Examination Stress Can Enhance Long Term Memory Performance, Randy Denis, Kara Faso

Undergraduate Student Symposium

The literature is currently unclear regarding the hypothalamic-pituitary-adrenal (HPA) axis activation during examination periods. In addition, it is uncertain if a potential increase in cortisol influences memory processes during an academic examination. Here, we seek to better understand the complex relationship between examination stress and memory by testing both short-term and long-term memory 3 weeks prior to an examination period and then 15 minutes prior to an examination. We also assessed subjective measures of stress through self- report assessment of stress and physiological measures of stress through salivary cortisol levels during both periods. We found that participants reported to be …

Establishing A Control Of Gene Expression In Yeast Exposed To A Standard Environment As A Comparison To Yeast Exposed To Flu Vaccine With And Without Thimerosal, Christie Rubio

Undergraduate Student Symposium

Gene expression in Saccharomyces cerevisiae (Baker‘s yeast) was assessed using microarray technology. After growing the yeast in standard conditions (YEPD media), the total RNA was extracted using the Ambion RiboPure Yeast Kit. The quality and quantity of the RNA was assessed using gel electrophoresis and UV spectrophotometry. Next, mRNA (approximately 1% of the total RNA) was isolated using reverse transcription reactions. cDNA was made from the mRNA by amplifying a gene that should always be expressed (TDHI) using Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). Several key genes that are hypothesized to be affected by thimerosal in vaccines were also tested …

Dna Fingerprinting And Whole Genome Replication For The Identification Of Bacteria, Justin Piacentino, Shilpa Kailas

Undergraduate Student Symposium

Prokaryotes are typically clonal in nature due to their rapid reproduction by binary fission, but some molecular genetics methods exist to differentiate various bacterial species. In this experiment, common bacteria were grown in nutrient broth before their DNA was extracted. Repetitive DNA sequences that are universal to a variety of bacteria were then targeted in the polymerase chain reaction (REP-PCR) using ERIC primers.The bacterial DNA was then quantified using gel electrophoresis to form a ―fingerprint‖of distinct bands for each bacterial species. The Repli-g procedure was then performed to amplify the amount of DNA going into the REP-PCR replication, while testing …

Dizzying Duplicity: Women's Dance Of Discord, Amanda Allen Thompson

Undergraduate Student Symposium

An examination of Dorothy Parker's "The Waltz" and Tillie Olsen's "Tell Me a Riddle " reveals a telling commonality: the cyclical redundancy that characterizes women's lives in early to mid-period twentieth century America.. Dorothy Parker's piece is an amusing allegorical short story in which the protagonist finds herself dancing with a partner with whom she secretly would prefer not to dance. However, such an option is unavailable to women in polite society. Parker's narrator/protagonist is internally impudent but externally compliant as her rebellion eventually dissipates and she dances her life and her autonomy away. Olson‘s "Tell Me a Riddle" tells …

Coral Cover Of Diaseris Distorta And Porites Sverdrupi At Isla Catalana, Gulf Of California, Mary Crider

Undergraduate Student Symposium

Diaseris distorta is a free-living, solitary fungiid coral that mostly inhabits sand or mud habitats surrounding coral reefs. It is distributed throughout the tropical waters of the Red Sea, Indian Ocean, and Pacific Ocean.

Blockage Of Vegf-Induced Angiogenesis With A Novel Anti-Angiogenic (Jfd) Drug, Crystal Romero

Undergraduate Student Symposium

Vascular Endothelial Growth Factor (VEGF) is frequently expressed in several pathological tissues and is known to promote angiogenesis and vasculogenesis in highly metastatic cancers. The purpose of this experiment was to re-evaluate the efficiency of JFD drug, in varying concentrations, on the capillary formation by HUVEC cells. To accomplish the intended purpose an In-Vitro Angiogenesis assay kit was utilized to examine capillary formation by HUVEC cells. Approximately 5 x 10³ HUVEC cells were seeded into matrigel, which simulates an endothelial cell matrix, on a Petri- dish. To these plates different concentrations (0.1μM, 0.25 μM, 0.5 μM, 2.5 μM, and …

An Examination Of The Specific Functions Of Three Cancer Drugs (Methotrexate, Fluorouracil, And Taxol) And Their Expected Effects On Gene Expression, Neena Chandrasekaran

Undergraduate Student Symposium

Cancer is a term used to define many diseases in which a group of cells exhibit uncontrolled growth, invasion, and sometimes metastasis. In this literature review project, the mechanisms of action for three drugs used to treat cancer by inhibiting cell division: Ledertrexate (methotrexate), Fluorouracil (adrucil), and Paclitaxel (taxol) are examined. Methotrexate inhibits an enzyme called dihydrofolate reductase (DHFR) that catalyses the conversion of dihydrofolate to folic acid, needed for the synthesis of the nucleoside thymidine, and also purines which are required for DNA synthesis. Fluorouracil functions as a thymidylate synthase inhibitor by stopping the synthesis of the pyrimidine, thymidine, …

A Study Of New Porous Molecular Frameworks And Their Adsorption And Desorption Properties, Sam Aminov, Jennifer Tejada

Undergraduate Student Symposium

Metal-organic Frameworks (MOF‘s) are porous materials comprised of organic buildingblocks bound to metal atoms. These compounds are finding applications in various fields of study including gas absorption, catalysis of specific reactions, and in drug delivery among others. Our emphasis has been placed on synthesizing and characterizing new frameworks with the use of bisl(arylimino)isoindolines (BAII‘s) as building blocks. Oneof these, NBAII(CuOAc), produced by reaction of NBAII with copper acetate, was analyzed for small molecular absorption and desorption. This particular framework was successful in the absorption of carbon tetrachloride and chloroform but failed to absorb pentane and toluene, while other organic solvents …

Acid Rain: Adversity On Atmospheric Carbon, Andrew Lister, Hannah Bromberg, Kayla Mancuso

Undergraduate Student Symposium

―Acid Rain is the deposition of wet and dry acidic pollutants that have been shown tocause damage to the environment. Dissolved atmospheric carbon dioxide in clouds and rain undergoes a chemical reaction with water to form carbonic acid, thereby changing the pH of unpolluted rain water from 7.0 to 5.7. When unpolluted rain acquires additional acidity through the reactions of air pollutants with water, stronger acids are formed. Deposits from acid rain on the earth‘s surface have adverse effects on oceans,forests, soils, organisms, buildings and mankind. Acid rain clearly has an adverse affect on the carbon cycle of the atmosphere.

Predictors will be tested for significance, model assumptions will be checked, and model diagnostics will be used to …

Bending Under Pressure: "In-Vision" It’S Plain To See, Megan Oswald

Undergraduate Student Symposium

"It is not what you look at that matters, it is what you see." –Henry David Thoreau

Vision is key to the human experience. It is often the first sensation received for environmental navigation. While to the average eye images may be clear, ocular disorders can distort their production, making the study on ocular disorders essential. Glaucoma is characterized by damage to the optic nerve due to excessively high intraocular pressure (IOP). It is assumed that IOP is uniform throughout the eye. Therefore we can link glaucoma to the deformations of the cornea, which is the oculardisorder of astigmatism inhibiting …

This research examines the quality of political polling during the presidential primary election season in an effort to predict which political polls would be most accurate in the general presidential election. This analysis was done using thousands of political polls from across the United States that were released to the public from a variety of sources. The statewide primary election polls themselves differed in a variety of ways and the data was stratified by many factors including: which …

Trashing The Past: Butch And Femme Labels In The Lesbian Community, Nicole Donia

Undergraduate Student Symposium

Since the 1970‘s, there has been an ongoing argument within the lesbian community over whether the genders butch and femme should be rejected or embraced. Some lesbian feminists and now queer theorists have gone to great lengths to convince lesbians to reject the labels of butch and femme. They claim that lesbians of the past were forced into these gender roles because of the necessity to conform to a heterosexist society. On the other hand, scholars of gay and lesbian cultural studies oppose the rejection of these genders based on the importance they have played in lesbian history. After a …

The Effects Of Laughter On Attention, Sabrina Smith

Undergraduate Student Symposium

Laughter is a fundamental element of human behavior. Although numerous studies have demonstrated the benefits of laughter, the effect of laughter on attention is currently unknown. Attentional resources are required to provoke the reaction of laughter, therefore, in instances where a cognitive task occurs in parallel with humorous stimuli (i.e. attention is dually allocated), there is potentially a competition for attentional resources. This competition may result in reduced cognitive abilities during laughter. This study will utilize brain electroencephalographic (EEG) event related potentials (ERPs) to measure attentional processing during concomitant humorous exposure or nonhumorous exposure. Specifically, we will utilize two videos …

From Failed Unity To Long-Term Division: The Impact Of Nineteenth-Century French Diplomacy On Haitian-Dominican Relations, Geneviève Chantal Volcy Céant

Undergraduate Student Symposium

Haiti and the Dominican Republic are sometimes referred to as two wings of the same bird. However, to Dominicans the island is Quisqueya while Haitians refer to it as Hispaniola. This distinction offers a symbolic illustration of their opposing attitudes, which are usually explained as cultural differences. In this paper, I take into consideration the historical roots of these difficulties and in particular the role of France during the post-colonial era. French diplomats invested in and exploited the island's political instability, driving the two populations apart. The research presented in this paper addresses the negative impact of nineteenth-century French diplomacy …
