Preparation And Purification Of Enlarged Multinucleated U937 Human Leukemia Cells And Their Susceptibility To Physical Damage By Ultrasound, Kathryn Gold

Renée Crown University Honors Thesis Projects - All

Multinucleation occurs in neoplastic cells that have been treated with cytochalasin B, a fungal toxin that disrupts actin microfilament structures. When the actin cytoskeleton is disrupted, contractile ring formation and cytokinesis are inhibited. In normal cells cytochalasin B prevents the cells from entering the cell cycle. However in neoplastic cells, since cytokinesis no longer occurs, the dividing cell becomes enlarged and heavily multinucleated. We propose that enlarged leukemia cells may be more sensitive to ultrasound treatment because of their increased size and weakened cytoskeletal structure. To determine the differential chemical and physical response of enlarged, multinucleated cells in comparison with …

Risk Factors And Their Effects On The Comorbidity Of Asthma And Anxiety Disorders In School Aged Children, Stephanie P. Seigel

Renée Crown University Honors Thesis Projects - All

Asthma is the most common chronic childhood disease, characterized by attacks that make a child or adult feel like they are unable to breathe (Shohat, Graif, & Garty, 2005). Currently, nearly 6.3 million children between the ages of 5 and 14 are afflicted with asthma (EPA, 2006)

Children with asthma are also more prone to developing other disorders especially, anxiety. The prevalence of child patients with asthma suffering from anxiety disorders is found to be as high as 4.7% (Katon, Richardson, Lozano & McCauley, 2004). The current study aims to examine the risk factors that contribute to the comorbidity of …

Players The First Magazine Dedicated To Young Female Athletes And Women’S College Sports Fans., Stephanie Plotino

Renée Crown University Honors Thesis Projects - All

The involvement of women in athletics has exploded over the last 10 years. This project capitalizes on this changing dynamic by creating a prototype of a women’s college sports magazine called Players. No such magazine currently exists in the United States, but I believe there is a market for it among teenage female athletes who are interested in women’s college sports. Without Players, females have only male-dominated publications like Sports Illustrated or ESPN for general sports coverage, or they can read more female-friendly publications such as Shape and Fitness, which cater to an active lifestyle but do …

A Framework For Understanding Ecological Traps And An Evaluation Of Existing Evidence, Bruce A. Robertson, Richard L. Hutto

Biological Sciences Faculty Publications

When an animal settles preferentially in a habitat within which it does poorly relative to other available habitats, it is said to have been caught in an “ecological trap.” Although the theoretical possibility that animals may be so trapped is widely recognized, the absence of a clear mechanistic understanding of what constitutes a trap means that much of the literature cited as support for the idea may be weak, at best. Here, we develop a conceptual model to explain how an ecological trap might work, outline the specific criteria that are necessary for demonstrating the existence of an ecological trap, …

Invasive Plant Suppresses The Growth Of Native Tree Seedlings By Disrupting Belowground Mutualisms, Kristina A. Stinson, Stuart A. Campbell, Jeff R. Powell, Benjamin E. Wolfe, Ragan M. Callaway, Giles C. Thelen, Steven G. Hallett, Daniel Prati, John N. Klironomos

Biological Sciences Faculty Publications

The impact of exotic species on native organisms is widely acknowledged, but poorly understood. Very few studies have empirically investigated how invading plants may alter delicate ecological interactions among resident species in the invaded range. We present novel evidence that antifungal phytochemistry of the invasive plant, Alliaria petiolata, a European invader of North American forests, suppresses native plant growth by disrupting mutualistic associations between native canopy tree seedlings and belowground arbuscular mycorrhizal fungi. Our results elucidate an indirect mechanism by which invasive plants can impact native flora, and may help explain how this plant successfully invades relatively undisturbed forest habitat.

Hiring Criteria In Biology Departments Of Academic Institutions, Christine M. Fleet, Meredith F.N. Rosser, Rebecca A. Zufall, Marney C. Pratt, Tracy S. Feldman, Paula P. Lemons

Biological Sciences: Faculty Publications

We surveyed faculty in the biology departments of US institutions of higher education to compare the experience and training valued by faculty at hiring institutions with the experience and training most graduate students receive. Our data show that associate, baccalaureate, and master's institutions value teaching experience and skills more highly than research skills. In contrast, doctoral institutions place a higher value on the ability to publish research and obtain outside funding. These findings provide quantitative and qualitative insight into discrepancies between the values of those who train graduate students in biology and the expectations of the institutions likely to hire …

Examination Of Perceived Stress And Coping Mechanisms Among Midwest, Undergraduate, Bachelor Of Science Nursing Students, Seth T. Dorman

Theses and Dissertations

Stress is a concept that affects everyone and has been linked to increased incidences of depression and anxiety as well as causing a variety of physical symptoms. College students have been shown to be at an increased risk for higher levels of stress. While studies have been conducted looking at stress levels and causes of stress in undergraduate nursing students in other countries, very few of these studies have been conducted on a population of students within the United States. The purpose of this study was to examine variables that affect levels of stress in undergraduate Bachelor of Science nursing …

The Effects Of Pre-Natal Exposure To Arsenic On Gene Expression In Fetal Rat Brain, Darryl L. Kelly

Theses (Pre-2016)

The purpose of this study was to examine the effect of arsenic exposure during gestation on the expression of specific marker genes associated with cell proliferation and oxidative stress. Arsenic is a naturally occurring substance that can be found in soil and / water. Drinking water is the primary source of arsenic exposure, via underground wells or rainwater. A potential source of arsenic in our environment is a byproduct of copper smelting arsenic occurs naturally in copper ores. Both the experimental as well as epidemiological evidence suggests that arsenic exposure is a risk factor for various human diseases including cancer. …

Silicon Uptake In Hydroponically Grown Wheat, Ibukun Aladejana

Theses (Pre-2016)

Microbial contamination of hydroponics systems continues to be a major concern in life support experimental trials. Research shows that when silicon is readily available to monocotyledonous plants, it plays a large role in their growth, mineral nutrition, mechanical strength and resistance to fungal disease. Also, omission of silicon from solution cultures may lead to distorted results in experiments on inorganic plant nutrition, growth, development and responses to environmental stress. Silicon has been shown to accumulate in tissues of various dicotyledonous plants, for example, cucumber and in monocotyledonous plants for example rice and wheat. However, it remains unclear whether or not …

Periodic Difference Equations, Population Biology And The Cushing-Henson Conjectures, Saber Elaydi, Robert J. Sacker

Mathematics Faculty Research

We show that for a k-periodic difference equation, if a periodic orbit of period r is globally asymptotically stable (GAS), then r must be a divisor of k. Moreover, if r divides k we construct a non-autonomous dynamical system having minimum period k and which has a GAS periodic orbit with minimum period r. Our method uses the technique of skew-product dynamical systems. Our methods are then applied to prove two conjectures of J. Cushing and S. Henson concerning a non-autonomous Beverton-Holt equation which arises in the study of the response of a population to a periodically …

Down Regulation Of Dna Repair Genes Coupled With Oxidative Stress Exposed To Modelled Microgravity, Gulbanu Hashim

Theses (Pre-2016)

Research has shown that microgravity induces oxidative stress. In this study, we examined the testis from 6-8 weeks old BALB mice exposed to the ground hind-limb unloading model for 7 days. This model has been shown to simulate a microgravity environment. Total RNA was isolated from the testes of both treatment and control groups and Quantitative Real-Time PCR was performed to analyze the expression of genes controlling DNA excision repair pathways. Manganese superoxide dismutase (MnSOD) gene was examined to detect oxidative stress; and the PCNA (Proliferating Cell Nuclear Antigen) gene expression was analyzed to detect repair synthesis as well as …

You Can't Believe The Joy! A Biological Theological View Of Suffering, Justin Miller

Verbum

In lieu of an abstract, below is the essay's first paragraph.

“Consider it pure joy whenever you go through any sort of trial. Realize that when your faith is tested this makes for endurance. Let endurance come to its perfection so that you may be fully mature and lacking in nothing.” (Jam 1: 2-4). The Book of James speaks tough words that seem the opposite of our societal notions concerning suffering. At first, such a claim seems outrageous, not grounded in reality, and provides no real solace to those suffering. It leads one to question: why must human beings suffer, …

Secondary N-Nitrosocarbamate Anions: Structure And Alkylation Reactions. A Dft Study, Vladimir Benin

Chemistry Faculty Publications

The current article reports theoretical studies (DFT: B3LYP/6-31+G(d)) on the structure and alkylation reactions of the anions of some secondary N-nitrosocarbamates, a class of ambident nucleophiles whose chemistry has been little explored. Several anions (1–4), with an increasing size of the carbamate alkyl (aryl) group were investigated, in an attempt to establish the influence of the size of that group on the thermal stability and regioselectivity of alkylation of the title anions. The conclusion is that thermal stability and the mode of reaction are affected significantly only in the presence of very large and branched carbamate groups. The thermal …

Utilizing The Brief Symptom Inventory As A Prediction Tool For Treatment Response In Patients With Serious Mental Illness, Ryan Curtis Dix

Doctor of Psychology (PsyD)

Current data suggest that the cost of caring for people with serious mental illness in the United States was 2.64 billion dollars in the years between 1997 and 2004. The proper utilization of these funds is an important consideration if we are to successfully address the needs of this population. To maximize the use of mental health funds, the provider must quickly identify effective and efficient treatments. Assessment can facilitate the screening process and subsequent treatment decisions. For that reason, my research question addresses the issue of effective screening measures notably the Brief Symptom Inventory (BSI) in predicting movement through …

Matsigenka Corporeality, A Nonbiological Reality: On Notions Of Consciousness And The Constitution Of Identity, Dan Rosengren

Tipití: Journal of the Society for the Anthropology of Lowland South America

Departing from the specific case of Matsigenka people in the Montaña of southeastern Peru, this article challenges some of the assumptions associated with predominant conceptions of Amazonian perspectivism. Examining different cultural registers such as birth rituals and mythology, Matsigenka peoples’ notions about being, soul, and self are discussed in relation to the importance that often is ascribed to physical shape for conceptualizing the world. In contrast to this stress on the corporeal, it is argued that Matsigenka people consider the noncorporeal cognizant self to determine outlook and identity. In accordance, corporeal transformation is seen as a result of “the self …
