Assessment Of Microbial Quality And Safety, Including Aflatoxin B1, In Buckwheat Flour And Groats, La Fontaine Bahatsi

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Buckwheat (Fagopyrum esculentum), a gluten-free pseudocereal, has gained popularity in global food markets for its nutritional value and functional properties. However, despite its health-promoting potential, buckwheat is vulnerable to microbial contamination and mycotoxin accumulation during cultivation, processing, and storage. These factors present significant food safety concerns that remain understudied, particularly in North America.

This study investigated the microbiological quality and mycotoxin contamination of buckwheat flour and groats collected from different suppliers via online sourcing. Samples were collected in two consecutive years (2024-2025). Microbiological quality, including aerobic plate counts (APC), Enterobacteriaceae, coliforms, E. coli, yeasts, and molds, was evaluated …

Recombinant Erythropoietin Use For Anemia Of Prematurity: A Three Year Since Center Experience, Hannah Darland, Krishna Dummula, Chaitali Mahajan, Vishal Pandey

Posters

Background: Anemia is a common disorder of prematurity secondary to limited blood volume, excessive blood draws, inadequate nutrition, poor iron reserves, and insufficient endogenous erythropoietin. While many NICUs use recombinant erythropoietin (rEpo) to treat anemia of prematurity, the absence of universal guidelines has led to variability in dosing and schedules. Here we present our experience on the use of rEpo in a level 3 NICU. Our unit protocol uses 400 IU/kg three times a week for a total of 9 doses if hematocrit < 30%. Objectives: The purpose of this study was to evaluate the response to rEpo in infants with anemia of prematurity. Methods: Charts of infants born between 2018 and 2020 with gestation ≤34 weeks who received rEpo for anemia of prematurity were retrospectively reviewed. We defined response to therapy as an increase of hematocrit by 5% from pre-treatment baseline. Infants who did not achieve the therapeutic goal or who received blood transfusions were considered non-responders. Neutropenia, thrombocytopenia, and retinopathy of prematurity (ROP) requiring treatment were treated as adverse events. Results: A total of 44 infants were treated with rEpo during the study period. Clinical characteristics are described in Table I. Average hematocrit at birth was 44.8±7.5 (32.7 to 60.8). Infants were started on rEPO at a median corrected age of 33.3 ±3 weeks and a weight of 1674±622 g. Average DOL was 37±18 at initiation of therapy. Average baseline hematocrit at the start of therapy was 27.9±1.8%. 80% of patients (35/44) responded with increase of hematocrit by >5%, 20% (9/44) did not respond. 75% of infants (33/44) received all 9 doses. 11 patients received …

Evaluating The Effects Of Agricultural Management Practices On Beneficial Arthropod Communities, Isaac Newton Ativor

Doctoral Dissertations

Arthropods provide essential ecosystem services to our agricultural landscapes. These ecosystem services include biological control of pest organisms, including weed seeds, and plant pollination. Concerningly, however, there has been a global decline in insect populations over the last decade, a major cause of which is agricultural intensification. Previous research has demonstrated that agricultural management practices can strongly influence the species composition and abundance of arthropod communities, and therefore presumably the ecosystem services or disservices these organisms provide; however, our understanding of these interactions remains limited. I conducted three studies to investigate whether agricultural practices common in annual row crop (tillage …

Applications Of Urban Forestry: Advancing Environmental Justice Via Tree Planting In New York City, Newell Alexandra Blanton

Student Theses 2015-Present

NYC’s urban forest is composed of 7 million trees and the infrastructure which supports them. These trees have incredible value in almost every sense of the word; they provide essential ecosystem services such as climate modification and air purification that are otherwise impossible or enormously costly to manage. Contrarily, a lack of tree coverage in an urbanized area can contribute negatively to the health, economics, and overall quality of life for a neighborhood’s residents. This paper analyzes the impact trees have in New York City through a socioeconomic lens by comparing tree metrics and their collective influence in various neighborhoods, …

Temporal Variability In The Bulk Nutritional Quality Of Estuarine Plankton, Marley Gonsalves

Master's Theses and Capstones

The temporal variability of plankton is well documented, particularly in constantly changing tidal systems such as estuaries, but the extent to which this variability applies to plankton nutritional quality is less well known. As the base of the aquatic food web, variation in phytoplankton nutritional quality stands to constrain fishery production, particularly of filter-feeders. Here, community and nutritional data was collected from Great Bay, NH, a model estuary, over seasonal, tidal, and daily time scales to identify the range and variability of nutritional quality in plankton. Bulk spectrophotometric neutral lipid and protein measurements were compared to plankton community composition data …

Effects Of Gibberellic Acid (Ga3) And Cluster Thinning On Fruit Quality, Cluster Quality And Yield In Seedless Table Grape Cultivars, Radhika Rani

Master's Theses and Capstones

Seedless table grape production in cool-climate regions like the Northeastern U.S. is limited by cold temperatures, short growing season, and relatively few adapted cultivars. American species (Vitis labrusca) or interspecific hybrids offer more disease and cold resistance as compared to European species (V. vinifera), however, small berry size, lower yields, and low fruit quality have been some of the limitations for these cultivars. This study evaluated the effects of gibberellic acid (GA3) and cluster thinning under different training systems to improve cluster and berry quality in seedless table grape cultivars. The first experiment focused on ‘Concord Seedless’, examining the effects …

Modeling Ungulate Population Parameters Across Human-Modified Landscapes, Sarah Richard

Master's Theses and Capstones

As human activity and development continue to alter natural landscapes, large ungulates are increasingly exposed to changing habitat structures, altered mortality risks, and climate-related stressors. These ecological shifts can influence their survival, behavior, and population dynamics. Understanding how such complex and evolving conditions shape demographic trends in these species is critical for effective management. In this thesis, I examined two ecologically and culturally important ungulate species, white-tailed deer (Odocoileus virginianus) and moose (Alces alces), across human-modified environments. Specifically, I analyzed how intrinsic factors, behavioral development, and landscape composition influence stage-specific mortality in deer neonates and population parameters in moose in …

Blockbusters Or Blind Spots? A Critical Look At Poverty, Bullets And Bandits Narratives In Latin American Cinema, Carlos Fernández-Rodríguez, Elio Quiroga Rodríguez, Luis M. Romero- Rodríguez

Artículos científicos

Historically, the cultural industries of the Global South have been relegated in the face of North American and European production predominance. In Latin America, the most internationally successful audiovisual productions, both at the cinema ticket window and festivals, usually deal with stereotypes of extreme poverty, rurality, delinquency, terrorism, and drug trafficking, which, in the collective imagination of foreign audiences, promote an exaggerated representation of the region's social problems, contributing to xenophobia, hate speech, and anti-migration discourses in countries in the Global North. This study conducts an analysis of five emblematic feature films of Latin American cinema: Cidade de Deus [ …

Helminth And Malaria Co-Infection Among Pregnant Women In Battor And Adidome Towns Of The Volta Region Of Ghana, Navneet Kaur, William K. Anyan, Abraham K. Anang, Nilanjan Lodh

Clinical Lab Sciences Faculty Research and Publications

Aim: In sub-Saharan Africa, approximately 40 million pregnant women are exposed to parasitic diseases such as malaria caused by Plasmodium falciparum, Schistosome parasites, and soil-transmitted helminths (STHs). When parasitic diseases share the same habitat and overlap in distribution, then high co-infection rates occur. The co-infection can lead to consequences for the child, such as intrauterine growth retardation, low birth weight, pre-term delivery, and neonatal mortality.

Methods: The objective of the study was to determine the nature and extent of coinfection from 100 samples collected from the Battor (50) and Adidome (50) towns of Ghana in collaboration with the Noguchi …

Effect Of Workplace Design On Collaboration And Satisfaction In Space System Command, Joshua A. Hagood

Theses and Dissertations

This study addresses a significant knowledge gap regarding the influence of physical workplace design on employee collaboration and satisfaction with the physical environment within U.S. Space Force technical military organizations.  While seminal industry research consistently demonstrates that physical design and indoor environmental quality influence employee satisfaction and collaboration (e.g., Candido et al., 2015; Sailer et al., 2021), the understanding of these impacts within military contexts remains limited.  Using a quantitative post-occupancy evaluation survey, adapted from the Sustainable Post Occupancy Evaluation Survey (SPOES), multiple regression analyses revealed that physical elements collectively predict both satisfaction and collaboration.  The final simplified model showed …

Heart failure with preserved ejection fraction (HFpEF) accounts for ∼50% of HF cases. The ZSF1-obese rat model recapitulates clinical features of HFpEF including hypertension, obesity, metabolic syndrome, exercise intolerance, and diastolic dysfunction. We utilized a systems-biology approach to define the metabolic and transcriptional signatures to gain mechanistic insight into pathways contributing to HFpEF development. Male ZSF1-obese, ZSF1-lean hypertensive controls, and WKY (wild-type) controls were compared at 14 weeks of age for extensive physiological phenotyping and left ventricle (LV) tissue harvesting for unbiased-metabolomics, RNA-sequencing, and mitochondrial morphology and function. Utilizing ZSF1-lean and WKY controls enabled a distinction between hypertension-driven molecular changes …

Impact Of Varied Dietary Macronutrient Ratios On The Nutrition Status Of Swiss Albino Mice, Hellen Kinyi, Charles Kato, Gertrude Kiwanuka

Biomedical Sciences, East Africa

The nutrition status of an organism depends on the balance between nutrient intake and utilization. Malnutrition results not only from inadequate caloric intake but also from imbalanced macronutrient ratios, which can affect aging, metabolism, and health. While many studies focus on individual nutrients, this study used purified, isocaloric diets with varying macronutrient ratios to assess dietary effects on nutrition markers in Swiss albino mice.

Mice were randomized into 6 dietary groups, each containing 6 males and 6 females housed separately. Each group received an isocaloric diet with different carbohydrate, protein, and lipid ratios for 15 weeks. Animal weight, body mass …

A Mixed-Methods Approach To Describe Typologies And Fiber Consumption Patterns Of Hispanic/Latino Adults Grouped Using Cluster Analysis, Nicholas Clarke

Master's Theses and Capstones

AbstractBackground: Hispanic/Latino adults in the United States experience disproportionate rates of obesity and diet-related chronic diseases yet remain underrepresented in obesity research. Traditional “one-size-fits-all” nutrition interventions have demonstrated limited effectiveness in this population, largely due to substantial heterogeneity in cultural, socioeconomic, and behavioral factors that influence dietary patterns. Objectives: The overarching goal of this project was to further characterize previously identified subgroups within the Hispanic/Latino population to provide a foundation for future tailored interventions that address the specific needs and preferences of these subpopulations. Specific aims were to: 1. Describe cluster typologies using a virtual nominal group technique (vNGT) with …

Toxin-Producing Cyanobacteria In Green Manure Microbiomes, Alyssa Nicole Daigle

Master's Theses and Capstones

The increasing reliance on inefficient synthetic fertilizers, which readily leach from soils and contribute to downstream pollution, underscores the urgent need for more sustainable nutrient sources, such as green manures (GMs). Floating aquatic plants like duckweeds are particularly promising candidates due to their natural abundance, rapid growth rates, and ability to efficiently uptake nutrients. However, the presence of toxin-producing cyanobacteria in duckweed microbiomes raises concerns about the potential for toxin accumulation, like microcystins (MCs), both in the GM biomass and in the edible crops to which it is applied. To evaluate the suitability and safety of duckweed-based GMs, we conducted …

Host Evolutionary History As A Predictor Of Microbiome Breeding Success, Ciana Lazu

Master's Theses and Capstones

Microbial inoculants present a potential alternative to artificial fertilizers and other chemical products in agriculture, yet microbial products derived from non-native microbes may pose ecological risks or fail to thrive. On the other hand, creating microbial inoculants from local microbes via “microbiome breeding” can be unpredictable. Here, the aquatic plant Lemna minor (duckweed), microbes isolated from duckweed, and microbes isolated from other, co-occurring aquatic plants was used to evaluate if the evolutionary distance between hosts from which microbes are sourced is a predictor of the success in “breeding” locally derived microbiomes to promote duckweed growth. “Microbiome breeding” was performed on …

Laying The Foundation For A Tartary Buckwheat Breeding Program For The Northeast: Phenotypic Characterization Of Seedling Traits And Hybridization Techniques, Julia Oliveira Barreiro De Jesus

Master's Theses and Capstones

Tartary buckwheat (Fagopyrum tataricum) is an underutilized crop with the potential to address key challenges in modern agriculture, including food security in the context of climate change and growing resource scarcity. It is valued for its tolerance to abiotic stresses such as drought, cold, and marginal soils, making it a promising candidate for cultivation in the Northeastern United States, a region where average temperatures have risen by approximately 0.25 °C per decade since 1970. These climatic shifts have led to changes in snow-to-rain ratios, earlier phenological events, and increased intensity of precipitation events, particularly in spring, posing challenges for early …

Increasing The Knowledge Base Of A Novel Fruit Crop, Actinidia Arguta, To Promote Adoption In The Northeastern United States, Zoe Rose Robinson

Master's Theses and Capstones

The unique attributes of kiwiberry (Actinidia arguta (Siebold et Zucc.) Planch ex. Miq) make it a promising high-value fruit crop for the Northeastern United States, although not widely grown in the region. As discussed in Chapter 1, it is likely that some of the barriers to kiwiberry diffusion in the Northeast include basic research gaps (e.g. crop physiology, management, and enterprise analysis), and a lack of farmer-to-farmer communication channels. To address some of these barriers, this thesis reports the results of a Northeast commercial kiwiberry growers survey to provide a portrait of current regional kiwiberry production, and experiments to determine …

A Co-Design Approach To Integrating Gender Into The Cacao Value Chain In Davao City, Philippines, Mia Barbara Aranas, Aileen Lapitan, Mitchiko Lopez, Nico Jayson Anastacio, Canesio Predo, Mara Faylon, Emmanuel Flores, Claire Estelle Cruz, Anjelyn Joy Enong

The Philippine Agricultural Scientist

The specific needs and challenges of women and their contributions are often not integrated when developing interventions and policies targeted to improve agricultural value chains. Therefore, this study developed a codesign approach to creating solutions to improve gender relations in agri-food value chains. Specifically, it focused on the cacao value chain in Davao City, which is located in the southern Philippines. Co-design is a highly participatory approach in which solutions are designed with, and not just for, the people who have lived experiences of the problems being addressed. The approach emphasizes understanding gender-related barriers and opportunities to inform government interventions …

Crispr-Cas9 Gene Editing In Tomato: Development And Characterization Under Stress, Jun Guo

Tennessee State University Alumni Theses and Dissertations

Transcription factor (TF) families played essential roles in plant responses to abiotic stress, contributing significantly to stress tolerance and adaptation. The basic helix-loop-helix (bHLH) TF family included 161 members in tomato (Solanum lycopersicum). Previous proteomic analysis identified TF bHLH148 (Solyc01g058670) as being upregulated under aluminum (Al) stress, suggesting a potential role in Al tolerance. To investigate this, CRISPR-Cas9 was used to generate SlbHLH148 knockout mutants in the ‘Black Vernissage’ tomato cultivar. Two homozygous T2 lines, Slbhlh148-1 and Slbhlh148-2, were confirmed to contain frameshift mutations that resulted in truncated proteins lacking the bHLH_AtIBH1_like domain, as shown by protein modeling. Phenotypic evaluation …

Challenges In Providing Equitable Education For Primary School Students With Learning Disabilities In Zimbabwe: Teachers’ Experiences., Joyce Madzinga

Dissertations

This study examines the challenges primary school teachers in Zimbabwe face when supporting students with learning disabilities (LDs). Many learners with LDs are excluded from adequate classroom support due to systemic, cultural, and resource limitations. Learning disabilities are often under-recognized as compared to other disabilities because they are invisible. Raising awareness and empowering educators are crucial steps toward addressing these hidden needs and ensuring they are recognized and met. Six teachers were interviewed using a qualitative ethnographic approach. Findings reveal obstacles, including insufficient training in special education, limited teaching resources, high pupil-teacher ratios, negative societal attitudes, and poverty-related constraints. Additional …

Racial Moderation Of Infant Mortality Risk And Protective Factors In The United States, Temitope Oluwaseun Akinsola

Walden Dissertations and Doctoral Studies

The rate of infant mortality is a pressing health issue in the United States, as ethnic minorities are disproportionately affected. This study addressed how race controls the predictive power of demographic, socioeconomic, and geographic factors on infant mortality. Using a quantitative correlational design, secondary data from 181 individuals listed in the CDC-National Vital Statistics System database were used, which contains nationally aggregated data related to infant mortality rates. Bronfenbrenner’s social ecological model guided the study, and multiple regression and moderation models were used to examine socioeconomic status and access to healthcare on infant mortality outcomes. Results indicated that race significantly …
