The Impact Of Weight Status On The Adoption Of Self-Care Behaviors Among Heart Failure Patients, Bern'nadette Knight Jan 2013

The Impact Of Weight Status On The Adoption Of Self-Care Behaviors Among Heart Failure Patients, Bern'nadette Knight

All ETDs from UAB

Self-care is a major component of heart failure management. Excess weight is a disease that may negatively affect a patient's ability to effectively practice self-care. The project aimed to assess 1) the relationship between weight status and heart failure self-care behaviors and 2) the modification of the relationship between social support and heart failure self-care by weight status. This cross sectional study utilized baseline data from a cohort of African-American and Caucasian participants diagnosed with heart failure. The heart failure cohort was formed from three larger studies (n=690) designed to assess the relationships among social support, self-care behaviors and hospital …


Virus-Induced Inflammation And Central Nervous System Development, Kate Kosmac Jan 2013

Virus-Induced Inflammation And Central Nervous System Development, Kate Kosmac

All ETDs from UAB

Congenital human cytomegalovirus (HCMV) infection is a complex cause of central nervous system (CNS) disease. Infection with HCMV during pregnancy results in virus transmission across the placenta and infection of the fetus. With a seroconversion rate in pregnant women between 1% and 4%, HCMV is the most frequently transmitted virus from mother to developing child. Each year between 2,000 and 4,000 infants will suffer from long-term neurologic deficits as a result of congenital infection. The well documented CNS sequelae resulting from congenital HCMV infection have described a wide range of damage without a specific set of pathologic markers for disease. …

Characterization Of Legal Highs And Their Pyrolysis Products, Emily Denise Bouso

All ETDs from UAB

Legal highs are any mind-altering substance produced and sold in a manner to avoid the legal consequences of illicit substances. They have been advertised and sold as Spice, Bath Salts, plant food, and research chemicals. Not only are these drugs presenting major problems to law enforcement, but also to health care providers. The exact composition for many of these substances is not known. Therefore, treatment for patients who have taken these drugs is limited to symptomatic care. Harmful exposure to these substances is not limited to the primary components within the drugs, but can include potentially toxic by-products that result …

O-Linked Beta-N-Acetylglucosamine (O-Glcnac) And The Mitochondrion, Christopher Calderon Jan 2013

O-Linked Beta-N-Acetylglucosamine (O-Glcnac) And The Mitochondrion, Christopher Calderon

All ETDs from UAB

O-linked beta-N-acetylglucosamine (O-GlcNAc) is a dynamic and ubiquitous posttranslational modification of serine and threonine residues on nuclear and cytoplasmic proteins. O-GlcNAc has emerged as an important regulator of cellular processes such as cell signaling, transcription, translation, apoptosis, and cell cycle regulation, among others. O-GlcNAc is thought to be a contributor to pathologies such as hyperglycemia and insulin resistance. O-GlcNAc has been viewed as an indicator of cellular energy levels and is associated with diabetic complications under nutrient excess. Other studies have shown that a variety of stress stimuli increase the levels of protein O-GlcNAc in mammalian cells, and this increase …


Adolescent Mothers: Factors Affecting Social And Sexual Decision-Making, Donna M. Campbell Jan 2013

Adolescent Mothers: Factors Affecting Social And Sexual Decision-Making, Donna M. Campbell

All ETDs from UAB

Adolescent pregnancy remains a public health concern despite decades of attempts to prevent it. The United States continues to have the highest adolescent pregnancy rates of any industrialized country (Kost, Henshaw, & Carlin, 2010). While adolescents of all ages (10-21 years) can become pregnant, pregnancy rates are highest among adolescents who are 15 to 19 years of age. Multiple factors have been identified that increase the likelihood of adolescent pregnancy and repeat pregnancy. Often times, adolescent pregnancy is the result of sexual risk-taking, which has been attributed to the changes that occur neurologically, physically, and emotionally (Reyna & Farley, 2006). …


Reckless Reevaluated: Containment Theory And Its Ability To Explain Desistance Among Serious Adolescent Offenders, Stephanie Michelle Cardwell Jan 2013

Reckless Reevaluated: Containment Theory And Its Ability To Explain Desistance Among Serious Adolescent Offenders, Stephanie Michelle Cardwell

All ETDs from UAB

Social control theorists posit that crime and delinquency occur among members in society because an individuals' behavior is not well regulated. Recent control theories have emphasized the importance of high self-control and strong bonds to society in deterring criminal behavior. However, one of the original theories of self-control has been largely ignored among scholars. Developed by Walter Reckless in the 1960s, containment theory suggests that individuals are pushed and pulled into crime. Pushes are elements that pressure individuals to engage in delinquency while pulls draw individuals away from accepted forms of behavior. The theory states that pushes and pulls are …


The Flow Of The Social: Developing A Constructal Systemic Approach To The Study Of Health Inequalities, William A. Anderson Jan 2013

The Flow Of The Social: Developing A Constructal Systemic Approach To The Study Of Health Inequalities, William A. Anderson

All ETDs from UAB

Society is a dynamic, living system. People, groups, institutions, and cultures are intricately interconnected. Changes in one area of society create changes in other areas. Causes and results may be closely linked or separated by time and space. Sociologists readily acknowledge this dynamic reality. However, our mainstream theories and methods often fail to account for it. Even after decades of research into social inequalities in health, medical sociology still seems far away from being able to offer any definitive ideas about why such inequalities exist and persist despite efforts to alleviate them. Medical sociology (and sociology in general) is centered …

The U.S. building industry constitutes the largest consumer of energy (i.e., electricity, natural gas, petroleum) in the world. The building sector uses almost 41percent of the primary energy and approximately 72percent of the available electricity in the United States. As global energy-generating resources are being depleted at exponential rates, the amount of energy consumed and wasted cannot be ignored. Professionals concerned about the environment have placed a high priority on finding solutions that reduce energy consumption while maintaining occupant comfort. Sustainable design and the judicious combination of building materials comprise one solution to this problem. A future including sustainable energy …


The Molecular Mechanisms Underlying Cardiac Hypertrophy Due To Volume Overload., Justin Andrew Barnes Jan 2013

The Molecular Mechanisms Underlying Cardiac Hypertrophy Due To Volume Overload., Justin Andrew Barnes

All ETDs from UAB

Mitral regurgitation (MR) is a common form of heart disease, but there are no approved medical therapies for MR or other cardiovascular conditions associated with hemodynamic volume overload (VO) and eccentric remodeling. We have previously shown that a standard heart failure treatment, ß-adrenergic system blockade (ß-RB), improves function in animal models of VO and in MR patients without attenuating the adverse eccentric hypertrophy that occurs in conjunction with VO. This paradox highlights how poorly we understand eccentric remodeling of the heart, and a better understanding of the molecular mechanisms at work in VO must be obtained before we can develop …

Participants were presented an impossible or moderately difficult mental addition task; half of them were led to believe that they could win a traditionally masculine incentive by meeting a certain performance standard and half of them were led to believe that they could win a traditionally feminine incentive if they met the same performance standard. In the feminine incentive group, Systolic Blood Pressure (SBP) during the work period was stronger under difficult than impossible conditions among women, but low under both difficulty conditions among men. In the masculine incentive group, blood pressure measures (SBP, diastolic blood pressure, and mean arterial …


Adapter Based Strategies For Adenovirus Vector Retargeting To T Lymphocytes, Matthew S. Beatty Jan 2013

Adapter Based Strategies For Adenovirus Vector Retargeting To T Lymphocytes, Matthew S. Beatty

All ETDs from UAB

Adenoviruses are the most commonly used gene therapy vector for cancer therapy clinical trials. While adenovirus has shown a great track record in a variety of cancer therapeutics it has not progressed as a vector system for the modification of T lymphocytes. One of the major roadblocks towards utilizing adenovirus for T cell therapy is the lack of coxsackie virus and adenovirus receptor on the cell surface of T cell lineages. Exploitation of alternative receptors has allowed adenovirus vectors to be utilized in a variety of cell types that native adenovirus type 5 cannot infect. Thus, retargeting adenovirus to an …


In-Vivo Characterization Of Cone Photoreceptor Packing Density With Adaptive Optics Scanning Laser Ophthalmoscopy In Different Racial Groups, Ernesto Blanco Rivero Jan 2013

In-Vivo Characterization Of Cone Photoreceptor Packing Density With Adaptive Optics Scanning Laser Ophthalmoscopy In Different Racial Groups, Ernesto Blanco Rivero

All ETDs from UAB

Cone photoreceptors are one of the two types of essential light sensitive cells that initiate the visual process in the human retina. A normal database of the cone density of healthy eyes may provide an important measure for diagnosing retinal diseases that cause photoreceptor loss, for monitoring disease progression, and for evaluating treatment out-come. Recent studies revealed that the foveal pit morphology, retina thickness, retinal nerve fiber layer (RNFL) thickness, and optic nerve head structure significantly correlated with racial background. We hypothesize that the cone density may be also modified by racial background. To test this hypothesis, I used a …

All ETDs from UAB

Astrocytes are the most numerous cells in the brain and play a critical role in maintaining homeostatic extracellular potassium ([K+]e). This process is mediated, in part, by a glial-specific, inwardly rectifying potassium channel, Kir4.1. Pharmacological inhibition, knock down, or complete knock out of this channel results in astrocytes with increased membrane resistance, depolarized resting membrane potential, and altered extracellular potassium dynamics. Subsequent to the dysregulation of [K+]e, Kir4.1 knockout (KO) animals suffer from ataxia, seizures, and early postnatal death. Interestingly, Kir4.1 has long been characterized as a seizure susceptibility gene. The importance of Kir4.1 is further underscored by recent studies …

New Mouse Models To Aid Studies Of The Role Of Primary Cilia In Limb Patterning And Bone Development, Amber Kathleen O'Connor

All ETDs from UAB

Hedgehog (Hh) signaling is required for many developmental processes, and causes several diseases and cancers. Described in chapter one below, vertebrate Hh sig-naling is dependent on the primary cilium (PC), a small organelle that extends from the surface of most mammalian cell types. A better understanding of how the PC modulates Hh signaling is important, as defects in the structure or function of PC result in severe human disorders termed the ciliopathies. For example, patients with Meckel-Gruber Syndrome have extra digits and neural tube defects, which are Hh both related pheno-types. In chapter two we sought to further understand the …

Phospho-Erk And Amyloid Beta: Targets Of Estrogen In The Brain, Thomas Reed Peavy Jan 2013

Phospho-Erk And Amyloid Beta: Targets Of Estrogen In The Brain, Thomas Reed Peavy

All ETDs from UAB

Estrogen replacement therapy (ERT) has been shown to improve memory function in menopausal women, but increases hormone sensitive cancers, prompting a more targeted investigation of estrogen's action in learning and memory to develop more targeted therapeutics. Estrogen improves performance on the novel object recognition task by increasing phosphorylation of extracellular signal-regulated kinase (pERK) within minutes in the hippocampus. Dr. Lori McMahon's lab showed that the improvement in novel object recognition can be seen 24 hours after subcutaneous injection of proestrous levels of estrogen (referred to as E24). Whether a corresponding increase in pERK occurs at the E24 time point had …

Characterization Of The Retina In The Alpha 7 Nicotinic Acetylcholine Receptor Knockout Mouse, Marci Lynn Smith Jan 2013

Characterization Of The Retina In The Alpha 7 Nicotinic Acetylcholine Receptor Knockout Mouse, Marci Lynn Smith

All ETDs from UAB

Acetylcholine receptors (AChRs) are involved in visual processing and are expressed by inner retinal neurons in all species studied to date (Keyser et al., 2000; Dmitrieva et al., 2007; Liu et al., 2009), but their distribution in the mouse retina remains unknown. Reductions in alpha 7 nicotinic AChRs (nAChRs) are thought to contribute to memory and visual deficits observed in Alzheimer's and schizophrenia (Coyle et al., 1983; Nordberg et al., 1999; Leonard et al., 2006). However, the alpha 7 nAChR knockout (KO) mouse has a mild phenotype (Paylor et al., 1998; Fernandes et al., 2006; Young et al., 2007; Origlia …

Effects Of Light Spectra And Uv Radiation In Relation To Dietary Carotenoids On The Sea Urchin Lytechinus Variegatus, James Christopher Taylor Jan 2013

Effects Of Light Spectra And Uv Radiation In Relation To Dietary Carotenoids On The Sea Urchin Lytechinus Variegatus, James Christopher Taylor

All ETDs from UAB

An important factor in the marketability of sea urchin gonad is color. A marketable color is suggested to be dependent upon the in vivo accumulation of red and yellow carotenoid pigments within the gonad. Carotenoids obtained through the diet can be modified in sea urchins, but the function of these carotenoids is unknown. We hypothesize that differential light exposure can affect carotenoid deposition and, as a consequence, gonad color in sea urchins. We performed two experiments to determine if light spectra affect gonad color of Lytechinus variegatus. In the first experiment, urchins were fed a formulated feed supplemented with or …
