Feed Comparison For Dietary Standardization Of The Sea Urchin Lytechinus Variegatus And Assessment Of Parental Dietary Copper Toxicity By Fertilization And Embryological Tests, Heath W. Garris

All ETDs from UAB

Toxicity tests monitoring the effects of anthropogenic substances on marine systems are considered an important part of environmental management. Sea urchin fertilization and embryological toxicity tests are successful in producing a graded response to toxicants, but standards for controlling the quality of parental urchins have not been developed. In Chapter 1, experimental populations of Lytechinus variegatus were fed either organic romaine lettuce and organic carrots, or a feed formulated for sea urchins for 13 weeks. Growth demographics were assessed and F1 progeny were compared for sensitivity to the toxicants copper sulfate, 1,3,5-trinitrobenzene, and sodium dodecyl sulfate by acute embryonic and …

Exercise Training Improves Premenopausal Women's Ability To Estimate Energy Expenditure After Weight Loss, Micah D. Greer Jan 2008

Exercise Training Improves Premenopausal Women's Ability To Estimate Energy Expenditure After Weight Loss, Micah D. Greer

All ETDs from UAB

Objective: Previously we have shown that total free living energy expenditure (TEE) and greater fitness was associated with reduced long term weight gain and improved ability to estimate TEE from physical activity (PA) questionnaires. In the current study, it is hypothesized that women will overestimate questionnaire self reported energy expenditure (QEE). Furthermore, weight reduced women who exercise train will be better able to estimate TEE compared to weight reduced women who do not exercise train. Design: The participants consisted of 35 European American (EA) and 49 African American (AA) pre-menopausal women. These women were evaluated while overweight and when weight …

Free -Knot Splines And Bootstrapping For Nonlinear Modeling In Complex Samples, Scott W. Keith Jan 2008

Free -Knot Splines And Bootstrapping For Nonlinear Modeling In Complex Samples, Scott W. Keith

All ETDs from UAB

Studies on body mass index (BMI) as it relates to headache or mortality have noted considerable nonlinearity. Approaches to rigorously analyzing these relationships have been limited to generalized linear models and survival models using either categorizations or polynomials of BMI. I have designed, evaluated, and implemented a piecewise linear logistic regression framework for modeling nonlinearity between a binary outcome and a continuous predictor, such as BMI, adjusted for covariates in complex samples. Least squares and maximum likelihood estimation methods were used to numerically optimize free-knot splines. Inference methods utilized both parametric and nonparametric bootstrapping. Parameter estimates were structured for interpretability …

Biomimetic Self -Assembled Nanomatrix For Bone Tissue Regeneration, Joel M. Anderson Jan 2008

Biomimetic Self -Assembled Nanomatrix For Bone Tissue Regeneration, Joel M. Anderson

All ETDs from UAB

Bone is a dense, connective tissue with an extracellular matrix (ECM) comprised of biological and organic/inorganic biphasic matrices. For this study, novel peptide amphiphile (PA) nanomatrices were synthesized to mimic the native bone ECM and evaluated with human mesenchymal stem cells (hMSCs) isolated from bone marrow. The ability of this nanoscale, biomimetic scaffold composed of PAs that are inscribed with cellular adhesive ligands to direct hMSC osteogenic differentiation without supplements, along with other cellular behaviors, was investigated. Typical osteogenic supplements include dexamethasone, β-glycerol phosphate, and ascorbic acid. The synthesized PA sequences were evaluated as two-dimensional nanomatrix coatings without the inorganic …

Air Pollution And Preterm Births In Atlanta, Georgia, Corey Masuca Jan 2008

Air Pollution And Preterm Births In Atlanta, Georgia, Corey Masuca

All ETDs from UAB

Exposure to ambient outdoor air pollution exposure is one of the many extraneous factors associated with preterm births. Many epidemiological studies involving preterm births and ambient air pollution have repeatedly indicated positive associations. However, for many such studies, results may be statistically significant but weakly associated or inconclusive. Such results may be primarily attributable to the fact that most studies include only single or multiple criteria air pollutants but not the total air pollution mixture of criteria air pollutants and air toxic pollutants (e.g., PAHs) to which people are actually exposed. This study assessed associations between pollutant classes, including criteria …

Microbial Biofilm Attachment To Caenorhabditis Elegans, Kevin Drace Jan 2008

Microbial Biofilm Attachment To Caenorhabditis Elegans, Kevin Drace

All ETDs from UAB

The closely related bacterial species Xenorhabdus nematophila, Yersinia pestis and Y. pseudotuberculosis make biofilms capable of adhering to the head of the model nematode Caenorhabditis elegans. Y. pestis uses biofilms to block the digestive tract of its vector, the flea, in order to enhance its efficiency of transmission. I investigated the role of biofilms in X. nematophila and found that, like its Yersinia sp. counterparts, production of biofilm requires a four-gene operon: hmsHFRS. X. nematophila is an insect pathogen and an obligate symbiont of the nematode Steinernema carpocapsae. However, an X. nematophila hmsH mutant that failed to make biofilms on …

Phenomenological Study: What Are Pre-Kindergarten Teachers' Lived Experiences With Children Identified With Conduct Disorder, Oppositional Defiance Disorder, And Attention-Deficit Hyperactivity Disorder In The Southeastern United States?, Danna Benefield Jones

All ETDs from UAB

To date, a vast amount of research has been conducted on disruptive behavior dis-orders such as conduct disorder (CD), oppositional defiance disorder (ODD), and atten-tion deficit hyperactivity disorder (ADHD. However, a paucity of research exists in spe-cific areas such as how teachers’ handle students diagnosed with these disorders. The cur-rent situation in pre-kindergarten may undermine the ability of these students to succeed in the school system. This is seen in the fact that a large number of these students are removed from pre-kindergarten programs across the United States (Webster-Stratton, Reid, & Hammond, 2004). Understanding pre-kindergarten teachers’ lived experiences in handling …

Relationships Among Anger, Patterns Of Anger Expression And Blood Pressure, Glucose, And Cortisol In Overweight School-Aged Children, Kimberly Nichols Jan 2008

Relationships Among Anger, Patterns Of Anger Expression And Blood Pressure, Glucose, And Cortisol In Overweight School-Aged Children, Kimberly Nichols

All ETDs from UAB

Overweight and obesity in school-aged children have become a major health issue. With overweight and obesity, children have increased risk of developing elevated blood pressure readings, glucose levels, and cortisol. Trait anger and patterns of anger expression have been shown to contribute to the elevations of blood pressure, glucose and cortisol in normoweight children and overweight adolescents. However, little research has been done with overweight school-aged children. The purpose of this study was to examine the relationships among trait anger and each of the patterns of anger expression (anger-suppression, anger-out, and anger-reflection/control) and blood pressure, glucose, and cortisol in overweight …

An Exploration Of Factors Related To Hypertension Control In African American And Caucasian Municipal Employees, Sunun Sinsuesatkul Jan 2008

An Exploration Of Factors Related To Hypertension Control In African American And Caucasian Municipal Employees, Sunun Sinsuesatkul

All ETDs from UAB

Hypertension is a major contributor to morbidity, mortality, and medical costs in the United States. African Americans (AAs) have the highest prevalence of hypertension in the world, exhibiting at least twice the rate for Caucasians in almost every age and sex group. AAs are also at higher risk for complications from hypertension than Caucasians. While several factors have been proposed as accounting for those differences, there is no consensus on which factors may be responsible; the reasons for disparities in hypertension control in AAs are complex, and need further investigation. This study explored relationships between multiple factors to identify how …

Thrombospondin Type-1 Repeats And Their Potential Role In Inhibiting Glioblastoma Angiogenesis, Joshua C. Anderson Jan 2008

Thrombospondin Type-1 Repeats And Their Potential Role In Inhibiting Glioblastoma Angiogenesis, Joshua C. Anderson

All ETDs from UAB

Thrombospondin-1 (TSP-1) is a 420 kilodalton homotrimeric protein; it is one of the first identified anti-angiogenic proteins found to be expressed in some normal tissues. Peptides derived from the type-1 repeat (TSR) domains of full length TSP-1 have been shown to have anti-angiogenic activity, and thus anti-tumor activity in some non-glioma tumor models. I hypothesized that peptides derived from the TSRs of TSP-1, such as ABT-510, could inhibit angiogenesis and thus malignant glioma tumor growth in vivo. I found that ABT-510 inhibited angiogenesis of the human brain microvascular endothelial cell (MvEC) in an in vitro tubulomorphogenesis assay. To determine the …

Occupational Stressors, Job Satisfaction, And Back Pain In Firefighters, Mantana Damrongsak

All ETDs from UAB

Occupational back pain is a significant health and safety problem in many industrialized countries for persons who are required to perform work-related forceful movement and lifting. Firefighters, an occupational group at high risk for back injury, perform many job tasks under hazardous work conditions. One-third of firefighters retire due to job-related health and safety problems and 49.4% of this group retire as a result of back pain, the leading cause of early retirements in firefighters. Most studies have examined factors influencing back problems among other workers, especially nurses and hospital workers, but few studies have investigated factors that influence back …

Metabolism Of Neutrophil-Deprived Chlorinated Isoflavones, Tracy Lyn D'Alessandro

All ETDs from UAB

Despite medical advances in both drug therapy and surgical techniques, Americans mostly die from heart disease. Many belong to the low- and middle-class families who do not have sufficient access to medical care due to its high costs. An alternative is the development of healthier lifestyles such as diet which may play a positive role in chronic disease management. Epidemiological and migratory studies suggest that soy plays a pivotal role in the decreased incidence of heart disease in East Asian countries, such as China, Japan, and Korea. The role of soy in cardiovascular disease progression has been the subject of …
