Purposive sampling was used to recruit TCs in either the second or third year of one specific undergraduate, field-based teacher …

Polycystin-2 Is Cardioprotective Against Myocardial Infarction By Regulating The Calcium-Mediated Er-Stress Response, Virdjinija Vuchkovska

Dissertations

Patients with autosomal polycystic kidney disease (ADPKD) have an increased risk and worse outcomes after acute myocardial infarction, but the mechanism for this is unknown. Polycystin 2 (PC2), one of the two main proteins mutated in ADPKD, is a calcium permeant channel that localizes to the ER/SR. In non-cardiac cells, PC2 regulates the unfolded protein response (UPR) pathway under ER stress. However, whether PC2 is cardioprotective against ER stress is unknown. We found that PC2 expression increased in cardiomyocytes from human ischemic hearts and infarcted murine hearts. Cardiomyocyte-specific PC2 KO (PC2 KO) mice had worsened cardiac function after myocardial infarction …

“The Goal Is To Help The Community”: Motivations And Experiences Of Diverse Families In A Special Education Parent Advocacy Program, Diana Cruz

Dissertations

The Individuals with Disabilities Education Act (IDEA, 2004) entitles parents of eligible students with disabilities to meaningful participation in their children’s educational planning. Despite this mandate, many parents encountered barriers that limited their ability to participate in special education processes. These challenges were amplified for culturally and linguistically diverse (CLD) families who often lacked the social and cultural capital needed to navigate the system (Trainor, 2010b). Culturally and linguistically diverse parents experience systemic barriers such as limited interpretation, discrimination, and cultural differences that restrict their engagement (Buren et al., 2018; Doucet, 2011; Harry, 2008; Kalyanpur et al., 2000; Sanders-Smith et …
