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 …

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 …

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 …

Implicit Bias And Public Policy Recommendations, Alyssa Mineo Apr 2011

Implicit Bias And Public Policy Recommendations, Alyssa Mineo

Undergraduate Student Symposium

We intend to measure implicit (as opposed to self-reported) attitudes towards gay people, specifically in the context of adoption rights. Opponents of gay adoption rights persist in arguing that having gay parents is harmful to the children and for this reason should be opposed. However, if the position is based exclusively on concern for the welfare of the children rather than (entirely or partially) on the parents’ sexual orientation per se, it should follow that any individual who acts out of this concern would be equally concerned with the welfare of the children adopted by heterosexual parents. Whatever restrictions …

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 …

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 …

Cognitive Inhibition In Bilinguals Vs. Monolinguals, Juliana Acosta, Raquel Chocron, Jacqueline Pablos Apr 2011

Cognitive Inhibition In Bilinguals Vs. Monolinguals, Juliana Acosta, Raquel Chocron, Jacqueline Pablos

Undergraduate Student Symposium

Bilingualism has been linked to enhanced cognitive abilities and these enhanced abilities are believed to be mediated by the same frontal lobe system that controls language output in bilinguals. Moreover, recent research suggests that this bilingual advantage may be moderated by degree of balance between the two languages such that those who are equally proficient in their two languages show the best performance on cognitive tasks compared to unbalanced bilinguals and monolinguals. For instance, results from one study revealed that balanced bilinguals showed significantly fewer errors on the Wisconsin Card Sorting Test (WCST) than unbalanced bilinguals. Thus, the purpose of …

Chemical Interactions Between Staphylococcus Aureus And Candida Albicans Within Mixed Species Biofilms, Rachel Comito, Fiorella Diaz, Martin Herrera, Ariel Jordan Apr 2011

Chemical Interactions Between Staphylococcus Aureus And Candida Albicans Within Mixed Species Biofilms, Rachel Comito, Fiorella Diaz, Martin Herrera, Ariel Jordan

Undergraduate Student Symposium

Biofilms are communities of microbes that grow and function together in order to gain protection from environmental stressors. Staphylococcus aureus and Candida albicans are two of the most common microbes found to grow as biofilms within medical facilities and are among the leading causes of infectious disease. Previous studies found that S. aureus and C. albicans grow together synergistically within biofilms and that S. aureus actually secretes some chemical that drastically improves candidal biofilm growth. The current project is focused on better characterizing the mechanism of this chemical interaction. One aspect of the project examines when S. aureus secretes this …

A Cardiac Arrhythmogenesis Model: Spiraling Out Of Control, Rajeswari Murugan Apr 2011

A Cardiac Arrhythmogenesis Model: Spiraling Out Of Control, Rajeswari Murugan

Undergraduate Student Symposium

Arrhythmic Sudden Cardiac death accounts for up to 5 million cases per year across the world. Cardiac arrhythmia is an abnormal activity in the heart that can lead to sudden cardiac death resulting from ventricular fibrillation. The electrocardiogram (ECG) reading during an arrhythmia indicates rapid contractions of the heart. This phenomenon is due to the development of a re-entrant circuit of electrical activity that repetitively stimulates the heart. The heart presents a spatio-temporal complex system, where the tissue biophysics and structure leads to reaction diffusion type models. These models portray the re-entrant wave patterns observed during arrhythmia. Fibrillation is characterized …
