Utilizing The Zebrafish Model To Determine Anti-Epileptic Properties Of Mistletoe And Cannabis, Collin Dietrich
Honors Theses
Epilepsy affects around 50 million people in the world, therefore improving treatment efficacy and safety for epileptics is imperative. In this study we sought to screen the effectiveness and safety of cannabis constituents (delta-9-tetrahydrocannabinol and cannabidiol) and Tapinanthus globiferus extracts in treating epilepsy. We used a zebrafish model wherein seizures were induced by treatment with pentylenetetrazol. Our results showed that Tapinanthus globiferus dose-dependently reduced seizure activity, and no toxicities were seen at the concentrations used. In contrast delta-9-tetrahydrocannabinol and cannabidiol did not significantly reduce seizure activity and some toxicities were seen at the higher concentrations tested. We conclude that extracts …

Biochemical Variation In Caribbean Sponges Of The Genus Aplysina, Sarah L. Criddle
Honors Theses
Sponges are among the simplest multicellular organisms, consisting of groupings of cells with similar functions rather than true tissues. Nonetheless, sponges are ecologically significant in many marine environments, including coral reefs. They are sedentary organisms that feed by filtration from the water column, which contributes to the numerous roles they play on coral reefs, including upkeep of the reef, production of usable energy, and recycling of nutrients. Like all multicellular organisms, sponges are made up of biologically significant macromolecules. These macromolecules provide the energy for the sponge, and their relative concentrations determine how sponges can store and access the energy …

Synthesis And Biological Evaluation Of Cannabinoid Receptor Ligands, Mariah Leigh Cole
Honors Theses
The cannabinoid receptors, members of the G-protein coupled receptor (GPCR) superfamily, have been implicated in numerous human physiological functions and diseases. These receptors, cannabinoid type 1 (CB1) and cannabinoid type 2 (CB2), are most concentrated in the central nervous system and immune cells, respectively, and have each become a target of therapeutic interest. Dual CB1/CB2 agonists such as delta-9-tetrahydrocannbinol (THC) have demonstrated efficacy in the treatment of nausea, pain, and glaucoma, but suffer from psychotropic effects mediated by CB1, motivating the search for CB2 selective therapeutic agents. Selective modulation of the CB2 receptor has therapeutic potential in human health disorders …

Dissertations and Theses
Micro- and nano-motors have attracted numerous attentions from various scientific areas due to their potential applications. Most studies on self-propelled colloidal engines have exploited catalytic decomposition of hydrogen peroxide to drive the motor. Since the hydrogen peroxide is caustic, it is not suitable to use in biological applications, encouraging people to develop “greener” fuels. The aim of this research is to study a new transduction mechanism for self-propulsion not tied to hydrogen peroxide, and which can in particular be used with biological molecules as fuels. In this study, we focus on making particles with enzymatic activity which can effectively decompose …
