The Association Between Different Clinical Methods For Evaluating Lower Extremity Muscular Function, 2011 Old Dominion University
The Association Between Different Clinical Methods For Evaluating Lower Extremity Muscular Function, Roger Olen Kollock Jr.
Human Movement Sciences Theses & Dissertations
Insufficient muscular strength at the hip and thigh may increase an athlete's susceptibility to lower extremity injuries. In an attempt to reduce this risk, researchers have proposed lower limb strength testing within preparticipation physical examinations (PPE) and return-to-play (RTP) evaluations. However, because of cost, mobility, and or set-up time, some methods are not feasible in certain settings. Since methodological approaches between methods can vary, having different contraction modes and testing parameters, substitution of one method for another may not be valid. Therefore, the purpose of this study is three-fold: a) to determine the association between isometric and isokinetic contraction ...

Synthetic probe bacterial DNA was immobilized on a microarray glass slide surface, hybridized with the 48 base pair long biotinylated target DNA and subsequently incubated with streptavidin-coated 2.8 μm diameter magnetic particles. The biosensing platform ...
A Field Evaluation Of A Trap For Invasive American Bullfrogs, 2011 Michigan State University
A Field Evaluation Of A Trap For Invasive American Bullfrogs, Nathan P. Snow, Gary W. Witmer
USDA National Wildlife Research Center - Staff Publications
Native to the eastern United States, American bullfrogs (Rana catesbeiana [Lithobates catesbeianus]) have been introduced in many countries throughout the world. There have been relatively few effective and efficient control methods developed to manage bullfrogs. Particularly in the Hawaiian Islands, Pacific coast of North America, and Japan, finding effective methods for controlling invasive bullfrogs is needed with special emphasis on low impacts for sensitive native species. We conducted a field study to examine the efficacy of a newly designed live trap for capturing invasive bullfrogs. We found that our trap was successful at capturing bullfrogs because we captured up to ...

Although birds with beak deformities have been documented throughout the literature, the recent spike in occurrences in certain regions has caused concern in the scientific community. A major concern relates to the role of contaminants and environmental degradation in causing or exacerbating this epizootic. This study used spatial and statistical analyses to examine the problem from a landscape perspective. The objectives of this study were to 1) locate and compile a database of known bird beak occurrences, 2) conduct a preliminary assessment of the environmental correlates of this epizootic in order to identify patterns, and 3) make recommendations that could ...
Collagen Matrices As An Improved Model For In Vitro Study Of Live Cells Using Raman Microspectroscopy, 2011 Technological University Dublin
Collagen Matrices As An Improved Model For In Vitro Study Of Live Cells Using Raman Microspectroscopy, Franck Bonnier, Peter Knief, Aidan Meade, Jennifer Dorney, Kunal Bhattacharya, Fiona Lyng, Hugh Byrne
Due to its high lateral resolution, Raman microspectrsocopy is rapidly becoming an accepted technique for the subcellular imaging of single cells. Although the potential of the technique has frequently been demonstrated, many improvements have still to be realised to enhance the relevancy of the data collected. Although often employed, chemical fixation of cells can cause modifications to the molecular composition and therefore influence the observations made. However, the weak contribution of water to Raman spectra offers the potential to study live cells cultured in vitro using an immersion lens, giving the possibility to record highly specific spectra from cells in ...
Collagen Binding Proteins In Helicobacter Pylori, 2011 Technological University Dublin
Collagen Binding Proteins In Helicobacter Pylori, Carmel Cremin
Helicobacter pylori is a human pathogen and the causative agent of chronic gastritis, peptic ulcer and gastric malignancies. A number of H. pylori virulence factors have been described including, CagA, VacA, neutrophil activating protein, and expression of receptors for binding to extracellular matrix proteins (adhesins). H. pylori interacts with extracellular matrix (ECM) proteins such as collagen IV, laminin, vitronectin and fibronectin, that can be exposed due to loss of integrity of the gastric epithelial cell layer. These interactions may be important in the pathogenesis of the organism. This study examines the interaction of H. pylori with collagen IV in an ...

A central composite design was employed with a hydrothermal processing time of 10 – 30 min and temperature of 60 – 90 ° C. Predicted models were found to be signifi cant for total phenolic content, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity, total fl avonoids, total condensed tannins, texture and colour. The predicted values for each of the responses were in good agreement with experimental values. Processing time had the most signifi cant ...
The Effect Of Untreated And Enzyme-Treated Commercial Dairy Powders On The Growth And Adhesion Of Streptococcus Mutans, 2011 Technological University Dublin
The Effect Of Untreated And Enzyme-Treated Commercial Dairy Powders On The Growth And Adhesion Of Streptococcus Mutans, Rachel Halpin, D.B. Brady, E.D. O’Riordan, M. O’Sullivan
Dental caries is a common bacterial infection, but the progression of this disease can be delayed by preventing initial attachment of cariogenic bacteria such as Streptococcus mutans to tooth surfaces. This study firstly compares the effect of untreated (UT) and enzyme-treated (ET) dairy powders on the adherence of S. mutans to hydroxylapatite (HA), an analogue of tooth enamel. A fluorescence-based method was used to quantify adherence of S. mutans to HA both in the presence (S-HA) and absence (PBS-HA) of saliva. Secondly, binding of proteins present in the test materials to HA was quantified using bicinchonic acid assays and SDS-PAGE ...
Synthesis, Evaluation And Structural Studies Of Antiproliferative Tubulin-Targeting Azetidin-2-Ones, 2011 Technological University Dublin
Synthesis, Evaluation And Structural Studies Of Antiproliferative Tubulin-Targeting Azetidin-2-Ones, Niamh O'Boyle, Lisa M. Greene, Orla Bergin, Jean-Baptiste Fichet, Thomas Mccabe, David G. Lloyd, Daniela M. Zisterer, Mary J. Meegan
A series of azetidin-2-ones substituted at positions 2, 3 and 4 of the azetidinone ring scaffold were synthesised and evaluated for antiproliferative, cytotoxic and tubulin binding activity. In these compounds, the cis double bond of the vascular targeting agent combretastatin A-4 is replaced with the azetidinone ring in order to enhance the antiproliferative effects displayed by combretastatin A-4 and prevent the cis/trans isomerization that is associated with inactivation of combretastatin A-4. The series of azetidinones was synthetically accessible via the Staudinger and Reformatsky reactions. Of a diverse range of heterocyclic derivatives, 3-(2-thienyl) analogue 28 and 3-(3-thienyl) analogue ...

The structure-activity relationships of antiproliferative β-lactams, focusing on modifications at the 4-position of the β-lactam ring, is described. Synthesis of this series of compounds was achieved utilizing the Staudinger and Reformatsky reactions. The antiproliferative activity was assessed in MCF-7 cells, where the 4-(4-ethoxy)phenyl substituted compound 26 displayed the most potent activity with an IC50 value of 0.22 μM. The mechanism of action was demonstrated to be by inhibition of tubulin. Cell exposure to combretastatin A-4 and 26 led to arrest of MCF-7 cells in the G2/M phase of the cell cycle and induction of apoptosis ...

Nano-Enhanced Food Contact Materials And The In Vitro Toxicity To Human Intestinal Cells Of Nano-Zno At Low Dose, Gordon Chambers, Niall Ó Claonadh, Alan Casey, Clement Higginbotham, Sean Lyons, Sanchali Mukherjee
Nano Zinc Oxide (nZnO) has been shown to display antimicrobial effects which have lead to its application in a number of areas such as antimicrobial surface coatings, anti bacterial wound dressings and more recently in polymer composite systems for use in food contact materials. Concerns have been raised due to the incorporation of nanoparticles in food packaging stemming from the possibility of repeated low dose direct exposure, through ingestion, primarily due to degradation and nanoparticle leaching from the polymer composite. To address these concerns, composites consisting of nZnO and polyethylene were formed using twin screw extrusion to mimic commercial methods ...
Modelling The Effect Of Asparaginase In Reducing Acrylamide Formation In Biscuits, 2011 University of Udine
Modelling The Effect Of Asparaginase In Reducing Acrylamide Formation In Biscuits, Monica Anese, Barbara Quarta, Jesus Maria Frias
The influence of asparaginase on acrylamide formation, as well as colour development, in short dough biscuits was studied. In particular, asparaginase concentration, incubation time and temperature were changed according to an experimental design. As acrylamide formation was found to vary significantly between biscuits obtained by using the same ingredients and process, a mixed effect model was used to model variation of acrylamide concentration. By contrast a fixed effect model was used for colour polynomial analysis. Within the range of study, the overall results allowed the best conditions for minimising acrylamide formation to be found. It can be suggested that acrylamide ...
