The Role Of The Developing Microbiome In Mucosal Defense Of The Neonatal Gut, Emily G. Blosser Jan 2014

The Role Of The Developing Microbiome In Mucosal Defense Of The Neonatal Gut, Emily G. Blosser

All ETDs from UAB

Neonatal late-onset sepsis is invasive infection occurring after the first 48 hours of life, and one of the leading causes of death among preterm infants in the United States and abroad. Infections with Gram-negative bacteria, such as Klebsiella pneumonia, occurring when bacteria translocate across premature gut epithelium into the bloodstream, can be particularly severe. Preterm infants in the neonatal intensive care unit undergo intense antibiotic regimens due to high risk of infection. Paradoxically, prolonged exposure of preterm infants to empiric antibiotic therapy early in the hospital stay is associated with increased risk of intestinal infection and death after adjustment for …

Exposure To Methylmercury Via Fish Consumption In Ghana And An Evaluation Of Methylmercury Toxicity Under A Low Food Ration In Daphnia Pulex, Dzigbodi Adzo Doke

All ETDs from UAB

For many people of the world, fish is a primary source of protein, especially in countries like Ghana, where about 60% of the protein consumed is derived from fish. Fish advisories have been established by some nations to protect the public from harmful health effects linked to eating contaminated fish. Methylmercury (MeHg) is one such contaminant that has resulted in fish advisories. Fish advisories have not been developed in Ghana, although MeHg contamination of aquatic ecosystems is likely due to the long history of mercury (Hg) use in artisanal gold mining. To address this gap in our knowledge, I compiled …

The Direct Effects And Vertical Transfer Of Carbonaceous And Metal-Loaded Hydrochars In Aquatic Organisms, Katie Lauren Kohlenberg Jan 2014

The Direct Effects And Vertical Transfer Of Carbonaceous And Metal-Loaded Hydrochars In Aquatic Organisms, Katie Lauren Kohlenberg

All ETDs from UAB

Industrial use of reactive micro- and nano-sized carbonaceous hydrochar (CH) is expanding rapidly. These carbonaceous particulates are synthesized by the pyrolysis of biomass in an industrial process called hydrothermal carbonization (HTC) and have gained attention as a soil conditioner. Additionally, the HTC process is being expanded to coat heavy-metal nanoparticles, such as nano-copper and nano-iron, to prevent surface oxidation of these metals. These carbonaceous particles are likely to undergo secondary reactions with metals, toxicants, or other compounds. There is potential for these carbonaceous particulates to enter watersheds and have deleterious effects on aquatic food web dynamics. In this study, we …

Ksrp Ablation Enhances Lipolysis In White Adipose Tissue Through Reduced Mir-145 Expression, Yi-Yu Lin Jan 2014

Ksrp Ablation Enhances Lipolysis In White Adipose Tissue Through Reduced Mir-145 Expression, Yi-Yu Lin

All ETDs from UAB

White adipose tissue (WAT) releases fatty acids from stored triacylglycerol (TAG) for energy source. Here, we report that null mice for KH-type splicing regulatory protein (KSRP), an RNA-binding protein, resisted high fat diet (HFD) induced obesity. Target of deletion of KSRP regulates gene expression at multiple levels and enhances lipolysis in epididymal WAT (eWAT) due to up-regulation of genes promoting lipolytic activity. Expression of miR-145 is decreased due to impaired pri-miR-145 processing in Ksrp-/- eWAT. We show that miR-145 directly targets and represses Foxo1 and Cgi58, activators of lipolytic activity, and forced expression of miR-145 attenuates lipolysis. This study reveals …

Differences In How Bmi And Body Fat Distribution Influence Body Dissatisfaction And Self-Esteem In Caucasian And African American Early Pubertal Girls, Danielle Marie Lorch

All ETDs from UAB

Body dissatisfaction is among many psychological concerns related to obesity, particularly among pre-adolescent females. Though obesity prevalence estimates are higher among African American (AA) adolescent females, the limited data available suggests that they are less susceptible to weight-related body dissatisfaction than Caucasians. The purpose of the current study was to evaluate the relationship between BMI and body dissatisfaction and the relationship between BMI and self-esteem in obese AA and Caucasian girls, aged 7-11 years, and determine if these relationships are moderated by race. Furthermore, an examination of how total body fat and body fat distribution before and after a dietary …

The Role Of The Autophagy-Lysosome Pathway In In Vitro Models Of Neurodegeneration, Burton Mader Jan 2014

The Role Of The Autophagy-Lysosome Pathway In In Vitro Models Of Neurodegeneration, Burton Mader

All ETDs from UAB

Recent studies have provided strong evidence that alterations in protein degradation pathways, such as the autophagy-lysosome pathway (ALP), may contribute to neuronal dysfunction and death which lead to clinical symptoms diagnosed with various neurodegenerative diseases. Parkinson's disease (PD) is characterized by neuromuscular abnormalities resulting from the pathological loss of substantia nigra dopaminergic neurons and widespread detection of Lewy bodies, intracellular protein inclusions composed primarily of α-synuclein. Additionally, altered gene function regulating the expression of α-synuclein has been directly linked to the PD pathogenesis. Autophagy is an intracellular degradation process that when altered can lead to the accumulation neurotoxic proteins such …

Combined Effects Of Corexit Ec 9500a With Secondary Abiotic And Biotic Stressors In The Rotifer Brachionus Plicatilis, Michael Britt Williams

All ETDs from UAB

Following the Deepwater Horizon oil spill the dispersant Corexit EC 9500A (C-9500) was applied to facilitate rapid oil degradation. C-9500 toxicity has been evaluated on a number of marine species; however, many of these studies do not account for environmental conditions that may increase negative outcomes related to dispersant exposure in the wild. We examined lethality and behavioral effects of C-9500 exposure on the model marine zooplankton Brachionus plicatilis. We also evaluated interactions of abiotic and biotic stressors that may alter outcomes of exposure. C-9500 exposure at standard husbandry conditions (17.5ppt, 24°C, 200 rotifer*ml-1 density) produced a 24 hr median …

Risk Assessment And Staging Of Cardiometabolic Diseases, Fangjian Guo Jan 2014

Risk Assessment And Staging Of Cardiometabolic Diseases, Fangjian Guo

All ETDs from UAB

Obesity is associated with elevated risk for morbidity and mortality and has become an epidemic both in the United States and around the world. Insulin resistance is essentially involved in the pathogenic process of cardiometabolic diseases in obese people, which involves defects in glucose production by the liver and insulin-stimulated glucose uptake and utilization by peripheral tissues. Insulin resistance appears at an early stage of life and is the first step in the development of cardiometabolic diseases. Long-term insulin resistance will induce metabolic syndrome and prediabetes and eventually will cause type 2 diabetes and cardiovascular diseases. Obesity may exacerbate insulin …

Coevolution Of Sponges And Microbial Symbionts Across Ocean Basins, Zachary Lee Nolen Jan 2014

Coevolution Of Sponges And Microbial Symbionts Across Ocean Basins, Zachary Lee Nolen

All ETDs from UAB

Sponges (phylum Porifera) can comprise a large portion of benthic communities in freshwater and marine environments. Because sponges possess simple body plans and can have substantial phenotypic plasticity within species, reconstructing phylogenies of Porifera based upon morphologies alone has proven difficult. With the advent of nucleic acid sequencing technologies, interest in sponge phylogenetics has significantly increased among researchers. Additionally, sponges host a wide range of microbial symbionts, including the cyanobacterium Synechococcus spongiarum. This study examined the evolution of both sets of organisms in the symbiotic relationship between Aplysina sponges and Synechococcus cyanobacteria. In Chapter 3, gene sequences coding for the …

Making Room For A Restorative Response To Conflict: Challenging The Retributive Paradigm In American Journalism, Cynthia Duggan Mwenja Jan 2013

Making Room For A Restorative Response To Conflict: Challenging The Retributive Paradigm In American Journalism, Cynthia Duggan Mwenja

All ETDs from UAB

Reactions to current events from across the political spectrum highlight a journalistic retributive narrative framework that is ubiquitous in the American media. News articles from the childhood obesity debate support claims that journalists on both left and right interpret this story - and by implication, all stories - through a retributive cultural lens. Burke's rhetorical analysis tool, dramatism, is used to examine the rhetoric on all sides of the issue and demonstrate the common retributive aspects of the narratives, regardless of the social or political orientations of the writers and their affiliations. The retributive narrative is connected to American justice …

An Investigation Of The Sublethal Effects Of Carbon Dioxide On The Common Sea Urchin Lytechinus Variegatus And The Carbonate Chemistry Of Its Nearshore Habitat, Roberta Challener

All ETDs from UAB

Increases in CO2 concentrations, whether from accumulation of metabolic waste under intensive culturing conditions or from increases in atmospheric levels, lead to decreases in seawater pH and carbonate saturation states. Lytechinus variegatus survive chronic exposure to hypercapnic conditions (pH 7.4 -7.8, partial pressure of CO2 (pCO2) 1738-4290 μatm) in synthetic seawater, yet aspects of growth and development are affected. Rates of embryonic and larval development were delayed and larval size and arm length reduced under high pCO2 conditions. Fecal production rates were higher and ash absorption efficiency (%) was lower in individuals exposed to hypercapnic conditions, suggesting that the ability …

Intrinsic Properties Of Rna Polymerase I And Trans-Acting Factors Control Transcription Elongation Efficiency, Olga V. Viktorovskaya

All ETDs from UAB

Transcription of ribosomal (r) DNA by RNA polymerase I (Pol I) is the initial step of ribosome synthesis. Pol I transcription is unique in its high rate of initiation, specific organization within the nucleolus and tight connection to cell growth and proliferation. Moreover, transcription elongation by Pol I is functionally coupled with rRNA processing and assembly of the ribosomes. Regulatory insights into transcription elongation by Pol I and its interface with rRNA processing are limited, despite decades of research. To fulfill that gap, we asked several important questions: Do the obvious functional divergences between Pol I and other eukaryotic polymerases …

Association Between Cruciferous Vegetable Intake And Risk Of Colorectal Cancer Among Men In Shanghai, China, Emily Vogtmann Jan 2013

Association Between Cruciferous Vegetable Intake And Risk Of Colorectal Cancer Among Men In Shanghai, China, Emily Vogtmann

All ETDs from UAB

Colorectal cancer (CRC) is a major global health concern and the intake of certain foods, such as cruciferous vegetables, has been studied for their potential protective effects against cancer development. The observed association between cruciferous vegetable consumption and CRC has been inconsistent, possibly related to glutathione S-transferase (GST) gene polymorphisms. Therefore, we aimed to (1) evaluate the association between fruits and vegetables, including cruciferous vegetables, on the risk of CRC; (2) determine factors associated with urinary isothiocyanate (ITC), a biomarker of cruciferous vegetable intake; and (3) evaluate the association between cruciferous vegetable consumption and CRC and to estimate the potential …

Glioma-Vasculature Interactions, Stacey Watkins

All ETDs from UAB

Malignant gliomas are highly invasive brain tumors, which lack effective treatment options. To date, the standard therapy includes surgical debulking followed by chemotherapy and radiation. Despite efforts to eradicate the disease, the median patient survival time is only 14 months. In an attempt to discover novel therapies, research has focused on understanding the heterogeneous biological mechanisms employed by these cells. Uniquely, they do not metastasize through the vasculature or lymphatics like other solid cancers but alternatively, glioma cells utilize the abluminal surface of the vasculature to guide invasion and migration throughout the brain. The intimate association between glioma cells and …
