Chemical Attraction Of Dermacentor Variabilis Ticks Parasitic To Peromyscus Leucopus Based On Host Body Mass And Sex, Tad Dallas, Stephanie Foré

Faculty Publications

Macroparasites are commonly aggregated on a small subset of a host population. Previous explanations for this aggregation relate to differences in immunocompetence or the degree to which hosts encounter parasites. We propose active tick host choice through chemical attraction as a potential mechanism leading to aggregated tick burdens. We test this hypothesis using a Y-maze olfactometer, comparing chemical attraction responses of larval and nymphal Dermacentor variabilis ticks parasitic to the white-footed mouse, Peromyscus leucopus, as a function of host sex and host body mass. We hypothesized that larger hosts and male hosts would be most attractive to searching ticks, as …

Social Descent With Territory Loss Causes Rapid Behavioral, Endocrine And Transcriptional Changes In The Brain, Karen P. Maruska, Lisa Becker, Anoop Neboori, Russell D. Fernald

Faculty Publications

In social species that form hierarchies where only dominant males reproduce, lower-ranking individuals may challenge higherranking ones, often resulting in changes in relative social status. How does a losing animal respond to loss of status? Here, using the African cichlid fish Astatotilapia burtoni, we manipulated the social environment, causing males to descend in rank, and then examined changes in behavior, circulating steroids and immediate early gene (IEG) expression (cfos, egr-1) in micro-dissected brain regions as a proxy for neuronal activation. In particular, we examined changes in the conserved 'social behavior network' (SBN), a collection of brain nuclei known to regulate …

Silencing Histone Deacetylase-Specific Isoforms Enhances Expression Of Pluripotency Genes In Bovine Fibroblasts, Jaroslaw Staszkiewicz, Rachel A. Power, Lettie L. Harkins, Christian W. Barnes, Karen L. Strickler, Jong S. Rim, Kenneth R. Bondioli, Kenneth J. Eilersten

Faculty Publications

Histone deacetylases (HDACs) catalyze deacetylation of histones that results in altered transcriptional activity. Inhibitors of HDACs have been shown to induce transcriptional changes that contribute positively to reprogramming somatic cells either by nuclear transfer or inducing a pluripotent state. However, the exact molecular mechanisms whereby HDAC inhibitors function and the specificity of the HDAC isoforms in cell reprogramming are not yet fully understood. Herein, we report the ability of individual isoform-specific HDACs to modulate endogenous expression of pluripotency-associated genes in bovine somatic cells. This in vitro study showed that a transient selective depletion of HDACs resulted in elevated mRNA levels …

Oh My Plant: A Creative Design For Building Emotional Relationships Between People And Plants, Boran Song

Theses

While speaking with plant owners, I realized that one of the main reasons why people's plants were dying was that people lacked emotional relationships with their plants. In creating Oh My Plant, I wanted to help busy people to easily improve their gardening skills and to create an emotional relationship between people and their houseplants.

When our lives become busy and stressful, it is easy to forget to take care of our own bodies, let alone our houseplants. Yet houseplants offer numerous benefits to people, beautifying the environment and purifying the air.

I believe that the design for Oh My …

Calculating Energy Consumption For Building Materials, G. Antons, M. Hoover, W. Uebelacker, Sergio Palleroni, Huafen Hu, Ben Deines

Research-Based Design Initiative

Sustainability is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. With that, Life Cycle Assesment (LCA) was born and is now a standard tool in measuring how sustainable we are in building from material extraction to end of life.

Architects have adopted the responsibility to lead the building industry down a green and sustainable path; as a part of this, many architecture firms have expanded their practices to include studios that work specifically on green buildings or green energy audits for clients. Throughout history sustainable design has used …

Access To Civil & Family Justice: A Roadmap For Change, Action Committee On Access To Justice In Civil And Family Matters

Canadian Forum on Civil Justice

There is a serious access to justice problem in Canada. The civil and family justice system is too complex, too slow and too expensive. It is too often incapable of producing just outcomes that are proportional to the problems brought to it or reflective of the needs of the people it is meant to serve. While there are many dedicated people trying hard to make it work and there have been many reform efforts, the system continues to lack coherent leadership, institutional structures that can design and implement change, and appropriate coordination to ensure consistent and cost effective reform. Major …

Triacylglycerol Mobilization Is Suppressed By Brefeldin A In Chlamydomonas Reinhardtii, Naohiro Kato, Trung Dong, Michael Bailey, Tony Lum, Drury Ingram

Faculty Publications

Brefeldin A suppresses vesicle trafficking by inhibiting exchange of GDP for GTP in ADP-ribosylation factor. We report that brefeldin A suppresses mobilization of triacylglycerols in Chlamydomonas reinhardtii, a model organism of green microalgae. Analyses revealed that brefeldin A causes Chlamydomonas to form lipid droplets in which triacylglycerols accumulate in a dose-dependent manner. Pulse labeling experiment using fluorescent fatty acids suggested that brefeldin A inhibits the cells from degrading fatty acids. The experiment also revealed that the cells transiently form novel compartments that accumulate exogenously added fatty acids in the cytoplasm, designated fatty acid-induced microbodies (FAIMs). Brefeldin A up-regulates the formation …

Homologous Rig-I-Like Helicase Proteins Direct Rnaimediated Antièiral Immunity In C. Elegans By Distinct Mechanisms, Xunyang Guo, Rui Zhang, Jeffrey Wang, Shou Wei Ding, Rui Lu

Faculty Publications

RNAi-mediated antièiral immunity in Caenorhabditis elegans requires Dicer-related helicase 1 (DRH-1), which encodes the helicase and C-terminal domains homologous to the mammalian retinoic acid inducible gene I (RIG-I)-like helicase (RLH) family of cytosolic immune receptors. Here we show that the antièiral function of DRH-1 requires the RIG-I homologous domains as well as its wormspecific N-terminal domain. We also demonstrate that the helicase and C-terminal domains encoded by either worm DRH-2 or human RIG-I can functionally replace the corresponding domains of DRH-1 to mediate antièiral RNAi in C. elegans. Notably, substitutions in a three-residue motif of the C-terminal regulatory domain of …

Static Saliency Vs. Dynamic Saliency: A Comparative Study, Tam Nguyen, Mengdi Xu, Guangyu Gao, Mohan Kankanhalli, Qi Tian, Shuicheng Yan

Computer Science Faculty Publications

Recently visual saliency has attracted wide attention of researchers in the computer vision and multimedia field. However, most of the visual saliency-related research was conducted on still images for studying static saliency. In this paper, we give a comprehensive comparative study for the first time of dynamic saliency (video shots) and static saliency (key frames of the corresponding video shots), and two key observations are obtained: 1) video saliency is often different from, yet quite related with, image saliency, and 2) camera motions, such as tilting, panning or zooming, affect dynamic saliency significantly.

Motivated by these observations, we propose a …

Selling Art: An Empirical Assessment Of Advertising On Fertility Clinics' Websites, Jim Hawkins

Indiana Law Journal

Scholarship on assisted reproductive technologies (ART) has emphasized the commercial nature of the interaction between fertility patients and their physicians, but little attention has been paid to precisely how clinics persuade patients to choose their clinics over their competitors’. This Article offers evidence about how clinics sell ART based on clinics’ advertising on their websites. To assess clinics’ marketing efforts, I coded advertising information on 372 fertility clinics’ websites. The results from the study confirm some suspicions of prior ART scholarship while contradicting others. For instance, in line with scholars who are concerned that racial minorities face barriers to accessing …

“Undetected, Unsuspected, And Unknown”: Should We Anticipate Problems For Scientific Innovation Following Schering Corp. V. Geneva Pharmaceuticals?, Jeffrey Coleman

Fordham Law Review

    Once termed the “metaphysics” of patent law, the doctrine of inherent anticipation has befuddled courts and practitioners alike for decades. Inherent anticipation refers to the notion that a previously published reference can disclose each and every limitation of a later–patented invention without expressly delineating those limitations. These (un)disclosed limitations are necessarily present, or inherent, within the previously published reference. When a previously published reference discloses a later–claimed invention expressly or inherently, the patent covering the later–claimed invention is invalid because the invention lacks novelty. Thus, the doctrine of inherent anticipation allows invalidation of a patent in whole or in part …

Altered Cholesterol Metabolism In Human Cancers Unraveled By Label-Free Spectroscopic Imaging, Shuhua Yue

Open Access Dissertations

Despite tremendous scientific achievements, cancer remains the second leading cause of death in the United States. Metabolic reprogramming has been increasingly recognized as a core hallmark of cancer. My dissertation work identified novel diagnostic markers and therapeutic targets for human cancers through the study of cholesterol in cancer cells.

Enabled by label-free Raman spectromicroscopy, we performed the first quantitative analysis of lipogenesis at single cell level in human patient cancerous tissues. Our imaging data revealed an unexpected, aberrant accumulation of esterified cholesterol in lipid droplets of high-grade prostate cancer and metastases, but not in normal prostate, benign prostatic hyperplasia, or …

Nitrogen And Potassium Dynamics Of Selected Indiana Soils, Chun Zhao

Open Access Dissertations

Nitrogen (N) is the most limiting essential nutrient for crop growth. Numerous studies have been performed to improve N fertilizer recommendations. Accurate prediction of soil N supply has been found to be one of the most important factors that determine optimum fertilizer N rates. Seven soils collected from various locations across Indiana at four different depths were tested for N mineralization potential. Results showed that laboratory mineralizable N in the top layer (0-15 cm) of the seven soils ranged from 50 to 68 mg N kg-1 soil. In addition, more than 50% of the total mineralizable N was contributed from …

The City In Mind: Environmental Literacy And Adaptation In Nineteenth-Century British Literature, Adam Edward Watkins

Open Access Dissertations

This dissertation argues that a new paradigm of selfhood emerged in nineteenth-century British literature, one that recognized the individual will and environmental influence not as antithetical but as dialectical forces in the formation of the self. The concept of an externally negotiated subject challenges both the inward and socially determined conceptions of self that have dominated the relevant criticism. Informed by empiricist, associationist, and evolutionary theories of the mind, the portrayals of subject-formation in this study highlight the radical changes occurring in the human environment in nineteenth-century, which catalyzed the conception of a malleable yet self-forming subject. Along with the …

Effects Of Dip-Coated Films On The Properties Of Implantable Intracortical Microelectrodes, Salah Sommakia

Open Access Dissertations

The successful clinical use of implantable intracortical microelectrodes (ICMs) to treat certain types of deafness, blindness, and paralysis is limited by a reactive tissue response (RTR) of the brain. This RTR culminates in the formation of a tight glial scar and a loss of neuronal density around implanted ICMs, and is accompanied by a decrease in signal to noise ratio and an increase in impedance. While no comprehensive mechanistic understanding of the underlying biology is currently agreed upon in the field, a general consensus exists around a highly volatile acute RTR phase. During this acute phase, the electrical properties of …

Dynamic Behavior Of Sandwich Beams With Internal Resonators, Bhisham Nar Narain Sharma

Open Access Dissertations

Dynamic behavior of sandwich beams with internal resonators was investigated. The effect of inserting spring-mass resonators into the sandwich core was theoretically analyzed and it was shown that a wave attenuation bandgap exists due to local resonance. Steady state experiments were used to demonstrate such an attenuation bandgap. Frequency response functions were obtained for a beam with resonators and without resonators. It was shown that insertion of resonators into the core causes a wave attenuation bandgap to open up. The experimental results were verified using finite element simulations. Further experiments were carried out by tuning the resonators at 12 Hz …

Impacts And Feasibility Of The Us And The Eu Sustainability Criteria On Existing Land-Use Practices, Krissana Treesilvattanakul

Open Access Dissertations

Several studies have examined the land use and economic consequences of national and multi-national biofuel policies. They explored the impacts of biofuels mandates mainly based on the quantitative biofuel targets. However, the recently updated renewable policies of the United States and the European Union, which are the US Renewable Fuel Standard (RFS) and EU Directive 2009/28 of the Renewable Energy Directive (RED) both place restrictions on land that can be used to produce biofuel, and these restrictions are generally known as sustainability criteria. This research aims to determine to what extent sustainability criteria are actually binding; that is, would they …

Effects Of Amur Honeysuckle (Lonicera Maackii [Rupr.] Herder) Invasion And Removal On Native Vegetation And White-Footed Mice (Peromyscus Leucopus) In Mixed-Hardwood Forests Of Indiana, Joshua Michael Shields

Open Access Dissertations

The threat of non-native invasive species continues to compromise the ecological and economic integrity of our natural resources. Numerous investigators have documented the negative effects of invasive species on native biota. However, much work is still needed with regard to how invasive species spread in space and time, factors contributing to impacts on native biota within invaded ecosystems, and resultant effects of removing invasive species. In terms of invasion patterns, few studies have documented local patterns and rates of woody plant invasions, and even less is known about changes in spatial patterning and factors influencing structural characteristics (diameter and height) …

The Chemistry Of Flavonoids In Model Beverages And Human Milk, Brian Jay Song

Open Access Dissertations

Interest in the chemistry and stability of flavonoids in foods has been generated by countless epidemiological, in vitro, and in vivo studies that suggest a variety of potential health promoting effects of diets rich in flavonoids. Flavonoids have been shown to interact with multiple components in beverages including macromolecules, minerals, certain vitamins, and other flavonoids. Furthermore, environmental conditions including light exposure, elevated temperatures, and relative humidity have been shown to modify flavonoid stability. However, specific mechanisms, relative kinetics of degradation reactions and the impact of macromolecules in model beverages and biological fluids on flavonoid stability remain largely unknown.

Recently, interest …
