Evaluating Soluble Axl As A Biomarker For Glioblastoma, Daniel Raymond Aug 2020

Evaluating Soluble Axl As A Biomarker For Glioblastoma, Daniel Raymond

All NMU Master's Theses

AXL, a receptor tyrosine kinase, is known to promote malignant phenotypes in various types of cancer. AXL overexpression is commonly observed in glioblastoma and correlates with a worse prognosis. Detectable in most biological fluids, the extracellular domain of AXL, sAXL, is the product of enzymatic cleavage by ADAM10/17. Here we used ELISA, BCA and BCG assays to characterize blood serum from 23 newly diagnosed GBM patients which was collected roughly 24 hours before and after surgery as well as every three months post-surgery, corresponding to follow-up treatment visits. Immunoblotting was used to determine relative AXL expression in 13 patient tumor …


Three Speeds Of Yoga And The Effects On Salivary Cortisol Levels In Female Nursing Students, Meagan Hennekens May 2018

Three Speeds Of Yoga And The Effects On Salivary Cortisol Levels In Female Nursing Students, Meagan Hennekens

All NMU Master's Theses

Purpose: Nursing students are prone to stress-related diseases, such as depression and anxiety, which are associated with chronically elevated cortisol levels due to the excessive firing of the Hypothalamic Pituitary Adrenal (HPA) axis. This study assessed three speeds of yoga and how they acutely affected salivary cortisol levels within female nursing students. Methods: Students participated in three yoga sessions cadenced at different speeds in a non-randomized order: (i) standard-speed yoga (SSY), (ii) high-speed yoga (HSY), and (iii) slow-speed yoga (SLSY). Each class integrated sequencing concepts from the brahmana/langhana strategy (BLS) and the Para Yoga Blueprint (PYB). Cortisol samples were …


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 …


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 …


A Cohort Study Investigating Autoantibody Levels During And After Infection With Influenza A Virus, Michelle Collins May 2015

A Cohort Study Investigating Autoantibody Levels During And After Infection With Influenza A Virus, Michelle Collins

All NMU Master's Theses

Antinuclear autoantibodies (ANAs) are present in all individuals. In those with autoimmune diseases they are routinely present in elevated levels. Although the nature and development of autoimmune diseases are not fully understood there are many hypotheses as to possible causes of an autoimmune disorder. One possible cause is viral infections. The scope of this thesis study was to examine if autoantibodies levels in individuals without autoimmune disorders increase during or after infection with influenza A virus. Blood was collected from volunteers (n=11) at time intervals of 0, 7, 42 and 63 days, respectively. Antibody levels were measured using ELISA assays …
