Valorization Of Seafood Waste For Food Packaging Development, Zhijing Zhan, Yiming Feng, Jikai Zhao, Mingyu Qiao, Qing Jin

School of Earth, Environmental, & Marine Sciences Faculty Publications

Packaging plays a crucial role in protecting food by providing excellent mechanical properties as well as effectively blocking water vapor, oxygen, oil, and other contaminants. The low degradation of widely used petroleum-based plastics leads to environmental pollution and poses health risks. This has drawn interest in renewable biopolymers as sustainable alternatives. The seafood industry generates significant waste that is rich in bioactive substances like chitin, chitosan, gelatins, and alginate, which can replace synthetic polymers in food packaging. Although biopolymers offer biodegradability, biocompatibility, and non-toxicity, their films often lack mechanical and barrier properties compared with synthetic polymer films. This comprehensive review …

Type-2 Diabetes, Pancreatic Amylin, And Neuronal Metabolic Remodeling In Alzheimer's Disease, Noah Leibold, James R. Bain, Florin Despa

Neurology Faculty Publications

Type-2 diabetes raises the risk for Alzheimer’s disease (AD)-type dementia and the conversion from mild cognitive impairment to dementia, yet mechanisms connecting type-2 diabetes to AD remain largely unknown. Amylin, a pancreatic 𝜷-cell hormone co-secreted with insulin, participates in the central regulation of satiation, but also forms pancreatic amyloid in persons with type-2 diabetes and synergistically interacts with brain amyloid 𝜷 (A𝜷) pathology, in both sporadic and familial Alzheimer’s disease (AD). Growing evidence from studies of tumor growth, together with early observations in skeletal muscle, indicates amylin as a potential trigger of cellular metabolic reprogramming. Because the blood, cerebrospinal fluid, …

Utilization Of Probiotics To Compete With Clostridioides Difficile For Nutrient-Niches In A Variety Of In Vitro Contexts, April Elizabeth Johnson

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

Clostridium difficile is a major threat to public health and primarily affects at risk groups such as elderly, immunocompromised individuals, and individuals on antibiotics. Many decades of research have been conducted to figure out ways to exclude or reduce C. difficile colonization and toxin production. Two major proposed mechanisms for colonization resistance are production of secondary bile salts and competition for nutrients.

In Chapter 2, we found that antibiotic treatment disrupted bile salt metabolism increasing the levels of the primary bile salt cholate and decreasing the levels of deoxycholate, a secondary bile salt. However, bile salts were not required …

Impact Of Non-Thermal Plasma Generated Using Air And Nitrogen On Functional Properties Of Milk Protein Dispersions, Nikitha Modupalli, Md Mahfuzur Rahman

Food Science Faculty Publications and Presentations

This study focuses on improving the functionalities of milk protein concentrate (MPC) using a nonthermal plasma jet and plasma-activated water (PAW) with atmospheric air and nitrogen as source gases. The 5% and 10% MPC dispersions were directly treated with a plasma jet, and PAW was used to make the MPC dispersions. The dispersions were analyzed for changes in protein structure and functional properties. The treatment altered the secondary structure of MPC protein structure by increasing β-components and changing the order of random coils. The solubility of the PAW-treated 5% protein dispersions doubled due to plasma-induced modification of hydrophilic and covalent …

Native American And First-Nations Canadian And Physical Pfas Accumulations: A Literature Review, Laurel Liebeseller

University Honors Theses

Native communities' exposure to anthropogenic Per- and Polyfluoroalkyl Substances (PFAS: "Forever Chemicals") are not demographically or geographically evenly distributed. Those who live near or on contaminated land or water are the most likely to accumulate dangerous amounts of PFAS that may have serious health consequences (Tribal PFAS Working Group 2021). Areas that tend to be most contaminated include landfills, airports, and military bases. Often Black, Indigenous People of Color (BIPOC) and low-income communities are placed near these "sacrificial zones" due to historic and current policies that segregate and marginalize people and families to polluted lands creating great environmental injustices (Dixie). …
