Small extracellular vesicles (sEVs) and their RNA cargo in milk are bioavailable in humans, pigs, and mice, and their dietary depletion and supplementation elicits phenotypes. Little is known about the content and biological activity of sEVs in foods of animal origin other than milk. Here we tested the hypothesis that sEVs in chicken eggs (Gallus gallus) facilitate the transfer of RNA cargo from an avian species to humans and mice, and their dietary depletion elicits phenotypes. sEVs were purified from raw egg yolk by ultracentrifugation and authenticated by transmission electron microscopy, nano-tracking device, and immunoblots. The miRNA profile …
Assessing The Bioavailability Of Infused Lysine And Rumen-Protected Lysine Supplements Using The Area Under The Curve Technique And The Plasma Free Amino Acid Dose-Response Method, Megan Vetter
Honors Theses and Capstones
The milk production of lactating dairy cows is dependent on factors such as housing conditions, lineage, climate, and health, but the quality of their diets is generally the most influential. Maintaining a proper balance of nutrients is necessary to achieve the greatest milk production at the lowest cost. Maximum feed efficiency is not only critical for increasing the economic profits of an individual farm, but also for increasing food supply without increasing environmental demand. Supplementing cows’ diets with lysine (Lys), an essential amino acid (AA), can aid in maximizing protein synthesis. Providing this nutrient in a rumen-protected (RP) coating can …

Potential Interactions Between Diatoms And Bacteria Are Shaped By Trace Element Gradients In The Southern Ocean, Alexa R. Sterling, Laura Z. Holland, Randelle M. Bundy, Shannon M. Burns, Kristen N. Buck, P. Dreux Chappell, Bethany D. Jenkins
OES Faculty Publications
The growth of diatoms in the Southern Ocean, especially the region surrounding the West Antarctic Peninsula, is frequently constrained by low dissolved iron and other trace metal concentrations. This challenge may be overcome by mutualisms between diatoms and co-occurring associated bacteria, in which diatoms produce organic carbon as a substrate for bacterial growth, and bacteria produce siderophores, metal-binding ligands that can supply diatoms with metals upon uptake as well as other useful secondary compounds for diatom growth like vitamins. To examine the relationships between diatoms and bacteria in the plankton (diatom) size class (> 3 mu m), we sampled both …
Preliminary Evidence That Lectins In Infant Soy Formula Apparently Bind Bovine Milk Exosomes And Prevent Their Absorption In Healthy Adults, Ezra Mutai, Alice Kah Hui Ngu, Janos Zempleni
Preliminary Evidence That Lectins In Infant Soy Formula Apparently Bind Bovine Milk Exosomes And Prevent Their Absorption In Healthy Adults, Ezra Mutai, Alice Kah Hui Ngu, Janos Zempleni
Department of Nutrition and Health Sciences: Faculty Publications
Background: Milk exosomes and their microRNA (miR) cargos are bioavailable. The content of exosomes and miRs is negligible in infant formulas compared to human milk, and dietary depletion of exosomes led to changes in bacterial communities and impaired gut health in juvenile mice. Adverse effects of formula feeding may be compounded by using soy formulas due to exosome binding by abundant lectins in that matrix. The purpose of this study was to assess the bioavailability of milk exosomes and their miR cargos added to soy formula in adults, as well as the potential role of soy lectins in exosome …

The oceans teem with heterotrophic bacterioplankton that play an appreciable role in the uptake of dissolved organic carbon (DOC) derived from phytoplankton net primary production (NPP). As such, bacterioplankton carbon demand (BCD), or gross heterotrophic production, represents a major carbon pathway that influences the seasonal accumulation of DOC in the surface ocean and, subsequently, the potential vertical or horizontal export of seasonally accumulated DOC. Here, we examine the contributions of bacterioplankton and DOM to ecological and biogeochemical carbon flow pathways, including those of the microbial loop and the biological carbon pump, in the Western North Atlantic Ocean (∼39–54°N along ∼40°W) …

Investigation Of Methionine And Lysine Derivatives As A Source Of Rumen-Protected Amino Acids For Lactating Dairy Cows, Mark Avila Fagundes
Investigation Of Methionine And Lysine Derivatives As A Source Of Rumen-Protected Amino Acids For Lactating Dairy Cows, Mark Avila Fagundes
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Cows have a protein requirement for growth, maintenance, and lactation. In order to meet those protein requirements, dairy farmers can supplement or feed cattle with specific amino acids, the building blocks that make-up protein. However, in order for the amino acid product to be effective it must avoid degradation in the rumen and be delivered in the small intestine for absorption. Lysine and methionine have traditionally been recognized as the most limiting amino acids for lactating dairy cows. Therefore, nutrition companies have focused on finding ways to encapsulate or protect lysine and methionine from rumen microbes. The N-acetyl-L-methionine and N-acetyl-L-lysine …

However, pharmacokinetics of KKA has not been studied. In this study, pharmacokinetics and antiangiogenic efficacy of KKA are investigated. Methods: Pharmacokinetics of KKA was studied after intravenous and oral administration in SD rats using HPLC. Anti-angiogenic efficacy of KKA was investigated in rat aorta, human endothelial cells …
Rice Fortification By Parboiling In Limited-Water Soaking To Alleviate Mineral And Vitamin Deficiency, Annegret Jannasch
Rice Fortification By Parboiling In Limited-Water Soaking To Alleviate Mineral And Vitamin Deficiency, Annegret Jannasch
Graduate Theses and Dissertations
Fortification of rice by parboiling is considered a potential alternative to currently available fortification technologies to produce rice with higher mineral and vitamin content significantly contributing to nutrient intake in populations with high prevalence of micronutrient deficiencies. Higher nutrient retention rates and improved sensory characteristics are advantages of fortified parboiled rice compared to fortified rice obtained by currently used fortification technologies including dusting, coating, and extrusion. However, conventional parboiling processes employ excess water that presents an environmental hazard if discarded without treatment. Thus, the objective of this study was to evaluate a limited-water soaking method for the fortification of rice …

Micrornas In Bovine Milk Exosomes Are Bioavailable In Humans But Do Not Elicit A Robust Pro-Inflammatory Cytokine Response, Ezra Mutai, Amanda E. Ramer-Tait, Janos Zempleni
Department of Nutrition and Health Sciences: Faculty Publications
Background: Bovine milk exosomes are studied for their roles as bioactive food compounds and as vehicles for drug delivery. Both lines of investigation converge on immune function, e.g., immune regulation by absorption of microRNAs encapsulated in milk exosomes across species boundaries, and the possibility of exosomes and their cargos triggering an immune response if used in drug delivery. This study assessed the bioavailability of immune-related microRNAs from bovine milk and changes in plasma cytokine concentrations after milk consumption in humans, and the secretion of cytokines by human peripheral blood mononuclear cells (PBMCs) cultured with milk exosomes transfected with immune-relevant microRNAs. …

In Vitro Bioaccessibility Of Novel Low-Crystallinity Phytosterol Nanoparticles In Non-Fat And Regular-Fat Foods, Ali Ubeyitogullari, Ozan Ciftci
Department of Food Science and Technology: Faculty Publications
Crystalline structure of phytosterols leads to poor bioavailability and makes their incorporation into foods challenging. Bioaccessibility of first-of-their-kind low-crystallinity phytosterol nanoparticles impregnated in nanoporous starch aerogels (PS-NSA) was evaluated in non-, low-, and regular-fat solid and aqueous food formulations, namely, granola bars and puddings for the first time. Bioaccessibility of the phytosterol nanoparticles was significantly higher than that of crude phytosterols in all food formulations (p < .05); it was 88.2 and 91.8% for low- or regular-fat granola bars, respectively, whereas bioaccessibility of crude phytosterols was ca. 30% in those formulations. However, decreasing the lipid content to zero resulted in lower phytosterols' bioaccessibilities from both PS-NSA (53%) and crude phytosterols (ca. 16%) in non-fat granola bars. Bioaccessibility of crude phytosterols (2%) was significantly enhanced with PS-NSA (19%) in the pudding formulation. PS-NSA allows preparation of low- and non-fat foods enriched with phytosterols while enhancing the health benefits of phytosterols with smaller doses.

Increasing Cis-Lycopene Content Of The Oleoresin From Tomato Processing Byproducts Using Supercritical Carbon Dioxide And Assessment Of Its Bioaccessibility, Lisbeth Vallecilla Yepez
Department of Food Science and Technology: Dissertations, Theses, and Student Research
In recent years, health- and wellness-promoting foods have been one of the major focus of consumers; therefore, the food industry is increasing its efforts in developing these food products. Tomatoes, tomato-food products and their byproducts have gained special attention in virtue of the carotenoids-rich source that they represent, especially lycopene (~90%). The role of lycopene in human diet has been highlighted as a result of its direct relationship with the decrease of chronic diseases. Nevertheless, lycopene is water-insoluble making its extraction simple with organic-toxic solvents; in addition, lycopene degrades easily with light, time, and storage. Lycopene exist in nature mostly …

The Summer Undergraduate Research Fellowship (SURF) Symposium
There are many different active pharmaceutical ingredients (APIs) that have been discovered in research labs all around the world that can be used to treat and cure patients with a variety of different ailments. The challenge with these APIs in treatments is that they are not soluble in water, thus they low absorption into the blood stream (bio-availability). The key to making these APIs more bio-available is to understand how they grow as crystals and drop out of the aqueous solutions. One of the ways these APIs were made more bio-available is to render them amorphous and suspend them in …

Brain Bioavailability Of Polyphenols: Implications For Delivery Of Brain Health Benefits, Tzu-Ying Chen
Open Access Dissertations
Consumption of fruits and vegetables has been associated with neuroprotection and cognitive benefits throughout the life span. These associations have sparked interest in plant-derived polyphenols as biologically active agents with potential for targeting brain benefits. However, little is known regarding the ability of the polyphenols or their metabolites from polyphenol-rich products to cross the blood-brain-barrier, and be available for biological action. Furthermore, additional insight is needed on factors affecting the absorption and brain distribution of polyphenol metabolites in vivo. To fill gap in current knowledge, this thesis will focus on the effects of diabetogenic diet and diabetic state which have …

ABSTRACT: The export of old leaves and stems (wrack) from seagrass meadows provides a mechanism for trophic connectivity among coastal ecosystems. As little of this wrack is consumed by mesograzers, leached dissolved organic carbon (DOC) may determine the importance of wrack as a trophic subsidy. However, few studies have examined the effect of seagrass type or age on the release of DOC or its bioavailability. We examined the amount and composition of DOC released from different wrack: Posidonia sinuosa, Amphibolis antarctica and the alga Laurencia sp. We then examined the effect of age on DOC leaching from P. sinuosa wrack. …
