Mitogen activated protein kinases (MAPKs) are Ser/Thr kinases that relay the extracellular signal into intracellular responses and regulate several biological responses. They are classified into conventional MAPKs and atypical MAPKs. Extracellular signal regulated kinase 3 (ERK3) is an atypical MAPK that has a single phospho-acceptor site (Ser 189) in its activation motif instead of the canonical Thr-Xaa-Tyr (TXY) motif of conventional MAPK like ERK1/2. ERK3 comprises of a unique C terminal tail and a central C34 domain that further distinguishes it from ERK1/2. Moreover, compared to ERK1/2, much less is known about the upstream activators and the downstream targets of …

Role Of Dyslipidemia On Lipid Metabolism In Maintenance Hemodialysis Patients, Eno Latifi
Role Of Dyslipidemia On Lipid Metabolism In Maintenance Hemodialysis Patients, Eno Latifi
Wayne State University Dissertations
Maintenance hemodialysis (MHD) patients experience various abnormalities such as systemic inflammation (SI), oxidative stress (OS), and dyslipidemia (D). Defined as an imbalance of plasma lipids, lipoproteins, and lipid metabolism enzymes, D has been associated with a rise in morbidity and mortality within ESRD patients due to cardiovascular disease (CVD). However, the contribution of each of these parameters to D is poorly understood; moreover, the impact of the following parameters on dyslipidemia in different ethnicities is unknown. Hence, the objective of this study was to characterize D in a multi-ethnic cohort of ESRD patients. We hypothesized that the degree of dyslipidemia …
Betting & Hierarchy In Paleontology, Leonard Finkelman
Betting & Hierarchy In Paleontology, Leonard Finkelman
Faculty Publications
In his Rock, Bone, and Ruin: An Optimist’s Guide to the Historical Sciences, Adrian Currie argues that historical scientists should be optimistic about success in reconstructing the past on the basis of future research. This optimism follows in part from examples of success in paleontology. I argue that paleontologists’ success in these cases is underwritten by the hierarchical nature of biological information: extinct organisms have extant analogues at various levels of taxonomic, ecological, and physiological hierarchies, and paleontologists are adept at exploiting analogies within one informational hierarchy to infer information in another. On this account, fossils serve the role …
The Effects Of Medical Marijuana On The Endocannabinoid Systems Of Children With Autism Spectrum Disorders, Maya Eylon
The Effects Of Medical Marijuana On The Endocannabinoid Systems Of Children With Autism Spectrum Disorders, Maya Eylon
Whittier Scholars Program
50% of children with Autism Spectrum Disorder(ASD) have behavior abnormalities ranging from anxiety, to tantrum, to behavior outbreaks. Of these children, 40% are not responding to the treatment options available today (behavior therapy and medical treatments). There is a need within the ASD community that is not being address and because of that the desperate parents of these children have been turning to unconventional treatments, such as medical marijuana. Although there have been several anecdotes speaking to the power of cannabis, there is a severe slack of scientific data and research to demonstrate the effectiveness of cannabis in treating these …

Biomedical Research Institute Publications and Presentations
The evolution of multicellular metazoan organisms was marked by the inclusion of an extracellular matrix (ECM), a multicomponent, proteinaceous network between cells that contributes to the spatial arrangement of cells and the resulting tissue organization. The development of an ECM that provides support in larger organisms may have represented an advantage in the face of selection pressure for the evolution of the ECM.

Selective Distant Electrostimulation By Synchronized Bipolar Nanosecond Pulses, Elena C. Gianulis, Maura Casciola, Carol Zhou, Enbo Yang, Shu Xiao, Andrei G. Pakhomov
Bioelectrics Publications
A unique aspect of electrostimulation (ES) with nanosecond electric pulses (nsEP) is the inhibition of effects when the polarity is reversed. This bipolar cancellation feature makes bipolar nsEP less efficient at biostimulation than unipolar nsEP. We propose to minimize stimulation near pulse-delivering electrodes by applying bipolar nsEP, whereas the superposition of two phase-shifted bipolar nsEP from two independent sources yields a biologically-effective unipolar pulse remotely. This is accomplished by electrical compensation of all nsEP phases except the first one, resulting in the restoration of stimulation efficiency due to cancellation of bipolar cancellation (CANCAN-ES). We experimentally proved the CANCAN-ES paradigm by …

Supporting Teacher And Student Competency With Scientific Practices Through Lesson Study, Jonathan Robert Bowers
Browse all Theses and Dissertations
Although numerous studies have documented the benefits of using scientific practices in K-12 education, many in-service teachers continue to use traditional pedagogical practices. In order to address the underlying deficiencies in teacher pedagogical design capacity (PDC) for practices, we developed a lesson study (LS) based professional learning (PL) program, which we implemented at a low socio-economic status (SES) school district. Using classical content analysis and supplementary assessments, I investigated the impact this LS based PL program had on teacher PDC for scientific practices (particularly the practice of argumentation), student argumentation competency, and teacher self-efficacy. My results demonstrate that teacher PDC …
Examination Of Behavioral Lateralizations In Juvenile Tarantulas In The Presence Of Prey Odors, Matthew Angelosanto
Examination Of Behavioral Lateralizations In Juvenile Tarantulas In The Presence Of Prey Odors, Matthew Angelosanto
Senior Honors Theses and Projects
The functional and/or structural specialization of the left or right side of the brain (behavioral lateralization) has substantial impacts on the interactions an animal makes with other organisms and its surroundings. While this has been extensively shown throughout vertebrates, it has recently been demonstrated in various taxa of invertebrates. Despite this, its presence in arachnids, and specifically tarantulas, remains poorly understood. The purpose of this study was to determine whether behavioral lateralization is present in the juvenile tarantulas Pterinochilus murinus and Brachypelma albopilosum in response to prey odors. If behavioral lateralization was found, I aimed to detennine how it differed …

Effects Of Coral Reef Habitat Complexity On The Community Composition And Trophic Structure Of Marine Fish Assemblages In Indonesia’S Wakatobi Marine National Park, Kuyer Josiah Fazekas Jr.
Browse all Theses and Dissertations
The coral reefs within Indonesia’s Wakatobi Marine National Park support a high diversity of reef-building hard corals and associated marine fish. Climate change threatens to dramatically affect coral reef ecosystems by altering the interactions between reef fish and the specific microhabitats they depend on for survival. To examine the spatially varied effects of habitat complexity on the community composition and trophic structure of marine fish assemblages, I analyzed fish community and habitat complexity data across reef zones. Habitat complexity metrics were: structural complexity, the percentage of hard coral (HC) cover, HC genera richness, HC genera diversity (Shannon index), and HC …
Description And Alleviation Of The Stress Response In Atlantic Sharpnose Sharks (Rhizoprionodon Terraenovae), White-Spotted Bamboo Sharks (Chiloscyllium Plagiosum), And Golden Shiners (Notemigonus Crysoleucas), Lauren Nicole Fuller
Electronic Theses and Dissertations
Sharks are an essential component of many marine ecosystems; however they have experienced population declines mainly attributed to overfishing and capture of sharks as bycatch. Despite sharks often being released when captured as bycatch the act of capture can result in a stress response which may cause severe physiological perturbations. Studies have investigated the physiological impacts of capture stress on elasmobranchs but most have primarily focused on the secondary stress response. I conducted a series of studies to further describe the primary stress response through quantification of adrenocorticotropic hormone (ACTH) while also investigating methods such as sedation and limiting air …
Application And Refinement Of Molecular Ecology Techniques For Amphibian Conservation, Stephanie Marie Burgess
Application And Refinement Of Molecular Ecology Techniques For Amphibian Conservation, Stephanie Marie Burgess
Electronic Theses and Dissertations
Wildlife conservation has become increasingly difficult due to habitat loss habitat fragmentation and land use change. Thus conservationists have embraced advances in molecular ecology such as landscape genetics and microbial bioinformatics that employ genetic techniques to further understand the relationship between individuals and their environment. In landscape genetics model inferences can be used to identify features that facilitate or resist gene flow providing a framework for anticipating the impacts of land use changes on a species’ ability to disperse. However the factors that affect the transferability of landscape genetics inferences are poorly understood and little is known about the effect …

Transgenerational Plasticity Is Sex-Dependent And Persistent In Yellow Moneyflower (Mimulus Guttatus), Kayla Akkerman
Transgenerational Plasticity Is Sex-Dependent And Persistent In Yellow Moneyflower (Mimulus Guttatus), Kayla Akkerman
All Master's Theses
Transgenerational phenotypic plasticity, whereby environmental cues experienced by parents alter the phenotype of their progeny, has now been documented in diverse organisms. Transmission of environmentally determined responses is known to occur through both maternal and paternal gametes, but the underlying mechanisms have rarely been compared. In addition, the persistence of induction over multiple generations appears to vary widely but has been characterized for relatively few systems. Yellow monkeyflower (Mimulus guttatus) is known to exhibit transgenerational induction of increased glandular trichome production in response to simulated insect damage. Here we test for differences between maternal and paternal transmission of …

Characterization And Analysis Of Proteins Secreted By The Mutant Pichia Pastoris Strain, Bgs13, Christopher Alan Naranjo
Characterization And Analysis Of Proteins Secreted By The Mutant Pichia Pastoris Strain, Bgs13, Christopher Alan Naranjo
University of the Pacific Theses and Dissertations
The methylotrophic yeast Pichia pastoris has been utilized for heterologous protein expression for research, clinical, and industrial purposes to produce thousands of recombinant protein products. Because P. pastoris secretes very few of its own proteins, the exported recombinant protein is the major polypeptide in the extracellular medium, making purification relatively easy. Unfortunately, a disadvantage to the programmed export is that some recombinant proteins intended for secretion are retained within the cell and may be subsequently degraded. A mutant strain isolated in our lab, containing a pREMI-derived disruption of the BGS13 gene, has displayed elevated levels of secretion for a variety …
Regional Patterns Of Vascularity Within The Limb Bones Of Small And Large-Bodied Bats, Logan Usher
Regional Patterns Of Vascularity Within The Limb Bones Of Small And Large-Bodied Bats, Logan Usher
Williams Honors College, Honors Research Projects
Bats have humeri and femora that are poorly vascularized or avascular compared to birds, with only larger bats typically displaying vascular canals. Vascular canals provide passageways for blood vessels and nerves, which help maintain bone homeostasis, and support bones by resisting torsional stresses placed on them. The presence of a greater number of canals in large bats suggests that they may have a larger need for the support of nutrient and waste exchange than their dense lacunar-canalicular system can provide on its own. The focus of the current project will be to analyze SR micro-CT data from various bat humeri …
City Limits: Heat Tolerance Is Influenced By Body Size And Hydration State In An Urban Ant Community, Dustin Jerald Johnson
City Limits: Heat Tolerance Is Influenced By Body Size And Hydration State In An Urban Ant Community, Dustin Jerald Johnson
University of the Pacific Theses and Dissertations
Cities are rapidly expanding, and global warming is intensified in urban environments due to the urban heat island effect. Therefore, urban animals may be particularly susceptible to warming associated with ongoing climate change. Thus, I used a comparative and manipulative approach to test three related hypotheses about the determinants of heat tolerance or critical thermal maximum (CTmax) in urban ants—specifically, that (1) body size, (2) hydration status, and (3) preferred micro-environments influence CTmax. I further tested a fourth hypothesis that native species are particularly physiologically vulnerable in urban environments. I manipulated water access and determined CTmax for 11 species common …

The goals of my thesis are to: 1) identify species of bats in Wright State University’s (WSU) campus woods via acoustic surveys to compare to detections from previous years (Chapter 1) (2) analyze occupancy and detection probabilities of Indiana bats in different areas throughout the woods (Chapter 1), and 3) create an acoustical approach to analyze habitat use through bat social calls (Chapter 2). In Chapter 1, I conducted stationary acoustic surveys in the Wright State University woods in hydric (riparian), edge, and old growth habitats to record bat vocalizations. The WSU woods have a diverse bat community as ten …

Identification Of A Hybrid Lethal Gene On The X Chromosome Of Caenorhabditis Briggsae, John Kelly Dougherty
Browse all Theses and Dissertations
Two closely related Caenorhabditis species, C. briggsae and C. nigoni are cross fertile and produce viable adult progeny. From C. nigoni mothers, F1 adult females are viable and fertile, F1 males are viable but sterile. In crosses that utilize C. nigoni males and C. briggsae hermaphrodites produce viable adult F1 females but F1 males arrest during embryogenesis. A mutation in the Cbr-him-8 gene is a recessive maternal-effect suppressor of male-specific lethality. Hybrid crosses with cbr-him-8 mutant mothers produce viable adult male progeny. The HIM-8 protein in C. elegans is required for the pairing of X-chromosomes during meiosis. This function is …

Arts & Sciences Faculty Publications
Bacterial symbionts are integral to the health and homeostasis of invertebrate hosts. Notably, members of the Rickettsiales genus Wolbachia influence several aspects of the fitness and evolution of their terrestrial hosts, but few analogous partnerships have been found in marine systems. We report here the genome, phylogenetics, and biogeography of a ubiquitous and novel Rickettsiales species that primarily associates with marine organisms. We previously showed that this bacterium was found in scleractinian corals, responds to nutrient exposure, and is associated with reduced host growth and increased mortality. This bacterium, like other Rickettsiales, has a reduced genome indicative of a parasitic …
Structural Characterization Of Black Widow Spider Dragline Silk Proteins Crp1 And Crp4, Mikayla Shanafelt
Structural Characterization Of Black Widow Spider Dragline Silk Proteins Crp1 And Crp4, Mikayla Shanafelt
University of the Pacific Theses and Dissertations
Spider dragline silk is a biomaterial with outstanding material properties, possessing high-tensile strength and toughness. In nature, dragline silk serves a central role during spider locomotion and web construction. Today, scientists are racing to elucidate the molecular machinery governing silk extrusion, attempting to translate this knowledge into a mimicry process in the laboratory to create synthetic fibers for a wide range of different applications. During extrusion, it has been established that biochemical and mechanical forces govern spidroin folding, aggregation, and assembly. In black widow spiders, at least 7 different proteins have been identified as constituents of dragline silk fibers. These …
