Impedance Sensing Of N2a And Astrocytes As Grounds For A Central Nervous System Cancer Diagnostic Device, Fraser Traves Smith Grove
Impedance Sensing Of N2a And Astrocytes As Grounds For A Central Nervous System Cancer Diagnostic Device, Fraser Traves Smith Grove
Master's Theses
This thesis utilizes previously described manufacturing and design techniques for the creation of a PDMS-glass bonded microfluidic device, capable of electrochemical impedance spectroscopy (EIS). EIS has been used across various fields of research for different diagnostic needs. The major aim of this thesis was to capture cancerous and non-cancerous cells between micron sized electrodes within a microfluidic path, and to complete analysis on the measured impedances recorded from the two differing cell types. Two distinct ranges of impedance frequency were analyzed – the α dispersion range, which quantifies the impedance of the membranes of the cells of interest, and the …
Impedance-Based Detection Of Tissue Using A Multi-Electrode Device, Shane Killian Fleshman
Impedance-Based Detection Of Tissue Using A Multi-Electrode Device, Shane Killian Fleshman
Master's Theses
Melanoma skin cancer is the abnormal growth of the melanocytes – the pigmented cells located in the epidermis. The current gold standard diagnostic technique for determining whether a lesion is cancerous involves subjectively examining suspicious lesions and performing an invasive biopsy to confirm melanoma. This method may neglect some lesions or cause scarring from biopsies that turn out to be benign. Thus, impedance-based detection using a multi-electrode device was investigated as a noninvasive technique to diagnose melanoma skin cancer. The multi-electrode device was designed with 8 equally spaced Ag/AgCl electrodes surrounding one central electrode at a 5 mm radius. The …
An Exploratory Investigation Of The Effects Of Dragon Boating On The Psychosocial Well-Being Of Female Cancer Survivors, Clara Therese Louise Vanherweg
An Exploratory Investigation Of The Effects Of Dragon Boating On The Psychosocial Well-Being Of Female Cancer Survivors, Clara Therese Louise Vanherweg
Master's Theses
The purpose of this study was to prospectively examine the effects of dragon boat participation on the psychosocial well-being of female cancer survivors over time and compared with the population-based norms. Nine female cancer survivors belonging to the dragon boat team, SurvivOars, participated in the initial measurement process. The measurement packet was 21 page compilation of psychosocial questionnaires capturing demographics, quality of life, moods, depressive symptoms, perceived stress, self-esteem, self-efficacy, social support, physical activity levels, body image, and sedentary behaviors. After 8 weeks, 8 subjects completed the same follow-up questionnaire to assess changes in psychosocial variables over time. Scores were …
