Differences In Sexual Delay Discounting Among In-Treatment Adults With Opioid Use Disorder, Jonathan J.K. Stoltman

Graduate Theses, Dissertations, and Problem Reports

Previous research has found impulsive decision-making to be a core component of addiction (Moody, Franck, Hatz, & Bickel, 2016). One way to measure impulsive choice is through the use of a delay discounting task. The delay discounting task provides a way to measure choice of immediate, smaller rewards compared to delayed, larger rewards (Odum, 2011b). An emerging area of research in addiction science is the intersection of addiction and sexual health. Previous sexual delay discounting research has focused on whether attractiveness or STD risk can shift the likelihood of waiting until a condom was available (Johnson & Bruner, 2012). This …

Role Of Sox9 In Cancer Stem Cell Regulation In Lung Cancer Chemoresistance And Particle-Induced Carcinogenesis, Maria Voronkova

Graduate Theses, Dissertations, and Problem Reports

Lung cancer is a leading cause of cancer-related death worldwide. Every year it claims more lives than other common malignancies, breast, prostate, and colorectal cancers, combined. And despite recent improvements in disease diagnostics and treatment, drug resistance and tumor relapse remain major contributors to low patient survival. Both issues have been largely attributed to the existence of cancer stem-like cells (CSCs) or tumor initiating cells (TICs). CSCs are a small cell population within heterogeneous tumors that is inherently resistant to apoptosis, chemo- and radiation therapy. Thus, it is critical to elucidate CSC-specific signaling pathways and identify early biomarkers for therapeutic …
