The Importance Of Neurolysin In The Renin-Angiotensin System Of The Mouse Brain, Eduardo Carrera, Catalina Breton, Andrea Linares
The Importance Of Neurolysin In The Renin-Angiotensin System Of The Mouse Brain, Eduardo Carrera, Catalina Breton, Andrea Linares
Undergraduate Student Symposium
The renin angiotensin system (RAS) plays a major role in cardiovascular disease. Novel metabolic pathways of the RAS offer new therapeutic targets for disease prevention. Recent studies demonstrated a novel binding site for the active hormone of the RAS: angiotensin II (Ang II). This binding site, now known to be the enzyme neurolysin, can metabolize Ang II into inactive fragments and act upon a precursor of Ang II (Ang I) to circumvent Ang II production. Radioligand binding and histological techniques were utilized to assay neurolysin and the primary receptors for Ang II (AT1, and AT2) in …
The Influence Of Alcohol And Caffeine On Cockroach Motor Function, Isaac Chayo
The Influence Of Alcohol And Caffeine On Cockroach Motor Function, Isaac Chayo
Undergraduate Student Symposium
The cockroach has proven to be an excellent model for investigating the pharmacological effects of different substances on nervous system functionality. The increased vigilance and wakefulness associated with caffeine is primarily mediated by its interactions with monoamine neurotransmitters in addition to its role as an antagonist for adenosine receptors. In the case of alcohol, it is an agonist for the inhibitory neurotransmitter GABA, which partly explains its sedative properties and disruptive effects on motor function. In this experiment, we will examine the influence of caffeine and alcohol on motor function in Blaberus Discoidalis by designing an enclosed running strip marked …
The Needs Of The Many, Nathaniel Dolan
The Needs Of The Many, Nathaniel Dolan
Undergraduate Student Symposium
The Great American Experiment began almost 250 years ago, not necessarily in pursuit of a new nation per say, but more on the grounds of courageous expedition into the unknown – a grand test-case for what a nation could be – and continues to be so courageous and experimental well into contemporary society; the experiment being whether unfettered personal autonomy can indeed exist congruently with social, cultural, and national security. Frankly, all available data suggests that such lofty ideals are ultimately not possible, and that Americans are left, nearly a quarter of a millennia after the fact, with the sobering …
The Neurophysiology Of Attractiveness, Megan Thomas
The Neurophysiology Of Attractiveness, Megan Thomas
Undergraduate Student Symposium
Evolutionary theories of human mating suggest that both men and women are interested in the most attractive members of the opposite sex. However, men may be more likely than women to be motivated to act on these interests. The goal of this study is to investigate the neurophysiological correlates of these evolved psychological mechanisms relevant to human mate attraction. Electroencephalographic (EEG) event related brain potentials (ERPs) are used as the primary index of the influence of target facial attractiveness on neurobiological processing. Salivary testosterone levels are also assessed to determine the influence of mating-relevant hormones on these processes. Measures of …

Up In The Clouds: An Analysis Of Detachment, Katherine Mcinerney
Up In The Clouds: An Analysis Of Detachment, Katherine Mcinerney
Undergraduate Student Symposium
This presentation analyzes the texts of Jonathan Swift’s Gulliver’s Travels, Evelyn Waugh’s A Handful of Dust, and Gary Shteyngart’s Absurdistan to examine a common, satirized human flaw. Despite the varied social realms in which the works exist, prevalent in all three is the theme of human detachment, exemplified by characters whose thoughts and actions reveal an emotional disconnect from their respective realities. The reactions of various characters to crucial plot events exhibit this disconnect, with displays of indifference toward poverty, war, and in the extreme, death. This essay illustrates how, through satirical content, the authors highlight behavioral factors …

What Goes On Beneath The Green Skin And Purple Pants: Physiology Of The Bruce Banner Haplotype Under Stress, Jose Luis Martinez, Giovanni Landauro, Mustari Akhi
Undergraduate Student Symposium
Aggression can occur as a goal-oriented phenomenon where the aggressor is intent on harm, during which, the aggressor experiences low levels of physiological arousal (Tulogdi, et al., 2012). Reduced physiological arousal may be associated with violent behavior, independent of other psychological risk factors. Using this view, sensation-seeking behavior, along with reduced physiological arousal, are key markers of aggression. (Wilson & Scarpa, 2011). Based on prior studies and research in this area, we are testing the idea that acute stress results in blunted biochemical and self-report measures of stress in individuals with low physiological arousal compared to individuals with typical (or …

Applications Of Abstract Algebra To Puzzle Modeling, Sharvel Bousemaan
Applications Of Abstract Algebra To Puzzle Modeling, Sharvel Bousemaan
Undergraduate Student Symposium
Abstract Algebra is an area of mathematics which focuses on the properties of algebraic structures. One such structure, called a Group, has properties which are applicable to puzzle solving. We provide the fundamental properties of permutation groups and discuss certain theorems which enable one to model a variety of puzzles. In addition, we demonstrate how the computational algebra program, GAP can be utilized in order to work with the large permutation groups that describe very complex puzzles. Our goal is to use the mathematics underlying these puzzles in order to understand how they can be solved.
A New Order In A New World: The Titan Economic Model, Linea Cutter, Nathaniel Dolan, William Kotkin, Elizabeth Mortazavi
A New Order In A New World: The Titan Economic Model, Linea Cutter, Nathaniel Dolan, William Kotkin, Elizabeth Mortazavi
Undergraduate Student Symposium
“A New Order in a New World: The Titan Economic Model” is a brief news-styled film report depicting a radical, albeit fictional, accounting of only one possible future-history for economic development of humanity. Speculating on the future-history of global economic structures raises noteworthy concerns while simultaneously setting the stage for rather radical new ideals.
A small group of NSU Honors students set about this very task of speculation on future-history in Dr. Brodman’s fall 2012 Honors course History of Economic Development. The time-frame of the film is set in December of 2012 amidst total collapse of the globalized economic …
Parasites Of Invasive Snakeheads (Channa Sp.) In Fort Lauderdale Canals, Elisa D'Abbraccio
Parasites Of Invasive Snakeheads (Channa Sp.) In Fort Lauderdale Canals, Elisa D'Abbraccio
Undergraduate Student Symposium
Snakeheads (Channa sp.) are invasive fishes native to Asia and Africa that are now ubiquitous in South Florida waterways. Their invasion of Florida waters is of concern because they are aggressive, territorial, predatory, air breathing fishes; these features have allowed them to disperse widely and adapt to a range of temperatures and environmental conditions. Their spread threatens native fishes and aquatic ecosystems throughout South Florida. Invasive species often benefit from parasite release, having fewer parasites than conspecifics in their native range and / or fewer parasites than ecologically equivalent competitors in their introduced range. To assess the possible contribution …

Gene Evolution And Conservation In Marine Sponges, Bryce Parrish
Gene Evolution And Conservation In Marine Sponges, Bryce Parrish
Undergraduate Student Symposium
The phylum Porifera makes up the foundation of the tree of life for all eukaryotes. Conducting bioinformatics studies on sponge gene sequences will be important for discovering sponge phylogenetic markers within the Phylum. This could be important for finding and tracking genes that could potentially be used as evolutionary markers within Porifera. This study will utilize previously sequenced cDNA transcripts of two sponge species, Cinachyrella alloclada and Discodermia dissoluta. We searched for gene sequences that had interesting metabolic functions and, conserved motifs within these two species. Gene sequence identities were verified with BLAST searches. Next, I performed in silico …

Renewed Presence Of The Free-Living Coral Psammocora Stellata At Devil's Crown, Galápagos Islands, Ecuador, Kayla Caldwell
Undergraduate Student Symposium
The purpose of this study was to document the renewed presence of the free-living coral Psammocora stellata in the nearly submerged volcanic cone of Devil's Crown, Floreana Island, Galápagos Islands, Ecuador, and to determine if there were changes in coral cover between two survey periods. This coral species was previously present at Devil's Crown until being extirpated in 1982-83 by impacts associated with the 1982-1983 El Niño-Southern Oscillation. It was observed there in 2007 and was surveyed in 2009 and again in 2011 using the random walk quadrat method. Colony density and live tissue cover was determined using CPCe software …
The Effect Of Secondary English Proficiency On The Reading Strategies Of International Students, Natasha Vega-Valbuena
The Effect Of Secondary English Proficiency On The Reading Strategies Of International Students, Natasha Vega-Valbuena
Undergraduate Student Symposium
Scholars have long established that all readers employ strategies to understand complex texts. The most effective readers read not just for content, but ask questions about why authors make the choices they do. These “rhetorical” readers ask not just “what?”, but why?”. Rhetorical reading strategies, as defined by Flower and Haas, are “active attempts at constructing a rhetorical context for a text as a way of making sense of it.” In other words, readers must not only interpret the words on the page based on their grasp of the English grammar and syntax, they must be able to imagine the …
The Potential Effects Of Various Concentrations Of Saccharin Compared To Sucralose, Stevia, Aspartame, Sugar, And A Typical Diet On Gene Expression In Yeast, Beric Berlioz
Undergraduate Student Symposium
Gene expression patterns present as a result of a typical yeast diet (YEPD), as well as table sugar (sucrose) and four sugar substitutes Splenda (sucralose-based), Truvia (stevia-based), Equal (aspartamebased), and Sweet N’ Low (saccharin-based) at varying concentrations (low, medium and high) were determined. The sugar and sugar substitutes were administered and examined at extremely high (340 tsp/100 pounds), typically high (34 tsp/100 pounds), and low (10 tsp/100 pounds) concentrations, according to recently published literature based on the diet of typical American teenagers. Experimental data in the 1970s demonstrated that saccharin had a link to bladder cancer in laboratory rats, making …
A B Cell Mediated Model Of Humoral Immune System Function, Abbiana Arenas
A B Cell Mediated Model Of Humoral Immune System Function, Abbiana Arenas
Undergraduate Student Symposium
Influenza claims hundreds of thousands of lives each year world wide. Unfortunately these numbers are relatively unchanged over the past few decades. Influenza vaccines work to prime the humoral immune response for subsequent challenges by the influenza virus. With this initial priming the humoral response will produce specific and highly effective antibodies for the given virus. While effective, the mechanisms of humoral memory formation and maintenance are relatively less explored than the cell mediated response. In primary infections, the innate response and CD8+ T-cells will often clear the bulk of the virus before the humoral response can produce a …

Anticancer Effects Of Pumpkin Seed Extracts On Lncap Prostate Cancer Cell Line, Rajeswari Murugan, Jackie Lynne Jornadal, Yanira Quinonez
Undergraduate Student Symposium
Clinical research has shown that Pumpkin seed (PS) is effective in treating various conditions including benign prostatic hyperplasia, inflammatory prostatitis, and prostatic secretion. However, there is insufficient scientific data available regarding the cytotoxic effects of PS on prostate cancer cells. Thus, the purpose of this study was to evaluate the cytotoxic effects of both aqueous and alcohol extracts of PS on the LNCaP prostate cancer cell line and elucidate the possible mechanisms involved in mediating these effects. During the study, LNCaP cells were treated separately with aqueous and ethanolic extracts of PS (50-200 μg/ml concentrations). After 24 hours of treatment, …
Barcoding Of The Cox-1 Region In Lagenidium Giganteum Dna, Joshua Mathews
Barcoding Of The Cox-1 Region In Lagenidium Giganteum Dna, Joshua Mathews
Undergraduate Student Symposium
The oomycete, Lagenidium giganteum, is a parasitic microbial pathogen that infects the larvae of mosquitos. Their presence can dramatically reduce the population of mosquitoes in a given area as the parasite reproduces quickly and kills many of the mosquitoes before they reach adulthood. The control of the population of mosquitoes is desirable considering the possible pathogens that the mosquitoes carry like West Nile Virus and Malaria which can infect humans and lead to death if untreated. The main purpose of this study is to barcode the Cytochrome c oxidase subunit1 (COX 1) region of the mitochondrial DNA in Lagenidium …

Undergraduate Student Symposium
Total scores of ≤14 on the Functional Movement Screen™ (FMS) have been associated with injury risk in firefighters, professional football players and female collegiate athletes. Seven movement patterns (e.g. squat, inline lunge, etc.) comprise the FMS, which are scored individually from 0 to 3, and added together for a total score. The purpose of this study was to examine injury risk in 4 groups of intercollegiate athletes, female rowers (ROW), female soccer (WSOC), male soccer (MSOC), and female volleyball players (VB) using total and individual test FMS scores. Samples of convenience were used; 27 ROW, 29 WSOC, 27 MSOC, 17 …
Exploring Mutagenic Effects Of Atmospheric Aerosol Components, Patrick Doty, Arti Patel, Divya Pandya
Exploring Mutagenic Effects Of Atmospheric Aerosol Components, Patrick Doty, Arti Patel, Divya Pandya
Undergraduate Student Symposium
Atmospheric aerosols play key roles in global climate, air quality and public health issues. In the latter case, it has been shown that aerosols may exacerbate pulmonary and cardiovascular symptoms or diseases, via pathways such as oxidative stress. However, neither the detailed aerosol composition nor how aerosols may generate certain biological responses, including human health risks, is fully understood. This study explores how several important organic aerosol components such as polyaromatic hydrocarbons (PAH) may generate mutagenic effects in Escherichia coli, using a standard mutagenicity assay. Variables such as the PAH type and temperature are tested and preliminary results will be …
Increasing Crop Yield By Stimulating Bacterial Respiration With Agricom, An Agricultural Stimulant, Noemi Bermudez, Faria Fatmi
Increasing Crop Yield By Stimulating Bacterial Respiration With Agricom, An Agricultural Stimulant, Noemi Bermudez, Faria Fatmi
Undergraduate Student Symposium
Nitrogen fixation is an essential process by which plants take in nitrogen from the atmosphere and convert it into usable inorganic nutrients. More than ninety-percent of all nitrogen fixation is carried out by nitrogen-fixing bacteria; therefore, it is hypothesized that increasing the growth of N2 fixing bacteria will ultimately increase the rate of plant development. The purpose of the first part of the experiment was to determine the appropriate concentrations of the active ingredients that constitute the proprietary, commercial growth stimulant (Agricom) that optimized bacterial respiration. A respirometer was utilized to measure bacterial respiration, which indicates levels of bacterial …
Individual Differences In Working Memory Capacity And Eyewitness Identification, Rachel Berger
Individual Differences In Working Memory Capacity And Eyewitness Identification, Rachel Berger
Undergraduate Student Symposium
A number of studies have examined the association between individual differences in working memory capacity and the production of false memories. However, the relationship between individual differences in working memory capacity and the ability to accurately identify a perpetrator out of a lineup has never been studied. The current study measures participants’ working memory capacity, sustained attention, and speed of processing in order to determine if it has an effect on people’s ability to identify a man out of a lineup. In the study, participants are placed in either a “warning” or “no warning” condition before watching a short video. …
Nh-Tautomerism In Para-Substituted Tetraphenylporphyrin Derivatives, Biana Modilevsky
Nh-Tautomerism In Para-Substituted Tetraphenylporphyrin Derivatives, Biana Modilevsky
Undergraduate Student Symposium
The NH–tautomerism of meso–substituted porphyrins has been reported to decrease with porphyrin distortion by enhancing intramolecular hydrogen bonding of the NH protons. Electron withdrawing groups should deshield the internal hydrogen’s shifting the NH chemical shift spectra further up field by affecting the ring current, and the opposite effect is expected for electron donating substituents at the meso position of the porphyrin core. The effect of several substituents in the para positions of the phenyl group of meso–substituted porphyrins would be correlated to the NH–tautomerism in phenyl– substituted porphyrins.

Queering Methodologies: Challenging Scientific Constraint In The Appreciation Of Queer And Trans Subjects, Joshua M. Ferguson
Queering Methodologies: Challenging Scientific Constraint In The Appreciation Of Queer And Trans Subjects, Joshua M. Ferguson
The Qualitative Report
Qualitative studies require a queer perspective to challenge stagnant forms of scientific discourse. This paper argues for a deconstruction of hegemonic qualitative practices in order to appreciate and listen to queer and trans subjects when employing qualitative research and methodologies. I focus on qualitative methods from an audiovisual perspective to suggest that there is scientific constraint in the way researchers still approach qualitative methodologies. I propose some foundations for thinking about queer qualitative methods that employs queer theory in relation to a self - reflexive creative perspective towards ethics, research and representation. Moreover, I critically analyze the HBO trans documentary, …
