Obesity And Mortality In Us-Residing Hispanic Adults, Carrie Howell
All ETDs from UAB
Previous epidemiological studies observed the lack of an association between increased body mass index (BMI: kg/m2) and all-cause mortality in US-residing Hispanic adults. The purpose of this dissertation was to examine the validity of three hypothesized explanations for the absence of significant associations. Using data on Hispanic participants from the National Health and Nutrition Examination Survey (NHANES) [1988-1994 and 1999-2004] and the National Health Interview Survey (NHIS), this dissertation examined whether: (1) BMI was associated with cause-specific mortality; (2) measures of body composition was associated with all-cause mortality; and (3) the BMI-all-cause mortality association differed as a function of Hispanic …

Ecology And Physiology Of Antarctic Macrophytes Under The Influence Of Abiotic And Biotic Stressors., Kathryn M. Schoenrock
Ecology And Physiology Of Antarctic Macrophytes Under The Influence Of Abiotic And Biotic Stressors., Kathryn M. Schoenrock
All ETDs from UAB
The physiology of many species of Antarctic marine algae was evaluated under a variety of biotic and abiotic factors found or predicted for the western Antarctic Peninsula. The potential biological stressors, filamentous algal endophytes, had few effects on their macrophyte host's physiology which may be the cause for their persistence in this marine community. Adversely impacted hosts include Pachymenia sp. and Iridaea cordata. In areas of high endophyte infection Pachymenia sp. was significantly less resistant to forces that could penetrate their thalli. Maximum quantum yield near endophyte infection was significantly lower in I. cordata. Endophyte abundance is significantly lower in …

Unraveling The Mechanisms Of Skeletal Muscle Hyperplasia: Juxtaposing Divergent Growth Paradigms, Jacob Michael Froehlich
All ETDs from UAB
During the course of vertebrate evolution, two major growth paradigms have appeared: determinate, one in which an animal's final size is largely governed by predisposed genetic potential; and indeterminate, a paradigm involving life-long, largely environmentally governed somatic growth. Of the tissues constituting an adult vertebrate, skeletal muscle comprises ≥60% of that organism's mass, making it an important factor in overall body growth. To better understand the process by which many teleost fishes grow throughout their natural lifespans, the clade Danioninae and the model rainbow trout (Oncorhynchus mykiss) were utilized in a comparative manner. Contrary to current hypotheses, fish with indeterminate …

Environmental change, especially rapid urbanization, has measurable effects on human health. Over 70 percent of the global population is expected to live in urban areas by 2025, and at least 1 in 3 of these individuals will live in extreme poverty. Living in a slum or shantytown exposes individuals to health and safety risks including inadequate sanitation, lack of access to clean water, air pollution, violence, over-crowding and risk of infectious disease. Remote sensing technologies are an effective tool for detection and prediction of areas with significant land use change, which enables identification of populations with the highest risk of …
Illuminating The Physiology And Ecology Of The Wound-Induced Macroalgal Oxidative Burst, Ruth Ellen Mcdowell
Illuminating The Physiology And Ecology Of The Wound-Induced Macroalgal Oxidative Burst, Ruth Ellen Mcdowell
All ETDs from UAB
The role of reactive oxygen species (ROS) in the macroalgal wound response was investigated with emphasis on their occurrence, source, and ecological role. In a survey of Antarctic macroalgae, an oxidative response to wounding was common and ROS in seawater decreased the feeding rate of sympatric amphipod grazers. The macroalgal oxidative response was also sensitive to light. In contrast to the current understanding of the macroalgal oxidative burst, initial wound-induced ROS from the temperate kelp Saccharina latissima were light-dependent and arose from disrupted photosynthetic electron transport rather than from a defense-related enzyme such as an NADPH-oxidase. Furthermore, the light-dependence of …

Syndecan Knockdown In The Insulin Producing Cells Of Drosophila Melanogaster Affects Energy Metabolism And Life Span, Jonathan Lund Warren
Syndecan Knockdown In The Insulin Producing Cells Of Drosophila Melanogaster Affects Energy Metabolism And Life Span, Jonathan Lund Warren
All ETDs from UAB
Drosophila melanogaster is a powerful model organism for studying human metabolic disease due to the conservation of various signaling processes and pathways. The insulin producing cells (IPCs) in the brain of adult flies sense circulating nutrients and respond by producing three insulin-like peptides (dILP2, dILP3, and dILP5). Several studies have shown that dILPs play a major role in Drosophila reproduction, metabolism, growth, and longevity. Previous data showed that flies homozygous for a hypomorphic mutation in the Drosophila syndecan (dSdc) gene had defects in energy metabolism and lower expression of brain dilp2-3 and dilp5 genes. Syndecan is a transmembrane proteoglycan that …
Skeletal Muscle Stem Cell Function Following Burn Injury, Katie Leigh Wilson
Skeletal Muscle Stem Cell Function Following Burn Injury, Katie Leigh Wilson
All ETDs from UAB
The pathophysiological response to burn injuries involves severe inflammation and a hypermetabolic state, both contributing to prolonged muscle atrophy. However, the relationship between inflammation and hypermetabolism following burn injury is poorly defined. Catabolism results from energy storage depletion, in part due to futile substrate cycling, and preferentially involving amino acids. This rapid turnover of amino acids leads to massive, full body muscle wasting. The extent and duration of muscle loss is directly related to the total body surface area burned (TBSA). Severely burned patients may experience metabolic derangements and impaired muscle synthesis for up to two years. In order to …

Effects Of Biological, Environmental, And Nutritional Factors On Fecal Pellet Size And Morphology In The Sea Urchin Lytechinus Variegatus, Lacey Nicole Dennis
All ETDs from UAB
Sea urchins are an important economic resource for many international fisheries and are an important animal model in developmental biology. Currently, health of cultured sea urchins is evaluated by behavior or through invasive examination of internal tissues. Destructive sampling is not conducive to longitudinal studies and a non-invasive method of evaluating sea urchin health would have practical application. Evaluation of the egesta could provide a valuable predictor of physiological well-being. The size and morphology of fecal pellets produced by the sea urchin Lytechinus variegatus under a variety of environmental and nutritional conditions were characterized in terms of 2-dimensional area, length, …

Targeted Delivery Of Osteoinductive Peptides To Bone Graft Utilizing A Calcium Binding Domain To Enhance The Regenerative Potential, Jennifer Leigh Bain
All ETDs from UAB
Bone grafting procedures are common practice. Autogenous bone is considered optimal, however, complications associated with bone harvesting often lead clinicians to use off-the-shelf materials that have limited osteoinductivity. Alternatively, bioactive factors passively adsorbed onto various carriers are available. These materials, while effective, are expensive to produce, require supraphysiological doses, and have adverse side effects due to dissemination from the graft site. This dissertation aims to reintroduce osteoinductive factors to bone grafts to enhance regenerative capacity. Specifically, we utilized negatively-charged calcium-binding domains (polyglutamate) to anchor two osteoinductive peptides bone graft materials including an allograft, xenograft, alloplast, and bone cement. The peptides …

Circadian rhythms are the daily biological changes present within most organisms that occur in a predictable, approximately 24 hour pattern, even in the absence of external stimuli. These rhythms occur both at a global and cellular level, and although the molecular mechanics are highly conserved, their functions may vary depending on the tissues in which they are expressed. These functions include various aspects of metabolic processes such as satiety signaling and cellular proliferation. In order to explore the specific functions of circadian rhythms within adipocytes, a mouse model with Clock disruption driven by the fatty acid-binding protein 2 (aP2) promoter …

Dietary practices were evaluated using five dietary patterns derived previously using factor analysis in a sample of 21,636 African American and European American participants who completed the Block 98 Food Frequency Questionnaire in the REasons for Geographic And Racial Differences in Stroke (REGARDS) study. Logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI) measuring dietary pattern adherence of adults with diabetes …
The Roles Of Mammalian Tribbles Homolog 3 (Trib3) In Coordinating Energy Metabolism And Development Of Insulin Resistance, Wei Zhang
All ETDs from UAB
Insulin resistance in diabetics comprises of a reversible component treatable with intensive glycemic control and a non-reversible component present in pre-diabetes that may lead to the development of overt diabetes. The reversible component is induced and exacerbated by hyperglycemia in both uncontrolled type 1 and type 2 diabetes, a process known as glucose-induced insulin resistance (GIIR) or glucose toxicity. The tribbles homolog 3 (TRIB3) has been identified as a pseudokinase that inhibits Akt activity by physically blocking its phosphorylation site. Expression of TRIB3 has been associated with various signals such as endoplasmic reticulum (ER) stress and nutrient availability in pancreatic …

Interaction Between A Low-Iron Diet And Early-Life Methylmercury Exposure In Daphnia Pulex, Sherri Hudson
All ETDs from UAB
Methylmercury (MeHg) is a known neurotoxicant and bioaccumulates in fish, with exposure to humans in utero being of highest concern. Iron deficiency (ID) accounts for approximately 50% of anemia cases. Anemia is estimated to affect 1.62 billion people worldwide, and is particularly problematic during pregnancy and early life. Previous studies have shown that ID exacerbates toxicity associated with exposure to metals, including lead, manganese, and cadmium. The overall purpose of this thesis research is to investigate the interaction between a low-iron (Fe) diet and early-life exposure to MeHg in Daphnia pulex. I hypothesized when D. pulex are fed a low-Fe …

Relationship Between Diabetes And Indoor Air Pollution: An Exploratory Analysis, Sandeep Mishra
All ETDs from UAB
India has the second highest number of people with diabetes. The high prevalence of diabetes in India cannot be explained on the basis of established risk factors like obesity. The role of air pollution in diabetes has recently received attention. Studies have indicated the possibility that air pollution generated by traffic might be associated with increased risk of diabetes. Published literature lacks studies that assess the relationship between indoor air pollution and diabetes, although indoor air pollution can lead to higher levels of pollutants in house compared to traffic pollution. The current study determined the relationship between indoor air pollution …

Fatigue Testing Of Straight And Angled Abutments In A High Torque Dental Implant System, Rana M. Atieh
All ETDs from UAB
Root form dental implants are a common solution used today to replace missing teeth. However current designs still suffer from a number of limitations. Angled abutments are used for incisors, where maximum human bite forces are normally < 200N, while straight abutments are used for molars subjected to higher forces > 200 N. The aim of this study was to evaluate the mechanical performance of a novel dental implant system by fatigue testing straight and 15-degree angled abutments. It was hypothesized that the novel thread design will dissipate the load evenly throughout the implant allowing the system to withstand normal chewing forces. Implants with 4.2mm diameter were tested according to ISO 14801 in specimen …
