The Effect Of Nonassociative Learning On Oxidative Stress In Caenorhabditis Elegans: A Potential Application For Alzheimer’S Disease Research, Gillian Patton
The Effect Of Nonassociative Learning On Oxidative Stress In Caenorhabditis Elegans: A Potential Application For Alzheimer’S Disease Research, Gillian Patton
Journal of the South Carolina Academy of Science
Alzheimer’s disease results in learning and memory deficits due to toxic changes in the brain caused by amyloid-β plaques and oxidative stress. Oxidative stress is caused by the overproduction of free radicals, which are uncharged molecules containing an unpaired valence electron. Nonassociative learning is a type of cognitive processing that only uses one stimulus instead of two related stimuli. Cognitive processing promotes neural growth and learning, while Alzheimer’s inhibits it. The purpose of this study was to test how nonassociative learning impacts oxidative stress and thus, if it might be considered as a potential treatment option for Alzheimer’s disease. It …

The Effect Of Flavonoid Galangin On The Cell Viability And Toxicity Of Mcf-7 Human Breast Cancer Cells Exposed To Polycyclic Aromatic Hydrocarbons (Pahs), Abhimanyu Sailesh
Journal of the South Carolina Academy of Science
Polycyclic aromatic hydrocarbons (PAHs) are chemical compounds ubiquitous in the environment; many of which are known human and animal carcinogen. The purpose of this study was to investigate MCF-7 epithelial breast cancer cells’ viability and toxicity following a short-term in vitro exposure to a cocktail of PAHs and benzo[a]pyrene (B[a]P) separately in the presence and absence of varying concentrations of flavonoid galangin. It was predicted that presence of galangin will completely or partially block the damaging effects of PAHs. It was hypothesized that exposing the cells to 7 µM cocktail of PAHs or 10 µM B[a]P in the presence of …
Epha4b Expression In The Craniofacial Development Of African Cichlid Fishes, Chelse Vanatter
Epha4b Expression In The Craniofacial Development Of African Cichlid Fishes, Chelse Vanatter
Journal of the South Carolina Academy of Science
Epha4b gene expression may contribute to variances in facial formation including functional differences such as nose shape and clinical conditions such as cleft palate. During craniofacial development, neural crest cells migrate to the pharyngeal arches then differentiate to form bone, muscle, and cartilage cells. The Eph/ephrin signaling pathway guides the streams of migrating neural crest cells into the pharyngeal arches; epha4b, a gene encoding an Eph receptor, contributes to this signaling pathway. To determine how epha4b expression differs between species at different developmental stages, in situ hybridization, a process that stains areas of gene expression, was performed. African cichlid fish …
The Effect Of Acetaminophen (Analgesic) And Diphenhydramine (Antihistamine) On Nociception Response Of Caenorhabditis Elegans, Heart Rate Of Eisenia Fetida, And Mortality Of Both E. Fetida And C. Elegans, Vamsi Gorrepati
Journal of the South Carolina Academy of Science
Pharmaceutical pollution continues to increase each year but its adverse effects on the environment are still largely unknown. Pharmaceuticals can enter the terrestrial ecosystem when animal manure and sewage sludge are applied to land as a fertilizer or when irrigated with contaminated water. To understand the extent to which common drugs impact the ecosystem, two commonly polluting pharmaceuticals, acetaminophen and diphenhydramine, which have been found in many cities such as Chicago, Dallas, and most notably The Great Lakes, were studied. Various concentrations were tested on E. fetida and C. elegans. Indicators such as heart rate were observed for E. …
The Effects Of Oxidative Stress On Inducing Senescence In Human Fibroblasts, Shivani Chowdhary
The Effects Of Oxidative Stress On Inducing Senescence In Human Fibroblasts, Shivani Chowdhary
Journal of the South Carolina Academy of Science
Oxidative stress, specifically from hydrogen peroxide exposure, was performed to determine if it induced senescence in cell lines such as Hela cells and primary human fibroblasts. The purpose of this experiment was to find the optimal stage, concentration, and time of exposure to induce the greatest number of senescent cells. After dividing cultures of both the Hela and human fibroblasts cells in order to reduce confluency, the cells were placed in a six well plate and exposed to hydrogen peroxide for two hours at various concentrations. The plates were checked at twenty-four-hour intervals, and then fixed with senescence associated beta-galactosidase …

Identification Of Coliphages In The Aviary At Brookgreen Gardens And The Factors That Might Influence Coliphage Population Dynamics In This Cypress Swamp Environment, Olivia Shirley, Lisa Pieterse, Paul E. Richardson
Identification Of Coliphages In The Aviary At Brookgreen Gardens And The Factors That Might Influence Coliphage Population Dynamics In This Cypress Swamp Environment, Olivia Shirley, Lisa Pieterse, Paul E. Richardson
Journal of the South Carolina Academy of Science
It has been understood that the presence of coliphages (bacteriophages specific for E. coli) in water is an indirect measurement of fecal contamination. Bacteriophages have been suggested to hold an important role in regulating the bacterial population. This pilot study analyzes the relationship between the presence of coliphages in the water in the aviary at Brookgreen Gardens and how environmental factors such as temperature, pH, and turbidity affect the presence of these viruses over the time period of three months (June 2017 through August 2017). Coliphages found in volary water sources were speculated to be deposited directly by birds that …
An Investigation Of The Order Of Applying An Emollient With A Topical Steroid In The Treatment Of Atopic Dermatitis, Andrea Conner, Ashlee Tietje
An Investigation Of The Order Of Applying An Emollient With A Topical Steroid In The Treatment Of Atopic Dermatitis, Andrea Conner, Ashlee Tietje
Journal of the South Carolina Academy of Science
In 2007, the prevalence of Atopic Dermatitis had increased two to three-fold within the last three decades and affected 15-20% of young children (Buys, 2007). Current treatment includes the use of both steroid and emollient creams. Current suggestions for the order of application are contradictory. This study aims to examine the role of the order of application of treatments for Atopic Dermatitis (AD). Hairless mice (SKH-1) were induced to a mild AD flare-up using 2,4-dinitrochlorobenzene (DNCB) and treated with either 1% hydrocortisone (Maximum Strength Cortizone 10 cream) alone, 1% hydrocortisone followed by Cetaphil (emollient), or Cetaphil followed by 1% hydrocortisone. …

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 …
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 …

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, …
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 …

Antitumor Activity Of Selected Derivatives Of Pyrazole- Benzenesulfonamides From Dilithiated C(Α), N-Phenylhydrazones And Lithiated Methyl 2-(Aminosulfonyl)Benzoate, N. Dwight Camper [Deceased], James M. Gum, Darby E. Lyles, William T. Pennington, Charles F. Beam, Clyde R. Metz
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.

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.
The Slow Food Movement: A 'Big Tent' Ideology, Mark N. Wexler, Judy Oberlander, Arjun Shankar
The Slow Food Movement: A 'Big Tent' Ideology, Mark N. Wexler, Judy Oberlander, Arjun Shankar
Journal of Ideology
The Slow Food Movement (SFM) has been characterized as a reminder of the centrality of the kitchen in the “good old days”. It has also been referred to as a poor use of science posing as a rallying point for the beleaguered middle class trying to reclaim psychological territory lost to the fast-paced commercialization of what was once private or leisure time. This paper argues that both these criticisms contain more than a kernel of truth. However, each misses the mark when it comes to explaining the relative successes of SFM. In this paper, we explore SFM’s basic ideological premises. …

Xenoestrogens From Household Plastics Bind Estrogen Receptors And Affect Cell Proliferation, Susan G. Hurley, Brett R. Lackey, Patricia L. Tate, Sandra L. Gray
Journal of the South Carolina Academy of Science
Xenoestrogens are “foreign” chemicals or compounds that interact with estrogen receptors as either agonists or antagonists to interfere with endocrine system function. Xenoestrogens include phytoestrogens, pesticides, industrial by- products and synthetic estrogens. In this study, consumer plasticware, including baby bottles and food storage containers, were found to release xenoestrogenic compounds that bound to ERα and ERβ and affected cell proliferation.

Assessing The Synergistic Effect Of Caffeine And Sugar On Cognitive Performance In Undergraduate Students, Sandra P. Urquiza, Michelle Vieyra
Assessing The Synergistic Effect Of Caffeine And Sugar On Cognitive Performance In Undergraduate Students, Sandra P. Urquiza, Michelle Vieyra
Journal of the South Carolina Academy of Science
Working independently, both caffeine and sugar provide benefits to attention and memory. However, there is sparse literature on the synergistic effects on improved cognitive performance between caffeine and sugar when taken together. This study explored the dynamics between caffeine and sugar when consumed under ordinary conditions – as a cup of coffee. Twenty-four undergraduate students (15 women and 9 men) were asked to complete a baseline cognitive test, and one of the three variables was given at random in the form of a cup of coffee: decaffeinated with sugar, caffeinated with no sugar, and caffeinated with sugar. The remaining two …

Essential Oils From Apple Mint (Mentha Suaveolens) And Passionflower Fruit (Passiflora Incarnata): Studies On Cognition, Coordination, And Chemical Components., Evelyn F. Patrick *, Jessie Bowers *, Shannon Read *, Brett R. Lackey, Christine Murphy, Sandra L. Gray
Journal of the South Carolina Academy of Science
Plant essential oils (EO) are used as perfumes, lotions and air fresheners because of their pleasant aromas, but EO also have the ability to elicit changes in mood and behavior. These activities are influenced by the mode of administration and by multiple signaling pathways. The EO aromas from organically grown apple mint (Mentha suaveolens) and passionflower fruit (Passiflora incarnata) were assessed for their effects on cognition and coordination. Participants completed two tasks designed to test working memory and bimanual task efficiency in rooms infused with apple mint, passionflower fruit or control EO. Bimanual coordination was assessed using the Intercept2 program …
Understanding Phylogenies: Constructing And Interpreting Phylogenetic Trees, Joseph L. Staton
Understanding Phylogenies: Constructing And Interpreting Phylogenetic Trees, Joseph L. Staton
Journal of the South Carolina Academy of Science
Interpretation of phylogenetic trees is fundamental in understanding the relationships between organisms, their traits or characteristics, their ecology and even their genomic and developmental biology. As trees appear more often in basic texts, many students, and even their teachers, clearly understand little of how they are constructed and even less about what can be inferred from them about the history of the representatives analyzed. Not only are these trees a source of confusion on what they do tell us, often non-specialists infer things wrongly or, worse, others misuse them in an attempt to negate the validity of evolutionary theory. In …
