Synthesis And Characterization Of Tris(4,4-Dichloro-2,2-Bipyridine) Ruthenium (Ii), Jack Bence Apr 2017

Synthesis And Characterization Of Tris(4,4-Dichloro-2,2-Bipyridine) Ruthenium (Ii), Jack Bence

Undergraduate Student Symposium

A new ruthenium (II) [Ru(4,4-dichloro-2,2-bipy)3] Cl2 complex has been synthesized using a new procedural method. The complex was characterized by NMR, IR, and UV-Vis. After purification through column chromatography with alumina, the percent yield was 60.39%. Electrochemistry data confirmed the presence of Ruthenium- bipyridine bonds, very similar to electrochemical data of [Ru(bpy)3]Cl2. The quantum yield of the [Ru(4,4-dichloro-2,2-bipy)3] Cl2 complex was calculated after comparing with calibrated standards. This complex will be used to improve the photosensitizingproperties of the complex by adding auxiliary ligands to the chlorinated bipyridine group.


Realizing Identity Through Reflection: Walt Whitman’S Song Of Myself, Sierra Sandler Apr 2017

Realizing Identity Through Reflection: Walt Whitman’S Song Of Myself, Sierra Sandler

Undergraduate Student Symposium

This oral presentation investigates pronoun choices and environmental imagery in Walt Whitman’s Song of Myself through direct analysis of stanzas. In exploring why Whitman wrote what he wrote, using such diction as “I”, “me”, “myself”, “you”, and “Walt Whitman”, this presentation analyzes the poem in hopes of teaching others what they can learn from his writing, as well as their own. With the influence of Transcendentalism pushing Whitman to view his life on a much larger scale, he reveals facets of his character that each add a different layer to how he perceives himself and how he wants to be …

Screening For Type Iii Secretion System Inhibitors, Samir Nacer, Kendall Mockridge, Kevin Lujan, Chris Soha, Eugenia Jimenez

Undergraduate Student Symposium

Commonly used antibiotics are becoming less effective because they target bacterial cell walls or processes, which create a selective pressure for bacteria to become resistant, leading to the formation of “super bugs”. Some of these pathogenic bacteria include E. coli, Salmonella, Chlamydia and Yersinia. These species utilize a type III secretion system (T3SS), which are needle-like structures on their surface used to inject host cells with toxins in order to evade our immune system and cause infection. Recently a new method for testing compounds to determine if they inhibit the Y. pestis T3SS was developed by our lab. This method …

Cytotoxic Effect Of Iphinoe: A Marine Natural Product On Lncap Prostate Cancer Cells, Simran Agarwal, Deepthi Gangaram

Undergraduate Student Symposium

Prostate cancer is one of the most common forms of cancer among men in the United States. It is estimated that one in every three men will develop prostatic intraepithelial neoplasia, among them one in six will progress to carcinoma of the prostate. Surgery, radiation therapy, and chemotherapy are commonly sought-after treatments for prostate cancer. However, recently there has been a growing number of discoveries reported in favor of the chemopreventative abilities of natural products. Therefore, the primary focus of this study was to determine the cytotoxic effect of Iphinoe extract (IE) from marine cyanobacteria, on LNCaP prostate cancer cells. …

Catfish Get Caught And Punished: Dating Profile “Cheaters” And Mate Value Ratings, Gianpaolo Stasi, Mariana Brinkerhoff, Danielle Sampson, Widline Nordelus

Undergraduate Student Symposium

People who break social rules by trying to take more than their fair share are often singled out and punished by those around them. Although this phenomenon has been studied across a wide range of human behaviors, it has not yet been investigated in one situation in which people are consistently trying to "get more than they deserve": dating. This study tested the extent to which people may punish those potential romantic partners who falsely present themselves as valuable mates. Participants completed a task in which they (1) read a fictitious online dating profile that described a person as having …

Assessment Of Heavy Metals In Subsistence-Harvested Alaskan Pinniped Vibrissae, Chitra Gotluru

Undergraduate Student Symposium

In the past 40 years, three species of pinnipeds -harbor seal (Phoca vitulina), Steller sea lion (Eumetopias jubatus), northern fur seal (Callorhinus ursinus) and the northern sea otter (Enhydra lutris) have undergone significant population declines . Archived vibrissae (whiskers) from these four species from the Bering Sea and throughout the Gulf of Alaska from 1993 to 2014, are used in the project. To our knowledge, this is the first time that whiskers are being used for heavy metal analyses. Whiskers are comprised of keratin, much like fur and hair, which has been proven to accumulate heavy metals. The heavy metals …


Behavioral Response Of Small Everglades Fish To Hydrological Variation, Predator Cues And Parasites, Stacey Spadafore, Domenique Olesen Apr 2017

Behavioral Response Of Small Everglades Fish To Hydrological Variation, Predator Cues And Parasites, Stacey Spadafore, Domenique Olesen

Undergraduate Student Symposium

Small fish are important to the Everglades ecosystem as primary and secondary consumers and as a food source for higher trophic levels. In short-hydroperiod wetlands, these fish must migrate to refuge areas or risk stranding, and have been observed to rapidly recolonize during the wet season. The goals of this study are to understand what influences annual migrations to and from short-hydroperiod wetlands. We aim to link individual variation in behavior to population-level movement. We specifically tested whether the willingness of fish to explore and move through unknown environments varied among species, with hydrological season, wetland hydroperiod, or parasite load). …

Comparison Of Porifera Bacterial Symbiont Community Profiles Based On Species And Source Template, Celeste Banfill Apr 2017

Comparison Of Porifera Bacterial Symbiont Community Profiles Based On Species And Source Template, Celeste Banfill

Undergraduate Student Symposium

Sponges exhibit complex, species-specific microbial symbioses. The role of symbiont communities, known as “microbiomes”, to create a “holobiont” with their host is not fully understood. Microbiomes can be characterized by sequencing 16S rRNA fragments from total community genomic DNA (gDNA). The purpose of this study is to sequence bacterial rRNA from previously isolated cDNA (complementary DNA synthesized from RNA samples) and compare the profiles to gDNA. The samples were derived from the Porifera Tree of Life (PorTol.org). I hypothesize that microbial profiles derived from gDNA templates will be nearly identical to those found in cDNA of the same sponge species. …

Continuous Dependence And Differentiating Solutions Of A Second Order Boundary Value Problem With An Average Value Condition, Samantha Major, Kaitlyn Seabrook

Undergraduate Student Symposium

Using a few conditions, continuous dependence, and a result regarding smoothness of initial conditions, we show that derivatives of solutions to the second order boundary value problem y''=f (x, y, y'), a < x < b, y (x1) = y1, 1 d-c ∫ c d y(x)dx = y2, a < x1 < c < d < b, y1, y2 ∈ ℝ with respect to each of the boundary data x1, y1, y2, c, d solve the associated variational equation with interesting boundary conditions. Of note is the second bundary condition with an average value condition.


Does Stress Hurt Everyone? Individual Differences In Susceptability To Psychosocial Stressors, Lauren Gispert, Alyssa Boltson, Samantha Rodriguez Apr 2017

Does Stress Hurt Everyone? Individual Differences In Susceptability To Psychosocial Stressors, Lauren Gispert, Alyssa Boltson, Samantha Rodriguez

Undergraduate Student Symposium

Despite the critical role working memory plays in controlling attention, when people experience negative or stressful life events working memory task performance is impaired (Klein & Boals, 2001). Further, daily variation in stress corresponds to variation in working memory performance (Sliwinksi, Smyth, Hofer, & Stawski, 2006). In contrast to robust findings that stress impairs working memory, recent evidence suggests there are individual differences in susceptibility to stress manipulations (Plieger, et al., 2016). To examine this, the current study randomly assigned one hundred NSU undergraduates to either a speech or control condition. Participants in the speech condition gave a threeminute speech …


Dollar, Brianne Bailey, Grace Ducanis Apr 2017

Dollar, Brianne Bailey, Grace Ducanis

Undergraduate Student Symposium

Although many of us live seemingly unconnected lives, separated by social and economic stratospheres, we are often linked through commonplace objects and locations. A dollar bill, for example. A dollar bill survives an average of 5.9 years, according to the Federal Reserve. By some estimations, it can change hands 110 times a year. And while a dollar’s economic value doesn’t change much from wallet to wallet, a dollar can change the people who carry it.


Don't Hug Me I'M Scared: Sense Or Cents?, Adam Deross Apr 2017

Don't Hug Me I'M Scared: Sense Or Cents?, Adam Deross

Undergraduate Student Symposium

In 2011, British artists Becky Sloan and Joseph Pelling released the first episode of what would become a viral YouTube sensation. The short film series “Don’t Hug Me I’m Scared” has over 42 million views on its first episode alone. I completed an analysis paper on the series putting forth my explanations and theories on the small details and plotline of the ambiguous and open series. Through my oral presentation, I aim to help others think a little bit more critically about this art form and what implications it holds for the real world.


Evaluation Of Fak And Mdr1 Crosstalk In Platinum Resistant Ovarian Cancer Cells, Keerthi Thallapureddy Apr 2017

Evaluation Of Fak And Mdr1 Crosstalk In Platinum Resistant Ovarian Cancer Cells, Keerthi Thallapureddy

Undergraduate Student Symposium

Platinum resistance continues to be a major challenge in the chemotherapeutic management of ovarian cancer. Increased phosphorylation of a tyrosine kinase, Focal Adhesion Kinase (FAK) has been implicated in the development of this platinum resistance. A multidrug resistant gene (MDR1) codes for the P-glycoprotein, a protein that plays an important role in the chemotherapeutic resistance of the platinum resistant ovarian cancer cells. Therefore, it was suspected that there may be an intracellular link between FAK and MDR1 that can determine the drug resistance and consequent escape from the cytotoxicity of the drugs in ovarian cancer cells. Hence, it is hypothesized …


Examining The Stress-Gut Microbiome Interface In A Human Population, Eileen Davidson, Reaghan May, Sarah Lyle Apr 2017

Examining The Stress-Gut Microbiome Interface In A Human Population, Eileen Davidson, Reaghan May, Sarah Lyle

Undergraduate Student Symposium

Diverse symbiotic microbial communities are harbored on and within most eukaryotic host organisms, including humans as “microbiomes”. The human gut microbiome represents one of the best-studied microbial communities in nature. Recent research on the gut has indicated that the microbiome can influence human behavior, metabolism, and disease states. However, it currently remains unclear as to how the diversity in the gut microbiome may affect stress. To address this open question, we sought to sample gut microbiome from two populations of participants: stressed and non-stressed males. Neurobehavioral measures of emotion processing and cognition were assessed through the NIH Toolbox platform and …


Fluorinated Porphyrin Interactions In Cancer Cells, Brandon Golub, Rony Saleeb Apr 2017

Fluorinated Porphyrin Interactions In Cancer Cells, Brandon Golub, Rony Saleeb

Undergraduate Student Symposium

Photodynamic therapy is a contemporary cutting-edge cancer treatment that is currently being studied intensely. A common agent used in photodynamic therapy is a manufactured porphyrin molecule. Porphyrin molecules are activated when exposed to specific wavelengths of light, and upon activation, either cellular apoptosis or tissue necrosis occurs. Through the alteration of the chemical structure of a porphyrin molecule, differing outcomes take place in the development of the cancer treatment. Careful examination of fluorinated porphyrin derivative compounds can be implemented in order to determine applicable compounds for treatment.


Galaxy Morphology Classification System, Lennox Francis Apr 2017

Galaxy Morphology Classification System, Lennox Francis

Undergraduate Student Symposium

Citizen scientists are becoming more and more important in helping professionals working through big data. An example in astronomy is crowd sourced galaxy classification. But how reliable are these classifications for studies of galaxy evolution? We have created a tool that allows us to use crowd sourced data from college students to investigate morphological classifications and compare the data against existing professional classifications. User generated data is prone to error and comparing said data against a professional classification allowed us to establish a margin of error, which we then corrected using machine learning. The program was coded using C++, the …


How Peripheral Substitutions Affect Porphyrin Basicity, Alfredo Lam, Fady Guigati Apr 2017

How Peripheral Substitutions Affect Porphyrin Basicity, Alfredo Lam, Fady Guigati

Undergraduate Student Symposium

Using H2TPP as a central reference, a set of proton competition studies of free base octa alkyl and meso substituted porphyrins were carried out. The H2TPP was selected since it has a large absorption for dication at 650 nm. The octa alkyl substituted porphyrins used in this study were H2OEP, H2OMP and H2etiol; selected because they are a good representation of natural occurring porphyrins. H2TPP, H2TBPP, H2DPP, and H2TTFMPP, using different arrangements on substitution, where also investigated to further study their meso …


Impact Of Mdm2 On The Expression Level Of Xiap On Various Cancer Cell Lines, Kyle Bolston, Christopher Garcia Apr 2017

Impact Of Mdm2 On The Expression Level Of Xiap On Various Cancer Cell Lines, Kyle Bolston, Christopher Garcia

Undergraduate Student Symposium

Transcription of the mouse double minute 2 homolog (MDM2) gene is amplified during cancer development and continues through disease progression. X-linked inhibitor of apoptosis protein (XIAP)- MDM2 heterodimerization occurs when XIAP binds to the RING domain of the MDM2. This interaction is a pro-cancerous mechanism, which counteracts the cellular stress caused by cancer therapy, and plays a significant role in the stabilization of MDM2 and related functions. Additionally, XIAP inhibits the pro-apoptotic proteins caspase 3, 7 and 9; which are key factors in intrinsic cellular apoptosis. The objective of the study is to test the effect of MDM2 inhibitor RG7388 …


Improving Functional Movement Patterns Reduces Pathomechanics In Competitive Distance Runners, Shivani Wood, Victoria Rushia, Natalie Bedell Apr 2017

Improving Functional Movement Patterns Reduces Pathomechanics In Competitive Distance Runners, Shivani Wood, Victoria Rushia, Natalie Bedell

Undergraduate Student Symposium

Running related injuries are linked to faulty running biomechanics such as excessive hip adduction (HADD), hip internal rotation (HIR), knee valgus (KVAL), and contralateral pelvis drop (CPD). Functional movement pattern (FMP) training is a novel intervention used by clinicians to correct underlying FMPs (stepping, squatting) with the aim of affecting more sport specific mechanics. The purpose of this study was to evaluate the effectiveness of an 8-week FMP corrective program to reduce pathomechanics in six runners with dysfunctional FMPs. We used paired t-tests to evaluate changes in peak motion in degrees for HADD, HIR, KVAL, and CPD; and total Functional …


Investigation Of Fecal Contamination Of Urban Tidal Flood Water In Southeast Florida, Hyo Won Lee Apr 2017

Investigation Of Fecal Contamination Of Urban Tidal Flood Water In Southeast Florida, Hyo Won Lee

Undergraduate Student Symposium

Since many diseases can spread through water-borne transmission, water quality management is a big part of public health. Contamination of water by exposure to human or animal feces represents a potentially high public health risk for spread of fecal related pathogens. Thus, good water quality management seeks to better ensure the cleanliness and safety of water that people and the environment are exposed to. Due to sea level rise, tidal flooding is becoming an increasingly serious problem for coastal populations, a result of more frequent flooding of contaminated coastal landscapes. Therefore coastal flooding is a problem due to both the …

Isolation And Characterization Of Antibiotic Producing Bacteria From Storm Water Treatment Areas, Kayla Catellanos-Bristol, Taura Khorramshahi, Anupsinh Chauhan

Undergraduate Student Symposium

With the diminishing supply for new antibiotic drugs to fight the rising number of infections caused by drug-resistant pathogens, a novel program called the Small World Initiative (SWI) was developed. SWI is a collaborative research effort that combines scientific education with research. The research is performed by undergraduate students from select Universities throughout the world. The majority of antibiotics in current use originate from soil dwelling bacteria; thus, discovery of new antibiotics produced by soil microbes is used as a scientific driver to combat the antibiotic crisis. Microorganisms present in soils should change with the concentrations of nutrients found in …

Low Vision Patients' And Providers' Satisfaction With Telerehabilitation, Alisha Trivedi, Tony Succar, Pat Yoshinaga, Angie Bowers, John Shepherd, Nicole C. Ross

Undergraduate Student Symposium


Purpose: A recent systematic review found no publications with results on the topic of telerehabilitation for low vision (LV). Our goal was to develop and evaluate components to deliver LV telerehabilitation services. Methods: Three LV providers conducted telerehabilitation sessions from their office with eight visually-impaired adults in their homes. Subjects received a hand-held magnification device for reading, and self-reported difficulty with returning for a follow-up at their provider's office. We obtained providers’ ratings for the use of hardware devices (i.e., iPad and Android tablets) and commercially available, HIPAA compliant, secure videoconference software (zoom.us) during telerehabilitation sessions at which subjects received …
