The Effect Of Different Heavy Metal Acetate Solutions On The Inhibition Of Catalase Enzyme, Athreya Murali, Sonali Patel
Journal of the South Carolina Academy of Science
The purpose of this experiment was to determine the effect of different aqueous solutions of ionic compounds on the rate of reaction of the enzyme catalase. The hypothesis states that zinc and cadmium acetate solutions will significantly inhibit catalase and its ability to produce oxygen. In the experiment, there were five trials performed with the lead acetate, zinc acetate, acetic acid, cadmium acetate, and distilled water (the last being the control group). In order to calculate the results, the ANOVA single factor test was used, comparing each solution to water. From results of the ANOVA test, it was found that …
The Effects Of Tension, Curvature, And Lipid Diffusion On The Enrichment Of Ras Proteins In Model Membranes, Nina Daneshvar
The Effects Of Tension, Curvature, And Lipid Diffusion On The Enrichment Of Ras Proteins In Model Membranes, Nina Daneshvar
Journal of the South Carolina Academy of Science
An intriguing aspect of the cell membrane that provokes study is lipid-anchor enrichment of lipidated proteins on the cell membrane. Specifically, recent in vitro studies involving the enrichment of Ras proteins were done to see how enrichment was affected by changes in membrane curvature. These studies demonstrated the Ras protein’s inclination to the expanded, or outer, leaflet of highly curved membranes. Other research done in vivo, however, provoked further inquiry into Ras protein behavior, since when highly curved protrusions were created in living cells, Ras proteins showed affinity for the inner leaflet. This inspired research to determine the exact mechanism …
The Effect Of Temperature On Zinc Leaching From Rubber Tire Mulch, Elizabeth Dillon
The Effect Of Temperature On Zinc Leaching From Rubber Tire Mulch, Elizabeth Dillon
Journal of the South Carolina Academy of Science
Scrap tires are being recycled into many products in order to bypass slow degradation in landfills. Recycled rubber tire mulch contains zinc oxide used in tire formation that can be released through the creation of leachates. This study examines the relationship between temperature environment and leachate zinc concentration. After observing rubber mulch surface temperatures in conjunction with other factors, it was hypothesized that higher temperatures would lead to increased zinc release by rubber mulch and higher leachate zinc concentrations. Leachates were created by mixing 10 grams of mulch and 200 mL distilled water and placing in 5ºC, 29ºC, and 71ºC …

Progress Toward Phidianidine Analogues Containing A 1,2,3-Triazole Ring, David Laws Iii, Dillon King, Bryan H. Wakefield
Journal of the South Carolina Academy of Science
Phidianidines are a class of compound that has been extracted from the sea mollusk Phidianis militaris. These compounds have been shown to exhibit a variety of useful properties such as antihistamine effects, anti-cancer activity, agonism of the µ-opioid receptor and neuroprotection. The biological activities are thought to be caused by the 1,2,4- oxadiazole ring found within the molecule. The goal of this project is to synthesize analogues of phidianidine that contain a 1,2,3-triazole instead of the 1,2,4 oxadiazole ring using a method that will allow for other regions of the molecule to be changed. This will help to elucidate …

The Effects Of Sports Related Head Impact On Balance And Neurocognitive Functions, Shaquanda D. Ross-Simmons, Michelle L. Vieyra, Abhishek Jain, Keri Weed
Journal of the South Carolina Academy of Science
The goal of this study was to investigate the effects of sports-related head injury on balance, attention, and memory. Reliable differences have been found using measures that directly tap into brain functioning, such as the auditory oddball task combined with EEG recording. We hypothesized that athletes reporting a diagnosed concussion or participation in high-risk sports would have compromised balance and neurocognitive functioning compared to athletes in low risk sports. Forty-five undergraduate participants were identified as either concussed, non-concussed in high-risk sports, or non-concussed in low-risk sports using a survey of athletic history, head trauma and demographics. The Biopac MP36 system, …

The Synthesis And Characterization Of Corannulene-Based Metal-Organic Frameworks, Marygrace H. Rainsford
Journal of the South Carolina Academy of Science
Due to the great demands within the energy community, the need to develop materials that can significantly alter the vitality of different substances is one of the top priorities of researchers. In recent years, metal-organic frameworks (MOFs) have been synthesized to potentially be used as these advances. The objective of this project is to specifically alter the synthetic route of corannulene-based MOFs to create a new anode for a Li-ion battery used in hybrid cars. Due to the crystalline materials porosity and high surface area, the rate performance of this battery can effectively be improved. To do this, a three …
Using Polymerization, Glass Structure, And Quasicrystalline Theory To Produce High Level Radioactive Borosilicate Glass Remotely: A 20+ Year Legacy, Carol M. Jantzen
Using Polymerization, Glass Structure, And Quasicrystalline Theory To Produce High Level Radioactive Borosilicate Glass Remotely: A 20+ Year Legacy, Carol M. Jantzen
Journal of the South Carolina Academy of Science
Vitrification is currently the most widely used technology for the treatment of high level radioactive wastes (HLW) throughout the world. Most of the nations that have generated HLW are immobilizing in borosilicate glass. One of the primary reasons that glass has become the most widely used immobilization media is the relative simplicity of the vitrification process, e.g. melt a highly variable waste with some glass forming additives such as SiO2 and B2O3 in the form of a premelted frit and pour the molten mixture into a stainless steel canister. Seal the canister before moisture can enter …

Differential Response Of Coral Symbiotic Dinoflagellates To Bacterial Toxins That Produce Bleaching In Stony Corals, Diego L. Gil-Agudelo, Yael Ban-Haim, Eugene Rosenberg, Garriet W. Smith
Journal of the South Carolina Academy of Science
Bleaching of corals and other organisms with symbiotic zooxanthellae is a worldwide phenomenon with increasing importance due to global warming scenarios. Bleaching has been historically related to changes in the environment, especially water temperature increase, that stress corals and provoke the release of zooxanthellae. The discovery of Vibrio shilonii, a bacterium causing bleaching under thermal stress in corals of the Mediterranean Sea has changed our thinking about the cause (or explanation) for bleaching of corals worldwide. During this study, we evaluated the effect of a proline rich toxin, extracted from Vibrio shilonii, on zooxanthellae obtained from: Oculina patagonica from the …

Journal of the South Carolina Academy of Science
Several pyrazole-benzenesulfonamides were subjected to biological evaluation involving tumor formation on potato discs caused by Agrobacterium tumefaciens. This assay led to some excellent and promising initial results with three of the pyrazole compounds showing increased tumor inhibition when compared to a recognized standard, camptothecin. The select pyrazole-benzenesulfonamides were prepared by condensation-cyclization of several dilithiated C(α),N-phenylhydrazones with lithiated methyl 2-aminosulfonyl-benzoate.

Journal of the South Carolina Academy of Science
Infectious diseases caused by drug-resistant microorganisms have become a major contributor for human morbidity and mortality. To overcome such threats, we have developed various antimicrobial agents using natural product derivatives and metallopolymers. Abundant biomass such as resin acids can be utilized to prepare cationic polymers for inhibiting a variety of bacteria. These polymers have been used in solution as well as surfaces as antimicrobial materials with low cytotoxicity. In addition, a class of charged metallopolymers have been developed to kill superbugs such as MRSA.
