Photon Irradation And Cisplatin Enrich Cancer Stem Cells In Ovarian Cancer, Ashley Antonissen

Electronic Theses, Projects, and Dissertations

High Grade Serous Ovarian Cancer (HGSOC) has a 5-year survival rate of less than 50%. Ovarian cancer is one of the deadliest gynecological diseases and the 7th most common female cancer worldwide. Ovarian cancer patients generally have a poor prognosis despite the relatively successful treatments. When conventional cancer treatments, such as cisplatin chemotherapy and photon irradiation, are administered, residual cancer stem-like cells (CSCs) can survive, leading to CSC enrichment. CSCs are a small population of cancer cells that exhibit stem-like characteristics: quiescence (slowing of the cell cycle), differentiation, proliferation, and self-renewal to regenerate new CSCs. We hypothesized that providing cancer …

Career Motivation As Mediator Between Cultural Self-Construal And Interest, Mengxuan Zhang

Electronic Theses, Projects, and Dissertations

Understanding the association between career motivations and interest-occupation congruence can help people with different cultural backgrounds make better career decisions. The goal of the study was to examine how cultural differences predicted interest congruence, and whether career motivation was a significant mediator in the prediction. I hypothesized that independent self-construal would be associated with internal career motivation most strongly (H1), while interdependent self-construal will be associated with interpersonal career motivation most strongly (H2). Additionally, internal career motivation would mediate the relationship between independent self-construal and interest congruence (H3), and whether internal career motivation mediated the relationship between interdependent self-construal and …
