Impacts Of Aplysina Red Band Syndrome On Secondary Metabolite Profiles And Antibacterial Activity Of The Caribbean Sponge Genus Aplysina, Mafie Claire Vickers
Impacts Of Aplysina Red Band Syndrome On Secondary Metabolite Profiles And Antibacterial Activity Of The Caribbean Sponge Genus Aplysina, Mafie Claire Vickers
Honors Theses
Coral reef ecosystems continue to decline due to abiotic and biotic factors, including disease. Although much of the existing scientific literature has focused on coral diseases, reports of sponge diseases have been increasing. This is a cause for concern, as sponges are increasingly dominant components of coral reef communities, where they are responsible for a wide range of ecological functions. A sponge disease of particular interest is Aplysina Red Band Syndrome (ARBS), which impacts the Caribbean's most abundant genus of sponges, Aplysina. Three morphotypes of branching sponges within this genus are affected, including Aplysina fulva, and the thin and thick …
The Pharmacodynamic Functions Of Low-Dose Rapamycin As A Model For Universal Influenza Protection, William Gust
The Pharmacodynamic Functions Of Low-Dose Rapamycin As A Model For Universal Influenza Protection, William Gust
Honors Theses
One of the most sought after breakthroughs in modern influenza research is the creation of a universal influenza vaccine that would protect against all strains of avian influenza. An unlikely model for this kind of protection might be found in the mTOR inhibitor rapamycin. Traditionally used to prevent organ transplant rejection, low doses of rapamycin have been found to protect mice against infection with distinct subtypes of influenza. However, it is not understood how a partial block in this pathway provides optimal heterosubtypic immunity. Interestingly, previous experiments have shown that low dose rapamycin inhibits germinal center formation to reduce antibody …
Evaluation Of Sigma Ligand Az66 Analgesic Potentiation Of Cannabinoids, Jacqueline Morris
Evaluation Of Sigma Ligand Az66 Analgesic Potentiation Of Cannabinoids, Jacqueline Morris
Honors Theses
Sigma receptors have become a popular subject for research the past few decades, but there is still much mystery behind these receptors and how they work. Sigma receptors, like cannabinoid-1 (CB1) receptors, have effects on the human body including appetite regulation, depression, and analgesia. AZ66 is a highly selective sigma receptor ligand that has antagonistic properties. Sigma receptor antagonists have been shown to potentiate the analgesic effects of opiates; however, there are no known literature reports about the interaction between the sigma receptor system and the endocannabinoid system, including CB1 receptors. The purpose of this study is to evaluate AZ66 …

The Evaluation of AZ66, A Highly Selective Sigma-1 and Sigma-2 Antagonist, for Anticonvulsive Effects in C57Bl/6 Mice (Under the direction of Lisa Wilson and Dr. Christopher McCurdy) Sigma receptors have become a popular subject for research the past few decades, but there is still much mystery behind these receptors and how they work. Researchers have found that sigma receptor antagonists can attenuate cocaine induced convulsions, however, limited research has been conducted on the effects of these antagonists on convulsions that mimic the types of seizures associated with epilepsy. Therefore, the aim of the current study was to evaluate AZ66 (20 …
Reducing The Interfacial Tension Of Magnetic Surfactants In Magnetic Fields, Rachel Anne Stanhope
Reducing The Interfacial Tension Of Magnetic Surfactants In Magnetic Fields, Rachel Anne Stanhope
Honors Theses
This thesis discusses the theory, experimental research methods, and findings of the effects that magnetic fields have on the interfacial tension of magnetic surfactant solutions. Analyzing how magnetic fields affect the properties of magnetic surfactants, including interfacial tension, is the first step to creating low energy, magnetic field induced separations to address the problem of growing energy demands for chemical and biological separations [1]. Surfactants are organic structures that contain both a hydrophilic head group and a hydrophobic tail, which aggregate toward the interface of solutions and decrease the interfacial tension until the critical micelle concentration is reached. Magnetic surfactants …
Cellulose Nanocrystal Stabilized Pickering Emulsions, Sangeet Adhikari
Cellulose Nanocrystal Stabilized Pickering Emulsions, Sangeet Adhikari
Honors Theses
The use of Pickering Emulsions in place of conventional surfactants has opened new doors in fields like pharmacy, cosmetology, and oil and gas industry. Pickering emulsions using Cellulose Nanocrystals (CNCs) are generally stable to heating in a wide range of temperatures and show great stability against salt and pH changes. The management of water resources in the United States has been a challenge. The injection of water in aging oil fields and unconventional tight-gas, shale-gas, and coal bed-fields often generate substantial amounts contaminated wastewater. This research project is expected to help future efforts in promoting oil biodegradation in emulsified mixtures. …

Hot-Fire Testing Of An Af-M315e 1-Newton Thruster, Alex Mcgee
Honors Theses
AF-M315E is a green monopropellant currently being investigated for use as a potential replacement for hydrazine in low-thrust spacecraft propulsion applications. To support devel- opment e↵orts, a series of hot-fire tests were conducted to assess the performance of AF-M315E in a 1N thruster. Preliminary design and analysis shows an increase in performance versus a comparable hydrazine system. Testing was conducted with a 1N TZM (titanium, zinc, and molybdenum alloy) thruster in late July 2016 in collaboration with the Spacecraft Propulsion Systems o ce (ER23) at Marshall Space Flight Center (MSFC). Testing focused on character- izing the transient behavior of the …
Utilizing The Zebrafish Model To Determine Anti-Epileptic Properties Of Mistletoe And Cannabis, Collin Dietrich
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 …
Development Of Standard Operating Procedure: Admicellar Polymerization Of Polystyrene Thin Film (Aibn) On Polysciences 30-50Μm Glass Beads Using Cetyltrimethyl-Ammonium Bromide Surfactant, David Langford
Honors Theses
Poly(1-phenylethene), commonly referred to as Polystyrene, is one of the world's most common polymers. Made from the monomer styrene (ethenylbenzene), this polymer is used in a wide range of products from packing peanuts to disposable cutlery. The method of polymerization used in this research project is called admicellar polymerization. This process consists of four main steps: admicelle formation, adsolubilization, polymerization, and removal of admicelle and polymer. Admicellar polymerization has a number of advantages over related methods of thin film polymerization including simplicity and low cost of components and process.

The Effects Of Ultrasonic And Photochemical Pretreatment On Heating Value And Carbon Capturing Ability Of Fast Pyrolysis-Derived Biochars, Jordan Houry, Dong Joon Kim, Cary Roy
The Effects Of Ultrasonic And Photochemical Pretreatment On Heating Value And Carbon Capturing Ability Of Fast Pyrolysis-Derived Biochars, Jordan Houry, Dong Joon Kim, Cary Roy
Honors Theses
Slow pyrolysis biochar has been shown to be receptive to ultrasonic and photochemical pretreatment that raises the heating value, surface area, and carbon content of the samples. This experiment was designed to test the feasibility of substituting fast pyrolysis derived biochar in place of slow pyrolysis biochars in order to reduce production times. Furthermore, new biomasses (switchgrass, rice husk, and rice straw) were tested for their receptiveness to pretreatment methods. It was ultimately determined that fast pyrolysis biochars that were exposed to pretreatment increased their carbon content and surface area but did not experience a heating value increase to the …

Synthesis And Biological Evaluation Of Cannabinoid Receptor Ligands, Mariah Leigh Cole
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 …
Biochemical Variation In Caribbean Sponges Of The Genus Aplysina, Sarah L. Criddle
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 …
