The Effects Of Prenatal Exposure To Altered Melatonin Levels On Hippocampal Gene Expression In The Male Rat, Anna Uehara

Honors Theses

The stability of the circadian rhythm for mammals depends on the levels of serotonin and melatonin, neurohormones that signal for lightness and darkness, respectively. Disruption in the stability of neurohormones has been shown to be a critical factor in psychopathological disorders in humans. For example, altering levels of melatonin in utero through administration of melatonin or the melatonin receptor antagonist, luzindole, has been shown to cause changes in developmental growth and adult behavior in the male rat. Analysis of relative adult hippocampal gene expression with RT-PCR revealed differences in ARNTL expression that suggested abnormality in clock gene expression of the …

Rapid Spread Of Tomato Yellow Leaf Curl Virus In China Is Aided Differentially By Two Invasive Whiteflies, Huipeng Pan, Dong Chu, Wenqian Yan, Qi Su, Baiming Liu, Shaoli Wang, Qingjun Wu, Wen Xie, Xiaoguo Jiao, Rumei Li, Nina Yang, Xin Yang, Baoyun Xu, Judith K. Brown, Xuguo Zhou, Youjun Zhang

Entomology Faculty Publications

BACKGROUND: Tomato yellow leaf curl virus (TYLCV) was introduced into China in 2006, approximately 10 years after the introduction of an invasive whitefly, Bemisia tabaci (Genn.) B biotype. Even so the distribution and prevalence of TYLCV remained limited, and the economic damage was minimal. Following the introduction of Q biotype into China in 2003, the prevalence and spread of TYLCV started to accelerate. This has lead to the hypothesis that the two biotypes might not be equally competent vectors of TYLCV.

METHODOLOGY/PRINCIPAL FINDINGS: The infection frequency of TYLCV in the field-collected B. tabaci populations was investigated, the acquisition and transmission …

Deletion Of Foxn1 In The Thymic Medullary Epithelium Reduces Peripheral T Cell Responses To Infection And Mimics Changes Of Aging, Jianfei Guo, Yan Feng, Peter Barnes, Fang-Fang Huang, Steven Idell, Dong-Ming Su, Homayoun Shams

School of Medicine Faculty Publications and Presentations

Aging increases susceptibility to infection, in part because thymic involution culminates in reduced naïve T-lymphocyte output. Thymic epithelial cells (TECs) are critical to ensure normal maturation of thymocytes and production of peripheral T cells. The forkhead-class transcription factor, encoded by FoxN1, regulates development, differentiation, and function of TECs, both in the prenatal and postnatal thymus. We recently showed that expression of FoxN1, by keratin 14 (K14)-expressing epithelial cells is essential for maintenance of thymic medullary architecture, and deletion of FoxN1 in K14 promoter-driven TECs inhibited development of mature TECs and reduced the number of total thymocytes. These findings are reminiscent …

Protein Synthesis Factors (Rf1, Rf2, Rf3, Rrf, And Tmrna) And Peptidyl-Trna Hydrolase Rescue Stalled Ribosomes At Sense Codons., Serafín Vivanco-Domínguez, José Bueno-Martínez, Gloria León-Avila, Nobuhiro Iwakura, Akira Kaji, Hideko Kaji, Gabriel Guarneros

Department of Biochemistry and Molecular Biology Faculty Papers

During translation, ribosomes stall on mRNA when the aminoacyl-tRNA to be read is not readily available. The stalled ribosomes are deleterious to the cell and should be rescued to maintain its viability. To investigate the contribution of some of the cellular translation factors on ribosome rescuing, we provoked stalling at AGA codons in mutants that affected the factors and then analyzed the accumulation of oligopeptidyl (peptides of up to 6 amino acid residues, oligopep-)-tRNA or polypeptidyl (peptides of more than 300 amino acids in length, polypep-)-tRNA associated with ribosomes. Stalling was achieved by starvation for aminoacyl-tRNA(Arg4) upon induced expression of …

Workplace Discrimination And The Perception Of Disability, William Draper

Theses and Dissertations

Decisions by the EEOC in favor of claimants perceived to have disabilities disproportionately exceeded those in favor of claimants with documented disabilities. This finding lends support to the assertion that unconscious/implicit bias is persistent in the workplace.

Hiv/Sti Risk Factors Among African-American Students Attending Predominantly White Universities, Marya L. Shegog, Lisa Lindley, Melva Thompson-Robinson, David Simmons, Donna Richter

Journal of Health Disparities Research and Practice

Introduction: The majority of African American college students in the U.S. attend predominantly white institutions (PWIs). However, there is minimal research examining this population’s HIV/STI risk behaviors. The purpose of this investigation was to assess HIV/STI behavioral risk factors among African American college students (aged 18 – 24years) attending PWIs. (n = 2,568)

Methods: Backwards step-wise logistic regression analyses were conducted to determine factors associated with a positive HIV/STI diagnosis (past year) among sexually active African American college students who participated in the Spring, 2006 National College Health Assessment.

Findings: Nine factors were significantly associated with an HIV/STI diagnosis among …

Prioritizing Interventions And Research To Address The Cancer Disparities Of Arizona’S American Indian Population, Norman J. Petersen, Sujata Joshi, Tim Flood, Kathryn Coe

Journal of Health Disparities Research and Practice

The aim of the Southwest American Indian Collaborative Network (SAICN) is to reduce cancer disparities by closing the gap between community needs and the promise of cancer prevention and cure through participatory education, training and research programs. In an effort to provide evidence-based recommendations and promote the use of relevant data in tribal communities, the SAICN Data and Evaluation Core developed two comparison matrices that present scientifically sound practices for use by community health decision makers in prioritizing activities likely to reduce the irrespective community’s burden of cancer. In their current configurations, Matrix A considers those cancers for which prevention …

Application Of The Pen-3 Model In A Diabetes Prevention Intervention, Joan E. Cowdery, Shandowyn Parker, Amy Thompson

Journal of Health Disparities Research and Practice

More effective strategies for addressing health issues in African American communities are needed. As part of a three year NIH funded Project Export grant, this community campus partnership used community-based participatory research principles and thePEN-3 Cultural Framework to develop a culturally specific, locally relevant intervention to prevent Diabetes among African-Americans. A comprehensive needs assessment which included 13 elicitation interviews, 3 focus groups, and 217 surveys resulted in identifying major themes including overall lack of knowledge regarding Diabetes,issues of denial and stigma, sense of inevitability, influence of family on perceptionsand behaviors, communication issues with health care providers, and lack of culturally …

Eelgrass Habitat Creation In Nantucket Harbor, Massachusetts, David M. Burdick, Gregg Moore, Chris Peter

Natural Resources & the Environment

In response to eelgrass habitat losses associated with development and marine activities in and around Nantucket Harbor, a plan to restore a meadow by transplanting eelgrass to previously vegetated areas was developed in conjunction with the Nantucket Land Council. Over 6,000 eelgrass shoots were sustainably harvested from an extensive bed within the Harbor that was located just west of First Point and near the inlet to Nantucket Sound. Four weeks following collection, impacts from our collection were shown by a 24% decline in shoot density, but live eelgrass cover did not decline significantly. After 12 weeks, no effects of collecting …

Leaf Area And Structural Changes After Thinning In Even-Aged Picea Rubens And Abies Balsamea Stands In Maine, Usa, R. Justin Derose, Robert S. Seymour

Wildland Resources Faculty Publications

We tested the hypothesis that changes in leaf area index (LAI m2 m−2) and mean stand diameter following thinning are due to thinning type and residual density. The ratios of pre- to postthinning diameter and LAI were used to assess structural changes between replicated crown, dominant, and low thinning treatments to 33% and 50% residual density in even-aged Picea rubens and Abies balsamea stands with and without a precommercial thinning history in Maine, USA. Diameter ratios varied predictably by thinning type: low thinnings were 0.7 but 1.0 . LAI change was affected by type and intensity of thinning. On average, …

School Culture: A Sequential Mixed Methods Exploratory Meta-Analysis, Cynthia Pritchett

Theses and Dissertations

This multi-national study used systematic review as a data collection technique to determine the current field of empirical studies that posit a definition of school culture and its characteristics. The data gathered from a qualitative synthesis and analysis of the acquired studies informed school culture taxonomy. The taxonomy presented domains, classes, categories, characteristics, and elements, which became the variables for meta-analysis. This adapted methodological process resulted in a valid and generalizable definition of school culture. The adapted sequential mixed methods exploratory approach used in this study resulted in the generation of grounded theory. The grounded theory is a definition of …

Assessment Of New Energy Use Policy In Land Use Planning, Xun Liu

Community and Regional Planning Program: Theses

In modern society, energy has long been a part of human life. However, traditional energy resources will be used up eventually, and they also cause environmental pollution. In contrast with traditional energy resources, new energy has three major advantages: it has high efficiency, renewable and environmentally friendly. Considering new energy’s efficiency, local government should adopt appropriate policies. New energy policies are the most effective and direct method to enable governments to achieve their goals.

This study mainly focuses on how energy policies can improve the efficiency of new energy use. More specifically, this research addresses three major questions: 1) To …

Seed Mucilage Improves Seedling Emergence Of A Sand Desert Shrub, Xuejun Yang, Carol C. Baskin, Jerry M. Baskin, Guangzheng Liu, Zhenying Huang

Biology Faculty Publications

The success of seedling establishment of desert plants is determined by seedling emergence response to an unpredictable precipitation regime. Sand burial is a crucial and frequent environmental stress that impacts seedling establishment on sand dunes. However, little is known about the ecological role of seed mucilage in seedling emergence in arid sandy environments. We hypothesized that seed mucilage enhances seedling emergence in a low precipitation regime and under conditions of sand burial. In a greenhouse experiment, two types of Artemisia sphaerocephala achenes (intact and demucilaged) were exposed to different combinations of burial depth (0, 5, 10, 20, 40 and 60 …

Ionically Self-Assembled, Multi-Luminophore One-Dimensional Micro- And Nanoscale Aggregates Of Thiacarbocyanine Gumbos, Sergio L. De Rooy, Susmita Das, Min Li, Bilal El-Zahab, Atiya Jordan, Ridgely Lodes, Anna Weber, Lin Chandler, Gary A. Baker, Isiah M. Warner

Faculty Publications

Groups of uniform materials based on organic salts (GUMBOS), derived from thiacarbocyanine (TC)-based dyes with increasing methyne chain lengths, were prepared through a single-step metathesis reaction between the iodide form of the TC dye and lithium bis(perfluoroethylsulfonyl)imide as the lipophilic anion source. Ionic self-assembly of these fluorescent hydrophobic GUMBOS resulted in aqueous dispersions of one-dimensional micro- and nanoscale molecular aggregates. Blended binary and ternary aggregates containing multiple TC GUMBOS were also prepared. These nanostructures exhibited a variety of aspect ratios, affording tunable Förster resonance energy transfer (FRET) and aggregation-dependent spectroscopic properties. © 2012 American Chemical Society.
