Feasibility And Effects Of Accelerometer Based Feedback On Paretic Upper Extremity Amount Of Use In The Home Setting In Subjects Chronic Post-Stroke, Nathan Pohl, Amber Kuehn, Mishgan Abdullah Jan 2015

Feasibility And Effects Of Accelerometer Based Feedback On Paretic Upper Extremity Amount Of Use In The Home Setting In Subjects Chronic Post-Stroke, Nathan Pohl, Amber Kuehn, Mishgan Abdullah

Undergraduate Research Posters 2015

Purpose : to (1) evaluate the feasibility of using accelerometers in the home to quantify how much subjects chronic post-stroke (PS) use their upper extremities (UE), (2) measure differences between amount of UE movement in subjects PS and a healthy control group (HC), (3) determine the effects of accelerometer based feedback on paretic UE use in subjects PS, and (4) determine if those effects are retained over time. Methods : Six subjects PS wore accelerometers for 3 weeks with two feedback sessions given during week two. Seven HC subjects wore accelerometers for one week. Accelerometer based outcome measures included relative …


Safe Movement Practices By Stnas For Residents In Nursing Homes, Christine Fortuna Jan 2015

Safe Movement Practices By Stnas For Residents In Nursing Homes, Christine Fortuna

Undergraduate Research Posters 2015

Previous research reports that with compliance, safe movement programs and policies play a large roll in reducing worker injury and safe patient handling. The purpose for our research is to better understand the daily safe movement practices of State Tested Nursing Assistants as it relates to the safe handling and transferring of patients. We used Qualtric software to electronically survey 14 STNAs from Jenning’s Center for Older Adults Upper Level Neighborhood. The survey consisted of 7 forced choice questions and 19 open ended or follow up questions. The scope of our research covers the complexities of the daily tasks of …


Dynamics Of An Optically Trapped Particle, Flaherty Justin Jan 2015

Dynamics Of An Optically Trapped Particle, Flaherty Justin

Undergraduate Research Posters 2015

Particles trapped in a laser experience a linear restoring force that keeps them centered in the trap and will undergo restricted Brownian motion. The Brownian motion causes a change in the scattered laser light. The scattered light is projected onto a Quadrant Photodiode and can be used to obtain the Mean Squared Displacement of the particle, as well as the linear spring constant of the laser trap. The spring constant can be used to obtain the force applied by the laser trap, which is in the realm of piconewtons.


Development Of A Gc-Ms Method For Investigation Mouse Plasma Amino Acid Levels And Their Significance To The Circadian Clock, Kylin Emhoff Jan 2015

Development Of A Gc-Ms Method For Investigation Mouse Plasma Amino Acid Levels And Their Significance To The Circadian Clock, Kylin Emhoff

Undergraduate Research Posters 2015

An extraction procedure and gas chromatography mass spectrometry (GC-MS) method was developed for quantitation of plasma amino acids. The experimental workflow included extraction of amino acids from plasma, followed by derivatization protocol for GC-MS compatibility. Automated Mass spectral Deconvolution and Identification System (AMDIS) and laboratory developed library was used for compound identification. Levels of plasma amino acids were calculated based on one point calibration with non-physiological amino acid L-norvaline as internal standard. The assay was applied to obtain and monitor levels of plasma amino acids to study the effect of feeding restriction on the circadian clock in mice. The circadian …


Synthesis Of Optimal Polymeric Microgels And Their Characterization With Light Scattering, Christan Gunder, Daria Kulyk Jan 2015

Synthesis Of Optimal Polymeric Microgels And Their Characterization With Light Scattering, Christan Gunder, Daria Kulyk

Undergraduate Research Posters 2015

Polymeric microgels were synthesized in by chemically crosslinking hydroxypropylcellulose (HPC) chains with each other in aqueous solutions of sodium hydroxide at temperatures above the low solution critical temperature (LCST) of HPC. In order to create a narrower size distribution of HPC microgels, surfactant (dodecyltrimethylammonium bromide, DTAB) was added. It was found that, LCST of the solution moved from ~40C up to 80C with an increase in DTAB concentration from 0 to 12 g/l. Formed microgels were be characterized by dynamic light scattering (DLS). Microgel solutions synthesized so far resulted in reasonably monodispersed nanoparticles between the sizes of 150-90 nm below …


Nitrosylation Of S100a8/ A9 Protein Complex By Inducible Nitric Oxide Synthase, Kia Smith Jan 2015

Nitrosylation Of S100a8/ A9 Protein Complex By Inducible Nitric Oxide Synthase, Kia Smith

How does the body fight infection? What causes inflammation? These are only a few questions that have been asked by many doctors across the globe. One thing that is known for certain about infection is that there is a particular sub-group of enzymes called NOS’s (eNOS, nNOS and iNOS) that produce Nitric Oxide (NO), a molecule radical capable of oxidizing proteins and alter their function. In our study we focus on inducible Nitric Oxide Synthase (iNOS). NOS’s are comprised of oxidase and reductase domains liked by Camodulin (CAM), a polypeptide linker. According to prior studies and SEM photographs, inducible Nitric …


Enhancement Of Solar Energy Conversion In Bio-Derived Cells Via Side Selective Modification Of Photosystem I, Uchechukwu Obiako, Evan Gizzie Jan 2015

Enhancement Of Solar Energy Conversion In Bio-Derived Cells Via Side Selective Modification Of Photosystem I, Uchechukwu Obiako, Evan Gizzie

Undergraduate Research Posters 2015

Deleterious effects of some methods used to harness energy from the environment today have garnered the exploration of safer and more reliable options, specifically solar energy conversion. Current solar cell technology has yielded quantum efficiencies commonly in the range of 10-20% but is limited by extensive processing methods, high cost, and need for rare materials. However, bio-derived solar cells containing Photosystem I (PSI) address these problems as PSI is highly abundant, very efficient, and low-cost. PSI acts as a biomolecular photodiode through rapid photoexcited charge separation, making it very promising for use as an integral element in solar cells. To …

Chromosome miss-segregation during meiosis is a major factor contributing to birth defects as well as many genetic anomalies through the formation of aneuploid gametes, i.e. gametes with a deficit or surplus of one or several chromosomes. The synaptonemal complex (SC) is a major protein structure assembled with the synapsis of homologous chromosomes and is conserved from unicellular yeast to humans. One of its major roles during prophase I in meiosis is providing a structural framework for the maintenance of synapsis to facilitate the completion of reciprocal crossover events. Failure to form an effective SC or to experience crossover events leads …
