Bradley Faculty Fellow iv STROKE RECOVERY Allison Abellaneda, Hongwu Zeng (Mentor), Radiology Stroke is the sudden death of brain cells due to inadequate blood flow. Basal ganglia, associated with motor control, cognition, emotions, and learning, consists of the most common affected structures. This study evaluates the difference in volume of these structures between stroke patients and normal controls, and also tests correlation between volume decrease and function loss. Using images of the brain acquired through Spoiled Gradient Recalled Sequence and a program called MRIcroN, tracings of basal ganglia structures facilitate comparison between stroke patients and normal controls, to test correlation between the volume decrease and the function loss. Ultimately, we want to restore function to stroke patients by establishing a customized rehabilitation plan, so a satisfying quality of life can be experienced. HUNTING FOR FLAVIVIRUSES: DESIGNING A DIAGNOSTIC RT-PCR FOR DETECTION OF MOSQUITO INFECTIONS Axel Adams, Tony Goldberg (Mentor), Pathobiological Sciences Three-quarters of emerging diseases are zoonotic and many of these are arthropod-borne. Flaviviridae contains many important arthropod-borne viruses such as West Nile virus (WNV) and Yellow fever virus and also includes a class of recently-discovered insect-specific flaviviruses, such as Culex flavivirus (CxFV). CxFV has been shown to co-infect with WNV in Culex pipiens mosquitoes in Chicago, IL. Using RT-PCR, annual data from the field, and the knowledge that flaviviruses exhibit significant nucleotide conservation of the NS5 gene (which encodes the viral polymerase), we developed a nested set of generic RT-PCR primers for the detection of mosquito-borne flaviviruses that may be co-circulating in Chicago, IL. This should enhance the discovery of novel flaviviruses while facilitating studies of co-infection and virus ecology. CHALLENGES IN FAMILY BUSINESS Luis Aldana, Debra Holschuh-Houden (Mentor), Business Outreach When family members work together, emotions may interfere with business decisions. Conflicts may arise as relatives see the business from different perspectives. I will examine two family business Los Gemelos and Taqueria Guadalajara and look at potential problems that businessnes face. The job of family manager may be complicated by relatives who must be reconciled to working together in a business. I will conduct a survey focusing on the current issues that both family business face and recommendations to each to see where they are with their practices. There are no simple or quick solutions to the unique challenges faced by family businesses. This project will conclude with recommendations for each business to accomplish goals and provide for orderly succession. 1 MONOMERIC VS. MULTIMERIC PROPERTIES OF SWEET TASTE RECEPTOR T1R2 SUBUNIT PROTEIN Maxwell Alexander, Fariba Assadi-Porter (Mentor), Biochemistry The human taste receptor (hT1R) is composed of two subunits, hT1R2 and hT1R3, and allows the human body to detect and respond to sweet substances, including sugars and artificial sweeteners. To understand the interactions of hT1R2-T1R3 heterodimers with sweet ligands, it is necessary to express the physical properties of proteins by a heterologous expression system such as E. coli. We have expressed the hT1R2 protein in E. coli and are studying the various quaternary structural multiplicities of the protein by fast protein liquid chromatography (FPLC) gel filtration. This study aims to determine the monomeric vs. multimeric properties of the hT1R2 subunit protein through FPLC gel filtration studies and its binding properties through saturation transfer difference (STD) NMR binding assay to test for activity by binding of ligands, and whether the monomeric subunit may be analyzed through NMR spectroscopy. EARLY PREDICTORS OF TREATMENT SERVICES FOR CHILDREN WITH AUTISM SPECTRUM DISORDERS Sarah Allen, Susan Ellis Weismer (Mentor), Communicative Disorders Predictors of treatment services and educational outcomes at age 5 were examined for 103 children on the autism spectrum. Age 2 predictors included nonverbal cognition, autism severity, receptive and expressive language, maternal education, and geographic location. Service outcomes included speech and language therapy hours, intensive autism therapy, and general education placement. Maternal education and geographic location were not significantly correlated with outcome variables. Receptive language at age 2 negatively predicted participation in intensive therapy at age 5, controlling for expressive language, nonverbal cognition, and autism severity at age 2. Receptive and expressive language at age 2 predicted hours of speech and language therapy received at age 5. This research adds to the literature on treatment services and educational outcomes for children with autism spectrum disorders. PATTERNS TO POLYNOMIALS ASSOCIATED WITH PARTITIONS Ayah Almousa, Melanie Wood (Mentor), Mathematics The purpose of this research is to find a pattern to polynomials that describe certain sets of numbers called partitions. Many of these polynomials are of the form L^|p|, where |p| refers to the number of elements in the partition p, but there are many exceptions; the goal is to find an infallible pattern to the partitions with polynomials of the aforementioned form. Using Maple code, many of these polynomials are generated and analyzed; any apparent patterns are documented with the intention of being rigorously proven. The resulting patterns will help mathematicians better understand the geometry of configuration spaces, which are used in physics to describe the configurations of particles. This research has an additional application to describing the multiplicities of roots of polynomials. 2 THE INFLUENCE OF PROXIMITY TO ENVIRONMENTAL HAZARDS ON PERCEIVED RISK: A LITERATURE REVIEW Scott Andre, Dolores Severtson (Mentor), Nursing Proximity to environmental hazards, on the ground or viewed on maps, influences risk beliefs, protective behaviors and ultimately health outcomes. The influence of proximity upon risk beliefs and behavior was assessed through literature review. Overall, the relationship between proximity and risk beliefs was under-examined. Proximity to hazards had varying levels of influence on beliefs. In most studies, nearness to a hazard related to stronger risk beliefs, proximity related to weaker beliefs in several others, some showed no relation.

  • Self-Medication As Adaptive Plasticity: Increased Ingestion of Plant Toxins by Parasitized Caterpillars
    Self-Medication as Adaptive Plasticity: Increased Ingestion of Plant Toxins by Parasitized Caterpillars Michael S. Singer1*, Kevi C. Mace1, Elizabeth A. Bernays2 1 Department of Biology, Wesleyan University, Middletown, Connecticut, United States of America, 2 Department of Entomology, University of Arizona, Tucson, Arizona, United States of America Abstract Self-medication is a specific therapeutic behavioral change in response to disease or parasitism. The empirical literature on self- medication has so far focused entirely on identifying cases of self-medication in which particular behaviors are linked to therapeutic outcomes. In this study, we frame self-medication in the broader realm of adaptive plasticity, which provides several testable predictions for verifying self-medication and advancing its conceptual significance. First, self-medication behavior should improve the fitness of animals infected by parasites or pathogens. Second, self-medication behavior in the absence of infection should decrease fitness. Third, infection should induce self-medication behavior. The few rigorous studies of self-medication in non-human animals have not used this theoretical framework and thus have not tested fitness costs of self-medication in the absence of disease or parasitism. Here we use manipulative experiments to test these predictions with the foraging behavior of woolly bear caterpillars (Grammia incorrupta; Lepidoptera: Arctiidae) in response to their lethal endoparasites (tachinid flies). Our experiments show that the ingestion of plant toxins called pyrrolizidine alkaloids improves the survival of parasitized caterpillars by conferring resistance against tachinid flies. Consistent with theoretical prediction, excessive ingestion of these toxins reduces the survival of unparasitized caterpillars. Parasitized caterpillars are more likely than unparasitized caterpillars to specifically ingest large amounts of pyrrolizidine alkaloids.

Published by The Company of Biologists Ltd | The Journal of Experimental Biology (2014) 217, 2250-2260 doi:10.1242/jeb.093716 RESEARCH ARTICLE Reduced consumption of protein-rich foods follows immune challenge in a polyphagous caterpillar Peri A. Mason1,*,‡, Angela M. Smilanich2,* and Michael S. Singer3 ABSTRACT In insects, the strongest parallel to adaptive immunity in Advances in ecological immunity have illustrated that, like vertebrates (i.e. immunological memory) is immunological priming, vertebrates, insects exhibit adaptive immunity, including induced whereby exposure to a pathogen acts in an inoculative manner with changes in feeding behavior that aid the immune system. In regard to future exposures in either the treated individual or their particular, recent studies have pointed to the importance of protein offspring (Kurtz and Franz, 2003; Moret and Schmid-Hempel, 2001; intake in mounting an immune response. In this study, we tested the Moret and Siva-Jothy, 2003; Tidbury et al., 2011). However, hypothesis that the polyphagous caterpillar Grammia incorrupta (H. induced immunological defense in insects is not limited to Edwards) (Family: Erebidae) would adaptively change its feeding inoculation effects, and may act through pathogen-induced changes behavior in response to immune challenge, predicting that caterpillars in behavior (Adamo, 2004). For example, desert locusts would increase their intake of dietary protein. We further predicted (Schistocerca gregaria) infected by a fungal pathogen were only that this response would enhance the melanization response, a able to produce viable offspring when they were permitted to component of the immune system that acts against parasitoids. We thermoregulate to fever temperatures (Elliot et al., 2002).

Abstract. A thorough description and detailed photographs of all developmental stages of one of the rar- est Palaearctic moths, Menetries’ tiger moth Arctia menetriesii (Eversmann, 1846) (Lepidoptera, Erebidae, Arctiinae), are presented. Eggs were obtained from a female collected in the Bureinsky Nature Reserve, Khabarovsk Krai, Russia. Data relating to specimens from this region significantly supplements previously published data, which was derived exclusively from more westerly parts of the species’ range. Larvae were reared mainly on dandelion (Taraxacum campylodes G.E.Haglund) in laboratory conditions. Some larvae were fed on Aconitum consanguineum Vorosch. leaves and larch (Larix gmelinii (Rupr.) Kuzen.) needles during certain periods of their lives. It is hypothesized that toxic compounds found in these plants resulted in high mortality rates among larvae prior to pupation. Metamorphosis anomalies in the form of larva-pupa intermediates and various morphological defects of pupae are documented for A. menetriesii for the first time. The assumptions of some researchers about the important role of Larix and Aconitum in larval devel- opment are questioned.

Tritrophic Effects of Host Plants on an Herbivore-Pathogen Interaction Abstract Tritrophic interactions may include directly harmful effects of host plants on herbivores, and directly or indirectly harmful effects of host plants on the natural enemies of herbivores. Tritrophic interactions involving parasitoids and predators have received considerable attention but less is known about how host plants affect entomopathogens. We compared growth and resistance to entomopathogenic nematodes for “woolly bear” caterpillars, Grammia incorrupta(=geneura) (Hy. Edwards) (Lepidoptera: Arctiidae) fed lettuce, Lactuca sativa L. (Asteraceae), versus threadleaf groundsel, Senecio longilobus Benth. (Asteraceae). Both plants are members of the Asteraceae, but only S. longilobus contains pyrrolizidine alkaloids. Caterpillars gained more mass when fed L.
