Prevalence and Fate of Antibiotic-resistant E. coli in Municipal Wastewater Treatment Plants across Oregon

Creator:: Khorshidi Zadeh, Marjan
Abstract:: Wastewater treatment plants are considered one of the main sources and reservoirs of antimicrobial resistance (AMR). This study investigated the prevalence of 8 different phenotypes of AMR, multi-drug resistant (MDR), and extended-spectrum beta-lactamases (ESBL) producing E. coli in 17 wastewater treatment plants across Oregon in winter and summer of 2019...

Effects of Whey Protein Isolate on the Human Gut Microbiota and Intestinal Function in Older Adults

Creator:: Rackerby, Bryna
Abstract:: Whey protein is a functional food comprised of numerous bioactive peptides and proteins, including glycomacropeptide (GMP), a hydrophilic casein peptide that separates with the whey fraction during cheesemaking. GMP has a unique amino acid composition, making it a viable nutritional therapy in disorders where certain amino acids are implicated, while...

A Promising Approach for Preventing of Diet-Induced Obesity and Fatty Liver Using Tetrahydroxanthohumol, A Synthetic Derivative of Xanthohumol

Creator:: Zhang, Yang
Abstract:: Obesity and metabolic syndrome (MetS) affect over 1.9 billion adults and 12.7 million youth in the US. If all of today’s obese American youth become obese adults, the total societal costs over their lifetime may exceed $1.1 trillion. We show that feeding rodents a high-fat diet supplemented with xanthohumol (XN)...

Species- and Temporal-Specific Coral Microbiome Fluctuations in Response to a Natural Bleaching Event

Creator:: Ewton, Erica M.
Abstract:: Corals provide a diversity of ecosystem services, are among the most biologically diverse ecosystems on Earth, and directly support ~500 million people globally; however, corals are increasingly experiencing significant threats and are undergoing severe bleaching events as the result of the warming climate. Using a two-year data set surrounding a...

Immunomodulatory Actions of Bovine Whey Protein Isolates, Glycomacropeptide, and Their Digests: Insights from Macrophage and Human Studies

Creator:: Olsen, Wyatt
Abstract:: Whey protein isolate (WPI) and glycomacropeptide (GMP) have shown potential immunomodulatory properties. In this study, we investigated their effects on pro-inflammatory cytokine secretion using both in vitro and in vivo models. In LPS-stimulated THP-1-derived macrophages, digested WPI and GMP reduced cytokine expression, while whole GMP increased secretion. The in human...

Cleaning and Sanitizing Surfaces on Produce Farms: Optimizing What, How, and When

Creator:: Ohman, Erik
Abstract:: Production of fresh produce takes place outdoors, and therefore, is exposed to many routes of contamination (e.g., soil, contaminated water, manure, etc.) by human pathogens. Although precautions are taken to reduce this risk, pathogens can be regularly introduced to produce handling facilities. To manage the risk of cross-contamination from potentially...

Metabolic effects of consumption of quercetin, ellagic acid, cherry, and apple phytochemical extracts in high-fat fed mice

Creator:: Smith, Sarah M.
Abstract:: Metabolic improvements and changes in gene expression were measured in mice fed polyphenol-rich extracts derived from apples and sweet cherries, and the common phytochemicals, quercetin and ellagic acid. Polyphenol-rich extracts were produced by solid phase extraction and column chromatography. Extracts and purified compounds were mixed into a high-fat (HF, 60%...

Survival of Listeria monocytogenes, Salmonella spp., and Staphylococcus aureus in raw yellowfin tuna during refrigerated and frozen storage

Creator:: Mou, Jing
Abstract:: The consumption of seafood in the United States has increased rapidly in recent years due to high quality protein and health benefits of seafood. Seafood can be a carrier for bacteria normally distributed in the marine environment and, in some cases, can be contaminated by human pathogens. Therefore, there is...
