Natural Antioxidants, Oybek Zufarov, Kamar Serkayev

Technical science and innovation

Antioxidants sourced from nature play a pivotal role in maintaining human health. Enzymatic antioxidants like catalase and peroxidase, alongside high-molecular-weight non-enzymatic antioxidants such as albumin and ferritin, bolster cellular defense mechanisms. Phenolic compounds, plentiful in plants, act as antioxidants and fall into different categories like phenolic acids, flavonoids, tannins, lignans, and lignin. These compounds showcase antioxidant prowess by neutralizing free radicals and binding metals, with their efficacy influenced by structural nuances and environmental factors. Moreover, flavonoids, tannins, lignans, diterpenes, and carotenoids stand out for their antioxidant prowess. Carotenoids like lycopene, present in tomatoes, display notable antioxidant potency, contributing to health …

Effects Of Uv Filter Pollutants On The Growth Of Cucurbits And Possible Implications For Humans, Leia Staples

Undergraduate Theses

One main area of concern is the use of personal care products and pharmaceuticals in society and their long-term persistence when released into the environment (Chaturvedi et al. 2021). Cucurbits, however, are well-known for taking up pollutants (Namiki et al. 2013, Christou et al. 2019, Komives et al. 2009), so it essential to ensure that these pollutants do not negatively affect growth or productivity of plants. These plants are particularly useful in society because they have many health benefits and are consumed regularly by humans. While much research has been done on how much of the pollutant travels throughout the …

Annotation Of Hypothetical Genes In Lactococcus Lactis Ssp. Il403, Jennifer A. Tangires

Student Scholar Showcase

The human gastrointestinal tract (GIT) harnesses various microbial organisms involved in almost all processes of physiological homeostasis, among these are lactic acid bacteria (LAB). These bacteria, almost all of which belong to the order Lactobacillales, are able to produce lactic acid, and play an important role in food preservation because they produce bacteriocins. Bacteriocins are antimicrobial proteins that are used to fight off related bacteria in their environment that are competing for the same resources. This study focuses on a specific LAB strain, Lactococcus lactis ssp. IL1403 where 21.9% of its predicted genes have not yet been assigned a function. …

Effect Of Assay Medium Ph On Inhibitory Ability Of Streptomyces, Trevor Swan, Miriam Gieske

Undergraduate Research Symposium 2024

Streptomyces bacteria from soil often produce antibiotics which inhibit growth of other microbes. When comparing Streptomyces’ inhibitory ability between different soils, it may be important to match the pH of the medium used in assays to the pH of the soil they came from. We assayed Streptomyces isolates collected from a long-term agricultural experiment with nitrogen-fertilized and non-fertilized treatments to determine their ability to inhibit growth of other bacteria by producing antibiotics. Average soil pH was 6.8 in fertilized soil and 7.2 in non-fertilized soil. We dotted isolates on a glucose-asparagine agar medium adjusted to different pH values and overlaid …

Foraging Culture In Iceland: Understanding The Transfer Of Plant Knowledge And Personal Views On Foraging, Ella Jane Maurer

Whittier Scholars Program

Foraging is a broad topic, practiced in different locations throughout history. This study looks into the specific practices, values, and views of foraging in Iceland. There is little previous research that has been done, working with Icelanders, and hearing their stories. Through conducting several interviews of local Icelanders with different backgrounds and a brief six-question survey via the Inaturalist application, this study looks into exactly that. By compiling stories from the interview and survey data, themes were highlighted collecting similar and contrasting statements on ways plants are foraged, opinions on Icelandic foraging culture as a whole, and ways knowledge is …

A sanitary challenge was carried out to induce suboptimal herd health while investigating the effect of amino acids supplementation on piglet responses. Weaned piglets of high sanitary status (6.33 ± 0.91 kg of BW) were distributed in a 2 × 2 factorial arrangement into two similar facilities with contrasting sanitary conditions and two different diets. Our results suggest that increased Trp, Thr, and Met dietary supplementation could support the immune systems of piglets under a sanitary challenge. In this manner, AA+ supplementation improved the performance and metabolism of piglets under mixed management and poor sanitary conditions. No major temporal microbiome …

Food Science Faculty Articles and Research

Pentadesma butyracea seed butter or fat (PBSB) is a vegetable fat extracted from the seeds of the P. butyracea plant. The butter has potential use in the food, pharmaceutical, and cosmetic industries. The study investigated traditional PBSB processing methods in Ghana and evaluated their effects on yield, physicochemical parameters, and fatty acid composition. Four traditional extraction methods were identified and evaluated, and these methods are direct wet extraction of PBSB from a fresh mixture of the seed paste and water (DEW); wet extraction of PBSB from a 12-hour fermented mixture of the seed paste and water (FWO); direct wet extraction …

Impact Of Fads Genotype On Polyunsaturated Fatty Acid Content In Human Milk Extracellular Vesicles: A Genetic Association Study, John J. Miklavcic, Natalie Paterson, Jennifer Hahn-Holbrook, Laura M. Glynn

Food Science Faculty Articles and Research

Background

Extracellular vesicles in human milk are critical in supporting newborn growth and development. Bioavailability of dietary extracellular vesicles may depend on the composition of membrane lipids. Single-nucleotide polymorphisms (SNPs) in the fatty acid desaturase gene cluster impact the content of long-chain polyunsaturated fatty acids in human milk phospholipids. This study investigated the relation between variation in FADS1 and FADS2 with the content of polyunsaturated fatty acids in extracellular vesicles from human milk.

Methods

Milk was obtained from a cohort of mothers (N = 70) at 2–4 weeks of lactation. SNPs in the FADS gene locus were determined using …
