Abstract

Kaolin geophagia is associated with the relief of gastrointestinal distress, but it may also cause adverse health effects on the body. This study was designed to: assess kaolin composition; test if 129SvEv mice would consume kaolin and determine the consequences of consumption; and assess rotational stress modulation of consumption. Thirteen kaolin samples were purchased from Alabama and Georgia stores. Chemical and physical properties were characterized for each sample using a Munsell chart, pH meter, Energy Dispersive Spectroscopy, Transmission Electron Microscopy, Visible Near-InfraRed Spectra, and Inductively Coupled Plasma-Optical Emission Spectrometry. Kaolin was then given to mice as food supplements and …

Generation And Assessment Of Muscular Mutations In Caenorhabditis Elegans, Katie N. Reget

DePaul Discoveries

A study of egg laying muscular mutations in C. elegans was conducted over a span of ten weeks. Parent (EGL-19) and wild type (N2) were exposed to mutagenesis and integration mutation techniques to generate genetic and physical different mutants. Overall, four genetic, physical and phenotypically unique worms were generated for the process of mutagenesis. The worms used in the process of integration were found to have shortened life spans, reduced size and decrease numbers of progeny.

Predictors Of Money Spent On Drugs In Substance Users, Simona Ciobotaru

DePaul Discoveries

Financial need is a major stressor for individuals who are reentering the community after substance abuse and/or incarceration. Family members and friends make up a great majority the support networks from which reentering people can receive financial support. However, that financial support could possibly contribute to drug use when the individual is actively using. The goal of this study was to further understand the implications of material and financial support specifically being transmitted from family members. This study looks at psychosocial predictors in relation to money spent on drugs in the last 30 days of 270 individuals entering substance abuse …

The Effect Of Hydrogen Peroxide On Leishmania Amazonensis Promastigotes, Debra Eluobaju

DePaul Discoveries

Leishmaniasis is a disease caused by the parasite Leishmania. The disease causes lesions to the skin and face; when visceral it becomes fatal to its host. Leishmanias are transmitted through the female blood-sucking sand fly into its mammalian host, where it infects macrophages. Within the macrophages, Leishmania differentiates from a motile, rod shaped, nonvirulent promastigotes to a non-motile, spherical shaped, virulent amastigotes. Differentiation is due to the high temperature of the mammalian host body, in addition to the low pH of the macrophage. In vitro, the cells are differentiated in Graces medium (pH 5.3) at 33◦C. I investigated whether …

Knowledge Of Clinical Measures And Healthcare Adherence In Young Gay And Bisexual Men Living With Hiv/Aids, Harry A. Persaud, Douglas Bruce

DePaul Discoveries

Knowledge of HIV/AIDS test results and adherence to healthcare interventions are two important outcomes that reflect proper HIV/AIDS management. This study aimed to determine which demographic and HIV acceptance measures were significantly associated with health literacy and adherence indicators in young MSM. 200 HIV/AIDS positive young MSM completed computer based surveys regarding demographics, HIV/AIDS health literacy indicators, and HIV/AIDS acceptance measures. It was found that young African American MSM, in comparison to young white MSM, had lower odds of knowing both viral load and CD4 measures; health literacy indicators. Further, participants who had a high school diploma were found to …

A High-Altitude Balloon Platform For Determining Regional Uptake Of Carbon Dioxide Over Agricultural Landscapes, Angela M. Bouche

DePaul Discoveries

Interactions between the biosphere and atmosphere are an important part of the global carbon cycle, and quantifying the carbon dioxide exchanges between them is helpful in predicting the uptake of carbon dioxide from anthropogenic sources by the biosphere in the future. In the Midwestern United States, agricultural systems cover a large part of the landscape, so understanding their role in influencing the global carbon budget is crucial as anthropogenic sources of carbon dioxide grow larger. Carbon dioxide exchanges can be measured by eddy covariance at the ecosystem level (bottom-up approach) or regionally by inversion techniques (top-down approach). Here we describe …

Diol-Mediated Versus Water-Mediated Proton Transfer Reactions, Angela Moses

DePaul Discoveries

The triple-proton-transfer reactions of 8H-1,8-naphthyridin-2-one (8H-naph) have been investigated by employing different ab initio quantum mechanical methods. The proton transfer reactions studied were facilitated through an adjacent 1,3-propanediol molecule or two adjacent water molecules. Identical proton transfer reactions were studied using a model system of 8H-naph to investigate the validity of computational approaches that use model systems to study more complex systems. The solvent effects on the structures were investigated for comparison to the initial gas phase calculations. The potential energy, reaction force, and work profiles were studied along the intrinsic reaction coordinate to monitor the developing proton transfer reactions.

Do Oaks With A Provenance Related To Warmer Climates Emit More Isoprene?, Elizabeth Carter

DePaul Discoveries

The hydrocarbon isoprene plays an important role in atmospheric chemistry, particularly in regards to air pollution and climate change. It is important to know why certain plant species emit isoprene and what factors affect its production in order to predict future air quality. Past research has indicated that isoprene aids in coping with heat stress, so it was hypothesized that source latitude (a proxy for climate) would significantly impact isoprene production by oaks grown in a common location. Twelve bur oaks collected from a latitudinal range (30-45˚) and raised at the Morton Arboretum were assayed for their isoprene emission rate …

Courtship In The Borderlands: Hollistic Intimate Space Creation Within Courtship Ideaologies, Alejandro Sánchez

The Compass

While telling me the story of how she met her husband, Mrs. Aguilar told me “I really feel bad for your generation, they are missing out on falling in love.” She was referring to the courtship practices, or the social regulation and cultural markers between two individuals who create a social relation developing a “relationship.”1 She was comparingthe courtship practices of her generation to that of mine and her statement is reflective of the changes in the cultural environment. From courting, a “relationship” can develop. Its dimensions are defined by the mediation between cultural norms and the agent, and can …

Strategies For Leaders To Counter Social Loafing Through The Use Of Organizational Citizenship Behavior: A Literature Review, Richard Hildreth

The Compass

Social loafing (SL) is a counterintuitive phenomenon that describes a decrease of efficiency observed in both small groups and large organizations. Research over the past century has increased our understanding of SL and identified antecedent factors that appear to reduce or exacerbate its effect. Subsequent organizational models have beenconceived and evolved, starting with organizational citizenship behavior (OCB), which led toward contextualperformance (CP), and recently to contextual and citizenship performance (CCP). Each type of model can provide valuable insight explaining employee behavior and under which contexts SL occurs. Research shows that OCB has improves organizational productivity and competitiveness, due to organizational …

Drinking And Game Day: The Expansion And Solution To Alcohol Abuse In Collegiate Sporting Events, Karan Arul

The Compass

For the typical American sports fans, a night out to watch a college sporting event involves a celebration of athleticism, spirit, and teamwork. However, as of the 21st century, the act of purchasing and consuming alcohol has become increasingly complimentary to “enjoying the game” in a collegiate sports stadium. In the United States, the National Collegiate Athletic Association (NCAA) is the frontrunner in proliferating collegiate athletics. Yet, the NCAA and its over 1200 member schools “enjoy great profitability from selling and advertising alcohol.”1 As college sporting events continue to rival their professional counterparts in popularity and allegiance, attending a college …

Essential Oils From Apple Mint (Mentha Suaveolens) And Passionflower Fruit (Passiflora Incarnata): Studies On Cognition, Coordination, And Chemical Components., Evelyn F. Patrick *, Jessie Bowers *, Shannon Read *, Brett R. Lackey, Christine Murphy, Sandra L. Gray

Journal of the South Carolina Academy of Science

Plant essential oils (EO) are used as perfumes, lotions and air fresheners because of their pleasant aromas, but EO also have the ability to elicit changes in mood and behavior. These activities are influenced by the mode of administration and by multiple signaling pathways. The EO aromas from organically grown apple mint (Mentha suaveolens) and passionflower fruit (Passiflora incarnata) were assessed for their effects on cognition and coordination. Participants completed two tasks designed to test working memory and bimanual task efficiency in rooms infused with apple mint, passionflower fruit or control EO. Bimanual coordination was assessed using the Intercept2 program …

Se Habla Español: The Health Disparity Among The Latino Population, Karen Paz

The Corinthian

Latinos are considered the fastest growing and the largest ethnic minority group in the United States. It is estimated that by 2050, 24% of the U.S. population will be Latino. According to Census data, approximately 18% of the U.S. population age five or older speaks a language other than English at home, and current projections continue to show increases in U.S. immigrant and second-language groups nationwide. About half of that population self-reported that they speak English less than “very well.” Members of this population are referred to as individuals with limited English proficiency (LEP). As the largest ethnic minority, 28 …
