils, or turning head away from the presented bite. As a result, functional analysis procedures are commonly used to determine the function of inappropriate mealtime behavior to later inform effective function-based interventions. Traditional functional analysis procedures utilize the measurement of the rate of inappropriate mealtime behavior. Several limitations exist within traditional procedures for the assessment of inappropriate mealtime behavior which include demands across all test and …
