Development Of Enzyme-Responsive Polymersomes As A Drug Delivery System For Gm1 Gangliosidosis, Bipin Chakravarthy Paruchuri

All Dissertations

GM1 gangliosidosis is a lysosomal storage disorder caused by deficiency of β-galactosidase (βgal) and subsequent accumulation of GM1 ganglioside in lysosomes. The rare nature of this disorder presents challenges with prognosis and treatment. Enzyme replacement therapy (ERT) can effectively treat systemic deficiencies, but the intravenously administered enzyme cannot cross the blood-brain barrier (BBB) to treat the central nervous system. A delivery system to encapsulate and deliver the enzyme can facilitate enzyme transport across the BBB with suitable surface modifications. One of the pathological aspects of GM1-affected cells is the upregulation of the lysosomal enzyme hexosaminidase A (HexA). In this dissertation, …

An Epidemiological Synthesis Of Emerging And Re-Emerging Zoonotic Disease Threats In Cameroon, 2000-2022 And Community Stakeholder Mapping, Nancy Tahmo

Capstone Experience: Master of Public Health

Introduction: Population factors such as urbanization, socio-economic, and environmental factors are driving forces for emerging/re-emerging diseases in Cameroon, and the effects of these are experienced differently across demographics. Indigenous rainforest communities in the Congo Basin, for example, suffer worse health outcomes compared to neighboring communities, like the Pygmies, who have a life expectancy of 22 years less than neighboring Bantus. It is important to characterize the risk of exposure of these vulnerable communities and map out, through a systematic review, descriptive epidemiological data around zoonoses, to inform preparedness and research efforts.

Methods: Following the PRISMA guidelines, a protocol was registered …

Program Planning On Social Determinants Of Health For Rural Nebraska, Maria H. Cantu Hines

Capstone Experience: Master of Public Health

Social determinants of health (SDOH) are non-health factors that impact health in both direct and indirect ways. Research into SDOH and their effects has been extensive in recent years and has been further documented by the COVID-19 pandemic. Despite the wealth of the literature on the SDOH, awareness of these important factors is not prevalent among community residents. Rural communities are as subject to the impact of SDOH just as their urban counterparts and experience additional complexities related to geography and topography.

This capstone project aims to raise awareness, provide education, and assist with tools and resources, to empower rural …

Increasing Production Of Therapeutic Mabs In Cho Cells Through Genetic Engineering, Charles Barentine

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Low total energy expenditure (TEE, MJ/d) has been a hypothesized risk factor for weight gain, but repeatability of TEE, a critical variable in longitudinal studies of energy balance, is understudied. We examine repeated doubly labeled water (DLW) measurements of TEE in 348 adults and 47 children from the IAEA DLW Database (mean ± SD time interval: 1.9 ± 2.9 y) to assess repeatability of TEE, and to examine if TEE adjusted for age, sex, fat-free mass, and fat mass is associated with changes in weight or body composition. Here, we report that repeatability of TEE is high for adults, but …

Characterizing The Cutaneous Microbiome Of Eurycea Lucifuga As A Potential Defense Against Chytridiomycosis, Madeline Key

Senior Honors Theses

Chytridiomycosis is an emerging infectious disease that is significantly reducing global amphibian populations. The disease is caused by Batrachochytrium dendrobatidis (Bd), a fungus that lethally modifies amphibian skin. Recent research has suggested that the cutaneous microbiome of individual amphibians may play a role in susceptibility to the pathogen. In this study, twelve cave salamanders (Eurycea lucifuga) were collected. Cutaneous bacteria from each salamander were isolated and identified using Sanger Sequencing. Additionally, a Bd-challenge assay was performed to determine each isolate’s antifungal activity. Results indicated many microbial isolates possessed inhibitory capabilities against Bd, which may …

Worried Sick: Understanding The Implications Of Stress On A Physiological Level, Julia Saia

Senior Honors Theses

Stress is prevalent among many individuals in today’s society. A literature review was conducted to investigate the physiological effects of stress, including the biomarkers of stress and how these interact with various body systems. The stress response is a protective mechanism to prepare the body to adequately respond to a perceived threat. However, when this response is prolonged, it begins to have a maladaptive effect on the body and can cause more harm than good. This literature review sought to compile what is known regarding the general effects of chronic stress and its impact on the nervous, immune, digestive, and …

Raising Native Plant Awareness As A Method For Re-Naturalization, Meredith L. Haaker

Social Sciences

Humans are inseparable from the natural environment. We are one and the same, interconnected within the ecology of creation and care, not only destruction. By grounding ourselves in Indigenous wisdom and the principles of Traditional Ecological Knowledge, we are more able to recognize the important relational facets between humans and three native Californian plants (California black walnut, California blue elderberry, California bay laurel). In introducing Kimmerer’s concept of re-naturalization of humans, we can draw a connection to the same process a naturalized plant undergoes; immigration from a foreign place, dependence on the surrounding resources, and settlement of an area …

In rice ecosystems, seeding densities can be adjusted to compensate for lower nitrogen levels that reduce GHG emissions, or to increase farm profitability. However, density-induced changes to plant anatomy could affect herbivore-rice interactions, and alter arthropod community dynamics. We conducted an experiment that varied transplanting density (low or high), nitrogenous fertilizer (0, 60 or 150 kg added ha−1) and rice variety (resistant or susceptible to phloem-feeding insects) over two rice-growing seasons. Yields per plot increased with added nitrogen, but were not affected by variety or transplanting density. Planthopper and leafhopper densities were lower on resistant rice and in high-density field …

Background: Pro-opiomelanocortin (POMC) neurons play a sexually dimorphic role in body weight and glucose balance. However, the mechanisms for the sex differences in POMC neuron functions are not fully understood. Results: We detected small conductance calcium-activated potassium (SK) current in POMC neurons. Secondary analysis of published single-cell RNA-Seq data showed that POMC neurons abundantly express SK3, one SK channel subunit. To test whether SK3 in POMC neurons regulates POMC neuron functions on energy and glucose homeostasis, we used a Cre-loxP strategy to delete SK3 specifically from mature POMC neurons. POMC-specific deletion of SK3 did not affect body weight in either …

Predicting Energy Intake In Adults Who Are Dieting And Exercising, Corey Gerving, Robert Lasater, James Starling, Danielle M. Ostendorf, Leanne M. Redman, Chad Estabrooks, Kevin Cummiskey, Vincent Antonetti, Diana M. Thomas

Clinical Research Faculty Publications

Background: When a lifestyle intervention combines caloric restriction and increased physical activity energy expenditure (PAEE), there are two components of energy balance, energy intake (EI) and physical activity energy expenditure (PAEE), that are routinely misreported and expensive to measure. Energy balance models have successfully predicted EI if PAEE is known. Estimating EI from an energy balance model when PAEE is not known remains an open question. Objective: The objective was to evaluate the performance of an energy balance differential equation model to predict EI in an intervention that includes both calorie restriction and increases in PAEE. Design: The Antonetti energy …
