Distribution Of Sphaeriid Clams In Lake Erie Twenty-Five Years After Invasion Of Dreissena, Michael Keller
Undergraduate Research Posters 2015
Clams in the family Sphaeriidae are widespread native mollusk species that are often overlooked. The distribution of these organisms in Lake Erie has not been examined in the 25 years since the initial invasion of the zebra mussel, Dreissena polymorpha. Carr and Hiltunen identified 10 species of Sphaeriidae in Western Lake Erie in 1961, of which Pisidium casertanum, P. compressum, P. nitidum, Sphaerium corneum, and S. striatinum and Musculium transversum, contributed 89.7% of all fingernail and pea clams sampled and were considered common. Four other species were reported as rare. Our research examines whether the distribution of Sphaeriid clams in …

For all microorganisms, acquisition of metal ions is essential for survival in the environment or their infected host. Metal ions are required in many biological processes as cofactors for proteins or structural elements for enzymes. These ions play a role in chemotaxis, phosphorylation, transport of sugars and proteins, and initiation of DNA replication, among other things. It is critical for bacteria to ensure that metal uptake and availability meet its physiological needs; too little can impede these important biological processes, while too much can be toxic leading to radical formation which can cause damage to proteins and cell structures (Porcheron, …
Statistical Analysis Of Dasi Questionnaire And Modeling The Prediction Of Heart Failure Risk In Patients, Christian Negron
Statistical Analysis Of Dasi Questionnaire And Modeling The Prediction Of Heart Failure Risk In Patients, Christian Negron
Undergraduate Research Posters 2015
9,880 patients were asked to complete the DASI questionnaire along with other questions to assess the predictability of heart failure risk. In this paper we attempt to reduce the amount of questions asked by hierarchical clustering of the question responses to determine if there is a change in the predictability of heart failure risk in patients. The data was modeled using Cox hazards multiple regression and validated through ROC and AUC. Our validation models show there is no difference between the usage of 12 and 6 DASI questions, therefore improving the simplicity of the questionnaire. Abbreviations: DASI, Duke Activity Status …
Optimizing The Design And Potency Of Diterpenic Acid Derivatives To Improve Cell Membrane Permeability And Hsp27 Targeting Characteristics, Aicha Quamine
Undergraduate Research Posters 2015
Heat shock protein 27 (Hsp27) acts as a protective protein allowing it to play an integral role in aiding cancer cell resistance. Stress-induced Hsp 27 overexpression aids in the stabilization of partially denatured proteins to establish protein refolding resulting in thermotolerance, inhibition of apoptosis, cytoprotection, etc. As a result of rapid proliferation and general instability, cancer cells exhibit increased dependency on the support of Hsp 27 and it’s chaperone proteins, therefore generating an ideal target for anticancer therapy. Copalic acid, a clerodane diterpenoid, has already been confirmed in effective chaperone inhibition and antiproliferative synergistic effect. We hypothesize that by optimizing …
Dual Stimuli Response Frequency And Stimulus Choice Of The African Clawed Frog, Xenopus Laevis, When Presented With Two Stimuli, Mingo Rolince, Heidi Pignolet, Alexa Hoy
Dual Stimuli Response Frequency And Stimulus Choice Of The African Clawed Frog, Xenopus Laevis, When Presented With Two Stimuli, Mingo Rolince, Heidi Pignolet, Alexa Hoy
Undergraduate Research Posters 2015
This preliminary study examines responses of African Clawed Frogs to simultaneous presentation of two stimuli. Frogs were tested in a round arena with water 4 cm deep. Four stimulus rods driven via computer-controlled stepper motors were concealed in a screen suspended above the water. These rods could present a lateral line stimulus, a visual stimulus, or a combination of both. Overall, reactions and no reactions were evenly distributed--51.1% and 48.9%, respectively. Frogs responded more frequently to rostral than caudal stimuli (chi-squared 20.8, df=11, p < 0.04). Frogs reacted more to stimuli between -90° and 90°. Turn angle depended linearly on stimulus angle (e.g., Turn angle = 0.44 + 0.64 x Stimulus angle; pslope < 0.0001; R2adj = 69.5%). (The distributions of stimulus angles appear slightly skewed as often the same stimulus rod was retested after the frog responded and partially oriented towards it, prompting a second test with smaller angles.) Two stimuli did not elicit more responses than one stimuli (P=0.25). The frogs’ choice of stimulus depended primarily on stimulus proximity and angle, not stimulus type. When presented with two stimuli, the frog chose the nearer stimulus and the more rostral stimulus (p < 0.0001). The largest factor in predicting the frog’s choice of stimuli seems to be the linear distance from the stimuli to the frog.

Undergraduate Research Posters 2015
In order to obtain a tangible basis for vaccine targets, it is crucial to understand the role of proteins at the site of invasion. In previous study, 27 novel rhoptry proteins were identified by MudPIT analysis and immunoelectron microscopy. In this investigation, the conservation of rhoptry genes between Plasmodium yoelii and Plasmodium falciparum was assessed. From the previously identified rhoptry genes, 14 were investigated with the orthologues/paralogues of the Plasmodium falciparum, Plasmodium yoelii, Plasmodium chabaudi, and Plasmodium berghei. Also, primers designed for the 14 Plasmodium yoelli rhoptry genes were used to test DNA amplification with the PCR. Amplification of Plasmodium …
Cultural Differences In Coping And Depression Between Individuals Of Middle-Eastern And Non-Arab Backgrounds, Khadeja Najjar
Cultural Differences In Coping And Depression Between Individuals Of Middle-Eastern And Non-Arab Backgrounds, Khadeja Najjar
Undergraduate Research Posters 2015
The Middle Eastern (Arab) demographic is a growing, yet neglected cultural group in mental health research. While Arabs are more predisposed to depression than other ethnic groups in US, little is known about mechanisms that account for this risk. One set of mechanisms may be the use of ineffective (maladaptive) coping or insufficient use of effective (adaptive) coping responses, which are robust predictors of depression in US samples, but virtually unexamined in Arabs. Further, the effect of a coping is influenced by culture, which, for Arabs, may change as a function of acculturation. Thus, the present study aimed to examine …

Deducing Shape Of Anisotropic Particles In Solution From Light Scattering: Spindles And Nanorods, Ilona Tsuper, Dan Terrano
Undergraduate Research Posters 2015
Depolarized Dynamic light scattering (DDLS) enables to measure in situ rotational and translational diffusion of nanoparticles suspended in solution. Their size, shape, diffusion, and intermolecular interactions can be interred then from DDLS data using various models of diffusion. Incorporating DDLS to analyze the dimensions of easily imaged elongated particles, such as Iron (III) oxyhydroxide Spindles (FeOOH) and gold coated Nanorods, will allow a deeper understanding between rotational/translational diffusion and size distribution of hard-to-image anisotropic wet systems such as micelles, microgels, and protein complexes. The emphasis of this study was to look at the aged FeOOH Spindle sample, and explore the …

Prosthetic Socket Surface Initialization – For Future Use In Subject-Specific Socket Optimization, Brahm Powell
Undergraduate Research Posters 2015
For persons with lower limb amputations the human-prosthesis interface, termed the “prosthetic socket,” remains an area of ongoing research. Patient satisfaction is closely tied to the physical comfort of the device, which includes performance factors such as fit, moisture management, stiffness/rigidity, stress concentrations, range of motion, etc. An imbalance in these factors may result lack of mobility for the patient or worse, pressure sores, a precursor to debilitating deep tissue ulcerations. Ulcerations are well documented and current socket fitting techniques, as performed by a “prosthetist,” are largely subjective, relying on the prosthetist's experience and feedback from the patient. With the …

Case Transition Format And Lexical Decision Performance: Does Spacing Reduce The Benefit Of Orthographic Regularity?, Kristyn Oravec, Maryam Assar, Hannah Princic
Undergraduate Research Posters 2015
Some models of visual word identification propose that identification is analytic— mediated exclusively by letter identification. However, some studies have shown that there are phenomena that suggest a route to word identification involves holistic stimulus properties. In previous research, using a lexical decision task, in which participants are asked to determine whether letter strings are words or nonwords, we have found that response times to orthographically regular words (i.e., lowercase, uppercase, and initial uppercase formats) are faster than those to orthographically irregular words (i.e., words that include a case transition other than initial uppercase to lowercase). In this experiment, we …

Balance Training Application Of A Systematic Framework For Clinical Decision Making In Therapeutic Gaming For Older Adults, Brian Boccieri
Undergraduate Research Posters 2015
Falling is a major health concern for older adults. Balance is crucial in order to prevent falls. For balance to be functional an individual must be able to maintain balance while focusing on other tasks. For example, an individual must focus on more than just staying upright during walking while drinking a mug of coffee, or during standing while washing dishes. There are a countless number of daily activities that challenge balance. One of the problems with current clinical balance rehabilitation is that the training is often completed using isolated exercises that do not include the various other cognitive and …

Assaying The Splicing Activity Of Novel Human Disease Variants Of U4atac Snrna, Maitri K. Patel, Rosemary C. Dietrich
Undergraduate Research Posters 2015
In eukaryotes, pre-messenger RNA (pre-mRNA) splicing is an essential process in gene expression. Splicing is carried out by a dynamic multi-megadalton RNA-protein complex known as the spliceosome. Sequential transesterification reactions catalyzed by the spliceosome convert pre-mRNA to mRNA by removing the intervening sequences (introns) and joining the coding sequences (exons) together. Small nuclear RNAs (snRNAs) are essential splicing factors. Biallelic mutations of the human RNU4ATAC gene, which codes for U4atac snRNA, have been identified in patients diagnosed with Microcephalic Osteodysplastic Primordial Dwarfism type I (MOPD I). MOPD I is an autosomal recessive disorder characterized by extreme intrauterine growth retardation, multiple …

Regulation Of Sister Chromatid Cohesion By Eco-1 And Wapl-1 During Meiosis And Mitosis, Kyle T. Schroeder
Undergraduate Research Posters 2015
Cohesin is a widely conserved, tetrameric protein complex that tethers replicated sister chromatids during meiosis and mitosis. Two cohesin subunits, SMC-1 and SMC-3, and a third subunit, the α-kleisin, form a ring proposed to encircle sister chromatids. Different kleisins associate with cohesin during mitosis and meiosis. SCC-1 is the mitotic kleisin. Meiotic cohesin can associate with either REC-8 or COH-3/4. REC-8 and COH-3/4 cohesins differ greatly in their functional properties, indicating that the kleisin determines meiotic cohesin function. Early in meiosis, REC-8 and COH-3/4 cohesins are triggered to become cohesive at different times and by different mechanisms. Later in meiosis, …

Cell Surface Sialylation Status Of Monocytes And Macrophages, Henry Wang, Dan Wang
Undergraduate Research Posters 2015
Sialic acids (SAs), a family of 9-carbon containing acidic monosaccharides, often terminate the glycan structures of cell surface glycoconjugates such as glycoproteins and glycolipids. The levels and linkages of sialic acids named as sialylation status vary as cell environment changes related to both physiological and pathological processes. Changes in sialylation of cell surface modulate cellular activity. SAs are highly involved in the immune system, however, the sialylation status related to individual immune cells and their activation state and functions are still unknown. In this study, we used a newly developed LC-MS/MS method to examine the cellular SA content during THP-1 …

Undergraduate Research Posters 2015
Most investigators of word identification agree that information is processed through a hierarchical system in which units at progressively higher levels respond to features, letters, letter combinations (e.g., pairs, or bigrams), and possibly words. Grainger et al. (2014) found support for the role of adjacent-letter bigrams in an experiment in which participants saw target strings flanked by bigrams, such as BI BIRD RD and CE BIVS NT, and judged whether the targets were words. They found, for words, that flanking bigrams facilitated performance when the flanking bigrams contained letters from the target, and that the order of bigrams relative to …

Novel Regulation Of The Pro-Apoptotic Protein Puma In Response To Hypoxia, Mareem Ali, Brianna Boslett
Undergraduate Research Posters 2015
Ischemic injury in skeletal muscle caused by hypoxic (low oxygen) conditions occurs in response to vascular and musculoskeletal traumas, diseases and following reconstructive surgeries. Hypoxia induces apoptotic cell death. We have reported that the protein PUMA plays a critical role in the apoptosis of myoblasts in response to culture in differentiation media as well as exposure to DNA damaging chemotherapeutic agents. We have also determined that the transcription factor MyoD, known to control the differentiation process, also plays a role in these apoptotic processes by directly increasing the expression of PUMA mRNA. Herein, we report an increase in PUMA protein …

Undergraduate Research Posters 2015
The production of gametes in Saccharomyces cerevisiae via meiosis is under strict regulatory control where proper segregation of homologous chromosomes into gametes requires physical linkage via crossovers. Cells that initiate meiotic recombination but do not process programmed double strand breaks into crossovers enter meiotic arrest. The main goal of the current project was whether overexpression of gene Y is sufficient to bypass the meiotic arrest in prophase I exhibited by dmc1 deletion and a zip1 mutant that carries an internal deletion. DMC1 is a recombinase that promotes homologous recombination. ZIP1 is a transverse filament protein of the synaptonemal complex (the …

Effect Of Solidification Through Cross-Section Change On Dendritic Array In Single Crystal Castings, Christopher Stacey, Masood Ghods
Undergraduate Research Posters 2015
Dendritic single crystal turbine blades are the most critical component in a gas turbine engine. These are made by directional solidification in ceramic molds having many cross-section changes. Abrupt cross-section changes during casting are the source of casting defects, such as, freckles and spurious grains. Purpose of this study was to examine the role of convection associated with cross-section changes in producing microstructural defects. Al-7%Si alloy was directionally solidified at 11, 29 and 73 μm s-1 in graphite crucibles having abrupt cross-section decrease and cross-section increase to simulate solidification of turbine blades. It is observed that, (i) shrinkage flow leads …

The Effect Of Depression Symptoms On The Cardiac Autonomic Response To Positive Mood Induction, Elizabeth Golias, Khadeja Najjar, Brock Bodenbender
Undergraduate Research Posters 2015
Depression is characterized by a reduced capacity to experience pleasure (hedonic capacity). A growing literature suggests that hedonic capacity is supported by the sympathetic (SNS) and parasympathetic (PNS) branches of the autonomic nervous system. Both branches may work in a reciprocal fashion, or in tandem, reflecting co-activation of the SNS and PNS. While reduced PNS and increased SNS activity are associated with happy states among healthy individuals, preliminary findings suggest that depressed persons evidence blunted physiologic responses across a variety of emotion inducing stimuli. Much of this work, however, has examined PNS and SNS activity separately, and never with respect …

Transmembrane and coiled-coil domains 1 (TMCO1) is highly conserved in amino acid sequence among species and ubiquitously expressed in all human tissues. Homozygous frameshift mutation in TMCO1 causes distinctive craniofacial dysmorphism, skeletal anomalies, and mental retardation. However, its physiological functions, particularly in cancer biology, are largely unknown. In this study, we have found that knock down of TMCO1 in HeLa cells, a human cervical cancer cell line, and U2OS cells, an osteosarcoma cell line, remarkably inhibited their migratory capability; TMCO1 was highly expressed in the cells of the invasive front of high grade lung cancer and metastatic cancer cells in …

Learning To Drive A Simulator: Impact Of Prolonged Practice, Eyal Greenhouse, Samah Soki
Undergraduate Research Posters 2015
Most driving simulation experiments begin with a practice scenario, to allow participants to learn how to interact with the driving simulator. During practice, driving performance improves such that consistent steering and speed control is exhibited. It is unclear however, whether driver performance will degrade with prolonged practice, and whether the fidelity of the simulator contributes to this degradation. Therefore, a driving simulation experiment was conducted to examine the performance of drivers over one hour of driving, using two different simulators: DriveSafety RS-100 and RS- 600 models. The RS-100 is made up of a Logitech steering wheel and pedals attached to …
