Nucleotide Excision Repair: A New Component In The Study Of Breast Cancer, Monica Azer Apr 2013

Nucleotide Excision Repair: A New Component In The Study Of Breast Cancer, Monica Azer

Undergraduate Student Symposium

Breast cancer is a prevalent cancer that occurs in many women and men today. There are many exogenous and endogenous causes of DNA damage as well as a multitude of repair mechanisms to fix the damage; however, if it is not fixed, the damage becomes a permanent mutation. A series of these mutations lead to cancer. Deficient Nucleotide Excision Repair (NER) is being studied as one of the main mechanisms of carcinogenesis. Deficient NER was found in stage I breast cancers as compared to normal breast epithelium and may be due to over-expression of microRNA. In order to verify this …

Porphyrin Geometry- Associated Energy And Binding Conformation, Jessica Millar Apr 2013

Porphyrin Geometry- Associated Energy And Binding Conformation, Jessica Millar

Undergraduate Student Symposium

Meso substituted cationic porphyrins are large, naturally occurring macrocylces that are highly substituted, thereby giving them a wide variety of unique properties including the ability bind to DNA. The degree of distortion of these porphyrins caused by peripheral substitution can determine each molecules particular type of binding to DNA sequences. Previous studies have shown that highly substituted porphyrins with less planar conformations (such as saddle, ruffle, wave, etc.) often have a harder time binding to regions of DNA due to an increase in steric clashes and a larger destabilization of the strand. This experiment’s focus is the relationship between conformation …

Side-Bridge Hold Times Are Not Related To Injury Prevalence In Female Rowers, Amber Morrell Apr 2013

Side-Bridge Hold Times Are Not Related To Injury Prevalence In Female Rowers, Amber Morrell

Undergraduate Student Symposium

Rowing injuries are primarily overuse related and occur commonly to the knee, lumbar spine and ribs. Core tests of strength, stability and/or endurance are used in clinical practice to predict injury. The side-bridge hold test (SBH) is a valid and reliable test of core endurance with female norms of 75±.32 and 78±.32 seconds for right and left sides. The purpose of this study was to determine if SBH performance can predict core injuries (ribs, lumbar spine, hip, knee) in intercollegiate female rowers (ROW). A sample of convenience was utilized; 33 ROW free of recent musculoskeletal injury performed the SBH on …

Synthesis Of The Next Compound In A Homologous Series Of Metal-Organic Frameworks, Rachel Salveson

Undergraduate Student Symposium

Porous compounds, clays and activated charcoal, have been used as adsorbents in a number of different settings such contrast for x-rays in the medical field. Unfortunately, these adsorbents are not very selective and adsorb just about everything. A new class of adsorbents known as MOF's have become of great interest because these materials are easily altered synthetically and thus offer the promise of improved control over selectivity.

Our interest has been in the derivatives of NBAII, shown below. Notice that structure A has one six membered ring in the backbone while structure B has two. When crystals of these molecules …

The Importance Of Neurolysin In The Renin-Angiotensin System Of The Mouse Brain, Eduardo Carrera, Catalina Breton, Andrea Linares Apr 2013

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 Apr 2013

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 Apr 2013

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 Apr 2013

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 Apr 2013

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 Apr 2013

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 Apr 2013

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 Apr 2013

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 Apr 2013

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 …

The Effect Of Secondary English Proficiency On The Reading Strategies Of International Students, Natasha Vega-Valbuena Apr 2013

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 …

Cellular Life Beyond An Individual’S Death, Emily Schmitt Apr 2013

Cellular Life Beyond An Individual’S Death, Emily Schmitt

CAHSS Intellectual Conversations

One of the most famous examples of cell lines surviving long after a person has died comes from a tumor found in the body of Henrietta Lacks, who died of cervical cancer in 1950. The study of approximately 50 million tons of her cells, which would conservatively equal the amount of cells in one billion people, has resulted in nearly 11,000 patents, including the polio vaccine. These cells have become a focus of public attention since Rebecca Skloot’s 2010 book, The Immortal Life of Henrietta Lacks. This talk will discuss what happens to cells once they leave our bodies, …
