Reactive Oxygen Species Production During Oxidative Stress In Lymphoblastoid Cell Lines From Autistic Children, Hannah Mathew Apr 2016

Reactive Oxygen Species Production During Oxidative Stress In Lymphoblastoid Cell Lines From Autistic Children, Hannah Mathew

Undergraduate Student Symposium

Autism is a neurodevelopmental disorder that is characterized by deficits in social interaction, communication and repetitive behaviors. As the prevalence of the disorder increases, the need to understand the cause to account for its treatment increases. Besides the genetic factors that attribute to the cause, studies have examined other environmental factors that may lead to a diagnosis of autism. Children with autism are thought to be more susceptible to oxidative stress, which may contribute to the pathological nature of the disorder. Studies have shown nearly 35% of autistic children have low glutathione levels. Glutathione is an antioxidant that the body …

Science And Activism: Overcoming Stereotypes, Alexis Good, Kathleen Taylor Apr 2016

Science And Activism: Overcoming Stereotypes, Alexis Good, Kathleen Taylor

Undergraduate Student Symposium

There is a rift between environmentalists and environmental scientists brought on by societal stereotypes (Sissenwine). Environmentalists strive to advocate for environmental change; however, when they are defined by their stereotypes, their political movements are minimized by society so that they are no longer effective (Bashir). Environmental scientists often disengage from environmentalists because they do not want to obtain the associated stereotypes of these activists (Bashir). This is problematic because it prevents knowledgeable individuals from coming together in order to address the larger environmental problems in society (Castano, Paladino, et al). Therefore we will provide solutions that will allow environmentalists to …

Selective Stimulation Of At2 Angiotensin Ii Receptor Subtype Increases Neural Stem Cell Proliferation, Nadia A. Siddiqi, Brigitte Blanco, Leena Couling Apr 2016

Selective Stimulation Of At2 Angiotensin Ii Receptor Subtype Increases Neural Stem Cell Proliferation, Nadia A. Siddiqi, Brigitte Blanco, Leena Couling

Undergraduate Student Symposium

Angiotensin II is a potent hormone in the renin-angiotensin system that regulates blood pressure through vasoconstriction. Altered levels of angiotensin II has been linked to several diseases, such as kidney disease and stroke. The angiotensin II receptors, AT1 and AT2, have a similar affinity for angiotensin II. The AT1 receptor is found in heart, blood vessels, kidneys, lungs, and brain. The AT2 receptor is abundant in the fetus and neonate, but has a controversial role in the adult. Recently, the AT1 and AT2 receptors were found to be expressed in neural stem cells. As neural stem cells have a demonstrated …

Shedding Light On Banana Spiders In Urban Habitats, Ashley Lonergan Apr 2016

Shedding Light On Banana Spiders In Urban Habitats, Ashley Lonergan

Undergraduate Student Symposium

The Banana Spider, Nephila clavipes, is the largest non-tarantula spider species and commonly colonizes urban habitats. This species is an orb weaver, relying on trapping aerial prey in its large vertically oriented webs. Many nocturnally active insects are attracted to light sources found throughout urbanized areas. I hypothesize N. clavipes exposed to higher light levels in urban areas will be larger than individuals in darker natural areas. Forty nine spiders were observed and recorded; twenty four in natural areas and twenty-five in urban areas. For each spider the following was recorded: GPS coordinates, web height and diameter, size of …

The 'Triangle' Formula: A Role And Play Option Analysis Of The Triple-Post Offense, Tiffany Kelly Apr 2016

The 'Triangle' Formula: A Role And Play Option Analysis Of The Triple-Post Offense, Tiffany Kelly

Undergraduate Student Symposium

The triple-post offense, widely known as the triangle offense, has been accredited for producing 11 NBA championships, but has vanished from the league since the absence of all-time winningest coach, Phil Jackson, pre ‘14-‘15 season. With his return, there has been much interest in the offensive system and its functionality. However, there are more questions than answers surrounding the triangle offense when validating the reason for its success. Excluding the Golden State Warriors and New York Knicks in the current league season (’15-’16), the offense stands untouched by many teams due to the confusion in how it operates. This research …

The Effect Of Y15 And Curcumin On The Ovarian Cancer Cell Line Ovcar3, Nicole Coelho, Amanda Ramnot Apr 2016

The Effect Of Y15 And Curcumin On The Ovarian Cancer Cell Line Ovcar3, Nicole Coelho, Amanda Ramnot

Undergraduate Student Symposium

Curcumin gives turmeric, a spice derived from Curcuma longa, its yellow color. Previous studies have reported that curcumin inhibits the proliferation of multiple cancer cell types, including ovarian, pulmonary, brain, and breast cancer through various pro-apoptotic mechanisms. In advanced ovarian cancer, focal adhesion kinase (FAK), a tyrosine kinase, is overexpressed and contributes to cancer aggression and resistance. 1,2,4,5-benzene tetraamine tetrahydrochloride (Y15) is an inhibitor of FAK and combining it with curcumin shows promise in reducing the FAK activity in ovarian cancer. Therefore, in the current study, the cytotoxic effect of Y15 and curcumin in combination and alone on the …

The Impact Of Gender Inequality On Earnings Of Women In Stem Fields: Historical Evidence And Possible Solutions, Matthew Hoy, Teodora Suciu Apr 2016

The Impact Of Gender Inequality On Earnings Of Women In Stem Fields: Historical Evidence And Possible Solutions, Matthew Hoy, Teodora Suciu

Undergraduate Student Symposium

This study examines the current gender inequality in STEM fields, as well as its causes and some possible solutions. STEM–also known as the areas of science, technology, engineering, and math–are heavily male-dominated fields. The matter of gender inequality in these fields begins with gender separation during childhood and continues to the issue of the pay gap during adulthood. It is proven that currently women generate less capital than males in the same position in STEM fields, leading to a harsh divide between genders. Recent and relevant studies describing the statistics and explaining the reasons behind these gender and pay gaps …

The Loss Of Modernism In Nazi Germany, Taylor Duggan Apr 2016

The Loss Of Modernism In Nazi Germany, Taylor Duggan

Undergraduate Student Symposium

Modernism in Germany was ultimately detested, ridiculed, and outlawed by Adolf Hitler in Nazi Germany but in turn was the movement that assured his position in power. In the year 1929, an opportunist and German Art Society organizer, Feistal-Rohmedar, designed the artistic revolution within Germany and first introduced the thought regarding the extermination of modern artwork. Between the years of 1933 and 1937, the Third Reich and the German Art Society were also on a mission to rid Germany of Modernism and it wasn’t until 1936 that Modernism was completely ruled out. The Third Reich believed that artistic manifestation and …

Biosorption Of Metal Ions By Neochloris Minuta And Neochloris Alveolaris Alga Grown In Regular And Nitrogen Depleted Media, Sara Rodriguez Apr 2016

Biosorption Of Metal Ions By Neochloris Minuta And Neochloris Alveolaris Alga Grown In Regular And Nitrogen Depleted Media, Sara Rodriguez

Undergraduate Student Symposium

Heavy metals are the most hazardous pollutants present in industrial and domestic waste water. The conventional methods for metal ions removal from wastewater are limited by technical and economical barriers, especially when concentration of metals in the wastewater is low (<100 ppm). Therefore the search and development of efficient and low-cost metal removal processes is of great importance. In this research project, two strains of algae Neochloris minuta and Neochloris alveolaris were grown in two different growth media: one with high nitrogen content (+N) and the other which was completely nitrogen depleted (-N). Nitrogen depletion increases the algal lipid content whereas a +N media would allow for the algae to synthesize more proteins. The dried algae strains were then mixed for 1 hour with metal …

Measuring The Time Diffusion Of A Colored Gas In A Small Enclosed Container, Fernando Reachy-Guadarrama Apr 2016

Measuring The Time Diffusion Of A Colored Gas In A Small Enclosed Container, Fernando Reachy-Guadarrama

Undergraduate Student Symposium

The diffusion time measurement of colored gases in closed containers is extremely important for many experiments in chemistry. For example, we used the diffusion time (Δt) of iodine in air -inside a closed container- to calculate the free mean path (λ) of molecules by using the relation λ = (Srms)2/(≺υ≻δt); here ≺υ≻ is the average molecular speed of the gas and Srms can be reasonably estimate to be one-half of the predetermine height that the gas has to reach. The usual method to measure Δt for a vertically upward …

Quantitative Measurement Of Learning And Memory In Caenorhabditis Elegans In Response To An Engineered Nematicidal Bacterium, Krunal Patel, Natalie Neves Apr 2016

Quantitative Measurement Of Learning And Memory In Caenorhabditis Elegans In Response To An Engineered Nematicidal Bacterium, Krunal Patel, Natalie Neves

Undergraduate Student Symposium

Despite their global prevalence, there are very few strategies to prevent infections due to parasitic nematodes. Recent studies have shown that bacteria engineered using the principles of synthetic biology may serve as an alternative approach to intoxicating nematodes. While these engineered bacteria were initially shown to be relatively efficacious in intoxicating the model nematode Caenorhabditis elegans, the nematodes quickly learned to avoid the engineered bacteria through aversive associative learning, rendering them less effective as biocontrols. In this study, we sought to quantify the rate at which C. elegans learns to avoid the engineered nematicidal bacteria. Using nematode learning assays, …

Recovery Of Larval Strongylid Nematodes From Raccoon, Procyon Lotor, Hema Narlapati, Rebekah St. Godard Apr 2016

Recovery Of Larval Strongylid Nematodes From Raccoon, Procyon Lotor, Hema Narlapati, Rebekah St. Godard

Undergraduate Student Symposium

A major challenge in the development of biocontrol methods targeting intestinal helminths is the lack of readily available strongylid experimental models that are also noninfective to humans. Noninfectivity to humans (and other nontarget organisms) is an important criterion for such models as this allows them to be used experimentally with minimal biosecurity measures, in standard laboratory settings. Preliminary laboratory work on raccoon feces in the context of an undergraduate parasitology course indicated that local raccoons are host to a specialist strongylid, Arthrocephalus lotoris, which only infects raccoons and skunks. Athrocephalus does not directly penetrate into its host, but must …

The Linguistics Of Terrorism, Leigh-Ana Mumford Apr 2016

The Linguistics Of Terrorism, Leigh-Ana Mumford

Undergraduate Student Symposium

With the inequities present around the world, the nature of terrorism is both puzzling and ruinous. What remains irrefutable about terrorism is how its connotation translates into its accepted definition. Political rhetoric often utilizes “terrorism” to create a narrative, often to justify the use of state violence to preserve “national security.” This research investigates to what extent the definition of terrorism has been altered to serve as a mask for naked self-interest by the US state and political elites. Emphasis will be placed on spikes of anti-terrorism rhetoric in US foreign policy since the 1980’s. Three case studies display the …
