Evaluation Of A Multiplex Real-Time Pcr Assay To Simultaneously Detect Streptococcus Pneumoniae And Staphylococcus Aureus In Nasal Samples, Polly Hockberger Dec 2016

Evaluation Of A Multiplex Real-Time Pcr Assay To Simultaneously Detect Streptococcus Pneumoniae And Staphylococcus Aureus In Nasal Samples, Polly Hockberger

All NMU Master's Theses

Invasive disease caused by Streptococcus pneumoniae and Staphylococcus aureus is associated with nasal carriage of these bacteria. Use of a pneumococcal conjugate vaccine (PCV) in children altered nasal carriage rates and reduced infections due to S. pneumonia. Similar studies demonstrate that there is an inverse correlation between S. pneumoniae and S. aureus nasal carriage in children, but this inverse correlation has not been extensively investigated adults. The PCV is now approved for use in adults, a group more likely to be colonized with S. aureus. To investigate the impact of PCV vaccination on S. aureus carriage in adults, the …

A Comparison Of Stride Length And Lower Extremity Kinematics During Barefoot And Shod Running In Well Trained Distance Runners, Peter Francis, James Ledingham, Sarah B. Clarke Phd, Dj Collins, Philip Jakeman Aug 2016

A Comparison Of Stride Length And Lower Extremity Kinematics During Barefoot And Shod Running In Well Trained Distance Runners, Peter Francis, James Ledingham, Sarah B. Clarke Phd, Dj Collins, Philip Jakeman

Journal Articles

Stride length, hip, knee and ankle angles were compared during barefoot and shod running on a treadmill at two speeds. Nine well-trained (1500m time: 3min:59.80s ± 14.7 s) male (22 ±3 years; 73 ±9 kg; 1.79 ±0.4 m) middle distance (800 m – 5,000 m) runners performed 2 minutes of running at 3.05 m·s-1 and 4.72 m·s-1 on an treadmill. This approach allowed continuous measurement of lower extremity kinematic data and calculation of stride length. Statistical analysis using a 2X2 factorial ANOVA revealed speed to have a main effect on stride length and hip angle and footwear to …

Upper Body Characteristics Related To Double Pole Performance In Female Cross Country Skiers, Karmen M. Whitham Aug 2016

Upper Body Characteristics Related To Double Pole Performance In Female Cross Country Skiers, Karmen M. Whitham

All NMU Master's Theses

The purpose of the current study was to correlate upper body (UB) lean mass (UBLM), UB maximal strength (UBMS), and average power production during a 3-min ski ergometer (SERG) test to predict the dependent variable, a one-kilometer uphill double pole time trial (DPTT) on snow. We hypothesized UBLM would be most important to performance. All tests were conducted within four weeks of completing the championship phase of a Division I cross country (XC) ski season. Skiers (n=10; all females) performed the mass-start DPTT on snow (i.e., criterion measure), SERG, and UBMS separated by at least a few days recovery. Lastly, …

Reactive Strength Index-Modified In Different Plyometric Tasks, Josh Walker, Sarah B. Clarke, Emma Waller, Aaron Robey-Broome, Randall L. Jensen Jul 2016

Reactive Strength Index-Modified In Different Plyometric Tasks, Josh Walker, Sarah B. Clarke, Emma Waller, Aaron Robey-Broome, Randall L. Jensen

Conference Presentations

The Reactive Strength Index-Modified (RSlmod) is a reliable method of measuring the explosiveness of an athlete during a range of plyometric exercises. The purpose of the current study was to measure the between-limb differences in RSlmod across three different plyometric tasks. Eleven recreationally active participants performed countermovement jumps, stop jumps and single-leg jumps. The study found no significant differences in RSlmod between dominant and non-dominant limbs across all three tasks (p>0.05), but did find RSI,d to be higher in the stop jump than a countermovement jump and single leg stop jump for both dominant and non-dominant limbs. These findings …

12-Day Adventure Run-Hike Training At Altitude Improves Sea Level 5km Performance, Andrew M. Jones Jul 2016

12-Day Adventure Run-Hike Training At Altitude Improves Sea Level 5km Performance, Andrew M. Jones

All NMU Master's Theses

Elite and recreational endurance athletes routinely seek strategies to enhance sea level (SL) performance. Altitude (ALT) training continues to be an appealing approach. The primary purpose of this study was to measure the effect of a 12-day adventure running camp at ALT on 5 km time trial (TT) performance at SL. Secondarily, we explored changes in select metabolic and blood variables. We hypothesized an improvement in TT at SL. A group of five well-trained individuals (2 females) volunteered. TT, maximal oxygen uptake (VO2max), running economy (RE), and a complete blood count (CBC) were measured at SL before and …

7-Weeks Of Yoga Training And Its Effects On Flexibility, Rate Of Force Development, And Jump Height In Olympic Weightlifters, Andrew Ernst May 2016

7-Weeks Of Yoga Training And Its Effects On Flexibility, Rate Of Force Development, And Jump Height In Olympic Weightlifters, Andrew Ernst

All NMU Master's Theses

The purpose of the current study was to determine what effects 7-weeks of yoga training had on Olympic weightlifters flexibility, rate of force development, and jump height. Pre- and post-testing was performed consisting of flexibility and jump performance measurements. The participants performed a sit and reach test followed by a loaded overhead squat test with barbell. The overhead squat test was performed with reflective markers and recorded video to assess joint angles. A countermovement jump and snatch, at 80% of their one repetition maximum, was performed next to measure rate of force development and jump height. The participants then were …

A Novel And Rapid Staphylococcus Aureus Bacterial Identification Method Utilizing Immunomagnetic Beads And Single Cell Laser-Light Scattering, Kaylagh Hollen May 2016

A Novel And Rapid Staphylococcus Aureus Bacterial Identification Method Utilizing Immunomagnetic Beads And Single Cell Laser-Light Scattering, Kaylagh Hollen

All NMU Master's Theses

Staphylococcus aureus is the most commonly isolated human associated bacterial pathogen. It plays an important role in skin and soft-tissue infections, pneumonia, endocarditis, osteomyelitis, foreign-body infections, and sepsis. S. aureus diagnosis and treatment requires a minimum of 24-48. With this in mind, previous studies suggest that faster pathogen identification has been linked to improved patient outcomes. Improved patient outcomes including a reduction in hospitalization time, decreased risk of nosocomial infections, and decreased in medical costs. The impact of faster identification on patient outcome has led us to develop an alternative method of S. aureus identification via ImmunoMagnetic Separation (IMS) and …

Examination Of Cd133 And Cd147 As Cancer Stem Cell Markers, Christopher Mcmahon May 2016

Examination Of Cd133 And Cd147 As Cancer Stem Cell Markers, Christopher Mcmahon

All NMU Master's Theses

To date, as many as 14,000 patients in the United States per year are diagnosed with glioblastoma, the most common and most malignant primary brain tumor. Glioblastomas are characterized by their ability to evade treatment on many fronts, thus a novel approach to curative therapies is imperative. A population of cells with stem cell-like properties are found within glioblastoma tumors and drive their initiation and progression. Identification of extracellular markers on these tumor stem cells is thus paramount. The cell surface glycoproteins CD133 and CD147 were examined as potential markers of cancer stem cells found in glioblastoma. Here we found …

Analysis Of Tumor Specific Protein Expression In Glioblastoma Multiforme (Gbms) Tumors Through Immunohistochemistry, Amanda M. Wigand May 2016

Analysis Of Tumor Specific Protein Expression In Glioblastoma Multiforme (Gbms) Tumors Through Immunohistochemistry, Amanda M. Wigand

All NMU Master's Theses

GBM tumors are the most aggressive and, unfortunately, the most fatal form of brain cancer. GBM tumors with isocitrate dehydrogenase-1 (IDH1) mutation being expressed, lead to higher survival rates in patients that also have full resection of the tumor and chemotherapy. Without this mutation, it is thought that tumors have a higher expression of the protein Basigin and O6-methylguanine-DNA-methyltrasnferase (MGMT) present, causing it to be more aggressive and less responsive to standard care. The objective of this study was to understand the correlation between IDH1 mutation presence and the expression of Basigin and MGMT. The expression of these proteins was …
