Invegstigating The Causes Of Antibiotic Resistance In A Periodic Environment, Haley Mckissack, Uzair Mohammed, Kyle Cahill, Steven Thomas Apr 2015

Invegstigating The Causes Of Antibiotic Resistance In A Periodic Environment, Haley Mckissack, Uzair Mohammed, Kyle Cahill, Steven Thomas

Undergraduate Student Symposium

Misuse of antibiotics, coupled with a lack of new antibiotics being discovered, has threatened our ability to treat bacterial infections. Confounding our ability to effectively combat antibiotic resistance is the myriad of ways in which bacteria can resist antibiotic treatment. One mechanism is the inoculum effect, a phenomenon in which the inhibitory concentration of an antibiotic increases with initial cell density. Previously acquired data has indicated a mutation exclusive mechanism by which resistance arises. However, it is currently unknown as to whether or not the generation of antibiotic resistant bacteria due to spontaneous mutation plays a role in the inoculum …

Induction Of Apoptosis By Jfd-Ws In Human Breast Adenocarcinoma Xenograft Implanted Athymic Nude Mice, Janelle Alvarez, Meera Bhalani, Thanigaivelan Kanagasabai Ph.D., Sivanesan Dhandayuthapani Ph.D., Appu Rathinavelu Ph.D.

Undergraduate Student Symposium

Apoptosis (programmed cell death) can be stimulated when a cell has reached its pre-determined lifespan. The intrinsic pathway is typically activated for cell cycle regulation, thus preventing tumor formation. Bcl-2 family proteins can play a pro or anti-apoptotic role by regulating the expression levels and modes of action of other proteins such as caspases, which cleave cell parts until the cell is no longer functional. Many studies are focusing on proteins that regulate the apoptotic pathway, as anomalies may lead to tumor formation. The purpose of this study was to assess effects of a novel water-soluble cancer drug, known as …

Modeling And Simulation Of Caenorhabditis Elegans Chemotaxis In Response To A Dynamic Engineered Bacteria, Divya Pandya Apr 2015

Modeling And Simulation Of Caenorhabditis Elegans Chemotaxis In Response To A Dynamic Engineered Bacteria, Divya Pandya

Undergraduate Student Symposium

Parasitic helminthes remain important causative agents of human, plant and animal diseases. Helminthes seek out food sources and navigate toward potential hosts using olfaction of simple chemical cues, a process called chemoattraction. While several studies have examined how nematodes, including Caenorhabditis elegans, behave in response to a chemoattractant, how the characteristics of the chemoattractant affect worm behavior has yet to explored. In this manuscript, we develop a mathematical model to examine how characteristics of common chemoattractants affect movement and behavior in the model nematode C. elegans. Specifically, we model a scenario where a toxic, engineered bacteria designed to …

Nova Southeastern University's Participation In Many Labs 3: Evaluating Participant Pool Characteristics Across The Semester Via Replication, Guy Merus, Andrea Moran, Boglarka Varga, Stephanie Ponce, Idania Elizabeth Cater, Alexis Murphy

Undergraduate Student Symposium

A crowdsourced project from 23 university participant pools, including NSU (total N = 2,696; NSU N = 131), examined variation in 10 well known psychological findings and 8 individual difference measures over the course of the academic semester. Undergraduate psychology participant pools serve as a major resource for behavioral research studies. Many researchers have hypothesized that the traits and attentiveness of student research participants vary across an academic term (e.g., students who participate later in the semester may be lower in conscientiousness and higher in openness to experience). However, there is very little systematic evidence regarding the magnitude of such …

Posture And Cognition, Jana Mrkaja Apr 2015

Posture And Cognition, Jana Mrkaja

Undergraduate Student Symposium

This experiment examined how priming and posture influence attention. Previous experiments have shown that different body postures can influence cognitive focus and task performance. For instance, participants adopting an unfocused posture were slower at performing a visual search task (Chisholm, Risko, Evan, & Kingstone, 2013). However, this could be due to the effects of priming on attention (Bargn, Chen, & Burrows, 1996). In the current experiment, participants adopted either a focused leaning, forward upright or an unfocused, back slouched posture. Furthermore, participants were either primed or not primed by indicting that the posture will either increase or decrease their attentional …

Spiritual And Supernatural Elements Of English Theatre (1550-1612), Mariah Busk Apr 2015

Spiritual And Supernatural Elements Of English Theatre (1550-1612), Mariah Busk

Undergraduate Student Symposium

In “Spiritual and Supernatural Elements of English Theatre (1550-1612)”, I use four plays to examine the secularization of supernatural elements of English theatre during the High Middle Ages and the Early Modern Period. My research shows that in Everyman (c.1500) by Anonymous, The Tragical History of Dr. Faustus (c. 1588) by Christopher Marlowe, Hamlet (c. 1600) by William Shakespeare, and The White Devil (c.1612) by John Webster good and evil characters digress from being religious, spiritual figures to being humanized representations of these figures. Corresponding to this secularization is the loss of a God-like figure and a more common use …

The Dark Side Of Mind Wandering: Examining The Impact Of Emotionally Valenced Task Unrelated Thoughts On Working Memory, Audrey Hood, Samantha Gestido, Abraham Yacaman Apr 2015

The Dark Side Of Mind Wandering: Examining The Impact Of Emotionally Valenced Task Unrelated Thoughts On Working Memory, Audrey Hood, Samantha Gestido, Abraham Yacaman

Undergraduate Student Symposium

Working memory (WM) is a dynamic system responsible for maintaining and processing information, and controlling attention (Engle & Kane, 2004). Although WM remains stable during adulthood, it is altered by a variety of factors including affect (Ilkowska & Engle, 2010). However, there remains debate regarding whether the impact of affect on working memory is driven by positive or negative affect. For instance, negative affect impairs WM performance due to increases in Task Unrelated Thoughts (TUTs; Curci, Lanciano, Soleti & Rime, 2013). High levels of TUTs reduce performance on a variety of cognitive functions, including sustained attention (McVay & Kane, 2009) …

Temperature Dependent Variation In Self-Reported Contagious Yawning Within A Single Season, Melissa Dauzonne, Yana Prilutskaya, Daniel Garcia, Amani Al Barghouti Apr 2015

Temperature Dependent Variation In Self-Reported Contagious Yawning Within A Single Season, Melissa Dauzonne, Yana Prilutskaya, Daniel Garcia, Amani Al Barghouti

Undergraduate Student Symposium

Previous cross-cultural research on humans has shown that self-reported contagious yawning frequency varies between distinct seasons and climate conditions. However, it remains possible that differences in yawning across seasons may be a result of physiological circadian changes across the year. In attempt to address this question, here we discuss the results of a study investigating the variation in the frequency of self-reported contagious yawning within a single season in one geographic location. A total of 142 pedestrians were recruited outdoors during an 18-day period over the summer in an equatorial monsoon climate in southern Florida, USA. Consistent with the thermoregulatory …

The Function Of Yawning In Reducing Acute Hyperthermia Following Physiological Stressors, Melissa Dauzonne, Yana Prilutskaya, Daniel Garcia, Amani Al Barghouti Apr 2015

The Function Of Yawning In Reducing Acute Hyperthermia Following Physiological Stressors, Melissa Dauzonne, Yana Prilutskaya, Daniel Garcia, Amani Al Barghouti

Undergraduate Student Symposium

The present study attempts to look at the extent to which yawning reduces stress induced acute hyperthermia. When stressed socially or physiologically, body temperature rises with the stressed subject experiencing acute hyperthermia, essentially inducing a brief fever. Thus, after the removal of the stress stimulus, body temperature should begin to decrease and return to baseline conditions, which may be achieved through various thermoregulatory mechanisms. One such mechanism is yawning. Yawning is a deep inhalation of air accompanied by rapid increases in blood flow around the face head and neck. As supported in recent research across a wide range of taxa, …

Why Do Patients Who Are Going Blind Lose Their Blue Color Vision First?, Mariana Ferraz Apr 2015

Why Do Patients Who Are Going Blind Lose Their Blue Color Vision First?, Mariana Ferraz

Undergraduate Student Symposium

Retinitis pigmentosa (RP) is a slowly progressive, inherited retinal degeneration affecting roughly 1 in 4000 people, typically resulting in a loss of peripheral and night vision, with most legally blind by age 40[1] . RP is characterized by the apoptosis of retinal rods and cones (photoreceptors). Cones are responsible for central and color vision, while rods provide peripheral and nighttime vision. Over 20 years ago, it was reported that some RP patients initially lose short wavelength cones (i.e., s-cones for blueviolet colors; e.g., imagine a world in which shades of blue look grey), but no further research on this …

Attractiveness Perception And The Influence Of Mate Availability, Ashley Stelmaszek, Mariah Chadukiewicz Apr 2015

Attractiveness Perception And The Influence Of Mate Availability, Ashley Stelmaszek, Mariah Chadukiewicz

Undergraduate Student Symposium

Psychological studies on the perception of facial attractiveness have shown that attractiveness perception can be influenced by nonphysical factors, such as relationship status and limited or plentiful availability in the mating pool (Kniffin, K; Wilson, D, 2004), (Madey, 1996). The focus of the present study is to examine perception of physical attractiveness when presented with a manipulated verbal cue that gives an illusion of either a limited or plentiful population of mates. We want to determine if the participants will adjust their perceptions of physical attractiveness when it is implied that there is a limited selection of mates. We hypothesize …
