Application Of Nuclear Magnetic Resonance Based Metabolomics To Study The Central Metabolism Of Staphylococci, Bo Zhang 2014 University of Nebraska - Lincoln

Application Of Nuclear Magnetic Resonance Based Metabolomics To Study The Central Metabolism Of Staphylococci, Bo Zhang

Student Research Projects, Dissertations, and Theses - Chemistry Department

Metabolomics studies the collection of small molecules (metabolites) involved in enzymatically catalyzed reactions, cell signaling and cellular structure. Perturbations in metabolite concentrations have been used to reflect the activity of corresponding enzymes or proteins. Nuclear magnetic resonance (NMR) spectroscopy is a well-known approach for the structure determination of biological macromolecules. Alternatively, NMR has recently been established as a valuable tool of metabolomics, in which NMR spectral signals correlate small molecules with cellular activities. This has been accomplished through the chemometric analysis of high-throughput one dimensional 1H spectra (metabolic fingerprinting) and quantitative metabolite identification based on two dimensional 1H ...


Characterizing The Response Of Multidrug-Resistant Klebsiella Pneumoniae Species To The Application Of A Phage Cocktail, Steven Liu 2014 California Polytechnic State University

Characterizing The Response Of Multidrug-Resistant Klebsiella Pneumoniae Species To The Application Of A Phage Cocktail, Steven Liu

Symposium

Project Summary: The application of bacteriophages to treat bacterial infections is known as phage therapy, which takes advantage of bacteriophage’s natural ability to infect and lyse bacterial hosts. Phages have been shaped by billions of years of evolution to be highly specialized deliverers of bactericidal agents to the cytoplasm of their target bacteria. Ever since discovery of bacteriophages in 1915, phage therapy was recognized as a potentially powerful tool for eliminating bacterial infections. The effectiveness of phage therapy can be increased by creating a mixture of multiple phages to target a wider variety of bacterial strains. Furthermore, phage therapy ...

Low-Cost Strider For Guatemala, Nicole Catherine Cooper, Gonzalo Hernandez, Jared W. Tower 2014 California Polytechnic State University

Low-Cost Strider For Guatemala, Nicole Catherine Cooper, Gonzalo Hernandez, Jared W. Tower

Mechanical Engineering

The purpose of this project was to create a strider, a type of standing rehabilitation device, for children in developing countries who have trouble walking and supporting their full body weight. The project was initially brought to us by Cal Poly professor Brian Self, who had visited a clinic in San Marcos and determined that there were children there who had difficulties with walking and were a need for a rehabilitation device. The team discussed the problem with Dr. Self, Matt Robinson (a local San Luis Obispo prosthetist), and Cal Poly physics professor Pete Schwartz, all of whom had visited ...

A Systematic Column Performance Comparison For The Confirmation Of Opioids Used In Pain Management By Lc-Ms, Derek Stallard 2014 East Tennessee State University

A Systematic Column Performance Comparison For The Confirmation Of Opioids Used In Pain Management By Lc-Ms, Derek Stallard

Undergraduate Honors Theses

In this study, three different chromatographic column chemistries (C18, Pentafluorophenyl (PFP), Hydrophilic Interaction Chromatography (HILIC)) were compared under optimal conditions to determine which stationary performed best in the separation and detection of a mixture of opioids using LC-MS. Furthermore, these stationary phases were examined in three different column technologies – traditional silica, porous shell, and porous polymer (PRP). The PRP column had the best peak shape for all 13 opioids and dominated for later-eluting compounds. In terms of column reproducibility, the Hamilton C18 column had the lowest %RSD values. The Kinetex HILIC produced the most theoretical plates and best resolution for ...


Molecular Chaperone Tools For Use Against Neurodegenerative Diseases, Matthew Tinkham 2014 University of Rhode Island

Molecular Chaperone Tools For Use Against Neurodegenerative Diseases, Matthew Tinkham

Senior Honors Projects

A noted characteristic found in several neurodegenerative disorders, including Alzheimer’s Disease, Parkinson’s Disease, Huntington’s Disease and bovine spongiform encephalopathy, is the accumulation of amyloid plaques in the brain. Amyloid plaques contain deposits of fibrillar aggregates of misfolded proteins that disrupt normal functionality in neurons. Certain variants of these misfolded proteins are self-replicating; these self-replicating amyloids are termed prions (for infectious protein). We are interested in how protein misfolding contributes to amyloid formation and how molecular chaperone proteins can change the formation of amyloid deposits. Chaperone proteins function by catalyzing the proper folding of other proteins, the refolding ...

Bridging Classroom And Lab Teaching In Audiology Using Problem Based Learning, Sriram Boothalingam 2014 Western University

Bridging Classroom And Lab Teaching In Audiology Using Problem Based Learning, Sriram Boothalingam

Teaching Innovation Projects

In traditional classroom settings, disciplinary content is generally presented first and students’ abilities to acquire this knowledge are then assessed through assignments and exams. Problem based learning (PBL), on the other hand, works in reverse: students learn in the context of the problem to be solved (Ram, 1999). PBL is based on both learning theories and constructivist principles.

In Audiology, students’ learning is divided: they study theory in classrooms and the use of sophisticated equipment, and instruments, in lab practicum, separately. In clinical placements, however, student audiologists encounter diverse patients and, consequently, are expected to draw from their theoretical knowledge ...


Determining Knee Loading For Abnormal Gait, Joel D. Hutchison, Dana C. Madsen, Timothy L. Norman, J. D. Blaha MD 2014 Cedarville University

Determining Knee Loading For Abnormal Gait, Joel D. Hutchison, Dana C. Madsen, Timothy L. Norman, J. D. Blaha Md

The Research and Scholarship Symposium

The purpose of this study was to take known experimental loads throughout normal gait and to find the corresponding loading at the knee for both normal gait and abnormal gait. Abnormal gait was defined as a person with varus, i.e. “bowleggedness”, or a person who had an external rotation of the femur (or the inability to internally rotate the femur) which caused an indirect varus in the forward positions of gait. This problem was approached by imposing static equilibrium on the femur. This allowed the loads at the knee to be calculated from the loading at the hip. In ...

Blood Pressure Monitoring Of Hypertensive Patients In Primary Care: Barriers And Facilitators To Ambulatory, Office, And Home Blood Pressure Monitoring In The Context Of The Triple Aim, Elizabeth Andrews 2014 University of Southern Maine

Blood Pressure Monitoring Of Hypertensive Patients In Primary Care: Barriers And Facilitators To Ambulatory, Office, And Home Blood Pressure Monitoring In The Context Of The Triple Aim, Elizabeth Andrews

Muskie School Capstones

Hypertension represents a population health issue in that many patients are misdiagnosed and over-or-under medicated. Research has indicated that overestimating the true blood pressure by 5 mmHg leads to over 30 million Americans being inappropriately treated with blood pressure medication (Handler, 2009). Blood pressure measurements taken in the office are often inaccurate due to patient behaviors, improper technique, and observer errors, yet providers are still using this method to diagnose hypertension. Therefore, considering other methods of blood pressure for the diagnosis and management of hypertension is important to the healthcare quality for millions of Americans.

The main objective of this ...


Defining Obesity: An Argument For The Social Environment Perspective, Meghan McInnis 2014 Providence College

Defining Obesity: An Argument For The Social Environment Perspective, Meghan Mcinnis

Annual Undergraduate Conference on Health and Society

It is well documented that obesity is a growing problem in the U.S. and worldwide. By 2010, 35.9% of U.S. adults age 20 and older were obese (Overweight and Obesity, CDC). Obesity has been associated with many health problems, including hypertension, type 2 diabetes, osteoarthritis, stroke, and cardiac disease (Lucey, 2008, p.202). What has just been described is the traditional, medicalized narrative of obesity. In this narrative, obesity is viewed as an epidemic that demands an immediate and widespread response (Lucey, 2008, p.202). The blame is placed largely on individuals, while social factors, such as ...

Refining Best Practices For The Diagnosis Of Autism: A Comparison Between Individual Healthcare Practitioner Diagnosis And Transdisciplinary Assessment., Jessica Rae Stewart, Debra C. Vigil, Erika Ryst, Wei Yang 2014 University of Nevada, Las Vegas

Refining Best Practices For The Diagnosis Of Autism: A Comparison Between Individual Healthcare Practitioner Diagnosis And Transdisciplinary Assessment., Jessica Rae Stewart, Debra C. Vigil, Erika Ryst, Wei Yang

Nevada Journal of Public Health

The purpose of this study is to compare the diagnostic decision-making of individual healthcare practitioners against that of a transdisciplinary team. Despite national recognition of transdisciplinary assessment as the gold standard diagnostic approach, autism is most frequently diagnosed by individuals working independently in a variety of disciplines. The current study examined how closely these individual practitioners make diagnoses matching that of a transdisciplinary team. Twenty professionals from five different disciplines viewed videotape clips of fifteen children previously assessed by a transdisciplinary team. Results confirmed that individual healthcare practitioners matched the transdisciplinary team diagnosis on average only 65.6% of the ...


Ultra High Field (7t) Magnetic Resonance Imaging Of Intracranial Vessel Wall, Pablo Lopez-Ojeda 2014 Western University

Ultra High Field (7t) Magnetic Resonance Imaging Of Intracranial Vessel Wall, Pablo Lopez-Ojeda

University of Western Ontario - Electronic Thesis and Dissertation Repository

Intracranial vessel wall imaging may be accomplished with high-field (7T) magnetic resonance (MRI). To determine its feasibility, a 7T MR protocol was defined using Polyvinyl-alcohol cryogel (PVA-C) phantom vessels and healthy subjects.

A 2D matrix construct of PVA-C vessel phantoms of different diameters and wall thicknesses was scanned. Three observers measured the phantom images, one of which three times. Physical measurements were performed using a digital caliper. Ten volunteers were scanned using three different MRI sequences (TSE-3D, FLAIR, MPRAGE). Imaging assessment was performed in different circle of Willis (COW) segments. Reliability and accuracy of the measurements was analyzed by inter ...


L-Carnitine Supplementation: A Potential Treatment For Cancer Cachexia, Aaron Kwong, Obaidullah Khan, Katrina Fleming, Sina Moshiri, Muhammad Hashmi 2014 McMaster University

L-Carnitine Supplementation: A Potential Treatment For Cancer Cachexia, Aaron Kwong, Obaidullah Khan, Katrina Fleming, Sina Moshiri, Muhammad Hashmi

The Meducator

Cachexia is a paraneoplastic syndrome that exhibits rampant muscle wasting, unintentional weight loss, fatigue, weakness, and overall loss of appetite, none of which can be abated by an increase in caloric intake. Metabolic derailment by cachexia is so severe in cancer patients that it can shorten lifetime expectancy and lead to death before the course of treatment is finished. Etiology may involve proinflammatory cytokines, but the abnormal loss of muscle, protein, and fat suggests an underlying metabolic dysfunction that contributes to cachexia. Previous research has shown reduction of L-carnitine in cachectic patients and chemotherapy-induced damage to the L-carnitine transport system ...

Optimal Screening Approaches - Coordinating Optimal Screening Programs In Canada: A Multifacted Approach, Eric Chen, Hamza Qamar

The Meducator

Disease screening is the process of testing asymptomatic individuals for the risk or presence of disease. However, the advent of advanced screening technologies in recent decades poses a challenge to the Canadian health system. The lack of a consistent screening policy among Canadian provinces and poor adherence to screening guidelines have compounded the challenge. The McMaster Health Forum convened a stakeholder dialogue on October 17, 2013 with regards to supporting optimal screening practices in Canada. In consultation with stakeholders, the Forum created an issue brief describing the problem, three elements of a comprehensive approach to address this problem, and key ...


Obtaining A Diagnosis Of Fetal Alcohol Spectrum Disorder: Experiences Of Caregivers And Professionals, Erica R. Lundberg 2014 Western University

Obtaining A Diagnosis Of Fetal Alcohol Spectrum Disorder: Experiences Of Caregivers And Professionals, Erica R. Lundberg

University of Western Ontario - Electronic Thesis and Dissertation Repository

The current study describes the lived experiences of stakeholders in a community-based fetal alcohol spectrum disorders assessment clinic. A qualitative methodology was used. Five participants, one caregiver and four professionals, were interviewed about their experiences. Six themes emerged from this process including: clinic organization: systemic strengths and challenges; attitudes and approach: laying the foundation; beyond yes or no: assessment and diagnosis; the moment of truth: delivering the diagnosis; outcomes: what happens after the diagnosis?; what does the future hold? next steps and needs. These themes formed a sequential story-telling of participant experience. Study results are critiqued and practical implications are ...
