Applying Transcriptomics For Technology Development And Conservation In North American Marine Organisms, Cory Von Eiff

Dissertations

RNA biology is a rapidly expanding field, with many avenues of discovery among marine organisms. In this study, we analyze both mollusks and sawfish. First, we perform an evaluation of sRNA biogenesis pathways throughout Mollusca, with emphasis on the easter oyster, Crassostrea virginica. Understanding these molecules prescribes RNAi-based gene silencing approaches, benefiting genetic investigation and biotechnology. Similar to other animal groups, mollusks have conserved microRNAs (miRNAs), with some shared with ecdysozoans and deuterostomes; however, there is no evidence of an endogenous small interfering RNA (siRNA) pathway. These results suggest that long double-stranded RNA (dsRNA)-based RNAi is not appropriate for gene …

Healing Circulos(Circles): Putting Our Educator's Mask First, Janet Martinez-Angeles

Dissertations

Educators play a pivotal role in supporting students throughout their educational journeys. In addition to academic instruction, they provide vital guidance for students' social, emotional, and personal development. They work tirelessly to help students navigate the complexities of education and life, often while shouldering multiple responsibilities and roles beyond the classroom. This dynamic contributes to high attrition rates and weakens the educational system. Much like the familiar safety instructions on an airplane, where passengers are reminded to put on their oxygen masks before assisting others, educators must be given the space, resources, and support to tend to their well-being before …
