Diet Quality And Quality Of Life Among People With Parkinson’S Disease, Elizabeth Tierney

Open Access Master's Theses

Poor diet quality (DQ) and reduced quality of life (QoL) are concerns for people with Parkinson’s disease (PwPD). Non-motor (NMS) and motor symptoms (MS) significantly impact the DQ and QoL of PwPD which can be alleviated through diet intervention. This study examined the relationship between DQ and QoL in PwPD and investigated participant perspectives to identify themes related to nutrition care. This was a secondary data analysis of EMPOWER PD. Diet intake was assessed via the Dietary Screening Tool (DST). Quality of life was assessed by the Parkinson’s Disease Questionnaire-39-item (PDQ-39). Participant perspectives were collected through 1:1 interviews. Nineteen participants …

Evaluating Yield And Quality Of Heat-Tolerant Broccoli Varieties For Rhode Island Farmers, Calla Pederson

Open Access Master's Theses

In the United States, broccoli is a popular vegetable, important for its nutrition and economic contributions alike. However, its future production is at risk as broccoli prefers cooler climates, with an optimal temperature range of 15 - 23°C (59 - 73°F) for growth, especially in the weeks leading up to harvest. Temperatures above this threshold lead to failure to develop, damage, and unmarketability. There has also been an emphasis on bringing broccoli production back to the East coast from California, as climate events threatened Californian agriculture and local food has become popular, necessitating outside of season broccoli production during times …

Characterization Of Methodological Variability In Compound Specific Isotope Analysis Of Amino Acids (Csia-Aa), Audreyana Brown-Nash

Open Access Dissertations

The use of isotopes in the natural sciences stems from the principle that chemical reactions predictably alter the isotopic composition of a given sample. Recent advances in compound specific isotope analysis of amino acids (CSIA-AA) have paved the way for studies of increasingly complex ecological relationships, including the identification and characterization of organismal physiology, consumer-resource linkages, biogeochemical cycling, and movement ecology. The analytical power of CSIA-AA has caused an exponential increase in the number of application-based studies since its inception in the 1990s. With the technique constantly evolving to accommodate new research goals, it is important to understand how variation …

Big Cells, Big Impact: Unravelling Seasonal Patterns Of Net Primary Production In Narragansett Bay, Dominique Jae Lockwood

Open Access Master's Theses

Net primary production is a measurement of available energy, or the amount of biomass that phytoplankton produce during photosynthesis that fuels marine food webs and drives carbon cycling. Despite its ecological importance, net primary production is relatively understudied in comparison to chlorophyll-a, which is often used as a proxy for biomass rather than productivity. In this study, we measured size-fractionated net primary production and chlorophyll-a concentrations in Narragansett Bay over a 14-month period from January 2022 to February 2023. Weekly surface water samples were collected and filtered to distinguish between small (> 10 μm) and large ( …

Associations Between Dietary Sodium And Potassium Intakes, Urinary Sodium And Potassium Excretion And Blood Pressure Among Adult Females In Oromia Region, Ethiopia, Fred Baffour Addo

Estrogen Receptor-Mediated Effects Of Resveratrol On Muscle Function, David Ayi-Bonte

Open Access Master's Theses

Artemis missions are set to send the next man and the first woman back to the moon and enable long-term missions on the lunar surface. However, exposure to lunar gravity has significant physiological effects characterized by loss of muscle mass, weakness and decreased bone density. Nutraceutical countermeasures such as Resveratrol (RSV), a naturally occurring polyphenol, have been identified as promising strategies to preserve musculoskeletal health; however, its pleiotropic effect hinders our ability to identify the primary cellular pathways through which it delivers its benefits. Furthermore, its efficacy in simulated lunar gravity is unknown. Based on the benefits observed with RSV …

Ultra-Processed Food Intake And Dietary Intake Behaviors In Young Adults, Alexandra Black Larcom

Open Access Dissertations

Ultra-processed food (UPF) intake has been positively associated with adverse health outcomes and poor diet quality (DQ). UPFs tend to be of lower nutritional quality (NQ) than less processed foods, though NQ varies widely within each category of food processing. Young adults are the highest consumers of UPF, but UPF intake and related behaviors have not been examined in college students, a key subset of young adults. UPF overconsumption at meals has been proposed as a mechanism for the association between UPF intake, poor DQ, and adverse health outcomes, though no existing studies have considered NQ. Further, consumer understanding of …

Asexual, in-situ coral propagation offers a biologically viable path for restoration at depth. However, current ROV systems are not optimized for the delicate, fine-scale interactions required to perform this process reliably. The objective of this research was to design, prototype, and evaluate a ROV-mountable toolset capable of preparing octocoral fragments for potting in epoxy substrate, with the additional goal of integrating the toolset into URI’s Coral Carousel …

Molecular Interactions Between The Shellfish Pathogen Vibrio Coralliilyticus Re22 And The Probiont Phaeobacter Inhibens S4sm, Jessica Coppersmith

Open Access Dissertations

Oyster larvae aquaculture is an important industry, both economically and environmentally, helping to create sustainable food systems by supplying seed oysters to farms, and also to restoration projects aimed at building coastal resilience and improving water quality by rejuvenating wild populations. However, oyster larvae are highly susceptible to rapid mortality events, crashes, which can seriously impact the industry. One source of these crashes in hatchery systems is vibriosis, caused by pathogenic species of Vibrio bacteria that are ubiquitous in temperate coastal waters, and with rising surface water temperatures their prevalence and virulence are increasing. To prevent these larval crashes from …

Applying Neuroscience To A Brief In-Class Activity: A Trauma-Informed Quick Fix To Support Students Through Sensitive Content, Jessica Cless

Quantifying Links Between Phytoplankton Physiology And The Environment, Gabrielle M. Armin

Open Access Dissertations

Phytoplankton are microscopic, primary producers in aquatic ecosystems worldwide. They are key links in global biogeochemical cycles, converting inorganic compounds into bioavailable nutrients which fuel fisheries. Through photosynthesis, phytoplankton play an essential role in the carbon cycle and marine biological pump, drawing carbon from the atmosphere, which is eventually sequestered in the oceans, regulating our Earth’s climate. Due to their influential role in large scale processes, there have been many efforts to characterize and quantify phytoplankton impacts to ecosystem health and global nutrient cycles. Often, phytoplankton physiology has been highly simplified in global or ecosystem models, limiting their representation to …

Intersections Of Inattention: A Qualitative Inquiry Into The Experiences Of Multiply Marginalized Students In Community College Settings, Jana N. Knibb

Open Access Dissertations

Educational research has examined the impact of expanded access to higher education for historically marginalized groups. However, research on the experiences of students who are both racially minoritized and dis/abled is limited. Findings suggest that, due to their intersectional identities, multiply marginalized dis/abled students (MMDS) navigate policies and practices related to racist ableism, which further marginalize them and create additional barriers in their higher education experiences. Expanding this research requires theoretical frameworks that account for students' identities, experiences, and barriers in higher educational spaces and contexts. This qualitative study, grounded in Dis/ability Studies and Critical Race Theory in Education (DisCrit), …

Quantifying Mixotrophy Potential As A Function Of Environmental And Biological Drivers In Coastal And Estuarine Plankton Communities, Erica Ewton

Open Access Dissertations

The discovery of mixotrophic plankton has bridged gaps in nutrient cycling budgets and altered the understanding of food webs and energy transfer. Mixotrophic plankton are capable of simultaneous or sequential photosynthesis and heterotrophy, providing multiple avenues of nutrition and thus reducing limitations that affect specialists. These energy dense cells provide increased biomass for higher trophic levels, which may increase organism sizes throughout the food web. Additionally, they may be physically denser, which alters biogeochemical cycling including carbon sequestration. The work presented here uses LysoTracker Green, an acidotropic stain that attaches to phagocytic vacuoles within potentially phagotrophic small (< 20 µm diameter) phytoplankton communities (‘mixoplankton’), to better understand their abundance, relative abundance, and growth rates in relation to the matrix of natural conditions they inhabit. Understanding the prevalence and drivers of mixoplankton is vital to better parameterize biogeochemical cycling and energy transfer in the ocean and for models that predict the fate of future oceans.In the first study, I compared the abundance of mixoplankton in the Northeast U.S. Shelf (NES) and Coastal California Current System (CCS) during two cruises in the NES in summer 2021 and one cruise in the CCS in summer 2022. These two contrasting coastal systems span the breadth of environmental conditions observed in temperate marine ecosystems and thus provided an opportunity to examine indicators of mixoplankton across temperate coastal regions. I discovered higher mixoplankton abundance in the NES than CCS yet similar population sizes of nanoeukaryotic photosynthesizers, resulting in higher relative abundance of mixoplankton in the NES than CCS. Across both systems, I found increased mixoplankton abundance associated with decreasing temperature and combined nitrate + nitrite concentrations (N+N), and increasing light intensity and Synechococcus abundance …

Per- And Polyfluoroalkyl Substances (Pfas) Effects On Tissue Disposition, Proteome, And Health Effects, Juliana Agudelo Areiza

Open Access Dissertations

Per- and polyfluoroalkyl substances are a class of nonbiodegradable synthetic aliphatic environmental toxicants that are ubiquitous in the environment. A small subset, specifically perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), have been designated as highly hazardous to human health by the Environmental Protection Agency (EPA) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). PFOA and PFOS-associated adverse health effects include, but are not limited to, immune suppression, thyroid dysfunction, increased serum cholesterol, liver damage (i.e., alanine aminotransferase (ALT)), and developmental toxicity (i.e., low fetal birth weight and neurotoxicity). In this doctoral dissertation, it was hypothesized that environmental PFAS …

A Socio-Ecological Investigation Of Ulithian Spearfishing, Joshua Pi

Open Access Dissertations

Coral reef socio-ecological systems (SESs) characterize the interconnected relationships between coral reef ecosystems and reef-dependent communities. One such SES exists in Ulithi Atoll, Federated States of Micronesia, where Ulithians fish, steward, and govern their reefs through customary marine tenure, traditional ecological knowledge, and cultural taboos. In recent decades, rapid modernization in Ulithi has introduced new fishing technologies, transformed fishing practices, and ultimately reshaped the functioning of Ulithi’s traditional SES. One significant change was the introduction of spearfishing during the mid-20^th century, which is more selective and individualistic compared to other community-centric fishing methods that have existed for generations. This …
