Sit Less, Move More: A National Study Of Physical-Activity Behavior And Cancer, Stella O. Nwogugu

Dissertations, Theses, and Capstone Projects

Background: Physical activity is associated with lower risks of cancer, the second leading cause of death among Americans. Yet, sedentary behavior is the prevailing lifestyle for about 80% of American adults. Additionally, cancer survivors remain significantly inactive, even though physical activity has been shown to decrease risk of cancer and cancer recurrence, improve tolerance of cancer therapy, and reduce mortality. This research explores the relative impact of personal agency, social support, and key demographic variables on physical-activity behavior for a national sample of adults as well as how these relationships differ for cancer survivors and their counterparts.

Methods: Using the …

Porphyrinoids are robust heterocyclic dyes studied extensively for applications in medicine and as photonic materials because of their tunable photophysical properties, diverse means of modifying the periphery, and the ability to chelate most transition metals. Commercial applications include phthalocyanine dyes in optical discs, porphyrins in photodynamic therapy, and as oxygen sensors. Most applications of these dyes require exocyclic moieties to improve solubility, target disease, modulate photophysical properties, or direct self-organization into architectures with desired photonic properties. The synthesis of the porphyrinoid depends on the desired application, but the de novo synthesis often involves several steps, is time consuming, and results …
