Acropora cervicornis is a critically endangered Caribbean coral species facing a precipitous decline due to disease and thermal bleaching. To combat the loss of ecologically important reef-building corals, novel molecular approaches can be used to understand mechanisms of resilience and ultimately provide a means to modulate coral performance. In this study, we tested a recently developed method for gene knockdown in adult corals that utilizes short interfering RNAs (siRNAs) and the RNA interference pathway. The Heat Shock Protein 16.2 (HSP16.2) gene in fragments of adult A. cervicornis was targeted for knockdown using a single siRNA construct. RT-qPCR analysis of HSP16.2 …

Fast Hyperspectral And Super-Resolved Mapping Of Lipid Membrane Polarity With Single-Molecule Sensitivity, Elric Dion Pott, Meek Yang, James Ethan Batey, Jole Embree, Bin Dong

Chemistry & Biochemistry Faculty Publications and Presentations

Cell membranes display nanoscale heterogeneity in lipid composition and organization that regulates vital biological processes yet remain challenging to resolve with conventional imaging. We introduce spectral phasor single-molecule localization microscopy (SP-SMLM), a hyperspectral and super-resolution method that combines wavefront-like optical filtering with single-molecule imaging for simultaneous spatial and spectral analysis. A lab-built three-channel imager with sine/cosine filters encodes emission spectra of single molecules into the phasor space, enabling high-throughput, high-SNR mapping of membrane polarity at sub-50 nm spatial and 15 s temporal resolutions. Through simulation, we validate that the phasor angle correlates with the spectral mean for single dye molecules. …

Influence Of Sediment Composition On Seagrass Growth, Hattie Lechner, Joshua Ahrens

Ocean Engineering and Marine Sciences Student Publications

Seagrass Beds are a vital component of the Indian River Lagoon (IRL). They support biodiversity and improve water quality, yet they have experienced significant declines in recent years. Multiple restoration efforts have attempted to replant seagrass in the lagoon and have experienced varying levels of success. Sediment characteristics such as grain size, pH, and nutrient/sulfide concentrations can influence seagrass health and growth, but the relative importance is unclear. This study investigated the relationship between sediment characteristics and the performance of the seagrass Halodule wrightii across multiple different types of sediments found within the IRL in order to identify ideal sediments/locations …

Finding Jaws: Dna Barcoding Shark Cartilage To Identify Species, Kenna Peters

Ocean Engineering and Marine Sciences Student Publications

Elasmobranchs (sharks and rays) are vital keystone predators that help regulate the health of marine ecosystems, and some of the largest and most wide-ranging fishes in the ocean1. Elasmobranch identification is difficult due to morphological similarities between species, and the high risk of encountering cryptics. These are evolutionarily distinct, but physically identical to more common taxa, and can only be identified using genetics. Misidentification is a major obstacle to shark science, especially considering new data showing that >70% of all elasmobranchs have been lost in the past 50 years, and many sharks are now shifting ranges in response to global …

Photochemical Activation Of Cyanine-Based Nanogels For Controlled Drug Delivery, Presley Clary

Chemistry and Chemical Engineering Student Publications

Cyanines are highly conjugated molecules with useful properties, such as ease of aggregation and fluorescence. In this project, they were incorporated into an acrylamide-based nanogel made through organic synthesis to exploit these properties for controlled drug delivery. Exposing the nanogel to nearinfrared (NIR) light causes it to react with reactive oxygen species (ROS), forming an unstable intermediate. The intermediate splits into two fragments, releasing the nanogel's cargo.1 The cargo, temozolomide, is an alkylating agent which can be used to disrupt the DNA of cancer cells.

Bromelain proteins are a group of digestive protease enzymes that act as a chemical defense to prevent grazing. Bromelain is often taken as a dietary supplement in an attempt to support digestion, and it is used as a meat tenderizer in the restaurant industry. Extracting Bromelain from pineapple, especially the skin, leaves, and stem of the plant, can create a value-added product from what is widely considered to be agricultural waste. In this research, we examined the difference in Bromelain concentrations between the flesh of the pineapple and the skin, leaves, and stem of the pineapple, and the efficacy of …

Theory And Simulations Of Delayed Stochastic And Deterministic Models Of Prion Diseases, Gangadhara Boregowda, Omar Sharif, Daniel Gutierrez Iii, Allegra Simmons, Laurent Pujo-Menjouet, Tamer Oraby, Michael R. Lindstrom

School of Mathematical & Statistical Sciences Faculty Publications

Neurodegenerative diseases (NDs), such as Alzheimer’s, Parkinson’s, and prion diseases, are characterized by the dynamical spread of toxic proteins through the brain. In prion diseases, cellular prion protein (PrPC), produced by neurons, misfolds into a toxic form, known as scrapie prion protein (PrPSc). PrPSc induces neuronal stress which ultimately leads to cell death. In this paper, we develop mathematical models for the progression of prion diseases, incorporating a cellular defense mechanism that introduces a delay term affecting protein translation and a volatility term accounting for unaccounted biological factors influencing the system. We also extend the model to capture the spatial …
