Impaired Skeletal Muscle Blood Flow Control With Advancing Age In Humans: Attenuated Atp Release And Local Vasodilation During Erythrocyte Deoxygenation, Brett S. Kirby, Anne R. Crecelius, Wyatt F. Voyles, Frank A. Dinenno

Health and Sport Science Faculty Publications

Rationale: Skeletal muscle blood flow is coupled with the oxygenation state of hemoglobin in young adults, whereby the erythrocyte functions as an oxygen sensor and releases ATP during deoxygenation to evoke vasodilation. Whether this function is impaired in humans of advanced age is unknown.

Objective: To test the hypothesis that older adults demonstrate impaired muscle blood flow and lower intravascular ATP during conditions of erythrocyte deoxygenation.

Methods and Results: We showed impaired forearm blood flow responses during 2 conditions of erythrocyte deoxygenation (systemic hypoxia and graded handgrip exercise) with age, which was caused by reduced local vasodilation. In young adults, …

Mapping The Extent Of Plural Marriage In St. George, 1861–1880, Lowell C. Bennion

BYU Studies

This article is one of a set on the practice of polygamy in St. George, Utah, from 1861 to 1880. It asks why polygamy rates in that Mormon settlement exceed the demographic limits produced by Bitton and Lambson in their article "Demographic Limits of Nineteenth-Century Mormon Polygyny." Bitton and Lambson suggest that "those willing to accept an assignment to settle in St. George were very committed Mormons, and those who remained in St. George after having observed conditions firsthand were more committed still. Very committed Mormons were much more likely to practice polygamy than were others."

Using case studies of …

Changes In Expression Profiles Of Energy Metabolism And Cellular Calcium Balance Genes In The Mammalian Inner Ear During Development, Audrey Freedman

Intersections Fall 2020

The incurable and devastating disease of age-related hearing loss (ARHL) affects a majority of the elderly worldwide. As humans age, their cells of the inner ear, which are responsible for hearing, undergo degenerative aging, as well as apoptosis (programmed cell death). Scientists believe that ARHL may be associated with specific cell types of the inner ear known to be high in mitochondrial concentration. These sensorineural tissues as well as the specific neurons, namely hair cells, spiral ganglion neurons, and cells of stria vascularis, are susceptible to irreversible cellular damage. A decline of mitochondrial function is common in various age-dependent neurodegenerative …

Optimizing Aplysia Californica's Living Conditions, Ruiying Xu

Intersections Fall 2020

The marine mollusk Aplysia californica is an important model organism for neuroscience research. In laboratory aquaria, animal waste may accumulate and harm animals unless water is replaced frequently. To keep animals healthy for longer, we have designed a marine environment that replicates the natural nitrogen cycle. Our animals' holding tanks have two compartments: a main compartment for animals and a refugium for macroalgae. We are studying whether ammonia and nitrate derived from animal waste cause illness in Aplysia, and whether macroalgae can sequester nitrates and reverse illness. We measured increases in nitrate and ammonia in the absence of macroalgae. We …

Avataraudiometer: An Online Simulation Platform For Pure-Tone Audiometry, Daniel Weidman, Lauren Calandruccio

Intersections Fall 2020

Simulation education for medical and health professional training bridges classroom learning and training in a clinical environment. Its use has been increasing over the past two decades. Guidance to avoid in-person contact due to SARS-CoV-2 has further increased demand. Pure-tone audiometry is part of an audiometric test battery used to evaluate the auditory system. At Case Western Reserve University, students typically learn to conduct audiometry in COSI 370: Introduction to Audiology. Under current pandemic circumstances, students are unable to gain in-person experience using standard hardware (an audiometer and calibrated headphones). AvatarAudiometer solves this problem via an interactive online tool that …

Asynchronous Ultrasonic Trilateration For Indoor Positioning Of Mobile Phones, Viacheslav Filonenko (Thesis)

Theses

Spatial awareness is fast becoming the key feature on today‟s mobile devices. While accurate outdoor navigation has been widely available for some time through Global Positioning Systems (GPS), accurate indoor positioning is still largely an unsolved problem. One major reason for this is that GPS and other Global Navigation Satellite Systems (GNSS) systems offer accuracy of a scale far different to that required for effective indoor navigation. Indoor positioning is also hindered by poor GPS signal quality, a major issue when developing dedicated indoor locationing systems. In addition, many indoor systems use specialized hardware to calculate accurate device position, as …

Behavioral Observations Surrounding A Diet Change Of Zoo-Housed Matschie's Tree Kangaroos (Dendrolagus Matschiei), Sarah Miller, Noah T. Dunham, Diana Koester

Intersections Fall 2020

The diet of zoo-housed animals has significant implications to many aspects of each species' health and survival. A recent study revealed the diet of free-ranging Matschie's tree kangaroos (Dendrolagus matschiei) to be mostly browse-focused, including plants like leaves, ferns, and orchids. Prior to those findings, zoo-housed tree kangaroos were fed diets, mostly biscuit-based, that differ vastly from that of free-ranging tree kangaroos possibly contributing to widespread issues within zoos concerning obesity and low reproductive success. The Cleveland Metroparks Zoo (CMZ) houses two Matschie tree kangaroos which, in 2019, underwent a significant diet change from a more traditional, baseline, biscuit-heavy diet …

Recovery Among Homeless Populations With Severe Mental Illness And Substance Use Disorders, Abigail M. Cross

Intersections Fall 2020

Homelessness among persons with severe mental illness (SMI) and co-occurring substance use disorders (SUD) is a prominent social issue in the United States today. Not only do persons with SMI make up a significant portion of the overall homeless population, SUDs make it more difficult for them to recover successfully. Recovery among these populations is multi-faceted, and all aspects of recovery should be accounted for so that this population has the best chance to succeed. There are a number of programs in place that attempt to place persons with SMI and SUD into housing while providing treatment, including Permanent Supportive …

Wheelchair Athlete Concussion Baseline Data: A Pilot Retrospective Analysis, Jonathan Lee, Michael Harper, Michael Uihlein, Kenneth Lee

Intersections Fall 2020

After a thorough literature search and through experience at adaptive sports events, we identified a lack of established guidelines for Sport-related concussion (SRC) evaluation and management in wheelchair athletes. Wheelchair athletes are a unique population, and certain conventional methods of evaluating SRC in able-bodied sports cannot be used. For example, wheelchair athletes' underlying disabilities restrict the use of standard balance testing protocols. In addition, some wheelchair athletes have concurrent traumatic brain injuries and may have baseline cognitive deficits associated with their disability that mimic the symptoms of a concussion. This research focused on discussing current concussion management guidelines in Adaptive …

Engineering Titanium Dioxide Nanoparticles For Bacterial Biofilm Treatment, Massado Ngompe, Yu Hsin Tsai, Nathalie Milbrandt, Zhuoying Jiang, Xiong Yu, Anna Cristina S. Samia

Intersections Fall 2020

Titanium dioxide nanoparticles (TiO2 NPs) are non-toxic and biocompatible materials that are used for a wide range of applications such as pigments, sunscreens, cosmetics, and food colorings. TiO2 possesses a large band gap (3.2 eV) which, by heteroatom doping or by molten salt/hydrogen assisted reduction, can be narrowed to allow for activity within the visible light spectrum making them optimal candidates for use in bacterial biofilm eradication. Nitrogen-doped and reduced TiO2 NPs have been explored in this study due to their narrowed band gap. The narrowed band gap allows for the formation of excitons upon the absorption of light within …

Water Bankruptcy, Christine A. Klein

UF Law Faculty Publications

Many western states are on the verge of bankruptcy, with debts exceeding assets. And yet, they continue to take on additional debt through contracts and other commitments. Although this distress sounds like an outgrowth of the 2008 recession, this crisis involves water, not money. In particular, the problem concerns the western prior appropriation system of water law, which allocates the right to use water under the priority principle of “first in time, first in right.” In many states, the system is so “over-allocated” that it promises to deliver annually much more water than nature provides. The crisis will deepen as …

A Motivated Workforce: A Mixed Methods Study Of Worker Motivation At A Nebraska Manufacturing Company, Kevin Wesley

Department of Educational Administration: Dissertations, Theses, and Student Research

The study of worker motivation and human motivation in general, has been the focus of psychologists, sociologists, behavioral scientists, and leadership theorists for more than a century. An understanding of the factors that motivate workers is critical not only to corporate executives who concentrate on the bottom line, but more importantly to the security of our nation as it relates to competing in the global market. The purpose of this mixed-methods study is to examine worker motivation in a Nebraska manufacturing company. A pragmatist worldview informs the convergent parallel design of this study, which consists of a qualitative strand using …

Preservice Teachers' Perceptions Of Their Knowledge And Application Of Response To Intervention, Carrie Dannelle Jepma

Theses and Dissertations

Response to Intervention (RTI) is a model for providing instructional and scientific-based interventions to all children who struggle. RTI uses data-based decision making for the interventions, instructional evaluation, intervention intensity and length of time, and evaluation and recommendations for any adjustments needed in instruction in both the problem-solving and standard protocol models. The difference between the two models of RTI is that the interventions are individualized for each student in the problem-solving model, but not the standard protocol model.

RTI has been used by schools and agencies with research to support that it meets the needs of children and is …

Effets Du Sida Sur La Côte D'Ivoire Et Stratégies Culturellement Pertinentes Pour En Prévenir La Propagation, Austin Lawry

The Kennesaw Tower Undergraduate Foreign Language Research Journal

Côte D’Ivoire remains a vital case in the fight against AIDS proliferation due to its status as one of the most centralized and influential state in West Africa. This paper analyzes the unique case that Côte D’Ivoire presents socially, economically and politically and how an effective and comprehensive prevention program must incorporate these three dimensions. Particular attention is given to the impact of recent cultural shifts in understanding HIV/AIDS, the Migrant Labor Thesis, the costs of the disease, and the role of war. Finally, through integrating these unique dimensions with the problems reported by existing AIDS prevention programs, several solutions …

On The Importance Of Modeling Stent Procedure For Predicting Arterial Mechanics, Shijia Zhao, Linxia Gu, Stacey R. Froemming

Department of Mechanical and Materials Engineering: Faculty Publications

The stent-artery interactions have been increasingly studied using the finite element method for better understanding of the biomechanical environment changes on the artery and its implications. However, the deployment of balloon-expandable stents was generally simplified without considering the balloon-stent interactions, the initial crimping process of the stent, its overexpansion routinely used in the clinical practice, or its recoil process. In this work, the stenting procedure was mimicked by incorporating all the above-mentioned simplifications. The impact of various simplifications on the stent-induced arterial stresses was systematically investigated. The plastic strain history of stent and its resulted geometrical variations, as well as …
