Distribution Characteristics And Ecology Of The Near Shore Marine Finfish Assemblage Inhabiting Northeastern U.S. Waters, Ethan Dwight Estey

Open Access Dissertations

While the near shore marine environment has been demonstrated to be a productive habitat, little is known about this finfish resource in this habitat in the northeastern U.S. This is primarily due to the difficulties of sampling in this environment, high variability in fish distributions, and lack of a standardized sampling approach, so as to be able to compare different studies. The focus of this work is to better understand the ecology of the near shore marine finfish distribution in the northeastern U.S. This is accomplished through identifying the finfish species inhabiting the surf zone environment and providing a description …

An Oral Strategy For Training Leaders Among The Aztec Indians, Anthony Conner

Doctoral Dissertations and Projects

Today there are over 150 Unengaged Unreached People Groups and Unreached People Groups in Mexico. Current methods of outreach are missing the mark with the indigenous people groups. Leaders are poorly equipped to take the Gospel to these least reached areas. The purpose of this project is to research and implement a program to train leaders in an indigenous context in Southern Mexico. The development of this program is based on the biblical mandate to reach all people groups, communication among indigenous peoples as affected by culture and worldview, surveys and interviews with missionaries and national leaders, and special considerations …

Preliminary Injunction Standards In Massachusetts State And Federal Courts, Arthur D. Wolf

Faculty Scholarship

Concurrent jurisdiction frequently allows attorneys the choice of filing a complaint in state or federal court. State courts presumptively have jurisdiction over claims rooted in federal law. At times, state courts are required to entertain federal claims. Similarly, federal courts have authority over state claims because of diversity, federal question, and supplemental jurisdiction. Many claims are rooted in both state and federal law, such as antitrust, civil rights, environmental, consumer protection, and civil liberties. Confronted with the choice of state or federal court, the attorney must evaluate a variety of factors before deciding in which court to file.

[Including But Not Limited To] Violence Against Women, Giovanna Shay

Faculty Scholarship

This Article highlights three developments in criminal justice in 2012 that marked the move toward more gender-inclusive anti-violence movements: the FBI’s adoption of a gender-neutral definition of rape; the debate regarding the reauthorization of the Violence Against Women Act (VAWA); and the promulgation of new Department of Justice (DOJ) regulations under the Prison Rape Elimination Act of 2003 (PREA). These recent developments reveal a growing movement towards more gender-inclusive conceptions of rape and intimate partner violence. The change to a more gender-inclusive approach will have many implications for criminal justice policy and institutions. One critical project is to ensure that …

The Phenotypic Expression Of Usp14 Deficiency Is Dependent Upon Genetic Background, Andrea Gail Marshall

All ETDs from UAB

The ubiquitin proteasome system (UPS) plays a critical role in regulating a diversity of cellular processes that are essential to neuronal function, such as synaptic transmission, axon guidance, and neurite outgrowth. Dysfunctions of the UPS are linked with many neurodegenerative disorders, including motor neuron diseases like spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS), although it is not known how UPS dysfunction contributes to disease pathology. The proteasome, an approximate 2.5 megadalton protein complex comprised of a 20S core particle and 19S regulatory particle, is the site of ubiquitin-mediated proteolysis in the cell. Recent studies have linked ubiquitin specific …

In Vitro Prevascularization Of 3d Tissue Constructs, Lauren Marshall

All ETDs from UAB

There is a need for more effective therapies to combat breast cancer. One reason for the inefficiency of therapeutics is that testing technologies currently employed in drug discovery and development are not reliable when transitioning drugs into human clinical trials. To supplement the currently used in vitro cell culture studies and in vivo animal studies, an in vitro three-dimensional breast tumor system has been suggested with integration of human cells, hydrogel biomaterials, 3D architecture, and endothelialized microchannels. Therefore, the objective of the thesis project, as an initial step in fabrication of the supplemental system for drug testing, is to fabricate …

Cd5 Regulation Of T Helper Cell Differentiation And Cytokine Signaling, Donald J. Mcguire

All ETDs from UAB

CD5 is expressed on T and B1a cells and is an important regulator of cell survival and activation. Engagement of CD5 promotes cell survival through the activation of the serine threonine kinase CK2. Mice with genetic abrogation of CD5 binding to CK2 (CD5∆CK2bd) exhibited reduced severity of experimental autoimmune encephalomyelitis that was associated with increased activation induced cell death. In addition to inhibiting cell death, CD5 activation of CK2 significantly enhances Th17 differentiation. Loss of CD5-CK2 signaling reduces the generation of Th17 cells despite an unexpected increase in pSTAT3 levels. The mechanisms of CD5's enhancement of Th17 differentiation have not …

Effects Of Nicotine On The Human Visual System: 1) Color Perception; 2) Processing At The Cortical Level, Naser T. Naser

All ETDs from UAB

The visual system is sensitive to various types of chemical substances, including nicotine. Nicotinic acetylcholine receptors (nAChRs) are found in the nervous system, including the retina. These receptors play a role in modulating signals within the visual system. It has been shown that smoking affects color vision, and visual evoked potentials (VEPs). But few studies have been devoted to understanding the effects of nicotine alone. The purpose of this research was to examine the effects of oral administration of nicotine in human adults, who are non-smokers, on color vision, and visual cortical processing. Previous studies on adult smokers revealed that …

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 …

All ETDs from UAB

Dengue virus (DENV) has become a huge public health concern around the world with no vaccine or antivirals available. More than one-third of the world's population is living in areas at risk of infection. To conquer the dengue disease, a better understanding of virus-host interactions and development of the appropriate therapeutic treatments are required. In this dissertation, we first broadly reviewed the factors involved in dengue viral entry and the role of tight junctions as a pathogen target. Second, we developed, optimized and validated a high throughput screening (HTS) assay for anti-dengue virus drug screening. Taking advantage of using live …

Identification Of Staphylococcus Aureus Sortase A Inhibitors As Potential Antibacterial Agents, Bala Chandra Chenna

All ETDs from UAB

Staphylococcus aureus (S. aureus) is the causative organism for a wide range of infectious diseases from superficial skin infections to dangerous bacteremias. Six pathogens named ESKAPE pathogens are responsible for majority of antibiotic resistant bacterial infections. MRSA is the single most prevalent ESKAPE pathogen. Many of the nosocomial MRSA strains are multi-drug resistant, and even methicillin-sensitive strains can be deadly. S. aureus has recently taken on a new role in causing an escalating number of community-acquired infections in non-hospitalized persons without predisposing risk factors. Due to the increase in the number of infections caused by multi-drug resistant S. aureus and …

Comparisons Between Electrophysiologic Assessments Of Visual Function And Histological Findings Of Cone Photoreceptors In Light-Damaged Albino Rats, Molly Clark

All ETDs from UAB

The purpose of this project was to investigate the etiology of decreased cone-driven vision in the light damage model of retinal degenerations. Experimental albino rats underwent moderate, low-intensity light damage for 10 days. Electroretinography was utilized to assess physiologic function of the rod- and cone-driven retinal function in the experimental and control (sibling) rats. Immunohistochemical staining for cone arrestin antibody identified cone photoreceptors, allowing quantification of cone density and comparison to the decline in functional vision. In this experiment the light-damaged rats showed decreased rod- and cone-driven function with partial recovery of responses 30 days later. Outer nuclear layer thickness …

Selection And Evolution Of Pneumococci In Response To Conjugate Vaccines, Christina M. Croney

All ETDs from UAB

Pneumococcal conjugate vaccines (PCVs) containing subsets of the >90 capsular polysaccharide antigens have been successful as a means of decreasing invasive and non-invasive pneumococcal disease worldwide. However, this success is limited to the specif-ic capsular serotypes against which PCVs are formulated and studies have reported the increase of nonvaccine serotypes. The 13-valent pneumococcal conjugate vaccine (PCV13) was introduced in the United States in 2010 for the prevention of invasive pneumococcal disease (IPD) and otitis media and was released without efficacy data. In this study we set out to 1) determine potential efficacy for invasive and noninvasive pneumococcal disease and 2) …

Utilizing A Hydroxyapatite-Binding Domain To Deliver Bone Regenerative Molecules To Hydroxyapatite And Allograft Bone To Enhance Osteogenesis, Bonnie Kathleen Culpepper

All ETDs from UAB

Hydroxyapatite (HA) makes up the mineral component of bone, and synthetic HA is commonly used to coat metal implants for use in dentistry and orthopedics. Additionally, allograft and synthetic HA are common alternatives to autograft bone, to circumvent the complications associated with a second surgery site. While both HA and allograft are known to be osteoconductive, osteoinductivity is limited. In this work, we developed methods for anchoring osteoinductive factors onto multiple types of HA biomaterials and human allograft bone, with the goal of enhancing their osteoregenerative potential. Specifically, a HA-binding domain, heptaglutamate (E7), modeled on bone-binding domains within native proteins, …

Neutropenia And Progenitor Cell Mobilization In Ap3-B1 Mutant Pearl Mice, Matthew Vallejo

All ETDs from UAB

Mutations in the AP3-ß1 gene are known to cause Hermansky-Pudlak syndrome type 2 (HPS2) in humans and canine cyclic hematopoiesis (CH) in gray collie dogs. HPS2 patients have severe congenital neutropenia (SCN), and dogs have cyclic neutropenia (CN). The mechanism behind neutropenia is uncertain. Pearl mice have an AP3-ß1 mutation, but whether they actually have neutropenia has not yet been evaluated. This dissertation presents a discussion of the evaluation of neutropenia in pearl mice, hematopoietic progenitor cell mobilization defect in pearl mice and finally an evaluation of methods of dog-to-mouse xenotransplantation to establish a xenotransplant model of the dog hematopoietic …

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 …

Hur Regulation In Central Nervous System Disorders, Crystal G. Wheeler

All ETDs from UAB

In inflammatory diseases of the central nervous system (CNS), astrocytes play a major role in the systemic response to disease by either enhancing or limiting the inflammatory response through secretion of growth factors or cytokines. HuR RNA binding protein regulates many genes involved in inflammation. Inflammatory diseases such as brain tumors, Amylotrophic Lateral Sclerosis (ALS), and Multiple Sclerosis (MS), have been linked to HuR, by our laboratory and others. To determine whether astrocytic overexpression of HuR would regulate inflammation in diseases of the CNS, we designed a transgenic mouse in which the HuR gene is overexpressed. In the first study, …

Neural Mechanisms Supporting The Learning-Related Emotional Response To A Threat, Kimberly H. Wood

All ETDs from UAB

Successful regulation of the emotional response to a threat allows one to react more effectively under threatening conditions. The prefrontal cortex (PFC) and amygdala are key brain regions that mediate the regulation and expression of emotion. We employed Pavlovian fear conditioning to investigate the neural mechanisms that influence the emotional response to a threat. These procedures were designed to investigate conditioned diminution of the unconditioned response (UCR). The specific aims were to better understand the role of associative learning, expectation, controllability, and predictability in modulating UCR expression. This project employed functional magnetic resonance imaging (fMRI) to assess the magnitude of …

Impulsivity As A Predictor Of Smoking Cessation Outcomes In Bupropion Treatment Of Community Corrections Smokers, Adam Clay Perkins

All ETDs from UAB

Cigarette smoking is the leading cause of death and disability in the United States. Prevalence of smoking among participants in community corrections far exceeds those in the general population. The purpose of the study was to examine predictors of smoking cessation outcome among community correction participants who were enrolled in a randomized control trial that used bupropion to treat tobacco dependence. This study found that inattention was a significant barrier to treatment. Specifically, performance on measures of attention including number of omissions errors on the Conner's Continuous Performance Task - Second Edition (CPT-II) and time to complete Trails A were …

Non-Random Snp Formation And Contextual Bias Within Murine And Hominid Genomes, Zackery Ezekiel Plyler

All ETDs from UAB

Single Nucleotide Polymorphisms (SNPs) are traditionally seen as forming in a stochastic manner, with final distribution ascribed to processes such as purifying natural selection, genetic drift, shift, etc. The present study investigated contextual biases that underlie SNP patterns in 16 distinct murine strains, and tested relevance of these observations to human genomic DNA. We establish stereotypic nucleotide motifs that surround single base replacements in mammalian genes and propose a novel mechanism of SNP regulation. The findings contrast traditional notions in which SNPs occur `randomly' followed by purifying selection or are attributable to more `neutral' (unselected) formation. Instead, we propose that …

Epigenetic Regulation Of Hippocampus-Dependent Learning, Laura Qadri

All ETDs from UAB

Knowledge of the molecular mechanisms that underlie learning and memory has advanced a great deal. Research into the role of epigenetics, or modifications above the genome, has the promise of providing an even greater understanding of the precise mechanisms involved in memory formation. Studies of epigenetic regulation of memory in the rodent hippocampus have primarily focused on associative learning using contextual fear conditioning. While these studies have provided valuable insight into the role that epigenetics plays in cognition, it remains to be seen whether the findings generalize to other forms of hippocampus-dependent learning. This work examines the role of epigenetic …

Role Of Gsk3 In The Immunopathogenesis Of Eae, Amber Rowse

All ETDs from UAB

Lithium, a glycogen synthase kinase 3 (GSK3) inhibitor, ameliorates experimental autoimmune encephalomyelitis (EAE), the murine model of multiple sclerosis (MS) in different mouse models. However, the mechanism of lithium's attenuation of EAE and the role of GSK3 in these processes are currently unknown. IFN-g producing Th1 cells and IL-17-producing Th17 cells are both effector cells in MS and in EAE models. However, relapsing remitting MS patients segregate into Th1 or Th17 serum cytokine signatures and each is differentially responsive to IFN-ß therapy, a first line therapy for MS. Studies in this dissertation revealed a differential effect of lithium on Th1 …

The Relationship Between Inflammatory Biomarkers And Cognitive Function In Older Adults, Andrea C. Sartori

All ETDs from UAB

Recent literature indicates associations between inflammation, aging, and cognitive function. Inflammatory processes have also been implicated in the onset of pathological and neurodegenerative conditions. Current study aims were to examine the associations between inflammatory biomarkers and cognitive function in older adults, and to explore the interrelationships of inflammatory biomarkers, depressive symptoms, health conditions, and cognitive function. Two studies were utilized for the current project: 1) a cross-sectional sample of sedentary older adults aged 65+ from the Physical and Cognitive Exercise Study (PACES; n=54); and 2) a longitudinal study (UAB Study of Aging) of community-dwelling older African Americans and Caucasians (n=393). …

Role Of Endothelial Mannose Residues In Monocyte Adhesion Under Flow, David Wayne Scott

All ETDs from UAB

Atherosclerosis is a chronic inflammatory disease of the vessel wall and underlying cause of most cardiovascular disease. Much is understood about the nature of atherosclerosis development, including contributions from leukocytes that drive the disease process forward. The general process by which leukocytes are trafficked to sites of atherosclerosis development, and sites of inflammation in general, is understood and relies upon endothelial expressed protein adhesion molecules which serve as ligands for cognate leukocyte receptors. While these adhesion molecules share the post-translation modification of N-glycosylation, relatively little is known as to what functional role these modification plays in: i) interactions of leukocytes …

Epigenetic Markers In The Developing Postnatal Brain, Rebecca Kaye Simmons

All ETDs from UAB

Epigenetic mechanisms provide a critical and plausible mechanism by which genes and the environment can interact and have been implicated in a number of diseases and disorders. In order to better understand how epigenetic mechanisms go awry in a diseased brain we must first understand how epigenetic mechanisms unfold during normal development. The present body of work begins to examine the role of DNA methylation in normal development and how it may contribute to a rodent model of emotion dysfunction. Using a variety of techniques, we evaluated the transcript, protein and functional output levels of DNA methyltransferase1, -3a, and -3b …

Consumptive And Non-Consumptive Effects Of Predatory Fishes On Lobster In Southern Maine, Erin B. Wilkinson

All Theses And Dissertations

The American lobster, Homarus americanus, is an important consumer in the Gulf of Maine benthic community and supports the most valuable fishery in New England. Many fish predators that feed on juvenile lobster are found in the Gulf of Maine, but their abundance has varied over the previous decades. For example, striped bass, Morone saxatilis, have recovered from near extinction to become a viable recreational fishery on the east coast, and previous work examining the gut contents of striped bass found that juvenile lobsters were a large component of their diet during the summer in Massachusetts. However, striped …

Kitten Has Claws: The Feminine, The Feline, And The Threat Of The New Woman In Cecilia Beaux's "Sita And Sarita", Alexa Hayes

All ETDs from UAB

This thesis examines Cecilia Beaux's painting "Sita and Sarita" (1893-1894) as it expresses the conflicts of the women's rights movement, changing gender roles, and shifts in the perception of female sexuality and intellectualism in the late nineteenth century. The argument hinges on the quality of the woman's gaze and the anthropomorphic nature of the cat, which encompass growing interests in and fears of female mental capacity, sexuality, and animality. Examining how the portrait functions within three major traditions--depictions of young women in white dresses; women lost in thought or in reverie; and portraits of people with their pets, specifically women …
