The Effect Of Concentration Of Co2 On The Average Rate Of Photosynthesis In Spinach Leaf Disks, Amelia Robinson-Brown
The Effect Of Concentration Of Co2 On The Average Rate Of Photosynthesis In Spinach Leaf Disks, Amelia Robinson-Brown
Journal of the South Carolina Academy of Science
The purpose of this experiment was to determine the effect of carbon dioxide concentration on the rate of photosynthesis in spinach leaves. Small circular disks were cut out of the spinach leaves using a standard hole puncher. Then solutions of differing concentrations of carbon dioxide, 0.2%, 0.4%, 0.6%, 0.8%, and 1.0%, were all prepared, and each solution was spread equally among five cups. There was also a control solution that contained only water. Any gases within the leaves were then sucked with a syringe, using a specific technique to create a vacuum. For each solution of differing carbon dioxide concentration, …
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 …
Novel Mosquito Control: A Natural Approach To Reducing And Repelling Mosquito Populations, Vinita Cheepurupalli
Novel Mosquito Control: A Natural Approach To Reducing And Repelling Mosquito Populations, Vinita Cheepurupalli
Journal of the South Carolina Academy of Science
Mosquitoes are a major concern to human health because they serve as vectors to pass agents that cause diseases, such as malaria, the Zika virus, and the West Nile virus, which can have a multitude of harmful side effects, such as seizures, conjunctivitis, and death. The overuse of commercial mosquitocidal agents have caused mosquitoes to develop resistance and cause harm to humans and the environment. To prevent this, natural extracts could be used. The purpose of this experiment was to test various plant extracts for their effectiveness in acting as larvicides, adulticides, and repellents against Culex quinquefasciatus mosquitoes. It was …

The Effects Of Sports Related Head Impact On Balance And Neurocognitive Functions, Shaquanda D. Ross-Simmons, Michelle L. Vieyra, Abhishek Jain, Keri Weed
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, …

Investigating The Toxicity And Accumulation Of 2,4-Dichlorophenoxyacetic Acid (2,4-D) And Glyphosate In Eisenia Fetida, Caitlin Lazurick, Nicole Lidzbarski, Rachel Owings, Jeff Brotherton, Edna Steele
Journal of the South Carolina Academy of Science
Glyphosate, the main ingredient in Roundup®, is the most widely used herbicide in the world. It is also used in combination with another effective herbicide, 2,4-D, in the formulation called Enlist Duo®. The EPA approved the use of Enlist Duo® on certain crops including those genetically modified to be resistant to both herbicides. The predicted significant increase in the use of these herbicides raised concerns from the general public because both compounds have been classified as possibly or probably carcinogenic. Since herbicides are applied directly to vegetation, the safety of organisms that come in contact …
Investigation Of Moringa Oleifera Leaf Extract And Its Cancer-Selective Antiproliferative Properties, Reagen H. Welch, Ashlee H. Tietje
Investigation Of Moringa Oleifera Leaf Extract And Its Cancer-Selective Antiproliferative Properties, Reagen H. Welch, Ashlee H. Tietje
Journal of the South Carolina Academy of Science
Moringa oleifera is a tree native to a number of Asian, African, and Central American countries and has been used in traditional medicine for an assortment of medicinal uses for centuries. Due to bioactive compounds within Moringa leaves, it is believed that Moringa leaf extract may possess cancer-selective antiproliferative properties. Previous research has been conducted in regards to this topic, but poor experimental design due to lack of necessary controls limits the legitimacy of anticancer claims. While previous research has shown that Moringa leaf extract has the potential to kill cancer cells, the research fails to demonstrate the effects of …
Optimizing Sperm Collection Procedures In Zebrafish, Madelyn B. Wasden, Rachel L. Roberts, April Delaurier
Optimizing Sperm Collection Procedures In Zebrafish, Madelyn B. Wasden, Rachel L. Roberts, April Delaurier
Journal of the South Carolina Academy of Science
Zebrafish are a highly-valued model organism used for developmental biology research. Zebrafish can be used for genetic manipulation and hence, many mutant and transgenic lines exist. It is impractical to maintain lines of adult zebrafish, due to resource constraints and the need to continuously produce new generations. Therefore, a practical way to preserve zebrafish lines is to freeze sperm and retrieve lines using in vitro fertilization of fresh eggs. Most existing in vitro protocols used by research labs have a wide variety of fertilization rates (ranging from 0% to >90%). Due to this variability, lines may be at risk of …
Differences In Pragmatic Language Measures In Mothers Of Children With Autism Or Fragile X Syndrome, Michelle Huang
Differences In Pragmatic Language Measures In Mothers Of Children With Autism Or Fragile X Syndrome, Michelle Huang
Journal of the South Carolina Academy of Science
Mastery of pragmatics, which refers to the language used in different social interactions, is key to effective communication in daily life. However, studies have found that mothers of children with an autism spectrum disorder (ASD) or Fragile X Syndrome (FXS) are at an increased risk for impaired pragmatic language skills. Though many measures of pragmatic language exist for children, very few are available for these mothers. Two commonly used measures for the mothers include the Pragmatic Rating Scale (PRS) and the Pragmatic Language Subscale of the Broad Autism Phenotype Questionnaire (BAPQ). This study, unlike previous ones that only look at …

Marine Tardigrades From South Carolina, Usa, Paul J. Bartels, Lilvia J. Bradbury, Diane R. Nelson
Journal of the South Carolina Academy of Science
Until now, there have been only three studies of marine tardigrades from South Carolina, USA. The Fall 2015 invertebrate zoology class from Warren Wilson College collected four sediment samples from Huntington Beach State Park: shallow beach sand, deep beach sand, shallow salt marsh sediment, and deep salt marsh sediment. No tardigrades were found in the salt marsh, but two species were found in the beach samples. Batillipes pennaki Marcus, 1946 was found in shallow and deep beach sand, and three specimens of a potentially new species of Stygarctus Schulz, 1951 were found in the deep beach sand at groundwater level. …

Emerging Antimicrobial Research Against Superbugs: Perspectives From A Polymer Laboratory, Mitra S. Ganewatta, Md Anisur Rahman, Chuanbing Tang
Emerging Antimicrobial Research Against Superbugs: Perspectives From A Polymer Laboratory, Mitra S. Ganewatta, Md Anisur Rahman, Chuanbing Tang
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.

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.

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 …
