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 …

Peace Through Hostility: The Beats' Call For Equality Through Aggressive Poetic Imagery, Dan Abella Apr 2011

Peace Through Hostility: The Beats' Call For Equality Through Aggressive Poetic Imagery, Dan Abella

Undergraduate Student Symposium

This paper focuses on the poetic techniques of two Beat poets, Lenore Kandel and Allen Ginsberg, whose impressionistic, caustic poetry is in some ways representative of the entire Beat movement. Kandel's poems ring with overt sexual overtones, seemingly unconcerned with respect to morality or grace, invoking instead shocking and disturbing images. In her poetry is an intrepid protest of violence and conformity through the paradoxical use of violent description. Like the other Beat poets, she often refused to compromise in either structure or content, adopting a flowing, free-verse form. Allen Ginsberg's poetry employs the same modes: free verse, shocking context, …

Myh16 Masticatory Gene Mutation Correlates With The Evolution Of Human Morphological Cranial Capacity, Renee Michelle Potens Apr 2011

Myh16 Masticatory Gene Mutation Correlates With The Evolution Of Human Morphological Cranial Capacity, Renee Michelle Potens

Undergraduate Student Symposium

In the late Miocene, Homo sapiens encephalization accelerated simultaneously with an anatomic craniofacial transformation, associated with a shift towards a gracilization pattern of diet. Hansell H. Stedman has discovered a deleterious masticatory gene mutation responsible for jaw muscle development that is found in all modern human populations. This gene is functionally conserved in all non-human primates such as chimpanzees and extinct Hominidae species such as Australopithecus and Paranthropus, and is only found in its mutated, non-functional state in humans. The myosin heavy chain (MYH16) inactivation occurred after the divergence of the phylogenic lineages leading to humans and …

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 …

The Occurrence Of Helicosporidium In Freshwater Bodies In South Florida, Jhanelle Dawes Apr 2011

The Occurrence Of Helicosporidium In Freshwater Bodies In South Florida, Jhanelle Dawes

Undergraduate Student Symposium

Helicosporidium is a mosquito pathogen found in most South Florida water ecosystems. It is composed of four cells and related to green algae but is non- photosynthetic. It has been proven to be a vector control agent and has therefore shown the potential to eradicate mosquito-borne diseases. However, barely any biogeographical and ecological data regarding Helicosporidium exists. In order to determine the occurrence of Helicosporidium in environmental freshwater samples, water samples were collected from a local south Florida natural freshwater body. The metagenomic DNA extraction and specific amplification of Helicosporidium 18S rDNA genes using Polymerase Chain Reaction were then performed …

The Influence Of Emotional Stimuli On Attention Sharing In A Dual Modality Erp Paradigm: Effects Of Varying Interstimulus Intervals, Amanda Lynch Apr 2011

The Influence Of Emotional Stimuli On Attention Sharing In A Dual Modality Erp Paradigm: Effects Of Varying Interstimulus Intervals, Amanda Lynch

Undergraduate Student Symposium

A large and growing body of evidence demonstrates that attention is preferentially allocated to stimuli with emotional content. Emotionally negative stimuli serve as a mechanism of biological preparedness to enhance attention. In agreement with this idea, previous studies looking at the influence of emotional pictures on tone processing showed that the ERP measures of cognition was reduced when participants were exposed to an emotional picture with intermittent auditory startle probes We hypothesized that if an auditory oddball (attention capturing) stimulus was placed in the same perceptual time frame as a preceding emotional picture, the auditory stimulus would then share attention …

The Real Within The Dream, Jessica Furth, Christopher Garcia, Natasha Matijasevic Apr 2011

The Real Within The Dream, Jessica Furth, Christopher Garcia, Natasha Matijasevic

Undergraduate Student Symposium

Latin American modernist authors were inspired by European surrealists to craft their own experimental style, magical realism. In his short story, “The Night Face Up” ("La Noche Boca Arriba"), Argentine author Julio Cortázar employs magical realism to alter the reader’s perception of the “real” and the “dream” world. The story opens with an unnamed protagonist who gets into a motorcycle accident. The remainder of the story alternates between scenes from his hospital bed and scenes from a presumed dream, where he is a Motecan warrior running from the Aztecs. The reader is expected to believe that the hospital scene constitutes …

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 …

Investigation Of A Crime Scene: Applying Biological And Chemical Forensic Techniques, Jennifer Marcelin, Jorge Leal, Sagir Patel, Lindsey Nowland

Undergraduate Student Symposium

The purpose of this experiment was to explore the principles of investigating a crime scene; utilizing both biological and chemical laboratory techniques. Collecting proper evidence is crucial to crime scene investigation. The insight that an investigator may gain about a perpetrator can be determined by analyzing the physical evidence obtained at the scene, and therefore an investigator must carefully examine numerous pieces of evidence found at a crime scene. However, the knowledge and education of the investigator are able to elucidate both the obvious and the obscure. Each piece of evidence may provide a clue to who committed the crime …

Independence From The Operating System, Thomas Sylvester Apr 2011

Independence From The Operating System, Thomas Sylvester

Undergraduate Student Symposium

Virtualization is almost as old as mainframe computers, when a large computer was shared by several different users. Computer engineers have also struggled with many different Operating Systems (OS) that traditionally worked on specialized hardware. Usually only one OS could be loaded on one physical machine at one time. This posed a significant barrier to experimentation and testing of multi-OS environments.

These VMs can relieve instructors and students of the configuration issues across different physical machines; every class's VM can be loaded the same way. These VMs have additional benefits. Dedicated VMs can be created to address OS, software and …

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, …

Expression Of At1, At2 Receptors And A Non-At1, Non-At2 Angiotensin Ii Binding Site In Rat Brain After Endothelin-1 Induced Ischemic Stroke, Luz Gonzalez Reiley, Aisha Haniff Apr 2011

Expression Of At1, At2 Receptors And A Non-At1, Non-At2 Angiotensin Ii Binding Site In Rat Brain After Endothelin-1 Induced Ischemic Stroke, Luz Gonzalez Reiley, Aisha Haniff

Undergraduate Student Symposium

New findings suggest that the activation AT1 receptor decreases cerebral perfusion after an ischemic stroke in the brain while the activation of AT2 receptor opposes those actions providing neuroprotective effects. Recent discoveries reveal the existence of a novel non-AT1, non-AT2 binding site for angiotensin II (Ang II) in the brain which may indicate additional effects of the brain angiotensin system after ischemic damage. To assess this, 5 rats were microinjected with 3 μM of 80 μM endothelin-1 (ET-1) to stimulate middle cerebral artery occlusion in the right hemisphere of the forebrain. 24 hours later, the rats were sacrificed and the …

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 …

Experimental And Numerical Determination Of Phase Synchronization Between A Chua System And An External Periodic Signal, Yaneve Shemesh Apr 2011

Experimental And Numerical Determination Of Phase Synchronization Between A Chua System And An External Periodic Signal, Yaneve Shemesh

Undergraduate Student Symposium

We present our first experimental results in relation to the phase synchronization of a single sinusoidal function to a Chua oscillator. We approached the synchronization process with real time observation. We were able to observe that a Chua oscillator will stay phase synchronized if the periodic signal has the appropriate amplitude and frequency, i.e., falls inside a synchronization tongue (Arnold Tongue). These early results will be compared in the future with numerical simulations.

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 …

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 …

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 …

Bystanders To Evil: The Failure Of The United States’ Foreign Policy Towards Genocide, Anam Ismail Apr 2011

Bystanders To Evil: The Failure Of The United States’ Foreign Policy Towards Genocide, Anam Ismail

Undergraduate Student Symposium

Since the Armenian Genocide in the early twentieth century, the United States’ policy towards genocide has been, at best, delayed and, at worst, intentionally indifferent. This study will examine America’s historic reaction to genocide, as well as the radically different results that might have been achieved with even minimal efforts. To understand American action, research will focus on four examples of mass killing: the extermination of Jews and other undesirables by Nazi Germany, the widespread ethnic cleansing of Bosnian Muslims by Serbian nationalists, the conflict between rivaling Hutus and Tutsis in Rwanda, and the ongoing war plaguing Southern Sudan. The …
