The Legacy Of Trauma: Exploring The Effect Of Generational Stress On Gut Health And Mental Well-Being In Black Women, Jocelynn Jones

Dissertations

This dissertation examines how generational trauma and chronic stress may relate to gut health and mood outcomes among Black women. Using a literature review design, this work brings together research on intergenerational trauma, gendered racism, Superwoman Schema, weathering, allostatic load, mood disorders, reproductive health disparities, and the microbiota-gut-brain axis. The central argument is that depression, anxiety, gastrointestinal symptoms, fatigue, reproductive vulnerability, and healthcare mistrust should not be understood as fully separate concerns when they may be shaped by shared stress conditions. The proposed integrated model does not claim that trauma directly causes gut dysbiosis or mood disorders. Instead, it suggests …

Heat Shock Factor 1 Signaling: A Novel Pathway Implicated In Rett Syndrome Pathophysiology, Sonia Gonzalez

Dissertations

Rett syndrome (RTT) is a severe neurodevelopmental disorder that is associated with loss-of-function mutations in the methyl-CPG binding protein 2 (MECP2) gene. There are limited therapeutic options to address the wide range of social, cognitive, motor, and respiratory symptoms that patients experience throughout their lifetime. To identify novel therapeutic targets, we leveraged a rare form of RTT known as MeCP2-mutation-negative or atypical RTT. Traditionally, RTT is first diagnosed clinically and then confirmed through the identification of mutations in the MECP2 gene. However, ~5% of RTT patients are found to be MeCP2-mutation-negative (atypical), despite sharing overlapping symptomology with typical RTT. We …

The state of Illinois is engaged in comprehensive early childhood systems work, and one of the vehicles driving this change has been the work …

An Examination Of Lysine Acetylation In The Context Of Bacterial Metabolism, Translation, And Regulation Of Gene Expression, Thomas Patrick Bank

Dissertations

Post-translational modifications are a critical tool bacteria employ to survive the challenges of microbial life. Acetylation continues to gain more recognition as a modification of unique importance because the sources of acetylation – acetyl-phosphate and acetyl-coenzyme-A – are critical metabolites associated with central carbon metabolism, acetate overflow metabolism and acetate assimilation. This suggests that acetylation, indelibly coupled to metabolic flux, integrates metabolic sensing with any cellular process or pathway where an acetylation alters the function of a protein. Intuitively, this makes sense. Of course, a bacterial cell would coordinate any cellular process closely with the amount of energy available to …

Privacy Preserving-Based Artificial Intelligence For Precision Agriculture, Partha P. Sengupta

Dissertations

The research work finds a solution to precision agriculture of cotton cultivation using artificial intelligence (AI) models. Two sets of model performance based on the application are selected namely a low resource and a high resource setting. This is because using drone surveys to capture images identifying the classes of stressed and unstressed cotton plantation requires limited model architecture and CPU based computation. Thus, traditional AI models were selected for low resource settings. Again, for high computation intensive models like transfer learning-convolution neural network (CNN) based architectures were grouped into high resource settings.
