Gut Microbiota-Derived Short-Chain Fatty Acids, T Cells, And Inflammation, Chang Kim, Jeongho Park, Myunghoo Kim

Department of Comparative Pathobiology Faculty Publications

T cells are central players in the regulation of adaptive immunity and immune tolerance. In the periphery, T cell differentiation for maturation and effector function is regulated by a number of factors. Various factors such as antigens, co-stimulation signals, and cytokines regulate T cell differentiation into functionally specialized effector and regulatory T cells. Other factors such as nutrients, micronutrients, nuclear hormones and microbial products provide important environmental cues for T cell differentiation. A mounting body of evidence indicates that the microbial metabolites short-chain fatty acids (SCFAs) have profound effects on T cells and directly and indirectly regulate their differentiation. We …

The Institutional Review Board (Irb) And Faculty: Does The Irb Challenge Faculty Professionalism In The Social Sciences?, Glenda Droogsma Musoba, Stacy A. Jacob, Leslie J. Robinson

The Qualitative Report

Institutional Review Boards (IRB) were instituted to protect the rights of research participants and due to past (and at times egregious) practices committed in the name of research. We question whether the IRB is currently overstepping its bounds into the domain of the researcher. We illustrate possible ways in which the IRB subtlety and not so subtlety challenge faculty professionalism and limit faculty research independence, highlighting some instances in which qualitative research topics bump up against boards that mistrust or misunderstand the nature of qualitative research. Using case study vignettes from five universities, our concerns focused on mission creep and …

Epigenetic Regulation Of Nuclear Hormone Receptor Dax-1, Michael B. Heskett

Master's Theses

DAX-1 (NR0B1) is an orphan nuclear receptor that plays a key role in the development and maintenance of steroidogenic tissue in mammals. Dax-1 is also expressed in mouse embryonic stem (ES) cells and is required to maintain pluripotency. Duplication of the X-chromosome in the region containing the NR0B1 gene results in sex reversal, and mutations in NR0B1 cause adrenal hypoplasia congenita. DAX-1 has been observed to act as a corepressor of other nuclear receptors including androgen receptor (AR), estrogen receptor (ER), and steroidogenic factor 1 (SF-1). In addition to pluripotent ES cells, DAX-1 is primarily expressed in select tissues of …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The need to be more environmentally conscious has recently shifted toward the forefront of society. With this new focus on environmentally responsible behavior comes the practice of using recycled materials in construction when possible. Therefore it is necessary to carefully evaluate the safety of any recycled materials being used in pavement materials. Under this study, a reference of testing is presented and implemented to test leachate of samples of two different asphalt binder types containing used motor oil (UMO) and/or crumb rubber modifier (CRM) for the presence of benzene, toluene, ethylbenzene, and xylenes (BTEX). Alongside batch leaching tests, air testing …

Commensality, Sustainability, And Restaurant Clustering In A Suburban Community, Lenore L. Newman

Suburban Sustainability

A study of a restaurant cluster on the suburban fringe of Vancouver, Canada demonstrates how commensality can play a role in the creation of more sustainable suburban environments sustainability by fostering a walkable suburban environment that encourages commensal behavior. With sixty restaurants within a few blocks of each other, the historic village of Steveston serves as an important site of social relations within the larger suburban community. Such a cluster supports the argument that commensality is an important component of the dining experience, and that the ability to eat together is a source of social capital to surrounding residents. The …

School of Natural Resources: Faculty Publications

A strong teleconnection exists between the sea surface temperature (SST) over the tropical Pacific and the winter precipitation in the southeastern United States (SE US).This feature is adopted to validate the fidelity of Coupled Model Intercomparison Project Phase 5 (CMIP5) in this study. In addition, the authors examine whether the teleconnection pattern persists in the future under a global warming scenario. Generally, most of the eight selected models show a positive correlation between November SST over Ni˜no 3 region and December–February (DJF) mean daily precipitation anomalies over the SE US, consistent with the observation. However, the models with poor realization …

The Importance Of Resistance Training In The Treatment Of Sarcopenia, Dennis Hunt, Deborah W. Chapa, Barbara Hess, Kathleen Swanick, Andrew Hovanec

Nursing Faculty Publications

Utilizing individualized exercise training programs that are inclusive of appropriate resistance training protocols can attenuate the deleterious effects of sarcopenia and enhance quality of life, functional capacity and also diminish its negative effect on independence. Nurses should be educated in how the utilization of proper resistance training (RT) in individuals can be used to ameliorate the effect of sarcopenia, especially considering its relationship to Quality of Life (QoL), functional capacity and independence. In part, this educational process should include how to refer patients to an appropriate healthcare provider trained in assessing sarcopenia and the use of resistance training. However, it …

Akagi, H. Coe, J. S. Craven, E. V. Fischer, G. R. Mcmeeking, J. H. Seinfeld, T. Soni, J. W. Taylor, D. R. Weise, C. E. Wold

Chemistry and Biochemistry Faculty Publications

Within minutes after emission, rapid, complex photochemistry within a biomass burning smoke plume can cause large changes in the concentrations of ozone (O₃) and organic aerosol (OA). Being able to understand and simulate this rapid chemical evolution under a wide variety of conditions is a critical part of forecasting the impact of these fires on air quality, atmospheric composition, and climate. Here we use version 2.1 of the Aerosol Simulation Program (ASP) to simulate the evolution of O₃ and secondary organic aerosol (SOA) within a young biomass burning smoke plume from the Williams prescribed burn in chaparral, …

A Central Support System Can Facilitate Implementation And Sustainability Of A Classroom-Based Undergraduate Research Experience (Cure) In Genomics, David Lopatto, Charles Hauser, Christopher J. Jones, Don Paetkau, Randall J. Dejong

University Faculty Publications and Creative Works

In their 2012 report, the President’s Council of Advisors on Science and Technology advocated “replacing standard science laboratory courses with discovery-based research courses”—a challenging proposition that presents practical and pedagogical difficulties. In this paper, we describe our collective experiences working with the Genomics Education Partnership, a nationwide faculty consortium that aims to provide undergraduates with a research experience in genomics through a scheduled course (a classroom-based undergraduate research experience, or CURE). We examine the common barriers encountered in implementing a CURE, program elements of most value to faculty, ways in which a shared core support system can help, and the …

Satellite Evidence For Significant Biophysical Consequences Of The “Grain For Green” Program On The Loess Plateau In China, Jingfeng Xiao

All Materials

Afforestation has been implemented worldwide as regional and national policies to address environmental problems and to improve ecosystem services. China's central government launched the “Grain for Green” Program (GGP) in 1999 to increase forest cover and to control soil erosion by converting agricultural lands on steep slopes to forests and grasslands. Here a variety of satellite data products from the Moderate Resolution Imaging Spectroradiometer were used to assess the biophysical consequences of the GGP for the Loess Plateau, the pilot region of the program. The average tree cover of the plateau substantially increased because of the GGP, with a relative …

Optimizing Data Movement In Hybrid Analytic Systems, Patrick Michael Leyshock

Dissertations and Theses

Hybrid systems for analyzing big data integrate an analytic tool and a dedicated data-management platform, storing data and operating on the data at both components. While hybrid systems have benefits over alternative architectures, in order to be effective, data movement between the two hybrid components must be minimized. Extant hybrid systems either fail to address performance problems stemming from inter-component data movement, or else require the user to explicitly reason about and manage data movement. My work presents the design, implementation, and evaluation of a hybrid analytic system for array-structured data that automatically minimizes data movement between the hybrid components. …

Servant Leadership To Toxic Leadership: Power Of Influence Over Power Of Control, David B. Ross, Rande Matteson, Julie Exposito

Faculty Presentations

To lead, you must serve. Servant leadership is the systematic process of developing the needs of servants ahead of those leaders found within private or public institutions. The principle behind effective leadership is based on the interplay of responsibility, respect, care, and working with people, not against people. Ultimately, leadership is about character and substance. Using the distinct characteristics of servant leadership to promote and foster the development of successful individuals is one of the fundamental concepts of servant leaders. Honest and caring concern for others leads to empowerment and emotional support which inspires the members to embrace the needs …

High Intralocus Variability And Interlocus Recombination Promote Immunological Diversity In A Minimal Major Histocompatibility System, Anthony B. Wilson, Camilla M. Whittington, Angela Bahr

Publications and Research

Background: The genes of the major histocompatibility complex (MHC/MH) have attracted considerable scientific interest due to their exceptional levels of variability and important function as part of the adaptive immune system. Despite a large number of studies on MH class II diversity of both model and non-model organisms, most research has focused on patterns of genetic variability at individual loci, failing to capture the functional diversity of the biologically active dimeric molecule. Here, we take a systematic approach to the study of MH variation, analyzing patterns of genetic variation at MH class IIα and IIβ loci of the seahorse, which …

The spatial variations of the gas-to-dust ratio (GDR) provide constraints on the chemical evolution and lifecycle of dust in galaxies. We examine the relation between dust and gas at 10-50 pc resolution in the Large and Small Magellanic Clouds (LMC and SMC) based on Herschel far-infrared (FIR), HI 21 cm, CO, and Hiα observations. In the diffuse atomic interstellar medium (ISM), we derive the GDR as the slope of the dust-gas relation and find GDRs of 380-130+250 ± 3 in the LMC, and 1200-420+1600 ± 120 in the SMC, not including helium. The atomic-to-molecular transition is located at dust surface …

The dust properties in the Large and Small Magellanic clouds (LMC/SMC) are studied using the HERITAGE Herschel Key Project photometric data in five bands from 100 to 500 μm. Three simple models of dust emission were fit to the observations: a single temperature blackbody modified by a power-law emissivity (SMBB), a single temperature blackbody modified by a broken power-law emissivity (BEMBB), and two blackbodies with different temperatures, both modified by the same power-law emissivity (TTMBB). Using these models, we investigate the origin of the submillimeter excess, defined as the submillimeter emission above that expected from SMBB models fit to observations …

In the SSC emission scenario, we find that the …

Linear Operators That Preserve Graphical Properties Of Matrices: Isolation Numbers, Leroy B. Beasley, Seok-Zun Song, Young Bae Jun

Mathematics and Statistics Faculty Publications

Let A be a Boolean {0, 1} matrix. The isolation number of A is the maximum number of ones in A such that no two are in any row or any column (that is they are independent), and no two are in a 2 × 2 submatrix of all ones. The isolation number of A is a lower bound on the Boolean rank of A. A linear operator on the set of m × n Boolean matrices is a mapping which is additive and maps the zero matrix, O, to itself. A mapping strongly preserves a set, S, if it …
