Proteomic Analysis Of Fetal Rat Neural Stem Cells After Treatment With Hericium Erinaceus, Bright Adam Test

University of the Pacific Theses and Dissertations

The fungus, Hericium erinaceus, has outstanding chemical properties, displaying health benefits in digestive, hepatic, and nervous tissues. Its ease of accessibility and use makes it one of the most common substances used for treatment in Eastern medicine. More and more recent research is confirming the incredible health benefits of this fungus, especially the impact that is seen on nervous tissue growth and recovery post-treatment. Such neurite outgrowth and myelin sheath regeneration could illustrate the beginning of the cure to lifelong neurodegenerative diseases such as Multiple Sclerosis. In this first-of-its-kind study, we cultured and differentiated fetal rat neural stem cells while …

Amphibian Vocalization: Implications Of A Novel Laryngeal Muscle In The Calling Mechanisms Of The TúNgara Frog Engystomops Pustulosus, Amy D. Lagorio

University of the Pacific Theses and Dissertations

The current functional model of the anuran larynx includes four pairs of laryngeal muscles. Their contractions do not account, however, for the behavioral control of call complexity observed in male túngara frogs (Engystomops pustulosus), which optionally add a secondary note with distinct harmonic structure to their advertisement call. Examination of the túngara frog's laryngeal morphology through dissection, microtomography, and resin histology has revealed that the m. dilatator laryngis is divided into two separate bundles (superficial and deep). The superficial bundle closely matches the typical description of the m. dilatator laryngis and is well positioned to open the glottis. …

Prevalence Of Dirofilaria Immitis In Southern California’S Invasive Aedes Species And Native Culiseta Incidens, Zaina Chaban

University of the Pacific Theses and Dissertations

Dirofilaria immitis is a mosquito-borne parasite that causes dog heartworm disease, effecting over 100,000 dogs in the United States each year (CAPC - Parasite Prevalence Maps., 2021). Increased disease reports are commonly attributed to an increase in the local mosquito vector population. Since 2013, dog heartworm disease cases have increased by approximately 21% in the United States as reported by the American Heartworm Society. During the same time, invasive mosquitoes belonging to the genus Aedes have been found in Southern California and spread to other areas. The purpose of our research was to determine the prevalence of Dirofilaria …

Biology Of Binge Eating Related Disorders And Proposal For Integration Into Treatment, Karlyne Morawe

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

The concerningly low recovery and high cross over rates of eating disorders with binge eating behaviors suggests there might be a missing element in current treatment approaches commonly used to address eating disorders. Research supports the existence of significant biological correlation between disorders that are characterized by binge eating behaviors. This paper examines some of the biological processes in which these disorders show the most significant correlations. These include the organism’s response to caloric restriction, the brain’s response to feeding, the biological drive for reproduction, sensory association to feeding, and habituated responding to the feeding process. Additionally, we will explore …

A Mixed-Methods Study Of Entomology Incorporation In U.S. Secondary Science Instruction, Erin M. Ingram

Department of Entomology: Dissertations, Theses, and Student Research

To encourage understanding and appreciation of insects, entomology education advocates have supported and encouraged K-12 teachers to integrate insects and insect-related content into formal science instruction. However, research examining how and why science teachers incorporate entomology into secondary science courses is limited.

A sequential explanatory mixed-methods research study was conducted to address this gap. The study was conducted in two phases. During the first phase, quantitative survey research was conducted with a representative sample of 254 U.S. secondary life science teachers. During the subsequent qualitative phase, follow-up interviews were conducted with a purposeful sample of 18 survey participants and an …

Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding

Animal Science Undergraduate Honors Theses

Belize is a small country, but it is extremely ecologically diverse. Based on the few studies conducted in Belize, the abundance of mammals is low but diversity is high. Particular findings note the number and identity of species differed between four sites in the Maya Mountains of Belize, indicating that a data set from a single site is not representative of the Neotropical region. Insufficient data is available to estimate current species richness of many areas in Belize, including Billy Barquedier National Park (BBNP). The objective of this study was to explore trapping and documentation methods of terrestrial mammals in …

Science and Technology Department Faculty Journal Articles

Heterotrophic protists play pivotal roles in aquatic ecosystems by transferring matter and energy, including lipids, from primary producers to higher trophic predators. Using Oxyrrhis marina as a model organism, changes to the non-saponifiable protist lipids were investigated under satiation and starvation conditions. During active feeding on the alga Cryptomonas sp., the O. marina hexane soluble non-saponifiable fraction lipid profile reflected its food source with the observed presence of long chain mono-unsaturated fatty alcohols up to C25:1. Evidence of trophic upgrading in O. marina was observed with long chain mono-unsaturated fatty alcohol accumulation of up to C35:1. To the best of …

Traffic Noise And Sexual Selection: Studies Of Anthropogenic Impact On Bird Songs And Undergraduate Student Reasoning Of Evolutionary Mechanisms, Sarah Spier

School of Natural Resources: Dissertations, Theses, and Student Research

Humans have transformed much of the natural landscape and are continuing to do so at an accelerated rate, compromising natural areas that serve as important habitat for many species. Roads impact much of the environment as they fragment habitat and introduce traffic noise into the acoustic environment, deferentially affecting wildlife in roadside habitat. I explored how traffic noise affects the detection of birds based on whether their vocalizations were masked by traffic noise. Masked species detection was not affected by an increase in traffic noise amplitude, while there was a negative effect of traffic noise amplitude on unmasked species detection, …

The Evolutionary Diversity And Biological Function Of Phenazine Metabolite Biosynthesis In Burkholderia Spp, Samuel Hendry

Master's Theses

Burkholderia encompass a group of ubiquitous Gram-negative bacteria that include numerous saprophytes, as well as several species that cause infections in animals, immunocompromised patients, and plants. Some species of Burkholderia produce colored redox-active secondary metabolites called phenazines (Phz). In the model opportunistic pathogen Pseudomonas aeruginosa, phenazines strongly contribute to the competitiveness, formation of biofilms, and virulence in multiple models of infection. Similar depth of knowledge on the diversity, biosynthesis, and biological functions of phenazines in Burkholderiais missing. This project aimed to bridge this gap in knowledge by focusing on phenazine pathways of B. lata and closely related …

Long-Billed Curlew Nest Site Selection And Success In The Intermountain West, Stephanie E. Coates, Benjamin W. Wright, Jay D. Carlisle

Intermountain Bird Observatory Publications and Presentations

Grassland birds have experienced steeper population declines between 1966 and 2015 than any other bird group on the North American continent, and migratory grassland birds may face threats in all stages of their annual cycle. The grassland‐associated long‐billed curlew (Numenius americanus) is experiencing population declines in regional and local portions of their North American breeding range. The nesting period is an important portion of the annual cycle when curlews may face demographic rate limitations from a suite of threats including predators and anthropogenic disturbance. We compared nest sites to random sites within breeding territories to examine nest site …

Electrostatically Localized Proton Bioenergetics: Better Understanding Membrane Potential, James Weifu Lee

Chemistry & Biochemistry Faculty Publications

In Mitchell's chemiosmotic theory, membrane potential Δψ was given as the electric potential difference across the membrane. However, its physical origin for membrane potential Δψ was not well explained. Using the Lee proton electrostatic localization model with a newly formulated equation for protonic motive force (pmf) that takes electrostatically localized protons into account, membrane potential has now been better understood as the voltage difference contributed by the localized surface charge density ([H-⁺_L] + ⁿΣ _i=1 [M⁽ⁱ⁺⁾_L]) at the liquid-membrane interface as in an electrostatically localized protons/cations-membrane-anions capacitor. That is, the origin of membrane …

A Rapid Viability And Drug‑Susceptibility Assay Utilizing Mycobacteriophage As An Indicator Of Drug Susceptibilities Of Anti‑Tb Drugs Against Mycobacterium Smegmatis Mc2 155, Gillian Catherine Crowley, Jim O'Mahony, Aidan Coffey, Riona G. Sayers, Paul D. Cotter

Department of Biological Sciences Publications

Background: A rapid in-house TM4 mycobacteriophage-based assay, to identify multidrug resistance against various anti-tuberculosis drugs, using the fast-growing Mycobacterium smegmatis mc² 155 in a microtiter plate format was evaluated, based on phage viability assays. Methods: A variety of parameters were optimized before the study including the minimum incubation time for the drugs, phage and M. smegmatis mc² 155 to be in contact. An increase in phage numbers over 2 h was indicative that M. smegmatis mc² 155 is resistant to the drugs under investigation, however when phage numbers remained static, M. smegmatis mc² 155 found to …

Do Stands Of Native Trees Harbor Different Invasive Species Than Stands Of Planted Pine?, Carly Mccameron, John Mccarthy, Dr. Kevin Geedey

Celebration of Learning

The most outstanding invasive species that can be found at Augustana’s Green Wing Environmental Laboratory are honeysuckle, buckthorn, multiflora rose, garlic mustard, autumn olive, and oriental bittersweet. These plants are not only disrupting the ecosystem at Green Wing, but they are doing it all over the country. The result of their disruption is that they have taken over entire habitats and left natural species with no way to compete for survival. To study this we used the line-point method as well as other forms of data collection to compare a non-native pine tree habitat to an area dominated by native …
