Candida Albicans Hyphal Mannan Is Structurally Distinct From Yeast Mannan, Francis Kwofie

Electronic Theses and Dissertations

C. albicans is a polymorphic fungal pathogen which has the ability to shift from yeast to hyphae. C. albicans cell wall is composed of glucan, chitin, mannoprotein and mannan. It is not possible, using standard extraction methods, to isolate mannan from C. albicans hyphae. To isolate hyphal mannan, we developed a simplified alkali extraction method. Using this method it was determined that hyphal mannan has a much lower molecular weight, a smaller polymer distribution and altered conformation structure when compared to yeast mannan. The hyphal mannan was found to contain little to no acid-labile portion with only α-Man-PO₄ groups …

Algr Directly Controls Rsma In Pseudomonas Aeruginosa, Tyler Speaks

Electronic Theses and Dissertations

Pseudomonas aeruginosa is a bacterial pathogen that can infect any human tissue. The lungs of cystic fibrosis patients become chronically infected with Pseudomonas aeruginosa. Virulence factor gene expression is under elaborate regulatory control that remains poorly characterized. Understanding the regulatory hierarchy involved during infection is essential for identifying novel drug targets. RsmA is a post-transcriptional regulatory protein that controls expression of several virulence factors. Previous studies demonstrated alginate regulatory components AlgU and AlgR as regulators of rsmA expression. The aim of this study was to determine how AlgR controls rsmA expression. Western blot analysis of HA-tagged RsmA confirmed lower …

Electronic Theses and Dissertations

This investigation was an analysis of the interaction of adolescent exposure to methylphenidate (MPH; trade name: Ritalin) on nicotine sensitization and conditioned place preference (CPP) in a rodent model and underlying mechanisms of this effect. Animals were treated IP with 1 mg/kg MPH or saline using a ―school day‖ regimen of five days on, two days off, from postnatal day (P) 28-50. During the final two weeks of MPH treatment, animals were either behaviorally sensitized to nicotine (0.5 mg/kg free base) or saline for 10 days, or conditioned to nicotine or saline using the CPP behavioral paradigm. In addition, three …

Risk And Protective Factors Of Internalized Mental Illness Stigma, Kathleen Klik

Electronic Theses and Dissertations

The internalization of mental illness stigma is associated with an array of negative consequences; however, not all individuals experience the deleterious effects of internalized mental illness stigma. The present dissertation focuses on factors associated with internalized stigma, and will be the first to examine simultaneously both risk (i.e., shame, shame proneness and shame aversion, insight, and centrality and valence) and protective factors (social support and self-compassion) of internalized mental illness stigma. Using two of the most widely used assessments of internalized mental illness stigma (i.e., Self-Stigma of Mental Illness Scale [SSMIS] and the Internalized Mental Illness Scale [ISMI]), risk and …

Genetic Approaches In Comparative And Evolutionary Physiology, Jay F. Storz, Jaime T. Bridgham, Scott A. Kelly, Theodore Garland Jr.

Jay F. Storz Publications

Whole animal physiological performance is highly polygenic and highly plastic, and the same is generally true for the many subordinate traits that underlie performance capacities. Quantitative genetics, therefore, provides an appropriate framework for the analysis of physiological phenotypes and can be used to infer the microevolutionary processes that have shaped patterns of trait variation within and among species. In cases where specific genes are known to contribute to variation in physiological traits, analyses of intraspecific polymorphism and interspecific divergence can reveal molecular mechanisms of functional evolution and can provide insights into the possible adaptive significance of observed sequence changes. In …

We report on a Saudi infant with Holt-Oram syndrome caused by a de novo missense mutation of the TBX5 gene. The mutation (Thr72Lys) is novel and has not been previously reported. The cardiac and limb defects in our patient were both severe, and the infant also had micrognathia and cleft palate. Previously reported cases of the Holt-Oram syndrome caused by missense mutations were reviewed and their phenotypes were compared with the phenotype of our patient.

Development And Validation Of A State-Based Measure Of Emotion Dysregulation: The State Difficulties In Emotion Regulation Scale (S-Ders), Jason M. Lavender, Matthew T. Tull, David Dilillo, Terri Messman-Moore, Kim L. Gratz

Department of Psychology: Faculty Publications

Existing measures of emotion dysregulation typically assess dispositional tendencies and are therefore not well suited for study designs that require repeated assessments over brief intervals. The aim of this study was to develop and validate a state-based multidimensional measure of emotion dysregulation. Psychometric properties of the State Difficulties in Emotion Regulation Scale (S-DERS) were examined in a large representative community sample of young adult women drawn from four sites (N = 484). Exploratory factor analysis suggested a four-factor solution, with results supporting the internal consistency, construct validity, and predictive validity of the total scale and the four subscales: Nonacceptance (i.e., …

The Distribution Of Dissolved Barium Along The U.S. Geotraces North Atlantic Transect: Impact Of Biogeochemical Processes, Circulation And Phase Association, Karen Renee Grissom

Master's Theses

During the last four decades, since the completion of the GEOSECS program, there has been a growing interest in the biogeochemical cycle of barium (Ba) due to its potential as a proxy for interpreting the geologic record. The typical barium distribution exhibits removal in the upper water column and regeneration at depth, consistent with its classification as a bio-intermediate element and similar to the nutrient-like profiles of silicic acid and alkalinity. To better constrain the uses of Ba, trace element clean samples were collected during the North Atlantic US GEOTRACES cruises.

The cycling of barium in the North Atlantic region …

Latitudinal Variation In Thermal Tolerance And Preference Of Fundulus Notatus And F. Olivaceus: Implications For Temperature Mediated Reproductive Isolation, Laura Kristin Stewart

Master's Theses

Temperature is one of the most pervasive and influential abiotic factors affecting the life histories of fish, regulating a host of physiological processes and influencing behavioral thermoregulation. Fundulus notatus, the blackstripe topminnow, and F. olivaceus, the blackspotted topminnow, are widely distributed species located in drainages along the northern part of Gulf of Mexico (30°N latitude) and as far north as southern Illinois (39°N latitude). However, F. notatus has a much broader range reaching up into the Great Lakes (43°N latitude). Due to their broad geographical range, these populations inhabit a wide range of thermal regimes, thus …

Analyses Of Indices Of Abundance For Important Groundfish Species In The Northern Gulf Of Mexico From 1987-2009, Relative To Shrimp Bycatch; With Age And Growth Of Three Sciaenid Species, Allison Renee Odom

Master's Theses

Bycatch in the shrimp fishery became of particular concern in the 1980s during the peak of shrimp harvest in the northern Gulf of Mexico. Shrimp bycatch is of major importance because the majority of catch in the fishery is not intended target species of commercial shrimp, and most of the additional bycatch is returned to the sea dead or dying, inducing higher rates of mortality. This study was developed to assess the potential ecosystem effects of shrimp harvest on thirty selected species/species groups commonly encountered within the shrimp fishery as bycatch. Delta-lognormal modeling (DLM) was used to determine the relative …

Evaluation Of The Protein Recognition Properties Of Peptide Nucleic Acids, Crystal Cox Serrano

Master's Theses

The objective is to evaluate the ability of aminoacyl-tRNA synthetases (aaRS) to recognize the non-standard nucleic acid, PNA (peptide nucleic acid). PNA has immense potential in biomedical applications due to its increased thermostability and nuclease resistance over natural nucleic acids. PNA represents a superior alternative to natural nucleic acids in many biomedical applications due to its specificity, strong binding, and nuclease resistance. This study is the initial data set that indicates PNA are recognized by translation enzymes.

A Poetic Poioumenon: Coterie And Ekphrasis In David Lehman's "The Breeders' Cup", Anna Beth Rowe

Master's Theses

David Lehman’s poem “The Breeders’ Cup” uses cross-generational coterie and ekphrasis to create a poetic poioumenon. When read in terms of art criticism, Lehman’s “The Breeders’ Cup” models creative processes from the past and calls for a rehabilitative ethic in postmodern poetics. Lehman follows the ekphrastic form, which associates a poem with a work of visual art, from his New York School predecessor Frank O’Hara. “The Breeders’ Cup” addresses Édouard Manet’s 1865 painting Olympia through ekphrasis, and the painting of a prostitute becomes a patron saint of parody for postmodern poetics. The poem introduces lust as a metaphor for creative …

Geological Controls On Stratigraphy And Sedimentation Of The Mississippian Marshall Formation, Michigan Basin, U.S.A., Joseph G. Adducci

Masters Theses

An understanding of regional orogenic, climatic, and eustatic processes is critical to the interbasinal correlation of Paleozoic strata in eastern North America. Tectonic activity associated with the culmination of Appalachian Orogenic events has been shown to have regional influence on paleostructure and sediment dispersal in the Appalachian foreland basin and adjacent intracratonic Illinois and Michigan basins. The culmination of the Acadian Orogeny at the end of the Devonian represents the beginning of a period of general tectonic quiescence extending throughout the early and middle Mississippian in eastern North America. Early Mississippian strata in the Michigan basin is distinctive and marks …

Breastfeeding With The Bronson Mothers’ Milk Bank, Marykate Bodnar

Masters Theses

Bronson Methodist Hospital in Kalamazoo is home to one of only 15 certified breast milk banks in the United States. Women have shared breast milk for centuries through wet nurses, but this institutionalized and regulated version of sharing is distinct from previous forms. Breastfeeding has become a symbol of successful motherhood; donor milk adds a new dimension to this aspect of idealized motherhood. This study explores how the milk bank works: its organizational structure within a hospital, how donors are selected, and how recipients qualify for donor milk. It is grounded in Feminist and Medical Anthropology literature. Using semi-structured interviews …

The purpose of this study was to evaluate the feasibility of experimental research procedures and gather initial data in studying the experience of social flow within the context of group music production tasks. Participants completed two different group vocal music production tasks: Performance of a pre-composed song and an improvised performance. The Flow State Scale-2 (FSS-2), a 36-item survey in which a mean score of 45 implies the ultimate flow experience and a score of 9 implies that no flow was experienced during the event in question, was used to assess the level of social flow experienced by the participants …

Biogeochemical Alteration Of Particulate Pyrogenic Organic Carbon (Pyc), Jason Matthew Stuart

Master's Theses

The resistance of plant derived pyrogenic organic carbon (pyC) to abiotic and biotic means of degradation has led to increased interest in the role of pyC as a potential carbon sink, as well as a strategy for sequestering atmospheric CO2 to mitigate excess carbon emissions. Though much research pertaining to the fundamental properties of pyC degradation have been performed in a controlled lab setting, there has been very little work regarding pyC degradation in a field setting where factors such as precipitation and temperature fluctuate seasonally. This work focuses on various degradation characteristics of two …

Ichthyoplankton Composition In The Loop Current And Sargassum Habitats In The Northern Gulf Of Mexico, Stephanie Morgan Taylor

Master's Theses

Ichthyoplankton in the Gulf of Mexico (GOM) aggregate in two different habitats that serve to provide refuge and concentrate prey in an otherwise oligotrophic environment: the Loop Current (LC) a mesoscale oceanographic feature characterized by the transition of environmental conditions of the water mass between the GOM and Caribbean; and Sargassum, a two species assemblage of floating brown algae that is habitat for many larval and juvenile obligate and associated fishes. The objectives of this study were to characterize the density and community composition of ichthyoplankton within these habitats using multivariate analysis. I identified three unique assemblages of ichthyoplankton …

Naturalists’ Perspectives On The Use Of Mobile Technology During A Nature Hike, Aubin Marishka Radzewicz St. Clair

Master's Theses

Naturalists act as our link between scientific knowledge and the public’s understanding of natural history and conservation efforts. In order for them to succeed, they need access to reference materials as well as up-to-date information (Mankin, Warner, & Anderson, 1999). Incorporating mobile technology (i.e. tablets) into naturalists’ endeavors in natural history and environmental education can be used as supportive and educational tools. My project investigated how newly trained naturalists used tablet technology while leading groups of children on nature hikes. I investigated naturalists’ views on the use of mobile technology as a tool during the hikes. My research was guided …

Elucidating The Molecular Function Of Reprolysin Metalloproteases In Tick-Host-Pathogen Interaction, Jaclyn Bo Williams

Master's Theses

Ticks are ectoparasites that attach to their host for many days to weeks, feeding to engorgement and continuing their species life cycle. The mechanisms behind the successful feeding and manipulation of host immune responses have been associated with the secretion of their specialized saliva. Tick saliva includes a variety of modulatory molecules that must disrupt and counteract defense mechanisms, including a variety of proteases. Reprolysin Metalloproteases, in the Zn²⁺ dependent family, is secreted as a proenzyme and is shown to have proteolytic activity, degrading fibrinogen and gelatinase activity, as well as disturbing homeostasis¹². Previous work with …
