Myosin Ii Isoforms In Breast Cancer: Role Of Contractility In Matrix Organization, Cell Migration, And Endothelial Barrier Function, Bridget Ruth Hindman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Breast cancer is a devastating and complicated disease. A large proportion of breast cancer related deaths are due to metastasis. Metastasis is when cancer cells leave the primary tumor, travel through the bloodstream, and proliferate in distant sites. Cell contractility is involved in a number of cellular processes associated with metastasis including matrix organization, tumor cell migration, and endothelial cell barrier function. The main regulator of contractility in nonmuscle cells is nonmuscle myosin II. There are three isoforms of this protein: myosin IIA, IIB, and IIC. The specific roles of the individual isoforms in cancer progression and metastasis have yet …

The Longest Common Subsequence Via Generalized Suffix Trees, Tazin Afrin Jan 2015

The Longest Common Subsequence Via Generalized Suffix Trees, Tazin Afrin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Given two strings S1 and S 2, finding the longest common subsequence (LCS) is a classical problem in computer science. Many algorithms have been proposed to find the longest common subsequence between two strings. The most common and widely used method is the dynamic programming approach, which runs in quadratic time and takes quadratic space. Other algorithms have been introduced later to solve the LCS problem in less time and space. In this work, we present a new algorithm to find the longest common subsequence using the generalized suffix tree and directed acyclic graph.;The Generalized suffix tree (GST) is the …

Role Of Multi-Site Phosphorylation In Regulation Of E(Spl) M8 Activity During Drosophila Neurogenesis, Mohna Bandyopadhyay

Graduate Theses, Dissertations, and Problem Reports (ETD)

Notch signaling is an evolutionarily conserved pathway that regulates cell-fate determination at various stages of development in invertebrate and vertebrate species. The Notch pathway mediates juxtacrine signaling through a process termed as lateral inhibition by which two equipotent cells adopt distinct cell fates. The functions of Notch have been exceptionally well analyzed during neurogenesis in Drosophila, particularly during eye and mechanosensory bristle morphogenesis. At the onset of neurogenesis, proneural bHLH activators encoded by atonal (ato) or the achaete-scute complex (ASC) is expressed in groups of cells, called proneural clusters (PNCs) in the eye and the bristle tissue respectively. From each …

Parameterized Strings: Algorithms And Applications, Richard Beal Jan 2015

Parameterized Strings: Algorithms And Applications, Richard Beal

Graduate Theses, Dissertations, and Problem Reports (ETD)

The parameterized string (p-string), a generalization of the traditional string, is composed of constant and parameter symbols. A parameterized match (p-match) exists between two p-strings if the constants match exactly and there exists a bijection between the parameter symbols. Historically, p-strings have been employed in source code cloning, plagiarism detection, and structural similarity between biological sequences. By handling the intricacies of the parameterized suffix, we can efficiently address complex applications with data structures also reusable in traditional matching scenarios. In this dissertation, we extend data structures for p-strings (and variants) to address sophisticated string computations.;We introduce a taxonomy of classes …

Assessing And Meeting Residents' Needs: An Evaluation Of Residence Hall Programming, Michael J. Beck Jan 2015

Assessing And Meeting Residents' Needs: An Evaluation Of Residence Hall Programming, Michael J. Beck

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this qualitative study, I examine how programming in college residence halls does and does not meet the needs of residents and resident assistants. Using focus group and individual interview data, I structure my analysis using Maslow's (1954) hierarchy of needs. I suggest that residence hall programming---academic, social, or a hybrid of the two---is most valuable for its ability to meet residents' needs related to belongingness but that residence hall staff must place more explicit emphasis on residents' growth needs in order for self-actualization to be supported.

Emotion Socialization And Autism Spectrum Disorder: The Role Of Disability Severity And Parental Attributions In Predicting Parents' Emotional Responses, Hilary R. Bougher

Graduate Theses, Dissertations, and Problem Reports (ETD)

The importance of parents in emotion socialization is highly established among children who are typically developing (Sheffield Morris, Silk, Steinberg, Myers, & Robinson, 2007). Child characteristics, such as child temperament and emotional reactivity, have been found to influence parenting (Bell & Chapman, 1986; Belsky, 1984). However, little is known about the emotion socialization practices of parents of children with special needs and how disability severity may influence these practices. Participants included 68 parents of children with autism spectrum disorder (ASD) (ages 3-11). Parents reported on three dimensions, using three questionnaires: disability severity via the Vineland Adaptive Behavior Scales, 2nd edition …

The Role Of Adenosine Monophosphate Activated Protein Kinase In Luteal Progesterone Production, Elizabeth Compton Bowdridge Jan 2015

The Role Of Adenosine Monophosphate Activated Protein Kinase In Luteal Progesterone Production, Elizabeth Compton Bowdridge

Graduate Theses, Dissertations, and Problem Reports (ETD)

Prostaglandin F2 alpha (PGF2&agr;) has in vivo luteolytic actions on the bovine corpus luteum (CL). Although PGF2&agr; is utilized extensively in livestock to synchronize estrus, its actions in vitro are controversial and do not always result in a reduction in progesterone (P4) secretion. The mechanism of action of PGF2&agr; is thought to involve activation of the phospholipase C-Ca2+ pathway. The luteolytic actions of PGF2&agr; are mediated through an elevation of cytosolic Ca2+ involving activation of protein kinase C (PKC). Expression of PKC isozymes and calcium/calmodulin-dependent protein kinase kinase 2 (CAMKK2) change as the CL develops to a mature stage. Either …

Use Of Protein Immobilization To Measure Cytochrome P450 Conduction And Metabolism Kinetics, Christopher D. Bostick Jan 2015

Use Of Protein Immobilization To Measure Cytochrome P450 Conduction And Metabolism Kinetics, Christopher D. Bostick

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cytochrome P450s (P450s) are a large family (>11,000) of heme thiolated proteins that are responsible for ~ 75% of the metabolism of pharmaceuticals on the market. Understanding P450 mediated metabolism is crucial for accurate in vitro predictions of drug metabolism. P450 protein-protein interactions have been shown to alter enzyme catalytic activity. Furthermore, these interactions are isoform specific, and can elicit activation, inhibition, or no effect on enzymatic activity. Studies show these effects are also dependent on the protein binding partner cytochrome P450 reductase (CPR), and the order of protein addition to purified reconstituted enzyme systems. In the current work, …

The Diverse Relationship Of Kruppel-Like Factors 4 And 5 In Breast Cancer, Mark K. Farrugia Jan 2015

The Diverse Relationship Of Kruppel-Like Factors 4 And 5 In Breast Cancer, Mark K. Farrugia

Graduate Theses, Dissertations, and Problem Reports (ETD)

Kruppel-like factors (KLFs) are transcription factors that participate in numerous biological functions, mainly impacting cell fate and differentiation. KLFs 4 and 5 (KLF4/5) are two highly studied members of this family, implicated to have diverse roles in both normal and abnormal physiology. KLF4 is primarily expressed in post-mitotic, differentiated epithelium and consistent with this observation, KLF4 exerts suppressive effects on cellular growth. Paradoxically, KLF4 can promote malignant features in both squamous cell carcinoma of the skin and breast cancer. We have attempted to better understand the nature of KLF4 in cancer via its relationship with KLF5. Although the two are …

Sports Investment, Beliefs About Food-Related Behaviors, And Engagement In Problematic Eating Behaviors During Adolescence, Kaitlyn A. Ferris Jan 2015

Sports Investment, Beliefs About Food-Related Behaviors, And Engagement In Problematic Eating Behaviors During Adolescence, Kaitlyn A. Ferris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Involvement in sport is the most widely reported organized activity among children and adolescents. To date, organized sports also represent the only organized activity examined in conjunction with youths' eating behaviors. Organized sports serve as contexts where messages about healthy eating and body image are communicated, and adolescents' beliefs about food and their bodies' degree of thinness and muscularity has the potential to be amplified in such settings as youth strive to perform at high levels during athletic competitions. However, inconsistency in the measurement of both organized sports participation and adolescents' engagement in problematic under- and over-eating behaviors has resulted …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Oak regeneration challenges are a widespread issue across the mixed oak and mixed mesophytic forests of the eastern United States. Following disturbance on many mesic and sub-mesic sites oaks are being replaced by faster growing or shade tolerant species. There are many contributing factors, but one thought to have the strongest influence is attributed to the effects of 20th century fire suppression. For millennia fire was an integral part of oak dominated ecosystems and is thought to have contributed to and perpetuated oak's importance in these forests. During the 20th century the frequency and spatial scale of fire was severely …

Graduate Theses, Dissertations, and Problem Reports (ETD)

The application of bioremediation as a means to ameliorate potentially toxic metals from contaminated soils has been on the forefront of sustainable technologies in the field of environmental studies. Conventional methods available for soil remediation are employed in both in situ or ex situ and these are: soil flushing, solidification/stabilization, vitrification, electrokinetics, chemical reduction/oxidation, soil washing, and excavation. In general, these technologies are limited by their applicability to small areas and the high costs to execute. The use of biota, in particular fungi and trees, has been an emerging low-cost and "environmentally-friendly" alternative to conventional technologies. In this study, I …

Dimensions Of Political Reasoning: Associations Among Informational Assumptions, Sociopolitical Values, And Domain-Specific Judgments About Laws, Benjamin Oosterhoff Jan 2015

Dimensions Of Political Reasoning: Associations Among Informational Assumptions, Sociopolitical Values, And Domain-Specific Judgments About Laws, Benjamin Oosterhoff

Graduate Theses, Dissertations, and Problem Reports (ETD)

Adolescents' beliefs about laws are a critical component of their emerging political reasoning, which is hypothesized to guide political decisions in adulthood. Laws serve a variety of purposes by restricting certain social behaviors. However, little is known about the types of laws adolescents view as important and obligatory to obey, or the amount of punishment that should be received for breaking different laws. Identifying individual differences in these beliefs may help elucidate the developmental origins of political attitudes. Therefore, the current study had three primary goals. The first goal was to utilize social domain theory to assess adolescents' judgments and …

An Examination Of Households' Willingness-To-Pay For Wetlands Biodiversity Conservation In The United States: A Benefit Transfer Approach, Rajendra Prasad Poudel Jan 2015

An Examination Of Households' Willingness-To-Pay For Wetlands Biodiversity Conservation In The United States: A Benefit Transfer Approach, Rajendra Prasad Poudel

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research paper provides a benefit transfer model of willingness-to-pay (WTP) for wetlands' biodiversity conservation in the United States. The validity of the estimated wetland's willingness-to-pay values is also examined. While valuation of the services provided by wetlands may be challenging due to their non-market nature, estimation of values is important. Conducting a primary study is the best option for precise results. However, researchers may recommend the benefit transfer approach in wetland valuation when there are limited time, budgetary constraints, and administrative urgency.;The benefit transfer approach involves transferring of value estimates from study sites (where research was already undertaken) to …
