Identification Of Sall4 Expressing Islet-1+ Cardiovascular Progenitor Cell Clones, Andrea Gabrielle Monteon

Electronic Theses, Projects, and Dissertations

The utilization of cardiac progenitor cells (CPC) has been shown to induce favorable regenerative effects. While there are various populations of endogenous CPCs in the heart, there is no consensus regarding which population is the most ideal for cell-based regenerative therapy. Identifying an Islet-1+ (Isl-1+) early-stage progenitor population with enhanced stemness, multipotency and differentiation potential would be beneficial for regenerative therapy. Spalt-like transcription factor 4 (SALL4) plays a role in embryonic development as well as proliferation and expansion of hematopoietic progenitor cells. We hypothesize that SALL4 will be co-expressed in Isl-1+ cardiac progenitor cell clones isolated from human cardiac tissue …

Socioeconomic Landscape Restructuring Caused By Property Appreciation Rates, Abner Garcia

Electronic Theses, Projects, and Dissertations

Real estate property has historically been considered the bedrock of the American Dream and a primary method used to build wealth. However, homeownership has not been attainable for many people because property appreciation rates have consistently exceeded income growth. Available research indicates that rapid appreciation rates pressure low to average income earners out of their counties of residence towards more affordable counties’ residencies. This creates a problem where the receiving counties have increased demand and prices which starts a cycle of migration for lower income populations. Shifting populations can change the economic and demographic characteristics of counties. Previous research that …

Assessing Urban Canopy Program In Redlands California, Joseph Angel Rocha Iv

Electronic Theses, Projects, and Dissertations

Climate change can cause major environmental and human health issues especially in lower income and minority communities (Ros et al. 2020; Bethel et al. 2022). Although studies note tree coverage alone cannot solve all climate related problems (Pataki, et al. 2021; Ross, 2021), tree coverage does provide alleviation for climate change related factors (Free-Smith, et al. 2004). Some ways trees can combat climate change is through improved air quality, improved water quality, and decreasing impacts of Urban Heat Island Effect (UHIE) (Nowak et al. 2018; Liu, Liu, 2021; Wang, Zhao, et al 2017). Although throughout the United States there is …

Knockdown Of C. Elegans Nad Kinases Nadk-1 Or Nadk-2 Induces An Antioxidant Response Without Affecting Lifespan, Henry Gong

Electronic Theses and Dissertations

Nearly all multicellular organisms show changes in redox balance with aging leading to oxidative damage of macromolecules. This study investigated the role of the [NADP⁺]/[NADPH] redox couple in aging. This redox couple plays an important role in maintaining tissue redox balance and becomes slightly more oxidized in aged tissues. NADPH is a major source of reducing equivalents for enzymes that detoxify hydrogen peroxide. However, catalase detoxifies hydrogen peroxide independently of NADPH. But catalase is absent from mitochondria, a major source of hydrogen peroxide, where instead glutathione plays the major role in hydrogen peroxide detoxification in an NADPH-dependent manner. …
