A Century Of Morphological Variation In Cyprinidae Fishes, Stephen J. Jacquemin, Mark Pyron

Biological Sciences Faculty Publications

Background

Aquatic habitats have been altered over the past century due to a variety of anthropogenic influences. Ecomorphology is an area of aquatic ecology that can both directly and indirectly assess the effects of habitat alterations on organisms. However, few studies have explored long term trends in morphological variation. Long term changes in morphology can potentially impact niche and ultimately contribute to organismal success and the ecosystem. Therefore, in this study we assessed long term morphological variation with body size, sex, time, and hydrology using museum collections of five species of Cyprinidae (Minnows) from lentic and lotic systems over the …

Nearly twenty to thirty percent of those will experience chronic cognitive, behavioral and somatic symptoms after suffering a TBI.
Methods: The objective of this review is to evaluate current literature examining vitamin D as a neurosteroid with protective properties and its clinical relevance after traumatic brain injury. Vitamin D is known to participate in neurobiological …

Medical Interns', Residents' And Attending Physicians' Attitudes Towards Integrative Medicine And Recommended Treatments For Patients With Psoriasis, Jennifer L. Pacyon

PCOM Psychology Dissertations

Background: Psoriasis is a multifactorial disease that effect approximately 7.5 million Americans. There are a variety of traditional treatments for psoriasis (e.g. topical medications, biologics) that for many, are effective in combating the disease. However, traditional treatments often have aversive side effects and may not be appropriate for every patient (e.g. pregnant women). Additionally, the efficacy of these medications are variable leaving some looking for adjunctive treatment options. There is increasing evidence to support the use of adjunctive treatments for psoriatic patients (e.g. psychotherapy, mindfulness). However, research is variable in regards to medical professionals’ attitudes towards integrative medicine (IM) as …

Structural And Functional Characterization Of Enzymes Of A Novel Group Of Tryptophylquinone Cofactor Containing Oxidases, Esha Sehanobish

Electronic Theses and Dissertations

Protein-derived cofactors are redox and catalytic centers that are generally formed by the posttranslational modifications of one or more amino acids. An important class of these cofactors are the quinones derived from tyrosine and tryptophan. Amongst redox proteins, it has been known till now that oxidases either contain a flavin or a tyrosylquinone cofactor, whereas tryptophylquinone ones are present within the dehydrogenases. In recent times, oxidases from a marine bacterium, Marinomonas mediterranea, have been shown to possess the latter. This study involves the characterization of two such proteins, lysine-?-oxidase (LodA) and glycine oxidase (GoxA). They have been reported to contain …

Identification And Characterization Of Dna Repair Snf2/Swi2 Atpases In Tetrahymena Thermophila, Andrew Francis Morin

Graduate Theses/Dissertations

The Snf2/Swi2 ATPases Rad5 and Rad16 have been shown to play vital roles in a number of DNA repair pathways. In both Saccharomyces cerevisiae and human cell lines, Rad5 homologs (SHPRH, HLTF) have been shown to function in DNA double strand break (DSB) repair along with pathways that repair damage after replication. The function of Rad16, unlike Rad5, has been found only in lower eukaryotes such as Saccharomyces, despite the fact that it plays an essential role in nucleotide excision repair (NER), and more specifically in the repair of silenced areas of the genome. In order to more fully understand …

Methods:

MALDI-TOF (Bruker) analysis with sepsityper extraction (aerobic Gram-positive and anaerobic bacteria); MALDI-TOF analysis with serum separator tube concentration (Gram-negative bacteria); and a FilmArray Blood Culture Panel (Biofire) were utilized. MALDI was …

Expression Levels Of Virulence Genes In Group A Streptococci: A Response To Aerosolized Propylene Glycol, Michael S. Costello

Honors Undergraduate Theses

Electronic cigarette usage is becoming increasingly prevalent among school age children and young adults. A known bactericidal agent, propylene glycol, is often used as a carrier for nicotine, flavoring, and additional constituents of electronic cigarette juice. This study examined the relationship between propylene glycol and virulence gene expression in Streptococcus pyogenes, a respiratory tract pathogen commonly found in school-age individuals. A variety of virulence genes controlled by the three stand alone regulators mga, RofA, and Rgg/RopB were sampled in an effort to understand the pathway by which virulence is affected. The genes chosen encode C5a peptidase, fibronectin binding protein, hyaluronate …

Chronic Pancreatitis, Pain, And Anxiety In An Alcohol And High Fat Mouse Model, Tiffanie Clinkinbeard

Theses and Dissertations--Gerontology

Homeodynamic space (HDS) shrinks as vulnerability increases with aging and repeated damage to the cells. HDS is lost in alcoholic pancreatitis patients due to overconsumption of alcohol, smoking, and high fat diets. Etiologically relevant animal models for study of chronic pancreatitis (CP) are needed. In order to begin filling this gap a central purpose of this dissertation research was to examine relationships between the alcohol and high fat diet (AHF) and pancreatitis with attention to hypersensitivity and anxiety-like behaviors. The AHF diet induced pancreatitis described here etiologically mimics human risk factors of AHF consumption for advancement to alcoholic CP.

Molecular Genetics Of Ms4a6a And Alzheimer's Disease, Ryan Harpole

Lewis Honors College Capstone Collection

Increased Alzheimer’s disease (AD) risk has previously been associated with a SNP called rs610932 near the gene MS4A6A. The goal of this experiment was to quantify the expression of two MS4A6A isoforms in the brains of AD and non-AD subjects, particularly as a function of rs610932 genotype. According to an article titled “Alzheimer’s Disease Susceptibility Variants in the MS4A6A Gene are Associated with Altered Levels of MS4A6A Expression in Blood”, MS4A6A has four different isoforms that have been reported to be differentially expressed in the blood of AD subjects compared to non-AD subjects (Petroula et al., 2014). After statistically …

The field of tissue engineering is developing biomimetic biomaterial scaffolds which are showing increasing therapeutic potential for the repair of cardiovascular tissues. However, a major opportunity exists to use them as 3D in vitro models for the study of cardiovascular tissues and disease in addition to drug development and testing. These in vitro models can span the gap between 2D culture and in vivo testing thus reducing cost, time and the ethical burden of current approaches. This review outlines the progress to date and requirements for the development of ideal in vitro 3D models for blood vessels, heart valves and …

Il-15 Mediates Mitochondrial Activity Through A Ppar𝛿-Dependent-Ppar𝛼-Independent Mechanism In Skeletal Muscle Cells, Shantaé M. Thornton, James E. Krolopp, Marcia J. Abbott

Health Sciences and Kinesiology Faculty Articles

Molecular mediators of metabolic processes, to increase energy expenditure, have become a focus for therapies of obesity. The discovery of cytokines secreted from the skeletal muscle (SKM), termed “myokines,” has garnered attention due to their positive effects on metabolic processes. Interleukin-15 (IL-15) is a myokine that has numerous positive metabolic effects and is linked to the PPAR family of mitochondrial regulators. Here, we aimed to determine the importance of PPAR𝛼 and/or PPAR𝛿 as targets of IL-15 signaling. C2C12 SKM cells were differentiated for 6 days and treated every other day with IL-15 (100 ng/mL), a PPAR𝛼 inhibitor (GW-6471), a PPAR𝛿 …

Limited Trabecular Bone Density Heterogeneity In The Human Skeleton, Habiba Chirchir Phd

Biological Sciences Faculty Research

There is evidence for variation in trabecular bone density and volume within an individual skeleton, albeit in a few anatomical sites, which is partly dependent on mechanical loading. However, little is known regarding the basic variation in trabecular bone density throughout the skeleton in healthy human adults. This is because research on bone density has been confined to a few skeletal elements, which can be readily measured using available imaging technology particularly in clinical settings. This study comprehensively investigates the distribution of trabecular bone density within the human skeleton in nine skeletal sites (femur, proximal and distal tibia, third metatarsal, …

Consequences Of Estrogen Receptor Beta Phosphorylation In The Aged Female Brain And Heart, Elena Pinceti

Dissertations

Female life expectancy in the United States has steadily increased and now averages 81 years. Meanwhile, the age at which women reach menopause remains constant at 51 years. Both neurological and cardiovascular disorders increase following menopause, affecting women’s quality of life and leading to large health care costs. Estrogens are neuroprotective and cardioprotective for women, however when administered long after menopause, they fail to improve their health.

The effects of estrogen are mediated by Estrogen Receptor α (ERα) and Estrogen Receptor β (ERβ). Evidence supports that ERβ plays an important role in neuroprotection and cardioprotection, but aspects of ERβ molecular …

Giant Chloroviruses: Five Easy Questions, James L. Van Etten, David Dunigan

Nebraska Center for Virology: Faculty Publications

Chloroviruses are large, icosahedral, dsDNA-containing viruses that replicate in certain unicellular, chlorella-like green algae [1,2]. They exist in freshwater throughout the world with titers as high as thousands of plaque-forming units (PFU) per ml of indigenous water although titers are typically 1–100 PFU/ml. Titers fluctuate during the year with the highest titers typically occurring in the spring and late fall. Known chlorovirus hosts, which are normally symbionts and are often referred to as zoochlorellae, are associated with either the protozoan Paramecium bursaria (Fig 1A), the coelenterate Hydra viridis, or the heliozoan Acanthocystis turfacea. Zoochlorellae are resistant to viruses …

The aim of this study was to analyze the impact of genetic variability on the genetic barrier to drug resistance to DAAs.

Methods: The genetic barrier was quantified based on the number and type of nucleotide mutations required to impart resistance, considering full-length HCV NS3, NS5A and NS5B regions segregated by genotype into subtypes 1a, 1b, 2a, 2b and 3a. This study analyzed 789 NS3 sequences, 708 sequences and 536 NS5B …

Kaposi’S Sarcoma-Associated Herpesvirus Reduces Cellular Myeloid Differentiation Primary-Response Gene 88 (Myd88) Expression Via Modulation Of Its Rna, Amy Lingel, Erica Ehlers, Qianli Wang, Mingxia Cao, Charles Wood, Rongtuan Lin, Luwen Zhang

Nebraska Center for Virology: Faculty Publications

Kaposi’s sarcoma (KS)-associated herpesvirus (KSHV) is a human gammaherpesvirus associated with several human malignancies. The replication and transcription activator (RTA) is necessary and sufficient for the switch from KSHV latency to lytic replication. Interleukin 1 (IL-1) is a major mediator for inflammation and plays an important role in both innate and adaptive immunity. Myeloid differentiation primary response gene 88 (MyD88) is an essential adaptor molecule for IL-1 as well as most Toll-like receptor signaling. In this study, we identified a novel mechanism by which KSHV interferes with host inflammation and immunity. KSHV RTA specifically reduces the steady-state protein levels of …

Nf45 And Nf90 Bind Hiv-1 Rna And Modulate Hiv Gene Expression, Yan Li, Michael Belshan

Nebraska Center for Virology: Faculty Publications

A previous proteomic screen in our laboratory identified nuclear factor 45 (NF45) and nuclear factor 90 (NF90) as potential cellular factors involved in human immunodeficiency virus type 1 (HIV-1) replication. Both are RNA binding proteins that regulate gene expression; and NF90 has been shown to regulate the expression of cyclin T1 which is required for Tat-dependent trans-activation of viral gene expression. In this study the roles of NF45 and NF90 in HIV replication were investigated through overexpression studies. Ectopic expression of either factor potentiated HIV infection, gene expression, and virus production. Deletion of the RNA binding domains of NF45 …

Mucosal Vaccination By Adenoviruses Displaying Reovirus Sigma 1, Eric A. Weaver, Zenaido T. Camacho, Matthew L. Hillestad, Catherine M. Crosby, Mallory A. Turner, Adam J. Guenzel, Hind J. Fadel, George T. Mercier, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

We previously developed adenovirus serotype 5 (Ad5) vectors displaying the sigma 1 protein from reovirus as mucosal vaccines. Ad5-sigma retargets to JAM-1 and sialic acid, but had 40-fold reduced gene delivery when compared to Ad5. While weaker at transduction, Ad5-sigma generated stronger T cell responses than Ad5 when used for mucosal immunization. New Ad5- fiber-sigma vectors were generated here by varying the number of fiber β-spiral shaft repeats (R) fused between fiber tail and the sigma. Ad5 virions encoding R3, R14, and R20 chimeras were rescued. Increasing chimera length led to their decreasing encapsidation of these proteins in the virions. …

Pathology and Cell Biology Faculty Publications

The role of cutaneous human papillomavirus (HPV) infection in the development of subsequent cutaneous squamous cell carcinoma (SCC) is unknown. Pathologically confirmed cases of SCC () enrolled in a previously conducted case-control study were included in a retrospective cohort study to examine the association of cutaneous HPV at the time of SCC diagnosis with the risk of subsequent SCC development. Data on HPV seropositivity, HPV DNA in eyebrow hairs (EB) and SCC tumors were available from the parent study. Incidence of subsequent SCC was estimated using person-years of follow up. Cox Proportional Hazards ratios were estimated to evaluate the associations …

Assessing Cultural Competence In Nursing Students At A Small Private Liberal Arts University, Mikah K. Barrueta Ms

Undergraduate Honors Thesis Projects

Appropriate care across cultures can occur only when patient, family, and community expectations are aligned with provider knowledge, attitude, and behavior (Doorenbos et al, 2005). Because nurses treat patients from all types of backgrounds, a culturally competent approach should and must be used when educating and training future nurses. The purpose of this study is to assess various cultural competence components of senior nursing students at a small Midwestern University. In order to assess this sample population, two peer-reviewed surveys were chosen; the Quality and Culture Quiz and the Affective Racial Attitudes subscale from the Quick Discrimination Index. Three more …

Uvb Generates Microvesicle Particles Via Platelet-Activating Factor-Receptor Signaling: A Novel Pathway By Which A Skin-Specific Stimulus Exerts Systemic Effects, Jeffrey B. Travers, Christine M. Rapp, Katherine E. Fahy, Christina E. Borchers, Richard Simman, Langni Liu, Yanfang Chen, Ji C. Bihl

Pharmacology and Toxicology Faculty Publications

Though Ultraviolet B radiation (290-320 nm; UVB) exerts profound systemic effects, it is absorbed only in the epidermis. One important question in photobiology is how UVB signals are emanated from the epidermis. Microvesicle particles (MVP) are small (200-1000nm diameter) membrane-bound vesicles released by numerous cell types and can be found in the circulation. MVP can contain both nuclear and cytoplasmic components and are thought to provide a mechanism by which cells transmit signals systemically. Though various stressors have been demonstrated to generate MVP, the ability of UVB to exert this effect has not been demonstrated. Previous studies from ours and …

The Novel Methods For Analysis Of Exosomes Released From Endothelial Cells And Endothelial Progenitor Cells, Jinju Wang, Runmin Guo, Yi Yang, Bradley S. Jacobs, Suhong Chen, Ifeanyi Iwuchukwu, Kenneth J. Gaines, Yanfang Chen, Richard Simman, Guiyuan Lv, Keng Wu, Ji C. Bihl

Pharmacology and Toxicology Faculty Publications

Exosomes (EXs) are cell-derived vesicles that mediate cell-cell communication and could serve as biomarkers. Here we described novel methods for purification and phenotyping of EXs released from endothelial cells (ECs) and endothelial progenitor cells (EPCs) by combining microbeads and fluorescence quantum dots (Q-dots®) techniques. EXs from the culture medium of ECs and EPCs were isolated and detected with cell-specific antibody conjugated microbeads and second antibody conjugated Q-dots by using nanoparticle tracking analysis (NTA) system. The sensitivities of the cell origin markers for ECs (CD105, CD144) and EPCs (CD34, KDR) were evaluated. The sensitivity and specificity were determined by using positive …

Potential Treatments For Malformation Associated Epilepsy, Olivia M. Bowles

Theses and Dissertations

Epilepsy has been previously attributed to either increased excitation or decreased inhibition. With this closed frame of mind, modern medicine has been unable to develop a permanent treatment against the mechanisms of epilepsy. In order to treat patients with intractable seizures, especially those caused by developmental malformations, it is essential to understand the entirety of mechanisms that could possibly play a role in the abnormal cortical function. One such developmental malformation is known as polymicrogyria. Epileptogenesis occurs in an area laterally adjacent to this malformation known as the paramicrogyral region (PMR). Past studies have narrowed down the potential cause of …

Power Analysis In Applied Linear Regression For Cell Type-Specific Differential Expression Detection, Edmund Glass

Theses and Dissertations

The goal of many human disease-oriented studies is to detect molecular mechanisms different between healthy controls and patients. Yet, commonly used gene expression measurements from any tissues suffer from variability of cell composition. This variability hinders the detection of differentially expressed genes and is often ignored. However, this variability may actually be advantageous, as heterogeneous gene expression measurements coupled with cell counts may provide deeper insights into the gene expression differences on the cell type-specific level. Published computational methods use linear regression to estimate cell type-specific differential expression. Yet, they do not consider many artifacts hidden in high-dimensional gene expression …

Novel Cellular Targets Of Aspirin In Chemoprevention Studies On P53, G6pd And C-Myc, Guoqiang Ai

Electronic Theses and Dissertations

Background

Aspirin has generated a significant interest in recent years as a potential chemopreventive agent supported by strong evidence from epidemiological data; however, the mechanisms are not well understood. The objective of this dissertation is to identify novel cyclooxygenase (COX)-independent pathways by which aspirin exerts its anticancer effects in epithelial cancer cell lines. We investigated the effect of aspirin on p53, glucose 6-phosphate dehydrogenase (G6PD), and c-Myc, all of which are known to play a major role in cancer development. p53 is a tumor suppressor protein, often mutated in cancers causing its inactivation. Expression of G6PD is elevated in many …

Bisphenol-A And Sleep Adequacy Among Adults In The National Health And Nutrition Examination Surveys, Hind A. Beydoun, May A. Beydoun, Hueiwang Anna Jeng, Alan B. Zonderman, Shaker M. Eid

Community & Environmental Health Faculty Publications

Study Objectives: To evaluate bisphenol-A (BPA) level and its relationship to sleep adequacy in a nationally representative sample of U.S. adults.
Methods: A population-based cross-sectional study was conducted using 2005-2010 National Health and Nutrition Examination Survey whereby data were collected using in-person interviews, physical examination and laboratory testing. BPA level was measured in urine samples and analyzed as loge-transformed variable and in quartiles (< 0.9 ng/mL; 0.9 to < 1.9 ng/mL; 1.9 to < 3.7 ng/mL; 3.7+ ng/mL). Sleep adequacy was operationalized with three questions: "How much sleep do you usually get at night on weekdays or workdays?", "Have you ever told a doctor or other health professionals that you have trouble sleeping?" and "Have you ever been told by a doctor or other health professional that you have a sleep disorder?" Sleep duration was further categorized as (< 6 h, ≥ 6 h); (< 7 h, 7-8 h, > 8 h); (< 5 h, 5-6 h, 7-8 h, ≥ 9 h). Linear, binary, and ordinal logistic regression models were constructed.
Results: Loge-transformed BPA level was inversely related to sleep duration defined, in hours, as a continuous variable, a dichotomous variable (≥ 6, < 6), or an ordinal variable (≥ 9, 7-8, 5-6, < 5), after adjustment for confounders. Help-seeking behavior for sleep problems and diagnosis with sleep disorders were not significantly associated with loge-transformed BPA level in fully adjusted models.
Conclusions: Loge-transformed BPA level may be associated with fewer hours of …

A Dielectric Rod Antenna For Picosecond Pulse Stimulation Of Neurological Tissue, Ross A. Petrella, Karl H. Schoenbach, Shu Xiao

Bioelectrics Publications

A dielectrically loaded wideband rod antenna has been studied as a pulse delivery system to subcutaneous tissues. Simulation results applying 100-ps electrical pulse show that it allows us to generate a critical electric field for biological effects, such as brain stimulation, in the range of several centimeters. In order to reach the critical electric field for biological effects, which is similar to 20 kV/cm, at a depth of 2 cm, the input voltage needs to be 175 kV. The electric field spot size in the brain at this position is similar to 1 cm(2). Experimental studies in free space with …

Large Genomic Differences Between Moraxella Bovoculi Isolates Acquired From The Eyes Of Cattle With Infectious Bovine Keratoconjunctivitis Versus The Deep Nasopharynx Of Asymptomatic Cattle, Aaron M. Dickey, John D. Loy, James L. Bono, Timonthy P. L. Smith, Mike D. Apley, Brian V. Lubbers, Keith D. Dedonder, Sarah F. Capik, Robert L. Larson, Brad J. White, Jochen Blom, Carol G. Chitko-Mckown, Michael L. Clawson

School of Veterinary and Biomedical Sciences: Faculty Publications

Moraxella bovoculi is a recently described bacterium that is associated with infectious bovine keratoconjunctivitis (IBK) or “pinkeye” in cattle. In this study, closed circularized genomes were generated for seven M. bovoculi isolates: three that originated from the eyes of clinical IBK bovine cases and four from the deep nasopharynx of asymptomatic cattle. Isolates that originated from the eyes of IBK cases profoundly differed from those that originated from the nasopharynx of asymptomatic cattle in genome structure, gene content and polymorphism diversity and consequently placed into two distinct phylogenetic groups. These results suggest that there are genetically distinct strains of M. …

Assembly And Regulation Of The Dream Complex, Jessica G. Felthousen

Theses and Dissertations

The DREAM complex assembles during G0/G1 when RB-like protein p130 recruits E2F4, DP1, and a core complex of five MuvB proteins to repress genes involved in cell cycle progression. In S-phase, the MuvB core dissociates from p130 and binds to BMYB transcription factor. Binding of the MuvB core to p130 requires phosphorylation of its subunit LIN52 at S28 residue by DYRK1A protein kinase. However, little is known about how the MuvB core interacts with p130 to form the DREAM complex, and how these interactions are manipulated throughout the cell cycle. In collaboration with Dr. Seth Rubin, we characterized the structural …
