Characterizing Metabolic Flux Of Plant Secondary Metabolites From Diverse Animal-Source Foods To Humans, Muhammad Ahsin May 2026

Characterizing Metabolic Flux Of Plant Secondary Metabolites From Diverse Animal-Source Foods To Humans, Muhammad Ahsin

All Graduate Theses and Dissertations, Fall 2023 to Present

There is a popular saying: “You are what you eat.” But does this also mean, “You are what your food eats”? This dissertation explores that question by examining how farming practices shape the nutritional quality of meat—and what, if anything, those differences mean for the people who consume it. While modern livestock production and nutrition research often emphasize protein and fat, this work tests the idea that animals function as biological mediators, linking soil and plant conditions to human diets through the chemical composition of meat and milk. To evaluate this hypothesis, we tracked health-relevant plant compounds— phytonutrients—across the soil–plant–animal–human …

Dyadic Agreement In And Task Correlates To A Measurement Of Conversational Success, Samantha Budge

All Graduate Theses and Dissertations, Fall 2023 to Present

Successful conversation matters for social connection, wellbeing, and quality of life, but people do not always agree on whether a conversation was successful, even when they participated in the same interaction. Conversation is also commonly measured through task success, even though it’s unclear how task success correlates to how successful a conversation feels. This study examined how conversational success is experienced by different conversation partners and whether feeling successful in a conversation is related to how well a task is completed.

Participants took part in a structured conversational task and then rated their own conversational experience using a self-report questionnaire …


Food-Form Delivery Of Spore-Forming Probiotics As An Alternative To Gavage In Animal Models, Aubreyona Faith Migliori Skalka May 2026

Food-Form Delivery Of Spore-Forming Probiotics As An Alternative To Gavage In Animal Models, Aubreyona Faith Migliori Skalka

All Graduate Theses and Dissertations, Fall 2023 to Present

Western dietary patterns are characterized by nutrient-poor, calorie-rich diets and have been linked to poor health outcomes and gut inflammation phenotypes. Probiotics are often taken to support gut health, but many beneficial bacteria do not survive transport through the digestive system to produce any effect. Spore-forming bacteria, such as Bacillus coagulans, are more resilient due to their hardy outer coat which aids in survival through many obstacles encountered in the gastrointestinal tract, including acidic stomach conditions. In research studies, probiotics are usually given to mice through a procedure called oral gavage, where a tube is used to deliver the …


Paucilactobacillus Wasatchensis Gas Production In Cheddar Cheese Through Symbiotic Amino Acid Metabolism With Lactococcus Lactis Starter Cultures, Niharika Mishra May 2026

Paucilactobacillus Wasatchensis Gas Production In Cheddar Cheese Through Symbiotic Amino Acid Metabolism With Lactococcus Lactis Starter Cultures, Niharika Mishra

All Graduate Theses and Dissertations, Fall 2023 to Present

Cheese is popular for its rich sensory notes and desirable physical attributes; however, the late blowing gas defect in cheddar cheese disrupts its appearance and can undermine its commercial value, for example if the late gas defect is severe, the block can crumble upon cutting, increasing cutting losses from 10% (non-defective) up to 50% (Donnely et al., 2014).

Paucilactobacillus wasatchensis cannot survive pasteurization (McMahon, D. J., et al., 2020); therefore, it enters the cheese as a contaminant during the cheesemaking process. Cheesemaking occurs in three stages: (1) curdling of milk by acidification through starter cultures, (2) separation of curd from …


Impact Of Inhibiting Mitochondrial Calcium Uptake On Calcium Homeostasis And Postmortem Metabolism In Porcine Muscle, Fatema Rahaman Mishu May 2026

Impact Of Inhibiting Mitochondrial Calcium Uptake On Calcium Homeostasis And Postmortem Metabolism In Porcine Muscle, Fatema Rahaman Mishu

All Graduate Theses and Dissertations, Fall 2023 to Present

After harvesting the animal, pork muscle continues to undergo changes as it turns from muscle into meat. During this early period, the muscle uses up energy and produces acid, which lowers pH and can affect important quality traits such as color and how well the meat holds water. A key driver of these early changes is calcium, a natural mineral inside muscle cells that helps control contraction and energy use. In this study, we tested whether mitochondria (the cell’s “powerhouse”) help control calcium after harvest and, in turn, influence early postmortem changes in pork. We used a research compound (DS16570511) …

Staff Education On The Implementation Of Walking Interventions, Cynthia Ononobi Apr 2026

Staff Education On The Implementation Of Walking Interventions, Cynthia Ononobi

Walden Dissertations and Doctoral Studies

The doctoral project was a staff education project aimed at improving the knowledge of psychiatric nurses on the use of structured walking interventions to manage depression. The practice problem was related to the lack of consistency in the application of walking as a treatment for depression. This gap was significant to address because psychiatric nurses are in the center of behavioral activation, and insufficient knowledge may deny patients the right to potentially valuable, affordable, and nonpharmacological treatment. The practice-based question was: Among psychiatric nursing staff does education on structured walking intervention, compared to standard care, improve staff knowledge and skills …

Occupational Stressors And Health Impacts Among First Responders, Mason N. Roach

Honors College Theses

The United States 911 emergency response system is an interconnected web of public services that seeks to provide its community with care, resources, and safety in times of need. However, the impact of this support on the employees providing the service often goes unnoticed. This review identifies and analyzes the unique strains on first responders' physical and mental health using the Job Demand-Control Model and the Allostatic Load Model. A review of available research literature supports the conclusion that occupational-related stress, including trauma exposure, shift work, poor leadership, and inadequate communication, can have long-lasting negative impacts on provider health.


Quantitative Fluorescence Imaging Using A Paired Agent Approach For Improving Surgical Decision Making, Sanjana Pannem Apr 2026

Quantitative Fluorescence Imaging Using A Paired Agent Approach For Improving Surgical Decision Making, Sanjana Pannem

Dartmouth College Ph.D Dissertations

Surgical resection remains to be the cornerstone of treatment for most solid tumors, where the primary objective is to remove all visible and microscopic disease. However, the extent of tumor resection is inherently limited by the surgeon’s ability to distinguish tumor from normal tissue, intraoperatively. As a result, positive surgical margins (PSM), where residual tumor remains after surgery, are a common occurrence and are associated with increased recurrence, need for adjuvant therapies, dismal patient outcomes, and high healthcare costs.

Fluorescence guided surgery (FGS) has emerged as a promising technique to enhance intraoperative visualization of tumors and may help reduce the …


Investigating The Synthesis And Antibacterial Activity Of A Main-Chain Cationic Polymer, Emily Smith Apr 2026

Investigating The Synthesis And Antibacterial Activity Of A Main-Chain Cationic Polymer, Emily Smith

Honors Theses

Antibiotic resistance is a growing threat to public health. Due to the overuse of antibiotics in agriculture, the overprescription of antibiotics, and the misuse of antibiotics by patients, antibiotic resistance is spreading at an alarming rate. As antibiotic resistance spreads, the antibiotics we depend on to treat common infections become ineffective. Therefore, it is imperative to develop novel treatments for infections that do not increase the prevalence of antibiotic resistance. One treatment being explored is the use of synthetic polymers with antibacterial properties. Synthetic polymers are advantageous because they can be synthesized from widely available precursors and their structure is …


Cleft Palate And The Coordination Of Wnt Signaling And Pax9 In Murine Palatogenesis, Landon Wyatt Apr 2026

Cleft Palate And The Coordination Of Wnt Signaling And Pax9 In Murine Palatogenesis, Landon Wyatt

Honors Theses

Cleft palate is a common craniofacial birth defect that arises when the molecular and morphogenetic events guiding secondary palate formation lose coordination during a narrow developmental window. In mice, successful palatogenesis requires the paired palatal shelves to grow vertically, elevate above the tongue, and fuse at the midline; disruption of any of these steps can result in clefting. Two important regulators of this process are canonical Wnt signaling and the transcription factor Pax9, both of which contribute to normal palatal mesenchymal growth and patterning during early development. This paper first examines whether altered Dkk1/Wnt signaling contributes to the Pax9-null palate …
