Chytridiomycota In Tree Bark, Paige Strasko
Chytridiomycota In Tree Bark, Paige Strasko
Honors College
Chytridiomycota is a phylum of microscopic aquatic fungi that form motile spores that typically have a single posterior flagellum, thus they require water to disperse (James et al., 2000). Chytridiomycota, collectively called chytrids, have round shapes with structures called rhizoids that absorb nutrients and anchor them to their substrate (Mueller et al., 2004). Chytrids are typically found in aquatic environments and soils since zoospores require water to germinate (James et al., 2000), but they also have been found in a number of unexpected environments. Chytrids are difficult to find because they are microscopic and have time-sensitive life cycles (Mueller et …

Beyond The Brain: A Study Of Α-Synuclein's Role In Bone And Adipose Tissue, Carolina A. Figueroa
Beyond The Brain: A Study Of Α-Synuclein's Role In Bone And Adipose Tissue, Carolina A. Figueroa
Electronic Theses and Dissertations
α-Synuclein is a polypeptide encoded by the Snca gene, highly expressed in neurons, but it is also found in bones and adipose tissue. Co-expression analysis showed that Snca regulates skeletal homeostasis, and its deletion reduced estrogen deficiency-induced bone loss and weight gain. It is a major component of Lewy bodies (LB) in Parkinson’s disease (PD), leading to progressive immobilization and a range of nonmotor symptoms, including osteopenia, body composition alterations and insulin resistance. This thesis aimed to determine α-Synuclein’s intrinsic role in bone and adipose homeostasis. We discussed the PD pathophysiology emphasizing aspects of bone health and metabolism. By using …
Zebrafish As A Model To Understand The Impact Of Inactivity And Neuromuscular Electrical Stimulation On Duchenne Muscular Dystrophy, Elisabeth Kilroy
Zebrafish As A Model To Understand The Impact Of Inactivity And Neuromuscular Electrical Stimulation On Duchenne Muscular Dystrophy, Elisabeth Kilroy
Electronic Theses and Dissertations
Skeletal muscle plasticity is imperative for functional adaptation to changing demands in activity. Although a great deal is known about the structural and functional plasticity of healthy skeletal muscle, far less is known about plasticity in diseased muscle. Here, we combined the power of the zebrafish model with the adaptability of neuromuscular electrical stimulation (NMES) to study the basic mechanisms of plasticity in the zebrafish model of Duchenne Muscular Dystrophy (DMD). Four NMES paradigms, defined by their frequency, delay, and voltage, were designed to emulate the repetition and load schemes of human resistance training programs. Additionally, two inactivity paradigms were …

Does Circularizing Source-Separated Food Waste Present A Risk To Our Food?, Astha Thakali
Does Circularizing Source-Separated Food Waste Present A Risk To Our Food?, Astha Thakali
Electronic Theses and Dissertations
About a third of the food produced annually is wasted. Food waste recycling can be a way to close the loop and attain a more sustainable food system, however, the system must be carefully monitored and managed to avoid the introduction and build-up of contaminants. To study the potential presence of contaminants in food waste, source-separated food waste was collected and screened for five classes of contaminants (physical contaminants, heavy metals, halogenated organic contaminants, pathogens, and antibiotic resistance genes) from two separate regulatory environments (voluntary vs mandated food separation). The regulatory environment did not affect the level of contamination, except …
Cpap-Compliance Of Aging Individuals With Obstructive Sleep Apnea With Or Without Mild Cognitive Impairment, Bailey Carter
Cpap-Compliance Of Aging Individuals With Obstructive Sleep Apnea With Or Without Mild Cognitive Impairment, Bailey Carter
Honors College
With approximately 20% of Americans affected by obstructive sleep apnea (OSA), and over 30% of sleep apneic patients non-compliant with the most common form of treatment, CPAP (Continuous Positive Airway Pressure), the proposed study looks to investigate the relationship between OSA, CPAP-compliance, and cognitive decline associated with many aging-related neurodegenerative diseases [1, 2]. Our group has performed in-home sleep studies using a patented, sensor mattress-sheet device, and standard actigraphy. Demographics including a questionnaire on OSA compliance and neurocognitive tests were administered to participants between 62 and 90 years of age. Cognitive decline meeting criteria for MCI (Mild Cognitive Impairment, the …
Identifying The Link Between Non-Coding Regulatory Rnas And Phenotypic Severity In A Zebrafish Model Of Gmppb Dystroglycanopathy, Grace Smith
Honors College
Muscular Dystrophy (MD) is characterized by varying severity and time-of-onset by individuals afflicted with the same forms of MD, a phenomenon that is not well understood. MD affects 250,000 individuals in the United States and is characterized by mutations in the dystroglycan complex. gmppb encodes an enzyme that glycosylates dystroglycan, making it functionally active; thus, mutations in gmppb cause dystroglycanopathic MD1 . The zebrafish (Danio rerio) is a powerful vertebrate model for musculoskeletal development and disease. Like human patients, gmppb mutant zebrafish present both mild and severe phenotypes. In order to understand the molecular mechanisms involved, we performed high-throughput RNA …

Characterization Of Ncf1 Mutants In A Zebrafish Model Of Innate Immune Function With Human Influenza A Virus Infection, Lily Charpentier
Honors College
Seasonal influenza A virus (IAV) infections and their associated respiratory diseases are the cause of an estimated 650,000 deaths each year, according to the World Health Organization. The zebrafish (Danio rerio) is a powerful vertebrate model to study innate immune function and host-pathogen interactions as the function of neutrophils and other phagocytes can be characterized in vivo. Preliminary studies have shown an increase in neutrophil respiratory burst activity to eliminate the invading pathogen, yet little is known of all of the mechanisms involved in neutrophil function. The NADPH oxidase complex, of which neutrophil cytosolic factor 1 (Ncf1) is a key …
In Vivo Imaging Of The Respiratory Burst Response To Influenza A Virus Infection, James Thomas Seuch
In Vivo Imaging Of The Respiratory Burst Response To Influenza A Virus Infection, James Thomas Seuch
Honors College
The CDC estimated that seasonal influenza A virus (IAV) infections resulted in 490,600 hospitalizations and 34,200 deaths in the US in the 2018-2019 season. The longterm goal of our research is to understand how to improve innate immune responses to IAV. During IAV infection, neutrophils and macrophages initiate a respiratory burst response where reactive oxygen species (ROS) are generated to destroy the pathogen and recruit additional immune cells. While ROS molecules, such as hydrogen peroxide, help clear the virus, the signaling cascade can also lead to excess neutrophil recruitment, hyperinflammation, and tissue damage. Regulatory mechanisms that trigger overactivation of neutrophils …
The Functional Role Of Glia In Peripheral Metabolic Tissue, Emma Paradie
The Functional Role Of Glia In Peripheral Metabolic Tissue, Emma Paradie
Honors College
With the ever-growing pandemic of obesity comes a multitude of consequential morbidities, such as increased risk of heart disease and type II Diabetes Mellitus. Secondary to diabetes is diabetic neuropathy, the regression or dying back of nerves that often occurs in the extremities, leading to loss of sensation or pain. Additionally, aging is a risk factor for obesity, diabetes, and neuropathy. Responsible for the communication between the extremities and peripheral tissues, such as adipose (fat), and the brain, is the peripheral nervous system. The peripheral nervous system is the umbrella under which varying types of nerves are designated, including sympathetic, …
A Biogeographical Assessment Of Arctic Marine Fungi, Bentley E. Simpson
A Biogeographical Assessment Of Arctic Marine Fungi, Bentley E. Simpson
Honors College
Marine fungi play a crucial role in recycling nutrients and channeling energy to higher trophic levels in the world oceans. Despite their critical role, their distributions and community composition, particularly in the Arctic, are largely unknown. This study reveals depth-related trends of abundance, diversity, and community composition of Arctic marine fungi through analysis of data obtained in the Tara Oceans expedition. With samples from surface (0-50 m), deep chlorophyll max (50-200 m), and mesopelagic (200-1000 m) depths, relative abundance, operational taxonomic unit (OTU) richness, and diversity were found to increase as a function of depth. Basidiomycota and Ascomycota were found …
