The Noahic Pattern In Nicolas Rolin's Patronage: Jan Van Eyck's Rolin Madonna And Rogier Van Der Weyden's Beaune Altarpiece, Elizabeth Deschamps Blackford

All ETDs from UAB

In Rogier van der Weyden’s (1399/1400-1464) Beaune Altarpiece (fig. 1, c.1445-1451), Christ presides over the Day of Judgment while seated atop a rainbow. Previous analyses of the polyptych briefly mention the rainbow’s presence. However, in this thesis, I will show how the rainbow motif symbolizes a significant and, until now, undiscovered allusion instigated by the patron Nicolas Rolin (1376-1462), the chancellor of Burgundy, to Noah, the Old Testament patriarch. In the chancellor’s previous commission to Jan van Eyck (1390-1441), the Virgin and Child with Chancellor Nicolas Rolin (fig. 3, c.1435), Rolin first exhibited the Noahic allusion through the Drunkenness of …

Regulatory Elements Of Polyphosphate Biosynthesis, Marvin Qortez Bowlin Jan 2023

Regulatory Elements Of Polyphosphate Biosynthesis, Marvin Qortez Bowlin

All ETDs from UAB

Polyphosphate (polyP) is an ancient, conserved, inorganic biomolecule. Biological systems have adapted many functions for this high-energy molecule, ranging from immune regulation in mammals to gene regulation in prokaryotes. Of particular interest is its use in bacterial stress responses. Bacteria use polyP to resist hazardous environmental elements like toxic molecules or nutrient starvation. In many bacterial species, polyP is synthesized by polyphosphate kinases (PPKs). PPK – discovered in Escherica coli (E. coli) – hydrolyzes adenosine-5’-triphosphate (ATP) to synthesize polyP. Species that use PPK develop multiple pathogenic defects when PPK activity is impaired, including, among others, antibiotic susceptibility. There is no …

A Tale Of Two Waves: The Role Of Genomic Enhancers In Regulating Transcriptional And Epigenetic Responses To Neuronal Activitiy, Robert A. Phillips

All ETDs from UAB

The mesolimbic dopamine (DA) pathway, which consists of dopaminergic neurons that project from the ventral tegmental area (VTA) to the nucleus accumbens (NAc), is heavily implicated in drug addiction. Exposure to drugs of abuse results in increases in extracellular concentrations of DA in the NAc, which in turn activates an immediate early gene (IEG) expression program that primarily consists of activity-dependent transcription factors, such as the AP1 subunits Fos and JunB. IEGs engage a set of temporally and functionally distinct genes, termed the late response gene (LRG) expression program. While gene expression changes are critical for drug-dependent adaptations, two major …

Randomized Control Trial Of A Novel Dental Gel As An Adjunct To Scaling And Root Planing In Subjects With Stage Ii & Iii Periodontitis, Sarah Pham

All ETDs from UAB

The current standard of care for treating chronic periodontitis is scaling and root planing (ScRP) followed by supportive periodontal therapy (SPT) (Cobb et al., 2021; Ramfjord et al., 1987). The goal of ScRP is to eliminate supra- and subgingival bacterial deposits and to reduce periodontal pathogens, inflammation, and pocket depths (Greenstein, 2000). Although ScRP has been shown to significantly improve baseline clinical parameters, moderate to advanced cases may require additional surgical therapy which many patients resist (Stambaugh, 1981; Becker et al., 2001). Currently, no dentifrice used adjunctively has been proven to increase the therapeutic effects of scaling and root planing. …

Acceptability And Tolerability Of Ketone Supplements And Their Effects On Capillary Beta-Hydroxybutyrate Concentrations In Young Adults, Mickey Bolyard

All ETDs from UAB

Increased concentrations of circulating ketones via ketogenic diet (KD) have been associated with beneficial effects on a number of chronic conditions, including obesity, fatty liver disease, refractory epilepsy, and neurodegenerative diseases. KD has been associated with low sustainability and compliance, which has led to the creation and commercialization of exogenous ketones. However, past studies examining the effects of exogenous ketones in humans are very limited. In this study, we compared two different commercially available exogenous ketones, a ketone monoester (KME) and a ketone monoester-salt mix (KME+S), at two different doses (5 g and 10 g ketones).

Differential Mechanisms Of Intestinal Inflammation Drive Pathogenesis Of Diabetic Retinopathy In Type 1 And Type 2 Diabetes, Jason Levi Floyd Jan 2023

Differential Mechanisms Of Intestinal Inflammation Drive Pathogenesis Of Diabetic Retinopathy In Type 1 And Type 2 Diabetes, Jason Levi Floyd

All ETDs from UAB

Diabetic retinopathy (DR) is the most common microvascular complication of diabetes and, along with diabetic macular edema (DME), accounts for the greatest source of vision-threatening eye disease in the working-age community. DR is caused by weakening of the retinal vasculature, the blood-retinal barrier (BRB), by high levels of blood glucose (hyperglycemia), exacerbations of oxidative stress, and systemic inflammatory factors. Many of these inflammatory factors are metabolic by-products and cell membrane constituents of the gut microbiota, the resident community of microbial species which inhabit the lumen of the gastrointestinal tract. These factors are collectively termed gut microbial antigens (GMAs). In diabetes, …

Nero's Eastern Policy And The Peace Of Rhandeia, Henry Smith Jan 2023

Nero's Eastern Policy And The Peace Of Rhandeia, Henry Smith

All ETDs from UAB

This thesis will argue that Corbulo’s campaigns in Armenia and the subsequent Peace of Rhandeia were reflective of a longstanding foreign policy which had been adopted in the aftermath of the ambush at Teutoburg Forest and continued under Augustus’ successors. Nearly every aspect of the campaign, from the composition of the army, to the strategy employed by Corbulo, was an expression of the post-Augustan shift from expansion to defense. In place of conquest, the maintenance of prestige and the projection of power became the primary objectives of the Roman emperors, including Nero. The war in Armenia was fought to maintain …
