Improvement Of Trauma Symptoms In A Male Dual-Diagnosis Outpatient Treatment, Brittney Tamayo Apr 2011

Improvement Of Trauma Symptoms In A Male Dual-Diagnosis Outpatient Treatment, Brittney Tamayo

Undergraduate Student Symposium

Traditionally, treatment aimed at helping those with both trauma related symptoms and substance abuse issues has first addressed the substance-related issues and then, after the client obtains abstinence, provided treatment to address the trauma-related issues. A more recent trend, the ‘traumaddiction’ model, suggests that psychological trauma and substance abuse can and should be treated concurrently. Support for this simultaneous treatment model has largely been limited to research in residential treatment settings. The current study set out to determine whether the integration of therapy for both trauma and substance abuse can be effective in an outpatient treatment setting as well. Specifically, …


Electrophysiological And Neuropsychological Correlates Of Emotion Regulation, Anita Singh Apr 2011

Electrophysiological And Neuropsychological Correlates Of Emotion Regulation, Anita Singh

Undergraduate Student Symposium

Avoidance or escape from emotionally negative events is associated with poor psychological health outcomes. Importantly, humans can influence how emotions are experienced or expressed through emotion regulation (ER) strategies. ER strategies have been shown to alter the expression of emotions in individual with differing levels of experiential avoidance (as indexed by the Acceptance and Action Questionnaire, or AAQ). Here, we are comparing a control group of participants who do not show emotional avoidance with a group of participants who score high on emotional avoidance. To that end, we are assessing neurophysiological and behavioral responses to emotional vs. non emotional pictures …


Complete Protection And Glycosylation Of Hydroxylysine, Lindsey Nowland, Stephanie Cirillo Apr 2011

Complete Protection And Glycosylation Of Hydroxylysine, Lindsey Nowland, Stephanie Cirillo

Undergraduate Student Symposium

One of the most common types of cardiovascular disease is the coronary heart disease, atherosclerosis. Adiponectin, a protein hormone, has been shown to play a role in preventing the development of atherosclerosis. Modification of this compound could help to produce more beneficial effects. One of the amino acids in adiponectin, Hydroxylysine (HYL), can often undergo posttranslational modifications, such as glycosylation.

The aim of the intended research is to protect specific functional groups of the amino acid to make it suitable for peptide synthesis. Total synthetic route will entail a differential protection of the amino acid, and addition of specific sugar …


Change And Stop-Signal Paradigms With Hands And Feet, Terrence Singh Apr 2011

Change And Stop-Signal Paradigms With Hands And Feet, Terrence Singh

Undergraduate Student Symposium

Hands and feet are useful in most sports but they are even more important when driving. The present study aims to find the time it takes to stop or switch a hand or foot movement. Researchers have noted that it takes longer to stop a hand than it does an eye, but little if any research has been done on foot movement. We are currently collecting data in the stop-signal paradigm in which subjects are to strike one of two keys when they see the corresponding visual stimulus unless an auditory signal is presented. Data are also being collected on …

Total Synthesis Of Functionalized Acenes, Sose Tokatlian

Undergraduate Student Symposium

This research project is focused on the total synthesis of three different acene dinitriles. With the understanding that syntheses of such acenes are affected by chemoselectivity, it is imperative that proper protocol be followed in order to produce the desired acenes in a favorable and useful yield. By means of Wittig reactions, condensation and reduction reactions the final product will be formed. Acene-2,3- dicarbaldehyde is utilized as a starting compound undergoing a Witting reaction and a consecutive Aldol reaction to produce a second ring with diester functionalities. Following reduction to a dialdehyde a modified Wittig reaction and consecutive Aldol reaction …


The Influence Of Emotional Regulation On Response Inhibition, Alexandra Srour Apr 2011

The Influence Of Emotional Regulation On Response Inhibition, Alexandra Srour

Undergraduate Student Symposium

The relationship between emotional regulation and response inhibition is examined. The presentation of highly arousing emotional pictures interferes with ongoing cognitive processes such as one’s ability to inhibit an unwanted response. In study 1, we measured emotional regulation and response inhibition independently. Results indicated that low emotional regulators exhibited faster reaction times. However, we did not find a correlation between emotional regulation and response inhibition. In study 2, we will examine the collective influences of emotional regulation and response inhibition. Participants will be trained to either up-regulate or down-regulate their emotional reactivity to highly-arousing negative stimuli. We predict that participants …


Kazal Serine Protease Inhibitors And Their Role In Prototheca Wickerhamii Pathogenicity, Norberto Mancera Apr 2011

Kazal Serine Protease Inhibitors And Their Role In Prototheca Wickerhamii Pathogenicity, Norberto Mancera

Undergraduate Student Symposium

Several genes are known to be involved in pathogenic processes. Among these, Kazal serine protease inhibitors (InterPro IPR002350) have been shown to be recurrently used by pathogenic eukaryotes. Kazal serine protease inhibitors are involved in the pathogenicity of Plasmodium falciparum by providing protection to parasitic proteins from the host’s defenses. Although Kazal protease inhibitors have been associated with the pathogenicity of several eukaryotic microbes, it is unclear if they are involved in Prototheca wickerhamii infection. Prototheca wickerhamii is an achlorophyllic green alga known to cause infections in humans. Olecranon bursitis, cutaneous, and bilateral choroiditis are three types of clinical infections …

Undergraduate Student Symposium

Natural products of fruits and vegetables play important roles in human health. Due to their benefits, researchers have tried to identify specific natural compounds within a single fruit or vegetable. These are technically demanding experiments because of the complex sample matrix and the need for a sensitive chemical analysis technique. This research project presents optimized protocols for the organic extraction and separation of multiple natural products of fruits and vegetables. The compounds were analyzed, and characterized by using Gas Chromatography-Mass Spectrometry and cross referenced with journal articles that have previously reported these products.


Exploring The Phylogeny Of Helicosporidium Using The Cyst Gene, Vanessa Anaya Apr 2011

Exploring The Phylogeny Of Helicosporidium Using The Cyst Gene, Vanessa Anaya

Undergraduate Student Symposium

Helicosporidium is a unique pathogen that can infect the larvae of mosquitoes. Phylogenetic analyses show promise of establishing a relationship between Helicosporidium and other species. Observation of species from the Aunexochlorella and Prototheca genera will provide an exact taxonomic classification and assist with identifying the closest relative to the genus Helicosporidium. Since it has been shown that the Helicosporidium shows effects on the larvae of mosquitos, this can be a potential organism of interest in the use as an alternative to common chemical insecticides. The confirmation of the relationship was found by performing sequencing of the ribosomal DNA of …


Event Related Potentials As A Measure Of Neural Inhibition Resulting From Bilingualism, Alicia Harnisch, Daniela Padron Apr 2011

Event Related Potentials As A Measure Of Neural Inhibition Resulting From Bilingualism, Alicia Harnisch, Daniela Padron

Undergraduate Student Symposium

Research suggests that there is a link between bilingualism and neural inhibition. Findings reveal that bilinguals more efficiently and effectively switch between cognitive tasks and ignore irrelevant aspects of a stimulus than monolinguals. According to the Inhibitory Control model of bilingualism, a mechanism is in place which allows bilinguals to suppress one language while using the other. This mechanism also mediates non-linguistic inhibition, which allows bilinguals to outperform monolinguals on these tasks. Functional Magnetic Resonance Imaging studies comparing monolinguals and bilinguals on non-language tasks suggest that these two groups utilize different frontal lobe areas when performing non-language cognitive tasks. The …


Effects Of Daxx And Il-8 Gene Expression On Tumor Growth, Sakthi Murugan, Ryan Smith Apr 2011

Effects Of Daxx And Il-8 Gene Expression On Tumor Growth, Sakthi Murugan, Ryan Smith

Undergraduate Student Symposium

Vascular Endothelial Growth Factor (VEGF) is an important factor that regulates tumor cell growth and angiogenesis. Tumor angiogenesis results in the supply of oxygen and nutrients to the tumor cells, enabling further growth. Various genes in the genetic sequence contribute differently, and affect this process by either promoting or inhibiting further angiogenesis. Among these genes are DAXX and IL-8. DAXX gene, which encodes Death Domain Associated protein, can enhance FAS mediated apoptosis, by activating the Jun N-Terminal Kinase (JNK). MDM2 is an oncogenic protein, that is believed to ubiquinate DAXX and reduce its level when it is overly expressed; HAUSP …

Artscience: A Study Of The Human Arterial And Venous Systems, Nergess Taheri

Undergraduate Student Symposium

Artscience is a blending of both aesthetic and scientific methods. This project combines both in a way that neither can be distinguished from the other. This is a study of the human arterial and venous systems. These systems were artistically represented as linoleum block prints. Two models were produced, one for the arterial system and the other for the venous system. The process used to make the models is called printmaking. Printmaking was one of the first forms of mass illustration with each print being considered an original. In this study two linoleum blocks were carved into the desired anatomical …


Analyzing Hotel Room Cleanliness On A Microscopic Level, Ahmad Khalid, Kodi Stevens Apr 2011

Analyzing Hotel Room Cleanliness On A Microscopic Level, Ahmad Khalid, Kodi Stevens

Undergraduate Student Symposium

The cost of a hotel room is usually correlated to the quality of the hotel room and the quality of services provided during one’s stay; e.g. the cleanliness of the room and the thoroughness of the cleaning staff. The cleaner a hotel is the more desirable it is. The goal of this experiment was to analyze hotel cleanliness at the microscopic level to determine if pathogenic micro-organisms were present. Samples were taken from telephones, toilet seats, remotes, toilet flushers, bath tubs and doorknobs from five different hotels and grown at room temperature on nutrient agar plates, counted and then isolated. …

GC-MS is a powerful analytical instrumentation tool capable of detecting, identifying and quantifying many volatile organic compounds. The GC-MS technique is routinely used in chemistry research and manufacturing laboratories. Despite its wide application in organic chemistry and ease of use, many colleges …


The Impact Of Speed Reading On The Generation Of Inferences, Anil Sawh Apr 2011

The Impact Of Speed Reading On The Generation Of Inferences, Anil Sawh

Undergraduate Student Symposium

This experiment explores the effect that speed-reading has on the inferences made while reading texts. More specifically it will compare comprehension and inferences made between participants that read at a normal rate and participants that have been trained to read at a faster rate than normal. Speed-reading courses promise the ability to learn how to take in larger amounts of text and information than normal reading. However, most research has shown that while these courses increase reading speed, comprehension and retention of the material suffers a significant drop (Just, Carpenter, & Masson, 1986). Very little research has examined the effects …


The Effects Of Categorization On Memory, Logan Armstrong Apr 2011

The Effects Of Categorization On Memory, Logan Armstrong

Undergraduate Student Symposium

The purpose of this study was to explore the effects of categorization on our ability to remember events and objects. This is an important question because little research has tested the notion that the ability to categorize helps produce better memory. Morris & Baker-Ward (2007) studied a similar question when they examined whether having the vocabulary to describe an experience affected the ability to remember that experience. Specifically, they tested whether infants who had learned their colors prior to participating in an experiment involving different colored bubbles would recall the experiment better than those who learned the colors after the …

Carpentier’S Version Of Time: Back To The Ending, Genevieve Macaisa Apr 2011

Carpentier’S Version Of Time: Back To The Ending, Genevieve Macaisa

Undergraduate Student Symposium

In Alejo Carpentier’s short story “Journey Back to the Source,” he used a nonlinear narrative and manipulated temporal elements to challenge the traditional view of the passage of time. Through his experimentation, he developed a new form of the narrative timeline. Carpentier’s work demonstrates that time can move in reverse, from the end to the beginning, while still moving forward. The theories of Sergei Eisenstein and Henri Bergson influenced Carpentier’s experiment and reveal the magnitude of his pushing of the boundaries. For instance, Carpentier employs a narrative strategy like Eisenstein’s cinematic montage to stitch together a timeline. Bergson’s theories of …


More Than Just A Memory, Sebastian Acosta-Nijamkin Apr 2011

More Than Just A Memory, Sebastian Acosta-Nijamkin

Undergraduate Student Symposium

“More than just a memory” is a film about love and friendship. Ethan is confronted with a tough decision: whether to tell the girl he loves how he really feels, or whether to accept the fact that she loves someone else and that Ethan will only be a friend in her eyes. Throughout the film, Ethan is driving in a car, and flashbacks of the night where he chose to be just a friend keep entering his mind. That night he made a choice -- a choice that would change his life forever. The film is directed by Sebastian Acosta-Nijamkin.


The Widening Spectrum Of Celiac Disease, Mary-Catherine Fleck Apr 2011

The Widening Spectrum Of Celiac Disease, Mary-Catherine Fleck

Undergraduate Student Symposium

Celiac Disease or Celiac Sprue is a chronic autoimmune disorder with a genetic component. Gluten or gliadin is a protein found in wheat, rye and barley. Ingestion by genetically susceptible individuals, under certain conditions such as surgery, infection, or severe emotional stress can trigger the onset of Celiac Disease, the production of anti-gliadin antibodies, which destroy the villi lining the lower intestines. This is where most of the nutrients for sustenance are absorbed and hence can lead to malnutrition, diarrhea, anemia and fatigue; the villi gradually get restored, only upon exclusion of gluten from the diet. What was once only …

The Effects Of Sugar Substitutes On Gene Expression In Saccharomyces Cerevisiae, Hannah Bromberg Apr 2011

The Effects Of Sugar Substitutes On Gene Expression In Saccharomyces Cerevisiae, Hannah Bromberg

Undergraduate Student Symposium

Sugar substitutes are marketed as being healthier than sucrose (table sugar). Within this experiment, information about how table sugar and three different sugar substitutes, Splenda (sucralose-based), Truvia (stevia-based), and Equal (aspartame-based), affect gene expression in yeast was examined. Since the genomes of yeast and humans are approximately 30% similar, the specific genes selected for analysis in yeast overlapped with genes that are expressed in humans. Thus, Saccharomyces cerevisiae (Baker’s yeast) was used as a model eukaryotic organism in order to examine the effects of sugar substitute exposure on gene expression. The yeast was grown under four different conditions: 1) A …

Crystalline Metal-Organic Frameworks Drug Transfer, James M. Brandes Apr 2011

Crystalline Metal-Organic Frameworks Drug Transfer, James M. Brandes

Undergraduate Student Symposium

A relatively new type of chemical compound is finding application in such areas as gas storage, and drug delivery. Metal-organic frameworks, or MOF’s, are rigid structures with large cavities which other molecules can occupy for later release and use. We are studying the properties of new MOF’s based on copper and organic molecules known as BAII’s. In at least one case it has been demonstrated that these frameworks are capable of adsorbing, and later desorbing, host molecules. This makes them candidates for drug delivery and gas storage. The synthesis, characterization and adsorption properties of one framework will be discussed. A …

Nonlinear Analysis Of Phosphorus Levels In Lake Okeechobee And Proposals Of Solutions, Lacrima Nemulescu Apr 2011

Nonlinear Analysis Of Phosphorus Levels In Lake Okeechobee And Proposals Of Solutions, Lacrima Nemulescu

Undergraduate Student Symposium

The research was designed to analyze the phosphorus levels in Lake Okeechobee and the consequences related to the introduction of supplemental nutrients in an oligotrophic ecosystem. The eutrophication of a fresh water habitat has the potential of negatively impacting the underwater species, as well as the predators that depend on these organisms to obtain their nutrition. An increase in the amount of phosphorus has portrayed a positive correlation with the stimulation of plant growth. The most detrimental consequences are associated to algal overgrowth, which causes the oxygen levels inside the water to decrease and therefore deplete the sub aquatic environment …
