The Impact of Surface Ligands and Synthesis Method on the Toxicity of Glutathione-Coated Gold Nanoparticles

Creator:: Harper, Bryan, Sinche, Federico, Wu, Rosina Ho, Gowrishankar, Meenambika, Marquart, Grant, Mackiewicz, Marilyn, and Harper, Stacey L.
Abstract:: Gold nanoparticles (AuNPs) are increasingly used in biomedical applications, hence understanding the processes that affect their biocompatibility and stability are of significant interest. In this study, we assessed the stability of peptide-capped AuNPs and used the embryonic zebrafish (Danio rerio) as a vertebrate system to investigate the impact of synthesis...

Assessing Changes in Biological Interactions of Lipid-Coated Gold and Silver Nanoparticles Based on Physicochemical Properties

Creator:: Engstrom, Arek Mackenzie
Abstract:: Nanoparticles (NPs), particles defined by their size in a single dimension (1-100 nm), are being increasingly incorporated into commercial and industrial products due to their high surface area to volume ratio that gives them unique properties, such as optical tunability and higher reactivity than their bulk counterparts. NPs can be...

Spherical Au Nanoparticle Interaction with Lipid Monolayers Probed with Sum Frequency Generation Spectroscopy

Creator:: Faase, Ryan A.
Abstract:: Nanoparticles have become more prevalent from their use in sunscreen to antimicrobial agents in socks. In light of these applications, gaining a fundamental understanding of how NPs interact with humans is crucial for their future. Specifically, how cells interact with NPs and what factors drive the modes of cellular uptake....

Characterizing whole-wheat flours produced using a commercial stone mill, laboratory mills, and household single-stream flour mills

Creator:: Ross, Andrew S. and Kongraksawech, Teepakorn
Abstract:: Background and objectives: One hard wheat and one semi-hard wheat were milled on commercial, laboratory, and household-scale flour mills with rotating elements ranging from 0.1 to 1.0 m in diameter and speeds ranging from 65 to 40,000 rpm. The aim of the study was to assess and compare the quality...

Antimutagenic potency of wheat grain and berry extracts in vitro and anticarcinogenicity of wheat grain in vivo

Creator:: Yu, Zhen
Abstract:: The antimutagenic potency of wheat grain and berry extracts was studied in vitro against several heterocyclic amines (HCAs) using the Salmonella mutagenicity assay and the anticarcinogencity of wheat grain was studied in vivo using the rat colonic aberrant crypt focus assay. Wheat bran, which binds HCAs in vitro, as well...

Distribution of recent volcanism and the morphology of seamounts and ridges in the GLIMPSE study area: implications for the lithospheric cracking hypothesis for the origin of intraplate, non-hotspot volcanic chains

Creator:: Forsyth, Donald W., Harmon, Nicholas, Scheirer, Daniel S., and Duncan, Robert A.
Abstract:: Lithospheric cracking by remotely applied stresses or thermoelastic stresses has been suggested to be the mechanism responsible for the formation of intraplate volcanic ridges in the Pacific that clearly do not form above fixed hot spots. As part of the Gravity Lineations Intraplate Melting Petrology and Seismic Expedition (GLIMPSE) project...

The Family-Home Nutrition Environment and Dietary Intake in Rural Children

Creator:: Jackson, Jennifer A., Smit, Ellen, Manore, Melinda M., John, Deborah, and Gunter, Katherine
Abstract:: Obesity and food insecurity rates are higher among rural compared to non-rural populations. Little is known, however, about how family-home environments influence childhood obesity-related behaviors, particularly in rural settings. This study examined associations between the family-home nutrition (FN) environment, food insecurity, and dietary intake (fruits, vegetables, whole grains, dairy, protein...

Overexpression of thiamin biosynthesis genes increase leaf and seed thiamin content but not resistance to Xanthomonas oryzae in rice

Creator:: Dong, Wei, Thomas, Nicholas, Ronald, Pamela C., and Goyer, Aymeric
Abstract:: Thiamin diphosphate (ThDP), also known as vitamin B1, serves as an enzymatic cofactor in glucose metabolism, the Krebs cycle, and branched-chain amino acid biosynthesis in all living organisms. Unlike plants and microorganisms, humans are not able to synthesize ThDP de novo and must obtain it from their diet. Staple crops...

Impacts of chemical modification on the toxicity of diverse nanocellulose materials to developing zebrafish

Creator:: Harper, Bryan J., Clendaniel, Alicea, Sinche, Federico, Way, Daniel, Hughes, Michael, Schardt, Jenna, Simonsen, John, Stefaniak, Aleksandr B., and Harper, Stacey L.
Abstract:: Cellulose is an abundant and renewable resource currently being investigated for utility in nanomaterial form for various promising applications ranging from medical and pharmaceutical uses to mechanical reinforcement and biofuels. The utility of nanocellulose and wide implementation ensures increasing exposure to humans and the environment as nanocellulose-based technologies advance. Here,...

Greening a Red State: Understanding the Complexities of Environmental Policy in Florida

Creator:: Dearden, Grace
Abstract:: In some legislative bodies, the use of terms like climate change and global warming is frequently seen as taboo. In the United States, voters who identify as right-leaning have reported little concern about the environment or climate change. This lack of interest is mirrored by Republican legislators who often publicly...
