Kinetics Of Running On Arboreal Versus Terrestrial Substrates In Siberian Chipmunks, Eliza J. Dorsey
Kinetics Of Running On Arboreal Versus Terrestrial Substrates In Siberian Chipmunks, Eliza J. Dorsey
Undergraduate Research Posters 2012
Many mammals travel on both tree branches and flat ground in their natural habitat. Forelimbs were found to have the dominant role in braking on both substrates, while hindlimbs had the dominant role in propulsion on both substrates. However, the forelimb aided in propulsion more so than the hindlimbs contributed to braking on both substrates.
Functional Morphology Of Rat Hands And Feet: Correlation With The Ability To Grip Tree Branches During Locomotion, Jessica Elaine Fonce
Functional Morphology Of Rat Hands And Feet: Correlation With The Ability To Grip Tree Branches During Locomotion, Jessica Elaine Fonce
Undergraduate Research Posters 2012
Anatomy and function are usually closely related. Since locomotion on tree branches is common among mammals, we expect to find that the anatomy is well adapted for gripping narrow cylindrical branch-like substrates. Based on the anatomy alone, rats are built for locomotion across cylindrical branches as well as terrestrial substrates.

Normalizing For Noise Removal From Electrocardiogram Signals, Dominique Diamond Brooks, Daniel J. Simon

Electrocardiography (ECG) measures the electrical impulse of the heart over time using electrodes that attached to the body. Designing a computational program using a synthetic ECG to test Normalized Least Mean Square (NLMS) filter serves as a basis to remove noise from the signal.
Comparison Of Responses In Proactive Vs. Reactive Balance Control, Christina A. Sadowski, Deborah Espy
Comparison Of Responses In Proactive Vs. Reactive Balance Control, Christina A. Sadowski, Deborah Espy
Undergraduate Research Posters 2012
Even though recent research suggests reactive balance training (unexpected, external perturbations) has more effective, long term results than proactive training (self-initiated actions), the latter is used most often in a clinical setting due to its affordability and convenience. This pilot study sought to develop a safe, affordable, and easily portable perturbation-inducing device to be used for reactive balance training.
Role Of Histone Modifications In Meiosis, Mason Allen, Neeraj Joshi
Role Of Histone Modifications In Meiosis, Mason Allen, Neeraj Joshi
Undergraduate Research Posters 2012
Meiosis I is characterized by events taking place between homologous chromosomes called crossing over in which double stand breaks (DSB) are formed and repaired using the homologous chromosome as a template. To see if Gene A shared the same role as Gene B, double mutants were created to test chromosome segregation and DSB repair as compared with Gene B deletions. The spore viability of double mutants and their potential implications will be discussed.

Size And Shape Characterization Of Salt Dependent Thermoreversible Micelles Synthesized From Elastin-Like Polypeptides, Kaitlin W. Vandemark
Undergraduate Research Posters 2012
Environmentally responsive nanoparticles synthesized from Elastin-Like Polypeptides (ELP) present a promising system for applications such as biosensors, drug delivery vehicles, and viscosity modifiers.

Telomeres are DNA-protein complexes located at the ends of linear chromosomes. Acting like a cap, they protect chromosome ends from degradation and rearrangement, maintaining genomic stability. Our lab has identified several T. brucei telomere proteins, including TRF (TTAGGG Repeat-binding Factor), TIN2 (TRF1-interacting Nulcear Protein 2) and RAP1 (Repressor Activator Protein 1) homologs. We are currently verifying the interactions between the new candidates and TbTIN2 or TbRAP1.
Light Scattering Study Of Elongated Particles: From Inorganic Nanorice To Polypeptide Micelles, Philip Dee
Light Scattering Study Of Elongated Particles: From Inorganic Nanorice To Polypeptide Micelles, Philip Dee
Undergraduate Research Posters 2012
Utilizing the powerful experimental technique of Dynamic Light Scattering (DLS) for size characterization of anisotropic particles can be extremely misleading. Unfortunately, this point is often not realized by researchers who strive for particle sizing of nanoparticles in suspensions. We present a consistent analysis of DDLS results on FeOOH nanorice and outline the potential difficulties and challenges of DDLS application for polypeptide micelles.
Status Of The State-Endangered Mussel, Ligumia Nasuta, In The Upper Cuyahoga River, Rachel E. Andrikanich, Stephanie A. Sredniawa
Status Of The State-Endangered Mussel, Ligumia Nasuta, In The Upper Cuyahoga River, Rachel E. Andrikanich, Stephanie A. Sredniawa
Undergraduate Research Posters 2012
The primary objective of our research was to assess population size and range of Ligumia nasuta, the Eastern Pond mussel in the Cuyahoga River watershed. We conclude that the Eastern Pond mussel may be all but gone from the East Branch and West Branch Cuyahoga Rivers, but may persist in better numbers in Portage County. Further studies are required before the sustainability of this species can be fully assessed.
Analysis Of Crossover Interference In Yeast, Hanna Morris
Analysis Of Crossover Interference In Yeast, Hanna Morris
Undergraduate Research Posters 2012
Meiosis is one type of cell division that produces germ cells. In Meiosis I, the DNA in a diploid cell is doubled and homologous chromosomes separate. In Meiosis II, each pair of sister chromatids are separated, resulting in four haploid daughter cells. The nine intervals were analyzed under several conditions and the number, timing, and distribution of crossovers was determined. Results and their compatibility with current models of synaptonemal complex functions will be discussed.

Proper segregation of chromosomes in Meiosis I requires proper function of the Synaptonemal Complex (SC), a zipper-like protein structure that facilitates recombination events and segregation of homologous chromosomes. Candidates which suppress the phenotype show sporulation and fluorescence on media, and have higher spore viabilities compared to our Zip1C1 control.
Structure-Function Of U11 Snrna In The Minor Splicing Pathway, Mark P. Biro, Jagjit Singh
Structure-Function Of U11 Snrna In The Minor Splicing Pathway, Mark P. Biro, Jagjit Singh
Undergraduate Research Posters 2012
In human, the majority of protein coding genes are interrupted by dispensable intervening sequences (introns). These introns are removed by nuclear precursor (pre) mRNA splicing process to produce a mature mRNA needed for productive protein production in the cell. We are studying the splicing of minor class or U12-type introns which are spliced by U11, U12, U4atac, U5 and U6atac snRNAs. U11 snRNA binds to the 5’ end or splice site of the intron by RNA-RNA base-pairing to initiate the splicing process. Our results show the functionality of the genetic mutation suppressor assay in establishing the role of U11 snRNA …
