Aids: An African Epidemic, Christina Bethea Mar 2007

Aids: An African Epidemic, Christina Bethea

Undergraduate Student Symposium

Every year in Africa, millions of adults and children are infected with AIDS. This disease is the number one killer in Africa, even outweighing malaria. AIDS has infected over 39 million Africans in total. Additionally, despite the fact that it holds only 10 percent of the population, 90 percent of the world’s AIDS orphans are on this continent. Obviously, this disease threatens the African life expectancy, dropping it from 66 to 33 years of age. It cuts off workers in their prime, thus affecting many of Africa’s businesses and making Sub-Saharan Africa’s GDP suffer. Unfortunately, if the African market suffers …

The Role Of Chaperones In Prion Infection, Prerna Alfa Thomas Mar 2007

The Role Of Chaperones In Prion Infection, Prerna Alfa Thomas

Undergraduate Student Symposium

Prions are infectious proteins that cause neurodegenerative diseases called transmissible spongiform encephalopathy which affect several species, including humans. Chaperones are molecules that bind to the nascent peptide chain and fold the polypeptide chain into its secondary or tertiary structure. Prions affect the protein folding machinery or molecular chaperones of the cell which might lead to the formation of aggregates. The goal of this literature review is to highlight several functions of chaperones in prion infection, to draw attention that prions could be misfolded molecular chaperones, and to indicate the therapeutic applications of chaperones in prion infection.

Chaperones may perform a …

The Ballerina In The Box, Amy Harvey Mar 2007

The Ballerina In The Box, Amy Harvey

Undergraduate Student Symposium

When read for the first time, this poem seems to be about one of those beautiful little jewelry boxes little girls receive as a gift from a loved one; the kind that have a spinning plastic ballerina in them. However, at second glance the reader might notice that it is actually about the insecurities of being alone. This poem is an allegory of an experience of its author.

The American Dream: Support The Dream Act, Myra Rafi Mar 2007

The American Dream: Support The Dream Act, Myra Rafi

Undergraduate Student Symposium

Every day, many young and eager students face barriers to obtaining a college education. They are prohibited from working, driving, and applying for the financial assistance that so many other young, soon-to-be college students can have. Unfortunately, this is the life many undocumented students lead. After graduating from high school, these students have no options for working toward the futures they have dreamt of. However, there is an option, a prospect that may help them to achieve their dreams: it is the Development Relief Education for Alien Minors Act: the DREAM Act. This bipartisan legislation was proposed by no less …

Seeing It Through: An Overview Of Retinal Degeneration And Future Treatments, Michael Au Mar 2007

Seeing It Through: An Overview Of Retinal Degeneration And Future Treatments, Michael Au

Undergraduate Student Symposium

Degenerative retinal diseases are, to date, largely untreatable – a shortcoming born of the complexity of the nervous system and our finite understanding. Retinitis pigmentosa (a group of inherited eye disease of the retina) scuttles about the family tree relatively unchecked, slowly and silently impairing vision in 1.5 million people worldwide. Comparatively, macular degeneration, an age-related kin of retinitis pigmentosa, afflicts sufferers on a magnitude of roughly 20 diagnoses per hour within the United States alone. Such degenerative diseases almost always culminate in the death of rod and cone photoreceptor cells along with the accompanying loss of visual capacity. This …

Synthesis Of New Ruthenium (Ii) Complex With A Long Excited State Lifetime For Its Use As A Dna Probing Biosensor, Terry-Ann Dawes Mar 2007

Synthesis Of New Ruthenium (Ii) Complex With A Long Excited State Lifetime For Its Use As A Dna Probing Biosensor, Terry-Ann Dawes

Undergraduate Student Symposium

Due to the degree of instrumentation needed for DNA diagnostic and colorimetric procedures, it has become considerably expensive for the public and independent laboratories to conduct research on genetic diseases and to probe DNA. Even though myriad technologies are available for detection and measurement of modified target molecules, cell and DNA probing techniques are involved and complex processes. Current methods of chemiluminescence by metal-ligand complexes (such as those with ruthenium) have proven to be ineffective because luminescent lifetimes are extremely short. Hence, the primary focus of this research is to synthesize novel ruthenium-ligand complexes that will have enhanced emission lifetimes. …

Recovery Of Branching Coral In Devil’S Crown, Galapagos Islands, Following El Niño Impacts, Kristen Taylor Mar 2007

Recovery Of Branching Coral In Devil’S Crown, Galapagos Islands, Following El Niño Impacts, Kristen Taylor

Undergraduate Student Symposium

In 1982-83 a severe El Niño-Southern Oscillation (ENSO) event killed 95% of the scleractinian coral in the Galapagos Islands, Ecuador, with over 99% coral mortality reported at the study site, Devil’s Crown. Also at this site, a reef composed primarily of the branching coral Pocillopora spp. was lost from primary and secondary biological disturbances associated with ENSO. For the subsequent 11 years Pocillopora was not observed there, however 5 colonies were seen in May, 1995. The number and size of colonies was monitored from 1995-2004. Projected surface areas were determined using two methods: direct measure during snorkel surveys using a …

Potential Materials For Hydrogen Storage. Synthesis Of Building Blocks For New Metal – Organic Frameworks, Nadia Rampersaud Mar 2007

Potential Materials For Hydrogen Storage. Synthesis Of Building Blocks For New Metal – Organic Frameworks, Nadia Rampersaud

Undergraduate Student Symposium

As reserves of fossil fuel become depleted the need for alternative sources of energy grow increasingly more important. The use of hydrogen gas as a fuel is one potential alternative energy source. However gases such as hydrogen are difficult to store and transport because even small amounts require a proportionately large amount of space. One way to combat this problem may be to create porous materials which may absorb large quantities of gas for storage in a much smaller space. MOF (metal-organic- framework) compounds have been demonstrated to have great potential as candidates for gas storage. MOF compounds are composed …

Mythmaking, National Identity And Balkan History, Tajhira Omphroy Mar 2007

Mythmaking, National Identity And Balkan History, Tajhira Omphroy

Undergraduate Student Symposium

The Balkans, a region seen as “the powder keg of Europe” since the 17th century, is a complex labyrinth of nationalism, ethnicity and religion. Balkan history is best explained in terms of the myths that are the foundation of both religious and nationalistic fervor for the various Balkan ethnic groups. The protagonists of these myths have become not only national heroes, but also saints of the Orthodox Church. In this way, the mythology of each Balkan nation or ethnic group envelops both nationalistic pride and religious beliefs, the result of which is a powder keg that frequently explodes.

Stress Is Related To Sleepiness In Nsu Undergraduate Students, Lara Murphy, Maureen Green Mar 2007

Stress Is Related To Sleepiness In Nsu Undergraduate Students, Lara Murphy, Maureen Green

Undergraduate Student Symposium

College students often suffer from chronic sleep restriction and up to one third of college age adults suffer from excessive daytime sleepiness (EDS). The finding that high numbers of college students experience EDS is very problematic as this is a population that uniquely requires optimal cognitive functioning to successfully complete course material. One possible cause of EDS from chronic sleep restriction in college students is the high levels of stress experienced by this population. In fact, changes in the stress- related hormone, cortisol, have been previously shown to greatly affect sleep in clinical populations. Here, we hypothesized that subjective levels …

Molecular Chaperones And Parasites, Andrew Deonarine Mar 2007

Molecular Chaperones And Parasites, Andrew Deonarine

Undergraduate Student Symposium

Molecular chaperones and chaperonins are proteins found in all living organisms from the prokaryotic bacteria all the way to the eukaryotic human. These proteins serve to play several important roles within the cell. The tasks vary from assisting directly or indirectly in the folding of nascent proteins produced by the ribosome, repairing heat damaged proteins, involvement in cell signaling, and cell differentiation. Many of these proteins are inducible in response to heat. Therefore they became known as heat shock proteins (Hsp). Proteins are absolutely vital in any cell. They serve specific structural and functional roles to enable cellular life. Currently, …

Using Microarray Technology To Examine The Effects Of Zinc On Gene Expression In Saccharomyces Cerevisiae: A Proposal, Quratulain Hayat Mar 2007

Using Microarray Technology To Examine The Effects Of Zinc On Gene Expression In Saccharomyces Cerevisiae: A Proposal, Quratulain Hayat

Undergraduate Student Symposium

Zinc is one of the principle trace elements required in biological systems, with structural or enzymatical roles in hundreds of proteins. In humans, zinc deficiency has gradually come to be recognized as a clinically significant and common form of malnutrition, particularly in chronically ill patients. The clinical manifestations of zinc deficiency are diverse with effects on the immune system, appetite, and embryonic development. The regulation of zinc distribution remains a critical, unanswered question. The manner in which zinc is released from its tight binding sites in proteins and its transfer from one site to another are also unknown. While several …

Detecting Deception From Thin Slice Communications, Carla Perna, Alisha Van Hoose Mar 2007

Detecting Deception From Thin Slice Communications, Carla Perna, Alisha Van Hoose

Undergraduate Student Symposium

Research suggests that people are not very skilled at detecting deception from ordinary communications (Vrij, 2000). A recent meta-analysis (Bond & DePaulo, 2006) indicated that the average accuracy in discriminating a truthful from a deceptive statement was 54%, when chance is 50%. Another line of research has shown that people are able to make remarkably accurate inferences from very brief exposures (or “thin slices”) of nonverbal behavior (Ambady & Rosenthal, 1993; Willis & Todorov, 2006). We propose that the ability to detect deception may actually be greater when people observe thin slices communications rather than longer communications. In a within- …

Cranberries: The Use Of A Naturally Occurring Compound To Fight Against Periodontopathogens, Debbie L. Darius Mar 2007

Cranberries: The Use Of A Naturally Occurring Compound To Fight Against Periodontopathogens, Debbie L. Darius

Undergraduate Student Symposium

This literature review focuses on the use of a naturally occurring compound found in cranberries (proanthocyanidins) to fight against periodontopathogens and thus the development of periodontal disease. Periodontopathogens and their invasion in gingival tissues and periodontium is the usual cause of periodontitis. Oral microorganisms coaggregate to become major bacterial complexes, allowing their proteases to digest similar components of the gingival crevicular fluid located in subgingival sites. The most common microbe associated with this disease is P. gingivalis where its proteolytic enzymes gingipains and dipeptidyl peptidases IV break down collagen and create large supplements of iron for the bacteria. However, recent …

Third-Wave Feminism In Legally Blonde, Lauren Butler Mar 2007

Third-Wave Feminism In Legally Blonde, Lauren Butler

Undergraduate Student Symposium

Both Amanda Brown’s novel, Legally Blonde, and the film version based on her chick-lit book, emphasize key elements of feminism and seek to empower women. Legally Blonde exemplifies the “strand” of feminism known as the “third-wave” (Dole 87). Third wave feminists seek to reclaim their femininity, and as Carol M. Dole put it, “reclaim pink” (89). The film and novel portray the epitome of a true third-wave feminist, Elle Woods (Reese Witherspoon). She is a woman who proudly flashes her girlie appearance, refuses to conform to society’s expectations of women, achieves greatness though her determination and diligence, and celebrates …

The Arguments Of Abortion: An Analysis, Michael Bergbauer Mar 2007

The Arguments Of Abortion: An Analysis, Michael Bergbauer

Undergraduate Student Symposium

Since 1973, with the decision to legalize abortion in the landmark case of Roe v. Wade, America has hotly contested the question: Should abortion be legal practice? The debate of this question has spawned controversy, violence, and political concern. Although a majority of people agrees that abortion should be permissible in some cases – such as in situations when the mother is a victim of rape or incest, or if an abortion would be of extreme benefit to the mother’s health – the issue divides vastly on the use of abortion for any other reason. With the debate having raged …

Comparing Nuclear Fission And Nuclear Fusion As An Alternative Source Of Energy, Natasha Antonovich, Michael Ratliff, Neeketa Sheth Mar 2007

Comparing Nuclear Fission And Nuclear Fusion As An Alternative Source Of Energy, Natasha Antonovich, Michael Ratliff, Neeketa Sheth

Undergraduate Student Symposium

The purpose of this research project was to explore alternate nuclear energy sources. The nuclear energy sources that were examined were fission and fusion. From the research that was done, pros and cons were found for each type of nuclear energy. Fission, being an established technology for energy, posed an economical advantage; however, the waste that is given off from these reactions is a great environmental detriment. Fusion reactors are newer nuclear energy sources, thus they are more costly, but their lack of radioactive waste gives fusion an environmental advantage. Given that both reactions have positive and negative sides to …

Thank God For Aids: Persistent Stereotypes In U.S. Network Television, Micah Moreno Mar 2007

Thank God For Aids: Persistent Stereotypes In U.S. Network Television, Micah Moreno

Undergraduate Student Symposium

This paper explores the use of stereotypes to characterize homosexuals on network television in the United States. With a goal of raising reader awareness of network television’s over-reliance on stereotypes, I also argue that the stereotypical depictions of homosexuals on network television has negative and sometimes even dangerous ramifications in contemporary U.S. culture.

Many argue that the increasing number of gay and lesbian characters featured on network television is an indication of society’s emerging acceptance of homosexuality. However, this is a false assumption given that many of the shows cited as promoting equality are not meant to do that, but …
