Nitrogen Cycling Responses To Mountain Pine Beetle Disturbance In A High Elevation Whitebark Pine Ecosystem, Megan P. Keville, Sasha C. Reed, Cory C. Cleveland

Ecosystem and Conservation Sciences Faculty Publications

Ecological disturbances can significantly affect biogeochemical cycles in terrestrial ecosystems, but the biogeochemical consequences of the extensive mountain pine beetle outbreak in high elevation whitebark pine (WbP) (Pinus albicaulis) ecosystems of western North America have not been previously investigated. Mountain pine beetle attack has driven widespread WbP mortality, which could drive shifts in both the pools and fluxes of nitrogen (N) within these ecosystems. Because N availability can limit forest regrowth, understanding how beetle-induced mortality affects N cycling in WbP stands may be critical to understanding the trajectory of ecosystem recovery. Thus, we measured above- and belowground N …

Green Tea Polyphenols And Sulfasalazine Have Parallel Anti-Inflammatory Properties In Colitis Models, Helieh S. Oz, Theresa Chen, Willem J.S. De Villiers

Internal Medicine Faculty Publications

Background: There is no cure for autoimmune chronic inflammatory bowel disease (IBD). IBD patients commonly use complementary and alternative medications of which the safety, efficacy, and interaction with standard-of-care therapies are not fully known. Thus the consequences can become life-threatening. Sulfasalazine commonly used in IBD, potentially has severe adverse effects, including infertility, pulmonary fibrosis, lack of response, and ultimately patients may require intestinal resection. We hypothesized that green tea polyphenols (GrTP, EGCG) and sulfasalazine have similar anti-inflammatory properties.

Adaptation To The U.S. And Religion/Spirituality: Experiences Of Indian International Students, Kirti Potkar

Theses and Dissertations

Religion and spirituality are deemed an important aspect of human diversity, found to be important to people, and have significant impact on different aspects of functioning. Given the rising numbers of international students on U.S. campuses, it becomes important to examine how religion/spirituality impacts their sojourn in the U.S. This study explored the religious/spiritual experiences of Indian international students here in the U.S. using a qualitative approach. Thirteen Indian international students pursuing graduate degrees in the U.S. were interviewed. The interviews were then transcribed and analyzed using a synthesis of hermeneutic methods informed by Kvale (1996). The following themes emerged …

The Role Of Psycho-Sociocultural Factors In Suicide Risk Among Mong/Hmong Youth, Tangjudy Vang

Dissertations and Theses

This study examined psychological, social, and cultural factors that can affect suicide risk among Mong/Hmong youth between the ages of 18 and 25. Emerging evidence suggests that Mong/Hmong youth are at an increased risk for suicide (Huang, Lee, & Arganza, 2004; Jesilow & Xiong, 2007). Additionally, initial findings and theories have suggested potential associations between Mong/Hmong youth suicide risk and intergenerational family conflict, ethnic identity, acculturation, depression, and spirituality. The seriousness of suicide risk among Mong/Hmong youth in this country has been overlooked for decades; therefore, the purpose of this study was to examine these associations with the hope that …

Integration Technologies For Implantable Microsystems, Dean Johnson

Theses

Microsystems targeted for implantation require careful consideration of power, thermals, size, reliability, and biocompatibility. The presented research explored appropriate integration technologies for an implantable drug delivery system suitable for use in mice weighing less than 20 grams. Microsystems technology advancements include in situ pump diaphragm formation; integrated, low volume microfluidic coupling technologies; and incorporation of a low voltage, low-power pump actuation with a zero-power off state. Utility of the developed integration technologies have been tested through in vitro reliability and validation experiments. A four-chamber peristaltic pump was created using micromachining (e.g. thin film deposition and Si etching) and direct write …

Does Size Matter? Scaling Of Co2 Emissions And U.S. Urban Areas, Michail Fragkias, José Lobo, Deborah Strumsky, Karen C. Seto

Economics Faculty Publications and Presentations

Urban areas consume more than 66% of the world’s energy and generate more than 70% of global greenhouse gas emissions. With the world’s population expected to reach 10 billion by 2100, nearly 90% of whom will live in urban areas, a critical question for planetary sustainability is how the size of cities affects energy use and carbon dioxide (CO₂) emissions. Are larger cities more energy and emissions efficient than smaller ones? Do larger cities exhibit gains from economies of scale with regard to emissions? Here we examine the relationship between city size and CO₂ emissions for U.S. …

Germline Transgenic Methods For Tracking Cells And Testing Gene Function During Regeneration In The Axolotl, Shahryar Khattak, Maritta Schuez, Tobias Richter, Dunja Knapp, Saori L. Haigo, Tatiana Sandoval-Guzmán, Kristyna Hradlikova, Annett Duemmler, Ryan R. Kerney, Elly M. Tanaka

Biology Faculty Publications

The salamander is the only tetrapod that regenerates complex body structures throughout life. Deciphering the underlying molecular processes of regeneration is fundamental for regenerative medicine and developmental biology, but the model organism had limited tools for molecular analysis. We describe a comprehensive set of germline transgenic strains in the laboratory-bred salamander Ambystoma mexicanum(axolotl) that open up the cellular and molecular genetic dissection of regeneration. We demonstrate tissue-dependent control of gene expression in nerve, Schwann cells, oligodendrocytes, muscle, epidermis, and cartilage. Furthermore, we demonstrate the use of tamoxifen-induced Cre/loxP-mediated recombination to indelibly mark different cell types. Finally, we inducibly …

Lipid Nature And Their Influence On Opening Of Redox-Active Liposomes, Martin Loew, Jerimiah C. Forsythe, Robin L. Mccarley

Faculty Publications

The pathway for content release from reduction-sensitive liposomes based on a quinone-dioleoylphosphatidylethanolamine lipid conjugate (Q-DOPE) is outlined using results from fluorescent dye content release assays as well as single- and multiple-angle light scattering. Experimental observations are consistent with a shape/size change of the reduced liposomes prior to their aggregation, with subsequent near-quantitative content release achieved only when the lipid membrane experiences conditions favorable to a lamellar to an inverted hexagonal phase transition. Addition of poly(ethyleneglycol)-modified DOPE (PEG-DOPE) to the Q-DOPE liposomal formulation results in stabilization of the lipid bilayer, whereas incorporation of DOPE yields faster content release. At high DOPE …

Halogen Photoelimination From Dirhodium Phosphazane Complexes Via Chloride-Bridged Intermediates, David C. Powers, Matthew B. Chambers, Thomas S. Teets, Noémie Elgrishi, Bryce L. Anderson, Daniel G. Nocera

Faculty Publications

Halogen photoelimination is a critical step in HX-splitting photocatalysis. Herein, we report the photoreduction of a pair of valence-isomeric dirhodium phosphazane complexes, and suggest that a common intermediate is accessed in the photochemistry of both mixed-valent and valence-symmetric complexes. The results of these investigations suggest that halogen photoelimination proceeds by two sequential photochemical reactions: ligand dissociation followed by subsequent halogen elimination. © 2013 Royal Society of Chemistry.

Method To Facilitate Directed Delivery And Electroporation Using A Charged Stream, Mark Jaroszeski, Gabriel A. Lopez-Diaz, Richard J. Connolly, Andrew M. Hoff

USF Patents

A method for facilitating a delivery of a molecule into an interior space of a cell includes the steps of introducing a molecule into a biological structure comprising a cell and applying a substantially continuous low-level electric field, in the form of non-thermal plasma (ionized gas) generated by a direct current voltage applied to an electrode, to the molecule and biological structure. The field is applied for a duration sufficient to effect a change in porosity the cell of the biological structure sufficient to facilitate an entry of a desired molecule into an interior thereof.

Oil-Source Rock Correlation In The Late Paleozoic, Denver Basin, Nebraska: The Search For A Negative Δ¹³C Anomaly In Pennsylvanian–Permian Cyclothems, John P. Still

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Late Paleozoic sedimentation in the Denver basin occurred in two environmentally distinct depocenters. The northern-most Alliance Basin has been interpreted to have a restricted character: anhydrite-bearing mudstones are present in cyclothems comprising wackestone, packstone and mudstone. The source of petroleum produced from these intervals is considered to be organic-rich units within these cyclothems. Oil recovered from late Paleozoic reservoirs has δ13C values that range from -30.8‰ to -28.8‰: values that are lower than those reported previously for prospective source rocks from this interval. Cores from seven wells that penetrate upper Pennsylvanian to lower Permian rocks have been chosen for analysis. …

Lack Of Variation At Phosphoglucose Isomerase (Pgi) In Bumblebees: Implications For Conservation Genetics Studies, Jonathan S. Ellis, Lucy M. Turner, Mairi E. Knight

School of Biological and Marine Sciences

Assessing genetic variation underlying ecologically important traits is increasingly of interest and importance in population and conservation genetics. For some groups generally useful markers exist for examining the relative role of selection and drift in shaping genetic diversity e.g. the major histocompatibility complex in vertebrates and self-incompatibility loci in plants. For invertebrates there is no such generally useful locus. However, phosphoglucose isomerase (Pgi) has been proposed as a useful functional marker in the conservation genetics of invertebrates. Where thermal microclimate varies, balanced polymorphisms may be maintained due to trade-offs between thermally stable and kinetically advantageous allelic forms. We here report …

Micu1 Controls Both The Threshold And Cooperative Activation Of The Mitochondrial Ca(2+) Uniporter., György Csordás, Tünde Golenár, Erin L Seifert, Kimberli J Kamer, Yasemin Sancak, Fabiana Perocchi, Cynthia Moffat, David Weaver, Sergio De La Fuente Perez, Roman Bogorad, Victor Koteliansky, Jeffrey Adijanto, Vamsi K Mootha, György Hajnóczky

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Mitochondrial Ca(2+) uptake via the uniporter is central to cell metabolism, signaling, and survival. Recent studies identified MCU as the uniporter's likely pore and MICU1, an EF-hand protein, as its critical regulator. How this complex decodes dynamic cytoplasmic [Ca(2+)] ([Ca(2+)]c) signals, to tune out small [Ca(2+)]c increases yet permit pulse transmission, remains unknown. We report that loss of MICU1 in mouse liver and cultured cells causes mitochondrial Ca(2+) accumulation during small [Ca(2+)]c elevations but an attenuated response to agonist-induced [Ca(2+)]c pulses. The latter reflects loss of positive cooperativity, likely via the EF-hands. MICU1 faces the intermembrane space and responds to …

Seeing Crucibles: Legitimizing Spiritual Development In The Middle Grades Through Critical Historiography, Audrey Lingley

Dissertations and Theses

Advocates of middle grades reform in the United States argue that curriculum and instruction, as well as leadership, organization, and community relationships, should be informed by knowledge of the developmental characteristics of 10 to 15 year-olds within physical, social, emotional, psychological, cognitive, and moral domains. Noticeably absent from their conception of human development are spiritual developmental characteristics of young adolescents.

This interdisciplinary research was a critical constructivist (Kincheloe, 2008) inquiry of the following question: What is the educational relevance of spiritual development in middle grades education? To study this question, critical historiographical research methods (Villaverde, Kincheloe, & Helyar, 2006) were …

The Queer Truth, Chelsea E. Broe

SURGE

I remember learning about intersexuality (then called hermaphrodism) for the first time in my health class when I was twelve years old. In that lesson, my teacher mentioned that when a child is born intersex, the parents will likely choose a binary sex (male or female) for the child, have the child undergo sex reassignment surgery, and raise the child to fit the corresponding gender. My teacher went on to explain that sometimes the parents pick the “wrong” sex for their child, and the child grows up feeling like he or she should be the “opposite” gender. Implied in this …

Prevalence And Characterization Of Verotoxigenic-Escherichia Coli Isolates From Pigs In Malaysia, Wing Sze Ho, Lai Kuan Tan, Peck Toung Ooi, Chew Chieng Yeo, Kwai Lin Thong

Research Publications (2011 to 2015)

Background: Postweaning diarrhea caused by pathogenic Escherichia coli, in particular verotoxigenic E. coli (VTEC), has caused significant economic losses in the pig farming industry worldwide. However, there is limited information on VTEC in Malaysia. The objective of this study was to characterize pathogenic E. coli isolated from post-weaning piglets and growers with respect to their antibiograms, carriage of extended-spectrum beta-lactamases, pathotypes, production of hemolysins and fimbrial adhesins, serotypes, and genotypes. Results: PCR detection of virulence factors associated with different E. coli pathotypes (ETEC, EPEC, EHEC, and VTEC) revealed that VTEC was the only pathotype identified from six swine farms located …

A Comparison Of 100 Human Genes Using An Alu Element-Based Instability Model, George W. Cook, Miriam K. Konkel, Jerilyn A. Walker, Matthew G. Bourgeois, Mitchell L. Fullerton, John T. Fussell, Heath D. Herbold, Mark A. Batzer

Faculty Publications

The human retrotransposon with the highest copy number is the Alu element. The human genome contains over one million Alu elements that collectively account for over ten percent of our DNA. Full-length Alu elements are randomly distributed throughout the genome in both forward and reverse orientations. However, full-length widely spaced Alu pairs having two Alus in the same (direct) orientation are statistically more prevalent than Alu pairs having two Alus in the opposite (inverted) orientation. The cause of this phenomenon is unknown. It has been hypothesized that this imbalance is the consequence of anomalous inverted Alu pair interactions. One proposed …

The Effects Of Exposure To Violence And Victimization Across Life Domains On Adolescent Substance Us, Emily M. Wright, Abigail A. Fagan, Gillian M. Pinchevsky

Criminology and Criminal Justice Faculty Publications

This study uses longitudinal data from the Project on Human Development in Chicago Neighborhoods (PHDCN) to examine the effects of exposure to school violence, community violence, child abuse, and parental intimate partner violence (IPV) on youths’ subsequent alcohol and marijuana use. We also examine the cumulative effects of being exposed to violence across these domains. Longitudinal data were obtained from 1,655 adolescents and their primary caregivers participating in the PHDCN. The effects of adolescents’ exposure to various forms of violence across different life domains were examined relative to adolescents’ frequency of alcohol and marijuana use three years later. Multivariate …
