Excess Folic Acid As A Potential Competitor Of Glutamate May Interfere With Neural Development, Benjamin Fick

Honors Program Theses

Folic acid, Vitamin B9, is strongly advised as a supplement taken by pregnant woman to maintain the health of the embryo, and deficiency increases the risk of neural tube defects. However, a safe upper limit of folate to consume has not been established, and an excess of dietary folate may interfere with neurodevelopmental metabolism, increasing the risk of adverse outcomes, including autism spectrum disorder (ASD). It has been suggested that folate affects connectivity among neurons as the brain develops. Glutamate is important in the regulation of neural tissue development, as it is a common excitatory neurotransmitter that binds to synaptic …

Branding The Uni/Wellness Recreation Center: Creating A Cohesive Cross-Media Collegiate Recreation Identity, Rachael Bair

Honors Program Theses

This thesis produced a branded cross‐media campaign for the UNI Recreation Services department. A brand, or visual identity, was needed to tie together all of the promotional materials being produced for Recreation Services. Before I created the brand, the department's materials did not have a consistent visual style, and each program within the department maintained its own materials. As a result, visitors who came to the department office often left with a handful of visually inconsistent printed materials. Additionally, print materials often needed to incorporate large areas of purple and gold in order to stay within guidelines set by University …

Atmospheric Cold Plasma Interactions With Modified Atmosphere Packaging Inducer Gases For Safe Food Preservation., Lu Han, Daniela Boehm, Vladimir Milosavljević, Ester Amias, Patrick J. Cullen, Paula Bourke

Articles

Diverse microbiological challenges and pervasive microbial resistance drive technological development in food processing, where increasing process complexity and consumer demand for less processed goods leads to strong demand for effective decontamination. Atmospheric cold plasma (ACP) has wide potential for decontamination application in the food sector. We investigated the effect of Modified Atmosphere Packaging (MAP) gas mixtures on reactive species generated, their efficacy and mechanism of inactivation against Escherichia coli, Listeria monocytogenes and Staphylococcus aureus. Oxygen levels in the applied working gas had positive interactive effects on ROS generation, in-package inactivation efficacy in conjunction with post-treatment storage time. …

Federal Constitutional Childcare Parents, Jeffrey A. Parness

Faculty Articles, Papers, and Other Scholarship

The U.S. Supreme Court has long recognized federal constitutional childcare rights in parents that may not be easily diminished or eliminated by government. Yet it has allowed these childcare rightsholders to be chiefly defined by state laws. The relevant state laws vary widely, dependent upon such factors as biological ties, functional parenthood, contracts, and the avenues to conception. Deference to state lawmaking here is unique. No other federal constitutional rightsholders are so significantly defined by state statutes and precedents. This deference has resulted in significant interstate variations in de facto parent, equitable adoption, presumed parent and surrogacy matters, as well …

Behavior And Survival Of The Filth Fly Parasitoids Spalangia Endius And Urolepis Rufipes (Hymenoptera: Pteromalidae) In Response To Three Granular House Fly Baits And Components., Edwin R. Burgess, Bethia H. King

Faculty Articles, Papers, and Other Scholarship

Behaviors and mortality of two filth fly parasitoid wasps, Spalangia endius Walker and Urolepis rufipes Ashmead, were tested in response to granular fly baits containing one of three active ingredients (AI): Golden Malrin (methomyl), QuickBayt (imidacloprid), or Quikstrike (dinotefuran). Behavioral responses to each of two components of the baits, the AIs and the fly attractant pheromone (Z)-9-tricosene, were also examined independently. S. endius avoided contact with bait granules, regardless of bait type. However, when S. endius contacted bait residue, the imidacloprid bait appeared to be the least harmful of the baits for S. endius, at least in the short term. …

Effects Of Size And Age Of The Host Musca Domestica (Diptera: Muscidae) On Production Of The Parasitoid Wasp Spalangia Endius (Hymenoptera: Pteromalidae), S.A. Broski, Bethia H. King

Faculty Articles, Papers, and Other Scholarship

One method of control of house flies, Musca domestica L. (Diptera: Muscidae), and other filth flies is by repeated release of large numbers of pupal parasitoids such as Spalangia endius Walker. Rearing these parasitoids may be facilitated by understanding how host factors affect their production. Previous studies have examined the effects of host size and host age on parasitoid production, but have not examined the interaction between host size and host age or the effects with older females, which may be less capable of drilling tough hosts. Females were given hosts of a single size-age category (small young, small old, …

Bacterial Regulon Modeling And Prediction Based On Systematic Cis Regulatory Motif Analyses, Bingqiang Liu, Chuan Zhou, Guojun Li, Hanyuan Zhang, Erliang Zeng, Qi Liu, Qin Ma

School of Computing: Faculty Publications

Regulons are the basic units of the response system in a bacterial cell, and each consists of a set of transcriptionally co-regulated operons. Regulon elucidation is the basis for studying the bacterial global transcriptional regulation network. In this study, we designed a novel co-regulation score between a pair of operons based on accurate operon identification and cis regulatory motif analyses, which can capture their co-regulation relationship much better than other scores. Taking full advantage of this discovery, we developed a new computational framework and built a novel graph model for regulon prediction. This model integrates the motif comparison and clustering …

"Just Because I'M An Only Child Doesn't Mean I Can't Have Siblings:" Psychological Kinship Within Social Support Networks, Alynn C. Hembrough

Scripps Senior Theses

Pulling from the foundations of research on social support and resilience indicating that those who receive extensive social support are more resilient, this research, consisting of two studies, primarily examined the differences between individuals who are only children and individuals who have siblings in their formation of social support networks. While it is true that only children inherently have less immediate kin available, this research explored the formation of relationships in which non-kin come to be psychologically considered as kin, or psychological kinship. In Study 1, qualitative interviews were conducted in order to develop a working Kinship scale. Study 2, …

Cooking With Roots: How Older Adults Strengthen Connection With Younger Generations Through Recipe Sharing, Laurel R. Kitada

Scripps Senior Theses

This research investigates how older adults experience sharing recipes with younger generations, and examines conditions that contribute to the expression of generativity within the context of intergenerational recipe sharing. In Study 1, semi-structured interviews centered on experiences with intergenerational recipe sharing will be conducted with 30 older adults (age 65+). Participants will complete a survey of generative concern before and after engaging in a basic recipe sharing task. In line with previous research on generative art activities, responses will highlight feelings of autonomy as well as desires to teach others and leave a legacy. It is also hypothesized that generative …

You Can't Catch A Fish With A Robot, R. Grant Gilmore Jr.

Gulf and Caribbean Research

Abstract

In this essay I will relate the challenges associated with deep sea ocean exploration as well as the advantages and disadvantages of today’s ocean technologies based on experience with most of these systems. After nearly five decades using robotic vehicles (Remotely Operated Vehicles = ROVs and Autonomous Underwater Vehicles = AUVs) and manned submarines for fish research, I thought it would be appropriate to briefly describe a career spent using these technologies as they were developed. Deep sea ichthyologists cannot effectively catch a swimming fish with a robot even 40 years after the development of the first ROV for …

Age, Growth And Natural Mortality Of Blackfin Snapper Lutjanus Buccanella From The Southeastern United States And U. S. Caribbean, Michael L. Burton, Jennifer C. Potts, Daniel R. Carr

Gulf and Caribbean Research

We determined ages of Blackfin Snapper (Lutjanus buccanella Cuvier 1828; n = 622) collected from the southeastern United States coast and U.S. Caribbean from 1979–2015 using sectioned sagittal otoliths. Opaque zones were determined to be annular, forming March – July (peaking in April–June). Blackfin Snapper ranged from 1–27 years and from 180–609 mm total length (TL). Body size relationships for Blackfin Snapper were: TL = 1.09 FL + 0.81 (n = 203, r2 = 0.99); FL = 0.91 TL + 3.38 (n = 203, r2 = 0.99); TL = 1.23 SL + 14.27 (n = 83, r2 = 0.97); FL …

Why Coywolf Goes To Court, Signa A. Daum Shanks

Articles & Book Chapters

This article is an effort influenced by previous works considered part of "trickster" discourse. But unlike other trickster stories meant to illustrate First Nations’ contents and processes, this presentation creates a Métis-specific example of trickster methodology and knowledge. Similar to the historic role Métis individuals have had in Canadian history, this effort contains a type of "translator" system within its citations so that the main story parallels information about trends in Canadian legal analysis. By having this format, it is hoped that those less familiar with Métis courtroom struggles will gain insight into how the pursuit of Métis constitutionalism both …

Emerging Roles Of Adamts Metalloproteinases In Regenerativemedicine And Restorative Biology, Ferah Armutcu, Kadi̇r Demi̇rcan

Turkish Journal of Biology

ADAMTS (a disintegrin and metalloprotease with thrombospondin motifs) proteinases degrade proteoglycans and thereby have the potential to alter tissue architecture and regulate cellular function. Recent studies about the roles of these enzymes have produced new perspectives for the molecular mechanisms behind regenerative biology with clinical potential to generate therapeutic targets to resolve tissue injury. ADAMTS enzymes play an important role in the turnover of extracellular matrix proteins in various tissues and their dysregulation has been implicated in disease-related processes such as inflammation and fibrosis. Increasing evidence indicates that they may be of key significance in the physiological and pathological central …

Controlled Nitric Oxide Release For Tissue Repair And Regeneration, Yan Nie, Zongjin Li

Turkish Journal of Biology

The discovery that nitric oxide (NO) plays crucial roles in mammalian systems has spurred considerable interest in its translational application. However, the major problem with its application in clinical settings is the high reactivity of NO, which makes it difficult to supply NO with spatiotemporal accuracy while maintaining its bioactivity. To deliver NO at a specified rate to a preferred location for a precise period of time is highly demanded. The significant technological advancements in controlled release make it possible to control NO release at the target site with a sustained release rate and an optimum concentration, and then provide …

Investigation Of The Natural Bacteriocin Nisin And Bioengineered Nisin Derivatives For The Prevention And Control Fo Staphylococcus Biofilms On Medical Device Materials, Leanne Kearney

Theses

Antimicrobial resistance has evolved into being one the major threats facing clinical environments worldwide. It has led to the deerease in effective prevention and treatment of pathogenic bacteria. One such bacterium is Staphylococcus epidermidis. Once considered a relatively harmless and commensal baeterium, it has recently evolved into being one the leading eauses of nosocomial infections. S. epidermidis has proven hamiful due to its ability to fonn detrimental biofilms. Biofilms are structured eonsortia of bacteria embedded in a self-produced polymer matrix that allows adherence to biotic or abiotic surfaces. These biofilms have played a leading role in healthcare-acquired infections with particular …

Marine Infectious Disease Dynamics And Outbreak Thresholds: Contact Transmission, Pandemic Infection, And The Potential Role Of Filter Feeders, Gorka Bidegain, Eric N. Powell, John M. Klinck, Tal Ben-Horin, Eileen E. Hofmann

CCPO Publications

Disease-causing organisms can have significant impacts on marine species and communities. However, the dynamics that underlie the emergence of disease outbreaks in marine ecosystems still lack the equivalent level of description, conceptual understanding, and modeling context routinely present in the terrestrial systems. Here, we propose a theoretical basis for modeling the transmission of marine infectious diseases (MIDs) developed from simple models of the spread of infectious disease. The models represent the dynamics of a variety of host-pathogen systems including those unique to marine systems where transmission of disease is by contact with waterborne pathogens both directly and through filter-feeding processes. …

Spatiotemporal Analysis Of Gene Flow Patterns Among Woodland Salamander Populations Inhabitating Contrasting Landscapes, Alexander C. Cameron

Masters Theses

Dispersal is a fundamental evolutionary process that serves as a mechanism by which local populations remain connected through space. Habitat loss and fragmentation remain widespread threats to biodiversity globally, and therefore it is imperative to understand how dispersal patterns are affected by anthropogenic modifications of the environment. Using a panel of 10 novel microsatellite loci, I estimated gene flow patterns over historical and contemporary timescales among populations of Eastern Red-backed Salamanders (Plethodon cinereus) in a previously unstudied portion of the species range. Four focal populations reside within a highly fragmented urban center whereas the remaining four focal populations persist in …

Vitamin D Levels In Black African Adults At The Aga Khan University Hospital Nairobi, Elizabeth Muringa Kagotho

Master of Medicine in Clinical Pathology

Introduction: Vitamin D has been known for centuries for its benefits in bone health. Recent observational studies have however demonstrated its benefits in infectious diseases such as tuberculosis and non-communicable diseases such as diabetes mellitus, cardiovascular diseases and cancer. This has led to a dramatic increase in testing among adults. The cut-offs for vitamin D deficiency have been debated for decades and the current cut off is derived from a Caucasian population. Studies done among black African adults in Africa are few and have shown that vitamin D deficiency ranges from 5-91%. In view of the difference in skin colour, …

An Interactive Tool For The Computational Exploration Of Integrodifference Population Models, Kennedy Agwamba

HMC Senior Theses

Mathematical modeling of population dynamics can provide novel insight to the growth and dispersal patterns for a variety of species populations, and has become vital to the preservation of biodiversity on a global-scale. These growth and dispersal stages can be modeled using integrodifference equations that are discrete in time and continuous in space. Previous studies have identified metrics that can determine whether a given species will persist or go extinct under certain model parameters. However, a need for computational tools to compute these metrics has limited the scope and analysis within many of these studies. We aim to create computational …

Hopper Bands: Locust Aggregation, Ryan C. Jones

HMC Senior Theses

Locust swarms cause famine and hunger in parts of Sub-Saharan Africa as they travel across croplands and eat vegetation. Current models start with biological properties of locusts and analyze the macroscopic behavior of the system. These models exhibit the desired migratory behavior, but do so with too many parameters. To account for this, a new model, the Alignment and Intermittent Motion (AIM) model, is derived with minimal assumptions. AIM is constructed with regards to locust biology, allowing it to elicit biologically correct locust behavior: the most noteworthy being the fingering of hopper bands. A Particle-in-Cell method is used to optimize …

Prediction Of Metal Remobilization From Sediments Under Various Physical/ Chemical Conditions “Design Of Experiments Cd, Co And Pb”, Eid A. Alkhatib, Trey Chabot, Danielle Grunzke

Chemistry & Physics Faculty Publications

The metal partition coefficient Kd (L/kg) is the ratio of sorbed metal concentration on the solid phase m (mg/kg) to the dissolved metal concentration at equilibrium. The behavior of metals in surface water is complex and their partition coefficients can be impacted by many factors. Organic matter (OM) content in sediments, pH and salinity, are factors that may influence speciation and partitioning of metals. In this study, the partitioning coefficient of three metals (Cd, Co and Pb) under different levels of salinity, pH, and OM content were examined. A series of factorial experiments were evaluated in which three levels of …

Complexity Under Stress: Integrative Approaches To Overdetermined Vulnerabilities, Patricia Andrews Fearon, Eolene M. Boyd-Macmillan

Journal of Strategic Security

Over four decades of cognitive complexity research demonstrate that higher integrative complexity (measured by the ability to differentiate and integrate multiple dimensions or perspectives on an issue) predicts more lasting, peaceful solutions to conflict. Interventions that seek to raise integrative complexity offer a promising approach to preventing various forms of intergroup conflict (e.g. sectarianism, violent extremism). However, these contexts can also be extremely stressful, and dominant theory suggests that cognitive complexity diminishes in the face of high stress. However, we know that this is not always the case, with some findings demonstrating the opposite pattern: increases in complexity under high …
