The Sixty-Six Percent, Natalie Abruzzo
The Sixty-Six Percent, Natalie Abruzzo
Capstones
The Sixty-Six Percent represent the percentage of women in the U.S. who are overweight. They are regarded as full-figured or “plus” size in the world of women’s apparel. Even though more than half of American women wear a “plus” size - size 14 and up - designs for these women account for a fraction of women’s apparel - Only 37% of women's wear is plus-size.
The Sixty-Six Percent is coming at an important time in a broader conversation about de-stigmatizing what it means to be a plus-size woman in America. Fat shaming has become taboo and mainstream media as well …

Effects Of Melatonin On Heartbeat And Possible Identification Of A Melatonin Receptor In Drosophila Melanogaster, Tricia L. Vankirk
Electronic Theses and Dissertations
Chapter 1 of this manuscript is a literature review that serves as an introduction to the entire dissertation. Chapter 2 examines the effects of the melatonin injection on heart rate and rhythmicity in Drosophila melanogaster Canton-S (wild-type) pupae and pupae bearing a variety of heart mutations. Chapter 3 investigates further the possible mechanisms of melatonin’s ability to increase heart rhythmicity without significantly affecting heart rate. A melatonin antagonist, luzindole; a high-affinity melatonin agonist, 2-iodomelatonin and RNAi techniques are used to identify a possible melatonin receptor in Drosophila melanogaster.
An appendix contains a previously published manuscript detailing experiments performed at the …
Mechanisms Of Adaptation In The Newly Invasive Species Brachypodium Sylvaticum (Hudson) Beauv., Gina Lola Marchini
Mechanisms Of Adaptation In The Newly Invasive Species Brachypodium Sylvaticum (Hudson) Beauv., Gina Lola Marchini
Dissertations and Theses
It is common knowledge that invasive species cause worldwide ecological and economic damage, and are nearly impossible to eradicate. However, upon introduction to a novel environment, alien species should be the underdogs: They are present in small numbers, possess low genetic diversity, and have not adapted to the climate and competitors present in the new habitat. So, how are alien species able to invade an environment occupied by native species that have already adapted to the local environment? To discover some answers to this apparent paradox I conducted four ecological genetic studies that utilized the invasive species Brachypodium sylvaticum (Hudson) …

We have outlined a method for combining data mining with expert review to model the EHR process and develop automated algorithms that can be used to detect potential deviations for a defined process.
Introduction: To analyse EHR events meaningfully, process mining can be applied to distil structured process description from a set of real executions. Process mining can be applied for 1) Discovery, 2) Conformance, and …
Epacs: Epigenetic Regulators That Affect Cell Survival In Cancer., Catherine Murari
Epacs: Epigenetic Regulators That Affect Cell Survival In Cancer., Catherine Murari
Theses & Dissertations
Cyclic adenosine monophosphate (cAMP) is a second messenger responsive to many external stimuli, playing an important role in cellular gene expression, metabolism, migration, differentiation, hypertrophy, apoptosis and secretion. All of these cellular functions are important in many diseases including cancer. Most of its effects were initially attributed to the classical protein kinase A (PKA) protein, but cellular functions such as proliferation and migration were found to be PKA independent and dependent on the newly discovered exchange proteins directly activated by cAMP (EPACs). EPACs are single polypeptides that primarily function as guanine exchange factors (GEFs) for Rap proteins that allow the …
Interaction Between Angiotensin Ii And Bdnf In Modulating Sympathetic Nerve Activity, Bryan K. Becker
Interaction Between Angiotensin Ii And Bdnf In Modulating Sympathetic Nerve Activity, Bryan K. Becker
Theses & Dissertations
Over activation of the sympathetic nervous system is prevalent in many forms of cardiovascular disease such as chronic heart failure (CHF) and hypertension. Although increased neuronal renin-angiotensin system activity in presympathetic neurons has been well implicated in mediating this sympatho-excitation, many of the neuronal effects of angiotensin II (Ang II) signaling remain poorly understood. One particular mechanism of Ang II-mediated increases in presympathetic neuronal activity is through reductions in voltage-gated K+ currents. Another pathway that has profound effects on neuronal K+ currents and that has been previously implicated in Ang II-signaling is brain-derived neurotrophic factor (BDNF) activity through …
The Effect Of Body Mass Index On Graft Function And Kidney Transplant Outcomes, Morgan Galle
The Effect Of Body Mass Index On Graft Function And Kidney Transplant Outcomes, Morgan Galle
Theses & Dissertations
Background: When determining eligibility for kidney transplantation, body mass index (BMI) is often a debatable criterion for transplant due to the clinical indication, an elevated BMI has adverse effects on kidney transplant outcomes. There is a current gap in research on the effect BMI has on kidney transplant outcomes.
Purpose: The purpose of this study was to determine the role BMI plays in post-kidney transplant clinical outcomes including delayed graft function, new onset diabetes after transplant, wound complications, hospital length of stay, albumin, and readmissions to the hospital from initial hospitalization and at six months following kidney transplantation. The primary …
The Feedforward And Feedback Controls On Gait In Adults With Diabetes, Chun-Kai Huang
The Feedforward And Feedback Controls On Gait In Adults With Diabetes, Chun-Kai Huang
Theses & Dissertations
There are nearly 26 million people with diabetes mellitus (DM) in the US, and half of chronic DMs develop somatosensory deficits due to diabetic polyneuropathy or diabetic peripheral neuropathy (DPN). The absence or impaired somatosensory feedback (e.g. touch sensation or joint proprioception) resulted from the damage of large nerve fiber, and motor deficits such as attenuated muscle strength and abnormal plantar pressure of lower extremity have been identified in DPN, and these sensorimotor impairments lead to an increased number of falls. To reduce the risk of falling, a well-coordinated and adapted limb movement driven by the feedforward (anticipatory) and feedback …
The Role Of Bone Sialoprotein In Periodontal Tissue Development And Bone Repair, Yohannes Soenjaya
The Role Of Bone Sialoprotein In Periodontal Tissue Development And Bone Repair, Yohannes Soenjaya
Electronic Thesis and Dissertation Repository
Bone development and repair involve complex processes that include interaction between cells and their surrounding matrix. In the body, bone sialoprotein (BSP) expression is up-regulated at the onset of mineralization. BSP is a multifunctional acidic phosphoprotein with collagen-binding, hydroxyapatite nucleating, and integrin recognition (RGD sequence, which is important for cell-attachment and signaling) regions. Mice lacking BSP expression (Bsp-/-), exhibit a bone phenotype with reductions in bone mineral density, bone length, osteoclast activation, and impaired bone healing. This thesis examined the role of BSP in tooth development and also its potential use as a therapeutic reagent for bone …
Serotonergic System And Gait: Dorsal Raphe Nucleus As A Control System For Gait, Nahal Farhani
Serotonergic System And Gait: Dorsal Raphe Nucleus As A Control System For Gait, Nahal Farhani
Electronic Thesis and Dissertation Repository
In advanced stages of Parkinson Disease (PD), gait and postural abnormalities emerge. These symptoms are not prominent at early stages of PD despite significant dopaminergic neuronal loss. Gait abnormalities are largely not responsive to levodopa. Therefore, other types of neurons might be responsible for gait abnormalities of the PD.
Since the reticulospinal tract (RET) is mainly implicated in the control of axial muscles, the degeneration of this pathway or populations of neurons controlling this pathway might be responsible for axial symptoms. However, there is limited data about the neurons controlling the RET. Our aim in this study is to delineate …
Is Dexamethasone 4mg A More Effective Anti-Emetic Than Dexamethasone 8mg For The Prevention Of Early Post-Operative Nausea And Vomiting In Women Undergoing Laparoscopic Gynecological Surgery?, Steven B. Doyle
Doctoral Projects
Postoperative nausea and vomiting (PONV) is a common problem in the surgical setting. It affects as much as 20 to 80 percent of patients undergoing surgery (D'souza, Swami, & Bhagwat, 2011). PONV can lead to increased patient costs and recovery time by causing the patient to stay in the healthcare facility for a longer period of time. A retrospective cohort study was completed to examine whether or not there was a significant difference between patients who received 4mg and 8mg of dexamethasone in the incidence of PONV. All patients studied received ondansetron intraoperatively as their primary anti-emetic. English speaking patients …
The Effectiveness Of A Preoperative Multimodal Antiemetic Regimen On Reducing Early Postoperative Nausea And Vomiting In Total Joint Arthroplasty Patients, Jerry Mosley
Doctoral Projects
Postoperative nausea and vomiting (PONV) occurs frequently in all types of surgeries including after total joint orthopedic procedures. The resulting PONV can lead to many unwanted occurrences including immobilization, distress, and many serious adverse health complications. These unwanted occurrences may then lead to increased cost to the patient and healthcare facility. Administration of a preoperative multimodal regimen known to reduce PONV has the potential to reduce such unwanted anesthetic side effects influencing a reduction in overall healthcare cost. The purpose of this study is to determine the effectiveness of the preoperative kit which includes the administration of metoclopramide, famotidine, ondansetron, …
Evidence For Using Immunosuppressive Treatments When Treating Idiopathic Non-Infectious Uveitis: A Systematic Review And Meta-Analysis, Hargurinder Singh
Evidence For Using Immunosuppressive Treatments When Treating Idiopathic Non-Infectious Uveitis: A Systematic Review And Meta-Analysis, Hargurinder Singh
Electronic Thesis and Dissertation Repository
Idiopathic non-infectious uveitis is the spontaneous inflammation of the eye, which can lead to blindness if not treated correctly. Due to long-term side effects of corticosteroids, 4 classes of off-label immunosuppressive treatments are sometimes used (alkylating agents, inhibitors of T-lymphocyte signalling, antimetabolites and biological modifiers). We conducted a systematic review and meta-analysis to assess the effectiveness of different treatment classes on uveitis patients with similar characteristics. Results of the systematic review concurred with the conclusions from the meta-analysis, which found that all immunosuppressive treatments improved patient vision, with a statistically significant change in logMAR of -0.11 (95% CI of -0.152 …

This information was then used to compare the microbial phyla between both groups for any differences. Total microbial DNA was isolated from each fecal sample, and the 16S rRNA gene was sequenced using Illumina MiSeq high throughput method. The sequences were identified using the bioinformatics program mothur. The results show that indoor cats had a more diverse microbial community as compared to outdoor cats. Indoor cat samples had 26% more microbial species, and eight more …
Design And Testing Of Novel Anthrax Vaccines Utilizing A Tobacco Mosaic Virus Expression System, Ryan C. Mccomb
Design And Testing Of Novel Anthrax Vaccines Utilizing A Tobacco Mosaic Virus Expression System, Ryan C. Mccomb
KGI Theses and Dissertations
Anthrax is a potentially fatal disease caused by the bacteria Bacillus anthracis. Infection and disease occur after spores gain entry into the body, germinate into vegetative bacteria, and produce toxin. Bacillus anthracis spores have been engineered as bioweapons and have been used repeatedly in warfare and terrorism to inflict casualties in military and civilian populations. Currently, only one vaccine has been approved for prevention of anthrax in the United States. This vaccine is an undefined product that is difficult to produce, requires a long vaccination schedule, and is reactogenic. Efforts to make an improved anthrax vaccine are being pursued. …
Health Assessment Of Two Reintroduced Populations Of American Martens (Martes Americana) In Michigan, Maria Catherine Spriggs
Health Assessment Of Two Reintroduced Populations Of American Martens (Martes Americana) In Michigan, Maria Catherine Spriggs
Doctoral Dissertations
The American marten (Martes americana) was extirpated from Michigan during the early-20th century due to loss of vast areas of mature conifer forest and unregulated trapping. The species was reintroduced into the Upper Peninsula (UP) and Northern Lower Peninsula (NLP) during the mid-20th century. While the American marten population in the UP has grown and is doing well, the population in the NLP has been less successful. The reasons for the limited success of the NLP population are unknown, but may include lack of suitable habitat, limited reproductive success, poor genetic diversity, disease, or negative environmental impacts. American …
Brown And Beige Adipocytes: Effects Of Inflammation And Nutritional Intervention, Jiyoung Bae
Brown And Beige Adipocytes: Effects Of Inflammation And Nutritional Intervention, Jiyoung Bae
Doctoral Dissertations
Recent findings of brown adipocytes and brown-like or beige adipocytes, capable of dissipating energy as heat, in adult humans have promised new hope for obesity treatment and prevention. Understanding of the regulation of brown and beige adipocytes will provide novel strategies to reach the goal. Pattern recognition receptors (PRR) are responsible for inflammation in adipose tissue, which leads to adipose dysfunction and obesity associated chronic diseases. It has been shown that PRR activation induces inflammation, leading to insulin resistance in white adipocytes and white adipose tissue (WAT). However, the roles of PRR activation in brown adipocytes and brown adipose tissue …
Epidemiology Of Select Species Of Filarial Nematodes In Free-Ranging Moose (Alces Alces) Of North America, Caroline Mae Grunenwald
Epidemiology Of Select Species Of Filarial Nematodes In Free-Ranging Moose (Alces Alces) Of North America, Caroline Mae Grunenwald
Doctoral Dissertations
North American moose (Alces alces) are a culturally and economically valued species. Recent population declines raise concern for the survivability of this natural resource. The Minnesota population has experienced the most dramatic decline, with a 60% loss in total numbers since 2006. Nematode parasites, particularly some species of filarids, are important pathogens of moose and could be contributing to morbidity and mortality. This study investigates the eco-epidemiology of two filarial parasites of moose: Rumenfilaria andersoni and Elaeophora schneideri. By surveying cervid species from six U.S. states, we discovered R. andersoni was present in moose from all sample locations …
Determining The Mechanisms Generating Soluble Il-15 Complexes, Scott Anthony
Determining The Mechanisms Generating Soluble Il-15 Complexes, Scott Anthony
Dissertations & Theses (Open Access)
A diverse assortment of infectious pathogens and TLR agonists enhance the expression of Interleukin (IL)-15. Additionally, inducing lymphopenia enhances anti-tumor responses in an IL-15-dependent manner. Paradoxically, despite the limited expression of IL-15 during homeostasis, the role of IL-15 during the steady state is well-known, while its roles during inflammation and infections remain largely undefined. IL-15 uses a unique method of production and presentation to support the development and homeostasis of NK and CD8 T cells. IL-15 is produced with its high affinity IL-15Rα and this IL-15Rα/IL-15 complex is shuttled to the cell surface where it is presented in-trans or cleaved …
Role Of Stat3 In Human Nk Cell Functions, Prasad V. Phatarpekar
Role Of Stat3 In Human Nk Cell Functions, Prasad V. Phatarpekar
Dissertations & Theses (Open Access)
Natural Killer (NK) cells are cytotoxic lymphocytes, which play a critical role in the immune response against malignant cells and microbial infections. NK cells are equipped with activating receptors, which upon detecting ligands expressed on stressed cells induce cytolytic activity of NK cells. Stimulation of NK cell proliferation and priming of NK cytolytic capability are accomplished by cytokines, which mediate their signals mainly through JAK-STAT signaling pathway. Previously, we found that K562 cells genetically modified to express membrane bound IL-21 (mbIL-21), which predominantly activates STAT3, induce robust expansion and activation of human NK cells. Further investigations revealed role of STAT3 …
Scardovia Wiggsiae Prevalence In Orthodontic Patients, Brandon Joseph Streiff
Scardovia Wiggsiae Prevalence In Orthodontic Patients, Brandon Joseph Streiff
UNLV Theses, Dissertations, Professional Papers, and Capstones
Dental caries has mainly been associated with Streptococcus, Lactobacillus, Actinomyces and Veillonella species. But in recent salivary studies a new cariogenic pathogen, has been identified. This new bacteria, Scardovia wiggsiae (SW), is currently being tested within the UNLV School of Dental Medicine patient population. Although these current studies are being conducted to study its prevalence in both pediatric and adult populations, it has not been evaluated among patients with an altered oral environment as seen in patients with orthodontic appliances. Fixed orthodontic appliances increase the difficulty of removing daily plaque on and in between the teeth with standard oral hygiene …

Hospital Practices Related To Breastfeeding In Mississippi: A Socio-Ecological Approach, Amir Alakaam
Dissertations
Mississippi continues to have one of the lowest rates and the weakest support in respect to breastfeeding in the nation (Centers for Disease Control and Prevention, 2014a). Hospital practices supporting breastfeeding such as the Ten Steps to Successful Breastfeeding (TSSB) can dramatically increase breastfeeding rates and duration (Rosenberg, Stull, Adler, Kasehagen, & Crivelli-Kovach, 2008). The aim of this study was to explore breastfeeding practices in Mississippi hospitals based on two levels of the Socio-Ecological Model: the organizational level (phase I) examined the hospital practices based on the level of implementation of the TSSB; the individual level (phase II) examined knowledge …
Identifying Protein Kinase Tbk1 As A Novel Inhibitor Of Intestinal Tumorigenesis, Amber L. Mathews
Identifying Protein Kinase Tbk1 As A Novel Inhibitor Of Intestinal Tumorigenesis, Amber L. Mathews
Dissertations & Theses (Open Access)
Colorectal cancer (CRC) is the third most common cancer diagnosed in women and men, causing almost 600,000 annual deaths worldwide. There is a clear need to understand how CRC forms and progresses in order to improve the strategies of CRC prevention and therapy. A major factor that drives the development of CRC is genetic mutations that lead to activation of oncogenes and inactivation of tumor suppressor genes in intestinal epithelial cells (IECs). In addition, the initiation and progression of CRC involve environmental and immunological factors. In particular, chronic inflammatory conditions are known as an important risk factor for CRC. Intestinal …

The Tumor Suppressor Notch Inhibits Head And Neck Squamous Cell Carcinoma (Hnscc) Tumor Growth And Progression By Modulating Proto-Oncogenes Axl And Ctnnal1 (Α-Catulin), Shhyam Moorthy, Shhyam Moorthy
Dissertations & Theses (Open Access)
Background: Head and Neck Squamous Cell Carcinoma (HNSCC) is the sixth most common malignancy worldwide, with roughly 300,000 cancer related deaths occurring globally each year. The survival of patients with HNSCC has not changed significantly over the past decade, leading investigators to search for promising molecular targets. To identify new treatment targets and biomarkers that could better guide therapy, we previously characterized the genomic alterations from primary HNSCC patient samples. We were among the first to discover that NOTCH1 is one of the most frequently mutated genes in this cancer type. The spectrum of inactivating NOTCH1 mutations in HNSCC suggested …
Upper Extremity Kinematic And Kinetic Comparison Of Anterior Versus Posterior Walkers During Functional Activities In Children With Cerebral Palsy, Chris Burckardt
Upper Extremity Kinematic And Kinetic Comparison Of Anterior Versus Posterior Walkers During Functional Activities In Children With Cerebral Palsy, Chris Burckardt
Theses and Dissertations
Introduction: Investigating the differences in upper extremity (UE) joint biomechanics between anterior and posterior walkers has been explored in limited contexts, even though research has shown that prolonged use of walking aids can lead to UE joint weakening or musculoskeletal injuries. Recent studies have investigated some of these differences in children with spastic diplegic cerebral palsy (CP) during gait; however, no research has been conducted that compare these UE joint biomechanical differences during functional activities or activities of daily living (ADLs). The aim of this study is to use motion analysis to compare kinematic and kinetic differences between anterior and …
Activation Of Microglia In The Rotenone Lymnaea Stagnalis Model Of Parkinson's Disease, Xiomara Galvan
Activation Of Microglia In The Rotenone Lymnaea Stagnalis Model Of Parkinson's Disease, Xiomara Galvan
Theses and Dissertations
Parkinson’s disease (PD) is the most common irreversible neurodegenerative movement disorder affecting approximately ten million people worldwide. In the central nervous system (CNS), PD is known by the selective loss of Dopamine (DA) cells of the substantia nigra pars compacta. Although the disease has been very widely studied, the underlying mechanisms are not yet understood. Several hypotheses have arisen as result of injury of the mitochondria, some experiments include microglia activation, microtubule damage, and reactive oxidative species, which all result in the death of DA cells. The theory of microglia activation upon inflammation was explored in this study. Using the …
Educated Birth: Beliefs Vs. Outcomes, Lauren Presley
Educated Birth: Beliefs Vs. Outcomes, Lauren Presley
Human Nutrition and Hospitality Management Undergraduate Honors Theses
“Our infant mortality rate is a national embarrassment.”1 The words seem shocking and harsh across the headline of a 2014 Washington Post article. The thought of America not only not being the best at something, but falling upsettingly behind, is a foreign concept to many who view America as a nation inferior to none. However, the statistics on infant mortality rate tell the stark truth that of 26 “wealthy” countries, the U.S. ranks last, with a sobering 6.1 deaths per 1,000 live infant births.2
Part of the Healthy People 2020 Objectives is to reduce the rate of infant …
Mobilization Of Adipose Stromal Cells In Obesity And Cancer By Sparc And Its Proteolytic Isoforms, Chieh Tseng
Mobilization Of Adipose Stromal Cells In Obesity And Cancer By Sparc And Its Proteolytic Isoforms, Chieh Tseng
Dissertations & Theses (Open Access)
Obesity increases cancer risk and progression as shown by epidemiologic studies. However, the underlying pathophysiology remained unclear. Adipose stromal cells (ASC) are adipose tissue-derived mesenchymal progenitors, abundant in white adipose tissue (WAT). In this study, we show that the ASC pool is expanded in obesity and is associated with promoted tumor growth. Next, by using a chimeric GFP-RFP bone marrow transplant model, we observed higher tumor infiltrating cells with ASC phenotype in obese mice compared to lean. Consistently, systemic circulating ASC frequency is six fold higher in tumor-bearing obese mice compared to lean. The tumor infiltrating cells with ASC phenotype …

In Vivo Functional Significance Of Ccat2 Long Non-Coding Rna In Myelodysplastic Syndrome, Maitri Y. Shah
Dissertations & Theses (Open Access)
Long non-coding RNAs form the largest part of the mammalian non-coding transcriptome and control gene expression at various levels including chromatin modification, transcriptional and post-transcriptional processing. Although the underlying molecular mechanisms are not yet entirely understood, lncRNAs are implicated in initiation and progression of several cancers. CCAT2 is a lncRNA that spans the highly conserved 8q24 region associated with increased risk for various cancers. CCAT2 has been shown to play an important role in inducing chromosomal instability and supporting cell proliferation and cell cycle arrest. However, a causal role of CCAT2 in initiation of tumorigenesis and the importance of G/T …
