Evolutionary and Biochemical Studies of C₇-cyclitol Synthases and their Sunscreen Gene Clusters

Creator:: Osborn, Andrew
Abstract:: Sugar phosphate cyclases (SPCs) are enzymes involved in the biosynthesis of many important natural products. SPCs form a unique cyclitol during the early steps in the biosynthesis of many natural products. These natural products include rifamycin, which is chemically modified to rifampicin and used clinically as an antituberculosis drug, and...

The role of costimulation and adjuvants in the development of T cell effector and memory responses

Creator:: Maxwell, Joseph R.
Abstract:: T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

The influence of aryl hydrocarbon receptor activation on T cell fate

Creator:: Funatake, Castle J.
Abstract:: 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds are well-recognized for their immunosuppressive activity, which is mediated through an intracellular receptor and transcription factor, aryl hydrocarbon receptor (AhR). Laboratory animals exposed to TCDD are less resistant to infection and have severely impaired humoral and cell-mediated immune responses. This dissertation addressed the hypothesis that...

Uncovering the mechanism of IL-4-mediated T cell survival

Creator:: Moscibrocki, Cathleen M.
Abstract:: Although IL-4 is a well-characterized multi-functional cytokine, its role as a survival factor in T cells is not completely understood. In an attempt to uncover IL-4-mediated survival, we studied caspase activation in primary mouse T lymphocytes undergoing death by neglect, activation-induced or steroid-induced cell death. Here, we identify the executioner...

Investigations of regulatory T cell induction by 2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin during a graft-versus-host response

Creator:: Marshall, Nikki B.
Abstract:: The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...

"Land of War and Blood" : spectacular violence, conflicting medievalisms, and chivalric legacies in Sir Walter Scott's Ivanhoe, Mark Twain's A Connecticut Yankee in King Arthur's Court, and George R.R. Martin's A Game of Thrones

Creator:: Horton, Kaely
Abstract:: This thesis examines depictions of medievalism in three central texts: Sir Walter Scott's Ivanhoe, Mark Twain's A Connecticut Yankee in King Arthur's Court, and George R.R. Martin's A Game of Thrones. Each of these texts provides an entry point for exploring the ways in which English and American writers have...

Family-Teacher Relationships and Child Engagement in Early Care and Education

Creator:: Lewis, Hillary R.
Abstract:: The interactions young children have with teachers, peers, and tasks in early care and education (ECE) settings support development of social and academic skills. The degree to which families and teachers partner to support children’s development may contribute to child engagement. The current study aims to expand our understanding of...

Age-related response of isolated rat hepatocytes to menadione and (R)-[alpha]-lipoic acid

Creator:: Graves, Jason T.
Abstract:: Age-related decline in the capacity of endogenous antioxidant systems complicates pharmaceutical use by the elderly by potentially increasing the toxicity of some compounds. Of particular interest is chemical detoxification via glutathione (GSH) and attendant GSH-requiring detoxification enzymes, e.g. GSH peroxidases (GPX) and GSH S-transferase (GST). These enzymes have been shown...

Predictors of Family-Teacher Relationship Quality in Early Care and Education: Type of ECE Program, Family Socioeconomic Status and Adverse Childhood Experiences

Creator:: Lewis, Hillary R.
Abstract:: Families and early care and education (ECE) programs are two important contexts in which young children develop (Bronfenbrenner & Morris, 2006). Nearly half of all preschoolers are cared for in nonrelative care (e.g. child care center, preschool, Head Start, teacher’s home; Laughlin, 2013), and ECE programs have the potential to...

Condensation of a zeotropic mixture, R-454C, and its individual components, R-1234yf and R-32, in microfin tubes

Creator:: Matty, Ethan P.
Abstract:: This work compares the condensation heat transfer and pressure drop for zeotropic refrigerant R-454C and its individual components, R-32 and R-1234yf, in horizontal microfin tubes. One microfin tube has a 4 mm outer diameter, 0.18 mm wall thickness, and a surface area ratio of 1.56. The second tube has a...
