Gene Expression Analysis Reveals Dysregulation In Traumatic Brain Injury Leading To Tauopathy, Kristina M. Tosi

USF Tampa Graduate Theses and Dissertations

Traumatic Brain Injury (TBI) causes a cascade of detrimental events within neurons, contributing to a host of neurological diseases relating to dementia. In this study we have performed a meta-analysis comparing differentially expressed genes (DEG) in specific cell types such as neurons and microglia revealing inflammation as a common driver of neurological deficiencies post TBI. Inflammation and hypoxia are well characterized features of TBI; however, the molecular mechanisms causing tau hyperphosphorylation by tauopathy associated genes (TAG) post-TBI are currently poorly understood. Furthermore, there are limited in-vitro neuroinflammatory models that mimic primary and secondary TBI. We hypothesize that inducing hypoxia and …

Security Or Vulnerability? The Optics Of Data In The Humanitarian Sphere, Nicole M. Bennett, Hamid Ekbia

Genocide Studies and Prevention: An International Journal

Governments, humanitarian agencies, and non-government organizations increasingly resort to data-driven techniques to meet the challenges they face in dealing with growing mobile populations such as refugees. Such techniques originate in bureaucratic administrations of the 19th century and, even earlier, in slave trade and plantation accounting methods. They were then perfected in logistics and global supply chain management of the twentieth and twenty-first centuries, especially with the advent of information technology. We examine the application of these techniques in humanitarian cases, seeking to contextualize them within the framework of logistic security. To understand the drivers of this trend, we introduce the …

The United States Department of Health and Human Services (2018) recommends that teenagers engage in physical activity to improve their cardiovascular health and muscle and bone strength. Yet, most teenagers with and without autism spectrum disorder do not meet the recommended guidelines for physical activity. Research related to promoting physical activity has evaluated group contingencies, reinforcement-based interventions, and antecedent interventions; however, these interventions are time-intensive, require many resources, or are ineffective. The purpose of this study was to extend Allen and Iwata (1980) by reinforcing completion of a low-probability exercise to a specified criterion with access to a high-probability exercise. …

The Application Of Multi-Isotope Analysis To Assist In Geoprofiling Unidentified Decedents Within Florida, Liotta D. Noche-Dowdy

USF Tampa Graduate Theses and Dissertations

The biochemistry of human tissues can provide information for geoprofiling (geographic birthplace or migration patterns) of an unidentified decedent. Utilizing isotope analyses (both stable and radiogenic) from teeth, bone, nails, and/or hair reveals specific isotopic information that correlates to diverse geographic regions reflecting an individual’s birthplace and migration patterns. Isotope analysis of enamel and bone has been employed in bioarchaeology for decades to reconstruct the diet, health, and migration patterns of past populations. Isotope ratios measured from enamel can then be compared to isotope ratios measured from bone of the individual to track patterns of migration. The enamel from the …

3d Organ-Scale Models Of Tumor Growth And Treatment, Rafael Ramon Bravo

USF Tampa Graduate Theses and Dissertations

To understand the dynamics of cancer, mathematical oncologists have developed models of tumor growth and treatment response. Some models are mechanistic and approach tumor growth at the cell-scale, focusing on the evolution of cancerous cells within the ecology of normal tissue, and are often simulated with agent-based modeling. Other models are more clinically motivated and model tumor growth operating at the organ-scale, using patient data to predict treatment response, and are often simulated with partial differential equations. We developed the Hybrid Automata Library which includes both agent-based modeling and partial differential equations for modeling at either of these scales. We …
